Description

[Detailed description of the invention] [Industrial field of application] The invention is a drag mechanism for a spinning reel for fishing, more specifically, a spool is fixed to the front end,
The present invention relates to a rear drag mechanism in which the rear end portion of a main shaft supported on the reel body so as to be reciprocated in the front-rear direction extends to the rear portion of the reel body, and is provided at the rear portion of the reel body in association with the extending portion.

[Prior Art] A conventional rear drag mechanism of this type is disclosed in Japanese Utility Model Application No. 59-42169. According to this configuration, the annular spring is housed in a cylindrical body that is located at the rear of the housing and has a drag washer installed inside the cylindrical body. By interfering with the uneven stripes provided on the inner side of the handle tube provided so as to cover the handle tube, a click feeling and loosening of the handle tube when rotating is provided. However, in such a structure, since the protrusion protrudes from the inside of the barrel toward the handle tube side, it is necessary to increase the outer diameter of the uneven stripes of the handle tube in order to maintain the strength of the uneven stripes. The position where the annular spring interferes with the uneven surface is located at a position that is spaced apart from the position of the tightening screw that fastens the handle tube and the adjustment body. Further, an adjustment body was screwed onto the cylindrical body, and a handle tube having an uneven shape was further fitted into the adjustment body and screwed with a tightening screw.

[Problems to be solved by the invention] In the configuration of the conventional rear lug mechanism as described above, the annular spring interference part of the handle tube must be thick enough to withstand the impact force caused by the collision of the annular spring. Not only does the outer diameter of the hand tube become larger, which impairs the overall size, weight, and smartness of the reel, but also because the interference position between the annular spring and the uneven surface is far away, the impact caused by the interference increases the amplitude of the handle tube, causing the tightening screw to become tighter. Not only does the handle become loose, making it easy for the handle to fall off, but since the adjustment body is screwed onto the cylinder and the uneven handle is screwed onto this adjustment body with a tightening screw, it does not hold against the cylinder. The concentricity of the concave and convex strips on the handle tube tends to be out of alignment, and therefore the sound generated when the annular spring collides with the concave and convex strips tends to vary, becoming louder or quieter. The concave groove of the adjustment body fits into the protrusion of the annular spring,
Another problem is that assembly is difficult because the adjusting body and handle tube are fitted at both fitting positions and screwed together with a tightening screw.

The present invention was devised in consideration of these points, and its purpose is to provide a sense of moderation to the rotation of the drag knob, prevent it from becoming loose, and expand the adjustment range of the drag, as well as to make the drag noise. The object of the present invention is to stabilize the drag knob, facilitate assembly, reduce the size of the drag knob, and prevent the drag knob from falling off due to loosening of its screws.

[Means for Solving the Problem] In order to achieve the above object, a concave and convex portion is provided in the circular portion of the drag control screw, and a click spring that is externally fitted into the cylindrical portion is fitted so as to be elastically deformable in a semicircular direction. The protruding end portion thereof is configured to resiliently engage with the concave portion and the convex portion.

[Function] Since the protruding end of the click spring is elastically engaged with the concavo-convex portion of the drag control screw from the outer periphery of the cylindrical part through the opening, no impact force is applied to the drag knob, so it is only necessary to have the minimum wall thickness. It is easy to maintain concentricity between the cylindrical part and the drag control screw, so the drag sound is stable, and after the drag control screw is screwed into the cylindrical part, the click spring is assembled into the cylindrical part, so even if there is a recess in the drag control screw, the click spring can be assembled into the cylindrical part. Even if it is a convex part, the click spring can be fitted, so assembly is easy.

Due to the elastic force of the click spring, the impact force is generated at the concavo-convex portion provided in the immediate vicinity of the male threaded portion that screws into the cylindrical portion of the drag control screw, so the impact force is absorbed by the male screw and the female thread of the cylindrical portion. Further, the drag control screw is prevented from rotating by engaging with the concavo-convex portion of the protruding end of the click spring.

[Embodiment] The present invention will be described in detail below based on the illustrated embodiment. First, as shown in FIGS. It is freely supported by a tube shaft (not shown), and a main shaft 3 is passed through the tube shaft so as to be able to reciprocate back and forth.
A spool 3 is fixed to the front end of the spool 3, and a main gear (not shown) is rotated by rotating a handle 5 that is pivotally supported on the reel body 1, and the rotor 2 is rotationally driven. The spool 4 is reciprocated in the front and rear directions by an oscillating mechanism (not shown), so that the fishing line (not shown), which is hung around the bail arm roller 6 provided on the rotor 2, is wound around the spool 4. It is configured.

Further, the rear end portion 3a of the main shaft 3 has a through hole 1b provided through the rear wall 1a of the reel body 1.
a cylindrical portion 7 extending rearward through the reel main body rear wall 1a and integrally protruding rearward from the reel main body rear wall 1a;
The drag mechanism 8 is provided at the rear of the reel body 1 so as to protrude from the center of the interior of the reel body 1 and apply a drag force to the rear end 3a.

The drag mechanism 8 of the present invention is constructed as follows.

As shown in FIGS. 2 to 4, a female threaded portion 7a is formed on the inner periphery of the open end of the cylindrical portion 7, and a male threaded portion 7a is formed on the outer periphery of the base. By screwing together the threaded portion 9a, the drag control screw 9 is screwed into the cylindrical portion 7 so as to be able to be screwed forward and backward in the axial direction, and the drag control screw 9 and the rear end portion of the main shaft 3 are screwed together. A drag spring 11 is interposed between the drag washer 10 which is externally mounted on the cylindrical portion 3a and a drag washer 10 which is internally mounted on the cylindrical portion 7.

Here, the drag washer 10 is externally mounted on the rear end 3a of the main shaft 3 in a state in which a plurality of washers are stacked one on top of the other in the axial direction.
In reality, the rear end portion 3a is formed into a substantially oval shape in cross section, and a click 12 having an oval inner diameter is mounted on the rear end portion 3a to correspond to this, and the outer shape of the click 12 is also changed. The drag washer 10 is formed into a substantially oval shape in cross section, and the inner diameter of one of the plurality of drag washers 10 is made into an oval shape, and by fitting into the click 12, it can be fixed in the axial direction and slid only in the axial direction. Another drag washer is mounted on the click 12 so as to be able to rotate and slide around the axis and in the axial direction, and furthermore, at the base of the click 12,
An outward flange 12a is provided to receive the drag washer 10, and the thrust of the drag control screw 9 is transmitted to the drag washer 10 via the drag spring 11.
The repulsive force of 1 is from drag washers 10 to click 1.
2 to the main shaft 3 to generate a drag force on the spool 4.

Further, the drag control screw 9 is formed in a substantially horizontally convex shape in its longitudinal section, and has a smaller diameter on the tip side than the male threaded portion 9a provided on the outer periphery of its base. The outer shape is formed into a rectangular, pentagonal, hexagonal or other external angular part 9b, and by fitting the mounting hole 13a into the polygonal part 9b and fixing it with the screw 14, the drag knob 1 is fixed.
3 is fixed with a drag control screw 9.

Therefore, the mounting hole 13a of the drag knob 13 is naturally formed into a polygonal shape corresponding to the polygonal portion 9b of the drag control screw 9.

The drag knob 13 has an end wall 13b and a peripheral wall 13c, each having a substantially horizontal cup shape in vertical section, and the mounting hole 13 is formed in the center of the end wall 13b.
a is recessed, and a fitting hole 13d is provided at the tip of the recess.
is inserted through the drag control screw 9 and fitted into the tip of the drag control screw 9, and both are fixed concentrically by screwing the screw 14 into the screw hole 9c of the drag control screw 9 at the center position. ,
The peripheral wall 13c covers the cylindrical portion 7 together with the drag control screw 9.

Further, a circular portion 9d is formed between the male threaded portion 9a and the polygonal portion 9b of the drag control screw 9, and a recessed portion 15a and a convex portion 15b are formed on the outer periphery of the circular portion 9d in the circumferential direction. The cylindrical portion 7 is provided with concave and convex portions 15 alternately provided.
A click spring 16 is supported in a compressed state toward the center at a position facing the uneven portion 15 on the edge of the opening, and projecting ends 16a, 16b, 16b are bent inwardly from the click spring 16.
is resiliently engaged with the concavo-convex portion 15, and by rotating the drag control screw 9 with the drag knob 13, the click spring 16
The annular portion 16c is elastically deformed by its own elastic force, and the protruding ends 16a, 16b, 16b climb from the recess 15a onto the convex portion 15b, and then the recess 15a
The drag knob 13 is configured to resiliently engage with the drag knob 13 to generate a clicking sound, and to rotate the drag knob 13 with a sense of moderation.

Here, the click spring 16 is formed by bending a spring material into an annular shape, and bending both ends of the spring material inward to form the protruding end portions 16b, 16b.
It is preferable to use a structure in which the opposing portions of the projecting ends 16b, 16b are curved inward in a substantially V-shape from the front to provide the projecting end 16a. An annular groove 7b is provided around the outer periphery of the opening edge of the cylindrical part 7 as shown in FIG. 5, and the opposite part of the annular groove 7b is notched in the axial direction to open at the tip of the cylindrical part 7. Openings 7c, 7c are provided oppositely, and the annular portion of the click spring 16 is fitted into the annular groove 7b, so that the protruding ends 16a, 16b, 16b are connected to the openings 7c, 7.
The annular portion 16c is fixed in the circumferential direction and the axial direction by being engaged with the annular portion 16c, and is supported on the cylindrical portion 7 so that the annular portion 16c can be elastically deformed in the radial direction.

Therefore, when adjusting the drag force by rotating the drag control screw 9 together with the drag knob 13,
Projecting ends 16a, 16b, 1 of click spring 16
6b receives rotational force due to the uneven portion 15, but the click spring 16 is prevented from moving around the axis and in the axial direction as described above, so that it is elastically deformed only in the radial direction at a predetermined position. It is possible to ride over or engage with the portion 15.

[Effect of the invention] According to the drag mechanism of the fishing spinning reel of the invention, the circular portion 9b of the drag control screw 9
A concave and convex portion 15 consisting of a concave portion 15a and a convex portion 15b is provided in the cylindrical portion, and a click spring that is fitted onto the cylindrical portion is fitted so as to be elastically deformable in a semicircular direction, so that its protruding end 16a is elastically engaged with the convex portion of the concave portion. Since the projecting end portion 16a is configured to fit together, it is possible to easily incorporate the protruding end portion 16a into either the recessed portion 15a or the convex portion 15b.
Since the cylindrical part and the drag control screw are directly screwed together, the cylindrical part and the drag control screw are easily concentric with the cylindrical part. Since the outer periphery of the drag control screw 9 resiliently engages with the concave and convex portion 15 of the internally installed drag control screw 9, the impact caused by the resilient force accompanying the rotation for adjustment of the drag is absorbed by the external threaded portion 9 screwed into the cylindrical portion 7.
a. The screw 14, which is absorbed by the female screw 7a of the cylindrical portion 7 and screws the drag control screw 9 and the drag knob 11, does not loosen, so the drag knob does not fall off, and the click spring resiliently engages with the drag knob. Since the drag knob is not a small piece, the size of the drag knob can be reduced to the minimum necessary wall thickness, making it more compact.It has a good balance with the reel body and can be made smaller overall.Also, the drag knob does not have to be thick and large, so it is lightweight. It is possible to achieve a special effect of realizing the
