ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a change-speed construction, more particularly to a change-speed construction for a fishing reel that is provided with an easy-to-operate change-speed knob.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional change-speed construction for a fishing reel is shown to include a reel body
10
, a rotary arm
12
, a T-shaped handle unit
13
, a hollow housing
21
, a spring-biased control shaft
14
, a spring member
221
, and a retaining member
20
.
As illustrated, the rotary arm
12
has an inner end mounted rotatably on a side plate
11
of the reel body
10
. The handle unit
13
is disposed on an outer end of the rotary arm
12
. The housing
21
is fixed on the inner end of the rotary arm
12
. The control shaft
14
is mounted on the inner end of the rotary arm
12
and extends axially and movably on the reel body
10
in a manner, as disclosed in U.S. Pat. No. 5,058,447. The control shaft
14
is biased to an extended position, where the reel is adapted to rotate at a first speed. The control shaft
14
is capable of being pushed axially and inwardly to a retracted position relative to the reel body
10
, where the reel is adapted to rotate at a second speed. The control shaft
14
extends through the housing
21
, and has an annular groove
141
formed therein. The spring member
221
is disposed within the housing
21
, and includes an elongated retaining plate
22
that has an inner end
222
disposed operably in the housing
21
, and a push knob
224
mounted fixedly on an outer end of the retaining plate
22
in such a manner that the push knob
224
is exposed outwardly from the housing
21
. The retaining plate
22
further has a shaft engaging hole
223
, through which the control shaft
14
extends. When the control shaft
14
is pushed inwardly and axially in a direction denoted by arrowhead R
1
in
FIGS. 3A and 3B
, the retaining plate
22
is biased in a direction denoted by arrowhead R
2
to engage the annular groove
141
in the control shaft
14
, thereby retaining the control shaft
14
at the retracted position.
Referring to
FIGS. 2A and 2B
, upon actuation of the push knob
224
in a direction denoted by arrowhead R
4
, the retaining plate
22
disengages the annular groove
141
in the control shaft
14
against biasing action of the spring member
221
to permit movement of the control shaft
14
in a directed denoted by arrowhead R
3
so as to restore the control shaft
14
to the extended position.
Note that in order to permit movement of the control shaft
14
from the retracted position of
FIGS. 3A and 3B
to the extended position shown in FIGS.
2
A and
2
B, the push knob
224
must be depressed in the direction denoted by the arrowhead R
4
in
FIGS. 2A and 2B
against biasing action of the spring member
221
. It is relatively difficult for the user to depress the push knob
224
while the user is holding the handle unit
13
for winding and unwinding of the reel.
SUMMARY OF THE INVENTION
Therefore, the object of this invention is to provide a change-speed construction for a fishing reel that includes an easy-to-operate change-speed knob that can be operated while winding and unwinding the reel.
Accordingly, a change-speed construction for a fishing reel comprises a reel body, a rotary arm, a T-shaped handle unit, a tubular hollow housing, a spring-biased control shaft, a pivot member, a retaining member, and a spring member. The rotary arm has an inner end mounted rotatably on the reel body, and an outer end. The T-shaped handle unit is disposed on the outer end of the rotary arm, and the tubular hollow housing is fixed on the inner end of the rotary arm. The spring-biased control shaft is mounted axially and movably on the reel body and biased to an extended position, and is capable of being pushed axially and inwardly to a retracted position. The control shaft extends through the housing, and has annular groove formed therein. The pivot member is disposed in the housing and parallel to the control shaft. The retaining member includes an elongated retaining plate having an inner end rotatably connected to the pivot member, and an outer end, and a push knob connected fixedly to the outer end of the retaining plate and exposed outwardly from the housing. The retaining member is disposed relative to the control shaft so that the retaining plate engages the annular groove in the control shaft upon rotation of the retaining member. Finally, the spring member is provided to bias the retaining member so that the retaining plate engages the annular groove in the control shaft when the control shaft is disposed at the retracted position so as to retain the control shaft at the retracted position. The push knob of the retaining member is capable of being pushed in the direction, when the control shaft is disposed at the retracted position, against biasing action of the spring member so as to disengage the retaining plate from the annular groove such that the control shaft is biased to move from the retracted position to the extended position.
