Sept. 6, I966 s. T. SHEARS SHELF SUPPORT Filed Nov 26, 1965 Imam? I Jinan? T. Shelli 5'5 United States Patent 3,270,995 SHELF SUPPORT Stuart T. Shears, Belmont, Mass, assignor to United-Carr Incorporated, Boston, Mass, a corporation of Delaware Filed Nov. 26, 1965, Ser. No. 509,732 2 Claims. (Cl. 248-224) This invention relates generally to fastening devices and more specifically to a fastening device utilizing a stud and an adapter or socket.
An object of the present invention is to provide a fastening device having a stud, Welded or otherwise attached to a support without the necessity of forming an aperture in the support and an adapter element having means of engaging with an article to be held by using a pair of spaced slots for engaging the studs.
Another object of the present invention is to provide a fastening device engaged to a support and an adapter element including a pair of slots spaced from each other, having an arm extending from each side edge of the adapter element.
Other objects of the invention will, in part, be obvious and will, in part, appear hereinafter.
In the drawings:
FIG. 1 is an end elevation of the adapter;
FIG. 2 is a bottom plan view of the adapter shown in FIG. 1; and
FIG. 3 is a side elevation showing the adapter engaged to a pair of studs on a support and engaged within the cavity of a shelf support element.
There is shown in the drawings an adapter socket element formed of a flat, thin stock, having abase portion 12 including a pair of spacedparallel side edges 14 and a pair ofarc end edges 16. In close proximity to each of theside edges 16 anarm 18 is formed, extending away from thebase portion 12. Each of thearms 18 has a terminal end bent toward the other to provide aknuckle 20. Afirst slot 22 and asecond slot 24 are formed through thebase portion 12, spaced from each other. Each of theslots 22, 24 include a large, substantiallycircular opening 26, 26a and a smaller, substantiallycircular opening 28, 28a respectively connected by anecked channel 30, 30a. Theslots 22, 24 lie on the long longitudinal axis of thebase portion 12 with theirsmall openings 28, 28a on the same side of their respectivelarge openings 26, 26a as shown in FIG. 2. Alocking tab 32 extends from one of thearced end edges 16 and is bent back to extend partially over thelarger opening 26 of thefirst slot 22. Thelocking tab 32 has afree engagement edge 34 directed along a plane parallel to the plane of the base.
The pair ofstuds 36, to be used with theadapter element 10, each comprise an enlarged head portion 38 and acylindrical shank portion 40 extending, in right angle relationship, from the enlarged head portion 38. Theshank portion 40 is of smaller diameter than the head portion 38 and has afree terminal end 42.
Theshelf support element 44 is normally used to hold a shelf by placing one on each of a pair of spacedparallel side walls 46, of the interior of a refrigerator for example. Theshelf support element 44 comprises abody portion 48, frequently formed of plastic material, extending from abase 50 having a greater Width than thebody portion 48. Thebase 50 has ashallowed depression 52 which opens into a comparativelydeep cavity 54. Thecavity 54 extends through the remaining portion of thebase 50 and well into thebody portion 48 as shown in FIG. 3.
Thestuds 36 are either soldered or otherwise attached to theside wall 46 without forming an aperture through theside wall 46. The twostuds 36 are placed in spaced,
3,270,995 Patented Sept. 6, 1966 ice aligned relationship and a plastic liner 56 is placed in abutting relationship to theside wall 46 and has holes formed therein through which the twostuds 36 may pass.
The diameter or width of theadapter socket element 10 at itsknuckles 20 is greater than the width of thecavity 54 and therefore when thearms 18 are pushed into thecavity 54 they are flexed inwardly and thereby hold themselves in engagement with theshelf support element 44. Thesocket adapter element 10 is usually engaged to the alignedstuds 36 prior to its engagement with theshelf support element 44. Engagement of theadapter socket element 10 with thestuds 36 is accomplished by passing the head portions 38, which are smaller diameter than thelarge openings 26, 26a, through thelarge openings 26, 26a. In order to pass thestud 36 through the opening 26, thelocking tab 32 is flexed away from thebase portion 12 by the head portion 38. Thebase portion 12 is then pushed to pass theshanks 40 through their respectivenecked channels 30 and 30a until theshanks 40 come to rest within thesmall openings 28, 28a of theslots 22, 24. Thestud 36 engaged within theslot 22 as it is passed into thesmall opening 28 is passed beyond theengagement edge 34 of thelocking tab 32, allowing thelocking tab 32 to snap back behind the head portion 38, locking theadapter socket element 10 to thestuds 36. Theshelf support element 44 can then be engaged with theadapter socket element 10.
With reference to the foregoing description it is to be understood that what has been disclosed therein represents only a single embodiment of the invention and is to be construed as illustrative rather than restrictive in nature; and that the invention is best described by the following claims.
What is claimed:
1. The combination of a fastening device and a support, said fastening device comprising a pair of studs and an adapter socket element, said adapter element socket having a base portion, a first and second slot formed through said base portion, said slots being spaced from each other along a long axis of said base portion, each of said slots comprising a large opening and a small opening connected by a necked channel, a locking tab extending from an edge of said base portion, over the area defined by said large opening of said first slot, said locking tab having a free engagement edge and lying on a plane in substantially parallel relation with said base portion, each of said studs having a head portion and a shank portion extending from said head portion in integral right angle therewith, said shank having a free end, each of said studs being secured at said free end of said shank to said support without perforation of said support, said large opening of said slots having a diameter greater than said head portion of said stud and said head portion being in abutting superposed relation to said base adjacent said small opening and said free engagement end of said locking tab being in approximate relation to said head portion of the stud engaged with said first slot and said fastening device having means of engaging an article to be held.
2. The combination of a fastening device and a support as set forth in claim 1 wherein said means of engaging an article to be held comprises a pair of spaced legs extending from said base portion.
