   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, slot tracks, cabinets removably mounted to the slotwall panel and/or slot tracks, 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 workbenches 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 slot track. The slot track has a plurality of slots with at least one undercut sidewall with adjoining slots forming a slat having edges defined by the slots. The slots further have a bottom wall generally parallel to and spaced inwardly from the face of the at least one slat. The organization system includes one or more removable mounting brackets having a support portion for attaching a device to the bracket. The mounting brackets include a first “J” shaped hook on one edge of the support portion opening in a first direction to hook over an edge of a slat into the undercut sidewall. The mounting brackets include a second “J” shaped hook on an opposite edge of the support portion opening in the first direction to hook over an edge of the adjoining slot into the undercut sidewall. 
   Another aspect of 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 and at least one slot track. The slotwall panel has a plurality of slots with at least one undercut sidewall forming a plurality of slats having edges defined by the slots. The slots in the slotwall panel have a bottom wall generally parallel to and spaced inwardly from the face of the slats. The slot track has two slots with at least one undercut sidewall forming a slat having edges defined by the slots. The slots in the slot track have a bottom wall generally parallel to and spaced inwardly from the face of the slat. The organization system includes one or more removable mounting brackets usable on the slotwall panel and on the slot track. The mounting brackets include a support portion for attaching a device to the mounting bracket and a first “J” shaped hook on one edge of the support portion opening in a first direction to hook over an edge of a slat into the undercut sidewall. The mounting brackets also include a second “J” shaped hook on an opposite edge of the support portion opening in the first direction to hook over an edge of the adjoining slot into the undercut sidewall. 
   Another aspect of the invention provides a unique solution to the need for space-efficient, organized storage for a workroom via a workroom organization system comprising one or more slot tracks in combination with a wall-mounted cabinet and a floor supported workbench with at least one nesting mobile storage cabinet. The organization system provides for space-efficient, organized storage of workroom items, such as tools and supplies used in a workroom. The slot tracks are mountable on a wall of the workroom and have at least two slots defining at least one slat. The organization system further includes one or more removable mounting brackets having a first “J” shaped hook on one edge opening in a first direction to hook over an edge of the at least one slat. The mounting brackets include a second “J” shaped hook opening in the first direction to hook over an edge of a slot adjoining the slat engaging the first “J” shaped hook. The wall-mounted storage cabinets have at least one mounting bracket to engage at least one slot track. The workbench has a work surface and multiple legs extending from the work surface to support the work surface above a floor and defines a workbench recess beneath the work surface. A mobile storage cabinet having 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. The mobile storage cabinet has wheels extending 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 mounting brackets mounted on the plurality of slot tracks and to 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 workroom organization system permits the easy relocation of the workroom items and rearrangement of the at least one wall-mounted storage cabinet, workbench, and at least one mobile storage cabinet as needed over time as the quantity and mix of workroom items changes.

   DESCRIPTION OF THE INVENTION 
   In accordance with the present invention a slotwall and slot track 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  and/or a slot track  210  having a plurality of generally “T” shaped slots  211  forming at least one generally “T” shaped slat  212  are provided with a hanger bracket for mounting a device on the slotwall panel or slot track. The slotwall panel and/or slot track can be formed of extruded polyvinyl chloride material. Co-pending patent application Ser. No. 10/747421, discloses one such material, which patent application is incorporated by reference. The slotwall and/or slot track 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 and/or slot track storage system can also be used in a workroom or workshop, or in commercial and industrial locations. The slotwall and/or slot track storage system can be used in conjunction with a Modular Workbench System as disclosed in co-pending 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. Slotwall panels  10  with suitable hanger brackets can be used alone or in combination with slot tracks  210 , and slot tracks  210  with suitable hanger brackets can be used alone or in combination with slotwall panels  10  and/or in combination with a Modular Workbench System mentioned above to form a flexible, space-efficient workroom storage system. 
   Referring to  FIG. 1 , a slotwall panel  10  is shown. It should be understood that the slotwall panel  10  shown in  FIG. 1  is only a portion of the panel 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 the panel  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  FIG. 5  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 outside length D of leg  26  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 let  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 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. 4B . 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 . Next, one or more lower cabinet brackets 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 vertical slot mounting holes  52  into cabinet  50 . Suitable fasteners, not shown can be threaded on mounting bolts  55  and left loose to permit adjustment of the position of the one or more cabinet brackets  30  on cabinet  50  relative to the slotwall panel  10 . Cabinet  50  can then be mounted on slotwall panels that have mounted or attached to a wall structure. The top cabinet bracket  30  is first hooked on a selected slotwall panel slat  12  with leg  34  engaging a slat edge  13 . Next, the lower cabinet bracket or brackets  30  are vertically adjusted so that each generally “J” shaped hook  32  engages a slotwall panel slat  12  with leg  34  engaging a slat edge  13 . After the one or more lower cabinet brackets  30  are all positioned hooked over a slotwall panel slat  12  with leg  34  engaging a slat edge  13  the fasteners can be tightened securing the one or more cabinet brackets to the cabinet  50 . As mentioned above, the vertically elongated mounting holes provide sufficient vertical adjustment to allow multiple cabinet brackets to be employed for mounting a cabinet to a plurality of slotwall panels  10  with each cabinet bracket transferring load from the cabinet  50  to the slotwall panel to spread the load in cabinet  50  across multiple slotwall panels  10  and slats  12 . 
   Referring to  FIG. 13 , hanger brackets  20  can be combined to support plural mounting hooks  40 ′.  FIG. 13  also illustrates yard tools carried on the mounting hooks on a slotwall storage system occupying a section of a wall. As shown in  FIG. 13 , slotwall panels  10  can be fastened to a wall using a plurality of fasteners such as screws  29 . In the embodiment shown in  FIG. 13  a plurality of screws  29  are fastened through the slotwall panels  10  in each slot  11  spaced apart by the distance between underlying studs or wall support structures. Those skilled in the art will understand that fasteners  29  can be used in alternate generally “T” shaped slots  11 , or other patterns as desired depending on the anticipated loading on the slotwall panels  10 . Likewise, fasteners  29  could be driven into alternate studs or wall supports. The specific mounting hooks shown and the yard tools carried are only examples to show how the slotwall storage system can be used. Those skilled in the art will understand that many other hooks or storage devices could be attached to one or more hanger brackets to store any desired objects. In the embodiment of  FIG. 13 , two hanger brackets can be connected with a pair of connecting rods  41  to which three mounting hooks  40 ′ are attached. The connecting rods can be welded to hanger brackets  20  and mounting hooks  40 ′ can be welded to connecting rods  41 . The combined mounting hook device can be mounted on a slotwall panel  10  in the same manner as a single hanger bracket as described above. Those skilled in the art will recognize that the combined mounting hook device shown in the embodiment of  FIG. 13  is only one possible arrangement of multiple mounting hooks and that more or less than three mounting hooks could be attached to two or more connected hanger brackets. 
   Referring to  FIG. 14 , a cabinet bracket  30  can be attached to a shelf  42  to support shelf  42  on slotwall panels  10 . In the embodiment shown in  FIG. 14 , a cabinet bracket  30  can be attached to shelf  42  using threaded fasteners as used in connection with the cabinet as described above, or permanently attached to shelf  42  by welding. Shelf  42  can be mounted on slotwall panel  10  by inserting “J” shaped hooks  32  and  33  into adjoining slots  11  and sliding shelf  42  and cabinet bracket  30  down over adjoining slat edges  13 . 
   As one of skill in the art should recognize, hanger brackets  20  can be combined to support a basket (not shown) on slotwall panels  10 . In the embodiment two hanger brackets  20  can be attached to a basket by welding or by any other known connection means. The basket can be mounted on a slotwall panel in the same manner as a single hanger bracket as described above in detail. 
   Referring to  FIG. 15  and  FIG. 16 , another embodiment of a slotwall panel  10 ′ is shown. In the embodiment of  FIG. 15  and  FIG. 16  repeating ruler markings  45  and  46  can be provided on the bottom wall  15  of generally “T” shaped slot  11 ′ on either side of groove  19 ′. Ruler markings  45  can be repeating 1–16 inch marks while ruler markings  46  can be repeating 1–24 inch marks. Repeating ruler markings can facilitate mounting of slotwall panels on conventional stud wall construction. Once a stud is located for a mounting screw  29 , adjacent screws can be inserted at the same number in the repeating sequence as the first screw since most stud walls are built on 16 inch or 24 inch centers. The provision of the repeating markings eliminates the need to measure and mark the location of subsequent studs for mounting screws once the first mounting screw  29  is driven into a stud. As shown in  FIG. 16 , the repeating markings can be provided in alternate generally “T” shaped slots  11 ′. Those skilled in the art will recognize that other patterns of repeating markings could be used such as in one generally “T” shaped slot per slotwall panel  10 ′. 
   Referring to  FIG. 17  another embodiment of slotwall panel is shown. The slotwall panel  10 ″ can be fabricated of metal such as extruded aluminum. The slotwall panel  10 ″ of the embodiment shown in  FIG. 17  can have dimensions a″, b″ and d″ corresponding to the same dimensions in slotwall panel  10  as shown in  FIG. 4 . The slotwall panel  10 ″ can support hanger brackets  20  and cabinet brackets  30  in the same manner as described above even though the thickness e″ of slat  12 ″ is less than the thickness e of slat  12 . As shown in  FIG. 17 , a groove  49  can be provided in the center of slat  12 ″. The provision of a slat groove  49  will make the appearance of slats  12 ″ the same as a joint between adjoining slotwall panels  10 ″ where adjoining half slats  16 ″ meet. Those skilled in the art will recognize that a groove  49  can be provided in slat  12  of the embodiment of the slotwall panel  10  shown in FIG.  4 – FIG. 4E  to provide the same function as in the embodiment of  FIG. 17 . 
   Referring to  FIG. 18  and  FIG. 18A , other embodiments of the slotwall panel are shown. In  FIG. 18  slotwall panel  10 ′″ can have a connecting rib  17 ′ and connecting groove  18 ′ that are offset toward half slat  16 ′″ instead of offset toward the opposite surface of the slotwall panel as in the embodiment shown in FIG.  4 – FIG. 4E . In  FIG. 18A , slotwall panel  10 ″″ can have a connecting rib  17 ″ and connecting groove  18 ″ that are centered in slotwall panel  10 ″″. Those skilled in the art will understand that the connecting rib and connecting groove can have a configuration other than as shown in FIG.  4 – FIG. 4E  and  FIG. 18  and  FIG. 18A . Such other rib and connecting groove configurations could include semicircular, triangular, trapezoidal or other shapes. 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 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. Particleboard material could be used to form the slotwall panels instead of wood or extruded foamed PVC material. Particleboard slotwall panels could be formed by removing material to form generally “T” shaped slots. Alternately, particleboard slotwall panels could be formed by attaching generally “T” shaped slats to a particleboard. 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 particleboard. 
     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 1¾ 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 non-provisional patent application docket number US20020323 incorporated by reference. Those skilled in the art will understand that other modules can be provided as desired. In addition, less than three modules can be provided for use with workbench  110  and more than one of a particular module can be used with workbench  110  as desired by the user. 
   The modules can be provided with heavy duty casters, as described in detail below, to facilitate movement for docking underneath the workbench  110 , rearrangement of the modules underneath the workbench, or to facilitate positioning away from the workbench for cleaning under the workbench or for use as a mobile work surface.

   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.

   Turning to  FIG. 29 , one embodiment of a hanger bracket  20  is shown mounted on the panel  210  and is shown with one example of a hook device  40  attached to the hanger bracket  20 . Another embodiment of a hook device  40 ′ is shown in  FIG. 13 . 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 slot tracks according to this invention. 
   Mounting of hanger bracket  20  to a slot track  210  can be understood by referring to  FIG. 29 . The slot track  210  as shown in  FIG. 28  through  FIG. 32  can include the same slot and slat geometry as a slotwall panel  10  as described conjunction in  FIG. 1  through  FIG. 4 , and can be used in conjunction with the same hanger brackets  20  that can be used with slotwall panels  10 . Referring to  FIG. 29  generally “J” shaped hook  22  hooks over an edge  213  of a generally “T” shaped slat  212 . Generally “J” shaped hook  23  hooks behind lower edge  216  in undercut  214 . Spring arm  28  is positioned behind upper edge  216  in undercut  214 . Hanger bracket  20  interacts with slot track  210  in the same way as with a slotwall panel  10  as described above in connection with  FIG. 1  through  FIG. 4 . Thus, hanger bracket  20  is locked in position on slot track  210  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 slot track  210 . 
   Hanger bracket  20 , together with any attached device such as device  40 , can be mounted to a slot track  210  by inserting spring arm  28  into the undercut  214  in a slot  211  far enough under the upper edge  216  for leg  25  to clear edge  213  of slat  212 . Hanger bracket  20  can then be pivoted down against the moment of spring arm  28  until leg  27  clears the edge  213  of lower edge  216 . Hanger bracket  20  can then be slid down over slat  212  until leg  25  rests on edge  213  with leg  27  bearing against the underside of the lower edge  216  in undercut  214 . Thus, hanger bracket  20  can mount on slot track  210  the same as hanger bracket  20  mounts on a slotwall panel  10 , see  FIG. 2 . 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 edge  216  in undercut  214 . For convenience in describing attaching of a bracket  20  to a slot track  210 , edges  216  have been described as upper and lower edges  216 . Slot track  210  as shown in the embodiment of  FIG. 28  through  FIG. 32  can be symmetrical so that “upper” and “lower” has no significance other than a reference to understand the description since slot tracks  210  can be mounted on a wall with either edge “up”. 
   Referring to  FIG. 30  and  FIG. 31 , the dimensions of one embodiment of a slot track  210  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 brackets  20  as described above in  FIG. 2 ,  FIG. 5  and  FIG. 6A  including the dimensions of the embodiment of a hanger bracket  20  described in conjunction with those figures can be used with a slot track as shown in  FIG. 28  through  FIG. 32 . It will be appreciated by those skilled in the art that the dimensions referenced above are approximate and that a hanger bracket having different dimensions can be provided in accordance with the invention as desired for use with slot tracks having different dimensions. 
   Turning to  FIG. 32 , another embodiment of slot track  310  is mounted on an edge of a slotwall panel  10 . When slotwall panels  10  are used to cover less than a full wall of a workroom, the upper or lower edge of a slotwall panel  10  can present a connecting rib  17  or a connecting groove  18  on the exposed edge(s) of the slotwall panel(s)  10 . In order to provide a finished edge, a slot track  310  having a half slat  316 ′ on one edge can be provided. Slot track  310  can include a connecting groove  318  on one edge adjacent half slat  316 ′ in order to mate with the connecting rib  17  of a slotwall panel  10 . The dimensions of the half slat  316 ′ and connecting groove  318  can be the same as the corresponding components of a slotwall panel  10  described above. While slot track  310  is shown with a connecting groove  318  on one edge, those skilled in the art will appreciate that slot track  310  can be provided with a connecting rib, not shown, on one edge in lieu of connecting groove  318  in order for the slot track  310  to mate with an exposed connecting groove  18 . Should a connecting rib, not shown, be provided it can have the same dimensions as the connecting rib  17  included in slotwall panels  10 . Those skilled in the art will understand that slot tracks  310  having a connecting rib and other slot tracks having a connecting groove can be provided for use with slotwall panels having both edges exposed to form a finished storage system. 
     FIG. 33  illustrates a modular workbench storage system  110  in combination with a slot track storage system in a workroom. The modular workbench storage system  110  can include 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 all as described above in connection with  FIG. 19  through  FIG. 27 . When combined with the slot track 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. In the embodiment shown in  FIG. 33 , a plurality of slot tracks  210  are shown mounted on a wall of the workroom. Some of the slot tracks  210  have one or more hangers  40  installed on the slot tracks. Three wall cabinets  50  are shown mounted on a pair of slot tracks  210  mounted on the workroom wall over the workbench system  110 . Slot tracks  210  can be mounted on the workroom wall spaced so that wall cabinets can be mounted in the same manner as wall cabinets are mounted on slotwall panels as described above in connection with  FIG. 7  through  FIG. 12 . Wire form shelves  42 ′ having brackets  20  can be mounted on the workroom wall for storing items off the floor of the workroom. 
     FIG. 34  illustrates another embodiment of workroom having a modular workbench storage system  110  in combination with a slotwall and slot track storage system in a workroom. The workroom in this embodiment has a plurality of slot tracks  210  mounted on a wall of the workroom, and also has a plurality of slotwall panels  10  covering a portion of one section of a wall of the workroom. A pair of the slot tracks  210 ′ and  210 ″ are shown mounted to align with slots in a slotwall panel  10 . In addition, a slot track  310  is shown positioned at the top of series of slotwall panels to provide a finished top edge. When one or more slot tracks  210  are mounted adjacent one or more slotwall panels with slots in the slot tracks aligned with slots in the slotwall panel, devices such as a wall cabinet  50  can be installed partially on a slotwall panel and partially on a slot track. Slot tracks  210  can be dimensioned so that they can be mounted on a wall spaced apart an even number of slot track widths apart with the slots  211  lined up with slots  11  of a slotwall panel  10 . Then, if desired, additional slot tracks  210  can be added between slot tracks already mounted on a wall, in each case with slots  211  aligned with the slots  11  of a slotwall panel  10 . Those skilled in the art will also recognize that one or more slot tracks  210  can be mounted at any convenient height on a wall of a workroom to support hanger brackets for storing tools and equipment in the workroom, or for supporting shelves, baskets or other storage devices. 
   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.
