Description

The present invention relates to spools.

Patent Document 1 discloses a spool including a spool body portion (shaft portion) and a pair of flange portions extending radially outward from both ends of the spool body portion.

Japanese Unexamined Patent Publication No. 2020-127378

By the way, in the conventional spool as in Patent Document 1, when the line wound on the spool is removed from the spool, it is necessary to gradually extend the line while rotating the spool. For this reason, if it is desired to dispose of the line, it is necessary to gradually extend the line or cut the line in that way, which is troublesome to remove the line from the spool.

The present invention has been made in view of such a point, and an object of the present invention is to make it possible to easily remove a line wound on a spool from the spool.

In order to achieve the above object, in the present invention, the spool is separated so that the line can be removed from the shaft portion.

Specifically, the first invention is a spool in which a first flange and a second flange are provided at both ends in the axial direction of a shaft portion around which a fishing line is wound, and the first invention includes the first flange. It includes one member and a second member including the second flange and configured to be separable from the first member.

In the first invention, since the spool is configured to be separable into a first member including the first flange and a second member including the second flange, at least one of both flanges is wound around the shaft portion. It can be pulled away from the line. Therefore, the line can be removed from the shaft portion by shifting the line along the axial direction toward the side without the flange. In this way, the line wound on the spool can be easily removed from the spool.

By the way, when the first member and the second member are manufactured by molding with a mold, a small groove may be formed at a boundary portion where both members are divided from each other. I want to prevent the line wound around the shaft from biting into such a groove.

Here, in the first invention, the shaft portion is divided into a first part which is a part of the first member and a second part which is a part of the second member. The division surface that divides the first part and the second part is parallel to the axial direction of the shaft portion, or is not parallel to the extending direction of the line wound around the shaft portion. The tilt angle of the part from the axial direction is small.

In the second invention, the dividing surface is not parallel to the direction in which the line extends on the outer peripheral surface of the shaft portion. Therefore, there is no possibility that the line will bite into a small groove that may be formed by the divided surface on the outer peripheral surface of the shaft portion. Therefore, the spool becomes easy to use.

In the third aspect of the invention, in the first or second invention, the first member and the second member are made of resin and have the same shape as each other. Therefore, both members can be molded using the same mold, which simplifies manufacturing.

In the fourth aspect of the invention, in any one of the first to third inventions, the first state when the line is wound and at least a part of the contact portion in contact with the line in the first state are It can be changed between the second state in which the line is loosened from the first state by being displaced inward in the radial direction of the shaft portion from the first state or being displaced so as not to come into contact with the line. Is.

In the fourth invention, the spool can be changed from the first state in which the line is wound to the second state in which the line is looser than the first state. Therefore, when the first member and the second member are separated from each other and the line is shifted along the axial direction, if the spool is in the second state, the line is loose and it is easy to shift the line along the axial direction. That is, it becomes easier to remove the line wound on the spool from the spool.

The fifth invention further includes, in the fourth invention, a rod member arranged radially inside the shaft portion with respect to the line wound around the shaft portion, and the first state is the rod member. Is in contact with the line and at least a part of the line is separated radially outward from the outer peripheral surface of the shaft portion, and the second state is the state in which the rod member is said to be in the first state. The contact portion in contact with the line is displaced inward in the radial direction of the shaft portion from the first state or is displaced so as not to come into contact with the line, and the line is loosened from the first state. ..

In the fifth invention, a rod member arranged radially inside the shaft portion rather than the line wound around the shaft portion is further provided, and the rod member is displaced to easily change from the first state to the second state. It can be changed. That is, a simple configuration that exhibits the effect of the fourth invention can be obtained.

In the sixth aspect of the invention, in the fifth aspect, an arrangement portion extending in the axial direction for arranging the rod member is provided on the outer peripheral surface of the shaft portion, and the rod member is provided with the arrangement portion. In the sixth invention, the rod member can be changed between the first state and the second state by rotating the rod member in the length direction as a rotation axis. In the sixth invention, the rod member is simply rotated to make the first state. It is possible to change between the state and the second state, and a simple configuration that exhibits the effect of the fourth invention can be obtained.

As described above, according to the present invention, the line wound on the spool can be easily removed from the spool.

It is a perspective view which shows the spool which concerns on embodiment. It is an exploded perspective view of a spool. FIG. 3 is a sectional view taken along line III-III of FIG. FIG. 3 is a view corresponding to FIG. 3 in which the spool is in the second state. FIG. 3 is a diagram corresponding to FIG. 3 according to a modified example of the embodiment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of preferred embodiments is merely exemplary and is not intended to limit the invention, its applications or its uses.

(Embodiment)
-Spool configuration-
1 to 4 show the spool S according to the embodiment. The spool S is attached to an electric or manual winder (not shown) for winding and storing the fishing line L. The line L is not shown in FIGS. 1 and 2.

As shown in FIG. 1, the spool S has a substantially cylindrical shaft portion 10 around which a line L is wound, and a substantially disk-shaped first flange F1 and a second flange F provided at both ends of the shaft portion 10 in the axial direction, respectively. It is composed of a flange F2. The spool S is all made of resin except for the metal rod R described later.

In the following, the "axial direction" means the axial direction of the shaft portion 10. Further, "upper side", "lower side", "left side" and "right side" are used to explain the direction perpendicular to the axial direction in relation to the drawing. Further, the "cross section" means a cross section perpendicular to the axial direction.

FIG. 2 shows a state in which the spool S is disassembled. The spool S includes a first member S1 and a second member S2 separably configured from the first member S1. The first member S1 and the second member S2 have the same shape as each other.

As shown in FIG. 2, the first member S1 includes a first flange F1 and a first portion 11 which is a part (lower half) of a shaft portion 10 extending toward the second flange F2. The shaft portion 10 is divided into a first portion 11 in the lower half and a second portion 12 in the upper half by a dividing surface P parallel to the axial direction thereof. The second member S2 includes a second flange F2 and a second portion 12, and the second portion 12 extends from the second flange F2 to the first flange F1 side. The tip of the first part 11 on the second member S2 side and the tip of the second part 12 on the first member S1 side are hooked on the second flange F2 and the first flange F1, respectively, and both members S1 and S2 are connected to each other. The claw portions X1 and X2 for fixing the above are provided.

FIG. 3 shows a cross section taken along line III-III of FIG. As shown in FIG. 3, in the shaft portion 10, the right portion through which the dividing surface P passes is such that the end faces of the first portion 11 and the second portion 12 are in contact with each other, while the left portion through which the dividing surface P passes is the left portion. A gap 13 is provided in which the end faces E1 and E2 of the first part 11 and the second part 12 are separated from each other. As shown in FIG. 2, the gap 13 extends in the entire axial direction of the shaft portion 10.

Further, as shown in FIG. 2, through holes h1 and h2 penetrating in the axial direction along the extension line of the gap 13 are formed in the first flange F1 and the second flange F2, respectively. That is, the through holes h1 and h2 communicate linearly with the gap 13 (see the alternate long and short dash line in FIG. 2), and the through holes h1 and h2 and the gap 13 are arrangement portions for arranging the rod member 20 described later. It constitutes D.

As shown in FIGS. 2 and 3, the spool S includes a rod member 20 arranged radially inside the shaft portion 10 with respect to the line L wound around the shaft portion 10. The rod member 20 is formed in a shape corresponding to the arrangement portion D so as to be arranged in the arrangement portion D. Specifically, the length of the rod member 20 is substantially the same as the axial length of the arrangement portion D (through holes h1, h2 and the gap 13). The rod member 20 has a cross-sectional shape of 21 and 22 at both ends arranged in the through holes h1 and h2 and an intermediate portion 23 (a portion arranged in the gap 13 of the shaft portion 10) between the both ends 21 and 22. Is different. In detail, the outer peripheral surfaces of both end portions 21 and 22 are formed in a circular cross-sectional shape having a diameter slightly smaller than that of the through holes h1 and h2, while the outer peripheral surfaces of the intermediate portion 23 have the cross-sectional shape of both end portions 21 and 22. It is formed in a shape that is approximately half a circle. That is, the rod member 20 is formed in a shape in which a long member having a circular cross section is cut out in a substantially semicircular cross section except for both ends 21 and 22. With such a configuration, as shown in FIG. 3, the outer peripheral surface of the intermediate portion 23 is a flat portion flatter than the arc portion 23a which is a part of the circle having the cross-sectional shape of both ends 21 and 22 and the arc portion 23a. It has 23b.

The rod member 20 is an arrangement portion D and is rotatable about a rotation shaft 24 along the length direction of the rod member 20. The spool S can be changed between the first state when the line L is wound and the second state L where the line L is looser than the first state by rotating the rod member 20 in that way. ..

Specifically, in the first state, as shown in FIG. 3, the arc portion 23a of the rod member 20 faces the radial outside of the shaft portion 10, and the arc portion 23a (contact portion) is in contact with the line L. Therefore, a part of the line L is separated radially outward from the outer peripheral surface of the shaft portion 10. In the second state, as shown in FIG. 4, the arc portion 23a of the rod member 20 faces the radial inward side of the shaft portion 10. Therefore, in the second state, the arc portion 23a that comes into contact with the line L in the first state is displaced inward in the radial direction of the shaft portion 10 than in the first state, so that it does not come into contact with the line L. As a result, the line L is looser in the second state than in the first state.

A knob portion 25 is provided on the end surface of the end portion 22 on the second flange F2 side of the rod member 20 for the user to pinch and rotate the rod member 20. That is, when the user winds the line L around the shaft portion 10, the rod member 20 is kept in the first state (see FIG. 3), and when the line L wound around the spool S is removed for disposal. Pinch the knob portion 25 of the rod member 20 and rotate the rod member 20 to the second state (see FIG. 4). In the second state, if the first member S1 and the second member S2 are separated from each other and the line L is shifted along the axial direction of the first part 11 and the second part 12, the line L is easily separated from the shaft part 10. ..

A cavity extending in the axial direction is formed inside the rod member 20, and a metal rod R (reinforcing rod member) extending along the rod member 20 is provided in this cavity so as to reinforce the rod member 20. There is. As shown in FIG. 2, a lid for closing the cavity can be attached to the end surface of the rod member 20 on the first flange F1 side, and the lid is configured to prevent the metal rod R from coming out of the cavity. There is.

-Action / Effect-
In the embodiment, the spool S is configured to be separable into a first member S1 including the first flange F1 and a second member S2 including the second flange F2, and therefore one of the flanges F1 and F2. Can be separated from the line L wound around the shaft portion 10. Therefore, if the line L is shifted along the axial direction toward the side where the flanges F1 and F2 are not present, the line L can be removed from the shaft portion 10. In this way, the line L wound around the spool S can be easily removed from the spool S.

By the way, when the first member S1 and the second member S2 are manufactured by molding with a mold, a small groove may be formed at a boundary portion where both members S1 and S2 are divided from each other. We want to prevent the line L wound around the shaft portion 10 from biting into such a groove. Further, the line L wound around the shaft portion 10 is an outer peripheral surface of the shaft portion 10, and some extend in a direction perpendicular to the axial direction and some extend in an inclined direction from the direction perpendicular to the axial direction. In either case, we want to prevent it from biting into the groove as described above.

Here, in the embodiment, since the dividing surface P is parallel to the axial direction of the shaft portion 10, it is not parallel to the direction in which the line L extends on the outer peripheral surface of the shaft portion 10. Therefore, there is no possibility that the line L will bite into a small groove that may be formed by the dividing surface P on the outer peripheral surface of the shaft portion 10. Therefore, the spool S becomes easy to use.

Further, in the embodiment, the first member S1 and the second member S2 are made of resin and have the same shape as each other. Therefore, both members S1 and S2 can be molded using the same mold, which simplifies manufacturing.

Further, in the embodiment, the rod member 20 is provided so that the rod member 20 can be changed from the first state in which a part of the line L is separated from the outer peripheral surface of the shaft portion 10 to the second state in which the line L is displaced so as to loosen the line L. Therefore, when the first member S1 and the second member S2 are separated from each other and the line L is shifted along the axial direction, if the rod member 20 is in the second state, the line L is loose and therefore in the axial direction. It becomes easy to shift along. That is, it becomes easier to remove the line L wound around the spool S from the spool S.

Further, in the embodiment, the rod member 20 can be easily changed between the first state and the second state by rotating the rod member 20 with the length direction thereof as the rotation axis 24 in the arrangement portion D.

Further, in the embodiment, since the metal rod R provided along the rod member 20 is further provided so as to reinforce the rod member 20, the rod member 20 is damaged by the tension of the line L wound around the shaft portion 10. There is no fear.

(Modified example of the embodiment)
In the embodiment, the shaft portion 10 is divided into a first portion 11 and a second portion 12 by one dividing surface P along the axial direction, but the present invention is not limited to this. For example, as shown in FIG. 5, the shaft portion 10 includes two first portions 11a and 11b included in the first member S1 by a split surface P1 parallel to the left-right direction and a split surface P2 parallel to the vertical direction. The two second parts 12a and 12b included in the second member S2 may be divided into four parts.

Further, as shown in FIG. 5, the through holes h1 and h2 of both flanges F1 and F2 are formed long so as to extend from the radial inside to the outside of the shaft portion 10, and penetrate both end portions 21 and 22 of the rod member 20. The rod member 20 may be slid in the holes h1 and h2, that is, the rod member 20 may be slid along the radial direction. In such a configuration, the state where the rod member 20 is radially outside the through holes h1 and h2 is the first state, and the state where the rod member 20 is radially inside the through holes h1 and h2 is the second state. For example, the line L can be loosened in the second state as compared with the first state.

Further, the first state and the second state of the spool S are not limited to this, and the rod member 20 is displaced so that the contact portion that was in contact with the line L of the rod member 20 in the first state does not come into contact with the line L. Since the line L may be loosened in the second state as compared with the first state, the line L may be loosened so that the rod member 20 can be removed from the arrangement portion D, for example. For example, the rod member 20 may be pulled out from the arrangement portion D, and the pulled out state may be set as the second state.

(Other embodiments)
In the above embodiment, the spool S is used by being attached to an electric or manual winder, but the spool S is not limited to this, and may be used by being attached to a reel, for example.

Further, in the above-described embodiment, the shaft portion 10 has a cylindrical shape, but the shape is not limited to this, and any shape may be used as long as the line L can be wound.

Further, in the above embodiment, in order to arrange the rod member 20 in the shaft portion 10, a gap 13 is provided in which the first portion 11 and the second portion 12 are separated from each other, but the configuration is such that the rod member 20 can be arranged. The gap 13 is not essential. For example, the arrangement portion D may be formed by providing a groove or the like at an arbitrary position on the outer peripheral surface of the shaft portion 10.

Further, in the above-described embodiment, the shaft portion 10 is divided by a dividing surface P parallel to the axial direction thereof, but the method of dividing the shaft portion 10 is not limited to this, and for example, the dividing surface P is divided. When viewed from the left-right direction or the up-down direction, the angle may be inclined by θ from the axial direction (in the above embodiment, θ = 0 °). However, from the viewpoint of preventing the line L from biting into the groove that can be formed on the outer peripheral surface of the shaft portion 10 by the dividing surface P, θ is the direction in which the line L extends on the dividing surface P and the outer peripheral surface (the line L is It is preferable to set it so that it is not parallel to the winding direction). That is, assuming that the angle formed by the direction in which the line L extends and the axial direction when viewed from the left-right direction or the vertical direction is θ _L (that is, if the line L extends perpendicular to the axial direction, θ _L = 90 °). ), It is preferable to set θ in the range of θ <θ _L.

Further, in the above embodiment, the spool S includes the rod member 20, but the rod member 20 is not essential. When the spool S does not include the rod member 20, the size of the diameter of the shaft portion 10 can be changed, and the second state is a state in which the size of the diameter of the shaft portion 10 is smaller than that of the first state. May be good. When the diameter of the shaft portion 10 becomes smaller, the line L wound around the spool S becomes loose, so that it becomes easy to remove the line L from the spool S.
