Lifestand LSC.
Plenty of pictures>>> http://s627.photobucket.com/albums/tt35 ... and%20LSC/

This is a stand up wheelchair. When stood up this achieves a very straight leg instead of the Z shape many stand up wheelchairs produce. Standing up is a very smooth action, and the independent reclining of the backrest keeps you balanced better, when you are involved in various activities such as taking pictures, if you are a high lesion like myself. The arm rests uniquely lift up and swivel, creating not so much as a chest restraint, but a barrier you can lean on to stop you falling forward, but most of the time you don’t need it. While you are stood up you are able to drive around in the wheelchair, but only on a flat surface. There are also two solid knee restraints, to keep your legs straight when standing.
The wheelchair drives lovely, with a good top speed 8k/h. The various speed settings makes it infinitely manoeuvrable. The knee height is good, and the positioning of the wheels mean if it’s a lot easier than most chairs I have used for getting in and out of places, especially under tables and such in restaurants.
The joystick has a blue button, pressing the button five times achieves five different speeds. Pressing the red button, and then using the joystick, enables you to 1. Stand a wheelchair up and sit down. 2. Move the back rest. There are two indicator switches, which if you hold the left hand down turns the lights on the front.
The wheelchair charger plugs into the front of the joystick. It takes about 2 ½/3 hours for a full charge. The LSC can run up to 8 km / h and can drive 15kms with autonomy is 2 hours about. gel dry cell batteries 4 batteries FIAMM cyclic FGC21803. I went away on holiday, and was using the wheelchair quite a lot, and the new batteries were dead within three months. This is the poorest aspect of the wheelchair, even with very low usage; they’re only last about 14 months.
The dimensions are, the width of the wheelchair at the back from the outside of the tires (the widest point) is 69 cm. The length of my wheelchair from my anti-tippers touching the door to my toes is 112 cm. Seat base 46 cm long, and 43 cm wide. The weight 90 kg. tyre 200 x 50 front tyres
rear tyres maker's name Vanonni 4PR tube tyre 300-8 maximum load 350 1a-2804-4

I really liked the wheelchair. I like the look of it, I did have the pushing handles cut off, mostly from aesthetic reasons.

Nice pictures... If you feel like adding to the collection, I'd be interested in more shots of the linkages and other workings under the seat. Especially how they do the seat elevation, and keeping the back in the appropriate relation to the seat.

A very interesting chair!
Seems very light at 90 kg. Width and length are more than we like, but interesting capability. Looks like the choice of batteries and charger should be investigated! I also would be interested in seeing more.

Best,

Martin

The reason its light is because the batteries are only half the capacity needed for the job. In the case of chairs that do tricks like this that is usually the case.

You have to really need the trick to compromise the chair so badly.

Hmm... Might be a really good place to look at a LiFe pack then - doing the approach of going for Ah on the order of a pair of big Pb's in a smaller package...

I know that I think that "trick" of enabling one to stand is one that I'd give a great deal to be able to do....

Quite! I wish someone would explain some of this stuff to the idiots making the chairs :(

Hi, I have had one of these for about eight years. Never been able to use it because it tyips over backwards attempting to negotiate inclines. I love this chair except for this. Can anyone suggest remedy. Three WC mechanics have said no adjustment available.

One of the things I haven't quite understood the reason for, but seems to be common to all the standing chairs and standing frames that I've seen is that they don't stand up all the way, only to about 80-85*... Seems like if you want to stand up so that you can do something like use a power tool or do work on a counter or bench that this would not be enough. Why can't they give you 90* like an AB? To the extent that it could be done without having to worry about doing a face-plant, I'd actually like to even be able to lean forwards (probably I'd need some sort of extend / retract control on the chest restraint since my trunk control is iffy, but I'd think it would be possible...)

One of the things I like about the chair in the OP is that it appears to get closer to true vertical than most...

It also looks like there aren't a lot of mechanical bits in the center under-seat area, I'm wondering what would happen if one tried to graft that seat mechanism onto a BM-3 style chassis????

It would likely bankrupt you?

But it may work. They dont stand you vertical for reasons of chair stability, or body stability. I have a tilt table here thats much the same as a standing chair. The thing will go to 90 degrees. But the last 5 or 10 feel really unsafe!

They put me on a tilt table in rehab a couple of times, and they also did one of the "Locomotor" machines which was really strange to be in... I didn't get to full vertical, but felt fine as far up as they'd let me go, and wanted more...

I can understand the idea of not wanting to overbalance the chair and flip forward, but AB's can stand at 90* w/o face-planting, and they don't have a few hundred pounds of chair hanging off behind them... I would think that if the footplate was behind the front casters (at least when standing) or had some extra support wheels (anti-tips?) on it, then it ought to be possible to at least stand at 90* and maybe even lean forward some...

Interesting.... Has a few things I like, some I'm not so sure about.

Biggest thing I'm not sure about is that I saw some Linak labels on the actuators - I have not been impressed by Linak's stuff any time I've encountered it - seems to not be very robust, making critical parts out of plastic, and so on. Also Linak tech support is very non-helpful - they won't sell to retail customers, and they won't give any info on their products like force outputs and the like... Just refer you back to the (overpriced) original maker...

I did like the way the standing moved you back so that the front casters act as anti-tips to some degree, though it did keep the space for batteries pretty small....

Would be fun to do a head-to-head against my Redman once I get it back together....

Please forgive my ignorance. The chair is stable when working in the seated position, am I correct? If so why do you have to operate it in the standing position when moving about?

Sure, I would love to be able to stand up and walk about, I have to admit to myself I no longer can do that!!!! I can stand for a short period, But then I have to sit back into my chair to get from place to place. It is a given!

However, given these restrictions, do the batteries have capacity enough to do this time after time all day. If not why not concentrate your efforts in that direction? I think Goose is onto the right correction, use Lifepo batteries. If you can fit series 24 batteries in the given space they are worthy of consideration as well. Just how much power storage do you require to make this optimal or practical?

it sounds like yours is the previous version to mine. :-DI did like that wheelchair, it is so tiny it could get in anywhere. But yes, it did tend to tip when going up an incline. However, I was used to it, and the wheels on the back always made it safe. but I concede, it was disconcerting,more for the family than myself. You could even get it to tip with a fast acceleration, which I made use of for curbs et cetera. LOL loved it.

However, it also had another problem, that it would stand up and then every now and again it wouldn't sit down. It would get stuck in the standing position, or part way down. So I argued under the sale of goods act the product was not fit for purpose and it demanded a refund. They offered me a brand-new wheelchair, the new model, so I took it.

My solution with the battery problem has been to fit lithium batteries. Expensive but it has done the trick.

Lithium is the only solution to the small batteries fitted to standing chairs. In fact its the only sensible battery to fit for at least 5 or 6 years. Its works out cheaper long term, and for about double the usable Ah we get freom lead. Lead is dead. Just massive heavy useless bricks with a short life. Its about time the wheelchair manufacturers figured this out, much like the rest of the world already did.

if you like that have look at this one (i think it also comes in rear wheel configuration)

I tried one a few months back. The standing is not really my cup of tea but it was ok and what is more it gen get you standing from any position including when you are laying flat on your back. It does go 10km per hour but i did not get to test the range but i would really doubt their claims or at least divided them by 3. Was comfortable and versatile but price was a killer. With all the options nearly 20000 euros. A very good semi luxurious car.
