    Description

    [0034] The invention is explained in the following in exemplary embodiments based on the corresponding drawings. They show:

    [0035] FIG. 1 a revolver in side-view,

    [0036] FIG. 2 a view of the drum with extractor star from the rear,

    [0037] FIG. 3 a longitudinal section through the drum,

    [0038] FIG. 4 a locking plate in side-view,

    [0039] FIG. 5 a locking plate from the back,

    [0040] FIG. 6 a longitudinal sectional view of the extractor star with locking plates in the rest position and

    [0041] FIG. 7 a longitudinal sectional view of the extractor star with locking plates in the second locking position.

    [0042] FIG. 1 shows a known revolver in side-view. The revolver comprises a rotating drum 1 with cartridge chambers (not shown) in which the cartridges (not shown) are arranged. The cartridges can be aligned with barrel 15 by rotating drum 1. By actuating the extractor rod 2, 7 in extraction direction AR, the cartridges, i.e. preferably the cartridge cases remaining after firing, can be conveyed out of the cartridge chamber of drum 1.

    [0043] The extractor rod 2 or the axle rod 7 (compare FIGS. 2, 3, 6, 7) of the extractor rod 2 also forms the axis of rotation for drum 1.

    [0044] FIG. 2 shows a view of drum 1 with the extractor star 4 from the rear. The view is accordingly oriented against the direction of extraction in the firing direction.

    [0045] The extractor rod 2 or the axle rod 7 (compare FIGS. 3, 6, 7) of the extractor rod 2 is connected to the six-armed flat plate-shaped extractor star 4 so that it can be moved over a pre-determined length (compare FIG. 7) via a first path X1.

    [0046] The extractor star arms 20 of the extractor star 4 are spring-loaded in radial direction (R) in relation to the extractor rod 2, 7.

    [0047] The extractor star arms 20 protrude with their end sections 16 into the cartridge chambers 17, which are arranged in drum 1 and in which the cartridges 18 are placed.

    [0048] For the realization of the suspension, the extractor star arms 20 are provided with milled recesses 22, so that the extractor star arms in this area are meander-shaped or Z-shaped. In this way, according to the invention, the extractor star arm springs 19 are advantageously integrated into the extractor star arms 20 (compare FIG. 2). Thus, the extractor star 4 can be easily manufactured from a corresponding spring steel plate.

    [0049] The end sections 16 of the extractor star arms 20 are pressed by the extractor star arm springs 19 accordingly to the casing of the rimmed cartridges 18 or, in the case of rimless cartridges 18, pushed into a cartridge groove 21 (compare FIGS. 3, 6, 7).

    [0050] This ensures positive contact between the end sections 16 of the extractor star arms 20 and the cartridges 18, thus enabling the cartridges 18 to be ejected in the extraction direction AR via the second path X2, the so-called extraction path (compare FIG. 3).

    [0051] Two positioning holes 5, arranged in radial direction R to each other, are provided in the extractor star arms 20 of the extractor star 4.

    [0052] The positioning holes 5 are used to accommodate the pins 8 shown in FIGS. 3 to 7, which are fixed in the locking plate 3 and oriented in the AR extraction direction.

    [0053] By means of the two positioning holes 5, arranged in radial direction R, the extractor star arms 20 can be locked in two different locking positions depending on the type of cartridges 18. A first locking position corresponds to the use of rimmed cartridges 18, whereby the end sections 16 of the extractor star arms 20 each rest against the casing of the cartridges 18. The second locking position is relevant when using rimless cartridges 18 with circumferential cartridge groove 21. Here the end sections 16 of the extractor star arms 20 protrude into the circumferential cartridge groove 21 (compare also FIGS. 6 and 7).

    [0054] A ratchet device 6 is also arranged on the extractor star 4. The ratchet device 6 as a separate part is only shown in a schematic diagram. The ratchet device 6 is used to rotate the drum 1, whereby the rotation is triggered by the trigger each time a cartridge 18 is fired, so that the next cartridge 18 is aligned with barrel 15 (see FIG. 1).

    [0055] FIG. 3 shows a longitudinal sectional view through the drum 1 of the revolver with the locking plate 3 attached to the extractor rod 2 and the extractor star 4 slidably attached to the extractor rod 2. FIGS. 6 and 7 show details from FIG. 3, which illustrate the interaction of the locking plate 3 with the pins 8 attached to it and the extractor star 4 with the two positioning holes 5i, 5a arranged in the extractor star arms 20 in the extraction direction AR.

    [0056] FIG. 3 shows the locking plate 3, which is connected to the extractor rod 2 by means of thread 10, or to an axle rod 7 screwed to the extractor rod 2.

    [0057] When not in use, the locking plate 3 is positioned in a small recess 11 in the hub area of drum 1.

    [0058] On the locking plate 3 there are pins 8 oriented in the direction of AR in the direction of the extractor star arms 20.

    [0059] The extractor rod 2 is guided by the six-armed extractor star 4 on the first path X1, which is slightly longer than the length of the pins 8, so that it can be moved in the extraction direction AR.

    [0060] Corresponding to the cartridges 18 placed in the cartridge chambers 17 of drum 1, the end sections 16 of the extractor star arms 20 are pressed against the casing or into the cartridge groove 21 of the respective cartridge 18 by the extractor star arm springs 19, which are only symbolically represented here.

    [0061] Thus, the respective extractor star arms 20 adapt to the respectively assigned cartridge 18.

    [0062] The illustrations in FIGS. 3 and 6 show the resting state. The locking plate 3 with the pins 8 attached to it lies opposite the extractor star arms 20 with the positioning holes 5i, 5a.

    [0063] Specifically, the respective pin 8 is arranged opposite the respective outer positioning hole 5a. The extractor star arm springs 19 are compressed in FIG. 6. Thus, the end sections 16 of the extractor star arms 20 are in contact with the casing of the cartridge 18 or in the cartridge groove 21 (compare FIG. 3).

    [0064] A spring travel distance Y of the extractor star arm springs 19 in radial direction (R) (compare FIG. 7) to the extension direction AR corresponds to the distance between the two positioning holes 5i, 5a.

    [0065] By actuating the extractor rod 2, 7 in extraction direction AR by the first distance X1, the locking plate 3 is pushed against the extractor star 4, whereby the pins 8 of the locking plate 3 are pressed into one of the two positioning holes 5i, 5a of the extractor star arm 20 each and thus locked.

    [0066] FIG. 7 shows the locked position of the extractor star arms 20. Here the end sections 16 of the extractor star arms 20 protrude into the circumferential cartridge groove 21 of a rimless cartridge 18 (compare FIG. 3).

    [0067] The extractor star arms 20 are thus locked in this position. The locking is achieved by pushing the extractor rod 2, 7 with the locking plate 3 against the extractor star 4 by the first distance X1, so that the pins 8 protrude into one of the positioning holes 5a, 5i-here into the positioning hole 5i. The locking device thus cancels the effect of the extractor star arm springs 19.

    [0068] When the pins 8 protrude into the outer positioning holes 5i, the extractor star arms 20 are locked in the position adjacent to the casing of the rimmed cartridges 2.

    [0069] The inner positioning holes 5i are used to lock the extractor star arms 20 in the groove of the rimless cartridges 2, in other words, when the pins 8 protrude into the inner positioning holes 5i, the extractor star arms 20 are locked in the groove of the rimless cartridges 2.

    [0070] Thus, by means of the spring travel distance Y of the extractor star arm springs 19 in radial direction (R) (compare FIG. 7) to the extraction direction AR, two lockable positions of the pins 8 are ensured in an advantageous way.

    [0071] In other words, the two positioning holes 5a, 5i allow the respective extractor star arm 20 to be locked in two positions, a first position in which the end sections 16 of the respective extractor star arm 20 lie against the casing of a rimmed cartridge and a second position in which the end sections 16 of the respective extractor star arm 20 project into the cartridge groove 21 of a rimless cartridge.

    [0072] Subsequently, by continuing the movement around the second path X2 of the extractor rod 2, 7 in the extraction direction AR, cartridge 18 is pushed out of cartridge chamber 17 (compare FIG. 3).

    [0073] After the cartridge 18 has been ejected, the extractor rod 2 with the locking plate 3 is retracted to the rest position (compare FIGS. 3 and 6) by the compression spring 13 with counter bearing in the drum 1, which is located on the extractor rod 2.

    [0074] Preferably the end sections 16 of the extractor star arms 20 are chamfered to allow easy insertion of the cartridges 18 into the cartridge chamber 17. Preferably the end sections 16 have a contour that corresponds to the circumferential cartridge groove 21.

    [0075] FIG. 4 shows a locking plate 3 as a single part in side-view.

    [0076] The locking plate 3 is disc-shaped. The pins 8 are arranged vertically on the outer edge of the locking plate 3, whereby each extractor star arm 20 is assigned a pin 8. The pins 8 are chamfered, in particular tapering, so that they can be easily pushed into the positioning holes (not shown) in the extractor star (not shown).

    [0077] In the middle there is a hole with internal thread 10 for fixing the locking plate 3 to the extractor rod (not shown).

    [0078] FIG. 5 shows a locking plate 3 in a single part view opposite to the pull-out direction with the pins 8 arranged at the edge.

    [0079] In the middle there is a hole with internal thread 10 for fixing the locking plate 3 to the extractor rod 2 (not shown).
