Abstract

The present invention relates to device for synchronous opening-or-closing movement of cabinet's cupboards which mainly includes a major cupboard and two minor cupboards. The major cupboard is pivotably fitted to the center of the cabinet by means of a first hinge for turning at 180° at the original place. Both of the minor cupboards are pivotably fitted to each side of the cabinet by means of second hinges, respectively, for turning at 90° at the original place. The first hinge is provided at top of the major cupboard and is pivotably connected with two connecting rods at each side thereof. The other end of each of the connecting rods is pivotably connected to a turning point at top of the respective minor cupboards 30. When the major cupboard or the minor cupboards are turned at the original place, the other one will be brought into a synchronous opening-or-closing movement.
