A joining device for parts of furniture and furnishing accessories, of the shelf unit, bookcase, drawer unit, bed frame, seating type and the like, includes a casing or container body suitable for being inserted in a seat formed in one of the components of the item of furniture to be joined and is provided with an expansion bushing externally projecting with respect to a first end or front open end of said casing or container body and suitable for engaging with a further seat of a further component of the item of furniture to be joined to the component wherein the casing or container body is inserted. Said joining device includes a cam mechanism for a linear motion of actuation means co-operating in an expansion deformation movement of the expansion bushing and simultaneous expansion of at least one portion of said casing or container body.

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.

A connecting device is provided including one or more connecting elements arranged on at least one connectable part. At least one connecting element includes non-self-cutting retaining projections having a curved supporting surface in the form of an arc of a circle in longitudinal section. A groove is provided in one of the connectable parts, the groove having a curved undercut surface in the form of an arc of a circle in longitudinal section and including a base section and two undercut sections which extend away from the base section in a thickness direction. The retaining projections are engageable with the undercut sections of the groove. One or more connecting elements include or are in the form of one or more screw elements, and one or more connecting elements include one or more moveable retaining elements by means of which the parts can be drawn towards and/or pressed against each other.

A tool-less fastening system includes an interface assembly including an interface body having a first longitudinal end, a second longitudinal end, and a contact surface disposed between the first longitudinal surface and the second longitudinal surface, a fastening element coupled to the interface body, and a stop block extending from the interface body at the second longitudinal end, the stop block including an inclined surface. The tool-less fastening system also includes a receiver shaped to receive the interface body. The receiver has a receiver body defining a channel and at least one receiver block extending from the receiver body into the channel, wherein the at least one receiver block includes a receiving surface for receiving the contact surface of the interface body. In some embodiments, the tool-less fastening system can be implemented with shippable furniture, such as office chairs and tables.

A connecting device is provided including one or more connecting elements arranged on at least one connectable part. At least one connecting element includes non-self-cutting retaining projections having a curved supporting surface in the form of an arc of a circle in longitudinal section. A groove is provided in one of the connectable parts, the groove having a curved undercut surface in the form of an arc of a circle in longitudinal section and including a base section and two undercut sections which extend away from the base section in a thickness direction. The retaining projections are engageable with the undercut sections of the groove. One or more connecting elements include or are in the form of one or more screw elements, and one or more connecting elements include one or more moveable retaining elements by means of which the parts can be drawn towards and/or pressed against each other.

A joining device for parts of furniture and furnishing accessories includes a casing or container body suitable for being inserted in a seat formed in one of the components of the item of furniture to be joined. An expansion bushing externally projects with respect to a first end or front end of said casing or container body and is suitable for engaging with a further seat of a further component of the item of furniture to be joined to the component wherein the casing or container body is inserted. Said joining device includes a cam mechanism for a linear motion of actuation means co-operating in an expansion and retraction deformation movement of the expansion bushing and simultaneous expansion of at least one portion of said casing or container body, with said cam mechanism and actuation means housed in the casing or container body and actuated by a tool.

A connecting device having a hollow-body-like plug-in part which is of variable outer circumference and which interacts with a fixing device which is at least partially insertable into the plug-in part, wherein the fixing device is connectable to an actuation section which projects out of the plug-in part. Here, the plug-in part, with the fixing device inserted therein and with the actuation section connected thereto, has the minimum external shape thereof in terms of the dimensions thereof when the actuation section is in a rest position. The actuation section is moved by means of axial or radial movement relative to the plug-in part into a working position in which the plug-in part has the maximum external shape thereof in terms of the dimensions thereof, wherein the plug-in part has a closed shape on its side situated opposite the insertion side of the fixing device.

A connector for insertion into two connectable items consists of two parts with inter-engaging features, for instance, a spigot and socket, which may be latched together under the force applied by a pivoting latch arm in one part with a tensionable clamping arm engaging the other part to clamp the two parts together when the latch arm is homed.

A method, a locking device and a set of panels, including a panel and an adjacent panel, wherein the panel includes a groove and at least one hole connected to the groove via an opening, the adjacent panel includes a first edge that is configured to be arranged in the groove of the panel, and the panel includes a locking device configured to lock the first edge of the adjacent panel in the groove of the panel, wherein the locking device includes a cylinder and a lever connected to the cylinder, the cylinder is configured to be arranged in the hole in the panel, the cylinder is an eccentric cylinder including a top and bottom base and a locking surface connecting the top and bottom base, the cylinder is configured to act as a cam when the cylinder is turned about an axis in the hole.

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.
