Abstract: A connecting assembly for installing the sash of a house skylight to the sides of its casement, has connecting parts that can pivot relative to each other, and the casement has holding elements that have cross sections which will engage therewith. This assembly allows the window sash to be inserted from the interior rapidly and in a simple manner by engagement with the positioning arms on the casement. This is achieved by the connecting parts (3) having a U-shaped cross section (4), which accept swinging positioning arms (5) which serve as the holding elements, and these connections can be locked by self-engaging attachment elements (6) that can be engaged without tools.

Abstract: The invention concerns a hinged, swinging skylight in which the sash can rotate and is carried by two arms arranged so they can swivel on the upper end of the casement. The sash is held in the swinging position by spindles that seat in grooves or channels on the side members of the casement and can move therein. In the hinged position, the sash is tightly connected to the arms. To increase comfort and improve operability, the grooves have no limits for the upper ends and the spindles are able to move longitudinally along the side rails of the sash by activating a handle in such a way that they are in the grooves in the swinging position and outside the grooves in the hinged position. At the same time, coupling elements are activated by the handle and are connected tightly to the arms in the hinged position of the sash, and this connection is released in the swinging position.

Abstract: A skylight has a sash, a casement and [spring-loaded.revreaction. carrier arms which are mounted at one end to the casement and at the other end on a pivot bearing on the sash side rail. The sash has spindles cooperating with a U-shaped runner on the side member of the casement. A cover plate borders the channel of the runner and overlaps the spindles when the sash is in the swinging position. When the sash is in the closed position [and the swinging position], the spindles is outside the working range of the cover plate. When the sash is opened and the carrier arm is coupled thereto, it tilts on the pivot bearing. When opened with the sash uncoupled from the carrier arms, the spindle move in the grooves of the runner toward the lower edge of the casement, and the pivot bearing on the casement is lifted off and the sash swings open. The spindles are positioned on the side rail of the sash and move longitudinally when they are seated in individual settings by movement of the handle on the sash cross member.

The window includes an insulating glass pane made of a colorless glass pane and a selective absorption pane, a frame enclosing the insulating glass pane on all sides, a hinge arranged in the area of one lateral edge for the opening of the casement, a reversing hinge arranged in a vertical or horizontal central axis on the frame for the 180.degree. rotation of the insulating glass pane, a structurally fixed blind frame and an encircling gasket between the structurally fixed blind frame and the frame for the insulating glass pane.

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: Between regions of different air pressure, a door pivots on an axis located a substantial distance from the nearest edge; this edge moves inwardly as the door pivots about the door axis in a first phase of opening movement to relieve the difference in pressure on opposite sides of the door; pivot links then carry the door about a second axis, parallel to the first axis, in a second phase movement which moves the entire door outwardly to the open position.

Abstract: A window of a residential roof with a window wing (a folding skylight shutter) which is supportably relieved of weight by an accumulator and which swings open about an upper axis of the blind window frame, the wing after decoupling additionally being able to be turned over about an axis lying substantially in the longitudinal center line, the axial pins of the last-mentioned axis being seated on carrier arms which are articulated in the vicinity of the upper transverse leg of the blind window frame and extend in the direction of the longitudinal legs of the blind window frame.

Abstract: A roof window whose installed frame has upper and lower horizontal members and obliquely sloping side members has a casement attached to the upper frame member by two links fastened by fixed pivot pins to the respective center portions of the side rails of the casement and to the two ends of the upper frame member. Slides on the side rails slide along the side members of the frame when the links pivot on the upper frame member while the casement pivots on the links. The casement may be locked to the links for joint movement about the pivot pins on the upper frame member toward and away from the closing position of the casement in which the casement closes the opening bounded by the members of the frame. The slides abuttingly engage the side members of the frame in the closing position of the casement and move away from the frame members when the casement swings jointly with the links away from the closing position.

Abstract: A ventilator is positioned in the opening in a motor vehicle roof so that it can be moved between a closed position sealing the opening and a number of different oblique opening positions. Levers attached to the roof and connected to a shaft pivotally mounted on the cover affect the pivotal movement of the cover at its rear end. A mechanism is provided to selectively disconnect those levers from the roof to enable the ventilator to be fully removed, with the links attached to the ventilator.

Abstract: A silo door structure having a ladder rung assembly on which the door is supported, the rung assembly including vertical pivot pin extensions received within vertical apertures formed in the top and bottom cross beams of the door frame.
