Abstract
Abstract Suitcase comprising two shells (1,2) assembled on one side by a hinge and on the other side by gripping (5,5') (6,6') and lockable closure means. One of the edges (10) perpendicular to the hinge is provided with rolling means (11,12) allowing to move it into two different positions, one of them being almost flat so that the side faces are strongly tilted relative to the rolling plane, the other position being such that the suitcase may almost rest edgewise. Rollers (11,12,21,22) are sunk into alveolus (12,13) containing a support (14) for the axis (15) of said roller. These supports (14) may be separated from the alveolus (13) by pushing on the small tongues (140). The suitcase comprises two handles (5,6) of which at least one allows to hold it on the rollers thereof. The handle (5,6) pivots about two axes (52) set into the side walls of the housing (50); each of the ends of the branches (53,54) comprises a boss (530,540 ) which fits into a corresponding recess of the housing (50). The folded handle is fully contained in the housing therefore, and in the turned up position it abuts against the wall (51).
