A composite leg-support with high loadability having a tubular vertical shank (4) and legs (1) which are releasably affixed to the shank and extending essentially horizontally and radially therefrom. The ends of the legs (1) pointing toward the center of the shank (4) have extensions (2, 3, 13, 18)
A composite leg-support with high loadability having a tubular vertical shank (4) and legs (1) which are releasably affixed to the shank and extending essentially horizontally and radially therefrom. The ends of the legs (1) pointing toward the center of the shank (4) have extensions (2, 3, 13, 18) which protrude into the interior of the shank (4), through openings (5) distributed along the periphery of the shank (4), and they engage in a force-locking manner with profiled discs (6, 10, 15) contained in the shank (4). The discs (6, 10, 15) are pressed towards one another by means of screw (11) extending along the longitudinal axis of shanks (4) and it is accessible from the lower end portion thereof.

A composite leg support having a vertical shank and at least three legs or the like arranged approximately perpendicularly to the longitudinal axis of the shank, extending radially thereto, and connected to the shank (4) in a force-locking but releasable manner, the end of each leg connectable to said shank being provide with upper and lower claw-like arresting means (2, 3, 13, 18, 18′, 18″), which are locked to the shank in position by means of an upper disc (6, 22, 52) and a lower disc (10, 15, 25, 53) or the like, these discs being provided with threaded bore means (8, 11, 21, 51, 56) for moving to and from each other thereby entering respectively into and out of engagement with upper and lower arculated grooves (14) formed by said arresting means (2, 3, 13, 18, 18′, 18″) via circumferential flanges (7, 23, 26, 56) or the like, said arresting means indirectly forming at least both sides of said grooves for absorbing outer loads in this area in a shape-force-locking manner, at least one circumferential edge of which being inclined in relation to said axis, the dimensions of at least one of said flanges being greater than those of said arculated grooves (14) in order to insure tight fitting and to compensate for material wear; the end of the legs (1, 19) facing the shank (4, 31) being formed with a curved concave surface in compliance with the curvature of the shank (4) so that in the assembled state said concave surfaces interact with the shank (4, 31), the arresting means (2, 3, 13, 18, 18′, 18″) and the discs (6, 10, 15, 22, 25, 52, 52) in the shape-force-locking manner; and a flange (17) is provided on the lower part of the curved surface of the legs (1, 19), the width of which corresponds to the wall-thickness of the shank (4), and said flange (17) bearing against the lower end of the shank (4) of the leg-support in the assembled state.
