Definitions

• the present invention refers to a transport vehicle equipped with an improved handling system for lifting and lowering loads, in particular aimed to lift and lower an upper loading flatbed of road vehicles .
• transport vehicles such as for example car transporters, equipped with various loading flatbeds, among which a lower loading flatbed, typically fixed, and at least one upper loading flatbed, moving to be lifted and lowered by a suitable handling system.
• object of the present invention is solving the above prior art problems, by providing a transport vehicle equipped with an improved handling system aimed to lift and lower loads, such as an upper loading flatbed for road vehicles, comprising at least one lifting mechanism equipped with a more compact structure, whose overall sizes are lower than what is proposed by the prior art .
• Figure 1 shows a side view of a preferred embodiment of the transport vehicle according to the present invention with an upper loading flatbed in a completely lowered position;

• Figures 5 and 6 show enlarged side views of a preferred embodiment of a lifting mechanism of the handling system of the transport vehicle according to the present invention respectively in a completely lowered position and in a completely lifted position;
• Figures 7 and 8 show rear top perspective views of the lifting mechanism of the handling system of the transport vehicle according to the present invention respectively in a completely lowered position and in a completely lifted position.
• the transport vehicle 1 according to the present invention of the type in particular aimed to transport other vehicles, such as for example car transporters, comprises at least two loading flatbeds 3a, 3b, of which at least the upper loading flatbed 3b must be able to be moved in height in order to allow a variety of configurations, and therefore of load: the transport vehicle 1 according to the present invention then further comprises a handling system of the upper loading flatbed 3b with respect to the lower loading flatbed 3a comprising at least one front lifting and lowering system 4 of such upper loading flatbed 3b and one or more lifting mechanisms 5 interposed between such loading flatbeds 3a, 3b cooperating with such front lifting and lowering system 4.
• a handling system of the upper loading flatbed 3b with respect to the lower loading flatbed 3a comprising at least one front lifting and lowering system 4 of such upper loading flatbed 3b and one or more lifting mechanisms 5 interposed between such loading flatbeds 3a, 3b cooperating with such front lifting and lowering system 4.
• such front lifting and lowering system 4 comprises at least one pair of vertical movement actuators arranged on the front of such loading flatbeds 3a, 3b, each one of such actuators being arranged along a respective vertical riser 6 and these one or more lifting mechanisms 5 being arranged on the rear to such loading flatbeds 3a, 3b, the terms "front” and “rear” being referred to the travelling direction of the vehicle 1 according to the present invention.
• such vertical movement actuator is composed of an actuating mechanism of the type with guide with worm screw, of a substantially known type in the art .
• such lifting mechanism 5 of the transport vehicle 1 comprises at least one internal body 7 having a first end 7a thereof connected in an articulated and rotating way to at least one external structure 9 integral with the vehicle 1 itself, and at least one external body 11 having a first end 11a thereof connected, preferably in an articulated way, to the upper loading flatbed 3b, such external body 11 being constrained to the internal body 7 through a coupling of a sliding type, which allows the external body 11 to perform only translation movements with respect to the internal body 7 along a relative sliding direction designated in Figures 5 and 6 by axis X-X (therefore, along a Cartesian reference plane XY integral with the internal body 7 and oriented as shown in Figures 5 and 6) , at least one movement actuator (not shown) operatively cooperating with the external body 11 and the internal body 7 to perform such translation movements along the relative sliding direction X-X of such external body 11 with respect to such internal body 7, and at least one connecting rod-type kinematism 13 having a first end
• the external structure 9 is therefore preferably arranged substantially at the height of the lower loading flatbed 3a and the first end 11a of the external body 11 is connected in an articulated way to the upper loading flatbed 3b.
• the use of one or more suitably arranged lifting mechanisms 5 and their actuation in cooperation with the front lifting and lowering system 4 allows a lowering and a lifting of the upper loading flatbed 3b with respect to the lower loading flatbed 3a, allowing not only to lift and lower such upper loading flatbed 3b always parallel thereto, but also to incline it.
• the lifting mechanisms 5 according to the present invention are arranged on the left and right sides of the vehicle 1 according to the present invention, in order to avoid lifting and lowering misalignments of the upper loading flatbed 3b, it is possible to provide that, as it is possible to note in particular in Figures 7 and 8, the corresponding mechanisms 5 on two different sides are mutually connected by at least one connecting structure 15 such as, for example, at least one torsion bar, to make their movement synchronous .
• the sliding surfaces of these two parts can be equipped with suitable means (not shown in the Figures) to reduce the friction resistances.
• articulated connections where provided, between the various component parts of the lifting mechanism 5 of the vehicle 1 according to the present invention, can be made by interposing any mechanism or kinematism, such as for example a hinge, suitable for such purpose.
• the movement actuator though it can be preferably composed of a hydraulic cylinder, can be any other mechanism or kinematism capable of providing a linear movement, such as, for example, at least one pneumatic cylinder, screw/nut systems actuated by hydraulic, electric, pneumatic motor, etc .
• the movement actuator has a first end thereof connected in an articulated way to the lower part of the internal body 7 and a second end connected in an articulated way, for example through a hinge, directly to the external body 11.
• the external body 11 is further equipped with at least one connection point of the first end 13a of the connecting rod-type kinematism 13.
• the movement actuator is contained in at least one hollow space (not shown) obtained between the internal body 7 and the external body 11, and the relative sliding direction X-X coincides with and/or is parallel to the linear movement axis of the actuator itself.
• the elongation of the movement actuator takes the lifting mechanism 5 progressively from the position in Figures 1, 3, 5 and 7 to the position in Figures 2, 4, 6 and 8, simultaneously generating the elongation of the lifting mechanism 5 for the coherent sliding of the external body 11 along the internal body 7 (along the direction pointed out by arrow A in Figure 5) and the rotation of the lifting mechanism 5 (along the direction pointed out by arrow R in Figure 5) , around the first end 7a connected in an articulated way to the external structure 9, taking the first end 11a of the external body 11 to be elevated and, consequently, to lift the loading flatbed 3b connected thereto.
• the transport vehicle according to the present invention has been shown as an example as a truck, but it is wholly evident that it can be configured in any other structure, such as, for example a trailer or semi-trailer for road transport, or a wagon for the railway transport, without thereby departing from the scope of the present invention, as claimed in the attached claims.
• the transport vehicle according to the present invention allows reaching the stated objects.
• its own handling system allows, through the cooperation between the vertical movement actuators and the type of lifting mechanism being used, providing several advantages with respect to prior art vehicles, among which: by blocking the movement actuator, the handling system, and in particular the lifting mechanism, is in a stable position;
• the effort exerted by the movement actuator is more constantly distributed along the stroke ;
• the lifting mechanism in its lowered position is more compact with respect to the prior art mechanisms, decreasing the rear projection from the lower loading flatbed.
