Definitions

• the invention relates to a sliding door with at least one lift-and-slide sash, which is arranged to be vertically height-adjustable and horizontally movable relative to a frame.
• At least one magnetic arrangement with at least one magnet is arranged in the frame and in the at least one lift-and-slide sash, the magnetic force of which counteracts the weight of the lift-and-slide sash.
• the at least one magnetic arrangement comprises at least one electromagnet, and a ferromagnetic element is associated with the magnetic arrangement. This element is attracted when the at least one lift-and-slide sash is lifted.
• the at least one electromagnet is arranged on a yoke that is U-shaped and whose end faces face the ferromagnetic element.
• the invention further relates to a method for lifting, lowering, and/or laterally guiding a lift-and-slide sash of a sliding door.
• Sliding doors with one or more lift-and-slide panels are known, which can be raised or lowered manually. In the raised position, they are usually mounted on rollers so that they can be moved horizontally. In the lowered position, the rollers are generally retracted, so that the lift-and-slide panel(s) rest on the surface and are already secured against further movement by sliding friction. Additional locking elements, such as interlocking mechanisms, may also be provided.
• this type of roller guide has proven effective. However, particularly as the running surfaces and/or rollers become increasingly dirty over time, a disturbing noise can develop. Furthermore, dirt makes movement more difficult due to increased friction.
• a sliding door is known that overcomes these disadvantages by bringing the door into a state of suspension through the repulsive force of permanent magnets. Lateral guidance is provided only by rollers and/or sliding elements. Permanent magnets are arranged in both the frame and the sliding sash and are oriented so that they repel each other. Since the magnetic force is strongly dependent on distance, an equilibrium is reached in the repulsive arrangement at a distance between the oppositely polarized magnets where the distance-dependent magnetic force exactly matches the force of gravity on the sash.
• a disadvantage of this method is that the door remains permanently in the raised position, meaning that lateral movement is not prevented or hindered by gravity and static or kinetic friction.
• Another disadvantage is that the magnetic force of permanent magnets diminishes over time, which can lead to the door catching when sliding, causing it to drag and eventually become unusable. To counteract this, magnets can be used whose initial magnetic force far exceeds the force required to lift the door leaf, but this incurs additional costs.
• the printed matter US 2015/0345198 A1 The image also shows a sliding door that is lifted by magnetic forces. Attractive or repulsive magnetic forces from permanent magnets or electromagnets can be used.
• a sliding door which has an upper sash frame element with two electromagnets arranged on a U-shaped yoke, the end faces of which face a ferromagnetic guide rail.
• the guide rail is mounted on the ceiling side, so that when the electromagnets are energized, the yoke and thus the sash are lifted.
• At least one electromagnet is arranged on a yoke that is U-shaped and whose end faces face the ferromagnetic element.
• the yoke directs the magnetic field lines as much as possible.
• the enclosed design effectively achieves a high magnetic force.
• the yoke also allows for a space-saving arrangement of at least one electromagnet.
• an electromagnet's attractive magnetic force is used, for example, realized by a coil.
• the lifting/sliding sash is raised by this attractive magnetic force through the interaction of the electromagnet with at least one ferromagnetic element, which can also form a yoke.
• This at least one magnet arrangement can be located in the lower and/or upper area of the sliding door.
• repulsive magnetic force is used for lifting, as this creates a system that is stable with respect to the established distance.
• an equilibrium distance is automatically established because the magnetic force and gravity balance each other in opposite directions and of the same absolute magnitude. If, however, the distance between different magnetic poles decreases during lifting, a system that is not self-adjusting with respect to the distance is created, in which the attractive force increases as the pole distance decreases.
• the magnetic forces in the sliding door according to the invention can be varied using the electromagnet, a desired distance can still be set, even if the system does not have a stable equilibrium distance.
• the at least one magnetic arrangement of the sliding door additionally comprises at least one permanent magnet, which is arranged together with the at least one electromagnet in a magnetic circuit.
• the at least one permanent magnet is arranged together with the electromagnet on the yoke or integrated into the yoke.
• the permanent magnet's magnetic force assists the electromagnet, allowing the latter to be smaller and/or operated with lower currents. Different currents applied to the electromagnet also make it possible in this combined system to vary the overall magnetic force and thus to control the raising, lowering, or holding of the sliding door panel.
• the at least one electromagnet can be energized in such a way that its magnetic force assists that of the permanent magnet (particularly when raising the sliding door panel), or in such a way that it counteracts the effect of the permanent magnet. This counteracts (e.g., when lowering the lift/slide sash). Furthermore, the electromagnet can be advantageously used to compensate for, for example, a decrease in the permanent magnet force due to age or temperature.
• the yoke is mechanically connected to the lift/slide sash and positioned under a base plate in a lower guide rail of the frame, the base plate forming the ferromagnetic element.
• the at least one magnet arrangement is positioned in the lower guide rail in a space-saving manner and lifts the lift/slide sash at its underside.

• the at least one magnetic arrangement includes at least one position sensor that measures the height position of the lift/slide sash relative to the frame.
• a control system is preferably provided that is configured to evaluate the measured values of the at least one position sensor and to control the electromagnet so that a predetermined height position of the lift/slide sash is assumed or maintained.
• the lower guide rail comprises a lower guide profile in which a chamber is formed in the longitudinal direction, in which the yoke with the at least one permanent magnet and the at least one electromagnet is received.
• At least one plunger is arranged centrally on the yoke, projecting through a slot in the base plate and attached to a lower frame profile of the at least one lifting/sliding sash.
• the mechanical connection between the magnet assembly and the lower frame profile is made via the plunger(s).
• a coil is wound onto the yoke on each side of the at least one plunger as an electromagnet. To lift the lifting/sliding sash, both coils are energized essentially uniformly in a current direction that increases the permanent flux generated by the at least one permanent magnet.
• the magnet assembly then pulls itself upwards towards the base plate, this movement being controlled by a The force is transferred to the centrally located stamp on the lifting/sliding sash, which is then also lifted.
• the armature In the resting state of the sliding door panel, the armature is attracted to one of the ferromagnetic side plates, resulting in a stable rest position in which the armature is firmly pressed against this ferromagnetic side plate. Due to this frictional engagement, sliding movement of the sliding door panel is at least hindered.
• the electromagnet When the electromagnet is energized, the armature leaves its rest position and can be moved into a central position between the two ferromagnetic side plates, in which the lifting/sliding wing can be moved with as little friction as possible after being lifted.

• a position sensor (not shown) is also provided here, which detects a lateral position of the armature 161 between the ferromagnetic side plates 17 or relative to a wall of the upper guide profile 18, and whose measured values are used in a control loop to control the coil 163 in order to adjust the position of the armature 161.
• Fig. 7b to maintain the lateral position shown, even if disturbances act on the lifting/sliding sash 3.
