Abstract
A brake system for use in a fishing reel of the type having a housing and a spool mounted for rotation relative to the housing about an axis. The brake system consists of a brake surface on the housing, a brake arm having a brake pad, with a brake surface press fit structure for retaining the brake arm in operative position on the spool for rotation therewith, and structure mounting the brake pad on the brake arm so that the brake surface on the brake pad moves biasably against the housing brake surface under a predetermined centrifugal force developed through rotation of the spool.
Claims14
A centrifugal brake system for a line-carrying spool on a fishing reel of the type having a housing and means for supporting the spool on the housing for rotation relative to the housing about an axis, said brake system comprising:
- a brake surface on said housing;
- a brake arm having a brake pad;
- press fit means for retaining the brake arm in operative position on the spool for rotation therewith;
- a brake surface on the brake pad;
- and
- means mounting the brake pad on the brake arm for movement of the brake surface on the brake pad biasably against the housing brake surface under a predetermined centrifugal force developed through rotation of the spool,
- wherein said spool has a shaft and said retaining means comprises a ring with a bore to closely frictionally accept the spool shaft,
- wherein said spool has an axially facing surface, the ring is mounted for translatory axial movement relative to the spool shaft between a release position wherein the brake arm can be placed in and removed from operative position on the spool and a retention position, said ring has a first surface and with the ring in the retention position the brake arm is captively retained between the first ring surface and spool surface.
A centrifugal brake system for a line-carrying spool on a fishing reel of the type having a housing and means for supporting the spool on the housing for rotation relative to the housing about an axis, said brake system comprising:
- an annular radially inwardly facing brake surface on said housing;
- a brake arm;
- press fit means separate from and movable relative to said brake arm for retaining the brake arm in operative position on the spool for rotation therewith;
- a brake pad with a brake surface;
- means mounting the brake pad on the brake arm with the brake pad surface facing the housing brake surface for translatory radial movement relative to the brake arm between (a) a brake position wherein the brake pad surface is biased against the brake surface on the housing with a predetermined force by centrifugal force on said brake pad developed through rotation of the spool at a predetermined speed and (b) a release position wherein the brake pad surface is biased against the brake surface on the housing with less than said predetermined force with the spool rotating at leass than said predetermined speed wherein said brake arm comprises a formed piece of wire having a curved portion which seats against the spool shaft with the support arm in operative position on the spool.
A centrifugal brake system for a line-carrying spool on a fishing reel of the type having a housing and means for supporting the spool on the housing for rotation relative to the housing about an axis, said brake system comprising:
- an annular radially inwardly facing brake surface on said housing;
- a brake arm;
- press fit means for retaining the brake arm in operative position on the spool for rotation therewith;
- a brake pad with a brake surface;
- means mounting the brake pad on the brake arm with the brake pad surface facing the housing brake surface for translatory radial movement relative to the brake arm between (a) a brake position wherein the brake pad surface is biased against the brake surface on the housing with a predetermined force by centrifugal force on said brake pad developed through rotation of the spool at a predetermined speed and (b) a release position wherein the brake pad surface is biased against the brake surface on the housing with less than said predetermined force with the spool rotating at less than said predetermined speed,
- wherein said spool has a shaft and the retaining means comprises a ring with a through bore to closely accept the spool shaft to permit sliding movement of the ring axially of the shaft,
- wherein the spool has an axially facing surface, said ring has first and second annular, substantially parallel flat surfaces and said retaining means includes means mounting the ring for translatory movement relative to the spool shaft between (a) a release position wherein the brake arm can be placed in and removed from operative position on the spool and (b) a retention position wherein said brake arm is held captive between the spool surface and the first surface, said second surface residing axially closer to the spool surface than the second surface with the ring in the retention position.
