I created a 3D printer model of an automatic coupler (Shibata type).
Among the automatic couplers in the same technical lineage as the Janny type coupler, the type that was improved in Japan is called the Shibata type automatic coupler.
This type of coupler is mainly used on locomotives and freight trains in Japan.
I was only able to obtain a simple three-view drawing, so some parts were inferred from online images, videos, and the appearance of the actual thing.
Although it uses parts with complex shapes, I think the structure is simple and very well thought out.
