Claims18
A wall anchor comprising:
- a base plate including opposing front and back surfaces, a top edge, a bottom edge and two opposing side edges;
- and
- a pair of curved prongs bent backward from the side edges of the base plate, with a first prong having a base coincident and integral with a first of the side edges and a second prong having a base coincident and integral with the second of side edges, wherein each prong extends outwardly along an arc to a wall-penetrating outer end and has a thickness measured between two flat side surfaces,
- wherein the wall-penetrating outer end of each prong is tapered to a triangular cross-sectional shape,
- wherein the base of each prong has a height, and wherein the height is a least three times the prong thickness,
- and wherein the base of each prong is substantially coplanar with the front surface of the base plate.

A wall anchor assembly comprising:
- a base plate;
- a first insertion plate pivotally coupled to the base plate and including a proximal edge, a distal edge, and opposing side edges, the insertion plate further including:
- a pair of curved prongs bent backward from the side edges of the base plate, with a first prong having a base coincident and integral with a first of the side edges and a second prong having a base coincident and integral with the second of side edges, wherein each prong extends outwardly along an arc to a wall-penetrating outer end and has a thickness measured between two flat side surfaces,
- wherein the wall-penetrating outer end of each prong is tapered to a triangular cross-sectional shape,
- wherein the base of each prong has a height,
- wherein the height is a least three times the prong thickness, and
- wherein the base of each prong is substantially coplanar with a front surface of the base plate.
