Hinge mechanism
A fixation seat having a first guiding element and a second guiding element mounted inside of a hinge mechanism is mounted at a wall or a frame's surface. A first guided assembly and a second guided assembly are mounted at the fixation seat and respectively guided by the first guiding element and the second guiding element to move away from each other or move back. A movable assembly comprises a movable and pivotable shaft mounted through the fixation seat and optionally connected to the first guided assembly or the second guided assembly. A door is mounted at the movable assembly and pivots relative to the surface through the shaft. The movable assembly lifts and lowers the door via the shaft, connected one of the guided assemblies, guided by the guiding elements, so the hinge mechanism is adaptable to install the door at left-side or right-side surfaces.
