Claims

[Scope of utility model registration request]

The locking shaft 5 of the handle body 4 is rotatably and slidably fitted in the bearing cylinder part 3 of the catch seat 2 fixed to the door 1, and is engaged with and disengaged from the receiving part 6 of the fixed frame 8 to close the door. A stop plate 7 for locking and unlocking the locking shaft 5 is fixed to the locking shaft 5, and a locking rod 11 is inserted into the cross hole 10 of the locking shaft 5, and the rotor 1 of the lock 12 provided on the handle body 4 is fixed.
3 is interlocked with the locking rod 11, and a locking groove 14 is provided on the inner surface of the bearing cylinder portion 3, with which one end portion 11a of the locking rod 11 engages when the stopper plate 7 is in the locked position. When the lock bar 11 is rotated with the key 19
The receiving groove 15 with which the other end 11b engages is inserted into the locking groove 1.
4 on the inner surface of the bearing cylinder part 3, and when the stop plate 7 is in the unlocked position, the other end 1 of the lock rod 11
A stop groove 16 with which the lock 1b engages is provided on the inner surface of the bearing cylinder part 3 via the partition wall part 17, so that when the handle body 4 is slid toward the catch seat 2, the lock bar 11 engages with the stop groove 1.
This unlocking position restraining type lock handle device for a door has an axial length of a partition wall 17 set so as to escape from a door 6, and a handle body 4 is biased to slide in a direction away from a catch seat 2 by a spring 18.
