Abstract

Retention mechanism for doors, characterized by comprising an elongated box in which a chamber is formed, a piston mounted in a vault inside the chamber and provided with an end wall, a rack formed axially on the exterior surface of the piston, means of displacement to move the piston in one direction, valve means to allow the circulation of a hydraulic fluid from the chamber and from one side of the piston end wall to the other side thereof as the piston moves in the direction opposite, passage means for restricting the flow of hydraulic fluid from the chamber and from the other side of the end wall of the piston to one side thereof as the piston moves in one direction, a pinion shaft rotatably mounted in the box and extending through it perpendicular to the axis of the chamber, a pinion attached to the pinion shaft and provided with a toothed portion suitable for engagement engagement with the piston rack, whose toothed portion covers only the part of the circumference of the pinion which corresponds to the total turning portion of the door, which pinion is provided, in addition to a plurality of axial grooves in the periphery adjacent to the the toothed portion for receiving the edge of the end tooth of the rack, the axial grooves being of less depth than the spaces formed between the teeth of the toothed portion so that another rotation of the pinion shaft after the toothed portion thereof has disengaged from the zipper, results in the firm retention of the pinion by the end tooth of the rack, so that the door is retained in stages in any gradual position within the remaining portion of the total door turn.
