How can I open and close a window that works on a roller from left to right?
The house we have incorporates a security panel that prevents would be thieves from breaking in. My mother is close to 70 and from the kitchen counter the door I am trying to open and close is 38" from the edge of the counter. She is 5'6 and does not have the energy to slide the door open. She usually unlocks the door and then steps outside on to the balcony and opens it from there. I want to find a way to make it electric if possible. I haven't finished the tilework so I can still run electrical lines and switches to the area. The best idea I can come up with 12v automotive power window motor that is mounted on the right side of the opening. A dog ear be mounted on the top part of the opening for support, and a dog ear be mounted on the door...just right of the LEFT dog ear support itself which will have motion. Attach (weld) a screw onto the power window motor. When engaging the window motor to open the threaded rod revolves in place and the door opens. Same happens when the door closes. My problem for when the door is ACTUALLY supposed to stop in order to be locked by the built in handle. It needs a limiting switch that is engaged to cut power when the proper distance has been traveled. I got this idea from my gate opener for my driveway, the only difference there is that it operates on a chain and has 2 limiting switches for open and close.
My father wants to go a simple route and put a pulley on each side of the window and if you want to open / close the window you pull the appropriate line. I just see that as ugly and will be breaking eventually.
