Abstract:
1. A rectangular floor panel, comprising a core in the floor panel, made of a derived timber material, a decorative layer on a top side of the floor panel, pairs of opposite side edges on the floor panel, where at least one pair of side edges displays complementary, form-fitting hooked profiles, one of the complementary, form-fitting hooked profiles being a receiving hook extending vertically upward from a bottom side of the floor panel and, the other of the complementary, form-fitting hooked profiles, on the opposite side edge, being a retaining hook extending vertically downward from the top side of the floor panel, the retaining hook having a distal side surface with at least one elastically deformable horizontally projecting interlocking element, the retaining hook having a horizontal recess on a proximal side surface, the receiving hook having a receiving surface with at least one receiving pocket for receiving the projecting interlocking element of the retaining hook and at least one elastically deformable horizontally projecting interlocking hump, the interlocking hump being positioned above the pocket, on the receiving surface, the receiving hook having a distal side surface with a horizontally projecting interlocking element on the distal side surface, the retaining hook is lockable with the receiving hook by a locking vertical movement perpendicular to the plane of the floor panel, wherein the interlocking element of the retaining hook and the interlocking hump mutually elastically deform during the locking vertical movement, the projecting interlocking element of the receiving hook is received in and contacts the recess of the retaining hook and the interlocking element of the retaining hook and the top side of the floor panel are separated by a distance that, referred to the total thickness of the floor panel, corresponds to at least one-third of the total thickness of the floor panel, wherein the distal side surface of the retaining hook comprises first and second interlocking elements and a contact surface proximate the top side of the floor panel, the first and second interlocking elements being located below the contact surface such that the contact surface is interposed between the top side of the floor panel and the first and second interlocking elements, wherein the first interlocking element is located closer to the top side of the floor panel and projects horizontally farther from the distal side surface of the retaining hook as compared to the second interlocking element.
