Abstract

Abstract The invention relates to a ramp section or assembly for a collapsible floating bridge or ferry. The ramp section comprises two inner and two part outer float elements, connected together by joints. The two parts of the float element are, according to the invention, composed of a pair of partial constant and partial transversely convering cross section and a pair movable relative to the part of partial constant and partial transversely converging cross section, which are pivotably connected by first joints. Through the first joint the movable part can be brought into aligned arrangement or juxtaposition with the part of constant cross section when picking up from or setting down on a transport vehicle, so that guiding by the rollers connected with the transport vehicle is achieved.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 181 words
A ramp section for a collapsible floating bridge and ferry, comprising two inner and two two-part outer float elements, said inner float elements being connected by pivot joints permitting pivoting of said two inner float elements relative to each other about a longitudinal axis, said inner float elements each having an outer side, each outer float element being pivotally connected with a respective outer side of a respective other of said inner float elements, each outer float element comprising a first part and a second part which is movable relative to said first part and of a longitudinally converging cross section, said second part being connected with said first part by first pivot joints in such a way that the axis of rotation of said first pivot joints is perpendicular to a direction of passage and said first part of the outer float elements being connected to said inner float elements by second joints in such a way that both of said first and second outer float elements can execute pivot movements about an axis parallel to the direction of passage.
Claim 2
Dependent Claim 181 words
A ramp section for a collapsible floating bridge and ferry, comprising two inner and two two-part outer float elements, said inner float elements being connected by pivot joints permitting pivoting of said two inner float elements relative to each other about a longitudinal axis, said inner float elements each having an outer side, each outer float element being pivotally connected with a respective outer side of a respective other of said inner float elements, each outer float element comprising a first part and a second part which is movable relative to said first part and of a longitudinally converging cross section, said second part being connected with said first part by first pivot joints in such a way that the axis of rotation of said first pivot joints is perpendicular to a direction of passage and said first part of the outer float elements being connected to said inner float elements by second joints in such a way that both of said first and second outer float elements can execute pivot movements about an axis parallel to the direction of passage.
Claim 3
Dependent Claim 31 words
A ramp section according to claim 1, wherein said pivot joints between said two inner float elements are arranged in a region of constant cross section of said inner float elements.
Claim 4
Dependent Claim 22 words
A ramp section according to claim 1, including a roller connected to an outer edge of each of said outer float elements.
Claim 5
Dependent Claim 29 words
A ramp section according to claim 1, wherein said inner float elements have a portion of constant cross section immediately adjacent to a portion of longitudinally converging cross section.
Claim 6
Dependent Claim 46 words
A ramp section according to claim 1, comprising a top deck level and a bottom deck level wherein said pivot joints between said first part and said second part are arranged at selected level, between and including said top deck level and said bottom deck level.
