1. A hinge mechanism comprising:
a base;
a shaft having a first axis;
a first support member for supporting said shaft and allowing said shaft to rotate around said first axis;
a second support member for supporting said first support member with respect to said base and allowing said first support
member and said shaft to swivel with respect to said base around a second axis perpendicular to said first axis; and
a cam assembly for converting a swivel movement of said shaft with respect to said base to a rotational movement of said shaft,
wherein said cam assembly comprises:
at least one projection member fixed onto said shaft; and
a control member having a side wall and fixed onto said base,
wherein said at least one projection member abuts said side wall in an open position of said hinge mechanism so as to limit
rotation of said hinge mechanism around the first axis; and
said at least one projection member is operable to slide along said side wall so as to rotate around the second axis upon
the swivel movement of said shaft.
