【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of the present invention. The buckle of this embodiment has a resin male member 10 attached to the end of the belt 1 of one member connected to each other. The other member is made up of a resin female member 11 attached to the end of the belt 2 and into which a male member 10 is inserted and engaged. The male member 10 is composed of a connecting body 12 provided at the base end and a locking body 13 that engages with the female member 11. The connecting body 12 includes a belt mounting portion 14, a pair of side portions 15 located at both ends of the belt mounting portion 14, and a base portion 16 pivotally supported between the pair of side portions 15. The base 16 has pivot shafts 17 formed at both ends thereof, and is pivotally supported by a shaft hole 18 formed in the pair of side portions 15. Further, a mounting hole 21 into which the connecting portion 20 of the locking body 13 is inserted is provided at the center of the base portion 16.

The locking body 13 is provided with a connecting portion 20 at its base end portion and an operating portion 22 at its tip end portion. Further, a pair of elastic pieces 23 are integrally formed on both sides of the locking body 13 so as to project. As shown in FIGS. 1 and 3, a split piece 26 split by a cross-shaped split groove 25 is formed at the connecting portion 20 at the base end of the locking body 13, and at the end of the split piece 26. The bulged portions 29 are formed so as to be convex outward. A step portion 30 that engages with the bulging portion 29 is formed at a corresponding one end portion of the mounting hole 21. A locking portion 31 is provided at an end edge portion of the operation portion 22 on the base end side, and the locking portion 31 is formed obliquely in the back surface direction and has a predetermined curvature radius.

The female member 11 includes a main body 33 and a belt mounting portion 34 formed at one end of the main body 33. The main body 33 includes a space in which the locking body 13 can be housed. The storage portion 32 is formed so as to open in a predetermined range on the side surface of 33. On the front and back surfaces of the central portion of the main body portion 33, operation holes 35 are formed on the front and back surfaces that penetrate the front and back surfaces and have an inner diameter slightly larger than that of the operation portion 22 so that the operation portion 22 can be inserted from the storage portion 32 side. . Engagement portions 36, which are formed in a concave shape from the periphery and engage with the locking portions 31, are formed at the peripheral edge of the operation hole 35 on the side of the opening 32a of the housing 32. Each engaging portion 36 is formed in an arcuate recess having a radius of curvature equal to that of the engaging portion 31, and is formed in a tapered shape that matches the taper of the engaging portion 31. The tapered portions 36 and 36 are provided so as to be in surface contact with each other. In the storage portion 32, the elastic piece 23 elastically contacts the inner wall surface of the storage portion 32 with the locking body 13 inserted, and the locking portion 31 is reliably positioned in the operation hole 35. Thus, the operation unit 22 is biased. Since the operation hole 22 is slightly larger than the operation portion 22, an escape portion 35a is formed for retracting the operation portion 22 to the disengagement position even when engaged.

Next, a method of using the buckle of this embodiment will be described below. First, in order to mount the male member 10 on the female member 11, the stopper 13 is inserted into the housing 32 through the opening 32 a of the female member 11. At this time, while the operating portion 22 faces the inner surface of the housing portion 32, the elastic piece 23 pushes the operating portion 22 against the inner surface of the housing portion 32, and further pushes the operating portion 22 to the operating hole 35, and The operation portion 22 is spontaneously positioned in the operation hole 35. Then, in the state in which the operating portion 22 is located in the operating hole 35, the tapered portions of the locking portion 31 and the engaging portion 36 are in surface contact with each other, and the engagement is ensured.

In this state, as shown by the chain double-dashed line in FIG. 2, the male member 10 has a contact surface between the engaging portion 31 and the engaging portion 36 within the opening 32a of the accommodating portion 32 of the female member 11. It is possible to swing along a predetermined angle. Further, the base portion 16 having a rotation axis orthogonal to the swing center axis is rotated by the shaft portion 17 and the shaft hole 18, and the connecting portion 20 and the mounting hole 21 are arranged in the rotation axis direction. It is rotatable about the orthogonal axes.

Next, when the connection between the male member 10 and the female member 11 is released, the operation portion 22 of the male member 10 is first pressed from the operation hole 35, contrary to the operation at the time of connection described above. , Is pushed into the storage portion 32 of the female member 11 to release the engagement between the locking portion 31 and the engaging portion 36. After this, the connection is easily released by pulling the male member 10 outward.

According to the buckle of this embodiment, when the male member 10 and the female member 11 are connected to each other, the engaging surfaces thereof are in surface contact with each other, and the contact state of the uneven surfaces having the same curvature is obtained. It is rotatable around the surface. Therefore, the strength of the contact portion is high, the engagement portion is less likely to be damaged, and the buckle itself is not subjected to excessive force. Further, since the operation holes 35 are formed on the front and back sides, it is not necessary to care about the front and back sides of the female member 11, which is convenient for use.

Next, a second embodiment of the present invention will be described with reference to FIG. Here, the same members as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. In the bag of this embodiment, the connecting body 12 of the male member 10 includes a belt mounting portion 14, a pair of side portions 15 positioned at both ends of the belt mounting portion 14, and between the pair of side portions 15. It is composed of a fixed base portion 42. An operating portion 22 is formed at the tip of the locking body 13, and an end edge of the operating portion 22 on the side of the connecting body 12 is curved outward with a predetermined curvature and is formed in a taper shape toward the back surface. The locked portion 31 is provided.

Further, the female member 11 is provided with a main body portion 33 and a belt attachment portion 34, and the main body portion 33 is composed of a space capable of accommodating the locking body 13 and is located within a predetermined range on the side surface of the main body portion 33. An open storage part 32 is formed. An operation hole 45, which is larger than the operation unit 22 and allows the operation unit 22 to be inserted from the storage unit 32 side, is formed on the surface of the central portion of the main body 33. The operation hole 45 has a shape that opens from the central portion of the main body 33 to the belt mounting portion 34, and the apex of the operation hole 45 on the male member side is in surface contact with the locking portion 31 of the male member 10. A concave engaging portion 46 is formed. The operating hole 45 is much larger than the operating portion 22, and the escape portion 45a of the operating portion 22 is sufficiently formed.

Also in this embodiment, with the male member 10 connected to the female member 11, the engaging portion 31 and the engaging portion 46 are engaged in surface contact with each other, and the engaging surface has a predetermined curvature. The male member 10 and the female member 11 are formed so as to be relatively rotatable.

The buckle of the present invention is not limited to the above-mentioned embodiment, and the locking portion and the engaging portion may have a shape in which they are in surface contact with each other and are rotatably engaged. Further, the shapes of the operation member and the operation hole can be appropriately set, and the shapes are not limited. Further, in the first embodiment, the operation hole may be provided on one surface of the front surface and the back surface, and the shape of the elastic piece is such that the operation portion can be biased outward by pressing the inner surface of the storage portion of the female member. I wish I had it. That is, without using the elastic piece, it can be performed between the base portion of the locking body and the connecting portion on the operating portion side, and the shape of the elastic piece is such that a tongue-shaped piece is provided on the lower surface of the locking body, Alternatively, various modifications can be made so that the elastic piece is formed from below toward the locking body. Further, the buckle of the present invention may be a so-called soybean paste that is fixed to a cloth such as a bag. In this case, the female member does not have a belt attachment part, but is provided with legs that are attachment parts for attaching to the fabric, and the tip of the leg is crimped on the opposite side across the fabric of the female member and the bag. It is provided with a stop member that can be fixed by fixing.

[Effect of device]

 In the buckle of this invention, since the locking portion and the engaging portion are in surface contact with each other at the contact surface having a predetermined curvature in the state where the male member and the female member are connected, the force applied to the male member and the female member is not affected. Therefore, excessive force is not concentrated on a part of the locking part. Moreover, both of them are relatively rotatable, and are rotated by being guided by the contact portions of the engaging portion and the engaging portion, so that the rotating operation is also smooth.
