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

A piece of furniture, comprising a first and a 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.

A furniture panel is provided, in which a first element and a second element are mechanically locked together. A first tongue is provided at a first edge of the first element, the first tongue cooperating with a first tongue groove provided at a second edge of the second element for locking the first and second elements in a vertical direction, and a second tongue at the second edge of the second element, the second tongue cooperating with a second tongue groove at the first edge of the first element for locking the first and second elements in the vertical direction. A first pair of locking surfaces is provided above the second tongue and the second tongue groove for locking in a horizontal direction, and a second pair of locking surfaces is provided below the first tongue and the first tongue groove for locking in the horizontal direction.

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 groove at the first edge, wherein an edge tongue of the second edge is insertable into the edge 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. The first and the second panels are locked at a junction plane which is extending between the first main plane and the second main plane. The first edge comprises an edge tongue that extends from the junction plane.

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.

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 include a mechanical locking device which is configured for locking a first edge of the first panel to a second edge of the second panel at a junction plane. 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 mechanical locking device includes at the first edge an edge tongue which extends from the junction plane and at the second edge includes an edge groove at the junction plane. The mechanical locking device includes a dowel at the first edge and a dowel groove at the second edge. The dowel is configured to cooperate with the dowel groove.

An assembled product includes at least three elements arranged in three different planes. A first element is connected perpendicular to a second element, and a third element is connected perpendicular to the second element. The assembled product includes one or more locking devices, each comprising a flexible tongue arranged in an insertion groove one of the at least three elements. The flexible tongue cooperates with a tongue groove, at an adjacent one of the at least three elements, for locking the one element and the adjacent element together. A second edge of the second element is connected to a second edge of the third element by a first of said locking devices.

Composed element including at least two panel-shaped elements, which each have an edge zone in which coupling means are present in the form of a profiled part respectively extending in the longitudinal direction of the respective edge zone, as well as each including an end face extending transversely to the respective edge zone, wherein said profiled parts allow coupling the panel-shaped elements together in an interlocking manner, wherein 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.

A system for fastening a first wooden member to a second wooden member includes a tenon configured to couple to the first wooden member such that the tenon extends from the first wooden member. The tenon has a first hole, a second hole, and a third hole. A first fastener extends through the first hole of the tenon and secures the tenon to the first wooden member. A second fastener extends through the second hole of the tenon and secures the tenon to the first wooden member. A third fastener extends through the second wooden member and is received into the third hole of the tenon to thereby secure the first wooden member to the second wooden member. The third fastener can be removed to thereby disconnect the first wooden member from the second wooden member repeatedly without aesthetic damage or loss of structural integrity.
