  • Patent number: 7891056
    Abstract: A locking door hinge for securing a door in a fixed position, such as closed, partially open or fully open. In one embodiment, the locking door hinge is configured similar to a butt hinge having a pair of generally rectangular leaves with barrels at the proximal end thereof and a pivot pin that passes through the barrels to pivotally connect the leaves together. To prevent movement of the door, the locking door hinge has a locking pin that is received in a locking socket which is disposed in at least the top two adjacent barrels. In a preferred embodiment, the locking socket is disposed in each of the barrels such that the locking pin extends from the first end to the second end of the hinge. If desired, a plurality of locking sockets can be provided to allow the user to fix the extent to which the door is open.
