Claim:
A hinge mechanism comprising at least one hinge assembly, each one of the at least one hinge assembly having a hinge having a shaft; and a lifting seat being connected to the shaft of a corresponding hinge assembly and having a recess having a first end located at a distance to the shaft; and a second end being opposite to the first end and the shaft; a rail assembly having at least one rail seat, each one of the at least one rail seat having a channel aligning with a diameter of the shaft of the hinge of a corresponding hinge assembly and having a distal end located at a distance from the shaft of the hinge; and a proximal end opposite to the distal end and located between the corresponding hinge assembly and the distal end; and a sliding bracket movably mounted between the at least one hinge assembly and the rail assembly and having a front side; a rear side opposite to the front side and located between the front side and the at least one hinge assembly; at least one upper sliding shaft protruding from the rear side, each one of the at least one upper sliding shaft mounted in the recess of the lifting seat of a corresponding hinge assembly; and at least one lower sliding shaft protruding from the front side and each one of the at least one lower sliding shaft mounted in the channel of a corresponding rail seat of the rail assembly and located at a distance to the upper sliding shaft; wherein the sum of the distance between the upper sliding shaft and the lower sliding shaft and the distance between the first end of the recess of the lifting seat and the shaft of the hinge is not greater than the distance between the distal end of the channel of the rail seat and the shaft of the hinge of the hinge assembly.
