Claims

[Scope of Claim for Utility Model Registration] (1) Consisting of a door handle fixed to a door and a lock case, a latch head provided to be retractable and reversible from the front of the lock case, and a latch head that engages with the latch head. A reversing latch mechanism having a locking member that prevents reversal, a lever that releases the engagement between the latch head and the locking member, and a cam plate that rotates to the locking and unlocking positions to project and retract the dead bolt. In the door lock provided in the lock case, a foot lever is pivotally connected to the lock case and has one end tilted by being pushed by the cam plate rotated to the unlocked position, and a middle portion is pivotally connected to the lock case, a turn plate A having a pushed part that can protrude into the door handle insertion hole provided in the lock case and an engaging pin at one end; a turn plate B having a projectable pushed portion and having one end pivotally connected to the other end of the turn plate A; and a push member slidably provided within the lock case and capable of engaging with the lever. a push plate having a push plate; a hook plate which is pivotally connected to the push plate and whose hook portion at the other end engages with the engagement pin when one end is pushed by the tilting movement of the foot lever; A door lock comprising a spring biased in a direction away from the lever. (2) Consisting of a door handle fixed to the door and a lock case, a latch head provided to be retractable and reversible from the front of the lock case, and a locking member that engages with the latch head to prevent the lock case from reversing. In the door lock, the lock case is provided with a reversing latch mechanism having a lever for disengaging the latch head and the locking member, and a cam plate that rotates to the locked and unlocked positions to move the dead bolt in and out. , a foot lever which is pivotally connected to the lock case and whose one end tilts when pushed by the cam plate rotated to the unlocked position; and a joint arm which is pivotally connected to the lock case on one side and has a connecting pin on the other side. a turn plate having an intermediate portion pivotably attached to the lock case, a pushed portion capable of protruding into a hole for inserting a door handle provided in the lock case, and a turn plate having one end pivotably attached to the other side of the joint arm. A, a turn plate B having an intermediate portion pivotably attached to the lock case, having a pushed portion that can protrude into the insertion hole, and having one end pivotably attached to the other end of the turn plate A; a push plate that is slidably provided in the lock case and has a pushing piece that can be engaged with the lever; and a push plate that is pivotally connected to the push plate and has one end when pushed by the tilting of the foot lever; A door lock comprising a hook plate whose hook portion engages with the engagement pin, and a spring which biases the joint arm to rotate in a direction in which the engagement pin pushes the hook portion.
