Then, a personal identification number consisting of the number of digits corresponding to the number of operation buttons is set or input, and unlocking is enabled by operating a predetermined operation button corresponding to the personal identification number at the time of unlocking (for example, Patent Literature 1).

  However, since this conventional mechanical lock can only input single password information to the operation buttons, there is a limit to the amount of password information that can be input. In addition, there are problems such as an increase in size and weight, making it difficult to secure a space for installation, and worsening the appearance of the door.

  In order to solve such problems, the amount of information for the operation buttons can be increased, a large amount of setting information and its wide selection can be obtained, the defense capability can be improved, the configuration can be simplified, and the size and weight can be reduced. It can be manufactured at low cost, and information can be set or input and changed accurately and safely, easily and rationally, and the setting or input information cannot be decoded or detected. The applicant has developed a button lock that can prevent tampering, and has already proposed this (see, for example, Patent Document 2).

However, this conventional mechanical lock lock has a button gear linked to the operation button, a terminal gear meshable with the button gear, and a reset gear meshable with the terminal gear arranged in the width direction inside the case. Therefore, there are problems such as a wide case, a large number of parts, a large lock and a complicated structure, and an increase in cost.
In addition, an operation hole into which the operation tool can be inserted is formed at a case position coaxial with the terminal gear, and the operation tool is inserted into the operation hole at the time of setting or inputting a password and locking / unlocking. Since the engagement between the button gear adjacent to the terminal gear and the reset gear is temporarily released and the operation button is pressed a required number of times according to the password under this situation, the operability is poor. There was a problem.

When fitted, a screw 61 is inserted and screwed in to connect the operation handle 60 and the drive cam 56.
Then, the pin hole 53 of the lock cover 8 is fitted to the pin 54 of the lock case 7, the shaft portion 57 of the drive cam 56 is inserted into the through hole 55 of the cover 8, and the lock cover 8 is positioned. By the way, the screw 9 is inserted into the screw hole 72 and screwed into the screw hole 73 of the lock case 7, and the lock cover 8 is attached to the lock case 7.

  When attaching the assembled sliding door sickle lock 3 to the sliding door, the mounting plate 69 is positioned at a predetermined height position outside the vertical rod 2, and the screw 71 is inserted into the screw hole 70 from the outside of the mounting plate 69. It is inserted into the through-hole 77 formed in the hook 2, further inserted into the through hole 72 of the lock cover 8, screwed into the screw hole 73 of the lock case 7, and the sliding door sickle lock 3 is attached to the inside of the vertical hook 2. .

This situation is as shown in FIG. 1 and FIG. 4, and the sliding door sickle lock 3 has an elongated columnar shape and is attached compactly without protruding from the downpipe 2, so that the appearance around the sliding door or downpipe 2 is impaired. There is nothing.
In addition, two operation buttons 14 are arranged in a vertical line at the upper center of the sliding door sickle lock 3, a small hole-shaped operation hole 16 is formed at the center of the button 14, and two display windows 68 are opened on the side surface. The display boards 31 and 31 of a predetermined color are exposed on the windows 68 and 68, thereby providing a design aesthetic.

When using such a button lock, first, desired password information is input to the operation button 14 and set.
For convenience of explanation, this will be described in a situation where the password information is first input and set in the button lock. The sliding door sickle lock 3 before the initial setting of the password information is in a state in which the operation button 14 can be locked as shown in FIG. The display board 31 is exposed in the two display windows 68.

Under such circumstances, the two storage buttons 19 are urged forward by the elasticity of the spring 29, and the dog 20 engages with the dog 18 of the button case 15, causing the case 15 to move forward. The front end surface of the button case 15 protrudes from the surface of the lock case 7 and the latching piece 17 at the rear end portion is engaged with the guide rib 13 of the guide ring 12.
Further, the lock cam 36 is positioned coaxially and rearwardly of the memory button 19, the cam 36 is urged forward by the elasticity of the spring 52, one side of the lock button 36 engages with the stepped hole 35 of the partition plate 32, and its corner The shaft 37 is engaged with the engaging groove 26 of the concave hole 25, and the locking groove 39 is positioned vertically downward.

On the other hand, the lock plate 43 is pushed down by the elasticity of the spring 47 as shown in FIG. 4, the bent piece 46 engages with the long side portion 56 a of the drive cam 56, and the locking claw 45 extends from the locking groove 39. The lock cam 36 and the memory button 19 are placed so as to move together.
Further, since the lock cam 36 is located at one side end so that the peripheral edge of the opening window 44 of the lock plate 43 can be engaged and the other end is engaged with the stepped hole 35, the axial direction of the lock cam 36 is increased. The movement of is restricted.

Under such circumstances, the operation handle 60 is first rotated, and the drive cam 56 is moved to engage the short side portion 56 b with the bent piece 46, and the lock plate 43 is resisted by the elasticity of the spring 47. Then, the locking claw 45 is engaged with the locking groove 39, the rotation of the lock cam 36 is prevented, and the button lock is set in the unlocked state.
This situation is as shown in FIG. 23. The opening window 44 of the lock plate 43 moves upward, the opening edge of the window 44 and the lock cam 36 are disengaged, and the lock cam 36 can be moved in the axial direction.

Therefore, the operation tool 67 is held, and the operation pin 66 is inserted into one operation button 14, in the embodiment, the operation hole 16 of the upper operation button 14, and this is inserted into the through hole 22, and the corner of the lock cam 36 is inserted. The shaft 37 is brought into contact with the end surface.
When the operation pin 66 is pushed against the elasticity of the spring 52, the spring 52 is compressed and contracted by the spring receiver 41 as shown in FIG. 24, and the lock cam 36 is moved in the same direction by the displacement, and the other side angular axis 37 moves from the engaging groove 26.
In this case, since the lock cam 36 is prevented from rotating by the locking claw 45 and moves in the axial direction along the locking groove 39, the situation of the angular shaft 37 is as shown in FIG.

Thereafter, the operation button 14 is pressed through the operation tool 67 for the number of times corresponding to the password setting information of the operation button 14.
For example, if the password setting information of the upper operation button 14 is “2”, the operation button 14 is pressed twice. In that case, after pressing once, setting the password information of “1”, pressing once more, setting the password information of “1”, and adding to the password setting information, Password information “2” is set. When the password setting information is “0”, the operation button 14 is operated zero times, that is, before the password information is initially set.

Therefore, the upper operation button 14 is first pressed once through the operation tool 67.
In this case, the operation pin 66 is further pushed in to push and move the lock cam 36, the square shaft 37 is pushed out from the concave hole 25, and the engagement between the square shaft 37 and the engagement groove 26 is released.
If it does in this way, the operation tool 67 will be moved as much as the operation pin 66 is pushed in, and its tip will engage the front surface of the button case 15.
When the operating tool 67 is further pushed in under this condition, the button case 15 is pushed inside the button insertion hole 11 against the elasticity of the spring 29, and the memory button 19 that engages with the dog 18 is moved to this. Then, the rectangular tube portion 24 is pushed into the square hole 28 of the spring receiver 27, and the tip portion enters the stepped hole 35.

On the other hand, when the operation tool 67 is pushed in, the distal end of the operation pin 66 is moved further to the back, the lock cam 36 engaged with the pin 66 is moved, and the lock cam 36 and the spring receiver 41 are locked. Move to the bottom of the eight recessed holes 51.
This situation is as shown in FIG. 25, where the square shaft cylinder portion 24 is further pushed into the square hole 28, and the square shaft 37 comes out of the concave hole 25. For this reason, the engagement between the square shaft 37 and the engagement groove 26 is released, and the storage button 19 can be rotated.

  Next, after the operation tool 67 is pushed in, when it is pulled forward and the engagement with the button case 15 is released, the button case 15 and the storage button 19 are pushed back to the original position by the elasticity of the spring 29, and The lock cam 36 and the spring receiver 41 are pushed back to the original position by the elasticity of the spring 52.

When the memory button 19 returns to the original position, the taper cam 23 of the memory button 19 engages with the taper portion of the guide rib 13, and the memory button 19 rotates helically. A spring receiver 27 fitted to the square shaft cylinder portion 24 rotates synchronously.
The rotation angle between the memory button 19 and the spring receiver 27 corresponds to one pitch of the guide rib 13, that is, 45 °, and the rotation angle is held by the engagement of the dogs 18 and 20.
Accordingly, the display plate 31 is moved by the rotation of the spring receiver 27, and the display plate 31 disappears from the display window 68.

On the other hand, the lock cam 36 is pushed back to the original position, and its angular shaft 37 engages with the engagement groove 26 of the storage button 19 to prevent the storage button 19 or the spring receiver 27 from rotating.
In this case, the square shaft 37 is maintained in the same phase as the initial assembly by the locking claw 45 and the locking groove 40, while the memory button 19 is rotated by 45 ° from the initial state as described above. However, since the center angle of each engagement groove 26 is set to 45 °, the position of each engagement groove 26 remains the same as the initial state even after the rotation, and the engagement with the angular shaft 37 is established. Allow.
This relationship is maintained even when the memory button 19 is pressed by the operation tool 67 a plurality of times, because the rotation angle of the memory button 19 is set to an integral multiple of 45 °.
In other words, the storage button 19 is set in the transfer advance state by an angle corresponding to the password information than the lock cam 36.

Thereafter, the operation pin 66 is inserted into the operation hole 14 and the through hole 22 in the same manner as described above, the lock cam 36 is pushed and moved, and the operation tool 67 is further engaged with the button case 15 and pressed. 15 and the memory button 19, the lock cam 36 and the spring receiver 27 are pushed and moved back, and the memory button 19 and the spring receiver 27 are further rotated by 45 °.
Therefore, when the operation button 14 is pressed twice, the memory button 19 and the spring receiver 27 are rotated 90 ° from the initial reference position.

  Thus, the password information for the upper operation button 14 is set. This setting information is such that the rotation angle between the memory button 19 and the spring receiver 27 is maintained by the engagement of the dogs 18 and 20, and the angular axis 37. Is held by engaging the engaging groove 26 and preventing the memory button 19 from rotating.

Next, after setting the password information for the upper operation button 14, the password information for the lower operation button 14 is set. The setting operation is performed in the same manner as the upper operation button 14.
For example, if the password setting information of the lower operation button 14 is “3”, the operation button 14 is intermittently pressed three times via the operation tool 67, and the memory button 19 and the spring receiver 27 are rotated synchronously. Then, the password information “1” is set by adding three times.
When the password setting information is “0”, the operation button 14 is operated zero times as described above, that is, the state before the initial setting of the password information is set.
Further, also when the password information is set for the lower operation button 14, the spring receiver 27 is moved in association with the rotation of the memory button 19, the display board 31 is moved, and the display board 31 disappears from the display window 68.

In this way, the lower operation button 14 is intermittently pressed three times, and the memory button 19 and the spring receiver 27 are rotated 135 ° from the original reference position.
In the setting information, as in the case of the upper operation button 14, the rotation angle of the memory button 19 and the spring receiver 27 is maintained by the engagement of the dogs 18 and 20, and the angular shaft 37 is engaged. It is held by engaging the groove 26 and preventing the memory button 19 from rotating.

Note that, after setting the password information for the upper and lower operation buttons 14, 14, when confirming whether or not the input setting is correct, the operation handle 60 is rotated counterclockwise, the lock plate 43 is pushed down, and the locking claw 45 is moved. Is pulled out of the locking groove 39 of the lock cam 36.
That is, after the sliding door sickle lock 3 is set to the locking mode as shown in FIG. 4 and the lock cam 36 is rotatable, the operation button 14 is pressed as many times as necessary to display the display plate 31 on the display window 68. By the way, if the operation handle 60 can be rotated in the clockwise direction and the lock plate 43 can be pushed up, it is confirmed that the password information input setting is appropriate.

  That is, after the password information of the operation buttons 14 and 14 is set, the memory button 19 and the spring receiver 27 are set to rotate according to the password information, but their rotational positions are temporarily returned to the reference positions before the setting, When the locking groove 39 of the lock cam 36 is positioned in a vertically downward state and the locking claw 45 is inserted into the locking groove 39, it is confirmed that the lock plate 43 and the memory button 19 are functioning normally. It is confirmed that the PIN information setting is eligible.

  As described above, the setting operation of the password information for the operation buttons 14 and 14 can be performed by the pressing operation of the operation tool 67 having the operation pin 66. Therefore, the operation pin is inserted into the operation hole and kept pressed as in the conventional state. This eliminates the complexity of the two-handed operation of pressing the operation button while maintaining this, and can easily do this with one hand, and avoids the attachment of fingerprints to the operation button.

  After the password information of the operation button 14 is set in this way, when the sliding door inner lock 1 is actually closed and locked using the sliding door sickle lock 3, the inner door 1 is closed as shown in FIG. The grip portion 62 of 60 is positioned horizontally, and the drive cam 56 and the sickle 4 are interlocked with this to cause the sickle 4 to protrude, and the sickle 4 is latched to the opening edge 6 a of the toro receiver 6 in the door-to-door frame 5. .

  This state is as shown in FIGS. 1 and 4, and the lock plate 43 is pushed down by the elasticity of the spring 47 by the rotation of the operation handle 60, and the bent piece 46 is engaged with the long side portion 56 a of the drive cam 56. Then, the locking claw 45 is retracted from the locking groove 39 of the lock cam 36, and the lock cam 36 is placed in a rotatable state.

Further, the lock cam 36 is urged forward by the elasticity of the spring 52, one side engages with the stepped hole 35 of the partition plate 32, and the other side engages with the opening edge of the opening window 44 of the lock plate 43. They are close enough to prevent the locking cam 36 from moving in the axial direction.
Further, the angular shaft 37 of the lock cam 36 is engaged with the engagement groove 26 of the storage button 19 so that the lock cam 36 and the storage button 19 can be rotated synchronously.

Thereafter, the user presses the upper and lower operation buttons 14 and 14 with his / her fingers as many times as necessary, that is, adds the camouflage information arbitrarily to the password information so that the password setting information is not detected, and normally uses the operation buttons 14 and 14 Set to state.
That is, the button case 15 and the memory button 19 are pushed in against the elasticity of the spring 29, and these are pushed back to the original position by the elasticity of the spring 29.
At that time, the cam 23 of the storage button 19 is engaged with the taper portion of the guide rib 13, the storage button 19 is helically rotated, and the spring receiver 27 fitted to the rectangular shaft tube portion 24 is synchronously rotated. Move.

Then, the memory button 19 and the square shaft 37 or the lock cam 36 engaged with the engagement groove 26 in the square shaft cylindrical portion 24 are synchronously rotated, and the locking groove 39 is changed from the vertically downward direction to an arbitrary position. The peripheral surface of the protruding shaft 38 and the locking claw 45 are positioned so as to be engageable.
As described above, in the normal use state of the operation button 14, the operation button 14 is pressed by the camouflage information, and the memory button 19, the spring receiver 27, and the lock cam 36 are set by increasing the rotation angle by the camouflage information.

As described above, when the sliding door sickle lock 3 is locked, the lock cam 36 is prevented from moving in the axial direction. Therefore, the lock cam 36 is moved by inserting the operation tool 67 or a similar unauthorized tool into the operation hole 16 at the time of locking. It can prevent unauthorized operations and mischief.
Further, since the engaging claw 45 of the lock plate 43 and the peripheral surface of the projecting shaft 38 of the lock cam 36 are positioned so as to be engageable with each other, the vertical movement of the lock plate 43 is restricted, and the drive cam 56 or the operation handle 60 is operated. The rotation of the sickle 4 becomes impossible, and the hooked state of the sickle 4 is maintained.

In this situation, when unlocking the sliding door sickle lock 3 and opening the inner door 1, first, the two operation buttons 14 and 14 are pressed with fingers for the required number of times and displayed on the display windows 68 and 68. The plates 31 and 31 are displayed, respectively, and the sliding door sickle lock 3 is once set to the password information setting reference position.
That is, the operation button 14 is pressed a required number of times, the storage button 19 and the spring receiver 27 are rotated synchronously, and the display board 31 is positioned on the display window 68 of the lock case 7. In this case, the angular shaft 37 or the lock cam 36 also rotates synchronously, but does not affect other members only by idling.

When setting the reference information setting reference position, if the reference position of the memory button 19 or the spring receiver 27 is set to the rotation angle 0 ° or 360 ° position, the password information and the password information are set from 0 ° or 360 °. The difference of the addition amount of each rotation angle with the camouflage information, the memory button 19 etc. are rotated for the reference position setting, and the set angle and the angle for the camouflage information are common. The phase is delayed from the reference position by the password information angle.
Therefore, when the reference position is set, the locking groove 39 of the lock cam 36 is not placed in the vertically downward state.

Therefore, the upper and lower operation buttons 14 are pressed by a finger a predetermined number of times based on the respective password setting information.
That is, the upper operation button 14 is intermittently pressed twice based on the password setting information “2”, and the lower operation button 14 is pressed intermittently three times based on the password setting information “3”.
In this way, the memory button 19 and the spring receiver 27 move together, and the square shaft 37 or the lock cam 36 that engages with the engagement groove 26 of the square shaft cylindrical portion 24 rotates in synchronization therewith. The groove 39 is positioned vertically downward and faces the locking claw 45 directly below.

Therefore, the holding part 62 of the operation handle 60 is held, and this is rotated 90 ° clockwise in FIG.
In this way, the drive cam 56 rotates in synchronization with the operation handle 60, and its short side 56 b engages with the bent piece 46 of the lock plate 43, so that the lock plate 43 becomes elastic to the spring 47. The locking claw 45 engages with the locking groove 39 of the lock cam 36.

For this reason, the rotation of the lock cam 36 is blocked, the rotation of each operation button 14 is blocked, and the unauthorized operation or mischief of the operation button 14 at the time of unlocking is prevented. Is housed in the lock case 7 and the latching with the mouth edge 6a of the toro receiver 6 is released.
Therefore, after that, if the handle (not shown) of the inner door 1 or the operation handle 60 is gripped and moved, the inner door 1 can be opened.

  On the other hand, when the sliding door sickle lock 3 is locked after the inner door 1 is opened, the inner door 1 is closed, and the operation handle 60 is turned 90 ° counterclockwise from the unlocked state, and the drive cam 56 is moved to cause the sickle 4 to protrude from the sliding sickle lock 3, and is hooked on the mouth edge 6 a of the toro receiver 6.

As the operation handle 60 is locked, the lock plate 43 is pushed down by the elasticity of the spring 47, and the bent piece 46 engages with the long side portion 56 a of the drive cam 56.
Thereafter, the upper and lower two operation buttons 14 and 14 are pressed with a finger as many times as necessary, and the camouflage information is added to the password setting information to set the normal use state.
That is, the operation buttons 14 and 14 are pressed with a finger as many times as necessary, and the lock cam 36 is rotated by an appropriate angle so that the engagement claw 45 and the peripheral surface of the protruding shaft 38 can be engaged, thereby preventing the lock cam 36 from moving in the axial direction. Thus, the personal identification number of the operation buttons 14 and 14 is prevented from being falsified or illegally operated.

It is desirable for security reasons to periodically change the password information of the operation buttons 14, 14. In this case, the operation pin 66 is inserted into the operation hole 16 and the through hole 22, and the engagement groove 26 of the memory button 14 is The engagement with the angular shaft 37 of the lock cam 36 is released.
Specifically, the password information may be changed depending on whether the password information, for example, the password number is increased or decreased, and the changing operation is different.
For example, the personal identification number of the lower operation button 14 is “3”, but when this is changed to “4”, an increase in the personal identification number, that is, a press operation is performed once while the operation pin 66 is inserted. good

  On the other hand, when the password of the lower operation button 14 is changed to “2”, the operation button 14 is kept pressed while the operation pin 66 is inserted, and the display board 31 is displayed on the display window 68 to temporarily return to the initial state. After returning, the operation button 14 may be newly pressed corresponding to the change, that is, pressed twice.
