DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT. I

A storage unit embodying this invention is shown in FIG. 1, and generally comprises a lower cabinet 12 having an opening across the front thereof which is closable by slidable doors 14 and '15. A cabinet shelf 16 is lockingly connected to the top of the cabinet 12, and a pair of and panels 18 are lockingly coupled to the cabinet shelf 16 and to a second shelf 20 to retain the shelves l6 and 20 in parallel, vertically spaced relation. Additional pairs of end panels 19 can be connected to the second shelf 20 and to subsequent shelves 22 to form a storage unit having any desired number of parallel shelves mounted above the cabinet 12.

The cabinet 12 is formed as a molded plastic unit having interconnected bottom, rear, and side walls 24, 26, and 28. The front and top faces of the cabinet 12 are substantially open. The front face, however, includes a lip 30 extending'upwardly a short distance from the bottom wall 24, and front panels 32 project laterally inwardly a short distance from the side walls 28 to help locate the sliding doors 14 and 15, as will be hereafter described in greater detail. One or more hanger holes 25 are formed through the rear wall 26, as shown in FIG. 2, to permit the cabinet to be mounted on a vertical surface such as a wall, and if desired, rearwardly projecting spacers 27 shown in FIGS. 3 and 4 can be formed on the back side of said rear wall 26 to assure that the unit will hang vertically with respect to the wall. A downwardly projecting pair of ribs 34 are also formed on the underside of the bottom .wall 24 to support the cabinet 12 in a level position on a horizontal surface. 1

As best shown in FIG. 2, each of the cabinet side walls 28 has a pair of laterally spaced hooks 36 which project upwardly and outwardly from itsupper edge. Similarly, hook-like projections 38 project upwardly from the top of each of the front panels 32 and the top of the rear wall 26. The projections 38 on the rear wall are disposed in alignment with the projections 38 on the front panels 32. The hooks 36 and the projections 38 locate the cabinet shelf 16 in position atop the cabinet 12, and lockingly interconnect said shelf and cabinet.

As shown in FIGS.-1 and 3, the cabinet shelf 16 is conveniently formed as a plastic molding, and comprises a horizontally disposed supporting surface 40 having a border skirt 42 projecting equidistantly upwardly and downwardly'from its periphery. A pair of laterally spaced end slots 44 and a pair of side slots 46 are formed in the shelf surface 40 at each end of the shelf. The slots 44 are positioned to receive the hooks 36 formed on each cabinet side wall 28, and the side slots 46 are positioned to receive the projections 38 on the cabinet rear wall 26 and front panels 32. To connect the shelf 16 to the cabinet l2, the shelf is placed over the cabinet 12 with the slots 44 and 46 in alignment with the cabinet books 36 and projections 38. The shelf is then pressed downwardly with the hooks 36 being received in the slots 44 and snapped against the upper face of the shelf surface 40.

To accommodate the sliding doors l4 and 15, an upper track 48 is formed on the underside of the shelf 16 and a lower track 49 is formed on the cabinet bottom wall 24. As shown in FIG. 3, the upper track 48 is comprised of a forward rib 50, an intermediate rib 52, and a rearward rib 5.4, each of which projects downwardly from the underside of the cabinet shelf 16 and extends across the face of the cabinet near the front thereof. The ribs 50, 52, and 54 thus define a forward groove 56 and a rearward groove 58 for slidably receiving the upper edges of the doors 14 and 15, respectively. The lower track 49 comprises a forward rib. 60

rearward groove 66 for slidably receiving the lower edges of the doors 14 and 15, respectively. The grooves 64 and 66 of the lower track 49 are disposed in vertical alignment with the grooves 56 and 58 of the upper track 48 and act in combination therewith to slidably support the doors 14 and 15 across the frontal width of the cabinet.

The doors 14 and 15 are each slightly longer than one-half the frontal width of the unit so that when the doors are closed, they will slightly overlap near the center of the unit as seen in FIG. 1 to thereby cover and close the entire front face of the cabinet. If desired, handles 68 or the like can be mounted on each of the doors 14 and 15 to facilitate the easy opening and closing thereof.

One of the end panels 18 for interconnecting the cabinet shelf 16 and the second shelf is shown in detail in FIG. 5. Although only one end panel 18 is shown by way of example, the other end panel 18, as well as the upper end panels 19, are identical thereto. Conveniently, the end panel 18 is formed as plastic molding, and generally includes an end wall 70 bordered on each side by a side skirt 72 projecting inwardly at a right angle to the plane of the end wall 70. The bottom edge of the end wall 70 is rectilinear, while the lower portion of each side skirt terminates in a downwardly projecting finger 76 extending laterally inwardly from said skirt.

Adjacent their upper ends, the skirts 72 are offset inwardly toward each other to define a pair of horizontally disposed ledges 77. The upper edges of the end wall 70 and the portions of the skirts 72 adjacent thereto project inwardly for short distances from said end wall and skirts to form a horizontal supporting platform 78 parallel with the ledges 77. A pair of hooks 80 project upwardly and laterally outwardly from the inner edge of platform 78 along the upper edge of the end wall 70. Said hooks are identical both in general shape and spacing to the books 36 formed on the cabinet side walls 28. Similarly, ahook 84 projects upwardly and inwardly from the platform 78 at the top of each skirt 72.

The end panels 18 are connected at their lower and upper ends between the shelves 16 and 20, and in a like manner, the end panels 19 are connected between the shelves 20 and 22. If desired, additional end panels may be connected to the shelf 22 in the same manner to support still a fourth shelf (not shown). In this manner, any number of shelves can be assembled onto. and above the cabinet 12 in a vertically spaced parallel relationship.

As shown in FIGS. 6 and 7, in assembling the shelves and end panels, the end panels 18 are connected at their lower ends to the opposed ends of the cabinet shelf 16 with their skirts 72 facing inwardly toward each other. The end wall 70 of each panel 18 is located between the upwardly projecting cabinet hooks 36 and the border skirt 42 at one end of the shelf 16. The lower edge of said end wall 70 and the lower edges of the skirts 72 outside the extent of the fingers 76 rest on the shelf supporting surface 40 with said fingers projecting through the slots 46. The fingers 76 are received in slots 46 outside the cabinet projections 38 with their upper edges 86 engaging the underside of the shelf 16 to thus connect the panels to said shelf.

The hooks 80 and 84 at the top of the panels 18 connect the shelf 20 to said panels and thus to the cabinet 12. Said shelf, as well as shelf 22, is identical to the cabinet shelf 16 with the exception that the track 48 can be omitted therefrom. Thus, as shown in FIGS. 6 and 7, the central supporting surface 21 of the shelf 20 rests upon the platforms 78 of the panels 18, and the hooks 80 and 84 are snap-fit into the end and side slots 44 and 46 for lockingly mounting said shelf on the panels 18.

The end panels 19 and shelf 22 are connected to shelf 20 in the same manner that end panels 18 and shelf 20 are connected to shelf 16. Thus, as shown in FIGS. 6 and 7, the fingers 76 on panels 19 are received in the side slots'46 in shelf 20 with their upper edges 86'abutting the underside of the shelf supporting surface 21, and the lower edges of the end wall 70 and the portions of the skirts 72 outside the extent of said fingers resting on the supporting surface 21 immediately inwardly from the shelf skirt 85. As shown, the fingers 76 are received in the slots 46 on shelf 20 outwardly from the hooks 84 on panels 18 with their lower edges engaging the ledges 77 on the panels 18.

The upper ends of the panels 19 have their hooks 80 and 84 inserted through and snap-fit in the end and side slots 44 and 46 in the supporting surface 23 of shelf 22. Thus, with the underside of its supporting surface 23 resting on the platforms 78 on the panels 19 and the hooks 80 and 84 engaging the top face of said surface, the shelf 22 will be lockingly retained on said panels.
