The invention relates to small arms, and is intended for all types of small arms that have triggers.

A device for compensation of errors when firing from small arms (trigger on RF patent No. 2113676)containing the tool placed between the hand and finger trigger, made in the form of predupredila with a warning ledge, established with the opportunity to interact with the finger arrow.

This device allows to improve the accuracy and marksmanship by controlling the shot of the moment of the descent of the hook on the sense output warning ledge by pressing your finger on the trigger.

The disadvantages of the known device, selected by the applicant as the closest analogue, should include limited opportunities for errors compensation when shooting, not to neutralize the negative impact of some components of complex finger movements arrow.

The technical result of the invention is to improve the accuracy of fire.

This technical result is achieved in that the device for compensation of errors when firing from small arms containing means, placed between the hand and finger trigger, according to the invention the said means is made is in the form of two platforms, the first of which is arranged to interact with the finger arrow, and the second with a trigger that has the ability to move one relative to another by contact surfaces with minimal friction force.

The device may be provided with a third platform located between the first and second platforms, and the platforms have the ability to move one relative to another by contact surfaces with minimal friction force and provided with means to return them to the original position, made in the form of an elastic yarns, fixed on the platforms.

In addition, the third platform is connected to the first and second platforms through the nodes of the connections made in the form of interacting projections and grooves response along the straight line on the contacting surfaces of adjacent platforms and ledges (grooves)located on the first platform, orthogonal projections (grooves), located on the third platform.

This set of essential features of the device to compensate for errors in the firing of small arms eliminates or at least significantly reduces the negative impact on the resulting shot some components of complex finger movements arrow in the process of pressing the trigger Crouch is to due to the motion of the platforms, perceiving ourselves the impetus of the movement of the finger arrow.

Described above essential features of the invention at the filing date is not known in the Russian Federation and abroad and meets the criteria of "novelty".

The invention can be implemented industrially using known techniques, technologies and materials and meets the requirements of the criterion "industrial applicability".

Device for compensation of errors when firing from small arms includes a tool placed between trigger 1 and finger 2 arrow, made in the form of United in block three platfo the m 3, 4 and 5 (see figure 2) or two platforms 3 and 4, when the trigger 1 performs the function of the platform 5 (see 11). Platform 3, which is intended to interact with the finger arrow made with the possibility of fixing on the finger 2 arrow using the fixation element 8 (for example, elastic thread), and the platform 5 is arranged to interact with the trigger 1 (see figure 2). Middle (intermediate) platform 4 is located between platforms 3 and 5, while the platforms have the ability to move one relative to another by contact surfaces with minimal friction force.

Platform 4 is connected to the platform 3 and 5 through the connection of nodes, elements are made in the form of interacting protrusions 6 and the return grooves 7 along a straight line on the contacting surfaces of adjacent platforms and ledges (grooves)located on the platform 3 (5), orthogonal projections (grooves)located on the platform 5 (3).

The platform can be equipped with means to return them to the original position, made in the form of fixed platforms elastic yarns (elastic) 9, round or rectangular cross-section, the desired elasticity sufficient to return the platform to its original position.

Figure 3, 4 and 5 show the design features of each platform in three dimensions. At present the certain drawings all platforms made rectangular, however, the shape of the platform can be any (circle, ellipse, triangle etc). Platforms can be interconnected, for example by the so-called "swallow's tail" (see, e.g., figure 3), which, of course, is not the only possible type of connection platforms. On Fig-10 presents other possible connections.

The platforms 3-5 elements and their compounds 6 and 7 may be flat and rectangular, but may be oval or curved for ease of placement, for example, on an oval (in cross section) of the surface of the trigger 1. On the lower projection figure 2 shows the "arcuate" platform 3-5 and nodes 6 and 7, providing a reliable contact platforms with the surface of the trigger 1 and finger-pointing arrow appears. The joints can be made as separate components, connected with the platform and in one piece with the respective platform.

Platform elements and their compounds can be rigid or flexible, that is, such that when the overlay platforms on the oval surface of the trigger is easily bent to fit the shape of this surface.

Items 6 and 7 compounds platforms can be performed not only at right angles, but at any other angle.

Platform 3-5 have the ability to move one relative to another to con acherousian surfaces with minimal friction force. This is achieved by performing platforms and knots of connections from a single material with a low coefficient of sliding friction, or a pair of materials with a minimum coefficient of friction, as well as implementation of the contacting surfaces with small roughness. You can also use lubricant, applied on the contact surface to reduce friction.

Device for compensation of errors during the shooting of firearms is as follows.

In General, movement of the finger arrow at the moment of pressing the trigger can be complex and includes at least two components. Figure 1 is a vector And indicates the direction of movement of the trigger. The main component of the movement of the finger coincides with the vector A, but a beginner arrow finger can move not only in direction but also in directions coinciding with the vectors or C. Simultaneously, the finger can be moved up or down relative to the trigger hook (figure 1 vectors of these movements not shown). As a result of some components of the complex movement of a finger that does not coincide with the vector A, is sergiana" shot.

The above described movement of the finger pressing the trigger can occur not only in novice shooters, but many professional who's shooters in extreme situations.

Itself the trigger with your finger arrow moves along the radius, the center of which coincides with the axis of mounting the trigger in the case of small arms. Such movement of the trigger a very negative effect on the result of the shot.

The work of the proposed device to neutralize the disturbing influences is carried out in two stages: preparation and proper compensation of errors in the implementation of the shot.

To verify the functionality of the device, made for example in the form of a block of three platforms, as shown in figure 2, we fix the block platforms 3-5 on the finger so that the platform 3 was located approximately on the middle phalanx of the finger. Finger of the other hand applied to the outer surface of the platform 5 and produced together with platform 5 arbitrary motion in the plane of the platform, for example, similar to the one shown in Fig.6 and 7. Pay attention to how to move and interact with one another platform 3-5 and what efforts they move. Efforts should be minimal. In the situation when all platforms are shifted one relative to the other, remove your finger from the platform 5, with means 9 return should return the platform to its original position. Original position provides maximum movement of the platform in any direction when firing.

Than the ranks verifies the operability of the device variants, shown at 11 and 12.

After testing the device, the shooter establishes a finger fixed on the device to trigger 1, providing a reliable contact of the outer surface of the platform 5 with the surface of the trigger (this is necessary to ensure that the platform was in the original position), and makes a shot. Suppose that this particular arrow barrel during firing is rejected, for example, to the right and down, which also contributes to moving the trigger on "radius". The main component of the complex movements of the finger during the pressing on the trigger 1 is directed along the axis of the barrel. Affecting the shot component of the complex movements of the finger during the pressing on the trigger, deflecting the barrel down (let's call it "Y-component"), will be neutralized by the moving platform 3 with finger arrow oriented along the vertical connection of platforms 3 and 4, formed by the elements 6 and 7, and rejects the barrel down. Since moving platform 3 relative to the platform 4 by the contact surfaces is carried out with minimum force of sliding friction, momentum transfer movement of the trigger from the unwanted component of the complex movements of the finger arrow will not happen. Negatively impact the plans for the shot component of the complex movements of the finger during the pressing on the trigger, deflecting the barrel to the right (let's call it "X-component"), will be neutralized by moving your finger arrow together with the platforms 3 and 4 to the right along the horizontally oriented connection platforms 5 and 4 and will not reject the barrel to the right. Since moving platforms 3 and 4 relative to the platform 5 is also carried out with minimum force of sliding friction, momentum transfer movement of the trigger from the unwanted component of the complex movements of the finger arrow and in this case will not occur.

Thus, as a result of moving platforms, perceiving impulse "wrong" finger arrow, the disturbance X - and Y-components of the motion is neutralized.

Similarly is the compensation of the errors of the shot when using the device (see 11) with two platforms (the third platform 5 is combined with a trigger 1, in which the element is made of the connection protrusion 6), as well as devices with three platforms without joints between them (see Fig). All possible variants of the device error shot neutralised by the movement of the platforms, on perceiving himself to the impulse of movement of the finger arrow.
