Filed: 1979-03-21
Abstract: Anchor apparatus for installation in an opening in a floor to anchor a cable includes an expandable outer shell (10), an outer wedge (18) disposed in the shell and having wedge-shaped projections (22) engaged with the inner wall of the shell, and a rotatable inner wedge (32) below the outer wedge engaged by a lower cable attachment member (44) for attaching a short length of chain (54) extending upwardly through the shell (10) and the wedges (18 and 32). A cable to be tensioned is attached to the short length of chain which otherwise is secured to a cover plate (64). Tension on the cable urges the inner wedge upwardly against the outer wedge which, in turn, is wedged in the interior of the shell to forceably expand the walls of the shell radially outwardly to embed the shell in the floor. The inner wedge is rotatable axially relative to the outer wedge between a first position aligning projections (34) with wedging seats (40), in which a wedging force is applied to the outer wedge in response to tensioning of the cable to wedge it securely in the shell, and a second position, aligning projections (34) with axial clearance grooves (38), which allows removal of the inner wedge and the short length of chain from the outer wedge and the shell. A reinforcing ring (58) welded into the top of the shell has grooves (62) which continue the grooves (38). The ring (58) prevents the anchored cable damaging the floor. <IMAGE>
