Wall anchor
First Claim
1. A fastening anchor assembly adapted for fastening an object to a first side surface of a wall or other support member having an open area on a second side surface of the wall opposite said first side surface, the wall having a hole therethrough opening at each of said surfaces and of a first specified diameter for receipt therethrough of at least a portion of said anchor assembly, said assembly comprising in combination a generally U-shaped mounting strap having a central bight portion and generally parallel first and second legs extending longitudinally from said bight portion and each terminating in a foot portion extending longitudinally generally perpendicularly from the associated leg portion in a direction away from the legs and adapted for engaging said wall first side surface, elongated anchoring blade means operably pivotally coupled to said legs for swinging motion-between a wall-hole-installation collapsed position nested against the legs adapted to enable insertion of the legs and blade means through the wall hole and a swing-out wall-mounting expanded position adapted for said blade means to clamp engage said wall second side surface with said leg feet clamp engaging said wall first side surface, and an operating threaded member operably disposed between said legs and operably threadably drivingly engaged with said blade means, said operating member having a distal end disposed for reactive force abutment with said strap bight and a head end configured for imparting rotational torque to said member such that rotation in a first direction while said distal end abuts said strap bight, after said strap legs and bight have been inserted into the wall hole to position said blade means in the open area adjacent the wall second surface, draws said blade means toward said strap feet for clamping the wall therebetween to thereby mount the anchoring assembly on the wall.

Abstract
A fastening anchor assembly and manual method for fastening an object to a hollow wall. In most embodiments a generally U-shaped mounting strap of the assembly has a central bight and parallel first and second legs extending longitudinally from the bight through a first mounting hole in the wall. A strap foot portion or separate mounting flange extends perpendicularly to the legs for engaging the wall exterior side surface. One or two anchoring blades are operably pivotally coupled to the strap for swinging motion in a single plane defined by the longitudinal axes of the blades and strap and between a collapsed position nested adjacent the strap and a swung-out expanded position wherein the blade(s) clamp-engage the wall interior surface while the leg feet or flange clamp-engages the wall exterior surface. The position and orientation of the now wall-hidden blade remains visibly indicated to the installer by the orientation of the strap exposed to view of the installer. Preferably an operating screw-bolt is disposed between the strap legs and threadably drivingly engages the blade(s) such that screw rotation forces the blade(s) toward the wall interior surface for positioning the blade for mounting the anchoring assembly on the wall. The object is fastened to the wall with a separate load-carrying fastener member(s) that extends through a second mounting hole(s) in the wall and threadably engage the blade(s) so that the operating screw bolt is isolated from object-imposed forces and heavy loads can be reliably carried on the hollow wall via the overall anchoring assembly structure.

13. The anchor assembly of 12 wherein said second strap leg foot has a hardware mounting fastener fixed thereon on the surface thereof adapted to face said first side surface of said wall in the mounted condition of said anchor assembly, said hardware mounting fastener having a threaded shaft protruding from the said second foot in a direction away from the U-strap protrusion direction and being adapted for coupling to mounting hardware for fastening the object said anchor assembly when mounted to the wall.
- 20. A fastening anchor assembly adapted for fastening an object to a first side surface of a wall or other support member having an open area on a second side surface of the wall opposite said first side surface, the wall having a hole therethrough opening at each of said surfaces and of a first specified diameter for receipt therethrough of at least a portion of said anchor assembly, said assembly comprising in combination a generally U-shaped mounting strap having a central bight portion and generally parallel first and second legs extending longitudinally from said bight portion and each terminating at a free end portion, a mounting flange member extending longitudinally generally perpendicularly to the associated strap leg in a direction away from the legs and adapted for engaging said wall first side surface, an elongated anchoring blade operably pivotally coupled to said legs via apertures in said blade individually slidably receiving said legs therethrough for enabling swinging motion between a wall-hole-installation collapsed position nested against the legs adapted to enable insertion of the legs and blade through the wall hole and a swing-out wall-mounting position adapted for said blade to clamp engage said wall second side surface with said leg feet disposed adjacent said wall first side surface, said mounting flange member having a mounting hole adapted to receive the leading end of a through-wall mounting fastener therethrough for passage through the wall, said blade having a mounting nut means for fastening engagement with the leading end of the fastener member after passage through the wall, said flange member mounting hole and said blade mounting nut means being maintained oriented in coaxial alignment in the wall clamping condition of said blade and said mounting flange member by an operable coupling action orientation of said strap legs relative to said blade apertures and mounting flange member.
