Abstract
Abstract A flat plate is attached to a wall upon which a picture is to be hung. A pedestal extends outwardly perpendicularly to the wall, and a circular lip with a convexly curved outer surface is attached to the outwardmost end of the pedestal. Ball bearings are located at regular intervals around the lip. A second flat plate is attached to the back of a picture, directly above the center of gravity of the picture. A flexible, circular hollow rim with a convex outer surface and a concave inner surface is attached to the second plate, and can be detachably secured over the lip.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
158 words
A device for hanging flat pictures upon a wall and maintaining the pictures in a level position, comprising: A first flat plate attached to the wall; a pedestal attached to the plate and extending outwardly away from it perpendicularly to the wall; a circular lip located at the outwardmost end of the pedestal, the lip lying in a vertical plane and having a convexly curved outer surface; a second flat plate attached to the back of a flat picture and located directly above the center of gravity of the picture; and a flexible circular hollow rim with a convex outer surface and a concave inner surface attached to the second plate, the rim occupying a plane parallel to the plane of the picture and detachably fitting over the lip so as to enable the picture to be secured parallel to the wall while being free to rotate parallel to the wall and thereby reach a level equilibrium position.
Claim 2
Independent Claim
158 words
A device for hanging flat pictures upon a wall and maintaining the pictures in a level position, comprising: A first flat plate attached to the wall; a pedestal attached to the plate and extending outwardly away from it perpendicularly to the wall; a circular lip located at the outwardmost end of the pedestal, the lip lying in a vertical plane and having a convexly curved outer surface; a second flat plate attached to the back of a flat picture and located directly above the center of gravity of the picture; and a flexible circular hollow rim with a convex outer surface and a concave inner surface attached to the second plate, the rim occupying a plane parallel to the plane of the picture and detachably fitting over the lip so as to enable the picture to be secured parallel to the wall while being free to rotate parallel to the wall and thereby reach a level equilibrium position.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein a plurality of like ball bearings are located at regular intervals around the outer surface of the lip.
