【発明の詳細な説明】
本発明はフツク金具の取付方に工夫を施しため
がねチエーンの新規の製造方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new method for manufacturing eyeglass chains by devising a method for attaching hook fittings.
以下、本発明の実施例を図面に依拠して説明す

ーズ３に於ける中心孔３′の切縁に係止し、仍つ
てビーズ３の抜落を阻止する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. After a large number of beads 3 are pierced through a chain 2 made up of a large number of small rings 1 joined together, one at both ends of the chain 2 is pierced. A connecting hole 5 with a large diameter is formed by punching the tip of a punch (not shown) into the outer half of the inner diameter hole 4 of the ring 1' to enlarge the outer half of the inner diameter hole 4. By forming 5, the connecting hole 5
Both hems 7, 7' of the outer frame 6 surrounding the outer frame 6 are engaged with the cutting edge of the center hole 3' of the outermost bead 3, thereby preventing the bead 3 from falling out.
次いで、上記の連結孔５に連結環８の一方辺を

を奏するものである。 That is, according to the manufacturing method of the present invention, even when a thin chain must be used because the center hole of the bead is small, the inner diameter hole of the small ring, which is a component of the chain, can be expanded with a punch as described above. This makes it possible to attach hook fittings. Therefore, this has the remarkable effect of allowing a thinner bead eyeglass chain to be made compared to the conventional one, and even when the inner diameter hole of the small ring is relatively large, it is not necessary to add the work of punching it out as described above. This has the advantage that the installation of the hook metal fittings is much easier than when it is not punched out, and furthermore, as in the embodiment, both hem portions 7, 7' of the outer frame 6 portion that have been punched out are widened.
The beads can be prevented from falling out, parts can be omitted, and the weight can be reduced.
