Wall anchor

USPTO Application #: 20060182517
Title: Wall anchor
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). (end of abstract)

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to wall fixtures and, more particularly, to a wall anchor for use in different materials including friable materials, e.g. gypsum.

[0003] 2. Description of the Prior Art

[0004] There are various wall anchors available on the market, including plastic inserts which are hammered in a hole previously defined in a wall, wherein a fastener, such as a screw, is then engaged in the plastic insert, causing it to expand such that the assembly of the insert and the fastener is set firmly in the wall.

[0005] Toggle bolts also exist, wherein rotation of a bolt causes wings to deploy behind the wall and to ultimately abut the inside of the wall thereby firmly anchoring the bolt to the wall.

[0006] Both these types of anchors necessitate that a hole be previously drilled in the wall. On the other hand, there exists wall anchors defining a pointed cutting end and large threads, which are adapted to, in a single step, be rotatively driven in the wall thereby drilling their own hole in the wall with the large threads of the anchor compacting the gypsum and becoming firmly set therein. These types of anchors must be installed by way of a screwdriver and typically by a power driven screwdriver bit.

SUMMARY OF THE INVENTION

[0007] It is therefore an aim of the present invention to provide a novel wall anchor of simple construction and simple installation.

[0008] Therefore, in accordance with the present invention, there is provided 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

[0009] More particularly, said saber tooth is arcuate and is adapted to be arcuately driven into the substantially vertical support.

[0010] Specifically, said saber tooth extends rearwardly and downwardly from an upper portion of said body and is pointed at a rear free end thereof.

[0011] Typically, said saber tooth includes a lower enlarged load bearing surface for bearing against material of the support, and more particularly said enlarged load bearing surface of said saber tooth includes a substantially flat portion.

[0012] Said saber tooth may define an upper transversally curved surface.

[0013] Furthermore, 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.

[0014] Typically, said secondary saber tooth is arcuate and is pointed at a rear free end thereof.

[0015] For example, 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.

[0016] Generally, 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.

[0017] Also in accordance with the present invention, there is provided 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.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Having thus generally described the nature of the invention, reference will now be made to the accompanying drawings, showing by way of illustration a preferred embodiment thereof, and in which:

[0019] FIG. 1 is a rear perspective view of a wall mounted hook in accordance with the present invention;

[0020] FIG. 2 is a front perspective view of the wall mounted hoot of FIG. 1;

[0021] FIG. 3 is a left side elevational view of the wall mounted hook of FIG. 1;
