摘要

Improvements in mechanical parachutes, for use as scaffolding or for the formation of scaffolds, of the type comprising a housing that houses a cart in which a suspension cable is coiled or uncoiled by means of a crank, characterized in that said reel is connected by means of a chain to a pinion, in whose axis a plate is mounted that serves as support to two diametrically opposed arched pieces that have for fixing by means of screws to the plate, two divergent grooves whose end directed in the direction of rotation corresponding to that of unwinding of the spool, is slightly curved inwards in order that said pieces separate during the unwinding operation, closing such operation when rubbing on the internal wall of a cylindrical box attached to the cover of the housing, box that is covered by a cover that is traversed by the pinion shaft, adjusting axis and cover each other so that the one is dragged by the rotation of the other by actuating the handle fixed to the cover, the two parts that form the brake being joined together by springs that join it when the unwinding operation stops.
