Abstract

A level winder for a double-bearing reel for a fishing rod consists of a traverse cam shaft held between portions of frame bases on side walls in front of a spool. The cam shaft is rotated by a driving gear mounted on a handle shaft and includes a guide cylinder mounted around an outer portion of the traverse cam shaft, and rotatably supported between the frame bases. A slidable member is mounted around the guide cylinder and moves reciprocally along the guide cylinder in a lateral direction. A locking recess is formed at a front portion of the slidable member and includes smooth guide surfaces formed on portion of the slidable member on either side of the locking recess; notches formed in upper portions of the locking recess; a pair of upper and lower guide rods supported between the side walls; right and left line guide arms mounted slidably on the guide rods and urged resiliently in opposite directions by a spring; and locking pins projecting from rear portions of the line guide arms, being retractable into the line guide arms and engaging with the locking recess so that a fishing line guide portion is formed between the two line guide arms; the locking pins being dispensed from the locking recess through the notches when the slidable member is rotated.

Dependent claims

In a double-bearing reel for a fishing rod, said reel having side walls, frame bases on said side walls and a handle shaft, and including:

a spool shaft supported rotatably between said side walls of said reel and having a spool attached therearound;
a driving gear on said handle shaft;
a pinion mounted on one end portion of said spool shaft, for meshing with said driving gear, said pinion engaging with, and disengaging from, said spool shaft;
clutch means for causing said pinion to unitarily engage with, and disengage from, said spool shaft;
and
clutch-returning means for actuating said clutch means in the interlocking arrangement when said handle shaft is rotated in the direction in which a fishing line is wound in, whereby said pinion that has been disengaged from said spool shaft can be unitarily engaged with said spool shaft;
a level winder comprising:
a traverse camshaft held between portions of said frame bases on said side walls in front of said spool, said traverse camshaft being rotated by said driving gear mounted on said handle shaft;
a guide cylinder mounted around an outer portion of said traverse camshaft, and rotatably supported between said frame bases;
a slidable member mounted around said guide cylinder, for rotating unitarily with said guide cylinder and moving reciprocally along guide cylinder in a lateral direction;
a locking recess formed at a front portion of said slidable member;
smooth guide surfaces formed on portions of said slidable member on either side of said locking recess;
notches formed in upper portions of said locking recess;
a pair of upper and lower guide rods supported between said side walls;
right and left line guide arms mounted slidably on said said guide and urged resiliently in opposite directions by a spring;
and
locking pins projecting from rear portions of said line guide arms, said locking pins being retractable into said line guide arms and engaging with said locking recess so that a fishing line guide portion is formed between said two line guide arms;
said locking pins being disengaged from said locking recess through said notches when said slidable member is rotated.
