FLOOR DIRT-PROOF COATING Russian patent published in 2021 - IPC A47L23/22 

FIELD: building materials.

SUBSTANCE: floor dirt-proof coating is formed by load-bearing elements in the form of longitudinal parallel modules connected to each other on adjacent sides through fasteners. Each load-bearing element is equipped with shock-absorbing inserts and is made with a support part and longitudinal grooves for installing a cleaning insert, a shape of a cross-section of which corresponds to a shape of a cross-section of longitudinal grooves of the load-bearing element. Load-bearing elements are interconnected by means of fasteners in the form of a kinematic pair consisting of a bracket placed with the possibility of rotational movement in a hollow cylindrical element. Each load-bearing element is made in the form of a frame structure formed by side profile walls and the support part. In side profile walls, through holes for the passage of brackets and longitudinal grooves are made, designed to accommodate a cleaning insert and a fixing bar, respectively, installed in grooves with the possibility of movement, the supporting part is equipped with stiffeners adjacent to the fixing bar equipped with clamps for shock-absorbing inserts to form a volume for placing elements of brackets, and the hollow cylindrical element, when connecting load-bearing elements, is located between their adjacent sides.

EFFECT: obtaining floor dirt-proof coating.
