1 Claim, 7 Drawing Figures CORNER BRACKET FOR FURNITURE CASE BACKGROUND AND SUMMARY OF INVENTION In the past, corner braces for the interior parts of furniture have consisted of triangular blocks. Normally, these were made up of a chip core of reprocessed wood plus veneer facings on the sides. The real recommendation of the prior art brackets was their low cost, being essentially a salvage item. The low cost compensated for the lack of precision, strength, etc. Increasingly, of late, factories are eliminating the use of veneer facings, so there is not available the material necessary to provide these side facings. Attempts to use the chip core alone has resulted in splintering, loss of support and the like. This has become particularly critical when taller and taller furniture pieces are being made.

According to the invention, a sturdy, precise corner bracket is provided through the use of aunitary strap of metal with the end portions folded into upstanding flanges at 45 and with suitable bracing ribs installed in the strap. Through the use of the novel corner brace of the invention, the advantages of relatively low cost of the prior art brackets is achieved, yet with increased or additional advantages insofar as performance is concemed.

DETAILED DESCRIPTION OF THE INVENTION The invention is described in conjunction with an illustrative embodiment in the accompanying drawing in which:

FIG. 1 is a fragmentary perspective view of a fumiture piece (here a dresser) showing the inventive corner brackets installed and depicted in phantom line;

FIG. 2 is a fragmentary sectional view taken along the line 2-2 of FIG. 1;

FIG. 3 is a fragmentary sectional view taken along the line 3-3 of FIG. 2;

FIG. 4 is a perspective view of the corner bracket employed in connection with the showings in FIG. 1-3;

, FIG. 5 is a fragmentary sectional view taken along the line 5-5 of FIG. 4; and;

FIG. 6 is a perspective view of a modified form of the invention;

FIG. 7 is a fragmentary sectional view taken along the line 7-7 of FIG. 4.

In the illustration given and with reference first to FIG. 1, the numeral 10 designates generally a furniture piece here illustrated. as a dresser. As such, the dresser includes a frame 11, a top 12, and drawers l3 and 14.

The frame 11 is defined in part by means of vertical frame members as at 15 (see the extreme right hand portion of FIG 1). Additionally, the frame 11 includes parting rails as at 16, which are essentially horizontal members interconnecting the frame. The inventive bracket, generally designated 17, interconnects in a bracing fashion the vertical frame member 15 and the horizontal parting rail 16. As indicated in FIGS. 1-3, a plurality of the corner brackets are advantageously employed.

The corner bracket 17 is seen in enlarged perspective view in FIG. 4, and is seen to consist essentially of a unitary, substantially rigid, member such as a metal strap such as would be constructed of between 14 to gauge steel.

The strap constituting the corner bracket 17 is seen to have been formed in three discrete portions. The flat intermediate portion 18 has, at each end thereof. end portions 19 and 20, each of which is orthogonally re lated to the intermediate portion 18. These in essence are formed by folding the end portions of the strap at right angles to the intermediate portion, but along lines that are 45 relative to the length of the intermediate portion 18. Thus, the end portions 19 and 20 are in themselves orthogonally related.

The strap or blank from which the comer bracket is formed is equipped with ribbing generally designated 21 which is found primarily in the intermediate portion. More particularly, a first rib 22 is provided which extends longitudinally of the bracket 17 and, while primarily located within the intermediate portion 18, has end portions as at 23 and 24 which terminate within the end portions 19 and 20, respectively.

As can be seen clearly in FIG. 4, the ribbing 21 also includes transverse ribbing as at 25 and 26 which serves to strengthen the bracket in a plane normal to the plane strengthened by the longitudinal rib 22. It will be seen that the transverse ribbing 25 and 26 includes two ribs which are angularly related to each other.

In the illustration given in FIG. 4, the bracket 17 has its end portions 19 and 20 equipped with a plurality of screw receiving openings as at 27 (see the upper left hand portion of FIG. 4). Each of the end portions 19 and 20 in the face thereof confronting the frame member or parting rail, as the case may be, is equipped with an outstanding annular flange as at 28 (see FIG. 7) which serves to enter into biting engagement with the surface to which the bracket 17 is secured.

Additionally, each of the end portions 19 and 20 is equipped with projections as at 29 (see FIG. 5) on the above-mentioned confronting surfaces those faces of the end portions which abut and are in contact with the frame members. The projections 29 are advantageously achieved by dimpling the end portions 19 and 20 this resulting in the circular depressions as at 29' seen in the upper left hand portion of FIG. 4. It has been found advantageous to utilize the projections 29 but to restrict their outward extension to slightly less than the outward extension of the annular flange 28 the difference in projection being exaggerated somewhat in the showing in FIG. 5.

Still further, advantageous stabilization and reenforcement is achieved through the use of gussets as at 30 in the upper portion of FIG. 4. Each gusset extends between the intermediate portion 18 and the associated end portion 19 or 20 as the case may be, with the gussets being provided as integral portions of the brackets 17 (see FIG. 5, for example).

A modified form of the invention is seen in FIG. 6 wherein the bracket is designated generally by the numeral 117. The various parts hereinbefore described are present, with the principal difference being in the openings in the end portions 119 and 120 for the purpose of securing the bracket to the orthogonally related frame member. In the illustration given in FIG. 6, a pair of slots 131 and 132 are provided for the receipt of a staple 133 (see the lower right hand portion of FIG. 6). A plurality of sets of staple-receiving openings are provided in each end portion of the structure illustrated in FIG. 6. Also, the number of projections could be reduced as evidenced by the lesser number of dimples 129' provided in the structure seen in FIG. 6. However,

a slightly different arrangement of the dimples 129 would permit the use of a larger number without departing from the spirit and scope of the invention.

1 claim:

1.- A corner bracket for a furniture case comprising a unitary substantially rigid member having a substantially flat intermediate portion and upstanding integral end portions disposed generally orthogonally relative to the intermediate portion, the end portions being orthogonally related to each other and so disposed as to bear against a horizontal parting rail and a vertical frame member, respectively, a plurality of gussets interconnecting said intermediate portion with said end portions, said intermediate portion being equipped with reenforcing rib means, said rib means including a first rib extending generally longitudinally of the member and terminating within the end portions, said rib means also including transverse ribbing to strengthen said member in a plane normal to the plane strengthened by the longitudinal rib, said end portions being equipped with a plurality of screw receiving openings, each opening on the side of the end portion adapted to confront said parting rail and said frame member being equipped with an outstanding annular flange for biting engagement with said parting rail or frame member as the case may be, said end portions also being equipped with projections on the same surface as is equipped with said annular flanges, said annular flanges projecting outwardly from said surfaces slightly greater than said projections.
