Simple Adjustable Hinge Design

[ChrisDanger]

I'm looking to cheaply manufacture an adjustable hinge, to fix a wheelchair footplate upright to the main frame. Something like the Variloc hinge below looks great, but is expensive to buy, and is complicated to reproduce (with many small internal parts).

Does anyone know of some way to provide a similar level of adjustability with a simpler joint? I've spent some time looking around for inspiration but have not found anything really.

O.K. now that you have the practical solutions, I will propose a pair of hub unit bearings with the disk brakes attached. The speed sensors could be modified to apply the brakes at any foot pedal setting from the chair control panel. Jimmy will give the chair user a ride if this works.

Go look at how push lawn mowers set the height of wheels.
