  • Patent number: 8267294
    Abstract: A method and apparatus for supporting a personal electronic device are provided. The device incorporates a support frame structure comprised of three legs. A vertical leg is attached to a shoulder strap, while the horizontal legs are attached to a chest strap. A lower joint is located between the two horizontal legs and this lower joint is also attached to an electronic device support leg. The electronic device support leg is attached to the lower joint and also to a ball joint at the end opposite the lower joint. In use, the lower joint allows for the electronic device to be moved into a viewing position at a desired angle. The ball joint allows rotation of the device between portrait and landscape orientations. A case may also be attached to the electronic device support leg to contain the personal electronic device.

  • Publication number: 20110305504
    Abstract: A friction ball joint and a method for using the friction ball joint are provided. A clam shell is formed from at least two segments and has a mechanical element extending from one of the clam shell segments. A cap that has a mechanical element extending from the rounded portion of the cap is also provided. This cap covers the joined clam shell segments opposite the mechanical element extending from the clam shell. The clam shell surrounds a spring that pushes the cap against the fixed outer clam shell, creating friction that retains the friction ball joint in the desired position. Further embodiments provide a locking assembly and an external spring or clamp. In these embodiments the spring or clamp is placed over the outside of the ball and clam shell. The ball has holes disposed over its surface to receive a locking assembly to hold the ball joint in the selected position.
