Abstract

(57) [Summary] [Purpose] To prevent a gap from being generated between the lid and case body. [Structure] Before the locking device 2 is locked, that is, when the operating portion 23 of the lock portion 22 is pushed upward by a finger, dimensional error of each portion between the lid body 12 and the case body 11 when the lid body 12 is closed. However, a gap C may occur due to misalignment of the assembly position, deformation of each part, etc. (Fig. A). When the finger is released from the operation portion 23, the lock portion 22 is pressed by the urging force of the spring 25.
Are pulled obliquely downward along the guide pin 26.
In the middle of this, the hook portion 24 is hooked by the hooking piece 21, and the lock portion 22 is further lowered. Then, when the lid 12 comes into contact with the case body 11, the lock portion 22 stops (FIG. B). As a result, the gap C is eliminated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lock device for preventing the lid body from being opened accidentally when the lid body such as a storage case is closed.

[0002]

[Prior Art]

 When storing or transporting articles, a storage case 1 as shown in FIG. 3 (a) is often used. Such a storage case 1 has a lid body 12 which is attached to a case body 11 by a hinge (not shown) or the like so as to be openable and closable. A lock device 2 is attached to the mating portion between the case body 11 and the lid 12.

As shown in FIG. 1B, the lock device 2 is composed of a locking piece 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 to the left and right, and is biased by a spring (not shown) or the like toward the hooking piece 21. Then, the hook portion 24 provided on the upper side of the lock portion 22 is hooked on the hooking piece 21 so that the lid 12 is prevented from being opened accidentally.

[0004]

[Problems to be solved by the device]

 In the storage case 1 described above, a gap C may occur between the case body 11 and the lid body 12 with the lid body 12 closed. This is because the case body 11 or the lid 12 has a dimensional error, the mounting position of the lock device 2 is improper, and both the case body 11 and the lid 12 are thin. This is because it will be deformed. The conventional lock device 2 cannot prevent such a gap C from occurring.

Therefore, the present invention solves the above-mentioned problems, and proposes a locking device such as a lid that can prevent a gap between the case body and the lid. is there.

[0006]

[Means for Solving the Problems]

 In order to solve the above-described problems, the present invention provides a locking device such as a lid that is attached to prevent the lid from accidentally opening when the lid such as a storage case is closed. A locking means that can be attached to the body, a locking means that can be movably attached to a storage case, etc., and that can be locked to the locking means when the lid is closed, and a lid closing direction. Further, it is characterized in that a biasing means for biasing the locking means is provided to eliminate a gap generated between the lid body and the storage case when the lid body is closed.

[0007]

[Action]

 As shown in FIG. 2 (a), before the locking device 2 is locked, there may be a gap C between the lid body 12 and the case body 11 when the lid body 12 is closed. At this time, the operating portion 23 of the lock portion 22 is pushed upward by the finger. When the finger is released from the operation portion 23, the lock portion 22 is pulled down diagonally along the guide pin 26 by the urging force of the spring 25. In the middle of this, the hook portion 24 is hooked on the hooking piece 21, and in this state, the lock portion 22 further descends. Then, as shown in FIG. 7B, the lock portion 22 stops when the lid body 12 contacts the case body 11. As a result, the gap C is cleared.

[0008]

【Example】

 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 designated by the same reference numerals and detailed description thereof 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 is attached to the case body 11 on one side with a hinge (not shown). A lock device 2 is attached to the opposite side of the hinge. The lock device 2 includes a hooking piece 21 attached to the lid 12, a lock portion 22 attached to the case body 11, and a biasing force of the lock portion 22 in the lid closing direction of the lid 12. It is composed of a spring 25 and a guide pin 26 attached to the case body 11 to regulate the moving direction of the lock portion 22.

The lock portion 22 is relatively long and is arranged along the lateral direction of the case body 11, and guide holes 27 of an appropriate length are provided on both end sides as shown in FIG. 2A. It is provided so as to be inclined along the biasing direction of 25. A guide pin 26 fixed to the case body 11 is slidably inserted into the guide hole 27. A head portion 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 lid closing direction of the lid body 12 by the spring 25 interposed between the lower central portion of the lock portion 22 and the case body 11. The lock portion 22 is provided with an operation portion 23, and by operating this with a finger, it becomes easy to push up the lock portion 22 against the biasing force of the spring 25. On the upper side of the lock portion 22, a hook portion 24 that can be hooked on the hooking piece 21 when the lid body 12 is in the closed state is projected.

Now, it is assumed that when the lid 12 is closed, a gap C is generated due to dimensional error of each part, displacement of the mounting position, deformation of each part, etc. in a state where the lock device 2 is unlocked. At this time, the operation portion 23 of the lock portion 22 is pushed upward by a finger or the like. When the finger is released from the operation portion 23, the lock portion 22 is pulled down obliquely by the urging force of the spring 25. Then, the hook portion 24 is hooked on the hooking piece 21. At this time, there is still a space between the guide pin 26 and the guide hole 27, and the lock portion 22 descends while being retained by the retaining piece 21. Then, as shown in FIG. 3B, the lowering of the lock portion 22 is stopped when the lid body 12 contacts the case body 11. As a result, the gap C between the lid 12 and the case body 11 is eliminated.

[0012]

[Effect of the device]

 As described above, the present invention can be attached to the lid body by the locking device such as the lid body that is attached to prevent the lid body from being opened accidentally when the lid body such as the storage case is closed. A locking means that can be movably attached to a storage case and the like, a locking means that can be locked to the locking means when the lid is closed, and a locking means in the lid closing direction. An urging means for urging is provided 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 there is a dimensional error in each part such as the storage case, the mounting position of each part is slightly deviated, or each part is deformed, the space between the lid body and the case body is increased. There is an effect such that it is possible to prevent the formation of a gap in.
