专利说明:

[001] The present invention refers to a firearm. Specifically, the firearm to which the present invention refers presents a new specific structure, to facilitate its assembly and disassembly operations.
[002] In particular, the firearm to which the present invention relates is a semi-automatic firearm, preferably a revolver.
[003] In the prior art, firearms comprising pre-defined locking systems, capable of holding the firearm in a predefined position, are known, and specifically, in fact, the systems are known to be part of firearm, whose objective is to keep the moving parts connected to the fixed parts, in other words, the systems are known to be able to keep the cursor operationally connected to the stock.
[004] These systems must therefore satisfy the requirements imposed on a firearm in a ready-to-fire configuration, that is, eliminate the risk of accidental disassembly, for example following a shot or a fall, and the requirements for carrying out firearm disassembly operations, which must, in fact, occur without risk to the user performing these operations.
[005] However, of the two needs mentioned above, the prior technique has focused on the first problem, sacrificing in part the second.
[006] Said systems usually comprise at least one transverse element, for example a breech, which is inserted along an axis transverse to the longitudinal axis, axis along which the cursor extends, is suitable to act together with it, to keep it connected to the stock.
[007] In the prior art, the firearm assembly and disassembly operations are, therefore, particularly complex, requiring, on the part of the user who performs them, particular care and skill.
[008] Currently known systems are usually structured in such a way that, in disassembly operations and unlike in firearm assembly operations, the user must use both hands in perfect synchrony, keeping the cursor in a position backwards, overcoming the force of the recoil pin acting on it, and, at that moment, pulling the breech to a predefined position, allowing extraction in a forward direction of the slide, releasing it from the stock.
[009] In some embodiments, said systems also comprise other special components, suitable to lock the cursor in said backward position while operations on the breech are being made.
[010] The disassembly operations are, therefore, in addition to complex, particularly dangerous for the user due to the fact that, in the case of lack of tightening of the cursor in the backward position, it may come loose forward, moved by the spring, and thereby hitting it.
[011] The purpose of the present invention is the production of a new firearm, in which the assembly and disassembly operations are simplified and less risky than those made in firearms comprising the systems of the prior art, the The firearm to which the present invention relates achieves these objectives by keeping the cursor locked on the stock, in a completely secure manner.
[012] This end is achieved by a firearm according to claim 1. Other advantages and characteristics of the firearm, according to the present invention, will be evident according to the dependent claims.
[013] Specifically, the firearm to which the present invention refers proved to have a new and innovative structure, and, in particular, a new breech, in order to make the assembly and disassembly operations simpler and safer. than typical prior art devices, while keeping the moving parts fully locked with the fixed parts at the same time once they have been assembled.

[015] With reference to the attached drawings, the reference number 1 generally indicates a firearm in its entirety, preferably, said firearm is a semi-automatic revolver.
[016] The firearm 1 comprises a stock 2 and a slider 3, preferably the slider 3 extends along a longitudinal axis X - X and is suitable for translation along said axis, preferably the slider 3 comprises a pipe 31.
[017] In a ready-to-fire firearm configuration, the slider 3 is preferably coupled with the stock 2, the slider 3 comprises a spring holder 35 and a return spring 30, positioned in said spring holder 35, said return spring 30 acting on spring holder 35, and thus suitable for keeping the slider 3 in a forward position and the firearm 1 ready for firing, i.e. in a position in which the cycle shooting is ready to start.
[018] The stock 2 is furthermore suitable for supporting a triggering mechanism 600, preferably comprising a trigger and various couplings, or generic transmission means for transmitting the movement of said trigger to the relative means provided for the trigger operation.
[019] Preferably, said support chassis 10 is suitable for conducting said reciprocal coupling between stock 2 and slider 3.
[020] Furthermore, according to a preferred embodiment, said support frame 10 is housed, at least partially, in stock 2. Preferably, in turn, said support frame 10 extends along the longitudinal axis X - X.
[021] In a preferred embodiment, the firearm 1 further comprises a breech 50, which extends along a transverse axis Y - Y, transverse to the longitudinal axis X - X, according to a preferred embodiment, said axes extending in directions perpendicular to each other.
[022] Furthermore, preferably, the breech 50 is translatable and rotatable along said transverse axis Y - Y.
[023] In a preferred embodiment, the bolt 50 is coupleable with the stock 2 and/or with said support chassis 10, preferably, in addition, as illustrated above, depending on the embodiments, the translation and rotation of the bolt 50 are substantially associated with the type of coupling thereof with the firearm 1, and in particular with the stock 2 or with the chassis 10, depending on the embodiment.
[024] Preferably, the bolt 50 is suitable to assume a locking position, in which the slider 3 is locked onto the chassis 2, preferably by means of the support chassis 10, in such a way that it is free to perform the specific firing armature movements, and a released position in which the slider 3 is detachable from the stock 2, through dedicated operations performed by the user.
[025] In other words, once inserted in the firearm 1, the bolt 50 has the purpose of joining the stock 2, in particular through the chassis 10, to the slider 3, which is coupled with the spring holder 35, stock 2 and slide 3 are thus kept in a ready-to-fire position.
[026] According to a preferred embodiment, the bolt 50 comprises a spring holder seat 500; in said spring holder seat 500, when the yoke 50 is placed in the locked position, it acts in conjunction with the spring holder 35, specifically with a coupling end 350 of the spring holder 35. The spring holder 35, specifically, its coupling end 350, which acts in conjunction with the bolt 50, is loaded by the force of spring 30.
[027] The other end of the spring holder 35, in fact, is coupled with the front end of the slider 3, in particular near the muzzle of the firearm.
[028] According to a preferred embodiment, the spring holder seat 500 comprises several surfaces, having a series of well-defined purposes: a support surface 501, on which said coupling end 500 engages, when the yoke 50 is in the locked position; and a translation surface 502, suitable to allow translation of the yoke 50, acting in conjunction with the coupling end 350.
[029] Preferably, in addition, the spring holder seat 500 further comprises a rotation surface 503, suitable to allow the rotation of the bolt 50, acting in conjunction with the coupling end 350.
[030] According to a preferred embodiment, the support surface 501 comprises a plane, in which said coupling end 350 is, when the bolt 50 is in the locked position. According to a preferred embodiment, the support surface 501 is composed of a single plane.
[031] Preferably, the support surface 501 substantially extends along the transverse axis Y - Y; moreover, preferably, support surface 501 extends longitudinally over a yoke section 50; preferably, the support surface 501 is a cavity within the yoke 50.
[032] Other embodiments are provided in which the reciprocal coupling between the coupling end 350 and the support surface 501 is improved as a result of the geometries of the two components: for example, an embodiment in which the support surface 501 it is concave and acts in conjunction with a 350 convex coupling end.
[033] Specifically, the support surface 501 is laterally delimited on one side by said translation surface 502, and, on the other side, by a substantially perpendicular lateral surface 511.
[034] According to a preferred embodiment, the support surface 501 has substantially complementary dimensions with respect to the coupling end 350.
[035] The translation of the bolt 50 is thus possible due to the fact that the coupling end 350 itself meets laterally with the translation surface 502, which, due to its inclination, provides the relative movement between the bolt 50 and the coupling end 350.
[036] Said translation surface 502 is, in fact, preferably positioned adjacent to the support surface 501 and is inclined relative to it along the transverse axis Y - Y.
[037] In other words, the translation surface 502 is angled or arcuate, so that when the yoke 50 is moved along the transverse axis Y - Y, the coupling end 350 is allowed to move away from the support surface. 501. During this movement, spring 30 is further compressed.
[038] As mentioned, the spring holder seat 500 further comprises a rotation surface 503, suitable to allow the rotation of the yoke 50, when acting in conjunction with the coupling end 350, said rotation surface 503 is adjacent to the support surface 501 and the translation surface 502, thereby extending longitudinally along the transverse axis Y - Y. Said rotating surface 503 is furthermore inclined relative to both said surfaces , along the longitudinal axis X - X.
[039] In other words, the rotation surface 503 is angled or arcuate, so that when it is coupled by the coupling end 350, rotation about the Y-Y transverse axis of the yoke 50 is allowed and forced.
[040] According to a preferred embodiment, the bolt 50 extends along the transverse axis Y - Y, so as to protrude on at least one side of the firearm 1; preferably, the breech 50 extends to protrude on both sides of the firearm 1.
[041] Furthermore, according to a preferred embodiment, the bolt 50 comprises a translation part 51, suitable to be actuated by the user, to move the bolt 50 along the transverse axis Y - Y, and a part of rotation 52, suitable for user actuation, to move the yoke 50 rotationally about the transverse axis Y - Y.
[042] Preferably, the translation part 51 is suitable to be pushed by the user, in order to move the bolt 50 in translation. In other embodiments, the translation portion 51 is suitable for being pushed by the user in order to move the bolt 50 in translation.
[043] According to a preferred embodiment, the rotating part 52 extends substantially radially with respect to the transverse axis Y - Y, so as to allow it to be moved in a simple and intuitive manner by the user.
[044] According to a preferred embodiment, the translating part 51 is opposite the rotating part 52, so that the translating part 51 protrudes from one side of the firearm 1, while the rotating part 52 is projects across firearm 1.
[045] Preferably, the rotation part 52 projects from the side of the firearm 1, when the breech 50, starting from the locked position, is translated along the transverse axis Y - Y, after operation of the translation part 51, for example, by pushing it. Preferably, Preferably, therefore, when the bolt 50 is in the locked position, the rotating portion 52 is "smoothed" to the side of the firearm 1, immersed therein, thereby preventing lateral problems.
[046] Preferably, in the passage from the locked to the released position, the translation of the breech 50 is possible before its rotation; on the contrary, when moving from the released to the locked position, the rotation of the yoke 50 occurs before its translation. In other words, the user is prevented from performing the rotation of the yoke 50 before it has been translated to a predefined position. Preferably, to move the bolt 50 to the released position of the firearm 1, starting from the locked position, the bolt 50 must be translated, for example, by pushing, to a predefined position, in which, in this way, the user can rotate it and finally position it in a released position.
[047] On the contrary, in the step of assembling the locked position of the firearm 1, the insertion of the breech 50 provides a rotation step, before a translation step.
[048] According to a preferred embodiment, the support chassis 10 then extends substantially to the sides of the firearm 1.
[049] Preferably, in fact, the chassis 10 comprises a first wing 11, positioned substantially on the side of the firearm 1, said first wing 11 is traversable by the breech 50, by a first hole 101. When the bolt 50 is inserted into the firearm 1, thus, through the first hole 101, the coupling between the bolt 50 and the stock 2 is created.
[050] According to some embodiments, the support chassis 10 comprises two wings, said first wing 11 and a second wing 12; the two wings are positioned substantially on the sides of firearm 1, opposite each other.
[051] According to said embodiments, therefore, the chassis 10 extends along the longitudinal axis X - X, with a substantially C- or U-shaped cross section. Preferably, the two wings 11 and 12 are parallel between themselves.
[052] Preferably, the breech 50 crosses both the first wing 11, through the first hole 101, and the second wing 12, through a second hole 102.
[053] Preferably, the interaction of chassis 10 and breech 50 directly influences the movement of the latter. Specifically, in fact, the respective geometries of the bolt 50 and the chassis 10, in particular the first hole 101 and/or the second hole 102, are designed so that some movements are allowed or prevented only under certain circumstances, in other words only in some predefined positions, between the breech 50 and the chassis 10.
[054] According to a preferred embodiment, in fact, the breech 50 has a flattened part 55 along its length, i.e. a flat surface, suitable to act in conjunction with the chassis 10; preferably, the first hole 101 and/or the second hole 102 have an irregular geometry, for example not axially symmetrical, comprising an anti-rotation part 150, suitable for interacting with said flat part 55.
[055] The interaction between the flat part 55 and the anti-rotation part 150 acts to prevent the rotation of the yoke 50, when it is placed in a predefined position, along the transversal axis Y - Y; in other words, when the breech is positioned so that the flat portion 55 and the anti-rotation portion 150 of the bore face each other.
[056] Preferably, the shape of the first hole 101 and/or the second hole 102, specifically the one or those interacting with the flat part 55, is irregular, i.e. a non-circular shape, so that the rotation of any axial symmetrical (breech) element is impeded within it(s).
[057] The bolt 50, thus, preferably has, at least in its part suitable for interaction with the chassis 10, an irregular geometry, while the hole, which acts in conjunction with it, preferably has a shape complement to it.
[058] This geometry of the components makes the yoke 50 insertable in the firearm 1 and the chassis 10, in a unique position, in which the yoke 50 is suitable to pass through the first hole or the second hole 101 or 102 of a geometry. irregular.
[059] According to a preferred embodiment, the breech further comprises a cavity 58, which extends concentrically with respect to the transverse axis Y - Y, on the surface of the breech 50.
[060] In particular, cavity 58 has the specific purpose of allowing the rotation of the yoke 50 around the transverse axis Y - Y, in that it is placed in a predefined position along said axis, so as to correspond radially to the first or second hole 101 or 102 of an irregular geometry. In the embodiment with the holes having an irregular geometry, the yoke 50 comprises two cavities 58.
[061] In other words, the bolt 50 is suitable to be placed in a pre-defined position along the Y - Y transverse axis, where the cavity 58 itself faces the first or second hole 101 or 102, and, specifically, its anti-rotation part 150; due to the presence of the cavity 50, there is no coupling along the axis of translation between the yoke 50 and the chassis 10, the anti-rotation part 150 itself is, in fact, suitable to be placed inside the cavity 58, so as to allow rotation of the bolt 50 about the transverse Y - Y axis.
[062] The cavity 58 thus has a width substantially equal to or greater than the width of the wing of the chassis 10, which acts in conjunction with it, so that it is able to house it, when the breech rotation occurs preferably a width substantially equal to the width of the anti-rotation part 150 acting in conjunction with it.
[063] Preferably, therefore, when the chassis 10 is housed in said cavity 58, the yoke 50 is prevented from translating along the transverse axis Y - Y; the breech 50 is, in fact, locked in the chassis 10, in fact, this is housed in the cavity 58, between the side surfaces 581, with which it is defined. Said lateral surfaces 581 interact with the chassis 10, obstructing or preventing the translation of the yoke 50 along the transversal axis Y - Y.
[064] According to a preferred embodiment, the cavity 58 extends over a predefined arc of circumference, specifically suitable to allow a maximum rotation of the breech around the transversal axis Y - Y of 90°.
[065] In other words, the cavity 58 comprises a limiting abutment surface 585, substantially perpendicular to the flat part 55, suitable for meeting in rotation the anti-rotation part 150, to interrupt the rotation course of the yoke 50.
[066] Preferably, the flat part 55 and/or the cavity 58 are then positioned in the translation part 51.
[067] According to the non-limiting example shown in the attached drawings, the chassis comprises two wings 11 and 12; preferably, breech 50 is thereby suitable for traversing both wings through first hole 101 and second hole 102; the translation part 51 is opposite the rotating part 52; the translation part 51 is preferably suitable to be operated by means of a push by the user.
[068] In the locked position, the bolt 50, in said embodiment, thus presents the translation part 51 projecting on one side of the firearm 1, while the rotation part is "close" to the other side of firearm 1; starting from said position, the bolt 50 is then translated, and the rotating part 52 projects from the side of the firearm 1.
[069] Preferably, the breech 50 is inserted in the firearm 1, meeting, first, the first wing 101 and, subsequently, the second wing 102 of the chassis 10; Preferably, the first hole 101 is of a circular shape, while the second hole 102 is of an irregular geometry to interact, as illustrated with the locked position 55 and the cavity 58, positioned after the translation part 51.
[070] The steps of assembly and disassembly of firearm 1 will be illustrated below with reference to the attached drawings. It will thus be clear how the structure and the different types of coupling of the various components, described above, provide the advantages in disassembling the firearm 1 and assembling it.
[071] The assembly and disassembly operations are to be understood as meaning the coupling and decoupling of the slider 3 on / of the stock 2.
[072] Starting from a position of a firearm ready to fire, in which the cursor 3 is positioned on the stock 2 and the breech is in the locked position, reciprocally blocking the two components.
[073] In said locked position, the spring holder 35 in the yoke 35, in particular, the coupling end 350 is housed in the spring holder seat 500 and the spring 30 is loaded so as to keep the slide 3 in a forward position. Spring carrier seat 500 is thereby positioned in a position substantially perpendicular to the longitudinal axis X - X, along the transverse axis Y - Y.
[074] The user, by operation of the translation part 51, moves the bolt 50 in translation, the spring holder 35 is held in position along the longitudinal axis X - X by two centering elements 22 included in the stock; thereby, coupling end 350 exits support surface 501 and begins to interact with translation surface 502. Due to the slope of translation surface 502, coupling end 350 can translate along the longitudinal axis X - X, moving in a longitudinal direction, preferably perpendicular to the Y - Y transverse axis.
[075] In this just-described translated position, the yoke 50 is thereby positioned in such a way that the cavity 58 itself faces radially towards the anti-rotation portion 150 of the chassis 10.
[076] The bolt 50 is thus then free to be rotated, that is, the user, acting on the rotation part 52 then accessible, since it is in projection as a consequence of the anterior translation of the bolt 50, can rotating it along the length of the cavity 58, substantially by approximately 90°, for example, until the anti-rotation portion 150 touches the boundary abutment surface 585.
[077] Preferably, the barrel 31 comprises a dedicated recess 39; by rotation of the yoke 50, it moves the coupling end 350 towards said recess 39, preferably upwards, until the coupling end 350 acts directly on said recess 38 and no longer on the yoke 50.
[078] In this position, the bolt 50 thereby prevents the support surface 501 in a new position perpendicular to the previous one, that is, in a position substantially parallel to the plane that contains both the longitudinal axis X - X and the Y - Y transverse axis.
[079] This position of the breech 50 is thus the released position; the slider 3 and in particular the barrel 31, when moved, no longer encounter an obstacle and are thus free to be extracted in a forward direction and removed from the stock 2; in other words, the spring holder seat 500, positioned upwards, provides a suitable area to allow passage during the extraction of the slide 3, and in particular the barrel 31, for example, allowing the passage of specific elements of the barrel firing mechanism 31; preferably, said elements of the firing mechanism comprise a barrel disconnecting tooth 311.
[080] The firearm 1 is thus disassembled, the stock 2 and the slide 3 are mutually released.
[081] With regard to the mounting of the slider 3 on the stock 2, it should be noted that before the mounting operations, there is a stock 2 preparation operation, in which the bolt 50 is inserted into it. The insert operation of the breech 50 is only possible if it is inserted as transverse to the hole, with an irregular geometry in a specific insertion position. In said insertion position, the yoke 50 is translatable along the Y-Y transverse axis to a predefined position, in which the cavity 58 is radially aligned with the anti-rotation part 150. The yoke 50 is thus rotatable, generally by 90°, until it is placed in the released position.
[082] The bolt 50 is then positioned in the released position, in which the support surface 501 extends substantially parallel to the plane containing the longitudinal axis X - X and the transverse axis Y - Y, in other words, the seat of spring holder 500 is positioned upwards.
[083] With the bolt 50 in said position, the slide 3, with the barrel 31 and the spring holder seat 35, is free to be moved along the longitudinal axis X - X, insertable in the stock 2.
[084] The slider 3 comprises the spring holder seat 35 and the barrel 31, and by insertion into the slider 3, along the longitudinal axis X - X, the spring holder seat 35 meets the yoke 50; in particular, coupling end 350 contacts yoke 50 on rotating surface 503; the inclination of the rotation surface 503 causes the coupling end 350, loaded by the spring 30, to apply a force to the yoke 50; this force, applied on the inclined plane, sets the yoke 50 in rotation about the transverse axis Y - Y.
[085] The bolt 50 is thereby then rotated and the coupling end 350, loaded by the spring 30, contacts the translation surface 502; the translation surface being inclined, the force exerted by coupling end 350 thereon causes the yoke to translate along the Y - Y transverse axis; the yoke thereby translates until the coupling end 350 itself is housed in the support surface 501.
[086] The bolt 50, in this position, is thus in the locked position. The spring holder 35 acts on the bolt 50, perpendicular to the spring holder seat 500, the bolt 50 fully discharges said forces into the stock 2, blocking it in the slider 3 by means of the barrel 31.
[087] In other words, the passage of the bolt 50, from the released position to the locked position, during the assembly steps, is automatic and does not require the user to perform any specific operation on the bolt 50.
[088] Innovatively, the firearm, to which the present invention refers, is suitable to solve the deficiencies of the prior art, by presenting an innovative component structure, suitable to satisfy the requirements of mutual locking of the slide and the bolt , but always making assembly and disassembly operations easy and safe.
[089] Advantageously, the breech comprised in the firearm, according to the invention, was designed in such a way as to interact with the various components of the firearm, including the breech and the breech, in such a way as to make firearm disassembly operations easier for the user.
[090] Advantageously, firearm disassembly operations comprise a series of steps, in a pre-defined and irreversible order, which do not require the user's particular skills, as it is differently in the case of firearm disassembly. prior art fire. Specifically, in fact, during disassembly of the firearm, the breech can only be rotated after it has been translated; furthermore, it is not necessary to act on the breech and place it, and keep it, in a particular position, eg rear, to start operations on the breech; the first assembly operations are advantageously carried out directly on the breech 50 itself.
[091] In addition, advantageously, the user's efforts for the movements of the breech are very modest due to the fact that several operations are facilitated by the presence of inclined planes.
[092] According to another advantageous aspect, the assembly operations are automatic and do not require the execution of any operation on the breech by the user, but merely the insertion of the breech in the breech.
[093] According to another advantageous aspect, the breech is insertable, along the transverse axis, in the stock, only in a single position, the insertion position, following the rotation of the breech, placed in the released position, the passage of the The released position to the locked position is automatic by the action of the coupling end, coupled by the spring, in several inclined planes, with which it acts together.
[094] Advantageously, in the mutual interactions of the stock and/or chassis and 1 yoke, due to their reciprocal shapes, the rotation of the yoke is only allowed in a predefined position at a predefined angle. Likewise, translation is also only allowed if the breech is placed in a predefined position; Advantageously, the breech remains in the breech, even when the slider is released, due to the fact that, remaining in the released position, it is retained in the stock through the interaction between the cavity and the anti-rotation part. An obvious effect obtained by this advantage is that of preventing the breech from falling out of the stock and possibly being lost when the firearm is disassembled.
[095] According to another advantageous aspect, other elements or components of the firearm are not necessary, but the components illustrated in this patent application are sufficient to allow or prevent the execution of the various operations; no anti-pull O-rings are required to lock the breech to the inside of the stock, and no special recess or groove in the stock is required to act, for example, as an end stop for the rotation of the breech.
[096] Advantageously, the various components that interact with each other, specifically, their relative parts, which are inside the firearm, benefit from its aesthetics, giving the designer more freedom, as there are no restrictions structural, to be observed on the outside. In particular, the advantage is evident, due to the automatic movement of the breech, specifically in the last stage of its assembly, that it is possible to have, if desired, a lateral surface of the stock and the firearm, close to the rotation part, without projections , which could, for example, lead to unwanted entanglement.
[097] According to another advantageous aspect, the firearm, to which the present invention refers, comprises a smaller number of components than the typical solutions of approximately, resulting in a simpler construction, as well as more economical her.
[098] A person skilled in the art may make variations on the embodiments of the firearm described above, or substitute elements for functionally equivalent ones, in order to satisfy specific requirements.
[099] For example, in other embodiments, the chassis has a shape and structure different from those described and shown.
[0100] According to some embodiments, the specific shapes of the stock of the firearm can be to replace one or more of the components of the chassis, for example, its wings or holes.
[0101] Specifically, in fact, according to another embodiment, without a chassis 10 and/or with a chassis of a shape other than that described above, the butt acts only in conjunction with the stock of the firearm. In this embodiment, the holes described above, through which the breech is housed, are made directly into the stock; holes having the shapes and characteristics described above must thereby be drilled into the stock, so as to permit or prevent specific movements of the breech. In particular, in fact, in the case where the breech does not interact with the chassis, the components mentioned above, such as the bore of an irregular geometry, comprising an anti-rotation part, are provided in the stock.
[0102] All said embodiments do not vary in any way the assembly and disassembly operations, nor the breech preparation operations before these, in accordance with the description presented above; these operations actually involve the same steps and have the same obstructions, which carry the same advantages as illustrated above.
[0103] Or again, in other embodiments, the spatial arrangement of the various components is varied, so as to have, for example, a breech that does not protrude from both sides of the firearm, but only from one side her.
[0104] These variants are also contained within the scope of protection as defined by the claims presented below.
[0105] Furthermore, all variants, described as belonging to a possible embodiment, can be promoted independently of the other variants.
