BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick device used for a transmitter of a radio control device and for remotely controlling a controlled object according to an operation amount.

[0002]

2. Description of the Related Art Conventionally, a radio control device has been used when remotely controlling a modeled vehicle such as a car, a boat or an airplane by radio waves. The radio control device is composed of a transmitter operated by the operator, a receiver mounted on the driven body, a servo device, and the like.

FIG. 4 is a diagram showing a transmitter of a radio control device. In the figure, 101 is a transmitter, and a pair of left and right stick devices 102 and 103 are arranged on the front surface of the transmitter.
When the operator operates the stick levers 102a and 103a of the stick devices 102 and 103 in the up and down and / or left and right directions with the left and right fingers, respectively, control radio waves are output from the transmitter in accordance with the operation amount. Then, the control radio wave is received by the receiver, and the servo device or the like is controlled based on the received signal to operate the operation unit of the controlled object.

When the model is a boat, two engines or motors may be used as power sources for traveling. Similarly, in the case of a model airplane, two engines or motors may be used in a twin-engine aircraft or the like.

Conventionally, in such a case, in such a pair of stick devices 102 and 103, the stick lever 103a is operated up and down to operate one engine or motor, and the stick lever 102a is operated up and down to operate the other engine or motor. The motors were controlled independently of each other. Further, the stick lever 102a is operated left and right to operate the rudder.

Then, when the boat is moved forward, backward or stopped, the stick lever 102 is used.
a and 103a are simultaneously operated in the vertical direction. When changing the direction of the boat, the steering amounts of the two engines or motors are changed by changing the operation amounts of the stick levers 102a and 103a, and the steering levers are operated left and right. Was being operated. In addition, the control of two engines or motors and the operation of the rudder were performed simultaneously.

Further, when controlling two engines or motors, it is also possible to control two engines or motors by operating, for example, one stick lever 103a using mechanical or electrical interlocking means. It was being appreciated.

For example, in the case of an engine, when the stick lever 103a is operated, the two servo devices are made to electrically move together, and the throttle lever of each engine is operated by each servo device, or one servo device is operated. With a servo device, mechanically interlock using a link mechanism,
It was common to operate the throttle lever of each engine. In this case, only the rudder was used to change the direction of the boat or the like.

[0009]

[Problems to be solved by the invention] By the way, stick
Use both hands to operate levers 102a and 103a simultaneously.
Have to operate with. And stick lever
102a is for operating an operation unit other than the engine and the motor
Used to do. For that reason, stick with both hands
-While operating 102a and 103a separately,
Control either the engine or the motor while
Do not operate other operating parts with the quick lever 102a.
However , there is a problem that the operability is poor.

When two sticks 103 are mechanically or electrically interlocked to control two engines and motors, one stick lever 103a is used.
Since it can be operated with, the operability is good, but there are variations in the characteristics of individual engines and motors, and there is a problem that the adjustment work is extremely complicated to control them perfectly in tandem.

[0011]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and when simultaneously controlling two engines or motors mounted on a controlled object,
It is an object of the present invention to provide a stick device of a radio control device which can be finely adjusted and has good operability.

The configuration of the present invention is used in a radio control device for remotely controlling a controlled object, and includes a variable resistor arranged in a fixed portion and a stick lever connected to a movable shaft of the variable resistor. In a stick device that controls the output from the variable resistor according to the turning position of the stick lever, the variable resistor is held with respect to the fixed portion so that the turning axes of the variable resistor face each other, and A pair of stick levers are arranged on the rotary shaft in a direction orthogonal to the rotary shaft, respectively.
It is characterized in that the rotating shaft of the variable resistor can be operated independently by operating each individually . In the stick device, the stick lever is selectively connected by a connecting member.

[0013]

With the above-mentioned structure, the operator can control two engines or motors with one hand when remotely controlling the controlled object. Moreover, the two engines or motors can be individually controlled.
