LASZLO NEMESSANYI PAIENTEUNBY 30 IQYI 3 623 6 1 7 sum 2 [1F 2 FIGURE 6 INVENTOR: FIGURE 9 LASZLO NEMESSANYI CARGO-HANDLING DEVICE HAVING A TILT- ADJUSTING SYSTEM BACKGROUND OF THE INVENTION The efficient handling of a cargo by a cargo-handling device, particularly cargo that is transported by aircraft, requires cargo unitization which can be in the form of loaded pallets and containers. These pallets and containers have been maximized dimensionally to minimize the total number of shipping units that are handled. However, the increased dimensions of the shipping units reduce door opening clearances so that loading and off-loading requires an increased amount of time to accurately position the shipping unit so that neither the door frame nor the unit is damaged as the unit moves through the door opening. Therefore, a cargohandling device must accurately position the shipping unit relative to the door opening or to the plane of an adjacent load-bearing surface where there is no door opening.

Where the adjacent load-bearing surface is the cargo compartment floor of an airplane, the cargo-handling device must also adjust to the plane surface of the floor when the floor shifts about the roll axis of the airplane during loading and offloading of cargo.

OBJECTS OF THE INVENTION Accordingly, it is an object of the invention to provide a new and improved cargo-handling device.

It is an object of the invention to provide a cargo-handling device having an adjustable load-supporting surface.

It is an object of the invention to provide a cargo-handling device having a tilt-adjusting system.

SUMMARY OF THE INVENTION Briefly, in accordance with the invention, a cargo-handling device is provided having a load-supporting bed carried by a base and movable by an elevating means from a first position where the bed and base are parallel to a second position where the bed and base are parallel but spaced apart. A tilt-adjusting system selectively changes the tilt of the bed to a third, nonparallel position and automatically changes the bed to the second parallel position when the elevating means moves the bed from the third nonparallel position to the first parallel position.

While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter which may be regarded as the invention, the organization and method of operation, together with further objects, features, and the attending advantages thereof, may best be understood when the following description is read in connection with the accompanying drawing.

FIG. 9 is an enlarged elevation view of the tilt-adjusting system of FIG. 3 as the device moves into the first position of FIG. 1.

DESCRIPTION OF THE INVENTION Referring to FIG. 1, one form of cargo-handling device 10 is shown wherein the tilt-adjusting system 12 of the present invention can find particular use. The cargo-handling device 10 has a base 14 and a load-supporting bed 16 interconnected by an elevating means such as the crossed scissors legs 18 and 20 which are paired with similar scissors legs (not shown). The scissors legs 18 and 20 are pivotally connected at 22. A linear actuator such as a hydraulic ram 24 acts upon the crossed scissors legs 18 and 20 to lift or move the load-supporting bed 16 from the adjacent position as shown by FIG. I to a spaced apart second position as shown by FIG. 2. Scissors leg 18 is pivotally connected to the load-supporting bed 16 at pivot connection 26 with a suitable roller 28 at the other end adapted to roll in a complementary track on the base 14. Scissors leg 20 is pivotally connected to the base 14 at pivot connection 30 and has a cam follower roller 32 described hereinafter in greater detail.

In the adjacent or stored position as shown by FIG. I, the load-supporting bed 16 defines a plane which is substantially parallel with a similar plane defined by base 14. Similarly, in the spaced apart or elevated position as shown by FIG. 2, the load-supporting bed 16 again defines a plane which is substantially parallel with the plane defined by the base 14.

Referring to FIGS. 3 and 4, the tilt-adjusting system 12 has a cam 36 suitably formed into a dogleg configuration such as is shown by FIG. 3 so that the cam develops a predetermined cam surface profile. The cam follower roller 32 engages the cam surface profile of cam 36 and transverses the cam as the scissors legs I8 and 20 are adjusted by the hydraulic ram 24.

The cam 36 is rotatably supported at end 40 in a suitable bearing 42. End 44 of cam 36 is connected to one end of a connecting link 46 that is connected to a stub shaft 48. Shaft 48 is rotatably positioned by similar bearings 50, preferably with the longitudinal axis of the stub shaft 48 positioned concentrically with the rotational axis of the cam 36. The rotational axis of the cam 36 extends longitudinally through a first cam portion 52 which is journaled at end 40 in the bearing 42. An actuating rod 54 connected to and extending outwardly from the stub shaft 48 is connected to a yoke 58 that extends from a suitable actuator 60 which is considered to be conventional. The link 46, stub shaft 48, and rod 54 are generally arranged to function mechanically as a bell crank arrangement 56. A second cam portion 62 of cam 36 develops the major portion of the dogleg configuration of the cam. When the cam 36 is rotated about the longitudinal cam axis by the bell crank arrangement, the second cam portion 62 generates an imaginary warped surface.

In FIG. 5, the tilt-adjusting system 12 of the cargo-handling device 10 has been rotated to adjust the tilt or pitch of the load-supporting bed 16 so that the plane defined by the bed is no longer substantially parallel with the plane defined by the base 14. The bell crank arrangement rotates the cam 36 about its longitudinal cam axis and drives the roller or cam follower 32 along the cam surface profile until a desired tilt of the loadsupporting bed 16 is reached.

The cargo-handling device 10 with the tilt-adjusting system 12 of the present invention adjusts the tilt of a load-supporting bed when loading or off-loading cargo into or from an adjacent plane surface such as the cargo compartment floor of an airplane as schematically shown by FIG. 6. Airplane has a longitudinally extending roll axis 72 about which the airplane may roll or shift as cargo is loaded or off-loaded.

When the airplane 70 is at rest and is either empty of or evenly loaded with cargo, the plane surface defined by the cargo compartment fioor of the airplane is coextensive with the plane surface defined by the load-supporting bed; this coextensive plane is represented by line 74 in FIG. 6. When the airplane 70 rolls or shifts about the roll axis 72 in the counterclockwise direction as viewed in FIG. 6, the plane of the floor is tilted. The tilt or pitch of the load-supporting bed 16 is adjusted by the tilt-adjusting system 12 so that the plane of the bed is coextensive with the floor as represented by line 76 in FIG. 6 when the tilt-adjusting system 12 is positioned as shown by FIG. 7.

When the airplane 70 rolls or shifts about the roll axis 72 in the clockwise direction as viewed in FIG. 6, the plane of the floor and the plane of the bed are maintained coextensive as represented by line 78 when the tilt-adjusting system 12 is positioned as shown by FIG. 8.

It is desirable to be able to rapidly remove the cargo-handling device 10 from the area adjacent to a cargo carrier or storage area. The load-supporting bed 16 in the nonparallel relationship with base 14 as shown by FIG. is automatically returned to the parallel collapsed or stored position as shown by FIG. 1 where the bed 16 is adjacent to the base 14 without the further adjustment of the tilt-adjusting system 12, i.e. rotation of the cam 36 by the bell crank arrangement 56. As the load-supporting bed [6 is returned by the elevating system from the third position as shown by FIG. 5 to the first position as shown by FIG. 1, the roller or cam follower 32 traverses the cam surface profile of cam 36 until the cam follower reaches the first cam portion 52 which lays coextensively along and generally concentric with the longitudinal cam axis. Since the first cam portion is substantially parallel with not only the bed 16 but also the base 14, the load-supporting bed 16 is automatically returned to its parallel relationship with the base so that the bed can be collapsed and stored with the base without adjustment of the bell crank arrangement 56 and cor respondingly the cam 36.

As will be evidenced from the foregoing description, certain aspects of the invention are not limited to the particular details of construction as illustrated, and it is contemplated that other modifications and applications will occur to those skilled in the art. It is, therefore, intended that the appended claims shall cover such modifications and applications that do not depart from the true spirit and scope of the invention.
