Device for opening and closing curtains as well as a method for connecting an electric motor drive and/or a deflection to the profile cross-section of a curtain rail

Abstract

A device for opening and closing curtains includes a curtain rail with at least one channel open in the curtain-to-be-hung direction and at least one curtain holding part held movably in the channel in the channel longitudinal direction by guides, for attaching the curtain. The guides are adjustable along the rail via an electric motor drive by a drive mechanism. A laterally-arranged, window-like opening is made in at least one section of the rail profile cross-section, which provides access from outside the rail at least to the channel for the drive mechanism. A structural unit for the electromotive drive and/or a deflection of the drive mechanism is insertable into this opening and fixable therein laterally on the rail for passing the drive mechanism through the region for the electromotive drive and/or the deflection. Also, a method connects an electromotive drive and/or a deflection to the rail profile cross-section.
