2 Claims.

This invention relates to improvements in supporting brackets such as used with drop shelves and the like which are mounted to adapt the shelf to occupy an inoperative position close be- 5 side its support and to be moved to and supported in an operative position in which it projects out from the support. Such shelves may be provided, for example, on le cabinets or other articles of furniture with the shelf mounted so as to fold to a position against the front of the cabinet in which it will not project out therefrom to an objectionable extent, but is adapted to be raised and supported in an operative position in which it projects forwardly from the front of the cabinet. My improved bracket, however, is adapted for other uses.

One object of my invention is to provide a shelf-supporting bracket which is hidden behind the shelf in the folded position of the latter, gonand which, when the shelf is moved to its operative position, automatically moves to supporting position and supports the shelf.

Other objects are to provide in association With a drop shelf, a spring-actuated bracket which is hinged to fold toward its support to allow the shelf to drop, and to automatically swing beneath and support the shelf when the latter is raised for use; to provide a desirable spring-actuated bracket of simple and inexpensive construction in position or removed; which is provided with a spring that acts both to swing the bracket from its folded to its supporting position, and also to prevent unintentional disengagement of the bracket from its support, while nevertheless allowing ready detachment of the bracket therefrom; and to provide supporting means having the other features of improvement and advantage hereinafter described and set forth in the claims.

In the accompanying drawing:

Fig. 9 is a section through the shelf hinge on line 9 9, Fig. 2.

Referring to the drawing, I0 represents .a shelf which, as shown, consists of a sheet metal plate bent to form downturned stiffening and finishing flanges Il at the side and end edges of the shelf, and is mounted on the front of a cabinet or other support l2, as by hinges, so that the shelf is adapted to be swung or moved from the position shown in Figs. l and 5, in which it hangs vertically against the front of the support I2 to an operative position in which it projects out forwardly from the support I2. I3 indicates one of the shelf hinges, of which two may be provided, one adjacent each end of the shelf. An ordinary flat-leaf hinge is shown having one leaf welded to the inner face of the reary ange of the shelf and the other leaf fastened by screw bolts I4 to the support I2. The shelf could be constructed and mounted to drop or fold in any other suitable way.

Mounted on the support I2, in a position betive position, is a shelf-supporting bracket I6. This bracket, as shown, is formed by a substantially triangular metal plate hinged at its upright, rear edge portion on upper and lower hinge lugs Il and I8 projecting forwardly from the support l2. As shown, these hinge lugs are formed by the outbent upper and lower ends of a metal bar I9 which is stationarily secured, preferably by screw bolts 20, on the upright front wall of the support l2. A downwardly projecting pivot stud 2| formed at the lower end of the bracket IB extends through a circular hole in the bottom lug I8, and a pivot stud 23 formed at the upper end of the bracket extends upwardly through a cir cular hole in the upper lug Il'. The upper pivot stud is preferably formed by slotting the upper edge of the bracket at 24 and is longer than the bottom stud 2l so that when the bracket is in connection with its hinge lugs, it is adapted to be shifted upwardly in the pivot holes of the lugs until the bottom stud is disengaged from the bottom lug. The lower end of the bracket can then be moved laterally from over the bottom -hinge lug and the bracket then lowered to disengage its upper stud from its hinge lug and thus neath the shelf when the latter is in its opera- 35V, the face of the support l2.

beneath the upper hinge lug, with one end of the spring wire hooked into a hole 26 in the bracket and its other end hooked over the edge of the bar i9. This spring, bearing at its opposite ends x against the bottom of the slot 24 and against the upper hinge lug il, acts to press the bracket. downwardly and retain the lower pivot stud in the' hole of the lower hinge lug, thereby preventing unintentional disengagement of the stud from the.. l.; lug, but the spring can be compressed endwiseby lifting the bracket to allow the disengagement of the bracket from its supporting hinge lugs,v as before mentioned. In addition, with the-spring arranged as shown and described, when the. Q bracket i6 is swung from its outwardly projecting supporting position back toward the support I2, the spring will be strained or placed under tension, and when the bracket is released, the spring will swing the bracket from its folded position beside 251 the support to its supporting position in which it' projects outwardly from the support.

The bracket is provided with a stop 2l adaptedto prevent the bracket from swinging beyond its operative position, substantially perpendicular to This stop is preferably formed by an L-shaped metal piece welded to one side of the rear portion of the bracket, with its rear end projecting laterallyin rear of the rear edge of the bracket in position to strike the front 35' ici the hinge bar i9. when the bracket is vin its out-jwardiy projecting or supportingA position, see Fig. 8, and thus prevent movement of the bracket by its spring 25 beyond this position.

Assuming the parts to be in the folded or inop- Oferative position shown in Figs. 1 and 5, the shelf will hang down on its hinges close to the front face of the support l2?, and by engaging the front end of the bracket it, willhold the latter back in the position shown in Fig. l. When it is desired to 45 vfuse the shelf, it is simply lifted or swung up from its hanging position to a horizontal, forwardly.

projecting position, and this movement of the shelf frees the bracket E6 and permits the same to be swung forwardly by its spring 25 into support- 5Oeing position beneath the shelf so that the shelf will be supported by bearing on the upper end of the bracket. sisting of a U-shaped metal strip having end flanges welded on the underside of the shelf, prov5e/jects downwardly from the shelf -in position to bear upon the outer end portion of the bracket l 6 when the latter is in its supporting position. This Preferably, ay bearing piece 28 con- I claim as my invention:

'"l. The combination with a hinged shelf, of a supporting bracket therefor provided at its inner end with upper and lower pivot studs, upper and lower, stationary hinge lugs having holes in which said studs are movable axially and are also rotatable to allow the'bracket to swing to and from an operative supporting position, one of said studs beingsuiiciently longer than the other to allow enoughaxial movement thereof in its hinge lug for disengagementv of the other stud from its hinge lug, a spring which is coiled about said first mentioned stud and bears at opposite ends against said bracket and hinge lug, said spring yieldingly opposing such axial stud-disengaging movement of the bracket and also acting on said bracket to swing it to said operative position, and means comprising a part on said bracket `and a xed stop arranged to be engaged thereby to prevent the bracket from being swung by said spring beyond the shelf-supporting position.

2. The combination witha stationary support having upper and lower hinge lugs with vertical holes therethrough and a hinged shelf, of a supporting bracket for the. shelf consisting of a flat metal plate shaped to form a downwardly projecting hinge stud at its lower inner corner, and a slot in its upper edge forming an upwardly projecting hinge stud at the upper inner corner of the bracket, said studs being axially movable and rotatable in the holes of said lower and upper lugs, and said upper stud being suiiciently longer than the lower stud to allow enough axial movement of the upper stud in its hinge lug to disengage the lower studv from its` hinge lug, a spring which is coiledabout said upper stud with its opposite ends engaging said bracket and said support and acting to swing the bracket to a shelf-supporting position projecting outwardly from said support, said spring also bearing at opposite ends against the bottom of said slot and the adjacent hinge lug and yieldingly opposing the axial disengaging movement of the bracket, and parts on said bracket and supportarranged to engage to prevent the bracket from being swung by said spring beyond said shelf-supporting position.
