The inserted end position with mounted on the housing of the weapon closure housing shows 4 , The lock housing is fixed in this mounted end position by means of a locking button 113 which will be explained in more detail below. It can also be seen in 4 a locking edge 114 for a locking catch, which also in the 1b and 2 is drawn. This locking edge 114 is located on the lock block 104 and protrudes through a groove 115 in the one half of the housing 101 laterally outwards.

The locking catch 98 works together with a in 4 recognizable component 97 of the magazine. This wanders up with each shot in a guide of the magazine. After the last cartridge is fired, there is the device 97 in his highest position. This will be the catch catch 98 pressed upwards in an approximately horizontal position. When the shutter 100 After the last shot has moved backwards, then prevents the catch lever 98 that is in front of the locking edge 114 of the lock housing sets the shutter to move forward again. The closure thus remains open, which represents another safety device.

The already mentioned locking button 113 for fixing the lock housing 100 in its retracted end position can be better in the enlarged detail according to the 5a and 5b detect. These figures show schematically simplified a section of the assembled closure housing and can be seen in 5a the secured position in which the spring-loaded locking button 113 behind the back edge 116 of the lock housing, which may be slightly beveled, snaps when the lock housing 100 has reached its final position. 5b shows the position for disassembly, including first in the direction transverse to the insertion direction of the closure housing against the force of the spring 117 sliding lock button 113 is pressed in, so that then the rear edge 116 of the closure housing 100 is exposed and this can be pulled out to the rear.

The following is with reference to the 6 to 8th the centering of the closure block on the running block in a weapon according to the invention explained in more detail. 6 shows the above with reference to 2 described closure block 104 , the purpose of a better centering and fixing in the housing of the weapon on the running block 118 is centered by suitable guide elements by a positive connection. The running block 118 who in 6 is shown without the barrel, preferably forms in the weapon according to the invention a structural unit with the barrel, which can be used in the preassembled state in the outer housing of the weapon and rotationally fixed by screwing the two housing halves, which is not explained in detail in the present application , The running block 118 has a ramp at its end remote from the barrel (not shown) 119 in, in the middle of a groove 120 is arranged. As in 7 can be seen, the closure block 104 on its underside one of this groove 120 associated bridge 121 on that in this groove 120 is insertable, so that a mutual determination by positive engagement and a centering of the closure block 104 results. In 8th is again shown the assembled state in a perspective view from below, in which said web 121 of the lock block 104 in the groove 120 of the running block 118 is included.

The following is with reference to the 9 to 13 the trigger mechanism with the locking catches and an additionally provided fall protection in an exemplary weapon according to the invention explained in more detail. The representation according to 9 shows schematically simplified deduction 122 , the fall protection 123 , the trigger guard 124 , the catch catch 125 , the hammer 126 , the beater bar 127 and the breaker 128 , At the hammer 126 There is a first safety catch 129 and a second locking catch 130 (please refer 10 ). 9 shows the tensioned state. The first safety catch 129 keeps the hammer cocked. If the trigger is now activated, the fall arrest becomes 123 moved backwards. The trigger guard 124 can now move backwards. The fall protection 123 thus ensures that the trigger guard moves only when the trigger is operated, and not accidentally already when the gun falls to the ground. The driver is in the direction of hammer 126 pressed and leads to a certain trigger path the trigger guard 124 With. Because of the catch catch 125 with the trigger guard 124 is connected and this is led down, is the hammer 126 from the first safety catch 129 released and jumped forward on the firing pin. This will trigger the shot. This position with from the first safety catch 129 dissolved hammer 126 is in 10 shown.

11 shows the position where the hammer is 126 has jumped forward and the locking catches of the hammer lever out of engagement with the catch catch 125 are. After release, the hammer blows back and the hammer 126 is by letting go of the trigger 122 and the spring-back of the trigger guard 124 from the catch catch 125 captured. In case of a misfire the hammer falls 126 in a secured position by the second safety catch 130 is defined and in 12 is shown. In a successful ignition, the hammer blows 126 however, back to its tense state, which in 9 is shown, in which the first locking catch 129 secures the hammer.

Out 13 , to which reference is made below, once again shows the interaction of the various components of the trigger mechanism. You can see the articulation point 123a the fall protection 123 on the trigger 122 , the trigger guard 124 , the breaker 128 with the spring provided for this purpose 128a , the catch catch 125 for which the spring 125a is provided, as well as hammer 126 and beater bar 127 , From this partially sectioned schematic representation, one can better recognize the shape of the partly in ver different levels consecutive components and their articulation points and pivot axes, so that the interaction of these components and thus the functions of the trigger mechanism described above 13 be better understood.

Hereinafter, an exemplary embodiment of a magazine fuse according to the invention with reference to the 14 and 15 described in more detail. The representation according to 14 shows the unlocked position with inserted magazine 136 , 15 shows, however, the secured position with the magazine removed from the weapon. The purpose of the magazine backup is to prevent the trigger when the magazine is removed 122 is pressed. For this purpose, security elements are provided, which when removing the magazine 136 from the weapon inevitably the trigger 122 To block.

The magazine security includes, for example, a stamped steel sheet 131 , which is installed in the handle housing. This steel sheet has a lap 132 that is against a spring 133 supported. As a result, the magazine backup always has the desire to be pressed in the direction of magazine. Will now be the magazine 136 pushed in, the magazine backup slides 131 against the spring force to the rear and gives with its safety edge 134 a pen 135 free, which is the deduction 122 is attached. Is a magazine 136 (please refer 14 ) inserted into the weapon, gives the magazine security 131 the deduction 122 free and the trigger can be pressed. Will, however, the magazine 136 removed from the weapon, then pushes the magazine backup 131 over the spring 133 forward again, thereby blocking the trigger 122 by getting the fuse edge 134 over the pen 135 push and thereby the trigger 122 blocked. The trigger can no longer be operated.

The following is with reference to the 16 to 19 an exemplary embodiment of a firing pin safety device according to the invention described in detail. The task of the firing pin safety device is to prevent a shot being fired when, for whatever reason, the firing lever unintentionally 126 (please refer 9 ) from its safety catch 129 solves. This could happen, for example, if the weapon falls in the unlocked state to the ground. It is thus achieved that a shot can only solve when the trigger is operated. Otherwise, the firing pin is always secured and can not hit the edge of the cartridge.

The 16 and 17 show the location of the firing pin 106 in the lock block 104 , in which 16 the resting state represents with secured firing pin 106 , while 17 the state when the trigger is activated 122 shows. It is a firing pin safety slider 137 intended. If the deduction 122 is pulled, pushes this firing pin safety slide 137 with the help of a seesaw 138 forward and pushes with its led front edge 137a over the hilltop 141 the firing pin safety 138 , This mechanical action causes the firing pin safety 138 which are in the closure block 104 in front of a spring 139 sits (see 18 ), is pushed backwards.

The details of the mechanism of the firing pin safety are better from the respective sectional views according to the 18 and 19 where 18 again shows the resting state with secured firing pin and 19 the situation with the trigger pulled and the free firing pin. At rest, the firing pin safety device sits 138 in an undercut 140 of the firing pin 106 , Through the firing pin safety slide 137 who is against the dome 141 the firing pin safety 138 presses, this is against the force of the spring 139 pressed in and thus transversely to the direction of movement of the firing pin 106 postponed. (see arrow in 19 ). This leaves the firing pin safety 138 the undercut 140 of the firing pin 106 and the firing pin comes free. How to get into the 18 and 19 can recognize well, has the firing pin safety 138 , which may be a rotationally symmetrical in the basic geometric shape approximately cylindrical bolt-like component, for this purpose, a recess 142 on the circumference (ring groove), so that the firing pin 106 in its free position in this recess and the displacement of the firing pin safety device in the transverse direction relative to the firing pin 106 is possible.
