Don’t spend hundreds of pounds on mechanised arrays when you can solve the actual problem for 20p.
I was unable to go out on my own because my chin controller would randomly swing away if I went over an unexpected bump, leaving me helpless.
Andrew drilled a hole through the swing-away arm, pushed in a 20p lynch pin and secured it with a cheap carabiner keychain. Achievement unlocked.
Take a drill and a 4.8 mm drill bit, and a lynch pin.
Drill a hole straight through the swing-away arm through the bottom latch piece as shown.
Take your lynchpin and push it through the hole, so the large head abuts the flat edge of the top (notched) latching piece and stops it swivelling, remembering to marvel at your new found swing-away arm stability.
For added security we bought a keyring type chain for about 99p. It is pretty much like any of these chains and I think any will do.
If you have a “lift to swing” chin controller array, you’ve probably had this problem too: you’re crossing a road and you bump down the curb or over a pothole. The impact jumps the swing-away latch up and the whole edifice swings smoothly away from your face, leaving you in the middle of a busy road unable to move. Arrrgh! Having to be rescued whilst out alone on my trusty steed because the arm that holds my chin controller kept swinging away was getting embarrassing. Andrew’s ingenuity, a drill, drill bit, a lynchpin and a chain solved all that and cost way less than I was quoted from multiple wheelchair dealers.
If you get a chain, you need to attach one end to your lynchpin and the other to your wheelchair, obviously. Mine already had a nearby cutout that I used, but if you don’t, you can always secure the chain with sugru.
That’s it, you are fully stable and you can now Go West Young Man on your own, safe in the knowledge that you will no longer need to be rescued by old ladies and teenage girls whilst out in the park.
This is all undertaken at your own risk, obviously.
