Definitions

the invention relates to a trigger device for a third-party gun, with at least one rotating weapon barrel and an inevitably moving back and forth breech, in which a spring-loaded firing pin is slidably mounted and with two movable control cams, for tensioning and releasing the firing pin for piercing a cartridge .
the known firing and safety device must function both when the rotor rotates clockwise and when it rotates counterclockwise; this results in a relatively complex construction.
the object which is to be achieved with the present invention is to create a trigger device which is as simple as possible and functions reliably.
the trigger device with which this object is achieved is characterized in that a slide provided with opposing control grooves for displacing the two control cams is displaceably arranged from a safety position into a firing or firing position.
the control slide is preferably displaceable into the firing position against the force of a spring by a hydraulic piston and its control grooves have a central, inclined section and a straight section at both ends, the central, inclined sections of the two control grooves being directed in opposite directions to one another.
FIG. 1 shows six gun barrels 11 detachably fastened in a rotor 10 in a conventional manner, only two gun barrels 11 of these six gun barrels 11 in FIG. 1 are shown.
the rotor 10 is rotatably supported in a weapon housing 13 with the aid of a bearing 12.
a breech 14 is assigned to each weapon barrel 11.
Each closure 14 is slidably mounted in the rotor 10 in longitudinal guides 15. 1 shows two locks 14, of which one lock 14 is in its foremost, locked position and the other lock 14 is in its rearmost, unlocked position.
Each closure 14 has a closure head 16 and a closure head holder 17.
the closure head 16 and the closure head holder 17 together form a rotary closure known per se, ie the closure head 16 is connected to the closure head holder 17 via a steep screw thread 18.
Cams 19 of the closure head 16 engage in recesses 20 in the rotor 10 when the closure 14 is locked in its foremost position.
the breech 14 also has a spring-loaded ignition pin 21 which, in the foremost, locked position of the breech 14, can pierce a cartridge 22 located in the weapon barrel 11.
An actuating lever or tensioning pin 29 is fastened to the ignition pin 21 and cooperates with a control cam 30 shown in FIG. 2-6. This control curve releases the firing pin 21 at the right time for piercing the cartridge 22.
a spring 34 which is supported on the one hand in the breech head holder 17 and on the other hand on the firing pin 21, tends to push the firing pin 21 against the bottom of the cartridge 22 in order to pierce and ignite the cartridge 22.
the breech 14 also has a cam roller 23 which engages in a first control cam 24 in the weapon housing 13. When the rotor 10 rotates in the weapon housing 13, this control cam 24 causes the individual breeches 14 to be pushed back and forth.
the control cam 24 is elliptical on the inside of the essentially cylindrical weapon housing 13. At the front and rear ends of the gun housing 13 are still a second bezw. third control curve 25 or 26 available, which are circular on the inside of the weapon housing 13.
FIG. 1 The weapon explained with reference to FIG. 1 is assumed to be known and is only described here to the extent necessary to understand the invention. The object of the invention will now be explained in detail with reference to FIGS. 2-6.
the control curve 30 is slidably held on a plate 31 according to FIGS. 2-4.
This plate 31 is fastened to the weapon housing 13 (FIG. 1) in a manner not shown.
the firing direction of the weapon is indicated by an arrow A in FIGS. 3 and 4.
the tip of the ignition pin 21 shown in FIG. 1 also points in this direction.
the actuating lever or tension pin 29 of the ignition pin 21 is supported on a control surface 32 of the control cam 30.
a guide groove 33 is provided in the plate 31 for guiding the control cam 30 on the plate 31.
the guide groove 33 has two rails 56 (FIG. 2) which engage in grooves in the control curve 30 and thus prevent the control curve 30 from falling out of the guide groove 33.
control cam 30 is in its foremost position, ie the spring 34 of the ignition pin 21 is only slightly tensioned when the actuating lever 29 is supported on the control surface 32 of the control cam 30.
the control cam 30 is in its rearmost position, ie the spring 34 of the firing pin 21 is tensioned and able to pierce the cartridge 22 as soon as the actuating lever 29 slides from the control surface 32 of the control cam 30 over the edge 35.
the actuating lever 29 slides on the control surface 32 of the control cam 30 in the direction of the arrow B.
a slide 36 is used to move the control cam 30 from its foremost position, according to FIG. 3, to its rearmost position, according to FIG. 4.
the control cam 30 has a bolt 37 which engages in a control groove 38 of the slide 36.
the shape of this control groove 38 can be seen in FIG.
the control groove 38 consists of three sections, a central, inclined section 39 and a straight section 40 and 41 at each end (see FIG. 5). If the bolt 37 is in the section 41, the control cam 30 is in its foremost position according to FIG. 3 and the weapon is secured because the spring 34 of the ignition pin 21 cannot be tensioned. If the bolt 37 is in the section 40, the control cam 30 is in its rearmost position according to FIG.
a driver 42 is fastened to it, which in turn is fastened to a piston rod 43.
a piston 44 which is located in a cylinder 45, is fastened to this piston rod 43.
a spring 46 which is supported on the one hand on the driver 42 and on the other hand on a guide 57 of the plate 31, has the endeavor to push the slide 36 and the piston 44 into its lowest position according to FIG. 2, in which the weapon is thus secured. With a pressure oil source, the piston 44 can be moved against the force of the spring 46, whereby the slide 36 also reaches its unlocked position.
a second control cam 47 is preferably provided for the actuating lever 29.
This second control curve 47 is slidably held on the plate 31 at both ends, just like the first control curve 30.
Two guide grooves 48 and 49 are provided in the plate 31 for guiding the second control curve 47 on the plate 31. These guide grooves 48, 49 have two rails 50 (FIG.
FIG. 3 in contrast to the first control curve 30, the second control curve 47 is in its rearmost position and prevents the ignition pin 21 from being able to pierce.
a control surface 58 of the second control curve 47 is located in the same plane as the control surface 32 of the first control curve 30.
the second control curve 47 is in its foremost position in contrast to the first control curve 30 and enables piercing in this position the cartridge 22.
the slide 36 already described is used to move the second control cam 47 from its rearmost position, as shown in FIG. 3, to its foremost position, as shown in FIG. 4.
the second control cam 47 has two bolts 51 which are in two control grooves 52 engage the slide 36.
the shape of these two control grooves 52 can be seen in FIG.
These two control grooves 52 each consist of three sections, a central, inclined section 53 and a straight section 54 and 55 at each end (see Fig. 5).
the central, inclined section 53 is inclined in the opposite direction, ie in the opposite direction to the central, inclined section 39 of the first control groove 38; this has the consequence that when the slide 36 is actuated, the first and second control cams 30 and 47 likewise shift in the opposite direction, that is to say in opposite directions, as can be seen readily from FIGS. 3 and 4.
the operation of the described device is as follows: To emit a series fire, the rotor 10 is driven by a motor and this rotor 10 with the weapon tubes 11 begins to rotate in the bearing 12 of the weapon housing 13. As a result of this rotation of the rotor 10, the breech 14 moves from its rearmost position into its frontmost position, since the roller 23 is guided in the elliptical cam 24 of the weapon housing 13. The cartridge 22 is pushed into the gun barrel 11 in the usual way and the breech head 16 is locked behind the gun barrel 11. Upon further rotation of the rotor 10, the closure 14 is unlocked again and moved back into its starting position by the control cam 24. Shortly before the closure 14 reaches its foremost position, the actuating lever 29 pushes against the control cam 30.
the actuating lever or dowel pin 29 can therefore no longer move forward together with the closure 14. As a result, the spring 34 is compressed and the firing pin 21 is moved back towards the bottom of the cartridge 22. Since the actuating lever or dowel pin 29 rotates together with the rotor 10 with respect to the weapon housing 13, while the control cam 30, which is fastened to the weapon housing, cannot rotate, the actuating lever 29 will slide over the edge 35 at the end of the control surface 32 of the control cam 30 , whereby the cartridge 22 is pierced.
