Description

Spinning Reel for Fishing {SPINNING REEL FOR FISHING}

The present invention relates to a spinning reel for fishing provided with a thread slipping prevention member for preventing the fishing line from penetrating into the rotor during a fishing operation.

Conventionally, a fishing spinning reel has a rotor composed of a pair of support arms and a cylindrical upper portion for supporting a bale support member, and a flange portion before and after the fishing line winding body portion, and interlocks with the rotation of the rotor and further includes the rotor. It has a spool reciprocating in the axial direction of the rotating shaft of the rotating shaft, and is configured to wrap a fishing line around the spool by the rotation of the rotor. And it is known to provide a thread slipping prevention member to such a fishing spinning reel to prevent the fishing line from coming back from the rear flange portion of the spool.

This thread fall prevention member is known in various configurations. For example, Japanese Utility Model Registration No. 25003030 and Utility Model Registration No. 2532864 support the thread loss prevention member rotatably on the spool shaft and are integral with the rotor. Disclosed is a configuration for axially moving integrally with a spool or spool shaft while rotating. These well-known thread slipping prevention members have a base end rotatably supported by the spool shaft, an annular portion located outside the cylindrical portion (skirt portion) formed at the rear flange portion of the spool, and the base end and the annular portion. The connecting frame which connects is provided, and the said annular part cooperates with the annular wall which protrudes outward in the radial direction formed in the cylindrical part of the spool, and the anti-entanglement effect is improved.

According to the above-described configuration of the thread slipping prevention member, since the cylindrical portion of the spool is located inside the annular portion of the thread slipping prevention member, an annular wall protruding radially outward as described above is formed in the cylindrical portion. Otherwise, the fishing line falls between the annular portion of the thread slipping prevention member and the cylindrical portion of the spool.

By the way, in a spool having a protruding portion in the cylindrical portion, it is necessary to cut the cylindrical portion or to mold the entire spool by a mold. In the former case, the cost increases, and in the latter case, the cylindrical portion is thick. There is a problem that the weight increases due to the thickening.

Moreover, since the connecting frame which forms the base end part and the annular part of a thread release prevention member needs to be connected to the lower end of an annular part by exchanging the cylindrical part of a spool, a connection frame becomes long, and a fallout prevention member becomes a part of a connection frame part. There is a problem that it tends to bend. As a result, there is a problem that the gap between the annular portion and the spool changes, and the fishing line tends to fall into the gap.

The present invention also relates to an improvement in a spinning reel for fishing provided with a rotor having a fishing line guide that rotates in conjunction with the rotation of the handle and winds the fishing line around the spool.

In general, in a fishing spinning reel, when the fishing line wound around the spool is released, the fishing line winding state of the spool may collapse and the fishing may be released. Then, the influence of the fishing line twisting is applied to the tension change or wind influence during the winding operation of the fishing line. Sticking problem is easy to occur.

Therefore, in order to prevent these problems, it has conventionally been known that a thread entanglement preventer is provided between the spool and the support arm of the rotor (see Patent Document 1, for example).

(Patent Document 1)

Japanese Utility Model Registration No. 2532864

In the technique disclosed in Patent Literature 1, the thread slipping prevention tool as the thread entanglement preventing body is provided between the spool and the spool shaft, is rotatably supported by the spool shaft, and is moved back and forth along the spool shaft. In this case, an engaging portion protruding radially outward is provided in the annular portion of the rear portion of the thread slipping prevention tool, and the engaging portion is formed along the axial direction on the spool side opposing portion of the support arm of the rotor. It is fitted with a margin in the recessed engagement groove. The thread slip prevention tool moves back and forth with the spool while rotating in conjunction with the rotation of the rotor.

However, in such a configuration, since the slipping prevention tool also moves back and forth along the spool while interlocking with the rotor at high speed during the fishing line winding operation in which the rotor rotates at high speed, the engaging portion and the rotor of the slipping prevention tool The abnormal sound occurs due to the influence of the engagement margin with the concave engagement groove of the support arm and the sliding state at the same time.

In addition, a relatively large engagement margin (a rattling in the rotational direction) is required in a configuration in which the engagement portion of the thread slipper is engaged with the concave engagement groove of the support arm of the rotor and rotates back and forth while rotating. Due to the influence of this margin, the problem that the engaging portion detaches from the concave engaging groove at the time of winding operation (especially when the winding speed changes abruptly) is likely to occur.

The present invention has been made on the basis of the above-described problem, and a thread-separation preventing member which can reliably prevent the fishing line from penetrating into the cylindrical upper part of the spool (thread is pulled out) without forming a protrusion in the cylindrical upper part of the spool. It is an object to provide a spinning reel for fishing provided.

In addition, the object of the present invention is to effectively prevent the fishing line from slipping into the gap between the spool and the rotor by the slipping prevention body without generating an abnormal sound. It is to provide a fishing reel for fishing that can prevent falling out of engagement.

The pinion 10 is rotatably supported through a bearing, the spool shaft 11 extending in a direction orthogonal to the handle shaft 7 in the cavity portion and having the spool 5 attached to the tip side thereof. ) Is passed through and supported in the axial direction.

In addition, the pinion 10 is engaged with an oscillating mechanism for moving the spool shaft back and forth. The oscillating mechanism is engaged with the worm shaft 12 extending parallel to the spool shaft and the spiral groove 12a of the worm shaft 12, and screwed to the proximal end of the spool shaft 11. It has the engaging part 13 attached. A gear 15 meshing with the pinion 10 is attached to an end portion of the worm shaft 12, and the worm shaft 12 is driven to rotate through the pinion 10 and the gear 15 so that the spool shaft ( 11 is moved back and forth through the engaging portion 13 guided in the groove 12a.

The pinion 10 extends out toward the spool side, and the rotor 3 is attached via the nut 16 at the tip end thereof. In addition, the pinion 10 has a one-way clutch 17 attached to the middle portion thereof, and operates the one-way clutch by rotating the lever 18 attached to the outside of the reel unit 2 to operate the handle. It is designed to prevent reverse rotation.

The rotor 3 includes a cylindrical portion 3a and a pair of support arms 3b that rotate around the spool 5, and each of the pair of support arms 3b. At the front end portion of the bale 3c, the bale support member 3d attached to the proximal end of the bale 3c is freely rotated between the fishing line winding position and the fishing line discharge position. Moreover, one base end of the bale 3c is attached to the fishing line guide part 3e provided integrally with the bale support member 3d.

The said spool 5 is attached to the spool shaft 11 via the drag knob 19, and the fishing line winding trunk | drum 5a which a fishing line is actually wound up, and the flange part (front flange part formed before and behind) 5b and rear flange 5c are provided. In this case, 5 d of cylindrical parts (skirt parts) extended toward the reel main body side are integrally formed in the rear flange 5c.

On the rear end side of the spool 5, a thread slip prevention member 20 is arranged to prevent the fishing line wound around the winding trunk portion 5a from falling backward from the rear flange portion 5c.

The thread slipping prevention member 20 has a ring-shaped base end 21 having a hole 21a through which the spool shaft 11 is inserted, and a first annular portion 22 located behind the base end. ) And a second annular portion 23 positioned radially outward from the first annular portion 22 at the rear end of the first annular portion, wherein the proximal end portion 21 and the first annular portion are provided. The 22 extends toward the radially outer side from the base end 21 and is integrally connected by a predetermined number of connecting frames 25 that are bent toward the rear side from the tip end thereof.

In this case, the said 1st annular part 22 is located in the radial inside of the cylindrical part 5d of the spool 5, and is formed in the shape along the inner periphery of the cylindrical part 5d. Moreover, the said connection frame 25 is a shape which connects the base end part 21 and the 1st annular part 22 located in the radial direction outer side with respect to the base end part 21, ie, the base end part 21. As shown in FIG. It may be a shape extending outward from the radial direction from, and is not limited to the shape bent at the position as shown in the figure. Moreover, about the number of the connection frames 25, two or more may be formed and may be connected to a cylindrical part.

In addition, such a slipping prevention member 20 can be integrally formed with synthetic resins, such as ABS and PPS, metals, such as aluminum, etc., for example.

The first annular portion 22 and the second annular portion 23 are provided with outer circumferential surfaces 22a and 23a having a predetermined length in the axial direction together, and the first annular portion 22 and the second annular portion 23. The annular portion 23 is integrated through the wall portion 26 that is substantially perpendicular to the spool axial direction. Moreover, a pair of engagement protrusions 29 are formed in the said 2nd annular part 23 in the rear end side (reel main body side) of the outer peripheral surface 23a, These are respectively of the said rotor It engages with the engaging groove 3f extended in the axial direction formed in the inner surface of the support arm 3b.

The spool shaft preventing member 20 having the above-described configuration is rotatably supported by the spool shaft 11 via the bearing 28 at its proximal end 21 and reciprocated by the oscillating mechanism. It is supported by the spool shaft so that it can reciprocate integrally with (11). Moreover, the thread fall prevention member 20 is the cylindrical part 5d in which the said 1st annular part 22 was formed in the rear flange part 5c of the spool 5 in the state supported by the spool shaft 11. It has a predetermined clearance inside, and the 2nd annular part 23 is located in the back which becomes the reel main body side from the rear end edge of the cylindrical part 5d, The said engagement protrusion 29 is the support arm of a rotor. It engages with the engagement groove 3f formed in the inner side of 3b.

In this embodiment, the said wall-shaped part 26 and the 2nd annular part 23 are formed so that the outer peripheral surface 23a may be substantially equal to the outer peripheral surface of the cylindrical part 5d of the spool 5. In this case, the length in the axial direction of the outer circumferential surface 23a (the length from the position of the wall portion 26 to the base of the engaging projection 29) L effectively penetrates into the spool 5 of the fishing line. It is preferable to form so that it may become 2 mm or more so that the gap G between the trailing edge of the cylindrical part 5d and the front edge of the 2nd annular part 23 may have a fishing line spool 5 so that it may prevent. It is preferable to form it so that it may become 2 mm or less so that it may be hard to penetrate inside.

Next, the operation and effect of the fishing reel for fishing incorporating the slipping prevention member 20 configured as described above will be described.

In the above configuration, the rotor 3 is rotationally driven through the drive gear 9 and the pinion 10 by winding the handle, and the spool 5 is moved back and forth with the spool shaft 11 through the oscillating mechanism. Since the fishing line is moved, the fishing line is evenly wound around the winding trunk portion 5a of the spool 5 through the fishing line guide portion 3e. At this time, since the thread slipping prevention member 20 is supported by the spool shaft 11 so as to be movable, the engagement protrusion 29 and the support arm 3b are integrally moved back and forth with the spool 5 at the same time. By engaging with the engaging groove 3f formed in the), it rotates integrally with the rotation of the rotor 3.

If the fishing line is pulled back from the winding trunk 5a during such operation, the fishing line moves along the cylindrical portion 5d of the spool to the reel main body side, but the movement is prevented by the engaging projection 29. At the same time, intrusion into the spool 5 is prevented by the outer circumferential surface 23a of the second annular portion 23. Specifically, since the outer circumferential surface 23a of the second annular portion 23 has a predetermined length L in the axial direction, the fishing line intended to collide with the engagement protrusion 29 and move inward in the radial direction is Intrusion into the spool is effectively prevented by the outer circumferential surface 23a having a predetermined length.

Moreover, since the outer peripheral surface 23a of the 2nd annular part 23 is substantially coincided with the outer peripheral surface of the cylindrical part 5d of the spool 5, a step | step disappears between them, and, thereby, of a fishing line At the same time, even when the fishing line is moved to the rear of the cylindrical portion 5d, the hook can be smoothly pulled out and the thread entanglement and slipping can be effectively eliminated. In addition to the above configuration, the outer circumferential surface 23a of the second annular portion 23 may be configured to gradually expand in diameter as it moves toward the reel main body side.

In addition, according to the thread slipping prevention member 20 of the above-mentioned structure, since it is not necessary to form an annular protrusion part and a groove part in the outer peripheral surface of the cylindrical part 5d of the spool 5 (as in the conventional structure, it is flat It is possible to form the spool), so that the processing of the spool does not become complicated, and there is no increase in weight or increase in processing cost. Moreover, even if an existing spool is used, the thread slipping prevention member can be incorporated easily.

Furthermore, the thread-separation preventing member 20 of the above-described configuration forms the first annular portion 22 inside the cylindrical portion 5d of the spool 5, and particularly the inner surface of the first annular portion, Since the connecting frame 25 connected to the base end 21 is extended to the spool tip side, the length of the connecting frame 25 can be shortened. As a result, since the amount of warpage of the connecting frame 25 decreases and the rigidity of the entire thread loss preventing member 20 is improved, the clearance between the spool 5 and the thread loss prevention member 20 can be kept constant. The clearance is not inadvertently widened due to the tension of the fishing line and the like, and the effect of preventing slipping is improved.

4 and 5 are diagrams showing a second embodiment of the present invention, FIG. 4 is a diagram showing the configuration of the inside of the spool, and FIG. 5 is a perspective view showing the configuration of the thread fall preventing member. . In this embodiment, the same reference numerals are attached to the same parts as the above-described embodiments, and detailed description of the same components is omitted in the following description.

An annular protrusion which protrudes radially outward in the vicinity of the spool tip side of the outer circumferential surface 22a of the first annular portion 22 is used for the thread release preventing member 20 used in the spinning reel for fishing of this embodiment. 30) is formed.

Thus, by forming the annular protrusion part 30 in the front-end | tip part of the 1st annular part 22, even if a fishing line enters the inside of the spool 5, invasion of the fishing line in front of it (near the spool shaft) is prevented. The fishing line can be prevented and the entanglement of the fishing line to the spool shaft 11 can be more effectively prevented, and the fishing line can be easily returned to the normal state.

In addition, such an annular protrusion should just be formed in any position of the outer peripheral surface 22a of the 1st annular part 22. As shown in FIG.

Hereinafter, the third and fourth embodiments of the present invention will be described with reference to FIGS. 6 to 9.

The drive gear 103 is fixed to the handle shaft 102, and the pinion gear 113 meshes with the drive gear 103.

The pinion gear 113 is provided in the shaft 162 which extends in the direction orthogonal to the handle shaft 102 and is rotatably supported by the reel main body 101a via the bearing 160. The rotor 108 is integrally attached to the distal end of the shaft 162. The rotor 108 is provided with a pair of first and second support arms 123a and 123b, and the first ends of the bales 106 are attached to the front ends of the support arms 123a and 123b. And the second bail support members 124a and 124b are freely supported by the rotational movement so as to be assigned to the fishing line winding position and the fishing line discharge position through an allocation tool (not shown). In addition, one end of the bale 106 is attached to the fishing line guide 115 provided integrally with the first support member 124a.

The spool shaft 109 extending in the direction orthogonal to the handle shaft 102 penetrates the shaft cylinder 162. In this case, the spool shaft 109 is disposed concentrically with the shaft cylinder 162 and can be moved back and forth along the direction orthogonal to the handle shaft 102. Moreover, the spool 110 by which a fishing line is wound is attached to the front-end | tip part of the spool shaft 109. As shown in FIG.

The spool 110 includes a winding body portion 110a on which the fishing line is actually wound, a front flange portion 110b for regulating the front side of the rolled fishing line, and a rear flange portion 110c for regulating the rear side of the fishing line. It is provided, and is attached to the spool shaft 109 via the drag knob 130.

Moreover, the fishing reel 101 for fishing of this embodiment is provided with the oscillating mechanism (reciprocating tool) 165 for moving back and forth the spool 110 according to rotation of a handle.

The drawer camshaft 152 is connected to the pinion 113 via the gear 156, while the sliding body 154 has an engaging pin 158 that is always engaged with the drawer camshaft 152. It is installed.

Therefore, in such a configuration, when the pinion 113 is rotated through the drive gear 103 by the rotation operation of the handle, the rotor 108 rotates via the shaft 162 and the pinion 113 is engaged. The gear 156 rotates, and the drag cam shaft 152 also rotates with the rotation of the gear 156. At this time, the engaging pin 158 engaged with the cam groove 159 of the drag cam shaft 152 is moved back and forth in accordance with the rotation of the draw cam cam shaft 152, so that the sliding member 154 moves the drag cam cam shaft 152. Move back and forth along). As a result, the spool shaft 109 connected to the sliding member 154 through the fixing screw 190 moves back and forth. Therefore, the fishing line is wound around the winding trunk portion 110a of the spool 110 evenly through the fishing line guide portion 115.

Moreover, in the fishing reel 101 for fishing of this embodiment, a fishing line falls into the clearance gap between the rear flange part 110c of the spool 110, and the support arms 123a and 123b of the rotor 108, and a support arm ( 123a, 123b and the slipping prevention body 140 which prevents being entangled with the spool shaft 109 inside the reel main body are provided.

And a second annular shape extending axially from an end edge of the rear flange portion 110c to partially fill the axial gap formed between the rear flange portion 110c and the rotor 118 of the spool 110. A plurality of portions connecting the portion 142, the first annular portion 141, and the annular base end portion 145 ( In this embodiment, it consists of three) connecting frames 44. As shown in FIG.

Moreover, in the site | part (two places) of the 2nd annular part 142 which opposes each support arm 123a, 123b, the inner side surface (2nd annular part 142) of each support arm 123a, 123b is respectively. Engaging projections (engaging projections) 146 engaged with the concave grooves (guide portions) 170 formed on the side of the side opposite to each other are provided. These engaging projections 146 are located at angular intervals of about 180 degrees to each other in the circumferential direction of the second annular portion 142, and protrude radially from the end edge of the second annular portion 142. At the same time, it extends to fill the gap in the radial direction formed between the rear flange 110c of the spool 110 and the support arms 123a and 123b of the rotor 108.

In addition, the base end 145 of the slipping prevention member 140 is restricted in the axial movement with respect to the spool shaft 109 by the positioning washer 171. Therefore, the thread slipping prevention member 140 moves back and forth integrally (and thus) with the spool shaft 109 and at the same time cooperates with the rotation of the rotor 108 that is engaged via the engaging projection 146. 109). Moreover, the concave groove 170 of each support arm 123a, 123b which engages with the engagement protrusion 146 is the axial direction of the thread slip prevention body 140 which follows the front-back motion of the spool shaft 109.

Only a very small gap is formed between the O-ring 147 and the inner surface of the groove 70 to realize a smooth axial movement of.

Next, the operation of the above configuration will be described.

First, when the handle is rotated, the pinion 113 and the shaft 162 rotate through the drive gear 103, and the rotor 108 fixed to the shaft 162 rotates, and the oscillating mechanism 165 Through this, the spool shaft 109 moves forward and backward. At this time, since the thread slipping prevention member 140 is attached to the spool shaft 109, it is engaged with the spool shaft 109 integrally with the spool shaft 109, and is also engaged with the rotor 108 through the engaging projection 146. Therefore, it rotates with the rotor 108. At this time, the engaging projection 146 engaged with the concave groove 170 of the support arms 123a and 123b is circumferentially rotated from the rotor 108 via the wall surface of the groove 170 (rotational direction). While moving in the axial direction along the groove 170 while being subjected to a force), the O-ring 147 as the elastic member absorbs the rattling during the movement (the rattling in the circumferential direction), so that the occurrence of the abnormal sound none. In this case, the fact that the O-ring 147 is engaged with the engagement groove 148 and is hard to escape from the engagement projection 146 greatly contributes to the prevention of abnormal sound generation. That is, since the clearance between the groove 170 and the engaging projection 146 is always kept constant by the O-ring 147, this prevents rattling in the rotational direction, thereby preventing the occurrence of abnormal sounds. In addition, since the engagement projection 146 can be guided with a small engagement margin with the groove 170 by the interposition of the O-ring 147, the engagement projection 146 and the groove ( The engagement with 170 is not released.

In addition, during the winding operation, the thread slip prevention body 140 is supported by a fishing line falling into a gap between the rear flange 110c of the spool 110 and the support arms 123a and 123b of the rotor 108. It is prevented from being entangled with the arms 123a and 123b or the spool shaft 109 inside the reel unit. Specifically, the first annular portion 141 extends in the axial direction near the inside of the rear flange portion 110c of the spool 110 along the shape of the rear flange portion 110c, and also has a wall shape. The portion 143 extends in the radial direction from the first annular portion 141 to face the edge of the rear flange 110c in close proximity to the end edge of the rear flange portion 110c, and furthermore, the first annular portion through the wall portion 143. The rear flange portion 110c so that the second annular portion 142 continuous to 141 partially fills the axial gap formed between the rear flange portion 110c and the rotor 108 of the spool 110. The engagement protrusion 146 protrudes radially from the end edge of the second annular portion 142 and extends axially from the end edge of the rear flange portion 110c of the spool 110 and the rotor 108. Extends to fill the gap in the radial direction formed between the support arms 123a and 123b Since, the fishing line going into the gap between the rear side flange portion (110c) and the support arms (123a, 123b) of the spool (110), a further entry of the inside can be reliably prevented.

As described above, the fishing reel 101 for fishing of this embodiment is the groove 170 as a guide part formed in the support arms 123a and 123b of the rotor 108 via the O-ring 147 as the elastic member. Since the engagement protrusion 146 of the thread slip prevention body 140 engages and guides, it is possible to reliably prevent the occurrence of abnormal sounds when the device is rotated back and forth while rotating. In addition, the engagement margin between the slipping prevention member 140 and the guide groove 170 formed in the support arms 123a and 123b of the rotor 108 is reduced (absorption of irregular dispersion of dimensions due to the elastic action). Since it can be guided by, it is possible to prevent the falling off of the thread slip prevention body 140 during the winding operation.

Moreover, according to the spinning reel 101 for fishing of this embodiment, since the O-ring 147 can be elastically guided by the O-ring 147 to the engagement protrusion 146 of the slipping prevention body 140, it has a simple structure. It is easy to handle and it can comprise the engaging part of the fall prevention body 140 which does not fall out.

9, a fourth embodiment is shown. In the third embodiment, the O-ring 146 is attached to the engagement protrusion 146. In this fourth embodiment, the elastic member 180 is provided in the groove 170 of the support arms 123a and 123b. Is installed. In this case, the elastic member 180 is attached to the concave groove 181 formed along the axial direction on both sidewalls of the groove 170, respectively, and extends along the longitudinal direction of the support arms 123a and 123b. In addition, in this modification, although the 1st annular part 141 of the slipping prevention body 140 is spaced apart from the rear flange part 110c of the spool 110 at predetermined spacing, In the one annular portion 141, an annular protrusion 183 protruding in the radial direction is provided adjacent to the inner surface of the rear flange portion 110c of the spool 110. In addition, since the other structure is the same as that of 3rd Embodiment mentioned above, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

Therefore, according to the structure of this 4th Embodiment, the same effect as the 3rd Embodiment is acquired, and since the groove | channel does not need to be provided in the engagement protrusion 146, the engagement protrusion 146 is made into high intensity | strength. It can hold | maintain and the engagement protrusion 146 can be protected even if a huge load is applied to the fall prevention body 140. FIG.

As mentioned above, according to the said structure, the fishing reel for fishing which can reliably prevent a fishing line from falling (seals out) in the cylindrical upper part of a spool without providing a protrusion etc. in the cylindrical upper part of a spool can be obtained.

Further, as described above, according to the spinning reel for fishing of the present invention, the fishing line can effectively prevent the fishing line from falling into the gap between the spool and the rotor without causing abnormal sound, The fallout of the thread slip prevention body can be prevented.
