Definitions

  • the closure head 9 shown in a perspective view comprises a substantially cylindrical base body 17 which has on its front side a ram plate 18 which is perpendicular to a longitudinal axis of the base body 17 and on its rear side a Figures 3 and 5 visible, inwardly curved guide surface 19 for guiding the pivotable locking elements 15.
  • the two opposite recesses 14 for the positive engagement of the front ends 13 of the two plate-shaped holding elements 8 are arranged.
  • the locking head 9 also contains a border 20 that surrounds the impact base 18 in a ring shape, which in the embodiment shown is formed by two semi-annular border parts 21 and 22 detachably arranged on the front of the base body 17.
  • the two diametrically opposed upper and lower half-shell-shaped locking elements 15 are pivotally mounted about the common transverse axis 16 in aligned transverse bores 23 of the two plate-shaped holding elements 8.
  • the two locking elements 15 have two diametrically opposed flattened areas 24 on their outer side with outwardly projecting semi-annular bearing pins 25.
  • the upper locking element 15 rests with its two diametrically opposed bearing pins 25 on the upper inner wall of the two aligned transverse bores 23, while the lower locking element 15 rests with its two diametrically opposed bearing pins 25 on the lower inner wall of the two aligned transverse bores 23.
  • the locking elements 15 are held pivotably on the two plate-shaped holding elements 8 by means of the pins 26 inserted between the bearing pins 25.
  • the half-shell-shaped locking elements 15 have a front part 27 that projects forward relative to the bearing pins 25 and a rear part 28 that projects rearward relative to the bearing pins 25.
  • the front contact surfaces 29 of the locking elements 15 are matched to the rear guide surface 19 of the bolt head 9 in such a way that the locking elements 15 are guided on the rear guide surface 19 of the bolt head 9 during their movement between the release position and the locking position.
  • a sleeve-shaped control element 35 Arranged between the two half-shell-shaped locking elements 15 is a sleeve-shaped control element 35, which is coupled to the bolt handle 3 for axial displacement and controls the movement of the locking elements 15 between the locking position and the release position.
  • the sleeve-shaped control element 35 has, at its front end, a front support region 36 designed as a radial extension for moving the locking elements 15 into the locking position and a rearwardly offset, ramp-shaped rear support region 37 for moving the locking elements 15 into the release position.
  • the bolt head 9, shown in a perspective view, is shown in various views with the essentially cylindrical base body 17.
  • the base body 17 has on its front side a breech face 18 which is perpendicular to a longitudinal axis of the base body 17 and on its rear side an inwardly curved guide surface 19 for guiding the pivotable locking elements 15.
  • a central through-opening 42 for guiding a front end of the firing pin 41 is arranged in the base body 17.
  • two blind bores 43 are also arranged in the base body 17, open towards the front, for receiving pin-shaped cartridge ejectors acted upon by springs.
  • the closure head 9 also contains a ring-shaped border 20 surrounding the breech face 18, which in the embodiment shown is formed by two border parts 21 and 22 detachably arranged on the front side of the base body 17.
  • the base body 17 has on its front side a circumferential groove 22 which runs around the outer circumference and is inserted into the Figures 9 and 10 visible retaining groove 44 for the positive engagement of the two border parts 21 and 22.
  • FIG. 1 On the inside of the border parts 21 and 22, below the Figure 10 shown hook-shaped projections 47 in Figure 11 Visible positioning elements 53 for positive engagement with corresponding counter-elements 54 are arranged on the outside of the base body 17.
  • the positioning elements 53 are designed as inwardly projecting semicircular projections.
  • the counter-elements 54 are formed as semicircular recesses on the outside of the base body 17. A defined position of the border parts 21 and 22, secured against rotation, can be specified via the positioning elements 53 and the corresponding counter-elements 54.
  • the border parts 21 and 22, which serve to laterally limit the breech face 18, can thus be replaced with additional border parts adapted to the desired caliber when changing the caliber. Furthermore, by exchanging the position of the two border parts 21 and 22, the cartridge ejection direction can be easily changed. Complete bolt heads do not need to be provided for a caliber change or a change in the cartridge ejection direction. Depending on the caliber and cartridge ejection direction, appropriately adapted bolt heads can be easily assembled and assembled using a standardized base body. This can reduce the costs of changing the caliber or adjusting the cartridge ejection direction.
