Description

Technical Field

[0001] The present invention relates to an electric fishing reel. Background Art

[0002] Conventionally, various electric fishing reels are known as electric fishing reels that include a drag mechanism.

[0003] For example, Patent Document 1 discloses an invention relating to a dual-bearing reel for releasing a fishing line forward, the reel comprising a rotation transmission mechanism for transmitting rotation of a handle in a line-reeling direction to a spool, and a drag mechanism. The rotation transmission mechanism comprises: a reel body; a handle rotatably provided on a side portion of the reel body in the line-reeling direction; a spool that rotates in the line-reeling direction in conjunction with the rotation of the handle in the line-reeling direction; and a drive shaft rotatably coupled to the handle. The drag mechanism brakes rotation of the spool in the line-releasing direction, the reel comprising: an operating member rotatably engaged with an outer circumferential surface of the drive shaft and movable in an axial direction relative to the drive shaft by relative rotation with the drive shaft; and a friction mechanism disposed on the drive shaft for varying the drag according to the amount of axial movement of the operating member. The operating member is moved in a direction in which the drag increases by rotating relative to the drive shaft in a direction opposite to the line-reeling direction of the handle.

[0004] Patent Literature

[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2014-212739 Summary of the Invention

[0006] In the electric fishing reel described in Patent Document 1, when the drag is released, the nut inside the star drag wheel moves away from the drive gear, creating a gap between the brake components. This gap is absorbed by the spring washer. However, if the drag is continuously tightened, there is a risk that the spring washer will creep or wear out due to repeated use, preventing the gap from being fully absorbed by the spring washer. This can lead to loosening of the drive gear and brake components, potentially causing the handle's reverse-rotation stopper to fall off.

[0007] In recent years, demands have been placed on achieving both a more compact and higher drag force and lower drag-free performance. As a primary method for improving drag force, increasing the number of drag washers is known. The conventional method described in Patent Document 1 prevents the drive gear from moving toward the handle even when the drag force is released and looseness occurs by providing ribs on the upper portion of the drag mechanism. However, this method suffers from the problem of being unable to increase the number of drag washers due to the presence of ribs on the upper portion of the drag mechanism.

[0008] The present invention solves the problems of the above-mentioned prior art. The technical problem to be solved is to provide an electric fishing reel that can change the structure of the drag washer without changing the basic shape of the side plate on the handle side, can avoid handle reversal and prevent malfunction of the limiter, and can significantly reduce development costs and equipment investment by sharing the basic structure for various models.

[0009] In order to achieve the above-mentioned object, the present invention is an electric fishing reel comprising: a left frame and a right frame; a left side plate and a right side plate covering the left frame and the right frame; a rotatable handle provided on either the left frame or the right frame and a handle shaft rotating integrally with the handle; a driving gear rotatably frictionally coupled to the handle shaft; and a drag washer fixedly engaged with the handle shaft and provided on the end portion of the handle shaft on the direction side of the driving gear.

[0010] It is characterized in that

[0011] The left plate or the right plate provided with the handle is provided with a protrusion protruding from the inner side thereof toward the driving gear, and an end of the protrusion is spaced apart from the driving gear by a distance of 3.0 mm or less.

[0012] In the electric fishing reel according to one embodiment of the present invention, the end of the protrusion is spaced apart by a distance of 3.0 mm or less from the upper surface of the tooth surface of the drive gear as viewed in the direction of the handle shaft.

[0013] In the electric fishing reel according to one embodiment of the present invention, the end of the protrusion is spaced apart by a distance of 3.0 mm or less from the upper surface of the cylindrical portion housing the drive gear as viewed in the direction of the handle shaft.

[0014] In the electric fishing reel according to one embodiment of the present invention, the protrusion is formed integrally with or separately from the left side plate or the right side plate.

[0015] In the electric fishing reel according to one embodiment of the present invention, the protrusion is a rib formed in a C-shape along the circumferential direction of the handle shaft.

[0016] According to the present invention, the structure of the drag washer can be changed without changing the basic shape of the side plate on the handle side, the handle reversal prevention limiter malfunction can be avoided, and the development cost and equipment investment can be greatly reduced by sharing the basic structure for various models.

DETAILED DESCRIPTION

[0024] Below, embodiments of the electric fishing reel according to the present invention are described in detail with reference to the accompanying drawings. Common components in the multiple drawings are designated by the same reference numerals throughout the drawings. For ease of explanation, the drawings are not necessarily drawn to scale; please note this.

[0025] Figure 1The basic structure of an electric fishing reel 1 according to one embodiment of the present invention is shown. The electric fishing reel 1 can wind the fishing line onto a spool 2 and can switch between a state in which the fishing line can be released from the spool 2 and a state in which the fishing line cannot be released. When a tension exceeding a set value is applied to the fishing line, the spool 2 idles (drain function). In addition, a threshold tension can be set, and the braking force used to prevent recoil when the fishing gear is dropped or cast can be adjusted.

[0026] The electric cable reel 1 includes a cable reel body 10 having a left frame 3a and a right frame 3b spaced apart from each other, and a left side plate 4a and a right side plate 4b covering the left frame 3a and the right frame 3b, respectively. A reel 2, a motor (electric motor) 5, a drive gear 6, and a drag mechanism 7 are provided between the left and right frames 3a and 3b (the details of the drive gear 6 and the drag mechanism 7 will be described later). A handle shaft 8 is rotatably supported on the right frame 3b and the right side plate 4b, and an operating portion, namely a handle 9, is mounted on its end. In this embodiment, an example is adopted in which the handle shaft 8 and the handle 9 are provided on the right frame 3b side, but the handle 9 may also be provided on the left frame 3a.

[0027] The left and right frames 3a and 3b constitute the skeleton of the reel body 10 and are formed of a metal material such as aluminum alloy or magnesium alloy, but are not limited thereto. The left and right frames 3a and 3b are integrated by a plurality of pillars (not shown).

[0028] The spool 2 can be rotationally driven in the fishing line reeling direction by the rotational drive of the motor 5 and the reduction mechanism etc. The reduction mechanism is provided on the left frame 3a side and reduces the output of the motor 5.

[0029] The left end of the handle shaft 8 is supported on a bearing provided on the right frame 3b. The bearing is locked with the annular anti-falling component and will not fall off. In addition, the ratchet (not shown), the transmission gear (not shown), and the drive gear (not shown) arranged on the handle 9 side closer than the bearing are also constructed so as not to fall off from the handle shaft 8. In addition, a washer (not shown) is sandwiched between the transmission gear and the ratchet so that the ratchet does not directly abut against the transmission gear. As a result, when the drive gear and the transmission gear rotate relative to the handle shaft 8, they are not easily affected by friction with the ratchet.

[0030] The ratchet has a sawtooth shape and is a gear that is used to transmit the rotational driving force of the retracting operation of the handle 9 to the clutch mechanism, or to engage with the claw member to prevent the reverse rotation of the handle shaft 8. In addition, a power release mechanism 7 is formed on the right side of the driving gear.

[0031] When the power transmission mechanism is in the power transmission state (clutch ON), the force exerted on the fishing line by the fish pulling in is transmitted to the drive gear via the spool 2 (spool shaft, pinion gear). Here, the drive gear is frictionally engaged with the handle shaft 8, which prevents reverse rotation, via the drag mechanism 7. Therefore, when the force transmitted to the drive gear is greater than the frictional engagement force (braking force) with the drag mechanism 7, the drive gear rotates about the handle shaft 8.

[0032] As a result, when the force of pulling back the fish is very large, the reel 2 will rotate and pull out the fishing line to prevent the cutting of the fishing line. In addition, the handle shaft 8 can prevent the reversal of pulling out with the fishing line by roller-type one-way clutch and ratchet.

[0033] The drag mechanism 7 that applies braking force to the drive gear includes a star drag wheel 13 that presses a component passing through the handle shaft 8 toward the drive gear, and a brake portion 14 that passes through the handle shaft 8 and is pressed by the star drag wheel.

[0034] The brake portion 14 of the drag mechanism 7 includes a drag washer 15. The drag washer 15 is housed inside a cylindrical portion (drag housing portion) 16 of the drive gear and is fitted to the handle shaft 8 so as to be axially movable and rotationally fixed.

[0035] Figure 2 This figure shows the structure of the protrusion 20 that protrudes from the inner side of the left side plate 4b covering the left frame 3a toward the drive gear 6. The protrusion 20 is formed integrally with the left side plate 4b and is arranged so that its end (end face) 21 is spaced apart from the upper surface 22 (for example, the cylindrical end face formed with the tooth face 17) of the drive gear 6 as viewed in the direction of the handle shaft 8 by a distance of less than 3.0 mm. By providing this protrusion 20, even if the deceleration force is released and the drive gear 6 attempts to move toward the handle side, the end 21 of the protrusion 20 will contact the tooth face 17 of the drive gear 6, thereby limiting the movement of the drive gear 6. As a result, there is no need to provide ribs on the upper part of the deceleration mechanism 7, and the number of deceleration washers can be changed. In addition, for the same reason, it is also possible to improve the handle reversal prevention limiter malfunction.

[0036] Figure 3 This figure shows another embodiment of the protrusion 20. This protrusion 20 is formed as a pin that is separate from the left side plate 4b covering the left frame 3a. As in the previous embodiment, this pin is positioned at a distance of 3.0 mm or less from the upper surface 22 of the tooth surface 17 of the drive gear 6, as viewed in the direction of the handle shaft 8. By separating the protrusion 20 from the left side plate 4b, manufacturing costs can be reduced compared to an integral manufacturing method.

[0037] Figure 4The end portion (end portion) 21 of the protrusion 20 is configured to be spaced at a distance of 3.0 mm or less from the upper surface 23 of the cylindrical portion 16 housing the drive gear 6, as viewed in the direction of the handle shaft 8. Since the gear side of the drive gear 6 is formed on the cylindrical portion 16 housing the drive gear 6, even if the force is released and the drive gear 6 attempts to move toward the handle, the end portion 21 of the protrusion 20 contacts the cylindrical portion 16 housing the drive gear 6, thereby restricting the movement of the drive gear 6.

[0038] Figure 5 1 is an example of a protrusion 20 involved in further other embodiments, and the protrusion 20 is configured as a C-shaped rib along the circumference of the handle shaft 8. The C-shaped rib can be formed, for example, into the largest circle except for the pinion. As in the above-mentioned embodiments, the end of the rib is set to be spaced apart from the tooth surface 17 or the cylindrical portion 16 of the drive gear 6 by a distance of less than 3.0 mm. In addition, the shape of the rib is not limited to the C-shape, and can also be, for example, a semicircular shape or a shape composed of multiple pins. That is, the protrusion 20 only needs to have the function of limiting the movement of the drive gear 6 toward the handle side.
