Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spike, and particularly to a spike for holding the tip of a rope thread and passing it through the mesh of a fishing net when sewing a fishing net such as a trawl net.

(Prior art) Trawl nets used for trawl fishing include sleeve nets,
The trawl net is made up of three parts: the body net and the tangled end. First, these three parts are made individually, and these partial nets (sleeve net, body tether, and tangled end) are connected to complete the trawl net. Each of the above partial nets is produced through a lacing process; for example, the knotted end is produced by lacing the dorsal mesh and abdominal mesh.

The above lacing is performed using a fine needle or spike. Conventional spikes have a curved shape with an outer diameter that gradually tapers toward the tip.
A mesh thread insertion hole for inserting a rope mesh thread is formed inside thereof.

(Problem to be solved by the invention) However, in the case of conventional spikes, the rope net thread was held by simply inserting the end of the rope thread into the thread insertion hole of the spike, so that There was a problem in that the rope mesh threads fell off the spikes, and each time the rope mesh threads fell off, the rope mesh threads had to be reinserted into the spikes.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a spike with good retention of rope threads that can prevent the rope threads from falling off from the spikes during the fishing net sewing process. There is a particular thing.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention consists of a tapered cylindrical body whose distal end is curved and whose outer diameter gradually decreases from the proximal end to the distal end. The spike body is characterized by comprising a spiky body, and an anchoring device rotatably provided in a notch formed at the base end of the spiky body and for retaining the rope net thread. be.

(Function) The present invention uses the above-mentioned means to rotate the anchoring device and insert the rope net thread between the spike body and the anchoring device in an open state, and then rotate the anchoring device to connect the rope net thread to the spike body and the anchoring device. The rope net thread is held between the anchoring tool and the rope thread, whereby the rope thread can be firmly held so as not to fall off from the spikes, and the work efficiency of the fishing net sewing work is improved.

(Embodiment) Hereinafter, an embodiment of the spike according to the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 shows a perspective view of the spike 1, in which the spike main body 2 moves from the proximal end 2a (the rear end side of the center of the main body) toward the distal end 2b (the distal end of the center of the main body). It consists of a tapered cylindrical body with an outer diameter that gradually decreases in diameter, and the distal end 2b is curved and has a needle-like tip. In addition, the base end 2a of the spike body 2 has a notch 2c.
is formed, and this notch 2c is formed on the surface side along the curved surface side of the spike body 2, and this notch 2c
extends over a substantially semi-cylindrical portion of the cross section, and extends over almost the entire area of the base end 2a along the axial direction of the base end 2a. A semi-cylindrical anchor 3 having serrated engagement portions 3a on both side edges is pivotally attached to the notch 2c. The base end of the anchor 3 has a pivot portion 3b wound into a roll, while the base end 2a near the end of the notch 2c has a locking piece 2d formed by bending its side wall. , 2d, and when the pivot portion 3b is engaged with the locking pieces 2d, 2d, the locking tool 3 can be rotated relative to the spike main body 2 (see Fig. 2). reference).

Next, the operation of the spike according to the present invention constructed as described above will be explained with reference to FIGS. 3 to 5.

First, as shown in FIG. 3, with the anchor 3 open, the rope mesh 5 is inserted so that its base end 5a is located near the pivot 3b. Next, the anchoring tool 3 is rotated to sandwich the rope net thread 5 between the spike body 2 and the anchoring tool 3, as shown in FIG. At this time, the serrated engagement portions 3a of the anchoring device 3 firmly bite into the rope mesh 5, so that the rope mesh does not fall off. In this state, for example, if the rope 7 and the fishing net 8 are sewn together as shown in FIG. 5, the tip 2b of the spike body 2 is sharp and curved, making it easy to pass through the net and lift the object. I can work without any problems.

In this embodiment, the serrated fasteners are provided only on the fasteners, but they may also be provided on both side edges of the spike body 2 on the proximal end 2a side. Furthermore, the engaging portion 3a is not limited to a sawtooth shape, but may have any shape that bites into the rope mesh thread.

(Effects of the Invention) As is clear from the description of the embodiments, the present invention has a spike body consisting of a tapered cylindrical body with a curved tip, and a rope mesh rotatably attached to the notch of the body. Since a locking device is provided to hold the thread, the rope net thread can be tightly caught between the spike body and the fastener, and the rope net thread can be prevented from falling off from the spike during sewing work. can. Thereby, it is possible to improve the work efficiency of sewing the rope net and the fishing net.

Further, since the tip of the spike according to the present invention is tapered and curved, it can easily pass through the mesh of a fishing net, and suturing work can be performed without lifting the object.
