Abstract: In a method and a device for determining a reference position of a locking part moved by an electric motor, the locking part is moved in the direction of the closed state thereof, until the same reaches a stop position. At that location the meter reading of a position meter describing the stop position is detected and buffered. Subsequently a movement of the locking part is carried out in the direction of the opened state thereof. The locking part is then moved again in the direction of the closed state thereof, until it again reaches a stop position. At that location a meter reading describing the stop position is detected, and compared to the buffered meter reading. If both meter readings agree, the first stop position is determined as the reference position. The method and device can be utilized, for example, for power window lifts and sunroofs of motor vehicles.

Abstract: A tri-vent awning window for absorbing sunlight heat in warm weather that otherwise would flow uncontrolled therethrough and discharging the sunlight heat to the atmosphere while permitting relatively unobstructed vision therethrough and passing the sunlight heat in cold weather therethrough for thermal warming. The tri-vent awning window includes a frame, an inner pane, an outer pane, and a heat sink. The inner pane is replaceably mounted to the frame so as to form a first vent. The outer pane is pivotally mounted to the frame so as to form a second vent, and is spaced from the inner pane so as to form a space therebetween. The heat sink is removably mounted to the frame, in the space, and when removed, creates a passive solar application. The inner pane has an in-place position and the outer pane has an open position during which in the warm weather the sunlight heat hits the heat sink and passes therethrough and rises by convection.

Abstract: The panel system is meant for construction of a panel fillet or a major panel surface to be mounted in a pitched roof or in a facade, comprising a number of fixed panels (1) together with a number of openable panels (2), each panel comprising a frame structure composed of frame members (13, 22) bordering a panelling element (32) between them, each frame member (13, 22) comprising a profile element (30) and at least a core element (35). The profile elements (30) are designed as uniform standard parts, and in that at least some frame members of the frame structure are provided with means to vary the moment of inertia, where the means can comprise at least one element (47) which is received in said core element (35) and which extend over essentially the entire length of the frame member.

Abstract: The panels (1, 2) are along a frame member connected to one or more support elements (3) in an angle of inclination in relation to a subjacent securing plane by means of mounting and hinge fittings (4) which can be adjusted in dependence of said angle of inclination, the fittings also constituting the hinge fittings of the openable panels. Each fitting (4) comprises a securing part for connection with the support element (3), a hinge part for connection with the frame structure of the panel (1, 2) and an adjustment part connecting the securing part with the hinge part.

Abstract: Lifting roof or sliding-lifting roof for vehicles with a rigid cover which can be lifted and lowered or lifted, lowered and retracted to open and close a roof opening provided in a stationary roof panel. For at least partial covering of edge gaps formed between lateral edges of the cover and the roof panel when the cover is lifted, strip-shaped lateral shields project outward and downward from the cover at both sides of the cover. These lateral shields are formed of a compressible foam material.

Abstract: There is disclosed a window unit, comprising a frame, a sash mounted in the frame for movement between a closed position adjacent the frame to an open position in which a space is defined between the sash and the frame, a recess in the frame adjacent the sash, and screen means attached to the sash and dimensioned to fill the space when the sash is in the open position.

Abstract: A solar protection device includes slats of refractive material rotatable about a longitudinal axis, having an even, flat upper side and having on their lower side prisms arranged serially without gaps and running parallel to the longitudinal axis. In order to maintain the condition for retroreflection with variations of the sun's position, the angle of inclination to the horizontal of the slats must be readjusted from time to time, at least seasonably. For automatic adjustment thereof a light sensing arrangement of two light sensors arranged oppositely on both cathetal legs of one of the prisms whose hypotenuse is formed by the upper side of the rotatable slat. Control by a drive and associated electronics is undertaken and continued as long as solar rays impinge on one of the light sensors with intensity exceeding a predetermined illumination level.

Abstract: A lifting sliding roof for a vehicle having a cover that is inserted into a cover opening and that, starting from a closed position, while lifting its rear edge, is tiltable into a tilted position and in this position is moved over the fixed part of the roof toward the rear into an open position. When the cover is lifted but rests against a front edge of the roof opening, air can flow via lateral gap areas and a rear gap area between the cover and the roof into the passenger compartment, but when the cover is tilted and is pushed to the rear at least partially, a sealing frame is provided that closes off the lateral gap areas and the rear gap area so that in this cover position, the air reaches the passenger compartment only through the area of the roof opening that is located in front of the cover.

Abstract: A skylight assembly for installation in an opening in the pitched roof of a building, comprising a window hinged at one end with respect to the roof, and a rubbery flashing member for maintaining a water-tight seal between the window and roof. The flashing member includes a planar portion for attachment to the roof, beneath the shingles, in an area adjacent to the opening, a portion for attachment to each side of the window, and a gusset portion between each attachment portion and the planar portion. The gusset portion expands and contracts as the window is opened and closed, respectively. All the portions of the flashing member are integrally formed at one piece. The gussets may be accordian-folded and may taper toward the hinged end of the window. The attachment portions of the flashing may be sandwiched between the window pane and window frame to serve as a gasket between those parts of the window.

Abstract: A variable alignment window assembly for mounting in a window frame of an enclosure which assembly allows greater light transmission and directional air admission into the enclosure, and which, when opened, may be used to shield out unwanted wind, rain, sun or observation from the outside, may be fabricated from one or more window units, each of which units has two vertically upright window panels angularly sealingly joined together along a common vertical side to form an outwardly projecting window unit having a common apical vertical edge and two vertical sides and means for vertically pivotally mounting, said means connecting a point on said window unit adjacent one of said vertical sides to one side of the window frame such that the unit is pivotable between a closed position, in which the vertical sides of the window are in sealing contact with the sides of the window frame, and an open position in which the vertical side of the unit which is not pivotally mounted to the window frame is outwardly remote

Abstract: An openable vehicle roof structure to serve as a retractable sliding roof or an air vent has a roof opening in the horizontal portion; a downwardly recessed frame surrounding the opening on at least its front and side edges, as an integral part of the roof structure; a rigid panel matching the opening and serving as a closure member for it when aligned with the edges thereof; a pivot connection between the panel and the roof frame which permits the panel to be pivoted about a horizontal axis located near its front edge, the rear edge of the panel being thereby movable upwardly out of the roof opening; two rigid, generally flat shutter members arranged adjacent to the lateral edges of the panel to extend along at least a major portion of the panel length; a connecting mechanism for movably connecting the shutter members to the panel so that, when the rigid panel is in its open, upwardly pivoted position, they extend downwardly from its lateral edges, thereby substantially covering the gap between the panel and

Abstract: The conversion unit is a simple frame structure applied inwardly of a window opening, such as in a residential basement equipped with metal casement windows. It comprises a pair of like triangular end members or panels bridged across inner upright edges thereof by a light-transmitting portion in which a pair of ornamentally decorated sliding panels are mounted, as in a pair of overlapped grooves in a frame part of the panel portion. The unit is applied with outer vertical edges thereof in abutted engagement with a wall carrying the casement window and with upper margins of the generally triangular open frame structure in upwardly flush engaging abutment with the room ceiling just above the casement window zone. the sliding panels are chosen of a decorative plastic, semi-rigid sheet, preferably somewhat flexible in nature, and also by preference provision is made for a removal of the unit from the casement area for full access to the castment window from its interior.
