Then, a wire is stretched or suspended, and an article such as a shelf board and other products is displayed on the wire.

[Problems to be solved by the device]

However, in this wire tensioning device, the holder main body accommodates a sliding sleeve in a hollow portion having upper and lower ends opened so as to be vertically movable, and can push and grip the wire from the upper end opening of the sleeve against the spring force. Therefore, the installation and removal of the wire is extremely easy, but to tension the wire, rope, string, wire, etc. between the ceiling and the floor, it is gripped in one direction by the spring force. In the direction, there is no gripping force, and it is a one-way chuck that can move the wire, so if you move multiple one-way chucks simultaneously in both directions, or if you move a long distance continuously in the grip direction, When a plurality of upholstery devices are used to hold a shelf, for example, in a suspended state, it can be moved freely in both directions in order to raise its horizontal position (chat to prevent the grip function from being used). So better to use in the open state) in the one direction to a handle on the convenient it would be grip,
The positioning is troublesome and inconvenient in handling, and there is a problem that the work is complicated.

The present invention is intended to solve this conventional problem, and it is possible to select whether or not to use the one-way chuck function, to easily attach it to a desired position and to suspend the article after hanging. It can easily cope with the change in the position of the resulting article, and the work of hanging, stretching, and tensioning the wire can be performed extremely easily and quickly, and the handling workability can be greatly improved, and the tension can be maintained safely. It is an object to provide a wire stretching device.

[Means for solving the problem]

According to the present invention, a hollow cylindrical sleeve into which a wire can be inserted, a holder in which a ball that inserts into the sleeve is restrained or free, and a ball that is pressed against a tapered surface formed in the holder. A wire grip body composed of a spring member for urging the sleeve, a threaded portion is provided on the outer periphery of the distal end of the sleeve, a threaded portion screwed into the threaded portion, a wire insertion hole, and a flange at the lower end. The operation pin having a portion is screwed into the threaded portion of the sleeve and is fixed in the tubular retainer so that the flange portion of the operation pin moves up and down between the upper end of the holder and the upper wall of the retainer. The wire tensioning device is characterized in that the retainer is slidably mounted together with a spring member in a hollow casing so as to be movable.

[Action]

In the wire tensioning device according to the present invention, the wire is inserted into the sleeve of the wire grip body through the insertion hole of the operating body, or the sleeve is inserted against the spring force to position the ball on the large diameter side of the tapered surface portion, Wires can be inserted between the balls as positions where the mutual spacing can be expanded. After that, when the pushing down of the sleeve is stopped, the sleeve moves relatively to the holder body toward the small diameter side of the tapered surface portion, and the ball is pushed out into the insertion hole by the tapered surface portion to clamp the wire and to stretch the wire. The wire can be installed or the wire can be removed from the wire grip body in the reverse order.

In addition, in order to prevent the grip function from being impaired, move the operation pin connected and connected on the sleeve and move the position of the flange part up and down between the upper end of the holder and the upper wall of the retainer. . That is, when the operation pin is turned to move the sleeve away from the tapered surface (Fig. 2), the ball is always in a free state and does not have a one-way chuck function, and the operation pin is turned in the opposite direction to pull the sleeve into the tapered surface. In the state (FIG. 1), the one-way chuck function is activated and the operating body is further fixed to the body. Furthermore, if the flange of the operating body is moved to the intermediate position, it will function like a one-way chuck. If the operating body is pushed in in the grip state (Fig. 3), the ball will be in a free state, and if released, it will return to the grip state. become. Moreover, when the wire W is gripped by the sleeve 1 and tension is applied to the wire W, or when the screw portion 13 of the casing 8 is screwed into a fixed portion such as a floor or a case, the spring member 9 that biases the retainer 7 is generated. Since it is compressed, the retainer 7 and the lid member 12 are separated from each other, and the retainer 7 can receive the force corresponding to the amount of compression of the spring member 9 via the thrust bearing 11 (FIG. 4). Further, the retainer 7 including the holder 3 can freely rotate in the casing 8 so that the wire W is not twisted when screwed.
