PANEL AND COATING OF FLOOR Russian patent published in 2012 - IPC E04F15/02 

FIELD: construction.

SUBSTANCE: floor panel with a face surface comprises four edges, opposite pairs of which comprise corresponding retention profiles to connect panels of single type at all four edges. Retention profiles of the first pair of edges are connected by means of insertion at an angle, and retaining profiles of the second pair of edges are arranged in the form of coupled hook-shaped elements. On each of hook-shaped elements the neighbouring panel is connected substantially by means of motion executed in the plane perpendicularly to the panel plane, provided that at least one of hook-shaped elements of the second pair of edges there is a separate vertically locking element, which at least partially enters into a track of connection of hook-shaped elements. During a connecting motion of hook-shaped elements of two panels, a vertically locking element automatically comes out of the connection track to release it, and in the engaged position of the hook-shaped elements it automatically again enters the track connection due to a springy action. To simplify dismantling, it is provided that coupled hook-shaped elements are arranged as capable of unlocking joined panels from their engaged and vertically blocked condition, at the same time at least one panel is arranged as capable of rotation along the axis stretching in the zone of engaged edges in a direction, in which unlocked position is achieved. Face surfaces of panels in the unlocked position form an angle between each other that is less than 180°.

EFFECT: reduced labour inputs in assembly and disassembly of a floor coating.
