Abstract (en)
[origin: EP1972722A1] The gate has thin cores (2) each comprising a parabolic curve edge (B2) in a plane transversal to a flat shell skin plate (1). The core is widened towards its center and shrunk towards its ends. The core is pierced with disjointed recesses (20) that are configured for forming bands and bridges. The bands are respectively extended along the plate and the edge. The bridges connect the bands and extend between the adjacent recesses. A tubular stiffener (4) extends across the recesses of the cores.
