Abstract

Crane for perfected toy vehicles, comprising a rotating base, around a vertical axis, on the platform of the vehicle, is essentially characterized in that the arm comprising, is constituted by two hollow bodies, of similar sections, one envelope and the other wrapped, of which the wrapped is longitudinally displaced by the shell by means of a spindle axially occluded between them, whose spindle, with a wide thread pitch, passes through a nut formed by a closing plate of the rear end of the body wrapped in the arm and rotates free on another plate of the enclosing body, the rear end of the spindle being axially joined to a toothed crown with side teeth, the crown of which engages with a pinion coined on the axis of a manually operated crank; while said arm, besides being articulated transversally by its extremity to the base, is related to the latter through a telescopic arm, acting tornapuntos whose wrapped section constitutes a rack of saw teeth, while the section wrapped it has a lever-ratchet, whose pulsation achieves the recovery or retraction of the wrapped section; so that the angular rotation of elevation of the arm of the crane is obtained gradually, by means of manual traction of the arm, which is braked by the ratchet tornapoints, while the extensibility of the arm of the crane is made by means of the crank and spindle referred to .
