Opening that accordion door with a linear actuator

Well, I didn't see a How-to for this one, so I'll put this up. I have an old-skool accordion door with a locking swing-arm as the main door to enter exit the bus. I love the glass, and the fact that it opens in, but there's no way I've found to lock it to my satisfaction, both for security and for ease. So I went with a linear actuator in place of the main bar, and a remote for controlling it.

It's on my blog here.

Please let me know if you've got questions I didn't cover there. But just so you can see the (basically) finished product:

Check out my thread. I used a linear actuator to lock the door. It pushes the shaft down into the track area just behind the door post that goes vertical into the track. This blocks the door from opening. I really like the use of an actuator to open the door as well. Nice clean work.
My wife is not having an easy time getting up and down the stairs. I keep looking at them and wondering if I could use and actuator to lift a platform up and down in stead of the steps. Almost like a small version of a wheelchair lift.
I haven't figured it out yet but your vid gives me hope.

Holybus, if your floor height is like mine (about 42-44" high), then a pair of these 48" long guys might work to extend down to the ground, then lift up to floor level. Then a sort of removable (or folding?) platform might do the trick for a side or rear exit door. Or maybe a fold-down floor over your existing stairs to meet up with the platform? It's a neat idea to play with.

At 1/4" per second travel, it takes 3.2 minutes to travel the 48". No offense, but I can imagine her response when it takes that long to get in or out.

Yes if it is not steep. She can do the steps but not too many times and only slowly. It is the height of each step that is the biggest issue. A lift in place of the steps would be ideal.
Open the door and raise and lower the platform where the steps currently are would be great. Replacing the steps with more steps and one outside that retracts may be more feasible.

Sounds like a lift-gate/observation deck on the back might be the way to go ... I'd certainly think that a railing on one of these would be the way to go up and down ...
