Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lock used for a bag such as a trunk.
[0002]
[Conventional technology and problems]
Conventional locks are designed to rotate by inserting a key into the keyhole, but it is difficult to twist the wrist and the structure of the part around the tumbler is complicated. Moreover, since the structure is known for a conventional rotary key, there is a risk of encountering theft such as picking.
[0003]
[Means for Solving the Problems]
In order to eliminate the above-mentioned drawbacks, the present invention inserts a key from the key hole of the key slide and moves it laterally in a lock having a key slide provided with a locking portion that engages with the base of the lock. Thus, by disengaging the tumbler in the key slide from the inner plate pivotally attached to the slider, the key slide is moved to disengage the lock portion of the key slide from the lock base. It is a lock obtained by being configured so that it can be used.

5 is a front view of the lock 50, and FIG. 6 is a cross-sectional view taken along line AA of FIG. The lock shown in FIG. 5 and subsequent figures is for the lock 50R on the right side of FIG. 1. However, since the structure is the same except that the directions of 50R and 50L are different, only 50R will be described unless otherwise specified. .
[0008]
7 and 8 are views showing the structure around the tumbler when FIG. 6 is viewed from the direction D, and FIG. 9 is a cross-sectional view showing the locked state of the lock of the present invention.
[0009]
The structure of the lock 50 of the present invention will be described with reference to FIGS. 4 to 9. The key slider cover 4, the click plate 9, the seal 15, and the key slide 3 are attached to the cover 7. Further, the inner plate 8 is attached to the cover 7 together with the latch 5 with rivets 18. A cover assembly 70 in which the inner plate 8 and the like are attached to these covers 7 is pivotally supported on the slider 2 in the base 6 by rivets 12B. Further, one end of the link 16 is pivotally supported on the base 6 by the side lock shaft 19, and the other end is pivotally supported on the inner plate 8 by the rivet 12A.
[0010]
The latch 5 is urged by a latch spring 14, and the latching portion 43 of the latch and the latching portion 44 formed on the base 6 are engaged when locked as shown in FIG. 9. At the same time, the locking portion 41 of the key slide 3 is engaged with the locking portion 42 formed on the base 6.
[0011]
Further, when the slider 2 is locked, the slider 2 is at the left end of the base 6 as shown in FIG. 9, and the key hook passage hole 65 of the base 6 and the key hook locking hole 25 of the slider 2 are overlapped. The key hook 21 is attached to the side wall of the bag, and a locking portion 45 at the tip thereof enters the lock from the key hook passage hole 65 of the base 6 and engages with the key hook locking hole 25 of the slider 2.
[0012]
As shown in FIGS. 6 and 7, at the time of locking, the sliding tumblers 10 and 11 are pushed by the tumbler spring 20 into the hole of the inner plate 8, and the key slide 3 incorporating the tumbler cannot move. The whole is in the locked state shown in FIG.
[0013]
When opening the bag, the key is inserted from the key hole 51 in the key slide cover 4 above the key slide 3, the tumblers 10 and 11 are moved against the tumbler spring 20, and the tumbler is removed from the hole of the inner plate 8. Since the state of FIG. 8 is reached and the key slide 3 can be moved, if the key slide 3 is moved to the left in FIG. 9 as it is, the state of FIG. 10 is obtained and the engagement between the locking portion 41 of the key slide 3 and the base 6 is established. The engagement with the stopper 42 is released, and the key is released as shown in FIG.
[0014]
Then, the latch 5 is turned counterclockwise (P direction in FIG. 11) against the latch spring 14 to disengage the latch locking portion 43 and the locking portion 44 of the base 6, and the cover 7 is moved slightly upward. Lift up so that the position of the rivet 12 </ b> A is slightly above the position of the side lock shaft 19. Since the slider 2 is urged to the right in the drawing by the slider spring 17, the locking portions 41 and 43 are disengaged, and the rivet 12A is slightly above the side lock shaft 19, so that the slider 2 is shown in FIG. As shown in FIG. 4, the cover assembly 70 is moved rightward while jumping upward.
[0015]
Then, the key hook locking hole 25 also moves to the right and is disengaged from the locking portion 45 of the key hook 21 to enter the open state shown in FIG. 12, and the bag lid can be opened.
[0016]
In the illustrated example, the lock hook 21 is fixed to a bag lid 31, and the locks 50 (R, L) are attached to the front side wall 34 of the storage portion 32. The click plate 9 produces a click sound at both ends of the movement of the key slide 3 to give a sense of response, and has an effect that the key 1 cannot be removed during the movement of the key slide 3.
[0017]
When closing the bags, the cover assembly 70 is rotated clockwise from the open state in FIG. 12 to the key open state in FIG. (The latch 5 is automatically engaged by the latch spring 14.) The key 1 is inserted into the key hole 51, the tumblers 10 and 11 are removed from the inner plate 8 as shown in FIG. 8, and the key slide 3 is moved to the right. 9 to the locked state shown in FIG.
[0018]
【The invention's effect】
The lock according to the present invention is configured as described above, and is operated by moving the key in the lateral direction instead of rotating. Therefore, the operation and the structure around the tumbler are facilitated, and the lock is advantageous for antitheft measures such as picking. Could get.
