MOBILE CROSSING STRUCTURE
A movable and dynamic work after construction linking two points separated by a natural or man-made obstacle, allows the permanent crossing of this obstacle. The work includes a deformable apron (1) which extends between said two points, a set of elongated elements (2, 3), having three openings (5A, 5A′, 5B), a first opening (5A, 5A′) at each end of the elements (2, 3) and a second intermediate opening (5B) disposed between the first two openings (5A, 5A′) present at the ends of the elements (2, 3), said openings (5, 5A, 5A′) receiving ball joints for forming hinges (4), each element (2, 3) consisting of a first short portion between a first opening (5A) and the intermediate opening (5B) and of a second longer portion between the other first opening (5A′) and the intermediate opening (5B), the elements (2, 3) being disposed in pairs, movable in rotation, around a central hinge (4) constituted by a ball joint in the intermediate openings (5B) of two elements (2, 3). An assembly of several pairs of elements (2, 3) made by ball inserted into the openings (5A, 5A′) disposed at the ends of each element (2, 3), is disposed along the apron (1), on one side or on both sides of the apron (1) in a plane substantially perpendicular to the axis of said hinges (4) and allowing a relative movement of the elements (2, 3) from a first position to a second position having place in said plane perpendicular to the axis of the hinges (4). Drive means (8) are disposed at one end or at both ends of said work for adjusting the apron (1) lengthwise. The work includes drive means (8) arranged so that, when the means (8) are actuated, they drive the assembly of the pairs of elements (2, 3), said short portions of the elements (2, 3) being disposed on the upper portion of the pairs of elements (2, 3) disposed at the ends of the work while said short portions of the elements (2, 3) are disposed on the lower portion of the pairs of elements (2, 3) disposed towards the center of the work, so as to bulge the central portion of the apron (1) when the means (8) are actuated.
