ABSTRACT:
The track assembly includes top plate204,which incorporates the tracks206. In FIG.18, dashed lines have been added to show the portion of the top plate204that is used as the track206for the rollers214. The interaction of the rollers214and track216is similar to the interaction of rollercoaster wheels and their associated track. In operation, small vertical rollers214cride against the side edge of top plate204(as can be seen in FIGS.17aand30a), small horizontal rollers214bride against the underside of top plate204(as can be seen in FIG.30a), and the large horizontal roller214arides on the top of top plate204(as can be seen in FIG.30a). This allows the moving tower202to travel from one end of the track assembly200to the other. As is described above, this rolling movement takes place when the platform13is folded and pulls the first vertical arm42, and, therefore, the moving tower202inwardly.
