[0057] Embodiments of the present invention are as follows Figure 1-16 The diagram illustrates an assembly including a first panel 10, a second panel 20, and a mechanical locking device for locking the first panel 10 to the second panel 20. The first panel 10 includes a first edge surface 11 and a first panel surface 13. The second panel 20 includes a second panel surface 22. In the locked position of the first and second panels 10, 20, the first edge surface 11 faces or is parallel to the second panel surface 22. The mechanical locking device includes at least one element 31 at the first edge surface 11 and at least one insertion recess 32 at the second panel surface 22. The element 31 may be rod-shaped. The rod-shaped element 31 is configured to insert into the insertion recess 32. The rod-shaped element 31 extends from the first edge surface 11 at a first angle α1, and the insertion recess 32 extends from the second panel surface 22 into the second panel surface 22 at a second angle α2. When more than one rod-shaped element 31 is present, each rod-shaped element 31 may be arranged parallel to the other rod-shaped elements 31. When more than one insertion recess 32 exists, each insertion recess 32 may be arranged parallel to the other insertion recesses 32.

The locking member 34 is configured to be inserted into the locking groove 35 and abut against the locking surface 37 for locking, and the third angle β is different from the first angle α1.

[0058] The first panel 10 and the second panel 20 can be panels used for furniture products, and can be part of the furniture product frame.

[0059] The component can be configured to lock the first panel 10 to the second panel 20, wherein the surface of the first panel 13 is perpendicular to or substantially perpendicular to the surface of the second panel 22.

[0060] The second panel 20 may include a fourth edge surface 25, and the insertion recess 32 may be positioned adjacent to the fourth edge surface 25. The assembly may be configured to lock the first panel 10 to the second panel 20, wherein the first panel surface 13 is parallel to or substantially parallel to the fourth edge surface 25.

[0061] Figure 1-3 , Figure 5A , Figure 7-8 , Figure 11 and Figure 16 The components in an unassembled state, according to one aspect, are disclosed. Figure 4 , Figure 6 , Figure 9-10 and Figure 12-14 An assembled component is disclosed according to one aspect. The component can be assembled by displacement of the first panel 10 relative to the second panel 20 in assembly directions 111, 112, 114 substantially parallel to the surface 13 of the first panel. A mechanical locking device can be configured to automatically lock the first panel 10 onto the second panel 20 when the rod-shaped element 31 is inserted into the insertion groove 32 and the locking member 34 is inserted into the locking slot 35 and abuts against the locking surface 37. The component can be locked when the first edge surface 11 abuts against the surface 22 of the second panel.

[0062] The third angle β can be approximately 45° to approximately 90° larger than the first angle α1 and / or the second angle α2.

[0063] The locking component 34 can be positioned on the first edge surface 11 or the second panel surface 22, and the locking groove 35 can be positioned on the opposite second panel surface 22 or the first edge surface 11.

[0064] The first angle α1 and / or the second angle α2 may be in the range of approximately 30° to 60°, or approximately 40° to 50°, or approximately 45°. The first angle α1 and the second angle α2 may be parallel or substantially parallel.

[0065] Assembly directions 111, 112, and 114 can be substantially parallel to the first angle α1 and / or the second angle α2.

[0066] The third angle β of the locking surface 37 can be in the range of approximately 70° to 110°, or in the range of approximately 80° to 100°, or in the range of approximately 85° to 95°, or approximately 90°.

[0067] The locking component 34 can be flexible.

[0068] The locking member 34 can be configured to be partially located in the locking groove 35 in an unbent / uncompressed state.

[0069] The locking component 34 may include a spring.

[0070] The locking component 34 may be arranged in a locking component groove 38 located on the first edge surface 11 or on the second panel surface 22.

[0071] The locking member 34 can be configured to be substantially located in the locking member recess 38 in the flexed / compressed state.

[0072] When the first panel 10 and the second panel 20 are assembled together, the locking member 34 can be compressed and is substantially located in the locking member recess 38. The locking member 34 may include a spring that facilitates the compression of the locking member 34. As the first panel 10 moves relative to the second panel 20 in the assembly direction, the rod-shaped element 31 is inserted into the insertion recess 32. When the locking member 34 encounters the locking slot 35, the locking member 34 can extend outward from the locking member slot 38 and protrude into the locking slot 35. The first panel 10 and the second panel 20 will then be locked together because the positioning of a portion of the locking member 34 in the locking slot 35 prevents the first panel 10 from moving relative to the second panel 20 in a direction opposite to the assembly direction.

[0073] The insertion groove 32 and / or locking groove 35 can be a drilled hole. The drilled hole can be a drilled hole with a bottom end.

[0074] The insertion groove 32 may have a diameter D2.

[0075] like Figure 8 As shown, the insertion recess 32 may include a chamfer or fillet 60, which is configured to guide the rod-shaped element during assembly.

[0076] The rod-shaped element 31 can be arranged on the first edge surface 11 of the first panel 10 or in the rod-shaped element groove 36 on the second panel surface 22 of the second panel 20.

[0077] The rod-shaped element 31 may have a diameter D1. The diameter D2 of the insertion groove 32 may be larger than the diameter D1 of the rod-shaped element 31. For optimal assembly, the diameter D2 of the insertion groove 32 may be approximately 0.3 to approximately 0.8 mm larger than the diameter D1 of the rod-shaped element 31.

[0078] According to one aspect, the component may include a first panel groove 12 on a first panel surface 13 of a first panel 10 and / or a second panel groove 23 on a second panel surface 22 of a second panel 20.

[0079] The first panel groove 12 on the first panel surface 13 may have a width W1.

[0080] The second panel groove 23 on the second panel surface 22 may have a width W2.

[0081] The width W1 of the first panel groove 12 can be substantially the same as the width W2 of the second panel groove 23.

[0082] The component may also include a back panel 40. The back panel 40 may be configured to insert into and optionally cooperate with the first panel groove 12 and the second panel groove 23.

[0083] Figure 6 It is shown that the back panel 40 can be assembled to the first panel 10 and the second panel 20 by moving the back panel 40 relative to the first panel 10 and the second panel 20 in an assembly direction 113 that is substantially perpendicular to the second panel surface 22 of the second panel 20. The thickness T of the back panel 40 may be substantially the same as the width W1 of the first panel groove 12 and / or the width W2 of the second panel groove 23.

[0084] A gap may exist between the back panel 40 and the first panel groove 12 and / or the second panel groove 23, which may facilitate displacement of the edge of the back panel 40 within the first panel groove 12 and / or the second panel groove 23. The gap may be in the range of approximately 0 mm to approximately 0.5 mm, or in the range of approximately 0.1 mm to approximately 0.2 mm.

[0085] In one aspect, the difference between the width W1 of the first panel groove 12 and / or the width W2 of the second panel groove 23 and the thickness T of the back panel 40—that is, ΔW—is equal to or greater than the extension length H of the back panel 40 relative to the first panel 10 or the second panel 20 after the first panel 10, the second panel 20, and the back panel 40 are assembled, i.e., ΔW ≥ H, see Figures 12-15 .

[0086] Figure 13 An embodiment including a positioning element 50 is shown for positioning the back panel 40 relative to the first panel groove 12 and / or the second panel groove 23. The positioning element 50 may include a first wedge element 51 and a second wedge element 52.

[0087] In one respect, H is less than the extension length D of the rod-shaped element 31 from the first edge surface 11.

[0088] The rod-shaped element 31 may have an extension length E along the first edge surface 11.

[0089] In one aspect, if an assembly comprising two first panels 10 and two second panels 20 is to be assembled, at least one panel 10, 20 may have a first panel groove 12 of width W1 and / or a second panel groove 23 of width W2, the width of which allows the extension H of the back panel 40 to be displaced within the first panel groove 12 and / or the second panel groove 23. The displacement may be equal to or greater than ΔW. In another aspect, all panels 10, 20 have the same first panel groove 12 width W1 and second panel groove 23 width W2 to facilitate panel production.

[0090] The length of the back panel 40 can be designed to avoid an extension H of the back panel 40. The edge of the back panel 40 can be substantially flush with the surface of the first edge 11 of the first panel 10.

[0091] Figure 15 A side view of an embodiment of a first panel 10 having a first panel groove 12 is shown. The first panel groove 12 may have a width W1 and a height H1. The first panel 10 may include a second edge surface 14, and the second panel 20 may include a third edge surface 24. The first panel groove 12 may be substantially parallel to the second edge surface 14, and the second panel groove 23 may be substantially parallel to the third edge surface 24.

[0092] The first panel groove 12 may extend substantially along the entire second edge surface 14, and the second panel groove 23 may extend substantially along the entire third edge surface 24.

[0093] The first panel groove 12 and / or the second panel groove 23 may have a bottom.

[0094] The first panel groove 12 and / or the second panel groove 23 may be formed by mechanical cutting, such as milling or sawing.

[0095] The first panel groove 12 can be formed in the first panel surface 13 and in the core of the first panel 10. The second panel groove 23 can be formed in the second panel surface 22 and in the core of the second panel 20.

[0096] The first edge surface 11 may include two or more of the said rod-shaped elements 31, and the second panel surface 22 may include two or more of the said insertion grooves 32, or vice versa, which may be arranged in a straight line, wherein each rod-shaped element 31 is configured to be inserted into an insertion groove 32.

[0097] Locking the first panel 10 onto the second panel 20 in a direction parallel to the second panel surface 22 can be achieved by inserting the locking member 34 into the locking slot 35 and abutting against the locking surface 37. The locking surface extends from the first edge surface 11 at a third angle β, wherein the third angle β is approximately 45° to approximately 90° larger than the first angle α1.

[0098] The cross-section of the insertion recess 32 in a plane parallel to the second panel surface 22 can have a shape that matches the cross-section of the rod-shaped element 31 in a plane parallel to the first edge surface 11. One advantage of doing so is that it enables an improved locking of the first panel 10 to the second panel 20, and the assembly of the panel assembly is easy to complete.

[0099] exist Figures 5A-8 and Figure 10 The rod-shaped element 31 and the insertion groove 32 are disclosed in more detail, showing a cross-section cut along the rod-shaped element 31 and the insertion groove 32.

[0108] According to another aspect, the first edge surface 11 may have a combination of at least one rod-shaped element 31 and at least one insertion groove 32. The corresponding second panel surface 22 may have a corresponding combination of at least one insertion groove 32 and at least one rod-shaped element 31.

[0109] according to Figure 8 In one aspect, at least one rod-shaped element 31 can be positioned at a first distance 83 from the second edge surface 14. This first distance can be measured from the centerline 81 of the second edge surface 14 to the rod-shaped element 31. A corresponding insertion groove 32 can be positioned at a second distance 84 from the third edge surface 24. This second distance can be measured from the centerline 82 of the third edge surface 24 to the insertion groove 32. The first distance can differ from the second distance, which can increase the locking force.

[0110] The difference between the first and second distances can be in the range of approximately 0.1 mm to approximately 0.5 mm.

[0111] According to one aspect, the rod-shaped element 31 is made of one or more of a wood-based material and a polymeric material, the polymeric material of which may include reinforcing materials such as glass fiber or metal.

[0112] According to one aspect, the rod-shaped element 31 may have a waxed surface to facilitate assembly.

[0113] According to one aspect, the rod-shaped element 31 can be configured to cooperate with the bottom surface of the insertion groove 32 in the locked position.

[0114] The sidewalls of the insertion groove 32 and the locking groove 35 may include the material of the core of the first panel 10 or the second panel 20, depending on which panel they are formed in. According to one aspect, they may also be reinforced using, for example, metal or glass fiber.

[0115] According to one aspect, the locking groove 35 can be impregnated / reinforced with liquid.

[0116] According to one aspect, such as Figure 5A , Figure 11 and Figure 16As shown, the first panel 10 and the second panel 20 can be assembled by displacement of the first panel 10 relative to the second panel 20 in an assembly direction substantially parallel to the first panel surface 13. According to one aspect, the mechanical locking device is configured to automatically lock the first panel 10 to the second panel 20 when, by the displacement of the first panel 10 relative to the second panel 20, the rod-shaped element 31 is inserted into the insertion groove 32 and the locking member 34 is inserted into the locking slot 35 and locks against the locking surface 37.
