[Embodiment] Fig. 1 is an exploded perspective view showing an embodiment of the lock according to the present invention. We are prepared.

Reference numeral 5 denotes a cover fixed to the base body 1, and is provided with a space 6 opened at both ends in the longitudinal direction and in a direction facing the base body 1 for accommodating other parts. The part facing the key hole 2 and the part facing the keyhole 2 are closed by the base body 1.

Reference numeral 7 denotes a fixed body fixed to the base 1 within the space 6 of the cover 5, and 8 is a movable body movable in the horizontal direction in contact with the fixed body 7.

A pin tumbler lock is formed by the fixed body 7 and the movable body 8, but when compared with the parts of a general cylindrical pin tumbler lock, the fixed body 7 is considered to be an outer cylinder, and the movable body 8 is considered to be an inner cylinder. be able to.

The facing portions of the fixed body 7 and the movable body 8 are in contact with each other, and the contact surface 9 corresponds to the shear line between the inner and outer cylinders of a general pin tumbler lock.

10 is a movable body 8 inside the cover 5.
A locking body rotatably attached to the end of a shaft 11,
It is always urged to rotate in the locking direction under the action of the spring 12.

The locking body 10 has a pressed end 1 facing the movable body 8.
3, and the pressed end 13 is accommodated in the first recess 2 of the base body 1 when locked.

Furthermore, the locking body 10 has an engaging end 14 facing the unclosed opening of the space 6 of the cover 5;
When locking, this engaging end 14 engages with a locked piece 15 connected to a bag closure (not shown) inserted into the cover 5 through the opening, so that the locked piece 15 is integrated with the cover 5. Fix it.

In the cross section of the pin tumbler lock of the bag lock of the present invention shown in FIG. It is.

A spring 17 and a driver 18 are accommodated in the fixed body 7 portion of the pin hole 16, and a pin hole 16 in the movable body 8 portion that opens into a keyway 19 drilled in the movable body 8.
A pin 20 is housed therein.

Furthermore, an intermediate body 21 having a smaller diameter than these is interposed between the driver 18 and the pin 20.

As shown in FIG. 7, when the pin holes 16 of the fixed body 7 and the movable body 8 are aligned in the locked position, the end of the driver 18 enters the pin hole 16 on the movable body 8 side. Since the driver 18 is crossing the contact surface 9, the movable body 8 is integrated with the fixed body 7, and the locked state is maintained.

Reference numeral 22 denotes a housing recess bored in the contact surface 9 of the movable body 8 adjacent to the pin hole 16, and when the movable body 8 moves to the unlocked position, the fixed position that coincides with the locked position is removed. It is bored so as to be located directly below the pin hole 16 on the body 7 side.

The diameter of the receiving recess 22 is smaller than the diameter of the driver 18, but is large enough to accommodate the intermediate body 21.

The key 23 shown in FIG. 2 is suitable for use in the bag lock of the present invention, and is inserted into the keyway 19 of the movable body 8 to press the pin 20 toward the fixed body 7. , its cross section is approximately rectangular, and a recess 24 corresponding to the required movement amount of the pin 20 within the pin hole 16 is bored in the surface facing the pin hole 16 .

For reference, the types of depths of the recesses 24 in this embodiment will be explained. When the thickness of the key 23 is 2.5 mm, it is possible to set four levels of depth at a pitch of 0.5 mm. .

To lock the bag, the bag lock of the present invention constructed as described above is installed on a bag, etc., and the locking piece 15 connected to a closure member (not shown) such as a zipper is secured to the cover as shown in FIG. Insert it inside through opening 5.

As a result, the tip of the locking piece 15 rotates the locking body 10 around the shaft 11 against the action of the spring 12, and once pushes down the engaging end 14, the locking piece 1
5 is further pushed deeper into the cover 5, the engaging end 1 of the locking body 10 returns to its original state due to the action of the spring 12.
4 captures the locked piece 15, and locking is completed as shown in FIG.

To unlock the lock, from the state shown in FIG. 7, the key 23 is inserted into the keyway 19 of the movable body 8 through the keyhole 2 of the cover 5, and the pin 20 is raised by the required amount.

As the pin 20 rises, the end of the driver 18 is moved to match the contact surface 9 between the fixed body 7 and the movable body 8, as shown in FIG. is released, and the movable body 8 can be moved inside the cover 5 as shown in FIG.

The internal state of the pin tumbler lock portion in this case is as shown in the sectional view shown in FIG.

When the movable body 8 moves, the locking body 10 pivoted to the movable body 8 also moves, whereby the first recess 3 of the base body 1 presses the pressed end 13 of the locking body 10, and the lock is locked. Since the body 10 is rotated about the shaft 11 to the unlocked position against the action of the spring 12, the engagement between the engaging end 14 of the locking body 10 and the locked piece 15 is released, and the locked piece 15 The closure body (not shown) integrated with the can now be moved freely.

Next, to replace the key 23, insert a new key 23a prepared in advance into the key groove 19 as shown in FIG. Only one person will be able to operate this lock.

[0028] In the new key 23a prepared in advance for key exchange, only one of the plurality of recesses 24 installed in the key 23a is drilled shallower than the recess of the previously used key 23. .

If this shallowness is, for example, 1.0 mm and the diameter of the intermediate body 21 is 1.0 mm, then the new key 23
If a is inserted, only the pin 20 at the recess 24 will move by 1.0 mm.

At the location of the pin 20, the intermediate body 21
is pushed up into the fixed body 7, and the boundary between the intermediate body 21 and the pin 20 coincides with the contact surface 9 between the fixed body 7 and the movable body 8, as shown in FIG.
The movable body 8 becomes movable as shown in FIG.

When the movable body 8 moves to the position where unlocking is completed as shown in FIG. 11, the intermediate body 2 that was inside the fixed body 7
1 is moved and dropped into the accommodation recess 22 by the action of the spring 17.

Once the intermediate body 21 has moved and fallen into the storage recess 22, this pin 20 must be removed during subsequent unlocking operations.
As for the part shown in FIG. 1, the boundary between the pin 20 and the driver 18 coincides with the contact surface 9 to unlock the door, so that only the new key 23a can be used for unlocking.

By providing the same number of accommodating recesses 22 as the pin holes 16, it is possible in principle to exchange keys the same number of times as the number of pin accommodating recesses 22.
