Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing line spool.

[0002]

2. Description of the Related Art Conventional fishing line spools are disclosed in
No. 136854. That is, in the one disclosed herein, a fishing line winding body portion partitioned by flanges on both sides is formed on the outer periphery of a cylindrical main body having a predetermined width in the axial direction, and the The central portion has a shaft tube portion having a cylindrical shape smaller in diameter than the fishing line winding body portion, and is connected by a plate-shaped support portion connecting the shaft tube portion and the fishing line winding body portion. In addition, a plurality of ribs are formed to support the support portion, the fishing line winding body portion, and the shaft tube portion to prevent bending of the line winding.

The support portion is usually formed on one side of the bobbin so as to be continuous with one side surface of the flange, and a nameplate or the like can be attached to the outer side surface. It is configured as follows.

[0004]

However, in the case of such a structure, since the supporting portion is shifted to one side portion,
Due to differences in the melting temperature of the resin material flowing between the one side and the other side of the bobbin during molding and the time to reach the end (based on the difference from the gate), distortion during molding is caused. Is likely to occur, resulting in variations in product accuracy. When such distortion occurs, the fishing line is shaken during rotation during winding, and it becomes impossible to mount the fishing line on the winding shaft of the line winding machine and perform parallel winding while rotating at high speed.

[0005] Further, on the other side of the bobbin, a taper for removing the molded product from the mold smoothly is required, which makes the design difficult.

Further, when a fishing line is wound around the bobbin, since the winding body is in a cantilevered state,
By tightening the line, the other side of the winding trunk is more easily bent than one side, thereby making it difficult to wind the fishing line in parallel,
The fishing line had a line habit, causing troubles such as line entanglement and line breakage during actual fishing.

The present invention has been made in view of such problems of the prior art, and it is possible to eliminate the occurrence of distortion of a product (line for fishing line) at the time of molding, thereby preventing variation in product accuracy. Another object of the present invention is to provide a fishing line bobbin that can be wound in parallel while preventing the winding trunk portion from bending when the line is wound, and has no habit.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a fishing line winding cylinder having a cylindrical bobbin main body having a predetermined width in the axial direction and having flange portions on both sides at the outer periphery thereof. Part, a shaft cylinder part having a cylindrical shape smaller in diameter than the fishing line winding body part at the center part of the bobbin, and a connection between the shaft cylinder part and the winding body part connected by a plate-shaped support part. In the fishing line spool in which a plurality of ribs are formed to support the support portion, the fishing line winding body portion and the shaft tube portion, and to prevent deflection of the line winding, the plate-shaped support portion is provided at the center of the line winding in the axial direction. It is characterized by being arranged in a part.

Further, the present invention is arranged such that a side surface on one side of the rib is substantially flush with an outer surface of one of the flange portions so that a nameplate can be attached to the bobbin. Features.

Further, the present invention is characterized in that a ventilation hole is formed for communicating the airtight space defined by the flange, the rib, the support portion, and the nameplate with an external space.

[0011]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

(First Embodiment) FIGS. 1 to 6 show a first embodiment of the present invention. A fishing line spool 1 according to the first embodiment is a cylindrical bobbin bobbin. The flanges 11 and 12 are integrally formed on both sides of the portion 10.

At the center of the bobbin trunk 10, a shaft tube portion 14 having a shaft hole 13 for mounting the bobbin 1 on a bobbin of a bobbin not shown is formed with a plate-shaped support member 15 and a plurality of shaft members. It is provided integrally via a rib 16.

A plate-like support member 15 for connecting the bobbin trunk portion 10 and the shaft tube portion 14 is disposed so as to be located at a central portion in the axial direction. The thickness (axial dimension) of the support member 15 in the present embodiment is set to be larger than the thickness of the winding body 10, and in combination with the ribs 16 located on both sides of the support member 15, When the yarn is wound around the winding body 10, no bending occurs at both ends of the winding body 10.

In the present embodiment, eight ribs 16 are formed radially on one side. The outer surface 16a on one side of the rib 16 is configured to be coplanar with the outer surface of the flange 12 and the outer surface 14a of the shaft tube portion 14. On this surface, as shown in FIGS. 2 to 4, a nameplate 2 such as a seal or a label on which an item name or the like is written is attached.

The outer surface 16b of the rib on the other side is formed as an inclined surface which gradually descends from the flange 11 toward the shaft cylinder portion 14. In the present invention, the outer surface 16b of the rib may be configured so as to be flush with the outer surface of the other flange 11, similarly to the outer surface 16a.

When the nameplate 2 is attached, an airtight space is defined inside by the winding body 10, the support 15, the shaft cylinder 14, the ribs 16 and the nameplate 2. In the airtight state, the nameplate 2 may be lifted during the attaching operation, and the attaching operation becomes complicated.
In order to avoid this, in the present invention, a ventilation hole 17 for communicating the airtight space with the outside is formed.

In the present embodiment, the ventilation hole 17 is formed in a concave groove shape on the outer surface of the shaft cylinder portion 14, and is opened on the inner peripheral surface of the shaft hole 13. Note that the ventilation hole 17 may be a hole penetrating the shaft cylinder portion 14 instead of the groove shape. Further, the place where the ventilation hole is formed is not limited to the shaft cylinder portion 14, and as shown in FIG. May be such that the air escapes to the opposite surface side when attaching. Furthermore, a hole may be formed in the thickness direction at a position corresponding to each airtight space of the nameplate 2.

In the illustrated example, since eight ribs 16 are formed and eight airtight chambers are defined, eight air holes 17, 19 are formed corresponding to each airtight chamber. However, the present invention is not limited to this, and at least one such ventilation hole 17 and 19 may be formed, and the rib 16 may be formed with a ventilation hole that allows the airtight chambers to communicate with each other. Good thing.

[0020]

As described above, according to the present invention, since the supporting portion for connecting the winding drum portion and the shaft cylinder portion is formed at the axial center portion of the winding drum portion, the support portion is substantially formed in the axial direction. It becomes symmetrical, whereby the melting temperature of the resin material flowing on both sides of the bobbin during molding and the time to reach the end (distance from the gate) become uniform, and distortion during molding can be prevented.
Not only can variations in product accuracy be eliminated, but also it is possible to prevent rotational fluctuation of the line during winding of the fishing line, and it is possible to perform high-speed parallel winding.

Further, the fishing line bobbin of the present invention has a substantially symmetrical structure on both sides of the center in the axial direction and a short distance between the support portion and both side portions, so that the taper of the die can be reduced.
The design of the mold is facilitated.

Further, in the present invention, since the supporting portion for connecting the winding drum portion and the shaft cylinder portion is formed at the axial center portion of the winding drum portion, when the fishing line is wound around the winding drum portion. Since the winding body does not bend only to one side,
The fishing line can be reliably wound parallel to the winding body, and the fishing line does not have a line habit, thereby preventing various troubles such as line entanglement and line breakage during actual fishing.
