Description

Large caliber weapons {GAS OPERATED WEAPON}

The present invention relates to a large caliber weapon including a rear end of the barrel and a central force transmission unit in which the locking counter bearing of the launch device is accommodated (preamble of claim 1).

In the present invention, the term "large diameter" is particularly recognized to be a weapon having a maximum shell diameter or aperture of 15 mm or more.

In large caliber weapons, large missiles, such as bullets, tracers, small-shot charges, gas bodies, etc., are actually transported at very low speeds when compared to small caliber high performance weapons. Thus, the gas pressure is also relatively low, especially at the front of the barrel.

In the present invention, the description of all positions is based on the small firearm facing the firing direction and held horizontally in the standard position, the firing direction being "front".

With large diameter gas pressure equipped weapons having a cartridge diameter of more than 15 mm, the launch device is large and long and heavy, so that the force required for firing is also increased. On the other hand, since the gas pressure is low as described above, the effective range of the gas piston must be large. Thus, the amount of gas removed from the barrel during firing also increases.

For this reason, recoil loaders are preferred, which have the disadvantage of being particularly sensitive to kickback differences, as is widely accepted.

In addition, in order to lower the weight, the recent large-diameter weapons include a central anchor element on which as much force as possible is applied. Since the housing is subjected to a slight stress, it can be made of ultra-light synthetics. However, gas piston devices are typically difficult to manufacture as they require another force transfer point at the tapping point of the barrel, which acts with the gas cylinder.

In the case of designing a weapon having a normal aperture in a large size, a large diameter weapon has a disadvantage of being manufactured rather long.

Accordingly, it is an object of the present invention to develop large diameter weapons having the effect that at least one of the disadvantages of the foregoing is at least partially resolved.

In particular, it is an object of the present invention to develop automated weapons for large diameter grenades cartridges, which have a lightweight short cartridge shell and a long cartridge length which are good to load.

This object can be achieved according to the invention in which the barrel of the weapon has an opening for gas retraction at the force transmission and the gas cylinder is firmly connected to the opening for gas retraction (claim 1).

The opening for gas retraction in the force transmission portion can suppress the use of a separate power absorption bezel. At the same time, the gas pressure is sufficient to act upon the unlocking and operation of heavy launching devices with long reloading passages.

The barrel of the weapon according to the invention typically comprises a cartridge chamber designed integrally with the barrel. However, it should be appreciated that the cartridge chamber may be separate from the barrel. In the structure of the present invention, the term "barrel" includes a cartridge chamber, regardless of whether it is designed integrally with the barrel. According to the invention, the gas retracting opening is arranged at the front end of the cartridge chamber, connected to the bore hole at the force transmission and then to the front end of the gas cylinder (claim 2). The cartridge chamber is very short compared to ultra-large-caliber weapons when compared to the barrel's aperture; In the grenade cartridge of the type described above, the cartridge chamber is very short. Thus, the slow acceleration of the launch device is sufficiently made due to the effect of the launch gas to ensure that the bullet has already left the barrel before opening the launch device. Since the pressure drop in such large caliber weapons is typically very fast, the pressure in the barrel is lowered when the bullet leaves the barrel. At the same time, similar components such as tubes are not used while the high pressure in the bore holes is well accommodated to ensure the force transmission to direct the gas cylinders.

Such gas cylinders are preferably arranged in the force transmission section (claim 3), and thus do not require a separate power absorbing component.

The bore hole may be inclined to extend or extend in a direction opposite to the firing direction to take or restrain kinetic energy. Since the kinetic energy is very low at the end of the chamber, the bore hole preferably extends diagonally with respect to the firing direction (claim 4). Thus, the force transmission portion can be kept as small as possible.

Gas cylinders attached directly to the bore holes may be disposed at the bottom of the chamber or seated laterally. However, it is preferable that the gas cylinder is seated on the top of the cartridge chamber so as not to extend too far in the width direction of the weapon and also to attach the magazine to the bottom of the launch device (claim 5). Since the gas cylinder is designed as a force transmission part, a particularly small structure in the longitudinal direction can be ensured.

The launch device typically comprises a locked launcher head and launch device mount. In spite of the fact that the gas cylinder is seated at the rear, in another embodiment, the launch device may form a gas piston so that it does not use the rod system to launch device mount and also keeps the structure of the weapon short. It is proposed (claim 6).

Like the automatic rifle with a tube magazine, in which the gas piston surrounds the magazine tube, according to the invention the tube is strongly connected to the launcher mount, penetrates the gas cylinder, and penetrates like an intake tube for a reaction spring (claim 7). .

Thus, the inner surface of the gas cylinder has a circular surface, and the force operation is performed exactly in the center on the launcher mount. Since the return spring for the launch device, the so-called recoil spring, continues through the tube, the launch device mount forming the gas piston can also be correctly returned to the center. The gas cylinder can be made smaller than the required dimension as can be seen at its diameter.

According to another embodiment of the invention, the tube is for carrying a loading handle; The loading handle may be attached to the tube or used for loading, or may be connected to the tube (claim 8).

There are various locking mechanisms such as lateral locking mechanisms, locking protrusions roundly attached in the middle of the barrel, and the flaps are gripped off the middle; The protrusion is accompanied by a rearward movement of the launcher head, which increases the construction length of the weapon even finely. Therefore, according to the present invention, after the launcher bolt is penetrated diagonally through the launcher head, the launcher head is pressed from the rest position to the locked position by the launcher mounting portion, and the launcher head is locked in combination with the force transmission part (claims). 9). This embodiment is slightly circularly attached and is preferably attached symmetrically about the longitudinal axis of the barrel. Thus, the launcher head does not need to return the unlocking distance, but rather only the launcher bolt retracts diagonally with respect to the longitudinal axis. The facility for this can be arranged on top of the launcher head and does not require a structural length.

The tipping lever disposed on the launcher head is preferably formed like a device as described above. On the other hand, the tipping lever is formed in the movement passage of the launcher mounting portion or is disposed in the movement passage of the launcher bolt; When the launcher mounting portion moves out of the rest position, the launcher bolt is retracted from the forming portion of the force transmission (claim 10). This tipping lever is accommodated in a pivot axis which is arranged diagonally to the launcher head, for example. However, such a device may be manufactured with a pressure spring that presses the launcher bolt from its rest position when the launcher mount forms a space.

In addition, it is preferable that the extracted launcher bolt is coupled to the launcher mounting portion so that the launcher bolt and the launcher head move together by the movement (claim 11). Thus, an active engagement is established between the launcher head and the launcher mounting, regardless of the speed of return of the launcher mounting, ie even when loading is slow.

The launcher bolt has an elongated hole penetrated by the striker, the striker having a shoulder at the rear of the launcher bolt, the elongated hole having a taper toward the rear, thereby engaging the shoulder at the striker; When the launcher bolt is pulled out of engagement with the force transmission forming portion, it is pressed backwards. Thus, after firing, the striker is strongly pulled out of engagement with the cartridge and cannot reach the floor when the launch device is unlocked. Thus, not only the bursting trigger cap (so-called "capsule destroyer") can support the striker in front, but also early launch when the launcher head is not yet locked. Therefore, reliability can be ensured even in the case of rare dysfunction.

Typically, the launcher head includes only one extractor. In practice, however, it is known that two extractors are provided. According to the present invention, two concave portions are formed in a launcher head that is diagonal to the launcher head, and in this concave portion, one bolt hole and one forward pressure spring formed at the rear side are installed, and the bolt An extractor pivoting against a force of can be inserted into one of the recesses; The difference is that a support element which sits on the opposite side extractor and laterally supports the cartridge shell or the floor of the cartridge can be inserted into the opposite recess as required (claim 13). Thus, the extractor and the support element are arranged cross each other.

Since the support element supports the cartridge shell after extraction, the cartridge shell does not slip from the extractor teeth placed on the opposite side. After launching, the launching device first experiences an acceleration state and then a deceleration state. During this deceleration, the floor of the accelerated cartridge shell rests on the impact floor. The "impact floor" is the front face of the launcher head.

If necessary, springs and bolts on one side and support elements on the other side can be switched to change in the ejecting direction.

However, in the case of the above-described grenade cartridge, the cartridge shell is so short that it is possible to leave the cartridge chamber already in an accelerated state or just after the accelerated state.

Since the support element and the extractor are seated in recesses of the same type, they can be exchanged with each other. Therefore, since the direction of ejection of the weapon can be changed, the weapon can be adjusted for left hand shooting and right hand shooting.

Exemplary embodiments of the invention will be described in detail below with reference to the accompanying drawings.

2 is a perspective view of the launch device shown in FIG.

3 is a schematic cross-sectional view of the apparatus shown in FIG. 1;

4 is a horizontal cross sectional view of the launcher head having a cartridge rear portion;

The illustrated part belongs to a large diameter automatic rifle for a grenade cartridge, the length of which exceeds about 90 mm, but the length of the casing is 30 mm or less. The caliber is 20mm. All the figures show the same embodiment, and all the figures are given the reference numerals.

The weapon includes a barrel 101 inserted into the force transmission unit 104. The rear end of the barrel 101 forms a cartridge chamber 103. The shell casing of the cartridge 163 is housed in the cartridge chamber.

The force transmission part 104 forms a central anchor element; The anchor element may be inserted with not only a housing but also a target electronic assembly, a belt carrier, and an accessory device (a grenade launcher, a metal shotgun, etc.).

The force transmission part 104 is penetrated by a bore hole parallel to and above the mounting hole for the barrel 101, the front part having a diameter smaller than the bore hole 167 for the reaction spring tube 169 is a gas cylinder. (Or a bore hole) 171 is connected into a large bore hole. The transition between the two bore holes 167, 171 is formed to be inclined. This transition is connected to the barrel 101 through a gas retracting bore hole 173, which extends diagonally and is connected to the barrel at the end of the cartridge chamber 103.

In the two bore holes 167 and 171 described above, an integral tube is seated; This unitary tube consists of two cylindrical tube portions of different diameters, namely a rebound spring tube 169 and a gas piston (or tube) 175. The rebound spring tube 169 is movably seated, but is primarily sealed in the bore hole 167. The gas piston 175 is movably seated, but is primarily sealed in the gas cylinder 171. The shoulder between the two tubes 169, 175 forms the active surface of the gas piston 175. The gas piston 175 extends rearward as one piece by the launcher mount 113.

The movable parts from the tube 169 and the gas piston 175 and the launcher mount 113 are penetrated by bore holes that are open to the rear. The front side of the bore hole is closed. In this bore hole, the recoil spring mounting hole is seated on a recoil spring that is supported at the rear of the shown launcher arrangement, although not shown. A loading lever or loading handle is coupled to the front side (not shown) of the rebound spring tube 169, and by this loading handle the entire part 169, 175, 113 is pressed backward against the force of the rebound spring. .

When the cartridge 163 in the cartridge chamber 103 is fired, the powdered gas passes through the gas retracting bore hole 173 into the gas cylinder 171 and passes through the gas piston 175 to the above-described whole parts ( 169, 175, 113 are pressed back into the room against the force of the recoil spring.

The launcher head 111 is disposed at the rear of the barrel 101 and is disposed under the launcher mounting portion 113. It does not move alone, but may move forward and backward with the launcher mounting portion 113. The path of movement is longer than the length of the cartridge 163. The movement of the launcher head 111 is guided by longitudinal grooves or strings (not shown).

The launcher head 111 is penetrated by a launcher bolt 125 taking the form of the letter "T", the vertical beam comprising a vertical bore hole 121 in the launcher head 111. The vertical beam ends at the bottom of the launcher attachment 107. The diagonally extending "T" type horizontal beam ends on both sides of the launcher finger 108. In the middle, the horizontal beam includes a coupling protrusion 183 extending toward the rear portion.

As shown in Fig. 3, three counter bearings for the launcher bolt 125 are disposed in the force transmission 104; The lower locking counter bearing 105 has its center line on a vertical line and forms a conical bore hole passing through the center line of the barrel; Two locking counter bearings 106 are formed symmetrically about the vertical line. The locking counter bearing 106 is seated in the projection front of the inner side of the force transmission portion 104.

When the launcher bolt 125 is in the lower position as shown, i.e. in the locked position, it is engaged with the locking accessory 107 in the locking counter bearing 105, and the locking finger 108 is engaged with the locking counter bearing 106. do. The launcher head 111 is locked in close contact with the force transmission unit 104. This position is the locking position of the launcher bolt 125.

If the launcher bolt 125 is raised, the locking accessory 107 is freed from the locking recess toward the upward, and the locking finger 108 is freed from the locking counter bearing 106 upward. Now, the launcher head 111 is unlocked and can move backwards. This position is the unlocking position of the launcher bolt 125.

The striker 119 penetrates the launcher bolt 125 in the horizontal direction in the middle thereof based on the barrel 101.

To this end, the striking machine 119 penetrates the hole 131 extending from the launcher bolt 125, and thus can move without interruption between the locking position and the unlocking position.

The striker 119 includes a shoulder or inflation portion 129 at the rear as shown in FIG. In the launcher bolt 125, the rear side of the elongated hole 131 extends downward and includes a taper 133 extending upwardly and forwardly through a diagonal line. By the taper, the striker 119 is drawn into the launcher bolt 125 from the rear when placed in the shown locking position. If the launcher bolt 125 moves upward into the unlocking position, the taper 133 presses the inflation portion 129 of the striking machine 119 to press itself backwards. Thus, since the striker can only reach the foremost position when the launcher bolt 125 is placed in the locked position, the firing of the cartridge 163 can only be carried out in this position.

The spring, which is also needed by other weapons to press the striker 119 backward, is replaced by a force control that can be realized by the taper 133.

Also, in the launcher head 111, the transverse shaft 189 is disposed behind the launcher bolt 125 where the center tipping lever 187 is hinged. One leg of the tipping lever 187 grips the other leg surface from the bottom of the coupling protrusion 183 to the launcher mounting portion 113.

A locking protrusion 185 is attached to the leg facing upward of the tipping lever 187, which is attached downward and has a taper whose front side extends upwardly.

The operating modes of these facilities are as follows.

In the locked position of the launcher bolt 125 (lower position), the launcher mounting portion 113 is disposed in the foremost position (FIG. 2). Locking protrusion 185 is seated on top of launcher bolt 125 to prevent removal from the rear at this location. The position of the tipping lever 187 is shown in FIG.

If the launcher mounting portion 113 is moved backward by manual or gas pressure, the locking protrusion 185 also moves backward to release the launcher bolt 125. At the same time, the locking protrusion 185 is pivoted by moving about the vertical leg of the tipping lever 187 (clockwise in the figure). Accordingly, the horizontal leg of the tipping lever 187 pushes the coupling protrusion 183 and the launcher bolt 125 upward. Now, the upper portion is dropped on the upper leg of the tipping lever 187 to the coupling groove 191 disposed on the bottom side of the launcher mounting portion 113 in front of the taper 193, and thus remains in an inclined state. ; It is possible to maintain the launcher bolt 125 in the upper position is coupled to the groove 191. Therefore, the launcher bolt 125 and the launcher head 111 follow the rear movement of the launcher mounting portion 113. The housing fixture (not shown) is gripped at the bottom of the launcher bolt 125 from the bottom to prevent it from falling down. Thus, the connection between the parts as described above can be maintained.

When the launcher mounting portion 113 moves forward again, the launcher head 111 first strikes the rear side of the barrel 101. The locking counter bearings 106, 105 of the force transmission 104 (shown in FIG. 3) are disposed below the portions (locking fingers and locking appendages) 108, 107 of the launcher bolt 125. Now, the launcher bolt can fall down.

The downward motion is performed by the taper 193 of the locking protrusion 185 to press the launcher bolt 125 downward when the launcher bolt approaches. At the same time, since the rear side of the locking protrusion 185 releases the tipping lever 187, it can be pivoted back to the position shown in FIG. Now, the gas piston 175 integrally formed with the launcher mount 113 is moved relative to the front end of the gas cylinder 171. Launcher head 111 is now locked. Thus, the launcher bolt 125 is disposed in its lower position, and the taper 133 releases the striking machine 119.

When cartridge 163 is provided to cartridge chamber 103, the weapon is now ready to be fired.

As shown, the length of the cartridge casing 165 is equal to or less than one third of the total return of the launch devices (launcher head and launch device mount) 111, 113. This means that the cartridge casing 165 has already been completely removed from the cartridge chamber 103 before the launchers 111, 113 have been decelerated to a noticeable recoil spring. When the cartridge casing 165 is completely removed, since the barrel 101 is actually decompressed, the acceleration state of the launching devices 111 and 113 is already complete.

To support the cartridge casing 165, the top and bottom portions with the edge bridge 195 are provided with an impact floor 181 of the launcher head 111. It is more difficult to compensate for the lateral stop of the cartridge shell (or cartridge casing) 165.

4 shows a horizontal section passing through the middle of the launcher head 111. Launcher head 111 includes two slit-shaped recesses 110 symmetrically on either side, which recess extends rearward through spring bore hole 197.

An extractor tooth 161, in which a spring (not shown) in an associated spring bore hole 197 is actuated via a ram, is inserted into the one recess 110 (disposed below). The extractor teeth 161 can be pivoted about a vertical axis. The support body 199 supported by the vertical axis is generally similar to the extractor teeth 161 but cannot be moved in the recess 110 because of its size. In addition, unlike the extractor teeth 161, the support body 199 does not surround the cartridge floor of the cartridge 163 disposed in the cartridge chamber 103. When the projecting direction is changed, only the operation of switching the extractor teeth 161 with a spring for the support body 199 and the operation of switching the ejector (not shown) are necessary.
