Tubular fold-away legs for support surfaces which includes a joint, which is made up of an element for coupling to the tubular body and an attachment element to said support surface, the legs being mobile between a first closed non-operative position and a second open operative position, tilted by an angle with respect to the support surface. The joint is equipped with elastic locking device to secure it in either the non-operative or operative positions and with a stable attachment device when in the operative position, as well as matching tilted centering surfaces.

The invention claimed is: 1. Tubular fold-away legs for a support surface, each comprising a joint (13), comprising an element for coupling with a tubular body (15), a tubular body (12) capable of being secured to the element for coupling with a tubular body (15), and an attachment element attachable (16) to said support surface (14), said legs (10) being mobile between a first closed non-operative position (A) and a second open operative position (B), tiltable by an angle ({acute over (α)}) with respect to said surface (14), said joint (13) being equipped with elastic locking means (25) of said two non-operative (A) and operative (B) positions and with stable attachment means (23, 23A and 26) of said operative position (B), comprising matching tilted centering surfaces characterized in that said elastic locking means (25) consists of an elastic U-bolt comprising a central pressing surface (32) and two side arms (31) carrying engagement elements (33) housed in symmetrical through seats (30) of said element for coupling with the tubular body (15) and capable of engaging in pairs of seats (24a) or (24b) of said attachment element (16). 2. Legs according to claim 1, characterized in that said element for coupling with the tubular body (15) is a sleeve, suitable for being inserted with interference in said tubular body (12). 3. Legs according to claim 2, characterized in that said sleeve (15) is equipped with a perimetric collar (36), suitable for constituting an abutment surface (37) for the piling of support surfaces (14) with said legs (10) in non-operative position (A). 4. Legs according to claim 1, characterized in that said attachment element (16) attachable to said support surface (14) is a perforated attachment plate (18). 5. Legs according to claim 1, characterized in that said attachment element (16) comprises a guide wall (20) for the rotation of said element for coupling with the tubular body (15) with respect to said support surface (14). 6. Legs according to claim 5, characterized in that said guide wall (20) has a beveled profile (22) in a plane of rotation (11) of said legs (10). 7. Legs according to claim 5, characterized in that said stable attachment means consists of two wedge-shaped elements (23) protruding laterally from said guide wall (20) and of tilted inner surfaces (26), matching said wedge-shaped elements (23) of said element for coupling with the tubular body (15), between said elements (23) a curved surface (23A) being foreseen. 8. Legs according to claim 1, characterized in that said central pressing surface (32) is concave. 9. Legs according to claim 1, characterized in that said engagement elements are trapezoidal fins (33) which ate symmetrical with respect to a plane of rotation (11). 10. Legs according to claim 1, characterized in that said through seats (30) are equipped with tilted planes (34) matching outlet edges (35) of said engagement elements (33). 11. Legs according to claim 1, characterized in that said element for coupling with the tubular body (15) and said attachment element (16) to a support surface (14) can be made both from metal and from plastic. 12. Legs according to claim 1, characterized in that said angle of inclination ({acute over (α)}) is a right angle. 13. Legs according to claim 1, characterized in that the joint (13) and relative components are all contained within the respective leg.
