Method and apparatus for portable device accessories

1. An apparatus comprising:

an accessory device;

two user separable and joinable clips;

a retractable clip tensioner; and

an accessory device holder mechanically inter-connecting the accessory device with the retractable clip tensioner, wherein the retractable clip tensioner connects each of the two user separable and joinable clips to the accessory device holder,

wherein, the retractable clip tensioner enables a user to attach the apparatus against a first side of a portable electronic device by expanding and engaging the clips against different other sides of the portable electronic device so that the retractable clip tensioner maintains the clips engaged;

wherein, when the clips are connected to each other in a closed configuration, the clips collectively form a storage space containing the accessory device therein, and wherein the clips form a closed exterior surface covering a majority of a front face of the accessory device.

2. The apparatus of claim 1 , wherein the accessory device holder enables adjustable attachment of the accessory device to the retractable clip tensioner.

3. The apparatus of claim 2 , wherein the accessory device holder comprises channels along both sides of the accessory device holder, and wherein the retractable clip tensioner slides through the channels of the accessory device holder to enable the adjustable attachment of the accessory device to the retractable clip tensioner.

4. The apparatus of claim 1 , wherein the accessory device is configured to co-operate with the portable electronic device.

5. The apparatus of claim 4 , wherein the accessory device is a camera accessory that co-operates with a camera lens of the portable electronic device.

6. The apparatus of claim 1 , wherein at least one of the retractable clip tensioner and the accessory device is configured to enable adjustable attachment of the accessory device to the retractable clip tensioner.

7. The apparatus of claim 1 , wherein the clips comprise concave forms configured to sandwich the portable electronic device when the clips are separated and engaged against the different other sides of the portable electronic device.

8. The apparatus of claim 1 , wherein the retractable clip tensioner comprises an elastic band.

9. The apparatus of claim 1 , further configured to enable user adjustable positioning of the accessory device at different positions of the retractable clip tensioner.

10. The apparatus of claim 1 , further configured to enable attaching the accessory device at adjustable distance from the portable electronic device.

11. The apparatus of claim 1 , wherein the accessory device holder comprises one or more user replaceable accessory devices.

12. The apparatus of claim 1 , wherein any one or more of the clips is formed of plastics; metal; composite material; glass; rubber; or any combination thereof.

13. The apparatus of claim 1 , wherein one or more of the clips comprises a space for a key or button on the respective different other side of the portable electronic device to avoid undesirably acting on the key or button when the one or more of the clips is engaged against the respective different other side of the portable electronic device at the key or button.

14. The apparatus of claim 1 , further configured to enable attaching the portable electronic device to another object.

15. The apparatus of claim 1 , wherein the portable electronic device is at least one of: a mobile telephone; a personal digital assistant; a digital camera; a tablet computer; a laptop computer; a game device; or a navigation device.

16. The apparatus of claim 1 , wherein each of the two user separable and joinable clips have a ‘C’ shaped or ‘J’ shaped profile, wherein concave sides of the two clips are inwardly facing.

17. A system comprising the apparatus of claim 1 and the portable electronic device.

18. An apparatus comprising:

an accessory device,

two user separable and joinable clips; and

a retractable clip tensioner; and

an accessory device holder mechanically inter-connecting the accessory device with the retractable clip tensioner, wherein the retractable clip tensioner connects each of the two user separable and joinable clips to the accessory device holder, and wherein the retractable clip tensioner enables a user to attach the apparatus against a first side of an electronic portable device by expanding and engaging the clips against different other sides of the portable electronic device so that the retractable clip tensioner maintains the clips engaged;

wherein, when the clips are connected to each other in a closed configuration, the clips collectively form, when joined, a storage space for the accessory device, and wherein the accessory device comprises one or more items selected from a group consisting of: an objective; an optical filter; a neutral density filter; a gradient filter; a polarizing filter; a light guide for passing flash light; a mirror or prism for guiding flash light; optically transparent gel for facilitating objective tilting; an objective cover; a sun glare protector; a touch screen stylus; a spare part for the retractable clip tensioner; an input device; and a joystick.
