Making coolest self-raising loft bed for kid - please help with hardware! Answered
Hi everybody. I am going to make a loft bed that will raise automatically when my kid gets out of it. What I'd like to do (please see attached files) is suspend the bed via pulleys and cables attached to one weight. The weight would be just a pound or two (trimmable, of course) more than the frame, mattress, bedding, etc. so it will raise itself until the weight hits a stop leaving the bed a few inches from the ceiling. If necessary some friction could be used to keep the speed reasonable. At night it should pull down quite easily, and I believe that with this layout, it should come down evenly regardless of where it is being pulled.
I had wanted this to "float", but since it is going to be in a corner anyways, I may run a couple tracks down the wall with hardware to guide the bed and keep it from swinging.
The big question I have is how to fasten this to the ceiling. It is drywall with joists above. Offhand I'm guessing the bed will be say 110 pounds, so about 225 pounds hanging from the ceiling with the bed empty. I'd like to have an extra, what, 500 pounds wiggle room? Worst case scenario, two 150 pound people sitting on the end of the bed... I mean I can explain that this is a one person only contraption, but I REALLY don't want it coming down regardless of what gets thrown at this thing.
Any ideas, criticisms, feedback, will be so greatly appreciated. I think this could be really awesome, and I know it will make my son flip out! He's got a very small room, and this will free up so much space.
Thanks again. John
