Abstract

PROBLEM TO BE SOLVED: To provide a radio controlling transmitter capable of steplessly adjusting a neutral position without changing a manipulated variable from the neutral position on the forward movement side and a manipulated variable from the neutral position to a full open position on the reverse side in a trigger. SOLUTION: For a rigger unit 10, a mounting position in a main body can be slid forward and backward by tightening or loosening a position adjusting screw 22. Since the trigger unit 10 can be adjusted not by steps but steplessly to a desired position within a slidable range relative to the main body, the position of a trigger can be adjusted to adapt the size of an operator's hand by almost any operator, so the trigger 2 can be adjusted to a suitable position by any operator from a child to an adult. As a manipulated variable of the trigger 2 is not changed, deterioration of operability can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a radio control transmitter which is a controller for transmitting a control signal to a controlled machine (in particular, a radio control car).

[0002]

2. Description of the Related Art Radio control cars have been enjoyed in a wide range of generations from children to adults. A general controller (RC transmitter) for operating a radio controlled car is called a wheeler & grip type. The operation of the radio controlled car in the traveling direction (steering wheel operation) is performed by the steering wheel, and the speed control (forward / reverse) The switching is performed by a throttle trigger (hereinafter, simply referred to as a trigger). The operator controls the traveling direction of the radio controlled car by rotating the steering wheel arranged on the right side of the controller with the right hand, and presses the trigger arranged in front of the grip of the controller with the left hand holding the grip. Control the speed of the radio controlled car by turning it back and forth with your index finger.

By the way, when the trigger is operated suddenly (for example, when it is operated from the neutral position to the fully open position on the forward side at a stretch), the tire of the radio controlled car loses its grip and loses its grip and becomes uncontrollable. In order to prevent sudden operation of the trigger, it is necessary to set the operation range of the trigger in a range where the index finger of the left hand of the operator moves smoothly without difficulty. That is, it is desirable to arrange the trigger at a position where the operator can smoothly operate the trigger.

As described above, since radio controlled cars are enjoyed by many people in a wide range of generations, the size of the hands of the operators who operate the controller varies widely, so that a trigger desirable for each operator is desired. The position was also different. Therefore, it is desirable that each operator can adjust the position of the trigger in the controller according to the size of his / her hand (the range in which the index finger of the left hand moves smoothly without difficulty).

[0005]

However, the conventional general controller sets the neutral position of the trigger to two.
The switching was performed in stages. Specifically, assuming that the total operation amount of the trigger is 10, the ratio of the operation range from the neutral position to the fully open position on the forward side and the operation range from the neutral position to the fully open position on the reverse side is either 7: 3 or 5: 5. It was configured to be adjustable. Thus, in the conventional general controller, the neutral position of the trigger is 2
Many operators could not adjust the position of the trigger according to the size of their hands, because they could only be switched in stages.

When the neutral position of the trigger is shifted, the amount of operation from the neutral position to the fully open position on the forward side and the amount of operation from the neutral position to the fully open position on the reverse side change. In particular, when the ratio of the operation range of the trigger is 5: 5, the operation amount on the forward side decreases,
There is a high risk of the operator accidentally performing a rapid acceleration operation and damaging the radio controlled car (there is a problem that the operability is reduced). It is generally said that the operability is better when the ratio of the trigger operation range is 7: 3.

An object of the present invention is to change the operation amount of the trigger from the neutral position to the fully open position on the forward side and the operation amount from the neutral position to the fully open position on the reverse side without changing the neutral position steplessly. An object of the present invention is to provide a radio control transmitter capable of adjustment.

[0008]

A radio control transmitter according to the present invention has the following arrangement to solve the above-mentioned problems.

(1) A radio control transmitter for transmitting a control signal corresponding to an operation amount of an operation unit to a controlled machine, comprising a trigger unit having a throttle trigger functioning as the operation unit, wherein the throttle trigger comprises: The trigger unit is rotatably mounted on a shaft provided on the trigger unit, and the trigger unit is configured such that a mounting position on a main body is slidable.

(2) An adjusting mechanism is provided for adjusting the mounting position by sliding the trigger unit with respect to the main body.

(3) An adjustment regulating mechanism for regulating the slide of the mounting position by the adjusting mechanism is provided.

In the above configuration (1), since the trigger unit to which the trigger is attached is slidably attached to the main body, sliding the trigger unit also changes the neutral position of the trigger. At this time, since the trigger slides along with the trigger unit, the operation amount of the trigger (the operation amount on the forward side and the reverse side) does not change. Also, the trigger unit can be adjusted steplessly to any position within the slidable range with respect to the main body, not stepwise, so that the neutral position of the trigger can also be steplessly adjusted.

Therefore, most operators can adjust the position of the trigger according to the size of their hands. Further, even if the position of the trigger is adjusted, the operation amount of the trigger (the operation amount on the forward side or the reverse side) does not change, so that there is no problem that the operability is reduced.

In the configuration (2), since the adjusting mechanism for adjusting the mounting position by sliding the trigger unit is provided, the neutral position can be easily adjusted.

In the configuration (3), since the slide of the mounting position by the adjusting mechanism is regulated, if the adjusting regulating mechanism is operated, the trigger unit is in use during use. , And the neutral position of the trigger does not change.

The radio control transmitter 1 transmits the resistance value of the potentiometer 12 as a speed control signal to the radio control car.

FIG. 3A is a schematic view showing a mounting structure of a throttle trigger unit in a radio control transmitter according to an embodiment of the present invention, and FIG. 3B is a trigger unit of the radio control transmitter according to this embodiment. It is sectional drawing which shows the state to which was attached. As shown in FIG. 3, a guide 21 in which the outer peripheral portion of the trigger unit 10 is in contact with the mounting position of the trigger unit 10 is formed in the main body case 20 of the radio control transmitter 1. Further, an insertion portion 23 for inserting the screw head of the position adjusting screw 22 is formed at a position facing the position adjusting nut 15 provided on the trigger unit 10 disposed at the mounting position. Screw 22 is screwed into the position adjusting nut 15. The position adjusting screw 22 and the position adjusting nut 1
Reference numeral 5 corresponds to an adjusting mechanism section according to the present invention.

Further, a threaded fixing portion 24 is provided at a position facing the hole 16 of the trigger unit 10. 25 is a fixing screw for fixing the trigger unit 10 by screwing the fixing unit 24 through the hole 16. The hole 16, the fixing portion 24, and the fixing screw 25 correspond to the adjustment regulating mechanism in the present invention.

As shown in FIG. 4, the screw head of the position adjusting screw 22 inserted into the insertion portion 23 is as follows.
An opening 31 is formed in the main body case 20 so that the driver can be directly operated from the outside of the radio control transmitter 1 main body. Note that a portion indicated by hatching in the drawing is the trigger unit 10 (the trigger 2 is not partially hatched). Although not shown, the main body case 20 of the radio control transmitter 1 also has an opening in the main body cover 20 so that the screw head of the fixing screw 25 can be directly operated from outside the main body. Therefore,
In the radio control transmitter 1 of this embodiment, the screw 22 for position adjustment and the screw 25 for fixing can be operated by the driver without disassembling the main body (without opening the main body case).

Next, adjustment of the position of the trigger unit in the radio control transmitter according to this embodiment will be described with reference to FIG. Since the hole 16 is a long hole as described above, when the fixing screw 25 for fixing the trigger unit 10 to the main body is loosened, the trigger unit 10 slides in the front-back direction of the main body (the left-right direction shown in FIG. 5). Can be done. It is not necessary to open the main body case 20 when loosening or tightening the fixing screw 25 as described above.

Then, with the fixing screw 25 loosened,
When the position adjusting screw 22 is tightened to the position adjusting nut 15, for example, the position adjusting screw 22 is tightened from the state shown in FIG. 5A (the fixing screw 25 is loosened). The screwing position between the adjusting screw 22 and the position adjusting nut 15 moves to the screw head side (left side in the figure). The position adjustment nut 15 is the trigger unit 10
, The position relative to the trigger unit 10 does not change. Further, since the screw head for the position adjustment screw 22 is inserted into the insertion portion 23 formed in the main body case, the position relative to the main body case does not change. Accordingly, as the position adjusting screw 22 is tightened, the trigger unit 10 slides forward with respect to the main body (the state shown in FIG. 5A changes to the state shown in FIG. 5B). That is, by tightening the position adjustment screw 22, the trigger unit 10 can be moved forward with respect to the main body. In addition, X shown in the figure is the slide amount of the trigger unit 10.

When the position adjusting screw 22 is rotated in the loosening direction, the screwing position between the position adjusting screw 22 and the position adjusting nut 15 moves toward the distal end, so that the position adjusting screw 22 is loosened. , The trigger unit slides rearward (to the right in the figure) with respect to the main body 1 (changes from the state shown in FIG. 5A to the state shown in FIG. 5C). That is, by loosening the position adjusting screw 22, the trigger unit can be moved backward with respect to the main body. In addition, Y shown in the figure is a slide amount of the trigger unit 10.

The trigger 2 slides with respect to the main body together with the trigger unit 10, and the neutral position changes. That is, the position adjusting screw 22 is tightened,
By loosening it, the neutral position of the trigger 2 can be adjusted. In addition, the trigger unit 10 can be adjusted to an arbitrary position (however, within a slidable range) depending on the tightening state of the position adjusting screw 22, so that the neutral position of the trigger 2 can be adjusted to an arbitrary position (stepless). Can be adjusted with.). Therefore, each operator can adjust the position of the trigger 2 according to the size of his / her hand.

Further, since the neutral position of the trigger 2 is adjusted by sliding the trigger unit 10 with respect to the main body, even if the neutral position of the trigger 2 is changed, the trigger 2 moves forward from the neutral position of the trigger 2. Does not change from the neutral position to the fully open position on the reverse side, so that the operability is not reduced. Furthermore, since the position adjusting screw 22 and the fixing screw 25 can be directly operated from the outside of the main body, the operation of adjusting the neutral position of the trigger 2 can be easily performed (with no work such as removing the main body cover). ). Further, by fixing the trigger unit 10 to the main body with the fixing screw 25, there is no problem that the trigger unit 10 slides during use (the neutral position of the trigger 2 does not change during use). ).

Next, another embodiment of the present invention will be described. In the above-described embodiment, the position of the trigger unit in the main body is adjusted using the position adjusting screw 25. In this embodiment, as shown in FIG. 6A, elongated holes 31 are formed on both sides of the trigger unit. The fixing part 32 was formed and screwed into the main body case 20.
