  • Patent number: 8161601
    Abstract: The invention relates to a door hinge system which includes an integral exposed vertically oriented pin as a portion of a doorframe bracket, and a central latch bracket as engaged to a door. The pivotal manipulation of the door engages the latch of the central latch bracket to the pin, to secure the door to the doorframe. The central latch bracket includes a channel for receipt of the pin which is securely and releasably retained in the channel by the leading cam edge of the latch and safety slide. Disengagement of the latch from the pin enables a door to be easily separated from doorframe for re-hanging at a future time.
