    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, the upper part and the lower part extend parallel on either side of the notch or of the protrusion.

    Abstract: A floor panel includes male and female coupling means that are formed by at least one proximal groove that opens onto a lower face or upper face, respectively, of the panel and by a distal flexible tongue that extends from the end of the edge of the panel towards the lower face or upper face, respectively. The tongue has a proximal wall inclined at an angle with respect to a vertical plane towards the bottom and the outside of the panel and towards the top and the outside of the panel, respectively. The tongue of at least one of the male coupling means or female coupling means has a distal wall that includes, 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 the proximal groove of the corresponding female coupling means or male coupling means so as to form an end stop, avoiding vertical movement of a panel with respect to an adjacent panel. The flexible tongue of the female coupling means comprises a chamfered part that forms an angle of between 2° and 20° with respect to the main plane of the panel.

    Abstract: A joint structure includes a first floorboard and a second floorboard. The first floorboard and the second floorboard each includes: a top surface; a bottom surface; a first side surface; a second side surface; a third side surface; a fourth side surface; a first beveled tenon, the first beveled tenon including a first tenon face facing upwards; a first beveled mortise, the first beveled mortise including a first mortise face facing upwards; a second beveled tenon, the second beveled tenon including a second tenon face facing downwards; and a second beveled mortise, the second beveled mortise including a second mortise face facing downwards. The top surface is disposed substantially parallel to the bottom surface. The first side surface, the second side surface, the third side surface, and the fourth side surface are disposed substantially perpendicular to the bottom surface.
