Device for preventing the tensioning of a firing pin spring in the disarming of a hammerless self-loading pistol provided with a lock slide and a self-loading pistol with such a device
The invention relates to a device for prevention of the tensioning of a firing pin spring in the disarming of a hammerless self-loading pistol ( 1 ) provided with a lock slide ( 7 ), wherein the device can assume a disarming position and a locking position, with: a spring-loadable firing pin ( 17 ) with a lug ( 17 a ) formed on it for active engagement with a sear ( 19 ), which in the cocking position for cocking the firing pin spring protrudes into the path of motion of the lug ( 17 a ) and in the disarming position is disengaged from the lug ( 17 a ), a trigger bar ( 27 ) coupled with a trigger which in the disarming position disengages the sear ( 19 ) from the lug ( 17 a ), and is characterized by a disarming shaft ( 15 ), which in the disarming position enables a movement of the trigger ( 5 ) and thus the trigger bar ( 27 ) to the front, and a disconnector bar ( 21 ) that can be coupled to the trigger bar ( 27 ), said disconnector bar being impacted in the disarming position by the lock slide ( 7 ) moved to the front and as a result operatively disengaging the sear ( 19 ) from the lug ( 17 a ) by means of the trigger bar ( 27 ). The invention also relates to a self-loading pistol equipped with such a device.
1. A device for prevention of the tensioning of a firing pin spring in the disarming of a hammerless self-loading pistol provided with a lock slide, wherein the device can assume a disarming position and a locking position, the device comprising:
a spring-loadable firing pin with a lug formed thereon for active engagement with a sear, wherein in the locking position for cocking the firing pin spring the sear protrudes into the path of motion of the lug and in the disarming position the sear is disengaged from the lug,
a trigger bar coupled with a trigger which, in the disarming position, disengages the sear from the lug,
a disarming shaft, which in the disarming position enables movement of the trigger and thus the trigger bar to the front, and
a disconnector bar that can be coupled to the trigger bar, said disconnector bar being impacted in the disarming position by the lock slide moved to the front to operatively disengage the sear from the lug by the trigger bar.
2. The device according to claim 1 , in which a stop is provided on the trigger and wherein the disarming shaft has a section with reduced diameter that at least partially receives the stop in the disarming position in the event of a rotated disarming shaft.
3. The device according to claim 2 , in which the section with reduced diameter is a recess that is wedge-shaped and, in its locking position, prevents a movement of the stop and thus movement of the trigger as well as of the trigger bar to the front.
4. The device according to claim 1 , in which the forward movement of the trigger bar enables its forced engagement with the disconnector bar and the sear.
5. The device according to claim 4 , in which the trigger bar comprises at least one tab for the forced engagement.
6. The device according to claim 4 , in which the sear has a projection for the active engagement with the trigger bar.
7. The device according to claim 4 , in which the disconnector bar has a step for the active engagement with the trigger bar in a recess.
8. The device according to claim 1 , in which the disconnector bar has an elevation on its side facing the lock slide and can be impacted upon through a lower contour of the moving lock slide.
9. The device according to claim 8 , in which the lock slide has on its underside a first recess, which in the case of a closed lock can be brought into active engagement with the elevation of the disconnector bar.
10. The device according to claim 9 , in which the lock slide has on its underside at least a second recess which in its slide catch position can be brought into active engagement with the elevation of the disconnector bar.
11. The device according to claim 1 , in which when the disarming shaft is in the disarmed, a non-recessed region on the underside of the lock slide, in its forward movement from its slide catch position, presses the disconnector bar down, said disconnector bar in the process going into form-fitting or forced engagement with the trigger bar, bringing said trigger bar into form-fitting or forced engagement with the sear and the trigger bar brings the sear out of the path of motion of the firing pin.
12. The device according to claim 1 , with a release pawl, which upon actuation of the trigger can be coupled with the trigger bar and thus disengages the sear from the lug to discharge a round.
13. A self-loading pistol with a firing pin prevention device for its disarming, comprising:
a device for prevention of the tensioning of the a firing pin spring in the disarming of a hammerless self-loading pistol provided with a lock slide, wherein the device can assume a disarming position and a locking position, the device comprising:
a spring-loadable firing pin with a lug formed thereon for active engagement with a sear, which in the locking position for cocking the firing pin spring, the sear protrudes into the path of motion of the lug and in the disarming position the sear is disengaged from the lug,
a trigger bar coupled with a trigger which in the disarming position disengages the sear from the lug,
a disarming shaft, which in the disarming position enables a movement of the trigger and thus the trigger bar to the front, and
a disconnector bar that can be coupled to the trigger bar, said disconnector bar being impacted in the disarming position by the lock slide moved to the front and as a result operatively disengaging the sear from the lug by means of the trigger bar.
