Abstract

When an aileron servo is driven, a repulsive force from a stabilizer controlled by an operating rod acts on the operating rod to bend, etc., and a displacement amount from the servo cannot be accurately transmitted to the stabilizer. There was such a problem. SOLUTION: An aileron servo 11 for controlling a stabilizer is provided on a frame 1 on which members necessary for flight such as an engine 2 and a main rotor 7 are attached, and a moving direction of an operating rod 11c controlled by the servo. This is a servo mounting structure for aileron of a helicopter toy slidably mounted in a parallel direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention controls a stabilizer of a helicopter toy, and tilts the helicopter toy in the left-right direction or moves a servo for the aileron for moving the helicopter toy in the left-right direction slidably with respect to the frame. The present invention relates to a servo mounting structure for an aileron of a helicopter toy to be mounted.

[0002]

2. Description of the Related Art A schematic structure of a helicopter toy will be described with reference to FIG. 1 is a frame, 2 is an engine mounted on the frame 1, 3 is a main gear rotated by the engine 2 via a gear group 31, 4 is a rotating shaft rotated by the main gear, 5 is a rotating shaft 4 A center hub 6 fitted and fixed to the center hub 6 is a yoke mounted at right angles to the center hub 5, and main rotors 7 are mounted at both ends.

[0003] Reference numeral 8 denotes a tail pipe fixed to the frame 1 via a fixing member 9, and 10 denotes a tail rotor attached to the rear end of the tail pipe 8, and the engine 2
It rotates via a belt or a rotating shaft by a further driving force.

A stabilizer (not shown) is mounted above the center hub 5, but an aileron servo 11 (hereinafter, referred to as a servo) for controlling the stabilizer.
The servo is simply attached to the frame 1 so as to swing freely. That is, as shown in FIG.
Numeral 1 is fixed to a triangular mounting bracket 11a, and the vertex of the mounting bracket 11a is pivotally supported by the frame 1 so as to be swingable.

[0005] Two operating rods 11c are attached to the plate 11b of the servo 11, and the tip of the operating rod 11c is connected to the stabilizer via a link mechanism 11d. When the servo 11 is driven, the operating rod 11c moves alternately in the left-right direction, so that the stabilizer is controlled via the link mechanism 11d, and the helicopter toy tilts in the left-right direction or moves in the left-right direction. It will be.

[0006]

By the way, when the above-mentioned servo 11 is driven to control the stabilizer via the operating rod 11c, the left and right movement of the operating rod 11c is controlled by a link mechanism 11d interposed between the operating rod 11c and the stabilizer. A repulsive force for rotating the servo 11 in the vertical direction as indicated by an arrow A and a repulsive force for moving the servo 11 in a horizontal direction as indicated by an arrow B act.

As a result, the servo 11 makes an oscillating motion as shown by the arrow C. This oscillating motion has a large repulsive force to move the servo 11 in the horizontal direction of the arrow B. As a result, a considerably large external force acts on the operating rod 11c due to the swing caused by the tilt angle, and the operating rod 11c is bent and the displacement amount of the operating rod c is accurately adjusted with respect to the stabilizer. There was a problem that communication was not possible.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to absorb a repulsive force for moving a servo in parallel with a frame and moving the servo in a horizontal direction. Another object of the present invention is to provide a servo mounting structure for an aileron of a helicopter toy capable of accurately transmitting a servo displacement to a stabilizer.

[0009]

SUMMARY OF THE INVENTION A servo mounting structure for an aileron of a helicopter toy according to the present invention achieves the above-mentioned object, and includes means for mounting members required for flight, such as an engine and a main rotor. An aileron servo for controlling the stabilizer is slidably mounted on the frame in a direction parallel to the moving direction of the operating rod controlled by the servo.

It is preferable that a guide rail made of a wear-resistant material is mounted on the frame, and the aileron servo is mounted on a base having a roller engaged with the guide rail.

The groove of the roller is formed in a V-shape,
And the portion of the guide rail that engages with the roller is a reverse V
Or a groove of the roller is formed in a U-shape, and a portion of the guide rail engaging with the roller is formed in an inverted U-shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a servo mounting structure for an aileron of a helicopter toy according to the present invention will be described below with reference to the drawings. The same reference numerals as those in the above-described conventional example denote the same members, and a description thereof will be omitted. A portion of the frame 1 where the servo 11 is mounted is a parallel guide portion 1a, and a guide rail 12 made of a wear-resistant synthetic resin or a metal plate is fixed to the parallel guide portion 1a by screws 12a.

Reference numeral 13 denotes a square base on which the servo 11 is mounted, and rollers 14 including bearings are mounted at four corners, and the rollers 14 are engaged with the guide rails 12. The roller 14 and the guide rail 1
2, as shown in FIG. 2, the peripheral surface of the roller 14 is formed in a V-shape in a side view, and the portion of the guide rail 12 engaged with the roller 14 is formed in an inverted V-shape. I have.

In the embodiment shown in FIG. 3,
The peripheral surface of the roller 14 is formed in a U shape in a side surface shape,
Further, a portion of the guide rail 12 that is engaged with the roller 14 is formed in an inverted U-shape.

With the servo mounting structure for ailerons of the present invention thus constructed, when the repulsive force in the direction of arrow B shown in FIG.
Since the base 13 on which is mounted is slidable by the rollers 14 and the guide rails 12, the base 13 moves to the position shown in FIG. 4A or moves to the position shown in FIG. Operating rod 11
Inconvenience such as bending due to excessive force acting on c can be prevented, and the displacement of the servo 11 can be accurately transmitted to the stabilizer.

When a small repulsive force in the direction of arrow A shown in FIG. 6 acts on the operating rod 11c,
Since the connecting portion 11e with the plate 11b is made of an elastic material such as rubber, the repulsive force in the direction of the arrow A is absorbed by the connecting portion 11e, and therefore, the servo 11
Is accurately transmitted to the stabilizer.

[0017]

As described above, according to the present invention, the aileron servo is slidable relative to the frame in the moving direction of the operating rod, so that even if a repulsive force acts on the operating rod due to the displacement of the servo. It can be absorbed by the movement of the servo itself, so that the operating rod does not bend due to the repulsive force, and the servo displacement can be accurately transmitted to the stabilizer.

Further, since the guide rail for guiding the rollers of the base on which the servo is mounted is made of an abrasion-resistant material, play is not caused even by repeated reciprocating movements of the base, so that the stabilizer can be mounted on the stabilizer. The displacement amount can be accurately transmitted over a long period of time, and the base rail can be attached and detached very easily by fixing the guide rail with screws.
