BACKGROUND OF THE INVENTION
The present invention relates to a wire tension device used for tensioning a wire to display and display display racks, foreheads, lights, and other interior tools.
[0002]
[Prior art]
[0003]
Conventionally, when a wire is stretched, a wire tensioner having a wire gripper is often used. As shown in FIG. 3, the wire gripper 30 includes a substantially cylindrical sleeve 31 having a tapered cavity therein, and a grip mechanism 32 is accommodated in the sleeve 31. The grip mechanism 32 is formed in a tapered shape whose upper part is cylindrical and whose central part opens downward, and a through hole 32a through which the wire W is passed in the vertical direction is provided. The tapered portion is also provided with a plurality of through holes 32b in the horizontal direction, and balls 32c are accommodated in these through holes 32b.
[0004]
A spring 33 is disposed in contact with the rear portion of the grip mechanism 32, and a lower end portion of the spring 33 is supported by a spring stopper 34 fitted in the sleeve 31. The grip mechanism 32 is always urged upward in the sleeve 31 by the spring 33, and is stopped in a state where the outer tapered portion of the grip mechanism 32 is in contact with the tapered portion in the sleeve 31. . At this time, the ball 32c in the through hole 32b is pressed by the inner wall surface of the sleeve 31 and moves to the innermost side of the through hole 32b.
[0005]
The wire W is attached to the gripper 30 by inserting the wire W from the tip of the grip mechanism 32. The tip of the wire W hits the ball 32 c, but when the wire W is pushed in as it is, the grip mechanism 32 moves backward in the sleeve 31 against the urging force of the spring 33. When the grip mechanism 32 is retracted, a gap is formed between the outer wall surface of the grip mechanism 32 and the inner wall surface of the sleeve 31, and the ball 32c moves outside in the through hole 32b. For this reason, a gap through which the wire W passes is formed, and the tip of the wire W can enter to a position beyond the ball 32c.
[0006]
When the pushing of the wire W is stopped in this state, the grip mechanism 32 is urged upward in the sleeve 31 by the spring 33, so that the wire W is viewed from the side surface by the ball 32c pressed against the tapered inner wall surface of the sleeve 31. It will be pinched. When trying to pull out the wire W, the grip mechanism 32 tries to move further upward, so that the force with which the ball 32c clamps the wire W is increased, and the wire W is gripped with certainty. When pulling out the wire W, if the grip mechanism 32 is moved backward by pressing the sleeve 31, the holding force of the ball 32c is weakened and can be easily removed.
[0007]
When the wire gripper 30 is used as a tension device for the wire W, for example, as shown in FIG. 4A, a pedestal 35 is attached to the lower end portion of the wire gripper 30, and the wire gripper 30 is shown in FIG. As described above, the pedestal 35 is screwed to the wall, floor, ceiling, or the like, and the wire W is inserted from the tip of the wire gripper 30 to be fastened.
[0008]
[Problems to be solved by the invention]
In the case of the wire tension device as described above, there is a problem that the installation location is limited. For example, when you want to make an anchor strong or when you want to use a wire to be stretched through a pillar or wall, you need to use another wire tension device, which limits the range of use. It is inconvenient.
[0009]
An object of the present invention is to provide a wire tension device having a wide range of use.
[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention employs the following means.
The wire tension device according to claim 1 is a wire gripper in which a disc-like flange portion is provided at a lower end portion of a sleeve, a substantially cylindrical shape, an upper end portion being bent inward by a predetermined width, and an inner wall surface of the lower end portion. A thread groove is formed and the body partly covers the wire gripper, and is fitted on the outside of the wire gripper, and the lower surface thereof is in contact with the flange portion, and the upper surface is in contact with the upper end portion of the body. A coil spring on the outer wall surface and a screw thread to be screwed into the thread groove of the body, and a thread groove on the inner wall surface, and a connecting tool attached to the lower end of the body. It is characterized by.
[0011]
Since it is configured in this manner, first, a coil spring is fitted into the wire gripper, and then the body is covered and a connecting tool is screwed and attached to the lower end portion of the body to assemble the wire tension device. When using a wire tension device, attach a washer with a screw thread formed on the outer wall surface to the wall surface, floor, ceiling, etc. Screw in the connector. The wire W is inserted from the upper end portion of the wire gripper and pulled.
In this case, as the washer, for example, a wood screw having a through hole for a wood screw or a cylindrical one that is screwed into an anchor attached to a wall or a column can be used.
Note that a coupling tool may be first attached to a washer attached to a wall or the like, and a body incorporating a subsequent wire gripper may be fitted.
[0012]
According to a second aspect of the present invention, there is provided the wire tension device according to the first aspect of the present invention, wherein the coil tension device is disposed between the upper surface of the coil spring and the upper end of the body, or between the lower surface of the coil spring and the flange of the wire gripper, or both. A teflon ring is arranged.
[0013]
With this configuration, even if the body is rotated with respect to the wire gripper, or conversely, the wire gripper is rotated, the Teflon ring performs a slip action, so that the coil spring is not twisted.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the member which is the same as that of the member demonstrated in the term of the prior art, or an equivalent, and abbreviate | omits description.
