Patent ID: 7934292

Claim:
A hinge adapted to rotatably couple a first module to a second module, the hinge comprising: an axle; a first member coupled to the axle, said first member being adapted to couple to the first module; a second member coupled to the axle and configured to rotate relative to the first member and around the axle, said second member being adapted to couple to the second module such that the first and second modules are rotatably coupled via said axle, said first member and said second member; a stop mechanism configured to stop the second member from rotating, relative to the first member, in a first direction and beyond a first range when the stop mechanism is in a first position and the second member is in the first range, the stop mechanism further configured to allow the second member to rotate, relative to the first member, in the first direction, beyond the first range, and into a second range when the stop mechanism is in a second position and the second member is in the first range, the stop mechanism including a contact portion configured to receive a force for moving the stop mechanism to the second position, the contact portion extending downward from a top portion of the stop mechanism and being disposed below the top portion of the stop mechanism; a first spring mechanism attached to a first portion of the stop mechanism and configured to bias the stop mechanism toward the first position; and a second spring mechanism attached to a second portion of the stop mechanism and configured to bias the stop mechanism toward the first position, the second portion of the stop mechanism being disposed opposite to the first portion of the stop mechanism, the second portion of the stop mechanism being connected to the first portion of the stop mechanism through the top portion of the stop mechanism, the contact portion being disposed between the first portion of the stop mechanism and the second potion of the stop mechanism, wherein said hinge is located entirely within and hidden by said first module while said hinge is rotatably coupling the first module to the second module.
