Korean Utility Model Publication No. 20-0288313 discloses a motor, a gear transmission for transmitting the driving force of the motor, a drive shaft connected to the final stage of the gear transmission and across the window, and a link between the drive shaft and the window. It consists of a combined opening and closing rod.

With this configuration, the driving force of the motor is transmitted to the drive shaft through a gear transmission consisting of a screw gear, a rack gear, a drive gear, and the like, and as the drive shaft rotates, the opening / closing rod performs a link movement to open and close the windows.

However, the registration utility model publication No. 20-0288313 controls the opening and closing of windows using only electric energy, the waste of the power is severe, the overall configuration is very complicated, the economic efficiency is very low, and also the installation space due to the complex configuration In addition, the installation work is very cumbersome, and the replacement and repair is very cumbersome in case of failure.

Utility Model Registration No. 20-0246982 is a device for opening and closing the windows by the forward and backward operation of the pneumatic cylinder, a pneumatic cylinder for forward and backward operation; A piston rod fixing bracket fixed to the side of the window and fixed to the free end of the piston rod of the pneumatic cylinder; A shaft fixing bracket fixed to the window frame and having a shaft hole; A shaft inserted into the shaft hole of the shaft fixing bracket; A shaft hole into which a shaft is inserted is formed, and is fixed to the shaft fixing bracket so as to be rotatably formed, and a cylinder trunnion to which a front end portion (an end provided with a piston rod) of the pneumatic cylinder is fixed to a boss formed on one side thereof.

With this arrangement, when the piston rod of the pneumatic cylinder is moved forward and backward, the cylinder trunnion supporting the front end of the pneumatic cylinder is finely turned, and the free end of the piston rod is also finely turned, so that the window Opening and closing is done.

However, the registered utility model publication No. 20-0246982 has a structure in which the rear end portion of the pneumatic cylinder is extended to the room direction and is exposed as the front end portion of the pneumatic cylinder is fixed to the cylinder trunnion, so that the pneumatic cylinder is gravity There is a disadvantage that can be affected by the problem of malfunction.
