Not applicable.
The invention relates to cartridge ramps enabling the cartridge in the magazine to be loaded to the muzzle in rifles with vertical magazine (vertical cartridge holder).
The invention relates in particular to the cartridge ramps formed with angled/bevelled surfaces integrated to one another at points where three elements intersect in the inner sides of the magazine, upper frame and barrel bearing, without using an additional mechanical configuration on the magazine or lower frame.
Rifles with vertical magazines consist of five main structures, namely the butt, lower frame, upper frame, magazine and barrel. In the magazine, there are various number of cartridges depending on its capacity. The cartridges in the magazine are pushed to the barrel bearing one by one, by each shot. On the magazine or lower frame, there are mechanical elements called cartridge ramps enabling the cartridges to be loaded to the barrel bearing one by one.
In the state of the art, the cartridge ramp in shotguns with vertical magazines is fixed/integral to the lower frame or is done so by fixing it later with the help of a pin or screw.
In the state of the art, the cartridge ramp in shotguns with vertical magazines is made by fixing it later with the help of a pin or screw in a folding manner.
The cartridge ramp systems described above are used in shotguns without riffling and in unrifled shotguns with vertical magazines, a ramp connected to the lower frame is necessarily needed. The cartridge (ammunition) in the cartridge is dragged forward towards the cartridge ramp with the help of a bolt and the tip of the cartridge arriving to the ramp moves with a friction parallel to the angle of the ramp and sets in the breech and the cartridge becomes ready to shoot. In unrifled shotguns, if there is no cartridge ramp, the cartridge does not arrive to the breech and the rifle will not work.
When the utility model registration no TR2014 11006 titled “Spring Cartridge Ramp for Rifles with Magazine” found in the literature search in the state of the art is reviewed, it is understood that it describes a cartridge ramp connected on the magazine and opens and closes by means of a spring.
When the patent registration no U.S. Pat. No. 10,941,995B2 titled “AR Type Automatic Rifle with Separable/Vertical Magazine” found in the literature search in the state of the art, it is understood that it is related to loading the cartridge to the barrel bearing by opening and closing of the two tabs driven by the spring towards the two sides of the barrel in order to load the cartridges to the barrel bearing. The biggest disadvantage of this system that problems occur while loading cartridges with certain calibres to the barrel bearing since each cartridge may have different weight and size depending on its calibre.
Conclusively, the existence of the above problems and the insufficiency of the existing solutions made it necessary to make an improvement in the technical field related to the cartridge ramps used in rifles with vertical magazines.
The present invention relates to a cartridge ramp meeting the abovementioned requirements, eliminating all disadvantages and bringing some additional advantages.
The main aim of the invention is to provide a cartridge ramp formed with angled/bevelled surfaces integrated to one another at points where three elements intersect in the inner sides of the magazine, upper frame and barrel bearing, without using an additional mechanical configuration on the magazine or lower frame.
In an embodiment aimed with the cartridge ramp described above, it is aimed to enable the rifles to shoot the cartridges the unrifled shotguns shoot without interfering with the lower frame of the rifle, by adapting the cartridge ramp to be formed in the magazine+upper frame+barrel bearing (upper kit) we designed to the automatic and semi-automatic rifles shooting ammunitions of 7.62 diameters. By this way, a rifle shooting 7.62 ammunition was enabled to shoot 12 calibre shotgun shell. Said rifles can be all rifles shooting 7.62 ammunition like AR-10, AR-15, etc.
Another aim of the invention is to enable, with the designed cartridge ramp system, the production of the standard unrifled shotguns with vertical magazine without adding the cartridge ramp on the lower frame or magazine as an additional part. The aim here is to prevent the rifle from jamming (seizing etc.) due to problems to occur in the cartridge ramp working mechanically and to minimize the costs by this way.
The structural and characteristic properties and all advantages of the invention will be more clearly understood with the figures given below and the detailed description written with reference to these figures and therefore, the assessment should also be made by taking these figures and the detailed description into account.
In order to for the embodiment of the present invention and its advantages with additional elements to be understood in the best way, it should be evaluated together with the figures described below.

10. Lower frame
20. Upper frame
35.1. Support ramp
The drawings are not necessarily scaled and the detailed that are not essential to understand the present invention may have been omitted. Apart from this, elements that are at least substantially identical or have at least substantially identical functions are shown with the same reference numbers.
In this detailed description, the preferred embodiments of the cartridge ramp (50) designed to be used in rifles-shotguns with vertical magazine (A) are described only for the subject to be understood better, having no limiting effect.
The rifle with vertical magazine (A) which is the subject of the invention comprises a lower frame (10) on which the trigger pull is located, upper frame (20) in which the barrel bearing (35) and the mechanism enabling the cartridge to be shot with the burst is located, the barrel (30) connected to the barrel bearing (35) inside of which the fired cartridge is directed to the target, and the magazine (40) located rectangular to the rifle, in which various ammunition ready to be shot are stored (
In the rifle with vertical magazine (A) which is the subject of the invention, an additional external structure connected to the lower frame (10) and the magazine (40) later, enabling the loading of the cartridge from the magazine (40) to the barrel bearing (35) in each shot, is not used. A cartridge ramp (50), formed on the inner sides of the upper frame (20), barrel bearing (35) and the magazine (40) elements with angled/bevelled surfaces integrated to one another at points where the three elements intersect, the lower frame (10) remaining the same, is designed to provide the seamless loading of the cartridges of different calibres from the magazine (40) to the barrel bearing (35).
The designed cartridge ramp (50) begins with exit ramp (40.1) formed in an angled/bevelled manner at the part where the cartridge exits the magazine (40), the magazine (40) being connected to the upper frame (20). Then is followed by the feeding ramp (20.1), adjacent to the exit ramp (40.1), formed in an angled/bevelled manner at the part where the magazine (40) is connected at the lower part of the upper frame (20) over which the cartridge will pass. As the final stage, it ends with support ramp (35.1) (
With the cartridge ramp (50) system described, it is ensured that the rifles shoot the cartridges the unrifled shotguns shoot without interfering with the lower frame (10) of the rifle, by adapting the cartridge ramp (50) to be formed in the magazine (40)+upper frame (20)+barrel bearing (35) triplet (upper kit) we designed to the automatic and semi-automatic rifles with vertical magazine (A) shooting ammunitions of 7.62 diameters. Said rifles can be all rifles shooting 7.62 ammunition like AR-10, AR-15, etc.
The scope of protection of this application has been determined in the claims section and cannot be limited to what is explained above definitely for exemplary purposes. It is clear that a person skilled in the art can demonstrate the innovation set forth in the invention by using similar embodiments and/or can apply this embodiment to other similar purposes used in the related art. Therefore, it is obvious that such constructions will lack the criteria of innovation and especially going beyond the state of the art.
