The cabinet structure also allows a vertical perforated board to be fixed to the back of the structure for product display.

The features of the invention will become clearer from the following description of the illustrated embodiments.

Like features are provided with like reference numerals throughout the drawings.

Referring to the drawings, a modular cabinet construction is shown, which is designed to meet the needs of a standardized unit with certain basic parts having selectable accessories. , the structure is adaptable to make the most efficient use of its internal volumetric space with selectable storage structures. The cabinet structure can be used alone or in combination with similar or compatible units, giving the individual user unlimited options for shelving space, partitions, enclosure space, etc.

FIG. 1 shows an embodiment of a modular cabinet structure according to the invention, which comprises a base 1 having a rectangular profile, a pair of vertical sides spaced apart from each other and a top portion thereof. It has side portions 2, a back portion 3, and a top portion 4 whose front edges are sloped so as to taper toward the minute. Alternatively, the leading edges of the sides can be vertical, as shown in FIG. 18. The base 1 consists of, for example, a flanged channel member of appropriate length to which plywood (for example, about 1.27 cm thick) is bolted, and the plywood is connected to a partition channel member 27 (FIG. 8). tab 2
It supports a flat metal base member suitably drilled to receive the 8 as required. The load-bearing sides 2 are secured to their outer surfaces in the vicinity of their respective leading and trailing edges by means of channel members 5 facing inwardly at a distance from each other.
Increased rigidity and reinforced. Vertically spaced holes 5a in the base of the channel mate with corresponding holes in the sides 2. Said side part 2
are preferably made of sheet metal and are provided with an outwardly bent flange 2a at their leading edge and an inwardly bent flange 2b at their trailing edge. The slope of the front surface of the cabinet provided by the tapering of the sides towards the top facilitates the visibility of items displayed in the cabinet as well as their storage and retrieval.
However, such a concept requires shelves of different width dimensions and makes it difficult to easily or frequently change the vertical spacing of the shelves. To overcome this difficulty, a shelf is proposed whose width dimension is easy to adjust, and which allows a given shelf to be selectively supported at different vertical levels with different width dimensions as appropriate. Side part 2 is assembled.

FIG. 1 shows an example of a support structure with four shelves 6 and a similarly constructed top 4 having a uniform length between the sides 2 and extending from the bottom to the top. The width dimension is shown to gradually decrease towards the end. Each shelf 6, with the exception of the uppermost shelf, consists of two complementary full-length sections 7 and 8, which are nested into each other so as to be extendable in their width, which is their front-to-back dimension. The sliding relationship is adjustable. This two-part extendable width shelf is clearly shown in FIGS. 4, 5 and 6. The rear part 7 has a suspended end 9, the lower part of which is offset outwardly by a step 10. In the front part 8, a flange 12 is formed by bending the inner part of the suspended end part 11 of the part inward,
The flange has the same depth dimension as the step 10 of the rear part so as to properly rest on the step 10, and the end of the front part and the end below the step of the rear part are different from each other. are on the same plane. In front of the end 11, the ends 9 below the step 10 of the front and rear parts hang down to a common level with a ramp 13, a shallowly inwardly sloping lower edge provided at the end. Said front and rear parts are provided with a vertical notch 14 with an enlarged mouth at such hanging ends rising on said ramp. Said front part 8, with an end flange 12 which rests on a step 10 of said rear part, rests on the rear part 7 and is extendable to the width dimension permitted by the length of its inner flange end 12. The rear part 7 comprises two notches 14 spaced apart from each other at each end, while the front part 8 has a rear part which rests on and rests on said rear part and which has said flange end. Each end is provided with only one such notch near the leading edge, since longitudinal displacement is constrained by the interlocking connection between the leading end and the leading end. In the wider shelf near the bottom of the cabinet, two cutouts can be provided at each end of the front section.
The rear part has a double trailing edge with a shallow hanging flange 15, and the front part is finished with a hanging flange 16 that extends down to the depth of the notched end of the part and across said edge. There is.

In order to support shelves 6 with adjustable width dimensions on said cabinet sides 2 at selected width dimensions and to facilitate their installation and removal, said sides 2
A grid of vertically spaced, laterally aligned, keyhole-shaped perforations or holes 17 are provided in the holder, and novel self-suspending bolts 18 are provided. Bolt 18 has a head capable of passing through the main circular portion of said hole and a head on each side for slidably fitting into a narrow slot depending in said hole 17, as shown in FIGS. Flat part 1
9, the collar extending beyond the flat portions on both sides by approximately the thickness of the metal plate of the shelf and having a knurled nut 21.
It continues to the threaded shaft portion 20, which is a reduced diameter portion that carries the. Once the vertical height of the shelf to be placed has been determined, the bolts 18 are placed in the appropriate row of holes 17 and the flats of the collar are pushed down into the narrow slots of the holes, thereby loosening them. The bolt with attached nut 21 is self-suspended. The rear part 7 is then easily applied so that the notch 14 of the beveled end 13 is in position on the inner part of the collar of the bolt, holding the rear part firmly in place. The nut is then tightened firmly, and then the front part 8 is applied so that its rear parts are in overlapping relation and the notch 14 in its end is on the bolt 18 and firmly tightened in place. It will be done.

Although the aforementioned front and rear portions or each shelf portion can be directly supported by the aforementioned bolts and nuts, for example, the aforementioned holes 17
It can be supported on a rectangular cylindrical bracket with holes suitably spaced to fit the lateral side 2, which bracket is bolted vertically to said side 2 in a suitable manner.

A hole 17 in said side 2 as shown in FIG.
In this method, two bolt holes 17 for the support of said rear part 7 are always at a constant distance from said back, while one or two bolt holes for said front part are provided on said side. Following the slope or taper of the leading edge of section 2. Furthermore, a given width dimension can be obtained by using the front section 8 in a number of extended positions, and at one level selecting said front section either in the narrowest width position or in the next narrowest width position. Understand what you can do. Additionally, the user can change the front portion or outer shelf portion to the desired or preferred size by adjusting the inclination angle of the narrow slot. For example, the three width dimensions of the outer shelf portion may be When used, the slots are 7, 6 and 5, respectively.
By tilting it in the direction of time, it can be made wide, medium, and narrow.

In FIG. 1, the uppermost shelf 6 is angled so that it slopes downwardly at the front. The front part of the shelf is supported by bolts as described above, and the upper rear edge is supported by the base of an L-shaped bracket 49 having a series of holes in the arm, and which bracket is supported by bolts as described above. 6 by means of a suitable hole 17 in the side 2 and a bolt 18 placed in the appropriate one of said holes in said bracket.

As a variant of the shelf, each shelf section is preferably reinforced by a reinforcing member 22 having a U-shaped cross-sectional shape and extending in the longitudinal direction, the reinforcing member being welded to the lower surface of the shelf section. or a side wall portion with an outer flange fixed by other means, and a central groove 23 provided in the U-shaped base portion and opening downwardly.

The partition is then pushed up to compress the filler material until its lower edge overcomes the low wall or flange 27b of the channel 27 below;
Once cast into the shallow channel, it is biased downwardly under compression of the filler material to seat within the channel. This ensures that the upper edge of the partition is held in the slot 25 of the reinforcing member 22. The partition can be easily removed or reinstalled by lifting the partition against the downward compressive bias of the elastic filler 24 and reversing the operations described above. In addition to being able to separate the shelves into compartments by the vertical partitions, horizontally spaced holes are provided in adjacent spaced vertical partitions that cooperate with each other, and the holes are disposed between the partitions. Channels 27 similar to those described above can be used to horizontally support the shelves. The tabs 28 of the channel 27 are inserted into appropriate matching holes and are inserted with the underlying flange 27a to support the shelf. A horizontal partition is inserted into such a channel (located at the same height on said partition), so that said vertically partitioned compartment is divided into a plurality of smaller horizontally arranged compartments. subdivided into rooms.

A second row of brackets 76 arranged in opposite directions, i.e. with the flat sides of the angles facing rearwardly, is then hooked into the slots of the front vertical rows on both sides, thereby The perforated board 78 is stably and reliably supported without being displaced back and forth.

FIG. 17 shows yet another embodiment of the cabinet construction according to the invention, in which an inner bracket 80 is secured to the cabinet side 2. As shown in FIG. Bracket 80 is provided with a plurality of grooves for supporting one or more hanger rods 82, which provide support structure in place of the shelves. A single bar 82 allows support for costume hangers, and parallel double bars allow support for T-shaped items such as field racks, shovels, and brooms. In order to periodically prevent the contents within the cabinet structure from being exposed to public view or access, a roll-up shielding means, a pull-down, retractable cover 84, is provided, which covers the side 2. It has a metal pull rod 86 whose both ends move in facing grooves provided in the flange 2a of the front edge.

According to the present invention, modular cabinet structures can be assembled in both side-by-side and back-to-back relationships. The cabinet structure itself constitutes a kiosk in, for example, a shopping center mall, allowing a retailer to arrange a plurality of cabinets around a central work area and display the merchandise therein. Cabinet structures for storage warehouses have larger height dimensions than those for retail applications; for example, the former has a height dimension of about 177.8 cm and the latter has a height dimension of about 124.5 cm.

FIG. 18 shows a combination of multiple cabinet structures according to the present invention. The side part 2 of the cabinet structure has a rectangular shape.
Two wide cabinet structures 90 are secured to four narrow cabinet structures 92 in the same manner as described above. Cabinet structures 90, 92 and cast strip 60 are secured together in the same manner as described above. Shelf 6 is suitably positioned in all said cabinet structures. These shelves may have a fixed width or expandable width (fourth
Figure) can be used. A number of shelves are separated by vertical partitions 29. Vertical suspension flanges 94 with holes for receiving bendable ears on either side of nameplates 96 are provided on the front faces of some of the shelves. drawer 98
are removably mounted on the plurality of shelves.
The front faces of these drawers 98 are also provided with holes for receiving name plates 96 as shown. The vertical wall 30 is shown secured to several of the shelves 6 via jaws 32 and 34 supported on the partition 29. On the front vertical hanging flanges 16 of some of the shelves, a plastic label strip 100 is inserted into the groove 1 on the back of the strip.
02 (see FIG. 5 for details) and is held in place by friction. The label strip 100 is also provided with holes for receiving the bendable ears on either side of the name plate 96. It is thus possible to identify or index the various locations and parts of the cabinet structure. These label strips also prevent the lower edge of the flange 16 from scratching the hands of the person using the cabinet structure.

The enclosed space or box 104 is configured and maintained as desired.

For the most efficient operation of the cabinet structure, it should be placed as horizontally as possible. To enable this, the cabinet structure can be supported by legs 120 (FIG. 1A) similar to a typical screw configuration with adjustable vertical levels, each leg having a foot pad 122; The base 1 includes a shaft screw 124 that is received in a screw socket 126 on the lower surface of the base 1. Further, each leg 120 has the shaft screw 124.
A cylindrical hard collar 128 is provided which circumscribes and has the same length as this. The collar is made of brittle plastic, for example. When each leg 120 is screwed into the screw socket until the upper end of the collar 128 abuts the underside of the base 1, a similar starting point for adjustment of each leg is established. In other words, the sleeve or collar acts as an initial stopping point to bring all legs to equal height prior to adjustment for uneven floors. If the leg needs to be lowered to horizontally support the cabinet structure in that position, the leg is pulled out of the receptacle the desired amount, and if the leg needs to be adjusted upward, the leg is pulled out of the receptacle by the desired amount. The leg breaks the collar and is screwed into the receptacle the desired amount. This feature greatly saves time in adjusting the cabinet structure since the legs only need to be adjusted once.

Accordingly, the present invention provides a cabinet structure that fully satisfies the objects and advantages set forth above. It will be clear from the foregoing that the cabinet structure according to the invention is excellent in its flexibility and efficient use of space. for example,
If desired, high and low cabinet structures can be combined. 1st
A cabinet structure having tapered sides, such as that shown in the figures, may be coupled in a back-to-back relationship with a cabinet structure having rectangular shaped sides, such as that shown in FIG. Although the invention has been described with respect to specific embodiments thereof, many substitutions, modifications, and modifications will be apparent to those skilled in the art in light of the foregoing description. Accordingly, the present invention includes such substitutions, modifications, and modifications that fall within the scope of the claims.
