Abstract
Abstract A collapsible and portable shelter for the nose of an aircraft including a toroidal section supported on U-shaped bows, the outer ends of which are pivoted for an erecting and collapsing action basically similar to the action of a perambulator hood. The legs of the bows are hinged near the bight portions of the bows so they can be folded inwardly when the structure is collapsed to form a compact bundle. The bow at one end of the structure is mounted on casters for easy maneuverability when the structure is collapsed. Straight vertical sections may be secured to the toroidal section to extend the dock to any desired length.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
181 words
An aircraft nose dock comprising plural rigid bows of substantially identical construction, the legs of said bows being hinged to permit them to be folded inwardly towards each other and across the bight portions of said bows, means pivoting the ends of the legs of said bows about a common axis when said legs are straight and unfolded, said pivot means being arranged so that when said bows are pivoted towards each other they lie in flat stacked noninterfering registered array, a base bow generally similar to the aforesaid bows and mounting said pivot means, casters mounted on said base bow to support it movably upon a surface such as the ground or a roadway, and an extendable section secured to the one of said bows farthest from said base bow and extendable therefrom when said bows are extended to form a tunnellike extension joined to the toroidal section formed by said bows, said extendable section also including supporting bows identical to the first said bows so that the entire structure may be collapsed in stacked array upon said base bow.
