Description

The utility model relates to the designs of markers for the game "paintball", namely to systems for preventing the destruction of shells in the process of their power supply to the charging chamber of the marker. The system is a blocker installed on the axis in the body of the marker. The bollard is a single piece and can be made of metal (or other material) that has low weight and sufficient strength, and is not subject to corrosion in a humid environment. Protruding elements are made on its body, which, interacting with the marker body, the shutter, the projectile supplied, provide a solution to the problems of positioning this projectile in the charging chamber on the line of delivery to the barrel bore and stopping the shutter in case of violation of its supply. In addition, the second function of the device is to prevent a projectile already placed in the marker chamber from falling out when a magazine or similar device that feeds projectiles into the marker is disconnected.

1. Technical field

The blocking device of the marker shutter in case of violation of the power supply of the projectile into the charging chamber, while simultaneously preventing the projectile from falling out of the chamber (hereinafter also: UBZM, device) is used in markers (simulators of small arms) used in the game "paintball". It is designed to prevent the occurrence of mechanical loads on the body of this projectile during the process of force feeding the projectile into the charging chamber of the marker, which can lead to its destruction. The use of the system provides a significant reduction in delays when firing, thereby improving the quality of games or training.

This device can also be implemented in other types of pneumatic weapons or mechanisms, and under certain conditions in firearms.

2. State of the art

Currently, in the game of paintball as a projectile, mainly balls and bullets with plumage ("First strike"), structurally made according to the "flounce" principle, are used as a projectile.

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

This property of the shell of the projectile places high demands on the operation of the marker mechanism and, in particular, on the synchronization of the system for feeding balls into the charging chamber. Charging chamber - the space between the front end of the cocked bolt and the breech breech, in which the projectile fed to the line of reloading into the barrel bore is located. In the absence of this synchronization, a situation is very likely when the moving bolt hits a projectile that has not been fed into the charging chamber and destroys it, causing a delay in firing, the elimination of which requires considerable time.

In markers, the so-called. Hi-end class, the operation of which is controlled by programmable electronics, the synchronization problem is solved by introducing, as a rule, optical sensors, which, in the absence of a ball in the charging chamber, do not give an enabling signal to release the shutter.

In simpler, but at the same time, more common mechanical markers, this problem is practically not solved. The whole calculation is based on reducing the probability of a ball splitting by introducing such measures as limiting the rate of fire, having only semi-automatic firing mode and using power-driven feed systems that forcibly increase the speed of the balls.

Recently, paintball markers are increasingly used as a simulator of small arms, not only for military-style games, but also for training fire fighting at short distances by law enforcement officers. For these purposes, mechanical markers are used as the most reliable and easy to use. There are models, in terms of dimensions, design, to the maximum extent corresponding to military weapons. They use feed systems that mimic real magazines in terms of size and handling. In such stores, the supply of balls is carried out under the action of a spring from the bottom up (bottom feed). Power delivery reduces the likelihood of a ball split, but does not eliminate it, and the occurrence of delays reduces the quality of training.

The lack of synchronization of cycles in a mechanical marker can be compensated by introducing a simple and reliable mechanical blocking device into the design, which excludes the possibility of splitting a fragile projectile by a forward-moving bolt if the latter is not fully fed into the charging chamber and does not allow a blank shot to be fired. This solution allows you to drastically reduce the number of delays when firing, which contributes to maximum imitation when using the marker as a simulator for individual small arms.

At the moment, a device for mechanical firing blocking by RAP4 is known - Lok-Bolt Anti Chop System (patent US 20120325192 A1). Produced as an upgrade to the markers of this company with magazine (bottom) feed (Fig. 1). It is a lever 1 located along the line of the bore in the housing 2 directly above the magazine window, rotating on axis 3 perpendicular to the axis of the bore and perpendicular to the line of motion of the balls being fed 4. Under the action of the spring 5, the lever is lowered down, while its end is located opposite the front cut cocked bolt 6. In the absence of ball 4 in the charging chamber or its undersupply (Fig. 2), when the trigger is pressed, the bolt 6 comes off the sear and stops, resting against the end of the lever 1. To continue shooting, it is necessary to cock the bolt 6 and eliminate the cause of the absence of the ball 4. When the ball 4 is normally fed (it stands on the delivery line) (Fig. 3), the lever 1 rises under its influence, compressing its spring 5, and does not interfere with the movement of the shutter 6 forward (Fig. 4). The considered system RAP4 Lok-Bolt Anti Chop System serves as a prototype of the claimed utility model. This UBZM is simple and reliable in operation, but it has the following disadvantages.

When the lock is activated, the main body of the lock experiences a shock load from the side of the accelerating shutter, which, in order to provide the required resource, imposes increased requirements on the structural strength of the assembly and the material of the shutter itself.

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

It is possible that a player decides to change an empty magazine to a loaded magazine, forgetting to pre-cock the bolt, for example, contamination that prevents the lever from fully lowering, or wear of its end part, etc. contributes to the fact that this lever, resting against the front section of the shutter, is on the verge of failure, then, at the moment of connecting the full magazine, under the influence of the impact force of the supplied ball, it turns to release the shutter. There is an accidental firing. This situation is very dangerous if it happens outside the playing field.

Fourthly, when the lock is activated, the lever axis is subjected to a direct shock load, which increases the requirements for the strength characteristics of the system elements.

3. Disclosure of utility model

The device for preventing the destruction of projectiles in the process of their power supply to the marker's charging chamber must meet the following requirements.

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

2. Eliminate the interaction of the blocker lever with the front cut of the shutter, leading to its wear and tear, by transferring shock loads to the outer body of the shutter frame.

3. Hold and position the projectile already in the marker's charging chamber on the firing line, if there is no support pressure from the magazine spring.

4. Reduce the impact load on the projectile body when it is fed into the charging chamber.

5. Have sufficient resource and wear resistance.

6. Be structurally simple as possible.

7. Be easy to maintain, incl. and in the field.

The technical problem that the device is aimed at is the elimination of the disadvantages inherent in the prototype, while maintaining the simplicity of the design, as well as the introduction of an additional function that increases performance, was incorporated in this utility model.

The technical result consists in eliminating the impact load on the projectile body during feeding into the charging chamber and keeping the projectile from falling out, in improving the operational characteristics of the marker, in increasing the reliability of its operation, in simplifying the operation of the marker.

The technical result is achieved by the fact that the lever of this lock, located opposite the projectile filed on the delivery line and having the ability to rotate about its axis, rigidly fixed in the marker body, unlike the prototype, is placed not along the longitudinal axis of the bore, but across it - along the line ball supply. This position allows the lever to interact with the projectile already in the initial phase of the projectile's movement from the feed magazine, thereby being able to block the shutter almost throughout the projectile's path to the charging chamber. The location of the lever along the line of motion of the projectiles being fed, in combination with its shape, ensures the stabilization of the supplied projectile when moving to the firing line and securely fixes it in the charging chamber, preventing the projectile from falling back into the opening of the charging chamber, in the case when the magazine is unfastened. In addition, unlike the prototype, the transfer of shock loads, when the lock is triggered, from the front cut of the bolt to the outer body of the bolt carrier, as well as from the lever axis to the marker body, increases the reliability of the system.

5. Implementation of the utility model

Marker shutter locking device (Fig. 5).

The lever 1 is the main blocking element, which is an L-shaped part and is installed in the cutout of the body 2 along the ball supply line directly opposite the ball position in the charging chamber on the line of refilling into the barrel bore. The lever is mounted on axis 3 with the possibility of rotation relative to it. The lever may have, depending on the implementation, a different width of the main shoulder (Fig. 6). The axis of the lever 3 (Fig. 5) is designed for its fastening, while providing a given mobility. The lever axis 3 is rigidly fixed in the marker body. The spring of the lever 4 is mounted on the guide shaft 3 and provides the force that holds this lever in the neutral lock position. Operating principle.

Initial position. Neutral position of the lock lever (Fig. 5). The main arm 8 of the lever 1 enters the cutout in the housing 2 and does not protrude beyond its upper border, thereby not preventing the free movement of the bolt carrier 6, to which the bolt 5 is rigidly connected. At the same time, this position visually signals the locking position. In parallel with this, the auxiliary arm 9 enters the cutout in the housing 2 directly in front of the window for feeding the ball into the charging chamber and partially overlaps it with the lower curly protrusion 10. This position of the lever 1 is ensured by the spring 4 located in the cutout of the housing 2 on the axis of the lever 3. At one end it abuts against the wall of the cutout in the housing 2, the other affects the main arm 8. appropriate width, prevent it from moving along axis 3.

At the moment of attaching the magazine, the balls are fed into the marker under the action of its spring (Fig. 7). The first ball 7, resting against the lower curly protrusion 10 of the auxiliary shoulder 9 of the lock lever 1, due to the fact that the elastic force of the magazine spring significantly exceeds the spring force of the lock lever 4, turns it. In this case, the main arm of the lever 8 partially comes out of the cutout of the body 2, and its auxiliary arm 9 rises up and to the side until the moment when its lower curly protrusion 10 ceases to block the ball supply line. This happens due to the rotational movement of the lever 1 relative to the axis 3. After that, the ball 7 freely penetrates the charging chamber and stops on the line of sending to the barrel, at the same time ceasing its effect on the auxiliary shoulder 9. At this moment, the blocking lever 1, without experiencing more "pushing" effect of the ball, under the action of the spring 4 returns to its original position. As a result, the lower curly protrusion 10 of the auxiliary shoulder 9 again enters the cutout in the body 2 and partially overlaps the ball feed line, thereby preventing it from falling out of the charging chamber if the magazine is unfastened and the ball loses the supporting pressure of the magazine spring (Fig. 8) . The main arm 8 of the lever 1, returning again to the cutout in the body 2, signals to the player that the ball supply cycle has been performed without violations and the marker is ready to shoot.

At the moment of the shot, the bolt 5 rigidly connected to the bolt frame 6 moves forward unhindered, sending the ball 7 into the bore. After the shot, the bolt frame 6 and the bolt 5 moves back. The next supplied ball rests against the lower surface of the gate 5 and does not prevent its advancement. At the moment of full opening of the feed window by the shutter 5, the balls under the action of the magazine spring begin to move upwards. The above cycle is repeated and the system is ready for the next shot.

Blocking operation in case of violation of the shot cycle (Fig. 9). In a situation where the ball 7 for one reason or another is not able to go through the entire cycle of feeding into the charging chamber, the shutter 5 is blocked by blocking the shutter frame 6, with which it is rigidly connected. Such reasons may be a technical malfunction of the magazine spring, violation of the integrity of the ball shell, contamination in the magazine, as well as in the area of the ball supply window, charging chamber, etc. At the moment when the ball 7 moves into the charging chamber, it acts on the lever 1 by rotating it on the axis 3, simultaneously lifting up the main arm 8 above the cutout in the housing 2 (Fig. 7). In turn, the main shoulder 8 stands opposite the end of the bolt carrier 6 (Fig. 9). If at this moment the bolt frame 6 with the bolt 5 rigidly attached to it starts moving forward (the beginning of the shot process), ahead of the completion of the ball supply cycle 7 from the magazine (incomplete access to the refilling line), then the bolt frame 6 with its front end will rest against the main shoulder 8 and stop its movement, not allowing the shutter 5 to cause a destructive effect on the shell of the underfilled ball and thereby destroy it.

To continue shooting, the player must manually cock the bolt carrier 6 back and eliminate the cause of the blocking operation. The operation of the lock when shooting the last ball in the store (Fig. 10). With the shooting of the last ball fed from the magazine, the bolt frame 6 with the bolt 5 rigidly fixed on it, completing the cycle, moves back and opens the charging chamber. At this moment, the feeder 11 located at the end of the magazine spring partially enters the ball feed window. As in the above-described version with the ball 7, the feeder 11 acts on the lower curly protrusion 10 of the auxiliary arm 9, thereby turning the lever 1 on the axis 3 and raising the main arm 8 above the cutout in the body 2. In the case of a new shot (or continuation shooting in the "automatic fire" mode), the bolt carrier rests against the main shoulder 8 and stops its movement, thereby preventing dry firing and signaling the emptying of the store.

To continue shooting, the player needs to change the magazine to full and manually cock the bolt carrier 6.

The marker shutter blocking device in case of violation of the shot cycle is intended for use in markers for the game "paintball" to prevent the ball from splitting by the shutter when it is not fed to the firing line, as well as to prevent dry firing when the magazine is empty, containing a lever installed in the cutout of the marker body opposite the position a ball fed into the charging chamber on an axis rigidly fixed in the marker body, with the ability to rotate relative to it and, under the action of the elastic force of the spring acting on it with its shoulder, enter the internal space of the charging chamber, occupying a position corresponding to unlocking (the possibility of firing a shot) and hold the ball on the firing line, and under the action of the magazine spring, the elastic force of which significantly exceeds the elastic force of the spring acting on the lever arm, through the ball fed to the firing line into the barrel bore, exit the internal space of the charging chamber, occupying a position corresponding to barking (not the possibility of firing), located opposite the front end of the bolt frame, blocking its forward movement, characterized in that this lever is located across the longitudinal axis of the bore along the line of supply of balls.
