Further, the first locking element 4 comprises a first locking surface 10 which is configured to cooperate with a second locking surface 11 on the first locking groove 5, for locking in the horizontal and the vertical direction.

[0044] The first locking surface 10 may be parallel or essentially parallel to the second locking surface 11.

[0045] A first guiding surface 14 may be comprised on an upper part of the first edge 1, which first guiding surface 14 cooperates with a second guiding surface 15 on the lower edge of the tongue 8 during the vertical displacement 27.

[0046] The tongue 8 on the second edge 2 may comprise an upper locking surface 16 which is configured to cooperate for locking in a vertical direction with a lower locking surface 17 of an upper lip 26 of the tongue groove 7.

[0047] The locking element 4 may comprise a third guiding surface 18 and the locking groove 5 may comprise a fourth guiding surface 19. These features are configured to cooperate during the vertical displacement 27 of the second edge 2 relative to the first edge 1 for assembling the second edge 2 to the first edge 1, as shown in FIG. 1B.

[0048] The first guiding surface 14 may be parallel or essentially parallel to the second guiding surface 15.

[0049] The third guiding surface 18 may be parallel or essentially parallel to the fourth guiding surface 19.

[0063] The third edge 3 may comprise a third locking element 24 configured to cooperate with a third locking groove 25 on the first edge 1 for locking in a horizontal direction.

[0064] The third edge 3 may be assembled to the first edge 1 by an angling motion, which is shown in FIGS. 2A and 2B.

[0065] The horizontal lockings as specified above may be an advantage, especially for panels with a locking in a resilient material. The multiple horizontal lockings may decrease the risk of unlocking and a separation of the first 1 and third 3 edges.

[0066] A locked position of the first edge 1 and the third edge 3 is shown in FIG. 2C.

[0067] The first locking surface 10 is positioned below the third locking surface 12.

[0068] The third locking surface 12 is positioned below the third guiding surface 18.

[0069] Enlargements of the first locking element 4 are shown in FIGS. 6A-6E.

[0070] An angle 31 between the first 10 and third 12 locking surface may be within the range of about 5 to about 30, preferably within the range of about 10 to about 25, or preferably about 17.

[0071] An angle 32 between the third locking surface 12 and third guiding surface 18 may be within the range of about 10 to about 40, preferably within the range of about 20 to about 30, or preferably about 25.

[0072] An angle 33 between the first locking surface 10 and an upper surface of the first 41 or second 42 panel may be within the range of about 70 to about 85, preferably within the range of about 75 to about 80, or preferably about 77.

[0073] An angle 34 between the third locking surface 12 and an upper surface of the first 41 or second 42 panel may be within the range of about 50 to about 85, preferably within the range of about 60 to about 75, or preferably about 67.

[0074] An angle 35 between the third guiding surface 18 and an upper surface of the first 41 or second 42 panel may be within the range of about 25 to about 60, preferably within the range of about 35 to about 50, or preferably about 42.

[0075] The set of panels according to embodiments of the present invention may provide an increased locking strength of the panels due to the multiple locking surfaces. An improved locking together of the panels may be critical for keeping the panels in position, also when being subject to forces by subject matter in motion on the panels.

[0076] The set of panels according to embodiments of the present invention may also be easier to assemble compared to known sets of panels due to the guiding surfaces. An improved guiding may be critical for assembling panels having surfaces with a high friction and particularly, if the panel edges comprise a less elastic material. Without the improved guiding such panels may be difficult to assemble or the panels or part of the panel, e.g., the tongue may break during the assembling. The set of panels according to embodiments of the present invention also provide a more compact junction between panels and thereby a reduced amount of panel material going to waste.

[0077] The set of panels according to embodiments of the present invention may be assembled in different patterns. One example is a herringbone pattern, wherein a first 41 and second 42 panel are assembled, as shown in FIGS. 4A-4B. When assembling the panels in a herringbone pattern, the second edge 2 of the second panel 42 is to be connected vertically to the first edge 1 of the first panel 41.

[0078] Another example is a modular pattern, in which the panels are assembled parallel to each other, as shown in FIGS. 5A-5B. When assembling the panels in a modular pattern either only multiples of the first panel 41 or only multiples of the second panel 42 are to be connected to each other in each row of panels. When assembling the panels in a modular pattern, the first edge 1 of a first panel 41 is connected to the third edge 3 of a first panel 41, or, alternatively, the first edge 1 of a second panel 42 is connected to the third edge 3 of a second panel 42.

[0079] The first panel 41 may comprise, in a clockwise direction, the first edge 1, the first edge 1, the second edge 2, and the third edge 3, as shown in FIG. 3A.

[0080] The second panel 42 may comprise, in a clockwise direction, the second edge 2, the first edge 1, the first edge 1, and the third edge 3, as shown in FIG. 3B.

[0081] The first 41 panel and the second 42 panel may have a thickness in the range of about 3 mm to about 12 mm.

[0082] The embodiments described above may be resilient panels. The resilient panels may comprise a core comprising thermoplastic material. The thermoplastic material may be foamed.

[0083] The thermoplastic material may comprise polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof. The core may be formed of several layers.

[0084] The embodiments described above may comprise a decorative layer, such as a decorative foil comprising a thermoplastic material. The thermoplastic material of the decorative layer may be or comprise polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof. The decorative foil is preferably printed, for example by direct printing, rotogravure, or digital printing.

[0085] The embodiments described above may comprise a wear layer such as a film or foil. The wear layer may comprise thermoplastic material. The thermoplastic material may be polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof.

[0086] The embodiments described above may comprise a wood base core, such as HDF, MDF or plywood.

[0087] The first panel and the second panel may be configured to be disassembled by downwardly rotating the first and/or the second panel.
