Abstract
The present invention pertains to a portable motorized suitcase which can operate in either self-propelled or manual modes. The suitcase includes an extendable handle which is provided with a multi-position switch, allowing the user to selectively control the speed of the suitcase when in the self-propelled mode, as well as allowing the user to choose between modes of operation. A motor, which is controlled by the multi-position switch located on an extendable handle, conveys power to the ground engaging wheel via a centrifugal clutch arrangement. The clutch allows the motor to propel the suitcase when it is in the self-propelling mode while not hindering the rolling of the wheels when the motor is in the manual mode. Therefore, the motor and clutch arrangement either turns the wheels or allows them to free-wheel, depending upon the operator's positioning of the multi-position switch. Transition between modes of operation occurs automatically in accordance with user manipulation of the switch. The motor is supplied with power from a removable battery pack. The rear wheels of the suitcase, one of which is selectively driven by the motor, are outwardly spaced from the sidewalls of the suitcase to stably support the suitcase during movement thereof.
