Description

Technical area

The present invention relates to an automatically opening and closing window and, more specifically, to an automatic opening and closing device for automatically opening and closing a window unit using a drive roller rotating by means of the rotating force transmitted from a motor and a window including the same.

General state of the art

In general, a window serves as a wall member for separating an interior space from the outside and at the same time lets the sunlight and fresh air from the outside into the interior space to allow interior ventilation.

The windows are classified into different types according to their materials or their opening methods. According to the opening methods, the windows are typically divided into a turn-and-tilt type window capable of being fully opened or closed inward, a lift-and-slide window that is able to lift up from a lower rail and turn using window hardware using a lift function at the time of opening or closing and the like.

Among them, the lift and slide window includes a fixed window unit and movable window units on either one or both sides of the fixed window to be opened or closed.

Such a lift and slide window is disclosed in Korean Patent Laid-Open No. 10-2006-0025389 has been revealed.

More specifically, the lift and slide window includes a basic structure in which a fixed window unit is provided to the window frame, and a movable window unit moves in the right and left directions along rails provided on the upper and lower portions of the window frame to open or to be closed, wherein the basic structure is further provided with a window fitting such that the window fitting ensures the locking and airtightness of the window units by moving the movable window unit in the vertical or horizontal direction.

According to the lift-slide window in the above structure, when a handle is rotated to open the window, the movable window unit is lifted up from the lower rail by a predetermined height by the operation of the window fitting including a lift and, in In this state, the movable window unit moves horizontally, which is thereby opened in a noiseless and smooth manner.

Further, in the closed state of the movable window unit, the sash of the movable window unit comes into close contact with the lower rail and, accordingly, can ensure the airtightness, water tightness, insulation performance and the like.

The window is used in a relatively large-sized window for a living room, patio and the like. However, the window has a disadvantage that opening and closing the window requires a great deal of force because the window, despite its large size, should be operated manually. To solve this problem, Korean Patent Registration No. 10-0915952 discloses an automatic opening and closing device for sliding the window along a screw shaft which rotates by means of a drive means to automatically open and close the window.
