DETAILED DESCRIPTION

(7) The extractor device 100 according to the invention depicted in FIGS. 1 to 4 is mounted in a breech section 300 of a slide with an underpart with functional elements for interaction with an upper region of a grip part (frame) 200 of a firearm and contains an extractor 110 mounted rotatably about an axis of rotation with an extractor claw provided in the region of an end of the extractor 110 close to the barrel 210 (FIG. 5) of the firearm and a guide element 112 arranged in the region of an end of the extractor 110 remote from the barrel 210 of the firearm and interacting with an extractor spring 120 biasing the extractor 110, in order to limit a rotational movement of the extractor 110 by contacting a cartridge 400 newly supplied from a magazine. Thus the combined extractor 110, spring 120, and pin 112 form the extractor device or assembly.

(8) The guide element 112 in this case is biased in the direction of a control link 130 by an extractor spring 120 arranged in an inner bore of the extractor 110, said control link being configured in an extractor pocket 310 in the breech section 300 (e.g., cast) and forming a bearing of the extractor 110. The guide element 112 in this case is mounted in a reproducibly movable manner within the bore of the body of the extractor 110 in an axial direction of the bore.

(9) The control link 130 is configured as part of the inner boundary wall of the extractor pocket 310 formed in the breech section 300 and creating a bearing of the extractor 110.

(10) The guide element 112 is configured as a pressure pin (spring pin) 112, whereof the end 114 remote from the extractor spring 120 has a curved end face 1141, which is movably mounted in coherent fashion in a control link 130 configured as a pan 130.

(11) The pressure pin 112 has a cylindrical form, wherein the end 114 of the pressure pin 112 remote from the extractor spring 120 is configured on a shaper head part 115, the diameter of which is smaller by comparison with that of the regions 116 (FIG. 3) close to the extractor spring 120. FIG. 3 shows a shoulder at a junction of the shaper head part 115 and the region 116.

(12) The end of the pressure pin 112 close to the extractor spring 120 is provided with an axially oriented pin 117, the diameter of which is smaller compared with the remaining part of the pressure pin 112, so that the pin 117 can be introduced into the hollow of an open end 121 of an extractor spring 120 configured as a spiral spring.

(13) The extractor pocket 310 has a recess 311 as the bearing for a pedestal 119 projecting from the body of the extractor 110, whereof the undersurface 1191 remote from the guide element 112 stands opposite a bottom surface 3111 of the recess 311 close to the barrel, and whereof the front surface 1192 close to the extractor claw 111 merges with the undersurface 1191 in the form of a curved shaper head 140, wherein the shaper head 140 is supported both against the bottom surface 3111 of the recess 311 and against a lateral surface 3112 of the recess 311 close to the extractor claw 111 and opposite the front surface 1192 of the pedestal 119 and forms an axis of rotation of the extractor 110, which allows the extractor 110 to rotate in relation to the breech section 300.

(14) The axis of rotation of the extractor 110 and the attachment surface of the extractor claw 111 contacting a circumferential groove of a cartridge are arranged at the same distance from the central axis of the barrel.

(15) The shaper head 140 of the pedestal 119 is biased by means of the guide element 112 through the action of the extractor spring 120 in the direction of the lateral surface 3112 of the recess 311 lying opposite the front surface of the pedestal 119.

(16) When the extractor 110 is in an inoperative position, in which the extractor claw 111 contacts a cartridge 400 located in the cartridge chamber 220 of the firearm, the undersurface 1191 of the pedestal 119 is arranged at an acute angle to the bottom surface 3111 of the recess 311 lying opposite.

(17) This angle corresponds to the angle, about which the longitudinal axis of the extractor 110 pivots when the end face 1141 of the pressure pin 112 slides radially (relative to the barrel axis) in the pan 130 from one end 1301 of the pan radially remote from the barrel 210 to an end 1302 of the pan radially close to the barrel 210. FIG. 3 shows the ends as concave.

(18) The undersurface 1191 of the pedestal 119 of the extractor 110 remote from the guide element 112 and the front surface 1192 of the pedestal 119 of the extractor 110 close to the extractor claw 111 are arranged at an acute angle to one another, whereas the bottom surface 3111 of the recess 311 close to the barrel and the lateral surface 3112 of the recess 311 lying opposite the front surface 1192 of the pedestal 119, close to the extractor claw 111, are arranged at a right angle to one another.

(19) The exemplary embodiment of the invention explained above serves simply to provide greater understanding of the inventive teaching embodied in the claims, which is not limited as such by the exemplary embodiment.
