ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a spinning reel, particularly for a fishing reel, provided with a mechanism smoothly movable or slidable in an axial direction of a spool shaft.
In general, there is widely known a spinning reel for winding up a fishing line by rotating a rotational frame of the reel and moving a spool reciprocally in a rotation axis direction of the rotational frame.
FIG. 53
shows one example of a conventional spinning reel, in which reference numeral
201
denotes a body casing, i.e. reel body, and a handle shaft
202
is mounted to the body casing
201
to be rotatable. A coupling gear
203
is secured to the handle shaft
202
, and the coupling gear
203
is engaged with an oscillator gear
204
rotatably mounted to the body casing
201
. A pin
205
engaged with a slot
206
a
formed to an oscillator
206
is provided for the oscillator gear
204
. Secured to the oscillator
206
is a spool shaft
208
having a front end to which a spool
208
is mounted.
When the spinning reel of the structure described above is operated by gripping and rotating a handle lever
209
to rotate the handle shaft
202
, the coupling gear
203
mounted to the handle shaft
202
is also rotated, thus the oscillator gear
204
being rotated, thereby moving the pin
205
along the slot
206
a.
In this manner, the oscillator
206
and, hence, the spool shaft
207
is moved reciprocally in a longitudinal direction, i.e. bilateral direction in FIG.
53
.
However, according to the above prior art structure, the spool shaft does not perform a uniform reciprocal motion and, under such state, when the fishing line is wound up, the fishing line is not uniformly wound up around the spool and will be relaxed as shown in FIG.
54
.
In order to obviate such defect, a prior art further provides a structure for making almost uniform the reciprocal motion of the spool shaft such as disclosed in the Japanese Patent Publication No. HEI 2-60295.
FIG. 55
shows a structure of a spinning reel of this publication, in which reference numeral
301
denotes a body casing to which a handle shaft
302
is mounted to be rotatable. Secured to the handle shaft
302
is a coupling gear
303
which is engaged with an oscillator gear
304
mounted to the body casing
301
to be rotatable. The oscillator gear
304
is formed with a slot
304
a
extending in the radial direction thereof, and a follow-up pin
305
penetrates the slot
304
a.
The follow-up pin
305
has one end engaged with a cam groove
301
a
formed to the body casing
301
and has another one end engaged with a slot
306
a
of an oscillator
306
. A spool
308
is mounted to one end of a spool shaft
307
. The cam groove
301
a
as a shape enabling the spool
308
to perform almost uniform motion.
When the handle shaft
302
is driven and rotated by a handle lever
309
, the coupling gear
303
is rotated and hence the oscillator gear
304
is also rotated. Upon the rotation of the oscillator gear
304
, the follow-up pin
305
penetrating the slot
304
a
moves along the cam groove
301
a
and the slot
306
a.
In this manner, the oscillator
306
and the spool
308
is moved reciprocally in the bilateral direction as viewed in
FIG. 54
at substantially the uniform motion speed.
Furthermore, it has been considered that a clearance having a proper gap is made between the follow-up pin
305
and the cam groove
301
a.
However, even in the above structure, there is provided the following problems. That is, according to the above structure, since the follow-up pin
305
inclines during its movement, the spool is not moved smoothly. The inclining motion of the follow-up pin
305
will cause wearing of the slots, the cam groove and the follow-up pin itself, thus being not advantageous. Furthermore, when an impact is applied in the spool axis direction by a falling down shock of the spinning reel, for example, the slots, the cam groove and the follow-up pin will easily damaged, also providing a problem. The inclining motion of the follow-up pin
305
will not cause a smooth rotation of the rotational frame of the spinning reel. Still furthermore, since the follow pin
305
has to be disposed inside tooth bottom of the oscillator gear
306
, it is difficult to make large strokes of the oscillator and the spool.
In the arrangement provided with the clearance mentioned above, the axial movement of the spool shaft is not stable, and an undesired backlash may be caused during the movement between the spool and the reel body, also providing a problem.
SUMMARY OF THE INVENTION
An object of the present invention is to substantially eliminate defects or drawbacks encountered in the prior art described above and to provide a spinning reel, particularly for fishing, capable of performing a uniform and smooth motion of a spool of the spinning reel in its longitudinal direction and being improved in its durability.
This and other objects can be achieved according to the present invention by providing, in one aspect, a spinning reel comprising:
a reel body casing;
a rotational frame member rotatably provided for the reel body casing;
a spool shaft provided for the reel body casing to be movable in a rotation axis direction of the rotational frame member;
a spool mounted to one end portion of the spool shaft;
a handle means operatively connected to the rotational frame member capable of rotating the same;
an oscillator means secured to another end portion of the spool shaft;
an oscillator gear provided for the reel body casing to be rotatable by the handle means; and
a rotational member mounted to the oscillator gear to be rotatable,
the rotational member being formed with a first projection engageable with a cam groove formed to an inner surface of the reel body casing and a second projection engageable with the oscillator means.
In preferred examples in this aspect, the first and second projections are formed on opposing surfaces of the rotational member, respectively, shifted in angles from each other.
The oscillator means is provided with a slot with which the second projection is engageable. The oscillator gear and the rotational member is operatively connected through a link mechanism. The oscillator gear is mounted to an oscillator gear shaft secured to the reel body casing, the oscillator gear shaft being provided with a flanged portion in a direction perpendicular to an axial direction of the oscillator gear shaft.
The rotational member is provided with a body portion and a flanged portion, and the first projection is formed to and flanged portion. The flanged portion is engageable with a recessed portion formed to the oscillator gear. A plate member is secured to the rotational member for preventing the rotational member from falling down from the oscillator gear. The plate member may be secured to the oscillator gear for preventing the rotational member from falling down from the oscillator gear.
A plate member having a diameter larger than that of the body portion of the rotational member is secured thereto and the plate member is positioned in the recessed portion of the oscillator gear.
A reel body casing is integrally formed with a boss portion to which the oscillator gear is rotatably mounted and a metallic pin is fitted to the boss portion, and the reel casing body is formed of a resin material.
At least one of the first and second projections has a portion positioned outwardly apart from a tooth bottom circle of the oscillator gear.
In another aspect of the present invention, there is provided a spinning reel comprising:
a reel body casing;
a rotational frame member rotatably provided for the reel body casing;
a spool shaft provided for the reel body casing to be movable in a rotation axis direction of the rotational frame member;
a spool mounted to one end portion of the spool shaft;
a handle means operatively connected to the rotational frame member capable of rotating the same;
an oscillator means secured to another end portion of the spool shaft;
an oscillator gear provided for the reel body casing to be rotata
