Description

The present invention relates to a handgun comprising a weapon frame with a handle and a tiltable tilting forward tipping unit comprising at least two barrels.

Pistols with a tiltable tilting forward tilt are known from the prior art. For example, reference is made to the pistol Steyr model Piper M 1909. An air gun with a tilting barrel is for example in the German patent DE 574 329 described. Handy compact pistols of comparatively small design with a tipping unit with two barrels are also known (model Derringer), for example from the publications DE 199 40 998 B4 or DE 83 11 185.9 U1 ,

A handgun according to the preamble of claim 1 is made US1902702A known.

Object of the present invention is to provide a handgun of the type mentioned, which has a reduced trigger weight.

The solution to this problem provides a handgun of the type mentioned above with the features of claim 1.

Preferably, the bifunctional hammerhead unit is pivotable about an axis and during the clamping operation, the at least two hammer levers pivot together into their cocked position.

It is particularly advantageous if, according to an embodiment of the invention, the clamping operation of the hammer unit is effected by means of a component which is pivotally mounted on the Kipplaufeinheit and acts upon closing of the Kipplaufeinheit the hammer unit. This component may in particular be a displaceable tension lever plate.

In the weapon according to the invention, the otherwise necessary for the tensioning of the percussion lever unit force is applied by closing the Kipplaufs. As a result, only the force necessary for triggering must be applied during the shot at the trigger, resulting in a reduced trigger weight.

According to one embodiment of the invention of the task solution according to the invention it is provided that a slidable clamping lever plate presses in a first phase of movement when clamping the hammer unit against a protruding element, in particular a cam, an Anformung or the like of the hammer unit and this pivots in the cocked position and upon reaching the tensioned position, the clamping lever plate moves by a pivoting movement down under the protruding element and thus releases the hammer unit.

According to a preferred embodiment of the invention it is provided that a first firing pin unit of the weapon is replaceable, against an alternative second firing pin unit with approximately the same dimensions, in which the firing pin are in other positions. This makes it possible, for example, to use for the same weapon optionally different ammunition, that is, ammunition of different calibers or different types of ammunition. For example, you can use certain striker for Randzünderpatronen and other firing pin for cartridges that are applied centrally.

For a weapon according to the invention various types of ammunition come into consideration. The term handgun in the context of the present invention comprises one or both hands of a person usable, wearable on the user's body weapons, which allows a projectile charge containing at least one type of projectile selected from the group consisting of projectile, projectile, projectile, solid-state powder Projectiles and homogeneous solid state projectiles purposefully deployed at least a short distance of a few meters in a targeted, limited area. According to a preferred embodiment of the invention it is provided that the hammer unit interacts with at least one partially visible on the outside of the weapon tension level indicator and this acted in the cocked position so that it is moved to a position in which it indicates the cocked state of the weapon. For example, if the weapon has two barrels, there are preferably two such chip level indicators, so that one can see for each barrel whether the respective hammer is cocked. Preferably, at least one tension level indicator is pivotally mounted above or behind the hammer unit and is pivoted during tensioning of the hammer in an upper position.

In particular, according to an embodiment of the present invention, the hammer unit have a radial with respect to its pivotal Anformung applied during pivoting of the hammer unit a guided in a recess of the housing displaceable component which is displaced against the action of a spring force when the hammer unit in its cocked position swings. In this way it is possible to apply a high clamping force on the hammer in the cocked position while accommodating the components used for this purpose in a small space. The said displaceable component is acted upon by the spring force and directs this force on the radial Anformung order on the hammer. This displaceable component may for example be a bolt which is acted upon at about one end by the formation of the hammer unit and which acts approximately at the other end a compression spring which is compressed in the cocked position (of the hammer).

A further preferred embodiment of the invention provides that an indicator window is provided laterally on the housing of the weapon, preferably in the region of the handle, which indicates by color change or by an extendable cam, which triggers trigger lever on actuation of the trigger next.

In order to secure the hammer or the hammer in the cocked position, it is preferably provided that the hammer unit has a blocking element by means of which the hammer unit is blocked in the cocked position by a squeezing pawl cooperating with the blocking element.

The invention provides that the weapon has a tiltable forward tilting run and that the tilting mechanism is triggered by means arranged at the top in the rear of the frame of the weapon lever or a slider, which also can simultaneously serve as a sight. Advantageously, the invention provides that are clamped on the closing of the Kipplaufs the hammer, so that the trigger weight is greatly reduced because when removing only a required for triggering comparatively low force must be applied.

The invention provides that on the weapon a trigger unit comprising the trigger guard is present, which has an element which selectively acts upon actuation of the trigger one of the hammer lever associated rocker, which selectively triggers each of the hammer. This is structurally solved so that the trigger unit comprises a Stellradeinheit with at least one thumbwheel, which has at least two cams in different circumferential positions, which interact alternately with multiple successive actuation of the trigger each with a rocker and each alternately a barrel of the weapon associated hammer trigger. By such a constructive solution is on the one hand ensures that is triggered after triggering a hammer when repressing the trigger of the other hammer. In addition, one can use said Stellradeinheit to indicate to the weapon, which is the next runs fired, for example, by providing a wheel with different color surfaces, so that depending on the position of the setting wheel corresponding color surfaces are displayed in an indicator window on the housing can. After the trigger is actuated and the weapon fired, the thumbwheel rotates one angular unit so that the color area in the indicator window changes. For a weapon with two barrels, two different colored areas are sufficient, alternating on the surface of the setting wheel.

It will be initially on the FIG. 1 Referenced. The handgun shown here is a pistol 10 with a handle 14 and a Kipplaufeinheit 11, the two runs 12, 13 and is pivotable about an axis, so that the entire Kipplaufeinheit 11 can be tilted forward. The tipping of the running unit 11 is possible after a slider 15 has been pushed back and the running unit has been unlocked. The slider can be designed so that it also serves as a sight. The handle 14 of the weapon is an indicator window 16, in which one can read or feel information on the weapon, which triggers trigger lever on actuation of the trigger next. Above the handle 14, a pivotable safety lever 17 is provided on the housing of the weapon, which is in FIG. 1 in the secured position.

Further details of the weapon according to the invention are described below with reference to the Figures 2 and 3 explained. These are detail drawings and views showing the inside of the weapon in different positions of the dump. FIG. 2 shows the weapon with tipped running unit 11, wherein the clamping lever plate 18 and one of the hammer 19 are visible in the side view. It can be seen that the tipping unit 11 is pivoted about the pivot axis 20 forward, wherein the clamping lever plate 18 is pivotally mounted on the Kipplaufeinheit 11. Now, if from this tilted position of the barrel, the Kipplaufeinheit 11 is brought back into its closed starting position, this causes the clamping lever plate 18 moves in the direction of arrow backwards. The tilting unit 11 facing away from the rear end 21 of the clamping lever plate 18 presses against a mounted on the hammer 19 cam 22, which causes this hammer 19 pivots about its axis to the rear in a cocked position. The second hammer of the hammer unit is taken along and consequently pivoted about its axis also to the rear in a cocked position.

FIG. 3 shows the position in which the Kipplaufeinheit 11 is closed again, in a similar partially sectioned side view as they FIG. 2 represents. One recognizes in FIG. 3 in that the tensioning lever plate 18 pivotally connected to the tilting unit is now in an end position in which it moves under the cams 22 on the striking lever 19 and thereby releases the striking levers. This results from the fact that the clamping lever plate 18 is finally pressed down when closing the Kipplaufeinheit 11 and thereby released in the end position of the cam 22 on the hammer 19. The hammer then falls into its sear 31 and is thus held in its cocked position.

These in the Figures 2 and 3 recognizable catch 31 serves to secure the hammer 19 in the cocked position and is located approximately in an area below directly adjacent to the lower end of the percussion lever 19. Near its pivot axis, the hammer 19 has a radial reduction on the circumference, resulting in a projection 32 on the hammer, which cooperates with the aforementioned squeezing pawl 31 and as in FIG. 3 recognizes in the cocked position of the hammer 19 catching the catch and locked, the front end of the sear 31 snaps behind the projection 32 of the hammer 19 and thereby pivots upward as you can by comparison of the respective positions of the sear 31 in the Figures 2 and 3 recognizes.

Furthermore, in the Figures 2 and 3 one of the two tension level indicator 25 recognizable, which cooperates in each case with the hammer 19, wherein in FIG. 2 the untensioned state is shown and in FIG. 3 the tensioned state in which the hammer 19 engages with its upper end under the tension level indicator 25 and pushes it upwards, whereby the tension level indicator pivots about an axis 26. Depending on the position of the tension level indicator 25, of which there is one for each percussion lever of the weapon, so in the present embodiment two, you can thus visibly and noticeably determine at the back of the weapon from the outside, whether the corresponding percussion lever for the projectile this run is tense, because the tension indicator are visible and felt on the back of the weapon.

The weapon according to the invention further comprises a modular firing pin member 27, on the rear side at a distance in the vertical direction from each other, the two firing pin 28, 29 are located. The single hammer 19 may, of course, act on triggering the weapon only one of the two firing pin, which is solved in the embodiment so that the hammer 19 has in its upper part a formed by a recess face 30 which on the upper of the two firing pin 28 impinges when the hammer 19 is triggered, while the designated 29 lower of the two firing pin is perpendicular to the plane of the drawing in front of the hammer 19 and thus is not acted upon by this. This can be done in the severed position according to FIG. 2 recognize well. The in the Figures 2 and 3 shown hammer 19 is the right (in the view FIG. 2 Rear) hammer and this acts only on the upper firing pin 28, but not on the lower firing pin 29, for which a second (left) shock lever is provided in FIG. 2 not shown. Both impact levers together form the bifunctional striking unit of the weapon.

Further details of the mechanics of the weapon arise from the representation according to FIG. 4 , One recognizes the bifunctional striking lever unit which, in addition to the front striking lever 19 already described, has a second striking lever 33 located behind in the drawing includes, which as you can see to the hammer 19 is not identical. Both impact levers 19, 33 engage in one another in the transverse direction of the weapon. In the position according to FIG. 4 are both hammer 19, 33 in the rear cocked position. When the weapon is fired, only one of the impact levers moves into the front release position and acts on the corresponding firing pin, so that the respective other impact lever remains in the rear position and thus tense. In the region of their pivot axis, the impact levers 19, 33 each have radial projections 34, one of which in FIG. 4 and also in FIG. 2 is recognizable. This radial shaping of the other rear impact lever 33 is in FIG. 4 not recognizable, since it has a position which is offset in relation to the circumference of the Anformung 34 of the front percussion lever 19. The said projections 34 are for generating the spring force when tensioning the percussion lever, which is required to the hammer during the Firing the weapon at high speed abruptly to move forward.

Based on FIGS. 5, 6 and 7 , to which reference is made below, the spring mechanism acting during tensioning of the striking lever becomes clearer. It is for each hammer 19, 33 each provided in the weapon in a guide approximately vertically arranged bolt 47, 48, wherein the bolt is approximately parallel to the hammer in the untensioned position of the hammer, in the cocked position according to FIG. 6 but takes an acute angle to the hammer. In the vicinity of the pivot axis 49 in the lower region of each impact lever 19, 33 is in each case a radial Anformung 34, which is shown in the rotation of the percussion lever about its pivot axis 49 from the untensioned position FIG. 5 moved upwards (see FIG. 6 ), whereby the arranged around the bolt 47, 48 formed as a compression spring coil spring 50, 51, which is held in a recess, for example, the handle shell, compressed and thus clamped. This constructive solution makes it possible to provide a spring mechanism on a comparatively small space, the high spring force on the hammer 19, 33 in its cocked position according to FIG. 6 exerts, so that when the weapon fires the hammer 19, 33 at high speed leaps forward and hits the firing pin 28 (see also FIG. 2 .) While in the side views according to the FIGS. 5 and 6 only each of the rear hammer 33 is shown with its spring mechanism, you can in FIG. 7 recognize both impact levers 19, 33 with their respective bolts and springs.

The following is with reference to the FIGS. 8 to 15 First, the construction of the trigger mechanism of a weapon according to the invention explained in more detail. The trigger system comprises the trigger unit 37 with the trigger guard 38, which usually when firing the weapon operated with the finger and moved to the rear end of the weapon out (against the weft direction). There are in the housing of the trigger unit two adjusting wheels 39, 40 in its axial direction (axis in the transverse direction of the weapon) rotatably arranged one behind the other, each having at their circumference with each other at regular circumferential intervals arranged cams 41, 42, the function will be explained later. The first setting wheel 39 has on its side facing the outside of the weapon side each on the circumference of alternating color surfaces between ribs of a transport contour 52, which serve, via a recognizable from the outside of the weapon indicator window 16 (see FIG. 1 ) to make visible which hammer of the weapon is cocked respectively.

With the two setting wheels 39, 40 together acts a spring-mounted transport lever 43, which acts as a switch and which is mounted in the left grip of the handle 14 of the weapon as in FIG. 10 can recognize. The transport lever 43 is pivotally mounted in the housing of the weapon about an axis movable by means of the screw 71. This transport lever is acted upon by the transport contour 52 (protruding ribs or the like) of the setting wheel 39, which further rotates the connected adjusting wheel 39/40 when the trigger 37 is actuated.

The deduction unit 37 also includes as in FIG. 9 sees two shell-like half-pieces 53, 54, which together form a housing (see FIG. 8 ), in which the two interconnected adjusting wheels 39, 40 are rotatably mounted on an axis 70 and in which a parallel aligned to the weft direction pin 44 is mounted, which is the bearing for a surrounding coil spring 45, which serves when actuated of the trigger guard 38 to build up a restoring force in the weft direction, which ensures that the trigger guard moves back to its starting position after the firing of the weapon. The pin 44 is held in the housing of the weapon (see also Figures 2 and 4 ) And is guided guided in projections of the two half parts of the trigger unit 37, wherein the rear half of the housing of the trigger unit 37 in FIG. 9 designated by the reference numeral 53 and there the Anformung for the pin 44 can be seen. Characterized in that the pin 44 is held in the housing of the weapon, the spring 45 is tensioned when moving the trigger unit 37 relative to the pin 44 and thus generates the restoring force for the trigger guard 38.

The right adjusting wheel 40, which is connected via the axis 70 and the screw 75 with the left adjusting wheel 39, has on its outer rim a latching contour 72, which in conjunction with the spring in the housing of the trigger unit 37 resiliently mounted locking pin 73 only in a direction is rotatable.

This in FIG. 9 recognizable front half 54 of the housing of the trigger unit 37 has behind the area in which the two adjusting wheels 39, 40 are mounted to its rear end portion extending elongated extension 55, whose task is when pressing the trigger with one of two rockers 35, 36 to act together in FIG. 4 are shown. This feature will be explained later in the description of the functions of the trigger mechanism. With regard to the other structural details of the trigger unit 37 is also on the individual drawings according to the FIGS. 11 to 15 directed. In FIG. 13 one sees how the front adjusting wheel 39 is mounted in the half-part 54, while in the sectional view according to FIG. 11 the rear wheel 40 is recognizable. At the rear end of the elongated extension 55 is an upwardly directed bend 56, the function of which is to reach under the rockers 35, 36, whereby ultimately when operating the trigger guard 38 in a final phase of the taut percussion lever is released from its backup, what is best with reference to the schematic representations according to the FIGS. 16 to 19 can be explained that show the various phases of movement in operation of the trigger guard, to which reference is made below.

In FIG. 16 is the trigger guard 38 in the starting position, the illustrated here of the two hammer 19 is in its cocked rear position. The elongated extension 55 of the trigger unit with the bend 56 engages under one of the two rockers 36, so that this is pushed upward, whereby the sear 31 engages behind the projection 32 of the hammer 19 and thereby captures it in its rear cocked position. The thumbwheel 40, which has staggered cams 42 on its circumference is in an initial position.

Now the trigger guard 38, starting from the starting position to FIG. 16 a part of the way pulled back to the intermediate position according to FIG. 17 , wherein the trigger on the spring-mounted in the handle switch 43 (transport lever) slides past. The acting like a ratchet wheel 40 rotates by 60 ° counterclockwise and snaps into its next position. One can see the rotation of the thumbwheel 40 by comparing FIG. 17 With FIG. 16 recognize well. The bend 56 is still under the rocker 36. The latter has in its rear part on the underside an inclined surface 57, which acts as a ramp. In addition, the rocker 36 has a ramp 58 in its front area on the upper side. If the trigger guard 38 is then moved further backward by the remaining distance, this results in one of the cams 42 being in the area of a ramp 58 (slope). at the front end of the rocker 36 passes and pushes them down. In addition, now the bend 56 of the trigger unit enters the area of the ramp 57 and thereby the rocker 36 is released and can now pivot downwards. As a result, now the sear 31 also moves in a pivoting downward, causing them no longer blocks the projection 32 of the hammer 19 and this is therefore triggered and abruptly moves in a pivoting movement about its axis 61 forward so as to the firing pin to meet (the latter not shown here) and thus trigger a shot.

Since the same mechanism a ratchet two adjusting wheels 39, 40 comprises, for example, by 60 ° (1/6 of a complete revolution) staggered cams 41, 42 (see FIG. 9 ), there is always only one cam on the ramp 58 at the front end of a rocker 36 and triggers this while the other rocker 35 (see also FIG. 4 where both rockers are shown) is not touched by the next cam in the circumferential position and therefore remains in its position. For example, if the right rear hammer 33 (see also FIG. 7 ) is triggered in the triggering process described above and then let the trigger slide forward again, the ratchet of the trigger mechanism is the next time the trigger again rotated by a rotary unit (eg 60 °), so that is always guaranteed that then the left (front) shock lever 19 triggers.

While in the FIGS. 16 to 18 each looks in the right grip of the handle, you can see in FIG. 19 in the left grip of the handle and there detects the mounted in this handle shell serving as a switch, spring-mounted, pivotable transport lever 43 which cooperates with the ratchet of the thumbwheel 39.

In the FIGS. 20 to 22 is one for the variant of FIGS. 5 to 7 shown alternative embodiment of the spring mechanism acting during tensioning of the hammer 19. FIG. 20 shows the relaxed state of the front percussion lever 19. In this variant, a beater bar 59 which is surrounded by a coil spring 60, in the lower region near the pivot axis of the percussion lever but attached to this eccentrically on the hammer, eg riveted, in such a way that the percussion lever is pivotable relative to the beater bar. If now the hammer from the position according to FIG. 20 is stretched, then it pivots in its rear position, whereby the striker rod 59 moves in a guided movement obliquely upwards and backwards and with the coil spring tensioned. In the in FIG. 21 shown tensioned position, the spring force of this coil spring 60 acts on the hammer 19 virtually from above, So from above its pivot axis. Striker rod 59 and hammer 19 are in this tensioned position almost parallel to each other. In this construction, it is possible to accommodate the hammer assembly to a relatively small space and still achieve a large spring force acting on the hammer 19 in the cocked position. At the same time the pivot point remote from the upper end of the beater bar 59 is formed so that it pushes in its cocked position through an opening at the rear upper end of the housing of the weapon to the outside and thereby can be used as Spannstandsanzeiger, the rear outside of the weapon visible and is palpable and makes it clear which of the two striking levers is curious how to do this in FIG. 21 can recognize. The end of the shock rod 59 thus assumes in this variant a similar function as a tension level indicator as the device 25, which already on the basis of Figures 2 and 3 has been described. In the relaxed position according to FIG. 20 on the other hand, this end of the striker rod 59 is withdrawn and lies in the housing of the weapon. FIG. 22 shows once again a perspective view in which both impact levers of Schlaghebelbaugruppe with their respective percussion rods 59 and tension springs are recognizable, wherein the one hammer 19 is tensioned while the other (right rear) hammer 33 is in the untensioned position.

How to get into the FIGS. 23 and 24 recognizes, in the weapon according to the invention also a barrel lock 23 is present. In FIG. 23 is the trigger guard 38 in the front starting position while FIG. 24 shows the state upon actuation of the trigger guard, with the trigger guard 38 is in its rear position. In this rear position engages attached to the trigger unit 37 above the trigger guard Anformung 23, which serves as a running lock, in a recess 24 in the lower region of Kipplaufeinheit 11. This is used for additional fixation of the Kipplaufs during firing.

The FIGS. 25 to 27 show an alternative embodiment of the present invention, wherein it is illustrated that the firing pin unit 27 is designed variable. In this connection also on the FIGS. 2 to 4 and the above explanations refer to this. One possible design of the firing pin unit 27 is in FIG. 25 recognizable. This firing pin unit 27 is, for example, inserted in a form-fitting manner from the front into a correspondingly shaped receptacle in the upper region of the housing of the weapon. In FIG. 26 one sees the firing pin unit 27 after insertion into the housing of the weapon, being in the inserted position, for example by a in FIG. 25 recognizable pin which can be inserted in a transverse direction in a hole, can be fixed. FIG. 27 left now shows the firing pin 27 again in perspective approximately from before and one recognizes there that this unit contains two firing pins, which are arranged above or below and about one above the other. The middle picture in FIG. 27 now shows such a firing pin unit with two firing pin for central detonator ammunition, which are each denoted by the reference numeral 1. The picture on the right in FIG. 27 shows, however, the same firing pin unit, in which, however, two firing pin 2 are used for Randzünder ammunition. Here it is clear that the firing pin unit is variable due to its modular design. The basically same component can be used as a firing pin unit, where you can replace the firing pin if necessary. This is possible because of how to get in FIG. 27 In the central and right-hand illustrations, the receptacles in the firing pin unit 27 for the firing pins are shaped so that different types of firing pin can be accommodated. The basic shape of the firing pin 1 for central ignition, for example, is approximately cylindrical, while the basic shape of the firing pin 2 for edge ignition, for example, has a rectangular outline.

Claims (14)

1. A portable firearm comprising a weapon frame with a handle and a forwardly tippable break-open barrel unit comprising at least two barrels, wherein a bifunctional or multifunctional hammer unit is provided comprising at least two hammers (19, 33) movable independently of each other when triggering the firearm, wherein each hammer respectively acts upon only one firing pin of a firing pin unit comprising at least two firing pins (28, 29) arranged in spaced-apart positions, wherein each firing pin is associated with a respective barrel (12, 13) of the firearm, wherein a trigger unit (37) comprising a trigger guard (38) is provided, which has an element, which when the trigger is actuated, selectively acts upon a rocker (35, 36) associated with one of the hammers (19, 33), which rocker selectively triggers one of the hammers, respectively,
   characterised in that the trigger unit (37) comprises a setting wheel unit with at least one setting wheel (39, 40), which comprises at least two cams (41, 42) in different circumferential positions, each of which in turn cooperates with a rocker (35, 36) during multiple consecutive actuations of the trigger and each of which in turn triggers a hammer (19, 33) associated with a barrel of the firearm.
2. The portable firearm according to claim 1, characterised in that the bifunctional hammer unit is designed so as to be pivotable about an axis (61) and in that during the cocking operation the at least two hammers (19, 33) pivot together into their cocked position.
3. The portable firearm according to claim 2, characterised in that the cocking operation of the hammer unit is caused by means of a constructional element, which is pivotably attached to the break-open barrel unit (11), in particular by means of a displaceable cocking lever metal sheet (18), which acts on the hammer unit during closure of the break-open barrel unit.
4. The portable firearm according to claim 2 or 3, characterised in that in its forward area the cocking lever metal sheet (18) is pivotably attached to the break-open barrel unit (11) and in its rearward area acts upon the hammer unit, so that during closure of the break-open barrel unit the hammer unit pivots into the cocked position.
5. The portable firearm according to one of claims 1, 3 or 4, characterised in that a displaceable cocking lever metal sheet (18), in a first movement phase during cocking of the hammer unit, presses against a protruding element (22), in particular a cam or a moulding of the hammer unit, pivoting the same into the cocked position, and in that the cocking lever metal sheet (18), when reaching the cocked position, moves underneath the protruding element (22) due to a downward pivoting movement, thereby releasing the hammer unit.
6. The portable firearm according to one of claims 1 to 5, characterised in that a first firing pin unit (27) of the firearm can be exchanged against an alternative second firing pin unit of approximately the same dimensions, where the firing pins (28, 29) are in different positions or the firing pins have a different geometry.
7. The portable firearm according to one of claims 1 to 6, characterised in that the hammer unit cooperates with at least one cocked state indicator (25, 29) partially visible on the outside of the firearm and acts upon the same when in the cocked position in such a way that the same is moved into a position, in which it indicates the cocked state of the firearm.
8. The portable firearm according to claim 7, characterised in that at least two cocked state indicators (25, 59) movable independently of each other are provided, each of which is associated with one of the hammers (19, 33) respectively, and when a respective hammer is in the cocked position, its cocked state is indicated.
9. The portable firearm according to one of claims 7 or 8, characterised in that at least one cocked state indicator (25) is pivotably attached above the hammer unit and during cocking of the hammer (19) is pivoted into an upper position.
10. The portable firearm according to one of claims 2 to 9, characterised in that the hammer unit comprises a moulding (34) which is radial with respect to its pivot axis (61), which moulding during pivoting of the hammer unit acts upon a displaceable constructional element (47) guided in a recess of the housing, which element is displaced against the influence of a spring force, when the hammer unit pivots into its cocked position.
11. The portable firearm according to claim 10, characterised in that the displaceable constructional element (47) is provided as a bolt, which possibly at one end is acted upon by the moulding (34) of the hammer unit, and possibly at the other end acts upon a pressure spring (50), which is compressed in the cocked position.
12. The portable firearm according to one of claims 1 to 11, characterised in that an indicator window (16) is provided on the side of the housing of the firearm preferably in the area of a piece of the handle, which window indicates, which hammer will be triggered next on actuation of the trigger, preferably with reference to the barrels of the firearm in a differentiated form.
13. The portable firearm according to one of claims 1 to 12, characterised in that the hammer unit comprises a blocking element (32), by means which the hammer unit when in the cocked position is blocked by a sear (31) cooperating with the blocking element.
14. The portable firearm according to claim 1, characterised in that the setting wheel unit during actuation of the trigger unit (37) cooperates with a pivotable transport lever (43) and is rotated by respectively one unit of rotation.
