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, in order to attach a cable to the floor, a ball is made at the bottom end of the cable to prevent it from being pulled out, or a retaining member is attached to the cable, which is then inserted into a split case mount so that it can be tensioned. However, processing is difficult,
It is extremely inconvenient to remove and install the cables, the length and tension of the cables cannot be adjusted, and if the cables become slack or loose, they must be replaced, which is inconvenient.

For this reason, recently there have been seen mounting fittings in which a sleeve is spring-loaded in a casing and can be fixed at any position on a long and narrow cable body using a ball held in the sleeve.

In this type of mounting bracket, the end of the wire fixed to the wire hangs as it is and becomes a hindrance, so it is cut off after setting.

[Problem that the invention attempts to solve]

However, with conventional hanging fittings, if the wire is too long, it will hang down or be exposed, which is unsightly, so it requires cutting the end, and if the wire becomes loose or loose. However, there is the inconvenience of having to cut off the end of the wire again, and if the hanging position of the item is changed, it is difficult to dispose of the wire hanging down, and if the end is cut off for aesthetic purposes, the hanging distance will be reduced. In any case, there was a problem that the end treatment of the cord body was difficult, such as not being able to respond to changes in the structure.

The present invention is an attempt to accurately eliminate these conventional drawbacks, and by equipping the cable tensioner with a storage guide for a winding mechanism that can handle the end of the cable, tensioning of any distance can be achieved. The purpose of the present invention is to provide a cable tensioning device that allows hanging, tensioning, and tensioning of a cable at a site extremely easily and quickly, and also enables attachment and detachment with a single touch, greatly improving work efficiency and providing a good appearance. That is.

[Means for solving problems]

In the present invention, a plurality of balls 3, 3 that are in contact with the tapered surface are loosely fitted into a hollow cylinder 2 having a tapered hole 1, and a cable body W inserted between the balls 3, 3 can be inserted into the hollow cylindrical body 2. A sleeve 5 having a hole 4 is slidably installed inside the sleeve 5, and one end of the sleeve 5 is arranged to protrude outside the hollow cylinder body by a spring 7 that always applies a biasing force in a certain direction to the sleeve 5. A guide 9 that can house and hold a take-up reel 8 that can wind up the end of the cable W inserted into the guide 9.
This is a cord tensioning device characterized by comprising:

〔Example〕

In the illustrated embodiment, a sleeve 5 fitted into a hollow cylindrical body 2 having a tapered hole 1 holds at least two or more balls, for example, three balls 3, 3, 3, so as to be able to come into contact with and separate from the sleeve 5. It is a pipe body having an insertion hole 4 so that the cable body W can be inserted from the outside in the axial direction between the balls, and has a cone portion 11 that fits into the tapered hole 1 of the hollow cylindrical body 2 approximately in the center. , three ball insertion holes 12 in the cone part 11
are provided, each holding a ball 3, and the end of the sleeve 5 on the open end 5' side is arranged to protrude from the hollow cylindrical body 2. The inner surface of the hollow cylindrical body 2 is the tapered surface of the tapered hole 1, which is the contact surface of the ball 3, and the ball 3 is on the open end 5' side of the hollow cylindrical body 2.
The distance between the balls 3, 3 is constrained to be smaller when the balls are near the opening than when they are far from the opening.

The sleeve 5 is constantly pushed by a spring 7 toward the opening on the tapered hole 1 side, and its opening end 5' is arranged to protrude outside the hollow cylindrical body. It is enclosed by a spring retainer 10 which also serves as a guide for a sleeve 5 which is detachably attached to or fixedly attached to the sleeve 2 . A guide 9 is provided in which a take-up reel 8 that is inserted into the sleeve 5 and can wind up the end portion of the cable body W protruding from the sleeve 5 is housed. For example, a guide 9 is formed by a U-shaped rib protruding from the side surface of a fixing plate 13 provided with a hollow cylinder 2, and the take-up reel 8 is fitted into the guide 9. Instead of the take-up reel, a take-up reel rotatably supported on a support shaft may be used, or the plate 13 may be omitted and a frame-shaped guide 9 or a guide pin provided directly on the outer periphery of the hollow cylindrical body 2. It can also be used to hold. In the reel 8 of this winding mechanism, a guide 9 may be provided with a mechanism for engaging and disengaging the cable W, such as a cutout groove or a cut so that the cable W can be easily pulled out and tensioned.

Further, the plate 13 is preferably fixed to the object using a mounting screw hole that can be fixed to a wall surface or a mounting surface part, a panel insertion hole 6, a rail fitting part, or a fixing means such as adhesive, for example, a shelf support for a glass case. used as

Therefore, when suspending an article using a wire or stretching a wire, press the sleeve 5 in the hollow cylinder 2 attached to the article or a wall to widen the distance between the balls 3, 3, and hold the hollow cylinder 2. Insert the cable body W from the open end 5' of the sleeve 5 protruding from the
The end portion is wound onto the reel 8 and the reel 8 is locked to the guide 9. When the pressure on the sleeve 5 is stopped, the cable body W is held between the balls 3 and fixed.

In addition, if there is slack in the tensioned state, the cable body W
By winding it into the winding mechanism, the slack can be taken up and the tension can be maintained.

When removing it, the sleeve 5 that is compressing the cable body W may be pushed into the hollow cylindrical body 2.

The rope body W attached at an arbitrary position in this way can be easily used to support an object.

In addition, when fixing the upper end of the cable body W to the ceiling,
It can be attached using a similar structure to the above-mentioned tension brace fixed to the floor surface, and it can also be used as a shelf holder in the middle or lower end of the cable body W to attach it to frames, panels, and other interior assembly structures. It is conveniently used for hanging or mounting.

[Effect of idea]

With this invention, when the cable body is attached to a mounting surface such as the floor at an arbitrary distance, the ends of the cable body can be easily processed, and the cable body can be attached and detached with one touch, so the installation and installation process is easy. Removal work is extremely simple and quick, greatly improving work efficiency.
It has good compatibility, and since the cable can be wound up, the length and tension can be adjusted over a wide range.The cable can be tensioned properly and safely, and it has a good appearance that does not spoil the beauty of the surrounding area. It can be used as a tension brace and can be applied to a wide range of different mounting area structures, so it has practical effects such as being highly versatile.
