Abstract
Control of a toy flying toy plane comprises providing the plane having a motor and propeller and a separate remote controller for use by a player of the toy. The plane includes a flexible, foldable wing and a fuselage below the wing. The fuselage supports at least one propulsion unit and the fuselage is removably locatable relative to the wing. A signal is sent from a transmitter with the toy to the controller. A variation in intensity of the received signal to the toy being from the controller. The controller transmits a signal to the toy according to the desired action of the player and thereby to cause the flying toy to move as required.
Claims18
A flying toy airplane comprising:
- a wing formed of a deformable or foldable material and having a centrally disposed longitudinal ridge downwardly depending from the wing dividing the wing into two halves, the wing having two ends, the wing being supported by a fuselage completely beneath the wing releasably fastened to the ridge, the wing extending outward above opposite lateral sides of the fuselage beneath the wing;
- a first propulsion unit, having a first motor and a first propeller rotatable by the first motor, mounted on one of the lateral sides of the fuselage beneath the wing;
- a second propulsion unit, having a second motor and a second propeller rotatable by the second motor, the second propulsion unit being mounted on the other opposite lateral side of the fuselage beneath the wing;
- and
- a pair of clip and lock units for mounting the fuselage to the ridge, each clip when closed being for lightly holding the fuselage to the airplane, and being releasable and closable under finger pressure in different longitudinal positions relative to the airplane to thereby adjust the center of gravity of the airplane easily by shifting the fuselage forwardly or backwardly along the ridge forming a longitudinal axis of the airplane, a first one of the clip and lock units located at a front end of the fuselage and a second one of the pair of clip and lock units located at a rear end of the fuselage.
A flying toy airplane comprising:
- a wing formed of a deformable or foldable material and having a centrally disposed longitudinal ridge downwardly depending from the wing dividing the wing into two halves, the wing having two ends, the wing being supported by a fuselage completely beneath the wing releasably fastened to the ridge, the wing extending outward above opposite lateral sides of the fuselage beneath the wing;
- a first propulsion unit, having a first motor and a first propeller rotatable by the first motor, mounted on one of the lateral sides of the fuselage beneath the wing;
- a second propulsion unit, having a second motor and a second propeller rotatable by the second motor, the second propulsion unit being mounted on the other opposite lateral side of the fuselage beneath the wing;
- and
- a pair of clip and lock units for mounting the fuselage to the ridge, each clip when closed being for lightly holding the fuselage to the airplane, and being releasable and closable under finger pressure in different longitudinal positions relative to the airplane to thereby adjust the center of gravity of the airplane easily by shifting the fuselage forwardly or backwardly along the ridge forming a longitudinal axis of the airplane, a first one of the pair of clip and lock units located at a front end of the fuselage and a second one of the pair of clip and lock units located at a rear end of the fuselage, thereby effecting a relatively firm mounting to reduce the risk of fuselage dislocation in the event of impact of the plane on the ground, including a laterally directed spreader located across each half of the wing, the spreader providing wing rigidity and maintaining a dihedral angle of each wing, the spreader being above each wing and the spreader having at a least two limbs depending in a lateral direction from the spreader, the limbs being relatively spaced apart, and being for location with the fuselage and the ridge and for being releasably lockable in location with the pair of clip and lock units.
A flying toy airplane comprising a wing formed of a deformable or foldable material and including a downwardly depending longitudinal ridge centrally disposed from the wing supported by a fuselage completely beneath the wing releasably fastened to the ridge;
- a first propulsion unit having a single motor and a propeller rotatable by the single motor mounted on the fuselage beneath the wing;
- a pair of clip and lock units for mounting the fuselage to the ridge, each clip when closed being for lightly holding the fuselage to the airplane, and being releasable and closable under finger pressure in different longitudinal positions relative to the airplane to thereby adjust the center of gravity of the airplane easily by shifting the fuselage forwardly or backwardly along the ridge forming a longitudinal axis of the airplane, a first one of the clip and lock units located at a front end of the fuselage and a second one of the pair of clip and lock units located at a rear end of the fuselage;
- a rudder fastened to the fuselage;
- and
- a rudder control mechanism to support pitch and yaw control.
A fuselage for a flying toy airplane having a wing for supporting the fuselage entirely beneath the wing, the wing extending outward above and from opposite sides of the fuselage, the wing including a downwardly depending longitudinal ridge centrally disposed from the wing;
- the fuselage including a first propulsion unit attached to the fuselage located beneath the wing, having a first motor and a first propeller rotatable by the first motor;
- and
- a pair of clip and lock units for mounting the fuselage to the ridge, each clip when closed being for lightly holding the fuselage to the airplane, and being releasable and closable under finger pressure in different longitudinal positions relative to the airplane to thereby adjust the center of gravity of the airplane easily by shifting the fuselage forwardly or backwardly along the ridge forming a longitudinal axis of the airplane, a first one of the clip and lock units located at a front end of the fuselage and a second one of the pair of clip and lock units located at a rear end of the fuselage.
