Abstract:
In the roof window, each hinge (110) of the set of hinges comprises a frame hinge part (130), a sash hinge part (140), and a movement supporting assembly comprising guiding means including a linkage mechanism with at least two links (150, 160) providing connection between the sash hinge part and the frame hinge part. Each link is connected to at least one of the frame hinge part and the sash hinge part at a joint and connected to each other. The hinge (110) furthermore comprises a braking device (180) acting on at least one element of the movement supporting assembly over at least a part of the opening and/or closing movement. The braking device (180) comprises one or more friction elements.
Abstract:
A sliding power lift and locking assembly for lifting and locking an object includes a motor, a first drive shaft, a first drive block assembly, a first drive housing, and a link arm. The first drive shaft has a body and a cylindrical axis and is rotationally driven by the motor. The first drive block assembly includes an aperture configured to engage the body of the first drive shaft, a latch dog with a first slot configured to engage a dog catch pin associated with the object, and a slider. A portion of the first drive housing and a portion of the first drive block assembly are provided in a track of the first drive housing, and the track of the first drive housing is configured such that the first drive block assembly is configured to move in a path relative to the first drive housing. The link arm includes a first end and second end. The first end of the link arm is configured to move with the slider of the first drive block assembly, and the second end of the link arm is configured to connect to the object.
Abstract:
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.
Abstract:
A rain sensor arrangement for an operator for a window having a frame, a sash pivotable with respect to the frame, and a pane mounted in the sash, wherein the operator is adapted for pivoting the sash between a closed and an open position and vice versa, and is controlled via control circuitry responsive to input signals from at least a rain sensor. The rain sensor has at least one sensing area arranged so as to be protected against rain by the window, when the sash is in the closed position.
Abstract:
The present invention relates to roof vents and particularly roof vents which can be slid relative to the roof on which they are mounted. The roof vent has a simple mechanism, and is sealable to prevent the ingress of water through the roof vent.
Abstract:
The window frame structure of the roof window is secured to the main frame structure within a predetermined range of the opening angle by means of a securing device comprising at least one torsion member. The torsion member is torsionally biased in the opening direction of the window and includes engagement means at a distance from the pivot axis for engagement with corresponding engagement means on the window frame structure. The securing device is automatically activated and deactivated during mounting and dismounting of the window frame from the main frame.

Abstract:
A panel assembly comprises first and second bi-parting panel groups. Each group has at least a first and a second panel movable between a retracted and an extended position for opening and closing the panel assembly. The second panel in each group travels farther than and across the first panel in each group when the panels move between their retracted and extended positions.
Abstract:
In a window with a frame of extruded profile members the exterior side of an edge portion of a thermo pane is supported by a first flange portion of the profile member and the inside by a glazing bead connected with the frame profile member. The main frame mainly consists of wood profiles, the exterior sides of which are covered by weather-resisting coverings. A hinge member at the top of the window comprises an edge portion (28) of an extruded profile member (27) forming a hinge pivot firmly connected to the main frame portion (20) at this side and a hook-shaped wall portion (6) of the opposite frame profile member (1) forming a hinge blade. At one of the other sides of the window an arrangement is provided to ensure engagement of said hinge pivot and hinge blade forming portions in the closed position of the window. Such arrangements may comprise a sliding block (31) arranged displaceably in a track in the frame profile member, which block can be moved between a position opposite a retaining device anchored in the main frame structure for permanently securing the frame in case of a fixed window and a position in which it can be connected to a motion transfer member which is guided in a recess in the wood profile of the main frame for complete accommodation of the motion transfer member in the closed position of an openable window.
Abstract:
In an electric drive arrangement for a cord winding and dewinding winch (22), in particular for cord-operated screening and opening/closing devices for windows and doors, in which the operating cord (4) is connected with said device for moving it in one direction when winding up the cord on said winch (22), the latter being turned in one direction by means of an electric motor (12), while movement in the other direction is effected by a spring force acting on the device while dewinding the cord from the winch (22), the latter being turned by the electric motor (12) in the opposite direction, the winding and dewinding winch (22) for the cord is combined into a drive unit with the electric motor (12) and connected thereto by a transmission device, which is influenced by a braking force, means being provided for stopping the electric motor in response to suspension of the tension in the cord (4) caused by the movement in said other direction effected by the spring force, when dewinding the cord, said stopping means including a detector (18,19) influenced by the rotation of the winch (22).
