Claims
- 1. A foldable portable electric device having an upper unit, a lower unit and a hinge structure allowing said upper unit and said lower unit to fold and unfold around an axis of said hinge structure, comprising:
scraping prevention mechanism having an extension on one of said upper or lower unit and a undercut on the other unit, said scraping prevention mechanism preventing turning of said units relatively each other when said foldable portable device is in the folded position.
- 2. The foldable portable electric device as claimed in claim 1, wherein said extension is formed on an edge of either said upper or lower unit, and said undercut is formed on an edge of the other of said upper or lower unit not provided with said extension.
- 3. The foldable portable electric devise as claimed in claim 2, wherein said edge is the opposite end of said upper or lower unit connected with said hinge structure.
- 4. The foldable portable electric devise as claimed in claim 2, wherein said edge is a side end of said upper or lower unit.
- 5. The foldable portable electric device as claimed in claim 3, wherein said foldable portable electric device has at least two pairs of extensions and undercuts further comprising:
a first curved slope with a curved surface formed between said extensions; and a second curved slope with a curved surface having substantially the same curvature radius as said first curved slope, formed between said undercuts.
- 6. The foldable portable electric device as claimed in claim 1, wherein said extension is a separate part joined to either said upper or lower unit.
- 7. The foldable portable electric device as claimed in claim 1, further comprising: an elastic part for ensuring a clearance between said upper and lower units.
- 8. The foldable portable electric device as claimed in claim 1, wherein said foldable portable electric device is a cellular phone.
- 9. The foldable portable electric device as claimed in claim 6, wherein said foldable portable electric device is a cellular phone.
- 10. The foldable portable electric device as claimed in claim 9, wherein said extension is configured to light when a call is received.
- 11. A foldable portable electric device having an upper unit and a lower unit, comprising:
allowing means for allowing said upper unit and said lower unit to turn around a first axis of said connecting means; and rising means for requiring said upper and lower units to rise above each other about a second axis perpendicular to said first axis to prevent scraping damages of surfaces of said upper and lower units when said upper unit and said lower unit turn around said first axis of said connecting means.
- 12. The foldable portable electric device as claimed in claim 11, further comprising mating means, for mating with said rising means when said foldable portable electric device is in a folded position.
- 13. The foldable portable electric device as claimed in claim 11, said foldable portable electric device further comprising: curved slope means, formed at least at said upper or lower unit, for requiring said upper and lower units to rise above each other before said units can turn around said first axis.
- 14. The foldable portable electric device as claimed in claim 11, said foldable portable electric device further-comprising: elastic means for ensuring clearance between said upper and lower units.
- 15. The foldable portable electric device as claimed in claim 11, wherein said foldable portable electric device is a cellular phone.
- 16. The foldable portable electric device as claimed in claim 15, wherein said rising means is configured to light when a call is received.
