Abstract

L'invention concerne des accessoires d'artistes et est destiné à s'utiliser dans des locaux ou à l'extérieur. Le résultat technique consiste à améliorer le confort d'utilisation du chevalet de peintre, à simplification de la conception, à assurer sa compacité dans les positions repliées et de travail, à élargir les fonctionnalités, à assurer le caractère polyvalent de son utilisation dans des locaux ou dans des espaces ouverts. Le chevalet de peintre comprend une montant vertical monté sur un appuie de base, une planche, un moyen pour disposer des objets, des lattes de raccordement qui relient la planche et le moyen pour disposer des objets. La liaison des lattes de raccordement à la planche est réalisée de manière à pouvoir assure la réorientation de l'articulation fonctionnelle autour de l'axe horizontal qui passe par les zones d'extrémité des lattes de raccordement du côté de la planche et avec une possibilité de fixation de ladite articulation. La planche est montée par le côté arrière sur un montant vertical de manière à permettre la rotation autour d'un axe horizontal à 180° et sa fixation dans n'importe quelle position. La réorientation de la planche, de l'articulation fonctionnelle et du moyen pour disposer des objets assurent une position repliée désirée ou la position de travail du chevalet de peintre. Le montant vertical a été réalisé de manière à pouvoir être régulé en hauteur.
