PURPOSE: An opening and closing control device for a flat door of furniture is provided to stably open and close a door by elastically supporting the opening and closing angle of the door. CONSTITUTION: An opening and closing control device for a flat door of furniture comprises a housing(100), a rotary shaft(200), a slider(300), a spring(400), and a link member(500). The housing supports the rotary shaft, the slider, and the spring. The housing has a hollow part(130), a guide groove(140), and a fixing part(110). The guide groove guides the sliding of the slider. The rotary shaft is rotatably installed in the hollow part of the housing and is rotated when a flat door is opened and closed. Cam protrusions(210) are formed in both sides of the rotary shaft. The slider is buried in the hollow part of the housing and is slid when the rotary shaft is rotated. The spring supplies elastic force to the slider so that the slider can be elastically slid. The link member is folded and unfolded depending on the rotation angle and speed of the rotary shaft to control the opening and closing of the door. |
