Apart from the post-war ones, some pre-war projects for such aircraft were already mentioned:
http://www.secretprojects.co.uk/forum/index.php/topic,11930.0.html
http://www.secretprojects.co.uk/forum/index.php/topic,11940.msg115696.html#msg115696
http://www.roadabletimes.com/roadables-integ_longobardi.html
and not to forget the Ushakov and Harrington http://www.secretprojects.co.uk/forum/index.php/topic,703.msg5406.html#msg5406

The already mentioned article in the "Fliegerkalender 2014" shows two more projects, one designed by
Paul De Asis (US-patent 2.162.066) and the other from Earl Brigs (US-patent 2.444.332). Both should fold their
wings backwards for diving, but while the De Asis draing at least seem to have sufficient wing area, Briggs gave
his vehicle hardly more, than slightly enlarged depth rudders.

The patent itself.
