Description

[Detailed description of the invention] In a double-bearing reel for fishing, the spool, which is connected to the drive shaft with the handle by the clutch, is connected to the clutch lever.
It is already known that the spool is rotatably separated by the action of the handle, and the separated spool is automatically connected to the drive shaft by the rotation of the handle.

However, among the conventional systems, the system in which the kick pin of the drive shaft rotates the pair of left and right kick levers to return the clutch lever to the clutch engagement position, as seen in Japanese Utility Model Publication Nos. 53-31274, has a complicated mechanism. The large number of parts hinders weight reduction, which is an important requirement for this type of reel, and there is also a drawback that frictional resistance is large when operating the clutch lever to disengage the clutch or when operating the kick lever.

Further, the embodiments shown in FIGS. 1 to 4 of Japanese Utility Model Publication No. 30-6179 also have the same defects as those described above and require a high degree of precision, and the embodiments shown in FIGS. 4 to 7 Since it is a one-way type with a single kick lever, it has a defect that the clutch cannot be separated reliably depending on the position of the kick pin on the drive shaft.

Furthermore, as seen in Japanese Patent Application Laid-open No. 51-3990, there is also a known method in which an annular member having a kick pin is rotatably supported on a drive gear or fitted onto a drive shaft, Because it can swing freely, it has a defect that it generates unpleasant vibrations or impact noises when casting or driving the handle.

The present invention is an attempt to improve these defects, and includes a pinion that engages with the gear of the drive shaft, which is removably engaged with the spool shaft, and a clutch plate that engages with the pinion, which is pivotally supported on the reel side plate. At the same time, a flat plate clutch lever having a clutch plate actuating protrusion on the back surface of the clutch plate and having a fork-shaped distal end branched into long and short parts is provided so as to be slidable inwardly, and one of the short branched pieces is provided with a spring. The other long branched piece has a locking protrusion and a guide surface in which a boss protruding from the inner plate engages, and a guide surface connected at right angles thereto. The tip of the arm rod is provided with an engagement notch, and is rotatably pivoted only outwardly on the inner plate on the outside of the locking protrusion. An actuating piece having a locking part formed in the middle part of the outer side is pivotally supported, and the actuating piece is pulled and biased to one side of the locking protrusion by a spring so that the locking part can be freely locked to the locking protrusion, and A kick pin is provided on the surface of the anti-reverse rook so that it collides with the tip of the actuating piece when the clutch lever is in the inward position, and when the actuating piece is pushed and moved by the kick pin, the engaging part of the actuating piece is The gist is that the locking protrusion is locked and moved in a direction in which the engagement notch moves away from the boss.

To explain the embodiment of the present invention with reference to the drawings, the spool 1
A pair of left and right reel side plates 3, 4 which rotatably support a spool shaft 2 to which a spool shaft 2 is fixed are an outer plate 5.6 and an inner plate 7, 8, respectively.
On one side of the spool shaft 2, an engaging part 9 having an occluded circular cross section is formed, and on the outside of the engaging part 9, a small diameter shaft part 10 has one end fitted into the retaining part 9. A pinion 12 having a coupling portion 11 is slidably fitted therein.

The pinion 12 is connected to a drive shaft 1 which is pivotally supported on the reel side plate 3.
The upper end of the clutch plate 15, which meshes with the driving gear 14 fixed to the pinion 3 and further engages the pinion 12, is connected to the inner plate 7.
The clutch plate 15 is supported by a shaft 17 on a support frame 16 provided on the shaft 17, and a spring 18 screwed onto the shaft 17 springs the clutch plate 15 so that the connecting portion 11 of the pinion 12 is connected to the retaining portion 9. ing.

Further, a clutch plate operating protrusion 19 is provided on the rear side of the clutch plate 15.
A clutch lever 20 having a long and short bifurcated tip is provided to be slidable in the radial direction via a long hole 21 bored in the clutch lever 20 and a pin 22 protruding from the inner plate 7. ,
The operating portion 23 at the outer end protrudes from the knoll side plate 3.

At the base of the long branch piece 24 of the clutch lever 20, there is a guide surface 2 that slides into contact with a boss 25 protruding from the inner plate 7.
6 and an engagement notch 27 that is connected to the boss 25 at right angles thereto, and a locking protrusion 28 is provided at the tip, and a locking protrusion 28 is provided at the tip of the other short branch piece 29. A spring 30 is attached to pull and bias the clutch lever 20 outward and to the side of one side of the short branch.

An arm rod 32 with an actuating piece 31 pivotally supported at its tip is pivotally attached to the inner plate 7 on the outside of the branch piece 24, and the arm rod 32 is restricted by a stopper 33 so that it can only rotate outwardly in a counterclockwise direction. Further, the tip of the actuating piece 31 extends on the peripheral surface of the anti-reverse rook 34 fixed to the rear side of the drive gear 14, and is stretched between its base end and the arm rod shaft attachment part. The locking protrusion 28 is rotated counterclockwise by the spring 35.
A locking portion 31 ′ provided at a midway portion of the outer side of the actuating piece 31 is formed so as to be locked to the locking protrusion 28 . The engagement notch 27 is configured to lock and move in a direction away from the boss 25.

On the other hand, a pair of kick pins 36 and 36 are protruded from the surface of the anti-reverse rook 34 on the same circumference.
．． The distance from the center of the clutch lever 20 is set so that the guide surface 26 of the clutch lever 20 does not collide with the actuating piece 31 even if the clutch lever rotates in the outwardly drawn position where the guide surface 26 is in sliding contact with the boss 25, and the clutch In the inwardly pushed position of the clutch lever where the engagement notch 27 of the lever 20 is engaged with the boss 25, the rotating kick pin 36 is protruded in such a position that it collides with the tip of the actuating piece 31. Further, the reverse rotation preventing rook 34 is provided with a claw 37 which can be freely engaged and detached as is known in the art to prevent reverse rotation.

Since the embodiment of the present invention is constructed as described above, in order to make the spool 1 freely rotatable, when the clutch lever 20 is slid inwardly against the spring 30 with the operating portion 23, the clutch actuating projection is pressed. The part 19 rotates the clutch plate 15 against the spring 1B, disengages the pinion 12 from the engaging part 9 of the spool shaft 2, and makes the spool 1 rotatable. At the same time, the actuating piece 31 rotates the locking protrusion 28 It rotates as it moves, and the guide surface 2
6 is disengaged from the boss 25, the engagement notch 27 is engaged with the boss 25, and the clutch lever 20 is held in that position.

Next, in this state, when the bundle rotates the drive shaft 13 in the fishing line winding direction, the reverse prevention rook 34 rotates, the kick pins 36 and 36 press the actuating piece 31 outward, and at the same time lock the locking protrusion 2B. As a result, the clutch lever 20 is also pushed outward to disengage the engagement notch 27 from the boss 25, and the clutch lever 20 is pulled outward by the spring 30 and returned to the outwardly drawn position.

When the clutch lever 20 returns to the outwardly pulled out position in this way, the clutch plate 15 of the clutch operating protrusion 19
Since the pressing action on the spool shaft 2 is released, the clutch plate 15 connects the pinion 12 to the engaging portion 10 of the spool shaft 2 by the spring 18, and the rotation of the drive shaft 13 is performed by the drive shaft 14,
The fishing line is transmitted to the spool 1 via the pinion 12 and the spool shaft 2, and the fishing line is wound thereon.

Note that when the clutch lever 20 is pressed and the kick pin 36 is at a position that just blocks the actuating piece, the actuating piece 31 is supported by the kick pin 36 and only the clutch lever 20 is locked in the inwardly pushed position. .

However, the actuating piece 31 supported on the kick pin 36 like a lever is rotated by the rotation of the kick pin 36 when winding the fishing line.
First, the clutch lever 20 is locked by the locking protrusion 28, and then the rotation of the kick pin returns the clutch lever 20 as described above.

In this invention, the locking protrusion provided on the clutch lever is locked to the mid-way latch of the actuating piece that is pivotally supported at the tip of the arm rod, and the tip of the actuating piece is rotated by the rotating action of the kick pin protruding from the reverse prevention rook. When pushing sideways, the locking part of the actuating piece forcibly moves the locking protrusion of the clutch lever in the direction in which the engagement notch moves away from the boss, so the clutch lever can be moved without being affected by the position of the kick pin. The clutch lever can be smoothly and reliably locked in the inwardly pushed position to disengage the clutch, and the locking part moves automatically without sliding against the clutch lever due to the rotating action of the drive shaft. The clutch can be engaged by returning the clutch to the outwardly drawn position accurately and reliably, and in this case, the sliding movement of the clutch lever is guided by the actuating piece and is performed smoothly without rattling, and the arm lever and actuating piece are The load on the shaft support is small, so it does not suffer from the defects of conventional sliding systems, such as wear on the sliding surface, running out of oil, and problems with energizing, and has excellent features such as a simple configuration and a small number of parts. It has practicality.
