We have a room with a high ceiling and a set of four windows.
The windows start at about 7 feet.
The person who lives in the room is not tall and currently has to use a ladder to open and close them.
They are essential for that room's ventilation so she needs to be able to open them completely. It does, however, not matter which way they open (to one of the sides, or up, or down).
What affordable approaches exist to open a window in this height, from down below?
We realize we will probably have to replace the windows in any case.
To make it even more challenging, underneath the windows is a bed so there are limits to moving sideways to open and close the window.
It would be acceptable to have only one or two windows open-able.
They have to be reasonably secure against intrusion (i.e., they need to snap shut somehow.)
What we've considered:
a lever system that leads up to the window, like so I think. Not suitable because these systems typically only tilt the window and we need it fully open (80-90°).
sliding windows - an option, but how would we slide them from below, and how can we prevent opening from outside?
an approach using a motor - an option, but we can't think of a concrete implementation.
a rope winch-like approach, with a winch opening and closing the window - interesting, but how could the window snap shut, and be opened again, from below?
Ideas would be most welcome.
