[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clutch mechanism for a double-bearing reel for fishing, and more particularly to a clutch mechanism for a double-bearing reel for fishing provided with a flipping mechanism.

[0002]

2. Description of the Related Art Conventionally, a technology relating to a clutch mechanism of a double-bearing reel for fishing is disclosed in Japanese Utility Model Laid-Open Publication No. 3-102854 (hereinafter referred to as "conventional example 1") and Japanese Patent Publication No. 2-4130.
No. 9 (hereinafter, referred to as "Conventional Example 2") and Japanese Utility Model 2
No. 46295 (hereinafter referred to as "Conventional Example 3") and the like.

[0003] First, the clutch mechanism disclosed in the prior art example 1 is described as follows: "In a dual-bearing reel configured so that the operation of the operating tool can be switched between a toggle mode and a momentary mode by a switching mechanism, Alternatively, a first method of applying a biasing force to a system linked to the operating tool
A spring and an operating tool in the momentary mode, or
A second spring for applying a biasing force to a system linked to the operating tool is separately provided, and the switching mechanism is configured to operate only one of the first spring and the second spring by the operating tool or the operating mechanism. And a selective type in which a biasing force is applied to a system associated with the tool. " That is, Conventional Example 1
According to the technique disclosed in Japanese Patent Application Laid-Open No. H11-157, the first spring or the second spring selectively acts on the operating tool or a system linked to the operating tool by the switching mechanism.

Further, the clutch mechanism of the dual-bearing fishing reel disclosed in the prior art example 2 discloses that a pinion that meshes with a drive gear of a handle shaft is slidably fitted on a spool shaft to which a spool is fixed. Then, the pinion is formed so as to be freely detachable from the spool shaft by a cam disk that rotates about the spool shaft, and the cam disk is biased so as to rotate left and right by a single dead point spring, Rotate the cam disk with the operating tool provided on the rear side of the spool to separate the pinion from the spool shaft, and rotate the cam disk in the opposite direction by rotating the handle shaft to engage the pinion with the spool shaft. In the fishing dual-bearing type reel, the position at which the dead point spring biases the cam disk in the left-right direction and the cam disk are pinioned Are summarized as switching freely formed was "things into a position for energizing only the engaging position.

Further, the clutch mechanism of the double-bearing reel for fishing disclosed in the prior art example 3 is described as follows: "The clutch mechanism is engaged with a drive gear rotated by a handle, and is fitted to the spool shaft so as to rotate and slide in the axial direction. The pinion with respect to the chamfered portion of the spool shaft is rotated by the operating tool supported on the reel body and moved in the axial direction by the clutch cam biased in the forward and reverse directions by the dead point spring. Is disengaged and clutch O
A clutch mechanism for a dual-bearing fishing reel, wherein the clutch cam is inverted by a ratchet rotating coaxially with the drive gear in the clutch OFF state, and the clutch body is provided so as to be switchable to the clutch ON state; In the right place, the flipping cam is pivotally supported so as to be operable to be switched, and one end is hooked to the operating tool so that the other end of the interposed dead point spring is movable so that the clutch of the dead point spring can be moved. The spring force on the cam is switchably provided by the flipping cam in two stages, both on the clutch ON side and the clutch OFF side and only on one side of the clutch ON side. "

That is, in the techniques disclosed in the prior art examples 2 and 3, the flipping mechanism is turned on and off by attaching one end of a single dead point spring to be freely displaceable.

[0007]

However, the prior art has the following problems. That is, in the conventional example 1, since the first spring is supported by the first support member and the second spring is supported by the second support member, the number of parts is large and the number of assembly steps is increased. There was a problem.

[0008] In Conventional Examples 2 and 3,
Since both the operating tool and the cam disk are returned from the clutch OFF state to the clutch ON state using only one dead point spring, there is a problem that the returning operation with the flipping mechanism ON is slow.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to reduce the number of parts, reduce the number of assembling steps, and quickly and reliably return the operating tool and the clutch cam when the flipping mechanism is ON. It is an object of the present invention to provide a clutch mechanism for a dual-bearing reel for fishing that can be used.

[0010]

In order to achieve the above object,
The clutch mechanism of the double bearing reel for fishing according to the present invention is:
A base end of the first intermediate member is integrally fixed to an operation tool supported between both side plates of the casing, and one end of a second intermediate member is rotatably supported at a distal end of the first intermediate member, The other end of the second intermediate member is engaged with the cam disk, the rotation of the cam disk releases the engagement between the pinion gear and the spool shaft, and the cam disk holds the cam disk in the clutch ON / OFF state. In the clutch mechanism of the dual-bearing reel for fishing in which the first spring is hooked, a second spring and a third spring are hooked on a switching member provided on the side plate for turning on and off the flipping mechanism. The third spring urges the switching member in the forward and reverse directions when the flipping mechanism is turned on and off, and the second spring urges the second member.
In the state where the flipping mechanism is OFF, the spring force does not act on the first intermediate member regardless of whether the clutch is ON or OFF. When the flipping mechanism is ON, the spring force is not applied to the first intermediate member. It is intended to work.

[0011] In the above configuration, the second spring and the third spring are turned on by the flipping mechanism and the clutch off.
In this state, the spring force of the third spring urging the switching member is set stronger than the spring force when the second spring is extended, and the first spring and the second spring However, when the flipping mechanism is ON and the clutch is OFF, the spring force when the second spring is extended is set to be stronger than the spring force of the first spring that urges the cam disk. Things.

[0012]

The flipping mechanism is such that the operating tool is turned with a finger, the clutch is turned off only while the operating tool is being pressed, and when the finger is released from the operating tool, the operating tool automatically returns to the original state. A mechanism that returns to the position and turns on the clutch. When the flipping mechanism is OFF,
Since the switching member is in a state of being rotated upward and held, even if the operating tool is rotated, the spring force of the second spring does not act on the first intermediate member. Therefore, even if the clutch is turned off by pressing the operating tool with a finger from the clutch ON state and then releasing the finger, the cam disk is held at the rotational position by the first spring, so that the clutch is turned off. The state is maintained.

On the other hand, in order to turn on the flipping mechanism, the switching member is rotated by a finger. Then, a spring force for rotating the first intermediate member is generated in the second spring. In this state, the clutch can be maintained in the OFF state only while the operating tool is being pressed with a finger. When the finger is released, the cam disk is rotated by the spring force of the second spring. Thus, the clutch quickly and reliably returns to the ON state.

Further, due to the spring force relationship between the second spring and the third spring, even if the second spring is extended to the state where the clutch is OFF by the flipping mechanism ON, the switching member does not rotate and the current position is maintained. Will do.

Further, due to the spring force relationship between the first spring and the second spring, the clutch is turned off by the flipping mechanism ON.
When the finger pressing the operating tool is released from the state described above, the first intermediate member is rotated by the spring force of the second spring, and the clutch is turned off.
It will be restored to the state of N.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a clutch mechanism for a double bearing reel for fishing according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a state in which the clutch is ON when the flipping mechanism is not operated and the clutch is ON. FIG. 2 shows a state in which the operating tool is turned and the clutch is turned off with the flipping mechanism turned off. FIG. 3 shows a state where the clutch is ON when the flipping mechanism is operated and turned ON. FIG. 4 shows the clutch OF with the flipping mechanism ON.
It shows the state of F.

Here, the flipping mechanism means that the operating tool 3 supported on the casing 2 of the dual-bearing fishing reel 1 is turned downward by a finger as shown in FIG. The clutch is in the OFF state only during the operation, and when the finger is released from the operation tool 3, the operation tool 3 automatically returns to the original position, and the clutch is in the ON state. . The clutch OFF state means a state in which the engagement between the spool shaft 4 and the pinion gear 16 is released, and the forward and reverse rotation of a spool (not shown) provided integrally with the spool shaft 4 is free. Say. Further, the clutch ON state refers to a state in which the spool shaft 4 and the pinion gear 16 are engaged.

An operation tool 3 is provided between both side plates 2a (one side plate is not shown) of the casing 2 of the dual bearing reel 1 for fishing.
The operating tool 3 is rotatably supported by an operating shaft 5. The first end of the operation shaft 5
The base end of the intermediate member 6 is fixed, and the first intermediate member 6 is interlocked with the rotation of the operating tool 3. One end of a second intermediate member 7 is engaged with the tip of the first intermediate member 6. A substantially central portion of the second intermediate member 7 is rotatably supported by the side plate 2a, and the rotation of the operation tool 3 is interlocked via the first intermediate member 6. The other end of the second intermediate member 7 is engaged with the cam disk 8. The cam disk 8 is a spool shaft 4 fitted with a spool (not shown) around which the fishing line is wound.
And is rotatably mounted on the casing 2 in a clockwise direction and a counterclockwise direction. That is, the rotation of the operation tool 3 is interlocked via the first intermediate member 6 and the second intermediate member 7.

A shifter 9 is provided coaxially with the spool shaft 4. In FIG. 1, when the cam disk 8 rotates counterclockwise, the protrusion provided on the cam disk 8 raises the shifter 9 upward with respect to the paper surface and locks the shifter 9. The engagement between the pinion gear 16 and the spool shaft 4 is released. One end of a first spring 10 is hooked to the cam disk 8, and the first
The other end of the spring 10 is hooked on the side plate 2 a of the casing 2. The first spring 10 is formed by a spring whose bent portion has a coil shape and whose both ends have a C-shape. The first spring 10 acts so as to urge the cam disk 8 in the clockwise direction when the clutch is ON, and to urge the cam disk 8 in the counterclockwise direction when the clutch is OFF.

Further, a switching member 11 is rotatably supported between the side plate 2a of the casing 2 and a lid (not shown). The rotation of the switching member 11 is restricted by a fan-shaped elongated hole 2b formed in the side plate 2a, and the switching member 11 is rotated only in the fan-shaped elongated hole. The switching member 11 is provided with two spring retaining portions 11a and 11b. In the figure, the upper spring retaining portion 11a has a second
The spring 12 is hooked. The second spring 12 is formed by a coil spring that exerts a spring force in the compression direction. The second spring 12 has one hooking hook portion 12a formed to be long in the axial direction, and the hooking hook portion 12a is an engaging portion between the first intermediate member 6 and the second intermediate member 7. Is hung on the pin 13 located at the position. On the other hand, in the figure, one of the lower spring retaining portions 11b is attached to the side plate 2a.
The third spring 14 is hooked. The third spring 14 is formed by a spring whose bent portion has a coil shape and whose both ends have a C-shape. The third spring 14 is in a state where the flipping mechanism is ON (FIG. 3).
And the state shown in FIG. 4), the switching member 11 is always urged in the clockwise direction. When the flipping mechanism is OFF (the state shown in FIGS. 1 and 2), the switching member 11 is always urged in the counterclockwise direction. It is attached so as to rush.

As described above, the second spring 12 has one hook hook portion 12a formed to be long in the axial direction. Therefore, in the state where the flipping mechanism is OFF (the state of FIGS. 1 and 2), in either the state of the clutch ON or the state of the clutch OFF, the pin 13 is not extended by the operation of the pin 13, and the spring force is reduced by the first intermediate member 6 and It does not act on the second intermediate member 7. When the flipping mechanism is ON (the state shown in FIGS. 3 and 4), the switching member 11 is rotated clockwise, so that the spring retaining portion 11a above the switching member 11 moves downward. Will be located. Therefore, the second spring 12 is extended by the pin 13 in either the clutch ON state or the clutch OFF state, and rotates the first intermediate member 6 in the clockwise direction. The spring force for rotating the counterclockwise 7 is applied.

The spring force relationship between the second spring 12 and the third spring 14 is smaller than the spring force when the second spring 12 is extended when the clutch is OFF with the flipping mechanism ON (FIG. 4). The third spring 14 is set such that the spring force for urging the switching member 11 clockwise becomes stronger. Therefore, even if the second spring 12 is extended in the clutch OFF state (the state shown in FIG. 4) by the flipping mechanism ON, the switching member 11 does not rotate, and the current position can be maintained.

The spring force relationship between the first spring 10 and the second spring 12 is such that the spring force when the second spring 12 is extended in the state where the clutch is OFF and the flipping mechanism is ON (the state shown in FIG. 4). The cam disc 8 is set to be stronger than the spring force of the first spring 10 which biases the cam disc 8 in the counterclockwise direction. Accordingly, when the finger pressing the operating tool 3 is released from the clutch OFF state (the state of FIG. 4) by the flipping mechanism ON, the first intermediate member 6 is rotated clockwise by the spring force of the second spring 12. Pivoted to
The clutch is returned to the ON state (the state shown in FIG. 3).

In the figure, reference numeral 15 denotes a ratchet rotated by a handle (not shown), and its teeth are adapted to engage with the kick claws 8a of the cam disk 8. Next, the operation of the above embodiment will be described.

As described above, when the flipping mechanism is OFF (the state shown in FIGS. 1 and 2), the switching member 11 is turned off.
Is rotated upward. Accordingly, since the spring retaining portion 11a of the switching member 11 is located at an upper position in the drawing,
Operate the operation tool 3 with the flipping mechanism OFF and set the clutch to O
Even if the second spring 12 rotates to the state of the FF (the state of FIG. 2),
Does not act on the pin 13.

Therefore, after the operating tool 3 is pressed by a finger to change the clutch to the OFF state (the state shown in FIG. 2) from the state where the clutch is turned ON by the flipping mechanism OFF (the state shown in FIG. 1),
Even when the finger is released, the clutch remains in the OFF state. To return the clutch to the ON state (the state shown in FIG. 1), the handle is rotated to operate the kick claw 8a of the cam disk 8 with the teeth of the ratchet 15, and the cam disk 8 is turned on. (The state shown in FIG. 1).

Next, the state of the flipping mechanism ON (FIG. 3)
4), a knob (not shown) supported by a lid (not shown) and provided integrally with the switching member 11 is rotated clockwise by a finger. Then, the spring retaining portion 11a of the switching member 11 is located below in the figure. As a result, a spring force for always rotating the first intermediate member 6 in the clockwise direction is generated in the second spring 12.

In this state, the clutch can be maintained in the OFF state (the state shown in FIG. 4) by the flipping mechanism ON only while the operating tool 3 is being pressed with a finger. Then, the spring force of the second spring 12 causes the flipping mechanism ON to return to the clutch ON state (the state in FIG. 3).

In this embodiment, a pin 13 is provided on the first intermediate member 6 for drivingly connecting the operating tool 3 and the cam disk 8 in the clutch mechanism, and the second spring 12 engaged with the pin 13 is provided. Is hooked on the switching member 11 and the switching member 11
Since the flipping mechanism is configured only by hooking the third spring 13, the number of parts is reduced as compared with the first conventional example, and the number of assembling steps can be greatly reduced.
