Automatically telescopic wind bracing system (ATW system) for roller doors, windbreaks and similar movable surface elements

Abstract

A mechanically telescopic wind bracing system for a roller door or windbreak system with a roll-up door curtain, a lower end profile connected to the door curtain, and a diagonal brace arranged between an upper mounting area of ​​the system and the lower end profile, characterized in that the diagonal brace comprises a continuous outer tube and an inner tube slidably guided directly in the outer tube, wherein the outer tube and the inner tube form a tube-in-tube telescope without a central connector arranged between the tubes, that the diagonal brace is pivotably mounted at its upper end by means of an upper articulated bearing and at its lower end by means of a lower articulated bearing, and that the length and angular position of the diagonal brace change mechanically through the opening and closing movement of the door curtain.
