Abstract

A triaxial hinge for supporting a flat panel display device on an external member includes a first member, a second member, a third member and a supporting member. The first member is fixed to the external member. The second member is pivotally connected to the first member for defining a first pivot. The third member is pivotally connected to the second member for defining a second pivot perpendicular to the first pivot. The supporting base is pivotally connected to the third member for defining a third pivot perpendicular to the first and second pivots. The flat panel display device is attached to the supporting base and can be pivoted on the first, the second, and the third pivots, respectively, with respect to the first member.

Claims

1. A triaxial hinge for supporting a flat panel display device on an external member comprising:

a first member for being fixed to the external member;

a second member pivotally connected to the first member and defining a first pivot;

a third member pivotally connected to the second member and defining a second pivot perpendicular to the first pivot; and

a supporting base pivotally connected to the third member and defining a third pivot perpendicular to the first and second pivots,

wherein when the flat panel display device is attached to the supporting base, the flat panel display device is pivotable on the first, the second, and the third pivots, respectively, with respect to the first member.

2. A triaxial hinge according to claim 1, wherein

the first member further comprises two first connection plates;

the second member further comprises two second connection plates, two third connection plates and two first bolts, wherein the two second connection plates are pivotly connected to the two first connection plates of the first member by the first bolts, respectively, and the two first bolts define the first pivot; and

the third member further comprises two forth connection plates and two second bolts, wherein the two forth connection plates are pivotly connected to the two third connection plates of the second member by the second bolts, respectively, and the two second bolts define the second pivot.

3. A triaxial hinge according to claim 2, wherein:

the supporting base further comprises a thread hole and a third bolt, wherein the supporting base is pivotly connected to the third member by the cooperation of the thread hole and the third bolt, and the third bolt defines the third pivot.

4. A triaxial hinge according to claim 3, further comprising a first, a second, and a third torque adjusting means for adjusting the torque turning the first member relative to the second member, the second member relative to the third member, and the third member relative to the supporting base, respectively.

5. A triaxial hinge according to claim 4, wherein the first, the second, the third torque adjusting means are washers.

6. A triaxial hinge according to claim 2, further comprising a first, a second, and a third limiting devices for restricting the rotation angle of the first member relative to the second member, the second member relative to the third member, and the third member relative to the supporting base, respectively.

7. A triaxial hinge according to claim 6, wherein:

the first limiting device comprises a first projection disposed on the first member and a first slot disposed on the second member;

the second limiting device comprises a second projection disposed on the second member and a second slot disposed on the third member; and

the third limiting device comprises a third projection disposed on the third member and a third slot disposed on the supporting base.

8. A triaxial hinge according to claim 1, wherein the external member is a holder frame.

9. A triaxial hinge according to claim 1, wherein the external member is a wall.

10. A triaxial hinge according to claim 1, wherein the external member is a bracket.

11. A triaxial hinge according to claim 1, wherein the flat panel display device is an LCD display.

12. A triaxial hinge according to claim 1, wherein the flat panel display device is a plasma display.

13. A triaxial hinge according to claim 1, wherein the flat panel display device is a light-emitting diode display.
