A modular shelving unit includes a plurality of shelves supported by supports. Non-linear attachment pins are attached to the top of a lower shelf and received in upper supports which support an upper shelf. The attachment pins are bent so that they are wider than holes in the upper supports; bending the attachment pins elastically and maintaining them elastically bent when the shelving unit is in an assembled state.

A modular furniture piece with integrated connectors comprises a first module with a plurality of first integrated connectors selectively located thereon. A second module is provided for fastening to the first module, and the second module has a plurality of second integrated connectors located thereon. The first integrated connectors register with the second integrated connectors when the first module and the second module are positioned with respect to each other in their assembled orientation.

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 kit is provided that, when assembled, forms a unit of furniture. The kit includes side panels that can reversibly slide into an opening formed in the sides of the front and side panels. The kit may include multiple locking pins to restrict movement of the top and side panels. The kit may include positioning wedges and/or locking wedges to restrict relative movement of the panels and thus improve the stability of the unit. Also provided are methods of assembling the unit of furniture.

A modular shelving unit includes a plurality of shelves supported by supports. Non-linear attachment pins are attached to the top of a lower shelf and received in upper supports which support an upper shelf. The attachment pins are bent so that they are wider than holes in the upper supports; bending the attachment pins elastically and maintaining them elastically bent when the shelving unit is in an assembled state.

In a 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.

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, 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 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.
