Abstract
The description relates to hinged devices, such as hinged computing devices. One example can include first and second portions that rotate around a hinge shaft that is fixedly secured to the first portion and rotationally secured to the second portion. The second portion defining a first contact surface spaced apart from a second contact surface. Multiple friction clips friction fit around the hinge shaft and rotating with the hinge shaft between the first contact surface and the second contact surface.
Claims8
A device, comprising:
- first and second portions that rotate around a hinge shaft that is fixedly secured to the first portion and rotationally secured to the second portion;
- the second portion defining a first contact surface spaced apart from a second contact surface;
- and,
- multiple friction clips friction fit around the hinge shaft and rotating with the hinge shaft between the first contact surface and the second contact surface, individual friction clips having different free ranges of rotation as defined at least in part by the first contact surface and the second contact surface, the multiple friction clips having differing widths from one another as measured in a direction perpendicular to the first contact surface.

A device, comprising:
- first and second portions that rotate around a hinge shaft;
- opposing first and second contact surfaces defined by the first portion and/or the second portion;
- and,
- multiple friction clips that are friction fit around the hinge shaft, individual friction clips are free to rotate with the hinge shaft in a free range of rotation defined between the first contact surface and the second contact surface and cause resistance to further rotation when contacting either of the first and second contact surfaces, and two of the multiple friction clips have different free ranges of rotation from one another.

A device, comprising:
- first and second portions that rotate around a hinge shaft that is fixedly secured to the first portion and rotationally secured to the second portion;
- the second portion defining a first contact surface spaced apart from a second contact surface and the second contact surface comprises a sequence of stair steps;
- and,
- multiple friction clips friction fit around the hinge shaft and rotating with the hinge shaft between the first contact surface and the second contact surface, individual friction clips having different free ranges of rotation as defined at least in part by the first contact surface and the sequence of stair steps of the second contact surface.
