または第(2)項記載のラツチ錠。[Claims for Utility Model Registration] (1) The head has an inclined surface portion (a) and a locking surface portion (b);
A latch 3 is fitted into a lock case 4 and is always biased in the projecting direction by a latch spring 6, and the latch 3 is rotatably and slidably supported on the lock case 4 by a pivot 8. The engaging portion 9 at the rear end of the latch 3 normally engages with the locking portion 5a of the control member 5 to prevent rotation of the latch 3, and when the control member 5 retreats, the latch 3 is engaged. Joint part 9 and control member 5
is disengaged from the locking portion 5a to rotate the latch 3, and at the same time, the engaging portion 9 of the latch 3 is engaged with the engaging receiving portion 13 of the control member 5 to further move the control member 5 backward. By doing so, the latch 3 is formed to be integrally retracted, and the pivot 8 is also
The distance L2 from the pivot point 8 to the engaging portion 9 of the latch 3 is the distance L2 from the receiving hole 2 of the receiver 20 when the latch is locked.
1. A latch lock characterized in that the distance L between the latch and the latch is as long as possible than 1 . (2) A transmission member 16 protruding to the outside of the lock case 4 is connected to the control member 5, and a cable D for a closing body B such as a smoke exhaust window is attached to the transmission member 16. The latch lock described in paragraph (1) of the claims for patent registration. (3) The engaging part 9 of the latch 3 is formed by the rear wall of a notch formed at the rear lower part of the latch 3, and the locking part 5a of the control member 5 is formed by a notch formed at the front upper part of the control member 5. A utility model in which a notch-shaped engagement receiving part 13 is formed on the upper surface of the rear wall, and the lower end of the engagement part 9 is in contact with the locking part 5a to prevent rotation of the latch 3. A latch lock according to registered claim 1 or 2.
