現が強く要望されていた。Traditionally, in tuna longline fishing, attaching and detaching branch lines to the main line requires the following steps:
A double gutter receiving recess with a dogleg-shaped guiding rope part is formed at one end of the steel wire, which is bent in the middle to create a spring, and the other end of the steel wire is provided with the By using the attachment/detachment tool, which has a rope holding hook that is held in the double gutter recess with its opening facing toward the guiding line, one-touch attachment and detachment of the branch line to the main line allows the longline to be fed out. Or, it has a great effect on fast and reliable attachment and detachment depending on the pulling speed, but the reason for this attachment and detachment device is unknown during fishing (cannot be confirmed because it occurs underwater)
However, in the fishing industry, there have been many accidents in which branch lines and fishing hooks have been lost due to the rope hook moving accidentally and opening the gutter receiver recess, causing the attaching/detaching tool to come off the main line, resulting in the loss of branch lines and fishing hooks. As a preventive measure, it was considered to make the steel wire that makes up the attachment/detachment device thicker and more elastic, but increasing the elasticity of the steel wire would require considerable force even at present, making attachment and detachment operations, which are not easy, even more difficult. This not only makes it impossible to attach and detach the main line in accordance with the speed at which it is fed out and pulled up, but also to put workers at risk of injuring their hands and fingers and being unable to work. There was a strong demand for an attachment/detachment device that would not come off naturally.

ものである。The present invention was devised to meet this demand, and consists of forming a double gutter receiving recess with a dogleg-shaped guide rope at one end of the steel wire, and at the other end, A rope holding hook to be held in the double gutter receiving recess is formed so that its opening faces toward the guiding rope part, and a steel wire is installed in the middle part so that the rope holding hook is pressed into the gutter receiving recess. Further, an elastic stopper is attached to one side of the steel wire to push the hook at the tip between the thread guiding part and the rope holding hook, and the middle of this stopper is attached to the hook. When hanging the attachment/detachment tool on the main line, remove the stopper hook from between the guide rope and the rope hook, release the rope hook, and open the gutter holder recess. Hang it on the main rope,
After hanging, the rope holder hook was returned and the stopper hook was inserted between the lead weaving part and the rope holder hook to stop the movement of the rope holder hook. Since the rope cannot be removed from the main line unless the stopper is removed at the same time, the elasticity of the attachment and detachment device is made weaker than before, making it easier to attach and detach, and the purpose of completely preventing the attachment and detachment device from coming off naturally is achieved. be.

次に本考案に係る延縄漁用の枝縄着脱具の実施の一例を
図面に付き説明すれば下記の通りである。Next, an example of the implementation of the branch line attaching/detaching device for longline fishing according to the present invention will be described below with reference to the drawings.

図中１及び１′は中間に巻曲げ２を形威しては゛ねをき
かせる様にした鋼線の一方及び他方で、その一方１の端
部にはくの字形の導線部３を有する線受凹部４を二重に
形成し、他方１′の端部には前記二重の線受凹部４に挾
まれる縄押え鉤５を、その開口が前記導線部３の方向へ
向く様に形成しである。In the figure, 1 and 1' are one and the other of steel wires with a winding 2 formed in the middle so as to be twisted, and one of the wires 1 has a dogleg-shaped conductor part 3 at the end. A double 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.

６は弾性ストッパーで、その一端を鋼線の一方１へ溶接

鉤８とは反対の方向へ張出す張出部９を形威しである。Reference numeral 6 denotes an elastic stopper, one end of which is attached to one of the steel wires 1 by welding or a winding fitting 7, and the conductive wire portion 3 is attached to the tip.
A stop hook 8 is provided to be inserted between the rope holding hook 5 and the rope holding hook 5, and a projecting portion 9 extending in the opposite direction from the stop hook 8 is provided in the middle.

１０は巻曲げ２に結着した枝縄で、先端に釣針（図面に
は示していない）を取付けである。10 is a branch rope tied to the winding 2, and a fishhook (not shown in the drawing) is attached to the tip.

１１は幹縄で、これの繰出し時着脱具を取付け、引上時
着脱具を外すものである。Reference numeral 11 is a main rope, to which a detachable device is attached when it is let out, and to which it is removed when it is pulled up.

幹縄１１から外れ、枝縄と釣針を失うことがなくなる。An example of the implementation of the branch line attaching/detaching device for longline command according to the present invention has the configuration as described above, so when letting out the main line 11,
When the attachment/detachment tool is grasped and the protruding part 9 of the elastic stopper 6 is first pressed with the index finger, the stopper 6 moves from the position shown by the solid line to the position shown by the chain line in FIG. Remove the locking hook 8 that was inserted between the two. Next, squeeze the steel wires 1 and 1' so that they are close to each other. Due to the deformation of the winding portion 2, the steel wires 1 and 1' are separated from each other in the drawing. The state shown in FIG. 1 is changed to the state shown in FIG. 2, and the wire receiving recess 4 is opened. At this time, the wire receiving recess 4 is hung on the main rope 11 by being guided by the conductor 3, and the attachment/detachment tool is gripped. If you loosen the steel wires 1 and 1
' means to return from the state shown in FIG. 2 to the state shown in FIG. At this time, the elastic stopper 6 is also restored, and the stop hook 8 is inserted into the gap between the conductor part 3 and the rope holding hook 5 to stop the movement of the steel wires 1 and 1'. No matter what kind of force is applied, the attachment/detachment tool will not come off the main line 11 and the branch line and fishing hook will not be lost.

しかし、幹縄１１の引上げを行うとき、前述の様にスト

簡単に取り外されるものである。However, when pulling up the main rope 11, if the stopper 6 is removed and force is applied to the steel wires 1 and 1' as described above, the rope holding hook 5 will escape and the wire receiving recess 4 will be opened, allowing the attachment and detachment. The fittings are easily removed.

ものである。As mentioned above, when the branch line attaching/detaching device for longline command according to the present invention is grasped, the overhanging part of the stopper is first pressed down, and after the stop hook is removed from the gap between the conductor part and the rope holding hook, the steel The wire deforms and opens the wire receiving recess, but when you loosen your grip on the attachment/detachment tool, the steel wire returns, and after closing the wire receiving recess with the rope hook,
The hook of the stopper enters the gap between the conductor part and the rope holding hook and keeps the steel wire immobile, so the attaching/detaching tool can be attached to and detached from the main rope with a single touch, making it suitable for high-speed feeding and pulling of the main rope. It is fully compatible with this method, and once attached, the attachment/detachment device will never come off unless the stopper is removed manually, eliminating the loss of branch lines during fishing, which previously occurred due to detachment of the attachment/detachment device. This can prevent loss of fishing gear and decrease in catch.

就労にも大きな効果を奏するものである。In addition, since this attachment/detachment tool uses a stopper to prevent detachment, 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. Not only does this contribute to labor savings and efficiency, but it also eliminates the risk of injury to the hands and fingers even when multiple attachments and detachments are performed, which has a significant effect on the safety of workers.
