A set of panels including a first panel, a second, and a locking device. The locking device includes an edge groove at the first edge and a tongue groove at the second edge. The edge groove includes a flexible tongue arranged in an insertion groove at a first side of the edge groove. The edge groove includes a first groove surface at a first side of the insertion groove and a second groove surface at a second side of the insertion groove. The second edge includes a first edge surface at a first side of the tongue groove and a second edge surface at a second side of the tongue groove. The locking device is configured to be unlocked by inserting a tool in the tongue groove. The first groove surface is arranged offset in a second direction relative to the second groove surface by a first distance.

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.

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.

A method and device for inserting a tongue in an insertion groove in a panel by a device, wherein the method includes: displacing a tongue guiding device in a first direction by displacing a puncher in the first direction, and displacing a tongue between a first part and a second part of the tongue guiding device and into an insertion groove in panel by further displacing the puncher.

Provided is an assemblable wood brick. A unit of wood brick is composed of five plates including a top plate, two opposite first lateral plates and two opposite second lateral plates. Dovetail tenons, dovetail sluts, sluts and protrusions are correspondingly defined on sides each of the five plates such that the five plates are securely and orthogonally connect to each other at their sides to form a brick unit having a space defined there-inside. In addition, blind hole(s) can be provided on the outer surface of each one of the five plates such that any two brick can stably connect to each other by a fixed member corresponding to and engaging into the holes. Several types of furniture and constructions can be formed by connecting suitable amount of the bricks. Further, blind holes can be defined on both top side and bottom side of the second lateral plates such that any two bricks can stably connect to each other by a fixed member corresponding to and engaging into the holes.

A hutch unit including a front panel, a back panel, and two laterally opposing sidewalls hingedly connected to the front panel. One or more shelf units are provided, each shelf unit including a front shelf edge hingedly connected to the front panel and a rear shelf edge hingedly connected to the back panel. The back panel includes opposing lateral back edges, and first and second back flaps are hingedly connected to the lateral back edges extending forward from the back panel. Each of the first and second back flaps is positioned in abutting relationship to a respective sidewall to define first and second overlapping sidewall portions along each sidewall. Vertical sliding connections join the back flaps to the sidewalls at the overlapping sidewall portions, wherein the vertical sliding connections guide the back panel in vertical displacement relative to the sidewalls.
