Abstract

A device (H) to be mount to a friable wall (W) comprises a body (10) and at least one main saber tooth (21) extending rearwardly from an upper portion of the body (10) and adapted to be driven into the wall (W) for securing the device (H) thereto. The main saber tooth (12) is arcuate and has a pointed rear free end (22), and is adapted to be arcuately driven into the wall (W). An arcuate and pointy secondary saber tooth (14) extends rearwardly from a lower portion of the body (10) for insertion into the wall (W) before the main saber tooth (12) is inserted therein. The main saber tooth (12) defines a lower enlarged, and typically flat, load-bearing surface (30) for bearing against material of the wall (W). The main saber tooth (12) includes an upper transversally curved surface (32). A hook member (20) is provided on a front part of the body (10) for suspending items therefrom once the device (H) has been mounted to the wall (W).

Claims

1. A device for mounting to a substantially vertical support, typically to friable walls, comprising a body adapted to be located on a visible side of a substantially vertical support in which said device is to be mounted, and at least one saber tooth extending rearwardly from said body and adapted to be driven into the substantially vertical support for securing said device thereto.

2. A device as defined in claim 1, wherein said saber tooth is arcuate and is adapted to be arcuately driven into the substantially vertical support.

3. A device as defined in claim 1, wherein said saber tooth extends rearwardly and downwardly from an upper portion of said body and is pointed at a rear free end thereof.

4. A device as defined in claim 1, wherein a secondary saber tooth extends rearwardly from a lower portion of said body for insertion into the support before said saber tooth of said upper portion is inserted therein.

5. A device as defined in claim 4, wherein said secondary saber tooth is arcuate and is pointed at a rear free end thereof.

6. A device as defined in claim 1, wherein said saber tooth includes a lower enlarged load bearing surface for bearing against material of the support.

7. A device as defined in claim 6, wherein said enlarged load bearing surface of said saber tooth includes a substantially flat portion.

8. A device as defined in claim 1 wherein said saber tooth includes an upper transversally curved surface.

9. A device as defined in claim 1, wherein a hook member is provided on a front part of said body for suspending items therefrom once said device has been mounted to the vertical support.

10. A device as defined in claim 1, wherein said body comprises a horizontally elongated and vertically oriented plate defining saw teeth along a lower edge thereof with elbowed wings being provided at longitudinal ends thereof, one said saber tooth being provided at each of said elbowed wings and extending rearwardly therefrom for insertion into the support.

11. A device as defined in claim 10, wherein said body further comprises a V-shaped member extending downwardly from one of said horizontal plate and said elbowed wings, a secondary saber tooth extending rearwardly from a lower section of said V-shaped member.

12. A device as defined in claim 1, wherein said body defines a front striking surface located substantially opposite said saber tooth and adapted to be forcibly acted on for inserting said saber tooth in the support.

28. A method as defined in claim 1, wherein the support is a wooden structural component.

13. A method for suspending an item to a substantially vertical support, typically to friable walls, comprising the steps of:

(a) providing a wall mountable device having a body and at least one main saber tooth extending rearwardly from said body;

(b) positioning said main saber tooth against the support; and

(c) exerting force on said body for inserting said main saber tooth into the support and thereby securing said device thereto.

14. A method as defined in claim 13, wherein said main saber tooth is arcuate and is arcuately driven in step (c) into the support.

15. A method as defined in claim 13 wherein said main saber tooth extends rearwardly and downwardly from an upper portion of said body and is pointed at a rear free end thereof.

16. A method as defined in claim 13, wherein a secondary saber tooth extends rearwardly from a lower portion of said body for insertion before step (c) into the support and prior to inserting said main saber tooth in the support.

17. A method as defined in claim 16, wherein said secondary saber tooth is arcuate and is pointed at a rear free end thereof.

18. A method as defined in claim 13, wherein said main saber tooth includes a lower enlarged load bearing surface for bearing against material of the support.

19. A method as defined in claim 18, wherein said enlarged load bearing surface of said main saber tooth includes a substantially flat portion.

20. A method as defined in claim 13, wherein said main saber tooth includes an upper transversally curved surface.

21. A method as defined in claim 13, wherein a hook member is provided on a front part of said body for suspending items therefrom once said device has been mounted to the vertical support.

22. A method as defined in claim 13, wherein said body comprises a horizontally elongated and vertically oriented plate defining saw teeth along a lower edge thereof with elbowed wings being provided at longitudinal ends thereof, one said main saber tooth being provided at each of said elbowed wings and extending rearwardly therefrom for insertion into the support.

23. A method as defined in claim 22, wherein said body further comprises a V-shaped member extending downwardly from one of said horizontal plate and said elbowed wings, a secondary saber tooth extending rearwardly from a lower section of said V-shaped member.

24. A method as defined in claim 13, wherein said body defines a front striking surface located substantially opposite said main saber tooth and adapted to be forcibly acted on in step (c) for inserting said main saber tooth in the support.

25. A method as defined in claim 13, wherein the support is a wall.

26. A method as defined in claim 25, wherein the wall is a friable wall.

27. A method as defined in claim 26, wherein the friable wall is a gypsum wall.
