The invention is an improved leg folding mechanism for a folding table. The leg has a T-shaped top end and carries a pair of disc shaped followers on the ends of the T arms. These followers are arranged to travel in a pair of parallel guide channels when the leg is folded and erected. The leg itself carries an "axle" which protrudes therethrough on both sides. Each of a pair of elongated compression members is connected at one end to one end of the axle and the other end of each compression member is pivotally connected to the table top. Each of a pair of tension links is also pivotally connected to the table top at one end and to the axle by a slot in the other end. A latch secures the top end of the leg to the table top when erected. The dimensions of the compression members and tension links are so selected that, when the table is erected, the tension links are under tension and this tension force is applied directly to the compression members, thereby keeping them under compression. This results in a table of exceptional rigidity. |
