On the other hand, a sliding member 2 which can slide up and down in the main body.
The insertion hole 10 through which the ball 18 of the ball chain 3 can be inserted into the body portion 9 is provided on the left and right sides. The insertion groove 11 through which the string 17 of the ball chain 3 can be inserted through the insertion hole 10 is formed in the sliding member 2. It is provided so as to open to the front. Body 9
A pair of elastic legs 12 having elasticity are provided on the lower surface of the
A locking projection 13 projecting outward is provided at the tip of the elastic leg piece 12, and is formed so as to be hooked on the locking portion 6 when the sliding body 2 is inserted into the main body 1. Also on the upper surface of the body portion 9 cavity 19 of box-type are provided, through holes balls 18 of the ball chain 3 on the wall back and forth in the cavity 19 can be inserted 14
A groove 15 is provided from one of the through holes 14 to the upper surface of the hollow portion 19 so that the string 17 of the ball chain 3 can be guided. A hook 16 on which the ball 18 of the ball chain 3 is hooked is provided. A ball chain 3 is connected to one end of the ball chain 3 in a state shown in FIG. 4, and a stopper such as a ring 25 is attached to the other end.

In the ball chain 3, the string body 17 is formed of a twisted yarn such as polyamide fiber or polyester fiber, and the ball 18 is preferably fixed to the string body 17 at a certain interval, at least at least the width of the fixture. . The ball 18 is formed of a synthetic resin such as polyamide, polyacetal, or polypropylene, and is formed into the cord body 17 by integral molding. Note that the ball chain 3 may be made of metal instead of synthetic resin.

The main body 1 and the sliding body 2 described above are formed by integral molding of a synthetic resin such as polyamide, polyacetal, or polypropylene, and the main body 1, the sliding body 2 and the ball chain 3 are combined to form a ball chain fixing device. To assemble, first, from the upper surface of the cylindrical main body 1, slide body 2
The elastic leg piece 12 is inserted, and the hollow portion 13 of the sliding body 2 is further inserted.
Is pressed, the locking projection 13 provided at the tip of the elastic leg piece 12 enters over the locking portion 6 of the main body 1 and the combination of the main body 1 and the sliding body 2 is completed. Thereafter, the sliding body 2 cannot be removed from the main body 1.

Although not shown, a guide groove is provided vertically on the inner wall on the rear side of the main body 1, and a guide projection is provided on the outer surface on the rear side of the body 9 of the sliding body 2. When the slide body 2 and the slide body 2 are fitted, the guide projection and the guide groove are fitted so that the slide body 2 cannot freely rotate with respect to the main body 1.

Next, the ball chain fixing device shown in FIGS. 5 and 6 differs from the embodiment shown in FIGS. 1 to 4 in that the ball 18 of the ball chain 3 installed in the main body 1 is inserted. The configuration is exactly the same except that the insertion hole 7 is of a large size and the insertion groove 8 for inserting the string 17 of the ball chain 3 is short.

The embodiment shown in FIG. 7 shows a modified example of the sliding body 2. A hook 16 provided at the upper part of the body 9 has a ball 18 of the ball chain 3 inserted into front and rear walls of a cavity 19. 1 except that one of the through holes 20 extends over the side wall of the hollow portion 19 and the groove 21 that can guide the cord 17 of the ball chain 3 is provided horizontally. It has the same form as the moving body 2.

The ball chain fixing device shown in FIGS. 8 and 9 is a fixing device in which a hook 16 is provided on the lower surface of the main body 1.
A box-shaped cavity 22 is provided on the lower surface of the main body 1,
A through hole 23 into which the ball 18 of the ball chain 3 can be inserted is provided on the front and rear walls of the second 2, and a groove 24 that can guide the cord 17 of the ball chain 3 from one side of the through hole 23 to the side wall of the hollow portion 22 is provided horizontally. On the other hand, this is a ball chain fixing tool in a form in which a hook is not provided on the upper surface of the body 9 of the sliding body 2.

Lastly, in the ball chain fixing device shown in FIG. 10, unlike the above embodiments, the insertion hole 7 into which the ball 18 of the ball chain 3 in the main body 1 can be inserted is also provided at the center of the front surface. Insertion grooves 8 through which the cords 17 of the ball chain 3 can be inserted are provided on both sides of the body 1 so as to extend along the side surface of the main body 1. At the end of the insertion grooves 8, insertion holes 7 through which the balls 18 can be inserted left and right are provided. . And sliding body 2
Hole 1 into which ball 18 of ball chain 3 can be inserted
0 is drilled from the front center to the center of the body portion 9, and insertion grooves 11 communicating with the insertion holes 10 and allowing the cord bodies 17 of the ball chain 3 to be inserted are continuously provided on both side surfaces of the insertion holes 10. The terminal end is orthogonal to the insertion hole 10, and an insertion hole 10 in which the ball chain 3 can be inserted and moved left and right is continuously provided in a T-shape.

[0020] The ball chain 3 is attached to the ball chain fixture.
When the ball chain 3 is inserted, it is a ball chain fixing tool that can be inserted even from the ball 18, and is a fixing tool suitable for mounting the ball chain 3 in which the arrangement interval of the balls 18 is narrow.

[0021]

The ball chain fixing device of the present invention has the configuration as described above, and the following effects can be obtained by this configuration.

The ball chain 3 in which the balls 18 are fixed to the string 17 at regular intervals, and the insertion holes 7 for the balls 18 are provided in the wall surface of the main body 1, and the insertion grooves 8 of the string 17 communicating with the insertion holes 7 are formed. A ball formed from a continuously provided main body 1 and a sliding body 2 provided with a ball insertion hole 10 in a body portion 9 of the sliding body 2 and an insertion groove 11 of a cord 17 communicating with the insertion hole 10. Since the chain fastener is a chain fastener, it is a stopper provided with a completely new stop mechanism that can securely fix the string without slipping of the string body 17 by the balls 18 arranged at regular intervals on the string body 17. In addition, for adjusting and fixing the ball chain 3, the ball chain 3 is easily and easily formed by forming the insertion holes 7, 10 and the insertion grooves 8, 11 having the unique form of the ball chain 3 in the main body 1 and the sliding body 2. There is an effect that the adjustment and the fixing operation can be performed smoothly.

An elastic leg piece 12 having a pressure contact slope 4 and a locking portion 6 provided on the inner wall of the main body 1 and a locking projection 13 provided below the sliding member 2 is opposed to each other. , The operation of pressing and releasing the sliding body 2 can be performed extremely smoothly, and once the main body 1 and the sliding body 2 are fitted, the sliding body 2 cannot be pulled out. Therefore, there is an effect that it is safe in use and can be used for a long time.

Outer bottom of body 1 or trunk 9 of slide 2
By providing the hook 16 of the ball chain 3 on the upper surface, the ball chain 3 can be easily formed into a loop shape and the length can be easily adjusted. is there.

Furthermore, since the main body 1, the sliding body 2, and the ball 18 are formed by integral molding of a synthetic resin, the effects of the present invention are very remarkable, for example, the fixture and the ball chain can be easily manufactured.
