20120090250 | Retractable Enclosure - Described herein is a retractable enclosure that includes a sequence of upright arches, such that the arches are substantially parallel and such that the two ends of each upright arch are disposed on a base. The arches are configured to leave a gap between adjacent arches. The retractable enclosure also includes a plurality of extendable covers attached to the arches such that at least one extendable cover is disposed between adjacent arches and such that each extendable cover can assume an extended state and a retracted state. The gap between adjacent arches can be mostly closed when the at least one extendible cover therebetween is in its extended state. | 04-19-2012 |
