Vertical jalousie // 2268981

FIELD: building, particularly devices providing defense against direct sun light.

SUBSTANCE: vertical jalousie comprises executive mechanism, fixed frame, odd-numbered and even-numbered fabric lamellas rotary installed in the frame, weights and hinged loops. Each odd-numbered and even-numbered fabric lamella have end with smooth edge and end with edge defined by periodic curve. Lower end of even-numbered lamella is provided with size and shape different from that of odd-numbered one. Weights of odd-numbered and even-numbered fabric lamellas are made of polystyrene and correspond to sizes and dimensions of lower edges of odd-numbered and even-numbered fabric lamellas. The weights are provided with metal inserts of different shape and weight.

EFFECT: improved light dissipation to create necessary light effect due to half-shade pattern.

SUBSTANCE: group of inventions relates to the field of construction, namely, to a frame structure of a window frame, which is a composite element of a wall or roof structure and is designed to communicate internal premises with the surrounding space, natural lighting of premises, their ventilation, protection against atmospheric and noise effects, and its precast unit - a leaf (a leaf element). For a "leaf" object - in a left of a window frame comprising two or more glass sheets connected to each other along the contour with a spacing frame, in the slot of which there are fittings installed designed to fix the leaf in the window frame, and frame structure cases attached to the external side of glasses along their contour to close external and internal ledges of the window frame, the spacing frame and frame structures of cases are produced as a result of separation into three parts of the frame element of the initial PVC shape. And for a "window frame" object - a window frame comprises a frame and leaf built into the window opening including two or more glass sheets connected to each other along the contour with a spacing frame, in the slot of which there are fittings installed designed to fix the leaf in the window frame, and frame structure cases attached to the external side of glasses along their contour to close external and internal ledges of the window frame, in which the spacing frame and frame structures of cases are produced as a result of separation into three parts of the frame element of the initial PVC shape. At the same time as a rule in the slot of the case closing the internal ledge there is a seal.

EFFECT: higher manufacturability of item design aimed at reduction of item production labour intensiveness and its prime cost.

SUBSTANCE: invention is related to the field of construction, namely to door designs, and may be used in industry for operation under higher load. Roll door comprises roller for winding and reeling of door curtain, facilities for collection of rope arranged near door aperture, drive, diverting facilities arranged with the possibility to carry out working stroke/stretching in case external load acts at curtain with rope wound and reeled from it, the first end of which is connected to lower part of curtain, from which rope passes in pulleys, and the second end is connected to facilities for its collection. Roll door is made with facilities that prevent working stroke of diverting facilities beyond a certain point, so that to preclude displacement of curtain in close position in case of load action at it.

EFFECT: invention makes it possible to increase door rigidity due to reduction of its buckling in vertical direction.

Protective grille // 2004751

FIELD: construction.

SUBSTANCE: system comprises, as a protective device, a metal lattice consisting of fencing elements in the form of two crossbars, at the ends of which through coaxial openings are made, and at least two vertical racks arranged between the crossbars and connected with them, with a distance therebetween of not more than 11 cm, and an installation kit. The installation kit includes four brackets, by means of which said lattice is installed from the outside of the window on the vertical surface of the window frame. Each bracket is represented by a three-dimensional piece made of a sheet workpiece, having a T- or L-shape in plan, the vertical and the horizontal elements of which are respectively the cantilever part and the support part of the bracket. On the edges of the support part, there are through openings for fixing screws, by means of which the bracket is fastened to the window frame. The longitudinal edges of the cantilever bracket part are bent each at the right angle away from the support part to form side flanges, each having at least one through opening coaxial to a similar through opening on the opposite side flange. In the cantilever bracket part, at least one through groove of the rectangular or circular shape is made, into which one end of the corresponding crossbar of the metal lattice is mounted and then fixed. Four plates are also included in the installation kit, that are mounted on the inside of the frame, with openings for the heads of fixing screws, by means of which said brackets are fastened to the window frame. Fixing elements are allso included in the installation kit, by means of mounting which through the through openings at the ends of the lattice crossbars the longitudinal movement of the lattice crossbar ends in said through grooves of the cantilever part of the brackets is limited.

EFFECT: increasing the reliability.
