Abstract

Claims (36)

1. An electronic device comprising:

a first portion;

a second portion;

a third portion;

a torque-optional hinge that movably connects the third portion to the second portion, the torque-optional hinge having a hinge axis and a means for selectively generating a torque around the hinge axis by a radial compression force applied to the hinge axis, wherein the means for selectively generating the torque has a high-torque state and a low-torque state, the high-torque state providing a greater rotational resistance around the hinge axis than the low-torque state; and

a support hinge positioned between the first portion and the third portion, the support hinge rotatably connecting the first portion and the third portion and providing a torque around a support axis, wherein the support hinge is connected to the first portion away from a lower edge of the first portion, allowing the lower edge to move away from the third portion.

2. The electronic device of claim 1 , wherein the means for selectively generating the torque includes a frictional torque element.

3. The electronic device of claim 1 , wherein the low-torque state provides no rotational resistance.

4. The electronic device of claim 1 , wherein the means for selectively generating the torque includes a flexible connector.

5. The electronic device of claim 4 , wherein the flexible connector includes a fabric.

6. The electronic device of claim 1 , wherein the means for selectively generating the torque includes selecting a quantity of friction clips generating torque on an axle positioned at the hinge axis.

7. The electronic device of claim 1 , wherein the means for selectively generating the torque provides different torque in a first rotational direction and a second rotational direction.

8. The electronic device of claim 7 , wherein the high-torque state and low-torque state are independent of one another in the first rotational direction and the second rotational direction.

9. The electronic device of claim 1 , wherein the support hinge has an open state and a closed state, and wherein the torque-optional hinge is in the high-torque state when the support hinge is in the closed state and the torque-optional hinge is in the low-torque state when the support hinge is in the open state.

10. The electronic device of claim 1 , wherein the torque-optional hinge includes a ratcheting mechanism that allows resists rotation in first rotational direction when engaged.

11. The electronic device of claim 1 , wherein the torque-optional hinge includes a pair of opposing ratcheting mechanisms that resist rotation around the hinge axis when engaged.

12. The electronic device of claim 1 , wherein the means for selectively generating the torque includes an axle and a clamp that applies a radial compression to the axle to generate friction with the axle.

13. The electronic device of claim 12 , wherein the one of the axle and the clamp is fixed relative to the first portion and the other of the axle and the clamp is fixed relative to the third portion, the means for selectively generating the torque generating friction when the support hinge is in a closed state.

14. The electronic device of claim 1 , wherein the support hinge has a range of motion up to 180°.

15. An electronic device comprising:

a first portion;

a second portion;

a third portion;

a torque-optional hinge that movably connects the third portion to the second portion, the torque-optional hinge having a hinge axis and a torque element with a ratcheting mechanism configured to selectively generate a torque around the hinge axis by a radial compression force applied to the hinge axis, wherein the torque-optional hinge has a high-torque state and a low-torque state, the high-torque state providing a rotational resistance around the hinge axis and the low-torque state allowing rotation around the hinge axis without additional rotational resistance; and

a support hinge positioned between the first portion and the third portion, the support hinge rotatably connecting the first portion and the third portion and providing a torque around a support axis, wherein the support hinge is connected to the first portion away from a lower edge of the first portion, allowing the lower edge to move away from the third portion.

16. The electronic device of claim 15 , wherein the ratcheting mechanism is a first ratcheting mechanism that provides torque in the high-torque state around the hinge axis in a first rotational direction, and

the torque element further comprises a second ratcheting mechanism and the second ratcheting mechanism provides torque in the high-torque state around the hinge axis in a second rotational direction.

17. The electronic device of claim 15 , wherein a pawl of the ratcheting mechanism is engaged and disengaged with a ratchet gear of the ratcheting mechanism by an electromagnetic actuator.

18. The electronic device of claim 15 , further comprising an electromagnetic actuator controlled by software of the electronic device.

19. An electronic device comprising:

a first portion including a display;

a second portion including an input device;

a third portion connecting the first portion to the second portion;

a torque-optional hinge that movably connects the third portion to the second portion, the torque-optional hinge having a hinge axis and a torque element configured to selectively generate a torque around the hinge axis by a radial compression force applied to the hinge axis, wherein the torque-optional hinge has a high-torque state and a low-torque state, the high-torque state providing a greater rotational resistance around the hinge axis than the low-torque state; and

a support hinge positioned between the first portion and the third portion, the support hinge rotatably connecting the first portion and the third portion and providing a torque around a support axis, wherein the support hinge has an open state and a closed state, and wherein the torque-optional hinge is in the high-torque state when the support hinge is in the closed state and the torque-optional hinge is in the low-torque state when the support hinge is in the open state, wherein the support hinge is connected to the first portion away from a lower edge of the first portion, allowing the lower edge to move away from the third portion.

20. The electronic device of claim 19 , wherein the display is a first touch-sensitive display and the input device is a second touch-sensitive display.
