Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drag braking device for a fishing reel using an elastic body as a braking member.

Conventionally, in order to apply drag braking force to the rotation of the spool of a fishing reel, for example, friction washers were placed alternately between a braking plate that rotates with the spool and a braking plate that is integral with the spool shaft in the recess on the front surface of the spool of a spinning reel. This was done by pressing the drag brake adjustment knob screwed onto the spool shaft.

Therefore, since a plurality of brake plates of two types and a plurality of 7-reaction washers are required, the number of parts increases and assembly and disassembly are troublesome. In addition, since a plurality of metal braking plates are used, there is a drawback that the brakes are heavy.

Further, it is troublesome to process the long grooves for preventing rotation between the spool and the brake plate, and when the spool is made of synthetic resin, a reinforcing member is required to engage the long grooves and the brake plate.

SUMMARY OF THE INVENTION In view of the above drawbacks, an object of the present invention is to propose a drag braking device for a fishing reel that is simple in structure, easy to assemble and disassemble, is lightweight, and provides a strong drag braking force.

Hereinafter, the present invention will be explained with reference to the illustrated embodiments.The first embodiment of the drag braking device stirrup will be described in the case where the spool concave portion of the spinning reel is a cylinder of a bottomed cylindrical member.
A gear 2 having a boss portion is fixed to the spool shaft 1, and a through hole 3a on one side of the reel 3 is provided on the outer periphery of the boss portion 2a. are rotatably fitted.

A recessed cylinder 3b is formed in the spool 3 to constitute a bottomed cylindrical member of the reel, and an elastic body 4 and a plate-shaped pressing member 5 are fitted into the cylinder 3b, and the shaft 1 inside the cylinder 3b The elastic body 4 and the pressing member 5 are fitted so as to be non-rotatable in the outer circumferential direction and movable in the axial direction.

A drag brake adjustment knob 6 is screwed onto the front end of the shaft 1, and when the knob 6 presses the pressing member 5, the elastic body 4 is compressed. Friction f occurs between the end face of the elastic body 4 and the end face 2b of the boss portion.
It is configured to operate with lllJ power.

The elastic body 4 is made of urethane resin, rubber, or the like, and is integrally fixed non-rotatably in the outer circumferential direction of the shaft by a protrusion 5a formed on the end face of the pressing member 5.

The elastic body and the pressing member may be fixed by sintering.

When the first embodiment is configured as described above and the fishing line wound around the spool 3 is paid out by the pull of the catch, the spool 3
is supported and rotated by the fit between the outer periphery of the boss portion 2a and the through hole 3a, and drag braking is applied to the reverse rotation of the spool due to the frictional braking force between the outer circumferential surface of the elastic body 4 and the cylindrical wall of the cylinder 3b. It will be done.

FIG. 2 shows a second embodiment of the drag braking device, in which the cylindrical portion protruding from the rear of the reel body 7 is a bottomed cylindrical member, and the bottomed cylindrical member 7a has a concave tube 7b. The elastic body 4, the plate-shaped pressing member 8, and the auxiliary plate 9 are fitted together, and the drag brake adjustment knob 10 provided on the outer periphery of the bottomed cylindrical member 7a is used to adjust the spring 11.
The elastic body 4 is configured to be pressed via the pressing member 8.

A through hole is bored in the bottom surface of the bottomed cylinder 7b, and a hollow shaft 12 is protruded from inside the reel body into the cylinder.
The elastic body 4 and the auxiliary plate 9 are fitted so as to be non-rotatable in the outer circumferential direction of the elastic body 2 and movable in the axial direction. A spool shaft 13 is fitted into the central hole of the hollow shaft 12 so as to be movable in the axial direction, and a spool (not shown) is fixed to the tip of the spool shaft 13.

A protrusion 9a is formed on the end surface of the auxiliary plate 9, and the elastic body 4
are fixed together. Both may be sintered and fixed as described above.

Further, the auxiliary plate may be fitted into the cylinder 7b so as to be attached to the plate-shaped pressing member 8.

It is preferable that the pressing member 8 is provided with a protrusion 8a on its outer periphery and is fitted into a long groove 7C formed in the cylinder 7b to prevent rotation while being movable in the axial direction.

When the second embodiment is configured as described above and the spool shaft 13 is rotated by the spool (not shown), the elastic body 4 and the auxiliary plate 9 are rotated, and the outer peripheral surface of the elastic body 4 and the cylinder wall of the cylinder 7b are rotated. A friction braking force acts between the circumferential surface and between the end surface of the elastic body 4 and the pressing member 8, and drag braking is applied to the reverse rotation of the spool.

FIG. 3 shows a third embodiment of a drag braking device, in which the drive gear of a double-wheel receiving type reel is a cylindrical member with a bottom, and both reel side plates 20 and 21 are parallel to each other by a plurality of supports 22. The spool 23 is held on the spool shaft 2 between both side plates.
It is fixed at 4.

The spool shaft is rotatably supported by a bearing on the side plate 20.21, and a pinion 25 is fitted on the negative side to prevent rotation.

A drive gear 28 that meshes with the pinion 25 is rotatably fitted to the outer periphery of a hollow cylindrical handle shaft 27 that is supported on a fixed shaft 26 of the side plate 20.
The elastic body 4 and the plate-shaped pressing member 5 are fitted into a bottomed cylindrical tube 28a.

The elastic body 4 and the pressing member 5 form a hollow cylindrical handle shaft 27.
is fitted so that it can move freely in the axial direction without rotating in the outer circumferential direction,
The elastic body 4 is configured to be pressed by a drag brake adjustment knob 29 via a pressing member 5 and a spring 11.

A handle 30 is attached to one end of the hollow cylindrical handle shaft 27.
is fixed to prevent rotation, and a reverse rotation prevention gear 31 is fixed to the other end of the shaft 27.

The elastic body 4 and the plate-shaped pressing member 5 are fixed by a protrusion 5a provided on the pressing member as in the previous embodiment.

The third embodiment is constructed as described above, and when the reverse prevention pawl (not shown) is engaged with the reverse prevention gear 31 and the spool 23 is rotated by letting out the fishing line, the drive gear 27 is rotated and the elastic body A frictional braking force acts between the outer circumferential surface of the spool 4 and the wall of the tube 28a, and drag braking is applied to the reverse rotation of the spool 23.

FIG. 4 shows another embodiment, in which a friction material 15 such as Teflon or leather is wound around the outer periphery of the elastic body 4, and the outer periphery of the friction material is brought into contact with the cylindrical wall of the bottomed cylindrical member 3. .

This embodiment can be implemented in addition to the first to third embodiments, and can increase the frictional braking force with the cylinder wall.

In the above description, the present invention is applied to a spinning reel and a double-bearing type reel, but the present invention may be applied to other types of reels.

Since the present invention is constructed as described above, the drag braking member, which was conventionally composed of many parts, is composed of an elastic body and a pressing member, thereby reducing the number of parts and simplifying the assembly work.

Furthermore, the weight is reduced, and the tightening of the drag braking adjustment knob changes the drag braking force linearly with respect to the amount of tightening, making it easy to adjust and providing a strong drag braking force. A drag braking device for a fishing reel can be provided.
