ABSTRACT:
An anchor assembly for use on a wall to support a fixture or load thereon which includes an elongated anchor plate sized to be received in a hole formed in a wall and which in the operative position abutts the blind side of the wall. A pair of flexible leg members are hingedly connected to the anchor plate in a manner to control the positioning of the anchor plate on the blind side of the wall, and having a slip collar slidably mounted on the leg members whereby the collar is ratcheted along the leg member in a unidirectional manner to firmly secure the anchor plate to the blind side of the wall and whereby the collar can be readily released to render it freely slidable along the leg members to facilitate assembly and removal of the anchor assembly.
In one embodiment the respective leg members are hingedly connected to the anchor plate by a hinge strap connected to the anchor plate, and the respective leg members having an integrally formed hinge pin which is retained in the hinge strap whereby the anchor plate can be pivoted between a normal position or parallel position relative to the respective leg members.
