Abstract:
1. A temporary bridge comprising: two spans, in a non-deployed position, each of the two spans is separate and spaced apart from the other span, each of the two spans comprising at least first, second, and third bridge elements articulated to one another, said second bridge element being consecutive with said first bridge element and located below the first bridge element, said third bridge element being consecutive with the second bridge element and located below the second bridge element, each of said bridge elements having a first lateral edge and an opposite second lateral edge, wherein, when in the non-deployed position, said bridge elements are vertically superposed one located on top of another, two linking arms located on the first lateral edge of said first and second bridge elements and joining together said first and second bridge elements, wherein, the first and second bridge elements joined by the two linking arms form a deformable regular parallelogram such that movement of the first bridge element with respect to the second bridge element immediately below from said non-deployed position is a circular translational movement of said first bridge element with respect to said second bridge element wherein, a first of said two linking arms is common to each of said first, second, and third bridge elements, said first, second, and third bridge elements being connected to one another by said first linking arm, and a movement element that moves each of said first, second, and third bridge elements from said non-deployed position, in which said first, second, and third bridge elements are vertically superposed one located on top of another, to a deployed position with each of said first, second, and third bridge elements being linearly coupled together in a straight line to form said bridge.
