How does it work?
The system is prepared by placing the shirt between the two resting claws. Then, Elsa drives up
to the Shirt Horn which is clamped over the door and swings her arms, one at a time, into the
shirt and moves them through the arm holes. After that, Elsa leans forward, placing her head
through the neck hole (as shown in Figure 7), and pulls on a rope in front of her, lifting up the
dynamic claw and releasing the shirt and completing the process.

Door assembly
Design Concept
The door assembly is an invertedU shaped aluminum structure shown in Figure 8 which fits
over the top of the door for support and includes wooden supports which extend down the face of
the door with extension points to attach the Shirt Horn and pulley system. The lower end of the
door assembly includes two simple armrests which extend out of the face of the door as seen in
Figure 9.
