ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a spinning reel for fishing with a mechanism for preventing a reverse rotation of a rotor.
As disclosed in Japanese Laid-Open Publication No. 8-112049 and Japanese Utility Model Publication No. 2-5734, conventional spinning reels for fishing are provided with a reversal preventive mechanism for preventing a rotor from rotating in the direction of playing out a fishline during the operation of casting and taking up the fishline. The reversal preventive mechanism prevents the reverse rotation of a drive mechanism for rotatively driving the rotor.
The reversal preventive mechanism disclosed in Japanese Laid-Open Publication No. 8-112049 employs a rolling one-way clutch (a roller type one-way bearing), and functions to switch ON/Off the rotor (i.e., to make the rotor rotatable forwardly and reversely/to prevent the rotor from reversing) by utilizing the wedge action of the roller incorporated in the one-way clutch.
It is thus possible in view of the structure of the reversal preventive mechanism utilizing the wedge action of the roller to prevent the drive mechanism from reversing instantly when the rotor is reversed with a small degree of play in the reverse direction. On the other hand, this reversal preventive mechanism is often employed in mainly small-sized spinning reels because the reversal preventive force is insufficient.
The reversal preventive mechanism disclosed in Japanese Utility Model Publication No. 2-5734 employs a reversal preventive ratchet wheel and a reversal preventive pawl. An operating member is used to bring the reversal preventive pawl into engagement with and disengagement from the reversal preventive ratchet wheel so as to switch ON/OFF the rotor.
As the latter reversal preventive mechanism has strength greater than that of the rolling one-way clutch and is simple in structure, it is often employed in combination with a self-centering mechanism.
Such a conventionally known self-centering mechanism is used to hold the rotor in such a position that the fishline wound on a line roller may be picked up by the index finger of the hand gripping a fishing rod (hereinafter called the ‘centering position’) when terminal tackles are cast. As the spinning reel for fishing disclosed in Japanese Utility Model Publication No. 2-5734 is formed with the self-centering mechanism including a ratchet wheel having a single tooth and a retaining pawl engageable therewith, in addition to the reversal preventive ratchet wheel having a plurality of teeth and the reversal preventive pawl, the rotor may be held in the centering position by the self-centering mechanism when the reversal preventive mechanism is released.
Notwithstanding, the pointed-out drawback of the spinning reel for fishing disclosed in Japanese utility Model Publication No. 2-5734 is that a hooking miss tends to occur when matching a bite delays because a degree of play is great when the reversion is stopped as the reversal preventive mechanism essentially comprised of the reversal preventive ratchet wheel and the reversal preventive pawl.
SUMMARY OF THE INVENTION
An object of the present invention made in view of the aforementioned situation is to provide an improved arrangement for a spinning reel for fishing which is equipped with both a reversal preventive mechanism for preventing a rotor from rotating in the direction of playing out a fishline and a second reversal preventive mechanism such as a self-centering mechanism. The improved arrangement can make smaller a degree of play of the reversal preventive mechanism in the direction of reversing the rotor during the operation of taking up the fishline, and can surely prevent the rotor from rotating in the reverse direction.
In order to accomplish the object above, a spinning reel for fishing according to a preferable embodiment of the present invention comprises: a rotor rotatably supported in a reel body, a drive mechanism for driving the rotor by operating a handle mounted on the reel body, a first reversal preventive mechanism for preventing the rotor from rotating in the direction of playing out a fishline by preventing the drive mechanism from rotating in the reverse direction when the operation of casting and taking up a fishline is performed, and a second reversal preventive mechanism for holding the rotor in a predetermined position by preventing the drive mechanism from rotating in the reverse direction. The spinning reel is characterized in that the first reversal preventive mechanism is formed of a rolling one-way clutch and that switching the first reversal preventive mechanism to non-working condition causes the second reversal preventive mechanism to hold the rotor in the predetermined position.
If the first and second reversal preventive mechanisms are set in the working condition when the operation of casting and taking up the fishline is performed, the wedge action of the roller of the rolling one-way clutch in the first reversal preventive mechanism instantly stops the rotor from rotating in the direction of playing out the fishline.
Even though the rotor slips in the direction of playing out the fishline because of a strong tug of fish exceeding the capacity of the rolling one-way clutch, it is ensured that the rotor is prevented by the second reversal preventive mechanism from rotating in the reverse direction.
Further, switching the first reversal preventive mechanism to the non-working condition causes the second reversal preventive mechanism to hold the rotor in the predetermined position.
It is preferable that the spinning reel for fishing in further comprises a first operating portion for switching the working and non-working conditions of the first reversal preventive mechanism, and a second operating portion for simultaneously switching the working and non-working conditions of both the first and second reversal preventive mechanisms. The first operating portion is used for switching the working and non-working conditions of the first reversal preventive mechanism, and the second operating portion is used for simultaneously switching the working and non-working conditions of both the first and second reversal preventive mechanisms.
It is preferable that the first operating portion is urged in one direction so that the working condition of the first reversal preventive mechanism may be released only through the operation of an angler. The working condition of the first reversal preventive mechanism is released only when an angler operates the first operating portion, and the first reversal preventive mechanism returns to the working condition when the angler takes his hand off the first operating portion.
The present disclosure relates to the subject matter contained in Japanese patent application No. Hei. 10-299305 (filed on Oct. 21, 1998).
