DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A suspension device according to the present invention will be described below with reference to the drawings. 1 to 8 show a first embodiment of a suspension device according to the present invention. 1 and 2
Side view showing the use state of the suspension device according to the present embodiment,
3 to 8 show the hanging tool 5. Suspension device 1
Is a ball chain 2 in which a number of balls 4, 4,.
And a metal hanging tool 5 that is attached to the ball chain 2 so as to be movable and fixed. The ball chain 2 is suspended vertically via a joint 26 on a mounting hook 25 mounted on a wall surface 20 for mounting a suspension device.

The hanging tool 5 is formed by processing a single metal plate to form an upright wall 16 having an insertion portion 8, a hook portion 6 below the upright wall 16, and a ball engaging portion 11 above the upright wall 16.
The insertion part 8, the guide part 12 on the back side of the hook part 6, and the back part 15 in contact with the wall surface 20,
Are provided. The hook portion 6 is provided to extend upward from the lower portion of the upright wall 16 while being curved. The hook portion 11 is provided to extend from the upper portion of the upright wall 16 to the rear side. The rear portion 15 is provided to extend downward from the ball locking portion 11, and the guide portion 12 is formed by bending the lower portion of the rear portion 15 toward the hook portion 6. Suspended object 22
Is suspended from the hook 6.

The back surface 15 is a flat surface 1 in contact with a wall surface 20.
7, the guide portion 12 includes a lower wall 19 extending from the tip 17A of the flat surface 17 to the hook portion 6 side, and the lower wall 19
Has a passage hole 13 provided in the hole. The lower portion 2A of the ball chain 2 locked by the ball locking portion 11 is
It is movably inserted in the up-down direction through this passage hole 13 and is guided so as to maintain the hanging state. The insertion portion 8 has an insertion hole 9 through which the ball body 4 of the ball chain 2 can freely pass,
An insertion groove 10 is formed from the insertion hole 9 to the ball body locking portion 11 and through which the connecting cable 3 can pass. Insertion groove 1
0 has a width such that the connecting cord 3 can be inserted and the ball 4 cannot be inserted. The terminal end 10 </ b> A of the insertion groove 10 has a function as a contact wall for contacting the connecting cable 3 in the ball body locking portion 11.

When fixing the hanging tool 5 on the ball chain 2, the connecting cable 3 is passed through the insertion groove 10 as shown in FIG.
The ball body 4 is locked by the ball body locking portion 11 by being brought into contact with the terminal end 10A of the insertion groove 10. The connecting cable 3 has a terminal 10A
By this, the movement of the hanging tool 5 to the rear side is regulated and positioned. In addition, since the flat surface 17 of the back surface 15 is in contact with the wall surface 20, the rotation of the hanging tool 5 about the ball chain 2 can be prevented, and the hanging tool 5 is stably fixed on the ball chain 2.

The lower portion 2A of the ball chain 2 locked by the ball locking portion 11 is inserted through the passage hole 13 so as to be movable in the vertical direction. Thereby, the ball chain 2 can be maintained in the hanging state at the guide portion 12 on the back side of the hook portion 6, and the suspended object 22 can be stably suspended. Hanging equipment 5
When the player moves on the ball chain 2, the connecting cable 3 is moved from the ball body locking part 11 to the insertion part 8 while the hook part 6 is tilted in the direction of the arrow as shown in FIG. 2. The ball chain 2 located at the ball body engaging portion 11 moves to the insertion hole 9 through the insertion groove 10. When the insertion hole 9 passes through the ball body 4, the suspension tool 5 moves on the ball chain 2.

On the other hand, a reinforcing tongue for reinforcing the standing wall 16 is provided on the side of the standing wall 16. More specifically, a pair of reinforcing tongue pieces 14, 14 is provided on the side of the standing wall 16 near the insertion hole 9 to reinforce the standing wall 16 near the insertion hole 9. Such a reinforcing tongue piece can reinforce the standing wall 16 in the vicinity of the insertion hole 9 being reduced in area and disadvantageous in strength. A pair of reinforcing tongues 14A, 14A are also provided on both sides of the flat surface 17 from the lower wall 19 to the vicinity of the ball body locking portion 11, whereby the flat surface 17 is reinforced.

In the present embodiment, since the above-mentioned respective parts of the hanging tool 5 are all integrally formed by a metal plate, it is preferable because the manufacturing process can be simplified and the cost can be reduced. FIG. 9 is a side view showing a hanging tool according to the second embodiment of the present invention. The hanging device 5 has substantially the same configuration as the hanging device of the first embodiment, but the lower wall 19 has its tip 1
9A is bent upward, and the difference is that the tip 19A is close to the starting point 6A of the hook portion 6. With such a configuration, the lower wall 19 can support the hook portion 6 when a suspended object is hung on the hook portion 6, and can support a force that deforms the hook portion 6.

FIGS. 10 to 15 show a hanging tool 5 according to a third embodiment of the present invention. The hanging tool 5 includes an upright wall 16 having an insertion portion 8, a hook portion 6 extending from a lower portion of the upright wall 16 to the front side, a ball locking portion 11 extending from an upper portion of the upright wall 16 to the rear side, and a lower portion of the upright wall 16. And a guide portion 12 extending from the rear to the back side are integrally formed of resin. As in the above-described embodiment, the insertion portion 8 has the insertion hole 9.
And the guide groove 12 is also formed in the lower wall 19 extending from the lower part of the standing wall 16 to the rear side.
3 is formed by drilling. The insertion section 8 and the guide section 12 have the same functions as those in the above-described embodiment.

The hanging tool 5 according to the third embodiment has a lower wall 19, side walls 21, 21 and an upper wall 23. All of these walls are provided extending to the rear side of the standing wall 16,
Each wall is formed continuously and integrally. The above-mentioned ball body locking portion 11 is provided from the upper portion of the upright wall 16 to the upper wall 23. The rear wall 15 of the standing wall 16 has an upper wall 2
3, a side wall 21, and a hollow portion 24 that is surrounded by the lower wall 19 and that opens rearward. Upper wall 2
3, the back surface 23A of each of the side wall 21 and the lower wall 19,
21A and 19A continuously form one flat surface 17 and come into contact with the wall surface 20. Ball chain is hollow 24
And is inserted into the passage hole 13.

The method of moving and fixing the hanging tool 5 is the same as in the above-described embodiments. If the side walls 21 and 21 are pinched with fingers, the suspension and fixing of the hanging tool 5 on the ball chain can be easily performed. In addition, since the ball chain located behind the standing wall 16 is surrounded by the hollow portion 24, there is no danger that something will contact the ball chain from the side of the hanging device 5, and the hanging device 5 can be fixed stably. . Further, the hook 6
Are formed integrally with the lower wall 19,
9, the force for deforming the hook portion 6 is reduced.

Since the suspending tool 5 is formed integrally with the resin, it is possible to reduce the weight of the suspending device, mass-produce it, reduce the cost, and the like.

[0020]

According to the present invention, the hanging tool which can be fixedly moved on the ball chain can be easily and stably fixed on the ball chain, so that the hanging tool can be moved on the ball chain. It is easy to fix, and can be stably fixed on the ball chain. Further, cost reduction can be realized.
