ABSTRACT:
An enclosure with doors contains a plurality of arched hoops or the like having ground engaging skids and with a flexible covering attached thereto. The hoops may be pulled out manually over a car or the like parked in front of the enclosure. Locking bars lock the hoops in spaced apart relationship automatically and a bar may be provided hooking under the bumper of the car for anchoring purposes. A winch in the enclosure winds cables passing through eyes on the hoops or arches and which are anchored to the outermost arch. Means are provided to break the over-center locking action of the locking bars as the hoops are wound in by the winch until the entire assembly is contained within the enclosure.
