Abstract
Abstract An amphibious vehicle adapted particularly as a part of a floating bridge but also deployable as a ferry having a runway portion pivotably movable about a vertical axis which at one end is formed as a ramp pivotable relative to the remaining part of the runway about a horizontal axis extending transversely of the direction of travel, where this ramp is subdivided centrally about a horizontal axis that extends again transversely of the runway about which the outer free half of the ramp can be folded under the inner half thereof and the front end of the runway section thus formed is adapted to be coupled to the corresponding front end of the runway section of an adjacent amphibious vehicle and where the vehicle section pivotable about a vertical axis is also constructed at its other end as a ramp constructed in this manner.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
203 words
An amphibious vehicle, particularly for putting together floating bridges and for deployment as ferry comprising an amphibious vehicle body, a vertically disposed pivot element mounted on said vehicle body, a runway structure comprising a pair of ramp sections extending transversely of said pivot member in opposite directions, each of said ramp sections being subdivided generally centrally between its ends into an inner and an associated outer portion; hinge means intermediate said pivot member and said inner ramp portions connecting the latter to said pivot member on first horizontal, transverse axes, respectively; power means intermediate said pivot member and said inner ramp portions for moving said inner ramp portions into different angular positions about said first horizontal transverse axes; hinge means interconnecting said inner ramp portions and their associated outer ramp portions on second horizontal transverse axes, respectively; and second power means intermediate each of said inner ramp portions and their associated outer ramp portions whereby said outer ramp portions are movable to different angular positions relative to and are foldable under said inner ramp portions, respectively; said folded portions defining proximate said second transverse axes coupling ends adapted to be coupled with a corresponding coupling end of the runway structure of another vehicle.
Claim 2
Dependent Claim
203 words
An amphibious vehicle, particularly for putting together floating bridges and for deployment as ferry comprising an amphibious vehicle body, a vertically disposed pivot element mounted on said vehicle body, a runway structure comprising a pair of ramp sections extending transversely of said pivot member in opposite directions, each of said ramp sections being subdivided generally centrally between its ends into an inner and an associated outer portion; hinge means intermediate said pivot member and said inner ramp portions connecting the latter to said pivot member on first horizontal, transverse axes, respectively; power means intermediate said pivot member and said inner ramp portions for moving said inner ramp portions into different angular positions about said first horizontal transverse axes; hinge means interconnecting said inner ramp portions and their associated outer ramp portions on second horizontal transverse axes, respectively; and second power means intermediate each of said inner ramp portions and their associated outer ramp portions whereby said outer ramp portions are movable to different angular positions relative to and are foldable under said inner ramp portions, respectively; said folded portions defining proximate said second transverse axes coupling ends adapted to be coupled with a corresponding coupling end of the runway structure of another vehicle.
Claim 3
Dependent Claim
26 words
An amphibious vehicle as set forth in claim 1 and further comprising a runway portion extending over said pivot element and connecting said inner ramp portions.
Claim 4
Dependent Claim
50 words
An amphibious vehicle as set forth in claim 2 and further comprising lug means on said inner ramp portions and on their associated outer ramp portions adjacent said second horizontal axes, respectively, and associated bolt members for fixing said inner and outer ramp portions in predetermined positions of relative adjustment.
