Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a stay device used in a radio control device (hereinafter abbreviated as radio control device), and particularly relates to an automatic return device that returns the stay to a neutral point. The present invention relates to a stick device for a radio-controlled device, in which the automatic return function of the stick can be freely released as needed, and the stick can be fixed in any position.

[Prior art]

Generally, in radio-controlled equipment that remotely controls controlled objects such as model cars, ports, airplanes, and helicopters using radio waves, a states lever is used to rotate the rotation axis of the variable resistor relative to the variable resistor body. The robot controls the radio waves emitted from the transmitter to control the amount of drive of various servo mechanisms mounted on the steered object, thereby controlling the running speed and direction of the steered object.

In this case, there are various types of drive mechanisms for the states lever, depending on the type of the steered object and the operating part, but the drive mechanism of the variable resistor that remotely controls the rudder of the steered object, etc. Normally, when the operator releases the states lever,
A so-called states lever automatic return mechanism, in which the states lever automatically returns to a predetermined neutral position, is widely used.

There are two types of states levers that are equipped with the above-mentioned automatic return mechanism to the neutral point, and others that are not equipped with the automatic return mechanism and can hold the states lever in any position. There is a type that can hold the position more reliably.

For example, in a transmitter for a model airplane, the automatic return mechanism is not provided in the operating direction of the states lever for controlling the output of the model engine, so that even if the pilot releases the states lever, the control amount remains the same. Furthermore, a fixing mechanism is provided to more reliably fix the position of the stay lever.

Furthermore, an automatic states lever return mechanism is provided in the operating direction of the states levers for operating the elevator, rudder, and ailerons that control the flight direction of the model airplane.

In addition, in general, in radio-controlled transmitters, the 6th
As shown in the radio-controlled transmitter 1 of Utility Model Application No. 57-77796 shown in the figure, two state levers 2 and 3 are provided. Each States Clever 2,3
is configured so that it can be operated up, down, left and right, and two types of remote control can be performed with a single states lever. Therefore, in this case, up to four types (4 channels) of remote control are possible.

Hereinafter, a concrete explanation will be given using a stay in which a stay lever is provided with an automatic return mechanism and a fixing mechanism.

4 and 5 show a conventional stay device disclosed in Japanese Utility Model Application No. 57-169393, in which FIG. 4 is a plan view thereof, and FIG. 5 is a rear view thereof. be.

The stay device 4 includes an outer case 5, two zero point fine adjustment devices 6, 6 attached to the case 5, two movable frames 7, 8 as movable members, and a state attached to the movable frame 8. It has clever 9. A rectangular window portion 10 is bored approximately in the center of the case 5. The movable frame 7 is a semi-cylindrical member, with one rotation axis being the rotation axis 11a of the variable resistor 11 attached to the case 5, and a rotation axis 12 provided on the case 5. is the other rotating shaft, and is rotatably provided with respect to the case 5. This movable frame 7 has two operation pins 1.
3 and 13 are arranged, rotates together with the movable frame 7, and is attached to the case 5.
It is configured to press.

The return arm 14 has one end 14a connected to the case 5.
A spring 15 as an elastic member is attached to the other end 14b,
It acts to constantly press the return arm 14 against the operation pins 13, 13. Therefore, the states lever 9 allows the movable frame 8 to be
When the movable frame 7 is rotated through the lever, one of the operation pins 13 will be pressed by the return arm 14, and when the states lever 9 is released, the movable frame 7 will automatically return to the predetermined original position. Configured to return.

Next, a small window 7a is bored approximately in the center of the movable frame 7, and the movable frame 8 is loosely fitted into the small window 7a so as to be freely rotatable. The rotating shaft of the movable frame 8 is composed of a rotating shaft 16a of the variable resistor 16 fixed to the movable frame 8, and a rotating shaft 17. 17 is rotatably attached to the movable frame 7. Further, the automatic return mechanism of the movable frame 8 with respect to the movable frame 7 is formed with the same structure as the automatic return mechanism of the movable frame 7. And on this movable frame 8,
The base of the states lever 9 is directly planted, and when the states lever 9 is driven vertically, horizontally, or diagonally, the movable frames 7 and 8 rotate.
The variable resistors 11, 16 are configured to be operated to control the output of the transmitter.

On the other hand, the movable frame 7 is formed with a fan-shaped notch portion 18 centered on the rotating shaft 12 and having a gear-shaped groove formed on the outer periphery. This notch portion 18 is a portion that functions as a part of the fixing mechanism of the movable frame 7 when the movable frame 7 is not provided with the above-mentioned automatic return mechanism. That is, when the return arm 14 and spring 15 attached to the movable frame 7 are removed, a notch spring 19 is provided as shown by the broken line,
The notch spring 19 is pressed against the groove of the notch portion 18 to provide resistance to the rotational movement of the movable frame 7. When the movable frame 7 is equipped with an automatic return mechanism, the notch spring 19 is used in a state where it is oriented in a direction where it is not pressed by the groove of the notch portion 18. As described above, when using the fixing mechanism, the function of the fixing mechanism cannot be fully exerted unless the return arm 14 and spring 15 as an automatic return mechanism are removed.

[Problem that the invention attempts to solve]

When operating the stay lever, depending on whether or not an automatic return mechanism is required for a certain direction of operation, it may be necessary to cancel or restore the function of the mechanism. Further, the function of the automatic return mechanism may be canceled or restored when the object to be operated changes or depending on the operator's preference.

In such a case, in order to release or restore the automatic return mechanism in the conventional stay device, there was a problem in that the spring 15 and the return arm 14 had to be removed and reattached, which was a troublesome task.

Particularly when the functions of the two states levers are reversed, the replacement work is complicated and time-consuming.

[Means for solving problems]

The stay device for a radio-controlled device of the present invention includes a movable member that is rotatably supported and controls the rotation of a variable resistor, a stay lever connected to the movable member, and a stay lever that automatically returns the movable member to a neutral position. an automatic return mechanism, the automatic return mechanism comprising: an operation pin provided on the movable member; a return arm that abuts the operation pin and has one end rotatably fixed; and an elastic member that returns the movable member biased toward the operating pin side to a neutral position, in which the automatic return mechanism returns against the biasing force of the elastic member. a protrusion that releases the function of the automatic return mechanism by pressing the arm and separating it from the operating pin; and a protrusion that is formed integrally with the protrusion and that releases the function of the automatic return mechanism. and a contact member that contacts the movable member and provides resistance to rotation of the movable member when the movable member is rotated.

[Effect]

When the lid member is attached to the stay device, the projecting piece presses the return arm, resisting the biasing force of the elastic member, and separates the return arm from the operating pin of the movable member. Further, the contact member contacts the movable member.

The movable member to which the stay lever is attached is no longer subjected to the pressing force of the return arm urged by the elastic member, and resistance to rotation occurs due to the contact of the abutment member. Therefore, the movable member can be rotated to any desired position and stopped at that position by operating the states lever.

When the lid member is removed, the return arm immediately returns to its original position due to the elastic force of the elastic member and comes into contact with the operation pin of the movable member, so that the automatic return mechanism can be easily restored.

〔Example〕

FIGS. 1a and 1b are cross-sectional views of an embodiment in which a part of the structure is omitted.

This stake device 20 has a lid member 22, which is the main part of this embodiment, detachably attached to a stake device main body 21 having almost the same structure as the conventional one. Components that are substantially the same as those in the prior art are denoted by the same reference numerals as those used in [Prior Art], and explanations thereof will be omitted.

A protruding piece 23 is implanted at one end of the lid member 22, and a notch spring 24 as an abutting member is disposed at a portion facing the protruding piece 23. Further, screw holes are formed in the vicinity of the four corners of the lid member 22, and two of the screw holes facing each other are used to attach the lid member 2 to the support 21a of the stake device main body 21.
2 are screwed together.

When the lid member 22 is attached to the stay device main body 21, depending on how it is attached, the protrusion 23 may press the return arm 14 against the elastic force of the spring 15, as shown in FIG. 1a. The return arm 14 is separated from the operation pin 13. In this state, even if the states lever 9 is operated to rotate the movable frame 7, the return arm 14 will not come into contact with the operating pin 13. Therefore, the automatic return mechanism of the movable frame 7 and the states lever 9 by the return arm 14 is released, and the movable frame 7 and the states lever 9 can be stopped at any position.

On the other hand, when the protruding piece 23 pushes down the return arm 14, the notch spring 24
The notch portion 18 of the movable frame 7 is in contact with the notch portion 18 of the movable frame 7 to provide a certain degree of resistance to the rotational movement of the movable frame 7.

Therefore, the lid member 22 is attached to the stay device main body 2.
The automatic return mechanism of the states lever 9 can be brought into the released state by a simple operation of attaching it to the state lever 9. Furthermore, the notch spring 24 and the notch portion 1
8, the movable frame 7 and states lever 9 are now free.
It can be fixed more securely in any position.

On the other hand, when changing the stick device 20 of the embodiment from one having a fixing mechanism to one having an automatic return mechanism, the lid member 22 is removed from the stick device main body 21, or the lid member 22 is removed from the stick device main body 21, or as shown in FIG. The function of the states lever 9 can be changed very easily by simply rotating it by 90 degrees and attaching it.

Next, FIG. 2 and FIGS. 3a and 3b show other embodiments in which the automatic return mechanism has a different configuration.

In the second embodiment shown in FIG. 2, the return arm 25 is biased from the base to the tip of the states lever 9, and in the illustrated state,
The automatic return mechanism is released and the locking mechanism is working.

In this case, a key-shaped hook 27a is provided on the protruding piece 27 of the lid member 26 to suspend the return arm 25 in the middle so that the return arm 25 does not come into contact with the operation pin 28. At this time, the notch spring 29 as an abutting member is in contact with the notch portion 18, so that the stay lever 9 can be fixed at an arbitrary position. Similar to the first embodiment, when it is desired to operate the automatic return mechanism, the lid member 26 can be attached with the lid member 26 rotated by 90 degrees, or the lid member 26 can be removed.

In FIGS. 3a and 3b, the return arm 30 is composed of a pair of left and right arm members 30a and 30b.

When the states lever 9 is tilted to the left, the left arm member 30a is rotated by the operating pin 31.
At this time, the right arm member 30b comes into contact with a stopper 33 provided on the stake device main body 32 and does not rotate. When the states lever 9 is released, the left arm member 30a is pulled back by the spring 34 stretched between the left and right arm members 30a and 30b.
returns to its original state. The right arm member 30b also has a similar effect.

When the fixing mechanism is to be operated, the lid member 35 having the slightly wider protrusion 36 is attached to the stake device body 32 at a position rotated by 90° from the position shown in FIG. 3a. In this state, as shown in FIG. 3b, the projecting piece 36 is
The return arm 30 is inserted between the pins 31 and 31 so that the return arm 30 does not come into contact with the operating pin 31 even if the states lever 9 is rotated. On the other hand, a notch spring 37 serving as an abutting member provided on the lid member 35 abuts on the notch portion 18, so that the movable frame 7 and the stay lever 9 can be fixed at arbitrary positions. Note that the protrusions 23 and 36 can also be formed on a part other than the lid member, for example, on the main body of the stick device.

[Effect of idea]

According to the present invention, in a stay device having an automatic return mechanism, the automatic return mechanism can be released with an extremely simple operation, the stay lever can be held at a desired position, and the automatic return mechanism can be restored with a simple operation again. Therefore, there is an effect that the function of the stay lever of the stay device for radio-controlled equipment can be easily changed according to the needs of the user.

In addition, since both mechanisms can be selected as needed by simply attaching and detaching the lid member, there is no need to separately design and manufacture a stay device with an automatic return mechanism and a stay device with a fixing mechanism. , which is extremely advantageous from the viewpoint of cost reduction.
