FOLDING ACCESSORY CABLE FOR PORTABLE ELECTRONIC DEVICES

摘要

Embodiments of the invention provide a folding cable. One embodiment includes stiff sections of the cable linked by flexible joints. The joints exert a small folding force on the cable so that when not pulled extended the cable tends to fold together in an accordion style to a length that approximates the portable device, such as a mobile phone, with which the cable is used. Various other embodiments are disclosed.

主权项

1. An apparatus for folding a cable of an accessory for a mobile phone, the apparatus comprising:
a first stiff section along a first portion of the cable; a second stiff section along a second portion of the cable; a first joint flexibly coupled between the first and second stiff sections; a third stiff section along a third portion of the cable; a second joint flexibly coupled between the second and third stiff sections; a first force mechanism for applying a first force so that the first and second stiff sections are moved toward each other; and a second force mechanism for applying a second force so that the second and third stiff sections are moved toward each other.
