BACKGROUND OF THE INVENTION
1. Field of the Invention
Generally, the invention relates to a workroom storage system for organizing the tools and supplies found in workrooms, especially garages. More specifically, the invention relates to a space-efficient workroom storage system providing both wall mounted storage and cabinet storage, with a combination of slotwall panels, cabinets removably mounted to the slotwall panel, and a workbench in combination with mobile storage cabinets that are stowable beneath the workbench.
2. Description of the Related Art
There has long been a need for organized storage in workrooms, whether the workroom is a dedicated workshop, a garage, or any other room, since workrooms by their very nature tend to house many types of tools and equipment, along with general supplies and supplies for the tools and equipment. Past solutions to providing organized storage in workrooms were based on the operator selecting unrelated organization systems and combining them as operator saw fit, without an integrated system. The organization systems often reflected a hodgepodge of non-integrated solutions, such as fixed wall cabinets, pegboards, and work benches with internal storage, which collectively did not provide a space-efficient solution. That is, the resulting combination of components comprising the operator-selected organization system, often consumed more space in the workroom than what was necessary, which limited the amount of storage and/or work area in the workroom. Therefore, there is still a need for a space-efficient, integrated workroom organization system that helps the operator maximize both the storage of tools and supplies and the useful area of the workroom.
SUMMARY OF THE INVENTION
The invention provides a unique solution to the need for space-efficient, organized storage for a workroom via a workroom organization system comprising at least one slotwall panel in combination with a wall-mounted cabinet and floor supported workbench with at least one nesting mobile storage cabinet. The slotwall panel has multiple slots for receiving mounting brackets to mount the workroom items to the wall. At least one wall-mounted storage cabinet is provided and includes mounting brackets for removably mounting the at least one wall-mounted storage cabinet to the slots of the slotwall panel. The workbench comprises a work surface and multiple legs extending from the work surface to support the work surface above a floor and define a workbench recess beneath the work surface. The mobile storage cabinet has a top surface located at a height such that the at least one mobile storage cabinet can be received within the workbench recess with the top surface underlying the work surface. Wheels extend from the mobile storage cabinet to support the mobile storage cabinet on the floor to ease the movement of the mobile storage cabinet into and out of the workbench recess.
The workroom organization system enables a user to mount workroom items on the slotwall panel and arrange the at least one wall-mounted storage cabinet, workbench and at least one mobile storage cabinet within the workroom in a manner most space-efficient for a particular workroom. The system also enables the easy relocation of the workroom items and rearrangement of the wall-mounted storage cabinet, workbench, and mobile storage cabinet as needed over time as the quantity and mix of workroom items changes. Thus, the operator is provided with a space-efficient and flexible storage system.
The mobile storage cabinet has many different configurations. It can comprise a general storage cabinet, a drawer storage cabinet, or a refrigerated cabinet, for example. The system can accommodate multiple mobile storage cabinets positioned within the workbench recess and which can be of any mix of the exemplary mobile storage cabinets. The top surface of the mobile storage cabinet becomes an auxiliary work surface when the mobile storage cabinet is removed from the workbench storage recess.
Either or both of the work surface and the top surface can be made from wood. The wood can comprise multiple parallel strips of wood. A preferred wood is maple.
The workbench can further comprise a stringer connecting the multiple legs of the workbench to stiffen the support of the work surface. The stringer is preferably located toward a rear edge of the work surface to increase the volume of the workbench recess.
The multiple legs can be arranged in pairs, with each pair having a front leg and a rear leg, with the stringer extending between the rear legs. A cross member connecting both the front and rear leg for each pair of legs can be provided for additional stiffening.
The wheels supporting the mobile storage cabinet can include caster wheels to ease the storage and withdrawal of the mobile storage cabinet from the workbench recess.
The workbench can further comprise a power strip having multiple electrical power outlets. Preferably, the power strip is located at a rear edge of the work surface.
Height-adjustable feet can be added to the legs to permit the leveling of the work surface. The height-adjustable feet can comprise a foot plate and a threaded stud extending from the foot plate, and the corresponding leg has a threaded opening complementary to the threaded stud, such that the rotation of the foot will move the foot relative to the leg to adjust the height of the work surface.

DESCRIPTION OF THE INVENTION
In accordance with the present invention, a slotwall storage system incorporating a slotwall panel 10 having a plurality of generally “T” shaped slots 11 forming a plurality of generally “T” shaped slats 12 is provided with a hanger bracket for mounting a device on the slotwall panel. The slotwall panel can be formed of extruded polyvinyl chloride material. Co-pending U.S. patent application Ser. No. 10/747,421, discloses one such material, which patent application is incorporated by reference. The slotwall storage system according to the present invention can be used in a residential garage to provide storage for outdoor tools and equipment. A variety of storage options can be provided as will be described below. The slotwall storage system can also be used in a workroom or workshop, or in commercial and industrial locations. The slotwall storage system can be used in conjunction with a Modular Workbench System as disclosed in co-pending U.S. patent application Ser. No. 10/334,078, which application is incorporated by reference, and the disclosure of which is copied into this application as FIGS. 19–27 and the corresponding description. The workroom storage system can be used in conjunction with the Workroom Storage System disclosed in co-pending U.S. patent application Ser. No. 10/760,168, which application is incorporated by reference.
Referring to FIG. 1, two slotwall panels 10 mounted adjacent one another are shown. It should be understood that the slotwall panels 10 shown in FIG. 1 are only a portion of such panels that can extend longitudinally for any desired length. Typically, slotwall panels can be extruded in 8 feet long lengths to facilitate handling and installation. However, it should be understood that panels longer or shorter that 8 feet can fabricated and used. Further, a single panel can be used or an entire wall can be covered with panels as shown in FIG. 13. One embodiment of a hanger bracket 20 is shown mounted on one of the panels 10 and is shown with one example of a hook device 40 attached to the hanger bracket 20. Other well known and available hooks and hanging devices can be attached to one or more hanger brackets 20 as will be understood by one skilled in the art. While a few examples of types of hook and other storage devices that can be attached to one or more hanger brackets are disclosed in this application, one skilled in the art will understand that there are many available hooks and storage devices available on the market that could be used with the brackets and slotwall panels according to this invention.
Mounting of hanger bracket 20 to a slotwall panel 10 can be understood by referring to FIG. 2 and FIG. 3. In FIG. 2 and FIG. 3, a device 40 has been omitted from hanger bracket 20 to more clearly show hanger bracket 20 on the slotwall panel 10. Those skilled in the art will understand that in use a hook device or other storage device would be attached to hanger bracket 20. Hanger bracket 20 includes a central support portion 21, a generally “J” shaped hook 22 extending from one edge of support portion 21, and a generally “J” shaped hook 23 extending from an opposite edge of support portion 21. Generally “J” shaped hook 22 includes a first leg 24 extending generally perpendicular from the edge of support portion 21 and a second leg 25 extending from the distal end of first leg 24 generally parallel to support portion 21. Generally “J” shaped hook 23 has a first leg 26 extending generally perpendicular from the edge of support portion 21 and a second leg 27 extending from the distal end of first leg 26 generally parallel to support portion 21 in the same direction as leg 25. Thus, hanger bracket 20 has two downward opening “J” shaped hooks on opposite edges of support portion 21. Hanger bracket 20 also has a spring arm 28 extending from the edge of support portion 21 that divides generally “J” shaped hook 22 into two portions. Spring arm 28 extends in an opposite direction from leg 25. Referring to FIG. 2 and FIG. 3, generally “J” shaped hook 22 hooks over an edge 13 of a generally “T” shaped slat 12. Generally “J” shaped hook 23 hooks behind the lower adjacent half slat 16 in undercut 14. Spring arm 28 is positioned behind the upper adjacent slat 12 in undercut 14.
As shown in FIG. 2, leg 27 bears against the underside of the lower adjacent half slat 16 in undercut 14 biased against the underside of the slat by the spring arm 28. The force of spring arm 28 holds support portion 21 out of contact with the face of slat 12. Thus, hanger bracket 20 transfers the load on a device 40 through hanger bracket 20 to slotwall panel 10 by contact of leg 24 on edge 13 of slat 12, the contact of leg 25 against the inside edge of slat 12 and the force of spring arm 28 against the inside of the upper adjacent slat 12 in undercut 14. Leg 26 of “J” shaped hook 23 does not normally contact edge 13 of lower adjacent slat 12. Referring to FIG. 3, when a load is placed on device 40 that generates a moment sufficient to overcome the bias of spring arm 28, hanger bracket 20 pivots on “J” shaped hook 22 so that leg 27 engages the bottom wall 15 of “T” shaped slot 11. When hanger bracket 20 is loaded, hanger bracket 20 transfers the load on a device 40 through hanger bracket 20 to slotwall panel 10 by contact of leg 24 on edge 13 of slat 12, the contact of leg 25 against the inside edge of slat 12, the force of spring arm 28 against the inside of upper adjacent slat 12 in undercut 14 and by contact of leg 27 against bottom wall 15 of generally “T” shaped slot 11. The length of leg 26 holds hanger bracket 20 spaced from the face of slat 12 when hanger bracket 20 is loaded by items carried on device 40 so that leg 27 rests against the bottom wall 15 of slot 11. In the event hanger bracket 20 is overloaded by items placed on device 40, the pressure on leg 24 may be sufficient to deform the edge 13 of slat 12 allowing hanger bracket 20 to move down until leg 26 engages edge 13 of lower adjacent slat 12. In an overload condition, the load is spread over two adjacent slats 12 by generally “J” shaped hooks 22 and 23 in addition to the load spread by spring arm 28 to upper adjacent slat 12 and leg 27 to the bottom wall 15. Thus, hanger bracket 20 is locked in position on slotwall panel 10 by friction due to spring arm 28 whether loaded or unloaded. Accordingly, hanger bracket 20 and its attached device, whether loaded or unloaded, can not inadvertently be knocked off or dislodged from a slotwall panel 10.
Hanger bracket 20, together with any attached device such as device 40, can be mounted to a slotwall panel 10 by inserting spring arm 28 into the undercut 14 in a slot 11 far enough under the upper adjacent slat 12 for leg 25 to clear edge 13 of slat 12. Hanger bracket 20 can then be pivoted down against the moment of spring arm 28 until leg 27 clears the lower adjacent slat edge 13. Hanger bracket 20 can then be slid down over slat 12 until leg 25 rests on edge 13 with leg 27 bearing against the underside of the lower adjacent slat 12 in undercut 14. As mentioned above, hanger bracket 20 will be held in place by friction resulting from the moment of spring arm 28 bearing against the inside surface of the upper adjacent slat 12.
Turning to FIG. 4, a slotwall panel 10 can include four generally “T” shaped slots 11 that form three generally “T” shaped slats 12 and two half slats 16, one on each edge of panel 10. One edge of slotwall panel 10 can include a projecting connecting rib 17 and the other edge can include a mating connecting groove 18. As shown in FIG. 1, rib 17 and connecting groove 18 connect adjacent panels and, when so joined, the half width slats 16 of the adjacent panels form a full width slat.
As shown in FIG. 1 and FIG. 4, the bottom wall 15 of the generally “T” shaped slots 11 includes a longitudinal alignment groove 19 in the center of bottom wall 15. Alignment groove 19 can facilitate mounting of slotwall panels on a wall. Alignment groove 19 can provide a locating function to allow screws or other mounting devices to be aligned along slotwall panel sections. In a wall installation, screws 29 (see FIG. 13) can be driven through the slotwall panel along groove 19 into studs supporting the wall to mount the slotwall panel or panels to the wall as is well known to those skilled in the art. Mounting of plural slotwall panels is facilitated by connecting rib 17 and connecting groove 18 since another slotwall panel can be placed on a slotwall panel already attached to a wall and the slotwall panel will remain in place until fastened to the wall by screws or other suitable fasteners. Normally slotwall panels 10 can be mounted to a wall with connecting rib 17 directed up and connecting groove 18 directed down over rib 17 of an adjacent panel 10 if an adjacent panel is already mounted. Those skilled in the art will recognize that slotwall panels 10 can be mounted to a wall in the opposite direction if so desired, i.e. with rib 17 directed down and connecting groove 18 directed up. Applicants have found that locating the joint between adjacent slotwall panels in the center of a slat provides a stronger slotwall structure since torsional loads are minimal in the center of a slat as compared to joint locations in a slot or at an edge of a slat.
Referring to FIG. 4 through FIG. 4E, the dimensions of one embodiment of a slotwall panel 10 can be as provided in the following table. It should be understood that the following dimensions are approximate and that slotwall panels having different dimensions can be provided in accordance with the invention as desired.

Hanger bracket 20 can be formed of metal, such as steel. When hanger bracket 20 is formed with steel, hanger bracket 20 can be stamped from sheet steel. When hanger brackets 20 are formed of steel, raised surfaces or bosses 44, as shown in FIGS. 2 and 3, can be stamped in support portion 21 to provide attachment points for hook devices to be welded to the hanger bracket. After a hook device is attached to hanger bracket 20, the hanger bracket can be finished as desired, such as by painting the entire hanger bracket and hook.
Referring to FIG. 6B, spring arm 28 can extend up from first leg 24 at an acute angle of approximately 65°. As also shown in FIG. 6B the distal end 28′ of spring arm 28 can be bent to extend generally parallel to support portion 21 and leg 25. Referring to the embodiment shown in FIG. 4 through FIG. 4E, FIG. 5 and FIG. 6B the function of spring arm 28 can be seen. The thickness e of a generally “T” shaped slat can be 7.0 mm and the offset E of spring arm 28 can be 6.6 mm. When a hanger bracket 20 is installed on a slotwall panel 10 with spring arm 28 positioned behind an adjacent generally “T” shaped slat in undercut 14 and generally “J” shaped hook 22 is hooked over an edge 13 of a generally “T” shaped slat, interference of the distal end of the spring arm 28 with the inside of the adjacent “T” shaped slat will tend to rotate hanger bracket 20 away from the face of slotwall panel 10. When generally “J” shaped hook 22 is hooked over and engages an edge 13 of a generally “T” shaped slat 12, hook 23 will be positioned adjacent edge 13 of a lower adjacent generally “T” shaped slat 12. Leg 27 will be positioned behind the lower adjacent generally “T” shaped slat 12 in undercut 14. The moment produced by spring arm 28 pressing against the inside of upper adjacent “T” shaped slat 12 will drive leg 27 into contact with the inner surface of lower adjacent generally “T” shaped slat 12 thus friction locking hanger bracket 20 in place. When a device such as a hook device 40 is attached to support portion and a load is placed on the hook device, the downward force on the hook device will drive hanger bracket 20 toward slotwall panel 10 until leg 27 engages the bottom wall 15 of the generally “T” shaped slot 11. The length D of leg 27 can be 12.1 mm and can be slightly greater than the width d of undercut 14 which can be 5.0 mm plus the thickness e of slat 12 which can be 7.0 mm. Thus, hanger bracket 20 can be held out of contact with the face of slat 12 over which it is installed, whether loaded or unloaded. The distance A from the inside of first leg 24 of “J” shaped hook 22 to the inside of first leg 26 of “J” shaped hook 23 can be 75.2 mm compared to the center to center spacing a of slots and slats which can be 76.2 mm. When hanger bracket 20 is installed on a generally “T” shaped slat 12 with leg 24 of “J” shaped hook 22 engaging an edge 13, leg 26 of “J” shaped hook 23 will not engage edge 13 of adjacent slat 12. Thus, hanger bracket 20 can pivot between the position shown in FIG. 2 to the position shown in FIG. 3 as a load is applied to hanger bracket 20 by an attached hook device such as 40.
Referring to FIG. 7, FIG. 8 and FIG. 8A, a cabinet 50 is shown mounted on a slotwall panel 10. Cabinet 50 can be provided with another embodiment of hanger brackets mounted to one wall of cabinet 50. Cabinet brackets 30 can extend generally the full width of cabinet 50. Alternately, cabinet brackets 30 can extend less than the full width of cabinet 50 and multiple cabinet brackets 30 can be installed across the width of cabinet 50. Cabinet bracket 30 can include a support portion 31 for mounting the cabinet bracket 30 to a cabinet 50. A generally “J” shaped hook 32 can be provided on one edge of support portion 31. Another generally “J” shaped hook 33 can be provided on an opposite edge of support portion 31. Generally “J” shaped hook 32 can include a first leg 34 extending generally perpendicular to support portion 31 and a second leg 35 extending from the distal end of first leg 34 generally parallel to support portion 31. Generally “J” shaped hook 33 can include a first leg 36 extending generally perpendicular to support portion 31 and a second leg 37 extending from the distal end of first leg 36 generally parallel to support 31 and in the same direction as second leg 35. Cabinet brackets 30 can be dimensioned so that a cabinet bracket can be mounted to a slotwall panel without tipping the cabinet bracket 30. In order to mount a cabinet bracket without tipping the cabinet bracket 30, the length of second legs 35 and 37 should be less than width b the opening of “T” slots 11 in FIG. 4A. Similarly, the spacing of generally “J” shaped hooks 32 and 33 should correspond to center to center dimension a of the generally “T” shaped slots in FIG. 4.
Referring to FIG. 8, the dimensions of one embodiment of a cabinet hanger bracket 30 adapted for use with a slotwall panel, as shown in FIG. 4 through FIG. 4F, can be as provided in the following table. It will be appreciated by those skilled in the art that the following dimensions are approximate and that cabinet brackets having different dimensions can be provided in accordance with the invention as desired for use with slotwall panels having different dimensions.

Cabinet brackets 30 can be formed of metal. Cabinet bracket 30, as shown in FIG. 8, can be formed of extruded aluminum cut to lengths corresponding to the width of the cabinet or device to which the particular cabinet bracket will be attached.
As with the case of hanger bracket 20, cabinet bracket 30 can have a dimension A′ from the inside of generally “J” shaped hook 32 to the inside of generally “J” shaped hook 33 that is slightly less than the center to center dimension a of the slotwall panel in FIG. 4. When dimension A′ is slightly less than the center to center dimension a of slotwall panel, the load on cabinet bracket 30 produced by cabinet 50 will be on generally “J” shaped hook 32 and first leg 34 engaging edge 13 of generally “T” shaped slat 12. Because generally “J” shaped hook 32 engages an edge 13 of a generally “T” shaped slat 12 before generally “J” shaped hook 33, cabinet bracket 30 is held parallel to slotwall panel 10 and does not tip out at the top.
Referring to FIG. 9 and FIG. 10, the operation of cabinet brackets 30 can be seen. As the load on cabinet bracket 30 is increased by the load placed in cabinet 50, the edge 13 of slat 12 under generally “J” shaped hook 32 deforms allowing generally “J” shaped hook 33 to engage edge 13 of adjacent slat 12 thus increasing support for the cabinet bracket. Thus, cabinet brackets 30 initially transfer the load of cabinet 50 through generally “J” shaped hook 32 to the slotwall panel 10 by engagement of leg 34 with edge 13 of a generally “T” shaped slat 12. Generally “J” shaped hook 33 only engages the lower adjacent generally “T” shaped slat 12 when the load in cabinet 50 is sufficient to deform edge 13 of slat 12 on which leg 34 is resting.
Referring again to FIG. 8A, FIG. 11, FIG. 11A and FIG. 12 a plurality of square holes 39 can be provided in cabinet bracket 30 for mounting cabinet bracket 30 to cabinet 50. Cabinet 50 can be provided with a plurality of mounting holes 51 adjacent the top of cabinet 50 for a top cabinet bracket spaced to correspond to the spacing of mounting holes 39 in cabinet bracket 30. Mounting holes 51 can be round to permit mounting of a top cabinet bracket 30 in a fixed position adjacent the top of cabinet 50. One or more additional rows of mounting holes 52 can be provided below mounting holes 51 to allow mounting of one or more lower cabinet brackets 30. Mounting holes 52 can be vertically elongated slots to permit vertical adjustment of the lower cabinet brackets to insure that each cabinet bracket upper generally “J” shaped hook 32 engages a slat edge 13.
In order to install a cabinet 50 on a slotwall panel, a top cabinet bracket can be attached to cabinet 50 utilizing a plurality of mounting bolts 55 inserted with the head in cabinet bracket 30 and the threaded portion projecting through mounting holes 51 into cabinet 50. Mounting bolts can be a carriage bolt or similar fastening device that can be tightened without access to the head. Suitable fasteners, not shown, can be threaded on mounting bolts 55 and tightened to secure top cabinet bracket 30 to cabinet 50.

The rib and connecting groove configuration could also be interlocking with one panel hooking into and interlocking with an adjacent panel.
The material used to form slotwall panels 10 can be extruded foamed CPVC/PVC material as disclosed in co-pending U.S. patent application Ser. No. 10/747,421 mentioned above. Alternately, slotwall panels can be extruded of foamed PVC material as is known in the art. Slotwall panels can also be formed of wood panels by removing material to form the generally “T” shaped slots which in turn form the generally “T” shaped slats. Particle board material could be used to form the slotwall panels instead of wood or extruded foamed PVC material. Particle board slotwall panels could be formed by removing material to form generally “T” shaped slots. Alternately, particle board slotwall panels could be formed by attaching generally “T” shaped slats to a particle board. Plywood slotwall panels could be formed by removing material to form generally “T” shaped slots or by attaching generally “T” shaped slats as in the case of particle board.
FIGS. 19–27 illustrate a modular workbench storage system according to the invention that provides a heavy duty workbench and storage space for one or more modules that can dock underneath the workbench to minimize the area of the consumed in the room and thereby maximize the useful area of the workroom. When combined with the slotwall storage system and wall-mounted storage cabinet previously described, the workbench storage system provides the operator of a workroom with a highly flexible and very space-efficient storage system.
Referring to FIG. 19, a modular workbench system according to the invention is shown. Workbench 110 can include a leg assembly 111 at each end of the workbench and a top 130. Top 130 can be laminated hard wood or other sturdy, durable material as is well known in the art. In the embodiment shown in FIG. 19, top 130 can be 13⁄4 inches thick laminated hard wood maple strips that run lengthwise in top 130 to provide a strong heavy-duty work surface. The workbench 110 shown in FIG. 19 can be 8 feet long, 38 inches high and 25 inches deep to provide ample work surface and storage area for up to three modules. Those skilled in the art will understand that the length of the workbench can be longer or shorter as desired to provide space for docking two modules or more than the three modules, as shown in the embodiment of FIG. 19. For example, the workbench could be made 6 feet long and provide storage space for two modules. Likewise the height and width of the workbench can be adjusted as desired. The modules can include a drawer module 140, a storage cabinet module 150 and a refrigerator module 160. Refrigerator module 160 can be a low ambient temperature refrigerator as disclosed in co-pending U.S. patent application Ser. No. 10/744,556 and incorporated by reference.

In the embodiment of FIG. 21, vertical plate 116 can be 6 inches wide and mounting flange 117 can be 1 inch wide. Stringer 115 can be attached to leg assemblies 111 with a plurality of mounting bolts 118 and washers 118′ to the rear surface of rear legs 112 as is well known to those skilled in the art. While flat washers 118′ are shown, those skilled in the art will understand that lock washers could be used instead of, or in addition to flat washers 118′. Mounting bolts 118 can be threadably attached to legs 112 by weld nuts 124 attached to rear legs 112. Stringer 115 can have a plurality of vents 127 formed in vertical plate 116 to prevent build up of heat under workbench 110 as discussed in more detail below. Vent 127 can comprise a plurality of vertical slots 129 adjacent the upper edge of vertical plate 116. In the embodiment shown in FIG. 21, there can be 3 vents spaced across stringer 115 each having a plurality of slots 129. In the embodiment shown in FIG. 19 and FIG. 21 there can be 25 slots 129 in each vent 127 and the slots 129 can be 2 inches long and 1⁄4 inch wide with alternate slots 129 offset by 1⁄2 inch. While stringer 115 is shown in this embodiment as a separate component from leg assemblies 111 to facilitate shipping, it will be appreciated by those skilled in the art that the stringer 115 could be permanently attached to leg assemblies 111 as by welding. Stringer 115 can be fabricated of metal such as steel. Leg assemblies 111 and stringer 115 can be finished as desired such as by painting. Those skilled in the art will recognize that the dimensions of the stringer and vents can be adjusted as desired.
Referring to FIG. 21 and FIG. 23, each leg 112 can have a bottom wall 120 that can be welded into the bottom end of leg 112. Bottom wall 120 can have a threaded fastener such as a tee nut 121 welded in the center of bottom wall 120. A leveling foot 119 can be provided for each leg 112 that can include a threaded portion 122 fastened to foot 119 and adapted to be threaded into tee nut 121 in bottom wall 120. The top portion 122′ of threaded portion 122 can be provided without threads to prevent threaded portion 122 from backing all the way out of tee nut 121 such as when workbench 110 is being moved across the floor. Providing the top portion 122′ without threads can also facilitate assembly, in that one corner of the workbench can be lifted and a leveling foot 119 inserted into tee nut 121 without having to start the threads on threaded portion 122 upon insertion of threaded portion 122 into tee nut 121. Leveling foot 119 can have a pad 123 on the bottom surface to provide a non-slip surface on leveling foot 119. Pad 123 can be nylon or rubber or other material as will is well known to those skilled in the art. Those skilled in the art will understand that another form of leveling mechanism for some or all of the legs 112 could be provided as desired, or that a leveling mechanism could be omitted.
Elongated mounting holes 126 in top plate 114 and mounting holes 125 in mounting flange 117 can receive a plurality of fasteners 131 for attaching top 130 to the leg and stringer assembly 128. Fasteners 131 can be lag screws and pilot holes (not shown) can be pre-drilled in top 130 to facilitate locating and attaching top 130 to leg and stringer assembly 128. Mounting holes 126 are elongated in the plane of leg assembly 111 to allow for expansion and contraction of top 130 over the range of humidity conditions likely to be encountered in a non-climate controlled environment such as a basement, a garage or other outdoor work area. Thus, elongated mounting holes 126 are positioned to allow the width of the laminated hard wood maple top to expand and contract with changes in humidity. Mounting holes 125 in mounting flange 117 can be circular since laminated hard wood maple top 130 is unlikely to expand and contract along the direction of the laminated wood strips. In addition, use of round mounting holes 125 in mounting flange 117 can provide a sturdy workbench since the leg and stringer assembly can not shift under top 130 as the fasteners 131 can lock top 130 to the leg and stringer assembly 128. Those skilled in the art will understand that if top 130 is formed of strips of hard wood that run from front to back instead of side to side that mounting holes 126 could be round and mounting holes 125 elongated along the length of stringer 115 to allow for expansion and contraction in that direction.

While the modules disclosed in the embodiment of FIG. 19, FIG. 24, FIG. 25, FIG. 26 and FIG. 27 are approximately the same height when provided with casters as discussed above, those skilled in the art will recognize that the height of modules, with casters installed, could be substantially identical, or could be designed to differ in height as desired. The clearance space between the tops of modules 140, 150 and 160 coupled with vents 127 in stringer 115 provides adequate ventilation under workbench 110 when a refrigerator module 160 is in use and the condenser (not shown) is releasing heat under workbench 110. Those skilled in the art will recognize that vents 127 and/or the clearance space above modules 140, 150 and 160 can be changed as desired to provide more or less ventilation under workbench 110. Vents 127 can be located on stringer 115 to be centered with respect to each module, in embodiment of FIG. 19 and FIG. 21 three modules. Those skilled in the art will understand that if workbench 110 is modified to provide for docking of two or more that three modules the number of vents 127 in stringer 115 can be modified to correspond to the number of modules that can be docked under workbench 110.
While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation, and the scope of the appended claims should be construed as broadly as the prior art will permit.
