Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to wires, ropes, and other cording bodies for displaying displays, frames, lights, and other interior structures in stores, homes, exhibition halls, etc. The present invention relates to a tensioning device.

[Conventional technology]

Generally, when fixing wires to ceilings, floors, or walls, it is common to hang or tie them to the wall using hooks or perforated brackets, but this method requires extremely troublesome operations to attach and remove the wires. It is time consuming and has poor workability.

[Problem that the invention attempts to solve]

Conventionally, when installing a cable from the ceiling, it is not only difficult to fix the end of the cable, but also difficult to adjust the length and tension, which not only makes handling complicated, but also affects the aesthetic appearance of the surrounding area. There was also a problem above.

In particular, when exhibiting various items using these wires as a support, the load must be applied and the installation must be quite strong, and if a structure and installation form to prevent slipping and falling off is adopted, it will be complicated and the installation location will be difficult. This was a problem in terms of handling as it was extremely troublesome to make changes and replace the cables.

The present invention accurately eliminates these conventional problems and allows hanging, tensioning, and tensioning of cables such as wires to be carried out extremely easily and quickly, greatly improving work efficiency, and providing a good-looking product. The object of the present invention is to provide a wire tensioning device that is easy to handle and allows for easy adjustment of the setting position of exhibits.

[Means for solving the problem] The present invention has a threaded portion 8 on one end side and a hollow portion 2 at the other end of the pipe-shaped wall mounting body 1.
A cap 7 having a central hole with a tapered contact surface 7'' and a flange 7' is removably connected to the cap 7.
A floating body 5 provided with an insertion hole 4 through which the cable body W can be inserted into the hollow portion 2 of the wall mounting portion 1 is biased by a spring 6 and disposed so as to be slidable in the axial direction. A ball 3 is provided on the floating body 5 so that the cable body W can be attached and detached by protruding inward and retracted. This wire tensioning tool is characterized by being equipped with a stick 9.

〔Example〕

In the illustrated example, a pipe-shaped wall mount 1 with a hollow part 2 of a through hole is used by being buried in a ceiling surface, and a cable body W is axially inserted into the hollow part 2 of the wall mount 1. A floating body 5 having an insertion hole 4 through which it can be inserted is housed so as to be freely slidable in the axial direction. floating body 5
is formed by holding at least two or more balls 3 so as to be able to approach and separate in a direction perpendicular to the sliding direction, and has a taper that restricts the approach and separation of the balls 3 over the range where the cable body W is inserted and held between the balls. A shaped abutting surface 7'' is provided on the inner surface of the hollow portion 2 by the cap 7. floating body 5
The ball 3 is formed in the cone portion 13.
An insertion hole 10 is formed therein.

The floating body 5 is loaded in a direction in which the balls are always sandwiched between the balls by a spring 6, that is, in a direction in which the floating body 5 abuts against the contact surface portion 7'', and in this state, the lower end of the floating body 5 is in a space. It is formed to protrude.

Further, the wall mounting body 1 is provided with a threaded part 8 on the outer periphery of one end as a part for attaching and detaching to the wall, and a threaded hole 11 on the other end, and the threaded hole 11 has a central hole and a flange part 7'. A cap 7 is removably screwed into the cap 7, and a tapered contact surface 7'' for bringing the ball 3 into contact with and separating the ball 3 is formed in the center hole of the cap 7;
Moreover, a fastener 9 is screwed into the threaded portion 8 of the wall mounting body 1.

Therefore, when suspending or stretching a wire between the ceiling and the floor, attach the wall mount 1 with the flange 7' of the cap 7 facing the ceiling, and insert the wall mount 1 through the ceiling hole. , screw the screw part 8 into the screw hole on the ceiling side or insert it into the through hole and fix it with the fastener 9, and push the open end of the floating body 5 protruding from the wall mounting body 1 to attach the cable body W. When inserted into the insertion hole 4 along the axial direction, since the spaces between the balls are widened, the cable body W is pushed and inserted between the balls and is held between them. Thus, when this cable body W is pulled back, the floating body 5 together with the ball 3 is restricted by the conical ball contact surface with a narrow opening end 5' side, and the force to pull out the cable body W is exerted by the wedge action that narrows the distance between the balls 3. The rope body W can be stretched with strong resistance against
Due to its weight, it can be firmly tightened at all times and can be locked to prevent it from being pulled out.
In this case, the balls 3, 3, 3 can be reliably attached to the cable body W at any position, since they can strongly resist the torque that causes them to rotate around the line connecting the centers of the balls 3, 3, 3.

On the other hand, when removing the cable body W, it can be easily removed by pushing the floating body 5 against the spring 6 and pulling out the cable body W while the distance between the balls 3 is widened.

The cable body W attached at an arbitrary position in this manner can be easily used to support objects, such as placing a shelf board or hanging an object. In addition, when fixing the lower end of the cable body W to the floor surface, it is sufficient to attach it using a wire tensioning device having the same structure as the wire tensioning device fixed to the ceiling. It is also convenient to insert it and use it as a receiver for hanging or placing frames, panels, and other interior assembly structures.

[Effect of idea]

This invention has a threaded part on one end and a hollow pipe-shaped wall mount, and the other end of the cap has a central hole with a tapered abutment surface and a flange, which is detachably connected to the cap. A floating body provided with an insertion hole through which the cable can be inserted into the hollow part of the wall mounting part is biased by a spring and is slidably disposed in the axial direction, and protrudes into the insertion hole. A ball is provided on the movable body to which the cable body can be attached and detached, and a ball is provided on the movable body so as to be able to freely approach and separate from the contact surface part, and a tightener is attached to the threaded part of the wall mounting body, so that the cable body can be attached to and detached from the ceiling. Since it can be easily attached and detached from any mounting position on walls such as The deflection can be easily adjusted, and the end of the cable can be processed on the back side of the wall for a good appearance.The length and tension can be adjusted over a wide range, making it possible to tension the cable properly and safely. The wire tensioning device has a good appearance without impairing its aesthetic appearance, and it has a form that can be applied to a wide range of different wall structures, so it has practical effects such as being highly versatile.
