Description

[Detailed description of the invention] [Industrial application field] The invention is used in stores, homes, exhibition halls, etc.
The present invention relates to a wire stretching device and a wire grip used when a display, a panel, a hanger, and other interior structures are suspended by wires.

[Conventional technology]

Recently, a wire grip is used in which a sleeve body holding a ball or a shoe and an insertion hole in the center is biased by a spring to be slidably accommodated in a holder body having a tapered surface portion in which one side has a small diameter. 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,
There was a problem that the positioning was troublesome, the handling was inconvenient, and the operation was 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. As described above, the wire grip body including the spring member for urging the sleeve is housed in the hollow casing together with the spacer for inserting the upper end of the sleeve, and the operation pin having the wire insertion hole and the flange portion at the lower end. The wire tensioning device is characterized in that it is slidably arranged on an operation nut screwed onto the upper end of the casing.

[Action]

The wire tensioning device of the present invention inserts the wire into the sleeve of the wire grip through the insertion hole of the operation pin or pushes the sleeve against the spring force to position the ball on the large diameter side of the taper surface portion, and the balls are separated from each other. Wires can be inserted between the balls as positions where the 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.

Moreover, in order to prevent the grip function from being deteriorated, the operation nut connected and connected on the casing is rotated to move the operation pin, and the position of the flange portion is pushed and changed into the casing. In other words, turn the operation nut and use the operation pin to move the sleeve farthest from the taper surface (3rd
(Fig.) The ball is always free and does not have a one-way chuck function. In addition, the operation nut is turned in the opposite direction and the flange of the operation pin is pressed against the upper end surface of the casing and the sleeve is pulled in the taper surface (Fig. 1). If so, the one-way chuck function works, and if the operation pin is pushed in in the grip state, the ball becomes free, and if released, it returns to the grip state.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. A hollow cylindrical sleeve 1 into which a wire W can be inserted, and a ball 2 that restrains or allows the wire W to be inserted into the sleeve 1.
And a holder 3 in which the ball 2 is installed,
Wire gripping body formed of a spring member 6 for biasing the sleeve 1 so as to press the tapered surface 3 ₁ formed within, are furnished to the hollow casing 7 together with spacers 5 for inserting the sleeve upper end with, certain operating pin 4 provided with a flange portion 8 in the wire insertion hole 4 ₁ and the lower end is slidably deployed wire Zhang appliances in operation nut 9 screwed to the upper end of the casing 7.

As the sleeve 1 has a cone portion with a ball insertion hole, the cone portion, deployed urged by the spring member 6 to the tapered surface 3 ₁ at the inner surface of the holder 3, the operation pin 4 abutting the sleeve 1 Is installed outside the casing 7,
The manipulation pin 4 also using a pipe body with a wire insertion hole 4 ₁ of the wire W, slidably inserted in the operating nut 9, and connected construction as the sleeve 1, the forward and backward relative to the casing 7 of the operation nut 9 It is variable in the axial direction. In the holder 3 of the wire gripping member, whereas the wire W of the ball 2 when the one in the hollow portion peripheral surface is made of those forming the tapered surface 3 ₁ whose diameter, the wire W is inserted into the sleeve 1 The wire W can be easily and freely slid in a state in which the sleeve 1 is firmly prevented from sliding down and the sleeve 1 is pushed against the spring member 6.

In the figure, 7 ₁ and 9 ₁ are screws, 10 is a spring seat, and 11 is a mounting seat.

[Effect of device]

According to the present invention, a wire grip body is housed in a hollow casing together with a spacer for inserting an upper end of a sleeve, and an operation pin having a wire insertion hole and a flange portion at a lower end is screwed to an upper end portion of the casing. Since the wire is slidably attached to the operation nut, the wire can be attached and detached with one touch, and the wire chucking function and the free state can be easily selected, and multiple unidirectional chucks can be moved in both directions at the same time, or gripped. It is possible to move a long distance continuously in any direction, and the handling on the wire can be performed extremely well, and since the wire can be reliably held in a tensioned state, the work can be extremely simple and quick. Also, it is possible to easily change the arrangement of the articles, easily attach and detach the exhibited articles to the wire during construction, and the configuration is simple. There is a practical effect of the equal is.
