Analysis:
The system of notches holding the hanging hinged constraint arm (like the Gym bench #1) works well to allow the 3 desired positions for the butterfly wings. The notches also look like an exciting climbing ladder for kids. However, the rigid hanging constraint arm might prove a safety issue for the scale of the installation.
