Description

(1) An additional object of the present invention is to provide a motorized vehicle for transportation of people or goods which is competitive in terms of production costs. The structural and functional features of the present invention and its advantages over the known art will be clearer and more evident from the analysis of the claims below, and in particular from an examination of the following description, made with reference to the attached drawings showing a preferred but non-limiting embodiment of the present transportation vehicle, wherein:

(2) FIG. 1 is a perspective view of the present vehicle;

(3) FIG. 2 is a side view of the vehicle of FIG. 1 in a first operating position;

(4) FIG. 3 is a side view of the vehicle of FIG. 1 in a second operating position;

(5) FIG. 4 shows a perspective view of the vehicle of FIG. 3;

(6) FIG. 5 is a front view of the vehicle of FIG. 3;

(7) FIG. 6 shows an enlarged sectional view and with removed parts for clarity, a detail of the lifting cylinders of the present vehicle;

(8) FIG. 7 shows an enlarged and simplified view and with removed parts for clarity, a lifting column integrating the detail of FIG. 6;

(9) FIG. 8 shows an enlarged side view of the component of FIG. 7 in its variant and a first operating position; and

(10) FIG. 9 shows an enlarged side view of the component of FIG. 8 in a second operating position;

(11) With reference to FIGS. 1 to 5, V is generally referred to as a motorized vehicle used in the airports or similar infrastructures for the collective transportation of people, in particular for people with reduced or prevented mobility or with disabilities, people with priority access or technical security staff, or for the transportation of luggage or loads in general.

(12) The vehicle V includes an engine compartment A housing an electric engine or an internal combustion engine and/or a hybrid engine, a frame T of metal tubes type suitable to support, in a supporting manner and substantially enclosed therein, a closed cabin C (load cell) wherein people (generally indicated with Pe) are accommodated in order to be transported inside the airport area.

(13) The cabin C includes therein a driving seat 1 on the front of the vehicle V, a main area 2 for the accommodation and standing of people with annexed attachment means (known and not illustrated) of the wheelchairs for disabled people, some seats for the supporting staff and/or family members of the disabled people, or other means for transportation of various materials, a door 3 for the access of people inside the cabin C and for the exit towards the outside of the cabin C itself, and an emergency exit door 4.

(14) The door 3 is provided with platform means 5 (fixed, retractable and/or tilting) allowing the entrance/exit with easy access of the wheelchairs on which disabled people Pe are seated.

(15) The cabin C, which can be elevated from downside, is supported by a column system S with lifting uprights M suitable to perform the elevation of the cabin C itself in the frame T from a loading/unloading position PT of people at ground level (FIGS. 1 and 2) to an unloading/loading position PEA of people at the elevated level of the aircraft doors (FIGS. 3 and 4).

(16) As better illustrated in FIGS. 3, 4 and 5, the system S of lifting columns M is formed by at least three upright columns M, preferably two columns arranged fixed and acting at the opposite sides of the front of the vehicle V and one column arranged fixed and acting in the centre of the rear of the vehicle V.

(17) According to what specifically illustrated in FIG. 6, each lifting column M comprises a series 6 of cylinders (or extensions) 7 (four of which illustrated in FIG. 6) inserted into each other and suitable to slide through two internal hydraulic lubricated actuators 8 and 9 inside the cylinders 7, suitably dimensioned and of the double barrel or stem type, driven by sliding skids 10.

(18) This adopted solution is very advantageous as it allows for free inflection values, which are significantly lower than those of the traditional telescopic cylinder, thereby reducing the total dimensions of the stem section and cylinder sleeve itself.

(19) According to the variant shown in FIGS. 8 and 9, said hydraulic lubricated actuators are arranged fixed outside the cylinders 7 and acting outside the cylinders 7 themselves.

(20) As illustrated in FIGS. 7 to 9, a wheel 12 with a steering (idle and/or drive) axle for moving the vehicle V through the interposition of suspension means 13 is fixed at the lower end 11 of each column M.

(21) The suspension means 13 include the hydraulic lubricated cylinders 14 advantageously suitable to allow the passenger cabin C to be lowered to the ground level in said position PT and for the movement of the vehicle V itself at high speed. Moreover, such suspension means 13 may operate as stabilizer elements of the vehicle V, if necessary (configuration of FIG. 8).

(22) Finally, it should be noted that the vehicle V of the present invention can be advantageously used also for the transportation of the following groups of people:

(23) a) people with priority access to the airplane (first-class passengers, on-boarding directly from the First Class Lounge to the airplane, VIP passengers to ensure discretion) to ensure maximum comfort, service and utmost privacy.

(24) b) Airplane crew: particularly useful for Cargo airplanes.

(25) c) People in general: the present invention can also be extended in terms of size and ability to transport people, so it can actually become an elevating coach.

(26) Advantages are: 1) comfort (no need to take the stairs, no exposure to rain or, more generally, to bad weather (between coach, airplane or unloading station)), 2) speed (the on-boarding process is accelerated), 3) safety (no need to take the stairs).

(27) d) Transportation of cleaning/inspection/maintenance teams: these teams would thus become independent of stairs etc. and would be able to bring all the necessary tools directly to the right level.

(28) e) More generally, the invention will be used wherever people are needed to be transported safely and quickly, for distances up to a few kilometres, where the operations of loading and unloading of people occur at different height levels (from 0 up to 10 metres).
