[0001] Description

[0002] Title of Invention: ERGONOMIC TRIGGER BLADE FOR SMALL ARMS (VARIANTS).

[0003] Technical field

[0004] The invention relates to the field of the weapons industry, in particular to small arms, and can be used in the design of firearms, pneumatic, mechanical and electric small arms.

[0005] Background Art

[0006] The device described in the article is known: "3 - Trigger Pull with Pistols" (by Mike C., photos by Bob McKerrell, published by https: / / canadianshooter.wordpress.com / trigger-finger / , Website https: / / canadianshooter.wordpress.com / ), comprising a lever and a fixed support which is made in a small arms, wherein the lever is connected to the fixed support, is made with the possibility of turning relative to the fixed support, and forms a kinematic pair with the fixed support, and is mounted at an angle to the axis of rotation of the lever relative to the fixed support. The known device has a number of significant disadvantages:

[0007] - The main disadvantage is that as a result of the impact of the index finger on the trigger blade, there is a torque of forces, the center of rotation of which is located in the handle of the small arms, clamped in the palm of the human finger. As a result, at the moment of firing, the weapon rotates in the palm of a person's hand and leads to displacement of the aiming point and misses the target.

[0008] A device is known:

[0009] "Mechanical release or trigger device" (patent US6957644B2 from 26.11.2003, cl. F41B 5 / 18), comprising a lever and a fixed support which is made in a small arms, wherein the lever is connected to the fixed support, is made with the possibility of turning relative to the fixed support, and forms a kinematic pair with the fixed support, and is mounted at an angle to the axis of rotation of the lever relative to the fixed support.

[0010] This device has a number of significant disadvantages:

[0011] - The main disadvantage is that resulting from the impact of the index finger on the trigger blade, there is a torque of forces, the center of rotation of which is located in the grip, small arms, clamped in the palm of a human hand.

[0012] As a result, at the moment of firing, the weapon rotates in the palm of a human hand and leads to a shift in the aiming point and misses the target. - The presence of a rotatable sleeve on the trigger blade in any of the variants of the invention will result in reduced friction between the index finger and the trigger blade. Thus, the force applied to the trigger blade will freely change the angle of inclination with respect to the longitudinal axis of the weapon, which will lead to chaotic rotation of the firearm in the human hand, around the axis passing through the handle of the small arms clamped in the palm of the human hand, which in turn will lead to displacement of the aiming point and make a miss on the target. A device is also known:

[0013] "Trigger assembly" (patent US2020029222265A1 from 17.10.2020, cl. F41A 19 / 10), comprising a lever and a fixed support which is made in a small arms, wherein the lever is connected to the fixed support, is made with the possibility of turning relative to the fixed support, and forms a kinematic pair with the fixed support, and is mounted at an angle to the axis of rotation of the lever relative to the fixed support. This device has a number of significant disadvantages:

[0014] - is a very complex mechanical device in terms of design, which is also difficult to manufacture, assemble and operate, having large mass and overall dimensions.

[0015] - the trigger blade has two degrees of freedom, which will lead to arbitrary movement of the shooter's finger in two planes of trigger blade movement during firing, which will not allow to hold the weapon stably on the aiming line and, in turn, will lead to a miss on the target.

[0016] The device is closest to the claimed technical solution in terms of its technical essence and resulting technical result (for variants 1-3 of the invention):

[0017] "Laterally pivoting trigger lever" (patent EP3420294B1 from 25.11.2020, cl. F41A 19 / 10), which describes the various possible variants of the trigger blade.

[0018] Most closely related to variant 1 of the invention is a trigger blade for small arms, comprising a lever and a fixed support which is made in a small arms, wherein the lever is connected to the fixed support, is made with the possibility of turning relative to the fixed support, and forms a kinematic pair with the fixed support, and is mounted at an angle to the axis of rotation of the lever relative to the fixed support.

[0019] (see Fig. 2, of patent EP3420294B1).

[0020] Most closely related to variant 2 of the invention is a trigger blade for small arms, consisting of a slider, made with the possibility of rectilinear translational motion, relative to a fixed support, made in small arms, and forming a kinematic translational pair with the fixed support, whereby the trajectory of motion of the slider lies in the vertical plane, (see Fig. 1, of patent EP3420294B1). Most closely related to variant 3 of the invention is a trigger blade for small arms, consisting of a slider made with the possibility of making movement relative to a fixed support made in the small arms, and forming a kinematic pair with the fixed support, (see Fig. 1, of patent EP3420294B1).

[0021] The device described in patent EP3420294B1 has a few significant disadvantages: - The main disadvantage is that resulting from the impact of the index finger on the trigger blade, there is a torque of forces, the center of rotation of which is located in the handle, small arms, clamped in the palm of a human. As a result, at the moment of firing, the weapon rotates in the palm of the human's hand and causes the aiming point to shift and miss the target.

[0022] - One of the disadvantages of the present invention is that as a result of the rotation of the trigger blade relative to the longitudinal axis "A", an additional moment of forces relative to the handle of the small arms is generated, which leads to a displacement of the aiming point at the moment of firing in the horizontal plane, and consequently to a miss on the target.

[0023] - Also, rotation of the trigger blade relative to the longitudinal axis "A" causes unnatural movement of the shooter's finger, which causes discomfort and therefore will reduce the force of the finger on the trigger blade, and may even prevent the shooter from firing.

[0024] - Also, free rotation of the trigger blade around the longitudinal axis "A" in both directions relative to the plane "P" leads to uncertainty of the direction of rotation of the trigger blade around the longitudinal axis "A" at the initial moment of the shot, which, in turn, leads to an unnatural movement of the finger phalanges and makes it difficult or impossible to make a shot.

[0027] Ergonomic trigger blade for small arms (variant 2), consisting of a slider, made with the possibility of rectilinear translational motion, relative to a fixed support, made in small arms, and forming a kinematic translational pair with the fixed support, whereby the trajectory of motion of the slider lies in the vertical plane, wherein, according to the invention, the slider is made in such a way that the vertical plane in which the slider motion trajectory lies is located at an angle to the axis of the barrel of the small arms, the slider motion trajectory lying in the vertical plane is made at an angle to the horizontal plane or lies in the horizontal plane.

[0029] Advantageous Effects of Invention

[0030] The totality of features of the claimed technical solution (according to any of variants 1-3) allows to achieve a set of technical results:

[0031] - improve the accuracy of a small arms projectile hiting the target;

[0032] - eliminate the rotation of the weapon in the palm of the human's hand while firing, allowing for a safe and aimed shot;

[0033] - increase the controllability of small arms at the moment of firing, which will improve the accuracy of target shooting;

[0034] - maximizing the use of human finger movement energy due to the fact that the movement trajectory of trigger blade lever coincides or is close to the natural trajectory of motion of human finger flexion;

[0035] - possibility to realize any law of motion, interacting firing mechanism with trigger blade lever or to adapt it to already existing firing mechanisms of small arms.

[0067] Description of Embodiments

[0068] Used terms:

[0069] The term "trigger mechanism" or "firing mechanism" should be understood to mean the mechanism that activates the throwing function of small arms, such as firearms, pneumatic, mechanical and electric small arms. (https: / / en.wikipedia.org / wiki / Trigger_(firearms)).

[0070] The term "trigger" or "trigger blade" should be understood as a device in the form of a lever or slider that directly interacts with, and is part of, the human index finger and the trigger mechanism of a small arms, and serves to activate the trigger mechanism of the small arms. (https: / / en.wikipedia.org / wiki / Trigger_(firearms)).

[0071] The term "small arms" should be understood to mean a barrel weapon for firing bullets or other projectiles. Firearms, pneumatic, mechanical and electric small arms are distinguished depending on the source of energy for throwing the projectile. (https: / / en.wikipedia.org / wiki / Fire- armtTypes)

[0072] The term "lever" should be understood as follows: a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force. As such, the lever is a mechanical advantage device, trading off force against movement, (https: / / en.wik- ipedia.org / wiki / Lever).

[0073] The term "spike" should be understood as a protrusion formed on the end or side surface of a part and can fit into a correspondingly shaped and dimensioned slot or socket of another part. It is used for both permanent and periodical joints. It may be integral with the part or detachable. The term "slider" should be understood as a body representing a link of the mechanism, forming a kinematic, translational pair with a stationary link of the mechanism and making translational or curvilinear motion.

[0074] The term "vertical longitudinal plane" of a small arms should be understood as any plane passing through the small arms and parallel to or lying in the plane in which the axis of rotation of the barrel of the small arms is located and the ballistic trajectory of the projectile fired from the barrel of the small arms.

[0075] The term "human finger flexion plane" should be understood as the plane in which predominantly lies the movement trajectory of motion of the Distal phalanx of the human index finger, formed during the natural flexion of the human index finger, without pain and / or discomfort.

[0076] The term "axis of rotation of the lever" should be understood, geometrically it is a straight line around which all points of the lever make a circular rotation, and the plane in which lies the trajectory of at least one point of the lever is always perpendicular to the axis of rotation of the lever. The term "kinematic pair" should be understood as a connection between two kinematic links that ensures their relative motion. All kinematic pairs require constant contact between their elements, which is achieved either by means of certain forces or by giving the elements a certain geometric shape.

[0077] Embodiment of the invention (variant 1).

[0078] The trigger blade is an integral part of the firing mechanism of small arms. By means of a trigger blade, a human activates a small arm to fire a controlled, safe shot, wherein the trigger blade directly interacts with the human's index finger and the firing mechanism of the small arms and does not require additional parts or devices to transfer motion from the human's index finger to the firing mechanism of the small arms.

[0079] The firing mechanism of a small arms is not part of the invention and is shown by way of example to explain the invention. To explain the invention, a single-action firing mechanism is selected, which must be weighed before each shot is fired.

[0080] In the figure (Figs. 1, 3), there is shown, a firing mechanism comprising an ergonomic trigger blade 1. 1 for small arms, consisting of a lever 2 and fixed support 3, made in small arms, wherein the lever 2 is connected to the fixed support 3 and is made with the possibility of turning relative to the fixed support 3, kinematically connected with it, and mounted at an angle to the axis 4 of rotation of the lever 2 relative to the fixed support 3, wherein the lever 2 is mounted parallel or at an angle to the axis of the barrel of the small arms, and has a plane of rotation of the lever located at an angle to a vertical longitudinal plane. The sear 5 is mounted in the small arms with the possibility of turning relative to the fixed support 6 and interacts with the lever 2. The firing mechanism also has a striker-fired 7, which interacts with the sear 5. The sear 5 has a return spring 8 tightly pressing the sear 5 to the lever 2. Also, the striker-fired 7 has a firing spring 9.

[0081] When designing small arms, the anatomy of the human body is always taken into account to ensure a safe, controlled and aimed shot. By interaction, it is meant that the weapon is fixedly secured in at least one human hand, preventing the weapon from arbitrarily changing direction of aim, before firing and during firing. Also, to make a shot, a human must directly act on the firing mechanism of the small arms with at least one finger of one hand to make a safe, controlled, aimed shot. In this way, the at least one handle 10 of the firearm is always fixedly fixed in the palm of the at least one hand of the human. The human index finger consists (Fig.l) of three phalanges Distal, Middle, Proximal and is connected to Metacarpals which is part of the human palm and is stationary relative to the handle 10 (Fig.1,5, 6, 7) of the small arms, and all phalanges are jointed. In one particular variant embodiment, a small arms with a pistol grip 10 is selected (Figs. 1-6). In this variant, the plane of rotation of the lever 2 relative to the fixed support is perpendicular to the vertical longitudinal plane of the weapon. In this case, the plane of rotation of the lever 2 relative to the fixed support 3, is made in a plane or parallel to the plane of bending of the human finger.

[0082] But private variants of small arms other than the selected example are also possible, such as a rifle buttstock (Fig. 7), wherein the axis of the handle 10.1 is made at an acute angle «|3» (Fig. 7) to the axis of the barrel of the small arms. In such a variant embodiment, the human finger flexion plane may have an angle of inclination relative to the trunk axis. Also, the axis of rotation 4 of the lever 2, may coincide with the axis of rotation Middle phalanx of the index finger of a human (Figs. 8,10). In such a variant embodiment, the trajectory of the lever will be close to the trajectory of a human finger. Also, one of the variants provides for the removal of the axis of rotation 4 lever 2 beyond the pin that will increase the length of the lever and the moment of forces on the axis of rotation 4 lever 2 (Fig.9, 11). Also possible are private variants shown in (Fig. 12) axis of rotation 4 lever 2 is on the left of the barrel axis for left-handers, in (Fig. 13) axis of rotation 4 lever 2 is made to the right of the barrel axis for right-handers, in (Fig. 14) rotation axis 4 of lever 2 is at the center, universal trigger blade 1.1, in (Fig. 15) rotation axis 4 of lever 2 is on the right front, in (Fig. 16) rotation axis 4 of lever 2 is on the right with lever 2 at right angles to the barrel axis, and so on and so forth.

[0083] The lever 2 may have any geometric shape, cylindrical, rectangular, trapezoidal or the like. It may be curved or extended along the axis of rotation 4 (Figs. 1-4) and have, for example, a "C"-shape (Fig. 30,31) or (Fig. 1-4) or any other shape that satisfies the specifications of the selected design. The material of the lever 2 may be any material satisfying the technical parameters of the selected design, for example it may be made of metals or alloys thereof: steel, bronze, duralumin and / or polymeric materials and / or composite materials carbon, carbon fiber-reinforced plastic and etc. The lever 2 may also have a return spring (not shown in the drawing) allowing the lever 2 to return to its starting position before firing the shot. It can be a torsion spring associated with the axis of rotation 4 of the lever 2, compression or tension spring, coil spring, etc. or have no return spring of its own (Fig. 1) where the lever 2 returns to its starting position under the influence of the sear 5 and return spring 8. The lever 2 may also have an external stop (not shown in the drawing), made in small arms, limiting the turning angle of the lever 2.

[0084] Also, one particular variant embodiment provides that the lever 2 (Figs. 17-20) has a shaft 11 made coaxial with the axis of rotation 4 of the lever relative to the fixed support 3, with the possibility of turning relative to the fixed support 3, and kinematically connected to the fixed support 3, the lever 2 is made with the possibility of interacting with the firing mechanism of the weapon by means of the shaft 11. The at least one arm 2 (Figs. 8-11) has at least one spike 12 biased in the plane of rotation of the arm 2 relative to the axis of rotation 4 of the arm 2 relative to the fixed support 3.

[0085] The spike 12 may be made with the possibility of moving along the at least one arm 2 and the possibility of changing the length of an arm of the at least one arm 2. The spike 12 may have any geometric shape cylindrical, rectangular, may have a "C"-shape (Figs. 32-34) or any other shape allowing reliable interaction with a human finger. Also, the spike 12 may have an elongated shape (Fig. 16) to engage with two human fingers simultaneously. Also, the spike 12 may have a freely rotatable sleeve 13 (Fig. 27).

[0086] The material of the spike 12 may be any material satisfying the technical parameters of the selected design, for example it may be made of metal or metal alloys: steel, bronze, duralumin, etc. and / or polymeric materials and / or composite materials carbon, carbon fiber-reinforced plastic, etc.

[0087] In one particular variant, the at least one main arm 2 (Figs. 23-26) has at least one additional arm 2.1 made in series and kinematically connected to the main arm 2, wherein the additional arm 2.1 is made with the possibility of rotation relative to the main arm 2 in the plane of rotation of the main arm 2. Such a distinction, can help, to realize a safety device. The additional arm 2.1 may have any geometric shape. The material of the additional spike 2.1 may be any material satisfying the technical parameters of the selected design, for example, it may be made of metal or metal alloys: steel, bronze, duralumin, etc. and / or polymeric materials and / or composite materials carbon, carbon fiber-reinforced plastic, etc.

[0088] In one particular variant, the trigger blade 1.1 comprises at least one main lever 2 (Figs. 24-26) and at least one additional lever 2.2, made with the possibility of turning about the axis of rotation 4 of the main lever 2, and kinematically connected therewith, the main lever 2 and the additional lever 2.2 being spaced apart along the axis of rotation 4 of the lever 2 relative to the fixed support 3, the at least two levers being connected to each other by at least one spike 12.

[0089] The material of the additional arm 2.2 may be any material that satisfies the technical parameters of the selected design, for example it may be made of metal or metal alloys: steel, bronze, duralumin, etc. and / or polymeric materials and / or composite materials carbon, carbon fiber, etc.

[0090] Also, the above variants of trigger blade 1.1 may be combined with each other (Figs. 25,26) to achieve a more accurate match between the trajectory of the trigger blade 1.1, and the trajectory of the human finger. The interaction of lever 2 with the firing mechanism of small arms can be carried out directly by contact lever 2 and sear 5 and with the help of auxiliary kinematic pairs: cam mechanism (Figs.17- 20,21,24,24 ), gearing, screw pair, spatial cam mechanism, when the sear 5 makes simultaneous movement in the horizontal and vertical plane, in the form of hooks or stops, ratchet mechanism, eccentric, lever 2 and sear 5 can be a crank mechanism, etc..

[0091] In one particular variant, the plane of rotation of the lever 2 (Figs. 28-31) is made in a vertical plane, at an angle Q to the vertical longitudinal plane of the small arms.

[0092] In one particular variant, the lever 2 (Figs. 32-34) has at least one spike 12.1 made with the possibility of turning relative to the lever 2 in the vertical plane, and kinematically connected to the lever 2, for example hinged. By means of such a construction, the safety device is realized.

[0093] The material of the additional spike 12.1 may be any material satisfying the technical parameters of the selected design, for example it may be made of metal or metal alloys: steel, bronze, duralumin, etc. and / or polymeric materials and / or composite materials carbon, carbon fiber, etc.

[0094] In a possible particular case of the invention, the trigger blade 1.1 (Figs. 1-4) is made in the form of a lever 2 and a fixed support 3, wherein the plane of rotation of the lever 2 is made perpendicular to the vertical longitudinal plane of the small arms, and lies in the plane of bending of the finger of a human.

[0095] Before firing a small arms (Fig.1,3) index finger of a human touches the lever 2 Distal phalanx at the far point, relative to the fixed support 3, the handle 10 of the small arms is securely pressed against the palm of the human Metacarpals the rest of the fingers of the human hand. Lever 2 is in close contact with the sear 5 which is pressed against the lever 2 return spring 8, as well as the sear 5 is in engagement 19 (Fig. 1) with striker-fired 7, striker-fired 7 in turn pressed against the sear 5 firing spring 9, which is in a compressed state.

[0096] During the firing of a shot (Figs. 2,4), the Distal, Middle, and Proximal phalanges of the human index finger rotate relative to each other at radii Ri, R2, and R3, in a natural, naturally occurring manner relative to the human's stationary palm Metacarpals. Thus, the Distal phalanx moves along a curvilinear arc-shaped trajectory (Fig. 2). Under the influence of the human finger force, the lever 2 is rotated along the radius Ro relative to the fixed support 3 around the rotation axis 4. As a result, the sear 5 made in the form of a rocker slips on the surface of the lever 2, while rotating around the fixed support 6, and compresses the return spring s. As a result of the rotation of the sear 5, the sear 5 moves out of engagement with the striker-fired pin 7 and under the influence of the firing spring 9 performs progressive rectilinear movement along the barrel axis. As a result, the striker 7 strikes the cartridge primer (not shown in the drawing), resulting in a small arms shot. Thus the trajectory of motion of the lever 2 is closest in form and direction to the natural trajectory of motion of the Distal phalanx of the human finger, and the force arising on the lever 2, as a result of pressure of the human finger, is directed tangentially to the trajectory of motion of the lever 2 to the palm of the Metacarpals of the human, thus the direction of the force coincides with the direction of the forces formed by the other fingers of the hand and directed to press the handle 10 to the palm of the human. As a result, the fixation of the handle 10 in the human hand increases, while the direction of the barrel during firing does not change. That will eliminate the occurrence of torque of forces relative to the central axis of the handle 10 of the small arms, which in turn will increase the accuracy and safety of shooting from small arms.

[0097] Embodiment of the invention (variant 2).

[0098] Ergonomic trigger blade 1.2 (Figs. 35-38) for small arms, consisting of a slider 14, made with the possibility of rectilinear translational motion relative to a fixed support 15, made in the small arms, the trajectory of which lies in the vertical plane, in this case, the slider 14 is made so that the vertical plane in which lies the trajectory of the slider is located at an angle «p» to the axis of the barrel of the small arms.

[0099] Also, the motion path of the slider 14, may be made at any angle to or lying in a horizontal plane. The cross-sectional shape of the slider 14 may be any shape that satisfies the selected technical requirements, the cross-sectional shape of the slider 14 may be circular, rectangular, in the form of a parallelogram, I-beam, t-shaped, c-shaped and the like.

[0100] The slider 14 may be equipped with a return spring (not shown in the drawings) or may be returned to starting position by the sear 5 and return spring 8. The slider 14 may also have an external stop (not shown in the drawings), made in small arms, which limits the movement of the slider 14.

[0101] The material of the slider 14 may be any material satisfying the technical parameters of the selected design, for example it may be made of metal or metal alloys: steel, bronze, duralumin, etc. and / or polymeric materials and / or composite materials carbon, carbon fiber, etc.

[0102] In one particular variant embodiment of the invention, the trigger blade comprises at least one slider 14, wherein the at least one slider 14 has at least one spike 12.

[0103] The material of the spike 12 may be any material satisfying the technical parameters of the selected design, for example it may be made of metal or metal alloys: steel, bronze, duralumin, etc. and / or polymeric materials and / or composite materials carbon, carbon fiber-reinforced plastic, etc.

[0104] Further described is a possible particular case of an embodiment of the invention, trigger blade 1.2, in a variant wherein the trajectory of the rectilinear, translational movement of the slider 14 is made in a horizontal plane, and in a vertical plane made at an angle "p" to the axis of the barrel of the small arms.

[0105] Before firing the small arms (Figs. 35, 37), the index finger of the human touches the end of the slider 14. The handle 10 of the small arms is securely pressed against the palm of the human's hand by the remaining fingers of the human's hand. Slider 14 is in close contact with the slider 5, which is pressed against the slider 14 return spring 8, as well as the sear 5 is in engagement 20 (Fig. 35) with the striker 7, striker 7, in turn, pressed against the slider 5 firing spring 9, which is in a compressed state.

[0106] During the firing of a shot (Figs. 36, 38), the Distal, Middle, and Proximal phalanges of the human index finger rotate relative to each other at radii RI, R2, and R3, in a natural, naturally occurring manner relative to the human's stationary palm Metacarpals.

[0107] Thus, the Distal phalanx moves along a curvilinear arc-shaped trajectory. Under the influence of the force, the human finger, the slider 14 makes a rectilinear, translational movement relative to the stationary support 15.

[0108] As a result, the sear 5 made in the form of a rocker slips on the surface of the slider 14 rotating around the fixed support 6, while compressing the return spring 8. As a result of the rotation of the sear 5, the sear 5 moves out of engagement with the striker 7, and under the influence of the firing spring 9, makes progressive rectilinear movement along the barrel axis. As a result, the striker 7 strikes the cartridge primer (not shown in the drawing), resulting in the small arms being fired. Thus the trajectory of motion of the slider 14 is closest in direction to the natural trajectory of motion of the Distal phalanx of the human finger, and the force arising on the slider 14, resulting from the pressure of the human finger, is directed along the trajectory of motion of the slider 14 and directed to the palm of the Metacarpals human, with the direction of the force coinciding with the direction of the forces formed by the other fingers of the hand and directed to press the handle 10 to the palm of the human. As a result, the fixation of the handle 10 in the human hand increases, while the direction of the barrel during firing does not change. That will eliminate the occurrence of torque moment forces relative to the central axis of the handle 10 of small arms, which in turn will increase the accuracy and safety of shooting from small arms. Embodiment of the invention (variant 3).

[0109] Ergonomic trigger blade 1.3 (Figs. 39-42) for small arms, consisting of a slider , made with the possibility of movement relative to a fixed support 16, made in small arms, characterized in that the slider is made in the form of a ring or washer 17 or a segment of a ring 18 or a segment of a washer 17.1, with the trajectory of the slider is a segment of a circle located in a plane made at an angle relative to the vertical longitudinal plane.

[0110] The slider may be equipped with a return spring (not shown in the drawings) or returned to starting position by the sear 5 and return spring 8. The slider may also be equipped with an external stop (not shown in the drawings), made in small arms, which limits the movement of the slider. The material of the slider may be any material satisfying the technical parameters of the selected design, for example it may be made of metal or metal alloys: steel, bronze, duralumin, etc. and / or polymeric materials and / or composite materials carbon, carbon fiber, etc.

[0111] In one particular variant embodiment of the invention, the slider comprises at least one ring or washer 17 or ring segment 18 or washer segment 17.1, wherein the at least one ring or washer 17 or ring segment 18 or washer segment 17.1 has at least one spike 12.

[0112] Further described, a possible special case, the embodiment of the invention, in a variant in which the trigger blade 1.3 (Figs. 39-42) is made in the form of a slider consisting of a segment of the ring 18 and fixed support 16 made in the small arms, which together form a kinematic pair, wherein the trajectory of the slider 18 is a segment of a circle located in a horizontal plane perpendicular to the vertical longitudinal plane of the small arms.

[0113] Before firing the small arms (Figs. 39, 41), the index finger of the human touches the end of the slider 18. The handle 10 of the small arms is securely pressed against the palm of the human's hand by the remaining fingers of the human's hand. Slider 18 is in close contact with the slider 5, which is pressed against the slider 18 return spring 8, as well as the sear 5 is in engagement 21 (Fig. 39) with the boom 7, the boom 7, in turn, is pressed against the slider 5 firing spring 9, which is in a compressed state.

[0114] During the firing of a shot (Figs. 40, 42), the Distal, Middle, and Proximal phalanges of the human index finger rotate relative to each other at radii RI, R2, and R3, in a natural, naturally occurring manner relative to the fixed palm of the human Metacarpals.

[0115] Thus, the Distal phalanx moves along a curvilinear arc-shaped trajectory. Under the force of the human finger, the slider 18 moves along a curved arc-shaped path relative to the fixed support

[0116] 16. As a result, the sear 5, made in the form of a rocker, slips on the surface of the slider 18, while rotating around the fixed support 6, compresses the return spring 8. As a result of the rotation of the sear 5, the sear 5 leaves engagement with the striker 7, and, under the influence of the firing spring 9, makes progressive rectilinear movement along the barrel axis. As a result, the striker 7 strikes the cartridge primer (not shown in the drawing), causing the small arms to fire. Thus, the trajectory of motion of the slider 18 is closest in direction to the natural trajectory of motion of the Distal phalanx of the human finger, and the force arising at the end of the slider 18, resulting from the pressure of the human finger, is tangential to the trajectory of motion of the slider 18, and directed to the palm of the Metacarpals human, with the direction of the force coinciding with the direction of the forces formed by the other fingers of the hand and directed to press the handle 10 to the palm of the human. As a result, the secure fixation of the handle 10 in the human hand increases, and the direction of the barrel during firing does not change. Also, this invention will eliminate the occurrence of torque forces relative to the central axis of the handle 10 of the small arms, which in turn will increase the accuracy and safety of shooting from small arms.
