Abstract
Abstract In a clutch mechanism for use in a fishing reel of the type wherein a pinion is coupled with or disconnected from a spool shaft by a clutch cam and a clutch bar so as to transmit or interrupt torque applied by an operating handle to the spool shaft. A kick lever is provided which is pivotally mounted on a cover of the clutch mechanism and operated by a push button, a slider pivotally connected to the kick lever, and a pawl pivotally mounted on the slider to engage and disengage a ratchet which is mounted on the cover. The pawl is maintained by a spring at a position slightly displaced from a line interconnecting an axis of the ratchet wheel and a center of rotation of the pawl thus avoiding arresting of the pawl by a tooth of the ratchet wheel.

Claim 1
Independent Claim
406 words
A clutch mechanism for a fishing reel comprising: a pinion; a cover member; means for mounting said pinion so as to be selectively reciprocated in an orthogonal direction relative to said cover member; a spool for retaining a fishing line; a spool shaft; means for rotatably mounting said spool and said spool shaft relative to said cover member; a clutch cam; an axis; means for rotatably mounting said clutch cam on said axis about said pinion; a clutch bar; means for reciprocatably mounting said clutch bar in a direction parallel to said pinion; a push button; means for pivotally mounting said push button relative to said cover member; means for operatively connecting said push button to said clutch cam for imparting rotary motion thereto; a kick lever having a first end; means for pivotally mounting said first end of said kick lever relative to said cover member; a pin being operatively mounted on said push button; a slot being positioned in a second end of said kick lever; a slot being positioned in said clutch cam; said pin of said push button being operatively mounted within said slot of said kick lever and said slot of said clutch cam to rotate said kick lever and said clutch cam when said push button is rotated; a ratchet wheel; an axis for rotatably mounting said ratchet wheel relative to said cover member; a slider; a pivot pin operatively mounted on said kick lever; means for mounting said slider on said pivot pin; a lug; means for affixing said lug to said slider; a kick pawl; means for pivotally mounting said kick pawl on said slider at a predetermined angle and said kick pawl being operatively pivotally mounted to selectively engage said ratchet wheel; spring means for normally biasing said kick pawl into engagement with said lug; a guide rod; means for securing said guide rod to said cover; said slider being rotatable about said pivot pin while being in engagement with the periphery of said guide rod; said kick pawl being selectively engageable with said ratchet wheel at a position slightly displaced from a line interconnecting said axis of said ratchet wheel and a center of rotation of said kick pawl when said push button is actuated and said clutch cam disengages said pinion from said spool shaft and said kick pawl being subsequently disengaged from said ratchet wheel by a subsequent slight rotation of said ratchet wheel.
Claim 2
Dependent Claim
406 words
A clutch mechanism for a fishing reel comprising: a pinion; a cover member; means for mounting said pinion so as to be selectively reciprocated in an orthogonal direction relative to said cover member; a spool for retaining a fishing line; a spool shaft; means for rotatably mounting said spool and said spool shaft relative to said cover member; a clutch cam; an axis; means for rotatably mounting said clutch cam on said axis about said pinion; a clutch bar; means for reciprocatably mounting said clutch bar in a direction parallel to said pinion; a push button; means for pivotally mounting said push button relative to said cover member; means for operatively connecting said push button to said clutch cam for imparting rotary motion thereto; a kick lever having a first end; means for pivotally mounting said first end of said kick lever relative to said cover member; a pin being operatively mounted on said push button; a slot being positioned in a second end of said kick lever; a slot being positioned in said clutch cam; said pin of said push button being operatively mounted within said slot of said kick lever and said slot of said clutch cam to rotate said kick lever and said clutch cam when said push button is rotated; a ratchet wheel; an axis for rotatably mounting said ratchet wheel relative to said cover member; a slider; a pivot pin operatively mounted on said kick lever; means for mounting said slider on said pivot pin; a lug; means for affixing said lug to said slider; a kick pawl; means for pivotally mounting said kick pawl on said slider at a predetermined angle and said kick pawl being operatively pivotally mounted to selectively engage said ratchet wheel; spring means for normally biasing said kick pawl into engagement with said lug; a guide rod; means for securing said guide rod to said cover; said slider being rotatable about said pivot pin while being in engagement with the periphery of said guide rod; said kick pawl being selectively engageable with said ratchet wheel at a position slightly displaced from a line interconnecting said axis of said ratchet wheel and a center of rotation of said kick pawl when said push button is actuated and said clutch cam disengages said pinion from said spool shaft and said kick pawl being subsequently disengaged from said ratchet wheel by a subsequent slight rotation of said ratchet wheel.
Claim 3
Dependent Claim
59 words
The clutch mechanism according to claim 1, wherein said ratchet wheel includes a plurality of teeth, said kick pawl being adapted to rotate about said pivot mount on said slider to ensure positive engagement between said kick pawl and said ratchet teeth when said push button is actuated and said clutch cam disengages said pinion from said spool shaft.
Claim 4
Dependent Claim
33 words
The clutch mechanism according to claim 1, wherein said slider includes a second lug operatively positioned to normally engage said kick lever to limit rotation of said slider relative to said kick lever.
Claim 5
Dependent Claim
26 words
The clutch mechanism according to claim 1, and further including a stop pin for limiting the rotation of said push button with respect to said cover.
