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.

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 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.

A compact joint for connecting a first panel to a second panel of furniture and other furnishing items, positioned perpendicular to each other, includes a plurality of interconnection and blocking components for joining and firmly blocking the two panels together. The plurality of components of interconnection and blocking components lies on the same plane, which is perpendicular to the first and second panels and which contains a coupling axis between the first and second panels that travels inside the first panel. The joint also defines an actuation axis that is perpendicular to the coupling axis and lies on a plane parallel and interspaced with respect to the first panel and perpendicular with respect to the second panel.

A joint for firmly interconnecting a first panel and a second panel of furniture and other furnishing items positioned perpendicular to each other is provided with at least one fixing element coupled to the first panel and includes a plurality of interconnection and blocking components for joining and firmly blocking the two panels together, wherein, in the joint, the plurality of components lie on the same plane, which is parallel and interspaced with respect to the first panel and perpendicular with respect to the second panel.

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 connector assembly to fasten two members. The connector assembly includes an elongate fastener with an end for insertion into one of the members and a transverse aperture having at least one countersunk surface with an apex substantially aligned coaxially with the transverse aperture. The connector assembly also includes a grub screw insertable into the other member along a transverse axis substantially at the predetermined spacing from the shaped end. The connector assembly further includes a nipple formed onto one of the grub screw, the nipple being placeable into the transverse aperture for movement down the countersunk surface towards the apex thereof. The fastener moves with respect to the other member and brings the two fastened members closer together. The connector assembly also includes a housing for positioning the grub screw into the transverse aperture of the fastener, the housing having opposing apertures to allow the fastener to pass therethrough.
