Sanford, Woodbury, Conn., assignor to The Autoyre Company, Incorporated, Oakville, Conn., a corporation of Connecticut l Application April 12, 1946, Serial No. 661,564

This invention relates to shelf brackets, more particularly to brackets adapted to be secured to a wall .or similar surface for supporting a shelf in removable relation to the brackets, and the invention has for an object the provision of inexpensive, rugged and attractive shelf brackets of this character.

Shelf brackets heretofore proposed have usually been provided either with means permitting permanent attachment of the shelf to the brackets by screws .or the like, or with shelf-engaging hook portions at the front ends of the brackets for engaging the front edge of the shelf to prevent forward displacement thereof and to hold the shelf securely against the wall or similar support on which the bracket is mounted.

The use of front end hooks of this character limits the use of the brackets to shelves having a width equal to the length of the shelf-supporting arm of the bracket, and accordingly requires the production of various sizes of brackets to accommodate shelves of different width. In recognition of this disadvantage of shelf-supporting brackets having front end fhooks, it has heretofore been proposed to form the hook on a separate slide or adjustable member carried by theV shelf-supporting arm of the bracket adapted to lbe adjusted forwardly or rearwardly in accordcomms. (o1. 248-247) 2 vention, reference should now be had to the drawings in which:

In carrying outthe invention in one form I provide a shelf bracket comprising a wall-engaging arm from which projects a forwardly eX- tending shelf-supporting arm, and resilient clamping means are provided disposed adjacent the rear end of the shelf-supporting arm for firmly and frictionally clamping the rear edge portion of the shelf to retain the shelf in position on the bracket and prevent accidental displacement of the shelf. More particularly, the clamping means includes a plastic or resilient insert member including a forwardly sloping surface up which the shelf may ride when inserted into the clamping means so as to reduce the -possibility of breakage when glass shelves are em- Fig.`11is a fragmentary side elevational view .of the portion of the shelf bracket shown in Fig. 10;

Fig.` V12 is a fragmentary top plan view of ythe wall end of still another form of shelf bracket embodying the present invention; and j Fig. 13 is a fragmentary side elevational view of the portion of the shelf bracket shown in Fig. 12.

Referring first to Figs. '1 to 9 of the drawing, the invention is shown as embodied in a shelf bracket I0 having a wall-engaging arm II the central portion of which is forwardly embossed to provide a strengthening panel I2 which is provided with suitable apertures I3 for receiving -lscrews or other suitable fastening means. by

which the wall-engaging arm may be secured to a wall or similar support. AThe wall-engaging arm I I is provided adjacent ythe Yupper end of the panel I2 with a slot I4, the purpose of which will be referred to hereinafter, and at its; upper end the wall-engaging arm II is provided with a forwardly-extending shelf-engaging resilient finger I5 which may be vof any 'desired shape but is preferably embossed, as shown, to provide aV gcenter panel I8 and a pair of downwardly ex- ,tending lugs I'I disposed on opposite sides of the its opposite end the shelf-supporting arm |8 isv provided with a tab or finger 22 (Figs. '1 and 8) which extends through thesloii 4 in the wallf engaging arm and is adapted to be spotvwelded or otherwise secured thereto as indicated at 23 in Figs. 7 and 8. r

shelf-supporting arm I8 and forced rearwardly until its rear edge portion is clamped between finger I5 and the shelf-supporting pad 26, the rear edge of the shelf will ride up the sloping surface of the pad 26 and gradually flex the spring arm i5 so that there will be no sudden shock or jal` tending to chip the rear edge, of the shelf. The same is true when they shelf is removed by pulling it forwardly from the shelf brackets and consequently chipping or breakage of the rear edge of a glass shelf is eliminated.

Extending between the lower portion of the wall-engaging arm and the front end portion of the shelf-engaging arm I8 is a diagonal bracing arm 24f which; a'sfsh'own, ispreferably in the form of a wire loop, one end of which'is welded or otherwise suitably. secured to the panel. l2 of the wall-engaging arm4 'Atitsupper end the loop 2liA is provided witha horizontally extending portion 25.. (Fig. 1.?)V which rests within Athe embossment 2| and is adaptedatolbe welded or otherwise suitably secured `therein, thus providing a strong and rigid shelf structure.

While shelf bracketsconstructed. as heretofore described are not limitedtoiusewith glass shelves butv may. be" employedz'for supporting'shelves formed ofA wood, molded. plastic materials or the like, certain features of the present invention are particularly. applicable. to Iglass shelves.` in `order to avoid; breakage "and: chipping thereof when assembling the shelf on the bracket. These fea-i tures of the invention-*reside-.inthe provision of a. nonrnetallicresilient shelfesupporting pad adjacent the rear end of the-.slielfesupporting arm, which pad may-be of-the.formshownin Fig. e.
