  • Patent number: 7641046
    Abstract: Combination case for providing a versatile protective case for a handheld device, such as a PDA. The combination case has a rigid inner shell that attaches to an outer shell with a mounting plate. The handheld device is inserted into the rigid inner shell, which is then attached to the rear panel of the outer shell. The rigid inner shell is a three-sided shell that holds the handheld device and allows free access to the LCD display and operational components on the device when the outer shell is open. A soft inner shell may be used instead of the rigid inner shell. This soft inner shell attaches to the outer shell with the mounting plate and provides a water-resistant enclosure for the device.
