Description

"Mounting assembly, firearm assembly and kit"

DESCRIPTION

[0001] . The present invention relates to a mounting assembly, to a firearm assembly and to a kit comprising said mounting assembly.

[0002] . For certain users, it is a long felt need to provide firearms with certain accessories, such as bipods or flashlights, in a detachable manner so as to make use of these devices just in case of need.

[0003] . In the past, several attempts have been made in order to satisfy this demand. E.g. the device as disclosed in US2597565A relates to a solution for mounting a flashlight to a rifle, document US4989358A teaches how to prolong a handgun' s butt so as to provide it with a shoulder mount, and document US5815974A instructs how to mount a universal bipod to a firearm.

[0004] . The main drawback of these constructions is that every accessory must make use of a mounting construction specific for itself, and that is different and characteristic for each and every device.

[0005] . It follows that the number of mounts that are needed increases linearly with the number of accessories, and likewise the weight and the volume that a user must take along with the firearm in case a variety of them will be needed. [0006] . The present invention therefore sets out to solve the prior art drawbacks and, in particular, it proposes a single mounting assembly that is suitable for being employed with a plurality of accessories, and wherein the simultaneous use of all these devices does not hinder to employ the others.

[0007 ] . Furthermore, it proposes a mounting assembly suitable for being used in small-dimensioned firearms like handguns.

[0008] . Such objective is achieved through a mounting assembly according to claim 1, through a firearm assembly according to claim 14, and through of a kit according to claim 27. The dependent claims show preferred embodiments .

[0009] . The present invention will now be described in detail, with the help of the enclosed drawings, wherein: figure 1 and figures 2, 3 show respectively a perspective view and sectioned perspective views of a firearm assembly according to a possible embodiment of the present invention, wherein the firearm slide in figures 2 and 3 is positioned in different working configurations ;

- figure 4 shows the firearm assembly according to figure 1, wherein the shoulder stock and the assembly frame are separated from each other; figures 5a and 5b illustrate two different kits according to the present invention;

- figures 6a and 6b exemplify the barrel lengths of an over-standard and of a standard firearm barrel, respectively;

- figures 7a, 7b, 7c show in this order perspective views of a flashlight /laser pointer device, of a spyglass and of a bipod part of the firearm assembly of figure 1 according to further possible embodiments;

- figures 8, 9 and 10 are a view with separated parts and two sectional side views of a handgun with a closure allowing an axially recoiling barrel, according to a possible embodiment.

[0010] . With reference to the aforesaid drawings, reference numeral 1 globally indicates a mounting assembly of at least a firearm accessory 2, 4' , 4", 6, 8 to a hand-held firearm 10.

[0011]. As a non limiting example, the firearm accessory comprises a tripod or a bipod 2, a flashlight 4', a laser pointer 4", a spyglass 6, a night-vision device, an (electronic) target tracking device and/or a shoulder stock 8.

[0012] . Preferably, the mounting assembly is made from an aluminium alloy or from a light-metal alloy.

[0013] . Mounting assembly 1 comprises an assembly frame 12 suitable for being joined in a reversible manner to the firearm 10, and in particular to a firearm frame 54. As a consequence, the mounting assembly may be mounted to or disassembled from the firearm 10 as needed.

[0014] . To this purpose, an embodiment foresees that the assembly frame 12 comprises releasable blocking means 52 suitable for working between said frame 12 and the firearm frame 54, and in particular between said frame 12 and a support wall 112 of firearm frame 54, so as to create a relative joining.

[0015] . According to the embodiment shown in figures 2 and 3, the releasable blocking means 52 comprise a working member 68 that is resiliently biased against the firearm frame 54, optionally against the support wall 112. Preferably, the working member 68 is manually operable for disengaging it from the firearm frame 54, and hence for separating the mounting assembly 1 from the firearm 10. E.g. the releasable blocking means 52 comprise a first actuating portion 70, suitable for being maneuvered by a user and connected to the working member 68 to provoke the above disengagement.

[0016] . According to an embodiment, the first actuating portion 70 and the working member 68 are hinged to the assembly frame 12, the rotation axis X being for example in an intermediate position between said portion 70 and said member 68. Furthermore, according to a further development, at least the first actuating portion 70 is positioned in a lowered seat 80 of frame 12 so as to avoid accidental operation.

[0017] . Preferably, the assembly frame 12 comprises an outer shaft 26 and an inner shaft 28, the latter being mounted coaxially to the outer shaft 26 and linked to this shaft 26 through at least a radial rib 30, 32', 32".

[0018]. In other words, the radial rib 30, 32', 32" keeps these shafts 26, 28 in a distanced and fixed position in relation to each other; this way, at least a tubular space 14 is advantageously enclosed by these shafts .

[0019] . According to an advantageous embodiment, both the inner 28 and the outer 26 shaft are proximally and distally open, i.e. they possess access openings 72, 74 to their inner compartments 24, 76.

[0020] . Within this patent specification, the term "distal" will be used to indicate the components positioned towards the firearm muzzle 78, while the wording "proximal" will be taken to mean the components of the assembly positioned away from said muzzle 78, i.e. near or towards a shoulder stock 8.

[0021] . According to the variant shown in figure 4, the assembly frame 12 comprises a couple of diametrically opposite first radial ribs 32' , 32", and preferably also a second radial rib 30 that is angularly equidistant from the first radial ribs 32', 32". E.g. the first radial ribs 32' , 32" extend from lateral walls 82' , 82" of the outer shaft 26, while the second rib 30 connects the inner shaft 28 with an upper wall 84 extending between the lateral walls 82', 82".

[0022]. In relation to the ribs 30, 32', 32" length, optionally the extension of any of them is substantially coincident with the distance end to end of the inner shaft 28.

[0023] . According to the embodiment depicted in the drawings, the outer shaft 26 has a generically square or rectangular cross section, e.g. with rounded corners, while the inner shaft has a round-shaped cross-section.

[0024] . Preferably, the longitudinal extension of the inner shaft 28 is smaller than that of the outer shaft 26. In other words, according to a preferred embodiment, the inner shaft 28 is axially completely contained in the outer shaft 26.

[0025] . In the present description the term "longitudinal" will be assumed to mean a direction substantially parallel to a barrel axis Z of said firearm 10. Also the wording "coaxial" will be referred to that same axis Z. [0026] . The assembly frame 12 delimits one or more accessory seatings 14, 16, 18', 18", 20 for releasable connection of the firearm accessory 2, 4', 4", 6, 8, or of the plurality thereof, to said assembly frame 12.

[0027] . In other words, mounting assembly 1 allows a single or a variety of different accessories to be stably mounted to the firearm in a loss-proof manner, preferably so as to avoid functioning interferences between them.

[0028] . Optionally, the assembly frame 12 defines a battery compartment (not shown) suitable for housing a battery, e.g. rechargeable, suitable for feeding one or more the accessories 4' , 4", 6. According to this embodiment, the assembly 1 further comprises electrical connection means extending between the battery and the accessory 4', 4", 6 for leading electrical power to the latter. E.g. an access opening to said compartment is accessible from the outer surface of the assembly frame 12. Preferably, the battery is a spare battery to be used in case of need.

[0029] . According to a preferred embodiment, the assembly frame 12 at least partially surmounts the firearm barrel 22 so as to rest thereon. Even more preferably, the assembly frame 12 delimits a longitudinal socket 24 for at least partially housing the firearm barrel 22, advantageously in a slidable manner. [0030] . According to a further preferred embodiment, the inner shaft 28 internally defines the longitudinal socket 24. As a consequence, the inner shaft 28 according to this embodiment is coaxial to the firearm barrel 22,

[0031] . This way, a prevailing portion of the firearm barrel 22 is advantageously contained in the longitudinal socket and, optionally, a proximal mouth portion of said inner shaft 28 makes an annular abutment surface 82 for the firearm frame 54 or for a firearm slide 62.

[0032]. According to an embodiment, the outer shaft 26 is crossed by at least one shaft slot 34 or hole to allow cooling of the inner shaft 28 and/or of the firearm barrel 22. In other words, the shaft slot 34 allows at least inner compartment 76 to communicate with the outside environment, in particular for heat dissipation.

[0033] . In a variant of the above assembly 1, the assembly frame 12 delimits a first accessory seating 14, which opens distally (e.g. through a distal aperture 88), for at least partially housing a flashlight 4' and/or a laser pointer 4". This seating 14 is preferably laterally closed by the inner 28 and by the outer 26 shaft.

[0034] . With reference to figures 3 and 7a, the flashlight 4' and/or laser pointer 4" shape-couple within the first accessory seating 14. For example, the external outline of a casing 86 enclosing these accessories (4' and/or 4") is complementary to the internal surface of the outer shaft 26 and to the external surface of the inner shaft 28. As a consequence, the casing 86 may be slidingly introduced in the first accessory seating 14 from the distal aperture 88, so that the light source/s 90, 92 is/are directed distally outwards.

[0035] . According to a further variant, the assembly frame 12 delimits one or more of a second accessory seating 16 for engaging a bipod 2, a third accessory seating 18', 18" for joining a shoulder stock 8 and/or a fourth accessory seating 20 for connecting a spyglass 6.

[0036]. Preferably, these accessory seatings 16, 18', 18", 20 are non coincident and advantageously distributed around the outer shaft 26 so as to face in different spatial directions.

[0037]. Advantageously, said seatings 16, 18', 18", 20 independently comprise a lower rail 36, at least a lateral rail 38 and/or an upper rail 50 respectively provided for sliding support of the bipod 2, of the shoulder stock 8 and/or of the spyglass 6.

[0038] . According to different embodiments, the lower rail 36 is positioned at a lower wall 94 of the assembly frame 12 (and in particular of the outer shaft 26), the lateral rail(s) 38 are placed at the lateral wall(s) 82', 82" and/or the upper rail 50 is located at the upper wall 84, so that the spyglass 6 (e.g. shown in figure 7b) is connected on top of the assembly frame 12.

[0039] . The rail 36, 38, 50, or the plurality thereof, is preferably rack-shaped, e.g. for fine adjustment of the accessory 2, 4', 4", 6, 8 position. In fact, the pitch between the rack teeth 96 may be selected so as to obtain any desired accessory setting. Advantageously, the rail 36, 38, 50 extends along and projects outwards from the assembly frame 12, and optionally from the outer shaft 26.

[0040] . The present invention further relates to a firearm assembly 60, e.g. a gun assembly, comprising a hand-held firearm 10 and a mounting assembly 1, according to any of the previous embodiments, connected to said firearm 10.

[0041] . Preferably, the firearm 10 is an automatic or semi-automatic handgun having a firearm frame 10, suitable for being gripped and supporting a firearm barrel 22.

[0042] . Even more preferably, the mounting assembly 1 is stably supported by the firearm barrel 22, e.g. in all the working configurations of the latter.

[0043] . According to different embodiments, the firearm barrel 22 is firmly joined to the firearm frame 54 or is suitable for axially recoiling in relation to the firearm frame 54. Advantageously, in both embodiments, the firearm barrel 22 is (slidingly) supported by the support wall 112.

[0044 ] . In the context of the present invention, the term "axially recoiling" is referred to a recoiling action wherein, at each phase of firing, the barrel remains straight and in line, and any inclination thereof is avoided.

[0045] . With reference to figures 8-10, a possible technical solution for obtaining this axial recoiling is e.g. disclosed in P C T / I B 2011 / 054123 of the same applicant, whose essential features are reported herein after .

[0046] . In an initial phase (forward configuration) , a cartridge (not shown) is found to be inserted in a firing chamber 110 proximally delimited by the firearm barrel 22 and the relative position of the firearm frame 54, the firearm barrel 22 and the firearm slide 62 is as shown in figure 10: the distal end 62' of the firearm slide 62 is substantially aligned with the free portion of a support wall 112 and is kept in such position by the action of a recovery spring 114, sliding in a seat delimited between the firearm barrel 22 and the firearm frame 54, which is in an extended configuration.

[0047 ] . The firearm barrel 22 and the firearm slide 62 are joined by a locking device 116 in that the latter, adjacent to the barrel axis Z, occupies the seat 118 housing the firearm barrel and stops the firearm slide 62 by means of the geometric coupling of locking ridges 120, 122 provided on the locking device 116 and locking seats 124, 126 of the firearm slide 62.

[0048] . In addition, initially, a movement lug 128 integral with the firearm frame 54 is positioned at a proximal vertex of a sliding slot 130 of the locking device 116.

[0049] . When the trigger 132 is pulled, the firing device moves the firing pin 134 towards the firing chamber 110, so as to strike the fuse of the cartridge therein inserted and to cause the explosion. By way of reaction a bullet comes out distally from the muzzle 78, and the firearm barrel-locking device-slide group recoil for a certain distance. As may be seen, for example, in figure 9, the distal end of the slide 62' is rearwardly moved in relation to the free portion of the support wall 112, and the firearm barrel 22 too is proximally shifted in relation to the firearm frame 54.

[0050] . As a result of the combined movement of longitudinal translation of the firearm barrel and the sliding of the movement lug 128 along the sliding slot 130, the locking device 116 is distanced radially from the barrel axis Z. During this movement (and also during the opposite movement) abutment protrusions 138, 140 extending radially (in relation to axis Z) from the outer surface of the firearm barrel influence and guide the locking device 116.

[0051] . When such lug 128 reaches the distal vertex of the sliding slot 130, the locking ridges 120, 122 have come out of the locking seats 124, 126 and have aligned with longitudinal riflings 134, 136 of the firearm slide 62. This way, the firearm slide is released from the firearm barrel, which has reached an end stop. The orientation of the firing chamber 110 rather has remained substantially coincident with the barrel axis Z, in that the distancing from such axis relates solely to the locking device 116.

[0052] . Subsequently, given that the pressure inside the firing chamber is sufficiently high to overcome the recall force of the recovery spring 114, the firearm slide continues its rearward movement starting aperture of the firing chamber (rearward configuration) . During such backward movement, the locking ridges 120, 122 slide along the longitudinal riflings 134, 136 and therefore act as translation guides.

[0053] . Lastly, when the pressure in the firing chamber falls below a predefined value such as to be overcome by the recall force of the recovery spring 114, which is compressed, the firearm slide 62 inverts direction, pointing itself distally, restoring the configuration of the firearm barrel and of the locking device existing in the forward configuration (figure 10) . In such configuration, the gun is ready for a new firing cycle.

[0054] . According to further embodiments allowing "axial recoiling", the firearm barrel recoils thanks to a bolt in two parts with interposed rollers, such as the arrangement used in the submachine gun Heckler&Koch MP5, or by virtue of a roto-translating barrel locking system, such as the device used in the handgun Beretta 8000. As a consequence, axial recoiling could also involve rotation of the firearm barrel.

[0055]. Preferably, the firearm barrel 22 is over- standard, i.e. it comprises a firearm barrel 22 having a protruding portion 56 projecting distally beyond the firearm frame 54.

[0056] . As already mentioned herein before, the firearm barrel 22 preferably provides a sufficiently wide contact surface 142 with the mounting assembly 1 so as to firmly bear the latter in all the working configurations of said barrel 22.

[0057]. In other words, for firearms having a non- recoiling barrel, the firearm barrel must project outside the firearm frame so as to furnish the contact surface 142 for bearing the mounting assembly 1. For the embodiments with an axially recoiling barrel, a sufficient contact surface 142 must preferably be assured in all the working configurations of the firearm.

[0058] . As a consequence, in the latter of these embodiments, the protruding portion 56 delimiting the contact surface 142 must be available also and in particular in the rearward configuration. In other words, the protruding portion 56 must be present during all the backward recoiling movement of the firearm barrel.

[0059]. A firearm barrel may be considered over- standard if the protruding portion 56 develops distally for at least 0.1% or more the overall length of the firearm frame. As a non limiting example, a firearm barrel is over-standard if it projects for more than 5- 10%, preferably more than 30-40%, advantageously more that 50% the length of the firearm frame taken in a direction parallel to the barrel axis Z. According to the embodiments shown in the figures, the firearm barrel projects for about 70-95%, and preferably for 80-90% the lengthwise measurement of the firearm frame.

[0060] . According to an embodiment, the protruding portion 56 is a connectable extension 66 suitable for being coupled to the firearm barrel, preferably to a standard-type firearm barrel 58. Of course, the coupling between the above extension 66 and a distal end portion 58' of the standard barrel may be performed by screwing (as shown in figure 5b) of with a bayonet-type connection.

[0061] . Preferably, the firearm barrel 22 and the protruding portion 56 are one-pieced, and are preferably made so as to replace a standard-type firearm barrel 58.

[0062] . In other words, this embodiment provides that the one-pieced firearm barrel 22 and protruding portion

56 are a spare part for a firearm with a standard-type barrel .

[0063] . According to a further embodiment, the assembly frame 12, and optionally the outer shaft 26, at least partially house a firearm slide 62 in a reciprocating movable manner.

[0064]. E.g. with reference to figures 2 and 3 it is possible to see that the slide is movable between the forward configuration and the rearward configuration, and that the assembly frame does not hinder the slide movement between these configurations.

[0065] . In other words, a specific embodiment foresees that the inner 28 and the outer 26 shaft are radially distanced so that the former at least partially houses the firearm barrel 22, and the latter at least partially encloses the firearm slide 62 so as to allow a translation of the latter.

[0066] . Preferably, firearm assembly 60 comprises at least one of a bipod 2, a flashlight 4' , a laser pointer 4", a shoulder stock 8 and/or a spyglass 6 connected to the assembly frame 12.

[0067] . As mentioned herein before, these accessories are preferably engaged in the second accessory seating 16, in the first accessory seating 14, in the third accessory seating 18', 18" and/or in the fourth accessory seating 20, respectively and independently from each other .

[0068] . According to an embodiment the bipod is fixed, i.e. its legs are in an unchanging reciprocal position. Preferably, at least a bipod leg 98' , 98" is telescopic and/or foldable; even more preferably, both legs 98', 98" possess these telescoping and/or folding features. For example as shown in figure 7c, at least one leg 98' is rotatably mounted (around an axis M, preferably parallel to barrel axis Z) on a bipod body 144 so as to be movable from the represented use configuration, wherein the legs are spaced apart, to a (non depicted) non-use configuration, wherein the legs are adjacent to each other or, in any case, wherein the overall leg encumbrance is reduced. [0069] . According to an alternative variant, the shoulder stock 8 extends proximally from the assembly frame 12 and comprises at least a first coupling element 40' , 40" to the lateral rail 38 so as to be movable along said rail 38. E.g. the coupling elements have a dovetail- shaped engagement with the lateral rail 38 and comprise blocking means 100 for maintaining a preset longitudinal position .

[0070] . According to the embodiment shown in the figures, the blocking means 100 comprise a second actuating portion 102, manually operable, suitable for reversibly moving an engagement tooth 104 in abutment and away from the lateral rail 38, preferably in the spaces 106 defined between adjacent rack teeth 96. E.g. the actuating portion 102 is rotatable in relation to the respective coupling element 40', 40".

[0071] . According to further variants, besides coupling between the lateral rail 38 and the shoulder stock 8, also connection between the lower rail 36 and the bipod 2 and/or between the spyglass 6 and the upper rail 50 may be dovetail-shaped.

[0072] . Preferably, the shoulder stock 8 comprises a couple of opposite first coupling elements 40', 40" that are transversally distanced so as to span the assembly frame 12. [0073] . Advantageously, the shoulder stock 8 comprises at least a stiffening portion 42 that joins opposite sides 44' , 44" of said stock 8 for mechanical strengthening .

[0074 ] . According to the embodiments shown in the figures, the shoulder stock 8 comprises a first 106' and a second 106" distancing element (e.g. in the form of bars or profiles) mechanically connecting the stiffening portion 42 with the coupling elements 40', 40". According to a further embodiment, proximally to the stiffening portion 42 and joined thereto, the stock 8 comprises an ergonomic structure 108 suitable for abutting against a user's shoulder.

[0075] . According to an advantageous embodiment, the stiffening portion 42 has an inner concave surface 46 suitable for making an aiming route 48 for a user. Preferably, the inner concave surface 46 faces downwards, when the firearm assembly is correctly shouldered.

[0076] . The present invention relates also to a kit 64' , 64" comprising a mounting assembly 1 according to any of the previous embodiments, and an over-standard firearm barrel 22 or a connectable extension 66 of a (standard-type) firearm barrel 58 suitable for being mounted on the firearm 10.

[0077 ] . Optionally, the kit 64' , 64" comprises at least a firearm accessory 2, 4', 4", 6, 8 according to any of the previous configurations.

[0078] . Innovatively, the present invention allows the use of a single mounting assembly for mounting a plurality of accessories, wherein the simultaneous use of all these devices does not hinder to employ the others.

[0079] . Advantageously, the present mounting assembly is suitable for being used both in rifles, in machine- guns and in small-dimensioned firearms like handguns.

[0080] . Advantageously, the present firearm assembly is suitable for maintaining a reliable firing accuracy, even with extremely high magnification ratios of the aiming structures. This is also due to the reduced production tolerances according to which the assembly frame is manufactured. As a consequence, the firearm assembly according to the present invention guarantees an unmatched ballistic accuracy.

[0081] . Advantageously, the present firearm assembly obtains a higher shooting power at a same calibre; in fact the thrust action of the gases on the bullet lasts longer than in traditional assemblies, so that a higher precision is herewith obtained.

[0082] . Advantageously, the present mounting assembly is suitable for being removed rapidly from the firearm, so that the accessories may all be disassembled at once. [0083] . Advantageously, the mounting assembly according to the present invention allows a rapid heat dissipation from the barrel, in particular due to the combined transfer modality foreseen a metal conduction and a solid-fluid heat transfer.

[0084 ] . A person skilled in the art may make variations to the embodiments of the assemblies and kit described above or replace elements with others functionally equivalent so as to satisfy specific requirements.

[0085] . Such variations also fall within the scope of protection as defined by the following claims.

[0086] . Moreover, each of the embodiments described as belonging to a possible embodiment may be performed independently of the other variants described.
