Redesigned Wheelchair Offers Easier Storage in Aircrafts
Global, Transportation, February 18 2021
Back in 2018, we heard about a full-size foldable wheel known as the Revolve. Its inventor, Andrea Mocellin, has now incorporated the technology into a wheelchair that folds down to fit inside an airliner’s overhead baggage area.
The wheel itself features a central hub, six folding aluminum structures that take the place of traditional spokes, and an aluminum rim that’s divided into six interlocking sections – each of those sections is clad in a length of foam-filled tire.
The resulting package, which is definitely more compact than a regular wheel, could best be described as a cylinder that bulges out in the middle.
Mocellin’s latest invention, the Revolve Air wheelchair, incorporates two such 24-inch wheels joined side-by-side along a shared axle. A capsule-like component houses both wheels when they’re folded down. When it’s time to use the wheelchair, the capsule is removed, the wheels are opened up, then the capsule is placed back onto their axle, where it serves as the seat. A telescoping frame with a small set of front wheels on the end then folds down from the underside of the seat/capsule.
According to Mocellin, the Revolve Air can be folded and unfolded in about the same amount of time as is required for a traditional folding wheelchair. Unlike them, however, its size is reduced by 60 percent when folded. This means that it could easily be brought aboard aircraft and stored as overhead carry-on luggage. It could likewise be carried aboard trains and buses, or tossed into the back of a compact car or a taxi.
“The wheelchair project is now seeking business partners to produce a limited series of wheelchair, in order to be tested by active wheelchair travellers,” Mocellin tells us. “The whole project had been developed and prototyped in house with low costs of production […] Further development with potential partners would be to focus on maintaining the lightweight frame and maintaining a democratic price to be affordable by potential users.”
He adds that the first prototypes should be ready for testing and certification by 2022. An initial batch of production wheelchairs may subsequently be priced somewhere around €2,000 each (US$2,422), although that figure is still very much an estimate. Users might also be able to rent the chairs as needed, from kiosks at locations such as airports.
