Folding Bunk Beds
Two sets of folding bunk beds. Time well spent on a great father/son project. The first wall support was plumbed and lag screwed to horizontal framing already in the wall. Once the bed frames are temporarily bolted to the wall support frames, the second wall support was lag screwed to the wall. Angle iron feet were welded to the outer wall support uprights so that concrete wedge anchors could secure the outside legs to the ground. Toggle clamps keep the bed frames from opening or closing unless released. We cut aluminum tread plate to fit inside the 2x2 angle iron of the bed frames and then ¾ oak plywood was placed on top for a solid base. 1” screws through the bed frame then hold the tread plate and plywood in place. Mattresses are held in place with buckled straps 6” from each end of each mattress.
All framing was welded from 2x2-3/16. The bed frames were made to match standard twin size mattresses. Pivot points are at 1/3 the width of the head/foot. 5/8" bolts in sleeves with lock nuts are used for pivots. There's a 7/8" washer between bed frames and support frames for clearance. The nylon lock nuts allow for precise tension for opening and closing. Stop tabs keep the beds either exactly horizontal or exactly vertical (a nut welded to the wall support stop tabs allow for precise adjustment for horizontal).
