Combination of a support device with a seat of a shelf

A combination of a shelf-supporting device and a shelf having a shelf seat for said shelf-supporting device, said shelf seat being defined within a thickness of said shelf of a piece of furniture to receive said shelf-supporting device for a reversible connection of the shelf to a shoulder of the piece of furniture, said shelf-supporting device comprising:

• a main body, which is slidingly associated with a connection pin movable between a first operating position, in which said connection pin protrudes from said shelf so as to be able to be inserted into a shoulder seat defined in the shoulder, and a second retracted position, in which said connection pin does not protrude from said shelf or protrudes but can still be released from said shoulder seat,
• wherein said shelf seat has an oval or circular cross-section,
• wherein said main body has an elongated shape defined by a longitudinal bevel on its upper surface and a longitudinally arcuate lower surface, or by a longitudinal bevel on its upper surface and a planar lower surface, the upper and lower surface being connected by longitudinal arcuate side surfaces, and
• wherein said main body has a cavity defined therein and a continuous front surface interrupted only by a hole sized to enable a passage of said connection pin, said connection pin being movable to protrude from said front surface,
• wherein the combination of the shelf-supporting device and the shelf defines a gap between the upper surface of the main body and an upper internal wall of the shelf seat,
• so that the upper surface of the main body does not come into contact with the upper internal wall of the shelf seat when the shelf-supporting device is assembled into the shelf;
• further comprising a seat, in correspondence with a front area of said main body having a solid portion, said seat being open on a lower surface of the main body and being configured to house a T-nut having a main body provided with a pass-through hole for passage of the connection pin and a base portion defining two flaps projecting laterally with respect to said main body of the T-nut.

A shelf-supporting device for a reversible connection of a shelf to a shoulder, the shelf-supporting device comprising:

• a main body slidingly associated with a connection pin movable between a first operating position, in which said connection pin protrudes from the shelf so as to be insertable into a shoulder seat formed in said shoulder, and a second retracted position, in which said connection pin does not protrude from said shelf or protrudes but can still to be released from said shoulder seat,
• wherein said main body has a shaped profile so that at least one portion of an upper surface of the main body does not come into contact with an upper internal wall of a shelf seat defined in a thickness of said shelf when the shelf-supporting device is assembled into the shelf,
• wherein said shelf-supporting device is configured to be received in a shoulder seat having an oval or circular cross-section, wherein said main body has a box shape comprising an upper surface disposed longitudinally, a lower surface disposed longitudinally, a front area from which the connection pin protrudes, and a pair of side surfaces, the front area having flattened upper and lower edges and being made as a solid portion with a continuous front surface interrupted only by a hole dimensioned to enable a passage of the connection pin,
• wherein said main body has an elongated shape having a transversal section with an upperly and lowerly flattened oval profile, in which the upper surface is planar along an entire length thereof, and
• wherein a distance exists between the upper surface of the main body and the upper internal wall of the shelf seat when the shelf-supporting device and the shelf are assembled,
• so that the upper surface of the main body does not come into contact with the upper internal wall of the shelf seat when the shelf-supporting device is assembled into the shelf.
