Abstract

The present invention relates to a manually operable input apparatus (202) for a portable electronic processing device (102), such as a mobile phone or hand-held processor. The apparatus defines a plurality of regions (303, 304) each representing a respective data item and comprises a plurality of sheets configured to produce a response to a mechanical interaction. Furthermore, the sheets are configured to be wrapped around the device to provide a protective cover.

Claims

1. A manually operable input apparatus for a portable electronic processing device, defining a plurality of regions each representing a respective data item, said manually operable input apparatus comprising a plurality of sheets configured to produce a response to a mechanical interaction and a stand for supporting said electronic processing device;

wherein

said sheets are configured to be wrapped around said electronic processing device to provide a protective cover, and

said sheets are configured to be foldable through at least one of said plurality of regions;

said input apparatus comprises connecting means to connect said input apparatus to said electronic processing device, and

said connecting means is foldable to allow said input apparatus and said electronic processing device to be mutually arranged in an operational configuration in which said electronic processing device is supported in a position spaced apart from said input apparatus, and to be reconfigured into a wrapped configuration in which said electronic processing device is enveloped by said input apparatus, by the steps of

folding said connecting means about a first axis to an intermediate position in which said electronic processing device is received on a surface of said input apparatus, and

bending said input apparatus about a second axis non-parallel with said first axis and a third axis non-parallel with said first axis.

2. Apparatus according to claim 1, wherein said input apparatus is a keyboard.

3. Apparatus according to claim 2, wherein said input apparatus is constructed from fabric.

4. Apparatus according to claim 2, wherein said input apparatus comprises a membrane keyboard.

5. Apparatus according to claim 2, wherein said keyboard surface is configured so as to facilitate the bending of the keyboard.

6. Apparatus according to claim 1, wherein said processing device is a hand-held computer, a mobile telephone or portable audio equipment.

7. Apparatus according to claim 1, wherein said connecting means further comprises an interface circuit configured to apply voltages to one or more of said sheets and to convey positional data to said electronic processing device.

8. Apparatus according to claim 7 wherein said electronic processing device is programmed to correlate said positional data with look up tables for converting positional data received from said interface circuit into a presentation in form of alpha numeric text.

9. Apparatus according to claim 1, wherein said connecting means is configured so as to retain said electronic processing device connected thereto during bending operations.

10. Apparatus according to claim 1, wherein said connecting means is configured so as to retain said electronic processing device connected thereto during folding operations.

11. Apparatus according to claim 1, wherein said second axis and third axis are disposed in a substantially parallel relationship to one another.

12. Apparatus according to claim 1 wherein said second bending axis and said third bending axis divide the input apparatus into a central portion, a first lateral substantially planar portion and a second lateral substantially planar portion.

13. Apparatus according to claim 12 wherein, in the intermediate position said electronic processing device is received by said central portion and said first lateral portion bends about a first edge of said electronic processing device along said second axis and said second portion extends about a second edge of said electronic processing device along said third axis to form said wrapped configuration.

14. Apparatus according to claim 13, wherein said first lateral portion and said second lateral portion of said input apparatus are secure in the wrapped configuration by a securing means.

15. Apparatus according to claim 14, wherein said securing means is a hook and loop fastening system such as VELCRO®

.

16. Apparatus according to claim 1, wherein in said intermediate position, said electronic processing device is operable independently of said input apparatus.

17. Apparatus according to claim 1, wherein said electronic processing device is supported by said stand in said operational configuration.

18. Apparatus according to claim 17, wherein said stand comprises a flexible fabric cable having electrical connection elements contained therein.

19. Apparatus according to claim 18, wherein said stand comprises hinged support portions to facilitate the erection of said stand.

20. Apparatus according to claim 19, wherein said sections of plastic hinge about said flexible fabric cable.

21. Apparatus according to claim 1 and a portable electronic processing device in combination wherein said input apparatus is permanently attached to an edge of said electronic processing device and is configured to allow mutually arrangement in an operable configuration, in which the input apparatus extends from said edge of said electronic processing device, and reconfiguration into the wrapped configuration in which said input apparatus is wrapped around said electronic processing device.
