9 A m N 9 m. 6 8N m 2 2 e W U. 0 l M F m -R. E. BAILEY CORNER BRACE! Filed March 6, 1953 llll I Feb. 16, 1954 Patented Feb. 16, 1954 UNITED STATES ATENT OFFICE 2 Claims. (01. 311-113) 1 This invention relates to joints and more particularly to a corner brace for effecting furniture joints.

A primary object of this invention is to provide a corner brace which will secure the rails and a leg of a table, chair or other article of furniture to each other and which will require but a single fastening element to effect such securement.

Another object of this invention to provide a corner brace which will maintain the side rails of an article of furniture securely in place and prevent horizontal shifting thereof.

Another object of this invention is to provide a joint structure which incorporates a novel corner brace secured by means of a lag screw which may be tightened at any time to maintain the original rigidity of the joint.

Another object of this invention is to provide a corner brace having vertical flanges engageable with the side rails of a table or the like which will prevent longitudinal shifting of these rails.

Another object of this invention is to provide a corner brace having a horizontal flange engaged with a table leg and underlying the side rails to relieve the fastening screw of downward forces.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective View showing one leg and a pair of intersecting side rails interconnected by means of the novel corner brace;

Figure 2 is a perspective view of the brace on an enlarged scale;

Figure 3 is a vertical section taken substantially along the plane of section line 33 of Figure 1 and showing the details of the corner brace mounting on an enlarged scale;

Figure 4 is a perspective view of a portion of a table or the like in inverted position showing the use of the novel corner brace; and

Figure 5 is a horizontal section taken substantially along the plane of section line 55 and showing details of the inter-engagement between the corner brace and the leg and side rails of the article of furniture.

Referrin now more particularly to the drawings, reference numeral Hi indicates the leg of a table, chair or other article of furniture and reference numeral 12 indicates a pair of intersecting side rails whoseends abut against adjacent surfaces of the leg.

Ordinarily, the joint between the leg and the rails is effected by the use of screws, nails, burrs or the like and such securernent not only necessitates the individual fastening of the various elements to each other, but is also time consuming and the joint thereby formed is subject to forces during the use and abuse of the chair or other article of furniture which will loosen the joint formed, such joint being incapable of retightening.

Such joints are replaced by the novel structure hereinafter set forth and which includes a corner brace designated generally by the reference character Hi, the main portion of which is formed by a rectangular plate it having laterally bent vertical edges forming vertical flanges lit, a lower laterally bent edge forming a flange 26 and an upper edge laterally bent to form a mounting flange 22. The main portion of the plate is provided with an opening or aperture 2t for the re ception of a lag screw 26 and the upper flange 22 is provided with openings 25 to receive fastening screws 38. The vertical flanges i8 and the lower flange it! are bent to extend in one direction and the upper flange 22 is bent to extend in an opposite direction, for purposes presently apparent.

Referring now more particularly to Figures 3-5, the plate is disposed to extend between the angle formed by the intersecting side rails and the side rails are provided with angularly extending grooves 32 adjacent their ends which receive the vertical flanges H3. The lower flange 2!] engages against and underlies the under surface of the side rails and a portion thereof extends inwardly within a horizontal groove 34 extending transversely of one edge of the leg It, as shown most clearly in Figure 3. Table top or chair seat tilt is maintained in position by virtue of the upper flange engaging its under surface and being secured thereto by the fastening screws 36. Lag screw 25 urges the plate toward the leg and the side rails are wedged thereagainst in response to the effect created by the engagement of the vertical flanges in the angular slots.

It will be readily appreciated that since the lower flange 2i) underlies the side rails and engages within the groove in the leg, the lag screw will be relieved of any vertical forces imposed upon the article of furniture and the engagement between the vertical flanges l8 and the side rails will prevent longitudinal shifting or dislodgement of the latter.

By utilizing the novel corner brace, a joint may be quickly and efiectively assembled and disassembled in a minimum of time. The flanges operate not only in the manner intended but also serve to reinforce the brace assembly.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling Within the scope of the appended claims.

What is claimed as new is as follows:

1. A corner brace comprising a vertical plate member of generally rectangular configuration, said plate having its opposed side edges laterally bent to present vertical side flanges, the lower edge of said plate being laterally bent in the di- I'ection of said vertical side flanges to present a horizontal lower flange, the upper edge of said plate bein laterally bent oppositely :of said lower flange to present an upper horizontal flange; said lower flange being wider than and projecting beyond the vertical edges of said side flanges a dis- 4 tance substantially equal to the width of the same.

2. The combination of claim 1 wherein said vertical plate member is provided with an aperture for receiving a fastening element, said upper horizontal flange being provided with a pair of spaced apertures for the reception of fastening elements.
