  • Patent number: 4244549
    Abstract: A self straightening hanger is rectangular in shape with three holes located on the horizontal center line equally spaced. The outboard holes are used to thread the existing wire at the back of the picture through these holes and provide a means of retaining the wire in a desired preadjusted position. The center hole when placed over the nail supports the picture on the wall and provides a pivot allowing the picture to swing freely. Two rollers each with a length of cord attached to one end of each roller are suspended from the outboard holes of the hanger to a point between the wall and the bottom of the picture frame, in order to remove friction between the picture frame and the wall and allow the picture to return to a straight position should the picture be accidently moved.
