Abstract

L'invention concerne un chariot de ménage pouvant être déplacé en douceur dans tous les sens, même dans un passage étroit. Le chariot présente une haute résistance de charge, une grande stabilité et une esthétique si belle qu'il peut être utilisé même comme article d'ameublement. Le chariot est muni de roues et de dispositifs de fixation qui lui confèrent une utilité optimale. On décrit plus particulièrement un chariot équipé de roues fixées à une surface inférieure d'une structure du chariot (A), laquelle structure présente une épaisseur considérable telle qu'elle confère au chariot à la fois une hauteur totale basse et une belle esthétique. Au moins trois roulettes pivotantes sphériques (B) servent de roues et un procédé d'encastrage est mis en oeuvre pour encastrer les roulettes pivotantes sphériques (B) à l'intérieur de la structure du chariot (A). Chaque roulette pivotante sphérique (B) est confectionnée par formation d'au moins une projection annulaire (B2) sur une surface circonférencielle externe d'un élément cylindrique (B1), et par couverture d'un élément sphérique (B3) avec une enveloppe élastique externe (B5) ou fixation solide dudit élément sphérique avec un matériau élastique. Les dispositifs de fixation du chariot utilisent des pièces d'attache amovibles (C) du type à fixation horizontale pour fixer les roulettes pivotantes sphériques.
