Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a component assembly, and more particularly, to a fishing reel component assembly in which at least a part of a surface is constituted by a three-dimensional curved surface.
[0002]
[Prior art]
For fishing reels such as spinning reels and double-bearing reels, a part assembly composed of a three-dimensional curved surface is often used in consideration of design and function. For example, a reel body (an example of a component assembly) of a dual-bearing reel or a spinning reel is assembled by a plurality of components that are configured by a three-dimensional curved surface. When manufacturing a part composed of a three-dimensional curved surface, if the three-dimensional curved surface is formed by machining, the processing becomes complicated and the processing cost increases. Therefore, it is usually manufactured by a mold forming method using a mold. For example, in the case of a synthetic resin part, it is manufactured by a molding method such as injection molding, and in the case of a metal part, it is manufactured by a die molding method such as die casting.
[0003]
When a part assembly is configured by abutting two parts having different mold dividing directions at a three-dimensional curved surface portion, conventionally, a butting surface is arranged along the mold drawing direction of any part. For this reason, depending on the shape of the three-dimensional curved surface of the abutting portion, the edge on one surface side may be an extremely acute angle, and the edge on the other surface side may be an extremely obtuse angle. For example, when a reel body is configured by abutting a side cover of a conventional dual-bearing reel with a front cover that also serves as a thumb rest, the abutting surface is often arranged along the side cover removal direction. For this reason, the edge on the surface side of the abutting portion of the front cover formed by the mold divided before and after the reel becomes an acute angle, and the side cover formed by the mold divided right and left of the reel becomes an obtuse angle. The mold is divided at the edge portion in order to keep the sharp edge in a pointed state so as not to be blurred. If it does in this way, components can be taken out smoothly from two divided types.
[0004]
[Problems to be solved by the invention]
In the conventional configuration, since the mold is divided at an acute edge, burrs are likely to occur at the tip of the acute edge. When a burr occurs, you feel uncomfortable when your palm or finger touches the boundary. Therefore, when a burr | flash generate | occur | produces, the deburring operation | work which removes a burr | flash is performed. However, since the edge has an acute angle, it is difficult to distinguish between the burr and the edge, and the deburring operation may cause the edges other than the burr to be cut. If the edges other than the burrs are cut away, there will be too much gap at the abutting part, and the gap will be conspicuous, resulting in an appearance problem.
[0005]
An object of the present invention is to provide a component assembly in which a burr can be easily identified even if a burr occurs at the edge of a butt portion.
[0006]
[Means for Solving the Problems]
A fishing reel component assembly according to a first aspect of the present invention is an assembly in which at least a part of a surface is formed of a three-dimensional curved surface, and includes a first surface component and a second surface component. The first surface part is a molded part that constitutes a part of a three-dimensional curved surface. The second surface part is a molded part that is abutted with the first surface part and arranged so that the surface is flush with the first surface part on a three-dimensional curved surface. In the first surface component and the second surface component, the angle formed by the edge of the butted surface and each surface is in the range of 70 to 110 degrees on the first surface component side, and is in the range of 110 to 70 degrees on the second surface component side. It is. Further, an escape portion is formed at an acute angle on the inner surface side of the abutting surface.
[0007]
In this component assembly, the angle formed between the butt surface and each surface is maintained at an angle that is relatively close to 90 degrees of 70 to 110 degrees. Therefore, in any surface component, it occurs at the edge between the surface and the butt surface. The burr is easy to identify against the edge. For this reason, even if burrs occur, it becomes easy to remove only the burrs.
[0008]
A fishing reel component assembly according to a second aspect of the present invention is the assembly according to the first aspect, wherein the first surface component is a front cover that also serves as a thumb rest disposed at the front of the reel body of the dual-bearing reel, The second surface part is a side cover disposed on the side opposite to the handle mounting side of the reel body. In this case, since burrs are easily removed, it is difficult to feel uncomfortable even if a finger touches the abutting portion between the front cover and the side cover that also serves as a thumb rest.
[0009]
The fishing reel component assembly according to a third aspect of the present invention is the assembly according to the second aspect, wherein the first surface component is formed by a die divided in the front-rear direction of the reel body, and the second surface component is a reel. Molded by a mold divided in the left-right direction of the main body. In this case, it becomes easy to deburr the two surface parts formed using the molds divided in different directions.
[0010]
A fishing reel component assembly according to a fourth aspect of the present invention is the assembly according to any one of the first to third aspects, wherein both surface components are injection-molded synthetic resin molded products. In this case, it becomes easy to deburr the synthetic resin molded product.
[0011]
A fishing reel component assembly according to a fifth aspect of the present invention is the assembly according to any one of the first to third aspects, wherein both surface parts are die-cast metal molded products. In this case, it becomes easy to deburr the metal molded product.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A dual-bearing reel employing an embodiment of the present invention is a low profile type reel for bait casting, as shown in FIGS. The dual-bearing reel includes a reel body 1, a handle assembly 2 for rotating a spool disposed on the side of the reel body 1, and a spool for spooling a thread that is rotatably and detachably mounted inside the reel body 1. 4 is provided. On the reel body 1 side of the handle assembly 2, a star drag 3 for drag adjustment is provided.
[0013]
As shown in FIGS. 1 to 5, the reel unit 1 includes a frame 5, side covers 6 a and 6 b (an example of second surface parts) mounted on both sides of the frame 5, and a front of the frame 5. And a cover 7 (an example of a first surface component). The outer shape of the reel body 1 has a shape with the front side squeezed as a whole.
[0014]
The frame 5 is made of metal obtained by die-casting an aluminum alloy, for example. The frame 5 has a pair of left and right side plates 8a and 8b and two connecting members 9a and 9b that connect the side plates 8a and 8b. The side plates 8a and 8b are generally oval plate-like members, and have edge portions 8c and 8d that protrude outwardly at the edge portions, respectively. The edge portions of the side covers 6a and 6b are abutted with the ends of the edge portions 8c and 8d without any step. The connecting members 9a and 9b connect the side plates 8a and 8b to the front and lower parts of the reel, respectively. The front connecting member 9a has a stepped portion 9c formed so as to be lower than the front cover 7 is attached. The front cover 7 is mounted flush with the frame 5 by the step 9c. A heel mounting leg 10 extending in the front-rear direction is integrally formed with the lower connecting portion 9b.
[0015]
The side cover 6a is a synthetic resin-molded member that is curved outwardly so as to cover the outside of the side plate 8a with a space. The outer surface of the side cover 6a has a smooth three-dimensional curved surface so as not to cause a sense of incongruity when palming. The side cover 6a is swingably and detachably attached to the rear lower part of the side plate 8a, and opens and closes with respect to the side plate 8a. An operation unit 15 for opening / closing operation is provided at the center of the side cover 6a. An adjustment unit 16 for adjusting the braking force of a centrifugal braking device for spool braking (not shown) is provided at the center of the operation unit 15.
[0016]
The side cover 6b is a molded member made of synthetic resin that is curved outward so as to cover the outside of the side plate 8b with a space. The side cover 6b is fixed to the side plate 8b with screws. The side covers 6a and 6b are manufactured by, for example, injection molding using a mold divided in the left-right direction of the reel.
[0017]
An abutting portion 20 for abutting the front cover 7 flush with each other is formed on the front upper portions of the side covers 6a and 6b. As shown in FIG. 6, the butt surface 20a is three-dimensional so that the angle α formed by the edges of the butt surface 20a of the butt portion 20 and the surfaces (tangents) of the side covers 6a and 6b is in the range of 110 to 70 degrees. It is formed so as to be twisted. When the angle α is set in such a range, even when burrs are generated at the edge when the side plate 6a is molded, it is easy to distinguish the burrs from the edges, and it is easy to reliably remove only the burrs.
[0018]
Further, a relief portion 20b is formed at an acute angle on the inner surface side of the abutting surface 20a. If such a relief part 20b is formed, when the side covers 6a and 6b are manufactured by a mold, it becomes easy to correct the butting surface of the mold. That is, if this relief part 20b is not formed, when it is necessary to correct the mold, there is a case where the abutting surface with other members is affected or there is an interference with a member built in the mold. However, by providing the relief portion 20b, these inconveniences are eliminated and the mold can be easily corrected.
[0019]
The front cover 7 is a molded member made of synthetic resin, and has a three-dimensional curved surface that is continuous with the surface at the abutting portion with the side covers 6a and 6b. The front cover 7 is manufactured by, for example, injection molding using a mold divided in the front-rear direction of the reel. The front cover 7 also serves as a thumb rest, and is fixed to the side plates 8a and 8b with screws. The edge portion 21 of the front cover 7 is configured by a three-dimensional curve, and is abutted against the side plates 8a and 8b and the connecting member 9a of the frame 5 and the abutting portion 20 of the side covers 6a and 6b. As shown in FIG. 6, the butt surface 21 a is three-dimensional so that the angle β formed by the edge between the butt surface 21 a of the edge 21 of the front cover 7 and the surface of the front cover 7 is in the range of 70 to 110 degrees. It is formed to be twisted. Within such a range, even if burrs occur at the edge when the front cover 7 is molded, it is easy to distinguish the burrs from the edges, and it is easy to reliably remove only the burrs. Further, a relief portion 21b similar to the side cover 6a is formed at an acute angle on the inner surface side of the abutting surface 21a.
[0020]
The spool 4 is rotatably supported by the reel body 1 and can be detached from the side plate 8a side when the side cover 6a is opened.
[0021]
In the dual-bearing reel having such a configuration, the front cover 7 and the side plate 6a are formed by a continuous three-dimensional curved surface, so that it is difficult for the palm to feel uncomfortable when palming. In addition, since the abutting surfaces 20 and 21 of the front cover 7 and the side covers 6a and 6b are three-dimensionally formed so as to be relatively close to 90 degrees, even if burrs occur during molding, burrs and edges are formed. It becomes easy to identify, and it is easy to remove only burrs reliably.
