2 Claims. (Cl. 248-28) The improved suspension device comprising the present invention is primarily adapted for use in suspending pictures, mirrors and the like on a wall. The invention is, however, capable of other uses and, if desired, the same may, with or without modification be employed for suspending other objects or bodies that are to be supported from a wall surface.

The present method of hanging pictures and like objects from a wall consists in attaching a wire or string at its ends to spaced points at the opposite sides of the picture frame and passing the wire or stringover a hook attached to the wall. This method possesses numerous limitations, principal among which is that a picture thus hung will frequently slip to a non-horizontal position due to vibrations, jars in cleaning and other causes. Furthermore, the installation of pictures on the wall by this method is accomplished by numerous difficulties. Since it is considered desirable that the hanging means be concealed, it is necessary that the wire or string attached to the picture be made relatively short so that when passed over the supporting means on the wall the upper edge of the picture will be high enough to conceal the suspension means. Where the wire is sufiiciently short as to accomplish this purpose, it is maintained so close to the back of the picture that it is difiicult to reach behind the picture and apply the wire to the supporting hook.

Additionally, particularly where heavy pictures are concerned, a short Wire applies a tremendous strain at its ends to the nails or other fastening devices by means of which it is attached to the picture frame, thus resulting in splitting of the wood of which the frame is made and sometimes resulting in dropping of the picture. One decided disadvantage that is attendant upon this method of hanging pictures is the diificulty of estimating the length of wire which is required to maintain the picture at a predetermined elevation. Due to the fact that pictures are invariably hung at close range, difliculty is always experienced in adjusting the picture to a true horizontal level and it is necessary to survey the picture at a distance and make one or more readjustments before the desired horizontal efiect is achieved. Such a ditficulty is of course particularly annoying if the picture is hung at a great height where it is necessary to stand upon a stepladder or other support in order to hang the picture.

Yet another difficulty accompanying this method of hanging pictures arises from the fact that certain inferior makes of picture wire have a tendency to stretch as time elapses, thus lowering the elevation of the pictures to a noticeable extent and frequently causing the suspension means to appear, with a consequence that the picture must be taken down and the suspension wire readjusted.

Another method that is sometimes employed in hanging picture and mirror frames consists in the provision of one or more metal loop devices which are attached to the frames at strategic points and which, when so attached, are designed for registry with the head of a nail or other supporting means on the wall. These devices occupy positions of such close proximity to the plane of the picture frame that it is quite ditficult to align them with their counterpart elements on the Wall. Where the frame-attached device or devices consist of metal loops hinged to the picture frame, as they frequently do, it is very difiicult to maintain them in an outstanding position where they may be hooked over the wall suspension means. Frequently such metal loops will tilt to a pendulous position and, when this occurs, it is necessary to again orient them for a succeeding attempt to hang the picture.

The present invention is designed to overcome the above noted limitations that are attendant upon such picture hanging methods and apparatus, and toward this end it contemplates the provision of a pair of cooperating supporting devices, one designed for attachment to the wall and the other designed for attachment to the picture frame and which, when thus attached and assembled in operative relationship, will automatically fix the frame in a horizontal position at the desired level against ordinary conditions of displacement.

The provision of a suspension device which will accomplish the above mentioned aim being the principal object of the invention, a further object is to provide a suspension device which will permit removal of the picture frame for cleaning or other purposes and rehanging thereof at a definite fixed level by unskilled hands. By such an arrangement the improved picture hanging device of the present invention will be further valuable in such places as a hotel, where pictures are frequently changed from room to room to satisfy the varying esthetic tastes of the guests, or for purposes of replacement. Additionally, in art galleries where pictures frequently undergo a change of location, the present picture suspension device will be found useful.

It is another object of the invention to provide a mirror or picture frame suspension device of this character in which the picture attachment device and the wall attachment device may each be formed of a light sheet metal stamping with the minimum of deformation thus materially contributing to the low cost of manufacture. A similar and related object is to provide such a suspension device in which both parts thereof are of one-piece construction.

Another object of the invention is to provide a suspension device of this sort in which the element secured to the picture frame may be secured in proper position by a single screw, yet which when secured in position will not tilt about the securing axis.

Still another object of the invention is to provide a twopiece suspension device in which the cooperating parts thereof are interchangeable when a number of the wallattached parts are installed at diiferent locations and a number of the picture-frame-attached parts are installed on different picture frames, thus enabling interchanging and substitution of pictures at various predetermined locations.

It is also an object of the invention to provide a suspension device for picture frames and the like including a wall attachment of novel construction which is so fashioned that the securing device employed in connection therewith will be driven into the supporting wall at a downward inclination so as to materially increase the weight carrying capacity of the device.

The provision of a suspension device for picture frames which is extremely simple in its construction; onewhich is possessed of no moving parts and which, consequently, is unlikely to get out of order; one which is rugged and durable and which, therefore, is possessed of long life; and one which otherwise is well adapted. to perform the service required of it, are further desiderata that have ment 1.0 as a whole.

3 been borne in mind in the production and development of the present invention.

In the accompanying single sheet of drawings forming a part of this specification, one embodiment of the invention has been shown for illustrative purposes.

In these drawings:

Fig. l is a perspective view of the cooperating members which constitute the improved picture frame suspension means comprising the present invention;

Fig. 2 is a side elevational view of the wall-attached element of the suspension device;

Fig. 3 is a vertical sectional view taken substantially centrally through the wall-attached element of Fig. 2 and showing the latter applied to a wall surface; and

Fig. 4 is a vertical sectional view taken substantially centrally through the picture-frame-attached element showing the same secured to the rear side of a picture frame.

in compliance with Section 4888 of the Revised Statutes, a preferred form of the invention has been shown in the drawings and will be described herein, but it should be understood that the invention is not limited to the specific disclosure made, and that the appended claims should be construed as broadly as the prior art will permit.

Referring now to the drawings in detail and in particular to Fig. 1, the improved suspension device comprising the present invention is in the form of a two-piece separable assembly including a wall attachment 1i and a frame attachment 12, the former being adapted to be applied to a vertical wall surface and the latter being adapted to be applied to the rear face of a picture frame or similar object to be supported on the wall. The attachment is designed to be permanently attached to the wall and the attachment l2 permanently applied to the frame, and the two attachments are capable of ready assembly and disassembly for picture hanging or removal purposes.

In the following description of the wall attachment 10 and of the frame attachment 12, reference to forward and rearware directions will be made with respect to the wall surface from which the picture or other object is to be supported. Thus, any reference to a forwardly extending portion or part of the wall attachment will imply a direction extending outwardly from the wall into the room enclosure. Such a reference applied to the frame attachment 12 will imply a direction extending toward the back of the frame and away from the wall structure. Similarly, a rearward direction applied to the frame attachment 1?. will imply a direction extending toward the wall surface.

The wall attachment 10 is in the form of a one-piece light sheet metal stamping including a substantially flat back or plate portion 14 designed for face-to-face contact with the wall surface and having its lower end turned forwardly as at 16 and upwardly as at 18 to provide a cradle or ledge portion.

A narrow strip 29 in the medial regions of the sheet metal attachment is struck forwardly from the plane of the metal and is curled upwardly as at 22 and inwardly as at 24 to provide a tubular attachment portion adjacent the top of the member. A pair of diametrically-opposed holes or

openings

26 and 28 are formed in the curled member 24) and are so disposed relative to each other that a nail 30 or other anchoring may be driven through these holes-and into a wall, such as the plaster wall designated at 31 in Fig. 3, at a rearwardly and downwardly inclined angle to enhance the weight-carrying ability of the attach- The outwardly-struck strip 21 creates a void 32 in the medial regions of the attachment which extends from a region adjacentthe top of the attachment downwardly and through the central portion of the outwardly and upwardly turned lower end thereof, the void thus created at the lower end being designated at 34. The void 32 provides a pair of

parallel side portions

36 and 38 as well as generally horizontal extending ledge portions 46 and 42 on each side of the void 34.

The attachment 12 is in the form of a sheet metal plate having a forward attachment portion 50, a down wardly-projecting offset flange portion 52 and an intermediate inclined portion 54. The flange portion 52 is provided with a pair of spaced notches 56 and 58 which extend upwardly from the lower edge thereof and provide therebetween a central downwardly-extending tongue 6!

Marginal tongues

62 and 64 are formed as a consequence of the slots 56 and 58, respectively. The forward plate portion 5t) is provided with a central aperture 66 therein designed for reception therethrough of a fastening device such as a screw 68, the head '70 of which firmly abuts the plate portion 58, as shown in Fig. 4. A pair of pointed tongues 72 may be struck forwardly from the metal of the plate 50 and are adapted to penetrate the wood or other material of a picture frame such as the frame 74 on opposite sides of the screw 68 to prevent tilting of the attachment 12 relative to the frame after the same has been applied thereto.

in suspending the picture frame 74 from the wall 31, the attachment 10 is applied to the wall at the desired location in the manner shown in Fig. 3. The attach ment 1?. is applied to the rear face of the picture frame 74 on the vertical center line and along the upper horizontal cross piece of the frame below the upper edge thereof, as shown in Fig. 4. It is then merely necessary to insert the tongue 69 into the void 34 so that the upper horizontal edges of the slots 56am 58 rest upon the

ledge portions

40 and 42, respectively, with the marginal tongues and 64 straddling the outer side edges of these ledge portions. The forward extent of the void sufficiently restricted that there will be little, if any, fore and aft play between the two attachments 10 and i2, and the width of the tongue 60 is but slightly less than the width of the void 34 so that there shall be little,

if any, side play. Obviously, the

ledge portions

40 and 42 assume the same general horizontal level as do the upper edges of the slots 56 and 53. Thus, when the picture is applied to the wall in the manner outlined above, the same will be constrained to assume a horizontal position of stable equilibrium.

The invention is not to be limited to the exact arrangement of parts shown in the accompanying drawings and described in this specification, as various changes in the details of construction may be resorted to without departing from the spirit of the invention. For example, either the central tongue 69 or the

flanking tongues

62 and 64 could be omitted without harm. Only insofar as the invention has particularly been pointed out in the accompanying claims is the same to be limited.
