Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a tensioning device for cords for displaying displays, frames, lights, and other interior structures in stores, homes, exhibition halls, etc. It is.

[Conventional technology]

Generally, when fixing a cable to a ceiling, floor, or wall, it is common to hang or tie it to the wall using a hook or a perforated bracket, but this requires the installation and removal of the cable. This is extremely troublesome, especially when installing cables such as wires, ropes, strings, and wires between the ceiling and the floor. Not only is it difficult to secure both ends, but it is also difficult to adjust the length and adjust the tension. In addition to being difficult to handle, there were also problems with the aesthetic appearance of the surrounding area. In order to solve this problem, for example,
Metal fittings for holding the cable body as seen in Publication No. 14040 have been proposed.

[Problem that the invention attempts to solve]

However, although these conventional metal fittings are extremely convenient and efficient for holding cables together, little effort has been made to attach the metal fittings themselves to mounting rails such as walls. Even if they were, they only had a ring or a hole, so they could not be securely mounted, and they were also aesthetically unsatisfactory, which was a problem.

The present invention accurately eliminates these conventional problems and makes it extremely easy and quick to attach, hang, stretch, and tension the cable to the edge of a plate-like projecting wall or rail. The object of the present invention is to provide a cable tensioning device that can be attached, detached, and moved with a single touch, greatly improving workability, and that is securely fixed and has a good appearance.

[Means for solving problems]

In the present invention, a plurality of balls 3, 3 that come into contact with the tapered surface 14' are loosely fitted into a casing 2 having a tapered surface 14' on the inner peripheral surface, and a pressing force is always applied in a fixed direction by a spring 10. and a sleeve 5 having an insertion hole 4 through which the cable member W inserted between the balls 3 and 3 can be inserted is slidably installed inside the casing 2 so that one end of the sleeve 5 protrudes outside the casing; This is a cable tensioning device characterized in that a rail holding part 1 is provided at one end of the cable.

〔Example〕

In the illustrated example, the sleeve 5 is a cable member W.
It is a pipe body having an insertion hole 4 so that it can be inserted from the outside in the axial direction, a cone portion 14 is formed with a stepped portion approximately in the center, and the cone portion 14 communicates with the insertion hole 4, In addition, a plurality of ball insertion holes 15, for example, three ball insertion holes 15, are provided in the circumferential surface of the cone portion, and the balls 3 are loosely fitted into these holes, and the end portions 5' are inserted into the cylindrical casing 2. The balls 3, 3, 3 are held in a protruding state so as to be freely movable in an axial direction perpendicular to the direction in which the balls 3, 3, 3 approach and separate.

The inner surface of the casing 2 has a narrow tapered surface 14' on the open end 2'' side, and the cone portion 1 of the sleeve 5
4, and restrains the balls 3 so that when they are near the open end 2'' side of the casing 2, the distance between the balls is smaller than when they are far from the opening. The spring 10 is always biased in a direction to reduce the distance between the balls.The spring 10 is inserted between the spring seat 13 screwed onto the inner surface of the casing 2 and the stepped portion of the cone portion 14 via a spacer 13'. Although it is provided, it may be provided by using the rail holding part 1 described later, by providing a partition wall protruding from the inner surface of the casing 2, or by making the inner surface stepped.

Further, the casing 2 has a screw 2' on the inner surface of the end opposite to the side where the tapered surface 14' is provided. are each screwed on.

The rail clamping section 1 is a ball clamping mechanism of the cable body W that is replaced with a ball mechanism that clamps a plate-like material.An example of clamping the rail R will be described next.

The inner cylinder 32 provided in the casing 2 is a cylindrical body having a screw threadedly engaged with the screw 2' on its outer periphery, and is provided with an insertion groove 34' for the rail R at one end. The inner circumferential surface on this end side is a tapered surface 31' whose diameter gradually decreases toward the opening side. Furthermore, the floating body 35 provided in the inner cylinder 32 has a cone portion 31 at one end that fits into the tapered surface 31' of the inner cylinder 32.
The cone portion 31 has an insertion groove 34 for the rail R.
It is equipped with Ball holding holes communicating with the insertion groove 34 and opening on the outer periphery of the cone portion are provided facing each other, and the balls 9 are housed therein. The end of the cone part is housed in the inner cylinder 32 with the end protruding from the inner cylinder 32 and is biased by the spring 12 in a direction that reduces the gap between the balls 9, 9. spacer 1 between the stepped part of the cone part and
Deployed via 3″.

The rail R can be provided with grooves on both sides into which the balls 9 are slightly fitted. In addition, as a means for attaching it to the wall, as shown in Figure 3, there is a type that has an integrated part that is fixed to the wall with screws, nails, etc., or as shown in Figure 5, it is installed on the wall with a wall mounting plate interposed. It may be of a shape that

Therefore, in order to attach the tensioning device to the rail R, when the insertion grooves 34 and 34' are pushed into the rail R, the end of the rail hits the ball 9 and the floating body 35 is pushed into the casing 2 against the spring 12. The gap between the rare balls 9 is large, and the rail R is held between the balls.

To remove it from the rail R, the floating body 35 may be pushed in and removed, and when it is to be slid on the rail R, it may be pushed in a little to loosen the clamping force and then moved.

In addition, in order to make the tension brace hold the cable W, one end 5' of the sleeve 5 protruding from the casing 2 is required.
When the cable body W is inserted into the insertion hole 4 along the axial direction, the end of the cable body W hits the ball and pushes up the sleeve 5 against the spring 10, causing the ball contact surface to taper. The space between the balls 3, 3 is widened along the surface 14', and the cable member W is inserted and held between the balls. Thus, when this cable body W is pulled back, the sleeve 5 moves and the balls 3, 3, 3
are regulated by the narrow tapered surface 14', and the wedge action that narrows the distance between the balls strongly resists the force that pulls out the cable body W, allowing the cable body W to be tensioned, especially when suspending articles. Due to its weight, it is always firmly tightened and can be locked to prevent it from being pulled out. This effect also applies to the relationship between the rail R in the rail clamping part 1 and the rail clamping part 1.

In addition, when removing the cable body W, the sleeve 5
Push against the spring 10 to release the balls 3, 3, 3.
It can be easily removed by pulling out the cable body W while the distance between the cables is widened.

The cable body W attached to any position on the rail R in this way can be easily used to support things, such as placing a shelf board or hanging something, and is used for specific purposes. An example is shown in FIG.

In the figure, 21 is the device of the present invention fixed to a rail R provided on the ceiling surface, 22 is a tension brace that holds the cable body W and is equipped with a connection part for suspended articles such as a panel 27; 23 is a tension brace fixed to the floor.

Note that the rail clamping part 1 is for clamping rail-shaped objects, and is not limited to the rail R. It can also be attached to an article having a similar shape, such as a panel, to hang the article. , it is also possible to suspend the cable body W from the article.

[Effect of idea]

With this invention, the cable body can be easily attached to any position such as the end edge of a plate-shaped projecting wall or a rail using the rail clamping part while being sandwiched between the casing, and can be attached and detached with one touch, so that Installation and removal work is extremely simple and quick, work efficiency is greatly improved, and compatibility is good.Furthermore, the deflection of the cable body can be easily adjusted, and the length and tension can be adjusted over a wide range. The struts can be adjusted appropriately and safely, making it possible to create a good-looking tension brace that does not spoil the aesthetics of the surrounding area.Furthermore, it has a form that can be easily applied to wall structures, making it highly versatile and practical. There is an effect.
