Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized by connecting several pieces of kumiko with a shaft, and forming a nine-structure hour hand band with a chain for a bracelet, etc., or a two-piece O! It relates to rounded gold certificates that form O-connected items such as those with nine structures, such as those with a structure in which a case and a weight are connected via a shaft, and those with four honors.

Conventional chains use AGO muntins, and are constructed by fitting the ends of each muntin one after the other, and connecting each muntin by using a bottle in each hole provided in the fitted end. Or, since the positive and negative elements are connected using assembly parts for connecting wires, it is necessary to connect the muntins, which has the drawback of increasing costs.

The present invention is to eliminate the above-mentioned drawbacks and to provide a metal mt* which is made into a round shape and can be formed into a nine-structure uniform object by connecting the *aO fibers with a shaft. purpose.

The present invention, which achieves the above-mentioned objectives, will be explained below with reference to embodiments shown in the drawings.

In Figures 1 to 7, reference numeral 2 indicates the required aO muntin that constitutes the chain 1. ☆ A protrusion 2& is provided at one end of the muntin 20, and a recess 2b is formed at the other end. Each Kumiko 2
A shaft 3 is integrally formed on both sides of the convex portion 2a of each muntin 2, and a shaft 3 is formed on both protruding ends 4 forming the concave portion 2b of each muntin 2.
A hole 5 into which is fitted is formed. The convex part 210-3 of one muntin 2 is fitted into the hole 5 of the tip 4 of the muntin 2 that is 1nla connected to this, and the shaft 3 of the convex #2 & of this muntin 2 is fitted into the hole 5 of the protrusion #2 & of the next muntin 2. It is fitted into the hole 5 of the tip W4, and similarly each muntin 2
-3 and hole 5 are fitted to form chain l. Reference numeral 6.7 denotes connectors that extend over both ends of the chain l and are connected and disconnected from each other. One connection Jj4.6
A concave groove 8 is provided on the upper surface in a cross-sectional view, and the circular hole 5 formed in both sides of the concave groove 8 has an axis of the protrusion 2 & of the muntin 2 constituting one end of the chain l. J is fitted into the concave groove 8 of the ridge binding tool 6 *ii! Engagement holes 9'*9b are provided at predetermined intervals in the length direction, respectively.

In the example shown, there are three bonds each. The shaft 3 of the other fa connector 7 is connected to the tip s4 of the muntin 2 constituting the other end of the chain 10.
The holes 5Ki [are combined. On the opposite side 11 of the connecting device 7, there are two elastic arms 10IL that spring outward;
