Casement window frame esp. for French windows

摘要

The window consists of a panel (2) which opens outwards relative to a fixed surround (2), both made from identical metal extrusions (4, 15). The opening panel is locked in the closed position by a handle (11) mounted on the fixed surround and actuating a box (13) with long bolts. Each of the extrusions has a zone on which a handle can be fitted and another for a seal (23). The opening panel also has a hook (24) to open and close it by.
