Abstract: A roller rail for a sliding wall, which includes several sliding wall elements, in which each sliding wall element is supported to be displaceable via in particular two carriages. The roller rail is connectable to a branching roller rail via a turnout which is switchable by the carriages. At least one carriage of a sliding wall element, for switching the turnout, takes up a position which is located outside the turnout.

Abstract: A linear motor arrangement for panels, in particular sliding door leaves, movable along a travel path, as well as to a device for mounting such an arrangement includes a linear drive system having at least one stator member of a linear motor and a connecting member as components. The connecting member comprises a circuitry. The components are consecutively disposed in a row. Furthermore, the connecting member has a housing, which, at one end, has at least one connection possibility for an external energy supply. In addition, the housing, respectively the connecting member is adapted, to receive circuitry, which has additional terminals. In order to be able to run connecting lines in the connecting member, a channel is configured in the housing such that they are led out of the housing at the end of the connection possibility.

Abstract: The invention relates to an electrical or electromechanical hold-open device, particularly for doors, which is displaceable within a sliding rail, the sliding rail comprising a lower chamber and an upper chamber, a power supply unit being disposed in the upper chamber and a slide member with a holding mechanism and a retaining mechanism being disposed in the lower chamber. This measure is intended to provide an electrical or electromechanical hold-open device which, compared to prior art hold-open devices, is improved particularly with regard to the power supply.
