Description

  The present invention relates to a structure of a fishing spinning reel that is excellent in handle operation smoothness.

  As shown schematically in FIG. 1, the spinning reel for fishing is rotated to a reel body 11 mounted on a fishing rod, a handle 12 rotatably mounted on the reel body 11, and a front portion of the reel body. It is composed of a number of movable parts such as a fishing line guiding rotor 13 that is mounted, a spool 14 that moves back and forth for winding the fishing line, and a bale 15 that controls the movement of the fishing line. Yes.

  As described in detail in Patent Documents 1 and 2, the current fishing spinning reel has been regarded as a problem in particular, how to wind the fishing line to a uniform thickness on the reciprocating spool 14. It is a problem. In order to achieve this, a slider fixed to the spool shaft 17 that engages with the protrusion 20 of the oscillating gear 19 among the sliding mechanism (oscillating mechanism) 16 that converts the rotation of the handle into the reciprocating motion of the spool. Various proposals have been made for the shape of the groove 21 provided in the (oscillate slider) 18, and the uniformity of the winding of the fishing line has been improved thereby.

  However, the problem with the current fishing spinning reel is not only that, but there is also a problem that the smoothness of operation is not yet sufficient. In order for the user to feel that the operation of the reel is smooth, it is required that the movable parts such as the rotor, the spool, the handle gear and the like smoothly rotate and reciprocate without backlash. In particular, the spool has its own weight and reciprocates, so it becomes easy to feel discontinuity of operation when the direction of movement of the spool is reversed, and a large tension is required when winding the fishing line. For this reason, there is a problem that the operation before and after becomes non-target and backlash occurs to make the operation feel discontinuous or abnormal noise is generated.

  An object of the present invention is to provide a fishing spinning reel that solves the above-described problem of operability of the conventional fishing spinning reel and improves the smoothness of reel operation, particularly handle operation.

  As shown in FIG. 1, when the handle 12 is rotated, the rotor 13 rotates, and in conjunction with the rotation, the spool 14 reciprocates back and forth in order to evenly wind the fishing line around the spool. . Although an oscillating mechanism 16 is provided as a mechanism for converting the rotational movement of the handle into a reciprocating movement of the spool 14, in the present invention, an intermediate gear for transmitting the rotation of the handle 12 to the oscillating gear 18 is made of resin. Is designed to use Subaru gear.

  That is, the present invention provides the following fishing spinning reels.

A reel body, a handle rotatably mounted on the reel body, a fishing line guide rotor rotatably mounted on the front of the reel body, and before and after winding the fishing line disposed on the front of the rotor A fishing spinning reel comprising a reciprocating spool and a bale for controlling the movement of a fishing line, wherein the fishing spinning reel has an oscillating mechanism for converting the rotation of the handle into the reciprocating movement of the spool. Prepare for the inside,
The oscillating mechanism is fitted to a first gear coupled to the shaft of the handle, a mechanism for converting the rotational movement of the handle into a reciprocating movement of the spool, and the oscillating gear for driving the converting mechanism; At least a second gear for transmitting rotation of the first gear to the oscillating gear;
A fishing spinning reel, wherein at least one of the first gear, the second gear, and the oscillating gear is a helical gear made of resin.

The fishing spinning reel of the present invention further includes a resin idle gear for transmitting the rotation of the second gear to the oscillating gear between the second gear and the oscillating gear. Also good.
In the fishing spinning reel of the present invention, the rotation shafts of the second gear and the idle gear are adjusted in the reel body, and the position of the axis of the rotation shaft is adjusted in the axial radial direction with respect to the reel body. It may be fixed with screws.

  The conversion mechanism includes a plate-like oscillating slider having an S-shaped hollow groove coupled to the other end of the spool shaft coupled to the spool and transmitting the reciprocating movement, and a side surface of the oscillating gear. And a post that fits into the groove and moves along the groove to convert the rotation of the oscillating gear into a reciprocating motion of the spool shaft.

  Further, in the fishing spinning reel of the present invention, the resin material may be at least one of POM (polyacetal), PA (polyamide), PPS (polyphenylene sulfite), and PEEK (polyether ether ketone).

  By using the oscillating mechanism configured as in the present invention, it is possible to provide a fishing spinning reel with excellent reel operation smoothness.

FIG. 1 is a cross-sectional view schematically showing an outline of the arrangement of components in a conventional fishing spinning reel. FIG. 2 is a perspective view schematically showing an oscillating mechanism according to an embodiment of the present invention. FIG. 3 is a schematic view of the oscillating mechanism according to the embodiment of the present invention viewed from the lateral direction.

  Embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiments described below.

  FIG. 2 is a perspective view schematically showing the arrangement of components of the oscillating mechanism 200 that converts the rotation of the handle into the reciprocating movement of the spool in the fishing spinning reel according to the embodiment of the present invention. FIG. 3 is a schematic view of this mechanism as seen from the side. The oscillating mechanism of the present invention will be described with reference to these drawings. A shaft (not shown) of the handle directly connected to the handle (not shown) is fixed to the shaft holder 201, and the first gear 202 fixed to the holder 201 rotates by turning the handle. The second rotating shaft 211 holds the second gear 212 and the idle gear 213, and the teeth of the second gear 212 are engaged with the teeth of the first gear 202, and the first gear 202 rotates with the rotation of the first gear. The second gear 212 rotates about the rotation shaft 211 in the opposite direction to the first gear. As shown in FIG. 3, the rotation shaft 211 is fixed to the reel body 230 with a screw 226 with an adjustment width in the axial radial direction, and the position of the axis of the rotation shaft 211 can be adjusted when the screw 226 is tightened. The idle gear 213 having a smaller radius than the second gear 212 also rotates in reverse in conjunction with the second gear 212. The teeth of the idle gear 213 are engaged with the teeth of the oscillation gear 221 having a large radius, and the rotation of the idle gear 213 decelerates and rotates the oscillation gear 221. In the embodiment shown in FIGS. 2 and 3, the second gear 212 and the idle gear 213 rotate integrally. However, they may be integrated, or each may be individually coupled to prevent rotation.

  The oscillating gear 221 is provided with a post 222 which is a protruding portion fixed thereto. This post 222 is fitted in an S-shaped groove 223 provided in the oscillating slider 224, and a main shaft 225 is fixed to the oscillating slider 224. With the rotation of the oscillating gear 221, the post 222 moves along the inside of the S-shaped groove 223, and the main shaft 225 reciprocates (sliding) along with this. By adopting an S-shape, the speed other than when the main shaft 225 is reversed is configured to be as constant as possible. In this way, the rotation of the handle is converted into the reciprocating motion of the main shaft 225.

  Conventionally, as can be seen from Patent Documents 1 and 2, spur gears are generally used for the first gear and the second gear, whereas helical gears are used in the present invention. The meshing between the helical gears increases the “meshing ratio” compared with the meshing between the spur gears, and the contact between the teeth averages and the rotation is stabilized. Accordingly, it is possible to transmit rotation with higher smoothness. Further, by adjusting the position in the axial diameter direction when the rotating shaft 211 is fixed, the meshing positions of the first gear 202 and the second gear 212, and the meshing positions of the idle gear 213 and the oscillating gear 221 are obtained. The optimal position without backlash can be maintained.

  Further, in the present invention, resin is used as the material of the first gear 211, the second gear 212, and the idle gear 213. Due to the flexibility of the resin, the impact at the time of contact between the teeth of the first and second gears and between the idle gear and the oscillating gear can be reduced, and the contact area of the teeth at the time of meshing can be increased. Thereby, it is possible to transmit rotation with higher smoothness. As the material of the resin, a hard material such as POM (polyacetal), PA (polyamide), PPS (polyphenylene sulfite), PEEK (polyether ether ketone) can be used. In this embodiment, the oscillating gear 221 is made of a metal such as a Zn alloy or Al, but the above-described resin may be used.

  In the above embodiment, the configuration in which the rotation of the handle is transmitted to the rotation of the oscillating gear 221 through the first gear 211, the second gear 212, and the idle gear 213 has been described. In particular, the configuration for transmitting to the oscillating gear is not limited to this, and other gear combinations are possible (for example, Patent Document 3). In that case, it is desirable that as many gear combinations as possible be a helical gear made of resin.
