Patent ID: 7414834

Claim:
A hinge comprising: a hinge frame, a first hinge member defining a first axis of rotation with a first element connected to the hinge frame, a second hinge member defining an offset second axis of rotation with a second element connected to the hinge frame, and synchronizing members which transfer rotational movement of the first element relative to the hinge frame to rotational movement of the second element relative to the hinge frame through a path of about 360 degrees of rotational movement of the first element in relation to the second element, wherein the hinge further comprises a locking mechanism for locking the position of the second element relative to the first element comprising a first locking member being non-rotatably connected to the first hinge member and provided with one or more indentations or protuberances positioned at predetermined angular positions in relation to the first axis of rotation, a second locking member being non-rotatably connected to the second hinge member and provided with one or more indentations or protuberances positioned at predetermined angular positions in relation to the second axis of rotation, and a third locking member being non-rotatably connected to the hinge frame and on one hand provided with one or more protuberances or indentations positioned at predetermined angular positions in relation to the first axis of rotation and on the other hand provided with one or more protuberances or indentations positioned at predetermined angular positions in relation to the second axis of rotation, wherein the third locking member is biased against the first and second locking members.
