A composed element, such as a piece of furniture, wherein the composed element comprises at least a rear wall, as well as a number of constructional parts forming a whole in which the rear wall has to be provided. The rear wall forms the rear side of the composed element and includes one or more rear wall parts. The composed element comprises seats for installing at least one of the rear wall parts, which are configured such that the rear wall part can be slid into the seats starting from the rear side of the composed element from a position differing from the final plane in which the rear wall part will be situated in the final condition.

In as first aspect of the invention, this is achieved by a joining system for furniture parts comprising female coupling recess formed in a first furniture part, a male coupling tongue projecting from an adjoining second furniture part, said female coupling recess being adapted to receive the male coupling tongue, said male coupling tongue comprising a first locking element configured for a snap joint interlocking engagement with a matching second locking element in said female coupling recess, the male coupling tongue being configured to be more flexible than the female coupling recess. The joining system comprises an upper guiding surface arranged on a first side of the female coupling recess on the first furniture part, forming an essentially non-resilient guide for the male coupling tongue upon insertion thereof, limiting movement of said male coupling tongue in a direction towards said first side of the female coupling recess. The joining system comprises a lower guiding surface arranged on a second side of the female coupling recess on the first furniture part, located opposite to said first side thereof, said lower guiding surface is configured to force the male coupling tongue to resiliently deflect whilst in engagement with said upper guiding surface upon further insertion thereof in a deflection movement towards said first side of the female coupling recess, until the first locking element of the male coupling tongue snaps together with the matching second locking element of the female coupling recess.

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.

An assembled product, such as an assembled product, such as a furniture component or a furniture, such as a drawer, a cupboard, bookshelves, a wardrobe, a kitchen fixture, or a box for storing or transporting including at least three panels arranged in three different planes. Also, a set of panels for an assembled product and a method of assembling the product.

A piece of furniture, comprising a first and second furniture part, which are coupled to each other at an angle by means of mechanical coupling means. A female part is made as an oblong slot in the second furniture part with an insertion opening for introducing a male part. When coupling the first furniture part and the second furniture part to each other, the male part is brought from an insertion position in the insertion opening to an end position in the female part by moving the male part and the female part along each other. The male part is situated on a narrow end of the first furniture part and is positioned with its center line between the central plane of the first furniture part and the inner side of the first furniture part. The slot is realized in the inwardly directed flat side of the second furniture part.

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).
