Abstract: A front-end section for a motor vehicle, having at least one air inlet opening for supplying a cooling air volume flow to a cooling module arranged behind the air inlet opening. In the air inlet opening, there is arranged in each case one slat device with multiple adjustable slats which are arranged adjacent to one another and which are each pivotable about a pivot axis between a closed slat position and an open slat position. The slats each have, at their end facing toward the cooling module, an air-guiding element which is configured such that, in an at least partially open slat position, the cooling air volume flow is diverted in the direction of the cooling module by the air-guiding element.

Abstract: The invention relates to a refinement of a spindle drive (1), and to a louvered window or a louvered shutter having a spindle drive for moving louver elements such that applied return forces and return torques can be absorbed better, and in particular without placing a load on the drive motor. For this purpose, the spindle drive (1) has a specially designed return stop mechanism (6) arranged between a drive shaft of a drive motor (3) and a threaded spindle (4).

Abstract: A device for opening and closing a pivoting wing, comprising: a stationary support intended to be attached to a fixed frame, a slide movable relative to the stationary support along a rectilinear direction between an open wing position and a closed and locked wing position, a pivoting arm articulated to the stationary support about an articulation axis, and having a distal end intended to be connected to the wing, a transmission mechanism associated with the slide and the arm, comprising an essentially L-shaped cam engaged by a control pin, the transmission mechanism being configured to transform the rectilinear movement of the slide along said rectilinear direction into a pivoting movement of the arm about said pivot axis.

Abstract: An opening and closing device includes a base plate rotatably supported by a stand to rotate between closed and open positions, a sliding plate slidably provided on the base plate to slide between first and second positions, an urging part to urge the sliding plate toward the second position, where the sliding plate projects from the base plate, a movement restriction mechanism including first and second members provided on one and the other, respectively, of the stand and the sliding plate, and configured to restrict the movements of the base plate and the sliding plate by the engagement of the first and second members when the base plate is at the closed position, and a moving and urging mechanism to move and urge the sliding plate toward the first position from the second position with the movement of the base plate from the open position to the closed position.

Abstract: An adjustable window awning/light shelf includes a canopy attached to supports on both sides of the window. The supports are engaged with vertical drive screws providing for the possibility of moving the canopy up and down. Each drive screw is connected with a common drive shaft. During the cooling season, the canopy is disposed at the top of the window, shading the window from the sun. During the heating season, the canopy is brought down to the bottom of the window by rotating the drive shaft, which in turn rotates the drive screws and moves the supports with the canopy down. Canopy's angle relative to the window increases. When in the bottom position, the awning performs as a light shelf, reflecting sunlight into the window and increasing the amount of sunlight and solar heat entering the building through the window.

Abstract: A pivoting shutter having adjustable slats for buildings includes an upper panel provided with a first group of adjustable slats, mounted by the upper end thereof on a horizontal pivoting shaft. A lower panel is provided with a second group of adjustable slats, hinged by the upper end thereof to the upper panel and connected by the lower end thereof to a driving means for vertical movement for pivoting the panels between an open position and a closed position. First and second connectors are provided, which, when rotating the slats, link the adjustable slats of the first and second groups, respectively. A transmission mechanism links the two groups of slats in the closed position of the upper and lower panels, enabling in the closed position the simultaneous rotation of all the slats, and maintaining the groups of slats unlinked from one another in the open position of the panels.

Abstract: A panelless shutter is provided, the panelless shutter including a window frame and a plurality of louvers horizontally mounted within the window frame in a parallel configuration, each louver having a first end and a second end. The panelless shutter also includes a louver mechanism comprising a plurality of rotatable members slideably retained within a track and a gear shaft operably coupled to each rotatable member, wherein the rotatable members are coupled to the first end of each louver of the plurality of louvers and the gear shaft rotates each of the plurality of louvers substantially simultaneously. The shutter further includes a louver retainer rotatably securing the second end of each louver of the plurality of louvers, the louver retainer allowing the rotation and vertical sliding of each louver.
