JP7271056B2 - Structure of eye splice of rope through which a flexible long object is inserted - Google Patents

Description

The present invention relates to a rope having a braided structure, in which a long object such as a flexible tube or a metal wire is inserted along the central axis of the rope, and an eye splice is formed at the end of the rope. It relates to the structure of

As a rope in which a long object is inserted along the central axis of the braided rope as described above, there is known a rope in which a metal wire is inserted, as disclosed in Japanese Patent Application Laid-Open No. 10-168772. Such ropes are used at both ends of the rope to communicate over the wire or to transmit power through the wire.

However, in such a rope, the periphery of the metal wire is covered with fibers, and when the rope is pulled under tension, the main body of the fiber rope is stretched, but the metal wire inserted through the center is stretched. In addition, since the periphery is covered with fibers and the frictional resistance is large, a large tension acts only on the metal wire, and the metal wire may break.

Therefore, when the tension is applied to the rope, the rope body and the metal wire can slide against each other without stretching only the rope body, as shown in FIG. A rope 1 is used in which a flexible plastic tube 3 is inserted along the central axis of a rope body 2 having a braided structure, and a metal wire 4 is inserted into the tube 3. - 特許庁

By doing so, since the inner surface of the plastic tube 3 is smooth, the tube 3 and the metal wire 4 can slide relatively easily, and when the rope 1 is tensioned, the rope body 2 can be pulled out. , only the tube 3 is stretched, the metal wire 4 is not stretched, and the metal wire 4 is not broken.

When a simple tension is applied to the rope 1, the metal wire 4 will not break, but when an ice splice is formed on the rope 1, there is a possibility that the metal wire 4 will break at the ice splice. occurs.

That is, when forming the eye splice 6 on the rope 1 as shown in FIG. 2 is bent into a loop, the tip of the rope body 2 is decomposed into each strand 5, and the decomposed strands 5 are inserted into the strands 5 of the rope body 2 after the tube 3 and the metal wire 4 are pulled out. Thus, the ice splice 6 is formed.

However, in such a structure, when the ice splice 6 is hooked on the support member and a large tension is applied to the rope 1, the strand 5 of the portion where the tube 3 and the metal wire 4 are pulled out strongly presses the tube 3, and the tube 3 is crushed. In this state, the rope body 2 is stretched while the tube 3 is locally pressed against the metal wire 4, and the metal wire 4 with a small elongation is stretched. It is not possible to follow the extension, and there is a possibility that it will break.

Also, along the central axis of the rope body 2 similar to that of FIG. 1, only a flexible plastic tube 3 is inserted, and air can be sent to a diver or the like through the tube 3. However, even in such a rope 1, an ice splice 6 is formed at the end thereof, and when a large tension acts on the rope 1, the tube 3 is crushed at the ice splice 6, and the diver It is also pointed out that it may not be possible to send enough air.

The front view which shows the state before forming an ice splice in this-application 2nd invention. The front view which shows the state which formed the ice splice in the rope of this-application 2nd invention.

The present invention will be described below with reference to the drawings. FIG. 3 shows the state before forming the ice splice 6 on the rope 1 of the first invention. The rope body 2 of the rope 1 is, as shown in FIG. 3 is inserted through, and a metal wire 4 is inserted through the tube 3 .

It should be noted that the rope body 2 in the present invention does not necessarily have to be an eight-strand cross rope. A structure such as two strokes may be used. Furthermore, it does not matter even if it is a twisted rope such as three-strike.

In the following description, a tube 3 is inserted along the central axis of the rope body 2, and a metal wire 4 is inserted in the tube 3. The metal wire 4 is inserted in the tube 3. It is not always necessary that the rope body 2 is lined up, and the present invention also includes a long object that is inserted along the central axis of the rope body 2 .

Reference numeral 7 denotes an eye splice rope, which is a short rope having the same braid structure as the rope body 2 of the rope 1 . An ice splice 6 is formed at one end of the ice splice rope 7 , and the other end of the ice splice rope 7 is disassembled into individual strands 5 .

Then, as shown in FIG. 4, the rope 1 and the ice splice rope 7 are assembled by inserting the disassembled strand 5 of the ice splice rope 7 between the strands 5 of the rope body 2 from the middle of the rope 1. I'm in.

FIG. 5 shows the rope 1 of the second invention before forming the eye splice 6. The rope body 2 of the rope 1 is the same as that of the first invention, and the rope body A flexible tube 3 is passed through along the central axis of 2, and a metal wire 4 is passed through the tube 3.

Reference numeral 8 denotes an eye splice rope, which is a short rope having the same braid structure as the rope body 2 of the rope 1 . Both ends of the eye splice rope 8 are separated into individual strands 5 .

Then, as shown in FIG. 6, the rope 1 and the ice splice rope 8 are inserted between the strands 5 of the rope body 2 from the middle of the rope 1 by disassembling the strands 5 at both ends of the ice splice rope 8. The ice splice 6 is formed by the intermediate portion of the ice splice rope.

According to the present invention, the disassembled strands 5 at the ends of the ropes 7 and 8 for ice splices are inserted between the strands 5 from the middle of the rope 1 to incorporate the ice splices 6 at the ends of the rope 1. It can be formed.

The end portion of the rope 1 protrudes from the connecting portion between the rope 1 and the ice splice ropes 7 and 8, the tube 3 and the metal wire 4 protrude from the end of the rope 1, and the metal wire 4 is used as a communication line as appropriate. , or as a power line, it can be used by connecting to where it is needed.

When the ice splices 6 of the ice splice ropes 7 and 8 are hooked on the support member and a large tension is applied to the rope 1, the tension acting on the ice splice ropes 7 and 8 is the same as that of the ice splice ropes. The ends of 7 and 8 are incorporated in the rope body 2 of the rope 1, and the tension acting on the eye splice 6 is transmitted to the rope 1 and acts thereon.

Therefore, the tension applied to the eye splice ropes 7 and 8 and the rope 1 does not act in such a direction as to press the tube 3 , and the tube 3 is not crushed and pressed against the metal wire 4 .

Therefore, even if the rope body 2 of the rope 1 expands and contracts due to the action of the tension, the metal wire 4 inserted into the rope body 2 can slide freely with respect to the rope body 2. Only the rope body 2 can be expanded and contracted independently of the metal wire 4 having poor stretchability, and the metal wire 4 is not forcibly stretched by the expansion of the rope body 2 and accidentally broken.

Therefore, according to the invention, the disassembled strands 5 at the ends of the eye splice ropes 7, 8 are incorporated into the rope body 2 of the rope 1 and are continuous with the rope 1, and the eye splice ropes 7, 8 There is no excessive tension applied to the rope 1 protruding from the time when the tube 8 is incorporated, and the tube 3 is not crushed by the tension and pressed against the metal wire 4, and the metal wire 4 is not excessively tensioned. There is no such thing as breaking due to the tension of .

As described above, when the metal wire 4 is not inserted into the tube 3, the tube 3 protrudes from a portion of the rope body 2 where the strands 5 are disassembled, and the tube 3 is used as an air supply pipe for divers and the like. can be used.

Even in this case, the tension acting on the eye splice ropes 7, 8 is such that the strands 5 separated at the ends of the eye splice ropes 7, 8 are incorporated into the rope body 2, and the tube 3 is tensioned. It cannot be crushed and the air supply to the diver is never interrupted.

Further, as shown in Japanese Patent Application Laid-Open No. 10-168772, the present invention can also be applied to the rope 1 having a structure in which only the metal wire 4 is inserted along the central axis of the rope body 2. and a large tension can be applied to the eye splice 6 without cutting the metal wire 4. - 特許庁
