Abstract

PROBLEM TO BE SOLVED: To provide a double bearing reel provided with a brake mechanism for making brake force act on free rotation in the fishing line delivery rotation of a spool and inhibiting the brake force from acting on the fishing line winding rotation of the spool rotated by the rotation of a handle. SOLUTION: A contact amount to a main shaft 4 is increased and decreased by compressing and restoring a coil spring A2 wound around a tapered surface formed at a spool shaft 4 in a contact state and resistance force is made to act on the spool shaft 4 and the brake force is imparted to the rotation of the spool 3 by the reduction of the winding diameter of the coil spring A2 accompanying the fishing line delivery rotation of the main shaft 4. Also, for the fishing line winding rotation of the main shaft 4, since the winding diameter of the coil spring A2 is widened, the resistance force does not act on the main shaft 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dual-bearing reel, and more particularly to a dual-bearing reel having a brake mechanism for applying a brake to free rotation of a spool.

[0002]

2. Description of the Related Art Conventionally, as a dual-bearing reel of this type, as shown in FIG. 3, for example, a brake adjusting knob 110 which is threaded axially reciprocally from the outside of a housing 100 and a distal end of a spool shaft 120 are fitted. There is a brake mechanism having a brake mechanism that tightens the brake adjustment knob 110 to press the brake adjustment knob 110 against the tip of the spool shaft 120 to apply pressure to apply a braking force to the rotation of the spool 130. ing. The above-mentioned brake mechanism prevents the backlash of the fishing line by giving a resistance to the rotation when the spool 130 is freely rotated to drop the device into the water, thereby suppressing the excessive rotation of the spool 130.

[0003]

However, in the above-described brake mechanism, the spool 130 is moved by the handle.
To rotate the spool line 1
Since the rotation of the handle 20 is performed, a braking force acts on the rotation of the handle for winding the fishing line. Therefore, the winding force of the steering wheel becomes heavy due to the braking force, and the braking force becomes a burden particularly when winding up a device dropped in a deep field or exchanging with a large fish. For this reason, the brake force is set to 0 after the mechanism is dropped, so that the brake mechanism is not actuated during winding, and the brake force is adjusted again when the mechanism is dropped again. That is, the above-mentioned dual-bearing reel has a problem that the braking force must be adjusted every time the device is dropped or wound up, so that it is very troublesome and the efficiency of fishing itself is significantly reduced. ing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional circumstances, and an object of the present invention is to apply a braking force to a free rotation in a fishing line payout rotation of a spool.
An object of the present invention is to provide a dual-bearing reel having a brake mechanism in which a braking force is not applied to a fishing line winding rotation of a spool rotated by rotation of a handle.

[0005]

A spool shaft supporting a spool is rotatably supported between the left and right housings, and the rotation of the spool is set to 0N, OFF of the clutch mechanism.
By switching, it is possible to switch between the drive rotation performed by the drive mechanism via the drag mechanism from the handle and the free rotation performed by separating the drive mechanism that transmits the rotation of the handle, and a brake is applied to the free rotation of the spool. In a dual-bearing reel having a brake mechanism to be actuated, the brake mechanism is wound around a tapered surface provided on a part of the outer peripheral surface of a spool shaft along the same taper around the tapered surface and in contact therewith. A coil spring, and a brake adjustment knob that is axially reciprocally penetrable from the outside of the housing so as to reciprocate in the axial direction, and that compresses and returns the coil spring in the axial direction of the tapered cylinder. The adjustment knob side has a large diameter, and the coil spring is connected to the brake adjustment knob and the spool And the starting end is fixed to the brake adjusting knob, and the winding direction of the coil spring is set in the direction in which the spool is pulled out from the larger diameter side to the smaller diameter side of the tapered surface. It is the same direction. (Claim 1)

The starting end of the above-mentioned coil spring is, for example, the left-hand side of the right-handed coil spring which is turned clockwise from left to right as the starting end. The coil spring has a characteristic that the winding diameter of the spring is reduced when the starting end side is fixed and the winding is twisted in the winding direction, and the winding diameter of the spring is increased when the coil spring is twisted in the opposite direction.

According to the present invention, the coil spring is in contact with the tapered surface of the spool shaft when the brake adjusting knob is set to the position where the braking force is maximized by the above-mentioned technical means. When the main shaft rotates in the fishing line payout direction, the diameter of the coil spring is reduced so as to wind around the tapered surface with the rotation. Therefore, a resistance force acts on the main shaft, and a load is applied to the rotational force of the main shaft, so that a braking force acts on the rotation of the spool. Since the winding diameter of the coil spring is increased with respect to the rotation of the main shaft for winding the fishing line, no resistance acts on the main shaft.

[0008] When the brake adjusting knob is moved in the direction of zero braking force, the coil spring is compressed along the axial direction of the tapered surface. At this time, the coil spring that has been in contact with the tapered surface is separated from the tapered surface by shifting from the corresponding tapered surface. Therefore, since the contact amount of the coil spring is reduced, the resistance to the main shaft does not act, and no load is applied to the rotation of the main shaft.
The braking force does not act on the rotation of the spool.

[0009] The coil spring is formed so that the urging force is gradually increased from the start end to the end. (Claim 2)

[0010] For example, the above-mentioned coil spring gradually reduces the diameter of the spring material at the start end side and gradually increases the diameter toward the end side, thereby gradually applying an urging force from the start end side to the end side. It is possible to strengthen.

[0011] According to the technical means of the second aspect,
The coil spring compresses and returns by adjusting the brake adjustment knob. However, since the urging force is gradually increased from the start end to the end, the coil spring compresses and returns for each turn of the coil spring. As a result, the resistance to the main shaft can be gradually changed, so that the range of adjustment of the braking force is widened.

Also, the brake force is adjusted from the maximum value to zero by tightening the brake adjustment knob into the housing. (Claim 3)

According to the third aspect of the present invention, since the brake force is reduced to zero by tightening the brake adjustment knob, the brake adjustment knob can be prevented from being detached due to excessive loosening of the brake adjustment knob.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a dual bearing reel according to the present invention will be described below with reference to the drawings. FIG. 1 shows a double bearing reel according to the present invention, in which a spool shaft 4 supporting a spool 3 between left and right housings 1 and 2.
Are rotatably supported, and the rotation of the spool 3 is performed by the drive mechanism 8 via the drag mechanism 7 from the handle 6 by switching the clutch mechanism 5 between 0N and OFF, and a drive mechanism for transmitting the rotation of the handle 6. 8 and can be switched to free rotation performed separately,
A brake mechanism A for applying a brake to the free rotation of the spool 3 is provided.

The spool shaft 4 includes left and right housings 1,
2 are supported by bearings 10 and 20 provided in the bearing 2. The spool shaft 4 includes a retaining portion 40 integrally formed on one outer periphery (the right side in the drawing) projecting into the left and right housings 1 and 2 and a pinion gear 91 described later fixed to the other outer periphery. By always contacting the bearings 10 and 20, sliding in the axial direction is prevented.

The spool 3 supported by the spool shaft 4 is mounted so as to rotate integrally with the spool shaft 4 and has both side plates 31 and 3 of the spool 3.
The outside of the housing 2 is in contact with the bearings 10 and 20, so that axial sliding between the left and right housings 1 and 2 is prevented.

A parallel fishing line winding mechanism 9 is provided between the left and right housings 1 and 2, and the above-described pinion gear 91 for driving the parallel winding mechanism 9 is fixed so as to rotate integrally with the spool shaft 4.

The brake mechanism A includes left and right housings 1, 2,
Are housed in the housing 1 (left side in the drawing) on the opposite side to the handle 6 side. The brake mechanism A has a tapered cylinder A1 fixed on the outer periphery of the spool shaft 4 in parallel with the pinion gear 91 fixed to the spool shaft 4, and a tapered cylinder A1 on the outer periphery of the tapered cylinder A1 along the taper of the same cylinder and in contact therewith. The wound coil spring A2 is axially reciprocally threaded through the housing 1 so as to be able to reciprocate in the axial direction from the outside, and the starting end side of the coil spring A2 is fixed to compress the coil spring A2 in the axial direction of the tapered cylinder A1. And a brake adjustment knob A3 for returning.

The tapered cylinder A1 has a large diameter on the brake adjustment knob A3 side and a small diameter on the pinion gear 91 side. The tapered cylinder A1 thus formed is
The fixing pin P is radially penetrated from the outer periphery thereof and is fixed to the spool shaft 4 so as not to rotate.

The coil spring A2 is disposed in a compressed state between the brake adjustment knob A3 and the pinion gear 91. The coil spring A2 has a starting end fixed to the brake adjusting knob A3, and the winding direction of the coil spring A2 is set to be the same as the fishing line payout direction of the spool 3 from the large diameter side to the small diameter side of the tapered cylinder A1. I have. The coil spring A2 is formed in a tapered shape in which the diameter of the spring material is the smallest at the start end and the largest at the end side.

The diameter of the brake adjustment knob A3 is slightly larger than the diameter of the spool shaft 4, the maximum diameter portion of the tapered cylinder A1, and the diameter of the tapered cylinder A1 with the coil spring A2 wound around the end facing the spool shaft 4. A three-step recess A31 is formed. In the state where the depth of the concave portion A31 in the brake adjustment knob A3 is most tightened, the depth is set so that the spool shaft 4 and the end portion of the tapered cylinder A1 do not come into contact with each other. The brake adjustment knob A3 thus formed is screwed to the housing 1 so as to cover the spool shaft 4 and the tapered cylinder A1. The brake adjusting knob A3 is screwed so as to adjust the braking force from the maximum value to zero by tightening the knob inside the housing 1. The starting end of the coil spring A2 is fixed to the bottom of the largest diameter recess in the three-step recess A31.

With the above configuration, when the brake adjusting knob A3 is rotated in a direction in which it is removed from the housing 1, the braking force is set to the maximum exertion position, and the coil spring A
2 comes into contact with the entire tapered surface of the tapered cylinder. When the main shaft 4 rotates in the fishing line payout direction in the above state, the diameter of the coil spring A2 is reduced so as to wind around the tapered surface with the rotation. Therefore, the resistance force of the coil spring A2 acts on the main shaft 4, and a load is applied to the rotational force of the main shaft 4, so that a braking force acts on the rotation of the spool 3.
Further, since the winding diameter of the coil spring A2 is increased with respect to the rotation of the main shaft 4 for winding the fishing line, no resistance force acts on the main shaft 4. Therefore, the fishing line can be wound without receiving the load of the brake.

When the brake adjustment knob A3 is rotated in the tightening direction, the brake adjustment knob A3 moves in the direction of zero braking force, and the coil spring A2 is compressed along the axial direction of the tapered cylinder A1. At this time, the coil spring A2 that has been in contact with the tapered surface is separated from the tapered surface by being displaced. Accordingly, since the contact amount of the coil spring A2 is reduced, the resistance to the main shaft 4 does not act, the load is not applied to the rotational force of the main shaft 4, and the brake force does not act to the rotation of the spool 3.

The coil spring A2 is formed such that the diameter at the start end of the spring material is the thinnest and the diameter is gradually increased toward the end, and from the start end toward the end. Since the biasing force is gradually increased, the coil spring A2 is adjusted by adjusting the brake adjustment knob A3.
Compression and return for each turn. Therefore, the resistance to the main shaft 4 can be gradually changed, and the range of adjustment of the braking force is widened.

Further, since the brake adjustment knob A3 is tightened inside the housing 1 to adjust the brake force from the maximum value to zero, the falling off of the brake adjustment knob A3 due to excessive loosening of the knob is prevented. Loss can be prevented.
