6 Claims, 5v Drawing Figures 1 ERECTIBLE SHELVING BACKGROUND OF THE INVENTION The present invention relates to the construction of erectible metal shelving, and more particularly to a manner of connecting a bracing member to the supporting posts to brace the posts in an upright position.

Erectible metal shelving generally comprises a set of at least four upright metal supporting posts and metal shelves mounted horizontally between the posts with the posts being at the corners of the shelves. One type of such shelving is shown in the US. Pat. to Rosenberg,

No. 2,631,913, issued Mar. 17, 1953, entitled Erectible Shelving, and the US. Pat. to Rosenberg, No.

2,719,633, issued Oct. 5, I955, entitled Erectible Shelving and Brackets Employed Thereby. In such shelving it is necessaryto brace the supporting posts to firmly-support them inan upright position. It is desirable that such bracing members be narrow, sheet metal 'beamswhich extend horizontally between the supporting posts so that the bracing members do not block access to the shelves from any side of the shelving. Also, such horizontally extending bracing members could be used to support the shelving, serve as bin fronts or closed bases for the shelving. However, the connection between the narrow bracing member and the supporting post must provide the supporting post with the necessary bracing action. Also, it is desirable that the connection provide for ease of assembling and disassembling the shelving without the need of any special tools.

SUMMARY OF THE INVENTION An erectible shelving including a hollow supporting post which is substantially rectangular in cross-section and has a plurality of longitudinally spaced openings in one wall thereof. A bracing member has a connector secured to one end thereof which releasably secures the bracing member to the supporting post. The connector includes portions which engage at least two walls of the supporting post, and fingers which extend through the openings in the supporting post and engage the innersurface of the one wall of the supporting post.

BRIEF I DESCRIPTION OF DRAWINGS DETAILED DESCRIPTION Referring initiallyto FIG. 1, theshelving assembly of the present invention is generally designated as 10. The shelving assembly comprises a plurality of upright metal supporting posts 12, at least four of which are required, arranged at the corners of a rectangle. Brac- 2 1. ing members 14 extend horizontally between and are secured to the two rear supporting posts, and similar bracing members extend between and are secured to the two front supporting posts. Connecting members, not shown, secure the front and rear supporting posts together in spaced relation.

As shown in FIGS. 2, 3 and 4, each of the supporting posts 12 is an elongated member of hollow sheet metal construction. The supporting post 12 comprises a rear wall 16, a pair of parallel side walls 18a and 18b, and a pair of aligned

front walls

20a and 20b, all of which form a hollow rectangular configuration. A pair of juxtaposed,

parallel flanges

22a and 22b extend forwardly from the adjacent edges of the

front walls

20a and 20b respectively. Each of the

front walls

20a and 20b has a plurality of spaced, elongated rectangular openings 24a and 24b respectively therethrough. The openings 24a and 24b are arranged in alignment with their longest edges extending longitudinally along the supporting post 12. The

flanges

22a and 22b have a plurality of longitudinally spaced holes 26a and 26b respectively therethrough. Each of the holes 26a in the flange 22a is in alognment with a separate hole 26b in the flange 22b.

Each of the bracing members is an elongated, narrow, sheet metal channel 28 having a connector 30 at each end thereof. As shown in FIGS. 2, 3 and 4, each of the connectors 30 is a metal sheet having a front section 32, a middle section 34 extending perpendicularly from the back edge of the front section 32, and a rear section 36 extending perpendicularly from the middle section 34 away from but substantially parallel to the front section 32. As shown in FIGS. 2 and 4, the front section 32 is of a length corresponding to the length of the

flanges

22a and 22b of the post 12. The middle section 34 is of a length corresponding to that of the

front walls

20a and 20b of the post, and the rear section 36 is of a length corresponding to that of the side walls 18a and 18b of the post. The connector 30 is of a height so as to extend over and slightly beyond three of the rectangular openings 24a and 24b in the front walls of the posts.

.The connector 30 has three spaced openings 38 therethrough, each extending from the rear edge of the front section 32 completely across the middle section 34and partiallyacross the rear section 36. Each of the openings 38 is of a height corresponding to the height of a rectangular opening 24a and 24b in the

post front walls

200 and 20b. The openings 38 are spaced apart a distance corresponding to the spacing between the rectangular openings 24a and 2412. Flat fingers 40 extend from the back edge of the front section 32 at each of the openings 38 with the top edges of the fingers being slightly below the tope edges of the openings 38. As shown in FIG. 4, the fingers 40 are bent slightly toward the rear section 36 and then extend parallel to the rear section. A lip 42 extends downwardly from the end of each of the fingers 40. The inside edge 44 of each lip 42 is tapered away from the rear edge of the front section 32 so as to provide a camming surface. A mounting flange 46 extends perpendicularly from the rear edge of the rear section 36 away from the plane of the front section 32. The mounting flange 46 is of a height to fit into the channel 28, and is secured thereto, such as by bolts 48. However, the mounting flange46 may be secured to the channel 28 by any known means,

such as rivets or welding, or may be an integral part of the channel.

To secure a bracing member 14 to a supporting post 12, the connector 30 is placed adjacent the supporting post 12 with the front section 32 of the connector being juxtaposed a flange of the supporting post and the fingers 40 being in alignment with three of the rectangular openings in the supporting post. Theconnector 30 is then moved to insert the fingers 40 into the rectangular openings until the middle section 34 of the connector 30 abuts the front wall of the supporting post, and the rear section 36 of the connector is juxtaposed to a side wall of the supporting post. At this point the lips 42 of the fingers 40 are completely within the hollow portion of the supporting post. The connector 30 is then pressed vertically downwardly to move the lips 42 of the fingers 40 behind the front wall of the supporting post as shown in FIG. 5. As the lips 42 move downwardly in the supporting post, the camming surfaces 44 of the lips engage the front wall of the supporting post to cammingly lock the lips in the supporting post. Thus, the connector 30 is secured to the supporting post 12 without the need of any special tools, except perhaps for a hammer. To remove the bracing member, it is only necessary to lift the connector 30 upwardly until the fingers 40 engage the top ends of the rectangular openings, and then pull the fingers out of the post.

Thus, there is provided an erectible shelving having bracing members which can be mounted horizontally between the supporting posts at any point along the supporting posts. The bracing members have connectors which can be easily secured to and removed from the supporting posts without the need for any special tools. Also, the connectors firmly secure the bracing member to the supporting posts. In addition, since the connector has portions which engage three surfaces of the supporting posts over a length longer than the width of the bracing member, there is provided a great load bearing strength between the bracing member and the supporting posts. The bracing member in addition to providing support for the supporting posts can be used to support shelving, serve as a bin front or base for the shelving.
