ACCESSORIES FOR A FIREARM AND FIREARM

Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to a firearm accessory and a firearm. It is particularly applicable to the fields of hunting and sport or military shooting. It is of particular interest for the recovery of spent cartridges after firing. STATE OF THE ART

[0002] When firing a firearm with a spent casing (also called a shell casing), a spent casing is ejected from the weapon. This lost casing can injure anyone standing in front of the ejection port and pollute the environment. Furthermore, its high temperature can cause burns. To avoid environmental pollution, the shooter is obliged to bend down and search for the casing to pick it up. Often, because they have moved between shots, the search for the lost casing proves fruitless. Moreover, during the search, this period of inattention to people and animals nearby can contribute to an accident, for example, if the shooter is startled by noises in the surrounding foliage.

[0003] We know of International Patent Application WO 2022 / 090 088, US Patent Application US 2015 / 316 338 and US Patent 7 941 961 which disclose cartridge case recovery devices. DESCRIPTION OF THE INVENTION

[0004] The present invention aims to remedy all or part of these drawbacks.

[0005] Accordingly, in a first aspect, the present invention relates to an accessory for a firearm of predetermined geometry comprising a cartridge case ejection window defining a path for a cartridge case ejected from this firearm during firing, which comprises: a permanent magnet, and a bracket fixed to the firearm, configured to position a surface of the permanent magnet in the path of the cartridge case or tangent to the path of the cartridge case, the bracket includes a mounting plate fixed to the firearm and a removable mounting bracket carrying the magnet, the mounting bracket 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 bracket 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.

[0006] Thanks to these arrangements, during cartridge case ejection, its metallized portion passes close to the permanent magnet and is held against its surface. The user can thus retrieve the cartridge case directly from their firearm, without having to bend down or search for it. Furthermore, the mounting bracket, and therefore the magnet, can be positioned more or less in front of or behind the ejection port, and also more or less below the ejection port. In some embodiments, the bracket is configured to position the magnet at least fifty percent further from the cartridge case ejection port than the diameter of a cartridge case used by the firearm.

[0007] Thanks to these features, once a cartridge case is magnetically attached to the magnet, another case can be ejected through the ejection port without risk of getting stuck. This second case then bounces off the first.

[0008] In some embodiments, the support includes an arm that can be steered around an axis parallel to the axis of the gun barrel.

[0009] In some embodiments, the support includes a locking mechanism for the orientation of the arm.

[0010] With each of these adjustments, the user can position the magnet more or less in relation to the socket ejection window and more or less in the socket path. Then, they can lock this position.

[0011] In some embodiments, the mounting support comprises one element from a toothed wheel or a notch and the mounting plate comprises the other element from the toothed wheel or the notch, the notch engaging between two teeth of the toothed wheel to define several respective positions around an axis parallel to the axis of the gun barrel.

[0012] Thanks to these provisions, the position of the mounting bracket relative to the mounting plate resists vibrations caused by the firing of the firearm.

[0013] In some embodiments, the mechanical connection between the mounting bracket and the mounting plate is a screw fixing, the mounting bracket and / or the mounting plate having at least three screw passage openings.

[0014] Thanks to these provisions, the user can easily change the respective position of the mounting bracket and the mounting plate.

[0015] In some embodiments, the magnet support supports at least one magnet rotating about an axis of rotation parallel to the axis of the gun barrel.

[0016] Thanks to these arrangements, the assembly of one or more magnets can retain a plurality of sockets by rotation between two ejections of sockets, the ejection of a socket causing the rotation of this assembly of one or more magnets.

[0017] According to a second aspect, the present invention relates to a firearm comprising a cartridge case ejection port defining a path for a cartridge case ejected from this firearm during firing, which comprises: a permanent magnet, and a support configured to position a surface of the permanent magnet in the path of the cartridge case or tangent to the path of the cartridge case, the support comprising a mounting plate fixed to the firearm and a removable mounting bracket carrying the magnet, the mounting bracket 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 bracket 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.

[0018] The advantages, purposes and special characteristics of this firearm being identical to those of the accessory which is the subject of the invention, they are not recalled here. BRIEF DESCRIPTION OF THE FIGURES

DESCRIPTION OF IMPLEMENTATION METHODS

[0020] The present description is given by way of non-limiting attribution, each feature of an embodiment being able to be advantageously combined with any other feature of any other embodiment.

[0021] Throughout this description, "top" or "upper" refers to the position at the top when the user is holding the firearm in the upright firing position, typically shouldered or handed. An arrow labeled "H" indicates the top in each figure: this is the top in figure 1 The term "low" or "lower" refers to the point at the bottom of these figures when the firearm is held by the user standing in a normal firing position. The concepts of vertical and height are derived from these definitions.

[0022] The term "front" refers to what is in front of the user in the normal standing firing position, and "back" refers to what is behind or to the user's back. The term "facing" refers to what is seen when looking towards the user from the front, and "rear" refers to what is seen when looking towards the user from the back. Lengths are measured parallel to the barrel of the firearm, and widths are measured perpendicular to the barrel and vertically. An arrow labeled "H" indicates the direction of length measurement in the figures. An arrow labeled "I" indicates the direction of width measurement in the figures. The term "internal" refers to what is close to or facing the barrel or stock of the firearm, and the term "external" refers to what is farther away from or facing away from the firearm.

[0023] We observe, in figure 1A firearm 15, of the rifle type, equipped with a barrel 16, a stock 17, and a cartridge case ejection port 18. The cartridge case (not shown) follows a path 19 once it exits through the ejection port 18. A firearm accessory 20 carries a magnet 21, one surface of which lies in the path 19 or at the tangent to this path 19.

[0024] Although, in the figure 1 , where a firearm carried on the shoulder, for example a rifle, has been represented, the present invention is easily adapted to other types of firearms having a cartridge case ejection window, for example a pistol.

[0025] In the embodiments described opposite the figures 2 to 11The support 20 includes an arm that can be rotated about an axis parallel to the axis of the barrel of the firearm 15. Preferably, this support 20 includes a locking mechanism for the arm's orientation. This allows the user to position the magnet more or less directly opposite the ejection port and more or less within the cartridge case path. This position can then be locked. However, in other embodiments (not shown), the magnet support is rigid, and the position of the magnet relative to the ejection port 18 is fixed and determined by the position of the mechanical linkage between the accessory and the firearm 15.

[0026] We observe, in figures 2 to 10 , an accessory 20 which includes: a permanent magnet 21, for example machined and based on neodymium and, more particularly, on neodymium, iron and boron, a magnet receiver 22, for example machined aluminum, a mounting bracket 30, for example machined aluminum, screws 28 and 29, preferably with countersunk heads, for example stainless steel, a mounting plate 35, for example machined aluminum, and a mounting wrench 25, of a type known in hardware.

[0027] The receiver 22 has a housing for the magnet 21 and arms 23 (here two) extending perpendicularly from this housing and having circular through-holes 24 with axis 27. The mounting bracket 30 has a plate with through-holes 31 and 32 for the threads of the screws 28 and 29. The mounting bracket 30 also has arms (here three) extending perpendicularly from the plate and having cylindrical through-holes 34 of the same diameter as the through-holes 24. The through-holes 34 are positioned on an axis 33.

[0028] In some embodiments, a seal, such as a rubber washer, is placed around at least through openings 34, 31 and 32 in order to increase the coefficient of friction between the arms and ensure a lock.

[0029] In embodiments represented in figure 12The receiver 122 has a housing for the magnet and an arm 123 extending perpendicularly to this housing. The housing for the magnet has a shoulder against which the magnet is positioned. The arm 123 has a through opening in which a toothed wheel 125 is positioned, configured to define as many predetermined positions of the receiver 122 as there are notches on the toothed wheel 125. The mounting bracket 130 has a plate with through openings 131 and 132 for the threads of the screws 28 and 29. The mounting bracket 130 also has an arm 124 extending perpendicularly 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 has a notch that engages between at least two teeth of the toothed wheel 125.In other embodiments, the arm 124 of the plate 130 includes the toothed wheel 125, and the arm 123 of the receiver 122 includes the notch engaging between at least two teeth of the toothed wheel 125. The embodiments of the receiver, 22 and 122, and of the plates 30 and 130, are compatible. Thus, in the description that follows and precedes, the receiver 122 and the plate 130 have the optional features described opposite the receiver 22 and the plate 30 and are compatible with the embodiments described opposite them. figures 1 to 11 .

[0030] The mounting plate 35 is attached to the receiver below the ejection port 18 of the firearm 15, for example, with double-sided adhesive to avoid damaging the firearm. Alternatively, the mounting plate is attached above, in front of, or behind this port 18. The attachment can also be made with glue or by tapping the receiver and securing it with screws. The magnet 21 is attached to the receiver 22 with strong double-sided tape, allowing it to be replaced if the magnet is ever damaged. Alternatively, the magnet 21 can be glued or held in place with a rubber strap, or the magnet can be tapped for fixing with screws through the appropriate part of the receiver 22. The magnet 21 can also be tapped and screwed onto the receiver 22. The key 25 locks the position of the receiver 22 by means of part 26, which is a threaded rod that screws into the last (rightmost) part. figure 2) through opening 34 of the mounting support 30. The threaded rod 26 thus serves as a clamping bolt.

[0031] Preferably, the support consisting of the receiver 22, the mounting bracket 30, and the mounting plate 35 is configured to position the magnet 22 away from the cartridge case ejection port 18 by a distance at least fifty percent greater than the diameter of a cartridge case used by the firearm, and preferably at least twice that diameter. Thus, once a cartridge case is magnetically attached to the magnet, another cartridge case can be ejected through the ejection port without risk of jamming. This second cartridge case then rebounds off the first.

[0032] The wrench 25 has a handle and a cylindrical shaft 26 with a circular cross-section, the diameter of which is, within a certain amount of play, equal to the diameter of the through openings 24 and 34. The mounting plate 35 is rectangular and has tapped holes 36 (here six) whose threads correspond to the threads 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 tapped holes 36 into which the screws 28 and 29 are inserted, the mounting bracket 30 can assume three positions on the mounting plate 35, respectively illustrated in figures 4 , 8 And 9 .

[0033] In some embodiments, the mounting plate 35 has a different number of tapped holes 36 than six and / or the distance between these tapped holes 36 is another fraction (for example, one half or one quarter) than one third of the distance between the axes of the through openings 31 and 32. Thus, the number of respective positions between the mounting support 30 and the mounting plate 35 may be different from three.

[0034] In some embodiments, the mounting bracket 30 has more than two through openings and the choice of through openings which actually receive the screws allows the respective position of the mounting bracket 30 and the mounting plate 35 to be changed.

[0035] 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 change the respective position of the mounting bracket 30 and the mounting plate 35.

[0036] In some embodiments, the mounting bracket 30 has more than one row of through-holes 31 and 32, these rows being parallel and offset from each other in a plane perpendicular to the axis of the firearm barrel. These embodiments allow the respective positions of the mounting bracket 30 and the mounting plate 35 to be modified in this plane. In some embodiments, the mounting plate 35 has 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 firearm barrel. These embodiments also allow the respective positions of the mounting bracket 30 and the mounting plate 35 to be modified in this plane. 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 firearm barrel 16.Thus, the mounting bracket 30, and therefore the magnet 21, can be positioned more or less below the ejection window 18.

[0037] Of course, the rows of through openings 31 and 32 and threaded holes 36 can be replaced by rails, for example dovetail rails, associated with a locking screw for the position of the mounting support 30 in the mounting plate 35.

[0038] Thus, the magnet support 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.

[0039] As illustrated in figures 4 to 10, once the magnet 21 is mounted in the housing of the receiver 22, when the axes 27 and 33 are aligned 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.

[0040] As illustrated in Figure 10 The receiver 22 can assume various 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 track 19. To do this, the user unlocks the key 25, orients the receiver 22 into the desired position, and then relocks the key 25. In the figures 2 to 9 , accessory 20 is in planar configuration, the arms 23 of receiver 22 being parallel to the arms of mounting support 30.

[0041] Thanks to the two or three settings: longitudinal, by the choice of the tapped holes 36 of a row into which the screws 28 and 29 are inserted and / or of the through openings of the mounting support 30 through which the screws 28 and 29 are inserted, angular by the action of the key 25, and possibly laterally, by the choice of one, among several, row of tapped holes 36 into which the screws 28 and 29 are inserted and / or of one, among several, row of through openings of the mounting support 30 through which the screws 28 and 29 are inserted, the position of the magnet 21 in the socket track 19 can be adapted to all socket tracks, after rough mounting of the mounting plate 35 on the stock of the firearm 15.

[0042] In a first variant illustrated in figure 11Accessory 40 comprises a magnet 21 mounted on a shaft 41 that rotates freely relative to a receiver 42, which is otherwise similar to the receiver 22 described above. The other parts of accessory 40 are identical to those of accessory 20. In this variant, when a spent cartridge reaches the magnet 21 and becomes attached to it by the magnetic field, its momentum causes the magnet 21 to rotate, allowing another cartridge to then attach to it. The user can therefore fire several shots before retrieving the cartridges attached to the magnet 21. In a second variant (not shown), the magnet 21 is replaced by several smaller magnets mounted on a support incorporating the shaft 41. Machining the parts of this second variant may be easier than machining the parts of the first variant illustrated in Figure 1. figure 11 .

[0043] As can be understood from the preceding description, the accessory which is the subject of the invention is geometrically defined for a type of firearm of predetermined geometry comprising a cartridge case ejection window defining a path of a cartridge case ejected from this firearm during firing.

[0044] This accessory mainly includes: a permanent magnet, and a bracket fixed to the firearm, configured to position a surface of the permanent magnet in the path of the cartridge case or tangent to the path of the cartridge case.

[0045] The mount can be rigid or, as described above, have adjustments to its geometry to be adaptable to several types of firearms and / or different positions of the mount's attachment to the firearm.

[0046] Thus, when the spent casing is ejected, its metallic part passes close to the permanent magnet and is held onto its surface. The user can then retrieve the casing by hand directly from their firearm, without having to bend down or search for it.

[0047] According to a second aspect, the present invention relates to a firearm 15 comprising a cartridge case ejection port 18 defining a path 19 of a cartridge case ejected from this firearm during firing. This firearm 15 includes 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 cartridge case or tangent to the path 19 of the cartridge case.
