Abstract

An apparatus including a first housing section; a second housing section rotatably connected to the first housing section between a closed position and an open position; and an opening system. The opening system is connected between the first and second housing sections and configured to move the second housing section relative to the first housing section towards the open position. The opening system includes a flexible thin foil and a tension spring. The tension spring exerts a pulling force against the foil.

Claims

1. An apparatus comprising:

a first housing section;

a second housing section rotatably connected to the first housing section between a closed position and an open position; and

an opening system connected between the first and second housing sections and configured to move the second housing section relative to the first housing section towards the open position, wherein the opening system comprises a flexible thin foil and a tension spring, and wherein the tension spring exerts a pulling force on the foil.

2. An apparatus as in claim 1 wherein a first end of the foil is connected to the second housing section, wherein a second end of the foil is connected to a first end of the tension spring, and wherein a second end of the tension spring is connected to the first housing section.

3. An apparatus as in claim 1 wherein the foil extends over an exterior side of a joint between the first and second housing sections when the housing sections are in both the open position and the closed position.

4. An apparatus as in claim 1 wherein a connection of the first housing section to the second housing section comprises a pivotable hinge section.

5. An apparatus as in claim 4 wherein the spring is located inside a cavity in the first housing section spaced from the pivotable hinge section.

6. An apparatus as in claim 4 wherein the foil extends over an exterior of the hinge section and at least partially along exterior sides of the first and second housing sections.

7. An apparatus as in claim 6 further comprising a flexible flat printed circuit cable located against an interior side of the foil, wherein the flexible flat printed circuit cable extends over the exterior of the hinge section.

8. An apparatus as in claim 1 wherein the foil is comprised of metal.

9. An apparatus as in claim 1 wherein the foil comprises of a superelastic material.

10. An apparatus as in claim 1 wherein the foil has a width about a same width as the second housing section.

11. An apparatus as in claim 1 wherein the foil has a length which is greater than a length of the first housing section and greater than a length of the second housing section.

12. An apparatus as in claim 1 wherein the spring comprises a coil spring.

13. An apparatus as in claim 1 wherein the spring comprises at least two spaced springs connected to an end of the foil.

14. An apparatus as in claim 1 wherein an exterior of the foil comprises plated or engraved decoration.

15. An apparatus as in claim 14 wherein the foil is removably connected to the first and second housing sections such that an end user can replace the foil with a second different foil having a different plated or engraved decoration on the exterior of the second foil.

16. An apparatus as in claim 1 wherein the spring comprises an extension and contraction axis parallel to an elongate longitudinal axis of the first housing section.

17. An apparatus as in claim 1 wherein the apparatus is a mobile, hand-held communications device comprising a transceiver and a display screen.

18. An apparatus comprising:

a first housing section;

a second housing section pivotably connected to the first housing section at a hinge section, wherein the second housing section is pivotable relative to the first housing section between a closed position and an open position;

a flexible thin sheet member extending between the first and second housing sections over an exterior of the hinge section, wherein the sheet member is located at least partially along outside surfaces of the first and second housing sections, and wherein a first end of the sheet member is stationarily attached to the second housing section; and

a connection of the sheet member to the first housing section, wherein the connection comprises a spring connected between the first housing section and an opposite second end of the sheet member, wherein the spring exerts a pulling force on the second end of the sheet member in a predetermined direction on the first housing section.

19. An apparatus as in claim 18 wherein the spring is located inside a cavity in the first housing section spaced from the hinge section.

20. An apparatus as in claim 18 wherein the sheet member extends over an exterior of the hinge section.

21. An apparatus as in claim 20 further comprising a flexible flat printed circuit cable located against an interior side of the sheet member, wherein the flexible flat printed circuit cable extends over the exterior of the hinge section.

22. An apparatus as in claim 18 wherein the sheet member is comprised of metal.

23. An apparatus as in claim 18 wherein the sheet member comprises a superelastic material.

24. An apparatus as in claim 18 wherein the sheet member has a width about a same width as the second housing section and the hinge section.

25. An apparatus as in claim 18 wherein the sheet member has a length which is greater than a longitudinal length of the first housing section and greater than a longitudinal length of the second housing section.

26. An apparatus as in claim 18 wherein the spring comprises a coil spring.

27. An apparatus as in claim 18 wherein the spring comprises at least two spaced springs connected to the second end of the sheet member.

28. An apparatus as in claim 18 wherein an exterior of the sheet member comprises plated or engraved decoration.

29. An apparatus as in claim 28 wherein the sheet member is removably connected to the first and second housing sections such that an end can replace the sheet member with a second different sheet member having a different plated or engraved decoration on the exterior of the second sheet member.

30. An apparatus as in claim 18 wherein the spring comprises an extension and contraction axis parallel to an elongate longitudinal axis of the first housing section.

31. A method comprising:

rotatably connecting a first housing section with a second housing section at a hinge section;

connecting a flexible thin foil member to the second housing section, wherein the thin foil member extends over an exterior of the hinge section and onto the first housing section; and

connecting a spring between the foil member and the first housing section to bias the foil member in tension towards a predetermined direction on the first housing section.

32. A method as in claim 31 wherein connecting the spring between the foil member and the first housing section comprises inserting an end of the foil member from an exterior side of the first housing section through a slot in the first housing section.

33. A method comprising:

rotating first and second housing sections relative to each other from a closed position towards an open position; and

pulling on a foil member by a spring as the first and second housing sections are moved towards the open position, wherein the foil member is located over an exterior side of a hinge section connecting the first and second housing sections to each other, and wherein the spring connects the foil member to the first housing section to pull the foil member in a predetermined direction on the first housing section as the first and second housing sections move towards the open position.

34. A method as in claim 33 further comprising pulling a portion of the foil member inside the first housing section as the first and second housing sections move towards the open position.
