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 perforated bracket, but this is not a simple method for attaching or removing the cable. It is extremely troublesome to operate, especially when there are wires between the ceiling and the floor.
When tensioning cables such as ropes, strings, and lines, it is difficult to secure both ends, adjust the length, and adjust the tension, making handling complicated and affecting the aesthetic appearance of the surrounding area. There was also a problem above.
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 an attachment point such as a wall surface, and the However, it was only equipped with rings and holes, so it was impossible to expect a secure fixation, and the aesthetic appearance was also poor.
This had become a problem.

The present invention accurately eliminates these conventional problems and makes it extremely easy and quick to attach the cable to the wall, hang it, stretch it, and tension it, and also allows for one-touch installation and removal, making it easy to work. The purpose of the present invention is to provide a cord tensioning device that can significantly improve the performance of the vehicle, is securely attached, and has a good appearance.

[Means for solving problems]

In the present invention, a plurality of balls 3, 3 are loosely fitted into a casing 2 having a tapered surface 14' on the inner peripheral surface, and are in contact with the tapered surface 14', and a spring 10 always applies a pressing force in a fixed direction. 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 such that one end of the sleeve 5 protrudes outside the casing; A cable cable is provided with a threaded member 11 having a locking step 13, and a wall mounting portion 1 having a locking portion 12 that engages with the locking step 13 is removably provided. It is a body tension brace.

〔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. A plurality of, for example, three, ball insertion holes 15 are provided on the circumferential surface of the cone portion, and these balls 3
are loosely fitted into each other, and are held in the cylindrical casing 2 so as to be freely movable in an axial direction perpendicular to the direction in which the balls 3, 3, 3 approach and separate, with the end 5' of the sleeve 5 protruding. ing.

The casing 2 is formed by threadingly connecting a threaded member 11 to a hollow cylindrical body, and the inner surface of the casing 2 has a tapered surface 1 at one end with a narrow opening toward the open end 2''.
4' and a screw 2' at the other end. This tapered surface 14' fits into the cone part 14 of the sleeve 5, so that when the balls 3 are near the open end 2'' side of the casing 2, the spacing between the balls is smaller than when they are far from this opening. The sleeve 5 is always urged by the spring 10 in a direction that reduces the distance between the balls 3, 3.
This spring 10 is arranged between the end of the threaded member 11 as a spring seat and the stepped part of the cone part 14, but it is also possible to attach a partition wall to the inner surface of the casing 2 as a spring seat or to provide a protruding partition wall. Alternatively, the inner surface may be stepped. The screwing member 11 is screwed onto the screw 2', and is screwed in such a manner that the locking part 12 of the wall mounting part 1 is held between the locking step part 13 and the end of the casing 2. .

In FIGS. 1 and 2, the wall mounting part 1 is a plate with both ends bent at right angles, and a through hole 12' between the sleeve 5 and the screwing member 11 is formed in the locking part 12, which is the opposing bent piece. It has a screw 20, a hole 20' for attaching a nail, etc. on the other side, and can be fixed to a wall surface with the screw 20.

In the example shown in FIG. 3, the portion of the wall mounting portion 1 where the mounting hole 20' is located is an L-shaped plate, which is convenient for mounting at a corner.

In addition, the outer diameter of the casing 2 is made up of a small diameter part and a large diameter part to form a locking stepped part on the outer periphery,
It is also possible to fit and place the casing 2 in the locking portion 12 along the axial direction of the casing 2 .

Therefore, in order to attach the tension brace to the wall, the wall mounting part 1 is fixed with screws 20, but the wall mounting part 1
and the casing 2 are connected by separating the screw member 11,
After inserting the casing 2 into the predetermined position, the locking part 1
2 until the screwing member 1 is held between the locking steps 13.
Although this is done by screwing the casing 2 to the wall mounting portion 1, the procedure for connecting the casing 2 to the wall mounting portion 1 can be arbitrarily selected, such as fixing it to a wall or attaching the cable body W to a tension brace.

In order to hold the cable W in the tension device, insert the cable W into the insertion hole 4 along the axial direction from one end of the sleeve 5 protruding from the casing 2, and the end of the cable W will ball up. The sleeve 5 is pushed up against the spring 10, and the distance between the balls is widened along the tapered surface 14' of the ball contact surface, and the rope body W is inserted and held between the balls. Thus, when this cable body W is pulled back, the balls 3, 3, 3 have a tapered surface 1 with a narrow opening end 2'' side.
4', the wedge action that narrows the distance between the balls makes it possible to firmly resist the force that pulls out the cable body W and tension the cable body W, and especially when hanging an article, due to its weight. It must be firmly tightened at all times and can be locked to prevent it from being pulled out.

In addition, when removing the cable body W, it can be easily removed by pushing the sleeve 5 against the spring 10 to widen the distance between the balls 3, 3, and then pulling out the cable body W.

The cable body W attached at any position in this way
It can be easily used to support things, such as placing shelves on it or hanging things.A specific example of its use is shown in Fig. 4.

In the figure, 21 is the one fixed to the side wall of the example in FIGS. 1 and 2, 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, and 23 is a It is a tension equipment fixed to a ceiling surface or a floor surface, and can also be attached to an article to suspend the article or suspend the cable body W from the article.

[Effect of idea]

The present invention is achieved by providing a threaded member having a locking step on the casing that grips the cable, and removably disposing a wall mounting portion having a locking portion that engages with the locking step. , the cable body can be easily attached to the ceiling or other wall surface at any position,
Moreover, since it can be attached and detached with a single touch, the attachment and detachment work is extremely simple and quick, greatly improving work efficiency, and compatibility is also good.Furthermore, the deflection of the cable body can be easily adjusted, making it easy to adjust the length and tension. It is possible to adjust the tension over a wide range of degrees, and the rope body 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, since the structure is such that it can be easily applied to a wall structure with a wall mounting portion, it has practical effects such as being highly versatile.
