Furniture element comprising a supporting plane and a device for handling a furniture element for a multipurpose vehicle, said device being suitable for being made integral with the structure of the mentioned vehicle, with said furniture element comprising a supporting plane and with the above said device comprising: - at least a vertical guide, in which is slidably engaged at least one slide associated to said supporting plane and intended to enable the latter to a vertical excursion between a raised position and a lowered position, and vice versa; - at least one levers kinematism, comprising a first lever, articulated with one end to a fulcrum having a fixed position, and a second lever, articulated with one end to said slide, the same first and second levers (51, 52) being mutually articulated in correspondence of the respective free ends and intended to reach two peculiar configurations, open and closed, respectively in correspondence of the mentioned raised positions and lowered position of the above said supporting plane; - at least one elastic compression member, articulated with its ends to the mentioned first and second levers (51, 52), according to a geometry such that when said levers kinematism is in the closed configuration the push action of said elastic member urges said levers (51, 52) in a direction tending to stabilize their closed configuration and the mentioned lowered position of the supporting plane, while, when said levers kinematism is moved by a predetermined amount from said closed configuration, the push action of the same elastic member urges said levers (51, 52) in a direction tending to determine the automatic lifting and the stabilization of said open configuration of the levers (51, 52) and the mentioned raised position of the same supporting plane characterized in that the mentioned first lever is shaped square angled, and that an eyelet provided on the same for the first articulation of said elastic compression member is located close to the corner formed by the two branches (51A, 51B) of said first lever, in that the mentioned second lever has a substantially rectilinear shape, with a length similar to that of the first branch of said first lever, and that a corresponding eyelet provided on it for the second articulation of said elastic member is located in an appendix projecting laterally from the same second lever, close to a fulcrum according to which the latter is articulated to said slide, in that in the mentioned closed configuration the first square angled lever is arranged with its first branch substantially orthogonal to said vertical guide, the said second lever is substantially parallel to the same first branch and said elastic member is in the condition of minimum extension, inclined so that its axial push action has a force component tending to keep the mentioned parallelism between the same levers (51, 52), so that the said displacement imparted to the latter must determine the overcoming of a dead point beyond which the elastic push force is able to make them open as a compass, and in that in the mentioned open configuration the said first and second lever (51, 52) are mutually almost orthogonal and said elastic member is in the condition next to the maximum extension, inclined so that its axial push action has a force component tending to increase the angle formed by the same levers (51, 52). - at least a vertical guide, in which is slidably engaged at least one slide associated to said supporting plane and intended to enable the latter to a vertical excursion between a raised position and a lowered position, and vice versa; - at least one levers kinematism, comprising a first lever, articulated with one end to a fulcrum having a fixed position, and a second lever, articulated with one end to said slide, the same first and second levers (51, 52) being mutually articulated in correspondence of the respective free ends and intended to reach two peculiar configurations, open and closed, respectively in correspondence of the mentioned raised positions and lowered position of the above said supporting plane; - at least one elastic compression member, articulated with its ends to the mentioned first and second levers (51, 52), according to a geometry such that when said levers kinematism is in the closed configuration the push action of said elastic member urges said levers (51, 52) in a direction tending to stabilize their closed configuration and the mentioned lowered position of the supporting plane, while, when said levers kinematism is moved by a predetermined amount from said closed configuration, the push action of the same elastic member urges said levers (51, 52) in a direction tending to determine the automatic lifting and the stabilization of said open configuration of the levers (51, 52) and the mentioned raised position of the same supporting plane
