The invention provides a mechanism suitable for lifting an appliance, particularly a domestic appliance. The mechanism (2) comprises a generally cylindrical body (8) having a wall (50) and a longitudinal axis (16) which extends in an upward direction. At least one rolling support member (20) is rotatably mounted on an axle (100) beneath the body (8). A housing (6) having a generally cylindrical socket portion (200) with an inner surface (208) receives the body (8). The wall (50) and the inner surface (208) incorporate opposing camming surfaces (62) (210) such that when the body (8) is rotated about the axis (16) with respect to the socket portion (200), the camming surfaces (62) (210) co-operate. The housing (6) is moved axially with respect to the body (8) and away from the at least one rolling support member (20). The mechanism (2) lifts the appliance (400) from a resting position and into an elevated position ready for manoeuvring. The invention further provides a mechanism (2) suitable for steering an appliance (400).Th e mechanism (2) comprises a housing (6) and a body 88). The body (8) is connected to the housing (6) so as to allow relative rotation therebetween about a vertical axis (16). At least one rolling support member (20) is mounted on a horizontal axle (100), the axle (100) being mounted on the body (8) and located so as to intersect the vertical axis (16). A handle portion (10) is connected to the body (8) and extends radially outwardly from the vertical axis (16). This arrangement allows the consumer to steer the appliance (400) in an elevated position, in a range of directions, including but not limited to forwards and backwards.

L'invention concerne un mécanisme servant à soulever un appareil, notamment un appareil électroménager. Le mécanisme (2) selon l'invention comprend un corps pratiquement cylindrique (8) présentant une paroi (50) et un axe longitudinal (16) s'étendant vers le haut. Au moins un élément support roulant (20) est monté rotatif sur un essieu (100) en dessous du corps (8). Un boîtier (6) ayant une partie douille pratiquement cylindrique (200) munie d'une surface intérieure (208) reçoit le corps (8). La paroi (50) et la surface intérieure (208) comportent des surfaces en came antagonistes (62, 210) de sorte que lorsque le corps (8) tourne autour de l'axe (16) par rapport à la partie douille (200), les surfaces en came (62, 210) coopèrent. Le boîtier (6) est déplacé axialement par rapport au corps (8) avec éloignement de l'élément support roulant (20). Le mécanisme (2) soulève l'appareil (400) d'une position de repos dans une position élevée permettant la manoeuvre. L'invention concerne également un mécanisme (2) servant à diriger un appareil (400). Le mécanisme (2) selon l'invention comprend un boîtier (6) et un corps (8). Le corps (8) est relié au boîtier (6) de manière à permettre une rotation relative entre eux autour d'un axe vertical (16). Au moins un élément support roulant (20) est monté sur un essieu horizontal (100), l'essieu (100) étant monté sur le corps (8) et placé de façon à couper l'axe vertical (16). Une partie manche (10) raccordée au corps (8) s'étend radialement vers l'extérieur en partant de l'axe vertical (16). Cette disposition permet à l'utilisateur de diriger l'appareil (400) en position élevée dans une série de directions, notamment mais pas seulement vers l'avant et vers l'arrière.
