  • the present invention relates toa self-propelled-handling truck, more particularly intended for-the transshipment of 5 mailboxes for airmail traffic.
  • Handling means are of course, already known for loading or unloading aircraft, but some of these utilize the frequent toand-fro traffic of hauled tracks, which renders the operating time excessive, while others necessarily comprise very considerable fixed installations on the ground, which is not systematically suitable for all aerodromes intended to receive airmail freight.
  • the present invention provides an automatic handling truck which does! not possess the above disadvantages, and which possess furthermore, as will be explained in more detail in the remainder of this text, a high mobility permitting easy utilization in the small spaces available, which may furthermore comprise irregular ground or interrupted slopes.
  • the self-propelled truck according to the invention is essentially characterized in that is comprises a plurality of elements coupled to each other so as to give the whole assembly acertain vertical flexibility, whilst retaining greathorizontal rigidity; in that it possesses, by virtue of a particular arrangement of its rolling members, six degrees of freedom, namely two for longitudinal translation, two for transverse translation and two for rotation in position; in that it comprises passages for the translation and transfer of loads in waiting zones;,in that it is provided with a system for drawing-alongside'the' loading or unloading area in such manner that this latter may have variations in surface without interfering ,withthe movement of loading in the passages; and in that it has asingle operating cabin and a driving unit for the control of these evolutions and of the movement of the loads, together with the operation of the associated controlled devices.
  • the invention also provides a L gearbox system with two ratios, which permits a normal speed of the truck (20 to 30 km./hr.) and a lower speed for maneuvering, thedisplacement of the loads on the truck being effected by driving rollers (retractable) and lateral guides (withdrawable).
  • FIGS. 1 to 8 are diagrammatic sketches showing the advantage of the system of handling loads obtained by the use of the truck in accordance with the invention
  • FIG. 9 is a diagrammatic longitudinal view showing the complete operation of the transfer of 14 mailboxes.
  • FIG. I0 is a perspective view of the whole of a self-propelled truck
  • FIG. 11 is a perspective view showing the front element of the truck of FIG. 10, together with the boarding device;
  • FIGS. 12 to 15 are diagrammatic sketches showing the possible evolutions of the truck
  • FIG. 16 is a diagrammatic sketch of the kinematic chain of the directional control of the rolling membersof the truck shown in FIG. 1;
  • FIG. I7 is a diagrammatic sketch of the kinematic chain of the driving control of this same truck.
  • FIG, 18 is a'diagrammatic sketch showing the control panel mounted inthe driving cabin.
  • FIGS. 1 to 8 will explain, diagrammatically and by way of example, the case of a transfer of loads to be effected between the luggage room of an aircraft indicated A and an unloading platform indicated at B. i
  • a truck C will more transversely and longitudinally so as to come into position against the platform B.
  • FIG.-2 the boxes a and b are brought on to the truck so as to be placedin awaiting zone Ca.
  • the two boxes c, d are transferred to the waiting zone, while thetwo boxes a, b are placed in their turn in the transfer zone.
  • the-boxed a, b, c-p are brought into the hold A of the aircraft, which may then evacuate the parking area, while the boxes c, d will be replaced in the transfer zone.
  • the essential characteristics of the truck according to the invention permit essentially two particular functions, namely the possible displacement of the loads between the so-called transfer zones Cr and the so-called waiting zones Ca, these being provided in numbers following any desired arrangement, and the particular means of maneuver of the .truck, which consist of arranging two pivoted driving wheels in.diabolo Crl, Cr2 in the front and rear parts of the truck.
  • a truck with four coupled elements including two driving and twocarrier elements is capable of transferring in a single operation the complete load of the hold of an aircraft comprising l4 frames of mailboxes.
  • the truck which is shown in FIG. 10 comprises essentially, in addition to two transfer zones Crl, Cr2, two waiting zones Cal; and Ca2, two driving diabolos Crl, Cr2, and
  • the element 1 which is shown in more detail in FIG. 11 is constituted by a carrier chassis 11 coupled to the element 2 and it receives, on the one hand, two freely pivoted rolling members 12 and I3 and, on the other hand, a plate 14 carrying guiding rails for handling devices together with a system of boarding,,which will be described in detail later.
  • the carrier chassis 11 receives a plate 14 movable about the axes 15a and I5! and at I6 so as to be capable of takingup a skewed position on the said chassis.
  • this carrier chassis 1 1 receives the control cabin 124 and also the pivots of the free diabolo wheels 12 and 13.
  • the elements 2, 3 and 4 which are similar to the element 1 in their handling function, comprise the transfer zones Ctl, Cr2, in which retractable guides 24 form passages, while the rollers 22 freely pivoted, and the retractable driving rollers 23 ensure the lateral movement of the loads.
  • Working platforms 25 provided with handrails 125 enable the operators D to handle the loading easily, and the driving diabolo Cr2 with its driving rollers 126 is arranged underneath the element 2, while free diabolos 26, 27, 28 and 29 pivot underneath the elements 2 and 4.
  • a driver E installed in the cabin I24, controls the operations of the truck and supervises the handling movements carried out by the operators D.
  • the particular maneuvers of the handling truck according to the invention are obtained by a certain arrangement of the rolling driver members, which have a vertical pivotal axis, and their pivotal movement is effected at a distance by means of a centralized control.
  • FIGS. 16 and I7 illustrate the kinematic chain and the driving chain which permit the maneuvering of the truck shown in FIG. 10.
  • FIG. 16 it can be seen that the diabolos Crl and Cr2 pivot about the vertical axis X1, X2 (associated with the elements 1 and 3 of the truck C) and the pivotal movement is effected by endless screws 30 and tangent wheels 31 coupled to each other by a shaft 32 which is self-aligned by the homokinetic joint 33.
  • a servomotor 34 actuated by the steering wheel 35 ensures the turning of the diabolos Crl and Cr2 in a manner known per se.
  • FIGS. 12 to 15 it is seen that the maneuvering of the truck C necessitates the combination of two means which are, on the one hand, the angular orientation of the diabolos Crl and Cr2 about X1 and X2 and, on the other hand, the proper direction of rotation of the driving members.
  • FIGS. 12 and 13 have their rolling members turned in the same direction, it is seen however that different evolutions are obtained (a lateral or rotational movement) by simply changing the direction of rotation of the driving members Crl and Cr2.
  • FIG. 17 shows the kinematic chain which permits (by means of a first reversing gear with two positions I and D (reverse and direct) the reversal of the direction of rotation of the driving members Crl and Cr2 with respect to each other or, by means of a second reversing device 37 with two positions I and D, the simultaneous reversal of the direction of rotation of these same driving members.
  • the two reversing gears 36 and 37 operate in a conventional manner with, for example, a clutch 38 (electromagnetic or the like) pennitting the two shafts a1 and 02 to be coupled together in direct engagement, in a first position D, a sliding gear e1 on 01 enabling the shaft 02 to be driven by other gears e2, e3, e4 and e5 in a second position I and by declutching of 38.
  • a clutch 38 electromagnet clutch
  • a torque converter 39 associated with a gearbox 40 with two speed variation ratios (V1 rapid speed, V2 slow speed) coupled to a motor 41 ensures the mobility of the unit, while a bevel gear 42 brings the movement on the driving shaft 01 selfaligned by the homokinetic joint 43.
  • the driving of the truck which is effected from the desk shown in FIG. 18, comprises two possibilities: the normal maneuvers and maneuvers in situ.
  • direction counterclockwise Button 52 controls reversing gear 37 (direct engagement) controls reversing gear 36 (direct engagement) 25 Pivotal movement in situ
  • clockwise direction Button 53 controls reversing gear 37 (reverse position) controls reversing gear 36 (direct engagement) miLateral movement to the left Button 54-controls reversing gear 37 (direct engagement) controls reversing gear 36
  • the invention provides a self-propelled 5Q handling truck which is particularly well adapted to the traffic of airmail bags, although its utilization may be contemplated for all load-handling in general.
  • the invention is essentially concerned with the production of a vehicle of very large size, provided, by the special arrangement of its rolling, propulsion and steering members with high maneuverability, facilitating the operations of drawing alongside and maneuvers on airport areas, and is applicable to the loading and unloading of freight from aircraft with a low floor or from aircraft with a high floor, the skewing plate being then replaced by a built-in scissors-type elevator.
