Abstract

PURPOSE:To stabilize the braking action of a reel-braking apparatus over a long period under a severe condition liable to cause the contamination with seawater, sand, etc., and to improve the durability of the apparatus by using a rolling member as a rear-drag type braking member of a spinning reel for fishing. CONSTITUTION:A spool 4 is fixed at the tip end of a spool shaft 5 of a spinning reel for fishing and a rotary member 8 is rotatably supported on the rear part of a reel casing 1. The rear part of the spool shaft 5 is inserted into the rotary member 8 in a state freely movable exclusively in axial direction to enable the integral rotation of the parts. A non-rotating member 12 is integrated to a cylindrical part 10 protruded from the rear end of the reel casing 1 in a state movable exclusively in axial direction. A rolling member 13 is placed between tapered circumferential surfaces 9, 11 formed on the opposite parts of the rotary member 8 and the non-rotating member 12. The position of the non-rotating member 12 in the axial direction is adjusted by a braking power controlling knob 14 screwed into the cylindrical part 10. The braking power to the reverse rotation of the spool shaft 5 can be controlled by adjusting the rolling and sliding friction resistance of the rolling member 13.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a spinning reel for fishing, particularly a rear drag type braking device.

[0002]

2. Description of the Related Art As a rear drag type braking mechanism for spinning reels for fishing, for example, the actual open sho 63-1517.
As disclosed in Japanese Laid-Open Patent Publication No. 60 and Japanese Utility Model Laid-Open No. 62-164774, a plurality of braking plates such as linings are superposed and fitted between the outer peripheral portion of the spool shaft and the inside of the tubular portion formed on the reel casing. The present situation is to utilize the frictional resistance effect on the spool shaft due to pressing.

[0003]

However, since the spinning reel for fishing is used under severe conditions in which water such as seawater, sand, dust, etc. are likely to adhere, the spinning reel for conventional products is In the braking method using the pressure contact of the brake plates, there are problems that the braking efficiency is reduced, the brake plates are corroded, and the durability and strength thereof are deteriorated, so that a stable braking function cannot be maintained for a long period of time. In view of these circumstances, an object of the present invention is to provide a braking device for a spinning reel for fishing, which is capable of always performing a stable spool braking action even under severe conditions where moisture, sand, dust, etc. easily adhere. To do.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention mounts a rear portion of a spool shaft having a spool integrally provided at a front end thereof only in an axial direction and rotates the rear portion of a reel casing. A rotating member movably supported and a non-rotating member axially freely engaged with a cylindrical portion projecting from the rear portion of the reel housing are arranged in a superposed state, and the rotating member and the non-rotating member are arranged. The opposing portions of the respective are formed on the tapered peripheral surface, and a rolling member is interposed between them, and further, a braking force adjusting knob for restricting the axial position of the non-rotating member is fitted on the cylindrical portion. It is a thing.

[0005]

When the spool shaft, which is integral with the spool, tries to rotate in the reverse direction due to the tension of the fish during the fishing operation, the rotation member that rotates integrally with the spool shaft and the tubular portion of the reel housing are held so as not to rotate. The rolling member interposed between the tapered peripheral surfaces of the non-rotating member controls the reverse rotation of the spool shaft by the rolling and sliding frictional resistance due to the taper screw action, and the braking force adjusting knob is used to control the axial direction of the non-rotating member. Is regulated to control the braking force of the rolling member in a strong and weak manner.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.
A rotor 2 is provided at the front of the reel housing 1 of the spinning reel.
Is supported in the reel housing 1 of the spool shaft 5 while a spool shaft 5 having a spool 4 fixed at its tip is rotatably and slidably inserted in the barrel 3. The rotatably fitted slider 6 engages with the traverse cam shaft 7 which is interlocked with the shaft cylinder 3, and rotates the rotor 2 by rotating the handle shaft as well as rotating the spool shaft 5 back and forth as is well known. The fishing line is reciprocally moved to wind the spool 4 around the spool 4.

The rear portion of the spool shaft 5 is formed into a truncated circular shaft portion 5 ', and the truncated circular shaft portion 5'is freely axially movable by a rotary member 8 rotatably supported on the rear portion of the reel housing 1. The outer peripheral surface of the rear portion of the rotary member 8 is formed into a tapered peripheral surface 9 having a locking portion 9 '. Further, a cylindrical portion 10 having a concave-convex strip 10 'is provided on the rear side of the reel casing 1 in the axial direction of the inner peripheral surface thereof. Inside the cylindrical portion 10, a taper shape facing the tapered peripheral surface 9 is formed. A non-rotating member 12 is provided which forms a peripheral surface 11 and engages with the concavo-convex strip 10 'and is movable only in the axial direction, and a cylindrical rolling member 13 is provided between the opposed tapered peripheral surfaces 9 and 11. Further, a braking force adjusting knob 14 is screwed on the outside of the cylindrical portion 10, and is configured to be able to adjust the axial position of the non-rotating member 12 via a spring 15 by advancing and retracting the same. There is. In the figure, 16 is a holding frame for the rolling member 13.

Therefore, when the spool shaft 5 reversely rotates together with the spool 4 due to the load of the fishing line, the rotary member 8 which rotates integrally with the spool shaft 5 also tries to reverse, but the rotary member 8 and the tubular portion 1 also rotate.
As shown in FIG. 3, the rolling member 13 disposed in the tapered gap between the tapered peripheral surfaces 9 and 11 of the non-rotating member 12 which is engaged with 0 and is prevented from rotating has its axial center. The taper screw action due to the slanted arrangement with respect to the shaft causes the locking portion 9'to restrict the axial movement while rolling and moving in the direction of the arrow, resulting in rolling and sliding friction resistance. The braking force adjusting knob 1 is for braking the reverse rotation of the souple 4 that rotates integrally with the rotating member 8 that is about to rotate due to the feeding of the fishing line.
By controlling the axial position of the non-rotating member 12 by advancing and retreating 4 to adjust the tapered gap between the tapered peripheral surfaces 9 and 11, the rolling and sliding frictional resistance of the rolling member 13 is strongly controlled. It adjusts the spool braking force.

[0009]

INDUSTRIAL APPLICABILITY The present invention is a rear drag dip for a spinning reel for fishing, in which a spool shaft is freely inserted only in the axial direction and is rotated integrally with a rotating member and a tubular portion of a reel housing, which is freely rotatable only in the axial direction. A tapered peripheral surface is formed in a portion facing the non-rotating member engaged with the wheel member in a non-rotatable manner, and a rolling member is interposed between the tapered peripheral surfaces, and the rolling member is interposed by the rolling and sliding friction resistance of the rolling member. Since the spool shaft is controlled to brake the reverse rotation of the spool, the rolling member can maintain a stable braking function for a long period of time even under severe conditions where seawater, sand, dust, etc. easily adhere. It has an excellent feature that it is possible to improve the defect due to the pressure welding of the conventional braking plate.
