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.
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.
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.
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.
It is therefore an aim of the present invention to provide a novel wall anchor of simple construction and simple installation.
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.
More particularly, said saber tooth is arcuate and is adapted to be arcuately driven into the substantially vertical support.
Specifically, said saber tooth extends rearwardly and downwardly from an upper portion of said body and is pointed at a rear free end thereof.
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.
Said saber tooth may define an upper transversally curved surface.
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.
Typically, said, secondary saber tooth is arcuate and is pointed at a rear free end thereof.
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.
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.
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.
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:
The body 10 includes a visible, typically decorative, front surface 16 and a plane rear surface 18. The rear surface 18 is adapted to extend against a visible side V of the wall W once the hook H has been mounted thereto. The front surface 16 is provided, for instance, with a hook member 20 from which an article, e.g. a picture frame, clothes, etc., can be suspended.
The upper and lower saber teeth 12 and 14 are each curved downwardly and terminate rearwardly with respective pointed tips 22 and 24.
The hook H is easily installed as fallows. With reference to
Once the lower saber tooth 14 is in the wall W and with a lower end 26 of the body 10 abutting the wall W, an upper portion of the body 10, such as a striking surface generally located at a location indicated by reference numeral 28, is pressed by hand or possibly impacted with a hammer M, as illustrated in
A bottom surface 30 of the upper saber tooth 12 is enlarged and flat such as to provide a wide load bearing surface between the upper saber tooth 12 and the wall material (e.g. gypsum), thereby providing resistance to the hook H ripping downwards through the wall material, when a load is suspended from the hook member 20 thereof. A top surface 32 of the upper saber tooth 12 is rounded to facilitate the insertion of the upper saber tooth 12 in the wall material.
The hook H can, for instance, be made of zinc so that it can be die-casted.
In a variant (not shown) of the hook H, a conventional leveler (i.e. a horizontally elongated and vertically oriented plate defining saw teeth along its lower edge and having elbowed wings at the longitudinal ends thereof that can be nailed to an article, e.g. picture, such that the picture can be mounted to the wall by suspending the leveler attached thereto from a fastener, e.g. a nail, previously secured to the wall) is provided at each of its elbowed wings with a rearwardly extending upper saber tooth. A V-shaped member that extends downwardly from the horizontal plate or from the elbowed wings has a lower saber tooth extending rearwardly therefrom. This variant can thus be secured to an article, i.e. a rear surface of a picture, by first pressingly engaging the lower saber tooth in the article, followed by pressingly engaging the upper saber teeth therein. In such a case, the upper and lower saber teeth replace the conventional nails that are inserted through holes defined in the leveler's wings and into the rear of the picture to be hung from the wall.
