Description

[Detailed description of the invention] [Industrial application field] This invention relates to a fishing reel that can be used both manually and electrically, and its technical feature is that switching between manual and electrical operation can be performed automatically. That is.

[Conventional technology and its problems]

Traditional manual and electric fishing reels are
For example, when an excessive load is applied to the line or the motor breaks down, switching from electric to manual, or vice versa, can be done by operating a separate lever or button, and when electric In order to prevent the manual handle from rotating together, when the handle and the drive shaft of the spool can be separately engaged and disengaged manually, a two-step switching operation is required each time. In addition to problems with switching, the internal mechanism was complicated, which hindered efforts to make the reel lighter and smaller.

[Means for solving problems]

Therefore, the present invention includes a clutch shaft that can be freely engaged and disengaged from the spool shaft, a drive shaft that interlocks with the clutch shaft,
A handle is connected to the drive shaft through a co-rotation prevention mechanism consisting of a ratchet gear and a pawl, and an intermediate gear that meshes with a transmission gear fixed to the drive shaft is provided at one end, and a roller clutch is provided at the other end. It consists of a drive shaft having another intermediate gear attached thereto, and a motor that drives the another intermediate gear, and further, the rotation of the drive shaft by the motor is disconnected from the handle side through the co-rotation prevention mechanism. By doing so, the above-mentioned problems could be solved.

[Effect]

By intervening the roller clutch, the present invention allows the drive shaft to be rotated manually or electrically, whichever side rotates faster, without requiring the operation of a separate lever, while the above-mentioned co-rotation prevention mechanism This has the effect of preventing the handle from interlocking during electric operation.

〔Example〕

Hereinafter, the structure will be described in more detail according to the embodiment shown in the drawings. In FIG. It has a built-in electric mechanism on one side and a conventional auto-return type manual mechanism operated by the rotation of the handle on the other side.

The manual mechanism allows the clutch shaft 4 to be slid in the axial direction by operating a lever 3 provided on one side to engage and disengage from the shaft of the spool 2, while being tightened by the drag 5. A master gear 8 on a drive shaft 7 having a built-in movable multi-plate clutch 6 is engaged with the clutch shaft 4, and the clutch shaft 4 is moved in a certain direction (winding direction) through a handle 9 at one end of the drive shaft. direction).

The clutch shaft 4, which is separated from the spool 2, can be released by rotating the handle 9 by a certain amount, which is activated via a protrusion 10' on a transmission gear 10 provided on the drive shaft. Due to the mechanism,
It returns elastically and engages with the spool shaft.

On the other hand, the electric mechanism includes a motor M, a drive gear 11 on the motor shaft, and the drive gear 1.
A roller clutch 13 is connected between the reduction gear 12 and the transmission gear 10 on the drive shaft 7.
The rotation of the motor M can be transmitted to the drive shaft 7 and the clutch shaft 4 by a drive shaft 15 having intermediate gears 14, 14'.

Further, the handle 9 of the drive shaft 7 is provided with a mechanism A to prevent co-rotation with the drive shaft 7 when the motor rotates, and at the same time, the drive shaft 7 can be wound on the spool at any time without requiring a separate switching operation. The drive shaft 7 is configured so that it can be rotated only in the taking direction, and as an example, as shown in FIG. 2, the drive shaft 7
While the handle 9 is rotatably attached to the outer end of the
Ratchet gear 16 fixed to the drive shaft 7
and a claw 17 pivotally supported on the handle 9 by a spring 1.
8, so that they can be elastically engaged.
In addition to the spring 18 shown in FIG. 2, various other elastic materials can be selected, such as a silent spring that presses the side surface of the gear 16 or a plate spring.

Therefore, according to the above mechanism, even if the drive shaft 7 is rotated by the motor M in the direction of the arrow in the figure (the winding direction of the yarn), the ratchet gear 16 and the pawl 17 do not engage with each other, so that the handle 9 can be reliably prevented from rotating together, and by rotating the handle 9 in the winding direction at a higher speed than the drive shaft 7 by the action of a roller clutch 13 as will be described later, the ratchet gear 16 and pawl 17 are engaged. This allows the drive shaft 7 to be rotated manually.

Therefore, in the fishing reel of the present invention, when the motor M is normally started, the intermediate gear 14' and the drive shaft 15 are rotated together by the roller clutch 13, so that the rotation of the motor M is driven. This signal is transmitted to the shaft 7, and the spool 2 can be wound up via the clutch shaft 4.

On the other hand, if the motor M decelerates significantly due to an overload on the line, as when catching a large fish, for example, the drive shaft 7 can be moved in the winding direction of the spool via the handle 9 to reduce the electric speed. By rotating the spool 2 at a speed exceeding 1, the drive shaft 15 is insulated from the reduction gears 12 and 12' by the action of the roller clutch 13, so that the spool 2 can be manually wound. It is something.

Also, at this time, if the overload on the motor is reduced to some extent and the rotation of the drive shaft by the motor exceeds the number of rotations of the handle, it is possible to return to electric power again without requiring any switching operation. be.

In addition, even if the motor M breaks down or if it becomes necessary to stop the motor M and perform winding only manually, you can simply rotate the handle 9 according to the principle described above, without switching. It can fully function as a manual reel.

[Effect of idea]

As mentioned above, the proposed fishing reel can be used either manually or electrically by the roller clutch.
Since the drive shaft can be rotated on whichever side rotates faster, it is possible to automatically switch between manual and electric modes, eliminating the need for the complicated switching operations required in the past. When the reel is electric, it does not rotate together, and when it is manual, it can be operated immediately without any change on the handle side, and its structure is extremely simple, so it does not interfere in any way with making the reel lighter and more compact. It brings about excellent effects that could not be expected from conventional manual/electric reels of this type.
