Abstract: In a window comprising a main frame (1), an intermediate frame (3) hinged at the top of the latter and a sash (7) which is journalled as a pivot sash in the intermediate frame, said intermediate frame (3) is provided with an arresting means (5) in the area of the pivoting axis (2), said arresting means normally being engaged with an associate arresting means (6) in the main frame. The arrest can be disengaged by means of a release handle (9) which is placed on the inner side of the main frame (1), and the window can then serve as an emergency exit, as the intermediate frame (3) with the sash (7) is swung clear of the main frame due to a permanent urging of the intermediate frame in its opening direction.

Abstract: The novel arrangement relates to a skylight with a case and a wing mounted thereon for pivoting about a horizontal axis and swinging about a further horizontal axis, the swinging axis being partially constituted by axial pins at the sides of the wing which are displaceable while supported on the case, with a cover partially overlapping the wing and case, the cover being pivotally linked at one end to the case and at the other end at the wing, the axial pins being arranged between the linkages and the wing having a guard for covering the case at least in the range not overlapped by the cover, with at least one weight balancing device arranged on one of the longitudinal struts of the wing whose two-armed support lever pivotal about a bearing pin consists of a support arm carrying a roller and a tension arm to which a tension spring is linked which is adjustable by means of a tensioning device affixed to the wing.

Abstract: In skylights wherein the wing may be selectively adjusted into a pivoting and swivel position, the wing is fixed with respect to the auxiliary frame in the pivoted opened position. If this fixation is removed due to a faulty operation, the upper, heavier half of the wing moves in the direction of the case so that there is a danger of damage. To make the negative effects of the faulty operation ineffective, flap 18 provided with latch 19 and having a pivoting axis displaced in relation to axial pin 7 in the direction of swivel joint 5 is pivotally mounted on auxiliary frame 2. Latch 19 arranged at a slight distance from axial pin 7 in the closed position subtends axial pin 7 when wing 3 is pivoted open. In case of a faulty operation, the weight of wing 3 causes axial pin 7 to be pressed against latch 19 of flap 18. This automatically secures a pivotally opened skylight against the results of a faulty operation, which is automatically undone, FIG. 4, when the wing is brought into the closed position.

Abstract: In a tilting window having a main frame (1), an intermediate frame (3) top-hinged therein, and a sash (7) pivotally mounted or tilting movement in the intermediate frame, said sash (7) comprises an arresting member (10) which is located in the vicinity of the pivot bearing (6) of the sash and upon closing of the window, which is effected by coordinated tilting of the sash in relation to the intermediate frame and swinging of said intermediate frame in relation to the main frame, engages an associate arresting member (11) on the main frame. After locking together the intermediate frame (3) and the sash (7) at the top, the window will be firmly held in a closed or in a slightly open position. The operation of the window requires only a locking or coupling mechanism at the top of the window.

Abstract: A window with a sash mounted in a frame has elongated draft stops extending along the rails of the sash. The draft stops are disposed in the frame and normally project out to overlap the sash rails. The draft stops are retractible outwardly beyond the outer edges of the rails and the sash is mounted to turn about its vertical centerline when the draft stops are retracted. When a handle mounted in the frame is turned in one direction, it operates a mechanism to retract the lower draft stop. The side draft stops retract in response to retraction of the lower draft stop and this, in turn, raises the upper draft stop so that all of the draft stops are retracted together. Turning the handle in the opposite direction returns all of the draft stops to their projected or active position.
