Abstract

Disclosed is a power supply system of an automatic ventilation device for a sliding window or door, which can easily supply power to an automatic ventilation device for a sliding window or door and prevent problems such as twisting, a breakage, or a short circuit of an external power cable for supplying power to the automatic ventilation device.

Abstract

According to the present invention, an opening and closing device of a sliding-type window or door assembly having a frame and a window or a door sliding between an opening position and a closing position, at which an opening area of the frame is opened and closed, comprises: a bracket disposed so as to be attachable and detachable from any one of the frame and the window or door; a roller unit disposed at the bracket, and rotating while coming in contact with the window or the door so as to slide the window or the door between the opening position and the closing position; and a stopper unit disposed at the bracket at a predetermined gap from the roller unit, and selectively coming in contact with the window or the door so as to stop a sliding movement of the window or the door. Therefore, attachment and detachment to/from any one of the frame and the window or the door are enabled, the window or the door can reciprocate between the opening position and the closing position by operation of the roller unit coming in contact with the window or the door, and the stopper unit can restrict the movement of the window or the door by coming in contact with the same when the window or the door stops, such that operating convenience of automatically opening and closing the window or the door can be improved and the movement of the window or the door at a predetermined position is restricted so as to enable crime prevention to improve.
