Abstract
An apparatus (1) that can be converted into an air cushion support or into an air cushion support for a vehicle (3). This apparatus can be folded into a compact container or put onto its own wheels (2) permitting it to be hauled as a trailer. The apparatus comprises a latticed folding base composed of hingedly connected main sections (10) and perimeter sections (11-14), a flexible inflatable air cushion skirt (5) and coupling means (8,9) for coupling the vehicle (3) to the main sections of the base, to propulsion and blowing means (6) and to a steering gear mechanism (7). The lower surface of latticed sections is covered by elastic airtight sheet material (33,34) which forms a chamber (35) of the flexible inflatable skirt and an air cushion chamber (37). Longitudinal (19) and transverse (20) girders of main sections of the base are connected by elastic and resilient coupling elements (21) permitting limited displacements of these girders against each other and thus giving to the base the capability of matching, to a certain extent, a given terrain contour when the apparatus is converted into an air cushion support and used as a vehicle for travel.
