Abstract

A spinning type fishing reel, including a spool shaft, a spool mounted on the spool shaft so as to be rotationally fixed with respect thereto and so as to be axially movable with respect thereto, and an adjustment member mounted on the spool shaft so as to be rotationally movable with respect thereto and so as to be axially fixed with respect thereto. A screw drive assembly includes a male threaded construction coaxial with the spool shaft and a female threaded construction screwingly cooperating with the male threaded construction and also coaxial with the spool shaft. One of the male and female threaded constructions is fixed with respect to the adjustment member, and the other of the male and female threaded constructions is fixed with respect to the spool. When the adjustment member is rotated with respect to the spool and the spool shaft, with the spool remaining rotationally stationary with respect to the spool shaft, this rotates the male and female threaded constructions with respect to one another, thus causing them to be axially moved with respect to one another by their mutual screwing action; and this axially drives the spool with respect to the adjustment member and the spool shaft. This provides a way of adjusting the axial position of the spool on the spool shaft, so as, when winding up the fishing line on the spool, to avoid either the excessively front wound condition or the excessively back wound condition.

Dependent claims

A spinning type fishing reel, comprising:

(a) a spool shaft having a tapered end and an annular groove adjacent said tapered end;
(b) a spool mounted on said spool shaft so as to be rotationally fixed relative thereto and axially movable thereon;
(c) an adjustment mechanism mounted on said spool shaft so as to be axially fixed relative thereto and rotationally movable thereon, said adjustment mechanism for adjusting the axial position of said spool relative to said spool shaft;
(d) a screw drive assembly, comprising a male threaded construction coaxial with said spool shaft and a female threaded construction threadedly cooperating with said male threaded construction and also coaxial with said spool shaft, one of said male and female threaded constructions being fixed relative to said adjustment mechanism, and the other of said male and female threaded constructions being fixed relative to said spool;
(e) stepping mechanism means for providing stepwise motion between said adjustment mechanism and said spool;
(f) a shaft grip spring mounted to said adjustment mechanism and substantially fixed thereto with regard to relative movement therebetween in the axial direction, said spring having an engagement portion which engages said spool shaft annular groove and retains said adjustment mechanism and said spool on said spool shaft;
and
(g) a release mechanism mounted with said adjustment mechanism for releasing said spool and adjustment mechanism from said spool shaft by releasing said spring from said shaft annular groove, said release mechanism comprising a push button having a tapered end spring engaging surface for separating said spring from said annular groove.
