JPH01191630A - Speed changing apparatus of both bearing type reel for fishing - Google Patents

Abstract

PURPOSE:To provide the title apparatus having good winding-up efficiency, by changing the winding-up speed of the apparatus into a high or low speed by the manually rotating operation of an adjusting lever or the manually rotating operations of both the adjusting lever and an adjusting grip. CONSTITUTION:An adjusting lever 15 or both the adjusting lever and an adjusting grip 18 are rotated to relatively move a braking cylinder 9 and a pressing cylinder 11 with respect to each other in a direction of the axis thereof, thereby bringing the braking cylinder into pressure contact with a low speed abrasion braking member 8 to abrasively connect the low speed abrasion braking member with a low speed driving gear 7 or bringing the pressing cylinder into pressure contact with a high speed abrasion braking member 13 to abrasively connect the high speed abrasion braking member with a high speed driving gear 12. Thus, the rotation of the low speed driving gear is transmitted to a low speed gear 3 on a spool shaft 2 to perform the low speed winding-up of a fishing line or the rotation of the high speed driving gear is transmitted to a high speed gear 4 on the spool shaft to perform the high speed winding-up of the fishing line. A drag adjusting operation is carried out by each rotation of the adjusting handle 19 or adjusting grip 18.

Description

[Detailed description of the invention]

[Field of Application on I-Beam] The present invention relates to a transmission device for a double-bearing reel for fishing.

[Conventional technology]

It was developed as a fishing reel that changes speed to high or low by switching the high-speed and low-speed drive gears on the handle shaft and the gears on the spool shaft in which these gears mesh according to the winding load of the fishing line.
- Automatic transmission system seen in Publication No. 5238 and Utility Model No. 6
A manual transmission system disclosed in Japanese Patent No. 0-182779 is known. [Problem M to be solved by the invention] The conventional automatic transmission method may seem convenient at first glance, but since the transmission is automatically changed depending on the relationship between the drag setting force and the tension of the fishing line, the angler can easily change the speed regardless of the reeling load. There is an inconvenience that it is not possible to freely switch between high speed and low speed depending on the winding conditions and fishing method, etc., and in both cases of high speed and low speed switching, the winding is increased by the amount that the high speed gear and the low speed gear are subject to frictional resistance and spin idly. There are defects that reduce efficiency. In addition, with the latter manual speed change, the angler can switch between high and low speeds according to his will, but in the conventional method, the high speed drive gear and low speed drive gear on the handle shaft are switched by sliding with a cam. When meshing with the high-speed and low-speed gears of the spool shaft, the tooth profile is scratched, making it impossible to switch smoothly under load, and since there is no drag mechanism, drag braking is not possible, and the speed change mechanism is also large. There are defects such as It is an object of the present invention to provide a transmission device for a double-bearing fishing reel that improves reeling efficiency by taking advantage of the advantages of manual transmission while improving the deficiencies of the conventional manual switching system.

[Means for Solving the Problems 1] In order to achieve the above object, the present invention provides a spool shaft with a low speed gear and a high speed gear, and a low speed drive gear that meshes with the low speed gear and a high speed gear that meshes with the high speed gear. Either one of the high-speed drive gears is rotatably fitted to the handle shaft so as to transmit power by a friction braking member, and a brake cylinder that presses the friction braking member is moved only in the axial direction about the handle shaft. The other driving gear is rotatably fitted to the outer circumferential surface of the brake cylinder so as to transmit power by a friction braking member, and a pressing body is attached to a threaded portion formed at the rear of the brake cylinder. are screwed together so that the front part of the pressing body faces a friction braking member provided on the brake cylinder, and the rear end of the suppression cylinder is engaged freely in the axial direction with an adjustment lever rotatably fitted on the handle shaft. , an adjustment knob is screwed onto the handle shaft at the rear of the adjustment lever, and the drag lever can be adjusted by setting the drag lever with the adjustment knob in consideration of fishing conditions in advance, and then adjusting the drag lever while fishing. and gear shifting operations are suitable for performing with an adjustment lever. The rear end surface of the brake cylinder can also be brought into contact with the front surface of the adjustment lever, and in this case, both the adjustment lever and the adjustment handle are operated together for the switching operation. In addition, the press cylinder is fitted onto the brake cylinder so that it can rotate without being screwed together, and one of the friction braking members provided on the press cylinder and the brake cylinder is formed into a cam surface so that they engage with each other. In this case as well, the switching operation involves operating both the adjustment lever and the adjustment handle. Further, it is preferable to interpose a spring between the adjustment lever and the adjustment handle or between the rear side of the friction braking member fitted on the handle shaft and the front of the brake cylinder, as this allows smooth adjustment of the drag force. However, this spring is not necessarily required. Furthermore, the handle shaft can be formed into a hollow shaft and fitted onto a protruding fixed shaft to form a cantilever type. [Operation] The present invention operates by rotating the adjustment lever or the adjustment handle and moving the brake cylinder and the pressing cylinder relative to each other in the axial direction, so that the brake cylinder presses the low-speed friction braking member to the low-speed drive gear. The rotation of the low-speed drive gear is transmitted to the low-speed gear on the spool shaft by friction-connecting the high-speed drive gear by pressing the high-speed friction braking member with a press cylinder to the low-speed gear on the spool shaft. The device performs winding and high-speed winding by transmitting the rotation of the high-speed drive gear to the high-speed gear on the spool shaft, and the drag adjustment operation is performed by turning the adjustment handle or knob individually. This is done by moving.

【Example】

To explain the embodiment of the present invention with reference to the drawings, the spool 1
A large-diameter low-speed gear 3 and a small-diameter high-speed gear 4 are attached to the spool shaft 2 via a clutch mechanism.
A low-speed drive gear 7 that meshes with the low-speed gear 3 is rotatably fitted to a handle shaft 6 which is detachably connected to the handle shaft 6 and has an occluded circular cross section and has a ratchet 5 fixed to its tip. A low-speed friction braking member 8 is provided in the rear concave portion of the low-speed drive gear 7, and is configured to connect the handle shaft 6 and the low-speed drive gear 7 by frictional force. A brake 8 is mounted on the handle shaft 6 at the rear of the low-speed friction brake member 8.
29 is engaged so as to be movable only in the axial direction, a pressing body 11 is screwed into the threaded portion 10 formed at the rear of the brake tube 9, and the high speed gear 4
A high-speed drive gear 12 meshed with the high-speed drive gear 12 is rotatably fitted, and a high-speed friction braking member 13 frictionally connects the brake cylinder 9 and the high-speed drive gear 12 in the rear recessed portion of the high-speed drive gear 12. It is formed to do so. The front end surface of the pressing body 11 faces the high-speed friction braking member 13 so as to be in pressure contact therewith, and the engagement protrusion 14 protruding from the rear end of the pressing body 11 is rotatable around the handle shaft 6. The pressing body 11 and the adjustment lever 15 are configured to freely engage in the locking recess 16 of the fitted adjustment lever 15 in the axial direction, so that the pressing body 11 and the adjustment lever 15 rotate integrally. An adjustment knob 18 is screwed into the rear part of the adjustment lever 15 via a plate spring 17 so as to be able to move forward and backward, and a handle 19 is fixed to the rear end of the handle shaft 6. A loosening prevention device 21 is provided which engages with the uneven portion 20 provided on the inner circumferential surface and moderates its rotation. With this structure, after setting the range of the drag force with the adjustment handle 18 in advance, the adjustment lever 15 can be adjusted.
When the adjustment knob 18 is rotated to the Low side in FIG.
The pressing force of the adjustment lever 15 is applied to the pressing body 11 by the spring 17. It acts on the brake cylinder 9 and the low-speed friction braking member 8 to frictionally connect the low-speed drive gear 7 with the handle shaft 6, rotates the low-speed gear 3 meshed therewith, and rotates the spool 1 at low speed. Normally, when adjusting the drag force in this state, rotating the adjustment lever 15 further toward the Low side will make the drag force stronger, and conversely, rotating it toward the High side will weaken the drag force, but the adjustment operation will This can also be done by rotating the adjustment handle 18. Next, when switching from low speed winding to high speed winding, when the adjustment lever 15 is rotated to the )ligH side, the pressing body 1
1 presses the high-speed friction braking member 13 to frictionally connect the high-speed drive gear 12 to the handle shaft 6 via the brake f719, while the pressing dimensions of the low-speed friction braking member 8 and the adjustment lever 15 are as shown in FIG. As shown in the figure, the winding speed is shortened from Q to Q', the frictional coupling force of the low-speed drive gear 7 is minimized, and the state is switched to the high-speed winding state. The drag force during high-speed winding can also be adjusted by operating the adjustment lever 15 in the same manner as described above. The embodiment shown in FIG. 5 is a case in which the handle @6 is formed into a hollow shaft and fitted onto a fixed shaft 23 protruding from the frame 22 so as to be cantilevered. Further, the embodiment shown in FIG. 6 is a modification in which the rear end of the brake cylinder 9 in the embodiments shown in FIGS. 1 to 4 is brought into contact with the front surface of the adjustment lever 15. For switching, both the adjustment lever 15 and the adjustment knob 18 must be operated. That is, in the low-speed winding state shown in FIG.
It acts on the low-speed drive gear 7 through the low-speed friction braking member 8 and is frictionally coupled to the handle shaft 6. At this time, the adjustment lever 15 is rotated so that the tip surface of the pressing body 11 is connected to the high-speed friction braking member. High speed drive gear 1 is moved in the direction from 13 to
The frictional coupling force of 2 is minimized to reduce the idling resistance force. Next, when switching to high-speed winding, rotate the adjustment handle 18 to reduce the drag of the low-speed drive gear 7, and rotate the adjustment lever 15 to strengthen the drag of the high-speed drive gear 12. Can be done. The drag force at low speeds or high speeds is adjusted by individually rotating the adjustment knob 18 or the adjustment lever 15. In the embodiment shown in FIG. 7, instead of screwing the pressing body 11 to the brake cylinder 9 in the previous embodiment, either the front surface of the pressing body 11 or the rear surface of the high-speed friction braking member 13 is formed into a cam 24. At the same time, the other is formed in the protrusion 25 so as to be engaged with it and pressed into engagement. In each of the above embodiments, a low speed gear 3 is provided on the inside of the spool shaft 2, and a high speed gear 4 is provided on the outside, and the low speed drive gear 7 and the high speed drive gear 12 of the handle shaft 6 are meshed with each other. It is also possible to provide a high-speed gear 4 on the inside of the spool shaft and a high-speed gear 3 on the outside, and the spring 17 is provided between the rear side of the low-speed friction braking member 8 and the front of the brake cylinder 9. There is no problem in including it or omitting it. Effects of the Invention In the present invention, the angler can switch to high or low speed by manually rotating the adjustment lever or by manually rotating both the adjustment lever and the adjustment knob. You can switch to high or low speed depending on the angler's reeling conditions and fishing method, such as when you want to switch from low speed reeling to high speed reeling when the fish does not hook or the fish runs away midway through. The drag force can be adjusted freely during high-speed winding or low-speed winding by rotating the adjustment lever and adjustment knob, and by operating the adjustment lever and adjustment handle, the drive gear can avoid spinning due to frictional resistance. Therefore, winding efficiency is good, and the transmission mechanism itself has excellent features such as being more compact than conventional manual transmission mechanisms.
