A mobile base device for a sun umbrella including a base cover. A bearing support is arranged inside the base cover and is hinged with a main lifting arm via a stiffened plate mounted thereon. An outer end of the main lifting arm is screwed to a lifting screw mounted on the bearing support via a lifting screw sleeve and an inner end of the main lifting arm is fixedly coupled to a set of secondary lifting arms through joints. A central portion of the set of secondary lifting arms is hinged with a set of stiffened plates mounted on the bearing support and a lower portion of the outer end of the set of secondary lifting arms is fixedly coupled to a set of casters. The lifting arms are hinged to the umbrella base via the bearing support and the lifting arms are enabled to move upwards or downwards by means of controlling the end of the main lifting arm by a handle and meanwhile allow the secondary lifting arms to drive the casters mounted thereon to drop or lift. Thus, the sun umbrella moves easily and rapidly when the casters touch the ground and the umbrella will be securely fixed when the casters lift and foot mats touch the ground. Such structure has the advantages of easy movement and fixation as well as practicality and convenience.
Un dispositif de base mobile pour un parasol comprenant un couvercle de base. Un support de palier est placé à lintérieur du couvercle de base et est articulé avec un bras élévateur principal à laide dune plaque rigide qui y est montée. Une extrémité extérieure du bras élévateur principal est vissée à une vis élévatrice montée sur le support de palier à laide dun manchon fileté élévateur et une extrémité intérieure du bras élévateur principal est couplée de manière fixe à un ensemble de bras élévateurs secondaires par lintermédiaire de joints. Une partie centrale de lensemble de bras élévateurs secondaires est articulée avec un ensemble de plaques rigides installées sur le support de palier et une partie inférieure de lextrémité extérieure de lensemble de bras élévateurs secondaires est couplée de manière fixe à un ensemble de roulettes. Les bras élévateurs sont articulés à la base du parasol par le support de palier et les bras élévateurs peuvent se déplacer vers le haut ou le bas au moyen dune commande de lextrémité du bras élévateur principal par une poignée et permettent en même temps aux bras élévateurs secondaires dentraîner labaissement ou lélévation des roulettes installées dessus. Ainsi, le parasol se déplace facilement et rapidement lorsque les roulettes touchent au sol et le parapluie sera solidement fixé lorsque les roulettes sélèvent et que les tapis de sol touchent le sol. Une telle structure possède les avantages dun mouvement et dune fixation faciles ainsi que laspect pratique et facile dutilisation.
