Abstract:
A toy helicopter assembly having a guard that prevents the vertical lift rotors of the toy helicopter from inadvertently contacting any object while spinning. The toy helicopter has a body that includes a fuselage and landing gear. A drive shaft extends upwardly from the fuselage. A least one rotor is connected to the driveshaft. Each rotor is rotated by the driveshaft in a circular path through a predetermined plane of rotation. A plurality of loop structures are attached to the toy helicopter. The loop structures extend along curved paths, therein creating a guarded area within the curved paths. The loop structures are oriented so that at least part of the circular path that is traversed by the rotors extends through the guarded area.
