Japanese Patent Application Laid-Open No. 9-84500

In the spinning reel as described above, when a high load acts during the winding operation of the handle during actual fishing, a force that pry the lid body acts through the handle shaft and the bearing that rotatably supports the handle shaft. .. Since the lid body closes the opening of the body and is fixed by a plurality of screw members, a force that twists the lid body acts on the body, or a thrust force that acts on the meshing portion acts on the body. On the other hand, a slight force (lifting phenomenon) is generated in the direction in which the lids are separated from each other. Then, due to the influence of this floating phenomenon, wear of the meshing portion of the pinion gear and the drive gear and its bearing may be promoted, and the meshing accuracy may not be stably maintained and the rotational performance may be deteriorated. .. This tendency becomes remarkable especially when the lid is made of a synthetic resin material.

The present invention has been made by paying attention to the above-mentioned problems, and by suppressing the deformation of the lid that closes the opening of the body during a high-load winding operation with a simple configuration, the winding drive mechanism. It is an object of the present invention to provide a spinning reel for fishing, which maintains the rotational performance of the fishing reel and prevents the durability of each part from being lowered.

In order to achieve the above object, the spinning reel for fishing according to the present invention includes a reel body including a body for accommodating a take-up drive mechanism, a lid for closing an opening of the body, and the reel. A rotor that is rotatably provided on the main body and is rotationally driven by the rotation operation of a handle shaft provided on the reel main body, a spool that is rotatably supported by the reel main body and around which fishing thread is wound, and the rotor. It has a reverse rotation prevention device that prevents reverse rotation at the time of winding the fishing reel and is operated by the rotation operation of the switching operation unit, and deforms the lid body in a state where the opening of the body is closed. It is characterized in that it is regulated by the shaft portion of the switching operation portion of the reverse rotation prevention device.

In the fishing spinning reel having the above configuration, a switching operation unit that operates the reverse rotation prevention device is provided on the lid portion that closes the body, and a shaft portion that supports the switching operation unit to operate is used. , The force acting on the lid (the force that tries to separate the lid from the body) is suppressed. Therefore, without using a special structure for preventing the deformation of the lid, it is possible to effectively prevent the deformation of the lid with a simple configuration only by using the switching operation unit of the reverse rotation prevention device. It is possible to prevent the rotation performance of the take-up drive mechanism from deteriorating and the durability of each part from deteriorating.

In the above configuration, the switching operation unit may be held by the lid body by the shaft portion so as to rotate during actual operation, and may be in a lever form or a dial form, and is appropriately deformed. It is possible to do. Further, it is preferable that the ON state / OFF state is switched and held at each position.

According to the present invention, during a high-load winding operation, deformation of the lid that closes the opening of the body can be suppressed with a simple configuration, the rotational performance of the winding drive mechanism is maintained, and the durability of each part is maintained. A spinning reel for fishing that prevents deterioration of sex can be obtained.

The cross-sectional view of the main part which shows the structure of the reverse rotation prevention device and the switching operation part. FIG. 3 is a cross-sectional view taken along the line CC of FIG.

Hereinafter, an embodiment of a spinning reel for fishing according to the present invention will be specifically described with reference to FIGS. 1 to 7.

The reel body 1A of the fishing spinning reel (hereinafter referred to as a reel) 1 according to the present embodiment is integrally formed with a reel leg 2 having a rod mounting portion 2A formed at a tip mounted on a fishing rod. A rotor 3 rotatably supported and a spool 5 rotatably supported in synchronization with the rotational movement of the rotor 3 are arranged in front of the rotor 3.

The reel body 1A includes a body 1B that houses a take-up drive mechanism 50 described later, and a thin plate-shaped lid 1D that closes an opening 1C of the body 1B. Further, the rotor 3 includes a pair of arm portions 3a that rotate around the spool 5, and a bale support member 3c to which a base end portion of the bale 3b is attached is attached to each front end portion of each arm portion 3a. It is rotatably supported between the fishing thread winding position and the fishing thread discharging position. In this case, one base end portion of the bale 3b is attached to a fishing thread guide portion (line roller) 3d integrally provided on the bale support member 3c.

The rotor 3 of the present embodiment is arranged so that the rear end side of the rotor 3 overlaps the cylindrical accommodating portion 1E on the front end side of the reel body 1A in the axial direction, and the rear end surface (bottom surface) 3A is the reel body 1A (cylinder). It is rotationally driven in a state where a certain gap is formed in the radial direction with the outer surface of the accommodating portion 1E).

As shown in FIG. 7, a handle shaft 7 is rotatably supported in the reel body 1A via a pair of bearings 7a and 7b, and a handle 7c is attached to a protruding end portion thereof. The handle shaft 7 is supported so as to project from both sides of the reel body 1A, and as is known, the handle 7c is mounted on either one (right-handed winding / left-handed winding), and the side on which the handle is not mounted. A cap 7d is attached to the handle shaft of the above. In FIG. 1, the rotor 3 and the handle 7c described above are omitted.

A take-up drive mechanism 50 is engaged with the handle shaft 7, and the take-up drive mechanism 50 meshes with a drive gear 8 rotatably mounted on the handle shaft 7 and the drive gear 8. A pinion 10 is provided as a rotation drive shaft (drive unit) having a pinion tooth portion 10a and having a cavity portion extending in a direction orthogonal to the handle shaft 7 and extending in the axial direction inside.

The pinion 10 can be rotated in the reel body 1A by a pair of bearings 12a and 12b in which the front side and the rear side of the pinion tooth portion 10a are fitted and supported by the support portion of the reel body 1A (body 1B), respectively. It is supported. Further, the pinion 10 extends toward the spool 5, and a rotor 3 is integrally rotatably attached to the tip of the pinion 10 via a rotor nut.

A one-way clutch 21 constituting the reverse rotation prevention device 20 is mounted on the pinion 10 on the front side of the bearing 12a arranged on the front side of the pinion tooth portion 10a, and a switching operation provided outside the reel body 1A. By rotating the portion 30, the reverse rotation of the handle (rotor 3) in the fishing thread feeding direction is prevented.
That is, the rotor 3 can be switched between the reverse rotation prevention state (ON state of the reverse rotation prevention device) and the reverse rotation possible state (OFF state of the reverse rotation prevention device) by rotating the switching operation unit 30. ing.

A spool shaft 15 extending in a direction orthogonal to the handle shaft 7 and having a spool 5 mounted on the tip side thereof is inserted into the hollow portion formed inside the pinion 10 so as to be movable in the axial direction. The spool shaft 15 is reciprocated back and forth by a spool reciprocating device 40 driven via a gear train connected to a pinion 10.

The spool reciprocating device 40 is rotatably supported in the reel body so as to be parallel to the spool shaft 15, and engages with the spiral groove 41a having a spiral groove 41a formed on the outer peripheral surface thereof. A guide that holds the engaging pin 43a to be engaged and guides the slider 44 fixed to the rear end of the spool shaft 15 via a screw 43 and the slider 44 so as to slide in the front-rear direction. It is provided with a shaft 45 (in FIG. 7, the position of the slider 44 is shown as being moved forward to the position of the cross-sectional line CC in FIG. 3). Further, as shown in FIG. 4, the spool reciprocating device 40 includes a power transmission gear (gear train) 47 that meshes with the tooth portion 10a of the pinion 10 that is rotationally driven by the drive gear 8. The power transmission gear 47 of the present embodiment is configured as a two-stage gear, and includes a large-diameter gear 47a that meshes with the tooth portion 10a of the pinion and a small-diameter gear 47b attached to the large-diameter gear. When the small-diameter gear 47b meshes with the input gear 41b fixed to the end of the screw shaft 41, the rotational drive of the handle shaft 7 is decelerated and transmitted to the screw shaft 41.

According to the above configuration, when the handle 7c is wound up, the rotor 3 is rotationally driven via the drive gear 8 and the pinion 10 constituting the take-up drive mechanism 50, and the drive gear 8, the pinion 10, and the power transmission gear ( The screw shaft 41 is decelerated and rotationally driven via the two-stage gear) 47 and the input gear 41b, and the spool shaft 15 (spool 5) fixed to the slider 44 is reciprocated in the front-rear direction. Therefore, the fishing thread is evenly wound around the spool 5 via the fishing thread guide portion 3d of the rotor 3 that is rotationally driven.

The take-up drive mechanism 50 and the spool reciprocating device 40 described above are housed in the body 1B constituting the reel body 1A, and in that state, the lid 1D is covered so as to close the opening 1C of the body 1B, and a plurality of reel bodies 1A are covered. The lid body 1D is fixed to the body 1B by screwing the screw 1f. When a high load acts on the lid 1D during the winding operation of the handle 7c during actual fishing, the lid 1D is twisted via the handle shaft 7 and bearings 7a and 7b that rotatably support the handle shaft 7. Force acts. That is, the lid 1D attached to the body is attempted to be separated from the body 1B by a twisting force or a thrust force acting on the meshing portion between the gears. A force (a force that tries to deform the lid, which is a floating phenomenon of the lid) acts. Then, due to the influence of this floating phenomenon, wear of the meshing portion of the pinion gear and the drive gear, the bearings 12a, 12b, etc. is promoted, and the meshing accuracy cannot be stably maintained, and the rotational performance may be deteriorated. There is sex.
Such a phenomenon is effectively prevented by the arrangement mode of the switching operation unit 30 of the reverse rotation prevention device 20 described in detail below, particularly by the shaft portion 31 that rotatably supports the switching operation unit 30. ing.

Hereinafter, the configuration of the reverse rotation prevention device 20 (one-way clutch 21) and the switching operation unit 30 for operating the device will be described.
As shown in FIG. 3, the one-way clutch 21 has an inner ring 22 that is anti-rotated to the pinion 10 and a cage 23 that holds a plurality of rolling members 26 on the outside of the inner ring 22 in the circumferential direction. And an outer ring 25 arranged on the outside of the cage 23. As is known, on the inner peripheral surface of the outer ring 25, a free rotation region in which a plurality of rolling members 26 held by the cage 23 can freely rotate and a wedge region in which the rotation of the plurality of rolling members 26 is prevented are provided. Is formed, and each rolling member 26 is urged to the wedge region by a spring member (not shown) provided on the cage 23.

In the one-way clutch 21 having such a configuration, when the inner ring 22 rotates in the forward direction (the rotor 3 rotates in the fishing thread winding direction) together with the pinion 10, the rolling member 26 held by the cage 23 enters the free rotation region of the outer ring 25. Positioned so that the rotational force of the inner ring 22 is not transmitted to the outer ring 25 (not blocked by the outer ring 25) and therefore the rotor 3 rotates with the pinion 10 without hindrance. On the other hand, when the inner ring 22 tries to rotate in the reverse direction (the rotor 3 rotates in the fishing thread feeding direction) together with the pinion 10, the rolling member 26 held by the cage 23 is located in the wedge region of the outer ring 25 by the spring member. , The rotational force of the inner ring 22 is transmitted to the outer ring 25, which serves as a stopper to prevent the reverse rotation of the pinion 10 and the rotor 3 (one-way clutch reverse rotation prevention state; ON state).

The one-way clutch 21 constituting the reverse rotation prevention device can be switched from the reverse rotation prevention state to the reverse rotation possible state (OFF state) by the rotation operation of the switching operation unit 30. Specifically, the switching operation unit 30 has a shaft portion 31 extending substantially parallel to the spool shaft 15 in the reel body 1A, and the tip protrusion 31a of the shaft portion 31 is in the radial direction of the cage 23. It is engaged and connected to the engaging hole 23b of the extending extension portion 23a (see FIGS. 5 and 6). Further, the base end portion of the shaft portion 31 is fixed to the switching operation portion 30 by a screw 33, and by rotating the switching operation portion 30, the cage 23 is rotated in the circumferential direction via the shaft portion 31. It is possible to make it. In this case, a distribution spring 36 is attached to the shaft portion 31 from the reel body 1A so as to distribute and hold the rotation position of the cage 23 at two locations (ON state and OFF state). Has been done.

That is, when the switching operation unit 30 is rotated and the cage 23 is distributed and held so that the rotation position of the cage 23 is in the ON state (position in FIG. 4P1), the rolling member 26 has the inner ring 22 as described above. It is maintained in a state where it allows forward rotation of the (pinion) and prevents reverse rotation. Further, when the switching operation unit 30 is rotated and the cage 23 is distributed and held so that the rotation position of the cage 23 is in the OFF state (position of P2 in FIG. 4), the rolling member 26 has an urging force of the spring member. It is forcibly located in the free rotation region of the outer ring 25 against the above, and is held in a state of allowing forward rotation and reverse rotation of the inner ring 22 (pinion). By rotating the switching operation unit 30 in this way, the position where the forward rotation of the rotor 3 is allowed and the reverse rotation is prevented and the position where the forward / reverse rotation of the rotor 3 is allowed are selectively selected. Switching operation is possible.

The switching operation unit 30 of the present embodiment is configured in a lever form, and is in a region within the contour of the side surface of the reel body 1A (lid body 1D) and on the side opposite to the rod mounting portion 2 with respect to the handle shaft 7. It is rotatably arranged in. Here, the contour of the side surface of the reel body 1A means an edge that defines the outer shape of the reel body 1A (lid body 1D) as shown by the dotted line E in FIGS. 2 and 3, and is the present embodiment. The switching operation unit 30 is arranged in the region of the edge E and is arranged so as not to protrude (expose) from the region.

Since the switching operation unit that operates the reverse rotation prevention device in the conventional spinning reel for fishing is arranged so as to protrude from the contour of the main body 1A (lid body 1D) (protrude to the outside), the fishing thread is entangled during actual fishing. It was easy to move to a fishing spot or during transportation, and there was a possibility that other objects would come into contact with each other and cause damage. However, as in this embodiment, the reel body 1A (lid body 1D) is arranged within the contour of the handle. By rotatably arranging the shaft 7 in the region opposite to the rod mounting portion 2, the rod does not protrude to the outside, and it is possible to effectively prevent thread entanglement and breakage.

Then, as shown in FIG. 6, the lid body 1D attached to the body 1B is in a state in which the lifting is restricted by the shaft portion 31 of the switching operation unit 30 described above. In this case, the regulation of the lid body 1D means that the lid body 1D is regulated with respect to the body 1B due to the force acting on the lid body 1D, the thrust force acting on the meshing portion between the gears, and the like. Even if a force (force to deform the lid) acts to separate the lid in the direction of arrow D1 (FIG. 5), the lift is suppressed (pressed) by the shaft portion 31 of the switching operation unit 30. ) Means that. That is, a support portion of the switching operation portion 30 is formed on the lid body 1D, and the shaft portion 31 of the switching member 30 is engaged with this portion to regulate the lifting of the lid body 1D.

In the present embodiment, a flange 1Da that serves as a support portion of the shaft portion 31 is formed on the front side of the lid body 1D, and a through hole 1Db is formed in the flange 1Da, and when the lid body 1D is attached, the through hole 1Db is formed. By inserting the shaft portion 31 of the switching operation portion 30, the lifting of the lid body 1D in the direction of the arrow D1 is restricted. Therefore, the lid 1D is not deformed to be twisted, the durability is improved without wearing the meshing portion of the pinion gear and the drive gear, the bearings 12a, 12b, etc., and the meshing accuracy is stably maintained. It becomes possible to do.

Moreover, when arranging the switching operation unit 30 of the reverse rotation prevention device usually provided as a spinning reel at a position where the fishing thread is not caught, the shaft portion 31 of the switching operation unit 30 which exerts the action effect that the fishing thread is not caught is used. Since the deformation of the lid is regulated, the number of parts for suppressing the deformation of the lid is not increased, the configuration is simplified, and the cost is not increased.

The shaft portion 31 of the switching operation portion 30 described above is formed on the lid 1D with a support portion for the switching operation portion (for example, a flange as in the present embodiment, or a concave portion or a lid formed on the lid). If the configuration is such that the lifting of the lid 1D can be regulated by forming a projecting piece, etc. to be formed) and engaging (penetrating, fitting, partially contacting, etc.) the shaft portion 31 with the support portion, switching is performed. The configuration of the support portion for holding the operation portion 30, the arrangement mode of the shaft portion 31, and the specific regulation method are not limited.

Further, in the present embodiment, the switching operation unit 30 is arranged in a region on the front side (preferably, on the front side and the lower side of the handle shaft as in the present embodiment) with respect to the axis of the handle shaft 7. Therefore, regulation can be performed near parts such as bearings of the take-up drive mechanism 50, which affects when the lid is subjected to a twisting force, and more effectively prevents wear of the parts and makes the meshing part. It can be maintained with high accuracy. Further, by arranging at such a position, the length of the shaft portion 31 connected to the cage 23 of the one-way clutch can be shortened, which improves the strength at the connecting portion and operates. Not only can it be stabilized, but it can also be made lighter.

Further, since the switching operation unit 30 is located near the rotor side, another object such as a finger may accidentally touch the switching operation unit 30 due to the radial bulge of the rotor 3 during actual fishing or handling. It is possible to prevent the reverse rotation prevention device from malfunctioning. In particular, in the present embodiment, at least a part of the switching operation unit 30 is arranged so as to be located on the spool side of the rear end surface 3A of the rotor 3, so that a part of the switching operation unit 30 is formed by the rotor 3. It will be in a covered state, making it difficult for other objects to come into contact with it, and it will be possible to reliably prevent damage and malfunction.

In the present embodiment, the switching operation unit 30 to be rotated is in the form of a lever, and the base end side thereof is supported by the screw 33 with respect to the side surface of 1A of the reel body (the lid body 1D that closes the reel body). Since it is configured to be undulating as shown in FIG. 4, it is compared with a configuration in which the rod mounting portion is rotationally arranged in the width direction on the rear side of the rod mounting portion as in the configuration disclosed in Patent Document 1. Therefore, it is possible to immediately grasp the state of the one-way clutch. In this case, since it is rare to switch the reverse rotation prevention device to the OFF state (reversible state) during actual fishing, etc., the reel body 1A (lid body 1D) is held lying down along the side surface. It is preferable that the reversed state P1 is set to the reverse rotation prevention state (ON state), and in the reverse rotation possible state (OFF state), the reel body 1A (lid body 1D) is switched and held in a standing state P2 from the side surface.

Further, a recess 1d is formed on the surface of the side surface (lid body 1D) of the reel body 1A so that when the switching operation unit 30 falls down, the switching operation unit does not protrude from the surface as much as possible (switching operation unit). 30 and the surface of the lid 1D are substantially flush with each other). According to such a configuration, thread entanglement can be prevented more effectively, and other objects can be reliably prevented from being caught.

Further, in the configuration in which the switching operation unit 30 is undulated as described above, it is preferable to switch and hold the switching operation unit 30 in the laid-down ON state so as to create a space between the switching operation unit 30 and the lid body 1D. For example, in the present embodiment, the convex portion 1e is formed in the concave portion 1d, and when the switching operation portion 30 falls down, it abuts on the convex portion 1e to regulate the rotation position, and the convex portion is regulated. Space S is created by.

According to such a configuration, when the switching operation unit 30 is rotated from the ON state to the OFF state, the space S makes it easier to catch a finger, and the operability can be improved. As a method for forming such a space S, in addition to the above, the diameter of the tip side of the switching operation unit 30 may be reduced, or the taper 30c may be formed on the tip side.

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 variously modified. In the above-described embodiment, the switching operation unit 30 to be rotated is in the form of a lever, but it may be a dial type that can be rotated by pressing with a finger, or a part of the dial can be picked up with a finger. It can be appropriately deformed, such as having a structure having protrusions. Further, the arrangement position of the switching operation unit 30 can be appropriately deformed, and if the shaft portion 31 of the switching operation unit 30 regulates the lifting of the lid body 1D, the configuration thereof is appropriately deformed. It is possible to do. Further, the present invention is characterized in that the lift of the lid is regulated by using the shaft portion of the switching operation unit 30 that operates the reverse rotation prevention device, and other configurations are the same as those of the embodiment shown in the figure. It is not limited to the configuration.
