Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the disclosure of an engagement tool used for closing bands, bags, various bags, etc., and particularly to the disclosure of an engagement tool that is particularly easy to attach and detach. It is something.

[Prior art and its problems] Conventional engagement devices of this kind have the intention of ensuring the engagement state by applying twisting motion to the hook member once engaged, or by locking, etc. This prevents the closing portion from being opened if it does not.

However, with the curl method, it is difficult to close and release the buckle with simple movements.
It was considered unsuitable for handling lower grade children, etc., and was also unsuitable for smooth release operations in emergencies.

In addition, the mechanism itself in such a twisting or locking structure is complicated, which makes it difficult to miniaturize the structure and is a major cause of failures in the operating parts.

[Means for Solving the Problems] The engaging tool according to the present invention has been devised in view of the inconveniences in the conventional engaging tool, and has an engaging recess facing laterally toward the head side. A male engaging tool consisting of a permanent magnet hook rod with a protruding hook portion 1a or a hook rod 1 containing a permanent magnet, and one or more holes through which the male engaging tool is inserted and retracted. a housing, and a slide plate 3 which is assembled in an overlapping state on a base constituting the housing and has a hole communicating with the hole described above.
The slide plate 3 has a knob 3c protruding outward from the housing, and a slide hole provided in either the base or the slide plate 3 is provided with a knob 3c on the other base or slide. A hook portion 1a of the male engaging tool is inserted into and locked with a mounting rod protruding from the plate 3, and is inserted into the hole of the housing and the hole of the slide plate 3.
This is an engagement tool in which the slide plate 3 is attracted to the side and the hole edge of the slide plate 3 is locked in the engagement recess of the hook portion 1a.

[Embodiment] Hereinafter, a typical embodiment of the engagement tool such as a buckle according to the present invention will be described with reference to the attached drawings.
This is a hook rod that is attached and fixed to a hook rod, and a hook rod 1a is provided on one side of the head side of the hook rod. A case is envisaged in which a permanent magnet 5 is enclosed as shown in FIG.

Next, 4 and 4' are housings, which are planned to be either made up of the board 2 itself constituting the buckle surface or provided with a separate case 6 on the surface of this board 2. It is constructed from any of the following materials.

The board 2 is provided with one or more fitting holes 2a through which the hook rod 1 is inserted, and a recess 2b for attaching the fabric 10 is formed at one side end. , a screw rod 7 or the like is used to ensure proper attachment to the fabric 10.

The case 6 described above is made of a non-magnetic material in the shape of an inverted dish with a hole 6a communicating with the substrate 2 and the slide plate 3, and has a seat plate 9 with the substrate 2 and the slide plate 3 inside. to close the bottom opening,
These are designed to hold and integrate the interior board 2 and the slide plate 3, and the claw pieces 6b on the edge of the opening in the case 6 are inserted and bent into the mounting holes 9a in the seat plate 9 to integrate them. This was intended for the purpose of

Further, the slide plate 3 is assembled to the board 2 in an overlapping state, and a slide hole 3b is opened in either the slide plate 3 or the board 2, and a bolt or the like is inserted and locked into the slide hole 3b. The mounting rod 8 is protruded from the other slide plate 3 or the board 2, and the slide plate 3 is restricted from sliding along the slide hole 3b, and is integrally provided with a knob 3c at one end. , and the other end is connected to the substrate 2
is in contact with the inner wall surface 2c of the recess 2b,
Sliding motions that go deeper into the body are regulated.

The slide plate 3 is provided with a hole 3a that communicates with the previous hole 2a, and the sliding end of the slide plate 3 with respect to the hole 2a, that is, the end of the slide plate 3, is brought into contact with the inner wall surface 2c. The holes 3a are constructed so as to overlap each other so that the surface of the slide plate 3 is not exposed to the surface of the hole 2a in this state, that is, the surface of the hole 2a is sufficiently opened.

In addition, the slide plate 3 is especially designed to move the hole edges of the holes 2a and 3a in the operating direction so that the end of the slide plate 3 slides and is immediately exposed on the surface of the hole 2a when the slide plate 3 is moved from its sliding end in the direction of pulling out the slide plate 3. 2a and 3a' are configured to overlap, and special consideration has been given to instantaneous movement and engagement.

Furthermore, in this sliding and engagement of the slide plate 3, the rear end of the slide plate 3 is positioned on the inner wall surface 2c, so that the sliding movement is directed only in the direction of the hook rod 1a. That is, in order to ensure the sliding movement of the slide plate 3, the hole edge 3a'' on the front side of the hole 3a, that is, in the direction of the knob 3c, is made wider than the hole edge 2a'' of the hole 2a with which it is communicated. A considerable magnetic distance is provided between the hook rod 1 and the hook rod 1 to be inserted.

[Function] The engaging tool such as a buckle according to the present invention has the characteristic structure described above, and the hook portion 1a of the hook rod 1 is moved in the inner direction of the movement of the slide plate 3, that is, opposite to the knob 3c. By fitting the slide plate 3 into the holes 2a and 3a in the direction of the slide plate 3, the slide plate 3 is pushed by the end of the hook rod 1 to allow the hook portion 1a to enter, and the pressing force is released by the hook portion 1a entering the slide plate 3. The hook rod 1
It is attracted toward the hook portion 1a with the attraction force of the permanent magnet, and is tightly engaged with the hook portion 1a.

[Effects of the Invention] The engaging tool according to the present invention has the characteristic structure described above, in particular, by simply inserting the hook rod 1 into the holes of the base plate 2 and the slide plate 3, the slide plate 3 can be attached to one side of the hook rod. The hook portion 1a is reliably engaged with the surface of the slide plate 3 by suction, and its slippage is reliably prevented, and the release operation is easily performed by picking the slide plate 3 and removing it from the hook portion 1a by the push-in operation of the slide plate 3c. The engagement and release operations are mostly one-touch operations, making it suitable for lower grade children and also usable as a buckle for release operations in emergencies.
