BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for preventing a cover such as a storage case from being opened carelessly when the cover is closed.

[0002]

2. Description of the Related Art When storing and transporting articles, a storage case 1 as shown in FIG. Such a storage case 1 includes a lid 12 which is attached to a case body 11 by a hinge (not shown) so as to be freely opened and closed.
have. A lock device 2 is attached to a joint between the case body 11 and the lid 12.

As shown in FIG. 1B, the lock device 2 includes a hook 21 attached to the lid 12 and a lock portion 22 attached to the case body 11. The lock portion 22 is integral with the operation portion 23, is movable left and right, and is urged toward the hooking piece 21 by a spring (not shown) or the like. The hook 24 provided on the upper side of the lock portion 22 is hooked on the hook 21 so that the lid 12 is not opened carelessly.

[0004]

In the storage case 1 described above, the case body 11 and the cover 1 are closed with the cover 12 closed.
There may be a gap C between the two. This is because the case body 11 or the lid 12 has a dimensional error, the mounting position of the lock device 2 is inappropriate,
This is because both the case body 11 and the lid body 12 are formed thin and may be deformed. The conventional locking device 2 cannot prevent such a gap C from being generated.

[0005] In view of the above, the present invention solves the above-mentioned problem, and proposes a locking device such as a lid which can prevent a gap between the case main body and the lid. .

[0006]

In order to solve the above-mentioned problems, according to the present invention, when a cover such as a storage case is closed, the cover is attached to prevent the cover from being opened carelessly. In a locking device for a body or the like, a locking means attached to a lid, a locking means movably attachable to a storage case or the like, and locked to the locking means in a closed state of the lid, Biasing means for biasing the locking means in the closing direction of the cover, a guide hole formed in the locking means and inclined along the biasing direction of the biasing means, provided in a storage case or the like, and slidable in the guide hole. A guide pin is freely inserted, and when the lid is closed, the locking means moves obliquely along the biasing direction of the biasing means and locks the lid by locking the locking means. It is characterized by the following.

[0007]

As shown in FIG. 2A, a gap C may be formed between the case body 11 and the lid 12 in the closed state before the locking device 2 is locked. At this time, the lock portion 22
Is pushed upward by a finger. Here, when the finger is released from the operation unit 23, the lock unit 22 is pulled down obliquely downward along the guide pin 26 by the urging force of the spring 25. The hook portion 24 is hooked on the hooking piece 21 on the way, and the lock portion 22 further descends in this state. Then, as shown in FIG.
The lock part 22 stops at the point of contact. Thereby, the gap C is eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a lock device such as a lid according to the present invention will be described in detail with reference to the drawings. The same parts as those described above are denoted by the same reference numerals, and detailed description is omitted.

FIG. 1 shows a storage case 1 to which a lock device 2 such as a lid according to the present invention is applied. The lid 12 of the storage case 1 has a hinge (not shown) on one side and a case main body 11.
Attached to. Locking device 2 on the other side of the hinge
Is attached. The lock device 2 includes a lid 12
A lock piece 21 attached to the case body 11, a lock portion 22 attached to the case body 11, and the lock portion 22
2 includes a spring 25 that urges in the closing direction and a guide pin 26 that is attached to the case main body 11 and regulates the moving direction of the lock portion 22.

The lock portion 22 is relatively long and the case body 1
1 are arranged along the lateral direction, and two ends
As shown in (a), a guide hole 27 having an appropriate length is provided so as to be inclined along the biasing direction of the spring 25. A guide pin 26 fixed to the case body 11 is slidably inserted into the guide hole 27. A head 28 is provided at the tip of the guide pin 26 so that the lock portion 22 does not come off. Further, the lock portion 22 is constantly urged in the closing direction of the lid 12 by the spring 25 interposed between the lower central portion of the lock portion 22 and the case body 11. The lock unit 22 is provided with an operation unit 23. By operating the operation unit 23 with a finger, it becomes easy to push up the lock unit 22 against the urging force of the spring 25. On the upper side of the lock portion 22, the lid 1
When the lid 2 is in a closed state, a hook portion 24 that can be hooked on the hooking piece 21 is protrudingly provided.

When the lid 12 is closed and the lock device 2 is released, a gap C is generated due to a dimensional error of each part, a displacement of a mounting position, a deformation of each part, and the like. At this time, the operation unit 23 of the lock unit 22 is pushed upward by a finger or the like. Here, the operation unit 23
When the finger is released from the lock portion 2, the urging force of the spring 25
2 is pulled down diagonally. Then, the hook portion 24 is hooked on the hooking piece 21. At this time, there is still room between the guide pin 26 and the guide hole 27, and the lock portion 22 descends while being hooked on the hooking piece 21. Then, the lowering of the lock portion 22 is stopped when the lid 12 contacts the case body 11 as shown in FIG. Thereby, the gap C between the lid 12 and the case main body 11 is eliminated. Further, the cost can be reduced by reducing the number of parts.

[0012]

As described above, the present invention relates to a locking device such as a lid attached to prevent the lid from being opened carelessly when the lid such as a storage case is closed. Locking means that can be attached to the body, locking means that can be movably attached to a storage case and the like, and that can be locked to the locking means when the lid is closed, and locking in the closing direction of the lid An urging means for urging the means is provided so as to eliminate a gap generated between the lid and the storage case when the lid is closed.

Therefore, according to the present invention, even if each part such as the storage case has a dimensional error, the mounting position of each part is slightly shifted, or each part is deformed,
There is an effect that a gap can be prevented from being formed between the lid and the case body. Also, since the lid can be locked or released by moving only the lock portion,
The number of parts is reduced, the assembling work is facilitated, and the manufacturing cost can be reduced.
