US 5,494,232 A · Reversal preventive device

Abstract

A rolling member fitted into a guide recess and capable of performing a wedge action on a collar of a rotary quill is held by an annular holder in such a manner that the longitudinal movement of the rolling member can be restricted and the outside of the annular holder is rotatably fitted with an annular outer frame for restricting the outward movement of the rolling member, thereby forming a brake main body. By rotating the annular holder by use of a rotation operation member provided in the annular holder, the rolling member is controlled such that it can be restricted and held at an operative position allowing the wedge action or at a non-operative position prohibiting the wedge action, thereby switching the rotary quill to a reversal preventive position or to a reversal allowable position. Also, the brake main body is constructed as detachable one unit.

Dependent claims

A reverse rotation preventive device for selectively preventing a reverse rotation of a first member rotatably supported on a second member in a fishing reel having a reel main body and a rotor, comprising:

a modular brake unit adapted to be mounted between said first and second members such that said modular brake unit is constructed prior to assembly in said reel and is adapted for insertion and removal from said reel main body as a unitary body, said brake unit including:
a rolling member;
an annular holder integrally formed with a guide recess for accommodating and supporting said rolling member and at least one sidewall extending radially so as to restrict axial displacement of said rolling member;
first positioning means for biasing said rolling member toward a first position where said rolling member is permitted to perform a wedge action on said first member wherein said first member is permitted to rotate in a first direction and prevented from rotating in a second direction opposite to said first direction;
and
second positioning means for moving said rolling member toward a second position where said rolling member is prevented from performing said wedge action wherein said first member is permitted to rotate in both said directions.

A reverse rotation preventive device for selectively preventing a reverse rotation of a first member rotatably supported on a second member, comprising:

a brake unit adapted to be mounted between said first and second members and removable therefrom, said brake unit including:
a rolling member;
an annular holder integrally formed with a guide recess for accommodating and supporting said rolling member and two sidewalls extending radially at opposite sides of said rolling member so as to restrict axial displacement of said rolling member, said guide recess having a first opening for permitting said rolling member to contact with said first member and a second opening opposite to said first opening;
an annular outer frame coupled to said annular holder for preventing said rolling member from falling off from said annular holder through said second opening, said rolling member being permitted to contact with said annular outer frame through said second opening;
relative rotation restricting means for restricting a relative rotation of said annular holder with respect to said annular outer frame, and comprising a projection fixed with respect to one of said annular holder and said annular outer frame and a recess formed on the other of said annular holder and said annular outer frame, wherein said projection is received in said recess to prevent said relative rotation;
and
switch means for selectively switching said rolling member between a first position where said rolling member is permitted to perform a wedge action in cooperation with said first member and said annular outer frame and wherein said first member is permitted to rotate in a first direction and prevented from rotating in a second direction opposite from said first direction, and a second position where said rolling member is prevented from performing said wedge action and wherein said first member is permitted to rotate in both said directions.
