Shielded cab for e.g. vehicle, has assembly of shape concordant units providing mutual support point that supports wall with respect to floor when external mechanical effort is applied to wall and floor

摘要

The cab (15) has curved walls, front walls (7a, 13), lateral walls (9a, 9b), and a rear wall (12) welded on a floor (1). The floor and one of the walls are assembled before welding by an assembly of shape concordant units between a lower edge of one of the walls and an external edge of the floor, where the shape concordant units are constituted of tabs (10) and slots (11). The assembly provides a mutual support point that supports the wall with respect to the floor when an external mechanical effort is applied to the wall and the floor.
