  • Patent number: 7178751
    Abstract: A fishing reel comprising an improved bail and/or spool system. In one example of the fishing reel, an improved bail and spool system may be adapted to facilitate casting of the fishing line. In another example of the fishing reel, an improved bail and spool system may facilitate retrieval of the fishing line. For instance, the spool may be adapted to rotate and discharge a fishing line. The spool may also be adapted to oscillate such as during retrieval of the fishing line. On the other hand, the bail may be adapted to pivot between an engaged position and a disengaged position such as for casting and retrieval of the fishing line. However, the bail may be adapted to remain stationary during rotation or oscillation of the spool (e.g., such as during casting or retrieval of the fishing line). An example of the fishing reel may also include a release assembly. For example, the bail may be adapted to engage a portion of a lock that may be positioned in a lock housing.

  • Patent number: 6971600
    Abstract: The invention compensates or normalizes for the non-linear oscillation speed of the spool in a fishing reel through use of a special shaped guide slot. The guide slot can be shaped through combining a number of curves into the length of the slot. In particular, for each end of the guide slot there is contained a curvature section, such that both ends of the guide slot are curving toward the spool side in one design or away from the spool in the other design. This general shape of the guide slot improves the contact position between the pole and the level wind bracket, and also compensates for the non-linear speed of the spool. The shape of the guide slot also reduces the wobbling or jiggling that occurs during operation of the reel when compared to conventionally designed reels.

The guide slot of the instant invention is asymmetrically constructed to produce, in a two-cycle-type spool movement arrangement, one spool velocity profile in the forward direction and a different spool velocity function in the rearward direction. In the preferred embodiment, the two velocity profiles (asymmetries of the guide) will be chosen to be complementary in the sense that imperfections in the velocity function in one direction can be compensated for to some extent during movement in the second cycle.

  • Patent number: 5941470
    Abstract: A fishing reel oscillation system having a rotating pawl oscillation assembly whose components are integrated into a standard fishing reel mechanism wherein a pawl attached to a pinion rotates around a main shaft with a lead-screw recess track, causing the shaft and an attached spool to oscillate along the rotational axis of the spool. The pinion is also coupled to a rotor. In this manner, one integrated mechanism effects both the oscillation of the spool and the spinning of the rotor.

  • Patent number: 5921489
    Abstract: A fishing spinning reel includes an oscillate mechanism in which a protrusion is formed on the periphery of an idle gear which turns in association with the rotation of a handle. The protrusion engages with an oscillate groove of an oscillate slider which is provided on the rear end side of a spool shaft having a spool at the end. Thus, rotation of the handle is converted into the reciprocation of the spool to move the spool back and forth. In the fishing spinning reel, the oscillate groove includes: an inclined portion which is inclined in the front-to-rear direction of the spool shaft; and straight portions which extend respectively from both ends of the inclined portion in such a manner that the straight portions are substantially perpendicular to the spool shaft.

  • Patent number: 5683047
    Abstract: A fishing spinning reel which is compact, yet operates stably even when exposed to unfavorable conditions. A part of a rotor (16) provided around a rotary shaft (16J) of the rotor is formed into a cylindrical protrusion (16C). The cylindrical protrusion (16C) is so arranged that, at least when a spool (18) is retracted to the rearmost position, the cylindrical protrusion (16C) of the rotor enters the spool from behind. The front end portion of a reel housing (10) is similarly formed into a cylindrical protrusion (10M). The cylindrical protrusion (10M) of the reel housing (10) is set within the cylindrical protrusion (16C) of the rotor. At least essential parts (e.g., a transverse cam shaft 24 and a slider 26) of a mechanism for moving the spool (12) back and forth are provided in an available space between a handle shaft (14) to which a handle (12) is connected and a front wall of the cylindrical protrusion (10M).

  • Patent number: 5427324
    Abstract: A spinning reel for fishing which guides a slider slidably in a manner to restrict the play and clatter of the slider in the rotational direction by a plurality of engaging portions. The durability and strength of the slider are also enhanced. On the inner surface of the reel casing facing the slider, there are provided a first plane-shaped engaging portion and an L-shaped projecting portion, while a second engaging portion is formed on the inside surface of the projecting portion. The slider includes a first sliding contact surface for sliding contact with the first engaging portion, and a second sliding contact surface formed in a projection to be inserted into the L-shaped projecting portion for sliding contact with the second engaging portion.

  • Patent number: 5368246
    Abstract: A spincasting reel is made up of an outer housing, a shaft extending through the housing including a line spool and nose portion at one end of the shaft externally of the housing with the fishing line extending away from the spool in the gap formed between the nose portion and housing. A line pick-up member extends across the annular gap and reciprocates with the nose portion when the fishing line is reeled in by a manual crank; and in releasing the line from the spool during the casting stroke the line pick-up member and nose portion are both latched in positions out of the path of movement of the line. As a preliminary to casting, a temporary restraint member may be advanced into engagement with the nose to prevent line release from the spool, and a drag control mechanism is associated with the shaft to apply a predetermined resistance to rotation of the spool and tension on the line when it is released from the spool.

  • Patent number: 5350131
    Abstract: In a fishing reel of the type in which the spool for receiving the fishing ine is caused to move to and fro in the direction of its winding axis in response to a cam drive for driving a spindle attached to the spool, the cam drive including a guide part with a guide slot into which projects an eccentrically mounted cam stud, the guide slot is in the form of an elongated S in order to impart an acceleration to the spool at its reversing points, and thereby prevent formation of bulges at the sides of the spool during winding. The locations in the guide slot corresponding to reversing points of the spool are offset from a center line of the guide slots along a longitudinal axis of the slot in a direction perpendicular to the stroke direction, resulting in the above-described acceleration and also having the effect of increasing displacement of the cam drive mechanism in the stroke direction.

  • Patent number: 5167381
    Abstract: An oscillating mechanism in a fixed-spool fishing reel of the closed-face type has a supporting plate mounted in the frame of the fishing reel. The reel has a handle whose shaft extends through the supporting plate. A first gear is nonrotatably connected to the shaft of the handle. A second gear is supported by the supporting plate and meshes with the first gear. The second gear has a smaller diameter than the first gear and carries an eccentric pin. A slide is connected to the line spool of the fishing reel for oscillating the line spool when the handle is turned. The slide has an elongate recess in which the eccentric pin engages for oscillating the slide and, hence, the line spool when the handle is turned. The slide further has a guide slot in which the shaft of the handle engages as a guide pin.
