    • 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.
    • 轨道组件包括顶板204,其包括轨道206。 在图18中,已经添加虚线以示出用作辊214的轨道206的顶板204的部分。辊214和轨道216的相互作用类似于过山车轮及其相关轨道的相互作用。 在操作中,小的垂直辊214c抵靠顶板204的侧边缘(如可以在图17a和30a中看到的那样),小的水平辊214b抵靠顶板204的下侧(如在图30a中可以看到的那样) ),并且大水平辊214a骑在顶板204的顶部(如在图30a中可以看到的那样)。 这允许移动塔202从轨道组件200的一端行进到另一端。 如上所述,当平台13被折叠并拉动第一垂直臂42,并且因此将移动塔202向内拉动时,这种滚动运动发生。
