Patent

CA 2714433

The invention relates to a panel pivoting about an axis parallel to a side of the panel, which comprises a first continuous coating (1), a main structural frame of a composite stiffener (2, 3, 4, 5, 6) connected to the coating (1) and including a stiffening mesh (2, 3) with at least one pair of cross-shaped stiffeners each oriented in one of two directions, respectively, not parallel or perpendicular to the rotation axis. The two parts (3a, 3b) of each stiffener (3, 2) extending on either side of the centre of the cross are in structural continuity, and the two stiffeners (2, 3) each have an end located at one point (A, B, C) on the side of the panel parallel to the rotation axis, wherein the end is connected to a rigid member for connection to the rotation axis, the opposite end of at least one stiffener being blocked in rotation on a bearing point on the opposite side of the panel.

Le panneau, pivotant autour d'un axe parallèle à un côté du panneau, comporte un premier revêtement (1) composite, continu, une armature structurale principale de raidisseur composite (2, 3, 4, 5, 6) solidaire du revêtement (1), et comprenant un treillis de raidisseur (2, 3) à au moins une paire de raidisseurs en croix, orienté chacun dans l'une respectivement de deux directions ni parallèles, ni perpendiculaires à l'axe de rotation. Les deux parties (3a, 3b) de chaque raidisseur (3, 2) s 'étendant de part et d'autre du centre de la croix sont en continuité structurale et les deux raidisseurs (2, 3) ont chacun une extrémité en un point (A, B, C) sur le côté du panneau parallèle à l'axe de rotation et où l'extrémité est solidaire d'un organe rigide de liaison à l'axe de rotation, l'extrémité opposée d'au moins un raidisseur étant arrêtée en rotation sur un point d'appui sur un côté opposé du panneau.
