Abstract
Abstract A leg attachment assembly connecting a furniture leg to an article of furniture for providing maximum rigidity and strength to the leg and eliminating wobbling of the assembled furniture. A bracket plate overlies and is secured to the top end of the leg and underlies and is secured to the undersurface of the article of furniture. A depending support bracket is disposed in a recess in the inner corner of the leg and is secured thereto so that it fits flush into the leg thereby bracing the leg. The plate is attached to the leg and to the article of furniture by employing threaded steel bars that are threaded into a steel locking bar mounted in the leg and in the article of furniture respectively.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
A leg attachment assembly for securing legs to an article of furniture comprising a plate engaging the undersurface of the article of furniture and being disposed in overlying engagement with the top edge of the leg, means securing the plate to the article of furniture, fastener means extending through apertures in the plate for securing the plate to the top edge of the leg, depending means on said plate engaging the inner surface of the leg, and means securing the depending means to the inner surface of the leg for bracing and rigidifying the leg, said depending means including an angled bracket integral with the plate with the legs of the angled bracket engaging adjacent surfaces of the inner corner of the furniture leg, said means securing the plate to the article of furniture including a plurality of screwthreaded fasteners extending through apertures in the plate, and a locking bar in the article of furniture threadedly engaging the fasteners for fixedly securing the plate to the article of furniture, said fastener means securing the plate to the leg including threaded fasteners extending through said apertures in the plate, and locking bar means in the leg screw-threadedly receiving the fasteners for securing the plate to the leg.
Claim 2
Dependent Claim
206 words
A leg attachment assembly for securing legs to an article of furniture comprising a plate engaging the undersurface of the article of furniture and being disposed in overlying engagement with the top edge of the leg, means securing the plate to the article of furniture, fastener means extending through apertures in the plate for securing the plate to the top edge of the leg, depending means on said plate engaging the inner surface of the leg, and means securing the depending means to the inner surface of the leg for bracing and rigidifying the leg, said depending means including an angled bracket integral with the plate with the legs of the angled bracket engaging adjacent surfaces of the inner corner of the furniture leg, said means securing the plate to the article of furniture including a plurality of screwthreaded fasteners extending through apertures in the plate, and a locking bar in the article of furniture threadedly engaging the fasteners for fixedly securing the plate to the article of furniture, said fastener means securing the plate to the leg including threaded fasteners extending through said apertures in the plate, and locking bar means in the leg screw-threadedly receiving the fasteners for securing the plate to the leg.
Claim 3
Dependent Claim
35 words
The structure as defined in claim 1 wherein said plate and depending bracket are of unitary cast material with the plate including a projection thereon overlying the top edge of the leg and conforming therewith.
Claim 4
Dependent Claim
204 words
In combination with a tabletop haviNg a locking bar inserted therein and a depending leg at the corner thereof having a locking bar inserted therein in spaced relation to the top edge thereof, an attaching plate underlying the tabletop, threaded fasteners extending through the plate and threaded into the locking bar in the tabletop, said plate including an extension overlying and conforming with the top edge of the leg, threaded fasteners extending through apertures in the extension and threaded into the locking bar in the leg for rigidly securing the leg to the tabletop, and a depending supporting bracket on the undersurface of the plate, said bracket being right-angular in configuration, said leg including an inner corner having a recess therein conforming with and receiving the bracket in flush relation therewith, and fasteners extending through the legs of the bracket into the table leg for securing the leg rigidly in position thereby providing a table with the legs secured thereto without the use of stretchers or aprons extending between the upper end portions of the legs to provide greater comfort and space for crossing and uncrossing the legs when positioned in a chair with the person''s legs occupying the chair extending under the table.
Claim 5
Dependent Claim
204 words
In combination with a tabletop haviNg a locking bar inserted therein and a depending leg at the corner thereof having a locking bar inserted therein in spaced relation to the top edge thereof, an attaching plate underlying the tabletop, threaded fasteners extending through the plate and threaded into the locking bar in the tabletop, said plate including an extension overlying and conforming with the top edge of the leg, threaded fasteners extending through apertures in the extension and threaded into the locking bar in the leg for rigidly securing the leg to the tabletop, and a depending supporting bracket on the undersurface of the plate, said bracket being right-angular in configuration, said leg including an inner corner having a recess therein conforming with and receiving the bracket in flush relation therewith, and fasteners extending through the legs of the bracket into the table leg for securing the leg rigidly in position thereby providing a table with the legs secured thereto without the use of stretchers or aprons extending between the upper end portions of the legs to provide greater comfort and space for crossing and uncrossing the legs when positioned in a chair with the person''s legs occupying the chair extending under the table.
Claim 6
Dependent Claim
66 words
The combination as defined in claim 3 wherein the plate, extension and depending supporting bracket are of unitary one-piece construction, the junction between the plate and bracket being provided with a rounded, thickened gusset area reinforcing the bracket and plate, said tabletop having a peripheral edge terminating flush with the lower surface of the plate thereby concealing the plate and eliminating depending projections under the tabletop.
