Description

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to an apparatus and method for hanging a picture or other wall hanging or object on a wall surface to cause the wall hanging, once leveled or set to a desired orientation, to return to the desired orientation if it is accidentally disturbed.

Certain apparatus for maintaining a wall hanging in a straight or level condition are known in the art, for example U.S. Pat. No. 2,657,887, but such apparatus generally tends to be relatively complex in construction, difficult to use, expensive in cost, and not always as effective as desired.

It is therefore an object of this invention to provide an apparatus and a method of hanging a wall hanging that will cause the wall hanging to return to its desired original orientation if it is accidentally disturbed.

In certain cases a more pleasing appearance of the wall hanging may be obtained by tilting it slightly downward as by moving the top of the wall hanging outward from the wall surface. Accordingly, it is a further objective of this invention to provide an apparatus and a method which allows a wall hanging to assume a desired angle or downward tilt with respect to the wall surface on which it hangs.

It is still another object of this invention to provide an apparatus and a method for hanging a wall hanging on a surface at a desired downward tilt with respect to the wall such that the wall hanging will effectively return to its initial desired orientation if it is disturbed.

Other objects of the invention are to provide apparatus for hanging a wall hanging which is relatively easy and convenient to install on a wall surface and to use in conjunction with the wall hanging, and which is relatively inexpensive in cost.

The present invention may be fully understood from the following claims, description of the preferred embodiment and brief description of the drawing.

Summarizing the apparatus of the present invention, it will be seen to comprise a pair of knob members, means for mounting the knob members at the wall surface generally in an outward protruding and spaced apart relation, a suspension means for suspending the wall hanging from its lower marginal border area and comprising a cable means for encircling the pair of knob members in at least one complete loop, and connecting means for connecting the wall hanging at its upper marginal border area to the cable means intermediate the pair of knob members or in other words, operatively to the wall surface. The method of the present invention may generally comprise the steps of mounting a pair of knob members at the wall surface in a spaced apart relation slightly less than the width of the wall hanging, looping the middle portion of a suspension cable around the pair of knob members in at least one complete loop, extending one end portion of the suspension cable generally downward from each knob member, attaching each end portion of the suspension cable to the lower marginal border area of the wall hanging at laterally opposite positions, and connecting the wall hanging from its upper marginal border area to the middle portion of the suspension cable between the knob members or in other words, operatively to the wall surface.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to FIGS. 1, 2 and 3 of the drawing there is shown apparatus for attaching a wall hanging, represented by a frame 10, to a wall surface 11 (FIG. 3). The wall hanging may take the form of a conventional picture having the frame 10, or may take any other form. The frame 10 is one example of a marginal border area of the wall hanging and includes an upper marginal border area 12 and a lower marginal area 14. In situations where a frame is not present, the edge area of the wall hanging itself will provide the marginal border area.

The apparatus of the present invention comprises a pair of knob members, each referenced 16, and an elongated wall bracket member 18 attached to the pair of knob members. The wall bracket member 18 includes openings 20 through which screws 17 (FIG. 3) or other fastening devices may be passed to attach the knob members 16 and bracket member 18 to the wall surface. A back surface 22 of bracket member 18 is generally planar to allow it to fit flat against the wall surface. The knob members 16 are securely fastened to the bracket member 18 such as by glue or the knob members and bracket member may be formed from a single piece of material such as plastic; as shown in FIG. 4.

Each knob member is generally symmetrical about an axis therethrough and comprises an outer circular lip portion 24 and center cylindrical barrel portion 26 of reduced diameter relative to the circular lip portion 24. When attached to the bracket member 18, the central axis of the knob member 16 protrudes outwardly from the bracket member 18 preferably perpendicularly to the back surface 22 and the wall surface. The bracket member 18 thus comprises one form of means for mounting the pair of knob members at the wall surface generally in an outward protruding and spaced apart relationship. As is shown in FIG. 2, it is desirable that the knob members assume a horizontally spaced apart relationship, which can be achieved by attaching the wall bracket member 18 generally horizontally on the wall surface.

Suspension means for suspending the wall hanging at its lower marginal border area 14 from the pair of knob members 16 also comprises a portion of the apparatus.

The suspension means may take the form of a cable member 28 having a middle portion 30 and two end portions each referenced 32. The middle portion 30 of the cable means is adapted for looping between or encircling the pair of knob members 16 to provide at least one complete loop around the knob members. Each complete loop around the knob members 16 is defined by extension of the cable member from a point on the cylindrical barrel portion 26 of one knob member 16 over the cyclindrical portion of the other knob member and back to the starting position at the cylindrical portion 26 of the first knob member. One end portion 32 of the cable member 28 depends from each knob member 16 and extends downwardly from that knob member to the lower marginal border area 14 of the wall hanging or the lateral edge of the wall hanging vertically closest below the knob member 16. Means for attaching the end portions 32 of the cable member 28 to the wall hanging at laterally opposite positions on the lower marginal border area 14 are provided in the form of eye screws 34 to which the end portions 32 may be connected or tied. In practice, an additional fractional part of a complete loop of the middle portion 30 of the cable member 28 will always exist between the knob members 16 since each cable end portion 32 depends from a different knob member.

The apparatus of the present invention also includes connecting means for connecting the wall hanging at an upper marginal border area 12 to the middle portion 30 of the cable member 28 intermediate the pair of knob members 16, and such means may take the form of a connecting member 36, such as a resilient coil spring member. A hooked-shaped end portion 38 of connecting member 36 serves as one form of means for connecting one end portion of the connecting member 36 to the middle portion 30 of the cable member 28 at the approximate mid-point between the knob members 16. Another eye screw 34 is one form of means for attaching the other end of the connecting member 36, which may also be hooked-shaped, to the upper marginal border area 12 at a position approximately vertically above the mid-point between the points of attachment of the end portions 32 to the lower marginal border area 14. Each of the eye screws is screwed into the frame or otherwise attached to the wall hanging. The connecting member is thus one form of means for operatively connecting the upper marginal border area of the wall hanging to the wall surface.

In use, the pair of knob members 16 is mounted on the wall surface by the wall bracket 18 or other suitable mounting means. The distance between the knob members is selected to be slightly less than the width of the wall hanging, as is shown in FIG. 2. The middle portion 30 of the cable member 28 is looped preferably in a plurality of loops between the pair of knob members, and one end portion 32 of the cable member 28 is caused to extend generally downward from each knob member. The end portions 32 of the cable member are attached to the lower marginal border area of the wall hanging at horizontally spaced positions, as by means of the eye screws. At a position essentially centered between and vertically above the attachment positions of the cable ends 32, the wall hanging is connected to the middle portion 30 of the cable member 28 between the knob members 16 by the connecting member 36. The wall hanging is leveled or set to a desired orientation by lifting the lower edge of the wall hanging and pulling downward at an appropriate location on the opposite upper edge of the wall hanging to cause the middle portion 30 of the suspension cable to slide around the center cylindrical portions 26 of the knob members 16 until the desired orientation is obtained. The connecting member 36 holds the upper portion of the wall hanging slightly outward from the wall surface thereby providing a desired degree of tilt with respect to the wall surface.

If the wall hanging should be accidently bumped or otherwise inadvertantly disturbed, the weight of the wall hanging and the resistance of the coils or loops around the knob members prevent the loops of the middle portion 30 of the cable member 28 from slipping around the cylindrical portions of the knob members, thereby maintaining the picture in its desired orientation. The wall hanging may move slightly from side to side when disturbed but the desired orientation is not changed when the movement stops. Greater resistance to slipping by each loop of the cable middle portion around the knob member 16 is obtained by additional numbers of loops of the cable middle portion around the knob members, but generally three loops of the cable middle portion around the knob members is sufficient.

The preferred embodiment of the invention has been described with particularity so as to enable its clear understanding. However, the scope of the present invention is intended to be limited only according to the inventive concepts expressed by the following claims and only insofar as the prior art requires.
