PATENTS FOR SAFE FAST SHOOTING (a.k.a. SFS)?

[pjk9hp]

I was looking for the phrase "Safe Fast Shooting" in the English translation within the patent but couldn't find it. It just say "The present invention relates to an improved pistol."  However, by looking at the schematic drawing, one can readily see the SFS configuration.

Having the chance to speak to Leon Hubert and he buying us lunch was the highlight of our visit in Belgium.

And this is the patent info for the SFS we are all familiar with...

Hi slav,

Thanks so much for the other patent reference of SFS.
Not sure how these patents are interrelated or worked with each other or what.  The US patent 6539658 has cited reference to US4312263 of Jan 26, 1982 (translated from Bourlet's European patent EP0013583B1 of July 23, 1980). So who's the first real inventor? 

Regards...

Obviously, the patents you've shared are much earlier than the ones I knew about. Interesting, have someone here ever seen a gun equipped with this early version of SFS system? This first system as far as I can read the drawings is much more complex. The additional "catching lever" will have its influence on the trigger pull, it will be uneven and probably heavier. The additional spring 39 is on a very interesting place and how is it installed remains mystery for me. Interesting system...though.
