This invention is directed to a suspension system for hanging of pictures, mirrors, or other articles on a wall in a level orientation.
Usually, a device to hang a picture frame on a wall consists of a loop of wire attached to the back of the frame with two eye screws plus a wall mounted hanger. The loop of wire is placed over the wall hanger projection and the frame is leveled manually. The problem with this support system is the frame must be manually returned to level each time the article is touched for dusting or cleaning.
U.S. Pat. No. 4,244,549 by C. T. Oldfield, discloses a wall hanging device which has a rectangular plate with three, equally spaced holes on a horizontal centerline. A loop of wire is threaded through the outer holes and the ends of the wire are attached to the frame. A wall support nail through the center hole supports the plate and frame assembly. After initially leveling the frame, friction maintains the frame in a level attitude. However, if the frame is tilted, friction will maintain the tilted attitude.
U.S. Pat. No. 5,437,429 by J. Atlas, discloses a picture hook hanger, is comprised of a wall anchored retention member and an object holding member. The wall-anchored member comprises means for permitting the fixed position anchoring thereof to a wall with a nail. The object holding member comprises means for holding objects thereon, preferably with two hook elements and a means for permitting floating engagement with the nail. Draping the wire on the back of the frame over the hooks and adjusting the picture to level completes the installation. A problem with this design is that the friction of the wire on the hooks is the force that holds the picture level. If the picture is moved, the center of gravity of the frame may be such that the picture does not hang level.
U.S. Pat. No. 6,318,698 B1 by C. Hansen, discloses a suspension device comprising a base element which is fastened to the backside of a picture frame, an elongated element and a positioning structure for adjustable positioning of the elongated element relative to the base element. Normally, two suspension devices are used per frame. The emphasis of the Hansen invention is on the structure for adjustment of the elongated element. No description of the wall support member is provided. Also, no description of the complete support system is shown in the nine figures.
The current invention overcomes the shortcomings of the above disclosures.
The following is a list of items called out on
When the two washers (110) of the two suspension elements (105) are mounted on the hangers (113), which are attached to a wall (116), the frame (115) will hang level. The frame (115), when touched accidentally, or for dusting will automatically return to level.
