Abstract: A folding table is comprised of a table top and frame of side rails, and includes at each corner formed by the side rails, a further rail attached to the underside of the top forming a channel with one of the side rails. A leg is pivotally attached at each corner on an axis perpendicular to the opposing walls of the channel formed. A locking means is carried within a recess of the further rail which, when a leg is unfolded to its extended position, will be effective under spring loading, to provide a bearing against the leg for locking it into extended position. Pressure on the locking means to force it into the recess, releases the leg for folding. When the legs are in the folded or unfolded position, the locking mechanism is completely hidden.
