Description

1. The technical field

The system for preventing the destruction of shells during their power supply to the charging chamber of the marker (hereinafter also: SPRS, system) is used in markers (simulators of small arms) used in the paintball game. It is designed to prevent the occurrence of mechanical loads on the body of this projectile during the power supply of the projectile to the charging chamber, which can lead to its destruction. The application of the system provides a significant reduction in delays during shooting, thereby improving the quality of games or training.

This system can also be implemented in other types of pneumatic weapons or mechanisms.

2. The level of technology

Currently, the paintball game uses mainly balloons as a projectile and, more recently, bullets are increasingly gaining popularity, structurally executed on the basis of the "shuttle" ("First strike", "One to one") principle. The second, due to aerodynamic stabilization in flight, gives a slight increase in the aiming range and provides a significant increase in firing accuracy.

Both types of shells consist of a thin, easily destructible shell and a filler - liquid paint or powder. The strength of the shell is designed in such a way as to withstand the pressure of the gas and other forces acting on it during movement along the bore and to collapse at the moment of impact on the obstacle with the maximum probability.

This property of the shell shell makes high demands on the operation of the marker mechanism in the process of supplying this projectile to the sending line and directly in the process of sending it to the barrel. Any significant mechanical effect of the marker elements on the fragile shell of the projectile can cause its destruction, which leads to a long, difficult to fix delay in shooting.

Since the presented system is intended for use in markers with power feed, the factors that can lead to the destruction of the projectile will be considered on the example of magazine feed widely used in simulation markers. In such stores, the movement of shells into the charging chamber of the marker is carried out under the action of the spring from the bottom up (lower feed).

The first factor is directly related to the quality of the shells used, and primarily the balls.

When applying (Fig. 1) to the charging chamber of marker 1 (shutter 2 cocked), the next ball 3 passes a distance S, at least equal to its diameter, with acceleration determined by the force of action of the power drive (in this case, the store spring) and the mass simultaneously given by this drive balls. The kinetic energy when the ball 3 hits the wall of the charging chamber is comparable to the kinetic energy that occurs when the ball falls from a height of 1 m. This energy is sufficient to cause the shell of the ball 3 to split if it hits the hard surface in case of defective zones or poor-quality weld joint connecting its hemispheres.

The second factor is associated with the position of the projectile on the line sending to the barrel.

When using balls (Fig. 2). The diameter of the charging chamber (channel in the housing of the marker 1, in which the shutter 2 moves) is 0.5-1 mm larger than the diameter of the ball 3 to ensure the free movement of the latter into the barrel channel. The dispersion of the calibres of the produced balls, their ellipsoidity, elastic deformation of the shells of the balls at the point of contact leads to the fact that the subsequent (lower) ball 4 can enter the charging chamber, the diameter of the inner channel of which corresponds (taking into account the established clearance) to the diameter of the shutter body 2, by 2-2.5 mm. With the beginning of the shot cycle, the shutter 2 faces the ball 4 with the face of the mirror, sinking it into the store, as a rule, without consequences. However, there is some likelihood, directly related to the quality of the balls used, of the destruction by the face of the shutter mirror 2 of the shell of the ball 4.

When using bullets, "shuttlecocks. Unlike a ball, such a projectile should be fed exclusively by the head in the direction of the bore. Structurally (Fig. 3) such" shuttlecocks "are made as follows: the head part in the form of a hemisphere with a charge of paint placed in it and the tail part in the form of a skirt with small stabilizers around the perimeter.The length of the bullet is almost equal to its diameter.With this design, its center of gravity is significantly shifted forward, which leads to a tipping moment. the next “shuttlecock” supports it, preventing it from tipping over. During the shot (Fig. 4), the edge of the mirror of the forward-moving shutter 2 can pick up the supporting “shuttle” 4 for the sharp edge of the skirt, which, even with little effort, along with the rounded shape of the head the projectile leads to its rotation, feeding in this position and the destruction of the bolt 2 in the next shot cycle.

The most significant third factor that can cause destruction of the projectile is the lack of synchronization of the operation of the system for feeding it to the sending line into the barrel with the movement of the shutter. The absence of this synchronization can lead to a situation (Fig. 5), when the forward-moving shutter 2 sticks into the undershot shell 3 and destroys it.

Reducing the impact of these factors can dramatically reduce the number of delays during shooting and thereby improve the quality of games (training).

Special design solutions to reduce the impact of the first negative factor are not known. The limitation of its influence is to reduce the feed rate of the shells, for example, by installing a weaker magazine spring. This, in turn, reduces the reliability of the feed and leads to an increase in delays caused by the lack of synchronization of the shot cycle (the influence of the third factor).

Insignificant attention is paid to the impact of the second negative factor associated with the position of the projectile on the delivery line in existing modern paintball markers. One known solution to the problem (Fig. 6) is to perform a longitudinal cut on the body portion of the shutter 2 facing the feed window, eliminating the impact of its mirror face on the next projectile 4. This design has a serious drawback (Fig. 7) - the shutter 2 does not completely lock the barrel channel and, in the course of the shot, a significant part of the gases breaks out of the barrel channel through the formed window into the housing of the marker 1. This loss requires, to ensure a given initial velocity of the projectile, increased gas flow.

In modern markers, the problem of the third factor is solved in two ways.

In markers the so-called Ηi-end class, whose work is controlled by programmable electronics, the synchronization problem is solved by introducing, for example, optical sensors, which, in the absence of a ball on the sending line, do not give an enable signal to release the shutter.

In simpler, but at the same time more common mechanical markers, this problem is solved differently by introducing a mechanical lock into the marker design, which prevents the bolt from moving if the projectile fails to send to the sending line.

Currently known is a commercially available system of the company RAP - RAP4 Lok-Bolt Anti Chop System (patent US 20120325192 A1) for markers of this company with store (lower) feed (Fig. 8). It is a blocker, the main body of which is made of metal (steel) in the form of a one-arm lever 5, mounted along the line of the barrel channel in the marker body 1 directly above the shop window on axis 6 with the possibility of rotation relative to it. Under the action of the spring 7, the lever 5 is lowered down into the space of the charging chamber, while its end is located opposite the cocked shutter mirror 2. In the absence (Fig. 9) of the projectile 3 on the sending line, the shutter 2 comes off from the sear when the trigger is pressed and stops at the end of the lever 5. To continue firing, it is necessary to cock the bolt 2 and eliminate the cause of the absence of projectile 3. With (Fig. 10) a normally supplied projectile 3 (standing on the sending line), lever 5, when it is rotated around axis 6, rises, leaving wide However, it doesn’t interfere (Fig. 11) with the shutter 2 moving forward. The fixation (Fig. 10) of the projectile 3 supplied (according to the patent) is ensured by an elastic retainer 8 mounted on the lower edge of the lever 5. Thanks to its curved shoulder, it holds the projectile 3 fed to the sending line from inertial movement in the direction of the barrel channel during various manipulations of the player with the marker because the weight of the projectile 3 is significantly less than the elastic force arising from the extension of the shoulder of the latch 8. When (Fig. 11) the shutter 2 moves forward (with the start of the shot cycle) under its influence, the projectile 3, acting on the shoulder of the latch 8, unbends it (pressure force of the shutter 2 on projectile 3 significantly exceeds the elastic force arising in this shoulder during elastic deformation) and passes into the barrel. With the shutter 2 retracting to the cocked position, the shoulder of the retainer 8, freed from its influence, returns to its original position under the influence of the elastic force, which prevents the new projectile being delivered from moving in the direction of the barrel bore.

The RAP4 Lok-Bolt Anti Chop System considered is a prototype of the claimed invention.

This system is characterized by relative simplicity and reliability in operation, however, it has the following disadvantages.

1. Does not exclude the effects of the first and second negative factors.

2. When the lock is triggered, the main body of the blocker experiences an impact load from the side of the accelerating shutter, which, to ensure the required resource, places high demands on the structural strength of the assembly and the material of the shutter itself.

3. The system consisting of small elements (projectile retainer, lever, spring, axis, etc.) is difficult to maintain in the field - there is a great risk of losing any part. The process of sorting and cleaning takes a relatively long time.

3. Disclosure of invention

The system for preventing the destruction of shells during their power supply to the charging chamber of the marker must meet the following requirements.

1. Reliably stop the moving shutter in the absence of a projectile in the charging chamber on the sending line at any position of the marker, including in difficult conditions, for example, when contaminated.

2. Position in the charging chamber of the marker on the sending line any of the existing types of missile projectiles used in paintball, excluding partial entry into the charging chamber of the projectile subsequent to the one sent to the sending line.

When using bullets, "shuttlecocks" - to prevent the bolt from catching and turning, the position of the next projectile, with the start of the shutter movement, should be such as to exclude contact of the latter with the edge of its skirt.

3. Reduce the shock load on the shell of the projectile when it is fed into the charging chamber.

4. Possess sufficient resource and wear resistance.

5. To be as simple as possible constructively.

6. To be easy to maintain, incl. and in the field.

The elimination of the disadvantages inherent in the prototype, the full implementation of the above requirements was laid down in this invention.

The principle of operation of the SPRS is similar to the principle of operation of the prototype - the locking lever rotating on the axis stops the shutter in the absence of a projectile sent to the sending line or passes the shutter if it is present.

The essence of the invention lies in the fact that all elements of the system except the axis are combined into a single part made of elastic material - a blocker mounted on the axis of rotation, the configuration of which is a combination of the main body and several protruding elements of a given shape. These main body and elements, in the course of work, when interacting with the projectile supplied, the marker body, the shutter form elastic levers and, being their shoulders, due to the elastic force arising from their elastic deformation, provided by the physicomechanical properties of the material from which a lock is made, they perform not only all the functions of the prototype elements included in the lock system: the main body of the lock - to lock and unlock the movement of the shutter, the springy shoulder - hold the lock in position “blocking” in the absence of projectile supply, the projectile retainer - to keep the projectile fed into the charging chamber from inertial movement in the direction of the barrel channel, but also allow the blocker to perform functions to prevent the effects of the remaining negative factors mentioned above.

So, the predetermined positioning of the projectile on the sending line to the barrel channel is achieved by placing the projectile in a position opposite the entrance to the barrel channel with some offset towards the feed window. In this position, the subsequent projectile does not enter the space of the charging chamber, i.e. does not cross the shutter channel. The positioning of the projectile being sent — the “shuttlecock” bullet — is additionally performed at a slight angle to the longitudinal axis of the barrel channel, providing a distant position for its rear part. In this case, the next projectile abutting against it will be located at the same angle. A moving bolt, sending a shuttlecock into the barrel and passing the face of the next projectile's skirt with the edge of the mirror, does not touch it and begins to contact the side surface of the bullet much closer to its center of gravity, virtually eliminating the possibility of rotation.

This positioning of the projectile is ensured by the constructive ability of the blocker to occupy, unlike the prototype, not two positions - "lock" and "unlocked", but three - with the separation of the unlocked state into two positions: "fixation of the projectile" and "extreme". In the process of supplying a projectile at a given point of rotation of the blocker, an element is formed that forms an additional lever, the elastic deformation of the shoulder of which causes a stepwise increase in the total elastic force that counteracts the power drive. So, at the first stage of rotation - from the "lock" position to the "fixation of the projectile" position, the feed lever formed by the main body of the blocker (the supplied projectile acts on it) and a spring-loaded shoulder work. The elastic force arising during the elastic deformation of a given shoulder is aimed at returning the blocker to its original position and its moment is much less than the torque of the force acting on the supplied projectiles of the power drive, therefore it does not interfere with the feed.

With the arrival of the blocker in the "fixation of the projectile" position, abutting against the marker body, an additional element is connected - the projectile fixation arm. Along with the existing feed lever, the main body and this shoulder form a new lever - the locking lever. With further rotation of the blocker, the resulting elastic deformation of the fixing shoulder sets the elastic force, the moment of which, together with the moment of the elastic force arising from further elastic deformation of the spring shoulder, exceeds the torque of the force acting on the projectile of the power drive and prevents further rotation of the blocker. Thus, a predetermined fixed position of the projectile on the sending line is achieved.

This solution also reduces the impact load on the shell of the projectile when it is fed into the charging chamber due to the shock-absorbing action of the projectile fixation lever by short-term bending of the projectile energy absorbing kinetic energy. Thus, the effect of the first (see above) negative factor is reduced.

The "fixation of the projectile" position corresponds to the unlocking position and does not prevent the bolt from moving forward with the start of the shot cycle. At the same time, since in this position the blocker enters somewhat into the channel of movement of the shutter, the latter, with the start of movement, acts on it. The shape of the lock sets the component of the pressure force of the shutter on the lock in the direction of rotation of the latter to the "extreme" position. Since the moment of force of this component significantly exceeds the counteracting total moment of elastic forces arising from the elastic deformation of the locking shoulder and springy shoulder, the lock under its action rotates or bends, occupying the above position, and does not impede the forward movement of the shutter.

In the "locked" position, the lock is located with the front face opposite the shutter mirror. In this position, with the start of movement, the shutter abuts against this face of the blocker. The shape of the blocker, the position of its axis, the interaction with the marker body determine the direction of the components of the gate pressure force on it. The elastic forces arising as a result of slight elastic deformation of the body of the blocker compensate for the action of these components without changing the position of the blocker, thereby allowing it to prevent further movement of the shutter. Such depreciation allows you to smoothly absorb the kinetic energy of a moving shutter, eliminating the shock load on the elements of the system.

For the convenience of handling the lock, an additional blocking element may be a trip arm, which forms a two-arm lever with the main body. This shoulder does not work in the process of passing the feed and firing cycles, but due to the fact that it goes beyond the marker body, it allows you to push the lock to the unlocked position by pressing it. This feature allows you to disable the lock to check the performance of the marker, for example, by conducting a blank firing. In the particular case of execution, the shoulder of the shutdown can be performed by the shoulder of the fixation of the projectile, provided that it is executed with the exit beyond the marker body.

The elastic properties of the material of the blocker allow you to set it on the axis in tension, thereby fixing their connection. This prevents the axis from falling out, eliminating the need for additional technical solutions to fix it. This design is extremely simple both in manufacturing and in maintenance.

The material for the manufacture of the blocker can be, for example, polyurethane having high physicomechanical properties: elasticity, low abrasion, high strength, high tear and multiple deformation resistance, increased hardness, low thermal conductivity, preservation of elasticity at low temperatures and operating temperature range from - 50 ° C to 110 ° C, ozone resistance, water resistance, resistance to microorganisms and mold and chemical inertness.

5. The implementation of the invention

The device of the warning system for the destruction of shells in the process of their power supply to the charging chamber of the marker.

The system lock is a monolithic part made of an elastic material. It can have a rather diverse arrangement of the elements included in it, their shapes and sizes, while the algorithm for their operation will be identical. The most optimal, from the point of view of production and operation, the manufacturing option of the lock in the form of parts with a thickness of 6-8 mm with the placement of all the protruding elements in one plane (Fig. 12).

The lock is installed (Fig. 13) in the longitudinal slit-like cut-out of the marker body 1, facing the charging chamber opposite the feed window, or in a removable block rigidly mounted in the marker body 1. It is fixed on axis 6, allowing it to rotate in a plane longitudinal to the axis of the bore.

The blocker includes the following elements: the main body, the springy shoulder, the shoulder of the fixation of the projectile, the latch, the shoulder off.

The main body 5 is actually a locking lever and is the most massive part of the lock. The rotation of the lever relative to the axis 6 at predetermined angles is limited by the walls of the housing 1 of the marker or other elements rigidly connected to this housing.

The end part of the main body 5, facing the projectile 3, has a facet beveled towards the side of the shutter mirror 2.

Spring shoulder 7 acts as a spring of the lock. The optimal location is radially relative to the axis of rotation 6 of the blocker, interacting with the housing 1 of the marker or other element rigidly connected to the housing.

Shutdown arm 9 - an additional element that is not involved in the system during the shot. Designed to disable the lock manually by clicking on it.

The shoulder of fixation of the projectile 10 is either a separately made element, or (Fig. 14) is defined by the interaction of the main body of the blocker 5 with the marker body 1 or (Fig. 15) with the element rigidly installed in the body 1. This (Fig. 16) arm 10, being a separately executed element, can additionally fulfill the function of a disconnection arm, provided that it is executed with the marker outside the housing 1.

The latch 8 (Fig. 13) is made in the form of a shoulder on the lower edge of the main body of the blocker 5. Designed to limit the possibility of movement of the projectile 3 into the bore until the start of the shot cycle. The shape of the latch 8 provides a predetermined positioning of the projectile 3 in the charging chamber on the sending line.

Alternatively, it can be performed separately installed in the housing 1 part, which leads to the complexity of the system and will not be considered further.

The axis of rotation 6 passes through a hole made in the main body of the blocker 5. The diameter of the hole is slightly smaller than the diameter of the axis 6, which ensures its tight fit to prevent interference. In this case, the axis 6 rotates freely in the landing holes of the housing 1 of the marker.

Work SPRS.

The blocker installed (Fig. 13) on the axis 6 in the notch of the marker housing 1 rests with the spring shoulder 7 against the wall of the housing 1 and, due to its elastic force, is held in the “locked” position, positioned by the end face of the main body 5 opposite the shutter mirror 2. The trip arm 9, protruding from the housing 1 to the outside, allows you to visually control the position of the blocker (the presence of a projectile on the sending line) and makes it possible to manually disable the lock.

The operation of the system in the absence of a projectile on the line sending to the bore or undersupply.

When you press the trigger (Fig. 17), the shutter 2 comes off the sear and, moving forward, rests against the end face of the main body 5, which is a locking lever. The pressure force of the shutter 2 acting on the lever has two main components. The first, largest, is directed to axis 6 and is compensated by the elastic force that counteracts it when the main body is compressed. The second is to rotate inward the charging chamber relative to this axis. Since the rotation of the lock in this direction is limited by the housing 1 of the marker, the action of this component of the pressure force of the shutter 2 is aimed at bending the main body of the lock 5, which has the greatest stiffness in this direction. The elastic force arising during its slight elastic deformation compensates for the action of this component of the pressure force of the shutter 2 and stops the latter, preventing it from moving forward. Such a damping stop of the shutter 2 practically eliminates the shock load on both the axis 6 and the mirror of the shutter 2.

Work when feeding a projectile.

The projectile 3 delivered (Fig. 18) from the magazine is stabilized relative to the lock, abutting the front hemisphere against the contour of the retainer 8 repeating its contour. Then, acting on the elastic two-arm feed lever formed from the main body 5 and the spring arm 7, it rotates (since the torque of the force of action of the power drive significantly exceeds the opposing moment of the force of elasticity of the deformable springy shoulder 7) it is in the position "fixation of the projectile". In this position (Fig. 19), the blocker abuts against the marker body 1 or an element rigidly connected to it, forming a projectile locking lever with the following possible options.

1. The element (Fig. 19), (Fig. 20), which is the shoulder of the fixation of the projectile 10. In this case, an elastic two-shoulder fixing lever is formed from this shoulder and the main body of the blocker 5 with the axis of rotation relative to the axis 6 of the mounting of the blocker.

2. (Fig. 21) with the main body 5 in a protrusion on the marker body 1 or an element rigidly mounted on the body 1. In this case, the shoulder of fixation of the projectile is set relative to the point of this contact, forming a lever of fixation. Further, in view of the identity of the work, only the option with a protrusion on the marker body 1 will be considered.

Further (Fig. 19, Fig. 20, Fig. 21) the lifting of the blocker is impossible, because the total moment of elastic forces of the springy shoulder 7 and the fixing shoulder 10 significantly exceeds the torque of the force of the power drive.

When the rotation of the bollard is stopped in the "projectile fixation" position, the kinetic energy of the projectile (s) supplied by the magazine spring is absorbed by the short-term shock-absorbing flexible deformation of the fixation arm 10, which acts as a damper.

The lock is in the "fixation of the projectile" position - partly leaving the beveled face of the main body 5 opposite the shutter mirror 2. Its lower face ensures the position of the projectile 3 fed to the sending line with some offset towards the feed window, which prevents the subsequent projectile 4 from leaving the line the movement of the lower point of the shutter mirror 2, and the “shuttlecock” 3 bullet (Fig. 22) also with the lower edge of its skirt lowered.

With the beginning (Fig. 23, Fig. 24, Fig. 25) of the shutter 2 moving forward, the edge of its mirror, running onto the beveled face of the end face of the main body 5 of the blocker, tends to turn it up. The component of the pressure force of the shutter 2, aimed at the rotation of the blocker, creates a moment of force significantly exceeding the total moment of elastic forces arising from the deformation of its shoulders - spring 7 and fixation 10, and makes them bend. The lock leaves the space of the charging chamber, releasing the shutter 2 turn.

The shutter 2, starting to push the feed projectile 3 in the direction of the bore, passes over the feed window without catching another shell 4 - a ball or shuttlecock (Fig. 26) with the edge of the mirror.

Sent (Fig. 23, Fig. 24, Fig. 25) by the shutter 2, the projectile 3 unbends the lock 8 and passes into the bore.

With the return, after firing, the shutter 2 to the rear position, the blocker freed from its action under the action of the expanding shoulder of fixation 10 and the spring shoulder 7 falls down, occupying the initial position of "lock". The projectile retainer 8 also returns to its original shape. The cycle is over.

The system according to claim 7, characterized in that in the particular case of the execution, the blocker contacts the body of the marker or the element rigidly fixed to it directly by the main body, defining the fixation arm relative to the point of this contact and thus forms a flexible fixation lever. 10. The system according to p. 4, characterized in that in the particular case of execution, the side of the blocker facing the projectile has a bevel towards the side of the shutter mirror, made with the possibility, in the position of the blocker "fixing the shell", under the influence of the face of the mirror moving forward the shutter to set the component of the shutter pressure force, the vector of which is directed to the side of rotation of the blocker to the “extreme” position and the moment of force of which significantly exceeds the total moment of elastic forces arising from this rotation during elastic deformation ruzhinyaschego shoulder and shoulder fixed shell. 11. The system according to p. 1, characterized in that in the particular case of execution, the hole in the blocker, intended for its installation on the axis, is made with a diameter slightly smaller than the diameter of the axis with the possibility of stretching to cover its tightness, thereby rigidly fixing the connection. 12. The system according to p. 1, characterized in that in the particular case of execution the configuration of the blocker has an element - a trip arm, made with a partial exit from the marker body with the possibility of pressing the protruding part by hand with a force whose moment exceeds the moment of elastic force, arising during elastic deformation of the springy shoulder, turn the lock from the "lock" position to the "fixation of the projectile" position. 13. The system according to p. 8, characterized in that in the particular case of execution, the fixing shoulder is made with a partial exit from the marker body with the possibility of pressing the protruding part with a hand with a force whose moment exceeds the moment of elasticity arising from the elastic deformation of the springy shoulder , turn the lock from the “lock” position to the “lock projectile” position.
