[0002] 1. Field of the Invention

[0003] The present invention relates generally to the field of automobile and truck accessories. More specifically the present invention relates to a gate supporting assembly for use in combination with a truck bed behind a cab of a truck, the truck bed having a gate, the gate supporting assembly holding the gate in a partially raised position to retain cargo while minimizing drag, increasing fuel efficiency, providing air foil traction enhancement while leaving the rear bumper exposed and functional. The gate supporting assembly includes a first cable fastened to cable connectors which engage the bed and gate to hold the gate in the partially raised position when at full extension and preferably includes a conventional second cable fastened to cable connectors which engage the bed and gate to hold the gate in a substantially horizontal position, the second cable preferably being connected to the first cable.

[0004] 2. Description of the Prior Art

[0005] There have long been connecting members in the form of linkages and cables interconnecting truck bed side walls and lateral ends of bed gates for supporting the gate in an open, horizontal position. These connecting linkages and cables, sometimes referred to as tail gate lift cables, have served their intended purposes well, but have failed to adequately meet a several important needs of many truck owners.

[0006] The purpose of these prior connecting members is to support the gate in an open position during loading and unloading of the bed. Yet many truck owners have discovered that closed gates trap wind and create substantial drag when the truck is moving, greatly reducing fuel efficiency. As a result, many truck owners drive with their gates in the open position to eliminate this drag, but at the same time risk loss of any cargo in the bed and risk substantial liability during rear end accidents in which the open gate rides over the hood of a closed vehicle and into a vehicle occupant or into the chest of a motorcyclist sliding into the rear of the truck.

[0007] What is needed is a gate supporting assembly for positioning the gate in a position which angles back from vertical to minimize wind drag, and yet at the same time angles upwardly from horizontal to retain bed cargo and to better expose the rear truck bumper to receive direct impact.

[0008] It is thus an object of the present invention to provide a gate supporting assembly which interconnects a truck bed side wall and a pivoting bed gate to position the gate at an angle between horizontal and vertical and thus which permits the gate to retain bed cargo.

[0009] It is another object of the present invention to provide such a gate supporting assembly which lowers the gate sufficiently to substantially reduce wind drag when the truck is moving.

[0010] It is still another object of the present invention to provide such a gate supporting assembly which exposes the rear truck bumper for contact during a collision.

[0011] It is finally an object of the present invention to provide such a gate supporting assembly which deflects passing wind when the truck is moving in such a way that the wind creates a downward force at the rear of the truck to increase rear wheel traction.

[0012] The present invention accomplishes the above-stated objectives, as well as others, as may be determined by a fair reading and interpretation of the entire specification.

[0027] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

[0028] Reference is now made to the drawings, wherein like characteristics and features of the present invention shown in the various FIGURES are designated by the same reference numerals.

[0029] Referring to FIGS. 1-7, a gate supporting assembly 10 is disclosed for use in combination with a truck bed B behind a cab of a truck, the truck bed B having agate G, for holding the gate G in a partially raised position to retain cargo while minimizing drag, increasing fuel efficiency, and providing air foil enhancement of rear truck tire traction while leaving the truck rear bumper exposed and functional.

[0030] The truck bed B is understood to include a bed bottom wall B1, a bed forward wall (not shown) defined by the rear surface of the cab, bottom wall lateral ends, a bottom wall forward end and a bottom wall rearward end; two opposing and spaced apart bed side walls B3 extending upwardly from and substantially along the bottom wall lateral ends, each bed side wall B3 having a side wall rearward end with a bed connector BC; and the bed gate G pivotally secured to the bed B at the bottom wall B1 rearward end to pivot upwardly to meet the bed side walls B3 and thereby close the bed B and to pivot downwardly to become substantially horizontal and contiguous with the bed bottom wall B1 and thereby open the bed B, the gate G having two opposing gate lateral ends, each gate lateral end having a gate connector GC. See FIGS. 1 and 2.

[0031] The gate supporting assembly 10 preferably includes a first cable 20 fastened to a primary cable connector 30 for connecting to one of the bed connectors BC and fastened to a secondary cable connector 40 for connecting to one of the gate connectors GC, the spacing between the primary cable connector 30 and the secondary cable connector 50 being such that the when the first cable 20 is at full extension the gate G is oriented at an angle substantially midway between horizontal and vertical, preferably at 40 to 45 degrees from horizontal. See FIGS. 3, 1 and 2. The assembly 10 preferably additionally includes a second cable 60 fastened to the primary cable connector 30, once again for connecting to one of the bed connectors BC, and fastened to a tertiary cable connector 50 for connecting to one of the bed connectors BC, the spacing between the primary cable connector 30 and the tertiary cable connector 50 being such that the when the second cable 60 is at full extension the gate G is substantially horizontal. Left side and right side versions of gate supporting assembly 10 preferably are provided which are essentially mirror images of each other. A version of gate supporting assembly 10 having linkages in place of cables 20 and 60 is contemplated.

[0032] A cable retaining means 90 in the form of a cable retaining band preferably is provided and encircles first and second cables 20 and 60, respectively, a distance from primary cable connector 30. See FIG. 3. As a result, when one cable 20 or 60 is in use at a given moment the cable 60 or 20 not in use is retained against lateral movement in close proximity to the cable 20 or 60 in use so that the cable not in use does not fall between a bed side wall B3 and the gate G and obstruct the gate G pivoting movement.

[0033] The primary cable connector 30 preferably is of well known construction and connects to a gate connector GC, the primary cable connector 30 including a fastener plate 32 having a plate fastener bore 34 and a fastener 36 having a fastener shank rotatably passing through the plate fastener bore 34 and having shank ends, the fastener 36 having a fastener head extending radially from a shank end which abuts the fastener plate 32 around the fastener bore 34. See FIGS. 3, 4 and 7. A plate stem portion 38 preferably extends radially from the fastener plate 32, and a cable anchor 80 in the form of a sheet of metal is wrapped around and compressed against the plate stem portion 38 and the first and second cables 20 and 60 to an extent that an extremely high friction grip is created which retains the cables 20 and 60 and the plate stem portion 38 when either cable is in tension supporting the bed gate G.

[0034] The bed connector BC preferably is of well known construction, including a cylindrical bed connector shank BC1 protruding laterally from the rearward end of each bed side wall B3 toward the opposing bed side wall B3. See FIG. 6. The shank BC1 has a bed connector head BC2 spaced apart from the bed side wall B3 to which the shank BC1 is attached and extending radially outward from the bed connector shank BC1, and has a bed side wall connection structure BC3. The bed side wall connection structure BC3 preferably includes a connection plate with a plate fastener hole and a plate fastener, which preferably is a machine screw.

[0035] Each of the secondary and tertiary cable connectors 40 and 50, respectively, preferably is also of well known construction, including a metal or plastic connector loop 72 having a loop narrower end 72asized to pass the bed connector shank BC1 but not to pass the bed connector head BC2, and a loop wider end 72bextending rearwardly. of the loop narrower end 72aand sized to pass the bed connector head BC2, so that the bed connector head BC2 can be passed through the loop wider end 72b,and then the connector loop 72 can be slid rearwardly so that the loop narrower end 72afits around the connector shank BC1 so that the connector loop 72 cannot slide over the connector head BC2 and off the bed connector BC. See FIGS. 5 and 6. A leaf retainer spring 74 preferably extends radially into the loop wider end 72bto abut a bed connector head BC2 and thus prevent the bed connector head BC2 from fully entering the loop wider end 72bunless the leaf retaining spring 74 is manually deflected. A loop stem portion 78 preferably extends radially from the connector loop 72, and another cable anchor 80 is wrapped around and compressed against the loop stem portion 78 and the first or second cable 20 or 60 to an extent that an extremely high friction grip is created which retains the given cable 20 or 60 and the loop stem 78 when the cable is placed in tension supporting the bed gate G.

[0036] An inventive and important addition to conventional secondary and tertiary cable connectors 40 and 50 is a spring gripping knob 76 fastened to the leaf retainer spring 74 toward but spaced apart from the leaf spring 74 free end. Since leaf retainer spring 74 must be manually deflected to release cable connectors 40 and 50 from a bed connector BC so that the user can switch from use of cable 20 to cable 60 and back again, the provision of spring gripping knob 76 makes the use of gate supporting assembly 10 far more practical. A leaf spring fastener bore is provided in leaf spring 75. Spring gripping knob 76 has an knob axial bore, and a screw or pop rivet 76ais inserted through the knob axial bore and through the leaf spring fastener bore.

[0037] While first and second cables 20 and 60 are preferred, alternative and equivalent interconnection structures are contemplated, including chains, linkages, brackets and hydraulic pistons and cylinders. The term “interconnection structure” is understood to be a more general term for primary, secondary and tertiary cable connectors.

[0038] While the invention has been described, disclosed, illustrated and shown in various terms or certain embodiments or modifications which it has assumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
