Patent

CA 2183072

The sunshade has a stand (2) on the mast (6) of which is guided an extendable and retractable jib (10). The outer end (12) of the jib (10) supports a shade (14). In addition, a strut (18) is articulated between the jib (10) and the top of the mast (6). The inner end (8) of the jib is moved along the mast by means of a jib drive (20). The shade (14) is opened and closed by means of a shade drive (24). To improve its kink and torsional stability the mast has a closed hollow cross-section containing spaced guide tracks on the outer side facing the jib (10) in which guide components of the inner end (8) of the jib (10) engage and are positively held transversely to the direction of movement.

L'invention concerne un parasol équipé d'un support (2) comprenant un poteau (6) sur lequel peut coulisser l'extrémité interne (8) d'un bras (10) extensible et rétractable, l'extrémité externe (12) du bras (10) supportant un parasol (14). En outre, un montant de raccordement (18) est monté articulé entre le bras (10) et l'extrémité supérieure du poteau (6). Un dispositif d'actionnement (20) du bras sert à déplacer l'extrémité interne (8) du bras le long du poteau. Un dispositif d'actionnement (24) du parasol déclenche l'ouverture et la fermeture du parasol (14). La stabilité au flambage et à la torsion du poteau est améliorée au moyen d'une section creuse et hermétique qui comprend du côté extérieur, face au bras (10), des glissières espacées dans lesquelles des éléments de guidage de l'extrémité interne (8) du bras (10) sont emboîtés et maintenus par liaison de forme, transversalement par rapport à la direction du déplacement.
