Abstract

An opening and closing mechanism includes a fixed member; a movable member disposed on the top face of this fixed member to be movable and rotatable in predetermined directions; a spring applying a spring force in the moving and rotating directions of this movable member; and a guide for restricting movement and rotation of the movable member.

Claims (52)

1. An opening and closing mechanism comprising:

a fixed member;

a movable member disposed on a top face of the fixed member to rotate and linearly move in a predetermined direction with respect to said fixed member;

a spring for applying a spring force in a moving direction and a rotating direction of the movable member;

a guide for restricting movement and rotation of the movable member; and

wherein the spring has a limiting point at which a direction to apply the spring force to the movable member inverts, the liming point being provided on at least one of a middle part in the moving direction and a middle part in the rotating direction of the movable member.

2. The opening and closing mechanism as defined in claim 1 , wherein the spring is configured with a single member.

3. The opening and closing mechanism as defined in claim 2 , wherein the spring is a coil spring whose central portion is wound, and which has ends that constitute latching parts.

4. The opening and closing mechanism as defined in claim 1 , wherein the guide comprises a stopper ring and a pin fixed to the fixed member, and an elongated hole and a continuous hole provided in the movable member; and

wherein the elongated hole corresponds to the stopper ring, and the continuous hole corresponds to the pin.

5. The opening and closing mechanism as defined in claim 4 , wherein the continuous hole has an orthogonal L-shape, with its one side parallel to the elongated hole.

6. The opening and closing mechanism as defined in claim 5 , wherein the spring has one latching part at an intersecting point of two straight lines perpendicularly crossing a middle part of each side of the L-shaped continuous hole.

7. The opening and closing mechanism as defined in claim 4 , wherein the guide further comprises a ring rotatably attached to the pin.

8. An electronic device comprising:

a fixed housing including a fixed member;

a movable housing including a movable member, the movable housing being disposed on a top face of the fixed housing to rotate and linearly move in a predetermined direction with respect to said fixed housing;

a spring applying a spring force in a moving direction and a rotating direction of the movable member;

a guide for restricting movement and rotation of the movable member; and

wherein the spring has a limiting point at which a direction to apply the spring force to the movable member inverts, the liming point being provided on at least one of a middle part in the moving direction and a middle part in the rotating direction of the movable member.

9. The electronic device as defined in claim 8 , wherein the spring is configured with a single member.

10. The electronic device as defined in claim 9 , wherein the spring is a coil spring whose central portion is wound, and which has ends that constitute latching parts.

11. The electronic device as defined in claim 8 , wherein the guide comprises a stopper ring and a pin fixed to the fixed member, and an elongated hole and a continuous hole provided in the movable member; and

wherein the elongated hole corresponds to the stopper ring, and the continuous hole corresponds to the pin.

12. The electronic device as defined in claim 11 , wherein the continuous hole has an orthogonal L-shape, with its one side parallel to the elongated hole.

13. The electronic device as defined in claim 12 , wherein the spring has one latching part at an intersecting point of two straight lines perpendicularly crossing a middle part of each side of the L-shaped continuous hole.

14. The electronic device as defined in claim 11 , wherein the guide further comprises a ring rotatably attached to the pin.

15. An opening and closing mechanism comprising:

a fixed member;

a movable member disposed on a top face of the fixed member so as to be movable and rotatable in predetermined directions;

a spring for applying a spring force in a moving direction and a rotating direction of the movable member; and

a guide for restricting movement and rotation of the movable member;

wherein the guide comprises a stopper ring and a pin fixed to the fixed member, and an elongated hole and a continuous hole provided in the movable member; and

wherein the elongated hole corresponds to the stopper ring, and the continuous hole corresponds to the pin.

16. The opening and closing mechanism as defined in claim 15 , wherein the spring is configured with a single member.

17. The opening and closing mechanism as defined in claim 16 , wherein the spring is a coil spring whose central portion is wound, and which has ends that constitute latching parts.

18. The opening and closing mechanism as defined in claim 15 , wherein the spring has a limiting point at which a direction to apply the spring force to the movable member inverts, the liming point being provided on at least one of a middle part in the moving direction and a middle part in the rotating direction of the movable member.

19. The opening and closing mechanism as defined in claim 15 , wherein the continuous hole has an orthogonal L-shape, with its one side parallel to the elongated hole.

20. The opening and closing mechanism as defined in claim 19 , wherein the spring has one latching part at an intersecting point of two straight lines perpendicularly crossing a middle part of each side of the L-shaped continuous hole.

21. The opening and closing mechanism as defined in claim 15 , wherein the guide further comprises a ring rotatably attached to the pin.

22. An electronic device comprising:

a fixed housing including a fixed member;

a movable housing including a movable member, the movable housing being disposed on a top face of the fixed housing so as to be movable and rotatable in predetermined directions;

a spring applying a spring force in a moving direction and a rotating direction of the movable member; and

a guide for restricting movement and rotation of the movable member;

wherein the guide comprises a stopper ring and a pin fixed to the fixed member, and an elongated hole and a continuous hole provided in the movable member; and

wherein the elongated hole corresponds to the stopper ring, and the continuous hole corresponds to the pin.

23. The electronic device as defined in claim 22 , wherein the spring is configured with a single member.

24. The electronic device as defined in claim 23 , wherein the spring is a coil spring whose central portion is wound, and which has ends that constitute latching parts.

25. The electronic device as defined in claim 22 , wherein the spring has a limiting point at which a direction to apply the spring force to the movable member inverts, the liming point being provided on at least one of a middle part in the moving direction and a middle part in the rotating direction of the movable member.

26. The electronic device as defined in claim 22 , wherein the continuous hole has an orthogonal L-shape, with its one side parallel to the elongated hole.

27. The electronic device as defined in claim 26 , wherein the spring has one latching part at an intersecting point of two straight lines perpendicularly crossing a middle part of each side of the L-shaped continuous hole.
