<p>The device has a longitudinal, homogenous and flexible elastic transmission unit (OE) e.g. draw-spring, formed of a continuous part extending on each panel until positioning and fixation unit, where the positioning and fixation unit comprises top and bottom bolts. The panel forms a leaf hatch. A guiding unit extends on the length of the transmission unit and guides translation movement of the transmission unit for opposing deformation of the transmission unit by flexion on the length of each section that forms a leaf hatch in closed position.</p> |
