DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS OF THE INVENTION

[0037] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness. Like reference character refer to like elements throughout the description.

[0038] With reference to FIG. 1A, a cabinet 1 comprises two side panels 2, 3, a top panel 4, a bottom panel 5, and a back panel 6. The cabinet 1 further comprises a rectangular front face frame 7, wherein a side 8 of the front face frame 7 is facing a front facing edge 9 of each of the two side panels 2, 3, top panel 4, and bottom panel 5. Each front facing edge 9 comprises an integrally formed and elongate protruding section 11. In this embodiment, each front facing edge 9 comprises a protruding section 11 that is formed in one piece with the respective panel. The rectangular front face frame 7 comprises elongate grooves 10, see FIGS. 2A and 2B, wherein each groove 10 is configured for mechanical locking with one of the elongate protruding sections 11. Each of the elongate grooves 10 comprises a longitudinal recess 12, see FIG. 3A, on a side of each groove 10 for receiving a flexible locking element 13. Each of the protruding sections 11 comprises a longitudinal insertion recess 14 for holding a flexible locking element 13, see FIG. 3A.

[0039] The protruding section 11 may be formed in one piece with one of the two side panels 2, 3, the top panel 4, and the bottom panel 5, respectively. The protruding section may be the entire front facing edge or may be a portion of the front facing edge. The longitudinal insertion recess may extend along the entire front facing edge, or at least effectively extend along the entire front facing edge excepting where there is an elongate groove for receiving a top panel or a bottom panel. The longitudinal insertion recess may extend along only a portion of the front facing edge. For example, the longitudinal insertion recess may have longitudinal ends which do not extend to longitudinal ends of the front facing edge.

[0040] The protruding section 11 may be formed by mechanical cutting, such as milling.

[0041] The side panels 2, 3, the top panel 4, the bottom panel 5, the back panel 6, and the rectangular front face frame 7 may comprise wood based materials, such as particle boards, plywood boards, HDF-boards, MDF-boards, and solid wood.

[0042] The flexible locking element 13 may comprise a polymer material, such as a thermoplastic or a thermosetting plastic.

[0043] The flexible locking element 13 may be an injection moulded or extruded component which may comprise a polymer material, such as a thermoplastic.

[0044] As also can be seen the back panel 6 may be arranged for mechanical locking with the two side panels 2, 3, top panel 4, and bottom panel 5. The side edges of the back panel 6 have elongate protruding sections 11 for said mechanical locking with corresponding elongate grooves 10 of the two side panels 2, 3.

[0045] The back edges of the top panel 4 and the bottom panel 5 may have elongate protruding sections 11 for said mechanical locking with corresponding elongate grooves 10 of the back panel 6.

[0046] In an embodiment, the side panels may include one edge, a front facing edge, with a protruding section and three edges, a top edge, a bottom edge, and a back edge, each with an elongate groove. The top panel and bottom panel may each have four edges, each edge with a protruding section. The front face frame may have four edges, each with an elongate groove. The back panel may include top and bottom edges, each with an elongate groove, and side edges, each with a protruding section.

[0047] FIG. 3B is a side view of the panel 2, 3 shown in FIG. 3A, and an enlarged portion of FIG. 3B is shown in FIG. 3C.

[0048] Moving on to FIG. 4A, two panels are connected such that the protruding part 11 of a panel 4, 5 is inserted in a groove 10 of the other panel 2, 3. As shown in FIG. 4B, which is enlarged portion from FIG. 4A, the longitudinal recess 12 is located closest to the edge of the panel 2, 3. The left side of the vertically arranged panel 4, 5 is flat which means that any variations in the thickness of the horizontally arranged panel 2, 3, should not create a gap between the panels that is visible from the inside of the cabinet.

[0049] In an embodiment, all connections of a protrusion part and a groove in a cabinet are arranged such that the longitudinal recesses face away from the inside of the cabinet. This reduces gaps between the panels that may be visible from inside the cabinet.

[0050] Further, the upper and lower grooves of the side panels 2, 3, the back panel 6, and the front face frame 7 may be at an edge distance 41 from their respective edges 43. The top panel 4 and/or the bottom panel 5 may have a panel thickness 42. The edge distance may be in the range of 0.2 to 5 times the panel thickness 42, such as 0.3 to 4 times the panel thickness 42, such as 0.4 to 3 times the panel thickness 42, such as 0.5 to 2 times the panel thickness 42. The edge distance may be measured from an outer groove surface to an outer edge surface 43.

[0051] The longitudinal recesses 12 of the upper and lower grooves 10 in the side panels 2, 3 may be located on the side of the grooves 10 closest to their respective edges. Also, the longitudinal recesses 12 of the upper and lower grooves 10 in the back panel 6 may be located on the side of the grooves 10 closest to their respective edges, the principle shown in FIG. 3C.

[0052] The longitudinal recesses 12 of the upper and lower grooves 10 in the front face frame 7 may be located on the side of the grooves 10 closest to their respective edges.

[0053] As can be seen in FIGS. 5A and 5B, an embodiment is shown where a protruding part 11 has an elongate indent on one side of the panel with a longitudinal beveled surface 15 between the indent and the panel side. In addition, the corresponding groove 10 may have, at one side, an elongate beveled surface 16 generally corresponding, such as within 5?, to the longitudinal beveled surface of the panel with the protruding part 11. As also can be seen, the longitudinal recess 12 of the groove may be on the same side of the groove as the beveled surface 16.

[0054] FIG. 6A shows in a cross-cut view an embodiment of the flexible locking element 13 arranged in an embodiment of the longitudinal insertion recess 14.

[0055] FIG. 6B shows in a cross-cut view that an embodiment of the flexible locking element 13 may be compressed in a direction 32 toward a bottom surface 31 of an embodiment of the longitudinal insertion recess 14. The flexible locking element 13 may be compressed to a compressed state in which essentially the whole flexible locking element is within the longitudinal insertion recess 14. The compressed state may facilitate an assembling of the panels.

[0056] FIG. 6C shows, in a 3D-view, an embodiment of the flexible locking element 13. The flexible locking element 13 may comprise a bendable portion 34, such as a first bendable portion and a second bendable portion. The flexible tongue 33 may comprise a recess 36 at each of said bendable portions 34. An advantage with this embodiment of the flexible tongue is that a stronger spring force may be obtained which may provide a stronger locking.

[0057] The flexible locking element 13 may comprise an outer edge, with a beveled or rounded shape.

[0058] The flexible locking element 13 may comprise a protruding friction element 107 on the first and/or second bendable portion 34.

[0059] FIG. 6D shows in a cross-cut view an enlarged end part of an embodiment of the side panels 2,3.

[0060] FIG. 6E shows in a cross-cut view an enlarged end part of an embodiment of the top panel 4 or the bottom panel 5.

[0061] FIG. 6F shows in a cross-cut view the enlarged end part of the embodiment of the side panels 2, 3 shown in FIG. 6D connected to the enlarged end part of an embodiment of the top panel 4 or the bottom panel 5 shown in FIG. 6E.
