Most chairs that I have seen, utilize the “flipper” behind the back support. Some are bolted using one washer, or none, in between the folding parts. Some designs rub on the sides of the main frame support, and over time show scraping marks, and can also bind if folded after moist weather.
In designing this chair, I felt it was important to keep the integrity of my original chair design, with the tapered back support. Since I, and many fellow Canadian cottagers, prefer to paint our chairs in bright colours, it was also important that there was sufficient space between the folding parts, yet keeping the structural strength.
In experimenting with various options, including nylon futon bushings and metal porch glider mechanisms, I found an inexpensive and strong solution to the needs of this design. While you can still build this chair using regular carriage bolts with washers between the folding parts, over time the holes may get larger and the chair may get sloppy.
I used carriage bolts encased in polyethylene tubing and custom made 1/4” washers, using UHMW plastic, used for table saw and router jigs for smooth movement. The image above, showing the chair in the upright position, is identical to the original in position and comfort. The next image shows the chair reclined to 50 degrees….a very comfortable snoozing position. The back is supported by the arms and curved back seat slat, and all pieces are screwed and glued with Gorrilla Glue for the necessary strength. A recent Customer picked up some plans at my home and sat in one of the final prototypes. He found it very comfortable in the reclined position, and strong enough to hold his over 6’ height and 210 lb. weight.
The chair folds to 12 1/2” (3.81cm) and can hang on the wall of my garage.To fold the chair, push on the back and walk it forward into the folded position. To open the chair, pull up on the back. The chair will open to the reclined position, then pull on the back support to put it in the regular 65 degree angle. To recline the chair, while sitting in it, reach back and pull the back support forward.
If you are using your chairs on uneven ground or on the beach, I added stop locks to the back supports. This will eliminate the back from reclining into the sand. To fold the chair, push the back support forward to unlock it, and fold forward.
