Abstract

ABSTRACT
The system relates to a system of vertically sliding windows which are moved into positions desired by a compressed air or liquid system. The compressed air or liquid system powers cylinders which are attached directly to the movable window sections which are inside of the frame or indirectly, thru pulleys, cables, tapes or the like which, intern, are attached to the movable window section of the vertical sliding windows. The movable window section being opened and closed by the pressurization and depressurization of the cylinders. An actuation mean controls a valve on the line leading to a series of windows, and all the valves which control the air or liquid flow to each window. If an electric actuation means is used a manual release valve is positioned between the valve on the line and the system windows. This allows for the depressurization of the system inflated thru pressurization when the windows are closed so as to push against the window and move it into a sealed position protecting occupants from wind and rain.

7. As in claim 1 wherein the the pressure cylinder means is connected with pulleys and cables, tapes or the like which in turn are connected to the movable window section of the vertical sliding windows, the movable window section being opened and closed by the pressurization and depressurization of the pressure cylinders means.

8. As in claim 1 wherein one linear cylinder is placed above the movable window sections, cables are attached to the movable end or ends of the cylinder and the cables, tapes or the like are attached to the window thru a system of pulleys.

9. As in claim 1 wherein one linear cylinder is placed below the movable window sections, cables are attached to the movable end or ends of the cylinder and the cables, tapes or the like are attached to the window thru a system of pulleys.

10. As in claim 1 wherein one linear cylinder is placed beside the frame which holds the the movable window sections, cables are attached to the movable end or ends of the cylinder and the cables, tapes or the like are attached to the window thru a system of pulleys.

11. As in claim one where a rotary mobile cylinder-motor is placed in a space which is hidden from view through the mobile or fixed window sections and is directly connected to a pulley which secures cables, tapes or the like which are attached to the window thru a system of pulleys.

12. As in claim 1 wherein cylinders are inside the vertical channel of the window frame and directly attached to the sash of the vertically movable window.

13. As in claim 1 wherein a pressure sensitive valve for each window allows for the pressurization and depressurization of the pressure cylinder means and as such the opening and lowering of the windows.

17. As in claim 16 wherein there is a manually operated valve placed on the air or liquid line just before the electrically operated lead valve, this manually operated valve can be used to depressurize the system and as such allows for the opening of windows during emergency.

18. As in claim 1 wherein a temperature and humidity sensitive device is connected to switches and valves so as to automatically open or close the windows at a specified temperature or humidity.

19. As in claim 4 wherein a seal around the window is connected to the power means and is inflated thru pressurization when the windows are closed so as to seal the windows from wind and rain.

20. As in claim 19 wherein there is a trough in the sash or frame opposite the seal so as to accept the inflated seal, the bottom of the trough may have an irregular surface so as to further prevent leakage of air.

21. As in claim 20 wherein the seal is constructed so as to assist in locking, holding the window in an upper position.

22. As in claim 13 wherein there is a mat to cover a depressurization port in the valve in the cylinder, so that the noise is muffled when air escapes.

23. As in claim 5 wherein a seal around the window is connected to the power means and is inflated thru pressurization when the windows are closed so as to seal the windows from wind and rain.

24. As in claim 23 wherein there is a trough in the sash or frame opposite the seal so as to accept the inflated seal, the bottom of the trough may have an irregular surface so as to further prevent leakage of air.
