Abstract

Improved tilting door, that to the type of those constituted by a single leaf, related to the upper part of the frame by connecting rods, whose frame comprises a compensation device that pulls the lower end of the door, this end being guided by the jambs of the frame, is essentially characterized in that the compensating device comprising is constituted by a cylindrical helical tractor spring, arranged horizontally on the back of the frame, one of the ends of the spring being connected to a fixed point of said lintel, while its opposite end is coupled to the support of a mobile double pulley, which pulls simultaneously from the two branches of a cable that passing through a fixed pulley, located in the own lintel, return to a second double fixed pulley of the upper end of one of the jambs of the frame, to directly lower one of the branches of the cable to a stump d.1 lower end of the the door, while the opposite branch of the cable returns horizontally through the lintel to a third fixed pulley, from the upper end of the opposite jamb of the frame, to descend vertically and finally to a second lateral stump opposite the lower end of the door; with the perpendicularity of said collateral stumps of the end of the door respectively constituting axes of rotation of two chassis plates that include two wheels, one on each side of the spinning stump, whose wheels allow the sliding and tilting of the door, as long jambs of the frame.
