Description

The invention relates to a firearm with repeating function, in particular with a forearm repeater mechanism, with a housing with a first housing part and a second housing part, the first housing part at least one barrel, a guided in the first housing part and lockable with the barrel and an axial Repeating rod mounted displaceably in the housing, and wherein the second housing part has a lock for triggering the shot.

Firearms with forearm repeater mechanisms are known for example from WO 15/116 264 A2 or DE 10 2009 051 416 A1.

In known designs of firearms with fore-end repeater mechanism, the breech can only be removed by extensive disassembly work, in some cases only with the tools required for this purpose. This makes quick and / or simple removal of the closure difficult, for example for carrying out cleaning work.

The object of the invention is to enable rapid removal of the closure from the housing.

According to the invention this is achieved in that the repeater rod is mechanically connected to the closure and / or a part of the closure, preferably a closure carrier or a closure head carrier via a releasable connection.

If the repeating rod is mechanically coupled to the closure or a part of the closure, it can be moved together with the repeating rod in the longitudinal direction of the repeating rod from an operating position to a removal position. In the removal position, the mechanical connection between the repeating rod and the lock or a part of the lock is released, whereby the lock can be removed from the housing.

Preferably, the releasable connection between the repeating rod and the closure or part of the closure is formed by a bolt. The bolt can be moved between a coupling position in which the repeating rod is mechanically coupled to the closure or part of the closure and a release position in which the repeating rod is mechanically decoupled from the closure or part of the closure. The release position can only be taken when the repeating rod and the lock are in the axial removal position. The lock can only be mechanically decoupled from the bolt and thus from the repeating rod in this axial removal position of the repeating rod. The repeater bar is mechanically decoupled from the lock only in the release position.

In one embodiment of the invention it is provided that the bolt is connected to the repeating rod via a fixed connection and that the releasable connection between the bolt and the closure or part of the closure is formed. Alternatively, it can also be provided that the bolt is connected to the closure or part of the closure via a fixed connection and that the releasable connection is formed between the bolt and the repeating rod.

The fixed connection can be formed by a non-positive, positive or material connection, the releasable connection by a non-positive or positive connection. For example, the repeating rod can be firmly connected to the bolt at its first end facing the closure by means of a screw connection. The bolt itself can engage transversely to the longitudinal axis of the repeating rod and / or transversely to the barrel axis in a recess of the closure or a part of the closure shaped according to the bolt and thus form a positive connection with the closure, which enables a mechanical coupling between the repeating rod and the closure. When the repeating rod is moved axially, the lock is thus also moved with it. The bolt can be on / 9

AT 521 383 B1 2020-01-15 Austrian patent office can be slidably guided on its side facing away from the closure and / or laterally in the first housing part in order to enable an exact and smooth sliding movement. At the same time, the guide prevents the releasable connection - for example between the bolt and the lock or part of the lock - from being released too early, that is to say when the repeating rod has not yet reached the axial removal position.

In order to enable easy removal of the closure, it is advantageous if the housing has at least one removal opening, preferably formed by the first housing part, for removing the closure, the removal opening preferably being free when the first housing part is at least partially separated from the second housing part , At least partial separation here means that the two housing parts are pivoted away from one another, folded away, moved away or moved away in another way, it being not necessary that the two housing parts be completely separated, that is to say the mechanical connection between the two housing parts is completely released. The two housing parts can, for example, be pivotally or displaceably connected to one another.

Here, exempt means that the removal opening is accessible from the outside and enables removal from the first housing part or insertion of the closure into the first housing part.

According to an embodiment of the invention it is further provided that the repeating rod in a direction transverse, that is essentially normal, to its longitudinal axis and / or to the barrel axis - preferably elastic - is deflectable or bendable into a release position in such a way that in the release position the detachable connection between the repeating rod and the lock or a part of the lock is released.

In firearms with forearm repeater function, locking the breech after supplying ammunition and closing the breech is essential for security. Otherwise there is a risk of accidentally opening the breech or partially opening the breech before or during the firing. There is a risk that the locking mechanism will no longer work and that unintentional enormous gas pressure will be released in the area of the closure, which can lead to injuries to the user. In order to avoid this, the invention further provides that the lock can be fixed by a locking slide of a locking device, the locking slide being pivotably mounted in a pivoting plane in the housing, preferably in the second housing part of the housing, between a locking position and an unlocking position, preferably the swivel plane is arranged parallel to the barrel axis.

If the loaded ammunition cannot be safely fired or it has been accidentally loaded and is to be removed from the weapon, it is necessary to release the lock manually. In order to enable a quick unlocking of the lock, if necessary, an embodiment variant according to the invention provides that the locking device can be unlocked by an unlocking device, the unlocking device having an unlocking element which is displaceably arranged in an unlocking bore of the housing along a second shift axis, preferably in the shifting plane, in particular preferably the second displacement axis is arranged normal to the first displacement axis.

It when the unlocking element has a ramp area with at least one ramp surface, which is inclined at a ramp angle between 15 ° and 75 °, preferably between 30 ° and 60 °, with respect to the second displacement axis, wherein the Locking slide has a contact area corresponding to the ramp surface with a contact edge and / or a contact surface. To unlock the locking device, the unlocking element of the unlocking device contacts the corresponding contact edge or contact surface of the locking slide of the locking device via the ramp surface such that the locking slide is pivoted from the locked position into the unlocked position by pushing the unlocking element.

In order to avoid unintentional unlocking of the closure, it is provided that

that the locking slide and / or the unlocking element are / are loaded by a restoring force in the direction of the locking position. So that the locking mechanism consisting of the locking device and the unlocking device is forced to return to the rest position after an unlocking process and the securing can take effect, the locking mechanism is permanently subjected to the restoring force in the direction of the locking position of the closure.

From the prior art it is known to release the locking of the breech by controls arranged on the side or on the underside of the firearm, the controls having to be actuated upwards. In contrast, the design of the locking device and unlocking device according to the invention enables the unlocking mechanism to be actuated laterally with a movement directed transversely to the firing direction or barrel axis.

Unlocking takes place via the ramp surface forming an inclined plane between the components. The components of the locking mechanism mutually limit their paths to the rest position formed by the locked position, whereby they align themselves. Only one attachment is required for the locking device and the unlocking device.

The invention is explained below with reference to the non-limiting figures. In it show:

Fig. 1 a firearm according to the invention in a longitudinal section in an operating position, Fig. 1a [0022] Fig.2 Figure 3 Fig. 4 Fig. 5 the detail la from Fig. 1, the firearm in longitudinal section in a release position, the firearm in longitudinal section during removal of the breech, the firearm in a section along the line IV - IV in FIG. 1 and the detail V from FIG. 4.

1 to 5 show a firearm 1 with repeating function, in particular with a fore-end repeater mechanism 2, with a housing 3 with a first housing part 3a and a second housing part 3b, the first 3a and the second housing part 3b by pivoting or moving can be at least partially separated from one another from an operating position into a maintenance position.

The first housing part 3a has at least one barrel 4, a guided in the first housing part 3a and lockable with the barrel 4 closure 5 and an axially displaceably mounted in the housing 3 repeating rod 6. The second housing part 3b contains the lock 7 for triggering the shot. The longitudinal axis 6a of the repeater rod 6 is arranged essentially parallel to the barrel axis 4a of the barrel 4. The repeater rod 4 is slidably mounted parallel to the barrel axis 4a in the first housing part 3a.

The repeater rod 6 is mechanically connected to the closure 5 or part of the closure 5, for example a closure carrier 5a - via a releasable connection 8.

Between the closure 5 and the repeating rod 6, a bolt 10 is arranged, which is connected to the repeating rod 6 non-positively, positively or materially or in a combination thereof via a fixed connection 9 and thus the movement of the repeating rod 6 on the Bolt 10 is transmitted when repeating. In the exemplary embodiment, the fixed connection 9 is formed by a screw connection 9a, which connects the bolt 10 to a first end 6b of the repeating rod 6 facing the closure 5. The bolt 10 can be mechanically connected to the closure 5 via the releasable connection 8 formed here by a positive connection 8a, in that the bolt 10 transversely, ie essentially normal to the longitudinal axis 6a of the repeating rod 6 and / or normal to the barrel axis 4a, into a recess 11 of

Closure 5 engages, which corresponds to the shape of the bolt 10. As an alternative to the interlocking connection, the bolt 10 can also be connected to the closure 5 or a closure carrier 5a via a non-positive connection, depending on the design of the closure 5.

The latch 10 has on its side facing away from the closure 5 and on both adjoining sides surfaces 10a which correspond to corresponding guide surfaces 12a, 12b on the inside of the first housing part 3a. The bolt 10 is guided on the one hand over the lateral first guide surfaces 12a when the repeating rod 6 is axially displaced in order to prevent lateral deflection. On the other hand, the second guide surface 12b facing the recess 11 prevents the closure 5 from being inadvertently uncoupled from the repeating rod 6 by the surface 10a abutting the second guide surface 12b.

1 shows the firearm 1 in the operating position A, the first housing part 6a and part of the second housing part 6b being shown. The repeating rod 6 is coupled to the closure 5 and is in the front position. The bolt 10, which is mechanically firmly connected to the repeating rod 6, is inserted into the recess 11 of the closure 5 - in the exemplary embodiment, the bolt 10 and the recess 11 form the form-fitting, releasable connection 8. The second guide surface 12b prevents the repeating rod 6 from being unintentionally uncoupled from the closure 5.

In Fig. 2, only the first housing part 3a of the firearm 1 is shown, the repeating rod 6 and the breech 5 being axially displaced into the removal position B. Previously, the first housing part 3a and the second housing part 3b were at least partially separated from one another, for example pivoted or shifted relative to one another into an open position of the housing 3. This opens up a removal opening 14 of the first housing part 3a.

In this removal position B, the latch 10 has moved out of the first housing part 3a. The surface 10a has moved in the axial direction - that is to say in the direction of the longitudinal axis 6a of the repeater rod 6 or the running axis 4a - beyond the guide surfaces 12a, 12b and is thus normally exposed to the longitudinal axis 6a or normal to the running axis 4a. The bolt 10 can thus be moved out of the recess 11 in a direction normal to the longitudinal axis 6a or the running axis 4a and the releasable connection 8 can thus be released. Since, in the exemplary embodiment shown, the bolt 10 is firmly connected to the repeating rod 6 at the first end 6b via the screw connection 9a, the repeating rod 6 must be bent elastically away from the closure 5 into a release position C in order to move the bolt 10 completely out of the recess 11 and to release the positive connection 8. Reference number 13 denotes the bending angle of the repeating rod 6 in the release position C. The closure 5 can now be pulled out of the first housing part 3a in the direction of the running axis 4a or the longitudinal axis 6a of the repeating rod 6 through the removal opening 14, as shown in FIG. 3.

The installation of the closure 5 is carried out analogously in the reverse direction and sequence. FIGS. 4 and 5 show a locking device 20 for the closure 5. The locking device 20 provided for security reasons fixes the closure 5 in its axial position and serves to lock the breech 5 after ammunition has been supplied in order to prevent inadvertent opening or partial opening of the breech 5 before or during the firing of the shot. The locking device 20, which has, for example, a rotatable locking slide 21, is held in its locking position shown in FIGS. 1, 4 and 5 by a restoring force formed by a locking spring which cannot be seen. The locking slide 21 is in a pivoting plane ε formed essentially parallel to the running axis 4a about an axis of rotation 21a in a guide channel 22 of the second housing part 3b of the housing 3 between a locking position shown in FIGS. 1, 1a, 4 and 5 and a position not shown Unlocked position pivoted. In the locked position

AT 521 383 B1 2020-01-15 Austrian patent office blocked the axial displacement movement of the closure 5 in the first housing part 3a by a stop surface 5c of the closure 5 interacting with a locking surface 26 of the locking slide 21 and released in the unlocked position (FIG. 1a).

Characterized in that the locking device 20 is held in the locking position by the restoring force of the locking spring, malfunctions of the locking device 20 can be largely excluded. In particular, an unintentional deactivation of the locking device 20 can be prevented. In order to be able to safely and quickly release the lock 5 by the locking device 20 when necessary, for example, if the loaded ammunition cannot be safely fired or has been accidentally loaded - an unlocking device 30 is provided with which the lock 5 can be unlocked. The unlocking device 30 has, for example, a rotationally symmetrical - for example peg-shaped - unlocking element 31 with a ramp area 32, which unlocking element 31 is mounted in an unlocking bore 33 in the second housing part 3b in a manner that is normal to the swiveling plane ε of the locking device 20, along a displacement axis 33a. The ramp area 32 has at least one ramp surface 34 which is inclined at a ramp angle α with respect to the displacement axis 33a, the ramp angle α being, for example, between 15 ° and 75 °, preferably between 30 ° and 60 ° - in the exemplary embodiment approximately 45 ° - is. The locking slide 21 of the locking device 20 has a contact area 25, which corresponds to the ramp surface 34 of the unlocking device 30, with a contact edge 24 with a chamfer 23, which forms an angle β> = 0, for example 10 °, with the ramp surface 34. The unlocking element 31 is held in the locking position shown in FIGS. 1, 1a, 4 and 5 by a restoring force. The restoring force can be applied to the unlocking element 31 by the locking spring via the locking slide 21 and the ramp surface 34, or else by a separate return spring (not shown further).

By pressing the locking element 31 this is moved parallel to the axis of displacement 33a and pivoted via the ramp surface 34 of the locking slide 21 along the pivot plane ε against the restoring force into the unlocking position, as indicated by the arrow P in FIGS. 1 and 1a. The displacement axis 33a is arranged inclined at an angle γ of, for example, 90 ° with respect to the pivot plane ε. The closure 5 is thus unlocked and can be displaced in the first housing part 3a in its longitudinal direction, that is to say parallel to the barrel axis 4a of the barrel 4.

As shown in Fig. 1a, the closure 5 has a stop surface 5c, which cooperates with a locking surface 26 of the locking slide 21. The design is designed in such a way that the resulting force vectors act upon the locking slide 21 against the unlocking direction P when attempting to open the closure 5. As a result, the locking device 20 is self-locking when force is applied.

In contrast to known designs, the unlocking element 31 can be actuated laterally with a movement directed transversely to the firing direction or transversely to the barrel axis 4a and the shutter 5 can be unlocked in this way. Unlocking takes place via the ramp surface 34 and the contact edge 24. The components of the mechanism mutually limit their paths to the rest position and align themselves automatically. It is only necessary to attach the components of the locking device 20 and the unlocking device 30. So that the locking device 20 and the unlocking device 30 can forcibly return to the rest position after actuation and the securing can act, a restoring force acts permanently on the locking position.

The invention can be applied to a wide variety of firearms 1 with repeating function, in particular to firearms 1 with fore-end repeater mechanism 2, regardless of caliber, condition as a long or short weapon, type of breech or ammunition feed.

The invention enables a simple and quick removal of the closure 5 without the need to use any tools.
