Abstract: 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.

Abstract: A connecting device between components of a piece of furniture includes a casing capable of being received in a first seat and in a second seat obtained respectively in a first and in a second component of the piece of furniture, and including a first and a second radially expandable region to engage respectively the first and the second component in correspondence of the first and the second seat, a tie rod received inside the casing with axial sliding power towards and from a locking position, and including a first segment in enlarged section and a second segment in enlarged section susceptible of engagement respectively with the first and the second region to determine a radial expansion of the casing when the rod is moved in the locking position, and an eccentric element arranged to engage a head of the tie rod and axially move it towards the locking position when the eccentric element rotates around its main axis.

Abstract: A method for the production of a connecting device for the components of piece of furniture, characterized in that it includes the steps of preparation of a casing extending along a longitudinal axis and provided with a first and a second half-shell both concave and mutually rotatably connected in correspondence of a reciprocal connecting line defining an tilting axis, in which said half-shells are mutually put side by side with the respective concavities facing upwards, predisposition of at least one tie rod, predisposition of at least one eccentric element and at least one tie rod, tilting of the second half-shell around the axis from the open position to a closed position, in which the half-shells are mutually abutted in correspondence of respective peripheral edges and the respective concavities defining the housing space for the tie rod and the eccentric element.
