ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a bait casting reel, and more particularly to a bait casting reel having a spool detaching mechanism to easily attach or detach a spool to or from the reel
2. Description of the Related Art
Bait casting reels are generally constructed in such a way that a pinion is rotated with a gear train driven in response to rotation of a handle, and a spool is rotated in the winding direction by transmitting the rotating force of the pinion to a spool shaft.
Such a bait casting reel comprises a driving shaft provided in one side plate of a red frame thereof and rotated in response to the rotation of the handle, and a plurality of gears meshed with a drive gear. The reel frame is provided with on the other side plate with a spool support. An example of such a bait casting reel having a spool support is disclosed in Japanese Unexamined Utility-Model Publication Nos. Hei 4-38267, Hei 5-60271, Hei 7-17064 and Japanese Utility-Model Publication No. Hei 8-10279.
According to the bait casting reel disclosed in the Japanese Unexamined Utility-Model Publication No. Hei 8-10279, the spool shaft provided in one side plate of the reel is rotatably supported by the bearing portion of the spool support inserted to be attachable and detachable to and from an opening formed on the one side plate of the reel. The bait casting reel comprises a proper number of engaging shoulders protruded radially and outwardly from an inner periphery of the opening, an engaging pin inserted in the side plate of the reel, the front end of which is biased toward the diametrical center of the opening by a spring to freely protrude from the inner periphery of the opening, an engaging edge protruded from the outer periphery of the spool support and having a cutout to receive the engaging shoulder when the support is inserted into the opening, and latch/unlatch recesses into which the engaging pin is inserted. The cutout is formed so that the engaging shoulder can be inserted and passed through.
With the construction the engaging edge can be engaged with the engaging shoulder to latch the spool support when the engaging pin is fitted into the latch recess, while the cutout of the engaging edge can be associated with the engaging shoulder to unlatch the spool support when the engaging pin is fitted into the unlatch recess.
The bait casting reel disclosed in Japanese Utility-Model Publication No. Hei 8-10279 has a problem that the axial length of the spool support is increased because the engaging edge with the cutout, and the latch and unlatch recesses must be formed in series in the axial direction on the same peripheral line of the spool support.
SUMMARY OF THE INVENTION
Accordingly, an object of the invention is to to solve the problems stated above, provide a bait casting reel having a spool detaching mechanism to easily attach or detach a spool to or from the reel.
Another object of the invention is to provide a bait casting reel with a spool detaching mechanism, which has a simple structure and can be easily opened with a single manipulation.
Still another object of the invention is to provide a bait casting reel which can minimize a clearance between the main body of the reel and the spool detaching mechanism for a smooth operation of the spool.
Still another object of the invention is to provide a spool detaching mechanism having a drag mechanism that can control the drag force of the spool.
To achieve the above and other objects, according to one aspect of the invention, there is provided with a bait casting reel for fishing including a reel frame having an opening, a spool rotatably mounted in the opening of the reel frame, and a spool cover, detachably engaged with the frame, for rotatably supporting the spool, the bait casting reel comprising:
the reel frame provided on an inner periphery of the opening with a first engaging protrusion having a predetermined number of cutouts, a second engaging protrusion and an engaging groove formed between the first and second protrusions and extended along the entire length of the inner periphery of the opening;
a locking member, provided adjacent to the opening of the reel frame, for contacting a portion of the spool supporting cover to prevent the cover from rotating; and
the spool supporting cover including a circular engaging edge engaged with the reel frame, and inserted into the cutout of the first engaging protrusion to guide the cover along the engaging groove.
According to another aspect of the present invention, there is provided with a bait casting reel for fishing including a reel frame having an opening, a spool rotatably mounted in the opening of the reel frame, and a spool detaching mechanism, detachably engaged with the frame, for rotatably supporting the spool, the bait casting reel comprising:
the reel frame provided on an inner periphery of the opening with a first engaging protrusion having a predetermined number of cutouts, a second engaging protrusion, and an engaging groove formed between the first and second protrusions and extended along the entire length of the inner periphery of the opening;
the spool detaching mechanism including a cover engaged with the opening of the reel frame, and drag means fixed onto the cover to apply drag force to the spool; and
the cover including a circular engaging edge engaged with the reel frame, and inserted into the cutout of the first engaging protrusion to guide the cover along the engaging groove, and a locking member provided adjacent to the opening of the reel frame.
In the embodiment, the locking member comprises a locking portion formed along an outer periphery thereof, and an unlocking portion formed adjacent to the locking portion and having an outer diameter smaller than that of the locking portion, the locking and unlocking portions being selectively positioned in a circular recess formed on an outer surface of the spool supporting cover as the locking member rotates.
The drag mechanism comprises an adjusting knob slightly protruded rotatably inserted through the opening at the center of the cover, a cylindrical spool support, a movable member having a shape of a hollow cylinder and threaded into the inner periphery of the adjusting knob, the movable member being moved axially by the rotation of the knob, a circular fixing plate connected to one end of the Movable member, and a pair of permanent magnets connected to the circular fixing plate.
