Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a side lock of a bag lock having a center lock and a side lock.
[0002]
[Prior art]
A large bag such as a travel bag usually has a center lock and a side lock. The center lock is unlocked, and a push lever of the side lock is pushed to release the side lock. Also, if the center lock is locked, the push lever is prevented from moving, and it does not move when the push lever is pressed, and the bag cannot be opened.
[0003]
[Problems to be solved]
In the conventional structure described above, even if the center lock is locked to prevent the side lock push lever from moving, if the push lever is struck with a strong force, the impact is transmitted to the center lock, and the lock is broken. There was a fear. Therefore, it is necessary to prevent the impact from being transmitted to the center lock even if the push lever is hit with a strong force while the center lock is locked.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a side lock of a bag lock having a center lock and a side lock, wherein the push lever is divided into a push lever pressing piece and a push lever collar, and these two portions are pushed. The side lock of the bag lock characterized by combining through the spring stronger than the spring which supports the lever itself is obtained.
[0005]
【Example】
FIG. 1 is a front view of a typical example of a travel bag having a center lock and a side lock. A bag 10 includes a bag body 1, a lid 2, a front handle 3, a caster 4 for movement, and a handle 5 on a side. have. A dial lock 20 is provided as a center lock. Reference numeral 21 denotes a dial (four in the illustrated example), 30 denotes a side lock, and 31 denotes a push lever. A window 6 indicates whether the center lock is locked or unlocked.
[0006]
2 is a top view showing the arrangement of mechanisms of the dial lock 20 as the center lock and the right side lock 30, and FIG. 3 is a view showing the same as seen from the front. In other words, FIG. 2 corresponds to a view of FIG. 3 viewed from the Y direction, and FIG. 3 corresponds to a view of FIG. 2 viewed from the X direction.
[0007]
Although the right side lock will be described below, the configuration and operation of the opposite side lock are the same.
[0008]
In the side lock 30, the push lever 31 at the right end is divided into two parts, a push lever pressing piece 32 and a push lever flange 33, and they are combined as shown in the figure via a first spring 34. The push lever 31 is in contact with the first push plate 35, and the first push plate is connected to the second push plate 36 at the connecting portion 38. Further, the second push plate 36 is normally biased to the right side (the push lever 31 side) by a spring 37 between the second push plate 36 and a spring column 41 provided on the bottom plate 40. The push plates 35 and 36 are prevented from moving to the left side or become free by the action of the dial lock 20 described later.
[0009]
Further, the push lever 31 is urged rightward by a second spring 48 having a fulcrum on the bottom plate 40. In the present invention, the push lever 31 is divided into two parts, and the first spring 34 is considerably stronger than the second spring 48. When opening the bag, the dial lock 20 is unlocked as will be described later, and the push plates 35 and 36 are free to move in the left direction. Then, if the push lever pressing piece 32 is pushed leftward, the push lever collar 33 is pushed to the left via the first spring 34, and the push lever collar 33 is brought into contact with the push lever 31 at the push lever collar 33. The push lever 31 moves to the left together with the first push plate 35 and the second push plate 36, so that the push lever flange portion 33 can be released from the engaging portion 46 provided on the bottom plate 40 to open the side lock 30. . In this case, since the first spring 34 is stronger than the second spring 48, the two parts of the push lever 31 move together and can move to the left against the weak second spring 48.
[0010]
Dial lock is center lock is in the locked state, when the movement of the push plate 35 and 36 is blocked, the push lever hook 33 by pressing the push lever pressing piece 3 2 moves to the left is blocked since it is only the push lever pressing piece 3 2 against the first spring 34 is to move relatively leftward from the push lever hook 33. Therefore, even if the push lever 31 in the lock of the dial lock 20 is struck with a strong force, the push lever pressing piece 32 only moves to the left via the spring 34, and the impact reaches the dial lock via the push plates 35 and 36. There is no transmission.
[0011]
The structure of the center lock or the mechanism for preventing or releasing the movement of the push plate may be arbitrary, and although not the gist of the present invention, an example of the dial lock shown in FIGS. 2 and 3 will be described.
[0012]
4 is a plan view of a bolt to be combined with the dial lock 20, FIG. 5 is an end view of FIG. 4 viewed from the direction D, FIG. 6 is a cross-sectional view taken along line AA in FIG. Respectively.
[0013]
The dial lock 20 has dials 21 (four in the illustrated example), and a spacer 23 that is normally engaged with the dial 21 in the rotational direction is interposed between the dial 21 and the dial shaft 22. The spacer 23 has a notch 24 formed at a specific number on the dial. If the numbers on the dial 21 are arranged in a predetermined arrangement according to the password, the notch 24 of the spacer 23 is aligned. Then, the protruding portion of the bent portion 52 of the bolt 50 biased toward the dial by the spring engages with the notch 24 of the spacer 23, and the bolt 50 swings toward the dial 21 around the rotation center portion 55. Move. (FIG. 7) 51 indicates a hole into which the dial 21 enters.
[0014]
As shown in FIG. 7, when the dial lock 20 is in the unlocked state, the bolt 50 swings clockwise toward the dial 21, and the L-shaped operation portion 53 is also on the dial 21 side. In FIG. 2, the tip of the second push plate 36 can freely pass between the operation portion 53 of the bolt 50 and the dial box 26. That is, the push plates 35 and 36 and the push lever 31 can freely move to the left in FIGS.
[0015]
When the dial 21 is turned from this unlocked state, the bolt 50 is removed from the notch 24 of the spacer 23, pushed by the outer peripheral surface of the spacer 23, and rotated counterclockwise in FIG. 7, and the operation portion 53 is indicated by a dotted line. Come to the position shown. 2, 3, and 7, the end surface 54 of the operation portion 53 of the bolt 50 and the end surface 45 of the second push plate 36 come into contact with each other, and the push plate 36 moves to the left. Stop. As a result, as described above, the push plates 35 and 36 and the push lever collar 33 are prevented from moving to the left, and even if the push lever pressing piece 32 is pressed, only the push lever pressing piece 32 is pushed via the spring 34. It only moves relative to the lever collar 33. In FIG. 7, reference numeral 25 denotes a change lever for changing the number on the dial and the position of the notch in the spacer.
[0016]
2 and 3, reference numeral 60 denotes a signal indicating whether the dial lock 20 is unlocked or locked, and rotates around the support shaft 63 in conjunction with the bolt 50. 61 is a marking surface, and 62 is a marking portion. As shown in FIG. 6, the signal 60 moves to a position indicated by hatching or a dotted line in conjunction with the movement of the bolt 50, and whether the window 6 shown in FIG. 1 is unlocked or locked. Is indicated.
[0017]
Although the above description has been made with respect to the right side lock 30 in FIGS. 2 and 3, the same applies to the opposite side.
[0018]
【The invention's effect】
The side lock of the present invention is configured as described above. In the bag lock having the center lock and the side lock, even if a strong impact force is applied to the side lock during the lock of the center lock, the impact is transmitted to the center lock. The center lock will not be disturbed.
