Description

[Detailed description of the invention] [Industrial application field] This invention relates to a toy helicopter that is installed and used outdoors where the wind blows.

[Conventional technology]

Conventional helicopter toys are constructed so that the rotor blades and pilot figure are operated by electric or spring-type drive devices.

[The problem that the idea aims to solve]

Since the conventional helicopter toy uses an electric or spring-type drive device, it has the drawback of being complicated and expensive, and it also has the problem that it cannot be used as a wind vane even if it is installed outdoors where the wind blows. It was hot.

The purpose of this invention is that it can be installed outdoors where the wind blows and can be used as a wind vane.When used, the rotor of the wind cup structure rotates with the wind, and the pilot doll controls the helicopter. The purpose of the present invention is to provide a highly entertaining helicopter toy with a relatively simple structure and an interesting movement similar to that of a helicopter.

[Means to solve the problem]

In order to achieve the above-mentioned purpose, this invention supports the helicopter body on the upper end of the main body support shaft so as to rotate in the direction of the wind, so that it can be installed outdoors where the wind blows, and the helicopter body can be operated A rotating main shaft is pivotally supported in the chamber forming part so as to rotate around a vertical axis, and a wind cup structure rotor blade is attached to the upper end of this rotating main shaft to rotate when receiving wind;
A doll actuating cam having a flange-shaped cam portion obliquely inclined with respect to the shaft center is fixed to the lower end of the main rotating shaft, and is rotated in the vertical direction to a position near the cam in the cockpit shaping portion of the main body. Support the pilot doll,
This pilot doll is characterized in that it can be rotated vertically by rotating a cam.

[Effect]

The toy helicopter with the above configuration is installed and used outdoors where the wind blows, and since the helicopter body rotates in the direction of the wind and the rotor blades are rotated by the wind, it can be used as a wind vane. Also, when this is used, the pilot doll rotates up and down by the rotation of the cam, making interesting movements similar to those of piloting a helicopter.

〔Example〕

Hereinafter, the structure of a toy helicopter according to an embodiment of this invention will be explained in detail with reference to the drawings. In the figure, 1 is a main body support shaft fixed to a windy place such as a balcony, and 2 is the upper end of the main body support shaft 1. The helicopter body 2 is supported by bearings 3 and 4 so as to rotate in the direction of the wind. The helicopter body 2 has a cockpit shaping section 5 and a vertical tail fin 6 forming a wind direction plate. is a rotating main shaft 10 supported by bearings 7 and 8 so as to rotate around a vertical axis.
is provided.

Reference numeral 11 denotes a rotor blade having a wind cup structure that is attached to the upper end of the main shaft 10 and rotates in response to the wind. It is composed of a plurality of airfoil-shaped wind cups 12 which receive the wind and whose base ends are inserted and fixed into the core 9. Reference numeral 13 denotes a doll actuating cam fixed to the lower end of the rotating main shaft 10, and this doll actuating cam 13 is a composite cam having a flange-shaped cam part 14 that is inclined at an angle of about 70 degrees with respect to the axis. It is made of resin molded product.

Reference numeral 15 indicates a position near the cam in the cockpit molding part 5 of the main body 1 (internal protruding bracket 2 of the cockpit molding part 5).
The pilot doll 15 is pivotally supported by a protruding pin 16 so as to be rotatable in the vertical direction at the upper end position of the doll operating cam 13. The arm part 1 rotates the entire doll clockwise in FIG. 1 so that the cam engaging part 15 is always in contact with the lower surface of the cam part 14
8 and a foot portion 19. In addition, 20 in the figure is a doll retaining cap fitted onto the protruding pin 16 of the pilot doll 15.

Therefore, the helicopter toy having the above structure is installed and used outdoors where the wind blows, and when the wind blows, the helicopter main body 2 rotates in the direction of the wind using the main body support shaft 1 as a fulcrum, causing the rotation of the wind cup structure. The blades 11 are rotated by wind force. The rotation of the rotating blade 11 by the wind force rotates the main shaft 10 and the doll actuating cam 13, and the rotation of the doll actuating cam 13 causes the pilot doll 15 to move around the pin 16 as shown in the solid line and the imaginary line in FIG. It operates by rotating vertically as shown in .

[Effect of idea]

Since the helicopter toy of this invention has the above-mentioned structure, it can be installed outdoors where the wind blows and be used as a wind vane. It is possible to provide a highly entertaining helicopter toy with a relatively simple structure that rotates and makes interesting movements as if the pilot doll is piloting a helicopter.
