Abstract
An expansion-type wall anchor having a generally hollow body, a nut element, at least one, and preferably two, retention elements and an actuating element. The retention elements are pivotally connected to the nut element and transition from an orientation substantially parallel to the body to an extended position substantially perpendicular to the body once positioned behind a wall in a rearward cavity. At the end of the body opposite the nut element, the body includes an anchor head which is of greater dimension than the remainder of the hollow body. The anchor head is positioned generally transverse to the longitudinal axis of the body and secures the body to the exterior surface of the wall. The actuating element is positioned in an opening in the anchor head and extends within the length of the body to engage the nut element. Flanges extending from the anchor head preclude rotation of the anchor once it is embedded in the exterior surface of the wall. In some preferred embodiments, rotation of the actuating element creates a force which is exerted on deformable legs to cause the retention elements to transition from an orientation substantially parallel to the body to an extended position substantially perpendicular to the body. Continued rotation of the actuating element draws the retention elements into contact with the interior surface of the wall. Once the body is in place, the actuating element can be removed and the anchor body will remain in place.
