Description

Technical Field

[0001] This disclosure relates to building panels, and more specifically, aspects of this disclosure relate to locking systems for building panels, and more specifically, some aspects of this disclosure relate to the fluid permeability of such locking systems. Background Technology

[0002] Known architectural panels include a first mechanical locking system, typically along opposing long sides, for assembling adjacent panels into a locked position by folding displacement. Panels also known to include a second mechanical locking system, typically along opposing short sides, for assembling adjacent panels into a locked position by bending the vertical displacement of a displaceable locking tongue.

[0003] While these known panels may represent well-functioning architectural panels, there is still room for improvement in the technical field. Summary of the Invention

[0004] One object of at least one embodiment of this disclosure is to reduce or at least mitigate the drawbacks of known systems.

[0005] In a first aspect, an architectural panel, such as a floor panel, is provided, comprising a first mechanical locking system at respective first and second opposing edges, e.g., long edges. The first mechanical locking system includes a tongue groove at one of the first or second opposing edges, configured preferably to receive a locking tongue at the other of the first or second edges by folding displacement for vertically locking adjacent substantially identical panels in an assembled position. The locking tongue includes a substantially horizontal and preferably upward-facing upper surface. A second mechanical locking system is formed on respective third and fourth opposing edges, e.g., short edges. The second mechanical locking system includes a wedge-shaped groove at one of the third or fourth edges, configured preferably to receive a displaceable locking tongue by vertical displacement, e.g., vertical folding, for vertically locking adjacent substantially identical panels in an assembled position. The displaceable locking tongue is configured to displace in a displacement groove located at the other of the third or fourth edges. In one embodiment, the displacement groove includes an upper wall. This upper wall is preferably located vertically below the upper surface of the locking tongue.

[0006] In the second aspect, a set of architectural panels is provided according to either aspect.

[0029] Specific embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the disclosure thorough and complete, and to fully convey the scope of the disclosure to those skilled in the art. The terminology used in the detailed description of the embodiments illustrated in the drawings is not intended to be limiting of the disclosure. In the drawings, the same numerals refer to the same elements.

[0030] Figure 1A-1B A set of known panels 1′ assembled in the locked position is shown, with the front surface 15′ of the panels 1′ facing the observer. Figure 4A Details of a known architectural panel 1′ are shown. A first mechanical locking system 50′ is formed on the respective first edge 11′ and second edge 12′ of panel 1′, for example, on the long side, for horizontal and vertical locking of adjacent panels by folding displacement. The second edge 12′ includes a locking tongue 121′ configured to be received in a tongue groove 111′ by folding displacement for vertical locking of the panel.

[0031] Figure 4B Further details of the known architectural panel 1′ are shown. A second mechanical locking system 60′ is formed on the corresponding third edge 13′ and fourth edge 14′ of panel 1′, for example on the short edge, to be used for horizontal and vertical locking of adjacent panels by vertical displacement.

[0032] The second mechanical locking system 60′ may include a wedge-shaped groove 141′ at one of the third or fourth edges 13′, 14′, the wedge-shaped groove 141′ being configured to receive a movable locking tongue 131′ of the other of the third or fourth edges 13′, 14′ for vertically locking adjacent panels in the assembled position.

[0033] The displaceable locking tongue 131′ can be configured to displace in the displacement groove 133′ of the other of the third or fourth edges 13′, 14′. To more clearly illustrate the features of the known architectural panel 1′, the known panel 1′ is shown in... Figure 2B and 4B The movable locking tongue 131′ is omitted.

[0034] The displacement groove 133 can be inclined vertically downward toward the rear surface 16 of the panel 1 in the direction of entering the displacement groove / towards the center of the panel 1, or inclined upward toward the front surface 15 of the panel 1.

[0035] like Figure 1B As schematically shown, when assembled in the locked position by the second mechanical locking system 60', a gap 5' is formed in the longitudinal direction of the assembled known panel 1' between the locking tongues 121' of each panel. When adjacent panels are assembled by the second mechanical locking system 60', the gap 5' is formed between a first portion 1213' at the first end of the locking tongue 121' and a second portion 1214' at the opposite second end of the locking tongue 121' of the adjacent panel 2. The gap 5' can typically be about 4.5 mm, or approximately corresponds to the size of the upper wall 135' of the displacement groove 133. The origin of the gap 5' may be a result of one or more features of the first and / or second locking systems 50', 60', such as the vertical position of the locking tongues 121' and the displacement groove 133'. In particular, the gap 5' may be a manufacturing result of such features of the first and / or second locking systems 50', 60'.

[0036] In a non-limiting example, the locking system 50', 60' can be formed by feeding the panel 1' through one or more cutting tools (e.g., rotary cutting tools) along the feed direction, whereby the one or more cutting tools can form at least a portion of the locking system along one of the edges 11', 12', 13', 14'.

[0037] Therefore, as Figure 2A and 2B As shown, the first locking system 50' and the second locking system 60' may overlap at corresponding corners of the panel 1'. Specifically, at least a portion of the first locking system 50' and the second locking system 60' may intersect at corresponding corners of the panel 1', such as... Figure 2A and 2BAs shown.

[0038] Reference Figures 4A-4B Because the distance D1′ between the front surface 15′ of the panel and the upper surface 122′ of the locking tongue 121′ is greater than the distance D2′ between the front surface 15′ and the upper wall 135′ of the displacement groove (e.g., the uppermost part of the upper wall 135′), when forming the displacement groove 133′, which may involve cutting material from the panel to create a material void, a void may be created at its intersection or crossing with the upper surface 122′ of the locking tongue 121′, for example at the corner B′ between the second edge 12′ and the third edge 13′. Figure 2A As shown.

[0039] To convey the prior art, projection H1′ schematically shows the projection of the upper surface 122′ of the locking tongue 121′ onto the length or longitudinal direction L of the panel (i.e., the projection along the upper surface 122′).

[0040] Projection W2′ schematically shows the projection of the upper wall 135′ of the displacement groove 133′ onto the width or transverse direction T of the panel (i.e., the projection along the upper wall 135′).

[0041] Projection W1′ schematically shows the projection of the inner wall 136′ of the displacement groove 133′ onto the width or transverse direction T of the panel (i.e., the projection along the inner wall 136′).

[0042] Projection O1′ schematically shows the projection of the opening 137′ of the displacement groove 133′. The opening 137′ is formed by the outermost edge of the upper wall 135 and the outermost edge of the lower wall 134 of the displacement groove 133′.

[0043] It can be deduced that the protrusions W2′ and H1′ intersect, meaning that a portion of the locking tongue 121′, including the upper surface 122′, cannot be formed or has been removed during manufacturing, thus allowing the gap 5′ to be formed. The gap 5′ may include a first portion 5a′ and a typical second portion 5b′, as will be explained herein. Therefore, when adjacent panels are assembled along their short sides, as... Figure 1B As shown, a considerable gap 5' may exist between the upper surfaces 122' of the corresponding locking tongues 121' of adjacent panels. Thus, fluid migrating from the upper surface 15' to the locking tongue 121', for example when assembled with the first edge 11' of an adjacent panel, can pass through the engagement edge 12' of the first locking system 50'. Therefore, fluid may migrate from the front surface 15' of the panel to the rear surface 16', for example, under the influence of gravity.

[0044] In other words, the displacement groove 133' is at least partially formed in the space that would otherwise be formed in the core material of the locking tongue 121' of the first locking system 50', wherein the displacement groove 133' may be formed by one or more cutting tools (e.g., rotary cutting tools) and thus constitute a void in the material (e.g., the core material of the building panel 1'). In particular, the displacement groove 133' may be at least partially formed in the space in which at least a portion of the upper surface 122 of the locking tongue 121' of the first locking system 50' would otherwise be formed in the core material.

[0045] Projection O2′ schematically shows the projection of the opening 144′ of the wedge groove 141′ onto the transverse direction T of the panel 1′. The opening 144′ is formed by the upper outermost edge 142′ and the lower outermost edge 143′ of the wedge groove 141′. It can be deduced that the protrusions O2′ and H1′ intersect, which means that a portion of the locking tongue 121′, including a portion of the upper surface 122′, cannot be formed due to lack of material, or has been removed during the manufacturing of the displacement groove. Thus, the second part 5b′ of the gap 5′ can be formed. Therefore, when the two panels are assembled along the short side, as Figure 1B As shown, a second portion 5b' of the gap 5' can be formed between the corresponding upper surfaces 122' of the locking tongues 121' of adjacent panels. Therefore, for example, when assembled with the first edge 11' of an adjacent third panel (not shown), fluid migrating from the upper surface 15' to the locking tongue 121' may pass through the engagement edge 12' of the first locking system 50'.

[0046] Refer again Figures 4A-4B The distance D1′ between the upper surface 15′ of the panel 1′ and the upper surface 122′ of the locking tenon 121′ is greater than the distance D3′ between the upper surface 15′ of the panel 1′ and the upper edge 142′ of the wedge groove 141′. Therefore, as Figure 3B As shown, the projection H1′ of the upper surface 122′ in the longitudinal direction L of the panel 1′ intersects the projection O2′ of the wedge groove 141′ in the transverse direction T of the panel at a corner C′. The corner C′ can be the corner between the first locking system 50′ of the second edge 12′ and the second locking system 60′ of the fourth edge 14′. Therefore, when the wedge groove 141′ is formed, at least a portion of the upper surface 122′ is removed by the one or more cutting tools (not shown).

[0047] Therefore, from Figure 2B It can be concluded that the upper surface 122′ intersects the upper wall 135′ of the displacement groove 133′ in three-dimensional space, such as X, Y, Z.

[0048] from Figure 4BIt can be concluded again that the upper surface 122′ intersects the upper wall 135′ of the displacement groove 133′ in a two-dimensional space, for example, in the XZ plane, so a portion of the upper surface 122′ is removed by forming the upper wall 135′ of the displacement groove 133′.

[0049] Therefore, from Figure 3B It can be concluded that the upper surface 122′ intersects the wedge-shaped groove 141′ in three-dimensional space, such as X, Y, Z.

[0050] from Figure 4B It can be concluded again that the upper surface 122′ intersects the wedge groove 141′ in a two-dimensional space, for example, in the XZ plane, and thus a portion of the upper surface 122′ is removed by forming the wedge groove 141′.

[0051] Figures 5A-5B Images 6A-6B, 7A-7B, 8A-8B, and 9A-9B illustrate embodiments of panel 1 according to exemplary embodiments of the present disclosure.

[0052] Panel 1 can be floor panel, wall panel, ceiling panel, or furniture panel.

[0053] Panel 1 may include a core 3 containing a core material. The core may be particleboard, wood substrate block, such as wood, HDF, or MDF.

[0054] Panel 1 may include one or more surface layers, such as a finish, a thermosetting adhesive, or a combination thereof, including but not limited to melamine-formaldehyde. The surface layers may be disposed above and / or below the core 3.

[0055] Figure 5A Details of a first mechanical locking system 50 according to an embodiment of the present disclosure are shown. The first mechanical locking system 50 may be formed on respective first edges 11 and second edges 12 of the panel 1, for example, on the long side, to lock adjacent panels horizontally and vertically by folding displacement. Figure 5B Details of a second mechanical locking system 60 are shown, which is formed on the respective third edge 13 and fourth edge 14 of the panel 1, for example on the short edge, to be used for horizontal and vertical locking of adjacent panels by vertical displacement.

[0056] For the purpose of conveying exemplary innovative aspects of this disclosure, in Figure 5B and 7B The movable locking tongue 131 is omitted. However, the movable locking tongue 131 is... Figure 9B As shown in the image.

[0057] Reference Figures 5A-5BThe distance D2 between the front surface 15 and the upper wall 135 of the displacement groove (e.g., the uppermost part of the upper wall 135) is preferably greater than the distance D1 between the front surface 15 of the panel 1 and the upper surface 122 of the locking tongue 121. The formation of the displacement groove 133, which typically involves cutting material from the panel to create a material gap, will not create a gap at the location of the upper surface 122 of the locking tongue 121, for example, at the corner B between the second edge 12 and the third edge 13, when it intersects with the upper surface 122 of the locking tongue 121. Figure 7A As shown.

[0058] To convey an exemplary aspect of the innovation of this disclosure, projection H1 schematically shows the projection of the upper surface 122 of the locking tongue 121, for example, in the length direction and / or longitudinal direction L of the panel (i.e., the projection along the upper surface 122).

[0059] Projection W2 schematically shows the projection of the upper wall 135 of the displacement groove 133, for example, in the width direction W and / or the lateral direction T of the panel 1 (i.e., the projection along the upper wall 135).

[0060] Projection W1 schematically shows the projection of the inner wall 136 of the displacement groove 133, for example, in the width direction W and / or the lateral direction T of the panel 1 (i.e., the projection along the inner wall 136).

[0061] Projection O1 schematically shows the projection of the opening 137 of the displacement groove 133, for example, in the width direction W or the lateral direction T of the panel 1.

[0062] The opening 137 is formed by the outermost edge of the upper wall 135 and the outermost edge of the lower wall 134 of the displacement groove 133. Figure 7B It can be deduced that protrusions W2 and H1 do not intersect, which allows a portion of the locking tongue 121, including the upper surface 122, to be formed and / or not removed during the manufacture of the displacement groove 133, wherein said portion of the locking tongue 121, including the upper surface 122, is located at the two-dimensional intersection between the displacement groove 133 and the upper surface 122 when viewed from the vertical direction V. The vertical perspective view can be of the panel 1 viewed from above, for example, facing its front surface 15. Thus, the size of the second portion 5b of the gap 5 can be reduced, or preferably the second portion 5b is substantially not formed. Therefore, when the two panels 1, 2 are assembled along the short sides 13, 14, as Figure 6BAs shown, the transition between the upper surfaces 122 of the corresponding panels 1 and 2 can be continuous, for example, with essentially no gap between the upper surfaces 122 of the corresponding locking tongues 121 of adjacent panels 1 and 2. Thus, compared to the known panel 1', the locking tongue 121, particularly its upper surface 122, can have a longer extension, for example, in the longitudinal direction L. As shown here, compared to the known panel 1', the upper surface 122 of the locking tongue 121 can have a longer extension at its two opposite ends, for example, in the longitudinal direction L.

[0063] Therefore, when configured in the assembly position by the second mechanical locking system 60, the corresponding locking tongues 121 of the adjacent panels 1 and 2 can come into contact.

[0064] Therefore, when configured in the assembly position by the second mechanical locking system 60, the corresponding upper surfaces 122 of the adjacent panels 1 and 2 can be substantially adjacent to each other.

[0065] Therefore, for example, when such Figures 6A-6B When assembled with the first edge 11 of the adjacent panel, fluid that may migrate from the upper surface 15 to the locking tongue 121 under the influence of gravity can be substantially prevented from passing through the engagement edge 12 of the first locking system 50.

[0066] In other words, the displacement groove 133, which can be formed by one or more rotary cutting tools and is therefore a void material (e.g., the core material of the building panel 1), is at least partially formed in the core material below the space of the locking tongue 121 forming the first locking system 50, particularly below the upper surface 122 of the locking tongue 121.

[0067] Figures 6A-6B A set of panels 1 assembled in a locked position is shown, with their front surface 15 facing the observer. The front surface 15 may be the front surface of a surface layer 15a, such as a decorative surface layer. A corresponding balancing layer 16a may be disposed on the opposite back side of the panel 1.

[0068] refer to Figure 6B , 7B According to this disclosure, the upper surfaces 122 of the corresponding adjacent panels 1 and 2 can advantageously extend substantially adjacent to each other.

[0069] The first end of the locking tenon 121 in the longitudinal direction of the panel 1 may include a first portion 1213.

[0070] The second end of the locking tenon 121, which is opposite to the first end of the locking tenon 121 in the longitudinal direction of the panel 1, may include a second part 1214.

[0071] The first portion 1213 of the locking tenon 121 may be the outer portion and / or end portion of the locking tenon 121, such as the outermost portion of the locking tenon 121, or the end portion of the locking tenon 121 at the corner between the second edge 12 and the third edge 13. The first portion 1213 may include the outermost portion or edge of the upper surface 122.

[0072] The first portion 1213 of the locking tenon 121 may include a surface, such as a generally vertical surface. The first portion 1213 may include edges, such as the outermost edge of the locking tenon 121 and / or the outermost edge of the upper surface 122.

[0073] The first part 1213 may include a surface and at least one edge.

[0074] The second portion 1214 of the locking tenon 121 may be the outer portion and / or end portion of the locking tenon 121, such as the outermost portion of the locking tenon 121, or the end portion of the locking tenon 121 at the corner between the second edge 12 and the fourth edge 14. The second portion 1214 may include the outermost portion or edge of the upper surface 122.

[0075] The second portion 1214 of the locking tenon 121 may include a surface, such as a generally vertical surface. The second portion 1214 may include edges, such as the outermost edge of the locking tenon 121 and / or the outermost edge of the upper surface 122.

[0076] Part 2, 1214 may include a surface and at least one edge.

[0077] The first part 1213 may include a first end portion at the first end of the locking tongue 121, for example in the longitudinal direction L of the panel 1 and / or along the X axis.

[0078] The second part 1214 may include a second end portion at the second opposite end of the locking tongue 121, which is in the longitudinal direction L of the panel 1 and / or along the X axis, for example, the end portion of the locking tongue of the panel 1 opposite to the first end portion of the locking tongue 121 of the panel 1.

[0079] Part 1213 and Part 1214 may come into contact at the assembly positions of adjacent panels 1 and 2.

[0080] The first part 1213 and the second part 1214 can be pre-tensioned at the assembly position of adjacent panels 1, 2, for example, pressed against each other.

[0081] The first part 1213 and the second part 1214 can be formed in the core material of the panel 1.

[0082] The first part 1213 and the second part 1214 can be pre-tensioned at the assembly position of adjacent panels 1, 2, for example, pressed against each other to deform the material of the core 3.

[0083] The first part 1213 and the second part 1214 may be configured to obtain a clearance DS of sufficient size to ensure that the corresponding surface layers 15a of the assembled panels 1, 2 are continuous and / or will not be pulled apart.

[0084] refer to Figure 7B The first portion 1213 can be configured to be flush with the upper portion 138. The upper edge portion 138 can be adjacent to the displacement groove 133.

[0085] refer to Figure 8B The second portion 1214 can be configured to be flush with the upper portion 148. The upper edge portion 148 can be adjacent to the wedge-shaped groove 141.

[0086] Fluid flow may cause the core material 3 to expand, which may reduce the size of the clearance DS.

[0087] In some embodiments, for example due to manufacturing tolerances, it is advantageous to design the panel 1 to obtain a small clearance DS between the first portion 1213 and the second portion 1214 when adjacent panels are assembled by the second mechanical locking system 60.

[0088] In a non-limiting example, excessive pretension or preload combined with the rigid core material may cause contact between 1213 and 1214 that results in the third and fourth edges of the corresponding adjacent panels 1 and 2 being pushed apart from each other when the panels 1 and 2 are assembled via the second locking system 60. This could, as a result, create gaps between the surface layers of the panels, which could distort the visual appearance of the floor and / or negatively impact waterproofing.

[0089] In any respect, the clearance DS can be in the range of 0.00 to +0.50 mm, preferably 0 to +0.30 mm, for example +0.03 to +0.15 mm, more preferably 0.00 to +0.05 mm.

[0090] In any respect, the clearance DS can be at least partially within a negative range of -0.05 to +0.10 mm. Such a range can indicate a certain degree of pretension.

[0091] The clearance DS can be adjusted based on the material properties of the core 3. The core material can be wood-based, HDF, MDF, etc. In particular, the degree of pretension can be adjusted based on properties related to the hardness of the core material 3 and / or properties related to the expansion characteristics of the core material 3.

[0092] The degree of pretension, i.e., the negative value of DS as described above, can be adjusted based on the characteristics of the core material 3. In particular, the degree of pretension can be adjusted based on characteristics related to the hardness of the core material and / or characteristics related to the expansion characteristics of the core material and / or characteristics related to the deformation characteristics of the core material.

[0093] The upper wall 135 and / or lower wall 134 of the displacement groove 133 may be inclined, for example, towards the rear surface 16 of the panel 1.

[0094] exist Figure 8B In the diagram, projection O2 schematically shows the projection of the wedge-shaped groove opening 144 onto the transverse direction T of the panel 1. The wedge-shaped groove opening 144 is formed by the upper outermost edge 142 and the lower outermost edge 143 of the wedge-shaped groove 141. It can be deduced that the protrusions O2 and H1 do not intersect, which allows a portion of the locking tongue 121, including the upper surface 122, to be formed or not removed when forming the wedge-shaped groove 141. Therefore, when the two panels are assembled along their short sides, as... Figure 6B As shown, the upper surfaces 122 of the corresponding locking tongues 121 of adjacent panels 1 and 2 can be substantially abutted, for example, directly abutted. In other words, thus, when configured in the assembled position by the second mechanical locking system 60, the corresponding upper surfaces 122 of adjacent panels 1 and 2 can be substantially abutted.

[0095] Therefore, for example when assembled with the first edge 11 of an adjacent panel, fluid migrating from the upper surface 15 to the locking tongue 121 is substantially prevented from passing through the engagement edge 12 of the first locking system 50.

[0096] Reference Figure 7B and Figure 8B The X-axis can be the primary axis, and the longitudinal or length direction of panel 1 can extend along the X-axis. The Y-axis can be the secondary axis, and the transverse or width direction of panel 1 can extend along the Y-axis. The Z-axis can be the third axis, and the thickness direction of panel 1 can extend along the Z-axis. X, Y, and Z can be orthogonal.

[0097] Therefore, refer to Figure 7B The upper surface 122 and the upper wall 135 of the displacement groove 133 do not intersect in three-dimensional space, such as X, Y, Z.

[0098] Reference Figure 5B The upper surface 122 and the upper wall 135 of the displacement groove 133 do not intersect in the two-dimensional space of the XZ plane. Therefore, the upper wall 135 of the displacement groove 133 can be formed without cutting off the outermost part of the upper surface 122 at the corner B, or alternatively, the outermost part of the upper surface 122 that overlaps with the upper wall 135 in the XY plane can be formed.

[0099] However, from Figure 7B It can be concluded that the upper surface 122 intersects the upper wall 135 of the displacement groove 133 in the two-dimensional space of X and Y.

[0100] refer to Figure 8B The upper surface 122 and the wedge-shaped groove 141 do not intersect in the three-dimensional space of X, Y, and Z.

[0101] However, from Figure 8B It can be concluded that the upper surface 122 intersects the wedge-shaped groove 141 in the two-dimensional space of X and Y.

[0102] refer to Figure 5B The upper surface 122 and the wedge groove 141 do not intersect in the two-dimensional space of the XZ plane. Therefore, the wedge groove 141 can be formed without cutting off the outermost part of the upper surface 122 at the corner C, or alternatively, the outermost part of the upper surface 122 that overlaps with the wedge groove 141 in the XY plane can be formed.

[0103] The upper wall 135 and the upper surface 122 of the locking tenon 121 can intersect or cross in two-dimensional space X and Y, but cannot intersect or cross in three-dimensional space X, Y and Z.

[0104] The wedge-shaped groove 141 and the upper surface 122 of the locking tongue 121 can intersect or cross in two-dimensional space X and Y, but cannot intersect or cross in three-dimensional space X, Y and Z.

[0105] The displacement groove 133 and preferably the wedge-shaped groove 141 can be configured such that when the adjacent upper surfaces 122 of the adjacent panels 1, 2 are substantially abutted when they are configured in the assembly position by means of the second mechanical locking system 60.

[0106] One advantage of the embodiments of this disclosure is that the engagement system along the long side, such as the first mechanical locking system 50, can be more resistant to the penetration of fluids such as water.

[0107] Refer again Figures 8A-8B The distance D3 between the upper surface 15 of the panel 1 and the upper outermost edge 142 of the wedge-shaped groove 141 can preferably be greater than the distance D1 between the upper surface 15 of the panel 1 and the upper surface 122 of the locking tongue 121. As a result, as... Figure 8BAs shown, the projection H1 of the upper surface 122 in the longitudinal direction L of the panel 1 may not intersect with the projection O2 of the wedge groove 141 in the transverse direction T of the panel at the corner C. The corner C may be the corner between the first locking system 50 of the second edge 12 and the second locking system 60 of the fourth edge 14. Thus, the upper surface 122 of the locking tongue 121 of the first mechanical locking system 50 (which may be located on the long side of the panel) will not be cut off by one or more cutting tools (not shown) configured to form a displacement groove 133 of the second mechanical locking system 60 (which may be located on the short side of the panel adjacent to the long side).

[0108] Distance D1 can be a distance measured between the plane of the upper surface 15 and the upper surface 121 and / or the first locking surface 122a, such as the shortest distance or a distance perpendicular to the upper surface 15.

[0109] The distance D2 can be the shortest measured distance between the upper surface 15 and the upper wall 135 of the displacement groove 133, perpendicular to the upper surface 15. In this exemplary embodiment, D2 can be measured perpendicular to the upper surface 15 between the outermost edge of the upper surface 15 and the outermost edge of the upper wall 135, which together with the outermost edge of the lower wall 134 forms the opening 137 of the displacement groove 133.

[0110] One effect of having a greater distance D2 than distance D1 is that the displacement groove 133 can be formed completely below the plane of the upper surface 122 of the locking tongue 121, and / or completely below the plane of the first locking surface 122a of the locking tongue 121 of the first locking system 50, for example at the corner / intersection point B between the second edge 12 and the third edge 13.

[0111] Reference Figure 9A In the assembly position of adjacent panels, the closely juxtaposed upper edge portions 118, 128 of the first edge 11 of panel 1 and the second edge 12 of the substantially identical adjacent panel 2 can form a first vertical plane VP1.

[0112] The first locking strip 112 protrudes from the first edge 11 and the first vertical plane VP1 and includes a first locking element 113 configured to be received in a first locking groove 124 of the second edge 12 of the adjacent panel by folding displacement for horizontal locking of the adjacent panel by the first mechanical locking system 50.

[0113] Reference Figure 9B In the assembly position of adjacent panels, the upper edge portions 138, 148 of the closely juxtaposed third edge 13 of panel 1 and the fourth edge 14 of adjacent substantially identical panel 2 can form a second vertical plane VP2.

[0114] The second locking strip 139a protrudes from the second vertical plane VP2 and includes a second locking element 139b configured to be received in the second locking groove 145 of the fourth edge 14 of the adjacent panel by vertical displacement of the adjacent panel 2, such as vertical folding, for horizontal locking of the adjacent panel by the second mechanical locking system 60.

[0115] The upper surface 122 of the locking tongue 121 can extend along the length direction L of the panel to the upper edge portion 138 forming the vertical plane VP.

[0116] Now for reference Figures 10A-10B ,in Figure 10A The first mechanical locking system 50 of panel 1 is shown again. Figure 10B The second mechanical locking system 60 of panel 1 is shown again. Figure 10A Implementation examples may include Figure 9A All features of the embodiments, Figure 10B Implementation examples may include Figure 9B All features of the embodiments shown are illustrated, however, some reference numerals have been omitted for clarity.

[0117] Panel 1 may include a plane S that extends parallel to the front surface 15 and / or rear surface 16 of panel 1. Plane S may be a horizontal H-plane.

[0118] In one aspect, the upper surface 122 of the locking tongue 121 may be provided on a first side S1 of the plane S, and the displacement groove 133 and preferably the wedge-shaped groove 141 are provided on a second side S2 of the plane S, wherein the second side S2 is the opposite side of the first side S1.

[0119] Preferably, the entire upper surface 122 of the locking tongue 121 can be provided on the first side S1 of the plane S, and the entire displacement groove 133 and preferably the entire wedge groove 141 are provided on the second side S2 of the plane S.

[0120] A first side S1 of plane S may extend from plane S toward and / or face the front surface 15 of panel 1. The first side S1 may include the upper portion of panel 1. A second side S2 of plane S may extend from plane S toward and / or face the rear surface 16 of panel 1. The second side S2 may include the lower portion of panel 1.
