Description

The present invention relates to a rod magazine for a firearm having a slot for receiving cartridges in a stack and a shuttle for conveying the stack to a shaft end overlapped by magazine lips which retain the uppermost cartridge of the stack in the chute direction, but their movement approximately transversely to the direction of chute on the rod magazine allow addition, the shaft is equipped with extending in the direction of chess guide rails for the shoulders of the cartridges.

The Fig. 1 to 3 show such a bar magazine 1 according to the prior art in perspective ( Fig. 1 ) and in two different operating positions in section in conjunction with a repeating rifle 2 ( Fig. 2, 3rd ). The bar magazine 1 has a shaft 3 for receiving cartridges 4, 4 'in a stack. Lateral guide rails 5 in the shaft 3 serve as a stop for the shoulders of the cartridges 4, 4 'and as sliding aids in their upward movement. A bar magazine, with embossed guide rails, according to the preamble of claim 1 is known from CZ 10068 U1. A feeder 6 loaded by a magazine spring (not shown) conveys the stack to the shaft end 7.

The shaft end 7 is overlapped in its rear part of magazine lips 8, which hold the respective uppermost cartridge 4 of the stack in the chess direction (in the example shown above), while a movement of the cartridge 4 approximately transversely to the chess direction (in the example shown to the left) allow the rifle 2 to be loaded beyond the bar magazine. For this purpose, a projection 9 of the closure 10 engages between the magazine lips 8 and at the bottom of the cartridge 4 in order to introduce them by advancing the shutter 10 in the chamber 11 of the barrel 12.

As the FIGS. 2 and 3 show, runs the head or neck of the cartridge 4 on guide edges 13, 14 of the cartridge chamber 11, resulting in a slight deformation and asymmetry the cartridge can lead, which affects the shot accuracy.

It has therefore already been proposed to use rod magazines adapted to the respective weapon and the respectively used caliber of the cartridge in order to minimize the risk of deformation of the cartridge during loading. However, the known constructions are always limited to the, special weapons / magazine / caliber combinations.

The invention has the object to overcome the disadvantages of the prior art and to provide a rod magazine for a firearm, which allows an improved supply of cartridges of different caliber.

This object is achieved with a rod magazine of the aforementioned type, which is characterized according to the main claim in that the guide rails protrude beyond the shaft end and in front of the magazine lips trajectory of the uppermost cartridge.

In this way, the guide rails of the magazine shaft are utilized simultaneously for the supply of the cartridges to the chamber. The cartridges slide on the projecting ends of the guide rails and obliquely upwards and are thus aligned with the cartridge chamber, without touching the edges of the cartridge chamber. A deformation of the cartridge during the charging process is thereby avoided.

In addition, for the use of cartridges of different caliber only need the guide rails to be adapted to the appropriate caliber. As a result, rod magazines for a wide variety of calibers can be produced with one and the same magazine body and different guide rails. This simplifies the production logistics, enables higher batch sizes for the constant parts such as magazine shaft, feeder, magazine spring, magazine bottom, etc. and thus a significant cost reduction in the production of magazines for different calibers.

Preferably, the guide rails are made of metal or plastic. In the former case results in a high wear resistance, in the latter case, the risk of damage to the cartridges is further reduced.

A preferred embodiment of the invention is characterized in that the end faces of the guide rails are bevelled, wherein they project progressively stronger seen in the direction of the movement path. As a result, the friction of the cartridges when sliding on can be further reduced.

The guide rails are anchored as separate modules in the shaft, preferably modular exchangeable. As a result, the production logistics can be further simplified due to the modular combination of guide rails with magazine bodies; in the case of modular interchangeability, a caliber adjustment of the magazine by replacing the guide rails is also possible for the user.

It is particularly advantageous if at least one of the guide rails on its outside has a Beschriftüngsträger, which is visible through an opening in the shaft from the outside. This can be mounted on the guide rails a caliber designation, which is read from the outside of the magazine, so that there can be no confusion between magazines with different guide rails for different calibers.

According to a further preferred feature of the invention can be provided that the guide rails are integrally connected to each other via a common web, which simplifies the manufacture of the guide rails and their assembly in the shaft.

Preferably, the interconnected via the web guide rails are anchored by means of projections in openings or notches of the shaft, which allows a particularly simple and quick installation.

That in the 4 to 13 shown rod magazine 15 corresponds with the exception of its guide rails 16 and the details described below substantially the rod magazine 1 of Fig. 1 to 3 , where in the 4 to 13 for the same parts the same reference numerals as in the Fig. 1 to 3 be used. For a discussion of these parts of the rod magazine 15, reference is therefore made to the description of the corresponding parts of the rod magazine 1.

The guide rails 16 of the rod magazine 15 are extended beyond the shaft end 7 addition, so that they protrude in front of the magazine lips 8 trajectory of the uppermost cartridge 4. The end faces 17 of the guide rails 16 are slightly inclined, u.zw. so that they project progressively stronger in the direction of the movement path of the cartridge 4. Thus, the end surfaces 17 cause a sliding or slight upward tilting of the uppermost cartridge 4 during the charging process, as based on 10 to 12 will now be explained in more detail.

The 10 to 12 show the movement of the cartridge 4 during charging. The cartridge 4 slides over the oblique faces 17 of the guide rails 16 in the cartridge chamber 11. The end faces 17 are adapted for this purpose to the outer contour of the cartridge 4, in particular the FIGS. 7 and 8 demonstrate. Thus, the cartridge 4 is free when inserted into the cartridge chamber 11 of the edges 13, 14 of the cartridge chamber 11, as indicated at 13 'and 14'.

The guide rails 16 are preferably made of plastic and attached in any way to the inner walls of the shaft 3, for example by screwing, gluing, soldering or riveting, see the exemplary blind rivets 18 in Fig. 4 ,

The guide rails 16 can be anchored both fixed and modular interchangeable in the shaft 3.

Fig. 13 shows an alternative embodiment of the guide rails 16, which differs from that of the 4 to 12 differs in that the two guide rails 16 are integrally connected to each other via a common, preferably elastic, conforming to the inner wall of the shaft 3 web 18. Further, each guide bar 16 on its side facing the shaft to a label carrier 19, which is visible through corresponding openings 20 of the shaft 3 from the outside. On the label carrier 19, the name of the cartridge caliber can be attached, to which the guide rails 16 are adapted.

Fig. 13 further shows the magazine spring 6 'of the feeder 6 and the bottom 3' of the shaft 3 in detail.

As shown, the label carrier 19 can form projections on the outside of the guide rails 16 so that they - by taking advantage of the spring action of the web 18 - when inserting the guide rails 16 in the slot 3 in the openings 20 and thus anchor the guide rails 16 in the shaft 3 , Alternatively or additionally, further projections 21 on the guide rails 16 and corresponding notches 22 are provided in the shaft 3 for anchoring, for example - if the web 18 is not elastic and the label carrier 19 does not protrude - also allow insertion of the connected via the web 18 guide rails 16 from below into the shaft 3 before placing the bottom 3 ' ,

The invention is not limited to the illustrated embodiments, but includes all variants and modifications that fall within the scope of the appended claims.
