Explosion-protected glazing has swing window casement with hooked projection engaging in groove in window frame to ensure window remains closed against pressure waves

摘要

The glazing has a swing window casement with window pane and a groove formed between an external base profiled region of the frame window frame (30) and an internal hooked projection (32.1). The casement window has a hooked projection (12.1) which engages in the groove at least in part when the window is closed. In the event of explosion and pressure waves the window remains tightly closed. The hooked projections preferably run perpendicular to the plane of the window frame or casement.
