(B) The other of the male and female hooks is
(I) a base having grooves in the longitudinal direction;
(Ii) an elastic body housed in the groove;
(Iii) connected to the elastic body, and the other button corresponding to one of said male and female button,
(Iv) a lid provided with a long hole for securing a storage space for the elastic body between the base and exposing the other of the male and female buttons ;
It is comprised from these.

  According to the present invention, since a combination of male and female buttons is used in place of the combination of the hook member and the bar member in the prior art, operation is easy even for children and persons with disabilities. Moreover, once hooked, unless both are intentionally removed, the engagement between them cannot be released by chance. Furthermore, if it is supplied to the market together with the above-mentioned conventional technology, the range of choices of consumers is expanded.

The relationship between male and female hooks is relative. When the male button one of said male and female hooks, the other male and female hook is the female button corresponding to the male button. However, when one of the male and female hooks is a female button, the other of the male and female hooks is a male button corresponding to the female button.

As the elastic body (B) (ii) , various types can be used. For example, a coil spring, a leaf spring, a bar spring, a resin spring, etc., and a metal, rubber, resin, fluid, etc. can be used as the material. As the coil spring, a tension spring or a compression spring can be used.

In particular, when the spring is molded from resin, it is more convenient to perform integral molding.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a perspective view of an assembled state of the hook according to the first embodiment. 2A is a plan view of a female hook, FIG. 2B is a side view thereof, FIG. 3C is a right side view thereof, and FIG. 3 is an enlarged view of a male and female button engaging portion. FIG. 4 is a longitudinal cross-sectional view of the engagement button in the longitudinal direction in the state (a) before sliding and (b) after sliding.

  The male hook 10 is a male member of a snap button attached to one end 11 of an open end of clothing or the like. There are engaging projections 12 on the inner side (lower side), and the decorative button surface 13 is on the outer side (upper side). The external (upper) button surface 13 is for decorative purposes only and can be omitted.

  The female hook 20 is attached to the other end 21 (FIG. 4) of the open end, and is detachably locked to the male hook 10. The female hook 20 includes a base portion 22, an elastic body 23, a female member 24, and a lid portion 25.

  The base portion 22 has a groove 26 in the longitudinal direction, and has a leg portion 27 for attaching to the fabric. In this embodiment, the base has an outline with a width of 11.5 mm, a length of 31 mm and a thickness of 2.4 mm. Further, a concave groove 26 having a uniform cross-sectional shape and a width of 6.0 mm and a depth of 1.8 mm is formed in the central portion in the longitudinal direction. A claw-like projection 28 is provided at one end of the groove for the purpose described later. The leg part 27 is provided with a sharp knife-like piece on each of the left and right ends. When attaching to one end of the open end of clothing or the like, this leg 27 is protruded against the fabric, a seat plate 29 (FIG. 4) is applied from the back, and it is bent and crimped on the back of the penetrating fabric.

  The elastic body 23 is a coil spring set so that a metal wire is accommodated in a groove 26 formed in the female hook. One end of the coil spring is fixed to the above-described claw-like protrusion 28 of the base, and the other end is fixed to a female member 24 described below. In this embodiment, a compression spring that contracts when a force is applied is used.

  The female member 24 corresponds to the male member 12 of the button, and is a block body 31 having a snap button receiving portion 30. As shown in the enlarged view of FIG. 3, one side portion 31 a of the block body bulges, and one end of the coil spring 23 is fixed to the block body 31, so that it can move in conjunction with the coil spring 23. As shown in FIG. 3, it is preferable that the opening 32 of the snap button receiving portion 30 is slightly decentered in order to secure the fitting.

  The lid portion 25 has a substantially elliptical plate shape, but has a side portion 33 for connection to the base portion 22. When combined with the base 22, a storage chamber for the spring is formed between them. Further, the lid portion 25 is provided with a long hole 34 that keeps the female member 30 exposed.

  The operation of the hook device of the present invention will be described based on FIG. The wearer engages the button engaging protrusion 12 of the male hook attached to one open end portion of the waist of clothes and the button receiving portion 30 of the female hook 20 attached to the other open end portion of the waist of clothing with a finger. (See arrow in FIG. 1).

  When the abdominal pressure increases (for example, when the abdomen is full after a meal or when a force is applied to the abdomen during bending or stretching), the engaged male and female buttons resist the elastic force of the elastic body 23 and oblong holes. It moves along 34, and the size of waists, such as clothes, is increased (FIG.4 (b)). On the contrary, when the abdominal pressure decreases, the male and female buttons engaged by the restoring force of the elastic body 23 are pulled in the direction of decreasing the size of the waist (FIG. 4A). In short, the optimum size is automatically adjusted according to the abdominal pressure.

  In the arrangement of FIG. 4, the male hook 10 is located on the outer side and the female hook 30 is located on the inner side as viewed from the wearer, but the opposite may be possible.

    In FIG. 1, the same effect can be obtained by replacing the male member 10 of the snap button with a female member and replacing the female member 30 of the snap button fixed to the spring with a male member.
