Device for sliding door leaves with co-planar closure, particularly for furniture and the like

A device including a closure arrangement for sliding door leaves to achieve co-planar closure of said door leaves, the device comprising a bracket system for connection to each one of said door leaves, the bracket system including a first pair of wheels associated in a lower region of the bracket system, a second pair of wheels, which, together with said first pair of wheels, are engaged slideably with a first guide and a second guide, respectively, said guides being T-shaped in cross-section, and having a head that is arc-shaped in cross-section, and a stem of which protruding from a top of a piece of furniture, and a third pair of wheels similar to said first and second pairs of wheels, the third pair of wheels being engaged slideably with said first guide, means adapted to force the closure arrangement of at least one of said door leaves being associated with said third pair of wheels, said third pair of wheels being arranged at a surface of a plate which during use is directed toward a base associated with said top of the piece of furniture and proximate to a longitudinal front edge of said plate which is adjacent to a front edge of the piece of furniture, said third pair of wheels being arranged on a same plane which is parallel to said top of the piece of furniture, said head being interposed between said wheels and being locked slideably between grooves of said third pair of wheels, which are connected rotatably with said means adapted to force the closure arrangement of at least one of said door leaves, said means adapted to force the closure arrangement of at least one of said door leaves being constituted by a V-shaped linkage, a first end of which is pivoted to said third pair of wheels and a vertex of which, directed toward said second pair of wheels, is pivoted to said plate, a second end of said linkage being engaged with an elastically elongatable spring element, which is coupled, at an end, to said plate, said spring element being unloaded in a condition in which the door leaf is closed.
