A joining system for furniture is provided. The joining system comprises a first furniture element and a joining element. The joining element has a width between a first and a second surface in the area of the second engaging portion. An increase in the width causes a first engaging portion to press harder on a first stabilizing portion which causes a male coupling portion to bend in a direction towards the surface comprising the second stabilizing portion to compensate for the increased width.

A set comprising a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel is disclosed. The first panel includes a first edge surface and a first panel surface and the second panel includes a second edge surface and a second panel surface. The mechanical locking device includes an insertion groove at the first edge surface, wherein the insertion groove has a first displacement surface and an opposite second displacement surface, a bottom surface and a depth direction. The insertion groove includes a flexible tongue, and an edge tongue including a tongue groove, wherein the flexible tongue is configured to cooperate with the tongue groove for locking of the first panel to the second panel, and the first and the second displacement surface of the insertion groove are converging.

A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel. The first edge surface is facing the second panel surface in a locked position of the first and the second panel, the mechanical locking device includes a rod-shaped element at the first edge surface and an insertion groove at the second panel surface, the rod-shaped element is configured to be inserted into the insertion groove. A first locking groove at the first edge surface and a second locking groove at the second panel surface and a locking part, where the locking part is configured to be inserted into the first locking groove and the second locking groove. The locking part is configured to apply a locking force between the first and the second panel in an oblique direction in relation to the second panel surface.

Composed element, wherein this composed element comprises at least two panel-shaped elements, which substantially are formed from a board material; wherein said panel-shaped elements are interconnected at an angle by means of coupling devices including a tongue and a groove, which coupling devices substantially are made as profiled parts in the board material; and wherein said coupling devices also include locking elements, which, in coupled condition, prevent the moving apart of the tongue and groove. The panel-shaped elements are formed on the basis of board material in the form of particle board consisting of two or more layers, which in respect to the average fineness of the particles, show a different degree of fineness, namely a basic layer with coarser particles, more particularly chips, and at least one outer layer, or at least a more outward-situated layer, which is of a finer composition than the composition of the basic layer, in other words, with particles, chips, respectively, which on average are finer.

A composed element includes at least two panel-shaped elements, which each have an edge zone in which coupling means are present in a profiled part respectively extending in the longitudinal direction of the respective edge zone, and each including an end face extending transversely to the respective edge zone. The profiled parts allow the coupling of the panel-shaped elements together in an interlocking manner. At least one of the panel-shaped elements includes an arrangement which hides from view at least a portion of the profiled part formed at the pertaining edge zone at the location of the end face.

Panels are shown, which are provided with a mechanical locking system including a separate and flexible tongue allowing connection with a snap action. An outer edge part of the separate flexible tongue includes a guiding protrusion that facilitates easy disassembly of the panels and that is deformed during locking and/or unlocking.

A set of panels includes a first panel having a first main plane and a second panel having a second main plane. The panels are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel. The mechanical locking device includes an edge section groove at the first edge, wherein an edge section of the second edge is insertable into the edge section groove. A flexible tongue is arranged in an insertion groove provided in the edge section groove, and cooperates with a tongue groove provided at the edge section of the second panel. A first thickness of a core material between the edge section groove and the outermost surface of the first edge is greater than a minimum second thickness of a core material of the edge section of the second panel.

Furniture carcass formed from panels assembled edge to edge by means of a groove (21) and loose tongue (11) assembly, a first (10) and a second panel (20) being joined by the edge of the first panel (10) hearing against the inner side (20a) of the second panel (20). The first panel (10) comprises a loose tongue (11), and the second panel (20) comprises, along the edge of its inner side (20a), a recess (21), complementary in shape to that of the edge with the bearing surface (15), a longitudinal assembly groove (21), complementary in shape to that of the tongue (11), and, beyond the groove (21), a bearing surface (25), recessed relative to the plane of its inner side (20a), for receiving the edge tearing surface (15). The assembly groove (21) has a bottom surface (22) and a small bearing surface (24) joined by a truncated concave ridge (27) and the loose tongue (11) has a complementary truncated ridge (17).

A set of panels including a first panel with a first main plane and a second panel with a second main plane. The first and the second panel are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel at a junction plane, wherein the first main plane is essentially perpendicular to the second main plane and the junction plane is extending between the first main plane and the second main plane. The first edge includes an edge tongue that extends from the junction plane. The second edge includes an edge groove at the junction plane. The edge tongue is configured to cooperate with the edge groove for locking together the first and the second edges in a first direction which is perpendicular to the first main plane. The edge tongue includes a tongue groove.

In the present invention of a storage case, a space can be saved in the packing form.

The skeleton frame of the storage case includes a pair of left and right side frames, a connecting pipe connecting the front end portions of the side frames, and a back panel connecting the rear end portions of the side frames. Therefore, in the skeleton frame, the bottom wall of the case can be supported by the support portion of the side frame without providing the bottom plate that supports the entire bottom wall of the case. As a result, when the storage case is disassembled, it is not necessary to vertically stack the bottom plates that receive the entire bottom wall of the case from below, so that it is possible to save space in the packing form of the storage case.
