Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 155 words
For a water flume adapted to carry a stream of water in which passenger carrying vessels float and are carried thereby, a plurality of flume sections adapted to be connected together in order to form the water flume, each section comprising a fiberglass trough structure having a floor with opposing walls integrally formed therewith by fiberglass extending upward therefrom along its sides, both ends of said section having a given shaped opening for mating together with other of said sections to form the flume, an underside of the floor containing at least one structural beam extending along a significant portion of its length and at least one other structural beam extending across the underside of the floor and up the sides outside said trough, each of said beams being formed of fiberglass walls integrally with the section floor and sides and rectangular in cross-section with a non-structural material in a space enclosed by said walls.
Claim 2
Dependent Claim 155 words
For a water flume adapted to carry a stream of water in which passenger carrying vessels float and are carried thereby, a plurality of flume sections adapted to be connected together in order to form the water flume, each section comprising a fiberglass trough structure having a floor with opposing walls integrally formed therewith by fiberglass extending upward therefrom along its sides, both ends of said section having a given shaped opening for mating together with other of said sections to form the flume, an underside of the floor containing at least one structural beam extending along a significant portion of its length and at least one other structural beam extending across the underside of the floor and up the sides outside said trough, each of said beams being formed of fiberglass walls integrally with the section floor and sides and rectangular in cross-section with a non-structural material in a space enclosed by said walls.
Claim 3
Dependent Claim 84 words

Claim 4
Dependent Claim 13 words
The structure according to claim 1 wherein said non-structural material is foam plastic.
Claim 5
Dependent Claim 27 words
The structure according to claim 1 wherein one of said walls of each of said beams includes a portion of the floor or side of the trough.
Claim 6
Dependent Claim 39 words
The structure according to any of claims 1, 3 or 4 wherein said at least one beam along the length of the trough and said at least one beam across the trough cross each other in an integrated structure.
