For example, a set block is attached to the surface of the case frame of the mechanical lock lock, a plurality of plates are laminated inside the case frame, and a plurality of slits or through holes are formed in the plate, A substantially S-shaped plate-like button having a notch groove is inserted into the slit or through-hole in an upright or inverted state, and the push button is set in a memory state or a non-memory state, and a password is input. There are some (see, for example, Patent Documents 1 and 2).

However, when setting or changing the security code, the mechanical lock lock removes the set block and case frame from the door to reveal the button, and disassembles adjacent parts to recombine the upright or inverted state of each button. In addition, it takes a troublesome work to insert this into the slit, and it takes time and effort, and there is a problem that the upright or inverted state of the button is very similar and easy to make mistakes. Or, if you operate the push button with an incorrect PIN number and then try to open the door by operating the lever handle, the pinion integrated with the lever handle and the rack gear meshing with the pinion will be damaged, and the cam pin will be the keypad. -There was a problem that it was bent due to contact with the tongue and became unusable.

  On the other hand, a plurality of plates are laminated inside the case frame in another mechanical lock, and a plurality of slit notches or slide notches are formed on the plate, and a plurality of stopper flanges are projected on these plates. Insert the pin-shaped button body installed, place the stopper flange so that it can be engaged with the protrusion of the slide notch of the adjacent plate, set the button body to the memory state or non-memory state, and enter the PIN (For example, refer to Patent Document 3).

However, the button main body has a complicated shape, is difficult to process, and has a problem of high manufacturing costs.
In addition, if the push button is pressed incorrectly or the button body is operated with the wrong password, then the lever handle is operated to open the door, causing the rotating cam to abruptly contact the key plate and damage both. Or the two stopper flanges engage with the protrusions of the slide notches of the key plate and button press plate, and both stopper flanges and slide notches are damaged or broken, making them unusable. There was a problem of becoming.
Such a problem may be caused by a third party or a trespasser who does not know the personal identification number in addition to the user who knows the personal identification number, and has been desired to be improved in terms of structure and crime prevention.

Thus, the button lock can be used after adjusting the mounting angle of the lever handles 5 and 6.

In the use of a button lock, after the password information is set, when the door 1 is closed, the automatic lock functions, and the dead bolt 8 is engaged with the door frame side trolley (not shown) and locked.
At the time of locking, the eight lock pins 19 corresponding to “12348ABC” set with the personal identification information are placed in the state shown on the left side of FIG. 38, and the inner peripheral portion of the engagement groove 24 is a dog 58 of the lock hole 57. The lock plate 56 is positioned so as to be engageable immediately above, and the lock plate 56 is prevented from moving upward to form a locked state.

  Therefore, the pressing operation of the enter button 13 which is the subsequent unlocking start operation becomes impossible, and the locked state is maintained. In this case, the greater the number of password information setting amounts or the number of lock pins 19 that are substantially unlocked / locked, the more firmly the blocking plate 56 can be prevented from moving upward.

  Under such a locked state, when a third party who does not know the set personal identification information presses the enter button 13 from the outdoor side by mischief or illegal operation, the enter button 13 is moved to the enter button spring 85. The double torsion spring 79 attached to the flange portion 73 of the button 13 is moved to the inside of the outdoor seat 3 against this, and the spring engagement end 81 thereof is a bent piece 36 of the probe preventing plate 34. And the search preventing plate 34 is pushed up against the elasticity of the spring 39.

  The probing prevention plate 34 is normally pushed down by the spring 39, the bent piece 36 engages with the spring engaging end 81, and the lock pin 19 penetrates an intermediate portion of the engaging groove 40 of the probing prevention plate 34. Are arranged. This situation is as shown in FIG.

When the probing prevention plate 34 is pushed up under this condition, the edge of the engagement groove 40 is strongly engaged with the lower surface of the lock pin 19 and slightly pushes up the intermediate portion of the lock pin 19.
This situation is as shown in FIG. 16, in which the behavior of the lock pin 19 or the push button 12 is restricted or prevented, making it impossible to detect the presence or absence of password information setting input by the lock pin 19 or the push button 12, and obtaining a high defense capability. It is done. Therefore, unlocking by illegal intruders and third party mischief can be prevented.

Next, when unlocking such a locked state, the eight push buttons 12 corresponding to “12348ABC” set with the password information are pressed in an appropriate order from the outside of the outdoor seat 3.
The unlocking procedure is as shown in FIG. 41, and this will be explained with the push button 12 of the alphabet character display arranged in the center of the outdoor seat 3. Before the pressing operation of the push button 12, it is as shown in step 1 of FIG. This is the same as shown on the left side of FIG.
That is, at the time of locking, the push button 12 protrudes to the outside, the lock pin spring receiver 16 is engaged with the lock pin 19 while holding the lock pin 19, and the rear end portion of the lock pin 19 can be engaged directly above the lock plate 56. The end of the reset spring 52 is engaged with the base of the one-side taper surface 22a.

  Therefore, when the locked push button 12 is pressed, the push button 12 and the lock pin 19 are pushed against the elasticity of the push button spring 33 and the lock pin spring 32, and the end of the reset spring 52 is the taper surface 22a. The end of the reset spring 52 moves to the side of the through hole 45 and moves to the spring hooking groove 50 formed in the reset plate base 42. This situation is like steps 2 and 3 in FIG.

The front end is engaged with the bent piece 62 at the lower end of the lock plate 56, and the lock plate 56 that can be moved upward as described above is pushed up against the set spring 59. This situation is as shown in FIGS. 14 and 16. In this way, the upper end of the pivot plate 65 rubs through the lower end of the bent piece 62 and moves from one side of the bent piece 62 to the other side. At this time, since the tongue piece 65a of the pivot plate 65 is formed on the convex curved surface, the engagement with the bent piece 62 can be performed smoothly.

The engagement between the distal end portion of the pivot plate 65 and the bent piece 62 is maintained until the lever handle 5 described later is rotated, during which the lock plate 56 is pushed up and the tilt displacement of the clutch shifter 64 is increased. Is maintained.
Then, when the enter button 13 is released after the pressing operation, the enter button 13 is pushed back to the original position by the elasticity of the enter button spring 85, and the double torsion spring 79 is moved to this position so that the search prevention plate 34 is moved. Pushed back.

Thus, when the clutch shifter 64 is pivoted about the pivot projection 70 and the lower half of the clutch shifter 64 is inclined and displaced outward, the projection 73 formed on the pair of shifter plates 71 engages with the recess 75 of the shift gear 74. The shift gear 74 is pressed to the outdoor side, and the outer portion of the projection 73 is engaged with the recess 103 of the clutch gear outer 96.
Therefore, the shift gear 74 moves to the outdoor side against the elasticity of the set spring 98, the inner gear 93 on the small diameter side of the shift gear 74 meshes with the gear 92 of the clutch gear inner 72, and the large diameter side of the shift gear 74 The inner gear 95 meshes with the annular gear 97 of the clutch gear outer 96.

  When the gears 74, 92, 93, 95, 97 are engaged, the rotational power of the clutch gear outer 96 can be transmitted to the shift gear 74 via the gears 92, 90, and the rotational power of the shift gear 74 is transmitted to the gear 97. 95, the clutch gear inner 72 can be transmitted to the clutch gear inner 72, and the rotational power of the clutch gear inner 72 can be transmitted to the square core rod 87.

Thereafter, when the lever handle 5 on the outdoor side is rotated, the turning force is transmitted to the clutch gear outer 96 via the handle joint 115, and the turning force of the gear outer 96 is sent to the clutch gear inner via the shift gear 74. -72.
Then, the turning force of the clutch gear inner 72 is transmitted to the square core rod 87, and the turning force of the square core rod 87 is transmitted to the rotating cam (not shown) of the main locking 7, and the dead bolt 8 is The door 1 can be opened by being pulled out from the trolley (not shown).

  As the lever handle 5 is rotated, the clutch gear outer 96 is rotated through the handle joint 115, and the lower end is engaged with the engagement surface 105 of the clutch gear outer 96 as described above. The reset plate 41 is pushed up integrally, and the reset spring 52 attached in the interior thereof is separated from the lock pin 19. This situation is as shown in FIGS. 11 (a) and 11 (b).

  For this reason, the engagement between the reset spring 52 and the engagement recess 23 is released, and the lock pin 19 is pushed up by the elasticity of the lock pin spring 32, that is, moves outward, and the tip thereof is the same as the lock pin spring receiver 16. It moves and engages with the inner surface of the push button 12, and the engagement protrusion 22 engages with the engagement groove 40 to form the initial locked state. This situation is like step 1 in FIG.

When the clutch gear outer 96 and the shift gear 74 are rotated through the handle joint 115 as the lever handle 5 is rotated, the recesses 103 and 75 formed on the end surfaces thereof are rotated. The engagement between these and the protrusion 73 of the shifter plate 71 is released.
For this reason, the shift gear 74 is pushed back by the elasticity of the set spring 98, the shifter plate 71 is moved back to the original position, and the upper portion thereof is displaced outward with the pivot projection 70 as a fulcrum, and is pivotally attached. The upper end of the plate 65 releases the engagement with the bent piece 62 and returns to the original position.
This situation is as shown in FIG. 13, and the clutch operation of the clutch mechanism 63 stops.

Thereafter, when the lever handle 5 is released, the clutch gear outer 96 is returned and rotated by the elasticity of the lever lock plate 111 and the spring 113, the reset plate 41 is moved downward, and the reset spring 52 is moved to the lock pin 19. It approaches and engages the base of the tapered surface 22a.
