Firing mechanism for use in a firearm having an electronic firing probe for discharging non-impact fired ammunition

摘要

According to the present invention, a firing mechanism adapted to discharge a non-impact fired ammunition cartridge in a revolver comprises a trigger, a hammer, a stirrup, a transfer bar, a link, and a rebound. The trigger is hung conventionally on a frame of the revolver and adapted for rotation to and from a firing position. The transfer bar is engaged with the trigger and configured for movement into and out of engagement with a firing probe during actuation of the firing mechanism. The hammer is coupled to the stirrup via the link such that the hammer and stirrup rotate in opposite directions. The rebound has a front end coupled to the trigger and a rear end which receives a main spring. The main spring is captured between the stirrup and the rebound to bias the trigger toward recovery and the stirrup and hammer toward their respective firing positions. Movement of the trigger toward the firing position simultaneously compresses the main spring between the stirrup and the rebound, thereby providing enough energy to drive the hammer against the transfer bar to effect contact and electrical discharge of the cartridge.
