Claim:
A hinge, comprising: an axle; a first member coupled to the axle; a second member coupled to the axle and configured to rotate relative to the first member and around the axle; a stop mechanism configured to stop the second member from rotating relative to the first member in a first direction 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; and a first spring mechanism configured to apply a torque on the second member in a second direction, wherein the stop mechanism is further configured to stop the second member from rotating relative to the first member in a second direction beyond the second range when the stop mechanism is in the first position and the second member is in the second range, and the stop mechanism is further configured to allow the second member to rotate relative to the first member in the second direction beyond the second range and into the first range when the stop mechanism is in the second position and the second member is in the second range.
