A hinge device has a base adapted for secured engagement with the doorframe, a mediate plate movably connected to the base via a first adjustable cam in a first direction and a top plate movably connected to the mediate plate via a second adjustable cam in a second direction which is orthogonal to the first direction An adjustable bolt is adapted to be threadingly extended through a portion of the arm to connect to a portion of the top plate and to abut a surface of the mediate plate. Therefore, rotation of the first adjustable cam drives the base to move relative to the mediate plate in the first direction, rotation of the second adjustable cam drives the mediate plate as well as the base to move relative to the top plate in the second direction and rotation of the adjustable bolt changes a distance between the moving seat and the adjustable seat.
A hinge device comprising a moving seat adapted to be mounted on a door, an adjustable seat adapted to be mounted on a doorframe and an arm having a first end pivotally connected to the moving seat and a second end firmly connected to the adjustable seat, wherein the improvements comprise:
