Patent attributes
Accessory units for electronic devices are described. The accessory units can include a panel that has a flexible substrate with a network of structural elements that are arranged to fold the panel into different forms and shapes similar to origami. For example, the panel can be bent along one or more fold lines that are defined by adjacent structural elements. In some cases, the panels are configured to fold at preferred fold lines, sometimes in non-parallel orientations with respect to each other. In one case, the accessory can be unfolded into a flat configuration and serve as a cover for the electronic device. In some cases, the accessory units can be brought behind and support an electronic device at different angles with respect to a support surface. The accessory units can also include features such as keyboards, touch pads, or other input devices for the electronic devices.
