Description

Technical Field

[0001] This invention relates to a double-bearing winding reel. Background Technology

[0002] Conventionally, dual-bearing winding reels equipped with a roller clutch and a rolling bearing are known. The roller clutch prevents rotation of the handle shaft in one direction, while the rolling bearing rotatably supports the handle shaft (see Patent Document 1). To suppress the rolling effect of the roller clutch on the load from the handle shaft, the rolling bearing is arranged adjacent to the roller clutch in the axial direction of the handle shaft.

[0003] Patent document 1: Japanese Patent Application Publication No. 8-214741.

[0004] Patent document 2: Japanese Patent Application Publication No. 9-47195.

[0005] In the dual-bearing reel disclosed in Patent Document 1, the rolling bearing is arranged adjacent to the roller clutch in the axial direction of the handle shaft. That is, the rolling bearing and the roller clutch are arranged side by side in the axial direction relative to the reel body. Therefore, the space for axially arranging the rolling bearing and the roller clutch increases, making it possible to increase the size of the reel body in the axial direction. If the reel body is increased in the axial direction, the handle position is moved away from the fishing rod, which can easily impair the winding operability and efficiency.

[0006] Therefore, Patent Document 2 discloses a double-bearing winding wheel in which a roller clutch is arranged between the left and right side plates of the winding wheel body to suppress the axial enlargement of the winding wheel body. However, in the double-bearing winding wheel of Patent Document 2, the handle shaft is enlarged axially. Summary of the Invention

[0007] The purpose of this invention is to suppress the enlargement of the handle shaft in the axial direction, thereby achieving miniaturization of the winding wheel body.

[0008] One embodiment of the present invention provides a double-bearing winding reel comprising a winding reel body, a handle shaft, a handle, a first bearing, and a roller clutch. The handle shaft is rotatably mounted on the winding reel body. The handle shaft has a first end and a second end opposite to the first end. The handle is connected to the first end of the handle shaft. The first bearing rotatably supports the second end of the handle shaft. The roller clutch is configured to overlap with the first bearing axially on the handle shaft when viewed radially from the handle shaft, thereby preventing rotation of the handle shaft in one direction.

[0009] In this dual-bearing winding reel, when viewed radially from the handle shaft, the roller clutch is configured to overlap with the first bearing in the axial direction of the handle shaft. Therefore, the size of the handle shaft is suppressed in the axial direction, and the size of the winding reel body can be minimized. In addition, axial space is easily ensured, making it easy to install additional functions such as a speed-changing mechanism on the handle shaft.

[0010] Alternatively, the handle shaft may also have a recess located at the second end, opening in a first direction from the first end toward the second end. Alternatively, the first bearing may be disposed within the recess of the handle shaft. Alternatively, a roller clutch may be disposed on the outer periphery of the second end of the handle shaft. In this case, a roller clutch with a larger diameter can be used compared to the case where the roller clutch is disposed within the recess of the handle shaft, thus increasing the permissible torque.

[0011] Alternatively, the winding reel body may also have a support shaft disposed within a recess on the handle shaft to support the first bearing. In this case, the first bearing can be supported with a simple structure.

[0012] Alternatively, the double-bearing reel may also include a cylindrical component and a second bearing. The cylindrical component is integrally rotatably mounted to the handle shaft between the first and second ends, and the second bearing rotatably supports the handle shaft via the cylindrical component. Alternatively, the reel body may have a frame including a support shaft and a cover covering one side of the frame. Alternatively, the second bearing may be disposed within the cover. Alternatively, the cylindrical component may have a protrusion that projects radially from the outer periphery of the cylindrical component towards the handle shaft, restricting the movement of the second bearing in a first direction. In this case, the movement of the second bearing in the first direction can be restricted with a simple structure. Furthermore, compared to fixing the second bearing to the cover with bolts, the number of parts can be reduced.

[0013] Alternatively, the outer diameter of the second end of the handle shaft can be larger than the outer diameter of the first end. In this case, a roller clutch with a high allowable torque can be used.

[0014] Invention Effects According to the present invention, it is possible to suppress the enlargement of the handle shaft in the axial direction and to achieve miniaturization of the winding wheel body. Attached Figure Description

[0018] One embodiment of the present invention provides a dual-bearing reel 100 that is an electric reel capable of releasing fishing line forward. The dual-bearing reel 100, as described... Figure 1 and Figure 2 As shown, it includes a winding wheel body 2, a drum 3, a motor 4, a handle shaft 5, a handle 6, a first bearing 20, and a roller clutch 30.

[0019] In the following description, the direction in which the fishing line is released during fishing is referred to as "front," and the opposite direction is referred to as "rear." Left and right refer to the left and right sides when viewed from behind the double-bearing reel 100. The direction in which the handle shaft 5 extends is referred to as the axial direction, and the direction perpendicular to the axial direction is referred to as the radial direction. In this embodiment, the axial direction is consistent with the left and right direction.

[0020] The winding wheel body 2 has a frame 7, a first side cover 8, a second side cover 9, and a support shaft 10.

[0021] Inside the winding reel body 2, there are reciprocating movement mechanisms that work in conjunction with the drum 3, rotation transmission mechanisms that transmit the rotation of the motor 4 and handle shaft 5 to the drum 3, clutch mechanisms that transmit and cut off the rotational force of the handle 6 relative to the drum 3, and clutch control mechanisms that control the clutch mechanisms.

[0022] Frame 7 has a first side plate 11, a second side plate 12, a mechanism mounting plate 13, multiple connecting parts (not shown), and a rod mounting part 14. The first side plate 11 is located on the right side of frame 7. The second side plate 12 is disposed away from the first side plate 11 in the left-right direction. The second side plate 12 is located on the left side of frame 7.

[0023] Mechanism assembly plate 13, such as Figure 2 As shown, it is disposed between the first side plate 11 and the first side cover 8. The mechanism mounting plate 13 is fixed to the right side of the first side plate 11. The mechanism mounting plate 13 assembles various mechanisms disposed inside the winding wheel body 2. The mechanism mounting plate 13 has a support portion 13a. The support portion 13a is a cylindrical recess that extends axially. The support portion 13a opens to the right. The support portion 13a supports the roller clutch 30.

[0024] Multiple connecting parts extend in the left-right direction, connecting the first side plate 11 and the second side plate 12. The rod mounting part 14 is the part for mounting the fishing rod, and extends in the front-back direction at approximately the middle position of the first side plate 11 and the second side plate 12.

[0025] The first side cover 8 is an example of a cover. The first side cover 8 covers the right side of the frame 7. The first side cover 8 has a boss portion 8a that extends through the axial direction. The boss portion 8a is formed in a cylindrical shape. The second side cover 9 covers the left side of the frame 7.

[0026] The support shaft 10 extends axially and supports the first bearing 20. The support shaft 10 is formed in the mechanism assembly plate 13 of the frame 7. The support shaft 10 is disposed on the inner circumferential side of the support portion 13a of the mechanism assembly plate 13. The support shaft 10 extends to the right from the bottom center of the support portion 13a.

[0027] A counter box 16, fixed to the first side plate 11 and the second side plate 12, is provided on the upper part of the winding reel body 2. The counter box 16 includes a water depth display 17, an operation switch 18 for setting various parameters of the double-bearing winding reel 100, and a push-operation unit 19 for adjusting the output of the motor 4. Furthermore, inside the counter box 16, a control unit (not shown) for various controls of the double-bearing winding reel 100 is housed.

[0028] The spool 3 is the component that winds the fishing line around its outer periphery and is rotatably supported on the reel body 2 between the first side plate 11 and the second side plate 12.

[0029] Motor 4 is located inside the winding reel body 2. Motor 4 is configured to be PWM controlled by the control unit and rotate together with the drum 3 in the winding direction in accordance with the pushing operation of the pushing operation unit 19.

[0030] The handle shaft 5 is rotatably mounted on the winding reel body 2. The handle shaft 5 is rotatably supported on the winding reel body 2 via a first bearing 20 and a second bearing 50 (described later). The handle shaft 5 is positioned on the right side of the frame 7. The handle shaft 5 extends axially, passing through the boss portion 8a of the first side cover 8. A drive gear and a traction mechanism are arranged axially around the handle shaft 5.

[0031] The handle shaft 5 has a first end 5a, a second end 5b, and a recess 5c. In this embodiment, the first end 5a is the right end of the handle shaft 5. The second end 5b is the opposite side to the first end 5a and is the left end of the handle shaft 5. The outer diameter of the second end 5b is larger than the outer diameter of the first end 5a. The recess 5c is provided in the second end 5b. The recess 5c is a cylindrical recess that extends axially. The recess 5c opens in a first direction from the first end 5a toward the second end 5b. In this embodiment, the first direction coincides with the leftward direction. The support shaft 10 is disposed within the recess 5c.

[0032] The handle 6 is connected to the first end 5a of the handle shaft 5. The handle 6 is integrally and rotatably fixed to the handle shaft 5. The handle 6 has a handle arm 6a and a gripping part 6b. The handle arm 6a extends radially. One end of the handle arm 6a is fixed to the first end 5a of the handle shaft 5. The gripping part 6b is fitted to the other end of the handle arm 6a.

[0033] The first bearing 20 is disposed within the recess 5c of the handle shaft 5, rotatably supporting the second end 5b of the handle shaft 5. The first bearing 20 is supported on the support shaft 10. The first bearing 20 is mounted on the outer peripheral surface of the support shaft 10. In this embodiment, the first bearing 20 is composed of rolling bearings 20a and 20b. The rolling bearings 20a and 20b are arranged adjacent to each other in the axial direction.

[0034] A roller clutch 30 is disposed on the outer periphery of the second end 5b of the handle shaft 5, preventing rotation of the handle shaft 5 in one direction. The roller clutch 30 prevents rotation of the handle shaft 5 in the direction opposite to the winding direction. The roller clutch 30 is mounted on the support portion 13a of the mechanism mounting plate 13. When viewed radially, the roller clutch 30 overlaps axially with the first bearing 20.

[0035] The roller clutch 30 has an outer ring 30a and a plurality of rolling elements 30b. The outer ring 30a is non-rotatably mounted to a support portion 13a of the mechanism mounting plate 13. The outer ring 30a has a cam surface (not shown) on its inner circumferential surface. The plurality of rolling elements 30b are cylindrical and are disposed between the inner circumferential surface of the outer ring 30a and the outer circumferential surface of the second end 5b of the handle shaft 5. The plurality of rolling elements 30b allow rotation in the winding direction of the handle shaft 5. Alternatively, the roller clutch 30 may have an inner ring fixed to the outer circumferential surface of the second end 5b of the handle shaft 5.

[0036] The roller clutch 30 is prevented from disengaging from the support portion 13a of the mechanism mounting plate 13 by means of a push plate 32 fixed to the mechanism mounting plate 13. At least a portion of the push plate 32 overlaps axially with the second end portion 5b. Here, the handle shaft 5 has a small diameter portion 5d whose outer diameter is smaller than that of the second end portion 5b. The small diameter portion 5d is disposed adjacent to the second end portion 5b. A portion of the push plate 32 is configured to radially surround at least a portion of the outer peripheral surface of the small diameter portion 5d, restricting rightward movement of the second end portion 5b.

[0037] The double-bearing reel 100 includes a cylindrical component 40 and a second bearing 50. The cylindrical component 40 is integrally rotatably mounted to the handle shaft 5 between a first end 5a and a second end 5b. The cylindrical component 40 is disposed inside the boss portion 8a of the first side cover 8. The inner circumferential surface of the cylindrical component 40 is non-circular and fits into the outer circumferential surface of the handle shaft 5. The cylindrical component 40 has a protrusion 40a. The protrusion 40a protrudes radially from the outer circumferential surface of the cylindrical component 40. The protrusion 40a is formed circumferentially throughout the entire circumference of the cylindrical component 40. The protrusion 40a restricts the leftward movement of the second bearing 50.

[0038] The second bearing 50 is a rolling bearing that rotatably supports the handle shaft 5 via the cylindrical member 40. The second bearing 50 is disposed on the boss portion 8a of the first side cover 8. The inner ring of the second bearing 50 contacts the protrusion 40a in the axial direction. The axial movement of the second bearing 50 is restricted by the protrusion 40a and the boss portion 8a.

[0039] In the double-bearing winding reel 100 with the above-described structure, a first bearing 20 is disposed within a recess 5c located at the second end 5b of the handle shaft 5, and a roller clutch 30 is disposed on the outer periphery of the second end 5b of the handle shaft 5. That is, when viewed radially, the first bearing 20 and the roller clutch 30 are arranged to overlap axially. As a result, the enlargement of the handle shaft 5 can be suppressed axially, and the miniaturization of the winding reel body 2 can be achieved.

[0040] <Other Implementation Methods> The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment and various changes can be made without departing from the spirit of the invention.

[0041] In the foregoing embodiments, the present invention is applied to an electric winding reel, but it can also be applied to dual-bearing winding reels other than electric winding reels.

[0042] In the aforementioned embodiments, the first bearing 20 is composed of multiple rolling bearings 20a and 20b, but the first bearing 20 may also be composed of a single rolling bearing.

[0043] In the aforementioned embodiment, the frame 7 has a mechanism assembly plate 13, but the mechanism assembly plate 13 may also be omitted. In this case, the support shaft 10 and the support portion 13a may also be formed on the first side plate 11 of the frame 7.

[0044] In the aforementioned embodiment, the first bearing 20 is disposed within the recess 5c of the handle shaft 5, and the roller clutch 30 is disposed on the outer peripheral side of the second end 5b of the handle shaft 5. However, as Figure 3 As shown, the first bearing 20 can also be disposed on the outer periphery of the second end 5b of the handle shaft 5, and the roller clutch 30 can be disposed in the recess 5c of the handle shaft 5.
