Description

The technical field of the invention relates to receiver-drives for collecting and storing cartridge cases.

Known receiver-drives, which are typical for use with light firearms and which allow you to collect sleeves at shooting ranges. In US patent US5664727 describes this type of receiver-drive. However, this solution is not applicable directly to the site for small-caliber (caliber not exceeding 15 mm) or medium-caliber (caliber component from 15 mm to 50 mm) weapons.

In fact, a conventional weapon assembly contains a cradle on which the weapon is placed and which is pivotally mounted on pins attached to the machine, forming a fork. The trunnions provide a tip of the weapon along the elevation angle (vertical). Therefore, the axis of the pins is most often horizontal.

The machine itself is usually mounted rotatably with respect to the supporting structure, for example, a vehicle, ship or aircraft (aircraft). The axis of rotation of the machine provides aiming the weapon in azimuth. Therefore, this axis is vertical.

Finally, the weapon is installed in a known manner on the cradle with the help of the slide, which ensure the rollback of the weapon during shooting. Cartridge shells are automatically ejected by a weapon during firing. In known types of weapons, the window for ejecting cartridge cases is not always easily accessible and there is not always the space needed to place the receiver-drive in front of this window.

The international publication of patent application WO 2011/050905 thus describes a side reflector which is installed near the window for ejecting cartridge cases and which directs cartridge cases into the lower container. This device is typical for a specific weapon design, in which the window for ejecting cartridge cases is located close to the rear of the weapon and is accessible.

However, most often, the window for ejecting cartridge cases is located between the supports of the machine, and the receiver-drive cannot be placed in the immediate vicinity of the window for ejecting cartridge cases.

JP 2011169480 proposes various solutions in which cartridge shells ejected by a weapon pass through a tray in the direction of a storage receptacle that is located at some distance from the weapon. The proposed solutions are relatively complex and contain, in particular, mechanization tools that allow you to distribute empty cartridge cases inside the drive.

In fact, when the cartridge cases thus pass through the channel in the direction of the accumulator, there is a risk of the accumulation of these cartridge cartridges near the entrance to the receiver-accumulator. In this case, cartridge cartridges can block the input window for ejecting cartridge cartridges of the receiver-drive. They can subsequently block the feed channel and stop the firing cycle of the weapon.

The invention proposes a drive arranged so that it can prevent clutter of the input window of such a receiver-drive cartridge sleeves.

The solution proposed in the invention is simple and does not contain mechanization means or other mechanical element that may be defective.

Thus, the invention relates to a storage receptacle for collecting and storing cartridge cases, wherein the storage receptacle comprises a storage compartment into which the cartridge sleeves enter through a window formed in the front wall of the storage receptacle and intended to be placed in the direction of the cartridge discharge tray sleeves, the receiver-drive is characterized in that it contains at least one dihedral reflector, which is installed essentially facing the window and at a certain distance from it, and the two-sided This reflector contains two planes forming the first angle between them, and the intersection edge of the planes is additionally tilted by a second angle relative to the wall with the window.

According to one embodiment, the storage receiver comprises two dihedral reflectors mounted one on top of the other with respect to a geometric plane perpendicular to the front wall with a window and with an orientation substantially symmetrical with respect to this geometric plane.

According to an alternative embodiment, the storage receiver may comprise at least one side plate located between one of the planes of the dihedral reflector in the direction of the rear wall of the storage receiver parallel to the front wall, the side plate being inclined relative to the front wall.

In accordance with another embodiment, the receiver-drive may contain at least two partitions located on one side of one or more reflectors, each of which is located between the front wall and the rear wall, and each partition extends vertically to an intermediate plane located on some distance from the top wall of the receiver-drive.

Preferably, the first angle may be 90 °.

The second angle can be 45 °.

In accordance with individual specific production options, one or more dihedral reflectors can be made in the form of a curved sheet or two welded sheets.

The receiver-drive may contain two dihedral reflectors, as well as inclined side plates that extend one of the reflectors, the assembly is performed in the form of a mechanically welded whole unit.

The invention will be more clear when considering the following description of a specific embodiment, the description is given with reference to the accompanying drawings, in which:

figure 1 is a schematic side view of a weapon assembly, including a receiver-drive according to the invention, a view that allows you to show the location of the receiver-drive,

fi.2 is a schematic perspective view of the receiver-drive and its window,

figure 3 is a perspective view in partial section of a first embodiment of a storage receiver according to the invention,

4 is a perspective view, in partial section, of a second embodiment of a storage receiver according to the invention,

5 is a front view of the interior of a storage receiver in accordance with a second embodiment.

As can be seen from figure 1, the node of the weapon 1 contains a cradle 2, on which the weapon 3 is placed and which is pivotally mounted on the pins 4 attached to the machine 5. The machine 5 contains two parallel panels forming a fork, inside which the cradle 2 is placed. 5 is pivotally mounted on the support 6 to ensure the aiming of weapons 3 in azimuth (rotation around the vertical axis 7 - arrow G).

Axles 4 provide rotation of the cradle 2 and arms 3 (arrow S). The trunnion axis defines the aiming axis of the weapon by the elevation angle, which is the horizontal axis perpendicular to the vertical axis 7, as well as the axis 8 of the barrel 3a of the weapon 3. The weapon 3 is attached to the cradle 2 by means of a slide (not shown) that ensure the weapon to roll back during firing.

Such a weapon assembly is common. Patent EP 1715283, which describes such an assembly, may be considered.

Figure 1 schematically shows a dashed rectangle window 9 for ejecting cartridge cases from weapons 3. This window 9 communicates with the free space between the two panels of the machine 5.

Figure 1 also shows in dashed lines: the lower plate 10 attached to the machine 5, and the upper plate 11, plates that define the tray 12 for the extraction of cartridge cases emerging from the window 9.

The first end of the tray 12 is located near the window 9 for ejecting spent cartridges, and the second end of the tray is located near the receiver-drive 13, which is attached to the machine 5 and which allows you to store the used cartridge cartridges. The tray 12 passes into the receiver-drive at the window 14, which is created on the front wall 13A of the receiver-drive.

Figure 2 schematically shows the receiver-drive 13. In this case, the receiver-drive has the shape of a parallelepiped. On its front side 13a is a window 14, which is rectangular.

Figure 3 allows you to better consider the internal structure of the receiver-drive 13 in accordance with the first embodiment of the invention. The front wall 13a of the storage receiver is shown with a notch in order to show the storage compartment 15 defined by the walls of the storage receiver 13. Window 14 is shown by a dashed line to indicate its position.

The receiver-drive is intended for the collection and storage of cartridge cases (not shown), thrown out of the weapon 3 and which are sent to the store using the tray 12.

Cartridge sleeves enter the magazine 13 through a window 14, which is facing the tray 12 for ejecting cartridge cases.

In accordance with an essential feature of the invention, the receiver-accumulator 13 comprises at least one dihedral reflector 16, which is mounted essentially facing the window 14 and at a certain distance from it.

As can be seen from figure 3, the dihedral reflector (or dihedron) 16 contains two planes 16a, 16b, forming the first angle α between them. In this case, this angle is 90 °.

In addition, the intersection edge 17 of the planes 16a and 16b is inclined by a second angle β relative to the wall 13a with the window 14. In this case, the angle β is 45 °.

The reflector 16 is made in the form of a curved sheet. These angles α and β provide the following.

When the cartridge sleeve enters the receiver-drive 13 through the window 14, it is driven at a relatively high speed (from 5 to 10 m / s). It can bounce off the rear wall 13c of the storage receiver and return in the direction of the window 14, where it will impede the entry of the following cartridge cases. A pile of cartridge cases can also form in front of window 14.

In addition, when the window 14 is located close to the bottom 13b of the receiver-storage, there is a risk of accumulation of cartridge cases in front of the window and its blockage.

The second angle β makes it possible to deflect the path of the cartridge case striking the edge 17 of the reflector 16. In this case, the cartridge case is directed to the upper side 27 of the storage receptacle as a result of the orientation of this edge 17. Therefore, it will fall to other parts of the compartment 15 and will not clutter the space in front of the window 14.

The first angle α performs a similar function. Cartridge sleeves hitting the reflector 16 in the right plane 16a will accumulate in part D of the compartment 15 to the right of the window 14. In turn, cartridge cartridges hitting the reflector 16 in the left plane 16b will accumulate in part G of the compartment 15 to the left of the window fourteen.

3, it can be noted that the magazine contains a second dihedral reflector 18, which is mounted on top of the first reflector 16 relative to a geometric plane (not shown) passing through the vertex 19 of the reflectors and perpendicular to the front wall 13a with the window.

The relative locations of the two reflectors are such that the orientations of their planes are substantially symmetrical with respect to a given geometric plane.

Therefore, the second reflector 18 also contains two planes 18a and 18b, which form an angle γ between them. In this case, the value of the angle γ is equal to the value of the angle α (90 °). Of course, a different value is allowed for these angles.

In addition, the intersection edge 20 of the planes 18a and 18b is inclined by an angle λ relative to the wall 13a with the window 14. In this case, the value of the angle λ is equal to the value of the angle β (45 °). Of course, a different value is allowed for these angles.

According to the described embodiment, there is complete symmetry between the first dihedron 16 and the second dihedron 18 with respect to a plane perpendicular to the front wall 13a and passing through the apex 19 of the reflectors 16 and 18.

The second dihedron 18 complements the functions of the first dihedron 16. Cartridge shells striking its edge 20 are sent back in the direction of the first dihedron 16. They will hit one of the planes 16a and 16b of the dihedron to be sent back to the left G or right D sides of compartment 15 Cartridge sleeves hitting the second reflector 18 in the right plane 18a will accumulate in part D of the compartment 15 to the right of the window 14. In turn, cartridge sleeves hitting the reflector 18 in the left plane 18b will accumulate in part G of the compartment 15 on the left from the window fourteen.

This double reflector is supplemented by the first side plates 21a and 21b, which are located between the planes 16a and 16b of the first reflector 16 and the rear wall 13 with the receiver-drive.

These first side plates 21a and 21b are inclined relative to the front wall 13a with the window 14. The figure shows the angle ϕ between the rear wall 13c and the plate 21a. In the configuration shown here, the rear wall 13c is parallel to the front wall 13a of the storage receiver. The angle ϕ, therefore, also represents the inclination of the first side plate 21a relative to the front wall 13a.

The reflector is finally complemented by second side plates 22a and 22b. Each side plate 22a or 22b is positioned from the edge of one of the planes 16a or 16b of the first dihedron. These second side plates are inclined relative to the front wall 13a of the storage receiver and are placed up to the first side plate 21a or 21b located on the same side of the dihedron. Therefore, FIG. 3 shows an angle Ψ between a plane parallel to the front wall 13a and the second side plate 22a.

The purpose of the first and second side plates is to ensure that the cartridge cases entering the compartment 15 get into inclined obstacles that deflect the path of the cartridge cases and which orient them laterally to the left or right, depending on the plates being considered.

Thus, for example, the cartridge sleeve striking the second side plate 22a will be directed to the first side plate 21a, which will eject the cartridge cartridge towards the right side D of the storage receptacle at some distance from the reflector 16.

The whole structure contributes to an even distribution of cartridge cases in the magazine left or right, thereby preventing clutter along the axis in front of the window 14.

Finally, it can be noted in FIG. 3 that all plates and dihedra are mechanically welded one-piece assembly. This assembly contains rear protrusions 23a, 23b with holes that allow you to attach the device to the bottom wall 13c of the receiver-drive using screws 24.

Figures 4 and 5 show another embodiment of a storage receiver used in the invention.

This embodiment differs from the previous one only by the presence of two partitions 25a and 25b, which are located on one side of the reflector 16. These partitions are attached to the second side plates 22a or 22b and each partition is placed between the front wall 13a and the rear wall 13c. Each partition 25a, 25b also extends vertically from the side plates 22a, 22b to the intermediate plane 26, which is located at a distance d from the upper side 27 of the storage receiver 13 (see FIG. 5). The distance d in this case is such that the plane 26 is located essentially in the middle of the window 14.

As best shown in FIG. 5, the partitions 25a and 25b are inclined relative to the bottom 13b at an angle θ (in this case, the angle is 45 °).

The purpose of this tilt is to provide lateral orientation of the cartridge cases to the left G or right D after hitting the partitions.

As shown in FIG. 5, cartridge cases striking against reflectors 16, 18 and different plates and partitions are oriented along arrows F1 or F2 to pass through partitions 25a and 25b.

This design allows you to fill the compartment of the receiver-drive for storage 15 vertically up to the intermediate plane 26, without cluttering the receiver-drive cartridge in front of the window 14. It can be noted that the window 14 has a lower edge located significantly below the intermediate plane 26. The window 14 remains free for receiving cartridge sleeves using partitions 25a and 25b, which prevent clutter of the window 14 with cartridge sleeves already in the receiver-drive. Therefore, it is possible to make a compact store in which the window 14 is located very close to the bottom 13b or even on the bottom 13b itself.
