Abstract
The present invention relates to an arrangement for improving shooting accuracy of a weapon comprising i) a barrel 13, ii) at least one component iii) a holding device mounted on said barrel 13, said holding device comprising means for holding 1a said at least one component allowing said at least one component to be displaced relative to and in parallel with the barrel and the means for holding from 1 mm to 200 mm during which displacement said at least one component does not absorb any substantial recoiling forces.
Claims
1. Arrangement for improving shooting accuracy of a weapon comprising a barrel; at least one component, said at least one component comprises a braking unit; a holding device mounted on said barrel, said holding device comprising means for holding said at least one component allowing said at least one component to be displaced relative to and in parallel with the barrel and the means for holding from 1 mm to 200 mm from a first position to a second position, during which displacement said at least one component does not absorb any substantial recoiling forces, wherein the at least one component reaches the second position after a projectile has left the barrel and the braking unit starts to absorb recoiling forces when the at least one component reaches the second position.
2. Arrangement according to claim 1, wherein said means for holding comprises at least one shaft along which said at least one component is displaced.
3. Arrangement according to claim 1, wherein said at least one component further comprises a sight.
4. Arrangement according to claim 1, wherein said at least one component is positioned prior to firing at said means for holding at a distance of from 5 mm to 20 mm from an end point of said means for holding.
5. Arrangement according to claim 1, wherein said at least one component includes a sight mounted on the braking unit.
6. Arrangement according to claim 1, wherein said at least one component is positioned from 5 to 15 mm from an end point of said means for holding.
7. Arrangement according to claim 1, wherein the braking unit is mounted on said means for holding allowing said braking unit to slide along said means for holding 2 to 20 mm without absorbing any substantial recoiling forces.
8. Arrangement according to claim 2, wherein the second position comprises an end of the at least one shaft.
Description
DESCRIPTION OF THE DRAWINGS AND THE INVENTION
(1) FIG. 1 schematically discloses a recoiling system comprising a holding device 11 which consists of a holder 11a; and a braking unit 11b comprising a disc spring package (not shown). FIG. 1 also shows a sight 12 which is axially displaceable upon firing relative to and in parallel with barrel 13 (projectile leaves barrel 13 in the direction indicated by F). After firing in direction F, the barrel 13 and the holder 11a are caused to move in the opposite direction due to recoiling forces (in this particular example) indicated by the arrow at the barrel 13. As the barrel 13 and the holder 11a are transported backwards relative to the firing direction, the braking unit 11b and the sight 12 are eventually contacted with holder 11a. The braking unit 11b starts to absorb recoiling forces in a controlled manner when such contact is reached with holder 11a. This absorbing action occurs after the projectile has left the barrel.
(2) FIG. 2 shows a holding device comprising an interface surface 5 which is mounted on a barrel (not shown). The holding device is secured by locking mechanism 3. The holding device comprises means for holding, shaft 1a, on which braking unit 11b is mounted, through hole 7. A sight 8 is in turn mounted on braking unit 11b (further shown in FIG. 4). As the projectile leaves the barrel, the braking unit 11b and the sight are still in its original position while the barrel and holding device have moved backwards. A certain period of time after the projectile has left the barrel, the braking unit 11b will reach an end point of shaft 1a of the holding device 11 and recoiling forces will be absorbed through the braking unit 11b comprising resilient springs. A retraction shaft 1b is provided at which a weak retraction spring 2 is arranged for retracting the braking unit 11b and sight to its original position after the recoiling forces have been absorbed. The retraction spring does not substantially influence the component such that it starts to absorb any substantial recoiling forces prior to the projectile has left the barrel. The braking unit 11b mounted on shaft 1a and sight 8 mounted on the braking unit 11b remain in a standstill position initially while the barrel and the holding device are moved backwards relative to the fire direction (in other weapons, other directions of recoiling forces may apply). As evident from the disclosure herein, the braking unit 11b and the sight 8 (or any other component as defined herein) may be described to be displaced relative to the holding device even though the holding device per se describes a movement (backwards) due to arising recoiling forces after firing while braking unit 11b and sight 8 are not initially moving. After contact with an end point of the means for holding (e.g. a shaft), the braking unit 11b and the sight 8, however, start to absorb recoiling forces until the system finally stops whereupon the retraction spring 2 brings the system to its original position. In FIG. 2, the firing direction is indicated by an F, the recoiling direction of the barrel by an R. FIGS. 3 and 4 show the holding device from different perspectives.
