Abstract: The carriage provided to hold a displaceable separation element comprises a carriage body provided with at least two running wheels, which carriage body is connected to a carrier profile, which serves to carry the separation element. According to the invention the threaded shank of an adjusting screw is rotationally held in the carriage body, which adjusting screw comprises below the screw head a flange ring, which supports a flange element provided in the carrier profile, which flange element comprises an opening, through which the screw head is guided. By rotating the adjusting screw the carrier profile can thus be optionally adjusted in height. In a preferred embodiment a tool channel is provided in the carrier profile, into which tool channel a conventional tool can be introduced.

Abstract: The invention relates to a device for supporting a displaceable separation element (3), in particular a sliding door. Said device comprises a carriage (1), which is guided in a rail (2), equipped with a carriage body (10) and mechanically mounted in the rail (2) by means of rollers (8) or at least one sliding element (11; 110). The rail comprises a central part (2?) and two lateral parts (2?), which are equipped with opposing rail feet (21) that mechanically support the carriage (1). According to the invention, the carriage body (10) is provided with at least one hard magnetic magnet (12, 120), which exerts a force on at least one of the rail magnets (22, 22?, 22?, 220, 2200) that is connected to the rail (2), said force acting in opposition, preferably in an axially parallel manner, to the gravitational force exerted by the separation element (3) on the carriage (1).

Abstract: The invention relates to a device for operating an optionally rotatable and parkable divider element which may be displaced in a linear and/or curved manner, fixed to at least two running gears, provided with support rollers which run in a running track, of which at least the first running gear is provided with a drive shaft arranged in a direction perpendicular to the running direction thereof, by means of which a drive wheel may be rotated which engages in a toothed element arranged along an inner wall of the running track. According to the invention, the first running gear is provided with an electric motor, arranged between the support rollers, the motor shaft of which is fixed to the drive shaft.
