MORTISE LOCK DEVICE OF DIGITAL DOOR LOCK AND DOOR SYSTEM

摘要

A mortise device of a digital door lock and a door system are provided to enhance use convenience by enabling a user to lock and release a door only by using a single handle. A housing(11) is embedded in a door(1). A moving plate(32) elastically moves from a release position inside the housing to a side locking position of the housing and includes a side dead bolt piece. An upper locking rod(40) elastically moves from the release position inside the housing to an upper locking position of the housing and includes an upper dead bolt piece. A lower locking rod(50) elastically moves from the release position inside the housing to a lower locking position of the housing and includes a lower dead bolt piece. A driving unit drives the upper and lower locking rods between the release and locking positions, as the moving plate moves between the release and locking positions. A handle shaft(20) is rotatably installed between a first position of forward direction and a second position of reverse direction on the housing and includes a pressing lever. A locking unit(70) locks the moving plate with the upper or lower locking rod. An automatic locking unit allows the moving plate to move from the release position to the locking position, so that the door is automatically locked.
