Description
BACKGOURND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fishing spinning reel in which an opposite member such as a spool or a reel body in which a drag braking mechanism is housed is made waterproof.
2. Description of the Related Art
A spool of a related fishing spinning reel includes: a through-hole into which a spool shaft is inserted, formed at the center of the spool; a recess for housing a drag braking mechanism, formed on the front side of the spool; and a drag braking knob screwed to the spool shaft inserted into the through-hole.
Due to the above arrangement, water enters the spool from the front and the rear side, and the drag braking mechanism is corroded. For the above reasons, it is impossible to obtain a stable drag performance, and problems tend to occur in its operation.
In order to solve the above problems caused by intrusion of water, for embodiment, as disclosed in Japanese Unexamined Utility Model Unexamined Publication Nos. 3-67562 and 3-91776, proposals are made in which waterproof treatment is conducted between the spool and the drag braking knob.
However, in the structure disclosed in the former utility model publication, the following problems may be encountered. The annular protrusion for preventing the intrusion of water is formed integrally with the member for holding the drag braking mechanism. Therefore, the annular protrusion for preventing the intrusion of water is made of hard material. Accordingly, it is impossible to provide a waterproof effect, and further it-becomes difficult to adjust a drag braking force.
In the structure disclosed in the latter utility model publication, the following problems may be encountered. When dust or sand enters the circumferential grooves of the elastic seal, it becomes difficult for the contact surface to uniformly come into contact with the elastic seal in the case where the elastic seal is pushed in the process of drag braking control. As a result, gap may be caused between the seal and the contact surface.
In the structures of both the former and the latter utility model publications, when the reel is dipped in water, water enters the spool from the rear side thereof.
SUMMARY OF THE INVENTION
In view of the above problems, an object of the present invention is to provide a fishing spinning reel, with a stable drag performance which water is prevented from entering the opposite member in which the drag braking mechanism is housed so that the occurrence of inferior operation can be prevented.
In order to solve the above problems, there is provided a fishing spinning reel including: a drag braking knob imparting a drag braking force to a spool, an opposite member opposite to the drag braking knob, a sliding contact section for waterproof arranged in one of the drag braking knob and the opposite member, and a sliding contact member for waterproof arranged in the other of the drag braking knob and the opposite member. The sliding contact member for waterproof includes a contact portion being elastically deformable and slidably contactable with a sliding surface of the sliding contact section for waterproof.
Further, according to the present invention, there is provided a fishing spinning reel including: a drag braking mechanism imparting a drag braking force to a spool, the drag braking mechanism having a drag braking knob being rotatable; an opposite member opposite to the drag braking knob so as to receive the drag braking mechanism between the opposite member and the drag braking knob; a first sliding contact section for waterproof arranged in one of the drag braking knob and the opposite member; and a first sliding contact member for waterproof arranged in the other of the drag braking knob and the opposite member, the first sliding contact member for waterproof including a first contact portion elastically deformable and slidably contactable with a first sliding surface of the first sliding contact section for waterproof; a second sliding contact member for waterproof arranged around a spool shaft on an opposite side to the drag braking knob with respect to the opposite member, the second sliding contact member having a second contact portion; a second sliding contact section for waterproof opposing to the second sliding contact member for waterproof, the second sliding contact section defining a sliding surface to be contacted with the second contact portion of the second sliding contact member, whereby the drag braking mechanism arranged in the opposite member is made waterproof in the axial direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to embodiments shown in the drawings, the present invention will be explained below.
[First Embodiment]
FIGS. 1 to 3 are views showing the first embodiment. FIG. 1 is a cross-sectional side view of a fishing spinning reel, FIG. 2 is a cross-sectional side view showing a primary portion of an opposite member composed of a spool, FIG. 3A is a perspective view of a sliding contact member for waterproof arranged on the front side, and 3B is a perspective view of another sliding contact member for waterproof arranged on the rear side.
The first embodiment is a front drag type fishing spinning reel. The opposite member 1 composed of a spool includes: a deep recess 1a located at the center of the front portion; a shallow recess 1b used for attaching a sliding contact member for waterproof 2A arranged forwardly and outside the front recess 1a; a through-hole 1c formed at the center; a fishing line winding drum section 1d, on the outer circumference of which a fishing line 10 is wound; a flange section 1e formed on the front side; a cylindrical section 1f of a large diameter on the rear side; a shaft cylinder section 1g arranged inside on the rear side; and a sliding contact section 1h for waterproof composed of a recess in the periphery on the outside of the shaft cylinder section 1g.
In the recess 1a, there are formed two grooves 1i in the axial direction, and also there is formed an engaging circumferential groove 1j, which is composed of a recess, in the circumferential direction of the inner circumference on the front side in the recess 1a, wherein this engaging circumferential groove 1j is formed from the inner circumference to the outside in the radial direction.
In the recess 1a, there are provided friction plates 11 and braking plates 12, 13 of drag braking mechanism A, which are prevented from coming out by a stop ring 14 engaged with an engaging circumferential groove 1j.
Protrusions formed on the outer circumference of the braking plate 12 are engaged with the two grooves 1i, so that the braking plate 12 can not be rotated.
The sliding contact member for waterproof 2A on the front side is constructed by a ring-shaped body 2a made of rubber or soft synthetic resin, and an elastic sliding contact section 2b. The sliding contact section 2b is constructed by a cylindrical section 2c and a flange section 2d protruding from the cylindrical section 2c to the outside in the radial direction.
The main body 2a is engaged with and fixed to the shallow recess 1b.
The spool shaft 3 inserted into the central through-hole 1c of the opposite member 1 composed of the spool includes: a large diameter section 3a; a small diameter section 3c arranged on the forward end side of the large diameter section 3a via a step section 3b; a rotation locking section 3d arranged on the outer circumference of the small diameter section 3c; and a screw section 3e arranged at the forward end of the small diameter section 3c.
The front side small diameter section 3c of the spool shaft 3 is inserted into the through-hole 1c.
The friction plates 11 and the braking plates 12, 13 of drag braking mechanism A are engaged with the outer circumference of the small diameter section 3c in the recess 1a, and the braking plate 13 is locked by the rotation locking section 3d.
The nut 15 embedded in the drag braking knob 4 is screwed to the screw section 3e arranged at the forward end of the small diameter section 3c.
Drag braking mechanism A includes: a friction plate 11; braking plates 12, 13; the friction plate 11 arranged on the front side of the front side braking plate 12; a pushing plate 16 arranged on the front side of the friction plate 11; and a coil-shaped spring 17 arranged in the drag braking knob 4.
The drag braking knob 4 is structured as follows. The nut 15 is embedded at the center of the drag braking knob 4. Outside the nut 15, there is provided a cylindrical section 4a. Outside the cylindrical section 4a, there is provided a sliding contact section for waterproof 4b composed of a recess.
It is possible to insert the pushing plate 16 into the inner circumference of the cylindrical section 4a. The coil-shaped spring 17 is inserted between the outer circumference of the nut 15 and the inner circumference of the cylindrical section 4a.
The sliding contact section 2b of the front side sliding contact member 2A for waterproof is inserted into the packed or sliding contact section 4b for waterproof composed of the recess. The flange section 2d slidably comes into contact with the outside sliding surface "a" in the sliding contact section 4b for waterproof composed of the recess.
In the opening of the sliding surface "a", there is provided a flange-shaped circumferential wall "a'" of small diameter which protrudes inward in the radial direction.
The spacer 18, another sliding contact member for waterproof 2B on the rear side and the click gear 19 are engaged with the outer circumference of the small diameter section 3c of the spool shaft 3 on the rear side of the shaft cylinder section 1g of the opposite member 1 composed of the spool. The spacer 18, another sliding contact member for waterproof 2B on the rear side and the click gear 19 are interposed between the shaft cylinder section 1g and the step section 3b.
Another sliding contact member for waterproof 2B on the rear side is composed of a disk-shaped body 2e and an elastic sliding contact section 2f. The sliding contact section 2f is constructed by a cylindrical section 2g and a flange section 2h protruding inward from the cylindrical section 2g in the radial direction.
The flange section 2h slidably comes into contact with the sliding surface "b" inside the sliding contact section for waterproof 1h composed of a recess on the outer circumference of the shaft cylinder section 1g.
As described above, the elastic sliding contact sections 2b, 2f are arranged in the sliding contact sections for waterproof 2A, 2B located on the front and the rear side, and further the flange sections 2d, 2h protruding in the radial direction of the sliding contact sections 4b, 1h for waterproof are arranged in the sliding contact sections 2b, 2f, so that they can slidably come into contact with the sliding surfaces "a", "b". Therefore, even if the flange sections 2d, 2h and the sliding surfaces "a", "b" are relatively moved from each other, waterproof can be positively accomplished.
Further, even if dust or sand is attached to the sliding contact sections for waterproof 4b, 1h composed of a recess, dust or sand can be scraped off by the flange sections 2d, 2h protruding in the radial directions when the flange sections 2d, 2h are moved. Accordingly, there is no possibility that the flange sections 2d, 2h are separated from the sliding surfaces "a", "b". Therefore, waterproof can be positively accomplished.
As described above, the flange section 2d of the sliding contact member 2A for waterproof on the front side slidably comes into contact with the sliding surface "a" of the sliding contact section 4b for waterproof outside the cylindrical section 4a, composed of a recess. Further, the flange section 2h of another sliding contact member 2B for waterproof on the rear side slidably comes into contact with the sliding surface "b" of the sliding contact section 1h for waterproof composed of the recess on the outer circumference of the shaft cylinder section 1g. Due to the above arrangement, even if the reel is dipped in water, it is possible to prevent water from entering the recess 1a of the opposite member 1 composed of the spool and also it is possible to prevent water from entering the through-hole 1c.
When the flange-shaped circumferential wall "a'" of small diameter, which protrudes inwardly in the radial direction, is formed into the opening of the sliding surface "a", it is possible to positively prevent foreign objects from entering inside.
The spool shaft 3 protrudes from the front side of the reel body 5.
In both side walls of the reel body 5, a rotary shaft 20a of a drive gear 20 is supported by bearings (not shown). A handle shaft 22 to which a handle 21 is fixed is detachably engaged with a central polygonal hole of the rotary shaft 20a, wherein the handle shaft 22 can be freely alternate on either side of the rotary shaft 20a.
At the front of the reel body 5, a rotary shaft cylinder 24 is pivotally supported by a bearing 23 and protruded to the front side.
A backstop ratchet wheel 25 and the rotor 6 are fixed onto the outer circumference of the rotary shaft cylinder 24 on the front side of the bearing 23 by a nut 26, wherein the backstop ratchet wheel 25 and the rotor 6 are engaged and locked so that they can not be rotated.
The base end of the rotary shaft cylinder 24 is pivotally supported by the bearing section 5a, and the drive gear 20 is meshed with a pinion 24a integrally formed on the front side of the base end. The rotor 6 is supported in such a manner that it can be rotated being linked with the rotation of the handle 21.
The large diameter section 3a of the spool shaft 3, at the forward end of which the opposite member 1 composed of the spool is attached, is slidably inserted into the central hole of the rotary shaft cylinder 24 in such a manner that the spool shaft 3 can be reciprocated in the longitudinal direction. A sliding piece 27 is attached to the rear end section 3f of the spool shaft 3 via an engaging plate 28.
An interlocking gear 29 is engaged with the rotary shaft cylinder 24 on the front side of the pinion 24a of the rotary shaft cylinder 24 in the reel body 5, wherein the interlocking gear 29 is locked so that it can not be rotated.
In the reel body 5, there is provided a traverse cam shaft 30 which is a sliding mechanism arranged in parallel to the spool shaft 3. In this case, the traverse cam shaft 30 is supported in such a manner that it is inserted into the bearing section 5a and the hole 7a of the support member 7 which is attached to the rear side of the reel body 5 by a screw 31.
On the rear side of the support member 7, there is formed a screw cylinder 7b to which a cap 32 is screwed.
At the forward end of the traverse cam shaft 30, there is provided a pinion 33 which is locked so that it can not be rotated. The pinion 33 is meshed with the above interlocking gear 29.
The sliding piece 27 is engaged with the traverse cam shaft 30, and a claw of an engagement portion 34 arranged in the sliding piece 27 is engaged with the traverse cam groove.
A backstop claw 35 faces the backstop ratchet wheel 25 in such a manner that the backstop claw 35 can be freely engaged with and disengaged from the backstop ratchet wheel 25.
On the front side of an operation rod 36 which is pivotally attached to the reel body 5, there is provided a backstop cam 37. At the operating rod 36 which protrudes outside from the rear side of the reel body 5, there is provided an operating knob 38.
The rotor 6 is attached to the rotary shaft cylinder 24 by a cylindrical section 6a. The rotor 6 includes: the cylindrical section 6a; a front wall 6b, a cylindrical section 6c of large diameter; and a pair of support arms 6f, 6g protruding to the front from the outer circumferences of the base sections 6d, 6e of the cylindrical section 6c of large diameter.
Outside the forward end portions of a pair of bail supporting arms 6f, 6g, there are provided one bail supporting member 39 and the other bail supporting member 40 which are supported by screws 41, 42 in such a manner that they can be freely inverted between the fishing line winding position and the fishing line discharging position
An attaching section 44 of a fishing line guide roller 43 is attached to one bail supporting member 39.
A bail 45 is attached between the other bail supporting member 40 and the attaching section 44 of the fishing line guide roller 43.
In one bail supporting arm 6f, there is provided a torsion spring 46. One end thereof is received within the supporting arm 6f, and the other end is engaged with the bail supporting member 39. Therefore, one bail supporting member 39, the other bail supporting member 40, the attaching section 44 of the fishing line guide roller 43 and the bail 45 are put into the fishing line winding position and the fishing line discharging position by the energizing action of the torsion spring 46. The torsion spring 46 is covered with a cover 48 which is fixed by a screw 47.
In the other bail supporting arm 6g, there is provided an L-shaped inverting function lever 49 by which one bail supporting member 39, the other bail supporting member 40, the attaching section 44 of the fishing line guide roller 48 and the bail 45 are inverted from the fishing line discharging position to the fishing line winding position.
In the bail supporting arm 6g, the inverting function lever 49 is covered with a cover 51 which is fixed by a screw 50.
One end of the inverting function lever 49 is inserted into the hole 40a of the bail supporting member 40, and the other end 49a of the inverting function lever 49 is inserted into the hole 6h formed downward in the base section 6e.
The other end 49a of the inverting function lever 49 faces the cam 5b arranged in the reel body 5 in such a manner that the inverting function lever 49 can be contacted with the cam 5b.
When the drag braking force is adjusted, the drag braking knob 4 is rotated. Then, the coil-shaped spring 17 is compressed by the nut 15. Therefore, drag braking mechanism A arranged in the recess 1a is pressed, so that the drag braking force can be adjusted.
When the drag braking knob 4 is rotated and advanced at this time, the cylindrical section 4a is advanced while the flange section 2d of the sliding contact member for waterproof 2A on the front side slidably comes into contact with the sliding surface "a" of the sliding contact section for waterproof 4b composed of the recess outside the cylindrical section 4a.
When the opposite member 1 composed of the spool is rotated by a tension of the fishing line 10 against the drag braking force, while the flange section 2d of the sliding contact member for waterproof 2A on the front side is slidably coming into contact with the sliding surface "a" of the sliding contact section for waterproof 4b composed of the recess outside the cylindrical section 4a, and while the flange section 2h of another sliding contact member for waterproof 2B on the rear side is slidably coming into contact with the sliding surface "b" inside the sliding contact section for waterproof 1h composed of the recess on the outer circumference of the shaft cylinder section 1g, the opposite member 1 composed of the spool is rotated.
The above fishing spinning reel operates as follows. In the condition that one bail supporting member 39 and the other bail supporting member 40 are set at the fishing line winding positions, when the handle 21 is rotated in a direction in which the fishing line 10 can be wound round the opposite member 1 composed of the spool, the drive gear 20 is rotated, and the rotary shaft cylinder 24 and the rotor 6 are normally rotated via the pinion 24a.
Further, the traverse cam shaft 30 is interlockingly rotated via the interlocking gear 29 and the pinion 33. Due to the foregoing, the sliding piece 27, the spool shaft 3 and the opposite member 1 composed of the spool are reciprocated in the longitudinal direction.
In the case where the rotor 6 is prevented from rotating reversely, the operating knob 38, the operating rod 36 and the backstop claw 35 are rotated, and the backstop claw 35 is engaged with the backstop ratchet wheel 25.
When the reverse rotation of the rotor 6 is prevented and fishing is conducted and also when the opposite member 1 composed of the spool is reversely rotated while the fishing line 10 is being pulled by the drag of fish, a drag braking force acts between the opposite member 1 composed of the spool and the spool shaft 3.
When the tackle is cast and the fishing line 10 is discharged to a distant position, the bail support members 39, 40 are inverted to the fishing line discharging position and the fishing rod is swung energetically.
When the bail support members 39, 40 are inverted to the fishing line discharging position, the other end 49a of the inverting function lever 49 is advanced.
When the other end 49a of the inverting function lever 49 is advanced, it faces a contact position with the cam 5b arranged in the reel body 5.
When the handle 21 is rotated in a direction so that the fishing line 10 can be rotated round the opposite member 1 composed of the spool after the tackle has been cast, the drive gear 20 is rotated, and the rotary shaft cylinder 24 and the rotor 6 are normally rotated via the pinion 24a.
When the rotor 6 is normally rotated, the other end 49a of the inverting function lever 49 comes into pressure contact with the cam 5b of the reel body 5 and is pushed backward, and the bail supporting members 39, 40 are automatically inverted into the fishing line winding position.
When the fishing spinning reel is structured as described above, even if dust or sand is attached to the sliding contact members for waterproof 2A, 2B, there is no possibility that the sliding contact sections 2b, 2f are separated from the sliding surfaces "a", "b". Accordingly, waterproof can be positively accomplished.
The elastic sliding contact sections 2b, 2f are provided in the front 2A and the rear sliding contact member 2B for waterproof. In the elastic sliding contact sections 2b, 2f, the flange sections 2d, 2h which protrude in the radial directions of the sliding contact sections 4b, 1h for waterproof composed of recesses are provided. The flange sections 2d, 2h are slidably contacted with the sliding surfaces "a", "b". Therefore, even if the flange sections 2d, 2h and the sliding surfaces "a", "b" are relatively moved, waterproof can be positively accomplished.
Therefore, even if dust or sand is attached to the sliding contact sections for waterproof 4b, 1h composed of a recess, dust or sand can be scraped off by the flange sections 2d, 2h protruding in the radial directions when the flange sections are moved. Accordingly, there is no possibility that the flange sections 2d, 2h, are separated from the sliding surfaces "a", "b". Therefore, waterproof can be positively accomplished.
The flange section 2d of the sliding contact member 2A for waterproof on the front side slidably comes into contact with the sliding surface "a" of the sliding contact section 4b for waterproof outside the cylindrical section 4a, composed of a recess. Further, the flange section 2h of another sliding contact member 2B for waterproof on the rear side slidably comes into contact with the sliding surface "b" of the sliding contact section 1h for waterproof composed of the recess on the outer circumference of the shaft cylinder section 1g. Due to the above arrangement, even if the reel is dipped in water, it is possible to prevent water from entering the recess 1a of the opposite member 1 composed of the spool and also it is possible to prevent water from entering the through-hole 1c.
