Abstract

Improved toy helicopter, which can be operated by a rope mechanism, or by a micromotor powered by batteries, as appropriate, is characterized because on its drive shaft has mounted a cam that rotates it transmits a horizontal, rectilinear and alternately directed in opposite directions to a laminar frame at the end of which is attached a lever that, being articulated by an intermediate point of its extension to a fixed point, plays superiorly with a link linked in turn to another similar one that by its free end is articulated to a doll in the form of a pilot, looking like the two rods mentioned on the arm and forearm of such a pilot, it being foreseen that the aforementioned drive shaft incorporates a toothed crown that gives movement, through a pinion and crown, to the vertical axis the propeller, whose axis partly possesses an elbow rod which when rotated opens so that its lower part collides with the helicopter walls, producing a sound simulator of a motor, it is further provided that the chassis carrying mechanisms is provided with an axis, which has a helical spring on the area of the upper indicated chassis and whose lower part ends after a bend in a wheel, which can be positioned in several positions, thanks to some laces to the effect that the helicopter box is provided.
