Since it is necessary to have enough brightness to read the number, it is impossible to read the number in a place where the brightness is insufficient and the lock cannot be opened. In addition, the support shaft that separates the lock ring and the ratchet ring of each set when setting a password,
Since the operation end of the lock box is exposed outside the lock box, it is necessary to project the operation end to the inside of the room, which is shielded from the outside, in order to install the operation end so as not to be operated unnecessarily. . In addition, since the reset member having the projection that engages with the lock ring is connected to the door latch such as the knob, the use thereof is limited only to the door, and the cost is increased due to the complicated lock mechanism. There is also a disadvantage.

決すべき課題となっていた。On the other hand, in the case of bicycle locks as well, there has been a demand for the development of locks in which the number for unlocking, that is, the setting of a personal identification number can be arbitrarily set according to the user's preference. Therefore, even in a place without lighting, the number of push button operations can be matched with the password to enable the unlocking operation only by fumbling, and the structure can be simplified and the cost can be reduced. It has been a problem to be solved that this type of push button type lock can be adopted also for a bicycle lock by preventing the number from being operated.

7 is engaged. Each click spring 9 rotates integrally with the support shaft 6 by fitting an engagement piece 28 projecting from the ring-shaped inner surface into a long groove 29 on the side surface of the support shaft 6. The ratchet ring 8 and the lock ring 7 rotate in the same direction when rotating in the direction in which the arc-shaped tip 27 faces, and in the case of rotation in the opposite direction, only the click leaf springs 9 resiliently hit the concave and convex portions 26. It spins while emitting and prevents the search performed by rotating the unlocking operation member 12.

うになる。When the lock of the first embodiment configured as described above is unlocked from the locked state, the unlocking operation member 12 is moved in the direction in which the arc-shaped tip 27 of the click spring 9 faces.
After turning the convex portion a to the reset position 30 by rotating it by at least rotation, each push button 2 is pressed a predetermined number of times. Thereby,
The ratchet ring 8 rotates one tooth at a time when the push button 2 is pressed down, and rotates the lock ring 7 located at the zero point to a predetermined position via the engagement portions 20a and 20b. In this state, the unlocking notch 23 of each lock ring 7 matches the projection 24 of the reset member 13 as shown in FIG. 3, so that the unlocking operation member 12 is pressed against the restoring spring 14 as described above. And the latch 19 can be moved to the unlocked position against the repulsion spring 18.

れることを防止している。When the password of the lock is to be changed, the unlocking operation member 12 is similarly turned one or more turns so that the projection a coincides with the reset position 30, and then the opening at the end face of the unlocking operation member 12 is opened. When a rod corresponding to the inner diameter is inserted from 31 and the support shaft 6 is pushed in, each ratchet ring 8 is pushed by the projection 35 and moves to the right against the return spring 10 and separates from the lock ring 7. Therefore, only the ratchet ring 8 becomes rotatable. Further, after the push button 2 is pressed a desired number of times, if the support shaft 6 is released, the meshing position of the ratchet ring 8 and the lock ring 7 which have been restored changes, and the password is newly changed. It will be set. As described above, in this lock, the operation part for unlocking and the operation part for setting the personal identification number can be formed in the same part, and the shaft end of the support shaft 6 operated for setting the personal identification number is It is shielded in the unlocking operation member 12 and does not appear on the external appearance, thereby preventing the operation from being sloppy.

After turning the unlocking operation member 12 one or more rotations in a predetermined direction to match the reset position 30 as in the first embodiment,
When each push button 2 is pressed a predetermined number of times, the ratchet ring 8 and the lock ring 7 rotate integrally, and the unlocking notches 23 are moved to the engagement positions with the projections 24 of the reset member 13 as shown in FIG. Thus, the unlocking operation member 12 can be pressed. In FIG. 5, when the unlocking operation member 12 is moved to the right hand in the figure, the window-shaped latch 19 formed in the reset member 13 also moves to the right hand to release the locking of the free end Y2 of the wire Y. The free end portion Y2 is pushed out of the insertion hole 32 by the elasticity of the push plate 33 and the coil spring.

When a rod or the like is inserted through the opening 31 on the outer end surface and the key 21 is guided by the groove 22 and the support shaft 6 is pushed to the position shown in FIG. 5, the engagement portions 20a and 20b of the lock ring 7 and the ratchet ring 8 are separated. Therefore, if each of the push buttons 2 is pressed a desired number of times and returned, the number of times becomes a new password as in the case of the first embodiment, and the unlocking is performed by the password from the next time onward.

用錠に採用できるようにしたという実用的効果がある。As described above, according to the present invention, a plurality of sets of ratchet rings and lock rings having circumferentially engaging portions on the end faces abutting each other are provided together with a click spring for searching and stopping in a lock box. Rotatably fitted on the support shaft,
The support shaft is provided with a projection that separates each set of ratchet rings from the respective lock ring against the return spring, so that an arbitrary unlocking position can be set on the lock ring, and By fitting the engagement piece on the inner periphery of the click spring into the long groove of the side surface of the support shaft, each of the sets of rings is provided so as to rotate in conjunction with one-way rotation of the support shaft, while each lock ring is provided. A latch is connected to one end of a reset member for engaging the projection with the unlocking notch, and a cylindrical unlocking operation member rotatably connected to the other end of the reset member is provided for enabling pushing into the lock box. In this unlocking operation member, the outer end of the support shaft is fitted so as to freely slide in the axial direction and rotate integrally with the unlocking operation member. Since the reset position is provided on the member, it has been used only as a lock for the door latch. The structure of this type of lock that could not be used was simplified, the unlocking operation and the setting of the security code can be performed in the same part, and the outer end of the support shaft for setting the security code is shielded inside the unlocking operation member As a result, even when used outdoors, it can be used safely without being deliberately operated, and can be unlocked only by counting the number of times of operation of the push button, so that it can be used in a place without lighting. The present invention has the practical effect of improving the lock in which the personal identification number can be set arbitrarily as described above and adopting the lock in a bicycle lock.
