Abstract
In a male and female coupling means of a floor panel the male coupling means is formed of at least one proximal groove and of a flexible distal tongue. The female coupling means is formed of at least one proximal groove and of a flexible distal tongue. The flexible distal tongue of the male coupling means has a proximal wall inclined at an angle β with respect to a vertical plane towards the bottom of the panel and towards the outside of the panel, while the flexible distal tongue of the female coupling means has a proximal wall inclined at an angle α with respect to a vertical plane towards the top of the panel and towards the outside of the panel. The flexible distal tongue of at least one of the male or female coupling means has a distal wall comprising, at least, a protrusion or a notch that is able to engage with a notch or a protrusion formed in or on a proximal wall of at least one proximal groove of corresponding female or male coupling means of an adjacent panel so as to form an end stop, avoiding vertical movement of the panel with respect to the adjacent panel. The proximal wall of the proximal groove of the male coupling means comprises an upper part, and a lower part, …
