Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a spool for a spinning reel, and more specifically, a winding drum whose outer peripheral fishing line winding surface is inclined with respect to the axis, and a pair of winding drums provided at both ends of the winding drum. This invention relates to a spool for a spinning reel consisting of a flange.

(Prior art) In general, this type of spool can reduce the pulling resistance of the fishing line during casting and increase the flying distance, but when winding the fishing line on the winding surface,
The fishing line of the first and second plies easily slips in the axial direction on the winding surface, and this slipping of the fishing line causes the winding part to become slack, so the fishing line is wound onto this slack part. Then, when casting,
There was a problem in that the fishing line on the outer side of the slack portion bundled up and pulled out from the spool.

Therefore, conventionally, as described in Japanese Utility Model Application Publication No. 55-68469, a large number of annular grooves or twills are formed on the entire circumferential surface of the winding surface, which are displaced in the circumferential direction from one side in the axial direction to the other side. It has been proposed to provide grooves to prevent the fishing line from slipping.

(Problem to be solved by the invention) However, according to the spool provided with the annular groove or twill groove as described above, if the fishing line is wound in accordance with the inclination angle of the uneven grooves formed by the groove, the anti-slip effect can be achieved. However, if the winding angle of the fishing line deviates from the inclination angle of the streaks, the fishing line wound with an inclination angle different from the inclination angle of the streaks will fall on the convex portion between the grooves located in the circumferential direction and the axial direction. Moreover, the fishing line that has climbed onto the convex portion will not slip down on the thread, so the fishing line wrapped at the above-mentioned winding angle will not be prevented from slipping. No effect can be obtained. In other words, in known spinning reels, since the winding direction of the fishing line is not constant, the fishing line may be wound at an angle deviated from the annular groove or the twill groove. It cannot be stopped for sure. Further, when the twill grooves are provided, the twill grooves are densely formed over the entire surface of the fishing line winding surface, and the convex portions between these twill grooves are closely spaced in the axial and circumferential directions. Therefore, if the fishing line rides on a certain convex part, it will ride on the adjacent convex part along the winding angle and will not slip between the convex parts. There isn't. Therefore, it is not possible to engage the side surface of the convex portion to stop the axial slippage, and furthermore, the fishing line comes into contact only with the top surface of the convex portion between the twill grooves, so that the fishing line of the fishing line cannot be stopped. Conversely, the contact area with the winding surface also decreases.
As a result, according to the conventional example, if the winding angle of the fishing line deviates from the angle of inclination of the streak, the wound fishing line will slide toward the downward side (smaller diameter side) in the direction of inclination of the fishing line winding surface. . This slipping of the fishing line toward the smaller diameter side causes the fishing line winding part to become slack, so if the fishing line is wound over this slack part, when casting, the outside part of the fishing line will be pulled from the slack part. There is a problem of them bunching up and pulling out from the spool.

The purpose of the present invention is to prevent slipping of the fishing line no matter what direction the fishing line is wound on the fishing line winding surface, and even if the fishing line wound on the fishing line winding surface rides on the protrusion. The purpose of this invention is to prevent the fishing line from becoming loose due to this slippage.

(Means for Solving the Problems) Therefore, the present invention provides a winding drum 1 in which the fishing line winding surface 11 on the outer periphery is inclined with respect to the axis, and a pair of flanges 2 and 3 provided at both ends of the winding drum 1. A spool consisting of a plurality of minute protrusions 5 arranged at predetermined intervals in the axial direction between both ends of the winding surface 11 to prevent the fishing line from sliding in the axial direction; At least one minute protrusion 5a that prevents the fishing line from sliding in the axial direction is provided protrudingly on the arc line toward which the fishing line is directed, and each of these minute protrusions 5, 5a is shaped to allow the fishing line to slide down toward the proximal end of the protrusion. , each of the minute protrusions 5 and each of the minute protrusions 5a are arranged at intervals that allow the fishing line to slip down.

(Function) When the fishing line is wound around the winding surface 11, no matter what direction the fishing line is wound around the winding surface 11, 1
~A second ply of fishing line is engaged with the side surface of minute protrusions 5 provided at predetermined intervals in the axial direction, or with the side surfaces of minute protrusions 5a provided on arcuate lines extending in the circumferential direction of each of these minute protrusions 5. In addition, each of the minute protrusions 5, 5a is
It is formed in a shape that allows the fishing line to slide down toward the base end of the protrusion, and each of the minute protrusions 5 and each minute protrusion 5a are arranged at intervals that allow the fishing line to slip down. Therefore, even if the fishing line wound on the fishing line winding surface 11 rides on the minute protrusion 5, it will not slide off the minute protrusion 5 without being hindered by the minute protrusion 5a provided in the circumferential direction with respect to the minute protrusion 5. In addition, the fishing line that has slipped off the minute protrusion 5 is pushed downward in the inclined direction of the fishing line winding surface 11 by the minute protrusion 5 or the minute protrusion 5a provided circumferentially relative to the minute protrusion 5. It can stop slipping.

(Example) The spool shown in the drawing has a fishing line winding surface 1 on the outer periphery.
1, and a pair of flanges 2 and 3 provided at both ends of the winding drum 1.
is inclined with respect to the axis. Moreover, the winding drum 1
A mounting plate 4 having a fitting hole 41 for fitting the spool shaft is provided at one end of the spool.

However, in the embodiment shown in FIGS. 1 and 2, a plurality of minute protrusions 5 are provided between both ends of the winding surface 11 at predetermined intervals in the axial direction to prevent the fishing line from sliding in the axial direction. At least one minute protrusion 5a that prevents the fishing line from slipping in the axial direction is protrudingly provided on an arc line extending in the circumferential direction of each minute protrusion 5, and each of these minute protrusions 5, 5a is attached to the base end of the protrusion of the fishing line. In addition to having a shape that allows the fishing line to slip down, each of the minute protrusions 5 and each of the minute protrusions 5a are arranged at intervals that allow the fishing line to slip down.

These minute protrusions 5, 5a are provided at approximately the same height as the thickness of the fishing line L wound on the winding surface 11, and at intervals wider than the thickness of the fishing line L.

Moreover, these minute protrusions 5, 5a are formed in such a structure that the fishing line does not ride on the fishing line regardless of the winding direction of the fishing line L, or that even if it rides on the fishing line, it slips down and can be locked. For example, it may be formed into a bowl shape as shown in FIG. 3, or approximately V-shaped as shown in FIG.

In addition, in the case shown in FIGS. 1 and 2, the minute protrusions 5 and 5a are arranged in series in the axial direction with a phase difference of 180 degrees, but in other cases, as shown in FIG. They may be arranged in rows while being displaced in the circumferential direction, they may be provided in a staggered manner in the axial direction, or they may be provided at random. is not particularly limited.

Therefore, the fishing line L is wound onto the fishing line winding surface 11 by rotating a rotating frame (not shown) having a bail arm. It is wrapped in

When the fishing line is wound, the first and second plies of the fishing line are not wound by the minute projections 5 or 5a regardless of the winding direction.
The fishing line winding surface 11 is engaged with the side surface of the fishing line winding surface 11 and slides in the axial direction.
In addition, even if the fishing line being wound on the fishing line winding surface 11 rides up on the minute protrusions 5,
The minute protrusions 5a are provided in the circumferential direction of the minute protrusions 5.
The fishing line slides off the minute projections 5 without being hindered by the projections, and the fishing line that has slipped off the minute projections 5 can be stopped from sliding downward in the inclination direction of the fishing line winding surface 11 by the minute projections 5 or by the minute projections 5a provided circumferentially relative to the minute projections 5. Therefore, the first and second plies of fishing line can be wound without slack.

Further, in the embodiment shown in FIGS. 6 and 7, the minute protrusions and annular anti-slip grooves 6 are provided on the winding surface 11, and the anti-slip grooves 6 are arranged at predetermined intervals in the axial direction. There are many rows with .

In this case, the minute protrusions can stop the fishing line from slipping, and the edges of the anti-skid groove 6 can increase the slipping resistance of the fishing line, making it difficult for the fishing line to slip on the portions of the line that do not engage with the minute protrusions. Therefore, the fishing line can be wound more orderly.

The anti-slip groove 6 has a higher anti-slip effect as the angle of inclination of the winding surface 11 is smaller.

Further, the anti-slip groove 6 may be formed in an annular shape, or may be spiral or twilled, and its shape is not particularly limited.

(Effect of the invention) As described above, the present invention has a plurality of minute protrusions arranged at a predetermined interval in the axial direction between both ends of the fishing line winding surface 11 that is inclined with respect to the axis to prevent the fishing line from slipping in the axial direction. 5 and at least one minute protrusion 5a that stops the fishing line from sliding in the axial direction on the arc line extending in the circumferential direction of each of these minute protrusions 5. Since minute protrusions protruding outward from the winding surface 11 are provided at axial and circumferential positions, the fishing line can be prevented from slipping no matter what direction it is wound around the winding surface 11. Each minute protrusion 5, 5a is formed in a shape that allows the fishing line to slide down toward the base end of the protrusion, and
Since the minute protrusions 5 and the minute protrusions 5a are arranged at intervals that allow the fishing line to slip down, the fishing line wound on the fishing line winding surface 11 rides on the minute protrusions 5. Also, the fishing line that has slipped from the minute protrusion 5 will slide down from the minute protrusion 5 without being obstructed by the minute protrusion 5 a provided in the circumferential direction of the minute protrusion 5 . Alternatively, the minute protrusions 5a provided in the circumferential direction of the minute protrusions 5 can prevent the fishing line winding surface 11 from sliding in the downward direction of the inclination direction. Therefore, it is possible to prevent the fishing line from loosening due to slipping.
This allows for orderly wrapping.
