Stand-up wheelchair, rear wheel drive, R-net?

[wheelchairer]

Does anybody know of a Stand-up wheelchair with rear wheel drive And a R-net system?

[Burgerman]

Dont think I can recall any rear drive standing chairs at all at the moment. It doesent lend itself well to that config as all the weight is then on the casters. There was some a few years back.

Invacare had the dragon vertic but it is no longer manufactured, I think the one that is still made is the vermeiren forest 3 su

I don't know what system they use but I don't think it's r-net edit I think it's linx

[Burgerman]

Because the idea of a rear drive chassis with a stander at the front is flawed. All the user mass would be on the small casters. In front of them in fact making the situation worse. I means some other way of taking all the weight must be found, like the extra wheels on this at the footplate.

It causes some inwanted consequenes. If you must have a stander best to use front drive chassis. Or at least mid drive. But however its done it is a compromise if you want a daily chair that also stands.

well, curiously, today I saw this chair used, it is an LSTC, the mass is more or less between the front wheels, it does not have the anti-tips and I think it is r-net, it is probably not manufactured anymore

I remember those lifestand chairs. They were dynamic control. Which we can program. For free...
At least the one I saw.
Maybe you can still get one?

The problem is that all the mass is over the front. (the reason why it doesent have anti tips) so very nose heavy. So once stood, even more so. The motors wont have enough torque to steer properly like this and theres little rear wheel traction as not enough weight on them.

Its an exaduration of the usual nose heavy rear drive chair that forces me to move the seating back to get good control on all of them. So this design will steer very badly and rear wheels will slip easily as you decelerate or reverse. And if one wheel slips then you lose control as these are the ones that steer you!

So be careful what you buy! Those front casters are having to take all his mass.

Actually I've had 3 of them for over 20 years now.

Because they are a stand-up wheelchair, they move the c.g. as far back as possible, So when you are driving them around sat down, they are nearly as agile as the BM.

You are not meant to be Driving round in them stood up. I don't know anybody who has attempted that in a stand-up wheelchair. You might stand-up, and derive a little way to get closer to the cupboard you want to open or something like that, but you wouldn't be driving round like that bloke is there.

Unfortunately they stop making them about 10 years ago

Got to say it doesent look very stable. Maybe only on a very flat surface as in the pic. Does its inhibits setup actually allow you to do as shown?

i have many cleints that drive their FWD or MWD chairs while standing. It is an essential part of life function.

Perfectly safe to do so.

[Burgerman]

I can imagine that indoors or in a bar say. But having used our streets I would be very worried about being a very tall motorised bar stool. You must have to pick your safe surfaces pretty carefully. It would make me pretty nervous! But so does moving around while elevated 12 inches/300mm in my normal chairs. I dont do that unless indoors.

[rover220]

yeah of course you need to be careful and aware of the surface etc, most only do it indoors around the kitchen etc.

Yes of course indoors, on a safe surface, But that guys is out in the park LOL

No they Were definitely R-net BTW. It's what I'm using now.

I am still looking LOL
