Utility rack and rail system for vehicle

[0001] This application claims priority to U.S. provisional patent application No. 61/921,265 filed Dec. 27, 2013, and U.S. provisional patent application No. 61/935,076 filed Feb. 3, 2014, the entire contents of which are hereby incorporated by reference in their entirety.

[0002] This disclosure relates generally to utility racks as may be used with motor vehicles such as pickup trucks.

[0003] Full-size pickup trucks are generally available with several different types of beds attached. The bed lengths typically specify the distance between the inside of the front end of the bed and the closed tailgate. Some standard bed sizes for long, full-size beds are generally 6.5 ft (2.0 m) or 8 ft (2.4 m) long and compact truck beds are generally 5 ft (1.5 m) long. A typical bed width for full-size truck beds is 48 in (1.2 m) between the wheel wells (minimum width), however widths of full-size truck beds may be between 60 in (1.5 m) and 70 in (1.7 m). Compact truck beds are also available. Most compact truck beds are approximately 50 in (1.3 m) wide. As described herein, references to a longitudinal aspect of a structural part or element refer to the length of the truck bed and references to a lateral aspect of a structure or part refer to the width of the truck bed, unless otherwise stated. References to “inboard” parts or elements refer to items which are nearer or more proximate to the longitudinal centerline of the truck bed. Outboard elements are farther away from inboard elements. Reference to items that are “forward” refer to parts or structures nearer the cab of the truck and “rearward” items refer to parts or structures nearer the rear or tailgate of the truck.

[0004] A standard bed in a pickup truck has fender wells on the inside of the bed such that the fenders cannot be seen on the outside of the bed. Other pickup trucks have a flareside or stepside bed where the fenders are provided on the outside of the bed. Sometimes the truck bed has a well-body or a style-side body. The truck bed is enclosed on the sides with body panels, usually made from pressed steel. A hinged rear tailgate is also common. Rear indicators and brake lights are usually fitted to the rear corners of the body in a manner similar to sedan rear lights.

[0005] Known truck bed rails presently available may be installed by vehicle operators and dealers along the tops of the truck bed side walls. Many truck beds include stake pocket holes which are used to attach the rail to the truck bed side walls. A stake hole may be a rounded or squared opening along the top of a truck bed side wall. The vehicle operator may place the base of the rail over and into the stake holes and bolts the rails to the bed using bolts and washers. Sometimes, a user will drill mounting holes in the truck bed side walls where the rails should be mounted. Often, a gasket and rubber extender will be added to the bed rail's mount that lets the mount fit into the stake hole of the truck. Once the bed rails have been added to the mount, the rails are bolted onto the truck with an Allen wrench.

[0006] Vehicle operators may wish to carry items in their vehicle which may be very long, in some instances longer than the length of the truck bed. Such long items may include lumber, ladders, pipes or other similarly long items. Because these items are too long for pickup truck beds, the vehicle operator may wish to secure them some distance above the truck bed. Accordingly, it may be desirable to have racks which extend a distance above the truck bed, as well as racks which may be secured or stabilized to the cabin roof of the truck.

[0007] The following simplified summary of the disclosure provides a basic understanding of some aspects of the invention. This summary is not an extensive overview of the embodiments of the disclosure. It is not intended to neither identify key or critical elements of the embodiments of the disclosure nor to delineate the scope of the disclosure. Its sole purpose is to present some concepts of the various embodiments, in accordance with the disclosure, in a simplified form as a prelude to the more detailed description that is presented later.

Hoops may further include a lateral cross bar, the lateral cross bar substantially elongate, each end of the lateral cross bar connectable with one of the elbows proximate to the lateral end of the elbow. The first and second inner clamping surfaces of the clamps may be securable about the upper bar element of the stanchion between the first and second standposts, and the first and second inner clamping surfaces may have a conforming profile with an outer surface of the clamping portion of the upper bar element. The first and second inner clamping surfaces of the clamps may be securable about a side rail, and the first and second inner clamping surfaces may have a conforming profile with an outer surface of the side rail of the upper bar element. The clamp locking mechanism for each clamp may include a pivotable lever connected to the first jaw and pivotable with respect to the first jaw, a loop connected to the pivotable lever, and a hook connected to the second jaw and positioned such that as the first and second jaws are closed the loop may forcibly pressed against the hook as the lever is pivoted away from the second jaw thereby forcing the first and second jaws together. Each elbow may be pivotably connectable with one of the leg segments. At least one elbow may include a rod pivotable between a stored and a deployed position, the rod positioned substantially within a lateral channel in the stored position, and the rod secured in a substantially vertical orientation in the deployed position. The elbow may further include a cross channel pin extending across a confluent channel region between the lateral channel and a vertical channel, and the rod may further include a thru slot, the channel pin extending through the thru slot. The rail system may further include an upper hoop bar, the upper hoop bar substantially elongate and attachable at each end with an elbow, the upper hoop bar oriented substantially parallel to at least one of the side rails when attached to elbows on each end of the upper hoop bar, and each elbow may include a cross pin projecting from the elbow, each end of the upper hoop bar having a mouth matable with the cross pin.

[0062] Embodiments of a rail system may also include a pair of elevated rails. Each elevated rail may include at least one elongate rail oriented substantially parallel to at least one side rail, at least one rod sleeve dimensioned to internally receive a rod in its deployed position, and a rod securing mechanism for securing the rod within the at least one rod sleeve.

[0063] Embodiments of a rail system may further include a bed divider, and the bed divider may include a cross bed bar, the cross bed bar substantially elongate, and a plurality of bed divider clamps, each bed divider clamp attached to an end of the cross bed bar, the be divider clamps operable to attach to a side rail. The rail system may also include a locker top including a pair of hinges connectable with the cabin side rail, the locker top, the bed of the pickup truck, and the bed divider defining an interior space, the locker top pivotable between an open position and a closed position. In various embodiments of the rail system, the side rails may have a substantially cylindrical profile.

[0064] With reference to FIG. 1, a vehicle 10 for which embodiments of a rail system may be utilized with may include a pickup truck having a truck bed 12, as illustrated in the figures. Pickup truck bed 12 may be substantially composed of a left bed sidewall 14, a right bed sidewall 15, and a cabin-side or cabside wall 16. Truck bed 12 may further include a draw-down gate 18 which may be opened by the vehicle operator in order to facilitate the insertion or removal of items to be stored in truck bed 12. Vehicle 10 may also include taillights 20 controlled by a taillight control system 21. Embodiments of a rail system are illustrated in the figures as applied or attached to a pickup truck 10 having a truck bed 12, but it should be understood and appreciated by those of ordinary skill in the art that embodiments of rail systems disclosed herein may be suitably attached or utilized with other motor and non-motor vehicles, including for instance vans, carriages, trucks without truck beds, trucks with covered or enclosed truck beds, or other known or to be developed vehicles.

[0065] As illustrated, a rail system may include a first side rail 22, a second side rail 24, and a cab side rail 26. These side rails may be mounted along a top edge 13 of truck bed side walls 14, 15. Furthermore, side rails 22, 24 may be mounted on side walls 14, 15 by a plurality of stanchions 30, 32. In order to permitting the sliding and interexchange of components of the rail system, including for instance the various embodiments of clamps disclosed herein, rails 22, 24, 26 may be substantially cylindrical, however the other shapes are also contemplated within the scope of the disclosure. Additionally, the cylindrical rails 22, 24, 26 may be at least partially hollow such that there is a distinct inner and outer diameter, at least for instance near the ends of the rails.

[0066] FIG. 2 illustrates a stanchion 30, which in some embodiments may be the rear stanchion 30 which may be distinct from the forward stanchion 32. While in some embodiments stanchions are interchangeable, in other embodiments one or more rear stanchions 30 may be distinctly designed from forward stanchions 32. Stanchion 30 may include a base platform 36, a fore end standpost 38, and a rear end standpost 40. Standposts 38, 40 may support an elevated bar element 42 provided at an elevated distance from the top surface 37 of base platform 36. Base platform 36 may further include a platform extension 44 which may itself include a channel 46, which may be substantially centered within extension 44. Elevated bar element 42 may be substantially elongate having opposed ends, including a rail side end 48 and opposing tail side end which may include an end cap 50. Rail side end 48 may be attached to one of the side rails 22, 24. FIG. 1, for instance, illustrates first side rail 22 attached to stanchion 30, and second side rail 22 attached is stanchion substantially the same as stanchion 30. At or proximate to rail side end 48, a securing element 49 may be included to attach rail 22 or 24 to stanchion 30. Securing element 49 may be a pin, nut and bolt, set screw fitting, welding, or another similar securing device. As shown, rail side end 48 may include a projecting portion having a diameter with a smaller diameter than an inner diameter for side rail 22, 24, and thus side rail 22, 24 may slid over the projecting portion of rail side end 48. On the opposing end of elevated bar element 42 may be end cap 50, various embodiments of which are further discussed herein, including solid surface end caps, end caps with a light reflecting face 52, caps with incorporated lights, and other embodiments.

[0067] FIGS. 3 and 4 illustrate an embodiment of rearward stanchion 30 including clamps 54 which may be attached to the sidewall 14 of truck bed 12. Clamps 54 may have depending tab-like elements 56 that are matable within channel 46 of base platform 36. It is contemplated that stanchions 30, 32 may be attached to sidewalls 14, 15, 16 by known or to be discovered securing devices or methods, including screws and adhesive material, However clamps 54 may be utilized in order to effectively secure stanchions 30, 32 while allowing stanchions to be easily removable, and to prevent unnecessary or unintentional damage to truck bed 12. Alternatively, clamps 54 may be utilized in addition to known or to be discovered securing devices or methods. As particularly shown in FIG. 4, clamp 54 may include a clamp jaw 57 with a depending tab 56. Depending tab 56 may mate within channel 46 of platform extension 44. For reference, cab 9 and sidewall 14 are also illustrated in FIG. 4.

[0068] FIGS. 5A and 5B further illustrate embodiments of stanchion 30. In this embodiment, stanchion 30 is shown to include channels 51A, 51B internally disposed through standposts 38, 40. Accordingly, stanchion 30 may be attached to the bed sidewalls via a bolt system which may cooperate with a threaded knot in channels 51A, 51B. Additionally, set screw 49A may be inserted into set screw hole 49, as illustrated by arrow 47A, thereby securing side rail 22 with end 48 of upper bar element 42.

[0069] FIGS. 6-8 illustrate embodiments of end caps 52 for use with embodiments of stanchions 30. In the embodiment illustrated in FIG. 6, the opposed end of elevated bar element is relatively uniform surface. At least a portion of an end surface region 53 may be light reflective such that when light strikes that surface region 53, said light reflects back to the source. This reflective feature may, for instance, improve safety that vehicle 10 may be more easily identified at night by headlights from another vehicle approaching vehicle 10 from the rear. FIG. 7 illustrates an embodiment of end cap 52 including a plurality of lights 54A, 54B, which may be LEDs or other known or to discovered electrically operated lights. With reference to FIG. 8, a light system 56 is shown as may be utilized with a rearward stanchion 30 which may have lights 54A, 54B. As part of light system 56, stanchion 30 may be electrically coupled via electrical line 58 to light control line from a light controller 21 to taillight 20. Light controller 21 may be manually operable by the vehicle operator, or alternatively light controller 21 may be synched with taillight 20 such that illuminations of taillight 20 are matched by illuminations of end cap lights 54A, 54B. In additional embodiments, one or more additional side rails such as cabin rail 26 may be attached at or proximate to end cap 50 thereby providing a side rail, similar to cabin rail 26 for instance, extending across a tailgate for instance between two stanchions 30 provided at or proximate to the rear of vehicle 10.

[0070] FIGS. 9A and 9B show embodiments of the rail system proximate to cab side rail 26 and forward stanchions 32. As previously discussed, stanchions 30 and 32 may be interchangeable in some embodiments, while in other embodiments stanchions 30 and 32 are uniquely designed. Additionally, some components of forward stanchions 32 may be utilized with rear stanchions 30, and vice versa. Forward stanchions 32 may include a coupler element 60A which may be complementary to coupler element 60B at or proximate to a terminal end 62 of cab side rail 26. Furthermore, coupler elements 60A, 60B when combined may be attached by screws, bolts, or other known or to be discovered fasteners. Couple element 60B may be fitted into coupler element 60A of forward stanchion 32, as illustrated for instance by arrow 61. Opposing terminal end 63 may have a similar coupler for the right side, forward stanchion (illustrated without reference numerals in FIG. 1). In some embodiments, end unit 64 may be independent of cab side rail 26. Complementary couplers 65A may also operate in conjunction with couples 65B in cab side rail 26. Screws, bolts, or other fixing elements may be combined with couples 65A, 65B.

[0071] Generally referring now to FIGS. 10-26, embodiments of hoops, clamps, and associated components are provided which may be included as part of a rail system in accordance with the disclosure. FIG. 10 illustrates a plurality of hoops 70 mounted on, or attached to, side rails 22, 24. Three hoops 70 are provided in the illustrated embodiment, including two end hoops which are substantially similar, and a middle hoop sharing several common characteristics as the end hoops. It should be understood and appreciated that in some embodiments all hoops 70 are substantially identical and interchangeable, while in other embodiments all three hoops 70 have unique characteristics or components from one another, and while in yet additional embodiments two hoops 70 may be substantially identical while a third hoop 70 may have unique characteristics or components. Additionally, the illustrated embodiment shows three hoops 70, however it should be appreciated that fewer or greater hoops 70 are contemplated within the disclosure.

[0072] Hoops 70 may generally include two legs 72, an elbow 74 connectable with each leg, a lateral cross bar 76 provided between adjacent elbows, and clamps 78 for releasably connecting each leg to a side rail 22, 24. Elbows 74 are generally provided to connect adjacent legs 72 with a lateral cross bar 76. In some embodiments, hoops 70 may generally be described as “U Shaped” however it should be understood and appreciated that a variety of shapes of configurations are contemplated in accordance with the disclosure. Upper hoops bars 79 may also be provided and may generally be connected with a first elbow 78 of a first hoop 70 with a second elbow 78 of a second hoop 70. Additionally, a rod 80 may be provided in one or more elbows 74. Rod 80 may be pivotable between a stored position and a deployed position, with the stored position generally disposing the rod 80 within elbow 74 while the deployed position generally positions the rod 80 upwards in a substantially vertical orientation. Further details of various embodiments of hoops 70 and their associated components are further described herein.

[0073] FIG. 11 illustrates embodiments of clamps 78, 78A as may be utilized for connecting one or more rods 72 to side rails 22, 24. As illustrated, in some embodiments clamp 78 may be attached to upper bar element 42 of a stanchion 30. Accordingly, clamp jaws may extend within and through a stanchion opening 41, defined as the opening between base platform 36, upper bar element 42, and standposts 38, 40. The distance between base platform 36 and upper bar element 42, which may be defined as the clamp jaw clearance height, should be sufficient to permit the clamp jaws to extend through opening 41, and in one embodiment the distance between base platform 36 and upper bar element 42 may be approximately 2 inches. As also illustrated, clamp 78A may be alternatively attached directly to a side rail 24A. In one embodiment, clamps 78 for end hoops 70 are connected to stanchions 30, while the clamp 78A for the middle hoop 70 is attached to a side rail 24A.

[0074] FIG. 12 shows one embodiment of hoop 70 for a rear view as attached to a pickup truck bed 12. The height of hoop 70, as defined by the distance from the base of hoop 70 proximate to clamps 78, is substantially higher than the height of the passenger cabin 9 of the vehicle. It should be appreciated, however, that other heights are contemplated as various embodiments of the rail system may be desired by the vehicle operator. For instance, the hoop height may be approximately the same as the height of the passenger cabin 9, while in other embodiments the hoop height may be less than the passenger cabin 9. Additionally, legs 72 may be oriented at an inward angle such that the distance between corresponding elbows 74 of a hoop is less than the distance between corresponding clamps 78 of a hoop. This angle is illustrated in contrast, for instance, to the substantially vertical orientation of rods 80. As will be further discussed herein, legs 72 may be pivotable at their connection point with elbow 74 such that legs 72 may fold into a position that is substantially parallel with an attached lateral cross bar 76. This pivoting feature allows the vehicle operator to easily store each hoop 70 in a compact area.

[0075] A first embodiment of a clamp 78 is illustrated in FIGS. 13 and 14. In this embodiment, clamp 78 is integrally connected to a leg 72. Clamp 78 may include a pair of locking clamps 82, 84 hinged together above a pivot point 86. A first clamp jaw 82 may be stationary while a second clamp jaw 84 may be pivotable about pivot point 86. First clamp jaw 82 may include a first clamping surface 83 and second clamp jaw may include a second clamping surface 85 opposed to the first clamping surface such that as clamp jaws 82, 84 close around either upper bar element 42 of stanchion 30 or one of the side rails 22, 24, the clamping surfaces 83, 85 are conformingly shaped to the outer surface of the upper bar element or rail to be clamped and can snuggly fit around either the upper bar element or rail to be clamped.

[0076] FIG. 13 demonstrates an embodiment where clamp 78 is attached to upper bar element 42 of a stanchion 30. Second, pivotable clamp jaw 84 may have a defined jaw span 84a between a first end of clamp jaw 84 proximate a hook 96 and a second end of clamp jaw 84 proximate pivot point 86. Furthermore, a jaw distance 84b may be defined as the thickness of second, pivotable jaw 84 which can be measured as the distance from the inner clamping surface 85 and a directly adjacent outer surface of clamp 84 in an orthogonal direction. Accordingly, jaw distance 84b may be less than the clamp jaw clearance height in order to permit jaws 82, 84 to close around the to-be clamped surface, and yet jaw span 84a may be larger than the clamp jaw clearance height 41B such that should pivotable jaw 84 become detached during operation, then clamp 78 still generally remains in space since it is trapped within station space 81.

[0077] Various mechanisms may be provided to close and lock jaws 82, 84 and, indeed, the difference in the locking mechanisms is at least one such difference between the embodiments of clamps 78 illustrated between FIGS. 13 and 18.

[0078] In one clamp locking mechanism embodiment, as shown in FIGS. 13 and 14, clamp 78 may include a release lever 88 pivotable about a clamp release pivot point 92. In this embodiment, in order to release jaw 84 from jaw 82, a user may move release lever 88 away from the clamp body 91. Accordingly, the release lever operates about a release pivot point 92, appropriately fixed to clamp body 91. Clamp 82 may further include a hook and loop subset whereby lever 88 operates on loop 94, and loop 94 may extend about hook 96. Hook 96 may be formed at or proximate to the end of pivotable jaw 84. Loop 94 may be pivotally mounted to lever 88 a lever pivot point 95. Lever 88 may be movable in a release direction 88A and loop 94 may be movable towards the pivotable jaw 84 and hook 96. A terminal end of loop 94 may be thereafter swung away from the hook and released from hook 96. The hook and loop subset may thereby establish a compression, friction grip established by jaw surfaces 83, 85 on the upper bar element 42 of stanchion 30. Clamp 78 may be removed from the clamped surface by moving lever in direction 88A followed by moving loop 94 away from hook 96, as illustrated by arrow 94A. As loop 94 is moved in direction 94A away from hook 96, pivotable jaw 94 may move about pivot point 96 away from stationary jaw 82 thereby permitting the release of clamp 78. Polypropylene or another material may be provided in order to facilitate a stabilized connection between loop 94 and hook 96 when the jaws are in the closed position.

[0079] FIGS. 15-17 illustrate clamp 78 with another embodiment of a locking mechanism. Release lever 88 may include a lock stand passage 89, and a lock stand bar 102 may extend through lock stand passage 89. Proximate to a distal end of lock stand bar 102 may include a lock stand passage 104 dimensioned to receive a key 106, which may be insertable into lock stand passage 104 such that insertion of key 106 prevents the removal of lock stand 102 from lock stand passage 89 thereby securing lever 88. In some embodiments loop 94 may dog-legged as evidence by an angle at a transition point 107 for loop 94. Furthermore, loop 94 may be hinged a loop hinge point 106 proximate to a lower end of lever 88. Thus, as lever 88 is moved in direction 88A, loop 94 may swing out of hook 96 and further rotated in direction 94A.

[0080] FIG. 18 illustrates an additional embodiment of clamp 78 with an additional embodiment of a locking mechanism. Clamp jaws 82, 84 may be attached to one another, by one or more threadable connectors 109 provided in one or more internally threaded passages 108. A plurality of threadable connectors 109 and passages 108 may be provided to firmly secure jaws 82, 84 together, and a jaw pivot point may or may not be provided in such an embodiment.

[0081] As discussed above, other cross section shapes or profiles are contemplated for rails 22, 24, 26 as well as upper bar element 42, including for instance a square or triangular cross section. Thus, clamping surfaces 83, 85 may be conformingly shaped as is appropriate for the surface they will be clamped to. Furthermore, as rails 22, 24, 26 may not necessarily have conforming cross sectional shapes or profiles with each other or with upper bar element 42, the conforming jaw profiles defined by jaw surfaces 83, 85 may be uniquely provided for each unique surface shape to be attached to. However, in some embodiments all profiles may be substantially the same with one another in order to facilitate interchangeability of clamped-on components such as hoop 70. Additional clamped-on components are disclosed herein, and it should be understood that clamps associated with other clamped-on components may be interchangeable between various clamped-on components. For instance, a hoop clamp 78 may be usable with, or substantially the same as, bed divider clamp 226 (see FIG. 28) and vice versa. Embodiments which permit interchangeability of clamp types with clamped-on components will benefit from reduced manufacturing costs.

[0082] FIG. 19 shows an embodiment of a hoop 70 unattached from truck bed 12. As previously described, embodiments of hoop 70 may include a pair of legs 72 each connected to an elbow 74, each elbow 74 connected by a lateral cross bar 76, and each leg 72 connected to a rail 22, 24 or stanchion 30 by a clamp 78. Each elbow 74 may include a rod 80 pivotable between a stored position and a deployed position. Legs 72 may be attached to clamps 78 a terminal end 120 of the leg. Lengths of legs 72 may be expandable in some embodiments by adding additional segments to extend the tube segments of respective legs 72. Otherwise, rail systems may be manufactured with various predetermined lengths and vehicle operators may purchase their desired lengths according to the requirements of the rail system, dimensions of their vehicle 10, and other similar criteria. Rail systems may also be custom ordered by the vehicle operator. Similarly, rails 22, 24, 26 may be extendable by providing longer rails, cutting the rails to size, or providing rail-to-rail inserts for the tube segments of the rails.

[0083] Each leg 72 may substantially elongate with a terminal end 120 defined at or proximate to clamp 78 and an upper end having an upper leg segment 122 connectable with a lower elbow segment 124 of elbow 74. A lateral elbow segment 126 may be defined at or proximate to a lateral end 125 of lower elbow segment 124. In some embodiments elbow 74 is substantially oriented at 90 degrees, while in other embodiments such as the illustrated embodiments, the elbow segment is obtuse in consideration of the inward angling of legs 72. It should also be appreciated that lateral elements, such as lateral bar 74, may be substantially horizontal in some embodiments, however some lateral components may be tilted with respect to the horizon especially, for instance, if one leg 72 has a greater length than another leg 72 of a hoop 70.

[0084] FIGS. 20 and 21 illustrate various viewpoints of elbows 74 without rod 80. Elbow 74 may include a lateral channel 132 a substantially vertical channel 130, with the channels having a confluent channel region 133 defined at or proximate to the corner or apex of elbow 74. In the illustrated embodiment the corner of elbow 74 is shown as substantially 90 degrees, but it should be appreciated that the disclosure is not limited to 90 degrees and varying angles are contemplated within the disclosure. A rod locking mechanism may be provided in order to lock rod 80 in either the stored position or the deployed position. One or more thumb screw locks 136 may be provided as part of the rod locking mechanism. In some embodiments, lower elbow segment 124 and upper terminable end 122 of leg 72 are pivotably attached such that leg 72 may pivot about a leg pivot axis, provided at or proximate to the area where lower elbow segment 124 and upper terminable end 122 are joined. This pivoting may facilitate legs 72 to fold up or collapse against lateral bar 76 thereby facilitating easy storage of hoop 70 when not in use. Elbow 74 may further include a longitudinally projecting stub 134 which may be utilized for attachment with an upper hoop bar 79. FIG. 21 shows an embodiment of elbow 74 with a singular stub 134, while FIG. 20 illustrates an embodiment of elbow 72 with dual, opposing stubs. An embodiment with dual opposing stubs may be particular useful in three hoop 70 rail systems, with dual opposing stub elbows provided for the center hoop, and single stub elbows provided for end hoops.

[0085] FIGS. 22A-22C illustrate rod 80 included with elbow 74, and more particularly FIG. 22A illustrates rod 80 in a deployed position, FIG. 22C illustrates rod 80 in a stored position, and FIG. 22B illustrates a transition position of rod 80 between the deployed and stored positions, as demonstrated by arrows 141A and 141B. Rod 80 may have an elongated thru slot 144 extending through a portion of rod 80. In a stored position, at least a portion of rod 80 may be secured within lateral channel 132, while in the deployed position at least a portion of rod 80 may be secured in vertical channel 130. As part of a rod locking mechanism, provided to secure rod 80 within the respective channels, a cross channel pin 146 may be fixed in elbow 74 and may extend through the thru channel slot 144 proximate to the confluent region 133 of channels 130, 132. As rod 80 moves, channel slot 144 also moves over cross channel pin 146. Said another way, although cross channel pin 146 remains stationary, cross channel pin 146 may be said to move along thru channel 146 as rod 80 is moved.

[0086] In the deployed position, as rod 80 is moved from the stored position to the deployed position, it may be moved completely downward to the end of vertical channel 110 thereby retaining rod 80 in a substantially vertical orientation. Thus, in the deployed position cross channel pin 146 may be positioned at or proximate to the top 144A of slot 144 thereby providing upper stability to rod 80 while lower stability may be provided by the position of rod 80 in channel 110. In some embodiments the rod length 80A is less than the lateral channel length 132A, thereby permitting rod 80 to be substantially encompassed by lateral channel 132 in the stored position.

[0087] FIG. 23 illustrates connections between elbow 74 and leg 72, between elbow 74 and lateral cross bar 76, and associated pivoting features of these connections. Terminal end 151 of elbow may have a complementary mated fit with lateral cross bar 76. In order to keep cross bar 76 attached to elbow 74, a locking bore or passage 152 may be dimensioned to receive a locking key 150. As key 150 is inserted into bore passage 152, illustrated in the figure by arrow 150A, lateral cross member 76 may be secured with elbow 74. Similarly, as key 150 is removed then lateral cross bar 76 may be removed as illustrated by arrow 76A. At the lower end 124 of elbow, a pivotal coupling may be established with upper end 122 of hoop leg 72. Elbow 74 may have a plate-like stem 162 extending from its lower vertical elbow segment. Stem 162 may have a locking passage and a pivot pin may be placed through the end upper end 122 of hoop leg 72 into the locking bore. As the pin is withdrawn from locking bore 162, elbow 74 may freely swing downward as illustrated by arrow 165. Elbow 74 may be secured with hoop leg 72 by an additional key 154 operating in conjunction with key bar 156. Key 154 may be moved into key bar 156, as illustrated by arrow 154A, thereby locking the lower vertical segment 124 of elbow 74 into the upper segment 122 of hoop leg 72. Accordingly, there may be complementary couplers between elbow 74 and upper bar terminal ends 122 of hoop leg 72. It should be appreciated that, generally speaking, vertical channel may be oriented substantially vertically while the proximately positioned leg 72 will be angled in some embodiments. In contrast, lateral channel may be substantially aligned with the orientation of the connected lateral cross bar 76, which may be a substantially horizontal orientation.

[0088] Elbow 74 may be a substantially right angle elbow that, accordingly, defines a common plane formed by lateral elbow portion and the vertical elbow portion. When key 154 is withdrawn for key way 156, elbow 74 is rotatable within the common plane defined by lateral extension of elbow 74 and leg 72. With the clamp 78 loosened, and key 156 removed, hoop 70 may be collapsible and storable, for instance within truck bed 12. Various known or to be developed locking mechanism may be accordingly utilized for locking hoop legs 72 with elbows including, for example, spring clip locks, pin locks, thumb screw locks, or complementary detents. A spring clip lock is typically a cotter pin. A nut and bolt, with or without a locking nit, may also be used. A pin lock is a lock having a cylindrical bolt which moves into a lock passage, which locks one system to another system by inserting the cylindrical bolt into the lock bore. A thumb screw lock is generally shown in FIG. 24. A detent would involve just the end of the thumb screw lock 136 in FIG. 24 and a small complementary cavity in the other locking element. The protruding detent is complementary to the cavity detent. An elbow member-to-upper loop leg locking system can be used with these features. Similarly, the extendable rod 80 may have a rod-to-elbow locking system

[0089] With reference now to FIG. 24, a cross sectional view of an embodiment of an elbow 74 is illustrated. In FIG. 24, rod 80 is provided in a deployed, substantially vertical orientation and its lower end is captured in the open mouth tube formed in the lower leg segment of elbow 74. A thumb screw lock 136 may secure rod 80 to elbow 74 in one of the elbow channels. Thumb screw lock may include a user-actuatable surface 136A which, when turned, may cause the bolt to move on threads 136B and to friction compress the contact point 136C against rod 80. As one alternative to a thumb screw, contact 136C may be a complementary set of detents. Rod 80 may include a distal end which may be rounded.

[0090] Elbow 74 may further include at least one stub 170 with a laterally movable cross pin 172. Cross pin 172 may be longitudinally biased on one direction by a spring or bias system 176. Other systems to bias the pin 172 to one longitudinal end or the other longitudinal end of the cross pin slot 174 may be used. The bias spring may be outboard of the stub 170. Bias 176 acts on movable pad 178 to keep cross pin 172 at one end of the cross pin slot 174. Pin 172 can be moved to the other end of the cross pin slot 174 by pin actuator surface 184 of lever release 180. In the illustrated embodiment, release lever 180 has a pivot intermediate pin cam surface 184 and a user actuatable surface 182. Other designs of the release lever 180 may be provided as long as when the user exerts force on the release, cross pin 172 moves to the other end of the cross pin slot 174, against the force of bias spring 176. Lever leg 180 moves in direction 182A and pin 172 moves to the right in FIG. 24. Another pin release system may bias cross pin 172 to the right, and use a level lever release acting on the right side of cross pin 172 to force the pin against a right-side directed bias. The bias may be spring, air or water pressure, a leaf spring or a coil spring.

[0091] Cross pin 172 may be sized to fit into a pin capture opening formed by open mouth 194, having a wide mouth dimension, leading to a narrow throat 196, with a narrower dimension (but sufficiently sized to pass pin 172 there through), and leading to a cross pin capture slot 198 which may permit the cross pin to move longitudinally in the slot 198. When the cross pin 172 is at slot edge surface 210, the elbow may be locked onto the upper bar 79 of the rack and rail system. When the cross pin is moved by the user to slot edge or surface 211, the upper bar 79 can be moved upward and withdrawn from the stub 170. The pin capture opening formed by spatial elements 194, 196, 198 is defined by a stem 192 at terminal end 190 of upper bar 79.

[0092] Pin capture opening 125 may have an open mouth with a mouth span 194, a narrow throat 196 and a cross pin capture slot 198. Narrow throat 196 may have a smaller dimension or smaller span compared with the larger mouth span 194. Pin capture slot 198 is at least dimensionally sized to retain cross pin 172 therein. Further, cross pin capture slot 198 may extend longitudinally such that cross pin 192 can move forward and back with cross pin capture slot 198. In operation, the user forces terminal end 190 and specifically stem 192 down into the longitudinal slot formed in the longitudinally extending stub 170. The cross pin snaps into the pin capture opening due to the bias on the cross pin. Alternatively, the cross pin may extend inboard (or outboard) of the stub (inboard being towards the truck bed interior) and the cross pin would, in that case, still enter into mouth 94 through narrow throat 196, and into cross pin capture slot 198. In order to release the terminal end 190 and stem 192 from longitudinal stub 170 of elbow 174, the user may move user actuatable surface 182 in direction 182A, and pin actuator surface 184 moves cross pin 72 in slot 174 and also moves the cross pin 172 within cross pin capture slot 198.

[0093] Cross pin capture slot 198 may have a pin capture region, as shown in the left section of FIG. 24 (near surface 210) and a release region opposite the capture region. Capture region for pin capture slot 198 may be defined near surface 210. Release region may be formed by surface 211. When cross pin 172 is adjacent release region 211, the upper bar 79 can be lifted away from the vertical stub of elbow 72. Therefore, the cross pin 172 may have a resting position in the pin capture opening 198 generally adjacent capture region surface 210. In a user actuated position when cross pin 172 is adjacent release edge 211, the user can withdraw stem 192 from longitudinal stub 170 by lifting up bar 79. To lock cross pin 172 into cross pin capture slot 198, the user may release user actuatable surface 182 in a direction opposite arrow 182A, cross pin 172 ends up contacting opening edge surface 210 thereby locking the pin in the forward end of the capture region. A mirror of the lock and capture system shown in FIG. 24 is provided on the left side of elbow 74 shown in FIG. 24. Also, some elbows may only have a single longitudinal stub, such as the forward-most elbow and rearward-most elbow.

[0094] FIGS. 25 and 26 illustrate embodiments of an upper rack bar 79. Stem 192 may be a longitudinally extending plate extending form the terminal ends of the upper rack bar 79. Generally, upper bars 79 may be tubes and stem 192 is a singular extending plate. Stem 192 defines the open mouth 194, narrow throat 196, and cross pin capture slot 198. FIG. 25 shows elongated upper bar 79 having at terminal end 192 the pin capture opening 193 at left terminal end 190A and pin capture opening 193 at right side terminal end 190B. The pin capture openings 193 are complementary to the size and shape of cross pin 192. The cross pin is either biased forward or biased aft and the cross pin moves within the pin capture opening 193 and the cross pin slot 174.

[0095] Turning generally to FIGS. 27-39, embodiments of rail systems are shown and described which may include inter-bed components including, for instance, bed dividers and storage boxes. These inter-bed components may be included as part of an embodiment of a rail system, used with other components such as hoops 70 disclosed outside these figures.

[0096] Beginning with FIGS. 27 and 30, a rail system is illustrated including a truck bed divider and locker. FIG. 27 shows the locker top 222 in an open position and FIG. 30 shows locker top 222 in a closed position contacting and closing an interior truck bed space 6 with truck bed divider 224. In operation, when locker top 222 mates with bed divider 224, truck bed interior space 6 is segmented from truck bed divider space 19, and segregated space 6 is separately secured and locked. Therefore, third parties cannot gain access to locker box space 6 unless they have access codes or keys to open diagrammatically illustrated lock system 230.

[0097] FIG. 30 shows that locker top 222 may be attached via hinges 250 to cab side rail 26. As discussed earlier in connection with FIGS. 9A, 9B, the forward most stanchions 32 may have a fore end coupler on the forward most end of the elevated bar element of the stanchions. The stanchion elevated bar element may be elevated above the stanchion base platform by standposts as previously described. Additionally, FIG. 9A, 9B describe the cab side rail having, at its terminal ends, a corner rail end coupler that mates with the fore end couplers on each forward stanchion. As also explained in connection with earlier figures, stanchions 30, 32 are adopted to mount to left and right side rails in an elevated manner above truck bed sidewalls 12, 13.

[0098] FIG. 27 shows a laterally extending cross bed bar 225 which is spaced away from cab side rail 26 (FIG. 32) at a predetermined longitudinal distance. In the illustrated embodiment, clamp systems 226 are utilized to attach the terminal ends of the cross bed bar 225 to side rails 22, 24. The attachment mechanism may include one or more clamps described previously in connection with FIGS. 13 through 18. In one embodiment, the locker top could have a longitudinal span less than the height of the cab-side truck bed wall. If the cross bed bar was removed, the shortened lock top can be stored next to the cab-side truck bed wall. Some variation in longitudinal span can take into account the elevation of the cab-side rail.

[0099] Locker top 222 may have, along its forward edge region, one or more locker top hinges 250 as shown FIG. 30. The longitudinal span of locker top 222 may be substantially the same as the predetermined longitudinal distance between bed divider (bar 225 and panel 224) and the front cab side rail 26. One or more hinges 250 (FIG. 30) permit locker top 222 to swing from a vertically open top position shown in FIG. 27 to a closed and potentially locked horizontal position in FIG. 30. In a closed position, the locker top encloses interior truck bed space 6 which is defined by the truck bed sidewalls 12, 13, the fore end truck bed wall and the bed divider system 225, 224. A lock system 230 (diagrammatically illustrated) may be utilized by the user to lock locker top 222 to cross bed bar 225.

[0100] FIG. 28 shows an embodiment of cross bed bar 225 and certain bed divider panels which may be movably attached or may be fixed on the lower region of cross bed bar 225. The bed divider can have a single, fixed panel attached to the cross bed bar 225. In the illustrated embodiment of FIG. 28, the truck bed divider panel 224 has a stationary mid panel section 235. Mid panel section 235 may be fixed to the lower end regions or lower edge of cross bed bar 225. Additionally, two movable side panel sections 234, 236 may be provided. The side panel sections 234, 236 move in a guide (shown in FIG. 29) in the lower region of cross bed bar 225. Particularly in FIG. 28, movable side panel 226 may move as shown by arrow 237 and as illustrated by the dashed lines in the figure. In addition, FIG. 28 shows that a fixation element such as a lock system 230A may be utilized to lock the movable extending panels 234, 236 with respect to the stationary panel 235. In this manner, divided out truck bed space 6 (FIG. 27) is securable from intrusion by third parties because the panels are fixed together. Possible fixation elements may include screws, nut and bolt sets, set screws, pin locks, etc.

[0101] FIG. 29 shows an embodiment of the cross bed bar 225 having a cavity 240 along upper rail bar edge within which extends a depending lip 228 of locker top 222. The locker top 222 can be moved as shown by arrow 231 downward towards the cross bed bar such that the depending edge lip 228 of the locker top fits within cavity 240. A lock system 230 embodiment is illustrated which extends through depending edge 228 of the locker top and through a portion of the cross bed bar 225. Cross bed bar 225 may also have a depending structure 225A which forms guide channels 236A and 235A. Stationary panel section 235 may be mounted in a fixed manner in channel 235A. The side edge of panel 235 is shown in the figure. Movable side panel 236 may be movably mounted in guide channel 236A. Movable side panel 236 is illustrated in cross-section.

[0102] Embodiments of truck bed dividers may include a single movable panel utilized in conjunction with a single fixed panel, or may include one or more movable panels, or may include a stationary mid panel and two opposing movable panels as provided in the embodiment shown in FIG. 28. Also, a lower guide plate 235 may be mounted on the truck bed 12 floor such that some panels move both in the upper guide channels 236A (guide channel 235A for the stationary mid panel) and the lower guide plate. The fixed panel 235 may be fixed in both the upper and lower guides and, as such is supported at the top and bottom. The lower guide elements 235A support the bottom edges of all the panels. Plate element 235 may be attached to the floor of the truck bed. Depending front edge 228 of locker top 222 must be large enough to engage the lock system 230 and fit tight into the channel in the cross bed bar to prevent debris and water from intruding within segmented bed space 6.

[0103] FIG. 31 shows that locker top 222 has front edge 228 and depending side edges 228A which may exclude debris, dust and water from segmented truck bed space 6. The depth of edges 228, 228A should be greater than the distance between the elevated bar elements of the stanchions and the stanchion base platform. In this manner, a secured space may be provided in segmented truck bed region 6 by the truck bed divider and locker top. As previously discussed, the clamp systems 226 may be the same or substantially similar to the various clamps discussed above in connection with FIGS. 13-18. Other connections may be used. The movable panel sections 234, 236 are adopted to move within the guide channels 236A and vertical panel edges 236E abut truck sidewalls 12, 13. As discussed later, edge 236E (FIG. 28) may include rubber seals or plastic seals or other flexible elements to exclude debris, dust and water from the segmented truck space 6.

[0104] FIG. 32 shows a detail of the locker top hinge 250. Hinge 250 may include a rail sleeve 252 which has a passage 252A there through. The size of passage 252A may match or compliment the cross sectional dimension and shape of the cab side rail 26 (FIG. 30). The rail can be any defined shape or profile. Rail sleeve 252 may be a split sleeve and the sleeve halves may be attached to friction compress and mount on rail 26 in any reasonable manner such as by a bolt and nut, threaded passage way and threaded bolt. An attachment passageway 254 is shown in FIG. 32. Hinge 250 may have a depending stem 256 with a forward extending plate 259. Depending stem 256 may have a depending plate region 258 attached to the rail sleeve 252. Hinge 250 may also include a first hinge swing arm 260. The first hinge swing arm 260 is pivotally attached at point 260A to the depending stem 256. One end of the first swing arm 260 is attached to the depending stem 256. The other end of swing arm 260 is attached at pivot point 260B to the locker top forward edge region 261 shown in FIG. 31. Locker top hinge 250 has a second hinge swing arm 262. One end of the second hinge swing arm 262 is pivotally attached at pivot point 262A to an end of the forward extending plate 259 of depending stem 258. The other end of the second hinge swing arm 262 is pivotally attached at point 262B to a mid section of the first swing arm 260. It should be noted that with respect to the foregoing description of the locker top hinge, the term “forward extending” when taken in relationship to the pickup truck cabin, is actually a rearward extending plate. The forward end of the hinge may attach to the cab rail. The rearward end of the hinge may attach to the forward edge regions of the locker top. In other words, as shown in FIGS. 30 and 31, locker top hinge 250 may extend from a forward position on cab side rail 26 to a rearward position defined by depending stem 256 and rearwardly extending plate 259, and the first hinge swing arm 260 may extend rearwardly therefrom.

[0105] FIG. 33 diagrammatically illustrates a truck bed divider system that may have several similar components as described above in connection with the truck bed divider and locker top system shown and discussed in conjunction with FIGS. 27 and 30. For example, the truck bed divider 270 may include a laterally extending cross bed bar 274. The truck bed divider 270 can be used separately and independent of second truck bed divider 272. With respect to truck bed divider 270, cross bed bar 274 includes connectors at or proximate to its terminal ends to the left and right side rails 22, 24. The connectors can be one or more of the clamps shown and discussed earlier in connection with FIGS. 13-18.

[0106] Truck bed divider 270 may feature a lateral span substantially similar to the truck bed lateral span defined between left and right truck bed sidewalls 12, 13. With respect to truck bed divider 272, the bed divider panel 293 may span the entire truck bed lateral span. Truck bed divider panel 232 may be mounted in a fixed manner at the lower edge of laterally extending cross bed bar 278. In another embodiment, bed divider panel 293 can be a triple panel system as shown and discussed earlier in connection with FIG. 28. The bed divider panel 290 may also be constructed slightly differently than the bed divider panel solid piece 293 shown in FIG. 33 or the three piece bed divider panel discussed earlier in connection with FIG. 28.

[0107] With reference to FIG. 34, panel 290 may be designed to mate and couple to the side-step well in the truck bed. Divider panel 290 may have an upper fixed lateral panel 310 which may be fixed to the cross bed bar 274. Mounts 312 on the left and right side of cross bed bar 274 may operate to fix the upper lateral panel 310 to bar 274. Additional mounts 314 are also utilizable for stability. The lower edge 310A of the fixed upper panel 310 has a plurality of guides similar to the guides shown in connection with FIG. 29 and guides 236A, 235A on cross bed bar 225. In this manner, the bed divider 290 in FIG. 34 has a stationary lower mid panel section 316 and movable lower panel sections 318, which can adjust to the left and right of the lateral span for truck bed 19 (see FIG. 33) to accommodate the side-step wells in the truck bed. Additionally, the exposed side edges or ends 318B of movable panels 318 may include rubber, plastic or other compressible edge material 324 to seal bed divider panels 318 against the side-step wells 7 of pickup truck 10. Further, the exposed lower edge of the fixed upper panel 310 may include sealed element 326 of rubber, plastic, foam or other material to seal the bed divider 290 onto side-step wells 7 of pickup truck 10. Also, as discussed previously, the attachment mechanism for the cross bed bar is shown as clamp 276 in FIG. 34.

[0108] FIG. 35 shows a truck bed divider that can be positioned at an oblique angle with respect to the side walls 12, 13 of pickup truck 10, which is also to say that it may be positioned not orthogonal to the rear end of the truck. In the illustrated embodiment of FIG. 35, bed divider 410 may be attached via clamps or any other attachment mechanisms 412 to side rails 22, 24. Truck bed divider 410 is shown at an oblique angle with respect to sidewalls 12, 13 of pickup truck 10 where the distance 415 to the rear tailgate of the truck is smaller than rear distance 417. In this manner, the vehicle operator can obliquely adjust the truck bed dividers and trap and fix materials and items (such as barrels or canisters) against the tailgate of pickup truck 10 typically found at rear end 17 of the truck and the bed divider.

[0109] FIG. 36 illustrates an oblique rail clamp 412 utilized to provide the obliquely adjustable truck bed divider 410. Many of the features of clamp 412 are discussed earlier in connection with clamp 78. However, in FIG. 36, the oblique clamp 412 may include a smaller diameter interior rail passageway 433 which matches the cross dimensional size of rail 22, 24. The smaller diameter interior rail passageway 433 has a small longitudinal span compared to the balance of the longitudinal span of the clamp-rail passage. Oblique clamp 412 also defines in its interior, a larger cross sectional rail passage 431. In other words, small passage 433 matches the size of rail 22, 24 whereas large passage 431 is much larger than small rail passage 433. When oblique clamp 412 is mounted on rail 22, a space 435 is established between rail 22 and the interior surface of large rail passage 431.

[0110] Since the small rail passage 433 clamps onto rail 22 with a compression friction grip, the clamp 412 and the attached cross bed bar can be moved or swung with respect to the axial centerline of rail 22 thereby creating an angle in larger diameter space 435. The angled space permitted by oblique clamp 412 is defined by the size of radial size of space 435 immediately next to step up 435A at the small rail passage 433 and the longitudinal length 437 of the space 435 in the interior of oblique clamp 412. In other words, clamp 412 can be twisted such that the forward end 437A is adjacent to or contacts rail 22. In this manner, the cross bed bar 410 in FIG. 35 can be angled at an oblique angle with respect to rear end 17 of pickup truck 10.

[0111] FIG. 37 shows a different view of oblique clamp 412. The step surface 435A is shown between the smaller radial space 433 and the larger radial passage 431. The size differential 437 between these two radial passages 433, 431 is also illustrated in FIG. 37.

[0112] FIG. 38 illustrates a clamp 462 with split clamp jaw segments which may be threadably attached together. Clamp 462 has clamp jaw members 462A and 462B. Clamp jaw members 462A and 462B may be attached together via threaded bolt or screw 464 which connects with threaded passageway 465 or a nut in the passageway. In this manner, there may be no lever and no release lever as shown in FIGS. 13-14. Split clamp 462 can be used on the cross bed bars rather than the lever release clamp shown in FIG. 27, 30 or 35. Additionally, FIG. 38 optionally shows a small radial passage 431 which may convert the split clamp into the oblique clamp. With a small radial rail passage 431, the clamp is an oblique clamp. If small radial rail passage 431 is eliminated, then clamp 462 is a common clamp described earlier.

[0113] FIG. 39 illustrates an embodiment of crossover box 510 for a pickup truck bed. Cross over box 510 may have a box lid 512. Crossover box 510 may be mounted on cross bed bars (not shown). The cross bed bars may be attached via clamps 514 to the left and right rail 22, 24. In this manner, the rail system can easily accommodate a crossover box 510.

[0114] FIGS. 40-44 illustrate embodiments of elevated rails 600 as may be included in embodiments of a rail system. Generally, each set of elevated rails 600 may include a top rail 610 and a bottom rail 612 substantially parallel to top rail 610. When installed as part of a rail system, the elevated rails 600 may elongate along the truck bed 12 above, for instance, left and right side walls. A bent rail end 620 may be provided proximate to a forward end (as illustrated in FIG. 40), proximate to rearward end of the vehicle, or on both ends. Bent rail ends 620 join top and bottom rails 610, 612 thereby creating a particularly useful handle for the vehicle operator to grasp as he or she is maneuvering the rail system.

[0115] Elevated rails 600 may be secured into place through insertion of rods 80 from one or more elbows 74 of one or more hoops 70 into rod sleeves 611, 614, 616, 618. Different embodiments of rod sleeves 611, 614, 616, 618 are disclosed herein. A securing collars 624 is one such attachment mechanism for securing a rod sleeve with a rod 80. Securing collars may be connected at a base of a rod sleeve 611, 614, 616, 618 and may be tightened by a tightening mechanism in order to secure the rod 80 within the sleeve. In this respect, collar 624 may be comprised of two conforming collar halves 626, each having a collar aperture provided on a protruding collar tab 628. A fastener 627 such as a nut and bolt may be provided through collar aperture 627 and tightened in order to press-fit each collar half 626 together, thereby securing rod 80 from removal from sleeve 611, 614, 616, 618. As illustrated, rod 80 may protrude from the top of the sleeve as inserted, or alternatively the sleeve may fully encompass the distal end of the inserted rod 80. It should be appreciated that elevated rails 600 may be designed for accommodating rods from three hoops 70, and yet function perfectly well if only two hoops 70 are included as part of the active embodiment of the rail system.

[0116] Embodiments of rail system disclosed herein should be not limited to embodiments where components of the rail system only extend upwards in an elevated direction. For instance, stanchions 30 may project from the side of a vehicle thereby contemplating an embodiment where side rails 22, 24 run along the side of vehicle 10. As evidenced by this contemplated embodiment, the term “elevated” and similar terms used herein should not be limited to components having a greater distance from the earth than a related non-elevated component. Rather, the term “elevated” and similar terms should be recognized to generally mean two components at a distance, or perhaps a variable distance, between one another, including a possible horizontal or angled distance.

[0117] The descriptions set forth above are meant to be illustrative and not limiting. Various modifications of the invention, in addition to those described herein, will be apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the concepts described herein. The disclosures of each patent, patent application and publication cited or described in this document are hereby incorporated herein by reference, in their entireties.

[0118] The foregoing description of possible implementations consistent with the present disclosure does not represent a comprehensive list of all such implementations or all variations of the implementations described. The description of some implementation should not be construed as an intention to exclude other implementations. For example, artisans will understand how to implement the invention in many other ways, using equivalents and alternatives that do not depart from the scope of the invention. Moreover, unless indicated to the contrary in the preceding description, none of the components described in the implementations are essential to the invention. It is thus intended that the embodiments disclosed in the specification be considered as illustrative, with a true scope and spirit of the invention being indicated by the following claims
