Description

[Detailed Description of the Invention] The present invention relates to a spool sliding mechanism in a fishing spinning reel.

As shown in FIG. 1, the above-mentioned reel is formed by supporting a reel body 1, with a rotor 2 rotatably supported by a tube shaft, and a spool 3 supported by a spool shaft 4 so as to be reciprocating in the front and back direction. The rotor 2 rotates via the pinion gear 20 by the rotational force of a handle shaft (not shown) being transmitted, and the spool 3 reciprocates to spool the fishing line (not shown) hooked onto the bail arm 6 of the rotor 2. It is well known that the paper is configured so that it can be rolled up in parallel to 3.

The spool 3 is reciprocated in the front and back direction by a sliding mechanism 7 for converting the rotational force of the handle shaft (not shown) into linear reciprocating motion. A slider 9 is provided with an endless spiral groove 8a carved on the outer periphery of one end of the sliding gear 8 that rotates in response to rotation, and an engaging element 9a that engages with this groove is fitted in a swingable manner. The engagement element receives the rotational force of the endless spiral groove 8a, and is capable of reciprocating the length of the stroke of the endless spiral groove 8a, and is prevented from rotating by the rotation prevention means 10 of the slider. A slider 9 is provided.

It is known that the spool shaft 4 is fixed near the rear end of the slider with a pin 15 or the like.

However, in the conventional device, as shown in the figure, the anti-rotation means 10 of the slider 9 has an arm 11 protruding from the slider 9 and engages with a guide portion 12 provided on the reel body 1 or other members. Since it is formed to slide in the front-rear direction, if the distance that the detent means 10 reciprocates becomes long, the arm 11 of the slider 9 will also move a long distance. By enlarging the reel body 1, the arm 11 of the slider 9 cannot be accommodated unless the reel body 1 is made vertically elongated. Therefore, the reel must be made larger in order to increase the stroke, which increases the weight of the reel. There was a problem in that it became difficult to perform long-distance casting operations during cast fishing.

Therefore, as a result of studies in view of the above-mentioned conventional circumstances, the present invention has been developed to create a new sliding mechanism for a spinning reel.The purpose of this invention is to increase the sliding stroke without increasing the size of the reel body. This is because the structure is simple and easy to manufacture.

The present invention will be described in detail below based on illustrated embodiments.

For convenience of explanation, the same reference numerals as in the above-mentioned conventional example indicate the same members in the drawings and explanatory text.

As shown in FIGS. 1 to 4A and B, a sliding gear 8, which has an endless spiral groove 8a on its outer periphery, receives the rotational force of a handle shaft (not shown). The rotation causes the endless spiral groove 8a to rotate, and the endless spiral groove 8a to rotate.
The slider 9, in which the engager 9a that engages with the slider 9 is fitted in a swingable manner, is fitted and sheathed. The sliding gear 8 is provided at opposing positions on the same axis of the pinion gear 20 and the spool shaft 4, and is rotatably supported in a sliding gear mounting hole 1e provided in the reel body, and its axial movement is limited to the front. The direction side is the pinion gear 20, and the rear direction side is immovably provided by the wall surface perpendicular to the axial direction of the sliding gear mounting hole 1e, so that the slider can be moved by the rotation of the endless spiral groove 8a. 9 performs reciprocating sliding along the axis, which is the same as in the conventional example.

In the present invention, the slider 9 is formed into a long hollow polygonal or non-perfect circular shape, and is non-rotatably and slidably engaged in the axial direction of the guide tube 13 fixed to the rear part of the reel body 1. It is fitted.

The guide tube 13 has a guide hole 13a for the slider 9 formed through the shaft center in a hole that fits the outer shape of the slider 9, a threaded portion 13b on the outer periphery, and a reel on the inner end. Each of them is provided with an outward flange 13c having a rotation prevention function that fits the shape of the inner rear portion of the main body 1, and the length thereof is formed to be considerably shorter than that of the slider 9. .

That is, the guide tube 13 has a circular outer shape, and the outward flange 13c is connected to the reel body 1.
It is engaged with a protrusion that engages with the outward flange 13c of the guide tube 13 to prevent rotation of the guide tube 13, such as a screw fixing protrusion 1b of the lid (not shown) provided on the rear wall 1a of the It is rotationally fitted into the mounting hole 1c.

Further, the sliding gear 8 insertion hole 9b of the slider 9 is of course provided with a circular cross section, and the outer shape and the guide hole 1 in the guide tube 13 are
The shape of 3a may be a polygon such as a square, pentagon, or hexagon, or any shape other than a perfect circle such as a circular shape or an oval shape, in which both can be engaged non-rotatably and slidably in the axial direction. Bye.

In this way, the guide tube 13 is inserted from the inside into the mounting hole 1c formed through the rear wall 1a of the reel body 1, and the outward flange 13c is fitted and crimped to the rear inside of the reel body 1, and the threaded portion protrudes to the outside. 13b
It is fixed to the reel body 1 by screwing the screw cap 14 onto the reel body 1, and the slider 9 mounted on the sliding gear 8 is fitted into the guide hole 13a of the guide tube 13 to prevent rotation. The sliding mechanism is configured such that the portion of the spool shaft 4 protruding from the rear end of the sliding gear 8 and the rear end of the slider 9 are fixed with a pin 15 or the like. Assembled and configured.

As explained above, according to the sliding mechanism of the spinning reel according to the present invention, the slider 9 is formed into a hollow polygonal or non-circular shape, and the guide is fixed to the rear mounting hole 1c of the reel body 1. By inserting it into the guide hole 13a of the cylinder 13, which has a shape that matches the outer shape of the slider 9, it is installed non-rotatably and slidably in the axial direction. There is no need to protrude the arm 11 into the reel body 1 to prevent the slider 9 from rotating, and the end surface of the slider 9 on the engagement element side is attached to the rear wall surface of the sliding gear mounting hole 1e of the reel body 1. The sliding stroke can be extended from the position where the slider 9 is inserted to the position where the rear end face of the large diameter part and the front end face of the outward flange 13c of the guide tube 13 are in contact with each other. Therefore, there is no need to make a large body mold, and by drilling a mounting hole for the rear guide tube 13 of the conventional reel body 1, the reel body 1 can immediately have a large stroke, and the slider 9 can be attached to the guide tube 13. The slider is fitted and protruded to the rear of the reel body 1, and the rotation stopper of the slider has a non-perfect circular shape and a polygonal shape, and since the arm 11 is not provided, the space for movement of the arm portion 11 is unnecessary.
It is possible to increase the sliding stroke within the already determined profile without having to make it large, and it is useful for making the reel smaller and lighter, or for sharing large and small strokes with the same reel body 1. It is valid.

In addition, the guide tube has a length that can be tightened and fixed with the screw cap 14 in accordance with the rear inner shape of the reel body 1, and can be easily and reliably assembled in the specified direction. can do.
