Patent ID: 6856792

Claim:
A mechanism for rotating at least a first and a second housing element of a device with respect to one another, where the first and second housing elements have a common axis of rotation, which is substantially perpendicular to a front surface of the device, the first housing element including a path, which extends at least partly around said axis of rotation at a distance away from the axis of rotation, said mechanism comprising: a tension device having a first end coupled to the first housing element, and a second end coupled to the second housing element at a point which travels around the axis of rotation along said path of the first housing element, as the first housing element and the second housing element rotate with respect to one another; a mechanical stop, which limits rotational movement, when the first and second housing elements are at or near a rotatably opened position; and an engagement member, engaged to one of the first and second housing elements and releasably engaged with the other one of the first and second housing elements, which limits rotational movement, when the first and second housing elements are at or near a rotatably closed position.
