ABSTRACT:
An extendible and retractable shelter for a vehicle has a plurality of bows slidable along a pair of ground mounted tracks from an extended position to a retracted position. A flexible canvas or plastic covering is attached to the bows when extended and collapses in accordion fashion when retracted. A lazy tongs mechanism is attached to the interior faces of the bows and are loaded by tension springs. The bows are retracted by a cable and winch system, placing the springs under tension and locked by a ratchet lock. When the lock is released, the tension springs return the bows to the extended position.
