  • Multi-position door hinge lock
    Patent number: 5642910
    Abstract: A non-destructible, multi-position hinge lock to be coupled to the existing hinge assembly of a door so as to be capable of reliably retaining the door in either an opened or closed position relative to a doorway. The hinge lock has a hollow interior in which to receive the hinge pin of the existing hinge assembly of the door. A first longitudinal channel is formed in the hinge lock in which to receive the pair of hinge plates of the existing hinge assembly when the door is rotated to a closed position and the hinge plates are correspondingly rotated into face-to-face alignment with one another. The hinge lock includes second and third longitudinal channels formed therein in which to receive respective ones of the hinge plates when the door is rotated to a first opened position and the hinge plates are correspondingly rotated to form an angle of 90 degrees.
