Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a spool for a fishing reel, and more particularly, to a spool that is inserted into and supported by a spool shaft and is used to wind fishing line around a winding drum.

(Prior art) Generally, this type of spool has a winding drum with a circular cross section,
It consists of a pair of flanges extending radially outward from both ends of the winding drum, and a shaft hole is provided in the center of the winding drum to fit into the spool shaft and suppress radial movement with respect to the spool shaft. ing.

By the way, since the outer diameter of the winding drum is significantly larger than the inner diameter of the shaft hole provided corresponding to the spool shaft, the wall thickness of the winding drum becomes large, and as a result, it becomes heavy and During molding, sink marks and cavities are likely to occur.

Conventionally, as described in Japanese Utility Model Application Publication No. 58-152874, an axially central portion of the body portion is provided with a predetermined width at an intermediate portion between the outer circumferential surface of the winding drum and the shaft hole. A plurality of holes opening from the central part in the axial direction to both ends are provided at regular intervals in the circumferential direction, and between each of these holes, a plurality of holes with the insertion hole as the center are provided. A spool has been proposed in which pillar-shaped ribs are formed in the radial direction and centered around each ray and parallel to the ray.

(Problems to be Solved by the Invention) However, according to this conventional spool, the fishing line is wound onto the winding body when a large tension is applied to the fishing line, such as when catching a big fish. Then, due to the winding force corresponding to this winding force, the diameter of the outer circumferential portion of the winding drum, that is, the outer circumferential portion between the outer circumferential surface and the hollow hole is reduced slightly,
The tightening force acts directly from each rib to the inner peripheral portion of the winding drum, that is, around the shaft hole, and the distance between the shaft hole and the outer peripheral surface of the spool shaft is Since the spool is made small so that there is no wobbling, even a slight reduction in the diameter of the winding drum causes the shaft hole to deform, and this shaft hole is pressed against the outer peripheral surface of the spool shaft, and the spool This locks the spool, making it impossible to remove the spool with the fishing line wrapped around it. For this reason, it is difficult to remove the spool to fix unraveled fishing line, or to remove the spool with fishing line already wound on it and replace it with another spool wrapped with a different size of fishing line. , it was a bad idea to overuse it.

The present invention was devised in view of the above points, and the purpose is to prevent the shaft hole from deforming due to the tightening force even if the winding drum contracts in diameter due to the tightening force acting on the winding drum, and to prevent the spool from deforming due to the tightening force. This prevents the device from being locked.

(Means for Solving the Problems) Accordingly, the present invention provides a synthetic resin fitting tube 1 having a shaft hole 11 that is inserted into the spool shaft of a fishing reel and suppresses movement in the radial direction with respect to the spool shaft. A plurality of ribs 2 extending axially over almost the entire length of the shaft hole 11 are provided at predetermined intervals in the circumferential direction on the outer periphery of the shaft hole 11. A synthetic resin spool body 3 having a shape is integrally formed, and each of the ribs 2 is
The fitting tube 1 is inclined in the circumferential direction from the outer circumferential surface toward the inner circumferential surface of the winding drum 31, so that it can be elastically deformed by the winding force when winding the fishing line onto the winding drum 31.

(Function) Fitting tube 1 with shaft hole 11 and spool body 3
Since the winding drum 31 is connected by a plurality of ribs 2 that are inclined in the circumferential direction and are elastically deformed by the winding force, the winding drum 31 is elastically deformed by the winding force acting on the winding drum 31. Even if the winding drum 31 is deformed and its diameter is reduced, the rib 2 is elastically deformed by the diameter reduction of the winding drum 31, and the diameter reduction of the fitting tube 1 can be absorbed. Therefore, the shaft hole 11 of the fitting cylinder 1 can be prevented from being deformed by the seaming force, and as a result, the shaft hole 11 is pressed against the outer circumferential surface of the spool shaft and the spool is locked. This allows the spool to be easily removed from the spool shaft with the fishing line wound around the winding drum 31. In this way, the spool can be easily removed with the fishing line wound around the winding drum 31, so it can be used when removing the spool to fix unraveled fishing line, or when using other fishing lines wound with different sizes of fishing line. Work such as replacing the spool can be done easily and quickly, and it is easy to use.

Moreover, when the rib 2 elastically deforms to absorb the diameter reduction of the fitting cylinder 1 while preventing the spool from locking as described above, the amount of diameter reduction due to the winding force of the winding drum 31 is very small. Since the diameter of the winding drum 31 is reduced slightly, the winding layer of the fishing line wound around the winding drum 31 becomes loose, and the fishing line wound later is loosened between the fishing lines in the winding layer. Even if a phenomenon in which the fishing line bites in occurs, since the amount of diameter reduction of the winding drum 31 is extremely small, the amount in which the fishing line bites in is also small.

Therefore, even if the throwing distance is somewhat affected by the phenomenon of fishing line digging in, troubles such as not being able to cast or breaking the line will not occur.

(Example) The illustrated spool is a spool that is removably attached to the spool shaft of a spinning reel, and has a shaft hole 11 that is inserted into the spool shaft to suppress radial movement with respect to the spool shaft. The shaft hole 11 is provided on the outer periphery of the synthetic resin fitting tube 1.
A plurality of ribs 2 are provided at predetermined intervals in the circumferential direction, extending in the axial direction over almost the entire length of the winding drum 31 and a pair of flanges 32, 3.
3 is integrally formed with a synthetic resin spool main body 3 by molding, and each of the ribs 2 is inclined in the circumferential direction from the outer circumferential surface of the fitting tube 1 toward the inner circumferential surface of the winding drum 31, This allows the fishing line to be elastically deformed by the winding force when winding the fishing line onto the winding drum 31.

Also, in the drawing, eight ribs 2 with a wall thickness of 1.5 mm are provided,
Each of these ribs 2 is inclined at 30 degrees to the rear side in the winding direction of the fishing line with respect to the radial direction line X. Note that the angle of inclination and the direction of inclination are not particularly limited.

Further, one end of the fitting tube 1 and one end of the winding drum 31 are connected by a disk portion 4. Note that this circular portion 4 is not necessarily necessary.

In the figure, reference numeral 5 indicates a cross-shaped anti-rotation groove provided on the edge of the fitting cylinder 1, and reference numeral 6 indicates a screw hole continuous to one end of the shaft hole 11.

In the spool constructed as described above, the shaft hole 11 is inserted into the spool shaft 70 of the spinning reel as shown in FIG.
1 to prevent rotation of the spool with respect to the spool shaft 70, while the threaded hole 6 of the spool
A holding cylinder 73 having an operating body 72 and an engaging body 75 having an engaging protrusion 75a that engages with a locking groove 74 provided at the shaft end of the spool shaft 70 are attached to the spool shaft 70. 75a is engaged with the locking groove 74 to prevent the spool from moving in the axial direction with respect to the spool shaft 70. Then, by rotating the handle, the rotating frame 76 with the bail arm is rotated.
is driven to wind the fishing line onto the winding drum 31 of the spool.

Therefore, when catching a big fish, the fishing line is wound onto the winding drum 31 with a large tension acting on the fishing line, and a winding force corresponding to this winding force is applied to the winding drum 31. is elastically deformed, and the winding drum 3
1 is reduced in diameter very slightly, the rib 2 is elastically deformed and bent with respect to the fitting tube 1 due to the diameter reduction of the winding drum 31, and due to the deflection of the rib 2, the fitting tube 1 is This allows it to absorb diameter reduction. Therefore, the shaft hole 11 of the fitting cylinder 1 can be prevented from being deformed by the seaming force, and as a result,
This prevents the spool from being locked due to the shaft hole 11 coming into pressure contact with the outer peripheral surface of the spool shaft, and the spool can be easily removed from the spool shaft with the fishing line wound around the winding drum 31. It is. In this way, the spool can be easily removed with the fishing line wound around the winding drum 31, so it can be used when removing the spool to fix unraveled fishing line, or when using other fishing lines wound with different sizes of fishing line. Work such as replacing the spool can be done easily and quickly, and it is easy to use. The spool can be removed by pushing the operating body 72 and expanding the engaging protrusion 75a side portion of the engaging body 75 radially outward to open the locking groove 74 of the engaging protrusion 75a.
It disengages from the engagement.

Further, when the rib 2 elastically deforms to absorb the diameter reduction of the fitting tube 1 while preventing the spool from locking as described above, the amount of diameter reduction due to the winding force of the winding drum 31 is very small. Since it is small, winding drum 3
Due to the diameter reduction in step 1, the winding layer of the fishing line wound around the winding drum 31 becomes loose, and a phenomenon in which the fishing line wound later gets wedged between the ends of the fishing line in the winding layer occurs. In the first place, since the amount of diameter reduction of the winding drum 31 is very small, the amount of fishing line biting is also small.

Therefore, even if the throwing distance is slightly affected by the phenomenon of the fishing line digging into the fishing line, problems such as not being able to cast or the line breaking will not occur.

In addition to being used for spinning reels, the spool of the present invention may also be used for fishing reels such as double-bearing reels.

(Effects of the Invention) As described above, the present invention provides a plurality of fitting tubes 1 having a shaft hole 11 and a winding drum 31 of a spool body 3 that are inclined in the circumferential direction and that are elastically deformed by the winding force. rib 2
Even if the winding drum 31 is elastically deformed due to the winding force acting on the winding drum 31 and the winding drum 31 contracts in diameter, the diameter reduction of the winding drum 31 causes the ribs 2 to by elastically deforming the fitting cylinder 1.
It is possible to absorb the shrinkage of the diameter. Therefore, the shaft hole 11 of the fitting tube 1 can be prevented from being deformed by the seaming force, and as a result, the shaft hole 11
This prevents the spool from being locked due to pressure contact with the outer peripheral surface of the spool shaft, and the spool can be easily removed from the spool shaft with the fishing line wound around the winding drum 31. . In this way, the spool can be easily removed with the fishing line wound around the winding drum 31, so it can be used when removing the spool to fix unraveled fishing line, or when using other fishing lines wound with different sizes of fishing line. Work such as replacing the spool can be done easily and quickly, and it is easy to use.

Moreover, when the rib 2 elastically deforms to absorb the diameter reduction of the fitting cylinder 1 while preventing the spool from locking as described above, the amount of diameter reduction due to the winding force of the winding drum 31 is very small. Since the diameter of the winding drum 31 is reduced slightly, the winding layer of the fishing line wound around the winding drum 31 becomes loose, and the fishing line wound later is loosened between the fishing lines in the winding layer. Even if the fishing line bites in, the amount of diameter reduction of the winding drum 31 is very small in the first place, so the amount of fishing line biting in is also small.

Therefore, even if the fishing line bite affects the casting distance to some extent, problems such as being unable to cast or breaking the line will not occur.
