Abstract

A case for a portable electronic device, the portable electronic device having a housing that carries a first magnetic element capable of forming a first magnetic circuit through the housing with a magnetic element external to the portable electronic device capable of securing together the housing and the external magnetic element. The case can include a body having a bottom wall and side walls that combine to define a recessed region suitable for retaining the portable electronic device and a second magnetic element located at a position corresponding to the external magnetic element such that when the portable electronic device is carried in the recessed region, the second magnetic element forms a second magnetic circuit through the body with the external magnetic element that is capable of securing together the case and the external magnetic element.

First claim

What is claimed is:

1. A case assembly for a portable electronic device having a first magnetic element, the case assembly comprising:
a case body having a bottom wall and side walls that combine to define a recessed region wherein the side walls assist in securing the portable electronic device within the recessed region; and
a flap pivotally coupled to the portable electronic device and comprising a second magnetic element, wherein when the portable electronic device is secured within the recessed region, and when substantially all of an exterior surface of the flap is in contact with a rear surface of the case body in an open configuration, the first magnetic element and the second magnetic element form a magnetic circuit through the case body, the magnetic circuit securing the flap with respect to the case body.

2. The case assembly of claim 1 , wherein the case body comprises a third magnetic element arranged such that when the flap is in the open configuration the first magnetic element and the third magnetic element form a second magnetic circuit that secures the flap to the case body.

3. The case assembly of claim 2 , wherein the third magnetic element is a magnet and the first magnetic element of the portable electronic device is a ferromagnetic material.

4. The case assembly of claim 2 , wherein the third magnetic element is comprised of at least two pieces.

5. The case assembly of claim 2 , wherein the second and third magnetic elements are arranged in a location that prevents damage by second and third magnetic elements to internal operational components of the portable electronic device.

6. The case assembly of claim 4 , wherein the at least two pieces of the third magnetic element are of different sizes.

7. The case assembly of claim 1 , wherein the second magnetic element is a magnet with a first polarity arrangement and the first magnetic element of the portable electronic device is a magnet with a second polarity arrangement that is complementary to the first polarity arrangement.

8. The case assembly of claim 1 , wherein the flap comprises panels, the panels being foldable onto each other.

9. The case assembly of claim 8 , wherein the panels comprise a first, second middle and third panel and the first magnetic element is located in the second middle panel.

10. A portable electronic device cover comprising:
a magnetic attachment mechanism; and
a single piece flap attached to the magnetic attachment mechanism, the single piece flap carrying a magnet, wherein when the magnetic attachment mechanism magnetically attaches to a portable electronic device having a processor in communication with a magnetic sensor, and the single piece flap is in an open configuration where the single piece flap is positioned with respect to the portable electronic device such that substantially all of an exterior surface of the flap is in contact with a rear surface of the portable electronic device, the sensor is capable of detecting the magnet and providing a detection signal to the processor that, in turn, alters an operation of the portable electronic device.

11. The portable electronic device cover of claim 10 , wherein the magnet carried by the flap is configured to cooperate with a magnetic element arranged in a case secured to the portable electronic device to complete a magnetic circuit that restrains substantially all of the exterior surface of the cover to the case in the open configuration.

12. The portable electronic device cover of claim 11 , wherein the magnet carried by the flap comprises at least two magnets having different sizes.

13. The portable electronic device cover of claim 11 , wherein the magnet carried by the flap comprises at least two magnets having different shapes.

14. The portable electronic device cover of claim 10 , wherein the portable electronic device further comprises an internal magnet and wherein the magnet carried by the flap coordinates with the internal magnet to restrain the flap against the portable electronic device in the open configuration.

15. The portable electronic device cover of claim 10 , wherein the cover further comprises a first, second middle and third panel that are foldable upon each other and the magnet is located in the second middle panel.

16. The portable electronic device cover of claim 10 , wherein the signal provided to the processor is used to turn the portable electronic device on.
