Abstract
An internal frame for supporting a wheeled suitcase comprises a base, a U-shaped frame mounted on top of the base and a central frame comprising a horizontal U-shaped member having two legs on its rear end and two vertical elongated supporting members. The top ends of the two supporting members are connected to the rear ends of the two legs of the U-shaped member. The upper end of the central frame is mounted to the central part of the top panel of the U-shaped frame and the lower end of the central frame is mounted to the bottom panel of the base so that the structure of the internal frame is greatly strengthened by the central frame.
