Abstract:
A hinge device for use in pivot windows consists of two hinge parts (1 and 10) adapted to be secured to the frame and the sash, respectively; one of the hinge parts having a part circular guide channel (6) for a likewise curved slide member (7) which through a hinge pin (13) supports the base plate (11) of the other hinge part. This base plate carries a guide pin (18) which by abutment against the concave side wall (5) of the guide channel prevents turning of the said base plate on the hinge pin (13), until the slide member has been displaced to the maximum in the opening direction, which guide pin during the displacement by abutment against a nose (20) on the end of the slide member (7) urges this member against the convex side wall (4) of the guide channel with the purpose of obtaining a friction adjusted to preventing an undesired displacement of the slide member.
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 openable window sash is in the closed position secured to the frame by locking means on the sash engaging lock fittings on the frame. After release of the locking means from the lock fittings my means of an operating device the sash is moved to an open position by at least one window operator (14, 15) positioned at a frame member. The sash is moved to a ventilating position by the operating device which has a motor (3) which via a driving member (4) moves a locking rod (7) which is longitudinally displaceable in a sash member (2), said locking rod being also in engagement with a relative to the longitudinal frame member inclined section (10) of a track (9) in the lock fitting (8) of the frame. By longitudinal displacement of the locking rod the sash is moved in a direction away from the frame, the sash being, until the ventilating position has been reached, secured to the frame by the engagement between the locking rod and the track of the lock fitting.
Abstract:
The sash structure of the window is hingedly connected (13-15; 51-53) with the frame structure for pivoting about a horizontal axis. The top, bottom and side members (1, 2, 4, 5; 31, 32, 34, 35) of the frame and sash structures are made from wood profiles with exterior cladding members (16-18; 46, 48) of weather-protecting material, and the top, bottom and side members (1, 2; 31, 32) of the frame structure are constituted by profiles with substantially parallelogram-shaped cross section with exterior edge faces (6; 36) positioned in a common plane, with which the adjacent opposite side faces (7, 8; 37, 38) of the profile cross section form an angle of 95 to 140 DEG , and the exterior cladding members overlap, in the closed position of the window, the spaces between the sash and frame structure and the hinge connection between them. The window may either be a pivoting window, in which the exterior cladding members (17) above the hinge connection (13-15) are connected with the frame structure and below the hinge connection to the sash structure, or be top-hung, in which case the top, bottom and side members (34, 35) are likewise constituted by profiles with substantially parallelogram-shaped cross section.
Abstract:
A dual window screening device comprises a first screening element (1) with a breadth of flexible screening material, which in the end is rolled up on a roller tube (2) at one of a pair of sash members positioned opposite each other (4), whereas the opposite end is connected with an end rail profile (5). A second screening element (8) is in one end fastened to the opposite sash member (9) and in the opposite end connected with an end rail profile (10). The screening device may be designed for manual or electronic operation and comprises guiding and arresting means permitting mutually independent adjustment of the two screening elements (1, 8) in arbitrary positions. The guiding and arresting means comprise a common guide track (11) for the screening elements so that these are used in a common guiding plane.
Abstract:
A plastically deformable flashing material, in particular for roof flashing purposes in connection with roof windows and similar roof penetrating building structures, consists of a sheet-, web- or strip-shaped expanded-metal grid (1) covered on both sides by an elastomeric layer (2). The expanded-metal grid (1) is pretreated to substantially uniform extensibility in directions substantially orthogonal to each other corresponding to the longitudinal and cross direction of the sheet-, web- or strip-form. The elastomeric layers (2) are of thermoplastic material, and the sandwich material shaped by the expanded-metal grid (1) and the elastomeric layers (2) is corrugated in a continuous waveform parallel to one of said directions substantially orthogonal to each other.
Abstract:
A screening arrangement for a window with a main frame (1) and a glass-carrying frame (2) journalled in the main frame, which frame can be moved to a ventilating position, in which the frame plane forms an angle with the main frame plane, so that at least one wedge-shaped ventilation aperture is formed between the main frame and the frame, said screening arrangement comprising an air-permeable insect screen (6), which in a mounted position has three wall-like sections (7, 8, 9) for screening the wedge-shaped ventilation aperture, the insect screen being folded into a bellows surface having an outer and an inner end fold, the inner end fold (10a) being connected with the corresponding main frame member and the outer end fold (10b) being carried by a screen-carrying, separate frame (4) connected with the main frame by hinges for mounting on the outside of the glass-carrying frame (2). The screen-carrying frame is in a distance from its hinged connection (5) with the top member of the main frame displaceably connected with the glass-carrying frame. The screening arrangement may furthermore comprise a screening situated in the plane of the screen-carrying frame, which screening is preferably a roll-up screening.
Abstract:
An electrical rain sensor to be mounted on the outside of the main frame of an openable window, particularly a skylight, comprising a sensing element with two electrodes mounted opposite one another in an insulating holder, the distance between the electrodes being less than the size of a raindrop. To the electrodes an electric circuit is connected which by detection of a change in an electrical quantity caused by the presence of raindrops, activates a maneuvering device which closes the window. The holder (8) is produced by moulding of an electrically insulating thermoplastic, wherein the supply lines to the electrodes (15, 16) as well as a heating element for the drying of the sensor is produced as inserts in the holder by moulding of an electrically conductive thermoplastic polymer into excavated recesses and/or grooves in the holder (8). The electrodes can be designed as coatings of a weather resistant conducting material, particularly material containing graphite, the conducting material being applied to most of the surface of the sensor.
Abstract:
A flashing arrangement for windows including flashing elements (2-5) attached to the members of the window frame (1) for providing a waterproof flashing frame around the window frame. The flashing elements (2, 3, 4) at the top member and side members of the window frame are made of profiles of an elastically deformable material and have a U-shaped cross section, where the first side flange (8) is attached to the outside of the corresponding member of the window frame, while the other side flange (9) provides sealing abutment with the underside of the surrounding roofing. The flashing element at the bottom member comprises a mainly L-shaped profile with an upright flange for connection to the bottom member of the window frame and an outwardly protruding flange (11), which can be connected to a flexible and mainly strip-shaped flashing element (12) of a plastically deformable material. The flashing frame can be manufactured by welding together extruded profile elements made of rubber or a thermoplastic elastomer or in one piece by injection moulding.
