Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand lever device for operating a driven member such as a throttle valve of an internal combustion engine via a cable, and more particularly to a handle for a working machine such as a hedge trimmer or a bush cutter. The present invention relates to a hand lever device which is disposed near a grip portion and is suitable for opening and closing the throttle valve via a throttle cable.

[0002]

2. Description of the Related Art For example, in a working machine such as a hedge trimmer or a bush cutter driven by a working unit such as a cutting blade by an internal combustion engine, the output of the internal combustion engine is adjusted at hand. A hand lever device for adjusting the opening of a throttle valve of the internal combustion engine is disposed near a grip portion such as a U-shaped handle or a bar handle.

[0003] This hand lever device usually has a throttle trigger (throttle lever) which is operated by a finger of an operator. When the throttle lever is oscillated, the throttle valve is opened via a throttle cable. The degree is adjusted. Normally, the throttle valve is normally biased in the direction of the minimum opening (idle rotation opening), and is held at the idle rotation opening when the throttle lever is not operated, and the throttle cable is pulled for a predetermined length or more. When this occurs, play is eliminated and the opening from the idle rotation opening to the high-speed rotation side is started.

In such a hand lever device for adjusting the opening degree of a throttle valve, when the throttle lever is released from a rotating operation state, the lever is automatically moved together with the throttle valve to its original position (idle rotation). Opening), and a fixed type, in which the throttle lever can always be held at a desired rotational operation position in an immovable state even when a finger is released, and a type in which the automatic idle rotation opening degree is returned to the original type. The thing is known (Jiko 57-19944)
Reference).

In the automatic return type, when the finger is released from the throttle lever, the engine automatically returns to the idling state, and the engine rotational driving force is transmitted to a working unit including a cutting blade or the like via a centrifugal clutch. Work machine,
Since the centrifugal clutch is disengaged and power transmission to the working unit is cut off, in the event of an unexpected situation, the working unit can be stopped by immediately returning the throttle valve to the idle rotation opening. On the other hand, while the advantage that safety is enhanced is obtained, the throttle lever must be always held by a finger to maintain a desired rotational operation position, so that it is difficult to use the intermediate opening degree, the finger becomes tired, and the operation amount ( Rotation speed) is not constant.

In general, in consideration of usability, a rotary operation lever operated by a finger, such as a throttle lever, takes only two positions of a release position and a set position (grip position) without taking an intermediate opening degree. It is desirable to make the same rotary operation position (set position) when the throttle valve is set to the intermediate opening degree (partial opening degree) and when the throttle valve is fully opened (WOT). Considered excellent.

On the other hand, the fixed type can solve the problem of the automatic idle rotation opening degree return type, and always keeps the throttle lever in a desired rotational operation position in a stationary state even when the hand is released. Although it has the advantage of being able to work freely and fingers freely, in the event of an unexpected event, a separate operation to release the position holding function of the throttle lever is required, and Cannot be stopped, there is a problem that the safety is inferior to that of the automatic idle rotation opening return type.

In any of the above-mentioned types, after the throttle lever is once released and the operation is interrupted, the throttle valve is returned to the previous opening in order to resume the operation. In many cases), the rotational operation position of the throttle lever must be readjusted, and the operation is troublesome, and there is still room for improvement in operability.

In order to solve or attain the conventional problems and problems relating to the above-described hand lever device, the applicant of the present invention has previously disclosed, for example, Japanese Patent Application Laid-Open No. Hei 8-303262, It has a main lever and a sub-lever that are operated to move, and the cable connected to the driven member is pulled by the sub-lever via a folding member such as a moving pulley, and the folding member is moved by the main lever. A hand lever device adapted to be operated is proposed.

According to the hand lever device, the opening of the throttle valve or the like as the driven member can be adjusted via the cable and can be easily held at the desired opening.
In addition, the valve can be immediately returned to the minimum opening (idle rotation opening) to ensure high safety, reduce finger fatigue, and furthermore, the opening before returning the throttle valve to the idle rotation opening. In such a case, it is possible to eliminate the need for readjustment even when resetting is required.

[0011]

However, in the proposed hand lever device, when the main lever is at the release position where the main lever is not rotated (during idling), slack (play) occurs in the throttle cable. Therefore, when the sub-lever is rotated, the throttle cable moves, though slightly, causing a problem that the opening degree of the throttle valve, which is the driven member, changes and the idle speed fluctuates. Such a change in the idling speed does not cause a problem in operation, but may reduce the reliability and commercial value of the hand lever device.
It is desired to improve. In addition, in the proposed hand lever device, in addition to the above problem, since the cable is slackened, the cable is easily detached from the connecting portion or the folded member, two cables are required, the assemblability is poor, and the like. There were also problems.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. It is an object of the present invention to enable the opening degree of a throttle valve or the like as a driven member to be adjusted via a cable. The desired opening can be easily maintained, and the minimum opening (idle rotation opening) is immediately obtained.
To ensure high security,
Fingers can be made less tiring, and even if you want to reset the throttle valve to the opening before returning to the idle rotation opening, you can eliminate the need for readjustment. An object of the present invention is to provide a hand lever device capable of preventing an undesired movement from occurring and improving an assembling property.

[0013]

In order to achieve the above object, a hand lever device according to the present invention basically comprises a main lever which is operated to rotate, and a main lever which rotates about a first rotation axis. A sub-lever that is operated and held immovably at an arbitrary rotational operation position, and pivots about a second rotational axis disposed on an integral pivot that is integrally pivoted with the sub-lever. A pulling lever to be controlled, a cable for controlling the driven member is connected to the pulling lever, and the pulling lever is rotated about the second rotation axis by the main lever. Being adapted to pull the cable,
When the main lever is at the release position where the sub-lever is not pivoted, the position of the coupling point between the pull lever and the cable is kept constant regardless of the pivotal operation position of the sub-lever. It is characterized by having.

In a preferred aspect of the present invention, the position of the connection point when the main lever is at the release position is set on the first rotation axis. In another preferred embodiment, the main lever, the sub-lever, and a case member having a two-part configuration including a left cover case and a right cover case are biased to one side of the left cover case and the right cover case. The pull lever is disposed, and a lock mechanism that locks the main lever at the release position is disposed on the other side.

A typical, but non-limiting application of the hand lever device according to the present invention is for use in adjusting the opening of a throttle valve of an internal combustion engine. In a preferred aspect of the hand lever device according to the present invention having the above-described configuration, even when the main lever is at the release position (during idling), the cable for controlling the driven member (throttle valve) is loosened. (play)
Cable length etc. is set in advance so that no
When the main lever is turned to the set position, the cable is pulled, and accordingly, the throttle valve is turned from the minimum opening (idling opening) to the opening direction, so that the sub-lever is turned. The opening is adjusted according to.

Here, in the hand lever device of the present invention,
When the main lever is at the release position (idling), the position of the connection point between the pull lever and the cable is set on a first rotation axis which is a rotation fulcrum of the sub lever, and the rotation of the sub lever is set. Regardless of where the moving operation position is on the high-speed side or the low-speed side, the position of the connection point between the pulling lever and the cable is set to be constant. Since the cable does not move, and therefore, the throttle valve also maintains the idle rotation opening degree, the idle speed does not fluctuate and becomes stable, and the cable does not become slack because the cable does not slack. It becomes difficult to come off from the connecting portion and the like, and as a result, the reliability of operation is increased and the commercial value is improved.

In the hand lever device 10A of the present embodiment having the above-described configuration, the main lever 30
6 and 8, the cable length and the like are set in advance so that the slack (play) does not occur in the throttle cable 16 for controlling the throttle valve CV even when the throttle cable 16 is in the release position F (idling). The position of the connection point K between the pull lever 40 and the cable 16 is set on the first rotation axis Oa, which is the rotation fulcrum of the sub-lever 50, and the rotation operation position of the sub-lever 50 is set to the low-speed side L.
Regardless of the position on the high-speed side H (FIG. 8), the position of the connection point K is fixed (immobile), so that when the main lever 30 is at the release position F when idling, Even if the sub-lever 50 is rotated, the cable 16 does not move, and the throttle valve CV also maintains the idle rotation opening degree, so that the idle speed does not fluctuate and becomes stable. Further, since the cable 16 is not slackened, it is difficult for the cable 16 to come off from the connecting portion or the like. As a result, the reliability of operation is increased and the commercial value is also improved.

When the lock lever 80 and the main lever 30 are pivotally operated to the set position S close to the rear grip portion 11 by grasping the pin 1, the pin boss portion 44 of the pull lever 40 is rotated clockwise by the pushing lever 37. And the position of the connection point K between the pulling lever 40 and the cable 16 is shifted by the first rotation axis Oa.
Moving forward from above, the cable 16 is pulled, and the throttle valve CV is set to the minimum opening (idling opening).
The sub-lever 50 is rotated in the opening direction, and is adjusted to an opening degree corresponding to the rotation operation position of the sub-lever 50.

Further, when it is desired to drastically reduce the rotational speed of the engine 2 immediately after an unexpected situation occurs, for example, when the opening of the throttle valve CV is adjusted, the main lever 30 is released. Thus, since the throttle cable 16 is constantly biased in the closing direction of the throttle valve CV, the pulling lever 40 is rotated in the opposite direction (counterclockwise) to the above, and The connecting point K with the cable 16 is returned to the position on the first rotation axis Oa, the cable 16 is in the non-operation state, the throttle valve CV returns to the idle rotation opening degree, and the engine 2 It becomes an idling state.

Here, in the case of the working machine 1 in which the engine rotation driving force is transmitted to the working unit 3 composed of a cutting blade or the like via a centrifugal clutch, the centrifugal clutch is turned off and the working unit 3 is turned off. Since the power transmission to the cutting blade is cut off, the operation of the cutting blade and the like is immediately stopped. Once the main lever 30 is released, the main lever 30 is released again.
Is rotated to the set position S close to the rear grip portion 11, the sub-lever 50 remains held at the previous operation position. Therefore, the throttle valve CV is opened before the main lever 30 is released. The sub-lever 50 need not be readjusted again.

Therefore, in the hand lever device 10 of the present embodiment, the throttle valve C as the driven member
The opening of the V can be adjusted via the cable 16 and can be easily maintained at a desired opening, and can be immediately returned to the minimum opening (idle rotation opening) to ensure high safety. , Makes your fingers less tiring, and
When it is desired to set the throttle valve CV to the opening before returning to the idle rotation opening, readjustment can be unnecessary.

It is connected to. Further, a push lever 37 is provided integrally with the main lever 30,
The push lever 37 pushes the pin boss 44 of the pull lever 40 counterclockwise from the rear side to the front side, contrary to the first embodiment.

Also in the hand lever device 10B having such a configuration, when the main lever 30 is at the release position as shown in FIGS. 10 and 12 (during idling), the throttle cable 16 for controlling the throttle valve CV is loosened. The cable length and the like are set in advance so that (play) does not occur.
Is set on the first rotation axis Oa, which is the rotation fulcrum of the sub-lever 50, and the rotation operation position of the sub-lever 50 is changed from the high speed side H (FIG. 10) to the low speed side L.
(FIG. 12), the position of the connection point K is set to be constant, so that the sub lever 50 is idling when the main lever 30 is at the release position F.
Even if the cable is rotated, the cable 16 does not move, and the throttle valve CV also keeps the idle rotation opening degree, so that the idle speed does not fluctuate and becomes stable. Since the cable 16 is not loosened, the cable 16 is hardly detached from the pulley 70, the connecting portion, or the like. As a result, the operation reliability is increased and the commercial value is also improved.

FIGS. 13 to 15 show a third embodiment of the hand lever device according to the present invention. In the hand lever device 10C of the present embodiment, portions having the same functions as those of the respective portions of the above-described hand lever devices 10A and 10B of the first and second embodiments are denoted by the same reference numerals, and redundant description thereof will be omitted. In the following, differences will be mainly described.
