Claim:
A cellular telephone/personal digital assistant combination device having a first portion and a second portion, the first portion being pivotably adjustable in two directions relative to the second portion, the device comprising: a biaxially pivotable hinge interconnecting the first portion and the second portion; and a disengagable uniaxially pivotable hinge capable of selectively (a) interconnecting the first portion and the second portion and (b) releasing connection between the first portion and the second portion, the selectivity being dependent upon a rotational position of the first portion relative to the second portion about the uniaxially pivotable hinge, wherein the uniaxially pivotable hinge comprises: a female portion; and a male portion, wherein the male portion comprises an actuator having an engagement interface profile, which, cooperates with a complementary profile of the female portion, wherein the depth of engagement of the male portion with the female portion increases from a disengaged position to a fully engaged position with increase in rotational separation of the first portion relative to the second portion measured perpendicularly to an axial direction to the second hinge.
