Abstract: A wall anchor for insertion in wall board and having a cylindrical body with an outer thread and an axial through passage extending from a flanged proximal end to a saw-tipped distal end. The cylindrical body comprises a proximal extension and a distal extension of approximately the same length equal to the width of wall board. The flange at the proximal end may be provided with locking tabs and the saw-tipped end may be provided with mashing teeth on a circumference of revolution smaller than that of the sawing teeth.

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 when the legs are in a first orientation and a second position generally perpendicular to the legs when the position of the legs is rotated to a second position. A connecting member in the form of a collar is attached to the proximal ends of the legs and is configured and dimensioned for positioning within the opening of the support member.

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a second position generally perpendicular to the legs when the anchor is advanced distally or when the leg members are withdrawn proximally to cause engagement therebetween.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.

Abstract: A fastening device of the type having a stem, toggle arms at the opposite end of the stem, extending outwardly from an extended axis of the stem, a toggle hinge forming a part of the toggle arms and connecting the toggle arms to the stem and elastically biasing the toggle arms in the extended position. The toggle arms are pivotable about the toggle hinge to a closed position extending substantially parallel with the extended axis of the stem. A strap extends across the extended axis of the stem between the extremities of the toggle arms to maintain the toggle arms in the extended position. The extremities of the strap and the toggle arms are connected and a mid-hinge is formed centrally of the strap at the extended axis of the stem so that the portions of the strap on either side of the mid-hinge may pivot about the hinge to move the toggle arms and strap portions to the closed position.
