A magnetically levitating door is disclosed herein. The door may have a magnet that is repelled from a magnet of a track. The track may be disposed adjacent to a door opening. The track may have ball bearings to maintain vertical alignment of the magnets used to levitate the door off of the track.

The track may have a stabilizing roller to maintain vertical alignment of the magnets used to levitate the door off of the track.

A guide (10) for a liftable sliding leaf comprises at least two guide bars (14, 16), a first bar (14) of which can be connected movably to a support (24), fixed with respect to the leaf, and a second bar (16) can be connected integrally to a top part (12) of the leaf (11) so that both the bars (14, 16) are movable in a vertical plane.

A supporting device (MC) is described to slidingly support, and linearly move along an axis (X), an object such as e.g. a leaf. A magnetic return force generated by the cooperation of a magnetic flux generator (54, 56) and an element (10) reactive to the magnetic field, develops. The element is able to slide relative to the axis (X) during the movement of the object, and has a cross-section (62) which, seen in a plane orthogonal to the axis (X), has a width that varies along the length of the first element (10) parallelly to said axis (X).

A magnetically levitating door is disclosed herein. The door may have a bracket having a magnet that is repelled from a magnet of a track. The magnet field of the bracket and the magnet field of the track may have different widths. The track may be disposed adjacent to a door opening. The bracket may have a guard in slidable engagement with the track to limit lateral movement of the magnet of the bracket disposed above and repelling the magnet of the track to levitate the door off of the track while preventing excessive lateral forces on the guard. The bracket may have at least one guide in slidable engagement with the track to secure the engagement of the bracket to the track and maintain vertical alignment of the bracket to the track.

A lifting system (11) for a liftable sliding leaf (10) comprises a lifting mechanism (16) which can be connected to a top part (12a) of the leaf (10), said lifting mechanism (16) being able to move between a first configuration and a second configuration where the leaf may slide or be locked, and a control member (12), which can be located on the fixed frame of the door and can be connected to the lifting mechanism (16) so as to switch it between the two configurations.

The present invention relates to a non-contact power transmission structure for a sliding door on a vehicle, the structure controlling opening/closing of the sliding door by generating electromagnetic induction energy. The non-contact power transmission structure for a sliding door includes: a rail disposed longitudinally on a side of a vehicle to guide a sliding door; a transmission coil disposed in the rail; and a roller assembly disposed on the sliding door to move along the rail, in which the roller assembly includes: a roller disposed on the sliding door so that the roller assembly moves along the rail; and a reception coil corresponding to at least a portion of the transmission coil, in which the reception coil generates electromagnetic induction electric energy to open and close the sliding door, using electric energy generated at the transmission coil.
