Abstract
A shelter has a rear stationary portion and a front retractable door, both on a base. The retractable door comprises nesting arcuate-roofed panels that cooperate to form an enclosing dome-like structure when closed. Moisture drainage and abatement strategies assist in keeping the shelter usable for long periods in exposed environments. Mechanical spring-biased assistance aids in both opening and closing the nested panels, resulting in a shelter that is easy to deploy and suitable for long term use.
