WALL-BOARD FASTENER Filed Feb. 19, 1951 Y INVENTORS Thoma.) B. Neclrar Florence Kennedy ATTORNEY United States Patent Ofiice WALLBOARD FASTENER Florence Kennedy and Thomas B. Neckar, Houston, Tex.

Application February 19, 1951, Serial No. 211,702

3 Claims. (Cl. 248-301) This invention relates to a wall anchor.

An object of the invention is to provide an anchor of the character described that can be easily and securely attached to a wall, or ceiling, and forming a connection for fastening articles, such as pictures, and the like, to the wall.

The invention has been particularly designed to be securely anchored to artificial walls which are composed of frangible material such as artificial wall boards.

Walls of the type above referred to are of such composition that they will not hold nails, or screws, which penetrate the same, but will disintegrate upon a nail or screw being driven therein so that the nail, and the like, can be easily pulled out. It is the prime object of the present invention to provide an anchor that may be attached to an artificial wall without crushing the surrounding material and which, when attached, will give sufiicient strength to form the required attachment for other objects.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, arrangement 'of parts, and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1 is a front elevation of an anchor having 1aikhook thereon for supporting a wall picture, or the Figure 2 is a vertical, sectional view taken on the line 22 of Figure 1;

Figure 3 is a cross-sectional view taken on the line 3--3 of Figure 1;

Figure 4 is a rear elevation; and

Figure 5 is a reduced, transverse, sectional view, as applied to a wall board.

This application is a continuation in part of a previous application of the same applicants, Serial No. 123,248, filed October 24, 1949, which became abandoned.

Referring now more particularly to the drawings, wherein like numerals of reference designate the same parts in each of the figures, the numeral 1 designates a disc, preferably formed of thin sheet metal or other similar material; and whose margin 2 is, preferably, rearwardly turned to form a close, seal-like fit with the wall, and which margin may or may not be formed with a sharp rearwardly directed edge.

The particular shape of the disc 1 is not essential, as thin, rigid material of any selected shape may be used instead thereof.

In the present illustration, the disc is formed with the hanging hook 3 to which a picture frame or the like may be connected. Other types of attaching means may be employed in lieu of the hook.

The disc may be attached to the wall by means of a staple 6, as shown in Figure 5.

As is illustrated in the present drawing, the disc 1 is provided with

bearings

5, 5 therethrough, which converge from the forward face thereof and extend forwardly beyond the front face of the disc, and between these bearings, and forming part of them, there are the

guides

4, 4, which diverge from the front face of the disc. The

guides

4, 4, preferably extend rearwardly be- Patented Nov. 2, 1954 yond the rear face of the disc and somewhat beyond the margin 2, and may be formed with sharp extremities capable of penetrating a wall upon which the anchor is secured.

When the staple 6 is inserted its points will rest against said guides at the front and the staple is then driven home. As driven home the legs of the staple will bear against the margins of the openings opposite said guides and will be spread and curved outwardly and will penetrate the wall, as shown in Figure 5. The jar of the stroke which drives the staple will be taken up by the guides 4 and will cause very little injury to the wall board itself, and after the points of the staple have passed beyond said guides the guides will still direct the points in a forward, outwardly curved course to minimize the injury to, and crushing of, the material of the board.

When driven home, the legs of the staple will have spread and can not easily be detached from the wall and will securely maintain the anchor in place. The

guides

4, 4, and the margin 2 will also engage the wall .and further maintain the anchor securely in position thereon.

The drawings and description are illustrative merely, while the broad principle of the invention will be defined by the appended claims.

What we claim is:

1. A wall anchor comprising, a plate-like body formed of relatively thin material and having openings which diverge from the front of the body and are spaced apart, guides forming the rear sides of the openings and which diverge rearwardly to receive and spread the points of the legs of a staple inserted through the openings, the forward margins of the openings, opposite the guides, forming fulcrums against which the legs of the staple bear as the staple is driven home.

2. A wall anchor comprising, a plate-like body formed of relatively thin, approximately rigid, material, and

aving a rearwardly turned marginal portion terminating in a sharp rearwardly directed edge, said body having spaced openings which diverge from the forward to the rearward side of the body, the material on the rearward sides of the openings diverging rearwardly and forming guides to engage the points and spread the legs of a staple inserted through the openings said guides terminat ing in sharp rearwardly directed edge portions extending rearwardly beyond said marginal portion.

3. A wall anchor comprising, a plate-like body formed of relatively thin, approximately rigid, material, and having a rearwardly turned marginal portion which terminates in a sharp rearwardly directed edge, said body having spaced openings which diverge from the forward to the rearward side of the body, the material on the rearward sides of the openings diverging rearwardly .and forming guides to engage the points and spread the legs of a staple inserted through the openings, said guides extending rearwardly beyond the marginal portion.
