Description

[Detailed description of the invention] This invention relates to a spinning reel for fishing, and more specifically to a spinning reel for inflatable fishing, in which the strength of the drag force applied when the flyer rotates in reverse can be adjusted by the amount of rotation of the handle. The aim is to provide reels for

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Figure 1 shows a cross-sectional view with the drag force adjusted to a weak level using the right handle. A handle shaft 3 having a rectangular cross section is inserted from the side plate 1 side into a square hole along the axis of the main gear shaft 2 so that it can rotate freely, and a nut 4 is attached to a threaded rod on the side of the handle shaft 3 that protrudes from the main gear shaft 2. The handle shaft 3 is prevented from moving in the axial direction by screwing.

The outer circumferential surface of the main gear shaft 2, which is supported horizontally between the left and right side plates 1 and 1', is made to face each other and is slotted to have an oval cross-section, and a round hole is drilled on the outside of the main gear shaft 2. main gear 5
At the same time, the front and back surfaces of the main gear 5 are fitted with round hole drag washers 6-1,
6-2 and an oval hole washer 6-3, and the oval hole washer 6-3 is brought into abutting engagement with a stepped portion formed on the circumferential surface of the main gear shaft 2. movement in the axial direction is restricted so that the clamping operation by the friction member 6 can be performed reliably.

Also, on the outside of the main gear shaft 2,
An inclined cam device 7 is attached, which is composed of a movable cam 8 that rotates integrally with the main gear shaft 2 and a driven inclined cam 9 that freely rotates with respect to the main gear shaft 2. Spring 10 is compressed between the springs 1 and 1.
An elastic force of 0 is applied to the friction member 6 via the inclined cam device 7.
The braking force acts on the reverse rotation of the main gear 5.

The movable cam 8 in the inclined cam device 7 has protrusions 8' and 8'' protruding from its surface facing the driven inclined cam 9, facing each other diametrically, and protrusions 8' and 8'' on the side surface of the driven inclined cam 9. Inclined surfaces 9' and 9'' corresponding to the locus of movement of the fryer 8'' are formed in a circular shape, and the inclined surfaces 9' and 9'' are inclined upward in the forward rotation direction of the fryer, and the respective tops (on the diametrical line ) have protrusions 9, 9 with which the protrusions 8', 8'' of the movable cam 8 abut and engage.
′ is formed protrudingly. Further, ratchet teeth 11 are formed on the circular outer peripheral surface of the driven inclined cam 9.
Moreover, a brake spring 12 is provided on the outermost periphery of the driven inclined cam 9.
, and one of the open ends of the brake spring 12 is fitted and fixed to the main gear 5.

The strength of the elastic force of the spring 10 that presses and biases the tilt cam device 7 can be adjusted using the handle shaft 3.
The amount of compression of the spring 10 is variable by means of an adjustment means 13 consisting of a thread 13' carved on the base side of the spring 10, and an adjustment knob 13'' that is screwed onto the thread 13' and rotates at a fixed position. This allows fine adjustment of the braking force.

In the figure, 14 is the ratchet tooth 1 of the driven inclined cam 9.
The ratchet pawl 14 engages and disengages from the driven tilt cam 9. The pawl 14 is formed into a substantially dogleg shape so that it functions even when the handle is turned left and right and the direction of forward rotation changes.
It is adapted to engage with the ratchet pawl 14 when it rotates in the opposite direction.

15 is a bearing, 16 is a cap, 17 is a sleeve, and 18 is a pinion gear that meshes with the main gear 5.

In FIG. 2, the adjustment knob 13'' of the adjustment means 13 is tightened to slide the handle shaft 3 toward the side plate 1, thereby elastically compressing the spring 10 interposed between the nut 4 and the movable cam 8, and tilting it. This is a state in which the pressing force acting on the friction member 6 via the cam device 7 is strong.

Figure 3 shows a state in which the handle is rotated in the forward rotation direction (direction to wind the fishing line onto the spool) from the state shown in Figure 1, and at the same time as the movable cam 8, which rotates integrally with the main gear shaft 3, slides in the axial direction. The driven inclined cam 9 slides upward on the inclined surfaces 9', 9'' of the driven inclined cam 9, presses the driven inclined cam 9 against the friction member, and the main gear 5 is driven and rotated by the frictional engagement force.

At this time, the driven inclined cam 9 also rotates in the forward rotational direction together with the main gear 5 which is driven and rotated by the frictional engagement force, but the ratchet pawl 14 is raised by the ratchet teeth 11 provided on the driven inclined cam 9.

On the other hand, when the handle is reversed, the movable cam 8 moves toward the bottom side along the inclined surfaces 9' and 9'' of the driven inclined cam 9, and the elastic force of the spring 10 causes the movable cam 8 to move toward the bottom side.
The frictional force that acts on the main gear 5 via the engine becomes weaker, and the braking force that acts on the reverse rotation of the fryer becomes weaker.

In other words, when the fryer rotates in reverse, main gear 5
At the same time as the driven inclined cam 9 is reversed due to the frictional engagement force, the ratchet teeth 11 provided on the cam are also reversed.
is engaged with the ratchet pawl 14, and the reverse rotation of the driven inclined cam 9 is stopped, and the frictional force of the friction member acts on the reverse rotation of the main gear 5.

FIG. 4 is a sectional view showing a state in which the handle has been replaced from the right handle in FIG. 1 to the left handle.

Since the spinning reel for fishing of the present invention has the configuration described in detail above, when the handle is rotated in the forward rotation direction, the inclined cam device rotates integrally with the main gear shaft and simultaneously clamps the main gear. By strongly pressing the friction member, the frictional force acting on the main gear becomes large, and the main gear can be driven and rotated to wind up the fishing line.

Conversely, when the handle is reversed, the force of the inclined cam device that presses the friction member becomes weaker, and as the fryer rotates in the opposite direction, the braking force that acts on the rotation of the main gear, which rotates in the opposite direction, becomes weaker.

Therefore, by adjusting the amount of reversal of the handle, the braking force applied to the main gear when the fryer is reversed can be variably adjusted in a stepless manner, making it possible to fully respond to interactions with fish. .

Furthermore, since a fine adjustment means is provided on the handle separately from the rotating operation of the handle, it is possible to obtain a wide range of braking force by adjusting the hand that rotates the handle.

Therefore, we provide a spinning reel for inflatable fishing that is highly usable, in which the fishing line is wound by rotating the handle in the forward rotation direction, and the fishing line is reeled out by applying a brake to the reverse rotation of the flyer by rotating the handle in the reverse direction. can.
