Working on a Lever Powered Assistive Mobility Drive for a Common Manual Wheelchair - INVACARE EX2 - Have explored several means to “Catch/Release” the 9 spoke Wheel to permit selective FWD/REV direction -in an oscillating rowing pattern.
Concept would be similar to a Mountain Bike front Disk Brake mounted on a Rowing Handle.
QUESTION: Can I get the same ON/OFF, “Gripping Action” with a P-PUMP Tube and a Fluid Control Valve?
BTW: I use Autodesk INVENTOR 2017 and can import Solidworks, Sketchup and AutoCad
To confirm, you’re looking to convert the wheelchair into one which uses a rowing motion (forward and backward) and use this same motion for forward and reverse motion? Normally we cannot provide design / consultation services, so perhaps you might want to explain in a bit more detail so other members of the community can offer their insight.
Yes. You get the picture exactly
My ideas will be Open Source - not profit or patent
My concern is the holding capacity of the Stalled Pump Rollers to provide Drive Lever lock up if fluid flow is Blocked Intermittently in either direction?
Honestly good question, and not sure. If it was my project, I’d need to experiment a little. Hard to provide a theoretical answer.
