Definitions

  • the present invention relates to an arrangement for a weapon comprising a countermass for reducing the pressure around the weapon, the countermass being enclosed in a container, which is mountable in the barrel of the weapon behind an ammunition part, such as a projectile or shell, and comprising an openable cover with break indications on the ammunition part side and an openable bottom with break indications on the other side.
  • an ammunition part such as a projectile or shell
  • the opening operation of the bottom depends on the temperature of the weapon or the countermass container.
  • the operating temperature can vary between approximately -40°C and +63 °C.
  • One object of the present invention is to provide an arrangement for a weapon with a countermass container, which brings about an improved symmetrical opening operation with favourable recoil in a better way than before.
  • the folding support is provided by means of an annular element configured to fit tightly against the outside of the countermass container and in agreement with the break indications of the openable bottom.
  • the openable bottom is designed with a number of openable flaps and said annular element comprises a support member for each openable flap forming part of the bottom.
  • annular element with a support member for each openable flap enables the opening area in the bottom of the counter mass container be defined by folding edges formed by each base of the opened flaps as in contact with the corresponding support members.
  • each openable flap might be triangular and in the open state configured with free equilateral legs and a base region integral with the wall of the countermass container.
  • Fig. 1 is a perspective view of an arrangement 2 for a weapon with countermass container comprising a sleeve 4, in one end of which a guiding folding support 6 is configured by means of an annular element 8.
  • said sleeve 4 is configured as a lining or casing for the counter mass container, which is mountable in the sleeve 4.
  • Fig. 2 is a perspective view of the sleeve in fig. 1, in which a counter mass container 10 of a conventional kind is mounted.
  • said container is configured with an openable bottom 12 by means of eight evenly distributed brake indications 14.
  • eight openable flaps 16 are defined in said openable bottom.
  • Fig. 3 and 4 are end views of fig. 1 and 2 respectively.
  • Fig. 3 illustrates the circumferential extension of the annular element 8 and particularly it illustrates an assembly of eight separate support members 18 integrated in the annular element.
  • One support member 18 is allocated for each openable flap 16 forming part of the bottom 12 of the container. Further, it is evident that each support member 18 is configured with a straight folding line 20, which constitutes a chord of the annular element 8 and is located at a distance d 1 from the centre line c.
  • Fig. 5 shows a variant of fig. 4 having a counter mass container with four openable flaps mounted in the sleeve.
  • said container is configured with an openable bottom by means of four evenly distributed brake indications 14'.
  • four openable flaps 16' are defined in said openable bottom.
  • Fig. 5 illustrates the circumferential extension of the annular element 8' and particularly it illustrates an assembly of four separate support members 18' integrated in the annular element.
  • One support member 18' is allocated for each openable flap 16' forming part of the bottom 12' of the container.
  • each support member 18' is configured with a straight folding line 20', which constitutes a chord of the annular element 8' and is located at a distance d 2 from the centre line c.
  • the configuration with four support members 18' will result in a relatively small opening area a 2 in the bottom 12' of the container. The smaller the number of support members the smaller is the area of the opening in the bottom.
  • Similar advantages are achieved as in the embodiment with eight openable flaps as illustrated in fig. 4. The fact is that such a small number as four openable flaps 16' even implies a greater risk, as each folding line 20' is proportionately longer and thereby more sensitive to be broken in pieces than in the embodiment with eight flaps.
  • Fig. 6 illustrates the rear part of a weapon comprising a barrel 24 accommodating an ammunition part with a projectile, shell or the like (not shown) and the countermass container arrangement 2 sectioned through lines A 1 - A 1 ; A 2 - A 2 .
  • the annular element 8 is configured at one end (the rear end) of the sleeve 4, which is arranged to interact between the counter mass container 10 and the barrel 24.
  • the counter mass container 10 is mounted in the sleeve 4 with each support member 18 of the annular element located close to the corresponding base region 22 of each flap 16 in the openable bottom 12, which base region is integral with the wall of the countermass container 10.
  • Fig. 7 is a detailed section view on a larger scale of a representative bottom part of the container arrangement in fig. 6, which illustrates in dashed lines one flap 16 in its open state.
  • the sleeve 4 including the appropriate support member 18 integrated in the annular element 8 has an outer diameter DS and is supported by the barrel 24.
  • the flap 16 has been bent open to its open state by influence of the counter mass. It appears that the flap 16 has been bent over the support member 18 and the material of the flap in a hinge part in abutment against the support member 18 has been deformed to such an extent that its free end 26 is located close to the barrel 24, whereby a folding edge 28 is formed of said material in abutment against the support member.
  • said folding edge 28 would be located a distance from the inside of the barrel 24, approximately the same as the outer diameter Ds of the sleeve 4, which determines the actual location of the folding line 20, which in turn depends on the number of flaps chosen, compare distance d 1 in fig. 4 with distance d 2 in fig. 5 from the centre line c.
  • d 1 ,d 2 or any optional such distance the thickness of the material in the flap should be added, which would result in a distance da from the centre line c.
  • the actual distance da is the decisive design parameter for defining the opening area a 1 , a 2 of the container.
  • the described embodiments are disclosed with eight or four openable flaps only as non delimiting examples. Variants having different numbers of flaps are allowed within the scope of the invention.
