Support device for furniture shelves

A shelf-supporting device (1, 1′, 1″) for a reversible connection of a shelf (200) to a shoulder (300) of a piece of furniture, said device being configured for being inserted inside a shelf seat (101201) formed within a thickness of said shelf (200) and comprising:

• a main body (12, 12′, 12″) which is slidingly associated with a connection pin (11) movable between a first operating position in which said pin (11) protrudes from said shelf (100) so as to be able to be inserted into a housing seat (301) defined in said shoulder (300), and a second retracted position in which said pin (11) does not protrude from said shelf (200) or protrudes so as to be able to be in any case released from said housing seat (301),
• wherein said main body (12, 12′, 12″) comprises, on its an outer surface thereof, one or more projecting elements (13) which extend towards an outside of said main body (12), and which are configured so that forces that the pin (11) transfers to the shelf-supporting device (1) are discharged onto the shelf through said one or more projecting elements (13), and
• wherein said one or more projecting elements (13) extend along an entire length of side surfaces (12e, 12e′, 12e″) of said main body (12, 12′, 12″), have a greater transverse extension in correspondence with a front area (14) of the main body (12, 12′, 12″), and are tapered, reducing an overall dimensions of said one or more projecting elements (13) in a transverse direction towards a rear area of the shelf-supporting device (1, 1′, 1″) opposite the front area (14).
