In reply to David Buckett:
If it goes to the floor why waste hinges on it, just sit it on the floor against the wall. It's the tension anchors at the top that require more care. When I've done this in the past I used expansion anchors to bolt on a 2x4, I then built off that for convenience. You could equally well bolt on some hangers to attach your chain to.
Or better use a compression member across near the ceiling. Hinge it to a spreader on the opposite wall saving drilling any significant sized holes (screws and rawl plugs will do since loads on them are small and almost entirely in shear if you do it right). Pass it through a hole near the top of your wall (or a notch in the top and the angle can be changed by moving pegs in the compression strut. It's a neat solution requiring minimal drilling and no great structural strength in the building wall material.
