ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a fishing spool, more particularly to a fishing reel rotor with a one-way brake assembly which is movable between a braking position, where a fishline is prevented from unwinding from a reel rotor, and a release position, where the fishline is permitted to unwind from the reel rotor.
2. Description of the Related Art
Referring to
FIGS. 1 and 2
, a conventional fishing reel rotor is shown to include a main body
1
and a one-way brake assembly
2
. The main body
1
includes a mounting member
101
adapted to be connected to a fishing rod (not shown), a rotary lever
102
disposed rotatably on the mounting member
101
, a driving rod
103
journalled on the mounting member
101
and connected to the rotary lever
102
so as to be rotatable with the rotary lever
102
, a movable shaft
104
disposed axially and movably within the driving rod
103
, and a brake-controlling rod
105
journalled on the mounting member
101
and parallel to the movable shaft
104
. The brake assembly
2
includes an annular bearing seat
201
mounted fixedly on an end face
106
of the main body
1
by screws, an outer brake ring
202
mounted fixedly within the bearing seat
201
, a roller-positioning member
203
mounted rotatably within the outer brake ring
202
, a plurality of rollers
204
disposed in the roller-positioning member
203
, an inner brake tube
205
sleeved non-rotatably on the driving rod
103
and disposed within the bearing seat
201
and adjacent to the rollers
204
, a plurality of torsion springs
206
disposed between the rollers
204
and the bearing seat
201
, a driving ring
207
linked to the roller-positioning member
203
in the bearing seat
201
and connected operably to the brake-controlling rod
105
, and a cover
208
that confines the outer brake ring
202
, the rollers
204
, the roller-positioning member
203
, the inner brake tube
205
, and the driving ring
207
within the bearing seat
201
. The outer brake ring
202
has an inner surface formed with a plurality of grooves
209
that are arranged in a circumferential direction. Each of the grooves
209
has a shallow groove portion
209
′ and a deep groove portion
209
″.
When the brake-controlling rod
105
is manipulated, the driving ring
207
will bring the roller-positioning member
203
and the rollers
204
to rotate within the outer brake ring
202
so that the rollers
204
displace along the grooves
209
between the shallow and deep groove portions
209
′,
209
″. When the rollers
204
are located in the shallow groove portions
209
′, the inner brake tube
205
and the driving rod
103
can rotate in the roller-positioning member
203
in a single direction so as to prevent unwinding of a fishline from the spool. When the rollers
204
are located in the deep groove portions
209
″, the inner brake tube
205
and the driving rod
103
can rotate in the roller-positioning member
203
in two directions so as to permit winding and unwinding of the fishline with respect to the spool. The rollers
204
are biased by the torsion springs
206
into the shallow groove portions
209
′.
However, the above-described fishing reel rotor suffers from the following drawbacks:
1. As a plurality of torsion springs
206
are required, and as the wire diameter of the torsion springs
206
is relatively small, assembly is not convenient.
2. Since the brake assembly
2
includes a relatively large number of components, and since the bearing seat
201
is fastened to the main body
1
by screws, a lot of assembly steps will be involved, and there may be cumulative tolerances of the components, so that the concentricity of the components cannot be preserved, thereby resulting in undesirable noise.
3. In addition, the screws may loosen after a period of use, and may thus affect the structural strength of the fishing reel rotor.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a fishing reel rotor with a one-way brake assembly, which is relatively simple in construction, which can enhance structural strength, and which can preserve concentricity of the components.
Accordingly, a fishing reel rotor of the present invention is adapted to be connected removably to a fishing rod, and comprises:
a main body including
a mounting member adapted to be connected removably to the fishing rod,
a rotary lever disposed rotatably on the mounting member,
a hollow driving rod journalled on the mounting member and connected to the rotary lever, the driving rod being rotatable on the mounting member when the rotary lever rotates,
a movable shaft disposed axially and movably within the driving rod,
an annular bearing seat connected fixedly to the mounting member and disposed around the driving rod, and
a brake-controlling rod journalled on the mounting member and parallel to the driving rod, the brake-controlling rod being rotatable between a braking position and a release position;
a roller-positioning member having a ring plate that is mounted rotatably within the bearing seat and that is disposed around the driving rod, the ring plate having a side surface that is formed with a plurality of positioning blocks that project integrally and axially therefrom and that are arranged along a circle, each adjacent pair of the positioning blocks defining a roller-receiving space therebetween;
an outer brake ring mounted fixedly within the bearing seat and disposed around the positioning blocks of the roller-positioning member, the outer brake ring having an inner surface which is formed with a plurality of grooves that are arranged along a circumferential direction, each of the grooves having a shallow groove portion and a deep groove portion that is deeper than the shallow groove portion;
a plurality of rollers disposed respectively and movably within the roller-receiving spaces in the roller-positioning member;
an inner brake tube sleeved non-rotatably on the driving rod so as to rotate synchronously therewith, the inner brake tube being disposed within the roller-positioning member and having an outer surface that is adjacent to the rollers;
an annular driving ring disposed rotatably around the driving rod and within the bearing seat and connected non-rotatably to the roller-positioning member, the driving ring being connected operably to the brake-controlling rod and rotatable between a first position, where the brake-controlling rod is disposed at the release position and where the rollers are located within the deep groove portions of the grooves so as to permit bi-directional rotation of the driving rod and the inner brake tube within the roller-positioning member, and a second position, where the brake-controlling rod is disposed at the braking position and where the rollers are located within the shallow groove portions of the grooves, thereby permitting unidirectional rotation of the driving rod and the inner brake tube within the roller-positioning member;
an annular cover disposed around the driving rod and connected fixedly to the bearing seat so as to confine the roller-positioning member, the outer brake ring, the rollers, the inner brake tube, and the driving ring within the bearing seat; and
a coiled tension spring having two ends that are fastened respectively to the cover and the driving ring, the tension spring being stretched when the driving ring is disposed at the first position so as to create a restoration force for biasing the driving ring to the second position.
Because only one spring, i.e., the tension spring, is incorporated in the fishing reel rotor, the structure of the fishing reel rotor is relatively simple.
Preferably, the bearing seat is formed integrally with the mounting member to enhance structural strength of the fishing reel rotor and to preserve concentricity of the components.
