  • the method 1200 commences at step 1201 by rotating the chassis 1110 such that the chassis 1110 laterally aligns with the first floater 1130.
  • the chassis 1110 is first unlocked from the axial crevices 1130cle of the first floater 1130. Thereafter, the chassis 1110 is rotated about the pivot structure to align the chassis 1110 laterally to the first floater 1130 such that the chassis 1110 is locked with the lateral crevices 1130cld of the first floater 1130.
  • the unit 1100 may be toggled from the third configuration to the first configuration.
  • the units 1100 are placed one after the other such that the extreme ends 1113c of one unit 1100 faces the extreme end 1113c of a consecutively placed unit 1100.
  • the units 1100 are aligned and consecutively coupled to each other via the alignment means 1119 and coupling means 1117 (described above).
  • the supports may be coupled to at least one of the chassis 1110 or the first floater 1130.
  • the support is coupled to the first floaters 1130 of the units 1100.
  • the resultant bridge obtained by coupling the units 1100 may be deployed across the inland water body such that the users of the bridge are enabled to cross the inland water body safely.

Abstract

La présente divulgation divulgue une unité (100, 1100) permettant de traverser des masses d'eaux intérieures. Une ou plusieurs unités (100, 1100) sont configurées pour former un pont de longueur personnalisable. L'unité (100, 1100) comprend au moins un premier flotteur (130, 1130), et au moins un châssis (110, 1110). Le premier flotteur (130, 1130) comprend au moins une fente centrale (130c1c, 1130c1c). Le premier flotteur (130, 1130) est configuré pour flotter sur l'eau. Le châssis (110, 1110) est accouplé à la fente centrale (130c1c, 1130c1c) du premier flotteur (130, 1130) par l'intermédiaire d'une structure de pivot (111b4). L'unité (100, 1100) est configurée pour être basculée entre au moins une première configuration et une troisième configuration. Dans la première configuration, le châssis (110, 1110) est aligné latéralement avec le premier flotteur (130, 1130). Dans la troisième configuration, le châssis (110, 1110) est aligné axialement avec le premier flotteur (130, 1130).
