Mechanical panel connection

A panel connection, particularly for flooring panels, comprising:

• a first panel (1) having a first side edge (5), the first side edge having a first upper lip (31) and a lower lip (33) forming a groove (35) that extends parallel to the first side edge (5),
• the groove (35) having a first surface (16) on the lower lip (33) extending at an upward incline with respect to a first top side (3) of the first panel (1),
• the groove (35) also having a second surface (14) on the upper lip (31) opposite the first surface (16),
• the first upper lip (31) having an end surface (13) at the distal end of the first upper lip (31) and the lower lip (33) having an end surface (18) at the distal end of the lower lip (33), the end surfaces (13, 18) being substantially aligned in the same plane,
• the first side edge (5) also having a third surface (11) and a fourth surface (12), the third surface (11) extending substantially perpendicular to the first top side (3) and the fourth surface (12) extending substantially parallel to the first top side (3);
• and
• a second panel (2) having a second side edge (6), the second side edge (6) having a tongue (32) extending parallel to the second side edge (6),
• the tongue (32) having a fifth surface (26) on the bottom thereof extending at an upward incline with respect to a second top side (4) of the second panel (2),
• the tongue (32) also having a sixth surface (24) forming the top thereof,
• the second side edge (6) also having a second upper lip (30) formed by a seventh surface (21) and an eighth surface (22), the seventh surface (21) extending substantially perpendicular to the second top side (4) and the eighth surface (22) extending substantially parallel to the second top side (4), the tongue (32) and the second upper lip (30) forming a second groove (37);
• wherein, in an interlocked state of the connection:
• the second and sixth surfaces (14, 24) rest against one another and the first and fifth surfaces (16, 26) rest against one another to keep the first and second side edges (5, 6) in contact with one another;
• the fourth and eighth surfaces (12, 22) rest against one another;
• and
• the third and seventh surfaces (11, 21) rest against one another.

• and
• a second panel (2) having a second side edge (6), the second side edge (6) having a tongue (32) extending parallel to the second side edge (6),
• the tongue (32) having a fifth surface (26) on the bottom thereof extending at an upward incline with respect to a second top side (4) of the second panel (2),
• the tongue (32) also having a sixth surface (24) forming the top thereof,
• the second side edge (6) also having a second upper lip (30) formed by a seventh surface (21) and an eighth surface (22), the seventh surface (21) extending substantially perpendicular to the second top side (4) and the eighth surface (22) extending substantially parallel to the second top side (4), the tongue (32) and the second upper lip (30) forming a second groove (37),
• the distal end (42) of the tongue (32) projecting beyond the distal end (21) of the second upper lip (30);
• wherein, in an interlocked state of the connection:
• the second and sixth surfaces (14, 24) rest against one another and the first and fifth surfaces (16, 26) rest against one another to keep the first and second side edges (5, 6) in contact with one another;
