3. The expandable device of claim 2 , wherein the first end of the first elongated member is slidably and pivotably coupled to the first coupling portion.

4. The expandable device of claim 2 ,

wherein the linkage mechanism comprises a second elongated member having a first end and a second end, wherein the first end of the second elongated member is rotatably coupled to the second coupling portion, and wherein the second end of the second elongated member is rotatably coupled to the button, and

wherein the second ends of the first and second members each include a hooked portion, and the bottom side of the button comprises an opening to accommodate the hooked portions of the second ends of the first and second members.

5. The expandable device of claim 1 , wherein the linkage mechanism comprises a second elongated member having a first end and a second end, wherein the first end of the second elongated member is rotatably coupled to the second coupling portion, and wherein the second end of the second elongated member is rotatably coupled to the button.

6. The expandable device of claim 5 , wherein the first end of the second elongated member is slidably and pivotably coupled to the second coupling portion.

7. The expandable device of claim 1 , wherein the linkage mechanism is adapted to be nested in a region adjacent to the first coupling portion and the second coupling portion when the linkage mechanism is disposed in the first configuration.

8. The expandable device of claim 1 , wherein the linkage mechanism comprises three linkages.

9. The expandable device of claim 1 , wherein the linkage mechanism comprises four linkages.

10. The expandable device of claim 1 , further comprising a biasing device adapted to urge the button towards the second configuration.

11. The expandable device of claim 1 , wherein the first coupling portion comprises a slotted protrusion having an opening extending between a first end and a second end.

12. An expandable device for attachment to a portable electronic device, the expandable device comprising:

a base having a top side and a bottom side, the bottom side adapted to engage a portion of the portable electronic device or a case for the portable electronic device;

a first coupling portion disposed on the top side of the base;

a second coupling portion disposed on the top side of the base;

a linkage mechanism movably coupled to the first coupling portion and the second coupling portion; and

a button having a top side and a bottom side, the button being operably coupled to the linkage mechanism;

wherein the linkage mechanism is rotatable between a first configuration whereby the button is disposed in a collapsed configuration adjacent to the base, and a second configuration whereby the button is disposed in an expanded configuration spaced away from the base,

wherein the first coupling portion comprises a slotted protrusion having an opening extending between a first end and a second end.

13. The expandable device of claim 12 , wherein the linkage mechanism comprises a first elongated member having a first end and a second end, wherein the first end of the first elongated member is pivotably coupled to the first coupling portion, and wherein the second end of the first elongated member is pivotably coupled to the button.

14. The expandable device of claim 12 , wherein the first end of the first elongated member is slidably and pivotably coupled to the first coupling portion.

15. A method of operating an expandable device for a portable electronic device, the method comprising:

moving a linkage mechanism of the expandable device about pivot connections disposed on a base of the expandable device from a collapsed configuration to an expanded configuration whereby the linkage mechanism projects upwardly from the base; and

moving the linkage mechanism about the pivot connections from the expanded configuration to the collapsed configuration whereby the linkage mechanism generally extends along the base,

wherein moving the linkage mechanism comprises pivoting the linkage mechanism along a protrusion having an opening.

16. The method of claim 15 , wherein moving the linkage mechanism comprises pivoting the linkage mechanism along a slotted protrusion having an opening extending between a first end and a second end.

17. The method of claim 15 , further comprising biasing the linkage mechanism to the expanded states with a biasing mechanism.
