Description
BACKGROUND OF THE INVENTION
The present invention relates to a spinning reel for fishing, and more particularly relates to a spinning reel for fishing having characteristics in a fishing line guide device, for guiding a fishing line to a spool, which is rotated together with a rotor rotating in accordance with operation of a handle.
Generally, the fishing line guide device of the spinning reel for fishing is provided with a line roller for guiding the fishing line to wind the line around the spool. The line roller is generally rotatably supported through the bearings so as to improve guiding property of the fishing line, but since the line roller is a portion directly contacting with the fishing line to which much water and dusts are attached, the water and dust come into an outer periphery and an inner part of the support member supporting the line roller. In case that the water and dusts invade, rotation performance of the roller is lowered and the line winding efficiency becomes poor accordingly, and further, rusts are produced to bring about inconvenience to the line guiding function.
Therefore, for example, as disclosed in JP-A-6-15469U or JP-A-8-308444, a fishing line guide device is proposed which is treated with a waterproof for improving a smooth rotation of the line roller and preventing generation of rust.
However, the fishing line guide device mentioned above has problems as follows.
JP-A-6-15469U discloses a fishing line guide device having a sticky sealing material filled in a gap between a line roller side and a support member. However, the sticky sealing material may be mixed with water and, for example, denatured owing to use for a long period to be easily deteriorated and hardened, so that the rotating performance of the roller is lowered and becomes unstable. The sticky sealing material is removed when washing for maintenance after use, and is required to re-fill, deteriorating the maintenance, thereby being uneconomical.
JP-A-8-308444 discloses a fishing line guide device in which a bush is interposed between the outer ring of a bearing and the inside of the line roller, and an inner projection formed on the bush at one end thereof is contacted (called as “contact portion” hereafter) to a supporting member, and a seal member is provided between the inside of the opposite end of the bush and a shaft, thereby waterproofing the bearing of the line roller. In such a structure, if the bush of a hard material is used to maintain supporting precision of the line roller, it becomes difficult to secure a sufficient waterproof effect to the contacting portion, and the rotating efficiency of the line roller goes down due to force of the contacting portion. In case a bush of an elastic material is used, taking the waterproofing effect into consideration, it becomes difficult to stably support the line roller, and as a result, a bad rotation might result due to rattling play or eccentricity.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
First Embodiment
A spinning reel for fishing according to a first embodiment of the invention will be explained with reference to the attached drawings.
As shown in
FIG. 1
, the spinning reel for fishing includes a drive gear (not shown) provided in a reel main body
1
to be driven by rotation of a handle
3
. The drive gear meshes with a pinion (not shown). A spool shaft (not shown) is axially inserted through the pinion. The spool shaft includes a distal end rotatably attached to a spool
5
for winding the fishing line therearound. In this case, the spool shaft (spool) is so constituted as to be moved back and forth through an oscillating mechanism (not shown) in association with rotation of the drive gear.
The pinion has a distal end attached to a rotor
7
to be rotated together with the pinion, and the rotor
7
has a pair of support arms
9
. A bail
13
respectively is mounted on the support arms
9
through supporting members
11
. The bail
13
can be rotated between a state of leasing the fishing line and a state of winding up the fishing line and can be held in the states. A fishing line guide device
15
is supported between one of the support members
11
and the bail
13
as will be later described.
With such a the structure, when the handle
3
is rotated, the rotational movement is transmitted to the pinion through the drive gear, and the rotor
7
is rotated through the pinion while the rotational movement is transmitted to the spool through the oscillating mechanism to move the spool
5
back and forth. Thereby, the fishing line is evenly wound around the spool
5
through the fishing line guide device
15
without being partially biased.
As shown in
FIG. 2
, the fishing line guide device
15
according to the embodiment is fixedly connected to one of the support members
11
by a screw
19
, and includes a line slider
21
formed with a supporting portion
17
for the screw axially extending. The supporting portion
17
may be, as shown, formed in one body with the line slider
21
, or may be formed in one body with the supporting member
11
.
One end of the bails
13
is a base portion connected to the line slider
21
. When the bail
13
is rotated to the state of winding the fishing line to start to wind up the line on the spool, the fishing line is guided and slid from the bail
13
through the line slider
21
to the line roller
23
as a part of the composing members of the fishing line guide device
15
.
The line roller
23
is rotatably supported by the support portion
17
through one or a plurality of bearings (in the embodiment, two bearings
25
,
27
by way of one example). In this case, the line roller
23
is hollow and substantially cylindrical, having an outer periphery of smooth surface. The fishing A line guided from the bail
13
through the line slider
21
when winding, may smoothly slide on the outer peripheral surface of the line roller
23
and is wound around the spool
5
. The shape of outer periphery of the line roller
23
is not specifically limited.
The two bearings
25
,
27
are provided between the inner peripheral surface of the line roller
23
and the support portion
17
, and are arranged in parallel in the axial direction (the direction along a rotational axis A of the line roller
23
), and separately disposed each other.
The opposite ends of the two bearings
25
,
27
are contacted to a stopper portion
29
protruded from the inner periphery of the line roller
23
. The bearing
25
has an outer side end which is abutted against a stopper portion
33
formed at the support portion
17
through a first seal member
31
. On the other hand, the bearing
27
has an outer side end which is abutted against a stopper portion
37
through a second seal member
35
, the stopper portion
37
being formed at the support member
11
and covering the end portion of the support portion
17
.
In this case, the two bearings
25
,
27
are prevented from moving axially by the stoppers
29
,
33
,
37
. The first and second seal members
31
,
35
seal the part between the outer periphery of the support portion
17
and the inner periphery of the line roller
23
, and are held between the two bearings
25
,
27
and the stoppers
33
,
37
. Accordingly, the line roller
23
supported by the two bearings
25
,
27
is rotatably supported through the two bearings
25
,
27
under the condition of regulating the axial movement with respect to the support portion
17
of the support member
11
, and the respective bearings
25
,
27
are sealed through the seal members
31
,
35
.
The first and second seal members
31
,
35
may be made of materials such as nitrile rubber, urethane rubber, fluoro rubber, silicone rubber, or ethylene-propylene rubber. The shape of the seal members
31
,
37
may be assumed ring-like or circular, but in so far as the seal members have a waterproof function in the line roller
23
, the shape is not be specifically limited, but may be optional.
According to the first embodiment, the first and second seal members
31
and
35
as well as the two bearings
25
are
27
are separately arranged in the axial direction, so that it is possible to realize the fishing line guide device
15
which improves the bearing function and the waterproofing function of the line roller
23
. Therefore, the line roller
23
may maintain a smooth rotation for a long time.
Further, in addition to the above mentioned structure, the stoppers
29
,
33
,
37
are provided to engage the bearings
25
,
27
to regulate the line roller
23
in the axial movement. It is possible to prevent the first and second seal members
31
,
35
from deformation and damage, thereby to maintain the good waterproofing function for a long period of time.
Second Embodiment
Subsequently, a spinning reel for fishing according to a second embodiment of the invention will be explained with reference to FIG.
3
.
According to the embodiment as will be described below, a fishing line guide device
15
is different from that of the first embodiment and other structures are the same. Therefore, the following description will be limited to the different parts of the fishing line guide device
15
, and the same parts are indicated with the same reference numerals to omit explanation therefor.
As shown in
FIG. 3
, in the fishing line guide device
15
according to the embodiment, the first seal member
31
has a portion fitted in a peripheral groove
39
formed in the outer peripheral surface of the support portion
17
, and the second seal member
35
is in contact with a stopper
41
. In this case, the stopper
41
is formed with a member different from the support member
11
and the line slider
21
, and the stopper
41
is disposed between the line roller
23
and the support member
11
when setting up the device.
The bearing
25
is pressed toward the stopper
29
by elastic force of the first seal member
31
fitted in the peripheral groove
39
, and the pressing force is transmitted to the second seal member
35
through the bearing
27
and is held by the stopper
41
. Therefore, preferably the stopper
41
is made of a material of comparatively high rigidity such as, for example, metal, POM (Polyacetal, Polyoxymethylene) or ABS (acrylonitrile-butadiene-styrene resin).
With the structure as described above, when the fishing line guide device
15
is rotated in a direction of an arrow R when winding up the fishing line, the force is given by the fishing line through the line roller
23
in the direction of an arrow B, and this force B is held by the stopper
41
. On the other hand, in case the force is given in the opposite direction, the force is held by the first seal member
31
at a level without producing practical problem. Namely the two bearings
25
,
27
are maintained under the condition of regulating the movement in the axial direction by the first seal member
31
and the stopper
41
, while the line roller
23
supported by the two bearings
25
,
27
is held as regulated in the movement in the axial direction with respect to the support portion
17
via the bearings
25
,
27
.
Other operational effects are the same as in the first embodiment and no description is made.
Third Embodiment
Next, a spinning reel for fishing of a third embodiment of the invention will be explained with reference to FIG.
4
.
As shown in
FIG. 4
, in the fishing line guide device
15
according to the third embodiment, the first seal member
31
includes a portion fitted in a peripheral groove
43
formed in the outer peripheral surface of the line roller
23
, while the second seal member
35
has a part fitted in a peripheral groove
45
formed in the inner peripheral surface of the line roller
23
. In this case, the opposite ends of the two bearings
25
,
27
are in contact with the stopper
29
formed in the inner periphery of the line roller
23
. The outer end of the bearing
25
is in contact with the stopper
33
formed in the support portion
17
, while the outer end of the bearing
27
is in contact with the stopper
37
formed in the support member
11
in the same manner as the first embodiment.
With such a structure, since the two bearings
25
,
27
are prevented from the axial movement by the stoppers
29
,
33
,
37
, the line roller
23
supported by the two bearings
25
,
27
is prevented from the axial movement with respect to the support portion
17
by the bearings
25
,
27
.
Since the bearings are waterproofed by the first seal member
31
and the second seal member
35
respectively, the line roller
23
may maintain the smooth rotation for a long period of time.
Other operational effects are the same as in the first embodiment and no explanation will be made.
Fourth Embodiment
A spinning reel for fishing of a fourth embodiment of the invention will be explained with reference to FIG.
5
.
As shown in
FIG. 5
, in the fishing line guide device
15
according to the fourth embodiment, the line roller
23
is rotatably supported on the support portion
17
through one bearing
47
. The bearing
47
has one end being in contact with the end surface of a stopper
49
protruded from the inner periphery of the line roller
23
and being in contact with the end surface of a stopper
51
protruded from the outer periphery of the support portion
17
, and has the other end being in contact with the end surface of a stopper
53
formed at the support member
11
and covering the support portion
17
.
The first seal member
31
includes a portion fitted in a peripheral groove
55
formed at the outer periphery of the support portion
17
. The second seal member
35
is in contact with a ring like member
57
(for example, C ring or O ring) which is in engagement with a peripheral groove
59
formed in the inner periphery of the line roller
23
.
In this case, the bearing
47
is prevented from the axial movement by the stoppers
49
,
51
,
53
. The second seal member
35
is held between the bearing
47
and the ring like member
57
. Further, for the purpose of positioning the second seal member
35
to exhibit the waterproofing function, the ring-like member
57
may preferably made of a material, for example, such as stainless steel.
With such a structure, since a single bearing
47
can be prevented from the axial movement by the stoppers
49
,
51
,
53
, it is possible to realize the fishing line guide device
15
enabling to exhibit a reliable bearing function with parts of the less number.
Other operational effects are the same as in the first embodiment and no explanation will be further made.
Fifth Embodiment
A spinning reel for fishing of a fifth embodiment of the invention will be explained with reference to FIG.
6
.
As shown in
FIG. 6
, in the fishing line guide device
15
applied to the embodiment, the two bearings
25
,
27
are in contact to the respective ends of the line roller
23
through stoppers
62
,
64
, interposed between first and second collars
61
,
63
and the support portion
17
, and arranged in parallel in the axial direction, and separately disposed each other.
The two bearings
25
,
27
includes the opposite ends being in contact respectively with stopper portions
65
,
67
projected from the inner ends of the first and second collars
61
,
63
toward the center. Namely, the bearing
25
includes the outer end being in contact with the stopper
33
through the first seal member
31
and includes the opposite end being in contact with the stopper portion
65
of the first collar
61
. The bearing
27
includes the outer end being in contact with the stopper
37
through the second seal member
35
and includes the opposite end being in contact with the stopper portion
67
of the second collar
63
.
In this case, the two bearings
25
,
27
are prevented from the axial movement by the stoppers
33
,
65
,
37
,
67
. The first and second seal members
31
,
35
are held between the two bearings
25
,
27
and the stoppers
33
,
37
respectively. As a result, the line roller
23
supported by the two bearings
25
,
27
is held as regulated in the axial movement with respect to the support portion
17
via the bearings
25
,
27
.
The first and second collars
61
,
63
are preferably made of a material, for example, such as POM or ABS.
With the structure as described, it is possible to prevent the movement in the axial direction and provide the waterproof, excepting stepwise processing in the inner periphery of the line roller made of a material to be processed as metal or ceramics.
Other operational effects are the same as in the first embodiment and no explanation will be further made.
In the above described embodiments which the seal member is in direct contact with the bearing, the seal member may be so constructed that the seal member is in contact with one of an outer ring and an inner ring of the bearing and is not in contact with the other. That is, the bearing is constituted by the outer ring, the inner ring and balls, and the outer ring is rotated with respect to the inner ring through the balls. Therefore, by providing a space between the seal member and one of the outer ring and the inner, the outer ring can be smoothly rotated with respect to the inner ring. For example, the first seal member
31
in the first embodiment is in direct contact with the bearing
25
, more specifically, the inner ring of the bearing
25
is in contact with the first seal member
31
, and the outer ring of the bearing
25
is not in contact with the first seal member
31
. Therefore, the outer ring can be smoothly rotated with respect to the inner ring, thereby improving the rotation performance of the line roller. This structure can be obtained by forming a taper portion to a portion of the seal member at the inner or outer ring side.
According to the invention, it is possible to provide such a spinning reel for fishing having a fishing line guide device which improves simultaneously the bearing function and the waterproofing function of the line roller while stabilizing the rotation of the line roller.
