Abstract

The description relates to devices, such as computing devices that have hinged portions. One example can include a first portion that includes an electronic component and is electrically connected by electrical conductors to a second portion that includes a second electronic component. This example can also include a two axis hinge assembly rotatably securing the first and second portions. The two axis hinge assembly can include a directional locking mechanism on a first axis of rotation such that when operated in one rotational direction the first axis has less resistance to rotation than a second axis. When operated in an opposite rotational direction the first axis has more resistance to rotation than the second axis.

Claims

1. A computing device, comprising:

a first portion and a second portion; and

,

a progressive hinge assembly rotatably securing the first portion and the second portion in a range of orientations from a storage orientation to a deployed orientation, the hinge assembly including;

at least first and second hinge sub-assemblies, wherein the first hinge sub-assembly provides a first range of rotation and the second hinge sub-assembly provides a second range of rotation, wherein in an instance where the first portion and the second portion are positioned parallel to one another in the storage orientation the first hinge sub-assembly offers less resistance to rotation than the second hinge sub-assembly.

2. The computing device of claim 1, wherein the first portion comprises a first housing and wherein the second portion comprises a second housing and wherein the first hinge sub-assembly is secured to the first housing and the second hinge sub-assembly, and the second hinge sub-assembly is secured to the second housing.

3. The computing device of claim 1, wherein the first hinge sub-assembly extends a contact length of the computing device upon completion of the first range of rotation compared to a contact length of the first housing.

4. The computing device of claim 1, wherein the first hinge sub-assembly functions as a foot and wherein the foot extends a contact length of the computing device upon completion of the first range of rotation compared to a contact length of the first housing.

5. The computing device of claim 1, wherein the first portion comprises an input portion that includes a keyboard and the second portion comprises a display portion that includes a display screen.

6. The computing device of claim 1, wherein the first range of rotation comprises zero to 20 degrees and the second range of rotation comprises 20 to 180 degrees.

7. The computing device of claim 1, wherein the first hinge sub-assembly includes a locking mechanism that engages when the first range of rotation is completed.

8. The computing device of claim 7, wherein the locking mechanism offers a greater resistance to rotation than the second hinge sub-assembly.

9. The computing device of claim 7, wherein first hinge sub-assembly is positioned in a housing of the first portion and the locking mechanism comprises a magnet on the first hinge sub-assembly and another magnet on a housing of the first portion.

10. The computing device of claim 7, wherein first hinge sub-assembly is positioned in a housing of the second portion and the locking mechanism comprises a magnet on the first hinge sub-assembly and a ferromagnetic material on a housing of the second portion.

11. The computing device of claim 7, wherein the locking mechanism comprises a resiliently biased object that is biased into a detent.

12. The computing device of claim 11, wherein the resiliently biased object comprises a ball bearing or wherein the resiliently biased object comprises a rod shaped object that is resiliently biased with a spring.

13. The computing device of claim 1, wherein when the first portion and the second portion are rotated apart, the first hinge sub-assembly completes the first range of rotation before the second hinge sub-assembly starts the second range of rotation, and wherein once the first and second portions are rotated past the first range, the first hinge sub-assembly offers more resistance to rotation than the second hinge sub-assembly when the first and second portions are rotated back towards one another.

14. A computing device, comprising:

a first portion that includes a first electronic component and is electrically connected by electrical conductors to a second portion that includes a second electronic component; and

,

a two axis hinge assembly rotatably securing the first and second portions, the two axis hinge assembly including a locking mechanism on a first axis of rotation such that when operated in one rotational direction the first axis has less resistance to rotation than a second axis and when operated in an opposite rotational direction the first axis has more resistance to rotation than the second axis.

15. The computing device of claim 14, wherein the first axis is associated with a locking mechanism that is configured to engage when the first axis completes a range of rotation.

16. The computing device of claim 15, wherein the locking mechanism is configured to have a resistance to rotation in the opposite rotational direction that is greater than the resistance to rotation of the second axis.

17. The computing device of claim 16, wherein after the locking mechanism is disengaged, the first axis is configured to have a resistance to rotation in the opposite rotational direction that is less than the resistance to rotation of the second axis.

18. A computing device, comprising:

a display portion that includes a display screen and an input portion that includes an input device; and

,

a progressive hinge assembly rotatably securing the display portion and the input portion and configured to allow the input portion and the display portion to be oriented generally parallel to one another in a storage orientation and rotated relative to one another into multiple orientations, and wherein starting at the storage orientation and rotating the input portion and the display portion away from one another, the progressive hinge assembly is configured to offer a relatively low resistance to rotation through a first range of rotation and then a relatively high resistance to rotation through a second range of rotation.

19. The computing device of claim 18, wherein the progressive hinge assembly comprises a first hinge sub-assembly configured to rotate through the first range of rotation and a second hinge sub-assembly configured to rotate through the second range of rotation and then when the input portion and the display portion are rotated toward one another, the second hinge sub-assembly is configured to rotate back through the second range of rotation before the first hinge sub-assembly rotates back through the first range of rotation.

20. The computing device of claim 18, wherein when a direction of rotation is reversed, the progressive hinge assembly is configured to provide the relatively high resistance to rotation through the second range of rotation, followed by a very high resistance of rotation between the second range and the first range followed by the relatively low resistance to rotation through the first range.
