Abstract: The invention relates to a system for covering a surface portion of a building. It includes a covering for covering a building surface portion, and a support frame for attachment to a surface of a building. The covering has a slidable frame with a carriage adapted for longitudinal movement along a guide track. The support frame has a guide track member provided with a guide track for accommodating the carriage. The support frame has a member for sealing an interface between the support frame and the covering frame when the covering is positioned in a position in front of the support frame. The sealing member is a strip seal having an attachment part and a sealing part, including folding lines that extend in the longitudinal direction of the strip seal. The space between the covering and the surface portion to be covered is sealed against humidity and temperature differences.

Abstract: The invention relates to a mechanism for converting a rotary motion originating from a rotary energy generator (1) into a longitudinal motion of a carriage (25) that is adapted for attachment to a covering, such that said rotary motion will result in a longitudinal displacement of the covering, the mechanism comprising one or more spindle sections (2, 3, 4, 5) drivingly connected at a longitudinal end of at least one of said spindle sections via a gear means (7; 9; 22, 23, 24, 27) to said rotary energy generator (1). The invention further relates to a drive system for coverings comprising mechanisms according to the invention. The invention further relates to a covering system for covering a surface portion such as a window, glass door or the like, of a building.

Abstract: The present invention relates to a very flexible Venetian blind that easily can be adapted to various sizes of for instance window openings, by a person having limited skill in mounting and adapting Venetian blinds. Also the Venetian blind according to the invention is designed such that individual slats can easily be removed for instance to change the overall size of the Venetian blind or for repair or replacement of individual slats. It is hence also easy according to the invention to change the overall appearance, for instance colour, of the Venetian blinds to meet changing requirements. These and other objects and advantages are attained by the Venetian blind according to the invention. It is understood that although the various elements of the Venetian blind according to the invention here are described and shown as used to form one specific Venetian blind it is also possible to use one or more of the elements (for instance the bottom portions, the lift mechanism etc.
