A caster assembly (30) that can be used with furniture to support the furniture and to make the furniture mobile. The caster assembly has a housing (34) with a stem (32) that extends upwardly to be attached to the particular piece of furniture. Within the housing is a plurality of spherical rollers (36) that are supported within the housing so as to be rotatable about their center points (52) and therefore can rotate in any direction as the furniture is moved. In the preferred embodiment, there are three spherical rollers that are all equidistant from the center line or longitudinal axis of the stem so that the weight of the furniture that bears down upon the stem is supported equally by the spherical rollers contacting the floor. As a further feature, a glide cup (38) is provided that can be readily attached and detached from the bottom of the housing and, when attached, the glide cup covers the spherical rollers and presents a flat, planar surface that contacts the floor.

L'invention concerne un système de roulettes convenant pour un meuble, destiné à supporter le meuble et à le rendre mobile. Ce système de roulettes comprend un logement doté d'une tige qui s'étend vers le haut et peut être fixée sur le meuble choisi. Le logement entoure une pluralité de roulettes sphériques montées dans ce dernier de manière à pouvoir tourner autour de leur centre, ce qui leur permet de tourner dans toutes les directions lorsque le meuble est déplacé. Dans la forme de réalisation préférée, cet ensemble comprend trois roulettes sphériques équidistantes de la ligne médiane ou axe longitudinal de la tige, de manière que le poids du meuble supporté par la tige est réparti de manière égale entre les roulettes sphériques entrant en contact avec le sol. Cet ensemble comprend en outre une coupelle patin, qui peut être facilement montée et démontée sur la partie inférieure du logement, et qui une fois en place recouvre les roulettes sphériques et présente une surface plane et régulière entrant en contact avec le sol.
