ABSTRACT:
A folding table leg apparatus for a table including one or more legs operable between an extended and a folded position. The folding table leg apparatus associated with each of the legs includes a pair of side supports which are connected to the underside of the table top. Each of the side supports includes a receiving notch which receives a cross bar connected to the upper end of the table leg when the table leg is in the extended position. A hinge bracket and a folding plate are connected between the pair of side supports and the table leg to permit the table leg to move between the folded and extended position. The table leg is pivotable about a lower leg pivot axis which is spaced from the upper end of the table leg, such that when the table leg is in the folded position, the distance which the table leg extends from the folding apparatus is less than the entire length of the table leg. The folding apparatus further includes a locking mechanism that secures the cross bar in the receiving notches when the table leg is in the extended position. The locking mechanism includes a pair of locking brackets joined by a connecting rod such that the locking brackets are operatively joined. As the folding table leg moves from the folded position to the extended position, the cross bar interacts with a cam surface on each of the locking brackets to rotate the locking brackets away from the receiving notches thereby allowing the cross bar to be received in the receiving notches formed in the side supports. A torsion spring holds the locking brackets in a locked position to securely hold the cross bar in the receiving notches when the table leg is in its extended position.
