Abstract
Abstract Amphibious vehicle adapted for use as a ferry or a bridge unit with a vehicle body in the form of a floating unit having auxiliary floating members at its longitudinal sides which can be blown up and swung outwardly, and ramps linked to both ends of the body that have a pivot joint centrally with respect to the length thereof, where the ramps are also in the form of buoyant hollow bodies and which, when unfolded, are of a length corresponding to the length of the vehicle and when folded are shortened to one-half the length, and are equipped with coupling means at the end surfaces thus established, where furthermore loose planks are arranged on the vehicle the length of which corresponds to half the length of the vehicle and thereby also to the length of the folded ramps, and the width of which corresponds to the width of the lateral auxiliary floating members in blown up or unfolded condition, and where associated retaining and connecting means are provided on the vehicle, the ramps and the auxiliary floating members on the one hand and on the planks on the other hand.

Total Claims: 6
Claim 1
Independent Claim
204 words
Amphibious vehicle for deployment as ferry or bridge vehicle comprising a buoyant vehicle body having a deck surface, inflatable and unfoldable auxiliary floating bodies disposed along the longitudinal sides of said vehicle body and buoyant end ramps linked to both ends of said vehicle body which as related to their length are provided with a central folding joint, said ramps being in the form of buoyant hollow bodies each having a length when unfolded corresponding to the length of the vehicle body and when folded being shortened to half the length and having a surface proximate said deck surface, and presenting adjacent end surfaces, coupling means on said end surfaces, loose planks associated with said vehicle, the length of said planks corresponding to the length of the folded ramps and the width of said planks corresponding to the width in expanded condition of the buoyant hollow bodies that otherwise disappear in the sidewalls of the buoyant vehicle body, and coordinated supporting and connecting means provided on the vehicle body, the ramps and the auxiliary floating bodies on the one hand and on the other hand on the planks, said vehicle furthermore comprising connecting means, permitting coupling together said buoyant end ramps in overlapping positions.
Claim 2
Dependent Claim
