Patent ID: 8181921

Claim:
A platform telescoping system, comprising: a platform; and a second supporting arm at least part of which is encased within a first supporting arm, wherein the platform is pivotally attached to the second supporting arm to pivot around a first axis, which is substantially parallel to a weight bearing surface of the platform, to a position that reduces a footprint of the platform telescoping system, and the first supporting arm encases at least the part of the second supporting arm to allow the second supporting arm to telescope in a first direction and to pivot around a first axis by using a telescopic driving mechanism and a rotational driving mechanism; a first linear track and a second linear track which is attached to at least one of the first supporting arm and the second supporting arm in the first direction; a track mounting seat which is attached to one of the first supporting arm and the second supporting arm that is not attached to the first linear track, wherein the first linear track and the track mounting seat move along a second direction with respect to each other; a clearance adjusting mechanism which is attached to one of the first supporting arm and the second supporting arm that is not attached to the second linear track, wherein the clearance adjusting mechanism comprises a first mounting shaft, a first adjustment wheel attached to the first mounting shaft; and a second adjustment wheel eccentrically attached to a second mounting shaft, wherein the first mounting shaft and the second mounting shaft are attached to their respective supporting arms, and the second linear track is situated between the first adjusting wheel and the second adjusting wheel.
