Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a double bearing reel clutch mechanism, and more particularly to an improved clutch mechanism without dead points.

Conventional clutches in this kind of double bearing shaft type reel disconnect the power transmission path by pushing or rotating the clutch lever, allowing the spool to rotate freely for casting, and after casting, the fishing line is spooled. When the clutch is returned to its original position for winding, it is done by rotating the handle.

However, in order to release the clutch, two or more switching pins for releasing the clutch are attached to a rotary plate, such as a non-return gear, which is driven and rotated by the rotation of the handle.
A configuration in which four strands are fixed in an upright manner is adopted.

Therefore, when releasing the clutch, you have to turn the handle 1/4 to 1/2 turn before the clutch can be released.
It required a lot of play and lacked practicality.
Moreover, in the case of the clutch mechanism described above, when an attempt is made to turn the clutch OFF by pushing the clutch lever, a so-called dead point occurs where the clutch cannot be turned OFF, making it inconvenient to operate the clutch. It had a problem that made it feel like this.

Therefore, in view of the above-mentioned circumstances, the inventor of the present invention has devised a system that can quickly change the clutch OFF state to the clutch ON state by a slight rotation of the handle, and can also turn the clutch OFF in any state. A clutch mechanism without a dead point has been developed that can be used to lock the clutch, and its structure was completed by using a non-return pawl in the non-return mechanism.

The double bearing shaft reel clutch mechanism of the present invention, which aims to achieve the above-mentioned object, has a pinion gear slidably attached to the spool shaft of a spool horizontally supported across the left and right side frames, and the pinion gear is attached to the handle shaft. The pinion gear is engaged with a main gear that rotates integrally with the spool shaft, and the pinion gear is connected to and detached from the spool shaft in conjunction with the pushing of a clutch lever attached to the side frame, and a clutch hooking pin is fixed to the clutch lever. It fits into the L-shaped engaging groove formed on the board, and furthermore, the horizontal side of the L-shaped switching pawl is pivoted to the clutch lever so that it can swing freely, and the vertical side touches the vertical receiving part of the clutch lever. The claw portion of the non-return claw is engaged and can be pivoted in one direction, the tip of the switching claw is pivotally supported on the board, and the claw part of the non-return claw is automatically engaged and disengaged by rotation of the non-return gear. It is characterized in that it can be freely engaged and detached from the engaging portion on the opposite side.

In the present invention, the form of the non-return pawl that engages and disengages from the non-return gear as the gear rotates is such that a guide plate formed in a shape is fixed to the pawl side of the non-return pawl, and the tip of the guide plate is fixed to the pawl side of the non-return pawl. When the non-return gear rotates in the forward direction, the claw of the non-return pawl is pushed out in a direction that does not engage the teeth, and when the non-return gear rotates in the reverse direction, the claw part There are two types: one in which the claw of the non-return claw is pulled in the direction in which it engages with the teeth of the non-return gear, and the other in which the claw of the non-return claw is elastically biased in the direction in which it engages with the teeth of the non-return gear using an elastic member (non-return claw spring). can be mentioned. Note that in the former case described above, no back-stop sound is generated, and in the latter case, a back-stop sound is generated.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a side frame constituting the reel body, and the side frame 1 is formed by a substrate 1-a, a cover 1-b, and a spool ring 1-c. It is formed into a hollow shape,
Bearing 2 attached to left and right spool rings 1-c
A spool shaft 4 of the spool 3 is rotatably supported on a horizontal shaft, and a power transmission mechanism and a clutch mechanism for rotating the spool 3 are built inside the side frame 1.

A pinion gear 5 is attached to the spool shaft 4 in the side frame 1 so as to be slidable along the axial direction, and the pinion gear 5 is connected to a handle shaft 6 rotatably supported on the base plate 1-a. The pinion gear 5 is engaged with a main gear 7 that rotates integrally with the spool shaft 4, and the pinion gear 5 is configured to be able to engage and disengage from the spool shaft 4. When the pinion gear 5 is engaged with the spool shaft 4, the rotation of the handle is the main rotation. It is transmitted to the spool 3 via the gear 7 and the pinion gear 5, and when the pinion gear 5 comes off the spool shaft 4, the spool 3 rotates freely.

The mechanism for engaging and disengaging the pinion gear 5 from the spool shaft 4, the so-called clutch mechanism, includes a passive plate 9 that is fitted into and engaged with an annular groove 8 carved on the circumferential surface of the pinion gear 5, and moves the passive plate 9 up and down. Clutch lever 10, clutch hook pin 11 for preventing the clutch lever 10 from returning, clutch hook pin 11
It is composed of an L-shaped engaging groove 12 for engaging, an L-shaped switching claw 13, and a non-return claw 14.

To explain the clutch mechanism in more detail below, the passive plate 9 which integrally engages and supports the pinion gear 5 has its left and right sides connected to the base plate 1-a and the cover 1-a.
The support rod 15 is vertically movably fitted to a support rod 15 that extends over the upper surface of the passive plate 9, and a coil spring 16 is elastically mounted between the upper surface of the passive plate 9 and the cover 1-b, so that the passive plate 9 is always downwardly moved. In other words, the pinion gear 5 is pressed in the direction in which it engages with the spool shaft 4. The clutch lever 10 has a bifurcated portion on the opposite side of the operating portion 10-a, and a raised portion 17 is integrally provided on the bifurcated piece 10-b, and a guide groove 18 is cut out in the middle of the bifurcated piece. The guide groove is fitted into a guide rod 19 which is fixed upright on the board 1-a, and is bent in the clutch lever 10 to connect the vertical receiving part 20 and the protrusion 21 on the board 1-a. A tension spring 22 is stretched across.

Further, a clutch hooking pin 11 is provided on the back side of the tip of one of the forked pieces 10-b of the clutch lever 10.
is fixed, and its clutch hook pin 11
is fitted into the L-shaped engagement groove 12 formed on the board 1-a, and when the clutch lever 10 is pushed, the clutch hook pin 11 is fitted into the guide groove 12- of the L-shaped engagement groove 12.
a, and enters the engagement groove 12-b continuous with the groove 12-a, stopping the return of the clutch lever 10 and maintaining the clutch lever 10 in the pushed state.

Furthermore, the clutch lever 10 has an L-shaped switching pawl 13.
The horizontal side portion 13-a of the clutch lever 10 is pivotably attached to the clutch lever 10 by a set screw 23, and the vertical side portion 13-b is pivotally attached to the clutch lever 10.
At the same time, the vertical side portion 13-b is elastically biased by a switching pawl spring 24 wound around a set screw 23 in the direction of abutting and engaging with the vertical receiving portion. There is. Therefore, the L-shaped switching pawl 13 can swing freely against the elastic force of the switching pawl spring 24 in the direction in which the vertical side portion 13-b moves away from the vertical receiving portion 20.

The side end of the vertical side portion 13-b of the L-shaped switching pawl 13 is configured to be able to engage and disengage from the engaging portion 14-b of the non-return pawl 14.

The non-return claw 14 is bent into a substantially dogleg shape, with a claw portion 14-a that engages with the non-return gear 25 on one side and a vertical side portion 13-b of the L-shaped switching claw 13 on the other side. An engaging portion 14-b is formed, and the center portion of the non-return pawl 14 is fixed to the board 1-b with a set screw 26.
A shaped guide plate 27 is fixed to the claw portion 14-a side, and its tip is attached so as to clamp the peripheral edge of the non-return gear 25. Therefore, when the non-return gear 25 rotates in the forward direction, the claw portion 13-b is pushed away from the teeth, and when the non-return gear 25 rotates in the opposite direction, the claw portion 13-a is pushed away from the teeth. It is something that is attracted to the direction that engages with the part.

Note that the above-mentioned guide plate 2 is used as a means for engaging and disengaging the claw portion 14-a of the non-return claw 14 from the non-return gear 25.
In addition to the form according to 7, as shown in FIG.
Of course, it is also possible to employ a structure in which the claw portion 14-a is biased in the direction of engagement with the non-return gear 25.

Next, to explain the operation of the clutch mechanism described above, first, when the operating part 10-a of the clutch lever 10 is pushed in the clutch ON state shown in FIG. The clutch hook pin 11 located on the board 1-
Guide groove part 12-a of the L-shaped engaging groove 12 opened in a
, and enters the engagement groove 12-b which is continuous with the groove 12-a, and the clutch lever 10 is held in the pressed state.

At this point, the pinion gear 5 slides in the direction in which it disengages from the spool shaft 4 due to the action of the passive plate 9 which is pushed upward by the raised portion 17 as the clutch lever 10 is pushed. The clutch is in an OFF state where it can freely rotate. In this state, when the handle 29 is rotated in the fishing line winding direction (normal rotation direction), the inclined part of the non-return gear 25, which is driven and rotated by the rotation of the handle 29, causes the claw part 14-a of the non-return claw 14 to be moved outward. As a result, the non-return pawl 14 swings around the set screw 26, and the engaging portion 14-b of the non-return pawl 14 comes into contact with the vertical side 13-b of the L-shaped switching pawl 13, thereby locking the clutch. The lever 10 is swung, and the clutch hook pin 11 is inserted into the engagement groove 12.
-b, and the clutch lever 10 returns to its original state by the tensile force of the tension spring 22. (See Figure 5) At this time, the pinion gear 5 is slid by the passive plate 9 which is urged downward by the elastic force of the coil spring 16, and engages with the spool shaft 4 to drive the spool 3. clutch rotated
It will be in the ON state. (See Fig. 3) Fig. 6 shows a case where the clutch lever 10 is pushed with the pawl 14-a of the non-return pawl 14 meshing with the valley of the non-return gear 25; Vertical side 1 of attached L-shaped switching claw 13
3-b moves forward without coming into contact with the engaging portion 14-b of the check pawl 14, and the clutch is turned OFF.

FIG. 7 shows the clutch lever 10 being pushed with the pawl 14-a of the non-return pawl 14 resting on the teeth of the non-return gear 25 (the so-called non-return state). The vertical side portion 13-b of the L-shaped switching pawl 13 attached to the clutch lever 10 comes into contact with the end surface of the engaging portion 14-b of the check pawl 14. However, with respect to the clutch lever 10, the L-shaped switching pawl 13
Since the horizontal side 13-a of the L-shaped switching pawl 13 is pivotally attached to the locking screw 23, the vertical side 13-b of the L-shaped switching pawl 13 collides with the engaging portion 14-b of the non-return pawl 14. At the same time, the clutch lever 10 swings in a direction away from the vertical receiving part 20 and slides on the end surface of the engaging part 14-b, so that the pushing movement of the clutch lever 10 is not inhibited and the clutch lever 10 slides forward, the clutch hook pin 11 enters the engagement groove 12-b of the L-shaped engagement groove 12, and the clutch lever 1
The return of 0 is stopped.

In this state, when the handle 29 is rotated in the fishing line reeling direction, the non-return gear 25 rotates in the direction of arrow P.
When the claw portion 14-a of the non-return claw 14 comes off from above the teeth, the L-shaped switching claw 13 is rotated in the direction of arrow F by the elastic force of the switching claw spring 24, and the vertical side portion 13-b is rotated in the opposite direction. The engaging part 14-b of the stopper pawl 14 is pushed up, the claw part 14-a of the non-return pawl 14 is inserted into the valley of the non-return gear 25, and the vertical side part 13-b is inserted into the vertical receiving part of the clutch lever 10. 20, and thereafter perform the operation shown in FIG.
is returned to its original state and the clutch is turned ON.

FIG. 8 shows the non-return pawl 14 in the above-mentioned embodiment.
This shows a case where a non-return claw spring 28 is used instead of the guide plate 27, and the claw portion 14-a of the non-return claw 14 rides on the teeth of the non-return gear 25. When the handle rotates in the direction of arrow P, the pawl portion 14-a is removed from the top of the tooth portion and at the same time is pushed into the trough by the elastic force of the non-return pawl spring 28, and the engaging portion 14-a of the non-return pawl 14 is removed. b moves in the direction of arrow Q, the L-shaped switching pawl 13 is rotated by the elastic force of the switching pawl spring 24, and the vertical side 13-b hits the engaging portion 14-b of the non-return pawl 14. It swings without any movement and comes into contact with the vertical receiving part 20, resulting in the state shown in FIG.

Furthermore, rotate the handle 29 to lock the non-return gear 25.
When the clutch lever 10 rotates, the clutch lever 10 returns to its original state due to the action shown in FIG. 5, and the clutch becomes in the ON state.

In the figure, 30 is a friction plate constituting the drag mechanism, and 31 is a drag adjustment knob.

Since the clutch mechanism of the present invention is constructed as described above, the clutch mechanism of the present invention can be
Can quickly switch from OFF to clutch ON. In other words, since it utilizes the movement of the non-return pawl of the non-return mechanism, the clutch can be moved from the OFF state by rotating the handle by a rotation angle equal to 1/the number of teeth provided on the non-return gear. It can be returned to the ON state.

Moreover, the clutch switching pawl that is attached to return the clutch lever is pivotally attached to the clutch lever so that it can swing freely, so if the clutch switching pawl comes into contact with the engaging part of the non-return pawl. Also, the clutch lever can slide without being blocked and the clutch can be turned OFF, making it possible to provide a clutch mechanism without dead points.

Therefore, it is the most suitable clutch mechanism for a double-bearing reel, and can make fishing operations more comfortable.
