FLOORING CONSISTING OF PANELS MECHANICALLY ATTACHED TO EACH OTHER, AND MANUFACTURING METHOD OF SUCH PANELS, AS WELL AS METHOD FOR THEIR LAYING Russian patent published in 2015 - IPC E04F15/02 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to flooring. Flooring consists of panels having a possibility of being mechanically locked to each other on their end faces by means of locking members. On the end face of the first panel there is an undercut retaining slot passing in longitudinal direction for arrangement in it of a locking member. The locking member projects with several tongues located at some distance from each other out of the end face, thus entering pockets of the undercut locking slot in the opposite end face of the adjacent panel. Pockets are open to the lower side and the end face of the adjacent panel. The locking member is made so that when one of its ends is being moved inside the retaining slot, it can be at least partially offset from the pockets in the direction of the locking slot, thus preventing the panels against tension force acting in the direction of panel laying plane (V).

EFFECT: improvement of the design.
