The Fractal Chair

Тәжірибелік нұсқаулар және стиль

I have recreated a "fractal" chair based off a patent from 1913. Similarly to the "fractal" vise that I previously restored, this chair uses the same series of pivoting sections to fully adapt to the shape of someone sitting down. The original patent can be seen here: patents.google.com/patent/US1...
I used the original patent explanation as best I could to help design the function of the chair which uses stacked tongue and groove steel plates that interface with each other through a series of ball bearings that provide the movement. The design was fully realized with the help of / joshsfick who digitally created all the pieces needed to be cut with a fibre laser.
Once the sheets of 1/4" steel were cut, I could start machining and assembling all the other components. Overall the chair weighs about 150lbs.
Sitting on the finished chair is odd. It's comfortable in how it conforms to you, but not comfortable to sit on wood slats that can sometimes be too far apart due to their movement.
There is lots of room for improvement here. Slats that are less thick would help lower the pivot point of each, so that it feels better to sit on. More "sections" would also increase the comfort. Increasing the range of each "section" and making a version where the backrest could pivot as well would be very nice.
Overall this was so much fun and I will constantly sit in it every time I get the chance.

    Those wood pieces could be taller and also wider, so that they would always be aligned upright with a help of few rubber bands going through. The holes for these bands should be long lines so that the band could move (not necessarily in the outermost panels). I also think one more layer of "fractality" and even narrower thin slices of wood would be better.

    I think the main problem is that the surface of the slats that you sit on is too offset from the axis of rotation of the last stage, and they are too narrow. This makes them want to flop over when force is placed on them, rather than pivot to be normal to the body. Also if they attached 'inside'/between the pivoting metal parts instead of 'on top' of them if would also allow them to be wide without obstructing the metal parts - may need an eccentric shaft to connect the two sides and allow the wood to still be on axis, or just use the wood as the shaft. I agree that in addition to this, some kind of flexible strap between the boards to encourage them to follow a continuous curve and be less independent would also help. Perhaps a couple of elastic straps stapled to the underside of the boards. An elastic strap may also help reset the chair to a neutral position when you get up.

    I am wondering if you can make the wooden planks to have their top surface to be almost where the center of rotation is for the smallest fractal pieces. Right now when you sit on the chair, the planks experience a big rotating torque, because the surface is far away from the center of rotation. So instead of conforming to the shape of one's bottom, they seem to want to rotate away. You might achieve this by either drilling a long hole in the planks to put the steel beam inside, or machine a groove from the bottom (which would likely be easier than drilling a long hole).

    Hello Hand Tool Rescue! 🪑 Your recreation of the "fractal" chair based on a patent from 1913 is absolutely fascinating! The concept of using pivoting sections to adapt to the shape of someone sitting down is both innovative and practical. The fact that you used the original patent as a reference to design the function of the chair is impressive, and your attention to detail shines through in the final product. The use of stacked tongue and groove steel plates and ball bearings to provide movement adds a touch of engineering brilliance to the design.

    I love the problem solving and humour. The only problem with the chair is that the slats are fractal in 2 dimensions only. To get real comfort (and extra pinching opportunities, obviously) each slat would need to be made from 4 (or more) fractal pieces. This would make the seat truly 3-dimensional (like peoples butts). The weight would only need to double or quadruple as would the complexity. :)

    Nice work. I think the main improvement would be to make it so the surface of the slats (the surface you sit on) pivots on the center axis of the last stage. If they attached 'inside' of the pivoting metal parts instead of 'on top' of them if would also allow them to be a lot wider. Currently the slats being offset from the axis and very narrow makes them want to flop over.

    I was thinking the same. also, the chair differs from the fractal vice in that the large semi circles don't need to be nested within each other, each can , using a ball race for smoothness be arranged with the largest semi circles to the smallest from outside to inside of the chair. so long as the wooden laths are longer than the width of the posterior, then the height of the metal semi circles will not be an issue.Also, i would like to see a version of this made for a bed, because i have a bad back. we can build it, we have the technology.

    My only issue with this (besides the pinching and things which can be reduced by connecting the wood straps together with leather) is that it is only fractal in 1 dimension where as the butt would need it to be fractal in 2 dimensions. I don't know if that is even possible. But it is why soft things and not wood are now mostly used for chairs.

    I was thinking a special-made cushion where the bottom of it has a ton of extra fabric between each button-point (to the max extent of each joint), and the cushion snapped down with the big metal button snaps, two to a slat. Then you could have a cushion that wouldn't get pinched, and could kinda "accordian" to the shape the chair took- I'd recommend to go heavy on the infill though, since the infill is going to get stretched and crushed a bunch, and you want it staying firm. Think on the cushion height, so that you could still feel the mechanism operating well.

    I think what will make it more comfortable is to make the slats concave. They seem to rock back a forth a lot because the pivot point is so low. If you make the slats concave you can reduce that distance and make it so the slats auto level as opposed to roll to the max one way or the other. I think that will increase the comfort and also reduce the pinch potential.
