Description

[Detailed Description of the Invention] The present invention relates to a three-strand rope with a wound string, which is formed by winding a string around the outer circumference of a three-strand rope.

An example of the use of such a three-strand rope with a winding string is a trunk rope used in crab cage fishing. Crab basket fishing is a method of fishing in which crabs are caught by hanging bait filled with bait at predetermined intervals from a sturdy three-strand trunk rope into the sea, then placing the baskets on the seabed. The main rope used in this fishing method is an extremely rigid, tightly twisted rope in order to pull up the basket vertically so that it does not drag on the seabed and overturn.

In addition, when the crab cage is tied directly to a tightly twisted trunk rope with a branch string, the branch string easily slides on the trunk rope, so the rope is wound around the trunk rope at predetermined intervals. A branch cord is tied around the rope. This winding string also serves as a guide for where to hang the crab cage on the trunk rope.
It prevents the trunk rope from rubbing against the branch cords and also serves as reinforcement for the trunk rope.

By the way, the method of winding a cord around such a three-strand rope is to secure one end of the cord between the strands of the three-strand rope, and then wrap the cord around the outer circumference of the three-strand rope. The method used is to twist the rope, then re-twist the other end of the rope and secure it by sandwiching it between the strands of the three-strand rope. When the end of the wound rope is sandwiched between the strands of the three-stranded rope, a wedge-shaped device called a spike is driven between the strands of the three-stranded rope to widen the spacing between the strands, and the end of the wound rope is inserted between the strands of the three-stranded rope. Insert and hold.

However, in the case of a tightly twisted, rigid three-stranded rope such as the main rope used in the crab basket fishing method, it is extremely difficult to spread the strands with a spike, and in actual work, it is difficult to wind the rope. Currently, most of the time required is spent typing spikes. Also, during this work, the spikes almost always damage the three-strand rope, resulting in a decrease in the strength of the three-strand rope.

The present invention has been developed in consideration of the above circumstances, and has a structure of a three-strand rope with a winding cord that allows the winding cord to be easily wound and prevents damage to the trunk rope during winding. The purpose is to provide the following.

Therefore, in the present invention, when manufacturing a rigid three-strand rope, fixed strings are inserted between the strands at predetermined intervals, and a wrapped string is connected to the fixed string at one end.
It is characterized in that it is wound around the outer periphery of the three-strand rope to a length of about 15 to 50 cm, and the other end of the wound string is firmly fastened to the three-strand rope.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a three-strand rope with a winding cord according to the present invention. 1 is a three-strand rope, and the three strands 2a, 2b, 2
c are tightly twisted together to form a tight twist. 3
is a fixed string inserted and fixed between the strands 2 of the three-stranded rope 1; one end of a winding string 4 is connected to the fixed string 3; It is wound around the outer periphery of the rope 1, and the other end is connected and fastened to a second fixed string 5 which is inserted between the strands 2 of the three-stranded rope 1 and fixed.

To show a more specific configuration of the three-stranded rope with a winding string in this example, the length of the three-stranded rope 1 is 600 m, the outer diameter is 28 mm, the rope pitch is 64 mm, and the rope lead (rope pitch/ Rope outer diameter) is 2.3. In addition, the outer diameter of strand 2 is 13.7 mm, and the strand pitch is 50 mm.
The strand lead (strand lead/rope outer diameter) is 1.82, making it an extremely highly twisted and rigid rope. On the other hand, the fixed string 3 is a flexible braided cord with 16 threads without a core and has a diameter of 6 mm, and is fixed to the three-strand rope 1 at intervals of 50 m.

FIG. 2 shows the fixed state of the three-strand rope 1 and the fixed string 3 or the second fixed string 5 in the above embodiment. The fixed string 3 is made by folding a single string in two to form strands 2a and 2b.
2c and fixed, forming a loop 6. The appropriate length of the loop 6 is about 2 to 4 cm. If this is too long or too short, it will be difficult to connect it to the winding string 4. Further, it is preferable that both end portions 7a and 7b of the fixed string 3 protrude from between the strands 2 by about 10 to 20 cm. If it is too long, it will get in the way, and if it is too short, there is a risk that the fixed string 3 may slip out from between the strands 2. Similarly to the fixed string 3, the second fixed string 5 is also fixed by being inserted into the three-strand rope 1.

FIG. 4 shows a state in which the winding string 4 is connected to the fixed string 3 shown in FIG. 2 and wound around the three-strand rope 1. The winding string 4 is a three-strand rope with an outer diameter of 10 mm, and one end thereof is connected to the fixed string 3.
The end portion 8 thereof extends along the three-strand rope 1 together with both end portions 7a and 7b of the fixed string 3. A string 4 is wound around the three-strand rope 1 from above the end 8 and both end portions 7a and 7b. The length of winding the cord 4 around the three-strand rope 1 is 15~
Approximately 50 cm is appropriate, and the length of the end 8 of the winding string 4 is preferably about 10 to 20 cm longer than the length at which the winding string 4 is wound around the three-strand rope 1.

The winding string 4 may be simply wrapped around the outer circumference of the three-strand rope 1, but in that case, the winding string 4
Since the three-strand rope 1 is likely to loosen and shift on the surface of the three-strand rope 1, it is preferable to adopt a winding structure as shown in FIG. That is, the winding string 4 hooked and connected to the loop 6 is first wound once around the outer periphery of the three-strand rope 1, and then hooked around the base of the loop 6 and wound in the opposite direction. Next, it is hooked onto the previous winding string 4 and wound in the forward direction, and then hooked onto the previous winding string 4 and wound again in the reverse direction. In this way, the thread is wound over a predetermined length while being hooked on the previous winding string 4 in turn and reversing the winding direction alternately.

Further, FIG. 6 shows a state in which the other end of the winding string 4 is fastened to the second fixed string 5. The end 8 of the winding string 4 is folded back to form a loop 9 near the second fixed string 5, and the winding string 4 is wound from above the folded end 10 to form a loop 9 at the folded end 11.
is pulled out from between the winding strings 4. Then, the tip of the winding string 4 is passed through the loop 6 of the second fixed string 5, wound once around the three-strand rope 1, and then the tip is passed through the loop 9. By pulling the folded tip 11, the loop 9 is pulled together with the tip of the winding string 4 between the three-strand rope 1 and the winding string 4 wound around its outer periphery, and is firmly fastened. be.

It is preferable that the fixed string 3 and the second fixed string 5 form a loop 6 as described above, but as shown in FIG. It may be simply inserted between the strands 2b and 2c. In this case, the winding start portion of the winding string 4 is tied and connected to the fixed string 3 at one end of the winding string 4, as shown in FIG. It is appropriate to tie the fixed string 3 and the winding string 4 with a true knot or a machine knot. The winding string 4 tied to the fixed string 3 is wound around the outer periphery of the three-strand rope 1, just as in the case of FIG.

In addition, when the second fixed string 5 is simply inserted between the strands 2 and fixed as shown in FIG. 3, the end of the winding of the winding string 4 is as shown in FIG. After being tied to the second fixed string 5 and wrapped once around the outer circumference of the three-strand rope 1, the loop 9
, and is firmly fastened by pulling the folded end 11.

In the present invention, the fixed string 3 and the second fixed string 5 are
They do not need to have the same structure; the fixing string 3 may have the structure shown in FIG. 2, and the second fixing string 5 may have the structure shown in FIG. 3, or vice versa. Further, the second fixed string 5 is not necessarily necessary, and it is sufficient if only the fixed string 3 is placed at the position where the winding string 4 starts winding.

FIG. 8 shows the structure of the winding end portion of the winding string 4 in the case where the second fixed string 5 is not provided. In other words, three twisted cords 4 are twisted into rope 1.
After wrapping the last time around the outer circumference of the
The end of the rope is passed through the loop 9 of the end 8, and the folded end 11 is pulled to create a three-strand rope 1.
By pulling in between the winding string 4 and the winding string 4, the winding string 4
The tip of the is firmly fastened.

According to the present invention, the fixed string 3 is made of three twisted ropes 1
Since it is sandwiched between the strands 2 of the three-strand rope 1 during manufacture, by connecting the wrapping string 4 to the fixing string 3, the wrapping string 4 can be easily fixed to the three-strand rope 1. You can wrap the string 4
The winding work becomes extremely easy. Furthermore, since the fixed strings 3 are inserted in advance at predetermined intervals, this serves as a guide for the position at which the winding string 4 is to be wound, and the winding string 4 can always be wound at an appropriate position. In addition, a second fixed string 5 is fixed to the three-strand rope 1, and the wrapped string 4
By connecting and fastening the end of the winding to the second fixing string 5, the winding string 4 can be fixed even more firmly.

In addition, instead of inserting the fixed string 3 between the strands 2 of the three-strand rope 1 in the present invention, it is also possible to insert the winding string 4 directly between the strands 2. However, in order to wrap the winding string 4 around the outer circumference of the three-strand rope 1 over a range of 15 to 50 cm, the winding string 4 needs to have a length of several meters. When inserted between the strands 2 during manufacturing, the part of the winding string 4 coming out of the three-strand rope 1 gets wedged between the twisted three-strand rope 1 and the voice that forms the three-strand rope 1. in,
It may break or damage the three-strand rope 1.

In the present invention, the fixed string 3 is also connected to the second fixed string 5.
The length of the part protruding from three-strand rope 1 is at most ten or so centimeters, and a relatively thin and flexible string can be used, so even if this is sandwiched between two strands, it will naturally form three-strands. It passes through the voice while being fitted into the groove between the strands 2 of the rope 1, and will not be cut or damage the three-strand rope 1.

The three-strand rope with a winding string of the present invention is not limited to use as a trunk rope in the crab cage fishing method described above, but can be widely used in three-strand ropes that require other winding strings to be wound. It is something that can be done.
