A substantially thick cylindrical rubber pipe B having elasticity by a rubber material or the like is provided.
[0017]
The outer shell A is provided with a lower through hole 4 and an upper through hole 5 at opposite positions, and the rubber pipe B is thicker than the through holes 4 and 5 of the outer shell A and thinner than the inner diameter of the inner wall surface of the outer shell A. At the same time, both ends of the outer circumferential surface of the outer circumferential surface are in contact with the inner wall surface of the outer shell A.

The rubber pipe B itself is formed so as to be easily elastically deformed when the string / chain C is forcibly inserted into the through hole 10 of the rubber pipe B. As a result, the string to the through hole 10 of the rubber pipe B is formed.・ Forced insertion of the chains C can be performed without difficulty, and the strings and chains C themselves are damaged (for example, rubbed strongly) by the sliding operation while the elastic pressure of the rubber pipe B is received. The string / chains C are not damaged by the outer surface of the string / chains C, and the string / chains C are not cut by sliding against a strong compression resistance.
[0018]
In the figure, reference numeral 6 denotes an attachment portion that is fixed to the outer surface of the outer shell A and is formed so that one end of the string / chain C can be attached easily and reliably.

【The invention's effect】
Therefore, the manufacturing method of the fasteners such as the strings for chains and the chain according to claim 1 includes a plurality of protruding piece portions 1b arranged on the outer peripheral portion of the base piece portion 1a, and the plurality of protruding piece portions 1b. A first step of forming the outer shell substrate 1 having the arc-shaped hole edge 3 at the tip portion from a metal plate material by pressing, and the base piece 1a of the outer shell substrate 1 or In addition, a part of the base piece 1a, or the base ends of the base piece 1a and the plurality of projecting pieces 1b form a lower hemispherical portion having a substantially hemispherical shell shape by drawing the flange portion, and the remaining portions A second step of forming an upper cylindrical portion that is substantially cylindrical by drawing; a third step of drilling a lower through hole 4 in the center of the lower hemispherical portion; and elasticity that has been cut to a predetermined length in advance. A fourth step of installing a rubber pipe B in the lower hemisphere portion and the upper cylindrical portion; An upper hemispherical portion having a substantially hemispherical shell shape is formed by drawing the upper cylindrical portion, and an upper through hole 5 is formed at the hole edge 3 of each of the projecting piece portions 1b, so that the entire outer shell substrate 1 is substantially a hollow sphere. Since it includes a fifth step of forming the outer shell body A having a shape and a sixth step of plating at least the outer surface of the outer shell body A in which the rubber pipe B is installed, the rubber pipe into the outer shell body A Anyone can easily and quickly perform the interior work of B, and the manufacturing work of the stopper can be easily and efficiently performed. In particular, a substantially thick cylindrical rubber pipe B that is not easily affected by deterioration over time and has excellent durability can be easily installed in the outer shell A. As a result, the string is formed in the through hole 10 of the rubber pipe B. -The chain C can be elastically pressed stably and reliably, and a durable stopper capable of holding the string / chain C for a long time can be manufactured.
In addition, the manufacturing method is simple, has excellent durability, is suitable for mass production, and can provide a relatively inexpensive stopper.
[0024]
Further, according to the method of manufacturing a fastener for a garment string / chain or the like according to claim 2, the left and right joints of the plurality of adjacent projecting piece portions 1b are formed after the upper hemispherical portion having a substantially hemispherical shell shape is formed. Since the edges 2 are fixed to each other by brazing, the strength and appearance of the outer shell A itself are further improved.
[0025]
Furthermore, the fasteners of the garment strings and chains according to claim 3 include an outer shell A formed in a substantially hollow sphere shape, and a substantially thick wall having elasticity that is preliminarily installed in the outer shell A. The outer shell A is provided with a lower through hole 4 and an upper through hole 5 at opposite positions. The rubber pipe B is thicker than the through holes 4 and 5 of the outer shell A and is an outer shell. The inner wall surface of the outer wall A is formed so as to be narrower, and both end portions in the cylinder center direction on the outer peripheral surface are in contact with the inner wall surface of the outer shell A. Since the string / chains C can be elastically compressed and formed so as to be smaller than the through holes 4 and 5 and located substantially on the line connecting the pair of through holes 4 and 5, The elastic compression of the strings and chains C in the center is easy and uniform, and is stable. Lance with a good clamping pressure holding state so obtained over a long period.
In particular, the rubber pipe B is formed such that most of the outer peripheral surface portion thereof does not contact the inner wall surface of the outer shell body A and most of the upper and lower end surface portions thereof do not contact the inner wall surface of the outer shell body A. Therefore, when the string / chain C is forcibly inserted into the through hole 10 of the rubber pipe B, the rubber pipe B itself is easily elastically deformed. For example, the cross-sectional shape of the string / chain C is not good. Even if there is a rule or there is a relatively large unevenness in the longitudinal direction of the string / chain C, this can be held in a balanced manner and the sliding operation of the string / chain C with respect to the rubber pipe B can be carried out without difficulty. It becomes a stop that can be done. As a result, the forcible insertion operation of the string / chain C into the through hole 10 of the rubber pipe B can be performed without difficulty, and the string / chain C can be performed by the sliding operation while the elastic compression of the rubber pipe B is applied. Damage to itself (for example, damage to the outer surface of the string / chain C due to strong rubbing, cutting of the string / chain C itself due to sliding against strong pressure resistance, etc.) It will be a thing.
In addition, it is possible to provide a relatively inexpensive stopper with a simple configuration, excellent durability, suitable for mass production.
