Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a latching device that can easily lock the opening of a floppy disk storage case or the like.

[Conventional technology]

Floppy disks, which are used as simple recording media for computers, word processors, etc., can be stored in a stationary storage case or a simple bag-like storage case made of synthetic resin board. Often used for storage and transportation. Such a floppy disk storage case requires a simple locking device to prevent the opening from opening accidentally. For this reason, conventional storage cases have been provided with a latching device consisting of a hook and loop fastener, hook, or the like.

[Problem that the invention attempts to solve]

However, if a floppy disk is used by an inexperienced person, there is a risk that the recorded contents may be accidentally damaged, and since the recorded contents such as data can be easily copied, floppy disks containing the original programs are not used. Even if the storage case for storing floppy disks containing important data is not very secure, if the opening can be easily locked, it will prevent careless use or easy copying. be. However, such locking cannot be achieved with conventional latching devices such as hooks and hooks.

Taking these circumstances into consideration, the present invention has a simple structure that allows the opening to be easily locked, instead of using hook-and-loop fasteners or hooks. It is an object of the present invention to provide a latching device that can be applied to various types of latching devices.

[Means for solving problems]

In order to solve the above problems, the latching device according to the present invention includes a plate-shaped lock release piece, a plate-shaped insertion piece attached to the latching side and having a latching hole at the tip. It is provided on the fixed side and has an insertion opening for inserting the insertion piece and the lock release piece, and inside this insertion opening there is a return made of an elastic body whose tip is cut and raised in the direction in which the insertion piece is inserted. The insertion portion has a stop portion formed therein.

[Effect]

According to the above configuration, when the insertion piece is inserted through the insertion opening of the fixed side insertion part, the tip of the return part made of an elastic body is latched to the latching hole of the insertion piece. Then, even if the insertion piece is tried to be pulled back, it will not come out from inside the insertion portion, and the fixed side and the hooking side will be locked.

Next, when inserting the lock release piece into the gap between this insertion slot and the insertion piece inserted into this insertion slot, which is the base side of the return part, the tip of this lock release piece will be inserted into the insertion part. Since the tip of the return portion cut and raised in the direction of movement is pushed back toward the base side, the return portion is no longer latched to the latching hole of the insertion piece when the lock release piece is fully inserted. Therefore, if you pull back the insertion piece, it will easily come out from inside the insertion part.
The fixed side and the hanging side are separated.

In addition, the lock release piece is prepared separately from the latching side and the fixed side, or it can be stored on the latching side or the fixed side, or it can be inserted into the insertion opening of the insertion section and removed from the latching side or the fixed side. It may be attached to the fixed side.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In this embodiment, as shown in FIG. 1, a latching device 3 is attached to a storage case 2 that stores floppy disks 1. This storage case 2 is
A box-shaped part 4 in which a floppy disk 1 is housed is surrounded by a cover 5 made of a synthetic resin plate, and an insertion part 6 is attached to the bottom of the box-shaped part 4 to which one end of the cover 5 is fixed so as to wrap around it. is embedded, and an insertion piece 7 is attached to the other end side of the cover 5 where the folded portion can swing as a hook side. The insertion portion 6 has an insertion port 8 opened in the cover 5 above the embedded position. The lock release piece 9 inserted into the insertion opening 8 is a plate made of rigid synthetic resin, and is prepared separately. Insert piece 7
is a plate made of rigid synthetic resin,
Latching holes 10, 10 are provided at the downwardly facing tip, and the upper base is fixed and protrudes inside the other end of the cover 5. In addition, in this embodiment, when the opening of the storage case 2 is closed, the other end of the cover 5 closes the insertion opening 8 of the insertion portion 6, so that the other end of the cover 5 is A lock release piece insertion hole 11 for inserting the lock release piece 9 into the insertion opening 8 is opened on the end side.

As shown in FIG. 2, the insertion section 6 includes the bottom plate of the box-shaped section 4 and the cover 5, which continue downward from the upper insertion opening 8.
A gap-like space between the two is surrounded by an embedded plate 12. The embedded board 12 is made of a synthetic resin board having a certain degree of rigidity and elasticity, and has a return portion 13 cut and raised from the wall surface side along the cover 5. The return portions 13 are formed by cutting and raising the wall surface of the embedded plate 12 at positions corresponding to the latching holes 10, 10 when the insert piece 7 is inserted into the insertion portion 6. The wall surface of 12 is cut out into a corner piece large enough to be hooked into the hooking hole 10, leaving only the upper end side, and by bending this upper end side, the lower tip is raised toward the box-shaped part 4 side. In this case, if an escape hole is provided in the wall surface of the embedding plate 12 on the side along the box-shaped portion 4 and the tip of the return portion 13 is inserted into this escape hole, the insertion piece 7 can be inserted. This makes it more secure to lock when

In the above configuration, as shown in FIG. 3, the opening of the storage case 2 is closed and the insertion piece 7 is inserted into the insertion opening 8.
When the insertion piece 6 is inserted into the insertion portion 6, the return portion 13 whose tip is cut and raised in the direction of advancement of insertion is once pushed back to the tip of the insertion piece 7, and then latched into the latching hole 10 by this elasticity. do. Then, this return part 1
3 in the locking hole 10, even if the insertion piece 7 is pulled back, it will no longer come out of the insertion portion 6, and the opening of the storage case 2 will be locked.

Next, as shown in FIG. 4, when the lock release piece 9 is inserted into the insertion portion 6 from the insertion opening 8 through the lock release piece insertion hole 11, the tip of the lock release piece 9 is inserted into the insertion piece 7. As in the case of the tip, push back the return part 13 and remove the tip of this return part 13 from the hook hole 10. Therefore, when the lock release piece 9 is fully inserted, the locking part 13 is released from the locking hole 10, so if the insertion piece 7 is pulled back in this state, the insertion part can be easily removed. 6 and the opening of the storage case 2 can be opened.

In this embodiment, the opening of the storage case 2 is always locked when it is closed, which may be inconvenient when the floppy disk 1 is used.
For this reason, for example, this latching device 3 can be used in combination with a hook-and-loop fastener or a hook, and the insertion piece 7 protruding from the other end of the cover 5 can be folded freely. When the opening is not inserted into the opening 6, the opening can be hooked only with a hook-and-loop fastener or hook as in the conventional case. Further, in this embodiment, the insertion piece 7, the unlocking piece 9, etc. are made of synthetic resin plates, but the material is not limited to this, and any material having a certain degree of rigidity, such as paper, may be used. Good too. Furthermore, if the insertion piece 7 and the unlocking piece 9 are formed into a thin plate shape, and the insertion part 6 is also formed into a bag shape made of a thin synthetic resin plate, it can be attached to the opening of a thin object such as an envelope. It becomes possible.

[Effect of idea]

As described above, the latching device according to the present invention includes a plate-shaped lock release piece, a plate-shaped insertion piece attached to the latching side and having a latching hole at the tip, and a plate-shaped insertion piece attached to the latching side and provided with a latching hole at the tip. It has an insertion opening for inserting the insertion piece and the lock release piece, and a return portion made of an elastic body whose tip is cut and raised in the direction in which the insertion piece is inserted is formed inside this insertion opening. It consists of an insertion section. As a result, once the locking side insertion piece is inserted into the fixed side insertion part, this insertion piece cannot be pulled out from the insertion part unless the lock release piece is inserted. Therefore, the fixed side and the latching side can be easily locked by a simple configuration of the insertion piece provided with the latching hole and the insertion portion formed with the return portion. For this reason, in addition to the floppy disk storage case shown in the conventional technology, bags, files, address books, etc.
If used as a hanging device for diaries, certificate books, envelopes, books, etc., it can be used to easily protect confidentiality without attaching a large-scale lock.It can also be used as a hanging device for belts such as watches, duvet covers, etc. If used for this purpose, it is possible to securely lock without getting in the way.
