Description

Handgun and sighting device for it

The present invention relates to a sighting device for a handgun whose barrel has a muzzle thread. The invention further relates to a handgun having such a sighting device.

For handguns sights of different effects are common: In addition to riflescopes, Reflexvisie ren or night visors Kimme and grain or Di opter continue to be used as - easier - open sights.

Furthermore, handguns, especially long guns, often on the barrel have a mouth thread for screwing various ner add-on parts, e.g. a silencer, a Mündungsbrem se, a muzzle flash damper or the like. With an attached to the Mün tion grain such attachments are not compatible bar; Grain and grain grain usually carrying the grain are therefore often brought closer to the closure manufacturer, but this reduces the accuracy of sighting. Alternatively, it is known to unscrew a removable grain or an exchange grain saddle on the muzzle thread, as long as no other attachment to be screwed.

From DE 10 2015 101 455 Al a replaceable grain is known, in which screwed onto the muzzle thread a threaded nut, placed over this a grain saddle bearing ring and glued to the threaded nut. An adjustment of the grain or Kornsattel is in this case only possible as long as the adhesive is not solidified; In order to make a readjustment possible, a thermoplastic adhesive must be used, which is to be softened laboriously. If the weapon in this case warms up, e.g. in use, there is a considerable risk of unnoticed adjustment of the sights.

From US 2003/0009925 A1 or DE 20 2015 006 991 U1, on the other hand, an exchangeable grain is known, in which the grain is integrated in a ring, the ring up to the axial stop on a shoulder formed on the barrel on the mouth thread slid and secured with a threaded nut by axial pressing against the shoulder. Also in this case, the adjustment is tedious and a dangerous adjustment already at slight loosening of the threaded nut is likely.

The invention has for its object to provide a handgun and a sighting device to which is easy to use and while it is solvable and a reliable sight si cherstellt.

The object is achieved according to a first aspect of the invention with a sighting device for a handgun of the aforementioned type, whose barrel has a recess next to the muzzle thread on its surface, which sighting is characterized by the combination of a threaded nut for screwing onto the muzzle thread, a on the threaded nut anchored grain saddle with a grain and a saddle mounted on the saddle and biased towards the barrel latch for locking in the recess of the barrel when said screwing.

This sighting device is conveniently screwed onto the muzzle thread of the handgun and has thanks to the ratcheting of the latch in the recess of the barrel a reproducible aligned, secure fit on the barrel. Furthermore, the visor device is releasable due to the latch from the barrel and can thus be changed or removed.

In particular, when the recess at the top of the barrel of the handgun viewed in the direction of sight is off-center, the pawl can be mounted laterally on the grain saddle. Preferably, however, the pawl is seen in the direction of sight with tig stored inside the grain saddle. This allows a clear positioning of the pawl in the sighting device and at the same time a unique, namely central position of the Vertie tion in the barrel and thus a standardized production.

In their storage on the grain saddle, the pawl can be linearly movable be; is particularly favorable when the grain saddle has a first shaft on which the pawl is pivotally mounted. Thus, pawl and its storage are built flat and the Be operation when swinging the pawl from its in the Vertie tion of the barrel latched position simplified. Particularly advantageous before is when the pawl has an actuating arm for pivoting out of the latched position.

In a preferred embodiment, the grain saddle has a second shaft on which a grain carrier for the grain is pivotally mounted, which grain carrier has a driver for the actuating arm of the pawl. The pawl is actuated by means of the grain carrier on the grain saddle from the outside, without the need for additional actuators on the outside of the grain saddle would be required. A deflection of the eye when sighting by such actuators or the risk of entanglement of such actuators when handling the weapon thus eliminated as well. Furthermore, the pawl and its storage are protected inside the grain saddle.

It is particularly advantageous if a spring is provided between the pawl and grain carrier, which biases the pawl towards the barrel and at the same time the driver away from the actuating arm. Such a structure is space-, material- and component-saving.

It is advantageous if the grain saddle is anchored to a projecting from Außenum catch the threaded nut pin. The pin provides a rigid anchoring with rigid alignment of the grain saddle on the threaded nut thereto. Depending on the type of anchorage on the journal, the grain saddle may even be exchangeable.

It is also advantageous if the grain saddle has a sprung pressure piece for supporting against the barrel. The grain saddle and thus the sighting device thereby have a backlash-free seat on the barrel. Also, the pressure piece protects the barrel against Zerkrat zen when screwing the sighting device.

In a second aspect, the invention provides a hand firearm with a muzzle thread, which is characterized by a screwed onto the muzzle thread Visiervor direction of the aforementioned type, the run at its upper side next to the mouth thread has a recess for locking the pawl of the sighting device. In this case, the depression is preferably arranged centrally in the direction of sight at the top of the barrel. With regard to the advantages of such a Feu erwaffe is made to the preceding comments on Visiervor direction.

It is particularly advantageous if the recess is a groove extending in the direction of the visor. Such a groove, which is a win kelige depression guarantees a tight fit. If the flanks of the groove are not parallel but e. each in the radial direction of the barrel, so the flanks center the pawl in the groove and at the same time prevent inadvertent unscrewing of the pawl from the groove by turning the nut.

In an alternative embodiment, the recess is a notch extending in the direction of sighting. Such a tapered - i. V-shaped notch centers the pawl and thus the sighting device on the barrel without play. At FITS flat flank angle of the notch, the visor device can also be turned off without manual disengagement of the pawl simply by turning the nut from the recess.

The invention will be explained with reference to an embodiment shown in the beige enclosed drawings nä ago. In the drawings show:

1a and 1b show a front running end of a handgun according to the invention with a device according to the invention Visiervor without (Fig. La) or with built-in parts (Fig. Lb), depending Weil in a perspective view obliquely from the front; and

1a and 1b in a latched (Fig. 2a) and egg ner unlocked (Fig. 2b) position, each in vertical Axi alschnitt of the barrel.

Fig. La shows a section of a handgun 1, u.zw. on the side of the mouth 2 of its run 3. In this case of game, the handgun 1 is a long gun; she could ternatively be a short weapon. At its mouth 2, the barrel 3 has a mouth thread 4 (Fig. 2a) for screwing various ner attachments, such as a muffler, a Mündungsbrem se, a muzzle flash damper or the like. (not shown here).

In the example of Fig. La, a visor device 5 is screwed onto the mouth thread 4. To screw on the muzzle thread 4, the sighting device 5 comprises a threaded nut 6 and an anchored to the threaded nut 6 Kornsat tel 7 with a grain 8. In the example shown, the grain 8 - here: an optical fiber - of a grain saddle 7 gela siege Grain carrier 9 held. Alternatively, the grain 8 could be fixed di rectly on the grain saddle 7 or formed integrally therewith.

According to FIGS. 2a and 2b, the barrel 3 has, in addition to the threading thread 4 - that is to say the barrel 3. either directly after the Mün threaded thread 4 (as in the example of Figs. 2a and 2b) or in the vicinity of the mouth thread 4 - at its top a Vertie Fung 10. Further, a pawl 11 is movably mounted on the grain saddle 7, which to the run 3rd biased towards. When screwing the threaded nut 6 and thus the sighting device 5 on the mouth thread 4 of the barrel 3 locked due to their bias, the pawl 11 on reaching the recess 10 of the barrel 3 in this recess 10th

The recess 10 in the example of FIGS. 2a and 2b is a groove running in the direction of sight V, i. an in its cross-section angular recess 10. flanks of the groove can be seen in Vi sierrichtung e.g. be parallel to each other or in Ra dialrichtung of the barrel 3 to the outside obliquely auseinanderlau fen, in particular each exactly in the radial direction of the barrel 3 or even more oblique. Alternatively, the recess 10 could be a notch in the direction of sight V, i. have a V-shaped recess 10, or other cross-sectional shape, e.g. U-shape or the like.

In the example shown, the pawl 11 has a detent 12, with which the pawl 11 is latched in the recess 10. The locking lug 12 can be seen in the direction of vision V, for example, adapted to the cross section of the recess 10 down ko narrowing tapered cross section or have the same cross section as the recess 10 so that a latching of the pawl 11 in the recess 10 and maintaining the Ver. latched position of the pawl 11 are ensured safe.

Seen in the direction of sight V, for example, the pawl 11 may be laterally mounted on the grain saddle 7 and the recess 10 corresponding thereto off-center at the top of the barrel 3 are. In contrast, in the present example, the pawl 11 is mounted centrally in the interior of the grain saddle 7 as seen in the sighting direction V and at the same time the depression 10 is arranged centrally in the same direction V at the top of the barrel 3.

Further, the pawl 11 on the grain saddle 7 linearly movable

- For example, when the pawl 11 is pin-shaped, linearly movable in its Axialrich - be stored; In the example of Fig. Lb, 2a and 2b, however, the grain saddle 7 has a first shaft 13 to which the pawl 11 is pivotally mounted. In this case of game, the first wave 13 is transverse to the sighting direction V and

- In normal attitude of the handgun 1 - stored horizontally in the inside of the grain saddle 7 In neren. In this case, furthermore, the pawl 11 is a two-armed lever 14 with a latching arm 14 ¹ , on which the latching lug 12 is formed, and an actuating arm 14 "for swiveling the pawl 11 out of its latched position in the recess 10. It is understood that latching arm 14 'and actuating arm 14 "could alternatively coincide, so that the pivotally mounted pawl 11 is taken directly to the latch arm 14 ¹ actuated. Furthermore, the first shaft 13 could have another direction from or in the grain saddle 7.

The pawl 11 can be operated on the grain saddle 7, either directly on its outer side or through a lateral opening on the grain saddle 7, directly from the outside and eg on the actuating arm 14 "be operated or on the other hand operated by means of an additional control element, as explained below becomes. In the example of Fig. Lb, 2a and 2b, the grain saddle 7 has a second shaft 15, on which the grain carrier 9 is pivotally mounted. The grain carrier 9 in this example also has a driver 16 for the pawl 11. When pivoting the grain carrier 9 pushes the driver 16 (here: a on the actuating arm 14 "the pawl 11 along sliding edge of the grain carrier 9) the actuating arm 14", thereby triggers the pawl 11 from its latched position in the recess 10 (Fig. 2a) and lifts the latching nose 12 of the pawl 11 with further pressing of the grain carrier 9 finally entirely from the recess 10 out (Fig. 2b), so that the latching solved, ie the latch 11 is unlocked, and the sighting device 5 can be unscrewed from the muzzle thread 4.

As shown in Figs. 2a and 2b, between the pawl 11 and grain carrier 7, a spring 17 is tensioned, which on the one hand the pawl 11 towards the barrel 3 out, i. in the barrel 3 facing Rich, biased and on the other hand at the same time the driver 16 of the grain carrier 17 from the actuating arm 14 "of the pawl 11 away, i.e. in the direction away from the actuating arm 14" direction biased. It is understood that, alternatively, the pawl 11 and optionally the grain carrier 7 by means of e.g. each one leg spring may be independently biased or instead of such a leg spring or the spring 17 one or more other elastic elements, e.g. made of rubber, could be used, which are optionally supported elsewhere on the Visiervor device 5.

In the example of FIGS. 2a and 2b, the threaded nut has 6 ei nen projecting from its outer periphery pin 18 which is screwed to the threaded nut 6, for example, glued or welded. At the pin 18 of the grain saddle 7 is anchored, for example, e- benfalls screwed with this, glued or welded, he is - as shown in the example - locked to a circumferential groove 19 formed thereon by means of a grain saddle 7 formed collar 20. The grain saddle 7 is on anchored this way to the threaded nut 6 either releasably or non-releasably bar.

With the aid of an optional thrust piece 21 directed towards the barrel 3, the grain saddle 7 can be supported against the barrel 3. Such plungers 21 are known from the prior art, they are resiliently biased and usually have a contact surface 22 made of plastic.

The invention is not limited to the illustrated embodiments, but includes all variants, combinations and modifications that fall within the scope of the attached claims.
