1. A vertical door latch assembly comprising:
a housing configured to be attached to a door;
a bolt assembly comprising a bolt which is positioned at least partially within the housing and is slidable relative to the housing to allow the bolt to be extended from the housing and to an extended position configured to engage the bolt with an aperture in a guide rail of the door. wherein the bolt is configured to prevent movement of the door relative to the guide rail when the bolt is engaged with the aperture;
a lock member comprising a pin positioned within the housing and moveable between a lock position where a portion of the pin is received within a pin opening in the bolt, and an unlock position wherein no portion of the pin is received within the pin opening, wherein when in the lock position the pin locks the bolt in the extended position relative to the housing;
a slider having at least one abutment surface that engages the pin when the pin is in the lock position and retains the pin in the engaged position relative to the pin opening in the bolt;
a driver that rotates a drive member to move the slider along a linear path between at least
a first position wherein the at least one abutment surface of the slider engages the lock member and retains the portion of the pin within the pin opening in the bolt, and
a second position wherein the at least one abutment surface moves out of engagement with the lock member, the second position configured to allow the pin to move to a position where no portion of the pin is received in the pin opening in the bolt; and
wherein, once no portion of the pin is received within the pin opening, the bolt is moveable to retract further into the housing in order to allow the bolt to be disengaged from the aperture in the guide rail of the door and thereby allow movement of the door relative to the guide rail.
