Abstract

The description relates to devices, such as computing devices that have hinged portions. One example can include a display portion that includes a display screen and an input portion that includes an input device. This example can also include a radius hinge assembly rotatably securing the first and second portions. The radius hinge assembly can be configured to provide a curvilinear articulation that allows 360 degrees of relative rotation between the first and second portions.

Claims

1. A computing device, comprising:

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

,

a hinge assembly rotatably securing the display and input portions, the hinge assembly including;

at least first and second adjacent offset stacks, individual stacks comprising a display portion element, a timed link element, and an input portion element, the timed link element having generally opposing first and second ends and a first hole formed through the first end and a second hole formed through the second end, and,

an axis pin passing through the second hole of the timed link element of the first stack and the first hole of the timed link element of the second stack that secures the second stack in an offset manner relative to the first stack, the offset manner being defined by a pitch diameter of the second end of the timed link element of the first stack and a first end of the timed link element of the second stack.

2. The computing device of claim 1, wherein the input portion comprises a housing, and wherein the input portion element is secured to the housing.

3. The computing device of claim 1, wherein the display portion comprises a housing, and wherein the display portion element is secured to the housing.

4. The computing device of claim 1, wherein the hinge assembly is configured to allow 360 degrees of rotation of the display portion and the input portion relative to one another.

5. The computing device of claim 1, wherein the hinge assembly is a progressive hinge that provides less resistance to rotation when the display portion and the input portion define a relatively small angle therebetween and progressively more resistance as the angle becomes larger.

6. The computing device of claim 1, wherein each stack includes a single timed link element or wherein each stack includes multiple serially arranged timed link elements.

7. The computing device of claim 1, wherein each stack includes a single timed link element and wherein each end of the single timed link element is geared or wherein only one of the first or the second ends is geared.

8. The computing device of claim 1, wherein relative to the first stack, the first end of the timed link element does not engage the display portion element and the second end engages the input portion element in a no-slip one-to-one rotational engagement and relative to the second stack the first end of the timed link element engages the display portion element in a no-slip one-to-one rotational engagement and the second end does not engage the input portion element.

9. The computing device of claim 8, wherein the axis pin comprises a first axis pin and further comprising a second axis pin that passes through a hole in the display portion element of the second stack and the hole in the first end of the timed link element of the first stack and a third axis pin that passes through the hole in the second end of the timed link element of the second stack and a hole in the input portion element of the first stack.

10. The computing device of claim 9, wherein the first axis pin, the second axis pin, and the third axis pin are oversized compared to the holes in the first and second stacks to create a friction fit.

11. The computing device of claim 9, wherein the first axis pin, the second axis pin and the third axis pin compress the first and second stacks against one another.

12. The computing device of claim 11, wherein the first axis pin, the second axis pin and the third axis pin comprises threaded bolts that receive threaded nuts that can be tightened to compress the first and second stacks against one another.

13. The computing device of claim 12, wherein the second axis pin and the third axis pin are on opposite sides of the first axis pin and further comprising a fourth axis pin that is adjacent to the second axis pin and distal to the first axis pin and a fifth axis pin that is adjacent to the third axis pin and distal to the first axis pin and wherein the fourth axis pin passes through a second hole in the display portion element of the second stack and a hole in the display portion element of the first stack and the fifth axis pin passes through a hole in the input portion element of the second stack and a second hole of the input portion element of the first stack and wherein the second and fourth axis pins share common link covers on each side of the first and second stacks and the first axis pin and the third axis pin share other common link covers on each side of the first and second stacks.

14. The computing device of claim 1, wherein the timed link element of an individual stack comprises first and second timed link elements and relative to the first stack, the first end of the first timed link element does not engage the display portion element and the second end engages a first end of the second timed link element in a no-slip one-to-one rotational engagement and a second end of the second timed link element engages the input portion element in a no-slip one-to-one rotational engagement and relative to the second stack the first end of the first timed link element engages the display portion element in a no-slip one-to-one rotational engagement and the second end of the first timed link element engages a first end of the second timed link in a no-slip one-to-one rotational engagement and a second end of the second timed link element does not engage the input portion element.

15. A computing device, comprising:

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

,

a radius hinge assembly rotatably securing the display and input portions and configured to provide a curvilinear articulation that allow 360 degrees of relative rotation between the display and input portions.

16. The computing device of claim 15, wherein the radius hinge assembly rotates around a set of elongate parallel axis pins and the curvilinear articulation is viewed transverse to a long axis of the axis pins.

17. The computing device of claim 15, wherein the radius hinge assembly comprises timed gearing to control curvature of the curvilinear articulation for the 360 degrees of relative rotation.

18. The computing device of claim 15, wherein the input device comprises a touch pad, a keyboard, and/or a touch sensitive display screen.

19. A computing device, comprising:

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

,

a radius hinge assembly rotatably securing the first and second portions, the radius hinge assembly including at least first and second offset adjacent stacks that collectively control rotation of the first and second portions relative to one another while preserving a minimum bend radius for the conductors between the first portion and the second portion.

20. The computing device of claim 19, wherein the hinge assembly allows the rotation from 0 degrees to 360 degrees and wherein the minimum bend radius occurs at 0 degrees and 360 degrees and a bend radius increases at intermediate degree values from the minimum bend radius.
