Abstract

Improvements in the mechanical arrangements for driving articulated doors, characterized in that in a set of two upper and lower leaves, articulated with each other and the upper one with the lintel of the door, the lower leaf has on its side edges a sliding lug on a guide fixed vertical, said sheet also having on its face through which the folding protruding from the door in the open position takes place, two lateral devices at equal height, formed by a grooved rail integral with the leaf with an inclination projecting from the upper end, a pivot joined to a slider sliding in a vertical guide adjacent to said guide of the lower sheet itself penetrates into the slot, so that in the closed door position, the pivots of the slides are at the lower end of its slot, while when the runners are lifted by other mechanical or mechanical means, their pivots slide, in the grooves of the s rails, which accentuate their inclination by the forced parallel displacement of the aforementioned lugs and pivots, forcing the lower blade to perform the same movement as it is camped, making this lower sheet that the upper sheet perform another tilt in opposite direction, until said pivots reach the opposite end inside the grooves of the rails, with which the lower sheet is substantially horizontal in its position of maximum elevation to open door, taking place in the opposite direction the previous operations for the route of the leaves in the closing action of the door.
