Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a bobbin around which a fishing line is wound, and more particularly to a fishing line bobbin provided with a fishing line hooking member for hooking the end of the fishing line.

[Background of the idea]

The bobbin around which the fishing line is wound is generally made of a synthetic resin material. 6th
The figure shows a conventional synthetic resin fishing line bobbin in a perspective view. This conventional example is
This is similar to that disclosed in Japanese Utility Model Publication No. 26623 or Japanese Utility Model Application Publication No. 55-25490.

This fishing line bobbin is composed of a cylindrical main body 1 and a pair of flanges 2 integrally formed on the edge thereof. Further, a recess 3 is formed on the side surface of the cylindrical body 1 inwardly. A fishing line 4 is wound around the outer periphery of the cylindrical body 1. A plurality of fishing line bobbins of this type are connected in a row with their flanges 2 in close contact with each other, and a long fishing line 4 is sequentially and continuously wound around the plurality of fishing line bobbins. At the retail stage, the number of fishing line bobbins is selected according to the length desired by the consumer.
is cut to the desired length. Therefore, the cut end of the fishing line must be hooked onto the bobbin. In the conventional example shown in FIG. 6, a fishing line hooking member 5 for hooking an end portion 4a of a cut fishing line 4 is provided at one location on the collar portion 2.

The fishing line hanging member 5 provided in the conventional example is made of an elastic material such as rubber or nylon, and is attached to the collar 2 by being glued or fitted. ing. A notch 5 is formed in the fishing line hanging member 5 exhibiting this elasticity.
a is formed, and the collar portion 4 of the cut fishing line 4
is held by intervening within this notch 5a.

[Problem that the invention attempts to solve]

However, the fishing line hooking member 5 provided in the above-mentioned conventional fishing line bobbin is attached to the collar portion 2, and a cutout 5a for holding the fishing line collar portion 4a is provided.
extends in the radial center direction of the collar portion 2. Therefore, the fishing line 4 wound around the outer peripheral surface of the cylindrical body 1
If the winding diameter is increased by making the thread longer, the notch 5a will be blocked from the inside by the fishing line 4 wound around the bobbin, making it difficult to reliably insert the fishing line flange 4a into the notch 5a. It turns out you can't do it. Therefore, the length of the fishing line 4 that can be wound around the outer periphery of a fishing line bobbin provided with this type of fishing line hanging member 5 is limited.

Furthermore, in the conventional example shown in FIG.
Since it is attached to the thin collar portion 2, there is a drawback that a sufficient area for the attachment portion of the fishing line hooking member 5 cannot be secured. Therefore, when the fishing line hooking member 5 is bonded to the collar portion 2, sufficient adhesive strength cannot be obtained. In addition, in the device disclosed in Japanese Utility Model Publication No. 57-26623, a mounting recess is provided that penetrates deeply into the bobbin from the side surface, and the projection provided on the fishing line hooking member 5 is fitted into this recess. Fixed. Therefore, the fishing line hooking member 5 must be formed into an L-shape, and the thickness of the cylindrical body 1 as a whole must be made thicker than necessary in order to form a recess for fitting.

The present invention solves the above-mentioned conventional problems by making the end of the fishing line securely latched, and by forming a holding protrusion that provides the fishing line latching part, the overall wall thickness is made larger than necessary. It is an object of the present invention to provide a bobbin for fishing line which does not need to be made and has increased strength.

[Specific measures to solve the problem]

The fishing line bobbin according to the present invention includes a cylindrical body around which a fishing line is wound, a flange provided on the outer periphery of both ends of the cylindrical body, and an inner space of the cylindrical body formed on one side. an open recess, a center hole formed in the bottom of the recess, a detent groove formed in a concave shape from the periphery of the central hole, and a holding protrusion extending from the periphery of the detent groove in the direction of the opening. is integrally formed from resin,
This holding protrusion is characterized by a fishing line hooking portion.

[Effect]

In this fishing line bobbin, the holding protrusion is integrally formed to stand up from the bottom of the recess on the side surface, so the fishing line can be hung by pulling the collar of the fishing line wound around the outer peripheral surface of the cylindrical body toward the recess. It can be easily stopped by hanging it on the part. Also,
The fishing line hooking part is provided in the recess on the side, so even if the fishing line wound on one bobbin is made long and its winding diameter is increased until it approaches the outer edge of the collar, the end of the fishing line cannot be held in place. It can be reliably latched to the latching portion. In addition, since the holding protrusion is integrally projected from around the detent groove formed at the edge of the center hole formed on the bottom of the concave portion of the bobbin, the holding protrusion also serves to reinforce the area around the detent groove. Also, the design around the center hole does not look strange.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5B.

FIG. 1 is a perspective view showing an embodiment of the fishing line bobbin according to the present invention, FIG. 2 is an enlarged perspective view showing a holding protrusion and a fishing line hooking member, and FIG. 3 is a perspective view of the fishing line bobbin of FIG. 1. 4 is a cross-sectional view of FIG. 3, FIG. 5A is an enlarged front view showing the fishing line hooking member,
FIG. 5B is a side view of FIG. 5A (view along the arrow in FIG. 2).

The fishing line bobbin shown in FIG. 1 is made of a hard synthetic resin material. This fishing line bobbin has a cylindrical main body 11 and a pair of flanges 12 extending integrally from the edge thereof. A recess 13 formed inside the thick wall of the cylindrical main body 11 is open on the right side surface of the fishing line bobbin in the drawing.
Further, as shown in FIG. 4, a ring-shaped fitting protrusion 14 is protruded from the left side surface of the bobbin in the drawing.
This ring-shaped fitting protrusion 14 is formed to have a diameter that allows it to be fitted into the recess 13. Cylindrical body 1
In the process of winding the fishing line 15 around the outer peripheral surface of the fourth
As shown in the figure, the ring-shaped fitting protrusion 14 is fitted into the opening edge of the recess 13 of the adjacent bobbin, and a plurality of fishing line bobbins are connected with their flanges 12 in close contact with each other. be done. In the process of winding the fishing line 15, a long line is sequentially and continuously wound around the outer peripheral surface of the cylindrical body 11 of a plurality of connected fishing line bobbins. At this time, the fishing line 15 that crosses the adjacent bobbin
passes through a notch 12a formed in the flange 12.

A center hole 17 is provided at the center of the bottom surface 16 of the recess 13.
is formed. As shown in FIGS. 2 and 3, a detent groove 17 is provided at the edge of the center hole 17.
a is formed. In the process of winding the fishing line 15, the center hole 17 of the bobbin is held by the shaft. This allows the bobbin to be integrated with the shaft. As shown in FIG. 2, a ring-shaped thick part 18 is formed around the center hole 17 to ensure the substantial length of the hole.
A holding protrusion 19 is integrally formed by a portion of the holding protrusion 8 rising from the periphery of the detent groove 17a. The locking groove 17a extends to the inner surface of the holding projection 19, and the holding projection 19 also serves to reinforce the locking groove 17a. A fishing line hooking member 21 is held on this holding protrusion 19 .

The fishing line hooking member 21 is made of a resin material that exhibits deformable elasticity, such as a rubber material or nylon. In the embodiment shown, the retaining projection 19
A holding groove 19a is formed in the holding groove 19a, into which a fishing line hooking member 21 is fitted and held. However, the fishing line hooking member 21 may be adhered to and held by the holding protrusion 19. As shown in FIGS. 5A and 5B (view from the arrow in FIG. 2), a notch 21a is formed in the fishing line hooking member 21. For example, the notch 21a is formed in a wedge shape so that the width becomes narrower as it goes inside, as shown in FIG. 5B. Further, a tapered surface 21b for guiding the end of the fishing line 15 to the notch 21a is formed on the outer surface (the surface opposite to the center hole) of the fishing line hooking member 21.

Note that the holding protrusion 19 and the fishing line hooking member 21 are formed in such a size that their tips do not protrude from the side surface of the bobbin, and as shown in FIG. 4, when a plurality of bobbins are connected, the holding protrusion 19 19 or the fishing line hooking member 21 is designed to prevent it from hitting the adjacent bobbin.

In the fishing line bobbin having the above structure, as shown in FIG. A fishing line 15 is wound around the surface. The fishing line 15 is wound onto one bobbin and then continuously wound onto the adjacent bobbin. At the retail stage, the consumer specifies the number of bobbins depending on the desired length of the fishing line 15, and the required number of bobbins are sold as a set. The end 15a of the fishing line 15 cut at this time is guided toward the recess 13 from the guide groove 12b (see FIG. 1) formed in the collar 12, and inserted into the notch 21a of the fishing line hooking member 21. and retained. Since the fishing line hooking member 21 is made of an elastic material, the fishing line 15
The end portion 15a is securely held by the notch 21a. In the example of FIG. 5B, the notch 21a of the fishing line hooking member 21 is formed in a wedge shape, so that
When the fishing line 15 is thick, it is held near the opening end of the notch 21a, and when the fishing line 15 is thin, it is held near the opening end of the notch 21a.
It will be held on the back side of 1a.

Note that in the illustrated embodiment, the holding protrusion 19 is formed integrally with the thick wall portion 18 around the center hole 17, but the holding protrusion 19 is not limited to this position, and is formed on the bottom surface 16 of the recess 13. It may be made to protrude from any location.

(Effects of the invention) According to the invention, since the holding protrusion having the fishing line hooking part is provided in this part by utilizing the wide internal space of the cylindrical main body, the fishing line hooking part of sufficient size can be placed inside the space. A stop portion can be formed, and the end of the fishing line can be reliably hooked. In addition, by guiding the end of the fishing line wound around the outer peripheral surface of the cylindrical body into the recess and letting it hang with the fishing line hanging member, the fishing line end can be hung inside the recess. Compared to the case where the fishing line is located on the collar or the side of the main body, the end of the fishing line can be treated more neatly, and there is no problem such as the end of the fishing line getting caught on something else and unraveling.

Further, by providing the holding protrusion so as to protrude from the periphery of the anti-rotation groove formed at the edge of the center hole bored in the bottom of the recess, the anti-rotation groove can also be reinforced. In any case, a thick part around the center hole is required, so by being able to form this thick part and the holding protrusion in one piece, it becomes easier to create a molding die. Since the holding protrusions can be made continuous, sink marks and distortions are less likely to occur during molding.
Further, since the holding protrusion is formed integrally from the periphery of the detent groove, there is no need to increase the thickness of the portion other than this portion.
