Description

  The present invention relates to a metal hook having a male-female joint structure that is suitably fixed to a fabric made of a knitted material having a stitch having a predetermined roughness.

  Hooks with a male-female coupling structure are also used as means for engaging two fabrics (a fabric with a female hook attached and a fabric with a male hook attached) to each other, for example, at the front of the front body of clothing. Yes.

  Generally, a metal hook is connected to a male and a female by inserting a lever provided on the male hook into a recess provided on the female hook. In addition, the metal hook includes both a female hook and a male hook, each of which includes a member called a Hansha plate composed of a caulking convex portion and a circular substrate extending in a flange shape from the base end portion of the caulking convex portion. , The fabric to be fixed by crimping the Hansha plate to each hook base (female hook base with a recess for female hooks, male hook base with a genko for male hooks) Fixed to. In addition, in the metal hook, a snap fit at the time of male and female coupling is realized, and a male spring hook is held in the female hook recess to keep the male and female coupling state. A metal spring such as a two-spring type is provided.

  By the way, when the metal hook is fixed to the cloth, it sometimes rotates in the surface direction of the cloth. As a device for preventing such rotation, for example, there is a hook disclosed in Patent Document 1 below. The hook has a flange portion of a mounting member (hansha plate) that fits into a housing portion formed in the center of the back surface of the button cap body, and is a caulking formed on the outer peripheral edge of the button cap body housing portion. The part is caulked over substantially the entire surface by bending in the center direction, and a protrusion for preventing rotation is provided on the surface which is a surface in contact with the cloth of the caulking part. The protrusions are provided radially around a cylindrical member protruding substantially at the center of the mounting member. In addition, a recess corresponding to the protrusion is provided on the back surface of the caulking portion. According to this hook, the rotation of the hook can be prevented by the protrusion of the caulking portion biting into the dough.

  However, when such metal hooks are used for fabrics made of knitted materials such as knits, knitted fabrics, and jerseys, the knitted fabrics are relatively thick and easy to stretch, and each one is knitted with relatively thick wool yarn. In other words, the protrusions as described above cannot sufficiently prevent the rotation of the dough with respect to the surface direction. Further, the hook is mainly circular, and the edge of the hook may cut the fabric (yarn) due to the rotation of the hook. In a knitted fabric, when one yarn is cut, the yarn is unwound one after another. Due to such problems, conventional metal hooks are rarely used for knitted fabrics, and are disclosed mainly in the following Patent Document 2 (particularly, FIG. 5 of the document). A so-called American hook was used. As shown in FIG. 8, the American hook has a plurality of long caulking legs 101 protruding at equal intervals on the peripheral edge portion 100 a of the Hansha plate 100, and these caulking legs 101 are inserted into the fabric stitches. In this way, the hook is fixed to the fabric without cutting the yarn.

  However, until now, the American hooks as described above have been mostly used for garments made of knitted fabric, so the design of the garment to which the hooks and hooks are attached has been limited. For this reason, there has been a demand to use metal hooks such as two spring hooks for knitted fabrics when manufacturing clothing.

  Furthermore, in recent years, materials having various properties can be used for fabrics such as clothing. Some of them have higher elasticity than conventional fabrics, and ring springs to realize various variations of such highly stretchable fabrics while suppressing rotation after fixation. There is a demand to use metal hooks such as two springs.
