Safest wheelchair ever built

notHarry

ThIs is my new castor-wobble-free camber-eating wheelchair I'm building. It is based upon this prototype:

All I need now is to add a seat and brakes.

It uses <50% energy than any wheelchair on the market and doubles a wheelchair user's life-span in a manual chair by substantially reducing bending and twisting.

Hello @notHarry and welcome to the Community.

Your design certainly looks interesting. You'll have to let us know how the road test goes.

Best wishes

Hi @notHarry your wheelchair looks amazing what about the weight? Is it very heavy ? I’m a wheelchair user, can’t go in the car by myself as I can’t lift my chair in and out the boot.

Don't think much to the seating yet! And with that rigid piece between 2 wheels, I take it that it does not fold?

It's aluminium, so is light. Once testing is completed this year, it should be possible to create a new version that will be even lighter.

The engineers have promised a seat + brakes by the end of the month. And I hope to test them 6-7 March. The rigid piece is telescopic, so it will extend for faster downhill journeys. Upon full expansion, it will pop into two pieces. With a further modification, the rear axle will be quick-release from this rigid telescope.

I meant the block of wood between the 2 wheels. That does not seem telescopic. I think most ppl want one that goes in a car, Hence light and foldable.

notHarry

The wood is not telescopic. This is just what I had to sit on as a temporary measure to test the wheelchair steered.

The telescopic part is the square section joining the two axes. So when going down hill it can be made 30cm longer, and therefore more stable at speed

Wow @notHarry

You will be off! We won't see you for dust it looks amazing I can see it already 😊

Wheelchair manufacturers specify wheelchairs can't go above 7kph, walking speed.

Why are non-wheelchair users allowed to go faster, but those restricted in wheelchairs effectively castrated to below 7kph?

It is not fair

It is D.I.S.C.R.I.M.I.A.T.I.O.N.

Perhaps the actual wheelchair can do more damage if there is a collision? I don't know.... or could you run over small children being less able to just 'stop'?

Interesting though though.....🤔

notHarry

Better make wheelchairs static, Just to allay the concerns of the two-legs. It's their planet after all. Wheelchair people are just a nuisance and inconvenience 👆

Prototype wheelchair update 12 February.

The current welder's been on the job for nearly two years and is promising a final result within a month. ...
