Instructables
     I've been toying around with this idea for a while. I am living in a studio apartment and they don't like it when I do wielding in my kitchen. Something about fire codes...The idea came from my friend Sean who is in a wheelchair. I made the joke about modifying his wheelchair with a lift kit and some bottom lights but he said he'd rather have something that kept him from getting muddy and wet when it rains. His wheels pick up mud and when he uses his hands to propel himself forward his hands and arms get dirty. Since it rains about 300 days out of the year here I started brainstorming. After many bad ideas I came up with this one. The problem is I can't build it. I have a basic idea for the design and was hoping someone might build it and test it out.

Step 1: The idea

Picture of The idea
     The idea is to add a ratchet-cover like attachment that cups about 1/4th or 1/6th of the wheel on both sides. The cover would probably cover the wheels handles and so would need to have handles itself. The cover would be attached to the ratchet portion which is attached to the wheel hub. The whole thing should ratchet backwards and lock in place so it can be propelled forwards with the wheel. If someone wanted to get fancy they could add a reversible locking mechanism where the user could flip a switch/button and it could ratchet forwards and lock backwards allowing the user to move backwards as well. I thought to keep it simple just allow the ratchet to fall back out of the way and let the user have access to the wheels again.

Sorry, but this would not be very effective when it comes to transfering into a car, and then tearing down the chair in order to pass it over you, to the place that you want it until needed again. Good idea fof a transport chair, but not for my Quikie Ti.

I had a friend who does wheelchair track mention removable wheels. My goal was to make this as easy to use, lightweight, sturdy, and low profile as possible. I wanted the whole thing to be little to none wider than a regular wheel but still able to be collapsed. Is there any way you could think of to make it more "streamline" or be able to collapse in a different way to be more versatile?

The fender frame should be mounted solid. The fender it self should be on sliders. As you need the fenders you slide them to the outside position. When not in use. You slide them back inward toward the chairs seat. I am in a wheel chair. This is the thought that I came up with.

So you're meaning slide them medially (inwards) when not in use and laterally (outward) when you want to use them? interesting. I just wonder how that would work? If you could sketch how you see it I it may be helpful. I haven't had much time to donate to the idea due to moving 4,000 miles away and going to graduate school but once I have a garage/shed to work from I plan on making a model for tinkering things out.

How would you go backwards?
AthleticTrainer (author)  Colourful3 years ago
My thought was that if it could be worked where you pulled outwards and backwards to change the ratchet position then pushed inwards and forwards to change it back.

Upgrade the wheel hub using a Sturmey-Archer type gear.

A life-changing idea, awesome!
