Apparatus comprising a lower support structure having an upper surface, a circular lower rail which is mounted on the upper surface of the lower support structure and which is centered on a generally vertical axis, an upper structure having a lower surface, a circular upper rail which is mounted on the lower surface of the upper structure and which is centered on the axis, a plurality of rollers which are located between the upper and lower rails and which support the upper structure for rotation relative to the lower structure about the axis, the rollers being rotatable about respective generally horizontal axes intersecting the vertical axis at a common point, one of the rails including an inwardly facing surface defining a portion of a sphere centered on the point, and each of the rollers including an outwardly facing surface which engages the inwardly facing surface and which defines a portion of a sphere centered on the point.
Appareil comprenant une structure inférieure de support ayant une surface supérieure, un rail circulaire inférieur monté sur la surface supérieure de la structure inférieure de support, et qui est centré sur un axe généralement vertical, une structure supérieure ayant une surface inférieure, un rail supérieur circulaire qui est monté sur la surface inférieure de la structure supérieure et qui est centré sur l'axe. Une pluralité de galets sont disposés entre les rails supérieur et inférieur, et supportent la structure supérieure, autorisant le mouvement de rotation de cette dernière par rapport à la structure inférieure, autour de l'axe, les galets pouvant tourner autour de leurs axes respectifs généralement horizontaux, croisant l'axe vertical à un point commun, un des rails comprenant une surface tournée vers l'intérieur, définissant une partie d'une sphère centrée sur le point.
