FIXTURE Original Filed Oct. 15, 1937 E R AXEL LNvENToE'.

Patented June 30, 1942 UNETED JTATES i ra'i iif ll OFFICE FIXTURE Einar Axel Dahm, Eshilstnna, Sweden 6 Claims.

This invention relates to fixtures and more specifically to fixtures which alsoact as supports.

In general, it is an object of the invention to provide a device of the character described, which will efficiently perform the purposes for which it is intended, which is simple and economical of construction, which can be expeditiousl conveniently and safely manipulated, and which can be readily manufactured and assembled.

Another object of the invention is to provide a device which is not easily removed from a wall unless the several parts are severally removed but which is so compact, due to the novel arrangement and interoositioning of the parts, that it occupies substantially no more space than, and appears to be no more complicated than, a simple push-button type; to provide such a device wherein the fixture, which is being fastened to a wall, itself, although of the simplest construction, assists the fastening means; and to provide a device, which may be used with a single-holed fixture, to give fastening strength and coaction usually found only in fixtures having many fastening holes.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description, taken in connection with the accompanying drawing, in which:

Fig. 1 is a cross-sectional view of a wall fixture according to the invention,

Fig. 2 is a cross-sectional view of a modified wall fixture according to the invention, and

Fig. 3 is an elevational View of a third embodiment of the invention similar to the one illustrated in Fig. 2. 1

Referring now to the drawing, and first to Fig. 1, 20 denotes a support member having at least a peripheral area thereof adapted to seat against a wall. In the embodiment of the invention illustrated in Fig. l, the support member 20 is completely flat and has all of one side thereof adapted to seat against a wall. The support member 29 is provided with an opening 22 therethrough. 24 is a cup-shaped positioning element resting with its rim against the outer surface of the support member 29. The positioning element 2 1 is provided with a first central aperture 25 in axial alignment with the opening 22 in member 26 and with two additional apertures 2% which have axes converging towards each other and meeting in or at the opening 22.

Two fastening members, in the form of pins 28, are carried in the apertures 25, respectively, said pins meeting and passing each other in the opening 22 and extending from there into the wall supporting the fixture. The opening 22 is of such a size that the pins 28, as positioned in the apertures 25, are held snugly together in the opening 22 by the periphery of the latter.

A securing screw i223 is threaded into and passes through the aperture 25, said screw extending to the opening 22 where its end bears against the pins 28 at or near their intersection. A look nut I29 is threaded onto the portion of the securing screw I23 projecting outwardly from the positioning element 24. A hook 339 is integral with the screw I28.

In the modification illustrated in Fig. 2, the support member 25a has, in addition to a flat peripheral portion 31 which seats against the wall 34, a portion 33 which is spaced from the wall. The positioning element 24a, which, in this instance, is shown as a flat disc, is positioned between the portion 38 of the support member 2%] and the wall 34, and the axes of apertures 26a converge away from the wall 34 toward the opening 22a in the portion 38. The securing screw [28a passes fully through the opening 22a, and has its inner end screwed into or otherwise secured in the central aperture 25a of the positioning element 24a. A hook 430 is attached to the screw [28a by means of a wing nut 229. A further disc-shaped nut 40 is positioned on the screw l28a between the positioning element 24a and the portion 38 of the support member 20a.

By tightening the wing nut 22 9, it is possible to exert on the pins 28a pressure which is directed outwardly at an angle to the axes of the obliquely disposed wall holes in which the pins 28 are held and to increase the frictional engagement between each pin and the inner surface of the corresponding wall hole to such an extent, that any danger of the fixture becoming loose is completely obviated.

The wall fixture shown in Fig. 3 is a combination of two fixtures of the type illustrated in Fig. 2 with a single hook 530 suspended from a bridge piece 52H attached to the two screws i28a by means of the wing nuts 2'29.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A wall fixture of the character described comprising a support member adapted to seat against a wall and provided with a single central opening, a positioning element assembled with said support member and having a first aperture disposed in axial alignment with said opening, said positioning element being provided with at least two additional apertures, the axes thereof converging towards each other and meeting at said opening, two fastening members carried in said additional apertures, respectively, and extending into the wall supporting said fixture, and a securing member extending between the single opening in said support member and said first aperture of said positioning element, said securing member having a portion in contact with portions of said fastening members to secure the latter in their positions.

2. A wall fixture of the character described comprising a support member having a first portion adapted to seat against a wall and a second portion spaced from the wall against which said first portion is seated, said second portion being provided with a single central opening, a positioning element disposed between said second portion of the support member and the wall, said positioning element having a first aperture in axial alignment with said opening and being provided with at least two additional apertures, the axes thereof converging towards each other and meeting at said opening, two fastening members carried in said additional apertures, respectively, and extending divergently into the wall supporting said fixture, and a securing member extending between said single opening in said second portion of the support member and said first aperture of said positioning element, said securing member having a portion ineontact with portions of said fastening members to secure the latter in their positions.

3. A wall fixture, as claimed in claim 2, in which said securing member includes a bolt passing through said opening in said second portion of the support member and having its inner end secured in said first aperture of the positioning element.

4. A wall fixture, as claimed in claim 2, in which said securing member includes a screw passing freely through said opening in said second portion of the support member and having its inner end secured in said first aperture of the positioning element, a nut being threaded on the portion of said screw projecting outwardly from said support member to bear against the outer surface of said second portion of the latter.

5. A wall fixture, as claimed in claim 2, including means to support an article on said fixture, said means being mounted on said securing member.

6. A wall fixture of the character described, comprising a wall plate having an opening and positioning means disposed over the opening and provided with at least three apertures, the axes thereof converging towards each other and meeting at said opening, two fastening members carried in said positioning means and extending through two of said apertures towards the opening in the plate at which point the fastening members cross each other and project into a wall supporting the fixture, and a securing member attached to said positioning means and extending through the third aperture, the inner end of said securing member resting against said fastening members at their crossing point.
