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, 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, said saber tooth including an upper transversally curved surface and a lower enlarged load bearing surface for bearing, when the saber tooth is lodged within the support, against material of the support, the load bearing surface having a portion that is transversally substantially flat.

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 a secondary saber tooth is provided below said saber tooth.

4. A device as defined in claim 3, wherein said secondary saber tooth is smaller than said saber tooth.

5. A device as defined in claim 4, wherein said secondary saber tooth is arcuate, is pointed at a rear free end thereof and extends rearwardly and downwardly from a lower portion of said body.

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

7. 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.

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

9. 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 arcuate upper saber tooth extending rearwardly and downwardly relatively to a front surface of said body, the device further comprising at least one arcuate lower saber tooth smaller than said upper saber tooth and extending rearwardly and downwardly from said body and below said upper saber tooth, both the upper and lower saber teeth being concave on an underside thereof when the device is mounted.

10. A device as defined in claim 9, wherein said upper and lower saber teeth are each pointed at respective rear ends thereof.

11. A device as defined in claim 9, 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.

12. A device as defined in claim 9, wherein said body defines a front striking surface located substantially opposite said upper saber tooth and adapted to be forcibly acted on for inserting said upper saber tooth in the support.
