  • Patent number: 9863728
    Abstract: A cylinder breech block device (100) of a repeating firearm has a breech block cylinder (200) pivoted in a system housing (160) of the repeating firearm for execution of repetitive action thereof and capable of being locked to said system housing (160) for firing a round. A firing pin (140) capable of being cocked by a tension spring is mounted for linear displacement in the direction of a cartridge (141) stored in a magazine (141) of a barrel (143). Cocking of the firing pin (140) is effected by causing rotation, through a predefined angle, of a breech bolt handle (300) rigidly connected to a tension crown ring (400) that is pivoted on a central shaft (210) of the breech block cylinder (200).

  • Patent number: 8997623
    Abstract: A locking block device (100) provided in the region of a cartridge chamber (121) of a handgun barrel (120) has a locking block (110) for releasably locking the barrel (120) to a breech prior to firing, and has a control member (111) having a control guide (112) for swinging out the barrel (120), after firing, for the purpose of separating the barrel (120) from the breech, and further has a feed ramp (140) formed in the region of a stop member (130) of the locking block (110) for feeding a cartridge, stored in a magazine of the handgun, into the cartridge chamber (121) following ejection of a fired cartridge. A modular design capable of being adapted to meet specific requirements is achieved in that the feed ramp (140) is formed on a ramp member (150) capable of being separated from the locking block (110) and releasably locked to the locking block (110).

  • Patent number: 7610709
    Abstract: An antidismantling device for preventing dismantling of a hand-gun when a cartridge is present in the barrel (102) of the hand-gun, the barrel (102) being mounted in a breech block (110), and a guide pin (123), which is biased at least indirectly in the direction of the longitudinal axis of the barrel (102), is slidably mounted in a bearing (113) in the breech block (110), and one end of the guide pin at least indirectly abuts a contact surface (121) for making contact with part of a cartridge (101), and the position of the guide pin in relation to the breech block (110) when a cartridge (101) is present in the barrel (102) differs from the position thereof assumed in the absence of a cartridge (101) in the barrel (102) is created in that the guide pin (123) interacts at least indirectly with a safety mechanism (141) provided on the grip of the hand-gun in order to prevent dismantling of the breech block (110) when a cartridge (101) is present in the barrel (102) of the handgun.

  • Patent number: 5701698
    Abstract: In a hammerless automatic pistol with double-action and single-action functions there are provided between the trigger arm and firing pin of the trigger mechanism a catch pawl for the firing pin and a support lever that maintains the catch pawl in the catch position. During double-action operation, both of these intermediate components are disengaged but they are engaged for single-action function. The engagement and disengagement of these intermediate components is performed automatically during the shooting cycle. By merely removing one or both of these intermediate components the automatic pistol can be modified for double-action only trigger function, in which the firing pin is simultaneously cocked and released for firing during each shot by actuating the trigger.
