Abstract

A device (H) to be mounted to a friable wall (W) comprises a body (10) and at least one main saber tooth (12) 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 transversely 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, at least one rigid saber tooth extending rearwardly and downwardly from an upper portion of said body and being rigidly connected thereto, said saber tooth being adapted to be driven into the substantially vertical support for securing said device thereto, and a secondary saber tooth extending rearwardly and downwardly from a lower portion of said body.

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 secondary saber tooth is adapted to be inserted into the support before said saber tooth of said upper portion is inserted therein.

4. A device as defined in claim 1, wherein said secondary saber tooth is arcuate, pointed at a rear free end thereof and rigidly connected to the body.

5. 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.

6. A device as defined in claim 5, wherein said enlarged load bearing surface of said saber tooth includes a substantially flat portion.

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

8. 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.

9. 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.

10. A device as defined in claim 9, 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.

11. 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.

12. A device as defined in claim 1, wherein a front part of said body is provided with a member adapted for engagement with an article such that the article can be mounted to the vertical support via said device.

13. A device as defined in claim 1, wherein said saber tooth is pointed at a rear free end thereof.

14. A device as defined in claim 1, wherein said device is made in one piece.

15. A device as defined in claim 1, wherein there are provided a single saber tooth on said upper portion of said body and a single secondary saber tooth on said lower portion of said body.
