A slide buckle 27 that slides on the upper part 9 is provided. A guide groove 26 is formed on the back surface of the slide buckle, and the projection 25 on the upper surface of the swing plate fits in this groove. When the slide buckle is slid downward from the state shown in FIG. 14, the protrusion 25 receives a lateral force in the figure, so that the swing plate 28 opens left and right, and FIG.
It becomes the form shown in 5. On the back side of the swing plate 28,
The concavo-convex pattern is formed, and the concavo-convex pattern that is inclined with respect to the fixed-side concavo-convex pattern as in the present example has the concavo-convex portion meshed and firmly attached, as in the above example.

In FIG. 16, a base plate having an elliptical shaft portion 31 formed on the upper surface is divided at the center, and is constructed as a swing plate 28 that opens and closes left and right around a bendable connecting portion 30 as an axis. A dial body 24 is rotatably connected to the upper surface of the elliptical shaft portion. The horizontally wide elliptical shaft portion 31 is pressed from the left and right directions by rotating the dial body 24 having the bearing portion of the same shape by 90 degrees, and as shown in FIG. 17, both swing plates are closed. Becomes When the dial body 24 is rotated 90 degrees from this state, the swing plate 28 returns to the open shape by the repulsive force of the elastic connection portion 32. An uneven pattern is formed on the back surface of the swing plate 28, as in the above example.

In FIG. 18, by pressing the pressing plate 8 formed in a mountain shape, the positions of the four connected swing plates 28 change on the same plane, and at the same time, the stopper bar 33 is caught by the stopper 34. It can be fixed in place. FIG. 19 shows that the pressing plate is pushed in,
It is a movable side fastening tool in a fastening state. The stopper rod 33 locked in this state becomes free by pressing the release button 35, and returns to the original state according to the stress of the elastic connection portion 32 provided on the swing plate. In the returning state, the concave-convex patterns on the back surfaces of the four swing plates are in a synchronized position.

The movable side fastening device of the example shown in FIGS. 14 to 19 is a swing plate 28 having an uneven pattern.
Is inclined on the same plane.
The tilted concave-convex pattern has an effect of narrowing the concave portion and widening the convex portion as shown in FIG. 20 with respect to the fixed-side concave-convex pattern. Further, the pitch of the inclined concave-convex pattern also changes with respect to the fixed-side concave-convex pattern.

In the above description, in the case of using the pressing plate, the pressing plate 8 is
Some locking part is provided so that the position is fixed, but when the locking part is removed, the pressing plate is
The elastic force restores the original state. It is desirable that the movable concave-convex pattern surface in the restored state is in a state in which the pattern is synchronized. In addition, even if these do not self-recover by using the dial body 24 and the slide buckle 27,
In order to clarify the return position, it is desirable to provide stop position sensing means using a step such as a click stop so that the concavo-convex pattern surface is in a synchronized state at the same position.

Next, a concrete example of the uneven pattern surface will be described. In the description so far, the concave-convex pattern shown in the drawings is a shape in which rail-shaped convex portions are arranged in parallel, but the concave-convex pattern shown in FIG. This is an example in which 36 is forested at a constant pitch.
In FIG. 22, rectangular protrusions 36 having an inverted trapezoidal cross section are arranged at a constant pitch. FIG. 23 shows an example in which bent rail-shaped convex portions are arranged in parallel at regular intervals. When the concavo-convex pattern surfaces having the projections or convex portions as shown in the figure are engaged and fixed, the engaging surface can exhibit a strong locking force in the front, rear, left and right.

FIG. 24 shows a specific cross-sectional shape of the projections and projections formed on the uneven pattern surface.
When the movable side concave-convex pattern and the fixed side concave-convex pattern have the same concave-convex shape, the convex part of the convex-concave pattern has a size that fits into the concave part, and the convex part has a convex part. It is necessary that a constricted portion having a cross section smaller than that of the portion is formed, and the side surface positions of the concavo-convex portion engage with each other. Within this range, the protrusion may have a shape other than that of this example as long as the protrusion has a constricted portion formed at the base. Further, when the movable-side concave-convex pattern and the fixed-side concave-convex pattern have different shapes, the shapes may be those shown in FIG. 25 and FIG. 26, and various variations are conceivable. It suffices that the portion fits in and the concavo-convex portion is formed with a constricted portion and a bulged portion as described above, and the constricted portion and the bulged portion engage with each other. A rail-shaped convex portion provided on one engaging surface and a mushroom-shaped projection provided on the other surface will also function.

The concavo-convex pattern is generally formed on a flat surface, but as in the example shown in FIG. 27, the fixed-side engaging surface and the movable-side engaging surface are formed as curved surfaces that are in close contact with each other. It is also possible to arrange the uneven pattern on the curved surface.

As shown in FIG. 28, the fixed-side engaging surface may be provided with a cut for facilitating bending, and when the present engaging device is attached to a member made of a flexible material, The feeling of strangeness is reduced.

The fastening device is made of various synthetic resin, metal, wood,
It can be formed of various materials such as, and the material is not particularly limited.

[0025]

The fastening device of the present invention can adjust the fastening position for each pitch of the concave-convex pattern of the fastening surface.
Since the engaging surfaces are configured to engage with each other, they have a very strong fastening force. Further, since the fastening action only moves a part of the movable side fastening tool by about one pitch of the concavo-convex pattern, a very small force is required for fastening. The fixed side fastening surface has a simple shape and can be made very thin, and the stripe-shaped concavo-convex pattern has a neat design, so it can be applied to items that emphasize fashionability. The fastening tool can be integrally molded with resin, and when the article to be attached is made of synthetic resin, it can be simultaneously formed including the fastening tool. The attachment / detachment of the present attachment can be performed with one touch by operating the pressing plate of the movable attachment. In addition, by standardizing the uneven plate, it can be widely used as a fastening method with high versatility.
