Abstract
Abstract The present invention utilizes a leg attachment bracket of novel design for securely but removably attaching legs to table tops having pressboard cores. This bracket, which can be molded in one piece from plastic, is provided with perimetric flanges united by a recessed horizontally-extending web. The top edges of the flanges are in planar alignment and bear against the bottom surface of the table top for adhesively bonding thereto. Locator opening are provided in the bracket through which screws can extend for initial attachment during the setting of the adhesive. The top side of bracket provides a plurality of sockets surrounding openings in which T nuts can be seated. The T-nuts are accessible from the bottom side of the bracket. This permits the legs to be releasably connected to the top, while the bracket is permanently attached.
