-a form of manual lifting for the user to stand or reach objects

Something that would be helpful to me, would be to have extentions on the armrests, so they could be raised up to provide support while standing/reaching. I'm able to stand on my own, but have problems balancing, especially when reaching up for something.

I realize you're asking about manual lifting, in particular...but I wouldn't know enough about that to be confident about providing feedback. Others here are much more expert in 'all things wheely' than I am, so I hope you'll get some good feedback from them.

seat reclining

I have a slightly reclining seat on my current w/chair...I wish it reclined a bit more, but it's a nice feature as it provides pressure release when sitting for long periods of time.

Good Luck on your project!

-the use of gearing to aid the user when climbing slopes

Been done in prototype form (ive seen pictures on the web) but really adds a lot of weight for not a great advantage, I don't think it's ever made it into production - energy losses in transmission and added weight make it a bit of a non starter

-a form of manual lifting for the user to stand or reach objects

Been done - available on the market - type Levo or Lifestand into Google

-seat reclining

Plenty of them on the market already

-preventing sleeves becoming soiled when in contact with the wheels

Yes please - without too much weight or silly looking mudguards please.

-a form of manual aid for climbing stairs

If you can do this whilst keeping weight to acceptable levels you'll make an absolute mint. Trouble is most chair users won't want to cart around all the extra weight all day every day.

ive had the idea of using a gas strut that are commonly found in office chairs which adjusts the high for the user. This would then give support when you would raise urself up. these struts are also fairly light and shouldnt add any more weight to the chair.

Like I said above it's been done before - that's how my standing chair works.

Ooops sorry - the standing chair uses a gas strut like in a car rear hatchback. Some of the power chairs raise like you describe, be quite clever if you can do it on a manual without adding too much weight or losing rigidity.

hey peeps

sorry i havent posted for a long time as i have been without the internet for a while!

i been busy on my designs and i think i come up with some good ideas and i could do with a little bit of help in some ares.

if i said that i cud make u a wheelchair that can climb a small amount of steps manually (ie public steps not a flight of stairs), could also travel on rough terain, raise the user to a standing position and prevent the users sleeves becoming soiled when in use. All this and it weighs as much as a conventional manual wheelchair!.

Would you guys be interested hypothetically?

the only problem in the design at the moment is that extra effort would be required for the user to climb steps but this would not be an impossible amount.

any response would be appreciated.

thanks

rich

p.s. i will post a concept ASAP!!!!

[bubbleandsqueak]

i would be interested.

right now to climb steps i have a ramp in the back of my truck it's made for motor bikes and things of that sort to get them into the bed of the truck but works vary good for five - six steps. (all thow the more steps the steper the hill the more pushing i'll need.
