Lying element structure for use as e.g. back pack, has semi-cradles oriented on sides of central cradle and secured at cradle by rails to form frame defining lying surface, where frame is adapted to profile of ground during deformation

摘要

The structure has a central cradle (3) formed of tubular elements and semi-cradles (4, 5) associated to the cradle in reduced encumbrance or lying position. The semi-cradles are superimposed at the central cradle for forming a transportable volume such as backpack in the reduced encumbrance position. The semi-cradles are oriented on both sides of the central cradle and secured at the cradle by side rails (9) for forming a deformable raised frame defining a lying surface. The frame is adapted to the profile of the ground during deformation, where the structure remains on the structure.
