Abstract

Wall anchors and assemblies of the present disclosure include a plate, one more prongs, and a load bearing structure. The prongs are typically integral with a side edge of the plate and are typically curved in an upward towards the top edge of the plate.

First claim

We claim:

1. 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.

2. The wall anchor of claim 1 , wherein each base of the first and second prong is adjacent the top edge.

3. The wall anchor of claim 1 , and further comprising a hook, and wherein the bottom of the hook is disposed in a plane parallel to or above a top edge of the base of the prong.

4. The wall anchor of claim 1 , wherein the height is a least four times the thickness.

5. The wall anchor of claim 4 , wherein the height is at least five times the thickness.

6. The wall anchor of claim 1 , wherein the first prong curves upwardly in the direction of the top edge.

7. The wall anchor of claim 1 wherein each of the first and second prongs curves downwardly in a direction of the bottom edge.

8. The wall anchor of claim 1 wherein the wall-penetrating outer end of the first prong and the outer end of the second prong are coplanar.

9. The wall anchor of claim 8 , wherein each prong curves upwardly in the direction of the top edge of the base plate.

10. The wall anchor of claim 1 , and further including a shank disposed adjacent the bottom edge, and wherein the base of the shank is colinear with the base of the prong.

11. 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.

12. The wall anchor assembly of claim 11 , wherein the base plate includes opposing first and second major surfaces, and wherein the first major surface includes an adhesive construction disposed thereon.

13. The wall anchor assembly of claim 11 , wherein the base plate is pivotally coupled to the insertion plate at a first hinge segment.

14. The wall anchor assembly of claim 11 , wherein the base plate includes a guide aperture dimensioned for receipt of the prong.

15. The wall anchor assembly of claim 11 and further comprising a second insertion plate pivotally coupled to the base plate and including a proximal edge, a distal edge, and opposing side edges, the second insertion plate further including a second pair of curved prongs bent backward from the side edges of the second insertion plate, with a third prong having a base coincident and integral with a first of the side edges and a fourth prong having a base coincident and integral with the second of side edges, wherein each prong of the second pair extends outwardly along an arc to a wall-penetrating outer end and has a thickness measured between two flat side surfaces, and
wherein the base of each prong of the second pair has a height, and wherein the height is a least three times the prong thickness.

16. The wall anchor assembly of claim 15 , wherein the assembly is adjustable between an open state and a closed state, and wherein the first and second insertion plates include rear surfaces residing in planes substantially parallel to a front surface of the base plate in the closed state.

17. A kit for mounting an object, the kit comprising:
a wall anchor according to claim 1 ,
at least one of a) a compressible pillow, wherein the pillow has an initial thickness, and wherein the pillow thickness is greater than a length of each of the first and the second prongs, and
b) a removal strip, the removal strip including a tab and a wall-facing portion, the strip including insertion apertures for receipt of each of the first and second prongs.

18. The wall anchor of claim 17 , wherein the tab is foldable about a bending axis adjacent a top edge of the wall-facing portion and includes an aperture for receipt of a load bearing structure on the wall anchor.
