Wall-mounted shelf support clip
SUMMARY OF THE INVENTION 
     This invention relates to a clip for attachment to a wall to support a shelf, particularly a ventilated closet shelf of the general type shown in U.S. Pat. No. 3,598,064. 
     In accordance with the present invention, a wall-mounted clip presents an upwardly-facing recess at the front for snugly receiving a horizontal rod at the back edge of a shelf, and a flexible and resilient fin whose lower free end overlies the shelf edge rod when it is seated in the recess. This fin is bent back when the shelf edge rod is being inserted into the clip recess and it springs out into overlying relationship with the shelf edge rod after the latter is fully seated in the recess to prevent the accidental or inadvertent removal of the shelf from the clip. 
     A principal object of this invention is to provide a novel wall-mounted support clip for a shelf which is constructed to retain the shelf in place on the clip. 
     Another object of this invention is to provide such a clip which enables the edge of a shelf to be readily inserted in the clip and securely retained therein against accidental or inadvertent removal. 
     Further objects and advantages of this invention will appear from the following description and appended claims, reference being had to the accompanying drawing forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

     DETAILED DESCRIPTION 
     Referring to FIG. 1, the present clip comprises a generally flat vertical segment 10, a forwardly and upwardly extending hook 11 attached to the front of the vertical segment 10, and a flexible and resilient fin 12 attached to the front of the vertical segment above the hook 11. 
     As shown in FIGS. 2 and 4, the vertical segment 10 presents a flat back surface 13 for engagement with the front of the wall 14 of a building or other support structure for the clip. Typically, this wall 14 will be the wall of a closet in which several clips in accordance with the present invention will be mounted to support the back edge of a shelf. At its back edge the shelf presents an elongated horizontal rod 15 of circular cross-section which will be seated on the hook segment 11 of the clip and immediately below the fin 12, as explained hereinafter. 
     In the particular embodiment shown the clip has a horizontal shank segment 16 extending rearward from the vertical segment above the flexible and resilient fin 12. This horizontal segment 16 and the vertical segment 10 in front of it are formed with a cylindrical bore 17 into which the shank of a mounting screw may be threadedly inserted. At the front the vertical segment 10 of the clip is formed with a cylindrical counterbore 18 for receiving the head of the mounting screw. 
     A pair of flexible and resilient fingers 20 and 21 are joined to the shank segment 16 at its back end above and below the bore 17. The upper finger 20 presents a transverse shoulder 20a extending down from its attachment to the shank segment 16. The lower finger 21 presents a similar upwardly extending transverse shoulder 21a. Normally, as shown in FIG. 1 and in phantom in FIG. 4, the fingers 20 and 21 are resiliently biased apart slightly but they may be squeezed together manually before being inserted in an opening 14a in the wall 14. Preferably, this wall opening has a size and shape such that the shank segment 16 of the clip has a force fit in it. For example, the opening 14a may be originally of circular cross-section while the shank segment 16 of the clip is rectangular in cross-section. Preferably, also, the axial length or the shank segment 16 is substantially equal to the thickness of the wall 14 so that when the back face 13 of the vertical segment 10 of the clip is flush against the wall 14, the fingers 20 and 21 on the clip will assume their undeformed phantom line position in FIG. 4. When the mounting screw is inserted through the bore 17 in the clip it will engage the shoulders 20a and 21a and spread the fingers 20 and 21 apart to the full line position in FIG. 4. 
     The hook segment 11 on the front of the vertical segment 10 of the clip curves forward and upward from it through a 90° arc and terminates in a straight upper end 11a extending parallel to the vertical segment 10. The inside face of the hook segment 11 and the front face of the vertical segment 10 define a recess which is open at the top and is semi-cylindrical at the bottom to snugly receive the edge rod 15 on the shelf, as shown in FIG. 4. 
     The clip is formed with a reinforcing rib 22 extending perpendicularly in front of the vertical segment 10 and supporting the hook segment 11 from below midway along its length. 
     In accordance with the present invention, the flexible and resilient fin 12 normally extends forward and downward at an acute angle in front of the vertical segment 10 of the clip, as shown in FIGS. 1 and 4. When the edge rod 15 on the shelf is being inserted on the hook segment 11 (FIG. 3) it bends the fin 12 back against the vertical segment 10 of the clip. When the edge rod 15 on the shelf is in place in the recess defined by the hook segment 11 and the adjacent front face of the vertical segment 10 of the clip, the fin 12 springs back to its normal undeformed position (FIG. 4) closely overlying the shelf rod 15 to prevent its removal from the recess in the clip. In this position the lower free end of the retainer lip 12 is just slightly above the level of the top of the hook segment 11. 
     In order to permit the deliberate removal of the shelf from the clip, the top front edge of the hook segment is formed with a depression 11b at the middle which extends below the level of the bottom edge of fin 12, as shown in FIG. 3. This depression permits the insertion of the tip of a screw driver or the like beneath the fin 12 to lift it up and permit the removal of the edge rod 15 of the shelf from the recess on the front of the clip. 
     Preferably, the entire clip is formed as a one-piece body of suitable resilient plastic material. 
     Where the support wall 14 is of wood instead of plaster the shank 16 and fingers 20 and 21 on the clip may be omitted and a wood screw may be inserted through the bore 17 in the front segment 10 of the clip directly into the wall to mount the clip on the wall.
