Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a roller clutch used as a fishing gear reel clutch.

[0002]

2. Description of the Related Art In a fishing reel, for example, an outer ring side is fixed to a fishing rod, a fishing line is wound and held on an inner ring side, and a handle shaft is provided on the inner ring. When the fishing line is pulled, the inner ring is locked to the outer ring. So that the fishing line is no longer pulled out, and when winding the fishing line, the lock between the inner ring and the outer ring is released so that the fishing line can be wound up.
A one-way clutch is employed. In the fishing tackle reel, among the one-way clutches, a roller clutch is used in order to make the mechanism simple and compact.

A roller clutch defines an enlarged space between opposing peripheral surfaces of an outer ring and an inner ring, accommodates a roller in the enlarged space, and rotates the inner ring relative to the outer ring in one direction. When the roller bites into the wedge-shaped portion of the enlarged space, the outer ring and the inner ring are integrally engaged, and when the inner ring is rotated relative to the outer ring to the other, the roller comes off from the wedge-shaped portion of the enlarged space, The engagement between the outer ring and the inner ring is released.

[0004]

By the way, in such a roller clutch, enlarged spaces are formed at a plurality of positions at equal intervals, and rollers are arranged in these enlarged spaces. Each of these rollers is urged by an elastic body such as a leaf spring in a direction to bite into the wedge-shaped portion of the enlarged space. As described above, in the roller clutch, the elastic body is provided for each roller. Therefore, the number of parts increases, the number of assembling steps increases, the parts management and assembling work become complicated, and the manufacturing cost increases. I was following.

Further, in a fishing gear reel clutch, a needle,
When throwing a device such as a weight into water such as a river or the sea, it is necessary to release the locked state so that the fishing line can be fed out freely. In order to release the lock, the rollers must be moved against the urging force of the elastic body to maintain the state in which the rollers are detached from the wedge-shaped portion of the enlarged space. Since the elastic body is provided, it is necessary to move each of those rollers. Therefore, the structure of the clutch for fishing tackle reels is complicated, and the cost is further increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fishing reel clutch which has a small number of parts, has a simple mechanism, can reduce the number of assembling steps, and is inexpensive.

[0007]

A clutch for a fishing tackle reel according to the present invention defines an enlarged space between opposing peripheral surfaces of an outer ring and an inner ring, accommodates a roller in the enlarged space, and attaches a roller to the outer ring. On the other hand, when the inner ring is relatively rotated to one side,
When the roller bites into the wedge-shaped portion of the enlarged space, the outer ring and the inner ring are integrally engaged, and when the inner ring is relatively rotated with respect to the outer ring to the other side, the roller is enlarged. In the fishing tackle reel clutch which is disengaged from the wedge-shaped portion of the space and the engaged state of the outer race and the inner race is released, the roller is moved to the radial position by a retainer interposed between the outer race and the inner race. While holding,
By urging the retainer in the circumferential direction by an elastic body, the roller is urged in a direction in which the roller bites into the wedge-shaped portion, and by operating a retainer moving means, the retainer is biased by the elastic body. It is made to move in the circumferential direction in opposition.

According to the fishing gear reel clutch of the present invention, each roller is urged by the elastic body via the retainer. That is, according to the fishing gear reel clutch,
Since only the retainer needs to be urged, only one elastic body is required. Further, according to the fishing tackle reel clutch of the present invention, even when the lock is forcibly released, the rollers can be moved simultaneously by moving the retainer against the urging force of the elastic body. No special structure is required.

[0009]

FIG. 1 is a conceptual diagram showing a first embodiment of a fishing tackle reel clutch according to the present invention. The clutch 10 has an outer race 11 and an inner race 12 arranged concentrically, and an annular retainer 13 is loosely fitted between them.

In the clutch 10, concave portions 14 are formed at a plurality of locations (eight locations in FIG. 1) at equal intervals on the inner peripheral surface of the outer race 11. The counterclockwise ends of these recesses 14 have a wedge-shaped surface 14a formed substantially following a tangent to the inner peripheral surface of the outer race 11, as shown in an enlarged view in FIG. The portion is formed in an arc shape and forms an edge 14b with the inner peripheral surface of the outer ring 11 and associates with each other.

The inner ring 12 has a shaft 15 at the center thereof,
A handle (not shown) is provided at an end of the 15. The retainer 13 retains the rollers 16 and has a number of holes 17 corresponding to the number of the concave portions 14 (eight in FIG. 1) at equal intervals. Side walls 18, 19 of retainer 13, which define these holes 17,
Surfaces 18a and 19a from the middle to the inner peripheral side have the same or slightly larger radius of curvature as the outer radius of the roller and are formed in a direction to narrow the hole 17. The roller 16 is accommodated in the hole 17 of the retainer 13, and is defined by the concave portion 14 of the outer ring 11 and the outer peripheral surface of the inner ring 12 between the inner peripheral surface of the outer ring 11 and the outer peripheral surface of the inner ring 12. Is disposed in the enlarged space 20.

In the clutch 10, one end of a lever 21 is fixedly or integrally formed on a part of the retainer 13, and the lever 21 extends toward the outer ring 11. And the lever
21 is linked to the outer ring via a spring 22
22 urges the retainer 13 in a counterclockwise direction. Therefore, in this clutch 10, as shown in FIG. 2, the roller 16 is pressed against the side wall 19 of the retainer 13 and pressed against the wedge-shaped surface 14a of the concave portion 14 without load.

The outer ring 11 of the clutch 10 is fixed to a fishing rod or the like, and a fishing line is wound around a shaft 15 of the inner ring 12 or the like. When a hook such as a hook or a weight is thrown into water such as a river or sea, the lever 21 is moved against the urging force of the spring 22 so that the retainer 13 moves with the lever 21 as shown in FIG. The roller 16 is moved clockwise as shown, thereby moving the roller 16 away from the wedge-shaped surface 14a of the recess 14. Therefore, the inner race 12 is free from the outer race 11, and the fishing line is paid out according to the momentum of the thrown weight.

When the device is put into the predetermined position, the lever 21 is returned to the original state. When the fish is hooked on the needle, the fish is pulled by the fish and a force in the feeding direction acts on the fishing line. However, as shown in FIG. 2, the roller 16 comes into contact with the wedge-shaped surface 14 a of the concave portion 14 and the wedge-shaped surface 14 a The fishing line does not bite into the outer peripheral surface of the inner ring 12 and is not pulled out. When catching a fish, the handle is rotated to rotate the inner ring 12 clockwise to wind up the fishing line. However, as shown in FIG. 4, a force acts on the roll 16 in a direction away from the wedge-shaped surface 14a. Therefore, the locked state is released, and the fishing line can be wound up.

FIG. 5 is a conceptual diagram showing a second embodiment of a fishing gear reel clutch according to the present invention. The clutch 50 according to the second embodiment has a bracket 23 disposed on the outer race 11 and a tension adjuster for changing the tension of the spring 22 to the bracket 23.
24, and the spring 22 is connected to the outer ring via the tension adjuster 24.
Since it is connected to 11, the set load of the spring 22 can be arbitrarily changed.

The tension adjuster 24 includes a bolt 25
Into the hole of the bolt 25 to lock the spring 22
A lock nut 27 is provided to lock the bolt 25 in a predetermined position. In the second embodiment, the tension adjuster 24 is installed on the outer race 11, but the point is that the tension adjuster 24 may be interposed between the end of the spring 22 and a member that locks the spring 22. The mounting position may be appropriately selected.

FIG. 6 is a conceptual diagram showing a third embodiment of the present invention. In the clutch 60 according to the third embodiment, the inner ring 12 is fixed, and a concave portion 14 is formed on the outer peripheral surface of the inner ring 12.
The spring 22 for urging the retainer 13 includes the lever 21 and the inner ring 12.
And the like on the fixed side.

A clutch according to a fourth embodiment shown in FIG.
70 indicates that the lever 21 and the spring 22 have the outer ring 11 and the inner ring
A lever 21 and a spring 22 are housed in a cutout provided in the outer ring 11 so as not to protrude from the end face of the contour of 12. According to such a clutch, the size can be further reduced.

Further, in the first embodiment, the spring 22 is interposed between the lever 21 and the outer ring 11, but the point is that the cage is
It is sufficient that the roller 13 is always urged in the direction in which the roller 16 comes into contact with the wedge-shaped surface 14a of the recess 14. Good. Further, in the first embodiment, the coil spring 22 is used as the elastic body. However, the present invention is not limited to the coil spring 22, and an elastic body such as a leaf spring or rubber can be used.

For example, in the clutch 80 of the fourth embodiment shown in FIG. 8, the rim portion 44 of the retainer 43 is formed in a substantially disk shape, and the cylindrical portion 45 rising from the inner peripheral edge of the rim portion 44.
A total of four convex portions 46 are provided at the outer peripheral surface radiation position of
A substantially pentagonal spring member 47 fixed to the outer race 11 urges the retainer 43 in a counterclockwise direction in FIG.

In this clutch 40, a spring member
47 also functions as an inner snap ring for preventing the retainer 43 from coming off. Further, the spring member 47 does not need to be bent into a substantially pentagonal shape, and a linear spring member may be provided at a position corresponding to each of the protrusions 46.

Further, the clutch 90 of the fifth embodiment shown in FIG. 9 includes a retainer 13 and a handle 91 fixed at a predetermined position.
Are connected via a connecting member 92 such as a wire, a thread, a rod, and the like, and the handle 91 is rotated about a fulcrum 93 to perform locking and unlocking.

In the first embodiment, the lever 21 is disposed on the retainer 13, and one end of the spring 22 is locked on the lever 21. That is, in the above-described embodiment, the retainer 13 is linked to the spring 22 via the lever 21, but the lever 21 is independently disposed on the retainer 13, and the spring 22 is disposed on the retainer 13. It may be locked by a spring hook or the like.

In the first embodiment, when the lever 21 is operated against the urging force of the spring 22, the retainer 13
The roller 16 is pressed against the edge 14b of the concave portion 14 and the outer peripheral surface of the inner ring 12 through the roller. In this case, if the lever 21 is pulled strongly, the magnitude of the pressure contact force increases, and a frictional resistance corresponding to the force is generated in the inner ring 12. In this way, for example, when the fishing line is paid out, an appropriate frictional resistance can be given to the fishing line. However, when the inner ring 12 is to be completely opened irrespective of the operating force of the lever 21, a stopper 28 is provided in association with the lever 21 as shown by a broken line in FIG. The roller 16 may be stopped slightly short of the edge 14b of the concave portion 14 in the state of contact with the roller 28. Also, this stopper 28
Of course, it can be installed not only in 11 but also in other appropriate places.
