Abstract

The disclosure relates to a hinge assembly ( 70 ) and a tablet-notebook hybrid computer ( 10 ). The hinge assembly ( 70 ) comprises a hinge ( 40 ) for pivotably connecting a base member ( 20 ) of the tablet-notebook hybrid computer ( 10 ) to a tablet member ( 30 ) of the tablet-notebook hybrid computer ( 10 ); an actuator ( 51 ) fixed to the hinge ( 40 ); and a support member ( 50 ) pivotably connected to the tablet member ( 30 ) via a pivot shaft ( 52 ). When the tablet member ( 30 ) rotates towards an open position with respect to the base member ( 20 ), the support member ( 50 ) is actuated by the actuator ( 51 ), rotates away from the tablet member ( 30 ), and provides addition support for the tablet member ( 30 ).

First claim

The invention claimed is:

1. A hinge assembly ( 70 ) for a tablet-notebook hybrid computer ( 10 ), comprising:
a hinge ( 40 ) for pivotably connecting a base member ( 20 ) of the tablet-notebook hybrid computer ( 10 ) to a tablet member ( 30 ) of the tablet-notebook hybrid computer ( 10 );
an actuator ( 51 ) fixed to the hinge ( 40 ); and
a support member ( 50 ) pivotably connected to the tablet member ( 30 ) via a pivot shaft ( 52 ),
when the tablet member ( 30 ) rotates towards an open position with respect to the base member ( 20 ), the support member ( 50 ) is actuated by the actuator ( 51 ), rotates away from the tablet member ( 30 ), and provides additional support for the tablet member ( 30 ), wherein the support member ( 50 ) has a first end pivotably connected to the tablet member ( 30 ) and a free second end, and wherein the additional support is provided by a foot ( 53 ) of the free second end and the support member ( 50 ) is separate from the base member ( 20 ).

2. The hinge assembly ( 70 ) of claim 1 , wherein the actuator ( 51 ) is a cam.

3. The hinge assembly ( 70 ) of claim 2 , wherein the cam includes a cam lobe ( 54 ) which contacts and actuates the support member ( 50 ) when the tablet member ( 30 ) rotates with respect to the base member ( 20 ).

4. The hinge assembly ( 70 ) of claim 3 , wherein when the tablet member ( 30 ) rotates towards the open position with respect to the base member ( 20 ), the cam contacts with a midportion between the first end and the free second end, so that the free second end rotates away from the tablet member ( 30 ) and rests on a surface so as to support the tablet member ( 30 ).

5. The hinge assembly ( 70 ) of claim 4 , further comprising a spring ( 60 ) fit over the pivot shaft ( 31 ), for biasing the support member ( 50 ) back when the tablet member ( 30 ) rotates to the closed position with respect to the base member ( 20 ).

6. A tablet-notebook hybrid computer ( 10 ), comprising:
a base member ( 20 );
a tablet member ( 30 ); and
a hinge assembly ( 70 ), the hinge assembly ( 70 ) comprising:
a hinge ( 40 ) for pivotably connecting the base member ( 20 ) of the tablet-notebook hybrid computer ( 10 ) to the tablet member ( 30 ) of the tablet-notebook hybrid computer ( 10 );
an actuator ( 51 ) fixed to the hinge ( 40 ); and
a support member ( 50 ) pivotably connected to the tablet member ( 30 ) via a pivot shaft ( 52 ),
when the tablet member ( 30 ) rotates towards an open position with respect to the base member ( 20 ), the support member ( 50 ) is actuated by the actuator ( 51 ), rotates away from the tablet member ( 30 ), and provides additional support for the tablet member ( 30 ), wherein the support member ( 50 ) has a first end pivotably connected to the tablet member ( 30 ) and a free second end, and wherein the additional support is provided by a foot ( 53 ) of the free second end and the support member ( 50 ) is separate from the base member ( 20 ).

7. The tablet-notebook hybrid computer ( 10 ) of claim 6 , wherein the actuator ( 51 ) is a cam.

8. The tablet-notebook hybrid computer ( 10 ) of claim 7 wherein the cam includes a cam lobe ( 54 ) which contacts and actuates the support member ( 50 ) when the tablet member ( 30 ) rotates with respect to the base member ( 20 ).

9. The tablet-notebook hybrid computer ( 10 ) of claim 8 , wherein when the tablet member ( 30 ) rotates towards the open position with respect to the base member ( 20 ), the cam contacts with a midportion between the first end and the free second end, so that the free second end rotates away from the tablet member ( 30 ) and rests on a surface so as to support the tablet member ( 30 ).

10. The tablet-notebook hybrid computer ( 10 ) of claim 9 , wherein the hinge assembly ( 70 ) further comprises a spring ( 60 ) fit over the pivot shaft ( 31 ), for biasing the support member ( 50 ) back when the tablet member ( 30 ) rotates to the closed position with respect to the base member ( 20 ).

11. A tablet-notebook hybrid computer ( 10 ), comprising:
a base member ( 20 );
a tablet member ( 30 ); and
a hinge assembly ( 70 ), the hinge assembly ( 70 ) comprising:
a hinge ( 40 ) for pivotably connecting the base member ( 20 ) of the tablet-notebook hybrid computer ( 10 ) to the tablet member ( 30 ) of the tablet-notebook hybrid computer ( 10 );
an actuator ( 51 ) fixed to the hinge ( 40 ); and
a support member ( 50 ) pivotably connected to the tablet member ( 30 ) via a pivot shaft ( 52 ),
when the tablet member ( 30 ) rotates towards an open position with respect to the base member ( 20 ), the support member ( 50 ) is actuated by the actuator ( 51 ), rotates away from the tablet member ( 30 ), and provides additional support for the tablet member ( 30 ), wherein the support member ( 50 ) has a first end pivotably connected to the tablet member ( 30 ) and a free second end, and wherein the additional support is provided by a foot ( 53 ) of the free second end; and
wherein the actuator is a cam having a cam lobe ( 54 ) which contacts and actuates the support member ( 50 ) when the tablet member ( 30 ) rotates with respect to the base member ( 20 ).

12. The tablet-notebook hybrid computer ( 10 ) of claim 11 , wherein when the tablet member ( 30 ) rotates towards the open position with respect to the base member ( 20 ), the cam contacts with a midportion between the first end and the free second end, so that the free second end rotates away and downward from the tablet member ( 30 ) so as to support the tablet member ( 30 ).
