Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tightening tool used for, for example, pulling or lifting a long object to be tightened, such as an electric wire.

(Prior Art) Conventionally, with regard to the tightening means used for this type of work, a rope or the like is simply wrapped around an object to be tightened to tighten it, and then the rope or the like is pulled or lifted. The above-mentioned work was performed by connecting it to a means by means of a traction method or the like.

(Problems to be solved by the invention) However, since the conventional means described above involves simply wrapping a rope or the like as appropriate to bind the object, the reliability of securing the object to be secured is inevitably compromised. This left a problem with the safety of the tensioning or lifting work.

Therefore, in view of the above-mentioned conventional drawbacks, the present invention provides a tightening tool that can easily and reliably tighten and secure an object to be tightened, and can greatly improve the safety of work such as pulling or lifting an object to be tightened. The purpose is to provide the following.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a first tightening band having a desired length and a direction substantially orthogonal to the first tightening band. The first
It consists of two second tightening bands that are set longer than the first tightening band, and a hook engagement part provided at each end of the second tightening band, and the second tightening band is set to be longer than the first tightening band. The object of the present invention is that the second tightening band can be wound and bound in the lateral direction of the outer periphery of a long object to be tightened, and the second tightening band can be wound and tied so as to alternately cross the outer periphery of the object in the longitudinal direction. That is.

(Function) The first tightening band is wound and fixed around the outer periphery of the object to be tightened in the shorter direction, and the second tightening band is similarly wound and secured in the outer periphery of the object to be tightened in the longitudinal direction. When the hook is wound so that the hook engaging portions at both ends are aligned, and a tensioning or lifting means is engaged with this to start pulling or lifting, the tension or lifting force of the tensioning or lifting means is applied. Acting on the second tightening band wound along the outer circumference longitudinal direction of the object to be tightened, the second tightening band including the tying of the first tightening band to the object to be tightened
The tightening belt is tightly wound.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. ,3
The first tightening band 2 is made of cloth knitted into a fine mesh shape or made of metal and has a flat cross section. and,
The second tightening bands 3a and 3b are made of cloth or metal which are similarly knitted into a fine mesh shape, and are relatively long and have a flat cross section.
The respective proximal ends of the first tightening band 2 are firmly fixed to the substantially central part of the first tightening band 2 by means of sewing or the like so as to be substantially perpendicular to the first tightening band 2. Engagement ring portions 4, 4 as hook engagement portions are integrally formed at the respective end portions of the bands 3a, 3b.

A fixing fitting 5 is attached to one end 2a of the first tightening band 2, and the fixing fitting 5 is attached to the shaft portion 5a on one side of the main body of the first tightening band 2, as shown in FIG. One end 2a of the band 2 is wound and fixed,
The release part 5b on the other side is the other end 2 of the first tightening band 2.
b is configured to allow insertion from below to above, and furthermore, it is rotatably supported approximately in the center of the main body via a support shaft 5c, and is normally inserted through the release portion 5b by a spring 6. A fixing claw 7 elastically fixes the other end 2b of the first tightening band 2.
is provided.

The tightening device 1 of this example is constructed as described above, and when using it, first, as shown in FIG. While winding, the other end 2b is inserted from below to above into the open part 5b of the fixing metal fitting 5 attached to the one end 2a to strengthen the wound state, and the other end is fixed by the fixing claw 7. Fix 2b so that it does not fall out. After that, the second tightening belt 3a, 3
b is wound so as to alternately intersect with each other along the longitudinal outer periphery of the object W to be tightened, and the engagement rings 4, 4, which serve as hook engagement portions at each end thereof, are aligned.

In this state, the hook part F of the tensioning or lifting means is engaged with the engagement ring parts 4, 4 as the hook engagement parts to start tensioning or lifting. At the same time, the tension or lifting force of the tension or lifting means always acts on the second tightening bands 3a and 3b wound along the longitudinal direction of the outer circumference of the object W to be tightened, so that the object W to be tightened is sequentially moved. In the tightening state, the second tightening bands 3a and 3b, including the winding and knotting of the first tightening band 2, are tightly wound around the object W to be tightened, and in this state, tensioning or Lifting work is carried out.

Next, another example shown in FIGS. 4 and 5 will be explained. In this example, the first tightening band 2 in the previous example is configured as two, and the second tightening band 3a, 3b is configured as one. In this embodiment, engagement rings 4, 4 are formed as hook engagement parts at both ends of one second tightening band 3c, and a predetermined ring is formed approximately in the center of the second tightening band 3c. Two first tightening belts 2 spaced apart
a and 2b are fixed in the same manner as in the previous example, and a fixing metal fitting 5 is attached to one of the first tightening bands 2b,
The rest of the configuration is the same as the previous example, so its explanation will be omitted.

Therefore, in this example, the two first tightening bands 2a and 2b are wound around the outer periphery of the object W in the transverse direction to secure the end of one of the first tightening bands 2b. Fix it firmly in the same way as above using the metal fittings 5, and
In the second tightening band 3c of the book, each second
The tightening band 3c is wound along the longitudinal direction of the outer circumference of the object W to be tightened, and the remaining functions and effects are the same as those in the previous example, so explanation thereof will be omitted.

In both of the embodiments described above, the cross-sectional shapes of the first and second tightening bands 2, 2a, 2b, 3a, 3b, and 3c are not limited to those in the embodiments.

In addition, the first and second tightening bands 2, 2a, 2b,
Desired anti-slip means may be provided on the inner surfaces of 3a, 3b, and 3c, that is, the surfaces that come into contact with the object to be tightened.

(Effects) In the present invention, there is provided a first tightening band having a desired length, and a first tightening band extending integrally in a direction substantially perpendicular to the first tightening band at a predetermined interval. Consisting of two second tightening bands that are opposed to each other at a distance and are set longer than the first tightening bands, and hook engagement parts provided at the ends of the second tightening bands, The first tightening band can be wound and bundled in the lateral direction of the outer circumference of a relatively long object to be tightened, and the second
By configuring the tightening belt to be able to be wound and tied so as to alternately cross the longitudinal direction of the outer periphery of the object to be tightened, the tension or lifting force of the relatively long object to be tightened can be applied to the longitudinal direction of the outer periphery of the object to be tightened. Since the winding force can be applied as the winding force of the second tightening band wound so as to cross the direction, the object to be tightened can be easily and reliably tightened, and the object to be tightened can be pulled or lifted. It has the advantage of greatly improving the safety of work.
