That is, the knob 8 of the operating mechanism 6 is interlocked with the drive pinion gear 14 and the sector gear 41, the gear 41 is rotated about the bin part 42, and the interlocking pin 43 moves the slide 21 with the spring 36.
The locking mechanism 16 prevents the door 2 from sliding against the door 2, so that the locked state is maintained and the door 2 cannot be opened.

Even if the knob 8 is forcibly opened in the unlocking direction, the safety mechanism 13 works, the knob 8 only rotates idly, and the interlocking pin 43 does not swing.

Therefore, to open the lock, press multiple push buttons 33 from 1 to 0 and
A plurality of combinations of Yz push buttons 33 are set in advance to the tumbler 2.
The slide 21 can only be slid when it is aligned to unlock in the set state of 4. Therefore, the resident memorizes the combination alignment number and presses the push button 33 corresponding to the number. The tumbler 24 is pushed in against the spring 34, and the tumbler 24 is pushed in against the spring 28, and the pushed tumbler 24 is removed from the clear actuating body 17.
The engagement groove 29 is engaged with the protruding portion 25 of the spring 26 to maintain the position.

If you press a number other than the one stored by mistake, press the push button 33 that corresponds to the clear tumbler 24'' and move the clear actuating body 17 in the clear direction (in the upward direction in Fig. 4) with the cooperation of the cams 35 and 38. ), align the positions of the tumbler 24 and the spring 26 relative to each other, and clear the tumbler 24 via the spring 28. In addition, after pressing the push button 33 of the memorized number as memorized, , the pushbutton 3
3 is returned to its old position by a spring 34.

When the locking mechanism 16 is unlocked, the interlocking pin 43 slides on the slide 21 against the spring 36 via the gear transmission mechanism 40, and the locking machine fill is opened via the latch drive shaft 9. This makes it possible to interlock in the direction of the lock.

Note that after the lock is unlocked, the slide 21 is moved by the spring 3.
At 6, the clear actuating body 17 is pushed in by the spring 27, the tumbler 24 is returned to the old position by the spring 28, and the return of the slide 21 returns the sector gear 41 to the old position via the interlocking pin 43.

Further, since the operation knob 8 can be interlocked with the latch drive shaft 9 in the direction of locking the latch mechanism 1 regardless of the lock mechanism 16, it can be freely locked from the outdoor side.

(Effects of the Invention) The present invention is as described above, and according to the present invention, the locking mechanism 16 can be locked by an arbitrary number by combining and matching the tumblers 24, and at that time, the clearing actuating body 17 is connected to the frame structure. By placing the tumbler 24 in the center of the slide 21, which can be freely positioned, on both sides of the clear actuating body 17, the entire device can be designed very compactly, and is much cheaper in terms of value than the conventional example. Therefore, it is very useful to be able to provide a keyless locking device that operates reliably and is easy to assemble.
