[0001] DESCRIPTION

[0002] FIREARM AND GUN ACCESSORY

[0003] TECHNICAL FIELD OF THE INVENTION

[0004] The present invention relates to a firearm accessory and a firearm. It applies, in particular, to the field of hunting and sport or military shooting. It is more particularly concerned with the recovery of cartridge cases during shooting.

[0005] STATE OF THE ART

[0006] When firing a firearm with a case ejection port (also called a "case"), a casing is ejected from the weapon. This stray casing risks injuring a person in front of the ejection port and polluting the environment. In addition, its high temperature can cause burns. To avoid polluting the environment, the shooter is forced to bend down and search for the casing to pick it up. Often, because the shooter has moved between shots, the search for stray casings is in vain. In addition, during the search, this phase of inattention to people and animals nearby can contribute to the occurrence of an accident, for example if the shooter is surprised by noises in the surrounding foliage.

[0007] International patent application WO 2022 / 090 088, US patent application US 2015 / 316 338 and US patent 7,941,961 are known, which disclose cartridge case recovery devices.

[0008] STATEMENT OF THE INVENTION

[0009] The present invention aims to remedy all or part of these drawbacks.

[0010] To this end, according to a first aspect, the present invention relates to an accessory for a firearm of predetermined geometry comprising a case ejection window defining a path for a case ejected from this firearm during firing, which comprises:

[0011] - a permanent magnet, and

[0012] - a support fixed to the firearm, configured to position a surface of the permanent magnet in the path of the casing or at the tangent of the path of the casing, the support comprises a mounting plate fixed to the firearm and a removable mounting support carrying the magnet, the mounting support being configured to be secured to the mounting plate in several respective positions along an axis parallel to the axis of the barrel of the firearm, the mounting support being configured to be secured to the mounting plate in several respective positions in a plane perpendicular to the axis of the barrel of the firearm. Thanks to these arrangements, when the casing is ejected, its metallized part passes close to the permanent magnet and is retained on the surface of this magnet. The user can thus retrieve the casing by hand directly from his firearm, without having to bend down or look for where the casing is located.Additionally, the mounting bracket, and thus the magnet, may be positioned more or less forward or rearward of the ejection port and the mounting bracket, and thus the magnet, may be positioned more or less below the ejection port. In embodiments, the bracket is configured to move the magnet away from the case ejection port by a distance at least fifty percent greater than the diameter of a case used by the firearm.

[0013] Thanks to these arrangements, once a casing is magnetically attached to the magnet, another casing can be ejected through the ejection window without the risk of it getting stuck in the window. This other casing thus bounces off the first.

[0014] In embodiments, the support comprises an arm rotatable about an axis parallel to the axis of the barrel of the firearm.

[0015] In embodiments, the bracket includes an arm orientation lock.

[0016] With each of these arrangements, the user can position the magnet more or less opposite the case ejection window and more or less in the case path. Then, he can lock this position.

[0017] In embodiments, the mounting bracket includes one of a toothed wheel or a detent and the mounting plate includes the other of the toothed wheel or the detent, the detent engaging between two teeth of the toothed wheel to define a plurality of respective positions about an axis parallel to the axis of the firearm barrel.

[0018] Thanks to these provisions, the position of the mounting bracket relative to the mounting plate resists vibrations caused by the actuation of the firearm.

[0019] In embodiments, the mechanical connection between the mounting bracket and the mounting plate is a screw attachment, wherein the mounting bracket and / or the mounting plate has at least three screw passage openings.

[0020] Thanks to these provisions, the user can easily change the respective position of the mounting bracket and the mounting plate.

[0021] In embodiments, the magnet holder supports at least one magnet rotating about an axis of rotation parallel to the axis of the firearm barrel.

[0022] By virtue of these arrangements, the assembly of one or more magnets can retain a plurality of casings by rotation between two ejections of casings, the ejection of a casing causing the rotation of this assembly of one or more magnets. According to a second aspect, the present invention relates to a firearm comprising a casing ejection window defining a path for a casing ejected from this firearm during firing, which comprises:

[0023] - a permanent magnet, and

[0024] - a holder configured to position a surface of the permanent magnet in the path of the cartridge case or at the tangent of the path of the cartridge case, the holder comprises a mounting plate fixed on the firearm and a removable mounting bracket carrying the magnet, the mounting bracket being configured to be secured to the mounting plate at several respective positions along an axis parallel to the axis of the barrel of the firearm, the mounting bracket being configured to be secured to the mounting plate at several respective positions in a plane perpendicular to the axis of the barrel of the firearm.

[0025] The advantages, aims and particular characteristics of this firearm being identical to those of the accessory which is the subject of the invention, they are not recalled here.

[0038] DESCRIPTION OF EMBODIMENTS

[0039] This description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

[0040] Throughout the description, the term "top" or "upper" refers to that which is at the top when the user carries the firearm in a standing shooting position, generally at the shoulder or in the hand. An arrow referenced "H" indicates the top in each figure: this is the top in Figure 1. The term "bottom" or "lower" refers to that which is at the bottom in these figures and when the firearm is carried by the user standing in a normal shooting position. The concepts of vertical and height follow from these definitions.

[0041] The term "front" refers to what is in front of the user in a normal standing shooting position, and "behind" refers to what is behind or behind the user. The term "front" refers to what is seen when looking towards the user from in front of him, and "back" refers to what is seen when looking towards the user from behind him. Lengths are measured parallel to the barrel of the firearm, and widths are measured in a direction perpendicular to the barrel and vertically. An arrow marked "H" indicates the direction of measurement of lengths in the figures. An arrow marked "I" indicates the direction of measurement of widths in the figures. The term "internal" refers to what is close to or facing the barrel or stock of the firearm, and "external" refers to what is further away from or facing away from the firearm.

[0042] In Figure 1, we see a firearm 15, of the rifle type, equipped with a barrel 16, a stock 17 and a case ejection window 18 (also called a "case"). The case (not shown) follows a path 19 once it has exited through the election window 18. A firearm accessory 20 carries a magnet 21, one surface of which is located in the path 19 or at the tangent to this path 19.

[0043] Although Figure 1 shows a shoulder-carried firearm, such as a rifle, the present invention is readily adaptable to other types of firearms having a cartridge case ejection port, such as a pistol.

[0044] In the embodiments described with reference to Figures 2 to 11, the support 20 comprises an arm that can rotate about an axis parallel to the axis of the barrel of the firearm 15. Preferably, this support 20 comprises a locking of the orientation of the arm. Thus, the user can position the magnet more or less opposite the case ejection window and more or less in the case path. Then, he can lock this position. However, in other embodiments (not shown), the support of the magnet is rigid and the position of the magnet relative to the ejection window 18 is fixed and frozen according to the position of the mechanical connection between the accessory and the firearm 15.

[0045] In figures 2 to 10, we observe an accessory 20 which comprises:

[0046] - a permanent magnet 21, for example machined and based on neodymium and, more particularly, neodymium, iron and boron,

[0047] - a receiver 22 of the magnet 21, for example made of machined aluminum,

[0048] - a mounting bracket 30, for example made of machined aluminum,

[0049] - screws 28 and 29, preferably with countersunk heads, for example in stainless steel,

[0050] - a mounting plate 35, for example made of machined aluminum, and

[0051] - a 25 mounting key, of a type known in hardware stores.

[0052] The receiver 22 comprises a housing for the magnet 21 and arms 23 (here two) extending perpendicularly to this housing and comprising circular through openings 24, with an axis 27. The mounting support 30 comprises a plate provided with through openings 31 and 32 for the passage of the threads of the screws 28 and 29. The mounting support 30 is also provided with arms (here three) extending perpendicularly to the plate and comprising cylindrical through openings 34 of the same diameter as the through openings 24. The through openings 34 are positioned on an axis 33.

[0053] In embodiments, a seal, such as a rubber washer, is placed around at least one through opening 34, 31 and 32 to increase the coefficient of friction between the arms and provide locking.

[0054] In embodiments shown in Figure 12, the receiver 122 includes a magnet housing and an arm 123 extending perpendicular to the magnet housing. The magnet housing includes a shoulder against which the magnet is positioned. The arm 123 has a through opening in which is positioned a toothed wheel 125 configured to define as many predetermined positions of the receiver 122 as there are notches on the toothed wheel 125. The mounting support 130 has a plate provided with through openings 131 and 132 for the passage of the threads of the screws 28 and 29. The mounting support 130 is also provided with an arm 124 extending perpendicular to the plate and having a cylindrical through opening of the same diameter as the through opening of the arm 123 of the receiver 122. The arm 124 is provided with a notch engaging between at least two teeth of the toothed wheel 125.In other embodiments, the arm 124 of the plate 130 comprises the toothed wheel 125 and the arm 123 of the receiver 122 comprises the notch engaging between at least two teeth of the toothed wheel 125. The embodiments of the receiver, 22 and 122, and of the plate 30, and 130, are compatible. Thus, in the following and preceding description, receiver 122, and the plate 130, have the optional characteristics described with respect to the receiver 22 and the plate 30 and are compatible with the embodiments described with respect to FIGS. 1 to 11.

[0055] The mounting plate 35 is fixed to the receiver below the ejection window 18 of the firearm 15, for example with double-sided adhesive to avoid damaging the weapon. Alternatively, the mounting plate is fixed above, in front of or behind this window 18. Alternatively, the fixing is done with glue or by tapping the receiver of the weapon and fixing with screws. The magnet 21 is fixed to the receiver 22 with strong double-sided tape, to allow it to be changed if one day the magnet is damaged. Alternatively, the magnet 21 is glued or held with a rubber strap or the magnet is tapped for fixing with screws passing through the appropriate part of the receiver 22. The magnet 21 can also be taped and screwed onto the receiver 22.The key 25 locks the position of the receiver 22 using the part 26 which is a threaded rod and which screws into the last (the rightmost in figure 2) through opening 34 of the mounting support 30. The threaded rod 26 thus serves as a tightening bolt.

[0056] Preferably, the support consisting of the receiver 22, the mounting bracket 30 and the mounting plate 35 is configured to move the magnet 22 away from the case ejection window 18 by a distance at least fifty percent greater than the diameter of a case used by the firearm and, preferably, at least twice this diameter. Thus, once a case is magnetically fixed on the magnet, another case can be ejected through the ejection window without risk of getting stuck in this window. This other case thus bounces off the first.

[0057] The key 25 has a handle and a cylindrical shaft 26 with a circular section whose diameter is, within a clearance, equal to the diameter of the through openings 24 and 34. The mounting plate 35 is in the form of a rectangular parallelepiped and has tapped holes 36 (here six) whose thread corresponds to the thread of the screws 28 and 29. The distance between the axes of these tapped holes 36 is regular and equal to one third of the distance between the axes of the through openings 31 and 32. Depending on the choice of the tapped holes 36 in which the screws 28 and 29 are inserted, the mounting support 30 can take three positions on the mounting plate 35, respectively illustrated in figures 4, 8 and 9.

[0058] In embodiments, the mounting plate 35 has a number of tapped holes 36 other than six and / or the distance between these tapped holes 36 is a fraction (e.g., a half or a quarter) other than a third of the distance between the axes of the through-openings 31 and 32. Thus, the number of respective positions between the mounting bracket 30 and the mounting plate 35 may be other than three. In embodiments, the mounting bracket 30 has more than two through-openings and the choice of the through-openings that actually receive the screws makes it possible to modify the respective position of the mounting bracket 30 and the mounting plate 35.

[0059] More generally, the mechanical connection between the mounting bracket 30 and the mounting plate 35 is a screw fixing, the mounting bracket 30 and / or the mounting plate 35 having at least three screw passage openings 28 and 29. The user can thus easily modify the respective position of the mounting bracket 30 and the mounting plate 35.

[0060] In embodiments, the mounting bracket 30 comprises more than one row of through-openings 31 and 32, these rows being parallel and offset from each other in a plane perpendicular to the axis of the barrel of the firearm. These embodiments make it possible to modify, in this plane, the respective position of the mounting bracket 30 and the mounting plate 35. In embodiments, the mounting plate 35 comprises more than one row of tapped holes 36, these rows being parallel and offset from each other in a plane perpendicular to the axis of the barrel of the firearm. These embodiments also make it possible to modify, in this plane, the respective position of the mounting bracket 30 and the mounting plate 35. More generally, the mounting bracket 30 is configured to be secured to the mounting plate 35 in several respective positions in a plane perpendicular to the axis of the barrel 16 of the firearm 15.Thus, the mounting bracket 30, and therefore the magnet 21, can be positioned more or less below the ejection window 18.

[0061] Of course, the rows of through openings 31 and 32 and tapped holes 36 can be replaced by rails, for example dovetail, associated with a screw for locking the position of the mounting bracket 30 in the mounting plate 35.

[0062] Thus, the magnet holder 21 comprises a mounting plate 35 fixed to the firearm 15 and a removable mounting bracket 30 carrying the magnet 21, the mounting bracket 30 being configured to be secured to the mounting plate 35 in several respective positions along an axis parallel to the axis of the barrel 16 of the firearm 15.

[0063] As illustrated in Figures 4 to 10, once the magnet 21 is mounted in the receiver housing 22, when the axes 27 and 33 are made to coincide and the shaft 26 of the key 25 is inserted into the through openings 24 and 34 and the screws 28 and 29 into two of the tapped holes 36, through the through openings 31 and 32, respectively, the accessory is mounted.

[0064] As illustrated in Figure 10, the receiver 22 can take different angular positions relative to the mounting bracket 30 and the mounting plate 35. The user can thus adjust the position of the magnet 21 relative to the socket path 19. To this end, the user unlocks the key 25, orients the receiver 22 in the position which suits him then relocks the key 25. In Figures 2 to 9, the accessory 20 is in a planar configuration, the arms 23 of the receiver 22 being parallel to the arms of the mounting bracket 30.

[0065] Thanks to the two or three settings:

[0066] - longitudinal, by the choice of the tapped holes 36 of a row into which the screws 28 and 29 are inserted and / or the through openings of the mounting support 30 through which the screws 28 and 29 are inserted,

[0067] - angular by the action of key 25, and

[0068] - possibly laterally, by choosing one, among several, rows of tapped holes 36 into which the screws 28 and 29 are inserted and / or one, among several, rows of through openings of the mounting bracket 30 through which the screws 28 and 29 are inserted, the position of the magnet 21 in the sleeve path 19 can be adapted to all the sleeve paths, after rough mounting of the mounting plate 35 on the stock of the firearm 15.

[0069] In a first variant illustrated in Figure 11, the accessory 40 comprises the magnet 21 mounted on a shaft 41 freely rotating relative to a receiver 42, otherwise similar to the receiver 22 described above, the other parts of the accessory 40 being identical to those of the accessory 20. In this variant, when a casing reaches the magnet 21 and attaches to it by the effect of the magnetic field, its momentum causes the rotation of the magnet 21, so that another casing can then attach to the magnet 21. The user can therefore perform several shots before recovering the casings attached to the magnet 21. In a second variant (not shown), the magnet 21 is replaced by several smaller magnets mounted on a support comprising the shaft 41. Machining the parts of this second variant can be easier than that of the first variant illustrated in Figure 11.

[0070] As understood from reading the foregoing description, the accessory which is the subject of the invention is geometrically defined for a type of firearm of predetermined geometry comprising a case ejection window defining a path for a case ejected from this firearm during firing.

[0071] This accessory mainly includes:

[0072] - a permanent magnet, and

[0073] - a mount attached to the firearm, configured to position a surface of the permanent magnet in the path of the case or at a tangent to the path of the case.

[0074] The mount may be rigid or, as described above, have adjustments to its geometry to be adaptable to several types of firearms and / or to different positions of the mount attachment on the firearm.

[0075] Thus, when the casing is ejected, its metallized part passes close to the permanent magnet and is retained on the surface of this magnet. The user can thus retrieve the casing by hand directly from his firearm, without having to bend down or look for where the casing is located. According to a second aspect, the present invention relates to a firearm 15 comprising a casing ejection window 18 defining a path 19 for a casing ejected from this firearm during a shot. This firearm 15 comprises a permanent magnet 21, and a support 22, 30, 35 configured to position a surface of the permanent magnet 21 in the path 19 of the casing or at the tangent of the path 19 of the casing.
