Description

  The present invention relates to a handle assembly, and more particularly to a fishing reel handle assembly that is non-rotatably attached to the tip of a handle shaft of a fishing reel.

  A handle assembly is fixed to the tip of a handle shaft of a fishing reel such as a spinning reel or a dual-bearing reel. The handle assembly includes a handle arm that is non-rotatably attached to the tip of the handle shaft, a handle shaft that is fixed to the tip of the handle arm, and a handle handle that is rotatably attached to the handle shaft.

  Such a handle arm is known, for example, made of a lightweight material such as a synthetic resin and embedded with a box-shaped body made of a highly rigid metal plate (see, for example, Patent Document 1). Here, weight reduction can be achieved by forming the handle arm from a synthetic resin, and the strength of the handle arm can be maintained high by embedding a box-shaped body made of a metal plate separate from the handle arm.

Japanese Utility Model Publication No. 51-64790

  The conventional handle arm is made of a lightweight synthetic resin, but it is conceivable to use a fiber reinforced resin in order to further reduce the weight. However, if the handle arm is formed of fiber reinforced resin, sufficient strength may not be obtained especially in the direction in which the fiber reinforced resin is laminated (handle axis direction). May be damaged. Therefore, it is conceivable to embed a box-shaped body made of a metal plate separate from the handle arm as in the case of a conventional handle arm. In this case, a process for burying the box-shaped body is necessary, and in general, In particular, it is technically difficult to embed a metal member in a fiber reinforced resin.

  An object of the present invention is to maintain a high strength in the handle shaft direction while reducing the weight of a handle arm in a fishing reel handle assembly.

  A fishing reel handle assembly according to a first aspect of the present invention is a handle assembly that is non-rotatably attached to a tip of a fishing reel handle shaft, and includes a handle arm, a handle shaft, and a handle handle. Yes. The handle arm is non-rotatably attached to the tip of the handle shaft, extends in a direction crossing the handle shaft, and is formed by laminating a plurality of prepregs, and the surface of the body portion to which the handle handle is attached and its surface It has a concavo-convex portion formed so as to be convex or concave on at least one of the back surface on the opposite side. The handle shaft is fixed to the tip of the handle arm and is disposed along the handle shaft. The handle handle is rotatably supported on the handle shaft.

  In this handle assembly, the handle arm has a convex shape on at least one of a main body portion formed by stacking a plurality of prepregs extending in a direction intersecting the handle shaft, and the back surface of the main body portion and the opposite side. Or it has the uneven | corrugated | grooved part formed so that it might become concave shape. Here, since the main body portion of the handle arm is formed by laminating a plurality of prepregs, the handle arm can be reduced in weight, and further, on the front surface of the main body portion of the handle arm or the back surface on the opposite side. Since the concavo-convex portion is formed, the section modulus in the longitudinal direction of the handle arm can be increased, and the strength in the handle shaft direction can be maintained high. Therefore, even if a large force acts on the handle arm in the handle axial direction, the handle arm can be prevented from being damaged. Furthermore, there is no need to embed a metal member in the handle arm as in the prior art.

  The main body portion is formed by laminating such that the fiber direction of at least one prepreg among the plurality of prepregs is different from the fiber direction of other prepregs other than one prepreg among the plurality of prepregs. In this case, since the fiber direction of at least one prepreg is laminated so as to be different from the fiber direction of other prepregs, the fiber direction of other prepregs is compared to the case where the fiber directions of all prepregs are the same direction. It is possible to further increase the strength of the main body against a load in a direction parallel to.

  Furthermore, the main body is formed by laminating so that the fiber direction of at least one prepreg among the plurality of prepregs faces in a direction intersecting so as not to be orthogonal to the longitudinal direction. In this case, since the fiber direction of the prepreg is laminated so as to face the X direction intersecting with the longitudinal direction of the main body, the strength against the force (torsional load) acting on the handle arm can be increased by rotating the handle. it can.

  The handle assembly according to a second aspect of the present invention is the handle assembly according to the first aspect, wherein at least one of the plurality of prepregs is a UD sheet having a single fiber direction. In this case, even when a UD sheet having a relatively low strength is used, lamination is performed such that the fiber direction of at least one UD sheet is different from the fiber direction of other UD sheets, or the fiber direction of the UD sheet is the longitudinal direction of the main body. The strength of the main body can be maintained high by stacking so as to face the X direction intersecting the direction.

  A handle assembly according to a third aspect of the present invention is the handle assembly according to the first or second aspect, wherein at least one of the plurality of prepregs is a cross prepreg in which the fiber directions are orthogonal to each other. The main body is formed by laminating so that one fiber direction of the cross prepreg faces in the longitudinal direction. In this case, the strength in the handle shaft direction can be further increased by laminating the cross prepreg so that one fiber direction is the longitudinal direction of the main body.

  The handle assembly according to a fourth aspect of the invention is the handle assembly according to any one of the first to third aspects, wherein at least one of the plurality of prepregs is a cross prepreg whose fiber directions are orthogonal to each other. The main body is formed by laminating so that the cross prepreg is positioned on the outermost surface. In this case, by laminating the cross prepregs in which the fiber directions are orthogonal to each other so as to be positioned on the outermost surface, it is possible to suppress the cracks from spreading in the fiber direction at the time of collision or dropping.

  The handle assembly according to a fifth aspect of the present invention is the handle assembly according to any one of the first to fourth aspects, wherein the concavo-convex portion is a convex portion formed to protrude from the surface of the main body portion. In this case, since the concavo-convex portion is a convex portion formed on the surface of the main body (the outer surface of the main body), the fishing line is less likely to get entangled with the handle arm, and foreign matters such as dust, sand and salt are It becomes difficult to collect on the surface of

  The handle assembly according to a sixth aspect of the present invention is the handle assembly according to any one of the first to fifth aspects, wherein the concavo-convex portion is a concave formed on the back surface of the main body portion. In this case, since the concavo-convex portion is a concave portion formed on the back surface of the main body portion (the inner surface of the main body portion), the fishing line is not easily entangled with the concave portion because the concave portion is not exposed to the outside.

  The handle assembly according to a seventh aspect of the present invention is the handle assembly according to any one of the first to sixth aspects, wherein the concavo-convex portion is formed to have a shape substantially similar to the outer shape of the main body portion. In this case, since the concavo-convex part is formed so as to have a shape substantially similar to the outer shape of the main body, for example, by hot pressing a flat handle arm, the outer shape of the main body is substantially similar. It is possible to easily form the uneven portion.

  The handle assembly according to an eighth aspect of the present invention is the handle assembly according to the seventh aspect, wherein the uneven portion is formed by hot pressing. In this case, it is easy to form the uneven portion.

  The handle assembly according to a ninth aspect is the handle assembly according to any one of the first to eighth aspects, wherein the prepreg is a carbon prepreg. In this case, it is possible to reduce the weight of the handle arm and to obtain a high-quality appearance design using carbon.

  According to the present invention, in the handle assembly of a fishing reel, the handle arm extends in a direction intersecting the handle shaft, and is formed by laminating a plurality of prepregs, the surface of the main body, and the opposite side thereof. Since at least one of the back surfaces of the handle has a concavo-convex portion formed so as to be convex or concave, the strength in the handle shaft direction can be maintained high while reducing the weight of the handle arm. .

  Next, the process for manufacturing the handle arm 21 will be described with reference to the flowchart of FIG.

  First, in step S1, a large carbon prepreg 30 serving as a base material capable of manufacturing a plurality of handle arms 21 is prepared. Next, in step S2, eleven UD sheets 31 and two carbon cloths 32 are laminated so that the fiber direction is the direction shown in FIG. Next, in step S <b> 3, a plurality of carbon prepregs 30 are integrated by performing hot pressing, and a convex portion 21 b and a concave portion 21 c are formed in the center portion of the handle arm 21. Next, in step S4, two through holes 21d, a non-circular hole 21e, and a through hole 21f are formed by cutting, and the outer shapes of the plurality of handle arms 21 are cut out. Next, in step S5, polishing operations such as buffing and barrel polishing are performed. Next, in step S6, a painting operation for applying a glossy transparent paint is performed. At this time, in order to mask the non-circular hole 21e of the handle arm 21, the painting operation is performed with the handle arm 21 attached to the masking jig 40 shown in FIG. As shown in FIG. 10, the masking jig 40 includes a plate-like pedestal portion 41 to which the inner surface of the handle arm 21 is attached, and a non-circular hole 21e of the handle arm 21 that is erected on the pedestal portion 41 and is inserted into the handle arm 21.

And a cover portion 43 to be mounted. The outer diameter A of the contact portion 43b of the cover portion 43 that contacts the handle arm 21 when the cover portion 43 is attached to the protruding portion 42 is formed to be larger than the maximum inner diameter of the non-circular hole 21e. As shown, the nut member 24 is formed to be larger than the outer diameter B of the contact portion 24b of the nut member 24 that contacts the handle arm 21 when the nut member 24 is attached to the male screw portion 20b of the handle shaft 20. Here, since the outer diameter A of the contact portion 43b of the cover portion 43 is formed to be larger than the outer diameter B of the contact portion 24b of the nut member 24, the handle arm 21 with which the contact portion 24b of the nut member 24 comes into contact. The outer surface of the film is reliably masked, and the paint is not applied to this part. Accordingly, even if the nut member 24 is strongly tightened and the nut member 24 is strongly pressed against the painted carbon handle arm 21, the paint is applied to the outer surface of the handle arm 21 where the contact portion 24b of the nut member 24 contacts. This prevents the paint from peeling off from this portion. In step S7, a printing operation for printing characters such as a reel model number and a manufacturer name is performed.

And a formed recess 21c. Here, since the main body 21a of the handle arm 21 is formed by laminating a plurality of carbon prepregs 30, the weight of the handle arm 21 can be reduced, and the surface of the main body 21a of the handle arm 21 can be reduced. Since the convex portion 21b and the concave portion 21c are formed on the (outer surface) and the back surface (inner surface) of the main body portion 21a, the longitudinal section coefficient of the handle arm 21 can be increased, and the handle shaft 20 direction (handle arm) 21 strength in the orthogonal direction) can be maintained high. Therefore, even if a large force acts on the handle arm 21 in the direction of the handle shaft 20, the handle arm 21 can be prevented from being damaged. Further, it is not necessary to embed a metal member in the handle arm 21 as in the prior art, and therefore a high-quality appearance design with carbon can be obtained.
