[0009]

The operation of the invention of claim 1 will be described.
In this lock handle device for a door with a built-in lock, a large number of persons who are permitted to use the device by the owner or manager of the device are assigned an unlocking code string for themselves by the owner or the manager in advance. . One of the many is
When opening the door to use the device, a plurality of dial discs are arranged so that the code sequence consisting of the permutation sequence of the codes attached to the outer peripheral surfaces of the dial discs becomes the unlocking code sequence assigned to the user. Rotate the dial disk normally and reversely.

As shown in FIG. 4, when the codes of the respective dial disks 4 are arranged in the assigned unlock code string, the code matching lock 6 is in the unlocked state. In this unlocked state,
As shown in FIGS. 14 and 15, the lock end portion 25 of the lock plate 5 is at a level position where it cannot engage with the stopper portion 26 of the slider 21, and the slider moves toward the main portion of the code matching lock 6. The backward movement of 21 is unblocked. Further, at this time, the cylinder lock 13 is in a locked state, and the tip portion 14 of the stopper plate 11 has the receiving lever 1
6 is engaged with the step portion 15, and this engagement state is maintained by the rotational biasing of the spring member 19. for that reason,
The handle 2 is constrained to a fall position, which is housed in the front recess 27 of the base body 1.

In this state, when the handle 2 is pulled out from the base body 1 about the pivot 28 of the base end and rotated, as shown in FIG. 5, the tip 14 of the stopper plate 11 is rotated.
Is an inclined cam surface 1 continuous with the step 15 of the receiving lever 16.
In order to push 8, the receiving lever 16 retracts and rotates in the restraint releasing direction about the pivot 17, and the receiving lever 16 pushes the tip portion 23 of the slider 21 to move the slider 21 backward as shown in FIG. The handle 2 is the base body 1
At the stage where it is pulled out to a certain angle from
Since the tip end 14 does not press the receiving lever 16 again, the receiving lever 16 is returned to the substantially horizontal standby position as shown in FIG. 7 by the bias of the spring member 19. Also,
The slider 21 is also returned to its original position by the bias of the spring member 22.

Can be pulled out and rotated. The senior authority is given the key 7 of the cylinder lock 13. none '>
As shown in FIG. 10, when the dial disk 4 is turned to an irregular angle by an outsider or an intruder who does not know the predetermined unlock code string, and the code matching lock 6 is unintentionally set to the locked state. , The senior administrator can reset the locked state.

As a preparation step for the reset operation, the senior authority inserts the key 7 into the key hole 9 of the rotor 8 of the cylinder lock 13, and drives the internal lock mechanism 10 in the releasing direction by the required key crest code. When the rotor 8 made rotatable by this is rotated in the unlocking direction by the key 7, the stopper plate 1
1 is pulled into the inside of the handle from the side surface through hole 12 of the handle 2, and the engagement state between the tip portion 14 of the stopper plate 11 and the step portion 15 of the receiving lever 16 is released.

As described above, when the code-matching lock 6 is in the locked state, the locking end portion 25 of the lock plate 5 comes to the position where the stopper portion 26 of the slider 21 abuts, and therefore the backward movement of the slider 21 causes the lock plate 5 to move backward. Therefore, the receiving lever 16 cannot be retracted and rotated in the restraint releasing direction. However, when the cylinder lock 13 and unlocked operated with a key 7, since the catch plate 11 is submerged retreat to a position not exposed to the socket member the lever 16, FIG. 1
1 and FIG. 12 , the handle 2 is the receiving lever 16
Is pulled out from the front concave portion 27 of the base body 1 without being interfered with. After opening the door 30, by operating an appropriate resetting device from the back side of the door 30, the irregular locked state is released and the recovery process is performed.

When the user forgets the unlocking code string of the code-matching lock 6 and cannot use the code-matching lock 6, it is preferable that a senior authority who is given a broader management authority than a general user. As shown in FIGS. 26 and 27, the reset member 72 is inserted into the code lock 6 from the opening 75 of the handle 2 in a predetermined insertion direction and insertion depth (step (1) in each figure). ), The tip of the reset member 72 is attached to the peripheral surface of the cam disk 41 (step (2) in each figure). While keeping the insertion position of the reset member 72 constant, the dial disc 4 is rotated to engage the tip end portion of the reset member 72 with the detection groove 71 of the cam disc 41 (step (3) in each figure). The code displayed at the normal position of the code display portion of the handle 2 when the reset member 72 and the detection groove 71 are engaged is stored or recorded as the code set for unlocking.

By repeating this operation procedure for all dial disks 4, the code set for unlocking each dial disk 4 is detected and confirmed. these
By arranging the confirmed unlocking codes in order, the unlocking code string initially set for the code matching lock 6 can be obtained. The senior authority notifies the general user of the original unlocking code string confirmed in this way, and the user appropriately rotates each dial disc 4 forward and backward according to the unlocking code string. The code-matching lock 6 can be reused.
