  The subject of this invention is providing the fastener of the string member for jewelry which can respond | correspond with the elastic body of one type of internal diameter, when using the string member for jewelry of various outer diameters.

  In order to solve the above-described problem, the clasp for a string member for jewelry according to the present invention has a metal hollow cylindrical outer shell body with holes formed at both ends, and a through hole. A string member for clothing having an elastic body built in the outer shell body in communication with the hole portion of the outer shell body, and inserted through the hole portion of the outer shell body and the through hole of the elastic body In the clasp for a string member for clothing that holds the peripheral surface of the outer shell by the elastic force of the elastic body, a concave groove is formed on the outer peripheral surface of the outer shell so as to protrude inward of the outer shell. When the elastic body is pressed by the protruding portion of the groove, the inner diameter of the through hole of the elastic body of the portion pressed by the protruding portion is larger than the inner diameter of the through hole of the elastic body of the portion not pressed by the protruding portion. The structure is also narrowed.

  A plurality of the concave grooves may be formed, and the cross-sectional shape of the outer shell at the portion where the concave grooves are formed may be an ellipse.

  According to the clasp for the garment member of the present invention, the protruding portion of the concave groove formed in the outer shell body is pressed by the protruding portion by setting it to an appropriate height corresponding to the outer diameter of the garment string member. It is possible to make the inner diameter of the through hole of the elastic body of the portion to be slightly smaller than the outer diameter of the garment string member, and the garment string member can be tightened with an appropriate elastic force. Moreover, the frictional resistance between the string member for clothing and the elastic body can be adjusted by adjusting the area of the protruding portion that contacts the elastic body. Accordingly, it is possible to generate an appropriate frictional resistance between the garment string member and the elastic body. Therefore, when adjusting the length of the garment string member, an appropriate frictional force is applied to the fastener. The garment string member can be slid under force, and the garment string member can be held on the fastener at a desired position.

  In conventional fasteners, if the inner diameter of the elastic body relative to the outer diameter of the garment string member is too small, the result is that the garment string member is tightened too much, resulting in damage, deformation, and elasticity of the garment string member. If the elastic body wears due to body damage or strong frictional force and the inner diameter of the elastic body is too large relative to the outer diameter of the garment string member, the holding force of the fastener to the garment string member Although there were many problems that it was insufficient, according to the clasp of the string member for jewelry of the present invention, by adjusting the height of the protruding portion of the concave groove, the area of the protruding portion that contacts the elastic body, Since it is possible to generate an appropriate frictional resistance between the garment string member and the elastic body, it is possible to eliminate such problems of the conventional fasteners, and is easy to use and excellent in durability. Can provide. In addition, since a single type of elastic body can be used for the string members for various outer diameters, it is possible to reduce the assortment of elastic bodies used for the fasteners.

  FIG. 1 is a cross-sectional view of a fastener for a garment member according to Embodiment 1 of the present invention, and FIG. 4 is an explanatory diagram of a necklace in which the fastener of the present invention is used.

  The necklace 1 is attached to the neck ring 1, the clasp member 3 through which the cord member 3 is inserted, the round ring 7 attached to the outer surface of the clasp 5 by brazing or welding, and the round ring 7. The locking tool 9 which can be opened and closed and the plate 11 attached to one end of the string member 3 are provided, and the locking tool 9 is connected to the hole 13 of the plate 11 for use. In this necklace 1, the string member 3 is constituted by a chain, and the length of the string member 3 is adjusted by sliding the string member 3 in the direction of arrow a or b with respect to the fastener 5.

  The fastener 5 includes a metal hollow cylindrical outer shell 15 and a cylindrical elastic body 17 incorporated in the outer shell 15.

  As the outer shell 15, a noble metal such as gold, silver, or platinum or an alloy thereof, or a metal such as brass, titanium, or stainless steel is used. Holes 19 a and 19 b are formed at both ends of the outer shell 15. The diameters D1 of the holes 19a, 19b are large enough to allow the string member 3 to be inserted, and larger than the outer diameter D2 of the elastic body 17 so that the elastic body 17 does not come out of the holes 19a, 19b. It is a dimension.

  The elastic body 17 is formed of a material having elasticity such as natural rubber, synthetic rubber such as silicon rubber, and has a through hole 21 through which the string member 3 is inserted. An inner diameter D3 of the through hole 21 has a size that allows the string member 3 to be easily inserted. The elastic body 17 is built in the outer shell 3 in a state where the through hole 21 communicates with the holes 19 a and 19 b of the outer shell 3.

  A concave groove 24 is formed on the outer peripheral surface 23 of the outer shell 15 by processing such as drawing and rolling. The concave groove 24 is formed so as to protrude to the inside of the outer shell body 15, and the elastic body 17 is partially pressed by the protruding portion 26 of the concave groove 24. When the elastic body 17 is partially pressed by the protruding portion 26, the inner diameter D4 of the through-hole 21 of the elastic body 17 of the portion pressed by the protruding portion 26 is the portion not pressed by the protruding portion 26. It is narrower than the inner diameter D3 of the through hole 21 of the elastic body 17. The height of the protruding portion 26 of the concave groove 24 is determined so that the inner diameter D4 of the through hole is slightly smaller than the outer diameter of the string member 3. Further, the area (length) of the protruding portion 26 that contacts the elastic body 17 is determined to be an area where an appropriate frictional resistance is generated between the string member 3 and the elastic body 17.

  Accordingly, even when the string member 3 having various outer diameters (thicknesses) is used, the inner diameter D4 of the through hole 21 of the elastic body 17 in the portion pressed by the protruding portion 26 is set to the outer diameter of the string member 3. By determining the height of the protruding portion 26 so as to be slightly smaller than the elastic member 17 having the same inner diameter D3 of the through hole 21, it is appropriate between the string member 3 and the elastic member 17. When the length of the string member 3 is adjusted, the string member 3 can be slid under an appropriate frictional force with respect to the fastener 5, and the string member 3 can be slid. Can be held by the fastener 5 at a desired position.

  FIG. 2 is a cross-sectional view of a clasp for a string member for clothing according to a second embodiment of the present invention. In the fastener 5 according to the second embodiment, two concave grooves 24 are formed, and the elastic body 17 is pressed by the two protruding portions 26. Other configurations are the same as those of the first embodiment. In the fastener 5 of this example, the elastic body 17 is pressed by the two protruding portions 26, and the elastic body 17 is configured to hold the string member 3 at two positions. Can hold the string member 3 in a more stable state.

  FIG. 3 is a cross-sectional view of a clasp for a string member for clothing according to a third embodiment of the present invention. In the fastener 5 according to the third embodiment, the cross-sectional shape of the outer shell body 17 in the portion where the concave groove 24 is formed is formed in an elliptical shape, and the elastic body 17 pressed by the protruding portion 26 of the concave groove 24. The cross-sectional shape of this part is also an ellipse having a major axis D4a and a minor axis D4b. Other configurations are the same as those of the first embodiment. In the fastener 5 of this example, since the portion of the elastic body 17 pressed by the protruding portion 26 has an elliptical shape, when the string member 3 having a flat cross section is used, the width of the string member 3 is wide. By inserting the string member 3 through the fastener 5 so that the portion corresponds to the long diameter D4a, the string member 3 can be stably held by the fastener 5.
