Abstract
Abstract A locking connector, primarily intended for folding furniture such as tables and chairs, which includes a mounting plate for attachment to the flat undersurface of a table top or chair seat and having a pair of side flanges for mounting an essentially channel-shaped fixture. In one embodiment, the connecting web supports a screw-threaded dowel to receive a round furniture leg; and in another embodiment, one flange and a portion of the connecting web is extended for attachment to a square furniture leg. The mounting plate carries a latching lever and the fixture is provided with a cooperating surface for locking the fixture in perpendicular relation to the mounting plate.
