The present disclosure relates generally to firearms, and more specifically to improved magazines for firearms.
In the case of most semi-automatic and automatic firearms, the cartridge (ammunition) feed can be achieved for example by means of a magazine. Conventional forms of magazine for semi- and fully-automatic firearms are for example the box magazine, stick magazine and curved magazine.
A magazine generally comprises an elongated body having a largely rectangular cross section. The upper end comprises magazine lips and an opening in order to be able to transport the top cartridge, in each case, into the chamber of a firearm. The lower end comprises a magazine butt that is connected to the magazine body. Between the upper and lower end, viewed from the top, the magazine body contains a feeder that is connected to a magazine spring, the magazine spring being connected directly, or by means of a base plate, to the magazine butt.
The spring force of the spring pushes the feeder upwards and, when the magazine is empty, as far as the magazine lips. For the purpose of filling, cartridges are pushed from above, through the opening and into the magazine, in such a way that the feeder is pushed slightly downwards, counter to the spring force, in each case. The spring is pre-tensioned more strongly with each cartridge that is additionally inserted into the magazine, and therefore insertion of the next cartridge, in each case, into the magazine requires an ever stronger downward force. Filling of the magazine is furthermore impeded by the round cartridge cases possibly sliding off one another, and the design that tapers towards the cartridge tip and, in the case of rimfire cartridges, the larger diameter of the cartridge base compared to the sleeve, also make the process more difficult. Conventional filling of a magazine with cartridges is therefore accordingly difficult, in particular the more a magazine is already filled. The filling accordingly requires time, dexterity and force.
Accordingly, loading aids have long been known in the prior art, which facilitate filling of magazines with cartridges.
U.S. Pat. No. 9,846,004 B2 and US 2018/231 339 A1, for example, each disclose a magazine comprising a slit in one of the side walls, and a feeder comprising an opening, on which a tool can be set against a side of the magazine, in order to push the feeder downwards. Setting the tool on one side is disadvantageous in that canting and jamming of the feeder may occur when it is being pushed down. A further disadvantage is that the loading aid is present only in the combination: “magazine with tool,” so a separate tool is required.
US 2019/219 352 A1 discloses a magazine comprising a lateral slit and a knob that is attached to one side of the feeder and protrudes beyond the magazine body, at which knob the feeder can be pushed downwards. Attaching the knob on one side means that canting and jamming of the feeder is possible. The non-flush finish of the knob with the magazine body also has a disadvantageous effect. A loading aid of this kind that protrudes beyond the magazine body and is rigidly connected to the feeder is also disclosed in US 2016/003 568 A1. A loading aid that protrudes beyond the magazine body cannot be easily introduced into the magazine well of a firearm; particular designs are necessary which for example require more space and material, and/or result in heavier magazines.
GB 110577 A discloses a magazine comprising a slit on both sides, and a loading aid which is attached in the magazine by means of a thread and can be operated from both sides. The necessarily laborious manufacture of the thread: as well as the lack of loss proofing, have a disadvantageous effect.
For the jurisdictions in which this is possible, the content of these documents is incorporated, by reference, into the content of the disclosure of this application.
The object of the present disclosure is that of preventing the mentioned disadvantages of the prior art and of providing a magazine with an easily collapsible loading aid, which exhibits a reduced risk of loss. A further object for embodiments of the disclosure is that of providing an optimized, reliable magazine, and making the loading state of the magazine both visually and/or physically identifiable without having to manipulate the firearm.
The present disclosure is directed to a magazine for a firearm, including a magazine body having two sides, including at least one slit in each of the two sides; a feeder, the feeder defining a slide receptacle extending through the feeder; and a loading aid. The loading aid includes a first and a second slide that are configured to be reversibly coupled to each other inside the slide receptacle by a latch, so that a first side face of the first slide and a second side face of the second slide are each disposed outside the magazine body; and the feeder defines at least one hole in a direction of the slide receptacle to permit an uncoupling of the latch.
The magazines of the present disclosure will be described in greater detail in the following, with reference to the drawings, in which:
The magazines according to the present disclosure include modifications of magazines that are known per se, for example for pistols and other firearms. The improvements can be achieved by virtue of the magazines including a collapsible loading aid which can be installed in a simple manner, without tools, in a manner that is loss-proof, and that can be removed from the magazine easily and requiring only a simple tool.
Throughout the present disclosure and the appended claims, “front” or “forwards” refers to the direction towards the muzzle of the barrel of the firearm, “rear(wards)” refers to the direction towards the stock, “bottom” or “downwards” refers to the direction from the magazine lips towards the magazine butt, and “top” or “upwards” refers to the direction from the magazine butt towards the magazine lips.
Similarly, as used herein “lateral surfaces” refer both to the left-hand and right-hand surfaces between the front and rear end of the firearm, as viewed in the muzzle direction. The designations “magazine,” “feeder,” “magazine butt,” “magazine plate,” etc. have the conventional meaning that a person skilled in the art attributes to them in the prior art. Surfaces that are “in parallel” with an axis form cylindrical lateral surfaces, “recesses” relate to the surrounding regions of the object considered, etc.
The magazines of the present disclosure include a loading aid with a decreased risk of loss but that is nonetheless easily collapsible. Over the entire vertically displaceable region, the loading aid is designed so as to be set back with respect to, or at most flush with, the contour of the magazine body. As a result, the magazine can be used in a firearm in a very trouble-free manner, and in a manner preventing jamming, even when said magazine has an in-built loading aid. Furthermore, the loading aid can be brought into a collapse position, and subsequently collapsed, merely using a simple tool, e.g. a collapse pin, by means of light pressure on at least one latch-forming projection, through the collapse opening/the hole.
It has been found to be particularly advantageous for the loading aid to comprise two slides that can be inserted into one another. The sides are designed so as to be complementary in shape to one another, comprising a bolt holder and a slide bolt, in the region thereof that can be inserted into one another. As a result, the loading aid can be easily installed in the assembled magazine; all that is required is to insert the first and second slide into the slide receptacle, and to push the slides together, e.g. using fingers.
An aperture that proceeds from the bolt receptacle and, in the installation state, is connected to the hole, and at which aperture a stop face or support surface is formed, is particularly expedient. The stop face is preferably closer to the second grip than the support surface. An extension comprising a projection that protrudes in the radial direction and forms a latch and an end face is formed on the first slide, the latch being closer to the first grip than the end surface. The projection is designed so as to be complementary in shape to the aperture, and preferably faces downwards.
The advantage of this embodiment is that the latch of the first slide interacts with the support surface of the second slide, and prevents a relative movement of the first slide away from the second slide, in the axial direction of the second slide bolt. Furthermore, the end face of the first slide interacts with the stop face of the second slide, and prevents the relative movement between the first slide and the second slide, in the axial direction of the second slide bolt. In the installation state, the two slides of the loading aid are rigidly interconnected.
In other words, the extension can be resiliently deflected relative to the first slide bolt, in the direction of a collapse position. In the collapse position, the extension comprising the latch-forming projection is free from the support surface, allowing for the two slides to slide axially apart from one another.
It may furthermore be possible for the feeder to comprise a collapse opening that is designed as a hole and which makes the aperture, and thus the projection, accessible. A force effect on the projection, which effect is substantially normal to the axis of the second slide bolt, releases the latch from the support surface, and thus defines a collapse position.
A hole of this kind is advantageous in that light pressure can be exerted on the projection by means of a simple tool, such as a collapse pin, as a result of which the loading aid can be collapsed without problem, even on an assembled magazine. After pressure has been exerted on the projection, the loading aid is collapsed simply by gently pulling apart the two grips.
An advantageous embodiment is one according to which, on the first and/or second grip first and/or second lateral surfaces are formed so as to be complementary in shape to a groove side of the groove, and a first and/or second inner surface is formed so as to be complementary in shape to the groove base of the groove.
In this way, when the feeder is moved vertically in the slit, the first and second lateral surfaces can interact with the groove side, or first and second inner surfaces can interact with the groove base, and be guided thereby. This guidance stabilizes the orientation of the feeder in the x, y and z axis (x-axis: front/back; y-axis: left/right, and z-axis: vertical or in the direction of the magazine axis, and thus substantially in parallel with the slit), and thus acts against canting.
Particularly expediently, it may be possible for the slide receptacle to be designed so as to be complementary in shape to the first slide bolt. The complementary design promotes a secure seat of the loading aid in the slide receptacle.
A slide bolt that is designed so as to be circular in cross section is advantageous, since an embodiment of this kind is advantageous in terms of manufacture, and possible forces that may arise in the material can be diverted particularly successfully.
A further advantageous embodiment involves an elongated shape, similar to a slot, comprising two parallel longitudinal surfaces, in the cross section of the second slide bolt and the slide receptacle. Said parallel longitudinal surfaces interact with the slit side, and the feeder is thus additionally guided, during vertical movement, and the anti-canting effect is increased.
In a further advantageous embodiment, the cross section of the second slide bolt and the slide receptacle comprises an end face. Said end face makes it unlikely that the loading aid is installed with the incorrect orientation, i.e. in the orientation having the projection facing away from the hole.
A further advantageous embodiment comprises an asymmetry element somewhere on the cross section of the second slide bolt and the slide receptacle, the shape of which element also just allows precisely one orientation for installing the loading aid in the magazine. Installation in the incorrect orientation, i.e. having an indicator facing away from the loading state display, can be prevented.
It is furthermore possible for a first indicator to be arranged on the first slide and/or for a second indicator to be arranged on the second slide, and for a loading state display to be arranged on the magazine body, preferably on the side thereof. The indicator and/or loading state display can be optically, in particularly luminescent, and/or haptic perceptible, e.g. formed by means of a notch, depression and/or elevation.
An embodiment of this kind is advantageous in that the user can immediately and easily visually identify the loading state of the magazine. In the case of a luminescent design, optical identification is possible even in darkness. The haptic embodiment allows for identification of the loading state by feel, without visual contact.
It may furthermore be expedient for the grip surface of the first and/or second grip to be designed so as to be anti-slip and to comprise at least one anti-slip notch.
This is advantageous in that the feeder can be pushed slightly downwards, counter to the spring force, for the purpose of filling the magazine, and it is possible for the feeder to be shifted downwards in a reliable and trouble-free manner, and thus for the magazine to be filled easily, even in the case of low-friction, slippery conditions, e.g. hot, humid weather and sweat formation, or possible impurities on the hands and/or on the loading aid by lubricating or oily substances.
It is clear to a person skilled in the art that symmetrical embodiments are possible without difficulty, and can be read in passively along with both the description of the figures and the claims. In particular, embodiments of the magazine according to the present disclosure comprising at least two latches formed in the loading aid are possible. The feeder comprises a corresponding number of holes in order to make the latches accessible and to allow for the collapse process. For reasons of simplicity of representation and brevity of description, primarily an embodiment comprising just one latch will be described in the following description.
On the sides 112 thereof, the magazine body 11 comprises an elongated slit 120, oriented substantially in the vertical direction, in each case, which slit ends at a distance both from the butt 14 and from the lips 13, such that the sides 113 of the magazine body 11 are continuous in each case, at the top and bottom.
In the preferred embodiment shown, the magazine body 11 comprises, on the sides 112 thereof along the slit 120, a groove 170 comprising a groove base 171 and groove side 172, the groove base 171 being designed so as to be substantially in parallel with, and the groove side 172 being designed so as to be substantially normal to, the side 112.
The loading aid consists of a first slide 30 and a second slide 40 and, in the installed state, is arranged in a slide receptacle 21 of the feeder 20. In the installed state, the assembled loading aid penetrates the magazine body 11 in the region of the slit 120; and is recessed with respect to, or flushes with, the sides 112. During the loading process of the magazine 10, the loading aid is repositioned in the slit 120, counter to the force of the spring 16, filling of the magazine 10 with cartridges being facilitated by the feeder 20 that is pushed down by the loading aid.
As is particularly clearly visible in
In order to collapse the loading aid, pressure is exerted on the projection 37 from below, and presses said projection out of the aperture 45, by means of resilient deformation. In this case, the support surface 46 releases the latch 36, and the first slide 30 can be moved out of the second slide 40, in the axial direction. In addition to a suitable material selection, the particular design of the bending groove 35 (in the manner of a taper of the cross-sectional surface area) assists this procedure, since this allows for and/or facilitates spring deflection of the extension 34 upwards. The collapse position is thus achieved in that a force that is substantially normal to the axis of the second slide bolt 41 acting on the projection 37, through the hole 24, releases the latch 36 from the support surface 46.
As shown in
In a preferred embodiment, the first and second grip 330 and 430 are positioned completely in the groove 170 of the slit 120, and end flush with the sides 112 of the magazine body 11. A cross section of the first and second grip 320 and 420 that tapers inwards, towards the top, and is thus slightly triangular, can be seen particularly clearly in
In a preferred embodiment, and as shown in
Interaction of lateral faces 322, 422 with groove sides 172, or of inner faces 323, 423 with groove bases 171, makes it possible to prevent canting in the x, y and z direction of the feeder, during movement in the vertical direction. This anti-canting effect facilitates the loading process and also promotes an optimized cartridge supply when in use, and impedes possible jamming.
The width/the diameter of the second slide bolt 41 substantially corresponds to the width B1 of the slit 120 (
The loading state display 19 can also be designed so as to be luminescent, i.e. easy to identify even in the dark. Loading state displays having an individual optical or haptic design are possible, or a combination of a plurality of optical and/or haptic designs.
It should also be specifically noted that the specified coordinate system does not have to be orthogonal, and can also rotate relative to the magazine butt, and/or the angle of the z-axis with respect to the plane spanned by xy can change, with the position considered in each case, in particular in the case of curved magazines, since said coordinate system is used only to explain the situation present in each case.
The magazine 10 according to the present disclosure can, for example, be produced largely from plastics material or metal. Furthermore, different material combinations of plastics material, metal, ceramic or composite materials are possible.
The magazine according to the present disclosure can be produced for example by means of machining processes, such as milling, turning or grinding, and likewise the magazine according to the present disclosure can be produced by means of shaping processes, such as injection molding, extrusion or MIM, or alternatively also by means of additive manufacturing processes such as 3D printing, or a combination of these or similar methods.
