2. Description of the Prior Art
DiSimone U.S. Pat. No. 4,811,875, issued to one of the present inventors on Mar. 14, 1989, discloses a portable automotive bench comprising a center section and two opposed drawers slidably received within the center section. Support members mounted on the opposed lateral ends of the two drawers rest on opposed lateral edges of an engine compartment of a motor vehicle or the like. The center section is movable from side to side to allow access to the drawers. The present invention represents an improvement on the portable automotive bench disclosed in the DiSimone patent.
Objects and Summary of the Invention
In is an object of the present invention to improve upon the automotive bench disclosed in DiSimone U.S. Pat. No. 4,811,875 while achieving all of the useful objects and advantages of that invention.
More particularly, it is an object of the present invention to provide a mechanic's tool tray and support assembly manufacturable less expensively and providing additional flexibility in use with respect to that disclosed in DiSimone U.S. Pat. No. 4,811,875.
More specifically, it is an object of the present invention to provide a mechanic's tool tray and support assembly which can be disassembled into its component parts very readily, for storage under lock and key in an conventional mechanic's tool box having storage compartments of standard sizes, to prevent theft of the tool tray of the invention.
It is a further object of the invention to provide tool trays for being supported by a support assembly resting on opposed edges of an engine compartment of a motor vehicle or the like, the trays also fitting within storage compartments of standard sizes of a standard mechanic's tool chest, so that a mechanic can store the tools, parts, and supplies used to perform certain standard tasks in one or more of the trays, and simply take those trays containing the tools, parts, and supplies needed for performance of any specific task from his tool chest and place those trays on the tool tray support assembly of the invention in preparation for that task.
It is a further object of the invention to provide a tool tray support assembly as described above and also comprising a work shelf and a work light, to provide a convenient flat surface for the mechanic to store parts and tools and to provide illumination to render his work more convenient.
It is a further object of the invention to provide a tool tray support structure adapted to hang from a standard vehicle service lift to enable the mechanic to conveniently use the tool trays and support assembly of the invention when working beneath a vehicle.
It is a further object of the invention to provide a tool tray support assembly whereby individual tool trays can be readily supported by a roll-around stool, so that a mechanic may obtain maximum versatility in use of tool trays purchased for use with the tool tray support assembly of the present invention.
These and other aspects, objects and advantages of the present invention will be apparent to those of skill in the art as the discussion of the invention below proceeds.
The objects of the invention mentioned above are satisfied by the tool trays and support assembly of the present invention. The support assembly comprises a center member including a work shelf, two laterally extensible support members each comprising two parallel rails slidably received by the center member, and two end support assemblies attachable to laterally opposed distal ends of the laterally extensible support members. The support members slide within channels in the center member so as to be adjustable to suit the width of the engine compartments of various motor vehicles. The center member comprises locking levers to secure the extensible support members at desired positions. The end support members allow adjustment of the angle formed between foot members resting upon the opposed lateral edges of the engine compartment with respect to the support members and center member, so that the tool tray of the invention is useful with vehicles wherein the edges of the engine compartment are not horizontal.
In order to render the tool tray support assembly of the invention convenient in use, and so that all components fit conveniently within the drawers of a normal mechanic's tool chest, the end support assemblies are made readily removable from the ends of the laterally extensible support members. All components of the end support assemblies remain attached to one another when removed from the support members, so that the mechanic is not obliged to search for small parts in order to assemble the tool tray of the invention.
The end support assemblies each comprise a keying member comprising a slot on one side receiving the end portions of the laterally extendable support members, and radial keys on the other side thereof. The radial keys on the keying members are drawn axially into engagement with mating radial keys formed on end supports also comprising the feet resting on the edges of the engine compartment. Hand screws are provided for axially engaging the end supports, the lateral support members and the keying members.
The tool trays comprise generally rectangular box members having overhanging portions extending along their longitudinal edges. The overhanging portions rest on the opposed parallel rails of the lateral support members, while a central box portion fits between the rails of the support members. The dimensions of the trays are such that they fit within the standard drawers of standard mechanic's tool chests. In this way a mechanic who customarily performs the same set of tasks repetitively can collect whatever tools and parts commonly are required for each particular task in one or more of the standard tool trays and select those trays from his tool box when that task is required to be performed once again. This provides very convenient tool organization. The tool trays may comprise or be fitted with tool organizers to conveniently retain particular sets of tools, such as socket sets. The same tool trays may also be supported beneath a roll-around stool for convenient working in confined spaces.
Hanging end supports may also be provided for supporting the tool tray support assembly beneath a vehicle service lift or the like. The hanging end supports interfit with the ends of the lateral support members in essentially the same manner as the end support assemblies provided to rest on opposed lateral edges of an engine compartment of a motor vehicle.
The invention will be better understood if reference is made to the accompanying drawings.

Description of the Preferred Embodiments
Referring now to FIGS. 1, 2 and 3, the tool tray support assembly of the invention comprises a center member 10, two identical opposite laterally extensible support members 12 and 14, and two identical end support assemblies 16 and 18. The center support member 10 comprises a work surface 22, essentially a plain rectangular panel of a durable plastic material, and two identical sections 24 and 26 of a continuous aluminum extrusion. As shown in FIG. 2, the sections 24 and 26 of the aluminum extrusion each comprise two longitudinally extending channels for receiving parallel rails 12a and 12b of the first lateral support member 12 and parallel rails 14a and 14b of the second lateral support member 14. The lateral support members 12 and 14 are formed by bending lengths of stock material of continuous cross-section, e.g. plated rectangular section steel tubing, into U-shapes. Thus, for example, support member 12 comprises parallel rails 12a and 12b and end section 12c. As indicated, the rails are received by the sections 24 and 26 of the extrusion in interdigitated fashion; that is, the four rails 12a, 12b, 14a and 14b all lie in a plane parallel to the work surface 22, and the parallel rails of each of the lateral support members are spaced equally from one another. In this way, the lateral support members are identical, simplifying manufacturing and reducing cost. Alternatively, the rails could telescope within one another, or the rails of one support member could be disposed beneath the other; either alternative would be more costly.
In order that the center of gravity of the overall assembly is centered, the end supports 16 and 18 are attached to the lateral support members 12 and 14 off center with respect to the rails of the respective support members. Thus, as seen in FIG. 3, lateral support member 12 is displaced to one side of the center member while lateral support member 14 is displaced to the other side; however, the end supports 16 and 18 lie on the center line of overall assembly. In this way the overall assembly is well balanced and stable in use. Either end support may be assembled to either support member, simplifying assembly of the tool tray support assembly prior to use.
As further shown in FIG. 2, the extrusion from which sections 24 and 26 are taken also comprises a C-shaped upper member 32 defining a channel receiving the lateral edges of the work shelf 22. An accessory block 34 is formed to comprise a hook 34a fitting over the C-shaped member 32 of the extrusion, to support the block 34 thereon. The accessory block 34 may include a second hook 34b fitting over a tab 50 formed on the lower surface of the extrusion. The accessory block 34 may comprise a small shelf having holes therein for receiving small tools or the like as indicated in phantom at 35 in FIG. 2. A different version 37 of the accessory block shown in FIG. 9 may include a small open parts box 39. Desirably the corner at which the bottom of the parts box 39 meets its front surface is curved as indicated at 39a; this makes it easy for the mechanic to reach into the box 39 and scoop small parts out. A magnet 38 may be attached to the front of the box 39 for convenience in storing small ferrous tools.
Returning to the discussion of FIG. 1, first and second tool trays 40 and 42 are shown. Tool trays 40 and 42 each are formed so that their ends are generally of T-configuration, that is, so that trays 40 and 42 comprise overhanging opposed lateral portions 43 resting on the rails 12a and 12b, and depressed center portions 44 resting between the rails 12a and 12b. In a preferred embodiment these tool trays 40 and 42 are molded integrally of a durable plastic material, and are sized such that they fit efficiently within the standard drawers of a standard mechanic's tool box. Typically this will require that their depth be no more than two inches. These tool trays may be made in a number of different lengths and may have various internal dividers for convenient storage of various collections of tools, parts and the like. The tool trays may comprise or be fitted with tool organizers for conveniently receiving and retaining various sets of tools such as socket sets, sets of screwdrivers, and the like.
Referring now to FIG. 2, it will also be observed that the extrusion from which sections 24 and 26 are taken comprises a lower tab portion 50 on its under surface for receiving a clear plastic window 52. Within the space created between the work surface 22 and the window 52 may be mounted one or more fluorescent lamps 54 or other source of illumination; these may be mounted on the window 52 as shown, or mounted to the underside of the work surface, as convenient. The window 52 protects the lamps 54 from damage in use and in storage.
It will also be apparent from FIG. 2 that the work shelf 22 may be permanently joined to the sections 24 and 26 of the extrusion by rivets or screws indicated generally at 56.
As seen in FIG. 1, the end support assemblies 16 and 18 each comprise feet 30 for being received on the opposed lateral edges 60 of an engine compartment of a motor vehicle or the like. Of course, the tool tray support assembly of the invention is also useful for other applications. In order to avoid marring the surface finish of the vehicle, resilient rubber pads 62 may be provided beneath the feet 30. Magnets 64 may also be provided to ensure stable resting of the end supports 16 and 18 on the opposed lateral edges of the engine compartment of the vehicle. Where the vehicle is of nonferrous material a security strap (not shown) having a hook or suction cups at one end may be provided to secure the end support members 16 and 18 to the vehicle. To facilitate this possibility, slots 66 are formed in end supports 16 and 18 to receive a security strap, elastic cord or the like.
Referring now to FIG. 3, stop screws 68 are provided at the lateral ends of one of the rails of each of the two lateral support members 12 and 14. These stop screws 68 are adapted to abut stop members 70 mounted in sections 24 and 26 of the extrusion adjacent the channels in which the rails ride. Thus the stop screws 68 limit the excursion of the support members 12 and 14 with respect to the center section 10, so that the support members 12 and 14 remain assembled to the center section 10, further simplifying the use of the system of the invention. If necessary the stops 70 can be removed to allow removal of the support members 12 and 14 from the center section 10.
FIG. 4 details the structure of the locking lever assembly provided to enable the mechanic to lock the support member 12 in any desired position with respect to the center member 10. A similar assembly is provided with respect to support member 14, as seen in FIG. 3. The locking lever assembly comprises a lever 72 pivoted on a pivot member 74 fixed in a bore in the respective section 26 of the extrusion. As shown the locking lever 72 comprises a cammed surface 76 to urge the corresponding rail 12b into engagement with the inner surface 26a of the corresponding section 26 of the extrusion. A generally U-shaped anti-friction member 78, formed of a "slippery" plastic such as molybdenum disulfide filled nylon, may be provided between the cammed surface 76 and the rail 12b, so that when the locking lever is disengaged by rotating it counterclockwise (as indicated by the arrow 79 in FIG. 4), the rail 12b can slide freely within the channel of the extrusion 26. The pivot member 74 retains anti-friction member 78 in proper relation to the locking lever 72.
FIGS. 5 and 6 provide details of the interconnection of the end support assembly 18 with the respective support member 12. An identical connection is formed between end support assembly 16 and support member 14. As noted, the end supports are interchangeable with respect to the support members. The end support assembly 18 includes a key member 80 formed to include a recess 80a for receiving end section 12c of the support member 12. Thus the support member 12 is precluded from rotation with respect to the key member 80. The key member 80 also comprises a plurality of radial keys 80b molded on the opposite surface thereof. Keys 80b interfit with mating radial keys 82 formed on a molded upright 84. Thus when the key member 80 is drawn axially into engagement with the upright 84, the keys 80b and 82 engage, preventing relative rotation of the key member 80 with respect to the upright 84. The upright 84 is also molded to include a vertical spacing portion 85 and the foot 30, as shown in FIG. 1. The foot 30 is separated by a few inches from the mounting structure illustrated in FIG. 5 by the spacing portion 85.
The radial keys 80b on key member 80 are drawn into engagement with the keys 82 on the end support 18, and the end section 12c of the support member 12 is affixed to the upright 84, by a threaded hand screw 86. One end of hand screw 86 is permanently joined to a knob 88, while the other end of the hand screw 86 is threaded into a captive nut 90 typically spot-welded to the end portion 12c of the support member 12. When the mechanic desires to remove the end support 18 assembly from the support member 12 he simply turns the knob 88 counterclockwise, unscrewing the hand screw 86 from the captive nut 90. The key member 80, knob 88, and hand screw 86 are retained on the end support 84 by a spring clip 92 received in a groove in the threaded hand screw 86. In this way the components of the end support assembly 18 do not become separated from one another in the mechanic's tool box and can be readily attached when desired.
The mating radial keys 82 and 80b allow the relative orientation of the end support 84 and the support member 12 to be varied over a substantial range of angles. The extent of this range is controlled by the interfitting of a peg 96 formed on the end support 84 within a recess 80c formed on the key member 80. Thus the angular extent of the recess 80c controls the maximum amount of angular adjustment of the position of the support member 12 possible with respect to the upright 84.
In order to facilitate angular adjustments, a "wave" spring washer 98 is retained between the mating keys 80b and 82. Thus, when the knob 88 is turned counterclockwise to release axial engagement of the teeth, the wave washer 98 positively urges the teeth out of engagement with one another, simplifying angular adjustment of the relevant positions of the support member 12 with respect to the upright 84 of the end support assembly 18.
In the preferred embodiment, the key member 80 is molded to comprise the radial keys 80b, the arcuate recess 80c and the recess 80a for receiving the end section 12c of the support member 12. The upright 84 is similarly molded to comprise the keys 82 and the feet 30 (FIG. 1) as well as peg 96. The knob 88 may be turned of metal or molded of plastic; in either event it preferably comprises a shoulder portion 88a, of similar radial extent as the keys 80b and 82, further providing durability and reliability to the structure.
The tool tray support assembly of the invention may also be arranged to hang beneath an automotive service lift 100 as shown in FIG. 7. The end support assemblies 16 and 18 are removed and replaced with a second set of identical end supports, one being indicated at 102. The end support 102 comprises a knob 104 connected to a threaded member threaded into captive nut 90 welded to lateral support member 12 by which the end support structure detailed in FIGS. 5 and 6 is attached. However, in this case there is no need to provide angular adjustment of the plane of the tool tray 22. Accordingly, the end support 102 comprises key means 106 receiving the end section 12c of the support member 12 to provide a stable working platform.
The upper portion of the end support 102 comprises two transversely extending pegs 108. Pegs 108 are received in recesses 110 in a circular disk member 112, while a planar portion of the vertical support member 102 fits within a transverse slot 114 extending partially across disk member 112. As indicated at 116, the end support 102 can be assembled to the disk member 112 in a foolproof and stable manner simply by inserting the end support 102 into the transverse slot 114, so that the pegs 108 fit into the recesses 110. This assembly method requires no tools. As shown, the disk member 112 comprises a cylindrical lower portion 112a capped by a radial flange 112b. The cylindrical portion 112a fits within a circular aperture 116 in a planar lower portion 120 of a clip 118 adapted to fit over horizontal member 124 of a standard automotive lift 100. The flange 112b then rests on the planar lower portion 120 of the clip 118. A gap 122 in the lower portion 120 of the clip 118 allows the vertical support member 102 to pass through the clip 118. As the circular disk 112 is supported within the circular aperture 116 in the planar portion 120 of the clip 118, the angular orientation of the tool tray support assembly of the invention may vary with respect to the horizontal member 124 of the lift 100.
In use the clip 118 will typically remain permanently on the horizontal member 124 of the automotive lift 100. The design of the clip members 118 will vary with respect to the design of the horizontal member 124 of the lift 100. The circular disk 112 may also be permanently assembled to the clip 118.
FIG. 8 shows a rolling stool comprising casters 130, a seat 132, and one or more support members 134 and 136 for supporting tool trays according to the present invention, as indicated at 138 and 140. Kits of hardware for conveniently adapting various preexisting stools to thus receive tool trays according to the invention may be sold separately. In this way the tool trays of the invention are provided with additional flexibility, adding to their utility to mechanics and other service personnel.
A mechanic will typically store the tools and parts needed to complete a particular job in one or more of the tool trays according to the invention. When he is called upon to perform that particular job he will select those tool trays and will assemble them together with the appropriate support structure. In most cases this will involve the support structure shown in FIGS. 1 and 3, that is, employing end support assemblies 16 and 18 to support the tool tray support structure between opposed edges 60 of an engine compartment of a motor vehicle or the like. In other cases he may desire to support the tool tray support assembly according to the invention from a vehicle lift as shown in FIG. 7, or he may use one of the tool trays in conjunction with a stool as shown in FIG. 8. Assuming the first case, he adjusts the tool tray to its desired lateral extent using locking levers 72, and adjusts the relative angular orientation of the plane of the work surface 22 with respect to the lateral edges of the automobile 60 using the angular adjustment feature provided by the end support assemblies 16 and 18, as detailed in connection with FIGS. 5 and 6. He then selects the tool tray(s) containing the appropriate tools, parts, and supplies, and disposes them between the opposed parallel rails of the support member 12 and 14, and may employ the work surface 22, lamps 54 and the like as desired.
When the job is completed the mechanic may readily remove the tool trays 42 and store them in conventionally sized drawers of a tool box, and may then remove the end support assemblies 16 and 18 simply by loosening knobs 88. As noted, the end support assemblies remain assembled, so that no loose components are lost. Finally, he may then loosen locking levers 72, slide the support members 12 and 14 into the center section 10 until stop screws 68 abut stops 70, and store the entire assembly away, again in a standard tool box. In this way, the entire tool tray support assembly and the tool trays can be conveniently stored under lock and key.
It will be apparent to those of skill in the art that while a preferred embodiment of the invention has been disclosed in detail, numerous other modifications and improvements can be made thereon.
For example, numerous different sorts of accessory blocks as indicated generally at 34 and 37 may be provided to fit on the sections 24 and 26 of the extrusion on either side of the center section. Additional illumination devices may be added; a rack for holding a service manual open might conveniently be added. The tool trays may include or be fitted with tool organizers such as plastic receptacles sized to receive the members of standard tool sets, such as socket sets or screwdriver sets; alternatively, the members of a socket set may be retained on plastic studs or metal clips fitting the standard square recesses by which the sockets are affixed to a ratchet wrench for use. Other modifications similarly will occur to those of skill in the art. Therefore the above description of the invention, while disclosing the best mode of practice thereof known to the inventors at the time of filing of this application, should not be taken as a limitation on the scope of the invention but only as exemplary thereof; the scope of the invention is to be measured only by the following claims.
