A vertical Venetian blind employs a plurality of slats adapted to be moved between an open position and a closed position. When the slats are in their closed position, pivotally mounted spacer bars maintain a predetermined center-to-center distance between adjacent slats. A rotatable drive shaft, which is employed to move the slats between their open and closed positions, can be supported along substantially its entire length by a bearing to thereby prevent the drive shaft from sagging.

Device for protection from the sun

Prismatic plates are float-mounted between glass panes of a composite window by means of a spacer which is attached to the inside of a bridge which connects the glass panes. This attachment comprises a dove-tailed groove and a prismatic component which fits into the groove. This connection allows the components to be displaced in the event of thermal expansion and also permits easy assembly.

Composite window

Since only relatively small-area prism sub-plates can be manufactured in warp-free fashion, large area prism plates are formed of a plurality of sub-plates. A connection of the sub-plates must be stable and the expense for joining the sub-plates should be as low as possible. To create the large-area prism plate, adjoining sub-plates are connected to one another in two dimensions by at least one positive lock plug-type connection comprising locking projections and locking projection receptacleswhich form plug-type connections secured by latching devices which do not allow a dislocation of the joined sub-plates in a third dimension.
