DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a sliding door type automatic door opening / closing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an opening and closing apparatus for opening and closing a window or door for a sliding window window, and more particularly to an opening and closing apparatus for opening and closing a window or door for a sliding window, comprising a fixing member 100, a power transmitting member 200 and a driving member 300, 100 is fixed to a window (or door) to be fixed without moving, and then the drive arm closely attached to the outer peripheral surface of the adjacent window (or door) is rotated through the motor to open and close the window (or door).

2. Description of the Related Art [0002] In general, a sliding-type window means that two or more windows (or doors) are arranged in a horizontal direction inside a frame and are opened and closed while sliding along the frame in a lateral direction. And a window-shaped window in which two windows are arranged in a horizontal direction inside the frame, which is an example for illustrating the present invention, and is not limited to the scope of the present invention.

The fixing member 100 includes a fixed body 110 having a predetermined length formed in a shape of a letter "A" so as to be coupled to the window frame 10, And a pair of first brackets (120) formed.

The fixing member 100 is formed to have a thickness, an intensity, and a predetermined length so that a sagging phenomenon is not generated or removed due to a load of the entire product when the fixing member 100 is coupled to an edge of the window frame. When the fixing member 100 is installed, for example, as shown in FIG. 1, two windows are arranged in the horizontal direction inside the frame, and a window installed on the right side is opened and closed. To the right corner of the window frame by a fastener such as a bolt. That is, the fixing member 100 is installed in a non-moving window, and the power transmitting member 200 and the driving member 300 are positioned on a window installed on the right side.

The power transmitting member 200 includes a power transmitting portion base 210 hinged to the first side bracket, a cylindrical protective cover 220 coupled to the power transmitting portion base and having an interior hollow portion, And a motor 230 mounted on the motor.

The driving member 300 includes a driving unit base 310 hinged to the first side first bracket, a bearing 320 coupled to an inner circumferential surface of the driving unit base, and one end coupled to the driving unit base, A driving roller body 330 rotatably coupled to the driving roller body via an elongated hole 331 and having an elongated hole 331 formed in a radial direction along an outer circumferential surface thereof and having a second end coupled to a rotation shaft 231 of the motor, A plurality of driving arms 340 arranged in a radial direction so as to penetrate through the elongated holes and protrude to the outside and having an upper end formed in a shape corresponding to the elongated hole and having an inclined surface 341 formed at a lower end thereof, A slope surface 351 is formed on the lower surface of the driving arm so as to correspond to the inclined surface 341 of the driving arm, A solenoid shaft 350 for projecting the driving arm outward while moving, and a solenoid body 360 for pulling the solenoid shaft to move the solenoid shaft.

The driving arm 340 is positioned inside the driving roller body 330 and protrudes outward through the elongated hole 331 when the solenoid body 350 moves toward the solenoid shaft 360.

The solenoid body 360 pulls the solenoid shaft 350. When the solenoid shaft 350 is moved, the inclined surface 351 of the solenoid shaft is inclined to the inclined surface of the driving arm 341 so that the driving arm 340 is raised and protruded outward.

Since the driving roller body 330 is coupled to the rotation shaft of the motor so as to rotate through the rotational force of the motor 230, when the motor 230 is operated, the driving roller body 330 rotates, The driving arm 340 gradually protrudes outwardly through the window 331 and is in close contact with the window to open and close the window through the rotational force of the motor.

The reason why the elongated hole 331 and the driving arm 340 are provided in the radial direction in the present invention is that when the driving roller body 330 rotates and opens and closes the window through the driving arm, So that the pulling or pushing force is continuously supplied without interruption.

Meanwhile, in the present invention, the driving arm 340 is provided with a friction pad 370 (hereinafter referred to as " friction pad ") formed of rubber, leather, artificial leather, ) Can be combined. The driving arm 340 itself may be formed of a material having excellent frictional force. However, since the entire driving arm needs to be replaced when using for a long time, it is preferable to attach a friction pad to the outer circumferential surface of the driving arm.

Also, in the present invention, the motor 230 may be electrically connected to a wired or wireless controller so that an elderly person, a patient, or a child who is uncomfortable to move easily can open and close a window. Here, the wired or wireless controller (not shown) may be a device for driving the motor 230 in a place where a window is simply installed, such as a remote control, in a narrow range, and may be a device for driving the motor 230 in a wide range. (For example, a smart phone or a notebook computer capable of wireless Internet) by controlling the motor 230 from the outside based on the IOT. When control of the motor 230 is performed based on the Internet of objects, forcible manual switching or automatic locking can be performed, thereby preventing crime due to external intrusion.

In addition, the motor 320 may be electrically connected to a window frame 10 or a sensor (not shown) provided on the outside of the window frame 10 so that the motor 320 may be opened and closed according to the operation of the sensor. For example, when a control unit for attaching an outside temperature sensor (not shown) to the window frame 10 and transmitting / receiving the outside temperature sensor is provided, if the control unit and the motor 230 are electrically connected to each other, The motor 230 may be operated according to the preset temperature so that the window 20 is automatically opened and closed. As described above, according to the present invention, various kinds of sensors can be combined to provide effects of temperature control, ventilation, and crime prevention in a room. When a fire occurs in a state where a window or a door is open, It is possible to prevent the inflow into the room, thereby reducing the damage.

Next, the present invention is characterized in that a fixing bar (130) having both side ends hinged to the driving body and the power transmitting body is provided, and a pair of second brackets And a turnbuckle 141 having a wire connecting the fixing bar 130 and the second bracket 140 is provided. The distance between the driving arm 240 and the window 20 can be easily and quickly adjusted by controlling the tension of the wire through the locking and unlocking of the turnbuckle 141 through the normal and reverse rotations.

When the motor 230 is driven after the fixing member 100 is fixedly coupled to the window frame or the door, the solenoid shaft 350 is moved toward the solenoid body 360 and the driving arm 340 is moved upward And the driving arm is rotated by the rotation force of the motor to open and close the window or the door so that it can be easily attached to or detached from the window or the door and the window Or door can be opened and closed, and manufacturing cost is low, which is advantageous in economical efficiency. Also, a wired or wireless controller can easily open or close a window or a door for an elderly person or a patient who is inconvenienced by a movement or a child.
