This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed in breadth and integrity. Like numbers refer to like elements throughout the specification.
Referring to fig. 1A, the cabinet 1 includes 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 frame 7, wherein one side 8 of the front frame 7 faces the front edges 9 of the two side panels 2, 3, the top panel 4 and the bottom panel 5, respectively. Each front edge 9 comprises an integrally formed elongate protruding section 11. In this embodiment, each front edge 9 comprises a protruding section 11 formed in one piece with the respective panel. The rectangular front frame 7 comprises elongated grooves 10, see fig. 2A and 2B, wherein each groove 10 is configured for mechanical locking with one of the elongated protruding sections 11. Each elongate channel 10 comprises a longitudinal recess 12 on one side of each channel 10, see fig. 3A, for receiving a flexible locking element 13. Each protruding section 11 comprises a longitudinal insertion recess 14 for holding a flexible locking element 13, see fig. 3A.
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 edge or may be a part of the front edge. The longitudinal insertion recess may extend along the entire front edge, or at least effectively along the entire front edge, except where there is an elongated channel for receiving the top or bottom panel. The longitudinal insertion recess may extend along only a portion of the front edge. For example, the longitudinal end of the longitudinal insertion recess may not extend to the longitudinal end of the front edge.
The protruding section 11 may be formed by mechanical cutting (e.g. milling).
The side panels 2, 3, top panel 4, bottom panel 5, back panel 6 and rectangular front frame 7 may consist of wood based materials such as particle board, plywood, HDF board, MDF board and solid wood.
The flexible locking element 13 may comprise a polymeric material, such as a thermoplastic or a thermosetting plastic.
The flexible locking element 13 may be an injection molded or extruded part, which may comprise a polymeric material, such as a thermoplastic.
It can also be seen that the back panel 6 can be arranged for mechanical locking with the two side panels 2, 3, the top panel 4 and the bottom panel 5. The side edges of the back panel 6 have elongated protruding sections 11 for said mechanical locking with corresponding elongated grooves 10 of the two side panels 2, 3.
The rear edges of the top and bottom panels 4, 5 may have elongated protruding sections 11 for mechanical locking with corresponding elongated grooves 10 of the back panel 6.
In one embodiment, the side panels may include one edge with protruding sections, i.e., a front edge, and three edges, i.e., a top edge, a bottom edge, and a back edge, each with an elongated channel. The top and bottom panels may each have four edges, each with protruding sections. The front frame may have four edges, each with an elongated channel. The back panel may include top and bottom edges each with an elongated channel, and side edges each with a protruding section.
Fig. 3B is a side view of the panels 2, 3 shown in fig. 3A, and fig. 3C shows a partial enlarged view of fig. 3B.
Turning to fig. 4A, the two panels are joined together such that the protruding section 11 of one panel 4, 5 is inserted into the groove 10 of the other panel 2, 3. As shown in fig. 4B (which is a partial enlarged view of fig. 4A), the longitudinal recess 12 is located closest to the edges of the panels 2, 3. The left side of the vertically arranged panels 4, 5 is flat, which means that any thickness variation of the horizontally arranged panels 2,3 does not create a gap between the panels that is visible from the inside of the cabinet.
In one embodiment, all connections of protruding sections and grooves in the cabinet are arranged such that the longitudinal recess faces away from the cabinet interior. This reduces the gap between the panels visible from the inside of the cabinet.
Furthermore, the upper and lower grooves of the side panels 2, 3, the back panel 6 and the front 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 0.2 to 5 times the panel thickness 42, e.g. 0.3 to 4 times the panel thickness 42, e.g. 0.4 to 3 times the panel thickness 42, e.g. 0.5 to 2 times the panel thickness 42. The edge distance may be measured from the outer groove surface to the outer edge surface 43.
The longitudinal recesses 12 of the upper and lower channels 10 in the side panels 2, 3 may be located on the side of the channel 10 closest to its respective edge. Likewise, the longitudinal recesses 12 of the upper and lower channels 10 in the back panel 6 may also be located on the side of the channel 10 closest to its respective edge, the principle of which is shown in fig. 3C.
The longitudinal recesses 12 of the upper and lower channels 10 in the front frame 7 may be located on the side of the channel 10 closest to its respective edge.
As shown in fig. 5A and 5B, an embodiment is shown in which the protruding section 11 has an elongated indentation in one side of the panel with a longitudinal bevel 15 between the indentation and the side of the panel. In addition, the corresponding groove 10 may have an elongated bevel 16 on one side, which bevel 16 generally corresponds to the longitudinal bevel of the panel with protruding section 11, for example within 5 °. It can also be seen that the longitudinal recess 12 of the groove can be on the same side of the groove as the chamfer 16.
Fig. 6A shows an embodiment of a flexible locking element 13 in a sectional view, which is arranged in an embodiment of a longitudinal insertion recess 14.
Fig. 6B shows in a sectional view that an embodiment of the flexible locking element 13 can be pressed in the direction 32 towards the bottom surface 31 of an embodiment of the longitudinal insertion recess 14. The flexible locking element 13 may be pressed into a compressed state, wherein substantially the entire flexible locking element is located within the longitudinal insertion recess 14. The compressed state may facilitate assembly of the panel.
Fig. 6C shows an embodiment of the flexible locking element 13 in a 3D view. 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 of this embodiment of the flexible tongue is that a larger spring force can be obtained, providing a stronger locking effect.
The flexible locking element 13 may comprise an outer edge having a chamfer or rounded shape.
The flexible locking element 13 may comprise protruding friction elements 107 on the first and/or second bendable portion 34.
Fig. 6D shows an enlarged end portion of one embodiment of the side panels 2, 3 in a cross-sectional view.
Fig. 6E shows an enlarged end portion of one embodiment of the top panel 4 or the bottom panel 5 in a cross-sectional view.
