Title is pretty clear I guess:
Icon_A5_in_wings-stowed_configuration.jpg

Sorry for ruining the layout, but this is the only clear picture I could find of it. Here's the link to the picture:

I can see the "triangle" pivoting around the vertical axis and with the wings "extended", rotating the horizontal axis, so that the wings aling. I can see the automatic connections for aileron and flaps and know how those work. I guess both "holes" in both wing and wing stub are used to carry the bending and drag loads and this is the first part I don't follow.

Any idea how this works? Are there pins that extend and then somehow prevent the wing not only from a vertical motion, but also from a horizontal one (wing drag force)?

I also don't get how they transfer the torsional loading of the wing. Both "holes" and the "double pivot" that the wing hangs onto are very close together. Something I'm missing?
