DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel.

[0002]

2. Description of the Related Art A spinning reel winds a fishing line on a spool while moving the spool back and forth with the rotation of a handle by an oscillating mechanism having a slider fixed to the rear end of a spool shaft having a spool attached to the front end. Is what you take. When winding the fishing line with this handle rotation,
The play in the rotation direction of the spool around the spool shaft occurs, which causes abnormal noise during rotation of the handle, and hinders the smooth stabilization of the fishing line winding operation. Further, a spinning reel having a thread drop prevention mechanism provided between a spool and a rotor is known. However, interference with the thread drop prevention mechanism further worsens the above-mentioned abnormal rotation state, and also has a function of the thread drop prevention mechanism. It also causes a decline.

[0003] The spool is frictionally fixedly connected to the spool shaft, and since the slider is fixed to the spool shaft, the sliding gap of the slider causes play. Japanese Patent Publication No. Sho 61-6766 discloses an apparatus in which the lower end of a slider is slidably fitted to a guide rail formed on a reel frame to prevent backlash. Further, a slider is fitted to a guide rod member attached to the reel frame so as to be movable back and forth.
No. 66 is disclosed.

[0004]

However, from the viewpoint of the machining accuracy and the assembly accuracy of the parts, it is necessary to loosely fit the rail portion and the play regulating portion of the guide rod member in order to smoothly operate the slider back and forth. Therefore, it is inevitable that the slider will play around the spool shaft.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a spinning reel with reduced play around a spool shaft of a slider. It is another object of the present invention to provide a spinning reel which does not hinder the weight reduction of the reel, performs a stable back and forth operation, and reduces the play around the spool shaft of the slider.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention provides a slider attached to a rear portion of a spool shaft having a spool attached to a tip portion, and a handle is rotated by an oscillating mechanism having the slider. Provided is a spinning reel that converts the movement into a back-and-forth movement and moves the spool back and forth, wherein the slider is biased and supported by a resilient member so as to be able to move back and forth with respect to a reel frame or an oscillating gear. .

Further, the present invention provides a spinning reel in which the elastic member is erected in the front-rear direction of the reel frame so as to bias and support the slider against a guide member for guiding the slider in the front-rear direction. Further, the present invention provides a spinning reel in which the elastic member is a leaf spring fixed to a slider, and an end of the leaf spring is pressed against an inner wall of the reel frame.

[0008]

The slider can be constantly pressed by the elastic force if the slider is urged and supported by a reel frame or an oscillating gear when the slider has an oscillating gear. Can be reduced.

The guide member, which is integrally fixed to the reel frame in the narrow direction in the front-rear direction, is considered to be a reel frame in a broad sense. Furthermore, unlike the reel frame in a narrow sense, the guide member is a small part and can be formed of metal or the like with a very small increase in weight, and the strength can be improved and the friction when the slider moves back and forth can be reduced. Operation becomes possible. When the leaf spring is fixed to the slider as an elastic member, the slider moves back and forth together with the slider, so that compared with the case where an elastic member such as a leaf spring is fixed along the inner wall of the reel frame, the longitudinal movement stroke of the spool is reduced. Small leaf springs can be used regardless of the length, and play can be reduced while reducing weight. Also, unlike a coil spring or the like, stable sliding is possible by pressing a plate surface (including a thin linear surface) against the reel frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a side view of a partially broken spinning reel according to the present invention, FIG. 2 is an enlarged view of a main part thereof, and FIG. 3 is a cross-sectional view taken along line CC of FIG. The spool 12 is frictionally coupled to a leading end of the spool shaft 10, and a slider 18 is fixed to a rear end of the spool shaft 10 by a screw member 28. Further, a pinion gear 17 connected to the rotor 14 is fitted over the intermediate portion of the spool shaft 10 with a gap, and a drive gear 16 is rotated by rotating a handle, and the pinion gear 17 is connected to the drive gear. The rotor 14 is rotated because it meshes with the rotor 16.

A cam shaft 20, which is arranged in parallel with the spool shaft 10 and rotates in conjunction with the drive gear 16, is supported by a reel frame 22.
A is formed. The slider 18 has an engaging portion 18A.
And is engaged with the cam groove 20A of the cam shaft. Accordingly, the spool shaft 10 linearly moves back and forth with the slider 18 with the rotation of the handle. This mechanism is called an oscillating mechanism.

Accordingly, the spool 12 connected to the spool shaft 10 moves back and forth in synchronization with the rotation of the rotor 14, so that the fishing line is evenly wound around the spool. As described above, the slider 18 essentially moves only linearly, but there is some play in the rotation direction about the spool shaft 10.
In order to prevent this backlash, a leaf spring 24 is fixed to the slider 18 by a holding plate 25.
And pressed against the inner surface of the reel frame 22 as shown in FIG.

Accordingly, the slider 18 is urged about the spool shaft 10 in the direction of the arrow in FIG.
8S is pressed against the inner surface 22S of the reel frame by a predetermined force. Therefore, the slider 18 is brought into contact with the inner surface of the reel frame 22 by the urging force of the leaf spring 24, so that play can be prevented according to the urging force of the leaf spring 24. Since the slider 18 slides back and forth on the inner surface of the reel frame 22 together with the leaf spring 24, the sliding stability must be ensured.

The leaf spring 24 as an elastic member can be stably slid because it is in contact with the reel frame 22 by the end plate surface. Further, since the leaf spring moves together with the slider 18, the width thereof may have a predetermined width from the viewpoint of strength regardless of the sliding stroke. Therefore, the leaf spring hardly increases the weight of the reel. Further, the slider 18
Inner surface 22S of the reel frame 22 with which the end surface 18S contacts
It is preferable to attach a material having a smooth surface and abrasion resistance, such as ceramics and metal, for smooth and stable operation.

FIG. 4 shows a modification of the above embodiment, in which a slider 18 ′ is fitted over a guide member 29 erected over the front and rear of the reel frame, and is urged by a leaf spring 24. The slider 18 'is pressed against the guide member 29, and is slid in this state. Therefore, the slider 18 'can be prevented from rattling around the spool shaft 10. The guide member 29
If formed from a metal, it can be formed in a small diameter without lowering the strength, and the sliding friction on the surface is reduced. Therefore, stable operation can be achieved, and weight increase is small. Leaf spring 24
The protrusion 24A is provided so that the operation of sliding on the inner surface of the reel frame 22 is facilitated. Also in this case, it is preferable to attach a plate member having a wear-resistant and smooth surface such as ceramics or metal to the inner surface of the reel frame 22.

FIG. 5 shows another modification, in which the camshaft 20 is surrounded by a half cylindrical member 32, which is fixed to the reel frame 22. The slider 18 fitted over the cylindrical member 32 as a part of the reel frame 22 is pressed by the urging force of the leaf spring 24 to prevent backlash. The convex portion 22A extending in front and rear of the reel frame 22 with which the leaf spring 24 is in contact is for facilitating relative front-rear operation between the leaf spring 24 and the reel frame 22. Similarly, it is preferable to attach ceramics or metal.

FIG. 6 shows still another modification, in which a leaf spring 2 is provided.
The slider 18 is supported from both sides by pressing the respective ends 24A 'and 24B' of the 4 'against the inner surface of the reel frame 22, so that play of the slider 18 around the spool shaft 10 can be prevented. .

FIG. 7 shows another modification, in which the leaf spring 24 "is configured so that its end presses the step surface 22A 'of the reel frame 22 by elasticity, so that the play of the slider 18 is reduced. To prevent.

Next, FIG. 8 shows an embodiment of the present invention in the case of having an oscillating mechanism of another form. The oscillating pinion 30 that rotates together with the drive gear 16 rotates the oscillating gear 32, and has an engaging projection 32A at an eccentric position of the oscillating gear 32, and engages with the engaging projection 32A. A slider 26 having an elongated hole 26H is fixed to an end of the spool shaft 10 by a screw member 28. Therefore, when the handle is rotated, the oscillating gear 32 is rotated, and the engagement convex portion 32 is rotated.
The slider 26 moves back and forth by the engaging action between A and the elongated hole 26H.

Referring also to FIG. 9 along the line II of FIG. 8, a leaf spring 24 is fixed to the slider 26 by the screw member 28, and an end 24A of the leaf spring is fixed to the reel frame. 22 is pressed against the step 22A ', whereby the slider 26 is prevented from rattling in the direction of rotation with the spool shaft 10.

FIG. 10 shows a modification, in which the slider 26 is the same as that shown in FIG.
In the case where it is attempted to rotate in the counterclockwise direction at 0, the backlash in this direction can also be prevented by the projection 24B 'at the other end of the leaf spring 24', and the backlash between the end 24A 'and the step 22A' is prevented. In addition, the operation of the slider 26 is stabilized.

FIG. 11 shows another modification, in which a leaf spring 24 "is fixed to the inner surface of a cover 23 as a part of the reel frame, and the slider 26 is pressed against the step 22A 'of the reel frame 22. Thus, the slider 26 can prevent the backlash from rotating around the spool shaft 10. By attaching the leaf spring 24 "to the reel frame in this manner,
In the reel assembling operation, the assembling operation of the slider 26 becomes considerably easier.

FIG. 12 shows another modification. A coil spring 25 as an elastic member is embedded in the reel frame 22 on which the oscillating gear 32 is rotatably mounted. The coil spring 25 pushes up a plane of the oscillating gear 32 via a plate member 34. And is in contact with the slider 26. Oscillating gear 32
Is rotated, contacting the ends of the coil springs 25 directly increases friction, so that the plate member 34 is made of a smooth and highly wear-resistant plate member such as a ceramic plate or a metal plate. Is preferably formed.

FIG. 13 is a side view taken along line M of FIG. 1. As shown in FIG. 13 and FIG. 1, the rotor 14 is provided with support arms 44 on both sides.
The bail support member 42 to which the “0” is attached is attached. When the bail 40 is inverted to the fishing line release position, the link 48 is lowered in FIG. 13 and connected to the lower end of the link 48, and the kick lever 46, which is annular in a side view, rotates about the support shaft 48 as a pivot. In 1, the tip of the L-shaped kick lever 46 is positioned to be engageable with the cam surface 50S of the cam 50 formed at the front of the reel frame 22.

In this state, if the handle is rotated to wind the fishing line, the kick lever 46 engages with the cam surface 50S of the cam portion 50 with the rotation of the rotor 14, and
The bail 40 is rotated about the pivot 8 to push up the link 48 to return the bail 40 together with the bail support member 42. As described above, the bail reversing mechanism is built in the support arm 44, and the kick lever 46 is rotated around the support shaft 48, so that the reversion return force can be reduced, and a smooth reversal operation can be performed. 44 can be made compact, the rear corner 44S can be formed smoothly, and the entanglement of the fishing line at this position can be prevented.

[0026]

As is apparent from the above description, according to the present invention, if the slider is biased and supported against the reel frame or the oscillating gear when the slider is provided by the elastic member. The slider can always be pressed by the elastic force, and the play can be reduced. Accordingly, abnormal noise at the time of operating the steering wheel can be prevented.
