Claims

[Scope of utility model registration request]

A lock piece 1 is provided on the door 2 and moves almost horizontally, and the front end portion 1a of the lock piece 1 is attached to a fixed wall 4. The first arm 7 is rotatably attached along the door surface by a free shaft 10, and one end is rotatably mounted along the door surface by a fixed shaft 11 located approximately on the extension line of the base side of the lock piece 1 on the door 2. The other ends of the second arm 8 are rotatably connected to each other by a connecting shaft 12, and the lock piece 1 is pulled toward the fixed shaft 11 of the second arm 8 and removed from the lock piece receiver 5. A lock piece pulling mechanism 6 in which both ends of a coil spring 9 for pulling out are attached to intermediate positions of the first arm 7 and the second arm 8, respectively.
, the first arm 7 and the second arm 8 are moved between the free shaft 10 and the fixed shaft 11 against the tensile force of the coil spring 9.
One end is rotatably connected to the connecting shaft 12 and moves up and down in order to move the lock piece 1 toward its tip and insert it into the lock piece receiver 5 by positioning it on the opposite side to the line connecting the two. A shaft 13 provided substantially vertically; a pedal mechanism 14 attached to the lower part of the door 2 and connected to the lower end of the shaft 13 to alternately move the shaft 13 in the vertical direction; It is characterized by mainly comprising a stopper 20 for stopping the movement of the lock piece 1 due to the tensile force of the coil spring 9 which is applied after the first arm 7 and the second arm 8 exceed the linear state when moving in one direction. door lock mechanism.
