, 7m, and each of the selected tumblers 7, 7 is locked in a position where the end edge thereof is aligned with the first shear line. As a result, as shown in the third factor, the end edge of 111Il becomes the engagement protrusion 14 a of the cons bar.
The four tumblers 7, 7 in the central part of the inner cylinder facing each other become inoperative.

Therefore, as shown in Fig. 6, the part facing the group of tumblers locked to the cons bar 14 is cut out and made thinner, and the part corresponding to the tumblers in the operating state is formed with a regular keyway. When the key CK is inserted into the keyhole, the edges of the two activated tumblers 7, 7 (see Figure 3) align with the first shear line, and the inner cylinder 3 becomes rotatable. Become. That is, when the construction key device is activated, the cons tumbler actually becomes an unlocked mark.

At this time, as shown in FIG. Master pin 2],

Since the cons bar 14 and the release grating 16 rotate integrally with each other, the relative positions of the cons bar 14 and the release grating 16 do not change, and the operating state of the construction key device is maintained.

10,000, the set IK handed to the tenant after the construction is completed, as shown in Figure 7, is the part that corresponds to the tumblers 7, 7 that are locked to the Consno Z-14 when the construction key device is activated. At the same time, the vertical hole 5 is formed.
The difference between the thickness of the cons ring 17 and the radial dimension of the long cylinder 3 of the master pin 21 is the deep notch r4. '15 and 25 are formed.

Therefore, when this combination is inserted into the keyhole, it is natural that the edges of all the tumblers of the cons tumbler lock will align with the first shear line 1C, resulting in a failure state. As shown in the eighth row, the valley bottom pin 19 engages in the notch groove δ due to the elasticity of the control pin spring, and as a result, the inner end surface of the master pin 21 aligns with the third shear line, and the FA top pin /4 now straddles the second sheer line.

In this state, if you turn the NIK'2 No. 8 counterclockwise,
This time, the top pin 22, z: The inner cylinder 3 rotates relative to the cons ring 17 which is locked to the outer cylinder 1, and the release sill 1-16 and the release groove 17 are rotated.
At the angular position H where the cons bar 14s and the release plate 16 are aligned, the cons bar 14s and the release grating [6] move outward due to the elasticity of the cons bar spring 150, and the release plate 16 engages in the release groove 17m. As a result, the second evil and the fourth
As is clear from the figure, the locking of the selected tumblers by the cons bar 14 is released and these tumblers return to the operating state, but since each tumbler is engaged with the keyway of the duplicate key IK, , all tumbler edges remain aligned with the first shear line 1.

When the duplicate key IK is rotated further, the cylinder 3 is left in the IJ Lease Grate 16 release 817a and rotated, and after operating the deadbolt, when the duplicate key IK is returned clockwise as shown in Figure 8,
On the return trip, release grade 16 and consuba-1
4 and 4 are only in sliding contact with each other.

When the duplicate key IKi is returned to the angular position where it can be pulled out, the state shown in FIG. 8 is reached.

C'), the cons tumbler lock according to the present invention releases the construction key gm by the owner's or tenant's first unlocking operation using a duplicate key. ! 6e, and the construction key device will not be activated by the subsequent j% scale failure. In other words, the release play 1-16 does not interfere with the old cons bar I$13.

After removing the construction key, the cons tumbler sputum according to the present invention functions as a normal tumbler charcoal.

Also, during construction, tl 7. : It goes without saying that N4 brewing using the construction key CK is Komachi-ized.

〔effect〕

As is clear from the above explanation, the invention is such that the construction key device is unlocked by the first unlocking operation by the combination a, so knowledge of the structure of the lock and special tools as mentioned above are not required. This greatly streamlines the work to release the construction key device.

Also, for the same reason, the number of people handling the lock can be minimized, and the safety of the lock can be further improved.

Furthermore, the shape of the construction key can be made completely different from that of the replacement key, so there is no risk of it being duplicated from the construction key, among other effects. play.

[Other Examples]

What? , the invention'! The implementation is not limited to the illustrated embodiment, and can be implemented with various modifications.

For example, in the illustrated embodiment, the entire width of the key blank is provided at the side edge of the construction that contacts the bottom pin when inserted into the hole.
This is not necessarily an essential component of the invention, but a shallow groove χ is formed here and the bottom pin has a long comb.
10, the notch of the duplicate key may be made deeper than the above shallow groove by the difference between the thickness of the consling and the length of the master pin (
(not shown). This has the advantage that the control pin group consisting of the bottom pin, master pin and top pin functions in the same way as a tumbler pin in a so-called pin tumbler, increasing the misalignment of the tumbler lock.
