US4850550A — Clutch mechanism for use in double bearing reel

Claim 1

Independent Claim 372 words

A clutch mechanism for a double bearing fishing reel comprising: a pair of opposed side plates; a spool shaft rotatably pivoted between said side plates; a pinion having an elongated axis and disposed to engage said spool shaft, a clutch means for selectively engaging and disengaging said pinion from said spool shaft; said clutch means including a clutch bar provided movably in the axial direction of said pinion to engage said pinion with and disengage said pinion from said spool shaft; said clutch means further including a clutch cam provided rotatably and concentrically with said spool shaft, having a first protrusion and a second protrusion, and being disposed to slide said clutch bar to cause said pinion and said spool shaft to be engaged and disengaged from each other; a handle for transmitting rotational force to said pinion to rotate said spool shaft in a first direction; a ratchet for preventing said handle from rotating said spool shaft in a direction other than said first direction; a rotatable push lever means pivotally provided between said side plates; a first interlocking lever having a first end fixed to said push lever means and a second end; a second interlocking lever rotatably pivoted on one of said side plates and having a first end arranged to engage said second end of said first interlocking member, and a second end arranged to engage said first protrusion of said clutch cam; and a U-shaped kick claw having an open end and an opposed closed end, and including a first claw portion, a second claw portion and a third claw portion, said open end for receiving said second protrusion of said cam member, said first claw portion for engaging said ratchet, said second claw portion for engaging said second protrusion of said cam member to rotate said cam member in a clockwise direction in response to the rotation of said ratchet in a clockwise direction, said third claw portion for engaging said second protrusion of said cam member to prevent said first claw portion from engaging said ratchet when said pinion is engaged with said spool shaft, and a kick claw spring attached to said kick claw for urging said first claw portion to engage said ratchet.

Claim 2

Dependent Claim 372 words

A clutch mechanism for a double bearing fishing reel comprising: a pair of opposed side plates; a spool shaft rotatably pivoted between said side plates; a pinion having an elongated axis and disposed to engage said spool shaft, a clutch means for selectively engaging and disengaging said pinion from said spool shaft; said clutch means including a clutch bar provided movably in the axial direction of said pinion to engage said pinion with and disengage said pinion from said spool shaft; said clutch means further including a clutch cam provided rotatably and concentrically with said spool shaft, having a first protrusion and a second protrusion, and being disposed to slide said clutch bar to cause said pinion and said spool shaft to be engaged and disengaged from each other; a handle for transmitting rotational force to said pinion to rotate said spool shaft in a first direction; a ratchet for preventing said handle from rotating said spool shaft in a direction other than said first direction; a rotatable push lever means pivotally provided between said side plates; a first interlocking lever having a first end fixed to said push lever means and a second end; a second interlocking lever rotatably pivoted on one of said side plates and having a first end arranged to engage said second end of said first interlocking member, and a second end arranged to engage said first protrusion of said clutch cam; and a U-shaped kick claw having an open end and an opposed closed end, and including a first claw portion, a second claw portion and a third claw portion, said open end for receiving said second protrusion of said cam member, said first claw portion for engaging said ratchet, said second claw portion for engaging said second protrusion of said cam member to rotate said cam member in a clockwise direction in response to the rotation of said ratchet in a clockwise direction, said third claw portion for engaging said second protrusion of said cam member to prevent said first claw portion from engaging said ratchet when said pinion is engaged with said spool shaft, and a kick claw spring attached to said kick claw for urging said first claw portion to engage said ratchet.

Claim 3

Dependent Claim 31 words

A clutch mechanism according to claim 1, wherein said rotatable push lever means comprises: rotatable push lever shaft; and a push lever fixed to said push lever shaft for rotation therewith.

Claim 4

Dependent Claim 42 words

A clutch mechanism according to claim 1, further comprising a kick claw shaft mounted on one of said side plates, said kick claw being rotatably and slidably mounted on said shaft and disposed to move between said clutch cam and said ratchet.

Claim 5

Dependent Claim 75 words

A clutch mechanism as set forth in claim 1, further comprising a flipping cam pivotally mounted on one of said side plates and a dead point spring having first and second ends, said dead point spring being attached at said first end to said clutch cam and at said second end to said flipping cam, said dead point spring being disposed to hold the clutch mechanism in either a pinion engaged or pinion disengaged position.
