JPS5929202B2 - Fishing spinning reel spool reciprocating device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION Conventional spinning reel spool reciprocating sliding mechanisms are disclosed in, for example, Japanese Utility Model Publication No. 29-11171 and Japanese Utility Model Publication No. 29-16.
As seen in Publication No. 456, since the constant angular velocity interlocking of the rotor drive gear is converted into reciprocating motion, the reciprocating motion of the spool becomes an inconstant motion as shown in line C in Figure 3, and therefore the winding on the spool is As shown in FIG. 5, the surface of the fishing line is wound in an uneven shape with bulges on the left and right portions and depressions in the center.

However, when the fishing line winding surface exhibits an uneven shape as described above, when the fishing line is let out from the spool, the frictional resistance between the fishing lines prevents the hook from being cast far, reducing the long-distance casting effect.

In order to improve this defect, the cross section of the fishing line winding body of the spool has been made to bulge out in the shape of a drum, but this is currently only a makeshift solution.

The present invention is a spinning reel in which the spool of the spinning reel is reciprocated in substantially constant motion, and the fishing line is wound flatly on the winding surface of the spool, thereby improving the effect of long casting when the fishing line is reeled out.
One of a pair of internal gears that mesh with each other with their long axis axes perpendicular to each other every time it rotates 0 degrees is fixed to a bundle shaft to which a large gear for driving a rotor is fixed, and the other is driven by an elliptical gear. is pivotally supported in the reel housing, and a crank pin is provided in a direction that substantially coincides with the minor axis of the driven elliptical gear and integrally with the inner gear, and the crank pin is orthogonal to the spool sliding axis. The gist of this is that it fits into a guide groove provided as a guide groove.

An embodiment of the present invention will be described with reference to the drawings. A shaft is rotatably supported in a shaft housing 2, and includes:
A rotor driving large gear 3 is fixed to the tip inside the reel housing 2, and the gear 3 meshes with a small gear 6 and a mesh 6 provided on the shaft cylinder 5 of the rotor 4, and the rotation of the bundle shaft 1 drives the rotor. It is configured to rotate 4.

Further, a barrel internal gear 1 is fixed to the reel shaft 1 in the reel housing 2 so as to face the rotor driving large gear 3, and the barrel internal gear 1 is similarly supported by the reel housing 2. The tank internal gear 8 meshes with the tank internal gear 8 in such a manner that their major axes are perpendicular to each other every time it rotates 90 degrees, and a disc 9 is integrally provided at the front end of the tank internal gear 8. A crank pin 10 is provided on the peripheral surface of the plate 90 to protrude in a direction that substantially coincides with the minor axis of the tank internal gear 8.

A spool sliding shaft 12 having a spool 11 at its tip is slidably inserted into the shaft cylinder 5, and a guide rod 13 provided perpendicularly to the distal end of the spool sliding shaft 12 is guided. The crank pin 10 is fitted into the groove 14, and a rotating handle 16 having a handle 15 is provided at the outer end of the bundle shaft 1Ω.

Since the embodiment of the present invention is constructed as described above, rotation and
- When the handle shaft 1 is rotated by the handle 16, the spool 11 becomes a gear in the column? , 8, disc 9, crank pin 10,
The spool slide shaft 120 is reciprocated through the guide groove 14 and the spool sliding shaft 12, and the stroke of the spool sliding shaft 120 performs an approximately uniform reciprocating motion that substantially coincides with the constant velocity motion line B as shown in the line A in FIG. As shown in FIG. 4, the fishing line is wound onto the spool 11 with its winding surface flattened by the rotor 4 which is rotated through the rotor driving large gear 3 and small gear 6.

In order to reciprocate the spool shaft on the handle shaft, the present invention uses a pair of gears in the field that mesh with each other with their major axes perpendicular to each other every time the spool shaft rotates 90 degrees. Since the crank pin fitted into the guide groove is installed in a direction that substantially coincides with the minor axis of the driven field gear and is integral with this, the spool moves at an approximately uniform constant speed due to the rotation of the bundle rotating shaft. It has the excellent feature of being able to move and wind the fishing line flatly on the spool as shown in Figure 4, thereby reducing the abrasion resistance between the fishing lines that occurs when the fishing line is fed out, and allowing the fishing tackle to be thrown over long distances. It is.
