  • Patent number: 7678029
    Abstract: An inflatable punching bag includes an inflatable bag, at least one sensor device, a control box and a base. At least one impact area is formed on the inflatable bag. A single sensor device is attached behind each impact area. Each sensor device preferably includes a sensor case, at least one light source and an impact sensor. A control box includes a power source, a sound transducer and an electrical circuit. The electrical circuit receives input from at least one impact sensor. The electrical circuit provides a light output through the at least one light source and/or an audible output through the sound transducer. The base preferably includes a weighted portion and intermediate portion. The weighted portion is filled with a dense solid or a liquid to provide support for the inflatable bag. A second embodiment includes a motor for pivoting the inflatable bag.

The electrical circuit provides a light output through the at least one light source, an audible output through the sound transducer and a video output through a video display. The base preferably includes a weighted portion and intermediate portion. The weighted portion is filled with a dense solid or liquid to provide radial support for the inflatable punching bag. The intermediate portion is disposed between the base and the inflatable bag.
