Publication number: 20110143628Abstract: A flying vehicle in accordance to an embodiment of the present invention includes a propeller control mechanism for flying the vehicle. The propeller control mechanism includes a propeller having a center shaft for connecting to the drive shaft; first and second propeller blades extending from the center shaft; and a control mechanism including a first linkage connecting the center shaft to the first propeller blade and a second linkage connecting the center shaft to a region defined on the propeller, wherein a change in a driving torque of the drive shaft causes the first linkage and the second linkage to change the pitch and height of the propeller blades while substantially unchanging the tip path plane of the propeller blades.Type: ApplicationFiled: February 10, 2011Publication date: June 16, 2011Inventor: Steven Davis

Patent number: 7946526Abstract: A rotary-wing apparatus that is aeronautically stable, easy to fly with a multidimensional control, small size, and safe to fly and low cost to produce. The rotary-wing apparatus includes a coaxial, counter rotating rotor drive providing lifting power with an inherent aeronautical stability; auxiliary propellers that face the direction of flight and are located on opposite sides of said coaxial rotary-wing apparatus and enable flying forwards, backwards and perform yawing. The rotary-wing coaxial helicopter toy is remotely controlled and safe to fly in doors and out doors, while performing exciting maneuvers even by untrained kids.Type: GrantFiled: November 2, 2005Date of Patent: May 24, 2011Inventor: Nachman Zimet

Publication number: 20110065351Abstract: A remote controlled transformable toy vehicle that is remotely transformable from a standing position to a flying position, where the toy performs like a helicopter and also to a driving position, where the toy performs like a wheeled vehicle. Transformations are carried out on-the-fly by remote control and the toy vehicle has the ability to maintain proper center of gravity for stable flight, takeoff and landing. Also provided is a remotely controlled toy vehicle that is driven by a rotating blade system so as to both drive over the ground and hover or fly in the air.Type: ApplicationFiled: September 17, 2010Publication date: March 17, 2011Applicant: Spin Master Ltd.Inventors: Jeff CORSIGLIA, Charles SINK, Mark LADISLAO

Patent number: 7883392Abstract: A toy helicopter, in accordance with the present disclosure, includes a body having a longitudinal length and a main rotor. There is an element movable along the longitudinal length. The element allows a user to selectively adjust the location of the center of gravity of a toy helicopter by moving the element along the longitudinal length, thereby changing the velocity of the helicopter.Type: GrantFiled: August 4, 2008Date of Patent: February 8, 2011Assignee: Silverlit Toys Manufactory Ltd.Inventors: Alexander Jozef Magdalena Van de Rostyne, Kwok Leung Wong

Publication number: 20100178836Abstract: A single rotor model helicopter is provided, comprising a spindle, a rotor clamp disposed on the spindle, a pair of rotor blades disposed on the rotor clamp, and a pair of hybrid control rocker arms. The helicopter further includes an operating system and a balancing system. The pair of hybrid control rocker arms are disposed on both sides of the rotor clamp respectively and rotatably connected to a pitch control rocker arm through each axial hole located on a center of each hybrid control rocker arm, so as to control attack angles of the rotor blades. Each hybrid control rocker arm has two control points. A first pair of control points diagonally opposite each other in the pair of hybrid control rocker arms are controlled by a cyclic torque transmitted from the operating system, and a second pair of control points diagonally opposite each other are controlled by the balancing system.Type: ApplicationFiled: March 25, 2010Publication date: July 15, 2010Applicant: SHANGHAI NINE EAGLES ELECTRONIC TECHNOLOGY CO., LTD.Inventors: Guochuan HUANG, Yuchen Wu, Yizhen Yu, Huanzhong Ding

Publication number: 20100130093Abstract: A remote control toy helicopter has a main rotor and an auxiliary rotor both driven by a rotor shaft. The auxiliary rotor has elongated elements at an acute angle relative to blades of the main rotor. A control system is provided that includes an actuator for engaging with a control assembly depending from the auxiliary rotor. The inter-engagement of the actuator and the control assembly effects change in the angle of incidence of the elongated elements of the auxiliary rotor. The interaction occurs when the assembly engages with the actuator by a depending arm associated with the assembly.Type: ApplicationFiled: November 25, 2008Publication date: May 27, 2010Applicant: SILVERLIT TOYS MANUFACTORY LTD.Inventors: Alexander Jozef Magdalena Van de Rostyne, Chi Pok Billy WAI
