Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a locking mechanism for a brake adjustment dial in a double-bearing reel, and more particularly to a locking mechanism for a brake adjustment dial that applies a brake to the rotation of a spool by magnetic force.

(Prior art) In a double-bearing reel, a brake device that applies a braking force to the rotation of the spool by magnetic force is as follows:
A disk holding a magnet is placed on the outside of the side plate of the spool, which is rotatably supported between the left and right side frames, and the disk controls the rotation of the adjustment dial, which is rotatably attached to the side frame. The braking force is moved in the axial direction via a cam mechanism or the like, and the distance between the spool side plate and the magnet is varied to adjust the strength of the braking force.

However, this double-bearing reel, especially a baitcasting reel, is operated by palming (holding the fishing rod with the left hand so as to wrap around the side frame opposite the reel handle), so the palming left hand is attached to the side frame. If you touch the adjustment dial of the attached brake and change the setting position of the adjustment dial without knowing it, there is a risk of injury.

Conventionally, in such a brake device, there is no locking mechanism that prevents the adjustment dial from rotating even if the dial is inadvertently touched.

(Problems to be Solved by the Invention) In view of the above-mentioned conventional circumstances, the present invention aims to prevent the dial from rotating even if the palmed hand touches the adjustment dial on the side frame.

(Means for Solving the Problems) The technical means of the present invention for solving the above problems is to form teeth on the outer peripheral surface of the adjustment dial, and mesh with the teeth on the outside of the adjustment dial. A lock button having an engaging tooth portion is disposed so as to be slidable in the axial direction, and the lock button is biased by a spring in the engaging direction.

(Function) For the teeth formed on the outer circumferential surface of the adjustment dial,
The engaging teeth of the lock button, which are pressed outward by the spring, are engaged, preventing rotation of the adjustment dial. By pressing the lock button downward against the elastic force of the spring, the lock button can be engaged. The teeth are disengaged from the teeth, and as a result, the adjustment dial becomes freely rotatable, and when the lock button is released, it is pushed upward by the elastic force of the spring, and the engaging teeth mesh with the teeth again.

(Embodiment) An embodiment of the present invention will be described below based on the drawings. Fig. 1 shows a double-bearing reel equipped with the device of the present invention, in which a spool 3 is rotatably mounted between the left and right side frames 1 and 2. The spool 3 is mounted on one side frame 1.
A gear power mechanism, a clutch mechanism (not shown), etc. for driving and rotating the spool 3 are housed therein, and the spool 3 is rotated by the rotation of the handle 4 to freely rotate the spool 3. A brake device A is provided for applying the brake.

The brake device A is composed of a disc 6 on which magnets 5 are arranged and fixed, a slide cam 7 that firmly holds the disc 6 and slides in the spool axis direction, and an adjustment dial 8 that slides the slide cam 7. There is.

A disk-shaped permanent magnet is used as the magnet 5,
The magnets 5 are arranged on one side of a ring-shaped disk 6 so that their magnetic poles alternate, and two sets of magnets are arranged and fixed symmetrically on the circumference.

The disc 6 is housed in a space a defined by the spool cover 2b fixed to the side plate cover 2a of the side frame 2 and the outer surface of the spool 3, and the magnet 5
is stored so as to face the outer surface of the spool 3,
The disc 6 is located symmetrically with respect to the center of the spool cover 2b and has two leg rods 10 of a slide cam 7 that can protrude through the through hole 9 into the space a.
It is fixed with a screw at the tip.

The slide cam 7 is formed of a synthetic resin material in the shape of a disk, with protruding pieces integrally protruding from both sides of its diameter, and a leg rod 10 integrally formed on the protruding pieces. A through hole that fits into the core rod 11 protruding from the center of the spool cover 2b is drilled, and around the through hole is an annular shape in which a compression coil spring 12 is installed to be elastically installed between the spool cover 2b and the spool cover 2b. A groove 13 is formed. Further, on the other side of the slide cam 7, that is, on the side opposite to the side where the leg rod 10 is provided, two inner and outer inclined cam lines 14, 15 are formed concentrically protruding, and both inclined cam lines 14, The effective range of 15 is symmetrically arranged at 280 degrees.

The adjustment dial 8 for sliding the slide cam 7 is made of synthetic resin and has a disk shape.
Two inner and outer inclined cam lines 16 and 17 corresponding to the inner and outer two inclined cam lines 14 and 15 of the slide cam 7 are formed concentrically on one side thereof, and
The inclined cam line 1 is provided on the outside of the outer inclined cam line 17.
A cylindrical wall surrounding the lock button 7 is integrally formed, and a toothed portion 18 is formed on the outer peripheral surface of the cylindrical wall, and a lock button 19 is attached to the engaging toothed portion 20 of the lock button 19 so as to be movable in and out of the side plate cover 2a. Sound producing claws 21 attached to the sides are engaged.

The lock button 19 has a cylindrical shape and has a protruding engaging tooth portion 20 on the outer peripheral surface of the lower part, so that it can freely engage with the tooth portion 18 of the adjustment dial, and the lock button 19 is prevented from rotating on the outer surface of the cylindrical peripheral wall so as to protrude and retract in the axial direction. The guide protrusion 22 is fitted into the guide groove 23, and a coil spring 24 is elastically attached between the side plate 2c and the inner bottom surface of the lock button 19, so that the spring 24 is always elastically biased upward. 18 and the engaging tooth portion 20 mesh with each other to prevent the adjustment dial 8 from rotating.

To install the adjustment dial 8 above, please use the side plate cover 2.
It is fitted from the inside into the opening 25 formed in the side plate cover 2a, and the protruding edge on which the teeth 18 are formed engages with the opening edge to prevent it from coming off outward. A recessed notch 26 is formed so that the rotation operation of the adjustment dial 8 can be controlled by the recessed notch 26.
It is designed so that it can be easily performed by placing your finger on it.

With the above configuration, when variably adjusting the braking force with respect to the rotation of the spool 3, the lock button 19 is pushed down against the elastic force of the spring 24, and the engaging tooth portion 2
Adjustment dial 8 by removing 0 from tooth part 18
can be freely rotated and adjusted to a desired position, and when the lock button 19 is released from the lock button 19 after the adjustment is completed, it is pushed upward by the elastic force of the spring 24, and the engaging teeth 20 mesh with the teeth 18. This prevents the adjustment dial 8 from rotating.

In addition, in the above embodiment, the adjustment dial 8
The tooth portion 18 that engages with the engaging tooth portion 20 of the lock button 19 that regulates the rotational movement of the adjustment dial 8 is also used for engagement with the sound pawl 21 that moderates the rotational movement of the adjustment dial 8. Sound output claw 21
Of course, the teeth 18 and the interlocking teeth 20 may each mesh with independent teeth, and the shapes of the teeth 18 and the engaging teeth 20 are not limited to the shapes shown, but may be square teeth, round teeth, or the like.

(Effects of the invention) As described in detail above, the locking mechanism of the brake adjustment dial of the present invention includes teeth formed on the outer circumferential surface of the adjustment dial, and engaging teeth that mesh with the teeth on the outside of the adjustment dial. The lock button is disposed so as to be slidable in the axial direction, and the lock button is biased by a spring in the direction of engagement, so that it can be pushed outward by the spring against the teeth formed on the outer circumferential surface of the adjustment dial. Since the engaging teeth of the pressed and energized lock button are engaged, rotation of the adjustment dial is prevented, and by pressing the lock button downward against the elastic force of the spring, the engaging teeth of the lock button are engaged with the teeth. As a result, the adjustment dial becomes freely rotatable, and when the lock button is released, it is pushed upward by the elastic force of the spring, and the engaging tooth portion meshes with the tooth portion again.

Therefore, the adjustment dial can be rotated and locked with one-touch operation, and the adjustment dial will not rotate unless the lock button is pressed down, so even if the palming hand grips the side frame, the adjustment dial will not move. If you rotate it carefully, there is no danger at all.
