ABSTRACT:
An anchor assembly for retaining an elongated fastener member within an opening defined by a support wall having at least one concealed side. At least two elongated wire-like legs are positioned in parallel relation and a threaded apertured anchor member is slidably movable along the wire-like leg members and adapted to assume a first position parallel to the legs and to pivot toward a second position generally perpendicular to the legs when the anchor is advanced distally or when the leg members are withdrawn proximally to cause engagement therebetween. A connecting member in the form of a collar is positioned at the proximal ends of the legs and is configured and dimensioned for positioning within the opening of the support wall. The collar defines an aperture dimensioned and configured for reception of the elongated fastener member to facilitate attachment of the elongated fastener member to the anchor member through the threaded aperture when the anchor member is positioned at the distal side of the support wall and has assumed the second position generally perpendicular to the legs. The collar assures alignment of the fastener member with the aperture of the anchor member.
