  • Convertible suitcase to be transformed into a seating or lying piece of furniture
    Patent number: 4742900
    Abstract: The suitcase (10) comprises two suitcase shells (12,14) which are hingedly connected to each other and adapted to be locked in folded condition. The suitcase (10) houses a head portion (16) and a foot portion (18) which are pivotably connected by double-joint hinges (22 and 24, respectively) to a narrow sidewall of the lower suitcase shell (12) such that they can be unfolded into a position for use when the suitcase is open. The two suitcase shells (12,14) can be folded together and locked even in this position for use. When the suitcase (10) is closed, the upper outside surface of the upper suitcase shell (14) presents a surface (20) to sit or lie on. The unfolded head and/or foot portion (16,18) is prevented from being swung back up to close to the lying surface (20) by an abutment surface (26,28) formed at the upper suitcase shell (14).
