View Full Version : Projection handrims

I have to wonder if any of you use projection handrims and if you do have you ever had any adventures with them.
The pair on my chair now is the first set with an oblique angle I have ever had. The other 3 chairs I have had with projection handrims were all at 90 vertical.
I ask because yesterday when the transport van came to take me to an appointment it was an older van with a narrow lift and my chair was too wide to fit on the lift by the distance of one projection. Never had that problem in any other chair of the same width.
Come to think of it I did have problems with one chair on some of the old busses that used clamps that grabbed around the tires before they started using straps because of my handrims before.

Are you talking about quad knobs?

Yes, I couldn't handle coming down ramps with just rubber coated rims.

I have had three other chairs with vertical projections on the handrims. They didn't stick out the way these do.

We don't use those for all the reasons listed above. Have you tried wrapping rubber tubing in a spiral fashion around a regular push rim? This seems to work as well, without the problems with making the chair wider or catching thumbs or clothing that occur with quad pegs.

I cannot control my descent going down ramps with just rubber coated handrims. They also give me the extra power I need in my push when I go up ramps.
Just found out the other day that around here they call them knuckle busters.

I am a C-6 level SCI and installed a pair of "Sparkle Foam" handrims on my manual wheelchair. Unlike the vinyl they stay 'grippy' even when wet or in the cold and dry weather. They are only slightly larger in diameter (or thickness that is) than the vinyl and are tougher than the standard black soft foam handrims, so resist damage and cuts. With a pair of good gloves when you are out to protect your hands and wrists, they can be better than projections. Plus, projections caused me to get caught and trun off in the wrong direction off of things in the past, so I abandoned them.
Just my 2-cents.

Afraid I could not get a better picture right now...this chair is an old ratty one and the latex tubing is well past needing to be replaced, but wrapped a little tighter and with fresh tubing, this is much more effective than coated rims, and does not have the disadvantages of quad pegs:

It still did not give me the extra leverage I need for ramps.
