Transformer hinge design

摘要

A mobile terminal having three parts rotatably interconnected by hinges. The terminal can be a mobile telephone having an operative position where a microphone and a loudspeaker are positioned for conversation. When not in operation, the terminal may be positioned around a user's wrist in a safe manner. Removing the terminal from the wrist requires operation of a release means or the overcoming of a predetermined force, which is a safety measure of the hinges and the terminal. The hinges provide a combination of snap or automatic rotation and freely selective rotational positions of the parts of the terminal.
