Description

TECHNICAL FIELD The present invention relates to a fishing reel, and more particularly to a fishing reel that includes an abutting member attached to the reel body.

In recent fishing reels, the reel body has been made into a monocoque structure in order to make the reel smaller and lighter. In such a structure, an opening is formed so that the components inside the reel body can be easily accessed, and a cap, cover member, etc. (hereinafter collectively referred to as an abutment member) is installed to close the opening. Installation is being done.

When attaching the abutting member to the main body, the abutting member is fixed by screwing or the like with a sealing member interposed between the two so as to be waterproof and dustproof. The sealing member is made of an elastic material such as rubber, and when assembling a fishing reel, an operator attaches the abutting member to the reel body via the sealing member.
By the way, a certain degree of skill is required to attach the abutting member by interposing the sealing member between the reel body and the abutting member. For example, a structure in which a rear cap is attached to the rear opening of the reel body is known as a spinning reel, but since the opposing edges of the rear cap and the reel body that abut each other are curved, the sealing member can be stably inserted. difficult to do.

Therefore, in Patent Document 1, in order to stably interpose a sealing member between the rear cap and the reel body of a spinning reel, a protrusion with a substantially triangular cross section (tapered shape) is provided on the edge of the rear cap. A configuration is disclosed in which the sealing member is formed in advance and the two members are joined by fitting the sealing member into the protrusion (see FIG. 8, which will be described later).
According to such a configuration, the seal member is prevented from being displaced or deformed, so that the seal member is held in an appropriate position and can exhibit waterproof and dustproof functions.

JP2017-108719

As mentioned above, it is necessary to separately attach a sealing member between the abutting member and the reel body, but the part where the sealing member is attached has a three-dimensional and complicated shape. If so, steps such as bending the seal member to match the shape of the installation location are required. For this reason, the installation work is not easy, takes time, and requires skill. In other words, on curved parts, it is difficult to install the sealing member in a uniform manner over the entire area, which may cause variations between products such as the sealing member protruding, and rework, etc. Problems such as discarding the seal member and rear cap have arisen.

The present invention has been made in view of the above-mentioned problems, and provides a fishing reel in which an abutment member is attached to the reel body, with stable waterproof and dustproof functions between the two, easily and at low cost. The purpose of the present invention is to provide a fishing reel that can achieve the desired performance.

In order to achieve the above object, the present invention provides a fishing reel equipped with an abutting member that is fixed against a reel body, in which an elastic A sealing member is interposed therebetween, and the sealing member is characterized in that it is integrally molded at the joint portion of the abutment member or the joint portion of the reel body.

The fishing reel according to the present invention includes an abutting member that is abutted against and fixed to the reel body. The reel main body and the abutting member are separate members, and a sealing member (packing) is interposed between the two members so that the reel body and the abutting member are waterproof and dustproof when they are abutted and fixed. The sealing member is integrally molded in advance at the joint of the contact member or the joint of the reel body, so it is not necessary to interpose another sealing member formed of a ring-shaped rubber member or the like, as in the past. However, the work of abutting and fixing the abutting member to the reel body is unnecessary. Therefore, when assembling the reel main body, there are no variations between products, there is no need to redo the work, and there are no problems such as discarding the sealing member or the contact member.

According to the present invention, it is possible to obtain a fishing reel that can stably exhibit waterproof and dustproof functions between the abutting member and the reel main body when the abutting member is attached to the reel body easily and at low cost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fishing reel according to the present invention will be specifically described with reference to the drawings. In the embodiment described below, a spinning reel is used as a fishing reel, and a rear cap is exemplified as a member attached to the reel body.

1 and 2 are diagrams showing an example of the configuration of a spinning reel according to this embodiment. In these figures, the directions indicated by the arrows are defined as the front-rear direction and the up-down direction, and the direction perpendicular to the page is defined as the width direction (left side in FIG. 1 and right side in FIG. 2).

First, an overview of the overall configuration of the spinning reel will be explained.
A reel body (hereinafter also referred to as the main body) 2 of the spinning reel 1 is formed with leg portions 3 that are attached to a fishing rod. A handle shaft is rotatably supported by the main body 2 via a bearing, and a handle 4 that is operated for winding is attached to an end of the handle shaft. Further, a known driving force transmission mechanism is connected to the handle shaft, and as the handle 4 is rotated, the rotor 10 is rotationally driven, and the spool 5 is moved back and forth via a known oscillating mechanism. It looks like this.

The spool 5 has a fishing line winding trunk 5a around which the fishing line is wound, and a front flange 5b and a rear flange (skirt) 5c that define the amount of line winding of the fishing line winding trunk 5a in the front-rear direction. are doing. Further, a pair of support arms 11 and 12 are formed on the rotor 10 so as to extend forward in the axial direction and face each other at approximately 180° intervals, and the spool 5 is located between the pair of support arms. It is driven back and forth. A bail support member 14, 15 is supported at the tip of each support arm 11, 12 so as to be rotatable between a fishing line winding position and a fishing line releasing position. Further, a base end portion of a semi-annular bail 17 is attached to each of the bail support members 14 and 15, and the bail 17 is rotatable together with the bail support members 14 and 15. A fishing line guide device 20 for guiding the fishing line to the spool is disposed at the tip of one bail support member 15.

1 and 2 show a fishing line winding state, and when the handle 4 is rotated in this state, the rotor 10 is rotationally driven via the driving force transmission mechanism, and the spool 5 is moved back and forth via the oscillating mechanism. It is driven back and forth. Thereby, the fishing line is evenly wound around the fishing line winding body 5a of the spool 5 via the fishing line guide device 20 of the bail support member 15 that rotates together with the rotor 10. When the bail 17 is rotated from the fishing line winding state shown in the figure to the fishing line release position (rotated in the direction of the arrow) together with the rotation of the bail support members 14 and 15, the bail 17 is wound around the spool 5. The fishing line is in a released state (not shown). Further, after releasing the fishing line in this fishing line releasing state, when the bail 17 is rotated from the fishing line releasing position to the fishing line winding position, the fishing line is picked up by the bail 17 and guided to the fishing line guide device 20, and the fishing line is The thread will be wound up.

The main body 2 of the spinning reel described above has a monocoque structure, and is designed to be small and lightweight. For this reason, the above-mentioned driving force transmission mechanism and oscillating mechanism, which are internal parts within the main body 2, become difficult to access from the outside, so it is necessary to form an opening, and to close the opening. It is necessary to provide a member (cap, cover, etc., collectively referred to as "abutting member" in the present invention) for this purpose. When such an abutting member is provided on the main body 2, it is necessary to provide a sealing member (packing) between the two for waterproofing and dustproofing functions.

In the spinning reel of this embodiment, an opening is formed at the rear end of the main body 2 to facilitate access to the oscillating mechanism, and a rear cap 30, which is an abutting member, is attached to this part to close the opening. That's what I do. The rear cap 30 is removably fixed to the main body 2 by fixing means such as screws (not shown). In this case, an elastic sealing member is interposed at the joint between the rear cap 30 and the main body 2 (the end edges of each member), as will be described later.

Here, a conventional technique in which a seal member is interposed between the rear cap and the main body will be described with reference to FIG. 8.

Conventionally, when the sealing member 100 made of an elastic material such as rubber is interposed between the joint 30A of the rear cap 30 and the joint 2A of the main body 2, the joint 30A of the rear cap 30 has a cross section approximately A triangular (tapered) protrusion 30a is formed, and the seal member 100 is fitted into the protrusion 30a to join the rear cap 30 to the main body 2. Forming the protrusion 30a in this way prevents the seal member 100 from shifting or deforming, so that the seal member is held in an appropriate position and can exhibit waterproof and dustproof functions. In other words, due to its structure, there is a possibility that gaps may occur between the rear cap 30 and the seal member 100 (boundary A) and between the seal member 100 and the main body 2 (boundary B), so fastening with screws is not possible. Waterproofness is ensured by applying force and fitting the sealing member into the projection 30a described above.

However, since the joint portion where the rear cap 30 and the main body 20 face each other has a three-dimensional and complex shape that is displaced in the front-rear direction, vertical direction, and width direction (complex shape that is displaced in three dimensions), it is difficult for the operator to This requires steps such as bending the seal member 100 to match the shape of the attachment position and fitting the seal member 100 into the protrusion 30a. For this reason, it is difficult to install the seal member 100 in a uniform manner over the entire curved portion, and the seal member protrudes or there are variations between products, resulting in rework, etc. 100 and the rear cap 30 are discarded.

In the present invention, when an elastic sealing member is interposed between the main body 2 and the rear cap 30, the sealing member is integrally molded at the joint of the contact member or the joint of the main body. There is. In other words, by integrally molding the sealing member with the contact member and the main body, waterproof and dustproof properties are improved, and the conventional work of bending the sealing member or inserting it into the protrusion is unnecessary, making it easier. It is configured so that it can be assembled.

The specific structure will be explained below.
FIG. 3 is a diagram showing a first embodiment of the seal member, and is a cross-sectional view in which the seal member 50 is interposed between the joint portion 30A of the rear cap 30 and the joint portion 2A of the main body 2. The joint portion 30A and the joint portion 2A in this embodiment are flat surfaces that face each other and are joined.

The sealing member 50 is integrally molded with the rear cap by two-color molding over the entire circumference of the joint portion 30A of the rear cap 30. Such two-color molding can be performed using a general two-color molding machine, and the base rear cap 30 is made of thermoplastic resin (for example, ABS, acrylic, polycarbonate, polybutylene terephthalate, polyamide, etc.). After integrally molding, the sealing member 50 is made of a flexible material (for example, a styrene-based, olefin-based, urethane-based, ester-based, or amide-based thermoplastic elastomer) for the joint portion 30A of the rear cap 30. Can be integrally molded.

The thickness T of the sealing member 30 is not particularly limited, but if it is about 0.4 to 1.0 mm, the sealing member can exhibit sufficient waterproofness and dustproofness without being damaged. In this way, with two-color molding, the boundary between the rear cap 30 and the seal member 50 is fused during the manufacturing process, making it possible to reduce the possibility of a gap as shown in FIG. 8 occurring. (The only gap is the boundary B), which can improve airtightness.

Furthermore, as described above, if the sealing member 50 is integrally formed with the rear cap 30 by two-color molding, even if the opening end surface of the rear cap 30 has a complicated shape that is displaced in three dimensions, the rear cap 30 can be simply molded. Sealing performance can be ensured simply by fixing it to the main body 2 (because the thickness can be made uniform and the sealing performance can be stabilized). That is, even if the sealing area is curved, the sealing member interposed between the two does not protrude or vary from product to product, so there is no increase in work effort or manufacturing costs. Further, the degree of freedom in designing the rear cap 30 can be improved, and the number of assembly steps can be reduced.

In the above configuration, it is preferable that the rear cap 30 and the main body 2 be made of a material that can be plated, and that the two-color molded seal member 50 be made of a material that cannot be plated. For example, when molding the main body 2 with resin, plating may be applied to give it a shiny appearance. However, if the seal member 50 is similarly plated, it may be damaged or deteriorated. There is a possibility that sufficient waterproofness and dustproofness cannot be achieved. For this reason, it is preferable that the seal member 50 be formed of a material that will not be plated even if the rear cap 30 is plated, such as a polyurethane thermoplastic elastomer.
As a result, parts other than the seal member 50 can be plated, and at the same time, it is possible to achieve both the appearance required for the rear cap 30 and the waterproof and dustproof properties required for the seal member 50.

Note that in the above configuration, the seal member 50 is integrally molded on the rear cap side, but it may be integrally molded on the main body side, or may be integrally molded on both. Further, the sealing member 50 may be formed to have a step 30A' on the surface of the rear cap 30, as shown in the cross-sectional view of FIG. It may be formed so that it is exposed in terms of appearance, or it may be formed so that it is exposed in terms of appearance.

4 and 5 are views showing a second embodiment of the sealing member, FIG. 4 is a view showing a rear cap, FIG. 5(a) is a sectional view at the position indicated by P1 in FIG. 4, and FIG. (b) is a sectional view at the position indicated by P2 in FIG. 4.

The rear cap 30 is attached to the opening at the rear end of the main body 2, and is also a part that exhibits design. The seal member 51 may be made invisible at the boundary between the rear cap 30 and the main body 2, or may be exposed, since the degree of freedom in design is increased by molding the seal member 51 in two colors. That is, the seal member 51 may be integrally molded so as to be exposed between the joint portion of the main body 2 and the joint portion of the rear cap 30. In this case, for example, as shown in FIG. 4, the exposed wall thickness T1 is made thinner at the exposed portion P1 on the upper end side, and as it curves downward from there, the exposed wall thickness is gradually increased to increase the appearance. (In the exposed portion P2 on the lower end side, the exposed wall thickness T2 is thicker than the wall thickness T1).

Even if the seal member 51 is exposed in a shape where the wall thickness changes in consideration of the appearance, by using two-color molding as described above, the wall thickness will not change unevenly in the attached state, and the waterproof property will be improved. , dust resistance is not impaired. Further, even if the rear cap has various shapes, it is possible to create a rear cap according to the shape, and it is possible to achieve both good appearance and waterproof and dustproof properties.

Regarding the shape of the sealing member 51 relative to the rear cap 30, as shown in FIG. Can be integrally molded. That is, as shown in FIG. 5, it is possible to form a convex part 30b along the joining direction in the joint part 30A of the rear cap 30, and to mold a concave seal member 51 in this convex part 30b. . In this case, when molding the rear cap 30, the height of the convex portion 30b is changed along the joining direction, and accordingly, the thickness T of the sealing member 51 is made uniform, and the thickness of the exposed portion is (T1, T2) can be easily changed.
In this way, it is possible to easily change the appearance while maintaining the thickness of the seal member 51.

FIG. 6 is a diagram showing a third embodiment of the sealing member, and is a partial sectional view of the rear cap.
In this embodiment, the joint between the rear cap 30 and the main body 2 is configured to have a labyrinth structure. Note that the labyrinth structure here means that the mutually opposing portions of the joint portion of both members are not a single surface but a composite surface, and the structure is such that each of the plurality of surfaces faces each other. For example, in the configuration shown in FIG. 6, the rear cap 30 has three joint surfaces 30d, 30e, and 30f formed along the joint direction in the joint region, and the main body 2 has three joint surfaces 30d, 30e, and Three bonding surfaces 2d, 2e, and 2f are formed along the bonding direction so as to face 30f.

When such a labyrinth structure is used, the waterproof and dustproof effects are enhanced, and furthermore, the rear cap 30 or the seal member 52 integrally molded on the main body 2 is placed in areas facing each other as a labyrinth structure along the joining direction. By integrally molding at least one part of the sealing member, the sealing member can be easily molded, and the waterproof and dustproof effects can be further enhanced.

In this embodiment, the seal member 52 is integrally formed on the joint surfaces 30e and 30f, which are the inner sides of the rear cap 30, so that the seal member 52 is not exposed. However, even if it is formed on the joint surface 30d and exposed. good.

FIG. 7 is a diagram showing a fourth embodiment of the sealing member, and is a partial cross-sectional view of the rear cap.
In this embodiment as well, the joint between the rear cap 30 and the main body 2 has a labyrinth structure, and the rear cap 30 has two joint surfaces 30g and 30h formed along the joint direction in the joint region. There is.

The joining surface may be a curved surface instead of a flat surface (curved surface 30h), and the sealing member may be integrally molded at multiple locations along the joining direction (sealing members 54, 55).
By performing two-color molding in this way, it becomes possible to freely design the shapes of the joints and sealing members. In other words, as in this embodiment, a structure in which the joint part has a labyrinth structure and seal members are molded in multiple places in the joint region can be easily achieved, and thereby it is possible to further improve waterproofness and dustproofness. Become.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified in various ways.
In the embodiment described above, the sealing member and the contact member (rear cap 30) are integrally molded by two-color molding, but other than two-color molding, they may be integrally molded by adhesive, thermal welding, or the like.

In addition to the above-mentioned rear cap, the present invention can be applied to various openings formed in the main body 2, members that close the openings, or members that cover the main body 2 (abutting members). It is possible. For example, it may be applied to a cover body attached to the main body on the side opposite to the handle, or it can be applied to various contact members, such as provided on cover bodies on both sides of the main body of a double bearing type reel. Furthermore, the thickness, shape, molding position, etc. of the sealing member can be modified as appropriate depending on the configuration of the abutting member.
