  • Fishing reel
    Patent number: 4421285
    Abstract: A fishing reel is disclosed as comprising a spool shaft having a spool supported to a reel body which has a pair of side walls opposite to each other, a pinion supported axially slidably and rotatably to said spool shaft, and a clutch provided between the spool shaft and the pinion, so that the spool shaft can be made freely rotatable relative to the pinion upon sliding movement of the pinion. The pinion has at an axially intermediate portion of its inner periphery an annular recess and at both axial sides thereof first and second bearing portions in contact with the outer periphery of the spool shaft. The spool shaft has at its outer periphery, and at a position opposite to the first bearing portion when the pinion axially slides to a position permitting the spool shaft to freely rotate, a smaller diameter portion which is larger in axial length than the first bearing portion.

  • Saddle support device for a bicycle
    Patent number: 4421357
    Abstract: A saddle support device for a bicycle, comprising a support member fixed to the upper portion of a seat post and a mechanism clamping a saddle frame and having a receiving member seated onto the support member and a holding member, said saddle frame being compressed between said receiving and holding members. The upper surface of the support member and the lower surface of the receiving member have spherical profiles, thereby making it possible to adjust the saddle not only in vertical angles longitudinally and laterally of the bicycle but also in rotation around the lengthwise axis of a locking member which draws the holding and receiving members together.

  • Fishing reel
    Patent number: 4418877
    Abstract: A fishing reel in which a fishing line can be wound on a spool through rotation of a rotary frame having a bail arm by operating a handle and the wound line can be drawn out of the spool for casting by turning over the bail arm, said spool having a first flange at a side with respect to the reel body, a cylindrical extension extending at the first flange toward the reel body, a third flange provided at the end of the cylindrical extension to thereby form a groove for receiving the fishing line, so that the fishing line, if backlash occurs during casting, can be prevented from falling between and being caught by the spool and the rotary frame.

  • Fishing reel
    Patent number: 4416428
    Abstract: A fishing reel, which supports a spool shaft having a spool which is movable in reciprocation longitudinal of a reel body, comprises a master gear having a first annular toothed portion for transmitting rotation to a rotary frame and a second annular toothed portion disposed at a position different in diameter from the first toothed portion, and an association shaft which has an association gear engageable with the second toothed portion and carries an engaging member engageable with a traverse groove provided at the spool shaft, so that the engaging member rotates following the rotation of the association shaft to allow the spool shaft to reciprocate longitudinally of the reel body, thereby avoiding longitudinal movement of the spool shaft in synchronism with rotation of the rotary frame.

  • Derailleur for a bicycle
    Patent number: 4406643
    Abstract: A derailleur for a bicycle, which is so constructed that a movable member is supported to a base member through two linkage members, a changeover frame having two pulleys carrying thereon a driving chain is pivoted to the movable member, and a tension spring is interposed between the movable member and the changeover frame, so that the tension spring exerts tension on the driving chain, said changeover frame being subjected to resistance against its swinging motion in a direction opposite to the working direction of the tension spring, thereby swinging the changeover frame easily in the direction of working of the changeover frame, while, requiring more force in the reverse direction to the working thereof, thereby making swinging of the changeover frame in the working direction of the tension spring easy and more difficult in the swinging motion direction opposite to the working direction of the spring.
