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.

A spreading connector for connecting two furniture parts, including a built-in pot having a pot bottom, the pot being pressable, pot bottom first, into a housing bore of a first of the furniture parts. The pot further has a hollow-cylindrical pot wall that has a wall opening and at least one spreading tab that is cut free in the hollow-cylindrical pot wall and is pivotable about an axis running tangentially to the hollow-cylindrical pot wall. A tightening element is rotatably mounted inside the built-in pot for tightening a fastening bolt of a second of the furniture parts which passes through the wall opening. The tightening element has an outer eccentric surface for spreading the at least one spreading tab. The at least one spreading tab has a free tab end that extends in an axial direction away from the pot bottom.

A connecting device includes a connecting element arranged on a connectible part, which includes non-self-cutting retaining projections having a curved supporting surface in the shape of a circular arc in a longitudinal section that are insertable into a groove provided on another connectible part. The groove has a curved undercut surface in the shape of a circular arc in a longitudinal section, a base segment, and two undercut segments extending away from the base segment in a thickness direction. The retaining projections engage in the undercut segments of the groove, the connecting means guiding the parts in relation to each other. One connecting element includes a guiding groove with a slotted guide and the other connecting element includes a guiding element moveable along the guiding groove in a specified guiding path having varying distances from a contact surface of the part and/or abutment surface of the connecting element.

A joining device with wide accessibility for parts of furniture and furnishing items, of a first panel to a second panel to be moved towards each other to bring an edge of the second panel abutted in a tightening position against a surface of the first panel, includes a blocking group and a connection group. The blocking group is inserted inside a seat defined within the first panel and receiving the blocking group, and includes a toothed crown, which is housed in a casing positioned in a first holing in the first panel and which controls the movement of a grub screw engaging a pin of the connection group. The casing includes a pair of half-shells that can be coupled with each other and that each contain a hole that is aligned on the two half- shells and with an additional holing of the shoulder intersecting the first holing.

A joining device for parts of furniture and furnishing accessories, including 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 provided with an expansion bushing externally projecting with respect to an open end of the 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, the joining device which includes a cam mechanism for a linear and reciprocated motion of an actuation unit co-operating in an expansion deformation movement of the expansion bushing and in a backward and traction movement of the same expansion bushing, with the cam mechanism and the actuation unit housed in the casing or container body and actuated by a tool.

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.

Adjustable concealed hanging device for furniture with an anti-tipping safety feature, of the type used for mounting kitchen furniture and the like, having a hanging hook that hooks onto a support plate screwed to the wall; and, together with the hanging hook, there is a V-shaped resilient shim with a broad upper edge, which upper edge, at the time of mounting, is located opposite the underside of the bend in the support plate.

A joining device with minimum visibility for parts of furniture and furnishing items, in particular connecting a first panel to a second panel, which must be moved towards each other in an approach direction to bring the edge of one panel buffered in a tightening position against a surface of the other panel, includes a blocking group and a connection group assembled on the panels. The blocking group is inserted inside a seat contained in the thickness of the panel on which the blocking group is applied, and the seat has a longitudinal axis perpendicular to the approach direction, and extending from an edge towards the inside of the panels.

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.

A locking device for a joinery product is provided, the locking device including a locking pin, and a rotatable plug element. The plug element has at least one engagement means configured to interact with the locking pin such that in a first rotation state of the plug element, the locking pin is positionable in a first position, and in a second rotation state of the plug element, the locking pin is positionable in a second position, different from the first position.
