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, lines, etc. between the ceiling and the floor, it is not only difficult to fix both ends, but also to adjust the length and tension. In addition to being complicated to handle, such as the degree of difficulty, 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 when it comes to holding cables together, little effort has been made to attach the metal fittings themselves to an attachment point such as a wall. However, since they only had rings and holes, they could not be securely mounted, and they were also aesthetically unsatisfactory, which was a problem.

The present invention accurately eliminates these conventional problems, allows the cable body to be attached to the wall, hanged, stretched, and tensioned extremely easily and quickly, and allows the cable body to be tensioned in any direction. The object of the present invention is to provide a cord tensioning device that can be attached and detached with a single touch, greatly improving work efficiency, and that is securely attached 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 are always pushed in a fixed direction by a spring 10 fixed at one end. A sleeve 5 to which pressure is applied and which has an insertion hole 4 through which the cable W inserted between the balls 3 and 3 can be inserted is slidably installed so that one end of the sleeve 5 protrudes outside the casing. , is a cable tensioning device characterized in that a wall mounting portion 1 is pivotally mounted to the casing 2 via a pivot shaft 7.

〔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 that open on the circumferential surface of the cone portion, and the balls 3 are loosely fitted into these, respectively, with the open ends 2'' of the holes protruding into the cylindrical casing 2. The balls 3, 3, 3 are held so as to be freely movable in an axial direction perpendicular to the direction in which they 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 the balls 3 are near the casing 2 on the opening end 2'' side, the distance between the balls is smaller than when they are far from the opening. The spring 10 always biases the balls in a direction that reduces the distance between the balls.
This spring 10 is arranged between the spring seat and the stepped part of the cone part 14 by using the end of a threaded member 6 (described later) as a spring seat. The inner surface may be 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, and the pivot shaft is At 7, a wall mounting portion 1 is pivotally connected.

The threaded member 6 is a cylindrical body having a thread on its outer circumferential surface,
One end is screwed into the screw 2', and the other end is pivotally connected to the wall mounting portion 1 by a pivot shaft 7.

In Figures 1 and 2, the wall mounting part 1 is a U-shaped plate, with bearings provided on two opposing faces to suspend a pivot shaft 7, and a fastener such as a screw or nail on the other face. 20
It has an insertion hole 20' and can be fixed to a wall surface with a locking tool 20.

Figure 3 shows a modification of the wall mounting part 1, in which the bracket 1' is erected and the insertion hole 20' is separated from the pivoting part between the wall mounting part 1 and the casing 2, so the wall mounting part 1 can be fixed to the wall. It does not get in the way of your work.

As shown in FIGS. 1 to 3, the casing 2 can take any position within a range of approximately 180 degrees on the same plane.

In FIG. 5, the casing 2 and the wall mounting portion 1 are connected via two orthogonal pivot shafts 7 and 16, so that the casing 2 can be oriented in any direction. That is, the casing 2 has two projecting plates facing each other at the end on the pivot side, and the pivot shaft 7 is suspended between the projecting plates.
It is pivotally connected to a pivot shaft 16 which is orthogonal to the pivot shaft 7. The pivot shaft 16 is suspended on a cylindrical wall having a bracket 1', which serves as a bearing, protruding from the wall mounting part 1. To make this possible, only the bearing portion is made to protrude. This cylindrical wall bracket 1' may be welded or integrally molded to the wall mounting portion 1, or may be rotatably mounted around the central axis of the cylindrical wall as a rotation axis.

In addition to the embodiments described above, it is also possible to connect the casing 2 directly to the pivot shaft 7. Also, depending on the positional relationship between the wall mounting part 1 and the pivot shafts 7 and 16, the wall mounting part 1 and the wall to which it is attached may be connected to the casing 2.
If it does not impede the rotation of the
It goes without saying that the example shown in FIG. 5 can be directed in almost any direction.

Therefore, in order to attach the tensioning equipment to the wall, the wall mounting part 1 is fixed with the locking tool 20, but the connection between the wall mounting part 1 and the casing 2 can be done before or after fixing to the wall. The mounting of the body W does not matter before or after the connection of the casing 2 to the wall mounting portion 1, and the procedure can be selected according to convenience.

In order to hold the cable body W between the tension devices, the cable body W is inserted into the insertion hole 4 along the axial direction from the open end 2'' of the sleeve 5 protruding from the casing 2, and the end of the cable body W is inserted into the insertion hole 4. When the part hits the ball, the spring 10
As a result, the sleeve 5 is pushed up against the force, and the distance between the balls is widened along the tapered surface 14' of the ball contact surface, and the cable body W is inserted and held between the balls. Thus, when this cable body W is pulled back, the balls 3, 3, 3 are regulated by the narrow tapered surface 14' on the open end 2'' side, and the wedge action that narrows the distance between the balls makes them strong against the force that pulls out the cable body W. In particular, when hanging an article, it is always firmly tightened due to its weight and can be locked so that it cannot be pulled out.In this case, the casing 2 Since the tensioning device W can take any posture within a predetermined range as necessary, the tensioning direction of the tensioning device W can be freely selected.

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 shown in Figures 3 and 5 fixed to the upper surface of a horizontal or sloped surface, and 22 is a book that holds the cable W and is equipped with a connecting part for hanging articles such as a panel 27. A tension brace similar to the present invention, 23 is a tension brace similar to the present invention fixed to the floor surface so as not to be displaceable. In addition to this, it is also possible to attach it to an article and suspend the article, or to suspend the cable body W from the article.

[Effect of idea]

With this invention, the cable body can be easily attached to a wall surface such as a ceiling in any position and in any direction, and can be attached and detached with one touch, making the attachment and detachment work extremely simple and quick, and the work efficiency is also improved. It has been greatly improved, has good compatibility, and the deflection of the cable body can be easily adjusted, and the length and tension can be adjusted over a wide range, allowing for accurate and safe adjustment of the cable body, and improving the beauty of the surrounding area. It can be made into a good-looking tension brace that does not damage the structure, and can also be easily applied to wall structures. It has practical effects such as being highly versatile because of its shape.
