The object of the invention is a unit for loading ammunition into box magazines of small arms, applicable for quick replenishment, with ammunition, of magazines of small arms equipped with a replaceable box magazine.
During combat operations, it is necessary to replenish the magazine with a number of cartridges after the cartridges placed therein are exhausted. In action, this is done by replacing the empty magazine with a magazine containing a set of cartridges. Empty magazines should be replenished between fights in the shortest possible time and with minimal resources. In order to shorten this time and facilitate loading, the follower should be pulled to the bottom zone of the magazine, which will facilitate the insertion of cartridges inside the magazine box.
There are known units to facilitate the loading of ammunition into the magazine.
The unit shown in patent specification EP 2857906 A1 has a pull rod which is permanently attached on one side to the undersurface of the cartridge follower and has a handle on the other side. The pull rod moves through the hole in the bottom cover of the magazine and through this movement it is possible to pull the follower towards the bottom zone of the magazine and compress the follower spring.
The unit shown in patent specification US 2012/0030987 has a pull rod which ends with a hook bend on one side and a handle on the other side. The pull rod is inserted through the hole in the bottom cover of the magazine and is hooked, with the hook located at its end, to a hole or lug in the follower. Once hooked, it is possible to pull the follower towards the bottom zone of the magazine and compress the follower spring to facilitate loading of ammunition.
The solution being the object of patent specification U.S. Pat.

The eighth embodiment is shown in a cross-section in FIG. 28. In the body 5, on the axes 23, two double-arm levers 22 are mounted, protruding beyond the upper end 3 of the body 5 and directed with the catch protrusions 4 inwards. The lower arms 24 of the lever 22 are retained by the lateral surfaces 60 of the slider 26 and are supported by the expanding spring 56. The slider 26 has the control button 7 and is supported by the spring 28 of the slider 26 which is mounted in the seat 29. In the upper zone of the body 5, between the arms of the double-arm levers 22, there is a hole 57, the lower edge 58 of which retains the surface of the bottom plate 15.
Shown in FIG. 29, the eighth embodiment has the catch protrusions 4 located above the upper end 3 of the body 5, and in the upper zone of the body 5, there is the hole 57 the lower edge 58 of which is a retention surface for the bottom plate 15. In the cut-out 27 of the body 5, there is the control button 7.
In this embodiment (FIG. 30), the bottom plate 15 has the shaped hole 16 with an outline similar to the letter “C”.
The connection between the pull-rod device 2 and the follower 11 having on its lower surface the pin 54 with the ball 55 in the eighth embodiment is shown in FIG. 31. The pin 54 with the ball 55 is connected to the follower 11. The body 5 of the pull-rod device 2 with the hole 57 moves inside the coils of the spring 14 of the follower 11.
The bottom plate 15 in a top view and its cross-section and longitudinal section relative to its main surface are shown in FIG. 32. The bottom plate 15 has stabilizing surfaces 17 vertical to its main surface, between which there is the hole 16 of the bottom plate 15.
The magazine (FIG. 33) has the pull-rod device 2 slid in, which connects to the follower 11 via the catch protrusions 4. The retention protrusions 6 block the bottom plate 15 and thereby close the compressed spring 14 of the follower 11 from below. The lower end of the pull-rod device 2 protrudes from the base cover 18 which has a closing swinging plate 20 seated on the rotation axis 21.
In order to activate the unit, the pull-rod device 2 needs to be connected to the magazine 1.
To start loading ammunition into the magazine in the first embodiment of the pull-rod device 2, (FIG. 8), the plate 20 closing the hole of the base cover is tilted downwards, then the pull-rod device 2 is slid through the cartridge hatch 10 into the housing 9 of the magazine 1 so that it passes the hole 12 of the follower 11, the hole 16 of the bottom plate 15 and the hole 19 of the base cover 18 and rests with the catch protrusions 4 on the surface of the follower 11, with the lower part of the pull-rod device 2 protruding beyond the base cover 18 of the magazine 1. The protruding part of the body 5 is then pulled to displace the follower 11 downwards while compressing the spring 14 of the follower 11. When slid through the hole 16 of the bottom plate 15 and under the action of the expanding spring 33, the retention protrusions 6 move and then are retained by the surface of the bottom plate 15 and block the spring 14 of the follower 11 from below. The coupling mechanism thus formed (FIG. 4) allows, by sliding the part of the body 5 of the pull-rod device 2 which protrudes from the housing 9 of the magazine 1, to move the compressed spring 14 of the follower 11 into the zone of the cartridge hatch 10. The process of loading ammunition into the magazine 1 takes place. Successive cartridges, slidable into the magazine 1, push the coupling mechanism (FIG. 4) downwards. When the magazine is fully loaded, the follower 11 and the compressed spring 14 of the follower 11 will be blocked from above by the cartridges contained in the magazine 1. Once the loading process is complete, the control button 7 is slid downwards, causing the slider 26 to move downwards and unblock the lower arms of the double-arm catch levers 24 which then perform a rotation about their own axes 23 and the catch protrusions 4 move into the body 5 of the pull-rod device 2. Once these operations are complete, the pull-rod device 2 is slid out of the housing 9 and the control button 7 is released, which causes the slider 26, under the action of the spring 28 of the slider 26, to move upwards and again block the lower arms of the double-arm catch levers 24 which are again located in the shaped retaining recess 25 of its upper edge, which makes the pull-rod device 2 ready to cooperate with the magazine 1 again. Loading in the second and third embodiments is performed by carrying out the steps as in the first embodiment.
Loading the magazine with the solution shown in the fourth embodiment (FIG. 14): the plate 20 closing the hole 19 of the base cover 18 is tilted downwards. In turn, the retention slider button 39 is slid downwards. The pull-rod device 2 is then slid into the housing 9 through the cartridge hatch 10 to pull its lower part to the stop. Next, the retention slider button 39 is slid upwards, which causes the retention discs 43 to be slid under the surface of the bottom plate 15 and the latter to be blocked, after which the coupling mechanism is slid into the zone of the cartridge hatch 10 and the loading of ammunition into the magazine begins. Once ammunition is loaded, the control button 7 is slid downwards and the body 5 of the pull-rod device 2 is slid, which will cause the catch discs 42 to move into the body 5 of the pull-rod device 2, thus allowing the pull-rod device 2 to be slid out of the housing 9 of the magazine 1. When loading the magazine 1 with the solution according to the fifth embodiment (FIG. 16), the pull-rod device 2 is slid in through the cartridge hatch 10 so that the catch surfaces of the steel balls 46 rest on the surfaces of the follower 11, and then the body 5 is pulled down to the stop. In turn, the body 5 of the pull-rod device 2 is rotated around its longitudinal axis so that the external thread 47 of the body 5 of the pull-rod device 2 is connected to the bottom plate hole thread 51 of the magazine 1. The coupling mechanism formed by these actions moves to the vicinity of the cartridge hatch 10. The magazine 1 is prepared to load cartridges. Once the cartridges are loaded, the rotary handle 50 unblocks the steel balls 46 to move them into the body 5, after which the body 5 of the pull-rod device 2 is disconnected from the bottom plate 15 by unscrewing the body 5 of the pull-rod device 2 from the thread 51 of the bottom plate hole 16 and the pull-rod device 2 is removed from the housing 9 of the magazine 1.
To load the magazine 1 with the pull-rod device 2 in the sixth embodiment (FIG. 20), the pull-rod device 2 is slid into the housing 9 of the magazine 1 through the shaped hole 16 of the bottom plate 15 and slid towards the follower 11. Then, the control button 7 is slid and the upper end 3 of the body 5 is placed in the hole of the follower 11 and the control button 7 is released so that the retention protrusions 4 catch on the surfaces of the follower 11. Thereafter, the body 5 of the pull-rod device 2 is moved so that the alternating arms 52 of the sleeve 53 come into contact with the surface of the bottom plate 15, after which the rotary sleeve 53 is rotated so that the arms 52 move through the hole of the bottom plate 15 and the sleeve 53 is rotated again to rest the arms of the sleeve 52 on the surface of the bottom plate 15 and move the coupling mechanism to the zone of the cartridge hatch 10, and start the loading of ammunition. Once the magazine is loaded, the control button 7 is moved downwards and the pull-rod device 2 is removed from the housing 9 of the magazine 1.
In the seventh embodiment of the pull-rod device 2 (FIG. 24), in order to load the magazine 1, the plate 20 closing the hole 19 of the base cover 18 is tilted, and through this hole and the hole 16 of the bottom plate 15, the pull-rod device 2 is slid in, moving the upper end 3 of the body 5 to the vicinity of the ball 55 of the follower 11. When the control button 7, and together with it the slider 26, is moved, the lower arms 24 of the double-arm catch levers 22 are unblocked. The catch protrusions 4 catch on the ball 55 of the follower 11, after which the control button 7 is released, which again blocks the double-arm catch levers 22. In turn, the body 5 of the pull-rod device 2 is moved downwards so that the retaining surfaces 61 of the body 5 of the pull-rod device 2 slide under the surface of the bottom plate 15, and the coupling mechanism formed by these actions (FIG. 4) slides into the zone of the cartridge hatch 10. The magazine 1 is prepared to load ammunition. Once the loading is complete, the control button 7 is slid to unblock the catch protrusions 4, previously latched against the ball 55 of the follower 11, and the pull-rod device 2 is removed from the housing 9 of the magazine 1.
In the eighth embodiment (FIG. 28), in order to load the magazine 1, the actions as in the seventh embodiment are carried out, with the lower surface of the bottom plate 15 being blocked by the lower edge 58 of the retention hole 57 of the body 5 of the pull-rod device 2.
