An actuation and blocking system of a joint for use in a piece of furniture or other furnishing item for perpendicularly interconnecting a shoulder with a shelf, base or top includes a pin with a fixing element to the shoulder and the shelf, base or top and adapted to be at least partially inserted in a hole of the shoulder and of the shelf, base or top. The pin has a side hole for receiving a shaped stem, which extends from an actuation and blocking group of the joint positioned on the shelf, base or top parallel to the floor or the ceiling, which are close to the furniture or other furnishing item when assembled, the actuation and blocking group providing for a 90? transmission between a maneuvering point, accessible from the front or side of the furniture, and the shaped stem, inserted in the side hole of the pin.

A joining system for use in furniture and furnishing items with a bottom and a shoulder has a front actuation axis under the bottom and includes a front joining unit and a rear joining unit positioned between the bottom and the shoulder of the furniture or furnishing item. A connection group is inserted in each front and rear joining unit and is aligned with a symmetry axis of the bottom, and a blocking group of the front and rear joining units is attached beneath the thickness of the bottom. The front joining unit provides an actuation and supporting member toward the rear joining unit, and the blocking group provides a grub screw inserted in a casing and caused to slide by way of a conical rack and pinion system, to be received in a bevel in the pin.

A fastener unit and related method for securing a board to a support is provided. The fastener unit includes a spacer block, a grip element extending from the spacer block and configured to fit in and engage a groove of the board, and one or more resilient compression elements extending from the spacer block. The one or more resilient compression elements can be a joist leg configured to engage a joist, or it can be vertically compressible toward a first plane that is transverse to a vertical axis of the spacer block so that portions of it can compress from an open mode to a compressed mode and fit within, then forcibly expand within the groove, thereby securing the spacer block in a position adjacent the groove to establish a gap between the board and another board. A related method of use also is provided.

A compact joining and leveling system for parts of furniture and furnishing items with a bottom and a shoulder includes, in combination, a front-foot unit and a rear-foot unit, wherein each front- and rear-foot unit includes a leveling group with a regulation mechanism in height that can be maneuvered with tools, wherein the leveling group of the front-and rear-foot units can be actuated from the front with respect to the piece of furniture through the space between the base and the floor, wherein the system also includes a connection group for stably interconnecting the bottom and the shoulder through a blocking element, and wherein the connection group can be actuated from the front with respect to the piece of furniture through the space between the bottom and the floor.

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.

In order to provide a connecting device for connecting two components, which is simple to manufacture and enables a stable and reliable connection of the two components, it is proposed that the connecting device comprises a main body which comprises a receiving channel extending through the main body for accommodating a fixing element, wherein the receiving channel is preferably accessible at one end by way of an insertion opening of the main body and/or preferably at a (further) end by way of a fixing opening of the main body, wherein the main body preferably further comprises an actuating opening that is different from the insertion opening and/or the fixing opening, by way of which in particular the fixing element arranged in the receiving channel is preferably accessible for the actuation thereof.

A set including a first element with a cylindrical shaped part, a second element having a cylindrical shaped groove with a circular opening in an outer surface of the second element, and a mechanical locking device. The mechanical locking device includes a tongue groove, a displacement groove and a flexible tongue in the displacement groove, and is configured to lock the cylindrical shaped part to the cylindrical shaped groove. The flexible tongue is configured to cooperate with the tongue groove for locking the cylindrical shaped part to the cylindrical shaped groove. The flexible tongue is configured to be reshaped and displaced in the displacement groove during locking, and spring back to a locked position. The flexible tongue is configured to exert a spring force on the tongue groove in the locked position.

A kit for assembling furniture, which comprises at least one panel, which defines externally two mutually opposite greater faces which are mutually joined by four side faces, at least one joining batten, and means of coupling between the panel and the batten; the coupling means comprise: a collar, which can be inserted into at least one first seat provided at one of the greater faces, and at least one pin, which can be partially inserted into at least one second seat provided at one of the side faces. The second seat leads to the first seat, in order to allow the introduction of a first end portion of the pin into a transverse hole of the collar, which is previously inserted into the first seat, with consequent definition of at least one intermediate configuration of assembly.

An actuation and blocking system of a joint for use in a piece of furniture or other furnishing item for perpendicularly interconnecting a shoulder with a shelf, base or top includes a pin with a fixing element to the shoulder and the shelf, base or top and adapted to be at least partially inserted in a hole of the shoulder and of the shelf, base or top. The pin has a side hole for receiving a shaped stem, which extends from an actuation and blocking group of the joint positioned on the shelf, base or top parallel to the floor or the ceiling, which are close to the furniture or other furnishing item when assembled, the actuation and blocking group providing for a 90? transmission between a maneuvering point, accessible from the front or side of the furniture, and the shaped stem, inserted in the side hole of the pin.
