A hinge for pivot roof windows, according to the present invention, comprises two hinge parts, one hinge part (A) secured to a window frame, and the other hinge part (B) secured to the side member of a sash frame. Each hinge part has a base plate (1A, 1B) fitted with securing means (2) and with means (4, 6) for performing pivoting of the base plates (1A, 1B) relative to each other, at the same time a hinge is equipped with at least one fastening unit comprising an arm (9), being an extension of the base plate and a slidable fastener (11) with a hole (13) perpendicular to the fastener slide direction secured to the arm (9) and a securing member (14) secured in parallel to the fastener slide direction. If a hinge has only one fastening unit (9, 10), which constitutes a part of one base plate (1A, 1B), the other base plate is equipped with the known fixed fastener.

The pantographs (3a) at their free end are interconnected by a bar (7a), which together with the sill element (9) forms such a kinematic system that turning round the bar (7) pulled at its crank forces the catching element (7a) to turn and to move in relation of the sill element (9), releasing by this the ladder (3) from its lock and enabling to expand the ladder (3). The sill element (9) has in its cross-section parallel to side element of the ladder (3) a triangular profile and has an abutting surface on the side of the hinges connecting the flap (2) with the hatch frame (1), which surface passes arch wise into an adjoining sliding surface forming an acute angle with the surface of the flap (2).
摘要:
A pivot hinge for roof windows with a sash pivoting around the axis located between the upper and the lower member of a window, has a balancing system, which ensures the state of equilibrium of a window sash when its centre of gravity is located outside the sash rotating axis and the friction spring of the hinge is unable to hold the sash pivoted in each its position. At the same time the window fittings, its assembly, installation in a roof and its appearance remain unchanged. Also the method of separating of both hinge parts (taking a sash out of a window frame) remains unchanged.

A handle specific by the mechanical subassembly keeping the locking slug (7) in releasing or blocking position, which is totally contained in the handle lever (20. The mechanical subassembly keeping the locking slug (7) in releasing position consists of a flat rotary disk (5) with a tongue (12) set in the body (2) and rigidly connected with the stem (1 a), which is a part of the lever (1).

An awning consisting of an assembly rail (1) and a body connected together in hinged mode about a turning axis parallel to the axle (7) of the roller (8), the assembly rail being fixed to the external surface of the window cover and the body able to be turned aside when mounting the assembly rail. The assembly rail (1) and the housing (2) are connected together by an elastic hinge joint (3).

The stairs have a safety device ( 3 ) for protection against uncontrolled detachment of at least two last segments from the first segment ( 11 ) by rotation on the hinges ( 21 ), which mechanism is positioned near the top ends of the segments, beneficially overlaid on the extension hinge ( 23 ) that joins together segments 2 ( 12 ) and 3 ( 13 ). The safety device ( 3 ) is unlatched by the user lifting the bottom parts of segments 3 ( 13 ) and 4 ( 14 ). Also, the stairs have a bottom lock ( 6 ) installed on the hinge ( 22 ) that joins together segments 3 ( 13 ) and 4 ( 14 ).
摘要:
Flashing system, for sealing the joint of a set of at least two roof penetrating structures placed directly next to each other in the roof slope, comprising extreme members: bottom member (1), top member (2), side members (3), and an intermediary member in the form of a trough (4) for draining water, located between the adjacent side edges of the roof penetrating structures, with side arms covered by the sheeting of the adjacent roof penetrating structures, characterised in that the top members (2) are secured to the common trough (4) with fasteners made of a plastically deformable material, permanently connected to the trough (4).
