SOLUTION: A connection piece 10 is provided with a ball-like body part 12 formed at a center part, and foot parts 14 projecting on the same plane with angular intervals of 120 deg., a screw-like swollen part 16 is provided on a tip part of the foot parts 14, and these are integratedly formed with resin or metal. In the connecting method of the connection piece 10 to a ball chain 20, a through hole 24 in a ball 22 is expanded by the swollen part 16, and pressed in, and the swollen part 16 is screwed into the through hole 24 making use of the screw-like swollen part 16. Each ball chain 20 is fitted to each foot part 14 of the connection piece 10 in a repeated manner to form a honeycomb- like pattern. The decoration by the ball chain easy in connection and having two-dimensional expansion, and the three-dimensional connection easy to form the connection body can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball chain connector for connecting ball chains to each other.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Laid-Open Publication No. 6-28388 and Japanese Utility Model Publication No. 5-38271, a ball chain connecting tool for hanging a plurality of ball chains in parallel is known. This was intended to improve strength and the like.

[0003] The ball chain connecting tool is formed by connecting the ball chains in such a manner that the ball chains extend in the same direction from the connecting portion so that the ball chains are arranged side by side.
It was attached to various kinds of articles, such as a slider for a slide fastener.

[0004]

The above-mentioned ball chain connecting device of the prior art does not connect a plurality of ball chains in different directions, but connects a plurality of ball chains in the same direction at the same connecting portion. However, the ball chains are not connected to each other with a wide space.

The present invention has been made in view of the above-mentioned problems of the prior art, and has a ball chain connection in which a large number of ball chains are connected at a predetermined angle to obtain a connected body having a spatial expansion. The purpose is to provide tools.

[0006]

SUMMARY OF THE INVENTION The present invention comprises a plurality of feet and an enlarged section formed at the tip of the feet, and the enlarged section engages a hole formed in a ball of a ball chain. It is a ball chain connector.

The foot portion protrudes radially from the central portion at an equal angle to each other, and is formed integrally with the enlarged portion from resin or the like.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show a first embodiment of the present invention. In a ball chain connecting device 10 of this embodiment, a ball-shaped main body 12 formed at a central portion, 120 on the same plane
Projected feet 14 are formed at intervals of °. An enlarged portion 16 formed in a screw shape is provided at the tip of the foot portion 14. The main body 12, the foot 14, and the expanding portion 16 are integrally provided by resin or metal.

[0009] The ball chain connector 10 of this embodiment.
2 and 3, the ball 22 of the ball chain 20 and the foot 14 are directly connected to each other. The enlarged portion 16 is engaged with one of a pair of through-holes 24 provided in a straight line in the center of the ball 22 so that the ball 22 and the foot 14 face each other. 22 are larger than the through holes 24. In the ball chain 20, the balls 22 and the bar-shaped connecting members 26 are alternately connected, and the feet 14 of the other ball chain connecting portions 10 are connected to the balls 22 at regular intervals.

The method of connecting the ball chain connecting tool 10 and the ball chain 20 is as follows. The through hole 24 of the ball 22 is expanded and pushed in by the enlarged portion 16 of the foot portion 14, or the threaded enlarged portion 16 is utilized. , Are connected by screwing the enlarged portion 16 into the through hole 24.

The ball chains 20 are attached to the legs 14 of the ball chain connector 10 and connected so as to be repeated. In this embodiment, a honeycomb-shaped pattern as shown in FIG. 3 is formed. It is formed.

The ball chain connector 1 of the embodiment
The reference numeral 0 indicates that the connection operation is easy, and decoration with a ball chain having a two-dimensional spread and a connection body can be easily formed. Further, a connection having a three-dimensional spread is also possible. The connecting portion is detachable and can be adjusted to an appropriate size.

Next, a second embodiment of the present invention will be described with reference to FIGS. Here, the same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. The ball chain connecting device 30 of this embodiment is similar to that of FIG.
As shown in FIG. 5, the feet 14 are formed on the same plane of the central body 12 at 90 ° intervals from the center. The main body 12, the foot 14, and the expanding portion 16 are integrally formed of resin. The enlarged part 16 of this embodiment
Has a shape in which the tip of the foot portion 14 is flat and bulged into a spherical shape.

The ball chain connector 10 of this embodiment
Is also the same as the method of attaching each foot 14 of the ball chain connector 10 of the first embodiment to the ball chain 20. In this embodiment, a mesh-like pattern constituted by a square is formed. You.

The shape of the foot portion and the enlarged portion of the ball chain can be appropriately set, and the number of the foot portions and the protruding angle can be arbitrarily set. Therefore, by protruding the feet three-dimensionally, it is possible to form a ball chain connecting body having a three-dimensional spread.

[0016]

According to the ball chain connecting device of the present invention, a ball chain can be easily connected to a desired shape, and a connecting portion of a decoration or a structure, a connecting member of a planar or three-dimensional ball chain can be formed. It can be easily formed.
