A device for connecting two furniture parts, wherein the device comprises a housing arrangeable on a first furniture part and an eccentric element rotatably mounted in the housing. The housing is on one wall side flattened, and the flattened wall side of the housing has a continuous opening. The eccentric element is configured to cooperate with a connecting element, wherein the connecting element is arrangeable on a second furniture part, and wherein the connecting element can be coupled with the housing and the eccentric element such that the first and the second furniture part are fixedly connected to each other. The device is characterized in that the continuous opening in the housing on the flattened wall side is fully enclosed at the margin by wall portions.

A connecting expansion bolt over-molded with an expansion sleeve includes a bolt head at one bolt end and a bolt cone tapering in the direction of the bolt head. At the other bolt end, the bolt cone and an adjoining bolt shaft portion are over-molded with a plastic expansion sleeve, the sleeve end of which that surrounds the bolt cone is divided into a plurality of spreadable sleeve segments by open-ended slits. Provision is made for the sleeve end that surrounds the bolt cone to be divided into at least three sleeve segments. For at least two of the slits on the bolt cone that separate the sleeve segments from one another do not extend parallel to the bolt axis.

A joining device between components of an item of furniture, including a casing having a first and a second radially expandable portion for engaging the components of the item of furniture, a tie-rod housed inside the casing and axially slidable, and a cam element housed in said casing for axially displacing the tie-rod from the rest position to the locking position and vice-versa. According to the present invention, the cam element has a lobe along its outer periphery which has a forward profile having a predefined extension about the axis of rotation such as to perform, alone, the displacement of the tie-rod with respect to the casing from the rest position to the locking position so as to actuate the expansion of both portions with a single movement according to a forward rotation direction of the cam element and any return through a movement according to a return rotation direction.

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 fastening element (20) is provided for use with a tightening element (14) in a device for forming a joint between two panels (18,22). The fastening element is elongate and has a head (13) at one end for engaging the tightening element, an expander (15) at the other end and a shank (11) extending there between. The fastening element further comprises a sleeve (10) having an expandable section (16) at one end extending over the expander, with the expander operatively engaging the sleeve to cause outward movement of its expandable section upon axial displacement of the fastening element relative to the sleeve. The sleeve is provided with at least one outwardly facing cutting edge (19) on its expandable section. The cutting edge has sufficient strength to cut into the panel material in use of the device, when the expandable section is inserted into a face hole in a first one of the panels.

A tension connector connecting two components includes a bolt which has a bolt shaft and a bolt head. An eccentric lever has a bearing pot with a pot opening and with a pot interior which is formed as a pivoting bearing and by means of which the eccentric lever can be or is mounted on the bolt head so as to be pivotable about a pivot axis between a starting position and a tensioned position. The bearing pot has a slot for the bolt shaft, extending from the pot opening against the tensioning direction and, along the slot, has an outer contour which is eccentric relative to the pivot axis.

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 barrel for a barrel joint for parts of furniture and furnishing items includes a hollow cylindrical body containing a blocking element and having at least one hole on one of its side surfaces for the passage of a tip of a tool that actuates the blocking element, the hollow cylindrical body also having at least another hole for receiving a pin of the barrel joint.

An assembly/joining device (10) for parts or components of modular furniture and furnishing accessories of the shelf units, bookcases, cupboards, bed frames type and the like, including a pin (12) and a bushing (14) inserted in dedicated seats made in the components of the furniture to be joined and attached rigidly one with respect to the other, the pin (12) which includes a ferrule (24) elastically retractable internally to the pin apt to couple with the bushing (14) and co-operating with guide elements of the bushing (14) for a coupling/uncoupling between the pin (12) and bushing (14) during assembly/disassembly of the furniture parts.

An aluminum cabinet is revealed. A plurality of positioning members is disposed on an upper edge, a lower edge and a middle part of an inner surface of two side plates. Two outer main plates are set between the two side plates respectively. An assembly block arranged at each of two sides of the outer main plate is mounted with an assembly member. The assembly member is mounted with and connected to the positioning member. An inner partition is arranged between the two side plates. A fixing block disposed on each of two sides of the inner partition is mounted with a fixing member. A fixing pin mounted in the fixing member is mounted with and connected to the positioning member. Thereby the connecting components are hidden after assembling. Thus not only the visual appearance of the cabinet is more pleasing, the sense of value is also increased.
