Claims

[Scope of Claim for Utility Model Registration] (1) A lock case installed in the end of the door, an inverted latch head unit fixed in the lock case and having a tiltable arm at the rear end, and the lock case. a push plate that is slidably provided on the body and has a pushing piece that tilts the arm by sliding; a joint arm that has one side pivoted to the lock case and the other side pivoted to the push plate; , a turn plate A whose middle portion is pivotally attached to the lock case, has a pushed portion adjacent to one side of the insertion hole of the tip of the door handle, and whose one end is pivotably attached to the other side of the joint arm; and a turn plate B having an intermediate portion pivotally connected to the lock case, having a pushed portion adjacent to the other side of the insertion hole, and one end being pivotally connected to the other end of the turn plate A; A door lock comprising a spring that biases the pressed portions of turn plate A and turn plate B in the direction of the insertion hole and biases the pushing piece in the direction away from the arm. (2) The reversible latch head unit is composed of a cylindrical body and a front wall having an opening for the latch head to emerge and retract, a latch guide that is fixed to the lock case, and a latch guide that is inserted into the latch guide and can be retracted and retracted from the opening for the latch head to emerge and retract. and a latch head which is reversibly provided, has a locking surface and a slope formed at its tip and a locked portion at its rear end, and is biased in a direction protruding from the opening for projecting and retracting the latch head, and the latch guide plate. A locking member is provided movably within the latch guide plate and is biased in a direction in which the locking portion at the tip engages with the locked portion; 2. The door lock according to claim 1, further comprising a lever having a distal end portion for pushing the locking member in the opposite direction and an arm projecting from the rear end of the latch guide.
