摘要： The invention concerns a window specially designed for emergency use. The window comprises a fixed outer frame (1) and a sash (2) mounted for normal horizontal pivoting movement between open and closed positions about axis Y-Y. Two arms (3) extend in the respective side rebates between the frame (1) and sash (2), and opposed horizontal pivots (6) are secured to the sash (2) and the arms (3) for such normal pivoting movement of the sash (2). Each arm (3) is connected to the top (1 a ) of the frame (1) by a hinge (4) and each arm is acted on by a respective telescopic gas spring (5) confined within the rebate but acting on the associated arm (3) to urge it outwardly of the frame (1). For normal opening and closing movement of the sash (2) for which a casement fastener (7) is fitted, the arms (3) are retained secured to the frame (1) by a catch arrangement that is operable manually by a control handle (8) separate to the fastener (7). For emergency opening of the window, the control handle (8) is actuated and the catch means is released to disengage the lower ends of the arms (3) so that the forces applied by the gas springs (5) act on the arms (3) causing the arms to move outwardly of the frame (1) about the hinge axis Z-Z carrying the sash (2) outwardly clear of the opening of the frame (1) for emergency access. Special features for automatic re-engagement of the catch means and control of the system are described in detail. The invention has particular application for roof windows.
