Force required to lift Wall Bed
Hello
I have a 62"x 82" wall bed consisting of maple and aluminum framing, fascia and mattress panels and a mattress weighing 195 lbs
The basic design for raising these beds is to have two pistons on either side of the head of the bed push down..which raises the bed into a vertical position in a case.
If 0,0 is the bottom left corner of the bed looking lengthwise, the piston connects at 1.75",6" (the other end of the piston attaches vertically to the casework that surrounds the bed). The Pivot point is at 8.25", 4".
I am not sure what other dimensions are germane that can't be derived form the above
I understand that the formula is [I][SUB][I]F[SUB]e[/SUB] = F[SUB]l[/SUB] · d[SUB]l[/SUB] / d[SUB]e

But am having trouble determining the values for di and de..... Fe = 195*(what/6.5)
And once determined, do the two pistons share the load..i.e if Fe = 1000 would I need two pistons capable of deploying 500 pounds each?
I would appreciate any insight you can provide. Thanks[I][SUB]
