Abstract

In order to devise an inexpensive method for producing the breechblock (111) for a firearm that can resist a maximum of mechanical stress and is physically appealing, a metal blank (110) is pressed into a female die (130) representing a reversed copy of the outer contour (112) of the breechblock (111) by means of a male die (120) at a temperature ranging from ambient temperature to 760°C, said male die (120) applying a pressure ranging from 1000 to 8000 kN.

Abstract

In order to devise an inexpensive method (100) for producing a heavy-duty prefabricated breechblock (110) for a firearm, a substantially cuboidal metal blank (120) is compressed in a substantially hollow cuboidal female die (140) by means of a male die (130). The female die (140) has a profiled section (121) in the region of the surfaces contacting the blank (120), said profiled section (121) including a reversed copy of the outer contours (111) of a prefabricated breechblock (110).

Abstract

The invention relates to an interchangeable attachment element (100) for the grip piece (120) of a pistol that comprises a trigger (150) and a grip (160) in which a charger (130) with a charger base (131) can be inserted. The grip piece (120) comprises a front region near to the grip (161) and a rear region far from the grip (162). According to the invention, a rapid exchange is made possible by the fact that the front and the rear regions of the grip piece (120) each comprise at least one attachment element for interacting with a rear (102) and a front (103) attachment device of a grip attachment element (100) so as to attach the grip attachment element (100) to the grip piece (120). The rear region of the grip piece (120) comprises at least one eyelet device (123) that, when the grip attachment element (100) is placed on the grip piece, engages in a positive fit into a bore (101) of the grip attachement element (100), wherein a safety pin (140) can be detachably inserted into said bore in order to detachably connect the grip attachment element (100) to the grip piece (120).

Abstract

The invention relates to a key element (110) for locking a hammer or bolt weapon (100), comprising a trigger bar (120) that can be displaced in a reciprocating manner by a trigger. To clearly and directly identify at a glance that the firearm is locked, the key element (110) is configured as a detachable component that can be fixed to the firearm housing.

Abstract

The invention relates to a device (100) for indicating the presence of a cartridge (101) in the barrel (102) of a pistol comprising a breech (110), which contains the barrel. To provide at least one optical identification of the presence of a cartridge in the barrel of the firearm, an indicator element with a contact pin (122), which is provided with a contact surface (121) for making contact with part of the cartridge and is pre-stressed in the direction of the barrel, is contained in the breech in a reciprocating manner. When a cartridge has been inserted and is present in the barrel, the position of said indicator element in relation to the breech differs from the position adopted in the absence of a cartridge in the barrel. The indicator device also acts as a safety catch to prevent dismantling.

Abstract

The invention relates to a safety catch for preventing the dismantling of a pistol when a cartridge is present, said cartridge being inserted in the barrel (102) of a pistol that is located in a breech (110). In said breech (110), a guide pin (123) that is at least indirectly pre-stressed in the direction of the longitudinal axis (103) of the barrel (102) is displaceably mounted in a bearing (113), one end of which at least indirectly adjoins a contact surface (121) that makes contact with part of a cartridge (101). When a cartridge (101) has been inserted and is present in the barrel (102), the position of said bearing in relation to the breech (110) differs from the position adopted in the absence of a cartridge (101) in the barrel. To produce the safety catch mechanism, the guide pin (123) co-operates with a safety catch unit provided on the handle of the pistol (141), to prevent the dismantling of the breech (110) when a cartridge (101) is inserted in the barrel (102) of the pistol.

Abstract

The invention relates to a trigger device (100), for hammerless firearms, comprising a trigger bar (120) which may be moved in a reciprocating manner by a trigger (110) which is at least indirectly coupled to a stop piece (130), which holds a bolt (140) in a pre-tensioned first position in the rest position of the trigger (110) and releases the bolt (140) for a sliding movement into a second position in the firing release position of the trigger (110), whereby a precise definition of a repeating position for a trigger of a firearm provided with a bolt (140) may be achieved in that the first and second position of the stop piece (130) are defined by a support element (150) which is mounted such as to be displaced in a reciprocating manner between a first and a second end position, by means of a support displacer (160), coupled to the trigger bar (120) in order to bring the stop piece (130) into the second position thereof for a release of the bolt (140) in the second position thereof.
