ABSTRACT:
A hinge-latch mechanism mounts an extension leaf to a table for movement between extended and storage positions. A pair of guide rails, mounted to the table, support a flat hinge plate for sliding movement along the undersurface of the table while an extension leaf is pivotally connected to one end of the hinge plate for rotation between the extended and storage positions. A latch mechanism is provided to lock the leaf in the extended position.
