Abstract: The invention relates to a slat (1) or a slatted roof (20) or a slatted window, comprising a light-permeable sheet-like covering element (2) having a longitudinal extent and width (b), wherein the width (b) is less than the longitudinal extent, and having an axis of rotation (5) which runs along the longitudinal extent of the slat (1) in order to pivot the slat (1) between a closed position and an open position.

Abstract: Disclosed is an air flap device for a vehicle which includes left and right flap units which are formed of a combination of a plurality of opposite flaps rotatably installed at left and right sides, wherein the left and right flap units are obliquely installed facing each other in such a way that the opposite side ends thereof protrude forward; a link which interconnects the other side ends of the plurality of flaps of the outer sides of the left and right flap units; and a driving force transfer unit which is installed between the left and right flap units and interconnects a predetermined pair of opposite left and right flaps of the left and right flap units.

Abstract: A louvered roof assembly includes a support frame and several panels mounted between the support frame. The panels are pivotally coupled to the support frame for rotation about an axis. Each of the panels has a first end and a second end. A linear drive mechanism is coupled to each of the panels. The linear drive mechanism is mounted within at least one of the beams of the support frame and includes an actuator arm mounted to one of the support members.

Abstract: The invention relates to an armored ventilation grille for an opening, the grille including an outer side to be exposed to a projectile shot and an inner side to be applied to the opening, the grille including a plurality of parallel bars, the bars having a V-shaped cross-section, each limb of the V being made of of a blade, the blades being arranged in chevrons in order to form baffles such that at least one blade is located in the trajectory of the projectile shot whatever the incidence may be. The grille according to the invention wherein the outer blades is made an armored material while the inner blades made of a ductile material, the blades all being fixed to transverse members in the bearing ranges in such a way that they can be disassembled.

Abstract: A cover construction (10) for windows, including a generally rectangular housing member (20) which is affixed to, and projects outwardly from, a window frame (101) via a mounting flange (26) and further includes an angled roof panel (21), a floor panel (25), a pair of opposed side panels (22), (23) and a generally open front panel (24).

Abstract: A spring-loaded quick-release mechanism to a locking security grille is triggered by (i) manual activation, preferably through a foot switch, or (ii) fire, typically through a thermal fuse. Fins incorporated in, and/or affixed to the bars of, a security grille are preferably rotating, normally in phase, so as to serve as a louver or, when completely closed, an interlocked security shield, or panel. One locking release mechanism, which may optionally be quick release, has a sliding bar with alternate (i) extension and (ii) notch regions that respective engage the ends of solid, purely cylindrical, elongate prisms, normally cylindrical bars, to respective lock, and disengage, these prisms in a security grille. Finally, a security grille with standard universal retention assemblies variously serves to retain any, and any combinations, of tubular bars, solid bars, fins mounted to bars, and solid fins.

Abstract: The invention relates to a protective device against aggression.The protective device against aggression is designed to close the free space situated above the tray of a counter or cash-desk rapidly from below upwards.The closing means comprise a tray movable upwards from a lowered position in which it is substantially horizontal to a raised vertical position blocking said space.

Abstract: A security window has a non-transparent bullet resistant screen between the people on either side of the window. Because this screen cannot be seen through, an arrangement of mirrors (two on each side of the screen) is provided to reflect images from each side across to the other side. The customer and cashier each look into mirrors set at eye level on their respective sides of the screen and reflected images are directed to a point above the screen where two mirrors are arranged in a cavity. This cavity tends to act as a sounding box and permits sound to travel from one side of the screen to the other. The eye-level mirror on the cashier's side can be moved to a position where it merely reflects back the image reflected from the other side, in the event of an attack.

Abstract: An armor window through which air, sound and sight without inversion will pass freely yet sight can be selectively obstructed and at all times the flight of a propelled element at any angle will be obstructed by at least two spaced angle iron members with the further high probability of propelled elements, including harmful liquids, being substantially and safely deflected.
