The track assembly includes top plate 204, which incorporates the tracks 206. In FIG. 18, dashed lines have been added to show the portion of the top plate 204 that is used as the track 206 for the rollers 214. The interaction of the rollers 214 and track 216 is similar to the interaction of rollercoaster wheels and their associated track. In operation, small vertical rollers 214c ride against the side edge of top plate 204 (as can be seen in FIGS. 17a and 30a), small horizontal rollers 214b ride against the underside of top plate 204 (as can be seen in FIG. 30a), and the large horizontal roller 214a rides on the top of top plate 204 (as can be seen in FIG. 30a). This allows the moving tower 202 to travel from one end of the track assembly 200 to the other. As is described above, this rolling movement takes place when the platform 13 is folded and pulls the first vertical arm 42, and, therefore, the moving tower 202 inwardly.

What is claimed is: 1. A wheelchair lift for use in conjunction with a vehicle having a floor, the lift comprising: a power actuating system; a platform assembly comprising at least first and second platform sections; a linking assembly connecting the power actuating system to the platform assembly, the linking assembly having first and second vertical arms connected to the platform assembly; and first and second fold-facilitating links connected to the first and second vertical arms respectively and the first and second platform sections, wherein during a folding process, the first and second fold-facilitating links cause the first platform section to pivot with respect to the second platform section and the first vertical arm to move with respect to the second vertical arm. 2. The wheelchair lift of claim 1 wherein the first and second sections of the platform each have a top surface and a bottom surface, wherein in the fully extended configuration, the bottom surfaces of the first and second sections face the same direction and wherein in a stowed position, the bottom surface of the first section faces the bottom surface of the second section. 3. The wheelchair lift of claim 1 wherein the first and second sections of the platform are pivotally connected at and foldable along their adjacent longitudinal edges perpendicular to an extended edge of the vehicle floor. 4. The wheelchair lift of claim 1 wherein the fold-facilitating link includes a turnbuckle. 5. The wheelchair lift of claim 4 wherein the linking assembly comprises a parallelogram actuating structure connected to the power actuating system to rotate about a fixed axis and actuate the first and second vertical arms. 6. The wheelchair lift of claim 5 further comprising a saddle assembly connected to the vertical arm and configured to engage the parallelogram actuating structure, wherein during the folding process, the saddle assembly engages the parallelogram actuating structure. 7. A wheelchair lift for use in conjunction with a vehicle having a floor, the lift comprising: a power actuating system; a platform assembly including first and second platform sections; a linking assembly connecting the power actuating system to the platform assembly, the linking assembly having first and second vertical arms connected to the platform assembly, wherein at least one of the first and second vertical arms is movable toward the other vertical arm; first and second fold-facilitating links connecting the first and second vertical arms respectively to the first and second platform sections, wherein during movement of at least one of the vertical arms towards the other vertical arm, the fold-facilitating links cause the platform to fold along a longitudinally oriented fold pivotally connecting the first and second platform sections. 8. A wheelchair lift for use in conjunction with a vehicle having a floor, the lift comprising: a power actuating system; a platform assembly including first and second platform sections; a linking assembly connecting the power actuating system to the platform assembly, the linking assembly having first and second vertical arms connected to the platform assembly, wherein at least one of the first and second vertical arms is movable toward the other vertical arm; at least one fold-facilitating link disposed between the first vertical arm and the first platform section, wherein during movement of at least one of the vertical arms towards the other vertical arm, the at least one fold-facilitating link causes the platform to fold along a longitudinally oriented fold pivotally connecting the first and second platform sections, and wherein the track assembly includes at least one track and the linking assembly includes at least one roller, and wherein the at least one roller and at least one track cooperate to make at least one of the first and second vertical arms moveable. 9. The wheelchair lift of claim 8 wherein the linking assembly comprises a movable tower to which the first vertical arm is secured, and wherein the at least one roller is rotatably mounted on the movable tower. 10. The wheelchair lift of claim 9 wherein the movable tower defines a slot through which the at least one track extends.
