The terrace glasswork, which is particularly simple to adapt to building conditions, contains the following features: (a) It is made up of a vaulted roof, which is supported above on an existing wall and below on the terrace floor; as well as two gable parts. (b) The roof is made up along its length of several identical, glassed in arch components, the side frame parts of which can be joined and sealed to one another. Each of the latter has two movable glass panes (17, 20) guided so as to slide at different levels. (c) The gable parts are each made up of three gable components, namely of a square basic component (4) and two connecting components (5a, 6a) each of which to the arch components, and which connects together two right-angled frame sides of the basic component (4).

This invention relates to a locking device for a raisable or liftable venetian blind in which the bottom rail of the venetian blind includes an end piece extending into and guided by the side housing of the blind and in which a flexible lifting member engages the end piece of the bottom rail to raise and lower the same. A spring urged pivoted latch is provided within the lower portion of the housing which automatically engages over the end piece of the bottom rail when it is in the lowered position and the tension in the lifting member is relaxed. Thus the blind is locked in the down position. When tension is applied to the lifting member to lift the blind, the lifting member moves the latch out of locking engagement with the end piece permitting the blind to be raised.

An automatic protection device for a roller blind to prevent unauthorized raising of the blind from the outside by means of two-arm toggle joints whose lever ends are linked at one of the adjacent roller blind staves so that upon unauthorized raising the free toggle joint moves against the flange of U-shaped guide channel in combination with a compensating member in the face region of the upper roller blind stave and movable relative thereto exerts on the locking teeth of the free toggle joint through the action of an additional force means such as an elastic compressible material, a pressure by which the locking teeth are brought against the flange of the guide channel. This not only assures positive locking but also acts to compensate for differences in stave spacings and widths of guide channels thereby reducing manufacturing and inventory costs.
