An idea of going up curb

[sowseng]

Can we design and made something that helps going up and down curb?
Going up is difficult, going down is not comfortable, illustrate a simple design, do you think this will work?

I cant get up even little curbs.

Are you strong enough Sowseng to do that?

For 5" curb, I don't think so.

Moving forward you can use speed to go up the curb, I don't see how you could go fast backward.
If you don't go fast enough, you'll tip forward and you'll hurt yourself more as you will fall from the curb.

This idea doesn't mean to go fast

Hey, that's cool! I have theorized about mini wheels in front that could be used....yknow kind of like the Ibot's wheels did go up and down? To lever a manual chair up a curb. Like some kind of powered attachment, that coudl do stairs? Or maybe even manually operated, with some kind of greared or spring loaded system to reduce the force the user had to exert to get up the curb. Hmm, they'd need to be on front and back for balance going up stairs..... I might make a drawing.

Can't wait your drawing.

To withstand the stress of an average person's weight across that moment arm you would need some fairly strong (i.e. heavy or expensive) materials. Also for you to get up say a 5'' curb with a reasonable amount of strength you would have to be leaning backwards so for a 5'' curb those wheels to be effective that means they would probably have to be 10'' above the pavement when the chair was in a normal position, leaving you leaning in a very precarious position once you got up the curb.

Well...it would all be theoretical. Hopefully an actual engineer of some sort would take up the idea (if it ever got past this stage of speculation) so it would actually fly. :P I imagine that either steel, (maybe Al?) or titanium would work well for this. It would of course, have to be very sturdy... But also construction design, yknow like how the geometry of an object can make it much stronger than it would other wise be. Not just matterials count, but how they are configured, and the physics of a design, when it comes to loadbearing lthough they are clearly very important.

Looking at your pictures it looks nearly identical to the rollerblade wheels on anti tipper mod for curbs, except with those you go up the curb facing forward instead of backward. And the fact people are currently already using the rollerblade mod....
