Extractor for revolver

The invention relates to an extractor for a revolver. The extractor serves the cartridges or cartridge cases from the barrel of a revolver

hinauszubefördern.

Revolvers are firearms in which the cartridges are arranged in individual cartridge chambers in a cartridge chamber designed as a rotatable drum. At the same time, the drum also serves as a magazine.

The rotation of the drum allows the cartridges to be aligned one after the other with the revolver.

Extractors for revolvers are known in different versions.

For example, US Pat. No. 4,543,741 A discloses a revolver with an extractor. An extractor mechanism for the revolver with a conventional drum includes an in

Longitudinal axis of the drum movable axis. The axis is connected to outwardly directed housing contact arms, wherein the housing contact arms are made of a slightly resilient material. The extended ends of the housing contact arms are shaped so that they protrude into a circumferential groove of the cartridge case. Thus, the cartridge or cartridge can be kept in the ignition position. Likewise, the extractor can be operated in the usual manner to convey the sleeves out of the drum.

From the document US 5341587 a further ejector with positioning mechanism is known, which should in particular enable the use of cartridges of different lengths. It is contemplated that a longitudinally extending ejector rod may be moved along its longitudinal axis relative to a central bore passage of the drum. The extractor star is connected to a spring mechanism oriented parallel to the ejector rod.

The invention has for its object to provide an extractor for a revolver, which does not weaken the drum in the region of the passage of a Auszieherstabes. The extractor should also allow positioning of the cartridges. It should Both cartridges with edge and rimless cartridges with different lengths can be used.

The invention relates to an extractor for a revolver for removing cartridges from the arranged in the drum cartridge chambers of the revolver.

The extractor according to the invention is arranged in the drum. It serves to carry out the cartridge cases remaining in the cartridge chambers after the ammunition has been fired. In this case, all cartridge casings or cartridges are ejected at the same time by moving the Auszieherstange means attached Auszieherstern. The extractors are also referred to as ejector or ejector.

The starting point of the invention is an extractor for a revolver for extracting

Cartridges of cartridge chambers arranged in the drum of the revolver. The extractor is formed by an extractor rod disposed in the hub of the drum and loaded with a spring and a multi-arm extractor star attached thereto. The extractor star with its Ausziehersternarmen extends in the radial direction to the orientation of the Auszieherstange. Furthermore, the extractor star arms have end portions corresponding to the shell of the cartridge.

According to the invention, the extractor star is designed as a flat plate and the extractor star arms of the extractor star each have a radially acting Ausziehersternarmfeder, by the end portions of the Ausziehersternarme the Ausziehersterns a movement of the Ausziehersternarme in the radial direction

Extractor bar cause.

By thus formed resilient Ausziehersternarme this can in

advantageously adapt to the relevant diameter of the respective cartridge. This means that the end sections of the extractor star arms can be pressed up to the jacket of the cartridge with rimmed cartridges or in the circumferential cartridge groove of the borderless cartridges. This can be realized in an advantageous manner, a positive contact between the Ausziehersternarmen and the cartridges. Thus, it is possible that by the movement of the extractor in the extension direction, the cartridges are conveyed out of the arranged in the drum cartridge chambers. Thus, a flexible adaptation of all Ausziehersternarme to the particular design of the cartridge used is possible in an advantageous manner.

Thus, the extractor star can advantageously be used simultaneously for different types of cartridges, since each Ausziehersternarm adapts to the respective cartridge.

Due to the planar design of the Ausziehersterns and integrated in the Ausziehersternarmen, acting in the radial direction springs no corresponding recesses must be provided in the hub of the drum in an advantageous manner. Thus, the hub of the drum is advantageously not weakened and less material must be removed from the drum.

Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.

According to an advantageous embodiment of the invention, the extractor star is made of spring steel.

The spring, hereafter called Ausziehersternarmfeder, is by each in the

Ausziehersternarme introduced cutouts realized. The cut-outs are oriented transversely to the radial direction as well as oriented transversely to the orientation of the Auszieherstange.

This leaves between the cutouts a meandering or Z-shaped portion of the Ausziehersterns, which realizes the spring effect in an advantageous manner.

The extractor star is accordingly easy to produce. There is no need to mount separate springs, including the guide. The space requirement is low and the reliability of the resilient Ausziehersternarme is high.

In a preferred embodiment of the invention, the Ausziehersternarmfeder is designed so that the spring travel of the Ausziehersternarmfeder corresponds to the depth of a peripheral to a rimless cartridge cartridge groove. This allows the end sections of the

Ausziehersternarme by the spring travel in an advantageous manner to the two relevant cartridge diameter. According to a preferred embodiment of the invention, the Auszieherstange is connected to a radially extending shutter plate, wherein the Auszieherstern is slidably mounted on the Auszieherstange, while the

Closure plate is arranged in the pull-out direction in front of the extractor star.

The closure plate is further provided with pins, each pin is associated with each one Ausziehersternarm and the pins are oriented in the withdrawal direction.

The pins are arranged such that each extractor star arm has a pin with at least one, preferably two, positioning bores located in the extractor star arm between the extractor star arm spring and the end portions of the extractor star arms

interacts.

The positioning holes are also oriented accordingly in the direction of withdrawal. The distance between each arranged in the radial direction positioning holes of a Ausziehersternarms corresponds to the depth of the circumferential cartridge groove.

As a result of the movement of the extractor bar connected to the closure plate, the pins of the closure plate are arranged in the extractor star displaceably arranged on the extractor bar over the path into the extractor star arms

Positioning holes pushed.

The preferably two locating bores advantageously permit locking of the respective extractor star arm in two positions - a first position wherein the end portions of the respective extractor star arm abut the skirt of a rimmed cartridge and a second position wherein the end portions of the extractor star arm engage the cartridge groove of a rimless one Protrude cartridge.

Thus, the resilient Ausziehersternarme can be fixed in an advantageous manner so that they are fittingly locked in a first position on the jacket of the cartridge or in a second position in the circumferential cartridge groove.

The spring travel is limited accordingly by the lock and the position of the

End sections thus adapted to the currently relevant cartridge diameter of the shell or the Kartuschennutinnendurchmessers. The spring realizes the Adjustment to the relevant diameter and the pins with the positioning holes ensure the fixation of the respective extractor star arm when moving the

Extractor star for removing the cartridge.

This advantageously prevents the extractor star arms from retracting on withdrawal due to the rounded groove of borderless cartridges and thus the cartridge would remain in the drum. In addition, it is advantageously prevented that the cartridges tilt when pulling out of the cartridge chambers.

According to an advantageous embodiment of the invention, a ratchet is connected to the Auszieherstange in the withdrawal direction after the Auszieherstern. The ratchet, as a known component of a revolver causes the rotation of the drum after actuation of the trigger in such a way that the next cartridge is brought into alignment after the shooting of a cartridge with the barrel.

According to a further preferred embodiment of the invention, the end portions of the extractor star arms are provided with a chamfer or a contour corresponding to the cartridge groove.

The chamfering of the end sections of the extractor star arms realized with the chamfer facilitates the insertion of the cartridges. The contour of the end portions preferably corresponds to the shape of the cartridge groove of a rimless cartridge, so that the positive engagement is improved and thus a safe extraction of the cartridges, even at low

Cartridge groove depth, is possible.

FIG. 1 shows a revolver known per se in a side view. The revolver comprises a rotatable drum 1 with cartridge chambers (not shown) in which the cartridges (not shown) are arranged. The cartridges can be brought into alignment with the barrel 15 by rotating the drum 1. By actuating the extractor rod 2, 7 in the withdrawal direction AR, the cartridges, that is, preferably the cartridge casings remaining after firing, can be conveyed out of the cartridge chamber of the drum 1.

The Auszieherstange 2 and the axle rod 7 (see Figures 2, 3, 6, 7) of the Auszieherstange 2 also forms the axis of rotation for the drum first

FIG. 2 shows a view of the drum 1 with the extractor star 4 from the rear side. The view is oriented counter to the withdrawal direction in the weft direction accordingly.

The Auszieherstange 2 and the axle rod 7 (see Figures 3, 6, 7) of the Auszieherstange 2 is slidably connected to the six-armed flat, plate-shaped Auszieherstern 4 on a predetermined length (see Figure 7) via a first path X1.

The Ausziehersternarme 20 of the Ausziehersterns 4, based on the Auszieherstange 2, 7 in the radial direction (R), designed to be resilient.

The extractor star arms 20 project with their end portions 16 into the cartridge chambers 17 arranged in the drum 1, in which the cartridges 18 are placed.

To realize the suspension 20 Ausfräsungen 22 are provided in the Ausziehersternarmen so that in this area the Ausziehersternarme 20 meandering

or Z-shaped. In this way, the invention Ausziehersternarmfedern 19 advantageously in the Ausziehersternarme 20 integrated (see Figure 2). Thus, the extractor star 4 from a corresponding

Spring steel plate can be easily made.

The end portions 16 of the extractor star arms 20 are urged by the extractor star arm springs 19, respectively, against the skirt of the cradled cartridges 18

or in borderless cartridges 18 in a cartridge groove 21 (see Figures 3, 6, 7) pushed.

Thus, the positive contact of the end portions 16 of the extractor star arms 20 is realized to the cartridges 18 and thus enables the ejection of the cartridges 18 in the withdrawal direction AR via the second path X2, the so-called Ausziehweg (see Figure 3).

In the Ausziehersternarme 20 of the Ausziehersterns 4 are each arranged in the radial direction R arranged positioning holes 5.

The positioning holes 5 serve to receive the pins 8 illustrated in FIGS. 3 to 7, fastened in the closure plate 3 and oriented in the withdrawal direction AR.

By the two, arranged in the radial direction R positioning holes 5, the Ausziehersternarme 20 can be locked depending on the type of cartridges 18 in two different locking positions. A first locking position corresponds to

Use of rimmed cartridges 18, wherein the end portions 16 of the

Extractor star arms 20 each abut the jacket of the cartridges 18. The second

Locking position is relevant when using rimless cartridges 18 with circumferential cartridge groove 21. Here protrude the end portions 16 of the Ausziehersternarme 20 in the circumferential cartridge groove 21 inside (see also Figures 6 and 7).

On Auszieherstern 4 a ratchet device 6 is further arranged. The

Ratchet device 6 as a separate part is shown only in a schematic diagram. The ratchet device 6 is used to rotate the drum 1, wherein the rotation is triggered by the trigger after each of the cartridge 18 is fired, so that each next cartridge 18 is aligned with the barrel 15 (see Figure 1).

3 shows a longitudinal sectional view through the drum 1 of the revolver with the attached to the Auszieherstange 2 shutter plate 3 and slidably on the Extractor bar 2 fastened Auszieherstern 4. Figures 6 and 7 show details of Figure 3, the interaction of the Verschlussplattchens 3 with the attached pins 8 and the Auszierstern 4 with each arranged in the Ausziehersternarmen 20 in the withdrawal direction AR two positioning holes 5i, 5a illustrate.

In FIG. 3, the closure plate 3, which is connected by means of thread 10 to the extractor bar 2 or to an axis bar 7 screwed to the extractor bar 2, is shown.

At rest, the shutter plate 3 in a small recess 1 1 of the

Hub region of the drum 1 is positioned.

On the Verschlussplattchen 3 oriented pins 8 are arranged in the direction of the Ausziehersternarme 20 in the withdrawal direction.

The Auszieherstange 2 is guided by the six-armed Auszieherstern 4 on the first path X1, which is slightly longer than the length of the pins 8, displaceable in the withdrawal direction AR.

According to the cartridges 18 placed in the cartridge chambers 17 of the drum 1, the end sections 16 of the extractor star arms 20 press against the jacket or into the drawer star arm springs 19, which are only shown symbolically here

Cartridge groove 21 of the respective cartridge 18.

Thus, the respective extractor star arms 20 adapt to the respectively associated cartridge 18.

The illustrations in FIGS. 3 and 6 show the idle state. The shutter plate 3 with the attached pins 8 is the Ausziehersternarmen 20 with the

Positioning holes 5i, 5a opposite.

Specifically, here the respective pin 8 of the respective outer positioning hole 5a is arranged opposite. The Ausziehersternarmfedern 19 are compressed in Figure 6. Thus, the end portions 16 of the Ausziehersternarme 20 on the jacket of the cartridge 18 and in the cartridge groove 21 (see Figure 3). In this case, a spring travel Y of the extractor star arm springs 19 in the radial direction (R) (see FIG. 7) corresponds to the withdrawal direction AR of the spacing of the two positioning bores 5i, 5a.

By operating the extractor rod 2, 7 in the withdrawal direction AR about the first path X1, the closure plate 3 is pushed against the extractor star 4, whereby the pins 8 of the closure plate 3 are pressed into one of the two positioning holes 5i, 5a of the extractor star arm 20 and thus locked become.

In Figure 7, the locked position of the extractor star arms 20 is shown. Here stand the

End portions 16 of the extractor star arms 20 in the circumferential cartridge groove 21 of a rimless cartridge 18 (see Figure 3).

In this position, the extractor star arms 20 are thus locked. The locking is done by pushing the extractor rod 2, 7 with the shutter plate 3 to the

Extractor star 4 around the first path X1, so that the pins 8 in one of

Positioning holes 5a, 5i - here in the positioning hole 5i - protrude. This is done by the lock repealing the effect of Ausziehersternarmfedern 19th

When the pins 8 protrude into the outer positioning holes 5i, the locking of the Ausziehersternarme 20 takes place in the voltage applied to the jacket of the rimmed cartridges 2 position.

The inner positioning holes 5i serve to lock the extractor star arms 20 in the groove of borderless cartridges 2. In other words, when the pins 8 in the inner

Positioning holes 5i protrude, the locking of the Ausziehersternarme 20 takes place in the groove of borderless cartridges. 2

Thus, by means of the spring travel Y of the Ausziehersternarmfedern 19 in the radial direction (R) (see Figure 7) to the withdrawal direction AR advantageously two lockable

Positions of the pins 8 guaranteed.

In other words, the two positioning holes 5a, 5i advantageously allow the locking of the respective extractor star arm 20 in two positions, one - first position - in which the end portions 16 of the respective Ausziehersternarms 20 abut the jacket of a rimmed cartridge and a - second position - in which the end sections 16 of the respective extractor star arm 20 protrude into the cartridge groove 21 of a rimless cartridge.

Subsequently, by continuing the movement around the second path X2 of

Extractor rod 2, 7 in the withdrawal direction AR, the cartridge 18 pushed out of the cartridge chamber 17 (see Figure 3).

After ejecting the cartridge 18, the Auszieherstange 2 with the

Verschlussplattchen 3 by the arranged on the Auszieherstange 2 compression spring 13 with abutment in the drum 1 in the rest position (see Figures 3 and 6) withdrawn.

Preferably, the end portions 16 of the extractor star arms 20 are chamfered to permit easy insertion of the cartridges 18 into the cartridge chamber 17. Preferably, the end portions 16 have a contour corresponding to the revolving cartridge groove 21.

In Figure 4, a shutter plate 3 is shown as a single part in side view.

The shutter plate 3 is disc-shaped. On the shutter plate 3, the pins 8 are arranged vertically standing on the outer edge, wherein each Ausziehersternarm 20, a pin 8 is associated. The pins 8 are chamfered, in particular tapered to (not shown) when pushing on the Auszieherstern easily in the positioning holes arranged there (not shown) to be pushed.
