Japanese Patent No. 3220142

  The conventional wire tightening device has a complicated structure because the wedge-shaped body is assembled in the fixing position and the fixing release position in the body, which is not desirable in terms of workability and assemblability, and requires a special dedicated tool. To do.

  In addition, it is not desirable from the viewpoint of workability, for example, it takes time to complete the tightening because the wire is tightened with a dedicated tool after passing through the wire.

  Further, when the body is used as a means for bundling one continuous wire by bundling the wire and the wire ends, the bundling portion appears as a protruding protrusion that projects greatly outward. For this reason, when a single long wire bundled by a container is passed through, for example, a spiral hanger formed in a spiral tunnel shape, there is a problem such as being caught and deteriorating workability.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wire binding tool that can easily and quickly bind wires without using a dedicated tool, and that is compact and provides a reliable binding holding force.

In order to achieve the above object, according to the present invention, the vertical portion of the central portion and the lower end of the vertical portion are extended in the horizontal direction from left to right, and then along the center line in the order of the vertical direction and the horizontal direction. It is formed by a horizontal part and a vertical part that are bent along the longitudinal direction, alternately creating an upward open space and a downward open space, and ring-shaped closed space parts that are formed at the left and right ends thereof. It is characterized by being.

According to the wire binding device of the present invention , for example, when the wires and the ends of the wires are bound together, or when one end of the wire is formed in a ring shape and the terminal portion is fixedly supported along the wire, After passing the terminal part of one wire through one of the left and right closed spaces, pass through the front, rear, front, and rear of the vertical part without using tools etc. to the final closed space It can be passed through quickly like sewing.

  On the other hand, in the other wire, after passing through the terminal portion from the closed space side where the previous wire last passed, it is wound in a spiral shape in the order of downward open space, upward open space, and finally the previous wire The closed space where the wire first passes can be quickly wound spirally without using a tool or the like.

  As a result, it is possible to bind the wires without overhanging them, and to obtain a reliable and high binding holding force by acting so that the wire bites into each vertical portion against the pulling in the longitudinal direction. .

  Also, the vertical portion provided in the central portion can be wound around the vertical portion, one on the right-handed spiral and the other on the left-handed spiral, and the wire is S-twisted (left-handed), or A strong binding holding force can be obtained without being affected by the twisting direction of the Z twist (right-handed).

  First, the vertical portion, the horizontal portion, and the closed space portion are made of a single continuous wire that can be bent, so that the cost is reduced and a high bundling holding force is secured without greatly projecting outward.

  Second, the vertical part of the central part is shaped to be taller than the vertical parts on both sides. Alternatively, a protruding head that extends to the left and right is provided in the vertical portion of the central portion so that the wire applied to the vertical portion of the central portion does not easily come off from above.

  Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1 to 5.

  FIG. 1 shows a front view of a wire binding device according to the present invention.

The wire binding tool 1 is extended in the horizontal direction from the lower end of the vertical portion 3 to the left and right sides of the vertical portion 3 and then bent in the vertical direction and the horizontal direction to open the upward open space 5 and the downward opening. It consists of a horizontal portion 9 and a vertical portion 11 that are continuous along the longitudinal direction to alternately create the space 7, and a ring-shaped closed space portion 13 that is formed on both left and right ends of the space 7, and sandwiches the vertical portion 3 at the central portion. It has a symmetrical shape and is flexible enough to bend greatly.

  The vertical portion 11, the horizontal portion 9, and the closed space portion 13 are made of a bendable stainless steel material, and one continuous wire is used, and is formed by sequentially bending along the center line X.

  As a result, the material cost can be kept low, and processing can be easily and compactly made by bending.

  The vertical portion 3 in the central part is taller than the vertical portions 11 on both sides.

  The vertical portion 3 in the central portion has two functions. One is to prevent the spiral wire W-1 covering the vertical portion 3 from easily coming out from above as shown in FIG. .

  In this case, as shown in FIG. 3, by providing a protruding head 3a that extends to the left and right in the vertical portion 3, the protruding head 3a can more reliably prevent the wire W-1 from coming out from above. Is possible.

  The other is centered on the vertical portion 3 at the central portion as shown in FIG. 2 (arrow one-dot chain line), for example, a right-handed spiral on one side (left side in the figure) and a left-handed spiral on the other side (right side in the figure). Is to make each.

  This is related to the twist of the core wire constituting the wire, and there are S twist (left-handed) and Z twist (right-handed) in the wire. For example, when an S-twisted wire is wound around a left-handed spiral As a result of experiments, it was confirmed that the twisting and winding directions were synchronized, leading to a decrease in the binding holding power.

  In this case, a high binding retention force can be obtained by winding a right-handed spiral in the case of an S-twisted wire, and a left-handed spiral in the case of a Z-twisted wire. However, the present situation is that the twist cannot be directly seen from the outside by the coating.

  Therefore, when winding a wire in a spiral shape, a left-handed spiral region and a right-handed spiral region are created by sandwiching the central vertical portion 3 so that a spiral in a direction opposite to the twist of the wire is always ensured on one side. Thus, it is intended to always obtain a high binding holding force without being affected by the twist of the wire.

When the twist of the wire is known in advance at the construction site , for example, as shown in FIG. 6, the wire is bent along the center line X in the order of the horizontal direction, the vertical direction, the horizontal direction, and the vertical direction, and the upward open space The wire binding device 1 is used which includes a horizontal portion 19 and a vertical portion 21 that are continuous along the longitudinal direction, which alternately create 15 and a downward open space 17, and ring-shaped closed space portions 23 formed at both left and right ends thereof. It is also possible.

  In this case, a good high binding holding force can be obtained by changing the material and the wire diameter and increasing the number of the horizontal portions 9 and the vertical portions 11.

  In the wire binding tool 1 configured in this way, for example, when the ends of the wires W-1 and W-2 are bound together, the terminal portion of one wire W-2 is connected as shown by a chain line in FIG. For example, after passing through the closed space 13 on the right side, the vertical portions 11 are passed through the front surface, the rear surface, the front surface, the rear surface, and so on until the final closed space portion 13 that is the other side is sewn. At this time, it is possible to pass quickly without using a tool or the like.

  Next, after passing the terminal portion of the other wire W-1 from the closed space portion 13 (left side) through which the previous wire finally passed, for example, the downward open space 7 and the upward open space 5 are sequentially wound in the right direction. Winding in a spiral shape, and then winding in a left-handed spiral shape with the vertical portion 3 at the center as a boundary, a wire-to-wire bundling state is obtained. At this time, the wire W-1 can be quickly wound without using a tool or the like, and the wire W-1 applied to the vertical portion 3 in the central portion is not detached by the tall vertical portion 3.

  In addition, the winding direction of the wire W-1 can always be a right-handed region or a left-handed region with the vertical portion 3 at the center as a boundary for a wire whose twist direction is unknown.

  Therefore, the wires W-1 and W-2 act so as to bite into the vertical portions 11 with respect to the tensile load F · F1 in the longitudinal direction, thereby ensuring a reliable and high binding holding force. At this time, the wire binding tool 1 serving as a binding area does not protrude greatly outward.

  Therefore, as shown in FIG. 5, in the case of making a ring-shaped eye 25 (ring) at the end portion of the wire W-3, including the binding between the ends of the wire, the binding is performed in a compact, reliable and quick manner. It becomes possible to do.
