Dimensionally adjustable vehicle

1. A dimensionally adjustable vehicle that is adjustable both lengthwise and widthwise simultaneously, comprising a platform of pivoting and non-pivoting plates arranged such that the spacing between a pair of said non-pivoting plates is changed to dimensionally adjust said vehicle upon application of an initiating force to a plurality of said pivoting plates which causes a pivoting motion, characterized in that at least one of said pivoting plates is a jointly pivoting plate that is both laterally pivoting and longitudinally pivoting and that is pivotally connected to a plate in a central section and to a plate in a forward or rear section.

2. The vehicle according to claim 1 , wherein a section of the platform comprises a pair of laterally adjacent and laterally pivoting plates which is interposed between a pair of the non-pivoting plates such that a lateral side of each of said laterally pivoting plates is pivotally connected to a lateral side of an adjacent non-pivoting plate, application of the initiating force to at least one of said pair of laterally adjacent and laterally pivoting plates causing a lateral dimension of the vehicle to be adjusted.

3. The vehicle according to claim 1 , wherein the jointly pivoting plate comprises a protruding plate and a recessed plate that are fixedly connected to, or integrally formed with, each other.

4. The vehicle according to claim 3 , wherein the recessed plate is pivotally connected to a longitudinal side of a laterally pivoting plate in the central section and to a laterally adjacent longitudinally pivoting plate.

5. The vehicle according to claim 3 , wherein the protruding plate is pivotally connected to a laterally adjacent protruding plate and to a longitudinal side of a laterally pivoting plate in the forward or rear section.

6. The vehicle according to claim 1 , wherein the platform further comprises a plurality of longitudinally extendable and contractible plates which are displaceable during a longitudinal adjustment operation.

7. The vehicle according to claim 6 , wherein a first longitudinally extendable plate is connected to a non-pivoting plate in the forward section, a second longitudinally extendable plate is connected to a non-pivoting plate in the rear section, and a third longitudinally extendable plate is interposed between, and telescopingly connected to, said first and second longitudinally extendable plates.

8. The vehicle according to claim 5 , wherein the central section comprises two pairs of laterally pivoting plates and the initiating force is applied simultaneously to two laterally adjacent laterally pivoting plates in the central section.

9. The vehicle according to claim 1 , wherein the jointly pivoting plate is pivotally connected to a laterally pivoting plate in the central section and to a laterally pivoting plate in the forward section or in the rear section, thereby transmitting the initiating force to the laterally pivoting plate in the forward section or in the rear section and causing both a lateral dimension and a longitudinal of the vehicle to be simultaneously adjusted.

10. The vehicle according to claim 2 , further comprising a force initiator for applying the initiating force to a plurality of the pivoting plates.

11. The vehicle according to claim 10 , wherein the force initiator is a jack device comprising a linkage which is in force transmitting relation with two laterally spaced laterally pivoting plates, operation of said jack device causing said two plates to be laterally pivoted and the platform to undergo a dimension adjusting operation in response the lateral pivoting of said two plates.

12. The vehicle according to claim 10 , wherein the force initiator is a jack device comprising a linkage which is in force transmitting relation with two longitudinally spaced laterally pivoting plates, operation of said jack device causing said two plates to be longitudinally pivoted and the platform to undergo a dimension adjusting operation in response the longitudinal pivoting of said two plates.

13. The vehicle according to claim 1 , further comprising a support beam located below all plates of the platform and two stabilizing units for stabilizing the platform upon conclusion of a dimension adjusting operation, said two stabilizing units being pivotally connected to said beam and to a non-pivoting plate in the front and rear sections, respectively.

14. The vehicle according to claim 13 , wherein each of the two stabilizing units is fixatable.

15. The vehicle according to claim 1 , wherein the plates of the central section are located below or above the plates of the front and rear sections.

16. The vehicle according to claim 1 , further comprising means for reorientating one or more seat assemblies during a dimension adjusting operation.

17. The vehicle according to claim 2 , wherein the laterally pivoting plates are trapezoidal, symmetrical, and elongated.

18. The vehicle according to claim 1 , wherein a folding mechanism for changing the dimensions of the platform is implemented such that a plurality of interconnected rigid incompressible pivoting plates extends downwardly.

19. The vehicle according to claim 10 , which is dimensionally adjustable when in transit.

20. The vehicle according to claim 19 , wherein all of its wheels are independently driven by a corresponding electric motor, the vehicle further comprising an onboard computer in electrical communication with each of said motors and with the force initiator, for commanding each of the wheels to follow a predetermined path in order to ensure that the vehicle continues to travel stably despite undergoing a dimension adjusting operation.
