Title: Latching arrangement for the firing pin in an explosive powder charge driven setting gun

Abstract: In an explosive powder charge driven fastening element setting gun, a barrel is displaceably mounted in a housing forward of a firing pin. By pressing the barrel rearwardly, it moves the firing pin into the cocked position. The firing pin is released from the cocked position by a latch which turns the firing pin about its axis. The latch includes a driving cam engageable with a lug extending laterally from the firing pin for rotating the firing pin. It also includes a return cam which guides the lug in its movement in its axial direction from the cocked position into the firing position.
