Description

The invention relates primarily to a mechanical device capable of holding in the working position an automatic gun loader of medium capacity and to guarantee the same position to another loader (or store) of larger capacity, therefore heavier. This retention mechanism is advantageously designed so that one of the control button can be operated indistinctly by a right-handed or left-handed user.

[0002] We have examples of firearms, mainly automatic ones, which have several means, usually two, for holding feeders or loaders. These technical means have hardly been used since the end of the First World War except for some applications concerning collective weapons (machine guns etc.). Although the reasons for this abandonment are numerous, we will retain only the two main ones; The first is the consequence of the progressive freezing of the techniques of the feeding devices (charger) and their modes of restraint as the evolution of the weapons and their ammunition. This technical "freeze" will accelerate the categorization of weapons, including war, from the end of the First World War and will define for a long time the general architecture of these then preventing the use of another charger than the one for which it was designed. The industrial and commercial interest being not foreign to this "categorization", the specialization of a feeder or charger, by its shape and its mode of restraint, invariably restricts any attempt to use an exogenous component can certainly come from another manufacturer of similar equipment, in a few words, a competitor. The second reason for gun designers and manufacturers of all types to "specify" and specialize power devices, or chargers, for a specific model of weapon, was inspired by a political will, often confused, major states (relayed by their technical services) industrial nations, which favored the principle of ammunition "national or imperial" supposed to prohibit the future enemy to use the same ammunition in case of war (you never know!). This policy will last until the so-called "cold war" period, which upset this situation. After the chaos of the Second World War, there would be no more than the ammunition of two superpowers. This new situation would allow a greater rationalization of the calibres of the munitions of war which will define until today a "standard" for each of the two blocks. The laborious standardization of the ammunition would also imply that of the vector of supply of a light automatic weapon called "charger" or "store". New weapons have emerged in this last decade, which upset the old concepts, both mechanical operations and manufacturing methods, the machine gun KRISS GAMMA / KRISS company is a remarkable example. This weapon of a very particular design was designed with the stated purpose of using a magazine system now a great global standard. This trend already very common in the field of the assault rifle, tends to prevail for all categories of weapons including the submachine guns. This standardization naturally leads to another industrial concept, "compatibility". The industrial and commercial logic of our world, which is also that of arms, invariably leads to this standardization of things; objects, various and varied components, recognition of this state of affairs, allows to grasp the interest of the device, object of the invention, which abounds in this direction.

The object of the invention is, at first, to allow an automatic weapon of the category of a submachine gun and mainly the type of weapon preferably cited, the use of a conventional charger (or store) of automatic pistol whose capacity corresponds to modern standards (from 13 to 15 shots on average) but also loaders of much greater capacity, (from 25 to more than 32 shots) more adapted to the very nature of a weapon of this category. In a second step, to promote greater ease of manipulation for the user, implying "de facto" ability to actuate a control button, by any finger of his right or left hand, guaranteed a perfect ambidexterity, enabling the release, the extraction, the expulsion of a charger in a minimum of time thanks to a better ergonomics facilitating this action and this whatever the type of compatible charger used. In a third step, knowing that the personnel of groups and forces of special interventions are generally endowed, in addition to their offensive weapons, of an automatic pistol, the device object of the invention, allows these personnel who would be in critical combat situation (and having exhausted their ammunition packaged in high-capacity magazines (at least 25 rounds), to use the magazine (s) of their pistols.This advantage allows these personnel to have a final firepower Automatically with a weapon more precise and efficient than an automatic pistol, this advantage, that the invention offers, may be essential in certain situations.

The mechanism, characterizing the invention, combines two known systems for retaining chargers but advantageously associated and actuated by a single control button. This mechanism provides an original and effective solution for the indiscriminate use of a conventional automatic pistol loader and / or loader of greater capacity while ensuring a perfect ambidextrie of the release control of these chargers by a single , classic and simple, press a finger on a command or button. Such a device advantageously characterizing the invention, allows a weapon, which would be equipped with it, to use either an automatic pistol charger, of a certain type, or a charger of greater capacity more suited to the category of the weapon mentioned in this document. Another advantage of the invention, the long loader or large capacity, described in this document may be, according to certain requirements, provided with an upper stopper, identical to the model of short loader, allowing conversely its use in a gun automatic capable of receiving the same charger or magazine. The capacity of an automatic pistol loader rarely exceeds 15 shots depending on the caliber, although a certain mode tends to excessively increase the capacity of the latter to the detriment of the quality of its behavior and the constraints imposed by a surplus of weight to the charger lock. A submachine gun can not be satisfied with the use of only such small magazines, knowing that a magazine gun magazine is usually 25 to 30 rounds. This is an average, but proven techniques can significantly exceed this capacity. Although the use of more and more synthetic materials for the production of high capacity loaders has significantly reduced the weight, it is still too important and generates too much dynamic constraints, during a shooting and especially in automatic shooting, for a simple automatic pistol lock. The use of two loader locks, advantageously characterizing the invention, able to operate simultaneously and jointly, allows the weapon which is equipped with it to use either a conventional pistol loader, ie of a small capacity, or a other large capacity, more generally called in this document "long charger". The weight and the constraints generated by the latter are easily supported by a perfectly sized latch for this task.

Operation.

The mechanical device, object of the invention described further, operates in the following sequence, considering that is already introduced a magazine (magazine) in the well of the weapon charger and that it is empty or not . The user decides to replace one charger with another according to his convenience or necessity. It does this by the action of one of the fingers of one or other of its hands, a thrust on one or the other end (D) (right) and / or (G) (left) of the control button (2) fig. 1, fig. 2, fig. 3, fig. 4 and fig. 7. It slides in the housing (35) of the magazine well body (1), fig. 12, and via one of the slopes (21), (21), whose angle will be at least equal to 45 ° but preferably 60 °, provided on the inner faces of the recess (20) , fig. 7 of said control button (2), fig. 7. The sliding of the control knob (2), simultaneously and jointly constrained, the upper latch (7) lock (7), fig. 1, fig. 2, fig. 3, fig. 4and fig. 6, sliding in the groove (34) of the loader well body (1), fig. 12, as well as the lower lock (3), fig. 8, positioned in the housing (36) of the loader well body (1), fig. 12, by its axis (8), Fig. 3, Fig. 4 also guiding it in rotation through its bore (8), fig. 8, fig. 8, and itself retained in the body of the loader well (1) by the bore (37), fig. 12. This action always simultaneously and jointly causing the displacement of the upper lock (4) fig. 5, in the direction of the arrow (F), fig. 4, perpendicular to the axis of force of the pusher (7) fig. 6, shown by the arrow (C), fig. 4. The upper latch (4), fig. 5, supporting by construction, an extension (12), fig. 5, receiving the end of the guide rod (6) of its return spring (10) and whose head (32) of this guide rod (6) bears against the inner face of its housing (33). the recess (1) of the magazine well body (1), fig. 1, fig. 2, fig. 12, constrained by this one, fig. 3, fig. 5, (this embodiment is indicative) is, at this moment, engaged in the recess (26) formed in the wall of the charger (5), (5), fig. 9, fig. 11, and whose stop (15), fig. 5, engaged under the upper face (27) of the recess (26) of the loader (5), (5), fig. 9, fig. 11, is separated by the pusher (7), fig. 6, whose slope (16), fig. 6 comes into contact with the slope (14), fig. 5ménagé on one of the surfaces of the recess (13) made in the upper latch (4) and in contact with the oblique plane (16) of the pusher (7), fig. 6. This same action on the charger lock button (2) fig. 7, constrains the lower lock, (3) fig. 8, fig. 8 to pivot on its axis (8) leads by its bore (8) fig. 3, fig. 4, fig. 8, fig. 8, in the direction of the arrow (E), fig. 4, simultaneously at a defined angle capable of releasing its face (24), FIG. 8 of the face (28) of the lug (27) of a suitable long loader, (5), (5), fig. 10, fig. 11. Any action on any end (D) and / or (G) of the control knob (2) fig. 4, forces the upper latch (4) to release, in this case, the magazine (or magazine) (5), (5), fig. 9, fig. 11. This is ejected from the housing (1) of the magazine well (1), fig. 2, fig. 12, manually by the user, by the effect of gravity or the action of its lifting plate constrained by its spring, against the ventral side of the breech or what serves and / or the stop of a any charger end blocking device. At the same time, in the case where a magazine (or magazine) "long" (5), fig. 10, would have been introduced according to the same procedure as the conventional or short loader (5), fig. 9, the lower latch (3), moved by the control knob (2), fig. 7, fig. 7, following the work obtained by the sliding of the slopes (19) and (19), constructed by producing the recess (18), fig. 7, the same control button (2), fig. 7, fig. 7, and through the surfaces (23) and (23), formed on each side of the tail (22) of lower latch (3), fig. 8, disengage its bearing face (24), fig. 8, the other support face (28) of the extrusion or lug (27) of the magazine (magazine) (5), (5), fig. 10, fig. 11. The long magazine (5), (5), fig. 10, fig. 11, is ejected from the housing (1) of the loader well (1), fig. 2, fig. 12, according to the same effects specified further. Any of the ejected magazines will be replaced by a simple procedure common to all automatic weapons and taking place, as in our case and that of the invention, as follows; A "short" charger (5), fig. 9, is physically introduced into the housing (1) of the loader well (1) fig. 1, fig. 2, fig. 9, fig. 12, until finding its ideal locking position allowing the engagement of the stop (15) of the upper lock (4). Fig. 5, under the upper face (27) of the recess (26) in the wall of the loader body (5), FIG. 9. The classic form of a modern loader and in particular that which is shown in the various sketches attached to this document, naturally facilitates the engagement of the stop (15) of the upper lock (4), fig. 3, fig. 5, by a "wedge" effect caused by the angle (30) materialized by the neck of the magazine (or magazine) (5), fig. 3, fig. 9, fig. 10, fig. 11.

In another case, a long magazine (5), fig. 10, is introduced in the same way as that described above for the loader (5), fig. 9, in this case the lower lock (3), fig. 8, fig. 8 is pushed by the nose (31) of said loader (5), fig. 10, coming into contact with the slope (25) of the lower lock (3), FIG. 8 which forces it to pivot naturally on its axis (8). This pivoting constrains its return spring (9), fig. 3, positioned in the groove (9), fig. 8, and one of the branches bears against the face (40) of the recess (1) of the magazine well (1), FIG. 1, fig. 2, fig. 12, receiving indistinctly any of the chargers described in this document. According to another embodiment, the long magazine (5), FIG. 11, can have the same type of retaining catch of the short loader (5), fig. 9. This long magazine (5), fig. 11, then having two retainers which promote a better holding thereof in the housing (1) of the loader well (1), fig. 1, fig. 2, fig. 12 considering its weight which, depending on its capacity, can be more than double that of the short magazine (5), fig. 9. Whatever the nature and form of a charger, whether single or dual battery for the presentation of the ammunition to be fed, the snap or lock of the charger in working position will be according to what comes to be described.
