Abstract

The description relates to devices, such as computing devices that have hinged portions. One example can include a first portion and a second portion. This example can also include multiple interconnected friction engines that secure the first portion and the second portion. An individual friction engine can define an axis of rotation of the first portion relative to the second portion. The example can also include sequencing elements that control a relative order of rotation of the multiple interconnected friction engines and overlapping hinge covers that protect the multiple interconnected friction engines and stabilize the timing elements.
