Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-bearing electric reel for fishing provided with a spool made of resin.

[0002]

2. Description of the Related Art A double-bearing electric reel for fishing uses a motor mounted inside a spool to reduce the size of the reel, as disclosed, for example, in Japanese Utility Model Laid-Open No. 6-34466. However, in a reel in which a motor is built in a spool, it is necessary to enhance the heat radiation effect of the motor. Therefore, it is necessary to form the spool from a metal material having a high thermal conductivity. In such a case, attempts have been made to make the spool thinner while securing its strength by making the spool from a forged aluminum product. However, forged aluminum products require a lot of time and effort in the processing process, and require rust prevention treatment.
There is a problem that the cost of parts increases. It has been attempted to manufacture the spool with aluminum die casting,
In that case, there is a problem that it is necessary to increase the wall thickness in order to secure the strength and increase the weight.

[0003] Since such a spool with a built-in motor always increases the size of the spool, it is more advantageous to dispose the motor outside the spool in order to reduce the diameter of the spool. . 6-603
No. 66 and Japanese Utility Model Laid-Open Publication No. 7-25766 propose a double-bearing type electric reel for fishing in which a motor is arranged outside a spool.

[0004]

However, even in the conventional double-bearing type electric reel for fishing in which the motor is disposed outside the spool, the spool is made of metal such as aluminum, so that there is a problem of weight reduction. Still exists. If the spool is made of a synthetic resin or the like other than metal, the weight can be reduced, but there is a new problem of insufficient strength.

Accordingly, an object of the present invention is to provide a means for further reducing the weight of a dual-bearing electric reel for fishing in which a motor is disposed outside a spool.

[0006]

In order to achieve the above object, the invention of claim 1 is directed to a side plate (2, 2) of a reel body (1).
3) A double-bearing type for fishing in which a spool (4) is rotatably mounted between the spools, and the spool (4) is wound by a winding device (7, 8 or the like) mounted on the reel body (1). In the electric reel, the spool (4) is made of a resin material, and a reinforcing member (30, 3) is attached to the spool (4).
5, 41, 43) are integrally mounted, and a double-bearing electric reel for fishing is adopted.

[0007] The invention according to claim 2 provides a reinforcing member (3
0, 35, 41, 43) are provided on both sides (4a, 4b) of the spool (4) or on the inner periphery of the fishing line winding body (4c) of the spool (4). A double-bearing electric reel for fishing is adopted.

[0008] The invention according to claim 3 provides a reinforcing member (3
0, 35) is constituted by a part of a speed reduction mechanism.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings.

Embodiment 1 As shown in FIG. 1, a double-bearing type electric reel for fishing uses side plates 2 on left and right frame plates 1a and 1b of a reel body 1.
3 and a spool 4 between both side plates 2 and 3. The spool 4 is rotatably supported by left and right frame plates 1a and 1b via ball bearings 5 and 6, and a handle 7
Alternatively, it is turned by a winding device driven by a motor 8 as described below.

As shown in FIGS. 1 and 2, the handle 7 is provided outside the reel body 1, and a handle shaft 7a is rotatably supported between the right frame plate 1b and the side plate 3. A master gear 10 is attached to the handle shaft 7a via a drag device 9. When the handle 7 is turned, the master gear 10 rotates integrally with the handle shaft 7a due to frictional resistance via the drag device 9.

A pinion shaft 11 is provided between the right frame plate 1b and the side plate 3 in parallel with the handle shaft 7a.
13 is supported. A pinion 14 is slidably mounted on the pinion shaft 11. The pinion 14 is always meshed with the master gear 10. A clutch claw 15 is formed between the left end of the pinion 14 and an intermediate position of the pinion shaft 11. The pinion 14 and the pinion shaft 11 indicated by a solid line in FIG. 2 are in a state where the clutch pawl 15 is engaged (clutch ON). When the handle 7 is turned in the winding direction of the fishing line in this state, the handle shaft 7a,
Torque is transmitted to the spool 4 via the master gear 10, the pinion 14, the pinion shaft 11, and first and second planetary gear units 16 and 17, which will be described later, and the spool 4 winds the fishing line. Conversely, when the clutch claw 15 is released (clutch OFF), the spool 4 is dynamically disconnected from the handle 7 and becomes free to rotate, and the fishing line is paid out by the weight of the device or the like.

The turning on and off of the clutch by engaging and disengaging the clutch pawl 15 is operated by a lever device. That is, an annular groove is formed at an intermediate position of the pinion 14,
A shifter 18 fits into the annular groove. A clutch cam 19 disposed so as to surround the clutch pawl 15 is rotatably held on the frame plate 1b of the reel body 1, and a cam piece 19a of the clutch cam 19 is in contact with the shifter 18. The shifter 18 is constantly urged by a coil spring (not shown) in a direction such that the clutch ON state is maintained. A clutch lever 20 is attached to the outside of the side plate 3 of the reel, and a link 21 is provided between the clutch lever 20 and the clutch cam 19.
Thus, when the clutch lever 20 is switched to the clutch ON, the clutch cam 19 rotates in a direction to release the shifter 18, the pinion 14 slides on the pinion shaft 11, and the clutch claw on the left end of the pinion 14 15 engages with the clutch pawl 15 on the pinion shaft 11, so that the spool 4 can be rotated by operating the handle 7. Conversely, when the clutch lever 20 is switched to the clutch OFF state, the clutch cam 19 is
8 is displaced to the right, the pinion 14 slides rightward on the pinion shaft 11, and the clutch claw 15 at the left end of the pinion 14 is separated from the clutch claw 15 on the pinion shaft 11, so that the spool 4 can freely rotate. .

On the other hand, a motor 8 for rotating the spool 4 is fixed horizontally between the left and right frame plates 1a and 1b of the reel body 1 via a cylindrical motor case 22. The motor 8 is driven by a battery (not shown). The switches for driving and stopping the motor 8 are provided in a control box (not shown) mounted on the upper portion of the reel unit 1.

As shown in FIGS. 1 and 3, the power generated by the motor 8 is transmitted to the spool 4 via a gear train 23 and a speed reduction mechanism including first and second planetary gear units 16 and 17.
Is transmitted to A gear box 24 is attached to the left frame plate 1a, and a gear train 23 and a second planetary gear set 17 are housed in the gear box 24. Motor 8

4, various intermediate gears 23b, 23c, 23d,
The power is transmitted to the driven gear 23f via 23e and 23f.
The shaft 26 that holds the driven gear 23f is pivotally supported by the frame plate 1a so as to pass through the center of the ball bearing 5 that supports the left end of the spool 4.

As a result, when the motor 8 is started, the gear train 23 and the first and second planetary gear units 16, which will be described later,
The torque is transmitted to the spool 4 via 17 and the spool 4 winds up the fishing line. When the power of the motor 8 is turned off, the spool 4 is interlocked with the handle 7. When the clutch is turned off by operating the handle 7, the spool 4 becomes freely rotatable, and the fishing line is paid out by the weight of the device or the like.

The first and second planetary gear units 16 and 17 are in an interlocking relationship. When the spool 4 is turned by operating the handle 7, the rotation speed of the handle 7 is slightly increased and transmitted to the spool 4, and the motor is rotated. When the spool 4 is rotated by the power of 8, the rotation speed of the motor 8 is reduced and transmitted to the spool 4.
