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.

Abstract: A collapsible table includes a tabletop having a center leaf, intermediate first and second end leaves. First and second pairs of support arms and support legs are pivotally mounted about an axle depending from the center leaf. The arms and legs of each pair are pivotal about the axle in opposed directions between a first collapsed position and a second functional position. The support arms at the second position position the leaves attached thereto in a coplanar relationship with the center leaf. At their functional position the support legs provide underlying support to the center leaf. Slots in the arms and legs engage a key depending from the center leaf so as to maintain the arms and legs at their functional positions. A spring bias on the axle further urges the slots against the key with the weight of the center leaf urging the key into the slots. Upon lifting the center leaf the keys disengage the slots which allows the arms and legs to pivot to their collapsed positions.

The lock bar bends to exert locking force in both the unfolded and folded positions of the table legs.

Abstract: A locking mechanism (10) that provides for locking a table leg (12) in an extended position and a folded position. The locking mechanism is mounted to the underside of a table (14) and is comprised of a bar (90) that is pivotally mounted between right and left flanges (20, 22) of the locking mechanism. The bar has a channel (112) that provides for laterally adjusting the table leg to compensate for uneven floor contours. A first locking member (136) is controlled by an overcenter lever (126) to seat a locking rod (138) in a locking channel (102) provided on one side of the bar, opposite the lever. This provides for locking the bar and the table leg in the extended, use position. Releasing the lever enables the lever to move out of the overcenter position so that the locking rod moves out of the locking channel and the bar is able to pivot into the folded position. A second locking member (150) then engages an enlarged portion (106) of the bar and serves to block the bar in the folded position.
