Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a spinning drag reel for fishing, particularly a rear drag mechanism.

[0002]

[Prior art]

 In a so-called rear drag mechanism in which a drag device is provided at the rear part of the reel body of a spinning reel, an engaging protrusion of a cylinder shaft that is slidably fitted only in the axial direction by an operating member on a spool shaft is engaged with an engaging part of a braking cylinder. It is known from Japanese Utility Model Laid-Open No. 4-21263 that the spool provided at the tip of the spool shaft can be engaged and disengaged so that the spool can be switched between a drag operating state and a spool free state.

[0003]

[Problems to be solved by the device]

 However, in the above method, when the spool free state in which the engaging protrusion of the cylinder shaft is disengaged from the engaging portion of the braking cylinder is switched to the drag operating state, when the fishing line withdrawing speed increases, the spool shaft rotates integrally. When a rotational force acts on the cylinder shaft, the engaging protrusion slides and engages with the engaging part of the braking cylinder while simultaneously receiving axial frictional resistance with respect to the spool shaft. However, there is a problem in that the engaging action of the engaging projection on the engaging part is not performed smoothly and reliably, and the spool cannot be swiftly and swiftly switched from the free state to the drag operating state. The present invention provides a rear drag mechanism for a spinning reel for fishing, which solves the above-mentioned problems in the rear drag mechanism and enables quick and smooth switching operation of the spool from the free state to the drag operating state. That is the purpose.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms an engaging projection on the outer peripheral surface of a cylindrical shaft that is fitted on a spool shaft by an operation member so as to be rotatable only in the axial direction. It is possible to switch the spool, which is fixed to the tip of the spool shaft, to be engageable and disengageable with the engaging part formed on the inner peripheral surface of the braking cylinder in which the braking member is interposed between the spool and the drag operating state and the spool free state. In the spinning reel for fishing described above, the engaging protrusion of the cylinder shaft is directed rearward to form a twisted protrusion in the reverse direction of the spool shaft, and the base end of the twisted protrusion is formed on the front portion of the braking cylinder. It is characterized in that it is fitted in a guide groove formed on the inner peripheral surface of the second braking cylinder supported by the main body so as to be guided.

The braking force of the second brake cylinder is formed so as to exert a slight braking action such as a notification of free rotation of the spool shaft by a click claw, and the switching means from the free state of the spool shaft to the drag operating state is Either automatic switching operation by turning the handle shaft or manual switching operation by the operating lever is allowed.

[0006]

[Action]

 According to the present invention, when the cylinder shaft, which rotates integrally with the spool shaft, is moved rearward by the operating member from the spool shaft free state, the twisting ridge, which is the engaging protrusion, moves in the guide groove portion of the second braking cylinder and the spool moves. The shaft is rotated by the rotating action of the shaft to move rearward and its tip end engages with the engaging part of the braking cylinder to switch the spool shaft to the drag operating state. When the shaft is moved forward, contrary to the above, the tip end of the twisted protrusion is disengaged from the engaging portion of the braking cylinder, and the spool shaft becomes freely rotatable.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A rear end portion of a spool shaft 2 provided with a spool 1 at its tip and reciprocatingly slid by a known sliding mechanism is formed into a truncated circular shaft portion 3. A cylindrical shaft 7 provided with an annular groove 4, a twisted ridge 5 and a bearing 6 in turn from the front end is fitted in a rotation stopper 3 so as to be slidable only in the axial direction, and the twisted ridge 5 is attached to a reel body 8. It is fitted in a guide groove portion 11 formed on the inner peripheral surface of a second braking cylinder 10 which is rotatably supported and has click teeth 9 on the outer periphery. On the other hand, on the rear part of the reel body 8, there is provided a braking cylinder 14 in which a braking member 12 of a drag mechanism is fitted on the outer side of the rear part and an engaging part 13 with which the twisted ridge 5 is engaged is provided on the inner side of the front part. The support portion 6 of the cylinder shaft 7 is slidably fitted in the braking cylinder 14 in the front-rear direction so that the distal end of the twisted ridge 5 is engaged with and disengaged from the engaging portion 13. Further, a gate-shaped actuating member 16 whose upper portion is pulled rearward by a spring 15 is axially attached to a reel body 8 substantially below the annular groove 4 of the cylindrical shaft 7, and the annular portion is provided in the middle thereof. A yoke 17 that engages with the groove 4 is installed.

An operating lever 20 having an operating piece 18 engaged with the upper rear side of the operating member 16 and a return piece 19 located in front of the operating body 18 is pivotally mounted on the reel main body 8. Further, the operating lever 20 is urged by the spring 21 so as to be distributed in opposite directions. Further, as is well known, the handle shaft 22 provided on the reel body 8 is provided with a drive gear 25 that meshes with a pinion 24 for rotating the rotor 23, and one or more drive gears 25 are provided on the back face of the drive gear 25. A return body 27 having a kick portion 26 is fitted therein, and a spring 28 for urging the return body 27 and a projection 29 for restricting the rotation of the return body 27 are provided on the back surface of the drive gear 25.

The reel body 8 between the return body 27 and the return piece 19 of the operating lever 20 has a return actuating body 31 urged by a spring 30 and engaged with the return piece 19, which is pivotally mounted on the reel body 8. When the 20 is in the upright position, the tip of the return actuating body 31 is held outside the turning locus of the kick portion 26 of the returning body 27, and when the operating lever 20 is in the backward turning position, the return actuating body 31 is held. Is configured to be held within the turning locus of the kick portion 26 of the return body 27. A restricting body 34 having a restricting projection 32 and an engaging projection 33 is held by a biasing spring 35 and pivotally supported by the reel body 8 on the upper front side of the operating member 16. The portion 33 is configured to be engaged with the engaging portion 36 of the return actuating body 31 at the standing position of the operation lever 20 and to regulate the forward rotation of the operating member 16 by the regulating projection 32.

A click claw of a leaf spring (not shown) is engaged with the click tooth 9 of the second braking cylinder 10 provided on the cylindrical shaft 7, and a braking member is provided on the lower portion of the outer peripheral surface of the second braking cylinder 10. 37 is provided so that it can be pressed into contact with a knob 38 provided on the reel body 8, and the braking force of the braking member 12 of the drag mechanism can be adjusted by a drag adjusting knob 39 as is well known. .

Therefore, as shown in FIG. 2, when the operating lever 20 is in the upright state of the solid line, the operating member 16 is pulled by the spring 15, and the yoke 17 of the operating shaft 16 moves the cylinder shaft 7 so that the front end of the twisted protrusion 5 is moved. The brake cylinder 14 is held at a position to be engaged with the engaging portion 13 so that the brake cylinder 14 is rotated integrally with the spool shaft 2 via the cylinder shaft 7 so that the spool shaft 2 is rotated. The brake 12 is drag-braked, and the tip of the return actuating body 31 is held outside the turning locus of the kick portion 26 of the returning body 27 provided on the handle shaft 22 on the rear surface of the drive gear 25, and the regulating body 34 is engaged. The projection 33 engages with the engaging portion 36 of the return actuating body 31 and is held in the restricting position, and the restricting projection 32 blocks the forward rotation of the operating member 16 and the winding force causes the cylindrical shaft 9 to rotate. The twisted ridge 5 is prevented from coming off the engaging hole 13.

Next, in order to switch from the drag operating state to the spool free state, the operation lever 20 is rotated rearward as shown in FIG. 3, and the return piece 19 rotates the return operating body 31 and its engaging portion. 36 disengages from the engaging projection 33 of the restricting body 34 and releases the restricting position of the restricting body 34, and at the same time, the operating piece 18 tilts the operating member 16 forward against the spring 15 and engages with the annular groove 4. The mating yoke 17 slides forward on the cylinder shaft 7, and the twisted ridge 5 is disengaged from the engaging portion 13 of the braking cylinder 14, so that the engagement between the spool shaft 2 and the braking cylinder 14 is separated, and the spool The shaft 2 is rotatable and is in a spool-free state. Further, the rotation of the return actuating body 31 by the return piece 19 causes the tip of the return actuating body 31 to be held within the rotation locus of the kick portion 26 of the return body 27. However, when the spool shaft 2 rotates in the reverse direction in the spool free state, the click teeth 9 of the second braking cylinder 10 that rotates integrally with the cylinder shaft 7 generate a sound by the engagement with the click claws to notify the reverse rotation.

To switch the spool free state back to the drag operating state again, the handle shaft 22 is rotated counterclockwise in FIG. 1, which is the fishing line winding direction, and the kick portion 26 of the return body 27 is rotated. The rotation of the operating lever 20 causes the operating lever 20 to return to the upright position of the drag operating state and operate by engaging with the tip of the return actuating body 31 and rotating it until it exceeds the dead point of the spring 21. The member 6 is pulled rearward by the ridge 15 and slides backward on the cylinder shaft 7, and the twisted ridge 5 is guided in the rearward direction while rotating in the guide groove 11, and its tip is smoothly and reliably engaged. The engaging portion 36 of the return actuating body 31 engages with the restricting projection 32 of the restricting body 34 at the same time that the engaging part 36 of the returning actuating body 31 is engaged with the part 13 and the tip of the returning actuating body 31 is also returned and held outside the rotation locus of the kick part 26. The regulation body 34 together The operation member 16 is prevented from rotating forward by holding it in place.

When the spool shaft 2 reversely rotates in the drag operating state, the second braking cylinder 10 rotates and the click teeth 9 sound by the click claws to notify the reverse rotation. By adjusting the pressure contact force with respect to the braking cylinder 10, the drag braking force when the spool is free can be finely adjusted. In each of the above embodiments, as a means for switching and returning from the drag-free state to the drag operating state, a case where the return body provided on the handle shaft is used to automatically return by the turning operation of the handle Although illustrated, a manual switching means for returning the operating lever to the front may be used.
