ROLLER SHUTTER Russian patent published in 2022 - IPC E06B9/11 

FIELD: closing openings elements.

SUBSTANCE: invention relates to the field of fixed or movable elements for closing openings in buildings, vehicles or other devices. The effect is achieved due to the fact that the roller shutters, including a shaft with a drive, slats, interconnected by connecting elements into a web, characterized in that a transition element is mounted on the shaft, made in the form of a regular polyhedral prism containing an even number of main faces, each second face which is made along the width of the smaller faces adjacent to it with the possibility of placing a connecting element on it, and the remaining faces are made with the possibility of placing lamellas along them, while the first face of the transition element for placing the first connecting element with the first lamella on it is recessed relative to the edge, along which the first lamella is placed, forming a recess between the said faces, the opposite side of the face for accommodating the first connecting element is made protruding above the surface of the face adjoining it for the last lamella of the first row, the second face of the transition element for accommodating the second connection the body element is made adjacent to adjacent faces to accommodate lamellas without the formation of any protrusions or recesses, and the third and fourth faces of the transition element for accommodating the connecting elements are made in the form of protruding rectangular areas, for connecting the lamellas into a web, the connecting elements are made symmetrically with C-shaped hooks, which, being a continuation of the upper and lower longitudinal edges of the connecting elements, form hooks from below, and from above, the clamps with the possibility of interengaging the mentioned hooks with the grooves of the lamellas made along the lamellas, and holding the lamellas inside the connecting elements by the clamps, while the surfaces of the clamps and hooks facing each other are made parallel, with the possibility of forming supporting surfaces for the lamella, and the outer surface of the clamp is made under angle with the possibility of forming a supporting surface for the lamella of the next row of lamellas when laying them on the transition elements, a hole is made on the outer side in the center of the connecting element with the possibility of mounting a plug into it, while mentioned The plug is made with the possibility of entering the lamellas, mounted from both ends of the transition element to fix them and prevent displacement of the transition elements in the grooves of the lamellas; -shaped hooks, similar to the connecting element.

EFFECT: increasing the reliability of roller shutters.
