专利汇可以提供Toy helicopter or the like专利检索，专利查询，专利分析的服务。并且The present disclosure relates to a toy helicopter construction which permits the helicopter to perform or function in a realistic manner. The structure includes a fuselage member having front, rear and intermediate portions with a rotor shaft swingably or pivotally connected to the intermediate portion and with a rotor construction rotatably connected to the shaft. The pivotal mounting of the shaft to the intermediate portion of the fuselage enables the shaft to be swung to a position generally in line with the fuselage when catapulting the helicopter into the air. The present disclosure also discloses a rotor which is of a one piece integral plastic construction and the plastic material is flexible so that it can function in the specific manner which is disclosed. As the helicopter reaches the top of its trajectory after having been catapulted into the air, the pivotal mounting of the rotor shaft enables the rotor shaft to assume a position generally at right angles to the extent of the fuselage, and the force of gravity causes the blades of the rotor to rotate the rotor and in their rotatative condition to assume a position approaching parallelism with the earth. After the helicopter has reached the ground on its downward flight, landing gear are provided to engage the ground. Wall means are provided at the intermediate portion of the fuselage so as to engage the rotor shaft and maintain the same in a realistic looking upright position.，下面是Toy helicopter or the like专利的具体信息内容。

权利要求

1. A toy helicopter or the like, including in combination a fuselage member having front and rear end portions and an intermediate portion, landing gear means comprising first and second ground engaging members, wall means on one of said front and rear end portions for launching said helicopter into the air, said one of said front and rear end portions on which said wall means is located being the portion adapted to be first launched into the air, a rotor shaft pivotally secured to said intermediate portion of said fuselage whereby said shaft may move from a position generally normal to the extent of said fuselage member to a position generally in line with the other one of said front and rear end portions opposite the location of said wall means for launching said helicoPter into the air, and a rotor rotatably carried by said rotor shaft.

2. A toy helicopter as claimed in claim 1, wherein said pivotal connection is located slightly toward said rear end portion from the center of gravity of said fuselage member.

3. A helicopter as claimed in claim 1, wherein said rotor is connected to said rotor shaft in such a manner that longitudinal movement between the two is permitted.

4. A helicopter as claimed in claim 1, wherein another wall means are provided on said intermediate portion for engagement with the rotor shaft and rotor combination to maintain said rotor shaft in said position generally normal to the extent of said fuselage.

5. A helicopter as claimed in claim 4, wherein said rotor comprises first and second thin, flexible, opposed and generally flat plastic blades.

6. A helicopter as claimed in claim 5, wherein when said first and second flat blades are folded together, the longitudinal axis of the blades are at a small acute angle to each other.

7. A helicopter as claimed in claim 6, wherein said first and second blades are made of a one piece member.

8. A helicopter as claimed in claim 7, wherein said first and second blades each have a widened portion thereon.

9. A helicopter as claimed in claim 7, wherein said first and second flat blades made of said one piece member are held in folded condition by positioning a connecting portion of the first and second blades into a trough shaped bracket and holding the connecting portion therein by another member placed on top of the connecting portion and located in the trough shaped bracket.

10. A helicopter as claimed in claim 9, wherein said first and second blades are held in a generally V-shape configuration with a given angle between the two blades in the inactive condition thereof and because of the inherent resiliency of the blades and the coaction thereof with the air in the descending condition of the helicopter from a vertical height, the angle between the two blades increases.

11. A toy helicopter or the like, including in combination a fuselage member having front and rear end portions and an intermediate portion, wall means on said front end portion of said fuselage member carrying a representation of a pilot of the helicopter, wall means on said rear end portion of said fuselage member for engagement with means for propelling the helicopter into the air a given vertical height in the direction of said rear end portion of said fuselage, landing gear means comprising first and second ground engaging members connected to said intermediate portion of said fuselage member, a rotor shaft pivotally secured to said intermediate portion of said fuselage whereby said shaft may move from a position generally in line with said front end portion of said fuselage member to a position generally normal to the extent of said fuselage and a rotor rotatably carried by said rotor shaft.

12. A toy helicopter as claimed in claim 11, wehrein said pivotal connection is located slightly toward said rear end portion from the center of gravity of said fuselage member.

13. A helicopter as claimed in claim 11, wherein said rotor is connected to said rotor shaft in such a manner that longitudinal movement between the two is permitted.

14. A helicopter as claimed in claim 11, wherein another wall means are provided on said intermediate portion for engagement with the rotor shaft and rotor combination to maintain said rotor in said position generally normal to the extent of said fuselage.

15. A helicopter as claimed in claim 14, wherein said rotor comprises first and second thin, flexible, opposed and generally flat plastic blades.

16. A helicopter as claimed in claim 15, wherein when said first and second flat blades are folded together, the longitudinal axis of the blades are at a small acute angle to each other.

17. A helicopter as claimed in claim 16, wherein said first and second blades are made of a one piece member.

18. A helicopter as claimed in claiM 17, wherein said first and second blades each have a widened portion thereon.
