Panel

Panel (1， 4， 5) comprising a panel top side (1a) and a panel bottom side (1b) as well as at least four panel edges， which are opposite each other in pairs， with complementary retaining profiles provided in pairs on the panel edges， which fit one another in such a way that panels of the same type can be fastened to one another， wherein at least one of the retaining profile pairs is provided with hook profiles， namely on one panel edge with a receiving hook (6) and on the opposite panel edge with a locking hook (7)， the receiving hook (6) having a receiving edge (8) directed towards the panel top side (1a) and a receiving groove (9) open to the panel top side and the locking hook (7) is provided with a locking edge (10) directed towards the underside of the panel (1b) and with a locking groove (11) open to the underside of the panel (1b)， the receiving edge (8) having an inside， which faces the receiving groove (9)， and this inside serves as a lower locking surface (12)， and to match the locking edge (10) has an inside facing the locking groove (11) and this inside as a corresponding upper locking surface (13 )， with the proviso that both the lower locking surface (12) and the upper locking surface (13) are inclined in relation to the perpendicular (L) on the upper side of the panel (1a)， that they are aligned parallel to each other in the locked state and can touch each other， the inclination of the locking surfaces (12， 13) being selected so that the normal vector (N) on the lower locking surface (12) intersects the panel top (1a) and the normal vector (N) intersects the underside of the panel (1b) on the upper locking surface (13)， a lower catch (14) comprising a first catch means (15， 15a) being provided， which is arranged on an outer side (8a) of the receiving edge (8)， and the lower catch (14) comprises a corresponding second catch means (16， 16a) which is arranged on a set back groove flank (11a) of the locking groove (11)， wherein at least a portion (8b) of the upper side of the receiving edge (8) runs inclined downwards in the direction of the outside (8a) of the receiving edge (8)， wherein at least a section (11b) of the groove base of the locking groove (11) is adapted in a complementary manner to the inclination of the section (8b) of the upper side of the receiving edge (8)， with at least one free space (23， 24) between the lower side (10a) the locking edge (10) and the groove base (9a) of the receiving groove (9) is provided， and in the locked state a gap (25) is provided between the outside (8a) of the receiving edge (8) and the groove flank (11a) of the locking groove (11) is.
