1. floor board block that is used to be provided with the floor, this floor board block is a rectangle, promptly elongated or square;

  • Described floor board block (1) have a flat basically bottom surface (7), limit that flat basically end face is relative with the first and second couple who forms floor board block (1) edge (2-3 26-27), is characterized in that, floor board block has following combination of features;

    The edge on-at least the first pair of relative limit (2-3) is provided with coupling part (4-5), and each coupling part allows two such floor board block to interconnect;

    -these coupling parts are tongue (9 basically,

         31) and the form of groove (10,32), described groove (10,32) by top projection (22,42) and bottom projection (23,43) define, described top projection forms the upper wall surface of groove (10) and has a far-end, described bottom projection forms the lower wall surface of groove (10), described bottom projection (23,43) stretches out beyond the described far-end of top projection (22,42);

    The upper wall surface of-groove (10) comprises a flat contact surface (86), and under the connection status of two such floor board block (1), this contact surface (86) cooperates with the upper surface (85) of tongue (9,31);

    -coupling part (4-5) is provided with whole mechanical locking device, and the floor board block (1) that prevents two connections is along (2-3 26-27) separates with the direction (R) of the bottom surface (7) that is parallel to the floor board block (1) after being connected perpendicular to relevant edge;

    -described coupling part (4-5) and locking member are configured as the cutting edge profile, described profile be positioned at the plane that limits by the flat basically bottom surface (7) of floor board block (1) and the plane that limits by the flat basically end face of floor board block (1) between;

    -described locking member comprises a locking member (34,47) on described bottom projection (23,43), described locking member is formed in described bottom projection (23,43) groove of top (13,36) and at described tongue (9,31) following (12,35) projection (11,33) border, thus under the connection status of two such floor board block (1), the projection (11 of described one of them floor board block (1),

         33) groove (13,36) with another floor board block (1) cooperates;

    The border of-described groove (13,36) is made of two side wall surfaces, promptly is positioned at the side wall surface and the side wall surface that is positioned at nearside in distally;

    -described locking member is respectively at described bottom projection (23,43) and described tongue (9, qualification contact surface

         31) (38-39,73-74), described contact surface is as locking surface, under the connection status of two such floor board block (1), described locking surface prevents that floor board block (1) from separating, and is arranged on the locking surface (39 on the groove (10,32),

         73) the described side wall surface that is positioned at the distally by groove (13,36) forms;

    -be positioned at the position that this bottom projection (23,43) stretches out the far-end of described top projection (22,42) at the last locking surface (39,73) of described bottom projection (23,43);

    -coupling part (4-5) and locking member allow two such floor board block (1) to engage by rotation, and correspondingly can take apart;

    -from cross section, described tongue (9,31) and groove (10,32) are determined a center line, this center line is substantially in the upper wall surface of groove (10,32) and the centre between the lower wall surface;

    -the locking member (34) that constitutes groove (13, the

         36) border be arranged on bottom projection (23,43) is positioned at the below of described center line fully;

    The side wall surface that is positioned at near-end of-described groove (13,36) tilts, and extends towards the inboard of floor board block (1) from the bottom of groove (13,36) in the upward direction thus.
