Definitions

  • the invention relates to a repeating device for a firing device of a barrel weapon according to the preamble of patent claim 1.
  • Such a repeating device is known from DE-PS 27 50 957.
  • the stroke of a bolt for triggering the firing process of a pipe-side ignition device takes place continuously and positively during a 90 ° rotation of a firing shaft by means of a deflecting body having a control curve, which is displaced in the axial direction by a roller moving about the axis of the repeating device.
  • the firing shaft is rotated by less than 90 ° via a firing handle, that a support of a firing pin belonging to the pipe-side ignition device is partially canceled due to the positive lifting movement of the firing pin. This can lead to an unstable condition for securing the firing pin, whereby an unwanted firing cannot possibly be ruled out due to vibrations. Such firing could not be prevented by the personnel either, because the firing pin's support is not visible to them.
  • the object of the invention is to provide a repeating device in which the stroke of the trigger pin to remove the securing of the firing pin of a pipe-side ignition device can only take place at the time when the firing shaft of the repeating device actuated by a firing handle handles the actual "firing position" for triggering the Ignition device, for example after a 90 ° turn, has taken.
  • the invention advantageously ensures that the firing pin of an ignition device remains 100 percent assumed until the time a desired shot is triggered.
  • An unstable state of support for the firing pin is avoided by the fact that during actuation of a firing handle that takes place within the swiveling range of a firing shaft of the repeating device to be fired, the triggering bolt of the repeating device cannot trigger the triggering stroke because it is pushed back into the repeating device during this time.
  • the release stroke of the release pin is triggered in a particularly advantageous manner only at the end of the pivoting movement of the firing handle in the "firing position" because a first body rotatable by the fire shaft is pushed back against a first spring by a sawtooth profile arranged on the side of the release pin and thereby one Within the first body and the firing shaft, axially displaceable and connected to the release bolt, the second body opens the possibility of sliding axially backwards into the repeating device under the force of a second spring, which is weaker and acts counter to it, but when the firing position is reached and a departure of the support of the first body which is only possible at this point in time, by suddenly snapping into the next tooth of the sawtooth profile under the spring action of the first spring, to accelerate the second body in such a way that it supports the R Overcomes the return stroke and, in addition, executes the forward-facing stroke of the trigger pin to release the firing pin based on its kinetic energy.
  • the second spring pushes the release bolt and the second body back into their starting position immediately after a release stroke has taken place.
  • the second spring is further dimensioned such that the second body located in the starting position is securely positioned, as a result of which movement of the second body, for example due to external disturbing influences such as vibrations and lateral movements of a gun barrel cradle, cannot take effect.
  • the repeating device 1 shown in FIG. 1 belongs to a barrel weapon shown in DE-PS 27 50 957 and is mounted on a lower mount in the manner described there.
  • a firing shaft 2 is arranged on a side facing away from the weapon barrel, on which a lever 33 shown in FIG. 4 is positively attached to transmit a direction of rotation pointing in the circumferential direction 6.1 and is connected via a linkage 34 to a manual release lever 35 .
  • the manual release lever 35 can be pivoted in a manner known per se about an axis of a leveling wheel 36, not shown in detail and also arranged on the lower mount, in a direction of rotation 6.3 and can be pivoted back automatically via a return spring 37 (not shown). So that the lever 33 transmits only the pivoting movement of the manual release lever 35 in the direction of rotation 6.3 to the firing shaft 2, the head 38 of the lever 33 fastened on the firing shaft 2 is designed as a ratchet (not shown).
  • the repeating device 1 for triggering a firing pin 39 shown in FIGS. 4 and 5 contains a displaceably arranged bolt 4 on its longitudinal axis 7.
  • the transmission of the bolt going in the direction 3.1 of the weapon barrel Deflection 3 of the trigger pin 4 for triggering the firing pin 39 takes place on a transmission chain arranged on the side of the weapon barrel and shown in FIG. 4, which essentially consists of known means, for example from a transmission lever 40, a transmission shaft 41, a push rod 42, a rocker arm rod 43, one Rocker arm 44 and a catch pin 45 for catching or placing a catch stud 46 of the firing pin 39.
  • the transmission lever 40 rotates the transmission shaft 41 in the direction of rotation 41.1, while it moves the push rod 42 in the direction 42.1 parallel to the stroke direction 3.1 via known transmission means and the push rod 42 via an angle lever 47 the rocker arm rod 43 in the direction of 43.1.
  • the rocker arm 44 is moved downward in the direction 45.1 about a pivot axis 48 to trigger the catch bolt 45.
  • the safety pin 45 leaves the securing of the safety stud 46, so that, for example, under the force of a spring 49 tensioned by a known return stroke device 58, the firing pin 39 triggers the stroke in the direction 39.1 to fire an ammunition (not shown) in the cargo space of the weapon barrel can.
  • the firing shaft 2 has preferably been provided with a square profile 52 for attaching the lever 33 outside the housing 9 and is mounted in bearings 31 in a known cylindrical area in an adjoining and arranged inside the housing and in one further via the bearings 53 in the interior of the housing protruding area formed as a shaft end 54 on which a multi-spline 22 shown in FIG. 3 is arranged for transmitting the rotary movement to a first body 5.
  • the first body 5 has, within a bore 23, a groove profile which is coordinated with the multi-spline profile 22, as a result of which the first body 5 is positively connected to the shaft 2 in the circumferential direction 6.1 and is displaceably mounted on the shaft 2 in the axis-parallel direction 6.2.
  • the first body 5 For its axial displacement, the first body 5 contains a toothing 8 shown in FIG. 2 and arranged in a ring-like manner perpendicular to the central axis 7 and pointing towards the bolt 4, which under the force of a first spring 12 on one on the side 14 of the bolt 4 on Fixed housing 9 of the device 1 and also has a ring-like toothing disc 11 slidably abuts.
  • the teeth 8, 10 arranged on the first body 5 and on the disk 11 each consist of a sawtooth profile 24 shown in FIG. 2, which, in order to generate a backward movement of the first body 5 around the stroke 18, inclined sloping surfaces 25, 26 in the circumferential direction 6.3 and contains ratchet surfaces 27, 28 running parallel to the axis of rotation 7.
  • the sliding surfaces 25, 26 and ratchet surfaces 27, 28 preferably form four profile teeth 24 which are arranged uniformly distributed over the circumference, so that after rotation of the body 5 in the circumferential direction 6.1, for example 90 °, the body 5 extends by the stroke 18 of a tooth height from the disk 11 lifts off, while if there is no support of its sliding surface 25 through the sliding surface 26 of the disk 11 fixedly arranged on the housing 9, it suddenly moves back by the same stroke 18 under the biasing force of the first spring 12.
  • the first body 5 contains on its side facing away from the toothing 8 an annular groove 29 for receiving the first spring 12, which is designed as a compression spring and is supported on an axial bearing relative to the housing 9 to ensure rotation.
  • a second body 13 connected to the bolt 4 is arranged axially displaceably, which in the rest position of the device 1 and during an initial stroke range 15 of the first body 5 under the force of one on the front side 14 on the housing 9 supporting second spring 19 abuts a stop 16 of the first body 5 and remains in a remaining loading area of the total stroke 18 at an end stop 17 of the firing shaft 2.
  • the substantially likewise cylindrical second body 13 has a projection 51 which projects in the radial direction and serves on the other side to support the second spring 19.
  • the shaft of the second body 13 contains a stop 20 directed towards the bolt 4, which consists of a shoulder and at a distance 21 corresponding to the deflection 3 relative to the inner surface of one on the side 14 located wall of the housing 9 is arranged.
  • the second body 13 contains a cylindrical extension 32 that is axially displaceable within the firing shaft 2.
  • the firing shaft 2 contains a correspondingly adapted bore 31 to accommodate the extension 32, which extends essentially over the entire length of the firing shaft 2 and is offset several times.
  • the mass of the second body 13 has been increased by the extension 32, the amount is smaller than the mass of the first body 5 and is thus coordinated with it and with the biasing force of the first compression spring 12 and the second compression spring 13, which is also designed as a compression spring, but acts in opposite fashion, wherein the biasing force of the first compression spring exceeds that of the second compression spring, so that the second body 13 after reaching the maximum compression stroke 18 of the first spring 12 and after leaving the support provided by the teeth 10 of the first body 5 and after by the first spring Acceleration of the first body 5 in the stroke region 18 and the second body 13 in the partial region 15 of the stroke 18 takes place by bridging the additional distance 21 to achieve the deflection 3 of the release bolt 4 solely on the basis of the kinetic energy of the second body 13 and with its stop 20 on the wall of the housing 9 comes to rest.
  • the housing 9 of the repeating device 1 consists of a plurality of parts which can be screwed together, the firing shaft and the first spring 12 being mounted in a rear housing part 52, while a cover 57 located on the front side 14, to which the Washer 11 is connected via screws, not shown.
  • the external dimensions of the repeating device match the repeating devices of barrel weapons already introduced by the troops, e.g. for field howitzers 70, agree, which allows easy interchangeability and a significant increase in operating safety can be achieved.
