Yeah, my focus wasn’t the art here, so don’t mind the small artistic details. It’s really just to illustrate the design of the Wheel-Harness - an alternative to a wheelchair. Harder to put on and off, but also it’s a bit more lightweight, mobile, etc.

My attempt to turn this into a working design. I saw it and thought; “I must put my engineering-ness to good ’cause!”

Description of the Harness:

[Note: On main illustration, a few elements (Wheel Bar, Sock Strap and Foot Strap) are made transparent for easier viewing. The other 4 illustrations show progressively higher layers. Note on Illustration 1, the foreleg is cleared from view to illustrate the Rear Leg Strap.]

The buckles (Main Fig.) allow for easier application. Once undone, the harness can be lowered onto the pony, then buckled securely in place, before the legs are moved (by hoof) through the various straps which are then tightened.
Horizontal Body Strap (Main Fig.) provides horizontal force on the Flank Joint (Main Fig.) to keep it in place.
The Vertical Body Straps (Fig. 1) provide vertical force to keep the harness from sliding down.
The Rear Leg Strap (Fig. 1 and Main) and Knee Strap (Fig. 2) hold the knee in place, and keep the Flank Joint from sliding upwards. - The Rear Leg Strap runs up the back of the leg, and attaches to the Horizontal Body Strap on the back of the leg.

NOTE: The rear buckle is directly on the rear.
The Ankle Strap (Main Fig.) keeps the Knee Strap from sliding up. The leg’s weight keeps it from sliding down.
The Foot Strap (Fig. 3) is lowered under both feet. It attaches to the Body Joints (Fig. 1) on both sides. It keeps the hind legs raised so as to not drag on the ground.
The Sock Strap (Fig. 3) keeps the legs from rotating clockwise (from this viewpoint) by keeping the feet from moving forward.
The Wheel Bar (Fig. 4) is anchored to the Flank Joint, which resists rotational motion due to the various straps and weight from the Knee Strap and Rear Leg Strap.
The Knee Joint (Main Fig.) is spring-loaded, providing suspension for the wheel.

Also, I did have the presence of mind to make the design to make… Certain things easier, that parapalegics have to deal with So that they don’t require removing the entire assembly to do certain things.
