Abstract: A support leg (16) includes an insert (20) within a tubular upper portion (18). Threaded engagement is made between the threaded opening (22) in the insert (20) and a stud (14) which is welded at its upper end to an overhead structure (10). The tubular portion (18) extends through an opening in the small end (34) of a conical brace member (32). The small end (34) of member (32) is welded (38) to the member (16). A large diameter upper end (36) of brace member (32) extends axially outwardly beyond the end (42) of member (16). Rotation of member (16) relative to the stud (14) tightens the screw joint (14, 22) and forces the upper end (36) of brace member (32) into tight contact with the overhead member (10). The weld (44) is harder than the member (16), resulting in a galling of the upper end ( 42) of member (16), during the rotation. This galling makes a tight contact fit between end (42) and weld bead (44).

The positioning of the legs is controlled by an actuator telescoped upwardly into the open bottom end of a vertical actuator tube mounted under the cage. The actuator is normally positioned in an extended position projecting downwardly beyond the bottom ends of the legs when they are in their collapsed position. Rigid coupling links are pivotally connected between the actuator an support legs such that retraction of the retractor upwardly into the tube raises the proximate ends of the links upwardly driving the lower end of the support legs radially outwardly to their support positions.

Abstract: A table leg mount for attaching a table leg to a table top includes a mounting member which has an integrally formed screw shank. The mounting member is attached to the table top by a mounting plate and projects into a hollow portion on the upper end of the table leg. The screw shank passes through a hole in a resilient gripping member and engages a threaded portion on the table leg. Tightening the table leg onto the mounting member forces the gripping member to bear against a conical portion on the mounting member and to also bear against the inside of the hollow portion of the table leg thereby creating a rigid connection between the table leg, the mounting member and the table top.
