Abstract

An electronic device provided. The electronic device includes a first body part including a first connection member and a second body part including a second connection member. At least one of the first connection member and the second connection member includes and a portion having a first flat area and a second area. The second area having a generally curved configuration and extending from the first flat area for magnetically coupling the first body part and the second body part to each other.

Claims

1. An electronic device comprising:

a first body part including a first connection member; and

a second body part including a second connection member,

wherein at least one of the first connection member and the second connection member includes and a portion having a first flat area and a second area, the second area having a generally curved configuration and extending from the first flat area for magnetically coupling the first body part and the second body part to each other.

2. The device of claim 1, wherein the first connection member and the second connection member are coupled to each other in a non-insertion type manner.

3. The device of claim 1, wherein the first connection member and the second connection member are coupled to each other in a face-to-face contact type manner.

4. The device of claim 1, wherein the first connection member is made from magnet material and the second connection member is made from a metal.

5. The device of claim 1, wherein with the first body part and the second body part magnetically coupled to each other, the first body part and second body part are moveable relative to each other between a folded configuration and an unfolded configuration.

6. The device of claim 1, wherein a first coupling surface having a first curvature is formed in a first coupling portion of the first body part and a second coupling surface having the first curvature is formed in a second coupling portion of the second body part.

7. The device of claim 6, wherein a third coupling surface having the first curvature is formed in a third coupling portion of the first body part and a fourth coupling surface having the first curvature is formed in a fourth coupling portion of the second body part.

8. The device of claim 7, wherein the first and third coupling surfaces have substantially the same coupling surface configurations and the second and forth coupling surfaces have substantially the same coupling surface configurations.

9. The device of claim 1, wherein the first connection member comprises:

a magnet; and

a first metal body attached to at least one side of the magnet.

10. The device of claim 6, wherein the first connection member is defined by at least four connection members that are equidistantly spaced apart from each other and arranged at an upper portion and a lower portion of the first coupling surface of the first body part.

11. The device of claim 10, wherein the second connection member comprises a second metal body.

12. The device of claim 11, wherein the second connection member is defined by four connection members that are spaced apart from each other and a pair of second connection members are arranged on the second coupling surface of the second body part.

13. The device of claim 6, wherein the first connection member comprises:

a shaft disposed on the first body part along a center of the first curvature;

a magnet extending through the shaft; and

first and second metal bodies extending over the shaft and that are magnetically coupled to the magnet.

14. The device of claim 13, wherein an inner diameter of a through-hole of the first and second metal bodies is larger than an outer diameter of the shaft, so that the first and second metal bodies can be moved on the shaft.

15. The device of claim 14, wherein an outer peripheral surface of the magnet and outer peripheral surfaces of the first and second metal bodies extend along different planes.

16. The device of claim 15, wherein the outer peripheral surface of the magnet and the outer peripheral surfaces of the first and second metal bodies form a stepped configuration.

17. The device of claim 1, further comprising a holding device for maintaining the first and second body parts in a folded configuration.

18. The device of claim 17, wherein the magnet holding device comprises:

a first magnet arranged on the first body part; and

a second magnet arranged on the second housing part and having a polarity that is opposite a polarity of the first magnet,

wherein the first magnet is arranged along a coupling surface of the first body part and the second magnet is arranged along a coupling surface of the second housing part.

19. The device of claim 17, wherein the first body part and the second body part form a housing of the electronic device.
