Description

[Detailed Description of the Invention] The present invention relates to a branch rope attaching/detaching device for longline continuous use, which is equipped with a stopper to stop the movement of the rope hook.

Traditionally, in tuna longline fishing, attaching and detaching branch lines to the main line requires the following steps:
A double wire receiving recess having a dogleg-shaped conductor part is formed at one end of the steel wire, which has a winding and bending in the middle to create a spring. Using an attachment/detachment tool in which the rope holding hook, which is held in the heavy wire receiving recess, is formed so that the opening faces toward the conductor section, one-touch attachment and detachment of branch ropes to and from the main rope can be carried out. This attachment/detachment tool is highly effective in fast and reliable attachment/detachment depending on the pulling speed.
For reasons unknown (cannot be confirmed because it occurs underwater) during fishing, the rope holding hook moves accidentally and opens the line receiving recess, causing the attachment/detachment tool to come off the main line, causing the branch line and fishhook to be separated. In order to prevent this, the fishing industry has considered making the steel wire that makes up the attachment and detachment device thicker and more elastic, but if the elasticity of the steel wire is made stronger, This makes it even more difficult to attach and detach the main rope, which is not easy to do even now, as it requires considerable force.Not only does this make it impossible to attach and detach the main line repeatedly and at the same speed as the drawing speed, but it also makes it impossible for workers to work due to injury to their hands and fingers. Oh, because of that, in the fishing industry,
There has been a strong demand for an attachment/detachment device that can be easily attached and detached and that will not come off naturally.

The present invention was devised to meet this demand. One end of the steel wire has a coiled bend in the middle to create a spring.
A double wire receiving recess having a dogleg-shaped conducting wire portion is formed, and the other end of the steel wire has an opening for a rope holding hook to be held in the double wire receiving recess. Furthermore, a stopper that engages with the tip of the conductor part is slidably fitted to the other steel wire, and this stopper is pressed toward the conductor part by a spring, and the attachment/detachment tool is attached. When hanging on the main rope, remove the stopper from the conductor section, release the rope holding hook, open the wire receiving recess and hang it on the main rope, and after hanging, return the rope holding hook and engage the stopper with the conducting wire section. By restraining the movement of the rope hook, the attachment/detachment device attached to the main rope will not come off the main rope unless the stopper is removed manually, so the elasticity of the attachment/detachment device is made weaker than before, making it easier to attach and detach. To provide a branch rope attaching/detaching device for continuous longline use that does not cause spontaneous detachment of the attaching/detaching device even if it is made easier.

Next, an example of the implementation of the branch line attaching/detaching device for long lines according to the present invention will be described below with reference to the drawings.

In each of the drawings, 1 and 1' are one and the other of steel wires formed with a winding 2 in the middle to act as a spring, and one of the wires 1 has a dogleg-shaped conducting wire portion 3 at the end. A double receiving recess 4 is formed, and a rope holding hook 5 to be held in the double wire receiving recess 4 is formed at the end of the other 1' so that its opening faces in the direction of the conducting wire part 3. It is.

Reference numeral 6 denotes a stopper for stopping the movement of the conductive wire portion 3, which is slidably fitted onto the other steel wire 1' and has a concave shape on the outside as shown in Figures 1 and 2, or a stopper as shown in Figure 3. A finger rest 7 with an uneven surface as shown in the figure is provided, and a detent 8 whose tip is inserted between the double wire receiving recesses 4 is provided on the inside to ensure that the stopper 6 engages with the tip of the conductor portion 3. It is.

Reference numeral 9 denotes a spring sandwiched between the stopper 6 fitted to the other side of the steel wire and the spring receiver 10, which presses the stopper 6 toward the conducting wire portion.

11 is a branch rope tied to the winding 2, and a fishhook (not shown in the drawing) is attached to the tip. 12 is the main line, and a detachable device is attached to it when it is fed out, and the detachable device is removed when it is pulled up. It is something.

Next, the function of the branch line attaching/detaching device for longline use according to the present invention will be explained.

To let out the main rope 12, hold the attaching/detaching tool and pull the stopper 6 with your thumb against the elasticity of the spring 10 in the direction shown by the arrow in Figure 1. Since the stopper 6 that was engaged with the tip comes off from the conductor part 3,
Accordingly, if one side of the steel wire 1 and the other side 1' are squeezed so that they approach each other, the steel wires 1 and 1' will change from the state shown in Figure 1 to the state shown in Figure 2 due to the deformation of the winding portion 2. At this time, the wire receiving recess 4 is guided by the conductor 3, and the wire receiving recess 4 is hung on the main rope 12, and by loosening the grip of the attachment/detachment tool, the steel wires 1 and 1' are removed. is from the state shown in Figure 2 of the drawing to the first
Returning to the state shown in the figure, the rope holding hook 5 presses the main rope 12 housed in the line receiving recess 4 from the side and securely fixes the attaching/detaching tool to the main rope 12. At this time, when you release your thumb from the stopper 6, , is restored by the elasticity of the stopper spring 9 and engages with the tip of the conducting wire portion 3 to stop the movement of the steel wires 1, 1', so no matter what force is applied to the attachment/detachment tool during fishing, The attachment/detachment tool comes off from the main line 12 and the branch line and fishing hook are no longer lost.

However, when pulling up the main rope 12, if the stopper 6 is removed as described above and force is applied to the steel wires 1, 1',
The attachment/detachment tool is easily removed because the rope holding hook 5 escapes and the wire receiving recess 4 is opened.

As mentioned above, in the branch rope attaching/detaching device for longline chains according to the present invention, when the stopper is removed from the conductor part against the elasticity of the spring and the attaching/detaching part is grasped, the steel wire is deformed and the wire receiving recess is opened. When you loosen your grip on the attachment/detachment tool, the steel wire returns and the wire receiving recess is closed by the rope holding hook, and when you release the stopper at the same time, the stopper engages with the conductor part by the force of the spring, immobilizing the steel wire. Therefore, the attaching/detaching device can be attached to and detached from the main line with a single touch, and can sufficiently handle high-speed main rope feeding and pulling. Since it will never come off unless it is removed, it eliminates the loss of branch lines during fishing trips, which occurred frequently due to detachment devices coming off, and prevents the loss of fishing gear and the decrease in the amount of fish caught.

In addition, since this attachment/detachment tool uses a stopper to prevent it from coming off, the elasticity of the steel wire can be made weaker than that of conventional products.Therefore, attachment/detachment operations can be performed more easily and quickly, making fishing work easier. This not only contributes to labor saving and efficiency, but also prevents the hands and fingers from hurting even when the device is attached and detached many times, which has a great effect on the safety of workers.
