Abstract

FIELD: weaponry, in particular, small arms having a magazine with a two-row arrangement of cartridges. SUBSTANCE: the small arms has a frame and a barrel and a magazine with a two-row arrangement of cartridges installed in it, having wings. The novelty is in the fact that the inner surfaces of the magazine wings are made at an angle to the respective side wall of the magazine determined by formula: α = arctg(L-d)/2Z, where α - the angle on inclination of the inner surfaces of the magazine wings to the respective side wall of the magazine; L - the width of the magazine inner cavity, mm; d - the diameter of the cartridge in its bottom part, mm; Z - the distance from the cartridge bottom part installed in the magazine wings on the rimming line to the point of intersection of the bore line with the plane of the breech face, mm. EFFECT: enhanced stability of weapon operation. 4 dwg

Description

 The invention relates to weapons technology, namely to small arms having a magazine with double-row cartridges.

 Known gun model GSH-18, which uses a magazine with a double-row arrangement of cartridges (see the magazine "GUN GUN", N 6, 2000, S. 52).

 Also known is the pistol model MP-446 "VIKING" (see passport "Sport-training pistol MP-446" VIKING ", p. 8-10). In the store of the famous pistol, taken as a prototype, cartridges located on the sending line in the wings of the store are arranged in two rows.

 A disadvantage of the known devices is that the cartridge placed in the wings of the magazine, sent to the chamber, is not directed to the barrel in any plane. When retooling, the cartridge, encountering obstacles in its path, turns around and heads them into the chamber. In this case, the cartridge may be stuck, causing a delay in the supply of the cartridge to the chamber, i.e. weapon failure. In addition, when the cartridge is turned towards the chamber, accelerations depending on the feed rate of the cartridge act on the cartridge. Therefore, the rate of rotation of the cartridge, and hence the angle of rotation and its direction, depends on the speed of the feed unit (for example, the shutter). Thus, the instability of the feed mechanism can lead to the sticking of the cartridge and to other delays.

где α - угол наклона внутренних поверхностей крылышек магазина к соответствующей боковой стенке магазина;
L - ширина внутренней полости магазина;
d - диаметр патрона в его донной части;
Z - расстояние от донной части патрона, установленного в крылышках магазина на линии досылания, до точки пересечения оси канала ствола с плоскостью казенного среза ствола.The essence of the claimed invention lies in the fact that in small arms containing a frame and a barrel and a magazine with double-row cartridges installed in it, having wings, the inner surfaces of the wings of the magazine are made at an angle to the corresponding side wall of the magazine, determined by the formula

where α is the angle of inclination of the inner surfaces of the wings of the store to the corresponding side wall of the store;
L is the width of the internal cavity of the store;
d is the diameter of the cartridge in its bottom;
Z is the distance from the bottom of the cartridge installed in the wings of the magazine on the line of delivery, to the point of intersection of the axis of the barrel channel with the plane of the breech section of the barrel.

 Using the claimed invention will increase the stability of the weapon.

 In the claimed design, the cartridge located on the sending line is turned towards the chamber by the inner surface of the wings of the magazine and when being sent into the chamber it does not encounter obstacles or the obstacles encountered have a slight effect on it. In addition, the claimed design significantly reduces the influence of the speed of the feed mechanism (shutter) on the dispensed cartridge (due to a decrease in acceleration). All this allows to avoid sticking of cartridges sent to the barrel chamber.

The invention is illustrated by drawings, which depict:
in FIG. 1 - General view of the inventive device (the cartridge is on the line of sending);
figure 2 is a section aa in figure 1;
figure 3 is a view along arrow B in figure 1;
figure 4 - arrangement of cartridges in the store.

где L - ширина внутренней полости магазина (фиг.4), мм;
d - диаметр патрона в его донной части (фиг.4), мм;
Z - расстояние от донной части патрона, установленного в крылышках магазина на линии досылания, до точки 7 (фиг.1) пересечения оси 8 канала ствола с плоскостью 9 казенного среза ствола.Small arms contains a frame 1 (Fig. 1), in which a barrel 2 and a magazine 3 are placed. The wings 4 (Fig. 3) of the magazine guiding the cartridge located on the supply line to the chamber have an inner surface 5 (Fig. 2), made at an angle α to the side wall 6 of the store 3. The angle is calculated by the formula

where L is the width of the internal cavity of the store (figure 4), mm;
d is the diameter of the cartridge in its bottom (figure 4), mm;
Z is the distance from the bottom of the cartridge installed in the wings of the magazine on the delivery line to the point 7 (Fig. 1) of the intersection of the axis 8 of the barrel channel with the plane 9 of the breech section of the barrel.

 The device operates as follows.

 When feeding a cartridge mounted on the line of sending, the wings direct it into the chamber at an angle that excludes the possibility of sticking the cartridge on any part of the weapon. Following this, another cartridge in the store rises to the line of dispatch and turns its wings towards the chamber.
