Abstract:
In one embodiment of the invention, a captive propelled model is provided comprising a balancing member having a pivoting pin disposed between two ends of the balancing member. A figurine having an actuator and at least one actuable member is disposed near one end of the balancing member, and a counterweight is disposed near the opposite end. A platform for the device includes wiring for connecting a power supply to the actuator. In a further embodiment of the invention, a conductive member is disposed so as to receive the pivoting pin and thereby establish an axis of rotation about which the balancing member rotates when propelled by the actuable member. The conductive surface is also in contact with a drag-line or the like that is suspended from the balancing member to establish an electrical ground for the power supply circuit. In a further embodiment of the invention, a captive propelled model further comprises a remote controller, a switch having a receiver to receive a control signal from the remote controller, and associated wiring and connections so that an operator can control the device remotely.

Abstract:
A rotating toy may then include a hub having a central axis and a lower portion; a plurality of counter rotating blades extending outwardly from the lower portion of the hub, the plurality of counter rotating blades having a tip connected to an outer ring; a single means for rotating the hub and blades sufficiently quickly to generate a major portion of the lift generated by the aircraft through the single rotating means; and the hub having an upper portion above the plurality of counter rotating blades and above the single rotating means such that the aircraft includes a center of gravity above the plurality of counter rotating blades to provide a self-stabilizing rotating toy. In furtherance thereto the single rotating means may be secured on the central axis and positioned below the counter rotating blades.
Abstract:
A method and apparatus for controlling a powered craft in flight by an unsupported hand held control element. The position and attitude of the craft are controlled by the position and attitude of the control element. The position and attitude of the craft is determined with respect to a straight line between the controller and the craft, for example a beam of radiation. The controller and the craft are both provided with transducers comprising emitter and/or detector arrays in communication with one another.
Abstract:
A remote controlled aircraft (100) has a center member (112) and a steering assembly. The steering assembly comprises a carriage (120), a remote control motor (121), a center member (112) and a connecting arm. The carriage (120) pivotably is attached to the center member (112). The remote control motor has a control arm (122) and is disposed within the carriage (120). The center member arm (830) has a first end and a second end. The first end of the center member arm is fixedly attached to the center member (812). The center member (812) and the center member arm (830) is arranged in a non-parallel manner. The connecting arm (840) has a first end and a second end. The first end of the connecting arm (840) is pivotably attached to the second end of the center member arm (830). The second end of the connecting arm (840) is pivotably attached to the control arm (822) of the remote control motor (821).
Abstract:
A throw and fly device used as a toy, for recreational purposes and as sporting equipment. In a device constructed according to the present invention the base-part (1), the axle (2) and the flange (3) form a spool for the string (4). When thrown the device glides and the string (4) unwinds from the said spool accelerating the speed of rotation of the device. The energy thereby stored in the form of rotational movement returns the device back to the user and the device is ready for a new flight.
Abstract:
The invention relates to a tethered aircraft and the control of such tethered aircrafts, for example for use in Airborne Wind Energy (AWE) applications. Tethered aircrafts can use bridles (15) distributed along the span-direction to improve the structural integrity and reduce weight, but this results in them becoming roll-limited to some extent, making normal banking and rolling inapplicable to yaw the aircraft. The invention provides solutions to yaw a roll-limited aircraft and to control the degree of roll-limitation from the bridles (15), which render the rudder and lo several other vertical control surfaces unnecessary in turning and controlling yaw of the aircraft. These can therefore be omitted with the advantages of less drag, less weight and simpler design.
Abstract:
A carrier (80, 280) and a conventional toy vehicle (70) have structures (78, 86, 286) to releasably connect the two together. The carrier is configured to support the vehicle to run along a T shaped portion (42b, 42a) of monorail track (40). The carrier has a main housing (82, 282) having the mating structure and a through channel (84, 284) on upper (82a, 282a) and lower (82b, 282b) sides. Rollers (94, 294) support the carrier to move on the upper running surface (43) of the track while other structures (97, 297) extend beneath the running surface to capture the surface in the through channel. Weights (92, 292) are supported from the main housing in legs (88, 288) below the main housing, through channel and running surface.
Abstract:
A balloon toy includes a balloon; a balloon string tethered to the balloon; and a balloon raising and lowering assembly including: a housing including a handle; a balloon string reel rotatably carried within the housing and carrying the balloon string; an electric motor carried within the housing; a power source carried within the housing for powering the electric motor; a gear assembly including a plurality of gears carried with the housing and operable coupling the electric motor to the balloon string reel for driving rotation of the balloon string reel; a biasing member including a biasing force that urges the gear assembly together so that the plurality of gears are engaged for driving rotation of the balloon string reel for drawing in the balloon string and helium-field balloon and allows the plurality of gears to slip relative to each other if tension on the balloon string is too high.
