Any ideas on inexpensive door openers?

[R. Baarslag-Benson]

Our Assistive Tech Ctr is trying to help someone with a power wheelchair.
She lives in an area with frequent power outages, making electronic door
openers with battery backup very expensive.

She especially needs to be able to open an upstairs door into the
two-story garage, then a door to the outside at the bottom of a 90 ft ramp.

Has anyone heard of a mechanical setup for this?  Such as guiding her
wheelchair wheel to push down a lever sticking up out of a hole in the
floor. That could pull a cable, releasing a bolt that locks the door?

All suggestions appreciated,   Ross
