Abstract
A wheeled transport device, such as a piece of luggage configured to be manually wheeled by a pedestrian user, in provided with an electrical generator operably coupled to a rolling wheel of the device and configured to produce electrical energy as the user wheels the device along a supporting surface. The generator provides power to charge a battery contained within the device and/or one or more electrical appliances being transported within the device.
Claims28
A wheeled transport device configured to be manually wheeled by a pedestrian user, the transport device comprising:
- a main body defining a compartment therein for containing goods to be transported;
- a handle attached to the main body and manually graspable by the pedestrian user while walking;
- at least one wheel disposed at a lower end of the main body and secured to the body for rotation along a surface upon which the user is walking;
- an electrical generator operably coupled to the wheel and configured to produce electrical energy as the user wheels the device along the surface;
- and
- a battery secured to the main body and electrically connected to the generator for storage of electrical energy from the generator.
A method of powering personal electrical appliances, the method comprising:
- providing a wheeled transport device comprising:
- a main body defining a compartment therein for containing goods to be transported;
- a handle attached to the main body and manually graspable by the pedestrian user while walking;
- at least one wheel disposed at a lower end of the main body and secured to the body for rotation along a surface upon which the user is walking;
- and
- an electrical generator operably coupled to the wheel and configured to produce electrical energy as the user wheels the device along the surface;
- electrically connecting a personal electrical appliance to the generator of the device;
- and
- rolling the device along a surface to generate and deliver electrical power to the connected appliance.
A wheeled transport device configured to be manually wheeled by a pedestrian user, the transport device comprising:
- a main body compartment therein for containing goods to be transported;
- a handle attached to the main body and manually grasp able by the pedestrian user while walking;
- at least one wheel disposed at a lower end of the main body and secured to the body for rotation along a surface upon which the user is walking;
- an electrical generator operably coupled to the wheel and configured to produce electrical energy as the user wheels the device along the surface;
- and
- an electrical power outlet secured to the main body, electrically connected to the generator, and exposed for connection of an electrically powered device by the user.
A wheeled transport device in combination with a personal electrical appliance, the transport device configured to be manually wheeled by a pedestrian user and comprising:
- a main body defining a compartment therein for goods to be transported;
- a handle attached to the main body and manually graspable by the pedestrian user while walking;
- at least one wheel disposed at a lower end of the main body and secured to the body for rotation along a surface upon which the user is walking;
- and
- an electrical generator operably coupled to the wheel and configured to produce electrical energy as the user wheels the device along the surface;
- wherein the personal electrical appliance is contained within the compartment and is electrically connected to the generator.
