Description

[0001] The present invention relates to a cartridge case recovery device for a firearm. More specifically, said cartridge case recovery device is suitable for an assault rifle.

[0002] During shooting training exercises, whether in a shooting range or in nature, it is increasingly common to have to recover the casings of the cartridges fired in order to protect the environment but also in order to control the number of cartridges fired.

[0003] In order to avoid having to pick up the casings ejected from the firearm from the ground, it is known to fit a casing recovery device to the firearm at the ejection window of the firearm. A casing recovery device generally comprises a rigid support provided with means for attachment to the firearm and a storage pocket fixed around the rigid support. Said pocket has an opening intended to be presented opposite the casing ejection window of said firearm so that the casings enter the storage pocket.

[0004] Such case recovery devices also prevent ejected cases from reaching and injuring a person close to the shooter and located in the case ejection line.

[0005] However, in order to have visual or manual access to the ejection port, for example to remove a jammed cartridge case or to visually check for the presence of a bullet in the firing chamber, it is necessary to completely remove the cartridge case catcher. In addition, in order to withstand the ejection force of the cartridge cases, the attachment of the cartridge case catcher to the firearm must be strong, which can be difficult, particularly due to the design differences between different firearm models.

[0006] Additionally, in combat or shooting situations, the shooter must be able to use his weapon in various positions, such as tilted forward, backward, or even sideways. This adds further constraints to the shell casing catcher, which must be effective in all these shooting positions.

[0007] One of the aims of the present invention is therefore to at least partially remedy the drawbacks of the prior art and to propose an improved cartridge case recovery device. US7168200 represents the relevant state of the art.

[0008] The present invention therefore relates to a device for recovering cartridge cases for a firearm comprising a window for ejecting cartridge cases from fired cartridges, said device for recovering cartridge cases comprising a recovery chamber and a storage pocket integral with each other and movable between a position for recovering the cases in which the recovery chamber is intended to be opposite the ejection window and a released position in which the ejection window is intended to be released,

[0009] the recovery chamber comprising: a first opening intended to come opposite the ejection window in the recovery position, and a second opening connected to the storage pocket, the cartridge case recovery device further comprising: a fixing plate arranged laterally relative to the recovery chamber and comprising a first device for connection to the firearm, and a second device for connection between the fixing plate and the recovery chamber, said second connection device comprising: at least one slide, and at least one slide, arranged complementary and in which said slide is guided between a first position in which the case recovery device is in the recovery position and a second position in which the case recovery device is in the released position.

[0010] According to one aspect of the invention, the recovery chamber comprising: a first face called the front, comprising the first opening, a second face called the rear, arranged opposite the first face, a third face called the upper face, connecting an upper edge of the first face to an upper edge of the second face, a fourth face called the lower face, connecting a lower edge of the first face to a lower edge of the second face, said fourth face comprising the second opening connected to the storage pocket, two fifth faces called the side faces, connecting side edges of the first face, the second face, the upper face and the lower face, and the fixing plate being arranged laterally relative to the recovery chamber and the second connection device being arranged on one of the fifth lateral faces of the recovery chamber.

[0011] According to another aspect of the invention, the first firearm connection device comprises a jaw attachment configured to hook onto a mounting rail.

[0012] According to another aspect of the invention, the first device for connecting to the firearm comprises at least one positioning interface providing the connection between the fixing plate and a means of attachment to the fixing rail.

[0013] According to another aspect of the invention, the at least one slide of the second connection device comprises a first portion configured to, in the mounted state, translate the recovery chamber and the storage pocket perpendicular to the plane of the firearm, so as to create a space between the first opening and the ejection window.

[0014] According to another aspect of the invention, the at least one slide of the second connection device comprises a second portion contiguous to the first portion and configured to, in the mounted state, translate the recovery chamber and the storage pocket parallel to the plane of the firearm, so as to release the recovery chamber from the ejection window.

[0015] According to another aspect of the invention, the first portion of the at least one slide of the second connection device comprises a recess at one of its ends so that the slide is positioned in said recess in the recovery position.

[0016] According to another aspect of the invention, the casing recovery device comprises a device for locking the recovery chamber and the storage pocket in the recovery position.

[0017] According to another aspect of the invention, the second connection device comprises at least two slider / slider pairs parallel to each other.

[0018] According to another aspect of the invention, the recovery chamber comprises within it an inclined wall arranged opposite the first face of the recovery chamber so that said first face and said inclined wall form a funnel converging towards the second opening.

[0019] According to another aspect of the invention, the gap between the lower edge of the first face of the recovery chamber and the lower edge of the inclined wall at the second opening is greater than up to 30% of the diameter of the casings intended to be recovered.

[0020] According to another aspect of the invention, the attachment of the storage bag to the first face of the recovery chamber is offset forward so that the attachment of the storage bag to the first front face is spaced from the edge of the second opening.

[0021] According to another aspect of the invention, one of the external walls of the recovery chamber is translucent.

This indexing also does not imply an order in time, for example, to assess this or that criterion.

[0026] THE figures 1a et 1b show a firearm 100, of the assault rifle type, comprising a casing recovery device 1 arranged opposite the ejection window 110 (visible on the figure 1b ) of casings of the fired cartridges. This ejection window 110 is more precisely arranged on a lateral part of the firearm 100.

[0027] The firearm 100 also includes at least one mounting rail 104, such as a Picatinny rail, on which the user can install accessories such as a sighting optic. In the example illustrated in figures 1a et 1b , the firearm 100 notably comprises several fixing rails 104 including in particular upper, lower and lateral fixing rails.

[0028] The case recovery device 1 more precisely comprises a recovery chamber 2 and a storage pocket 3 secured to each other. The recovery chamber 2 and the storage pocket 3 are movable between a case recovery position in which the recovery chamber 2 is intended to be opposite the ejection window 110, illustrated in figure 1a , and a disengaged position in which the ejection window 110 is intended to be disengaged, illustrated in figure 1b .

[0029] The recovery chamber 2 comprises a first opening 21 intended to come opposite the ejection window 110 in the recovery position, and a second opening 22 connected to the storage pocket 3. The case recovery device 1 further comprises a fixing plate 4 arranged laterally with respect to the recovery chamber 2 and comprising a first connection device 5 to the firearm 100. The case recovery device 1 also comprises a second connection device between the fixing plate 4 and the recovery chamber 2, one of the fifth lateral faces 2e of the recovery chamber 2.

[0030] The second connection device comprising at least one slider 41, and at least one slide 42, arranged complementary and in which said slider 41 is guided between a first position in which the case recovery device 1 is in the recovery position and a second position in which the case recovery device 1 is in the released position.

[0031] As shown in the figure 1a , in the recovery position, the casings ejected by the firearm 100 at its ejection window 110 are received by the recovery chamber 2 and are stored in the storage pocket 3. In the disengaged position, as illustrated in figure 1b , the recovery chamber 2 is moved relative to the ejection window 110 in order to allow access to the latter by the user in order, for example, to carry out a visual check of the ejection window or possibly to intervene on the latter in the event of a firing incident, without it being necessary to dismantle and detach the casing recovery device 1.

[0032] As illustrated in figures 2a à 3b , the recovery chamber 2 more particularly comprises a first face 2a called front, a second face 2b called rear, a third face 2c called upper, a fourth face 2d called lower and two fifth faces 2e called lateral. By front, we mean here that it is an element, here a face of the recovery chamber 2, intended to come opposite the firearm 100. By rear, we mean here an element, here a face of the recovery chamber 2, arranged opposite a front element relative to the firearm 100. By upper, we mean here an element, here a face of the recovery chamber 2, intended to be arranged on the upper part of the recovery chamber 2 in the state mounted on the firearm 100 and when the firearm 100 is held normally.By lower, here is meant an element, here a face of the recovery chamber 2, intended to be arranged opposite the upper element, on the lower part of the recovery chamber 2 in the state mounted on the firearm 100 and when the firearm 100 is held normally. Finally, by lateral, is meant an element arranged on the sides of the front, rear, upper and lower elements simultaneously.

[0033] The first face 2a, called the front face, more particularly comprises the first opening 21 intended to come opposite the ejection window 110 in the recovery position. The dimensions of the first opening 21 are preferably equal to or greater than the ejection window 110 of the firearm 100. This first face 2a may thus comprise a rigid wall in which the first opening 21 is formed. As in the example illustrated in figures 3a et 3b , a rigid wall may only be present on a part of the surface of the first face 2a, the first opening 21 being formed by the free space left by the rigid wall, advantageously on the upper part of the first face 2a. This rigid wall may in particular be made of a plastic material in order to limit the weight of the cartridge case recovery device 1.

[0034] The first face 2a may be inclined relative to the plane of the firearm 100 so that its upper part is closer to the firearm 100 in the mounted state than its lower part. By plane of the firearm 100 is meant the plane passing through the longitudinal axis A (visible in figures 1a and 1b) and passing through a handle 102 and / or an ammunition magazine 103 (visible in figures 1a and 1b). figures 1a et 1b ) of said firearm 100.

[0035] The second face 2b, called the rear face, is arranged opposite the first face 2a. This second face 2b may in particular comprise, over its entire surface, a rigid wall against which the ejected casings are intended to come into contact before falling into the storage pocket 3. This rigid wall may in particular be made of a plastic material in order to limit the weight of the casing recovery device 1. Like the first face 2a, the second face 2b may be inclined relative to the plane of the firearm 100 so that its upper part is closer to the firearm 100 in the mounted state than its lower part.

[0036] The third face 2c, called the upper face, more particularly connects an upper edge of the first face 2a to an upper edge of the second face 2b. This third face 2c may in particular comprise, over its entire surface, a wall, for example a flexible wall, in order to prevent any casings from escaping through the upper face 2c. The fact that this wall is flexible makes it possible to limit the weight of the casing recovery device 1. This flexible wall may in particular be made of a high-strength, fire-retardant fabric.

[0037] The fourth face 2d, called lower, more particularly connects a lower edge of the first face 2a to a lower edge of the second face 2b. The fourth face 2d includes in particular the second opening 22 opening into the storage pocket 3. As illustrated in the figures 3a et 3b , the fourth face 2b can be completely opened.

[0038] The two fifth faces 2e, called lateral faces, connect lateral edges of the first face 2a, of the second face 2b, of the upper face 2c and of the lower face 2d. The case recovery device 1, in particular the recovery chamber 2, being intended to be fixed on a side of the firearm 100, depending on whether the ejection window 110 and therefore the case recovery device 1 is arranged on a right or left side of the firearm 100, one of the two fifth faces 2e is intended to be oriented towards the front of the firearm 100, that is to say towards the ejection mouth of the barrel of the firearm 100. The other fifth face 2e is oriented towards the rear of the firearm 100, that is to say towards the butt of the firearm 100.

[0039] The storage pocket 3 is connected to the fourth face 2d of the recovery chamber 2. The storage pocket 3 has an opening 31 (visible on the figures 3a et 3b ) connected to the second opening 22 of the fourth face 2d. The storage pocket 3 can in particular be made of a high-strength, military-grade fabric and more particularly fireproof in order to withstand the high temperature of the cartridges ejected by the firearm 100.

[0040] As illustrated in figures 1a à 2b , opposite the opening 31 of the storage pocket 3, said storage pocket 3 may comprise a bottom 32 comprising an opening device such as a zipper in order to be able to evacuate the casings and empty the storage pocket 3.

[0041] As shown by the figures 3a et 3b , the recovery chamber 2 may also comprise within it an inclined wall 24 arranged opposite the first face 2a of the recovery chamber 2 so that said first face 2a and said inclined wall 24 form a funnel converging towards the second opening 22. The gap E2 between the lower edge of the first face 2a of the recovery chamber 2 and the lower edge of the inclined wall 24 at the level of the second opening 22 may in particular be greater than 30% of the diameter of the cases intended to be recovered. This funnel formed between the first face 2a and the inclined wall 24 makes it possible to guide the cases into the storage pocket 3 but also prevents the latter from rising into the storage chamber 2 in the event of jolts or when the weapon is tilted forwards or backwards but also to the sides (by a rotation around the axis A of the firearm 100).

[0042] The attachment of the storage pocket 3 with the first face 2a of the recovery chamber 2 can be shifted forward, i.e. outward, so that the attachment of the storage pocket 3 on the first front face 2a is spaced away from the edge of the second opening 22. This offset between the attachment of the storage pocket 3 and the edge of the second opening 22 creates a space between the storage pocket 3 and the second opening 22 which in particular makes it possible to prevent the cartridge cases from rolling and rising through the opening 31 of the storage pocket 3 and the second opening 22 of the recovery chamber 2 when the user tilts the firearm to the side, bringing the cartridge case recovery device 1 on top. The cases thus do not rise into the recovery chamber 2, in this position, and do not hinder the ejection of other cases through the ejection window 110.

[0043] As shown in more detail in the figures 4a à 6b , the cartridge case recovery device 1 further comprises a means of attachment to the firearm 100, movable between the two recovery and released positions. The figures 4a, 4b And 6b show more particularly the cartridge case recovery device 1 in the released position and the figures 5a, 5b And 6a show the cartridge case recovery device 1 in the recovery position.

[0044] This fixing means comprises a fixing plate 4 arranged laterally relative to the recovery chamber 2. This fixing plate 4 comprises a first connection device 5 to the firearm 100. This first connection device 5 to the firearm 100 may in particular comprise a hooking means configured to hook onto a fixing rail 104 of the firearm 100 as illustrated in the figures 4a , 5a And 6a, 6b Advantageously, the fixing rail 104 on which the first connection device 5 is intended to be attached is a lateral rail of the firearm 100 arranged behind the ejection window 110 relative to the user. The first connection device 5 can in particular be fixed to the fixing plate 4 by means of screws or bolts.

[0045] The first connection device 5 may also comprise at least one positioning interface, for example extensions or extensions, making the connection between the fixing plate 4 and the means for attaching to the fixing rail 104. This at least one positioning interface allows the first connection device 5 to attach to the fixing rail 104 regardless of its positioning relative to the ejection window 110. The cartridge case recovery device 1 may thus be adapted to different firearms 100 with fixing rails 104 which may be in the axis of the ejection window 110 or offset relative to the axis of the ejection window 110.

[0046] The attachment means of the first connection device 5 may in particular be a jaw attachment configured to attach to and grip the attachment rail 104.

[0047] The means for attaching the cartridge case recovery device 1 to the firearm 100 further comprises a second connection device between the attachment plate 4 and one of the fifth lateral faces 2e of the recovery chamber 2. Depending on whether the ejection window 110 is placed on the right or left of the firearm 100, the fifth lateral face 2e of the recovery chamber 2 on which the attachment plate 4 is attached will be different so that the first opening 21 of the recovery chamber 2 is opposite the ejection window 110.

[0048] This second connection device comprises at least one slider 41, arranged on one or the other of the fixing plate 4 or one of the fifth lateral faces 2e of the recovery chamber 2, and at least one slide 42, arranged complementary on one or the other of one of the fifth lateral faces 2e of the recovery chamber 2 or of the fixing plate 4. The slider 41 is guided in the slide 42 between a first position in which the case recovery device 1 is in the recovery position and a second position in which the case recovery device 1 is in the released position.

[0049] The second connection device may in particular comprise at least two slide 42 / slider 41 pairs parallel to each other. In the examples illustrated in figures 1a à 6b , the second connection device more particularly comprises three slide 42 / slider 41 pairs parallel to each other in order to ensure good stability and a fluid translational movement to the recovery chamber 2 and to the storage pocket 3.

[0050] In the examples presented to the various figures 1a à 6b , the at least one slide 42 is produced on the fixing plate 4 and the at least one slider 41 is integral with one of the fifth lateral faces 2e of the recovery chamber 2. It is however entirely possible to imagine a second connection device in which the at least one slide 42 is produced on one of the fifth lateral faces 2e of the recovery chamber 2 and where the at least one slider 41 is integral with the fixing plate 4.

[0051] The slides 42 may in particular be grooves provided in the fixing plate 4 or in the fifth lateral wall 2 carrying the second connection device. However, as illustrated in the various figures 4a à 5b , when the slides 42 are produced on the fixing plate 4, one of these slides 42 may not be a groove but an open profile of an edge of the fixing plate 4 having the same shape as the other slides 42 and against which a slider 41 slides.

[0052] The at least one slide 42 of the second connection device 4 may in particular comprise a first portion 42a configured to, in the mounted state, translate the recovery chamber 2 and the storage pocket 3 perpendicular to the plane of the firearm 100, so as to create a space E1 between the first opening 21 and the ejection window 110, as illustrated in figures 6a et 6b This space E1 allows in particular access to the ejection window 110, particularly in the event of a firing incident or to check the latter.

[0053] The at least one slide 42 of the second connection device may also comprise a second portion 42b contiguous to the first portion 42a and configured to, in the mounted state, translate the recovery chamber 2 and the storage pocket 3 parallel to the lateral plane of the firearm 100, so as to disengage the recovery chamber 2 from the ejection window 110. This translation of the recovery chamber 2 and the storage pocket 3 may in particular be oriented towards the bottom of the firearm 100, as illustrated in the figure 1b , in order to completely clear the ejection window 110. This second portion 42b is connected to the end of the first portion 42a of the slide 42 furthest from the first face 2a of the recovery chamber 2. The second portion 42b of the slide 42 can be straight or curved as illustrated in the figures 4a à 5b The second portion 42b of the slide 42 may in particular be inclined towards the first face 2a of the recovery chamber 2 so that in the released position, the recovery chamber 2 and the storage pocket 3 move closer to the side of the firearm 100.

[0054] The first portion 42a of the at least one slide 42 of the second connection device may also comprise a recess 42c at one of its ends so that the slide 41 is positioned in said recess 42c in the recovery position. This recess 42c makes it possible to block the slide 41 in order to maintain the casing recovery device 1 in the recovery position.

[0055] The case recovery device 1 can thus have the following kinematics when it passes from the recovery position to the released position in the state mounted on the firearm 100. Initially, the recovery chamber 2 and the storage pocket 3 are translated parallel to the plane of the firearm 100 upwards, that is to say towards the upper part of the firearm 100. This first translation makes it possible to cause the slide(s) 41 to come out of the recess 42c of the slide(s) 42. The recovery chamber 2 and the storage pocket 3 are then translated perpendicular to the plane of the firearm 100, following the first portion 42a of the slide(s) 42 in order to move the first opening 21 away from the ejection window 110.Then, the recovery chamber 2 and the storage pocket 3 are then translated parallel to the plane of the firearm 100 downwards, following the second portion 42b of the slide(s) 42 in order to completely clear the ejection window 110 so that nothing is facing the latter.

[0056] The kinematics are reversed in order to move the cartridge case recovery device 1 from the released position to the recovery position.

[0057] In order to assist the user in gripping the case recovery device 1 so that the latter can move the case recovery device 1 from one position to another, said case recovery device 1 may comprise a tab 25. This tab 25 may be made, for example, of reinforced fabric. Preferably, in order to limit wobbling, this tab 25 may in particular be fixed to the upper side of the fifth lateral wall 2 carrying the second connection device.

[0058] The cartridge case recovery device 1 may also include a locking device 44 (visible on the figures 6a et 6b) of the recovery chamber 2 and the storage pocket 3 in the recovery position. This locking device 44 may for example be a ball partially protruding from a housing here provided in the body of the first connection device 5. This ball may in particular be held by an elastic means, for example a spring. In the recovery position, the part of this ball protruding from its housing is inserted into a complementary cavity made at the end of a slide 41.

[0059] In order to facilitate visual inspection of the ejection window 110 as well as the interior of the recovery chamber 2, one of the external walls, i.e. the second rear wall 2b, the third upper wall 2c or the fifth lateral wall 2e without the means of attachment to the firearm 100, may be translucent. Preferably, the translucent wall is the fifth lateral wall 2e without the means of attachment to the firearm 100 since the latter is arranged directly opposite the user in the state mounted on the firearm 100.

[0060] Thus, it is clear that the case recovery device 1 allows the cases to be recovered, but that it also allows the latter to be kept in the storage pocket 3 regardless of the orientation of the firearm 100, in particular in order to limit the risks of these cases rising into the recovery chamber 2 and potentially hindering or jamming the ejection window 110. In addition, the fact that the case recovery device 1 has two positions makes it possible, if necessary, to intervene on the ejection window 110 without having to detach the case recovery device 1 from the firearm 100.
