Technical Issue

How to load a rifle magazine with ammunition in the shortest possible time while simultaneously filling various magazines on the same device with appropriate ammunition for those rifles, so that the loading process is automated and defined by the magazine capacity? How to load magazines of type M-16 (AP-15) rifles and rifles of the AK-47(M-70) family?

Background Art

Existing rifle magazine loading devices are defined by a single caliber, a single bullet height and a single magazine shape, so that multiple devices are needed for loading different firearm magazines. Based on available documentation and its search, there is no device that can load different caliber magazines in a short time. The author has so far reported two types of magazine loading, under application P-2019/1126 for ammunition larger than 42 mm, and application P-2019/1127 for ammunition smaller than 42 mm.

Disclosure of Invention

As per the present invention, the automated universal multicaliber magazine loader for rifle magazines is designed to have in its main embodiment a bracket housing sprockets that drive two parallel chains, on which ammunition cartridges accepting all rifle bullet sizes are attached. By starting the sprockets, the ammunition cartridges move towards a plate equipped with a motion stop sensor and, at the same time, the bullet pusher, which is attached to the chain by a coupling, enters the ammunition cartridge; by starting the motor through the sensor, the chain leads the pusher to the end of the cartridge and loads the ammunition magazine via the magazine holder, which has multiple positions for different bullet sizes. By activating the sensor at the endpoint, the pusher returns to its initial position and through the chains the ammunition cartridges move by one position, i.e. the next ammunition cartridge is brought and the procedure is repeated. This system ensures that the magazine is full in one pass of the pusher.

The advantage of this design is reflected in the fact that rifle magazines are loaded quickly regardless of the ammunition caliber, within an extremely short period of time.

Detailed description of the invention

The automated universal multicaliber magazine loader for rifle magazines has its body 1 which has its sheathing 6 and a service cover 2 on the upper side, which has holes 14 for ventilation. On the front side of the body, on the sheathing 6 in the bottom part, hinges are attached, and above them there is a port 7 for a RFID reader, keys 9 for controlling the functions of the control unit 51, a lock 11 and handles 12 for transport and carrying. On the right side, in the front upper part, there is a magazine holdert 4 on the extension 3 of the cover 2, which is positioned at an appropriate angle to the horizontal plane. The entire structure is placed on device leveling brackets 5.

Under the sheathing 6, there is a frame 15, which also serves as its bracket and which by its shape can be a cube or a cuboid depending on the purpose and design; on its outer sides, at the half of its height, there is a supporting beam 62, on both sides, which is connected with the bracket 16, which by its shape can be a cube or a cuboid; on the supporting beam 62, there is a shock absorber 27 of a strainer 28, which extends to the strainer 28 which lays onto and tightens the chain 20 and chain 29, which are parallel and driven by sprockets 18, which are connected with the bracket 16 at its corners, and are also connected along horizontal axles 64, onto which ball bearings 65 are mounted between them and the sprockets 18. Inside the bracket 16, in one comer, there is a motor 24, the shaft of which extends to a pulley 25, over which there is a belt 26 that includes a pulley 19 on one sprocket 18. On parallel chains 20 and 29, at the required distance, ammunition 68 cartridges 21 are attached along the entire circumference of the chains 20 and 29.

On the front side of the frame 15, under the sheathing 6, in the upper part, there is a plate 23, in the middle of which there is a motor 53 with a shaft 31 and a pulley 32, over which there is a belt 33 which connects the pulley 34 on the sprocket 35 that drives the chain 36 over the surface of the guide 40 and over the driven sprocket 39. On the plate 23, between the pulley 32 and pulley 34, there is a strainer 37 with its housing 38. On the chain 36, next to the driven sprocket 39, near the left end of the guide 40, on the upper and bottom side, there are couplings 42 onto which a bracket 43 is tightened, and the ammunition 68 pusher 41 is attached to its upper surface; on the pusher, there is a trigger 63 of the sensor 55, while on the right side, near the end of the guide 40, there is a sensor 56. These sensors 55 and 56 have their pairs on the ammunition 68 cartridge 21, i.e. sensor 57 on its upper edge and sensor 58 on its lower edge, which determine the position of the ammunition 68 cartridge 21 in relation to the magazine holder 4; the position is fixed but may be changed depending on embodiment requirements.

The ammunition 68 cartridge 21 is designed to have a flat surface for hanging onto chains 20 and 29, using a hook 47 for one chain 20 and a security lock 48 for the other chain 29, and chains 20 and 29 have an extension 67 on their receiving elements. Above the flat part of the cartridge 21, there is a circular section that enables the reception of ammunition 68 by forming the bottom 44 towards the flat part, and vertically above it there is a cover 45, and on the opposite end it bends and creates a groove that houses a brake 50 so that the ammunition 68 pusher 41 could have uniform motion. The ammunition 68 cartridge 21 receives a 7.62 x 39 mm caliber and is universal for all rifle ammunition of similar calibers. They receive 30 bullets of a 7.63 x 39 mm caliber, i.e. 37 bullets of a 5.56 x 45 mm caliber. By pressing the keys 9, the device is put into operation to fill the magazine with ammunition 68, where the control unit 51 checks whether the signal from the sensor 55 is interrupted and, if it is interrupted, the control unit 51 sends a signal to the motor 31 driver 53 that starts the chain 36, which moves forward and carries the ammunition 68 pusher 41 in the ammunition 68 cartridge 21 to a spring 30, over which the ammunition 68 goes to the magazine holder 4. At that moment, the sensor 63 interrupts the signal on sensor 56. Then the control unit 51 sends a signal to the motor 31 driver 53 to drive it in opposite direction so that the chain 36 could return to its initial position, and to switch off the sensor 55 which stops the chain 36.

Upon filling one magazine, the control unit 51 sends a signal to the driver 52 that starts the engine 24, which through the pulley 25 and belt 26, which connects it with the pulley 19 on the sprocket 18 for chains 20 and 29, onto which ammunition 68 cartridges 21 are attached, moves until the control unit 51 receives a signal from sensor 57 and sensor 58. Upon receiving the signal, the movement is stopped and the ammunition 68 cartridge 21 is brought into the correct position against the magazine holder 4. Upon stopping the movement, the control unit 51 still receives a signal from sensors 57 and 58, and it therefore activates the motor 31 driver 53, and the cycle is repeated.

The device is automated and it fills the rifle magazine in an extremely short period of time.

The device has been manufactured and tested.
