BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dial lock device installed at a door portion of a rental locker, a safe deposit box, and the like, and more particularly, the present invention relates to a dial lock device that enables an arbitrary unlock number to be set by a dial operation.

For example, a number of rental lockers are installed in various facilities such as golf courses. Each rental locker has a lock that can be used to correct the door with its own key. However, this type of lock is easy to lose the key because the user must carry the key, causing problems. Therefore, although the introduction of the keyless dial lock device has been considered, there is a fear that the lock key device in which the lock code is fixed for each lock will be unjustly unlocked if the lock number is known to another person.

In order to cope with this problem, a dial lock device has been proposed in which a user can set a lock number from time to time.

The dial lock device of the kind shown in FIG. 31 includes an operating mechanism 102 having an operating handle 101 for reciprocating the locking means 100 in the direction of an arrow in the figure, and the operating mechanism 102. The dial lock 104 is provided with three dials 103 for forming a locked state in which the operation of? Is restricted.

The dial lock 104 makes it possible to set the unlock number when the lock 100 is in the unlocked position shown in the figure. When the lock 100 shifts to the corrected position indicated by the dashed line, the lock number is stored. The structure includes a unlocking number setting mechanism which makes it possible, and a locking mechanism which forms a locked state by dispersing the alignment of the unlocked number after the catch 100 moves to the corrected position.

In the dial lock apparatus having such a structure, the user first operates the three dials 103 individually to align the desired unlock numbers. In the illustrated example, the set unlock number is '1' '1' '1'.

Next, the operation knob 102 is turned to operate the operation knob 101, and the clamp 100 is rotated to the correct position to be coupled to the receiving key (not shown). The set unlock number becomes a memorable state in this state.

Next, when the three dials 103 are operated separately to disperse the alignment of the unlock number, it becomes a locked state and the operation knob 101 cannot be turned.

However, in such a dial-lock device, the user may set the unlock number to rotate the operation knob 101 and then leave the unlocked number unsettled because it is not scattered. In this state, when the other person operates the operation knob, the lock is returned to the unlocked position, and the locker can be opened improperly.

In order to cope with this problem, introduction of a mechanism for forcibly dispersing the set unlocked number when the operation knob 101 is rotated after setting the unlocked number has been considered. And cost increases.

The dial lock device of the present invention is provided with an operation mechanism for reciprocating the lock, and a dial lock for forming a locked state in which the operation of the operation mechanism is regulated, wherein the dial lock is unlocked when the lock is in the unlocked position. The unlocking number setting mechanism which makes the setting of the number possible, and makes it possible to store the unlocking number when the lock is shifted to the corrected position, and the corrected state by dispersing the alignment of the unlocked number when the lock is shifted to the corrected position. It is provided with a correction mechanism to form a.

The invention of claim 1 further includes a confirmation operation mechanism that operates by an external operation in addition to the above-described configuration, and an operation of the confirmation operation mechanism when the lock is in the correct position and the corrective state by the correction mechanism is not formed. And a return mechanism for forcibly returning the lock to the unlocked position by correspondingly operating the operation mechanism.

In this dial lock device, the lock number is set by dial operation, and then the lock is operated to the locked position by the operating mechanism. Then, after disassembling the alignment of the unlock number, the correcting state is formed by the correcting mechanism, and the confirming operation is performed by the confirming operation mechanism. If the confirmation operation is performed without disturbing the alignment of the release number, the return mechanism forcibly operates the operation mechanism to force the lock back to the unlocked position. This return operation makes it possible to recognize that the operation of dispersing the unlock number is omitted, thereby improving the safety of the dial lock device.

According to the invention of claim 2, in addition to the configuration described in claim 1, the dial lock of the dial lock is inoperable when the check operation mechanism is operated in a state in which the lock is in the correct position and the lock state is formed by the correcting mechanism. A dial operation regulating mechanism is provided.

In this dial lock device, when the confirmation operation is performed in a state where a locking state is formed, the dial operation control mechanism puts the dial of the dial lock in an inoperable state. This makes it possible to recognize whether or not the corrective state is in the correct state simply by checking whether the corrective operation is possible.

According to the invention of claim 1, a check operation mechanism operated by an external operation is provided so that the operation mechanism corresponds to the operation of the check operation mechanism when the clamp is in the correct position and the state of correction by the correcting mechanism is not formed. Since the lock is forced to return to the unlocked position, if the forget operation of the lock number is forgotten and the check operation mechanism is operated, the return mechanism is forcibly returned so that it can be easily recognized that the lock number has been removed. The safety of the dial lock device can be improved.

In the case of unlocking, the lock is automatically returned to the unlocked position by the operation of the check operation mechanism, so that the unlocking operation becomes easy.

In the invention according to claim 2, the dial lock is placed in an inoperable state when the check operation mechanism is operated when the lock is in the correct position and the state of correction by the correcting mechanism is formed. Just by checking whether it is possible, there is an effect of easily recognizing whether or not it is in a corrected state.

When excessive force is applied to the operation knob 9, the tip portions of the urine pieces 75 and 75 are deformed by being pressed against the outer circumferential wall surface of the coupling groove 78, so that the coupling member 71 is integrally rotated with the operation knob 9. Thus, the operation handle 9 is idle with respect to the operation shaft 12.

Next, operation | movement of the dial lock apparatus 1 of the said structure is demonstrated.

First, when the clamp 5 is in the unlocked position, the tip of each of the actuating shaft 23 and the bush 24 is in a state of being inserted into the first recess 25a of the cam body 22 at the same time, and the actuating shaft 23 Each of the protrusions 30 is coupled to the projection engaging groove 36 of each lock gear 27 is entered. At this time, each dial 11 is not engaged with the lock gear 27 so that the unlock number can be set and the rotation is free (FIGS. 5 and 8).

On the other hand, the pin 56 of the push button 10 is located in the communication position of the 1st peripheral groove part 57a and the 1st shaft groove part 57c of the cam body 22 (FIG. 21).

Next, by operating each of the dials 11 in the free rotation state, arbitrary unlock numbers are aligned as shown in FIG. 28 to set unlock numbers. The unlock number set in the illustrated example is '1' '2' '3'.

After setting the unlocking number, turning the operation knob 9 in the locking direction rotates the clamping mechanism 5 integrally with the operation shaft 12 and is engaged with the receiving clamp 6 during the rotation. In this rotation, the tip of the actuating shaft 23 and the bush 24 escapes from the first recess 25a of the cam body 22 and rides on the circumferential surface of the cam body 22, so that the actuating shaft 23 and the bush 24 24 is pressed by the spring force of each of the first and second springs 26 and 29, and each lock gear 27 successive to the bush 24 is pressed in the same manner, so that each lock gear 27 When the dial 11 corresponding to is engaged, the set unlock number can be stored (Fig. 9).

On the other hand, the pin 56 of the push button 10 slides the first peripheral groove portion 57a of the cam body 22 by the rotation of the operation knob 9.

As shown in FIG. 29, when the locking knob 5 reaches the first locking position as shown in FIG. 29, only the tip of the operating shaft 23 has the second recess 25b of the cam body 22. As shown in FIG. Each projection 30 on the operating shaft 23 escapes from the projection engaging groove 36 of each lock gear 27. In this state, each projection 30 is not engaged with the projection engaging groove 36 of each lock gear 27 (FIGS. 6 and 10).

On the other hand, the pin 56 of the push button 10 has reached the communication position of the first peripheral groove 57a and the second shaft groove 57d, and the stopper pin 61 is caught in the pin hole 62 at this time. The cam body 22 is restrained (FIGS. 22 and 23).

Next, by operating each dial 11 to disperse the alignment of the set unlock number, for example, as shown in FIG. 30, the number of each dial 11 is set to '0' '0' '0'. The angular position of each projection 30 on the lower surface of the actuating shaft 23 and the angular position of the projection engaging groove 36 of the corresponding lock gear 27 are shifted.

Next, when the push button 10 is pressed, the pin 56 of the push button 10 moves the second shaft groove portion 57d downward and pushes the stopper pin 61 to escape from the pin hole 62. As a result, since the cam body 22 is restrained, the operation shaft 12 is rotated in the release direction by the spring force of the return spring 60, and the pin 56 slides the second peripheral groove portion 57d.

Thus, when the operating shaft 12 is rotated by 30 degrees, the tip of the operating shaft 23 moves from the second recess 25b of the cam body 22 to the third recess 25c. 23 is pushed back slightly, so that each projection 30 on the actuating shaft 23 engages with one projection engaging groove 36 of each lock gear 27. As a result, the catch 5 is brought into the second locking position, and the lock gear 27 is restrained, so that the operation of the dial 11 is impossible (Figs. 7 and 11).

When the operation shaft 12 is rotated 30 degrees, the pin 56 of the push button 10 is engaged with the pin coupling portion 64 of the cam body 22 (Fig. 24).

If the push button 10 is operated without disengaging the unlock number when the catch 5 is in the first locking position, the pin 56 of the push button 10 moves the second shaft groove portion 57d downward. By moving and pushing in the stopper pin 61, it escapes from the pin hole 62, and the cam body 22 is released from restraint. As a result, the operation shaft 12 is rotated in the release direction by the spring force of the return spring 60, and the pin 56 slides the second peripheral groove portion 57b. In this case, since each projection 30 on the operating shaft 23 and the projection engaging groove 36 of each lock gear 27 have the same angular position, the projections 30 are formed of each lock gear 27. It enters into the projection engaging groove 36, and the return operation by the return spring 60 of the operation shaft 12 is not blocked in the middle, and the clamp 5 returns to the unlocked position.

On the other hand, the pin 56 of the push button 10 slides the second peripheral groove 57b without engaging the pin coupling portion 64 of the cam body 22 to communicate with the first shaft groove 57c. After reaching, the push button 10 is pushed up by the spring force of the spring 53 so that the pin 56 returns to the initial position.

Next, to release from the correcting state, first, the operation knob 9 is turned 30 degrees in the correcting direction to set the catch 5 at the second correcting position. As a result, the engagement between the protrusions 30 on the operating shaft 23 and the protrusion coupling holes 37 of the lock gears 27 is released, and the lock gears 27 are released from the restraints, thereby allowing the operation of the dial 11. Become.

Then, by aligning the unlock number by operating the dial 11, each projection 30 on the right side of the operating shaft 23 and the projection engaging groove 36 of each lock gear 27 have the same angular position as the push button 10. As described above, the operation shaft 12 is rotated in the release direction by the spring force of the return spring 60, and each projection 30 is squeezed into the projection engaging groove 36 of each lock gear 27 to stop. The iron 5 returns to the unlocked position.
