Abstract

PURPOSE:To obtain a drag apparatus capable of fully exhibiting the drag performance even in winding operation by braking an internal gear with a braking gear according to a prescribed drag force and forcing a planetary gear to revolve around an axis while rotating on its own axis in winding operation. CONSTITUTION:When a handle cylinder 11 is rotated with a handle 9 in the direction to wind a fishing line, a sun gear 10 integrated with the cylinder is rotated. Since an internal gear 15 is braked with a brake gear 19 according to a prescribed drag force, a planetary gear 14 is forced to revolve around an axis while rotating on its own axis to rotate the driving gear 8 in the direction to wind the fishing line. The fishing line is wound on a spool 3 driven by a pinion 5 and a spool shaft 4. When the load on the spool is increased in a wound state, the driving gear is stopped, the planetary gear 14 is rotated on its own axis without revolving around an axis to rotate the internal gear 15 and the brake gear 19 is forced to slip and rotate against the drag force.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field 1) The present invention relates to an improvement of a drag device for a fishing reel.

[Prior art 1] As a drag device for a fishing reel,
A method of installing the handle on a drive shaft [-] as seen in Japanese Utility Model Publication No. 374, and a method of installing the handle on a spool shaft as shown in Japanese Utility Model Application No. 62-204476 are known.

[Problem to be solved by the invention M1] In the former conventional method, the drag adjustment knob rotates together with the drive shaft, so it is not possible to adjust the drag while winding the fishing line, and the size of the drag adjustment knob is also restricted. There is also a drawback that the adjustment operation cannot be done quickly and smoothly, and although the latter method eliminates these defects, the spool shaft is pressed in the axial direction and rotates with the pressing force applied to the bearing, making it difficult to rotate. At the same time, the spool becomes heavier due to the side of the drag machine, resulting in poor rotational performance during casting.Moreover, since it is a mechanism that has both a drag function and a clutch function,
There are problems such as the inability to operate the clutch independently and poor operability.

Therefore, in order to improve both of these deficiencies, we directly connected the l drive teeth 11 to the drive shaft with a handle only when winding the fishing line, and provided a drag device on a shaft separate from the drive shaft and spool shaft to connect the pinion of the spool shaft. It is known from Japanese Patent Laid-Open No. 58-5126 that the brake is connected with +'#'1 () so that braking is performed only when the spool is reversed.

However, with this method, even if the fish pulls more than the set drag force while winding the fishing line, the winding action is prioritized and directly connected, so the drag action does not work according to the tension caused by the fish's pull, causing the fishing line to break. There is a point.

In view of these current circumstances, the present invention utilizes the YI Hoshida + LJ mechanism to not only improve the deficiencies of the conventional system, but also to fully utilize the set drag performance especially during winding operations. It is an object of the present invention to provide a drag device that can reliably prevent fishing lines from being cut.

[Means for Solving the Problems 1] In order to achieve the above object, the present invention provides a mechanism in which a handle rotation cylinder provided with a sun gear is rotatably fitted to a support shaft protruding outward from a frame of a reel side plate. It is attached, meshes with the pinion of the spool shaft, and rotates around the support shaft! I
A planetary gear is pivotally supported on the lφ moving tooth 11 (provided so as to be able to
the planetary gear is meshed with the sun gear and an inner gear provided to rotate around a support shaft; 1)
The outer teeth provided on the outer periphery of the η-oriented side "heavy shaft 11f" are engaged with the brake teeth 1 (supported by the reel side plate and freely adjustable by a drag adjustment knob, and furthermore, a reverse rotation prevention mechanism is provided on the handle rotation cylinder. It was established.

The drive gear d9J may be rotatably fitted directly to the support shaft, but it may also be rotatably fitted to one handle rotation 11 provided with a sun gear.

Further, the inner gear having the outer teeth is the reel side plate or the 1
It can be supported on a 1μ toothed shaft or on a handle rotation cylinder so as to rotate around a support shaft.

[Operation] According to the present invention, when the handle rotation tube is rotated in the fishing line winding direction by the handle, the sun gear integrated with the rotation tube rotates, and the inner gear rotates according to the drag force preset by the braking tooth width. Since it is stopped, the planetary gear revolves while rotating, and its revolving action causes the drive J gear to rotate in the fishing line winding direction, and the fishing line is wound onto the spool via the pinion and the spool shaft.

In such a winding state, when the load on the spool increases and the preset drag of the brake gear is rotated once, the drive gear, which is in mesh with the pinion once, is turned. FIJ m 'I (is fixed and the planetary gear does not revolve, but rotates the inner tooth IC to control 1g) The gear slips and rotates against the drag force, so even if you turn the handle and operate it, there is no drag. is in a slip state.

In addition, when the load on the spool exceeds the set drag force of the braking gear due to pulling out the fishing line while the handle is not being wound up, the drive gear rotates in the opposite direction in the direction of feeding out the fishing line, and the planetary tooth -+l+ also revolves in the same direction. . However, since the sun tooth TL (does not reverse rotation due to the anti-reverse mechanism, there is play IJ,
The tooth -1f rotates due to the above-mentioned revolution action and becomes the inner tooth muff.
, the braking gear slips and rotates against its drag force, and the spool is full like a drag force and the fishing line is paid out.

[Embodiment 1] To explain an embodiment of the present invention with reference to the drawings, a spool shaft 4 rotatably supported by the reel side plates 1 and 2 and to which a spool 3 is fixed is provided with a pinion 5 that can be freely engaged and detached, as is known in the art. A fixed or rotatable support shaft 7 protrudes outward from the flare lx 6 of the reel side plate 1, and an 11μ moving tooth 8 that engages with the pinion 5 is rotatably fitted into the base of the fixed or rotatable support shaft 7. On the outside, there is a handle 9 at the outer end and a sun gear [0] at the inner end.

FIG. 5 shows an embodiment in which the inner gear 15 is rotatably supported on the drive gear 8, and FIG. 6 shows an embodiment in which the inner gear 15 is rotatably supported on the handle rotation barrel 11. .

In the embodiment shown in FIG. 7, the first drive gear 8 is directly supported by the shaft 7.
This is a case where the handle rotation cylinder 11 is rotatably fitted instead of being fitted into the handle rotation cylinder 11.

Therefore, after setting the drag of the brake tooth center 19 to a predetermined value using the drag adjustment handle 21, when the handle rotation tube 11 is rotated clockwise using the handle 9 as shown by the solid line arrow in FIG. 3, which is the fishing line winding direction, This and the sun tooth-1 (

[Effects of the Invention] By utilizing a planetary gear mechanism, the drag device of the present invention fully exhibits the set drag performance not only when reversing the spool, but especially when winding up the fishing line, thereby preventing the dragee from slipping. Therefore, it is possible to reliably prevent the fishing line from breaking during fishing operations, and the fishing operations can be carried out easily and smoothly, and unlike conventional methods, the handle operation becomes heavy and the casting performance deteriorates. It has an excellent feature that it does not cause the drag to fall, and it is easy to adjust the drag while fishing.
