Description

Fishing rod {FISHING ROD}

The present invention relates to a fishing rod, and more particularly, to an improvement in the grip structure of a fishing rod.

For example, the trout rod of the related art has a structure as shown in FIG. This pole 1 includes a grip 2, on which a pole body 3 is supported. An extension bat 4 may be attached to the rear end of the grip 2. This extension batt 4 is what is called a tuning part of the pole 1, and improves stability and operability of the pole 1.

That is, for example, when it is important to stabilize the pole tip in order to catch the artery of the trout of the management ground with low activity and high alertness, this extension bat 4 is attached, and this is the angler's shoulder. By holding the trout fishing rod 1 against, the shaking of the rod tip by reeling can be suppressed and the rod 1 can be stabilized. In addition, after the fish hits, the extension batt 4 is made to conform to the elbow, so that the operation of the pole 1 becomes easier.

By the way, in order to improve the stability of the pole by attaching the extension bat 4, the length L of the extension bat 4 must match the body of the angler.

However, in the conventional pole 1, it has a structure which only attaches or detaches the extension bat 4 to the rear end of the pole 1. As shown in FIG. For this reason, even if the said length L does not correspond to an angler's physique, and even if the extension bat 4 was attached, there existed a case where the maintenance of the pole 1 was not easy for some anglers.

Therefore, this invention provides the fishing rod which can set the length of the extension bat 4 according to the body shape of an angler.

(1) In order to achieve the above object, the fishing rod according to the present invention includes a fishing rod body, a grip portion for supporting the fishing rod body on one end side, an extension bat provided on the other end side of the grip portion, and an extension bat with respect to the grip portion. There is provided a positioning mechanism which is elastically supported and arranged at a desired position with respect to the grip portion.

According to this structure, an extension batt can be stretched and contracted with respect to a grip part, and it can further arrange | position in a target position. Thereby, the length of the extension batt can be adjusted in accordance with the body of the angler.

Moreover, the said positioning mechanism is set as the structure which detachably supports the said extension batt with respect to the said grip part, and can provide the high mounting part which mounts a high electric power when the said extension batt is removed.

According to this structure, when an extended bat is unnecessary, this can be removed. In that case, a high classic can be mounted to the high classical mounting part.

(2) The positioning mechanism is a posture formed between the accommodating portion which is formed inside the grip portion to which the extension batt can advance, and a tightening posture provided on the grip portion and tightly tightening the extension batt, and a release posture to release the tightening force. It can comprise a fixed part etc. which can be changed.

According to this structure, since the extension batt advances and retracts with respect to the inside of the grip part, even when the length of the extension batt is changed in various ways, the external dimensions and shapes of other parts such as the grip part are invariant. Therefore, the operability of a fishing rod is not impaired by changing the length of an extension batt. Further, since the extension batt is firmly tightened and fixed by the fixing unit, even if the positioning of the extension batt or the release of the positioning is repeated, a wound or the like can be prevented from occurring in the extension batt.

In particular, it is possible to have a structure in which the fixing portion tightly tightens the extension batt through the elastic member when the tightening position is set. When the extension batt is tightened using the elastic member in this way, it is possible to reliably prevent the wound or the like from occurring on the extension batt. Moreover, since the fixing force of the extension batt can be increased, reliable positioning of the extension batt becomes possible.

(3) Specifically, the fixing portion is provided with the other end of the grip portion, a boss for supporting the extension batt in the inserted state, a nut screwed into the boss in the state in which the extension batt is inserted; It is possible to set it as the structure which has the annular elastic member interposed between the said boss and the nut, and arrange | positioned so that the said extension bat may be disposed.

According to this structure, the relative position of the nut and the boss changes by screwing the nut, and the annular elastic member is elastically deformed by the nut and the boss. This state is the tightening posture of the fixed part. Since the annular elastic member is arranged as if the extension bat is important, i.e., it is sandwiched on the outer peripheral surface of the extension bat, when it is elastically deformed, the annular elastic member presses the outer peripheral surface of the extension batt. Therefore, the extension batt is tightly tightened by the annular elastic member and disposed with respect to the grip portion.

On the other hand, when the nut is turned in the reverse direction, the elastic deformation of the annular elastic member is returned, and the tightening of the extension batt by the annular elastic member is released. And this state is a release position of a fixed part, and an extension bat can expand and contract freely with respect to a grip part by this.

Here, the annular elastic member is held by a retainer, and the retainer can be set to slidably hold the outer circumferential surface of the annular elastic member. In this case, even when the annular elastic member is deformed and pressed by the extension batt, the nut can be sufficiently fixed and fixed to secure the extension batt. That is, if such a retainer is not provided, it is also necessary to consider that the screwing of the nut becomes insufficient due to the friction generated between the annular elastic members being pressed against the extension batt. However, by providing this retainer, even if the frictional force is increased, the retainer and the annular elastic member slide so that the nut can be sufficiently screwed.

(4) The extension batt may include a shaft portion supported by the positioning mechanism, a pad portion formed at an end of the shaft portion, and a slide mechanism for sliding the pad portion in the axial direction with respect to the shaft portion.

According to this configuration, when using the extension batt, the pad portion can be brought into contact with the angler's shoulder or elbow. At this time, since the pad part slides with respect to the extension batt, the length of the extension batt can be finely adjusted.

The slide mechanism can be configured to have a screwed portion formed on the shaft portion side and a pinned portion formed on the pad portion side. In this case, since the pad portion engages with the shaft portion through the screw structure, the pad portion can be precisely slid with respect to the shaft portion. This has the advantage that the length of the extension bat can be finely adjusted.

In addition, it is possible to provide a braking mechanism for braking the sliding of the pad portion relative to the shaft portion. In this way, it is possible to prevent the pad part from inadvertently sliding unless the pad part is operated against the braking force by the braking mechanism with the intention of sliding the pad part against the shaft part. Therefore, there is an advantage that the length of the extension bats once adjusted can be maintained.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described.

(1) General description and features of the embodiment

1 is a front view of a fishing rod according to an embodiment of the present invention.

As shown in the figure, this fishing rod 10 has a fishing rod main body 11, a grip part 12, and an extension batt 13. The fishing rod main body 11 is supported by the one end side of the grip part 12, and the extension bat 13 is provided in the other end side of the grip part 12. As shown in FIG.

The fishing rod main body 11 is formed in elongate rod shape, and can be manufactured by a well-known method, for example, forming carbon fiber into a cylindrical shape. Although not shown, a guide member for guiding the fishing line is appropriately disposed at the required position of the fishing rod main body 11.

The grip portion 12 includes a front grip 14, a rear grip 15, and a reel seat 16 interposed therebetween.

The fishing rod main body 11 penetrates the front grip 14. The front grip 14 has a known structure and is screwed onto the reel seat 16. The front grip 14 has a main body 17 and a front hood 18, and has a known structure. The front hood 18 is rotatably supported by the main body 17. When the main body 17 is rotated, the whole front hood 18 moves with respect to the reel seat 16 in the axial direction (left-right direction in drawing).

In addition, the rear grip 15 has a main body 19 and a rear hood 20, and the rear hood 20 is fixed to the main body 19. In addition, the reel sheet 16 has a flat reel mounting surface 21. By rotating the front grip 14 in a state in which the reel leg 21 is in contact with the reel mounting surface 21, the reel leg is fixed in a state where the reel leg is sandwiched between the front hood 18 and the rear hood 20. do.

2 is a partially enlarged cross-sectional view showing the structure of the rear grip 15 and the extension batt 13. It demonstrates with reference to FIG.

The characteristic of this embodiment is that the extension bat 13 is supported by the positioning mechanism 22 with respect to the rear grip 15, and by adopting such a support structure, the extension bat 13 has a rear grip. It is possible to expand and contract in the axial direction (left and right direction in the drawing) with respect to (15), and to be arranged at a desired position. Hereinafter, it demonstrates in detail.

(2) extended bat

The extension batt 13 is provided at the rear end (the other end side) of the grip part 12 as a tuning member for improving the operability of the fishing rod 10. The extension batt 13 has a shaft portion 23 and a pad portion 24.

Although the shaft part 23 can be comprised by metals, such as a titanium alloy, for example, it can also be comprised by resin etc., if sufficient rigidity can be ensured. In the present embodiment, the shaft portion 23 is provided with a large diameter portion 25 (smaller diameter portion) and a smaller diameter portion 26 with a smaller diameter in succession thereof, but the shaft portion 23 has a constant outer diameter. It is also possible to. The shaft part 23 is formed in the shape of a hollow pipe, and the piston member 27 is fitted in the front end part (left end part in drawing). The piston member 27 not only improves the rigidity of the end portion of the shaft portion 23, but also the shaft portion 23 is slid with respect to the rear grip 15 as will be described in detail later. At that time, sliding of the shaft part 23 can be made smooth.

When the pad part 24 operates the fishing rod 10, it contacts a part of a fisherman's body (shoulder etc.). The pad portion 24 is connected to the right end of the shaft portion 23. In this embodiment, the pad part 24 is formed in the column shape, and can be comprised, for example by urethane resin. In addition, the end surface 28 of the pad part 24 is formed in the curved surface as shown in the figure. As a result, the pad portion 24 can be brought into good contact with the body of the angler.

(3) positioning mechanism

The positioning mechanism 22 has a fixing portion 29 provided on the rear grip 15 and a storage portion 30 formed inside the rear grip 15.

This storage part 30 forms the space in which the axial part 23 of the extended bat 13 is inserted, and the length of the extended bat 13 is advanced by advancing and retreating the axial part 23 to the storage part 30. L changes. Specifically, the accommodating part 30 can be comprised by forming the rear grip 15 in hollow pipe shape.

In this embodiment, a sleeve 31 is attached to the housing 30 (that is, the inner wall surface of the rear grip 15). It is possible to make the sliding of the said shaft part 23 smoother by this sleeve 31. FIG. The sleeve 31 is formed in a thin hollow pipe shape, and protrudes outward from the rear end of the rear grip 15 as shown in the figure. The protruding portion of this sleeve 31 functions as a base for providing the fixing portion 29. Moreover, it is also possible to remove this protruding part, and to make the cross section of the sleeve 31 into the same surface as the rear end surface of the rear grip 15. FIG.

The fixing portion 29 includes a boss 32 attached to the rear grip 15, a nut 33 screwed thereto, and an elastic member 34 interposed between the boss 32 and the nut 33. Have In this embodiment, the decorative cap 35 is attached to the boss 32. In addition, a decorative ring 36 and an O ring 37 are interposed between the nut 33 and the rear grip 15.

3 is an enlarged cross-sectional view of the fixing portion 29. It demonstrates with reference to the said drawing.

The boss 32 is formed in substantially cylindrical shape, and can be comprised by resin etc. other than a metal, for example. The shape of the boss 32 is demonstrated in detail. The boss 32 has a large diameter part 39 in which the flange part 38 was formed, and the small diameter part 40 continuous to the large diameter part 39. The male screw 44 is formed in the large diameter part 39.

When the boss 32 is mounted, the boss 32 is inserted into the sleeve 31. And the flange part 38 adheres to the rear end surface of the rear grip 15 using existing fixing means, such as an adhesive agent. In this state, the decorative ring 36 is arranged to surround the flange portion 38. This decorative ring 36 may be eliminated.

Next, the nut 33 is formed in the substantially cylindrical shape as shown in the figure, and can be comprised by resin etc. other than a metal, for example. In the present embodiment, the nut 33 has a large diameter portion 41 and a small diameter portion 42 (classic mounting portion) whose diameter is subsequently reduced, and the end portion 43 is formed by the portion whose diameter is reduced. The back part is formed. The female screw 45 is formed in the large diameter part 41, and this female screw 45 is screwed together with the said male screw 45. As shown in FIG.

At the distal end side of the small diameter portion 42, an annular projection 46 is formed which projects outward in the radial direction of the small diameter portion 42. This annular projection 46 is for attaching the cap 35, but this may be eliminated. Moreover, the female screw 47 is formed in the inner peripheral surface of the small diameter part 42. Although this female screw 47 is demonstrated in detail later, when attaching | removing the extended bat 13, it is for attaching the high thread 48 (refer FIG. 4).

Next, the elastic member 34 can be comprised by nitrile rubber (NBR) etc., for example, and is formed in ring shape. In this embodiment, this elastic member 34 is held by the retainer 49 and is attached to the nut 33 together with the retainer 49.

The retainer 49 can be comprised by metals, such as an aluminum alloy, silicone resin, etc., for example, and is formed in the shape of a bowl which makes the elastic member 34 important. The elastic member 34 and the retainer 49 are not fixed, but only the elastic member 34 is accommodated in the retainer 49. For this reason, the elastic member 34 can slide in the holder 49 freely along the circumferential direction. The frictional force generated between the elastic member 34 and the retainer 49 depends on the surface pressure between the two members. However, even when the surface pressure increases by the structure of the retainer 49 made of the above materials, both of them are fixed. You can move without doing.

The holder 49 is attached to the end 43 formed in the nut 33 in a state where the elastic member 34 is accommodated therein. The nut 33 on which the elastic member 34 is mounted is covered by the boss 32 from the large diameter portion 41 side, and the female screw 45 of the nut 33 and the male screw 44 of the boss 32 are screwed together. Let's do it. Furthermore, when the nut 33 is screwed in, the distance between the front end of the boss 32 (the front end of the small diameter portion 40) and the end 43 of the nut 33 is shortened. In addition, since the O-ring 37 is provided, the tip of the nut 33 directly abuts the decorative ring 36, thereby preventing damage or the like from occurring.

The cap 35 is made of nitrile rubber (NBR) or the like, for example, and is attached to the small diameter portion 42 of the nut 33. Since the said annular projection 46 is formed in this small diameter part 42, the cap 35 can be engaged with the annular projection 46 by elastically deforming. First of all, even when there is no annular projection 46, it is also possible to engage the small diameter portion 42 by the urgency due to the elastic deformation of the cap 35.

(4) how to use fishing rod

Next, how to use this fishing rod 10 is demonstrated with the effect of each part.

It demonstrates with reference to FIG. This fishing rod 10 can be used for trout fishing. When the front grip 14 is rotated, the front grip 14 moves to the left in the drawing with respect to the reel seat 16, and the distance between the front hood 18 and the rear hood 20 is widened. When the leg portion of the reel is placed on the reel mounting surface 21 of the reel seat 16 and the front grip 14 is rotated in the reverse direction again, the distance between the front hood 18 and the rear hood 20 becomes narrow, The reel is firmly fixed to the reel seat 16.

In order to ensure stability in the operation of the fishing rod 10, the extension batt 13 can be used. When using this, an angler can hold | maintain the fishing rod 10 by holding the pad part 24 of the extension bat 13 a shoulder etc., holding the grip part 12, and can support and operate.

Next, a description will be given with reference to FIG. 2. In this fishing rod 10, since the positioning mechanism 22 is provided, the extension bat 13 can be expanded and contracted with respect to the rear grip 15 in the axial direction (the direction of the arrow 50 in the figure). Furthermore, by operating the positioning mechanism 22 as described later, the extension bat 13 can be arranged and fixed at a desired position.

Therefore, since the length L of the extended bat 13 can be adjusted in accordance with the body of the angler, the operability and stability of the fishing rod 10 are significantly improved. Therefore, for example, even when catching the trout of a trout with a high fishing pressure of a management fishing ground, since the tip of the fishing rod 10 can be stabilized, the shaking of the tip by reeling can be suppressed, and a delicate vein can be caught correctly. have. In addition, after the fish hits, by operating the extension batt 13 along the elbow, the fishing rod 10 can be easily operated.

On the other hand, the extension bat 13 may be unnecessary depending on the situation of the fishing ground. In that case, the extension bat 13 can be pulled out from the rear grip 15. In that case, the cap 35 mentioned above can be removed and the high classical 48 as shown in FIG. 4 can be attached.

Here, an example of the high classical 48 is demonstrated with reference to FIG. The classical 48 has a cylindrical main body 52 and a flange 51 formed at an end of the main body 52. An O-ring 53 is disposed at the boundary between the main body 52 and the flange 51. The outer diameter of the main body 52 corresponds to the inner diameter of the small diameter part 42 of the said nut 33, and the male screw 54 is formed in the outer peripheral surface of the main body 52. As shown in FIG.

After the cap 35 is removed, the main body 52 of the high power 48 is screwed to the small diameter portion 42 of the nut 33. As a result, the male screw 54 of the high thread 48 is screwed into the female screw 47 of the small diameter portion 42, and the high thread 48 is attached to the rear end of the grip portion 12.

In particular, in the present embodiment, when the extension bat 13 is stretched and contracted, the structure moves forward and backward with respect to the housing portion 30 in the rear grip 15, and therefore, even when the length L of the extension bat 13 is changed in various ways. The external dimensions and shapes of other parts such as the grip part 12 do not change. Therefore, the operability of the fishing rod 10 is not impaired by changing the said length L. FIG.

Moreover, since the structure which tightens and fixes the extension batt 13 by the fastening part 29 is employ | adopted, when positioning the extension batt 13, it hurts the extension bat 13, especially the axial part 23. There is an advantage to prevent back.

Moreover, since the fixing part 29 is a structure which tightens the extension batt 13 firmly using the elastic member 34, it can reliably prevent a damage etc. to the extension batt 13. FIG. In addition, by tightening firmly through the elastic member 34, the fixing force of the extension batt 13 can be increased, and reliable positioning of the extension batt 13 can be performed.

A detailed operation of the fixing unit 29 will be described with reference to FIGS. 2 and 3.

After the angler optimizes the length L of the extension bat 13, the nut 33 is screwed. As a result, the relative position of the nut 33 and the boss 32 changes, so that the elastic member 34 has a distal end face of the small diameter portion 40 of the boss 32 and the small diameter portion 42 of the nut 33. It is sandwiched between the rear end faces. In addition, when the nut 33 is tightened, the annular elastic member 34 elastically deforms in the radial direction. The posture of the fixed part 29 at this time is defined as a tightening posture. When the fixed portion 29 is in a tightening position, the elastic member 34 presses the shaft portion 23 of the extension batt 13. That is, the extension batt 13 is tightly tightened by the elastic member 34 and is disposed with respect to the grip portion 12.

On the other hand, when the nut 33 is turned in the opposite direction to the above direction, the relative positions of the nut 33 and the boss 32 change, and both of them carry over. The posture of the fixed part 29 at this time is defined as a release posture. When the fixing portion 29 is in the release position, the elastic deformation of the elastic member 34 is restored, and the tightening of the extension batt 13 is released, and the grip portion 12 can be freely stretched and contracted.

In this manner, in the fishing rod 10 according to the present embodiment, the positioning of the extension bat 13 can be easily or reliably released by changing the posture of the fixing portion 29.

In particular, in this embodiment, the elastic member 34 is held by the retainer 49, and the retainer 49 and the elastic member 34 are relatively slidable as described above. For this reason, even when the elastic member 34 deforms and is pressed by the extension batt 13, the extension batt 13 can be firmly fixed by screwing the nut 33 sufficiently.

In detail, if the retainer 49 is not provided, the nut is passed through the elastic member 34 by friction generated between both when the elastic member 34 is pressed by the extension batt 13. There is a possibility that the shaft portion 23 of the 33 and the extension batt 13 is in a so-called "twisted state" and the screwing of the nut 33 becomes insufficient. However, by providing the retainer 49, the retainer 49 and the elastic member 34 slide as described above, so that the nut 33 can be sufficiently screwed.

(5) Modified Example

Next, the modification of the said Example is demonstrated.

5 is an exploded perspective view for illustrating the structure of the extension batt 60 according to the modification of the embodiment.

The extension batt 60 by this modification is the slide part 63 for sliding the shaft part 61, the pad part 62 provided in this, and the pad part 62 along the axial direction of the shaft part 61. FIG. ). The characteristic of this modification is that in the above embodiment, the pad portion 24 is fixed to the shaft portion 23 (see FIG. 1), whereas in the present modification, the pad portion 62 is directed to the shaft portion 61. By sliding, the length L of the extension batt 60 can be adjusted finely.

6 is a cross-sectional view of the shaft portion 61. This will be described with reference to FIGS. 5 and 6.

The shaft portion 61 is formed in a cylindrical shape. On the inner circumferential surface of one end side of the shaft portion 61, a female screw 64 (threading portion) is formed. In addition, the other end side of the shaft portion 61 is provided with a piston member 27 (see FIG. 2) as shown in the above embodiment although not shown, and is provided to the rear grip 15 via the positioning mechanism 22. It is installed.

A groove portion 65 extending in the axial direction is formed on the outer circumferential surface of one end side of the shaft portion 61. The groove portion 65 engages with the pad portion 62 to guide sliding of the pad portion 62 with respect to the shaft portion 61. Although the groove part 65 is formed only in one side of the shaft part 61 in FIG. 5, the groove part 65 is also provided also in the opposite side to the shaft part 61 in practice (refer FIG. 6).

FIG. 7 is a cross-sectional view of the pad portion 62, and illustrates the structure of the pad portion 62 and the engagement relationship with the slide mechanism 63 in detail. It demonstrates with reference to FIG. 5 and FIG.

The pad portion 62 includes a screw shaft 66 and a slide pad 67 connected thereto.

As shown in Fig. 5, the screw shaft 66 has an elliptical cross section, and a male screw 68 (pinched portion) is formed on the outer circumferential surface thereof. One end (left end in FIG. 5) of the screw shaft 66 is inserted into the shaft portion 61 as shown in FIG. 6, and the female screw 64 and the screw shaft 66 of the shaft portion 61 are fixed. The male threads 68 are screwed together. Therefore, by rotating the screw shaft 66, the screw shaft 66 and the shaft portion 61 move and slide relatively in the axial direction. As shown in FIG. 7, the screw shaft 66 is inserted into the slide pad 67 and is fixed to the end member 69 of the slide pad 67. As the fixing of the end member 69 and the screw shaft 66, known fixing means such as an adhesive can be adopted.

As shown in FIG. 7, the slide pad 67 includes an inner cylinder 70 and an outer cylinder 71, a pivot pin 72 fitted into the outer cylinder 71, and the end member 69. .

The inner cylinder 70 is formed in the cylindrical shape, and the engaging projection 73 protrudes in the left end side in the figure. The engaging projection 73 is provided with a pair so as to oppose the inner surface of the inner cylinder 70, and is provided to extend only by a predetermined length along the axial direction. The inner cylinder 70 is fitted to the shaft portion 61, and the engagement protrusion 73 engages the groove portion 65 of the shaft portion 61 in the state. The groove part 65 and the engagement protrusion 73 are engaged so that sliding is possible.

In this modification, the brake mechanism 74 is equipped in the right end part in the figure of the inner cylinder 70. As shown in FIG. The braking mechanism 74 applies a predetermined braking force to sliding of the pad portion 62 with respect to the shaft portion 61. The braking mechanism 74 will be described later.

The outer cylinder 71 is formed in the cylindrical shape, and has the large diameter cavity part 75, the small diameter cavity part 76, and the rotation pin mounting recess 77 inside. The inner diameter of the large diameter cavity part 75 respond | corresponds to the outer diameter of the said inner cylinder 70, and the inner cylinder 70 is fitted and fixed to this large diameter cavity part 75. As shown in FIG. The small diameter cavity part 76 is comprised by continuing the large diameter cavity part 75 and reducing the large diameter cavity part 75. And the rotation pin attachment recessed part 77 is formed continuously in the small diameter cavity part 76, and is formed in the key cavity part provided with the head part 78. As shown in FIG.

The rotation pin 72 is formed in the columnar columnar shape, and has the small diameter part 79 and the large diameter part 80 extended in diameter successively. The outer diameter of the small diameter portion 79 corresponds to the inner diameter of the head 78, and the small diameter portion 79 is fitted into the head 78. The distal end portion of the small diameter portion 79 has an elongated portion 81 as shown in the drawing, and the elongated portion 81 is fitted into the pivot pin mounting recess 77. Since the pivot pin 72 is only fitted to the outer cylinder 71, the rotation pin 72 can be rotated with respect to the outer cylinder 71.

In the center of the rotation pin 72, a through hole 82 is provided along the axial direction. The screw shaft 66 penetrates the through hole. As described above, the end portion 83 is fixed to the end member 69. The rotation pin 72 and the screw shaft 66 are relatively rotatable.

The end member 69 is formed in the cap shape which covered the rotation pin 72, and is fixed to the circumferential surface of the large diameter part 80 of the rotation pin 72. As shown in FIG. Moreover, also in this modification, the cross section 84 of the end member 69 is formed in the curved surface. The inside of the end member 69 is provided with the fixing hole 85 in the center part, and the said screw shaft 66 is fitted in this fixing hole 85. As shown in FIG.

Next, the braking mechanism 74 will be described.

As described above, the braking mechanism 74 is disposed inside the inner cylinder 70 and brakes the rotation of the screw shaft 66. FIG. 8 is an exploded perspective view of the braking mechanism 74, and FIG. 9 is a perspective view of the rotating plate 86, which is a component of the braking mechanism 74, as viewed from the back side. As shown in this figure, the brake mechanism 74 is configured as a single unit.

The braking mechanism 74 is provided with the base block 87, the braking pin 88 provided in this, the said rotating plate 86, and the fixed spring 89. As shown in FIG.

The base block 87 is formed in cylindrical shape, and the rotating plate accommodating part 90 is formed inside. The inner diameter of the rotating plate accommodating part 90 corresponds to the outer diameter of the rotating plate 86, and the rotating plate 86 is accommodated in the base block 87 suitably. The bottom surface 91 of the rotating plate accommodating portion 90 is provided with a brake pin accommodating portion 92. In FIG. 8, only one braking pin receiving portion 92 is shown, but a plurality of these may be provided.

Moreover, the protrusion part 97 which protrudes inward is integrally formed in the end surface 96 of the base block 87. As shown in FIG. This projecting part 97 is for attaching the fixed spring 89.

The braking pin 88 is accommodated in the braking pin accommodation portion 92 via a spring 93. The braking pin 88 has a base portion 94 accommodated in the braking pin accommodation portion 92 and a pressing portion 95 formed continuously thereto. The tip of the pressing portion 95 is formed in a nearly spherical shape.

It demonstrates with reference to FIG. 8 and FIG. As for the rotating plate 86, the elliptical hole 98 is penetrated by the center part. The inner surface shape of this hole 98 corresponds to the external shape of the said screw shaft 66, and the screw shaft 66 has penetrated the rotating plate 86 (refer FIG. 7). The rear face of the rotating plate 86 is provided with a radially small hole 99. The small hole 99 is fitted with the pressing portion 95 of the brake pin 88 with the rotating plate 86 mounted to the base block 87.

The inner surface of the small hole 99 is formed in a curved surface. In addition, the braking pin 88 is elastically biased to the rotating plate 86 side by the spring 93. For this reason, the pressing part 95 of the braking pin 88 fits snugly into the small hole 99. That is, the free rotation of the rotating plate 86 is restricted by the engagement force between the braking pin 88 and the small hole 99. However, since the inner surface of the small hole 99 is formed as a curved surface, and the pressing portion 95 of the brake pin 88 is formed in a nearly spherical shape, the rotating plate 86 rotates against the engagement force of both. The pressing portion 95 of the braking pin 88 is inserted into the small holes 99 adjacent to each other in turn. That is, when rotating the rotating plate 86, it is in the state which fixed brake always applied. In addition, by increasing the number of the braking pins 88, the engagement force between the braking pins 88 and the small hole 99, that is, the braking force of the rotating plate 86 is increased.

The fixed spring 89 can be comprised, for example with the spring steel, and is formed in substantially regular pentagon in this modification. After attaching the rotating plate 86 to the base block 87, the rotating plate 86 is inserted between the rotating plate 86 and the protrusion 97 of the base block 87 with the fixing spring 89 interposed therebetween. It is preventing this being pulled out.

It demonstrates with reference to FIG. 5 and FIG. As described above, the screw shaft 66 of the pad portion 62 is fixed to the end member 69 through the slide pad 67. This end member is rotatable with the rotation pin 72 and the screw shaft 66. The screw shaft 66 is screwed onto the shaft portion 61.

Therefore, according to this modification, when using the fishing rod 10, the terminal member 69, the rotating pin 72, and the screw shaft 66 are rotated by gripping and rotating the terminal member 69 by hand. Slid about). At this time, the inner cylinder 70 and the outer cylinder 71 of the slide pad 67 are pressed by the rotary pin 72 to move in the same direction as the sliding direction of the screw shaft 66. However, since the engaging projection 73 of the inner cylinder 70 and the groove part 65 of the shaft part 61 engage, the inner cylinder 70 and the outer cylinder 71 do not rotate with the screw shaft 66, either. And the shaft 61 is slid in the axial direction.

That is, in this modification, since the pad part 62 slides axially with respect to the axial part 61 via the said slide mechanism 63 only by operating the end member 69, the extended batt 60 is carried out. The length L of can be finely adjusted. As a result, the said length L can be adjusted according to the body shape of an angler, and the operability and stability of the fishing rod 10 are further improved.

In particular, since the slide mechanism 63 is formed by the screw structure of the screw shaft 66 and the shaft portion 61 as in the present modification, the pad portion 62 can be precisely slid with respect to the shaft portion 61. There is an advantage to this.

In addition, in this modification, the said braking mechanism 74 is provided, and the screw shaft 66 penetrates into the rotating plate 86 of the braking mechanism 74 (refer FIG. 8). And this rotating plate 86 rotates in the base block 87 with the rotation of the screw shaft 66. As shown in FIG. Moreover, as mentioned above, the braking force is always applied to the rotation of the rotating plate 86. Therefore, by providing the braking mechanism 74, the brake is always applied to the sliding of the pad portion 62.

For this reason, the pad part 62 may be inadvertently operated unless the end member 69 is operated against the braking force by the brake mechanism 74 with the intention of sliding the pad part 62 with respect to the shaft part 61. ) Can be prevented from sliding. Therefore, there is an advantage that the length L of the extension batt 60 once adjusted can be maintained.

In addition, the braking mechanism 74 obtains a braking force by the engagement force between the braking pin 88 and the rotating plate 86, and the pressing portion 95 of the braking pin 88 makes a small hole ( 99). Therefore, when the rotating plate 88 rotates as mentioned above, since the said press part 95 sequentially fits into the adjacent small hole 99, a sound like "Kachikachi" generate | occur | produces. By appropriately setting the materials of the pressing unit 95 and the rotating plate 88, it can be said that this generated sound has a sense of quality as a good quality, and even the fishing rod 10 can produce a sense of quality. have.

According to the present invention as described above, since the length of the extension bat can be adjusted to the body of the angler, the operability and stability of the fishing rod can be improved. Moreover, since this extension bat is detachable, it can be removed when it is unnecessary and can provide the fishing rod which is easy to use depending on a situation.

Further, by adopting a structure for finely adjusting the length of the extension batt, the length of the extension batt can be matched by the angler's physique, and thus the operability and stability of the fishing rod can be further improved.
