STORAGE AND DISPLAY RACK Filed Aug. 16, 1965 2 Sheets-Sheet 2 United States Patent 3,332,558 STORAGE AND DISPLAY RACK James D. Wilson, Long Beach, Calif., assignor to Banner Metals Inc., Compton, Calif., a corporation of Ohio Filed Aug. 16, 1965, Ser. No. 480,071 Claims. (Cl. 211-175) The present invention relates to storage racks, and it relates more particularly to adjustable storage display racks which may be assembled to different widths so as to meet different customer requirements.
Collapsible storage display racks are in widespread use at the present time. Such racks are intended, for example, to support a plurality of display t-rays in a spaced, tiered relationship.
In the past, the storage racks have been tailor made to order in different widths to meet the requirements of different customers. This has raised a problem, however, in that the production of the storage racks in the past has had to proceed more or less on a custom basis. That is, it has been the usual practice to manufacture storage racks of a particular width only when an order was received for that particular width. Therefore, orders could not normally be filled promptly or on an off the shelf basis.
In practicing the present invention, however, storage racks can be constructed in a mass quantity and held in stock. This is because the racks need not be constructed to any particular width. Then, when an order is received for racks of a particular width, a simple adjustment of the racks constructed in accordance with the invention establishes them at that width. Therefore orders can be filled promptly, and storage racks of any desired width can be supplied without the need for production being tailored to that particular width.
An object of the present invention, therefore, is to provide an improved storage rack assembly which is capable of being adjusted to any desired width to meet the particular size of the trays to be supported in the rack.
Another object of the invention is to provide such an improved storage rack assembly which can be set and maintained to such a desired width.
The storage display rack to be shown and described herein is of the foldable, wheeled type. Its width can be adjusted, in accordance with the concepts of the invention, so as to permit different tray sizes of a range of 18-25 inches in width, for example, to be received therein. The trays are held in a tiered relationship in the rack.
The storage rack assembly to be described includes a plurality of wedge-type adjustable strap, or bracket assemblies, each of which is bolted, riveted, or otherwise fastened in place When the assembly is set to a desired width. These brackets serve to hold the assembly rigidly to the selected width, as will be described.
The features of the invention which are believed to be new are set forth with particularity in the claims. The invention itself, however, together with further objects and advantages, may best be understood by reference to the following description, when the description is taken in conjunction with the accompanying drawing, in which:
FIGURE 1 is a perspective elevational view of an improved storage and display rack constructed in accordance with one embodiment of the invention, and established at a predetermined width;
FIGURE 2 is an elevational view of the rear wall of the storage and display rack of FIGURE 1, with the width adjusted to a narrower dimension;
FIGURE 3 is a perspective exploded view of an adjust able strap assembly which is incorporated into the construction of the storage and display rack of the illustrated embodiment of the invention;
Patented July 25, 1967 "ice FIGURE 4 is a sectional view, taken substantially on the line 4-4 of FIGURE 2, but on an enlarged scale, showing the manner in which the adjustable strap assembly of FIGURE 3 serves to engage the bar of the rear wall to hold the assembly rigidly to a predetermined width; and
FIGURE 5 is a perspective view of a bracket assembly which serves to support display trays on the storage rack in a tiered relationship.
The display and storage rack shown in FIGURE 1, for example, includes a first pair of upright support posts, designated 10 and 12, and a second pair of upright support posts designated 14 and 16. The upright support posts 10, 12, 14 and 16 in the illustrated embodiment, are each formed of a pair of spaced parallel rods or bars. A plurality of wheels 20 are pivotally mounted to the lower ends of respective ones of the support posts in appropriate supporting brackets. The wheels may be in the form of double ball-bearing swivel casters. They serve to provide mobility to the display rack.
A series of transverse shelf brackets 22 are welded, or otherwise aifixed to the posts 10 and 12. These shelf brackets extend between the posts at spaced intervals. The shelf brackets may be welded, or otherwise affixed, to the bars making up the posts 10 or .12. A shelf bracket 22 is shown more clearly in FIGURE 5.
The shelf brackets 22 may extend at an inclination between the upright posts 10 and 12, so that the display trays (not shown) supported thereby may be inclined towards the front of the storage rack.
A second series of similar shelf bracket 24 are welded or otherwise afiixed to the upright support posts 14 and 16, and they are aligned with corresponding one of the shelf brackets 22.
It will be appreciated that the display trays (not shown) are supported in any convenient manner on the self brackets 22 and 24 when the storage rack is set up in the manner shown in FIGURE 1.
A pair of adjustable rear wall members designated generally as 26 and 28 form the rear wall of the display rack assembly. These adjustable rear wall members are made up of a series of bars or rods, as shown, including, for example, pairs of spaced transverse rods 30, 31 and 32, 33; and diagonal rods 30a, 31a, 32a, and 33a, as shown. The ends of the transverse rods extend around one of the bars of each of the respective upright posts 12 and 16 to form knuckle-joints 30b, 31b, 32b, and 3312, as shown. This permits the side walls formed by the shelf brackets 22 and 24 to be folded around the rear wall members 26 and 28.
Each of the rear wall members includes an upper pair of spaced, transverse bars 34 and a lower pair of spaced, transverse bars 36. These latter pairs of transverse bars are also folded around one of the bars of the respective upright posts 12 and 16 to form knuckle-joints 34a and 36a, similarly to the coupling of the transverse bars 30 and 32.
The members 26 and 28 making up the rear wall also have a pair of upright bars 40 and 42. The transverse bars 30, 32, 34 and 36 are welded, or otherwise aflixed, to the upright bars 40 and 42.
A first aper-tured strap member 50 is shaped to receive the upper transverse bars 34 of each of the members 26 and 28, as shown in FIGURE 1, for example. Likewise, a second apertured strap 52 is shaped to receive the lower pair of transverse bars 36 of each of the members 26 and 28.
The configuration of the straps 50 and 52 is best shown in FIGURE 3. The transverse bars are received in channels at the edges of the straps, such as the straps 52, as shown, for example, in FIGURE 4.
The bars 34 and 36 slide along the respective straps 50 and 52, as the aforesaid side walls are moved together, until the display rack has a predetermined width. Then, a pair of additional wedging straps 54, 56 are attached to the upper and lower straps 50 and 52 by appropriate fasteners, such as rivets 58, bolts or other fastening means.
The rivets 58 extend through certain ones of the ape-rtures 50a and 52a in the straps 50 and 52. The rivets 58, or other fastening means, serve to hold each of the straps 56 firmly against the transverse bars 34 and 36 in a Wedging action, such as shown in FIGURE 4, for example, so as to hold the assembly firmly to the predetermined width.
An additional strap assembly 61, similar to the strap assemblies discussed above, may be provided at the bottom of the front of the rack, as shown in FIGURE 1. A further bar 62 is coupled to the posts and 14, likewise forming knuckle-joints 62a, so as to permit a folding action of the assembly. The bar 62 is selected to have a length corresponding to the predetermined width of the storage and display rack, as established by the aforesaid adjustments of the rear wall.
The above-described components of the display rack may be composed, for example, of galvanized steel, high tensile aluminum, or any other appropriate material. A bright zinc finish may be provided, for example, when the basic construction of the assembly is steel.
It will be appreciated that when the assembly is set up as shown, for example, in FIGURE 1, it may conveniently be folded into a flat configuration without the need for removing any of the component parts. Then, when the assembly is opened out to the position shown in FIGURE 1, a plurality of display trays may be inserted into the shelf brackets 22 and 24 and supported therein in a til-ted tiered relationship. When the trays are in place, the display rack itself is held firmly in the position shown in FIGURE 1.
It will also be appreciated that storage racks such as shown in FIGURE 1 may be constructed on a mass production basis, and held in stock. Then, when an order is received for a particular number of racks, required to accommodate trays of a particular length, then the assemblies are set up. This is achieved quickly and conveniently, merely by riveting the straps 54 and 56 to the strap 50 with the assembly at the particular width and by attaching a bar of a selected length, such as the bar 62, to the forward side of the assembly.
The assembly of FIGURE 1 is shown as set to a particular Width A, for example, whereas the assembly of FIGURE 2 is shown as set to a narrower width, designated A.
The invention provides, therefore, an improved storage rack assembly for holding trays in a tiered, inclined position, for example. The assembly of the invention is particularly advantageous since it can be manufactured to any of a variety of predetermined Widths, this being achieved in a simple and expeditious manner.
