BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to driving technology of opening/closing a window, and more particularly to a windows opening/closing driving device.
2. Description of the Related Art
Generally, a plurality of windows are mounted on the high walls of a factory, which is not air-conditioned, for well ventilation. However, if the windows are located high and are numerous, it will be very inconvenient to open/close the windows for the user. In addition, if the factory is on fire accidentally, the windows may not be opened immediately for ventilation, and therefore the improvement is required.
To improve the aforementioned problem, an electrically controlled driver for the windows is invented. The electrically controlled driver includes a set of a motor and a screw rod. The screw rod is driven to lengthen/shorten itself by the motor to electrically control one window to be opened/closed. However, the motor and the screw rod cost a lot, and if the user intends to open/close a large number of windows, it will be necessary to install a set of the motor and the screw rod on each of the windows, such that the production cost will be relatively increased to incur universal unpopularity of the electrically controlled driver for the public.
As shown in FIGS. 12 and 13, a conventional window opening/closing driving mechanism 100 is comprised of a motor 101, a plurality of gears 103, a screw rod 102 driven by the motor 101 to drive the gears 103 to rotate, and a connecting rod 104 connected with each of the gears 103 for driving the window to be opened/closed. When there are more windows, the screw rod 102 has to be lengthened so as to increase more production cost. In addition, the screw rod 102 is subject to axial curvature while it is lengthened overmuch to cause unstable status like shaking or trembling during the rotation to further incur noise or vibration or other problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a windows opening/closing driving device, which is structurally simple for synchronically driving windows to be opened/closed and which production cost is lower than the prior art.
The secondary objective of the present invention is to provide a windows opening/closing driving device, which can control numerous windows to be opened/closed once by an easy way.
The third objective of the present invention is to provide a windows opening/closing driving device, which is almost noiseless and of no vibration.
The foregoing objectives of the present invention are attained by the windows opening/closing driving device, which is mounted on a building and connected with a plurality of windows and includes driving means fixed on the building, returning means fixed on the building, a rope passing by the windows and having two ends respectively connected with the driving means and the returning means, and a plurality of connecting members each having two connecting portions respectively connected with the rope and one of the windows.
