Description

[Detailed Description of the Invention] (Industrial Application Field) This invention involves suspending a long rope (e.g. 10 to 20 meters) into the water, keeping a distance slightly larger than that of an adult mollusk (approximately 15 cm for a scallop), so that the axis is perpendicular to the rope. Insert it in the shape of
Scallops for cultivating young shellfish into adult shellfish by inserting ear holes drilled in the ears of young shellfish into each side of the shaft protruding from the rope to support the young shellfish in a suspended state, and suspending the ropes into the water to cultivate the young shellfish into adult shellfish. Concerning plastic handles for cultivating shellfish by suspending their ears.

(Prior art) When inserting the ear hole of a shellfish into each side of the shaft as such, the tip is pushed down against elasticity on the shaft by the edge of the hole, and when the ear hole passes, it restores itself and stands slanted. A device was developed in 1975 that was equipped with an integral check claw to prevent the shellfish from falling off each side of the shaft.
It is publicly known from Publication No. 30461.

(Problem to be Solved by the Invention) The above-mentioned rope is inserted into a long rope in countless orthogonal directions at a predetermined distance in the vertical direction, and then young shells are inserted into each side of the shaft for one rope. Insert it into the ear hole. During this installation process, if long ropes come into contact with each other midway through the rope, each side of the shafts of the two inserted hands will get stuck in the rope, and the slanted check claws will get caught, often making it impossible to remove them from the rope. In this case, the installation work must be interrupted and the pierced side must be removed from the rope, but this takes time and reduces work efficiency.

(Means for solving the problem) Therefore, the present invention makes the cross-sectional shape of the section from the tip to the middle of the side part of the shaft larger than the ear hole of the shellfish, and forms a longitudinal groove in the section, It is characterized in that the ear hole is fitted into the section by closing the groove against elasticity.

(Function) The cross-sectional shape of the section from the tip to the middle of the side of the shaft is larger than the ear hole of the shellfish, but by closing the groove in the section against elasticity, it becomes large enough to fit the ear hole. Deforms elastically. Therefore, by deforming it like that and inserting it into the ear hole from the tip of the side part,
When the ear canal passes through the above section, the groove restores and opens.

(Example) In each of the illustrated examples, 1 is a well-known long rope with a diameter of about 1 cm, which is hollow and has a braided cylinder wall;
2 shows the shaft of the hairpin integrally molded from the elastic plastic of the present invention.

In the case of scallops, the ears of the young shellfish 3 have a diameter of 1.0~
Drill an ear hole 4 with a diameter of about 1.6 mm (preferably a diameter of 1.2 mm or less to prevent the occurrence of dead shellfish during cultivation). The length of the shaft 2 is approximately 6 cm when supporting one scallop on each side of the shaft, and the center of the shaft 2 has protrusions 5, 5 with a height of approximately 4 to 5 mm attached to the thick rope 1. Provided with a spacing slightly larger than that of the
Pass the protrusion 5 on that side through the mesh of the tube wall of the rope in the diametrical direction and insert it orthogonally (Fig. 1), and use both protrusions 5 as stoppers to insert the rope in the axial direction. Prevent large movements.

The sides 6 of the shaft 2 are therefore the parts from each end of the shaft to the respective projections 5.

In the first embodiment of FIGS. 1 to 5, each side 6 of the shaft 1
As shown in Fig. 3, the section 7 of about 7 to 8 mm from the tip to the middle of the section is made larger than the ear hole 4 of the shellfish, and an axial groove 8 is provided in the section 7, and the remaining part of the side section is The cross-sectional shape of the section 6' is approximately the same as or slightly smaller than the ear canal 4, as shown in FIG.

The groove 8 is V-shaped in this embodiment, and the section 7 consists of two sector-shaped pieces 9, 9 connected by a thin hinge 8' at the bottom of the groove 8, as shown in FIG.
By bending and bringing the opposite sides of the groove 8 closer together, the edges 9', 9' of both sector-shaped pieces, which were protruding outside the annular aperture 4, enter the aperture of the auricular aperture, and thus this section 7 It becomes possible to fit the ear hole 4 of the shellfish into the hole. In order to easily fit the ear hole through the entire length of the section 7, the groove 8 may be slightly extended into the remaining section 6' as shown in FIG.

As a result, the groove 8 of the section 7 from the tip of each side part 6 to the middle is closed, and the ear hole 4 of the shellfish can be inserted into the section 7. When the ear hole of the shellfish passes through the section, the groove 8 opens. The cross-sectional shape of the above section remains larger than the ear hole of the shellfish. The shell is thus received at the end of the section 7 and supported on each side 6 of the shaft without falling off.

Then, a long rope in which a countless number of these handguns are inserted perpendicularly at predetermined intervals comes into contact with each other in the middle, and even if the handguns are stuck in the rope, they can easily come out because there are no check claws.

The cross-sectional shape of the remaining side section 6' in this embodiment is circular, but it may have any shape as long as it enters the aperture of the ear canal 4. Further, although the groove 8 is opened upward, the opening direction is also arbitrary.

6 to 8 show a second embodiment, and the main difference between this and the first embodiment is that the cross-sectional shape of the remaining section 6' of the side portion 6 is the same as that of the section 7, except for the portion adjacent to the section 7. Similarly to section 7, the ear hole 4 is made larger than the ear hole 4 of the shellfish, and the ear hole 4 is made larger than the ear hole 4 of the shellfish, and the cross-sectional shape of the adjacent part is as shown in FIG.
The reason for this is that a constriction 10 is provided which is smaller than the corridor. In this embodiment, the section 6' has the same cross-sectional shape as the section 7 consisting of the two sectors 9, 9, and the groove 8 is provided along the entire length of the section 6'.
It may have any shape without being limited to this. The cross-sectional shape of the constricted portion 10 is also almost the same as that of the section 7 except that it does not have corners 9' and 9' protruding from the aperture of the ear canal. It can be any shape.

This embodiment also closes the groove 8 of the section 7 and closes the ear hole 4 of the shellfish.
can be made to reach the constriction part 10. Then, when the ear canal reaches the constricted part 10, the groove in section 7 opens, and the front and back of the constricted part 10 are larger than the cross-sectional shape of the ear canal, so the shellfish is supported by the constricted part 100. The length in the axial direction of the constricted portion 10 is determined based on the thickness of the ear of an adult mollusk, and may be about 2 mm.

If a rope gets stuck in the side of the handle of this embodiment, it can be pulled out without any trouble.

The third embodiment shown in FIG. 9 is a modification of the second embodiment, in which the remaining section 6' is lengthened, and a constriction 10' similar to that provided in the adjacent section 7 is provided in the middle. There is. Therefore, according to this embodiment, it is possible to support a plurality of shellfish on the sides.

Groove 8 provided in section 7 from the tip of the side part to the middle
is not limited to one, but may be two or more, and the method of closing the groove for fitting the ear hole 4 of the shellfish into the section 7 is to bring the opposite sides of the groove closer together. Not limited.

In the fourth embodiment shown in FIGS. 10 to 12, the cross-sectional shape of the section 7 is approximately H-shaped, and has two grooves 11, 11 having approximately U-shaped cross sections back to back. Each end 12' of the side walls 12, 12 is connected to the ear hole 4.
It protrudes outward from the porthole and has a cross-sectional shape larger than the ear canal.

Therefore, by bending the ends of the pair of side walls toward each other as shown by the arrows and closing the open surfaces of the grooves 11, 11, the ear canal 4 is formed in section 7, making it smaller than the aperture of the ear canal. can be inserted.

In addition, the cross-sectional shape of the remaining section 6' has a total length that is equal to the ear canal 4.
Although it may be smaller, in this case, a constricted portion 10 with an H-shaped cross section smaller than the ear canal is formed adjacent to the section 7, as shown in Fig. 12, and the other cross-sectional shapes are sections larger than the ear canal. It is set the same as 7.

The embodiment shown in FIGS. 13 and 14 is a modification of the fourth embodiment described above, and the section 7 has a cross-sectional shape of two grooves 1 back to back.
1 and 11, but what protrudes from the aperture of the ear canal 4 are the paired side walls 12 forming each groove.
The difference is that only one end 12a' is present between a and 12b. Therefore, in this embodiment, the side wall 1
By bending the end 12a' of 2a toward the end of the other 12b in the direction of the arrow and closing the groove 11, the ear hole 4 of the shellfish can be inserted into the section 7.

In both of the above embodiments, if each side of the handle is stuck in the rope, it can be easily pulled out.

In each of the above-mentioned embodiments, the groove in section 7 can be closed by sandwiching it between the fingers, but by making the tips of each side tapered as shown in the figure so that they can penetrate into the ear canal shallowly. After entering the ear canal shallowly, by pushing it in, the ear canal can be inserted into the section 7 while closing the groove with the edge of the ear canal, resulting in good workability.
Further, by making the cross-sectional shape of section 7 and the remaining section 6' excluding the constricted portions 10 and 10' exactly the same, it is possible to pull out the rope without any resistance when the side portion is stuck in the rope.

(Effects of the Invention) According to the present invention, it is possible to provide a handle that can be easily pulled out even if each side part is stuck in a rope, and that can be inserted into the ear hole of a shellfish and supported without falling off, thereby eliminating the need for ear hanging work. It has an epoch-making effect that contributes to further improvements in efficiency and efficiency.
