Double hinge axial cams
First Claim
1. A portable device, comprising:
- a first housing integrated with a display device;
a second housing movably coupled to the first housing, which is operable to open and close relative to the second housing, the first and second housings configurable from a closed position at approximately zero degrees (0°
) to an open position at approximately one-hundred and eighty degrees (180°
);
a double hinge operable to movably couple the first housing and the second housing, the double hinge comprising axial cams configured to apply a holding torque in the open position that resists the first and second housings closing;
the axial cams of the double hinge comprising cam-and-follower mechanisms, one of which opens a first half of the double hinge with less applied torque before a second half of the double hinge opens, and closes the first half of the double hinge before the second half of the double hinge closes; and
a cam face of a first cam follower comprising a different shape than a second cam follower, the cam face operable on an axial cam to apply the less applied torque.

Abstract
In embodiments of double hinge axial cams, a portable device includes a first housing integrated with a display device, and a second housing movably coupled to the first housing. The first housing is operable to open and close relative to the second housing, and the first and second housings can be rotated from a closed position at approximately zero degrees (0°) to an open position at approximately one-hundred and eighty degrees (180°), as well as rotated through approximately three-hundred and sixty degrees (360°). Double hinges are operable to movably couple the first housing and the second housing. The double hinges include axial cams that apply a holding torque in the open position that resists the first and second housings closing.
