Description

Repeater Rifle {DEVICE FOR LOCKING A CLOSURE IN A REPEATING WEAPON}

The present invention relates to a repeater rifle having an action capable of moving in a firing direction, that is, a longitudinal direction, wherein the interlocking block is capable of moving laterally with respect to this action and being introduced into the recess of the action and the rifle body to lock the action. And a repeater rifle having a steering device for moving the action forward and backward and introducing and releasing the interlocking block (preamble of claim 1).

Position or direction indications such as "from above" or "forwardly" herein refer to the rifle in the normal shooting position, ie the position of shooting "horizontally" horizontally.

Immediately after the invention of the repeater with bolt action, attempts were made to simplify the procedure and operation required to charge the rifle. Until then, in order to charge the rifle, the shooter had to perform lateral motion, rearward motion, forward motion and again lateral motion. Therefore, manufacturers have introduced a kind of screw drive that has transformed the previous complex sequence of operations into simple rear and front movements. However, due to its complicated mechanism, these so-called "straight-pull" systems were either unreliable or overly expensive. In these known systems, the actual action is assigned to a slider that can be considered an action carrier.

Other systems exist that simplify the procedures and operations used to charge the rifle. One such system is briefly described in the preamble of claim 1, which was designed before the straight-pull system described above. The action can move straight forward until it reaches the cartridge bottom of the cartridge magazine. When this action position is reached, the transverse slider or interlocking block moves into the recesses of the action and rifle bodies to lock the action. The lever pivots downward in an arcuate motion to release the interlocking block on the initial path. After moving along the final path, the unlocked action is pulled back. The action is closed and locked only when the lever pivots upwards. Since 1895, such a system is also known as a box magazine.

Rather than using a lever, similar systems are operated by linear motion sliders connected to the front shaft. In this case, however, the interlocking block performs a turning operation.

All of the above systems are quite complex and therefore expensive and sensitive.

In the case of interlocking blocks actuated by levers or front shaft glider, high surface pressures occur, especially when accompanied by powerful cartridges. Such high pressures require a robust design or extreme manufacturing precision.

In the case of firearms used in emergencies, it is particularly important to combine a robust design with small dimensions and reliability at low cost.

After all, such firearms should be used only in rare emergencies, but they must operate safely in the reverse situation.

Summary of the Invention

The technical problem of the present invention is to further develop the above-described repeater so that at least some of the above-mentioned difficulties are at least partially removed.

Preferably, the present invention should provide a straight-pull repeater rifle which is particularly suitable for emergency use, but also suitable for military, police and similar purposes.

This technical challenge is provided with an action carrier which is capable of moving parallel to the action over the initial and final paths in the rifle described above, the action carrier being provided with at least one inclined surface that engages the corresponding surface on the interlocking block and If this inclined surface moves over the initial path, this is achieved by releasing or introducing the interlocking block (claim 1).

To some extent, the present invention utilizes the above-mentioned straight-pull action longitudinal slider known from the lever-action rifle to actuate the interlocking block. The action can be very simple, which reduces the total length of the rifle. Since the longitudinally movable action carrier does not need to be longitudinally adjacent to the action, the movement path of the action carrier need not be strictly defined, it just needs to be long enough.

The action carrier moves across the lost-motion path before moving along the initial path, during which the action remains interlocked (claim 2). This idle path not only compensates for design errors, but also allows the shooter to gain momentum. Thus, the interlocking block is unlocked only after the action carrier has gained a constant speed. This usually allows light action to lead the shooter unnoticed to such a slight breakdown.

In another preferred embodiment of the present invention, the rifle body consists of a rear end and plastic housing of the barrel or barrel restraint shell, and a recess designed in the rifle body and / or barrel restraint housing of the rear end of the barrel (claim 3). During the course of the firing, the main force is generated by the action directed into the barrel through the interlocking block. The actual rifle housing made of plastic material is parasitic only, guides the movable components and prevents all the components from being fouled.

Due to the high degree of design freedom, the rifle according to the present invention can take almost any practical form. The steering device of the action carrier may be a handle, a front shaft or a lever, or simply a grip that projects laterally, forward or backward from the (plastic) housing.

The invention also proposes that the trigger pin will be mounted directly on the action, in particular across it (claim 4).

However, if the action leans over it, the cartridge can be ignited regardless of whether the breach is interlocked or released.

To avoid this problem, another embodiment of the present invention proposes that an interlocking block is assigned to an action. The interlocking block is freely penetrated by the triggering pin in the locked position and locks the triggering pin in the withdrawn position in the unlocked position (claim 5). Thus, in some respects, the interlocking block acts as a safety bolt because the trigger can only ignite the cartridge when the action is locked.

This embodiment of the invention is characterized in that the interlocking block comprises a beveling and the triggering pin is pressed to its invalid position by the beveling while the interlocking block moves from the locked position to the unlocked position. It is further improved in (Claim 6). For example, due to a defective cartridge, if a trigger pin is caught in the ignition primer during firing, the trigger pin is loosened and released by the operation of the unlocked interlocking block to return to its invalid position.

According to another preferred embodiment of the invention, this interlocking block can move transversely with respect to the centerline of the bore from the lock position and from the lock position within the action. It also penetrates the action and engages or is rigidly connected to the recess of the component designed integrally with the barrel in the locked position (claim 7). Such engagement preferably occurs at three spots regularly distributed along the circumferential direction. This is especially true for shotguns where the size of the cartridge makes it possible for the recesses and locking pins to have large dimensions. In the section engaging the recess, the locking pin is preferably slightly inclined so that it can always be smoothly locked and unlocked (especially with large housing tolerances).

In terms of the action opposite the recess, the action carrier may be designed as a component that is moveable along the action. The interlocking block is equipped with front and rear base plates, the action carrier is equipped with front and rear drive plates,

The retracting action carrier hits the front base plate of the interlocking block with its front drive plate upon reversal, drawing it out of the recess,

The action carrier strikes the rear base plate of the interlocking block with its drive plate in the closing operation and presses it into the recess,

At least one of the front or rear base or drive plate is inclined (claim 8).

Once the action is locked, the action carrier can move forward freely past the position it takes after locking is complete. Conversely, if the action carrier moves backward from this position, after moving the particular idle path, the action carrier pulls the interlocking block from the recess and then carries the action as well. It does not matter how large the level of play between the base plate of the interlocking block and the drive plate of the action is. What is important is that the base plate fits in the opening of the action carrier formed between the drive plates.

This allows for a simple and low precision manufacturing process. In other words, inaccurate parts or spare parts can be assembled without further adjustment.

Rifles designed by the present invention can be used, for example, in small aperture repeaters. The system designed according to the invention is particularly suitable for repeater shotguns (claim 9) and preferably for front-shaft repeaters.

In general, the system of the present invention has been found to be particularly suitable for multiple-barrel rifle using large cartridges, such as cartridges of 15 mm or larger diameter, since two or more retractor claws firmly hold and guide very large cartridges.

Repeater actions may also be used with an autoloading (semi-automatic) firearm in which an autoloading mechanism (eg gas piston gear) is connected to the segmented rod instead of the grip.

In the following, the invention is described using an exemplary design and the accompanying schematic drawings.

Overall, the drawings show exemplary designs of the present invention. Accordingly, the following description will refer to individual drawings only when facilitating the location and description of particular elements / features.

The partially shown rifle is a repeater shotgun to which the box magazine can be mounted (FIGS. 1 and 2). This shotgun comprises a barrel 1 having a central axis or an axis of a bore 37. The rear end of the barrel is provided with a cartridge magazine 3, to which the end section 4 of the barrel 1 is connected. This end section 4 has a substantially “U” shaped cross section facing the bottom (FIG. 4) and comprises an upper locking recess 5 in the center and two interlocking notches 6 in the bottom. These notches are seated at the free ends of the two branches with "U" shaped cross sections. About half the height of the “U” branch is provided with a groove 10 extending parallel to the axis of the bore 37, into which the cartridge extractor 61 extends.

In a firearm ready for firing, the cartridge magazine 3 is closed by an action extending backwards. The action is penetrated by a front vertical bore hole that constrains the interlocking block 25. This interlocking block has an inverse "T" shaped cross section (FIGS. 5A and 5B) transverse to the axis of the bore and has a conical interlocking extension 7 at the free (upper) end of the central shaft, ( Lower) has interlocking fingers 8 at each of the two ends of the transverse shaft.

In the interlocked position, the interlocking extension 7 is engaged with the interlocking recess 5, while at the same time the interlocking finger 8 is engaged with the interlocking notch 6.

All the engagement surfaces are inclined relative to the vertical, in order to allow the interlocking block 25 to smoothly engage and disengage the end section 4 of the barrel 11. However, the inclination angle of the surface is so small that the engagement can self-lock, ie cannot be opened backwards by a force applied on the action 11 along the axis of the bore 37.

Thus, during firing, the barrel 1 and the action 11 are directly connected to each other, transferring the initial great force directly to each other. No factor is affected by the transfer of forces. Thus, the barrel 1 can have its rear end embedded in the plastic body 2. This fact states that the greatest force is not transmitted to the body 2.

Action 11 is seated on action carrier 13 (FIGS. 3A and 3B). This action carrier is movable longitudinally along a particular path with respect to the action. This action carrier 13 comprises a longitudinal recess 54, a transverse recess 53 in the area under the interlocking block 25 and a flat surface 59 behind the transverse recess.

In the front, the transverse recess 53 is limited by the lugs 55 on both sides of the longitudinal recess 54. These lugs project upwards and backwards and over the flat surface 59.

The interlocking block 25 is designed such that the lower surface of the transverse shaft abuts the lower surface of the action 11 in its upper interlock position (FIG. 1). In this position, the action carrier 13 can move forward and backward under the interlocking block 25, and the action 11 and the interlocking block 25 can slide on the flat surface of the action carrier 13. Can be.

However, if the action carrier 13 is moved backwards beyond the seating position shown in FIG. 1, the two lugs 55 use the rear edge to grip both sides of the transverse shaft of the interlocking block 25, It will be pulled towards the bottom into the transverse recess 53. This location is shown in FIG. In this position, the interlocking block 25 is released from the end section 4 of the barrel 11. The action 11 can now move rearward relative to the barrel 1.

Thus, the unlocked action 11 moves in a guide (not shown) of the body 2 such that the interlocking block 25 cannot move upwards during further rearward movement.

During the closing of the action 11, the action hits the rear end of the cartridge magazine 3, ie the bottom of the cartridge. The action carrier 13 is thus further pulled or pushed forward towards the spring 9 (only schematically shown in the direction of the force). A bevel 57 forming the rear wall of the transverse recess 53 presses the interlocking block 25 upwards. That is, the flat surface 59 is below the interlocking block 25 and presses it upwards during the forward movement of the interlocking block 25 until it reaches the position shown in FIG. 1.

The action 11 comprises a rotary separating block 27, generally at the rear of the interlocking block 25 and substantially parallel to its central shaft, which is held in its usual position by the latch 28 (FIG. 1, 2, 6, 8 and 9). This separating block 27 is constrained in the rear, vertical transverse bore hole 23 present in the action 11.

The interlocking block 25 and the separating block 27 are penetrated by the percussion 19, for which bores 31, 34 are formed.

The lower end of the separation block 27 is designed in the form of a T-pod 5, which extends into a longitudinal recess 54 with an inverted “T” shaped cross section in the action carrier 13. In the operating state, that is, with the T-pod located under the flank of the groove 54 and the separation block 27 held by its latch, the shoulder 35 of the cocking pin 19 is connected to the separation block ( It hits the protrusion 36 located behind it in the bore hole of 27). This prevents the trigger pin 19 in the use position from falling back to the action 11. After overcoming the latch 28, if the separation block 27 rotates about 1/8, the trigger pin 19 can be moved backwards. In this state, since the T-pod 51 is still located below the upper flank of the groove 54, the action 11 and the action carrier 13 are still joined together, while the trigger pin 19 is to be exchanged. Can be. If the separation block 27 is only a full quarter turn (this is only possible after the trigger pin 19 has been removed), the T-pod 51 will be released from the groove 54 and the action 11 will take action. It may be removed from the carrier 13.

The bore holes 31 present in the interlocking block 25 are penetrated by the triggering pins 19, and despite the presence of the triggering pins 19, the interlocking block 25 is shown in FIGS. 1 and 2 (locked state). And a deep hole for taking the position shown in the unlocked state).

Behind the deep hole 31, the trigger pin 19 includes a slug 29, with the inclined recess 33 (complementary to the slug 29) being rearward of the deep hole 31. Is designed to. The recess 33 and the percussion pin slab 29 have the perforations 31 in the perforation pin 19 only when the interlocking block 25 is at its uppermost position (the interlocking position shown in FIG. 1). It is designed to go inside. In this position, the trigger pin 19 can go deep into the deep hole 31 so that its tip protrudes from the front surface of the action 11 to ignite the cartridge.

When the interlocking block 25 is lowered (due to its special shape), the recess 33 presses the cocking pin slab 29 backward so that the cocking pin tip no longer touches the cartridge. This design ensures that the cartridge is triggered only after the action 11 is sufficiently interlocked.

As described above, the slab 29 and the shoulder 35 hold the trigger pin loosely between two distal positions, and in the unlocked state, the inclined recess 33 of the interlocking block forces the trigger pin. Withdraw Thus, the trigger pin spring is usually in an excessive state and thus does not need to be provided.

The action carrier 13 comprises a handling device 65, which is connected to the sliding front shaft. An inseparable lock can hold this handling device in the foremost position. This handling device (hence the action carrier) is moved backwards and back forwards to reload the firearm.

When the handling device 65 is pulled backwards, the action carrier 13 is thus carried. At this time, the action carrier uses the lug 55 thereof to pull the interlocking block 25 downwards and thus to draw the action 11 thereon during subsequent downward movements. In this process, the rear end of the action carrier 13 loads the hammer of the knocking mechanism (not shown) of known design and performs the charge-down operation. When the handling device 65 is pushed forward, the interlocking block 25 is pressed upwards again in the manner described above and supported from the bottom by the flat top surface 59 of the action carrier 13. It is not important whether the carrier 13 is located 1 mm further forward. Thus, the resulting play does not affect.

Advantageous of the illustrated actions 11, 13 is that in the unlocked state (FIG. 2), the front surface of the action carrier 13 projects slightly above the front surface of the action 11. Thus, the cartridge can be moved upwards without the bottom thereof being caught by the cartridge extractor or any protrusion of the front surface of the action 11. Thus, actions 11 that are not burdened by this process do not tend to interlock when they are "underway."

As shown in FIG. 6, in this design, the action 11 comprises two cartridge extractors 61 positioned opposite each other (in some rare ways). Such a cartridge extractor 61 is shown enlarged in FIG. 7. As clearly shown, this includes the form of a hook with a hooked surface 63 facing rearward, which is designed to lean against the edge of the shut cartridge. This edge is rounded forward, in which the hook surface 63 is fitted. Depending on whether a cartridge extractor (not shown) is disposed on the right or left side, the cartridge casing is discarded to the left or to the right. However, when the cartridge casing is taken out, especially when the cartridge casing is taken out of a single cartridge extractor 61, it is important that no eccentric longitudinal or transverse forces are applied to the cartridge casing. This allows for very long cartridge casings to be taken out smoothly. It is only close to the end of the rear path of action in which an eccentric force acts on the cartridge casing, which causes the cartridge casing to be substantially disengaged from one or the other cartridge extractor.

In general, when switching from the right discharge to the left discharge, it is only necessary to switch the ejector. The two cartridge extractors 61 are held in place.
