United States Patent SIDE-WALL STRUCTURE Edward M.

'Filed Mar. 10, 1958, Ser. No. 720,349

, 4 Claims. (Cl. 18934) This invention relates to improvements in a side-wall structure, and more particularly to the metal corner posts, their connecting means and the side-Wall panels.

Development engineers will find thisfabrication of a side-wall structure, with appropriate modifications and substitution of materials, can provide an important part in the designing and improving of diverse products and constructions. 1

A new hooking and insertion type ofassembly as exemplified in the present side wall structure can be used advantageously in designing products to facilitate production. This particular type of assembly dispenses with numerous fastenings heretofore utilized and consequently avoids the time-consuming procedure required by such fastenings. When assembled, the present side-wall structure is retained by tension induced in the assembly. In a product having four sides, the four side panels can be inserted in the side-wall structures at the same time by pressure to build the product.

Other important features will be apparent on later description of adaptation and of construction.

It is an important objective to provide a side-'wall structure that can be used in the making of shipping cases, milk bottle containers, cabinet furniture, bins, display cases, and double wall structures. These are but a few of the adaptations.

Another important objective can be realized by using window glass as the panels. Besides connecting the posts, the Wire fabric acts as a guard for the glass. The hooks on top guard the person handling the item against being cut by the glass edge on the glass panels. Vertical members are crimped at intersecting cross wires and are flat against the glass panels adding rather an ornamental effect in a product such as a household planter.

An important object is achieved in that the side-Wall structure can be collapsed by the removal of a stiffener panel and can be easily reassembled.

Briefly, the invention comprises a structure consisting of a corner or end pieces made by bending a strip of metal into a right angle section. Slots are then cut into the legs of the right angle section at predetermined longitudinally spaced positions in accordance with the mesh of the wire fabric to be inserted into the slots. Each leg of the right angle section has a channel with a reversed bend imposed thereon to provide a first groove adapted to receive the end of the wire fabric inserted in the slot and to provide a second groove adapted to receive a stiffening panel. When the side-wall structure is assembled, the Wire fabric and the panel or stiffening member are located in theappropriate grooves of a pair of such end pieces to provide a rigid structure. Of course, this structure can be made to be disassembled if desired.

The foregoing will appear more clearly in the following description when considered in connection with the accompanying drawing, in which:

FIG. 1 is a perspective view of the side-wall structure that is open at the top with one panel at one side partly slid up;

FIG. 2 is a perspective view from the inside of the structure. The wire fabric width is shortened here;

FIG. 3 is a top plan view of FIG. 2 when assembled;

FIG. 4 is a perspective view of the inside of a post, but shown with flat surfaces for clarity;

FIG. 5 is a side View detailing the loop and crimp in FIG. 2, and

FIG. 6 is a top plan view of a modification, the hori- Referring now by characters of reference to the side-wall structures are assembled into a box-like structure that includes a plurality of metal corner posts indi-- cated at-10. Connecting eachpair of posts 10 is a Welded wire fabric indicated at 11 and constituting a grille. In-.

partly slid out of channels 15 formed on the pair ofv corner posts 10 associated therewith to more clearly il-:

lustrate the construction.

The corner post 10 shown in FIG. 4 is of metal and is;

angular in shape. The legs of the corner posts 10 continue into inside bends making an S-shape, thereby forming opposed channels longitudinally disposed and indicated at 15. The inwardly opening grooves 21 of the channelsof a pair of corner posts 10 are arranged in oppositely facing direction as is best seen in FIG. 2, the inwardly opening grooves 21 being adapted to retain the end memface inwardly toward each other as is best shown in FIG.

2 and are adapted to receive the panel 12.

The assembly of the side-wall structure is best shown in FIGS. 2 and 3. The width of the wire fabric 11 is shortened in these figures of the drawing for illustration. The end vertical members 14 and 18 of the wire fabric 11 enter the posts 10 diagonally between the opposed channels 15, as is best visualized in FIG. 3. Posts 10 are then moved laterally so that vertical members 14 and 18 are retained in the inwardly opening grooves 21 of opposed channels 15. Horizontal wire members 16 are accommodated by slots 19 in the channels 15. The inwardly opening grooves 21 of the channels 15 of the pair of corner posts 10 retain the wire fabric part 11. The panel 12, shown fragmentary in FIG. 2, is now inserted into the opposed, outwardly opening grooves 22 of the channels 15.

FIG. 3 being a top plan view, shows this side-wall structure assembled. The assembly of the other sidewall structures follow the same procedure. The particular posts 10 shown have the channels 15 formed on the inside of the right angle legs, and the Wire fabric 11 in this form of the invention is therefore on the outside of the structure and the panel 12 is inwardly thereof. It is also contemplated to reverse the angle of bend of the post so that the wire fabric 11 will be on the inside of the structure and the panel 12 on the outside without changing the nature of the invention.

The vertical members 20 of the wire fabric 11 are detailed in FIG. 5. They are crimped where they in-' tercept the transverse members 16 and their top ends are hooked for panel containment. The use of hooks at the top end of vertical members 20 is optional.

FIG. 6 illustrates a modification in which horizontal members 16 would also be hooked to contain the panel 12, thereby dispensing with the outwardly opening grooves 22 previously described. This requires the inwardly opening grooves 21 of channels 15 to contain the wire fabric 11 permanently. The modified side-wall structure of FIG. 6 can also be constructed with the panel 12 either on the inside or on the outside as mentioned previously.

The foregoing description and detail of structure and assembly is believed to be fully informative, the detail is in an instructive, rather than in any restrictive sense,
