ABSTRACT:
A folding leg mechanism for a table is adapted to be releasably locked in a firm, stable position as the leg portion thereof is swung down to extended position from retracted position against the underside of the table top. A longitudinal slot extends through at least one side of the leg and has its longitudinal axis in substantial alignment along the leg with the pivot axis about which the leg swings. A pin extends outwardly through the slot and is adapted for movement along the longitudinal axis of the slot. Spring means are provided for biasing the pin toward that end of the leg which is attached to the table. A trackway is positioned at the side of the leg from which the pin extends, so that the pin rides on and along the trackway as the leg swings between its retracted and extended positions. Abutment means are provided with which the leg makes contact when it is moved to its extended position. An upwardly extending, pin-receiving recess is positioned in the trackway so that the pin will enter it as the leg makes contact with the abutment means. As the pin enters the recess, a wedging action takes place, locking the leg in firm contact with the abutment means.
