Definitions

  • the present invention relates to a device for use in a mechanical servo trigger mechanism in an automatic weapon, the device being adapted to be provided on the bottom of the weapon cradle and comprising a pressure member which moves the trigger of the weapon between a non-firing position and a firing position, and a spring biased triggering system arranged for actuating the pressure member and releasable by a further trigger, the triggering system being adjustable between single shot and automatic firing modes of operation.
  • trigger mechanisms for automatic guns There are various known embodiments of trigger mechanisms for automatic guns. However, they are usually provided with an electric or electrohydraulic drive requiring the presence of power supplies, which may create a problem, especially in the case of field guns and particularly in cases of long-lasting fire. Furthermore, servo trigger mechanisms of a mechanical kind as described in the preamble of claim 1 are known, but the known mechanisms have a relatively complicated structure comprising a series of precision mechanical members so that such mechanisms are sensitive and difficult to maintain.
  • a device of the type defined initially is characterised in that the pressure member is mounted in a parallelogram linkage with a base frame and is liftable to a raised position by the action of a link means that is parallel with the parallelogram linkage and is biased to a raised position by spring biasing means, and in that the triggering system includes a spring biased trigger locking hook that is movable via a spring biased trigger rod mechanism, the locking hook being arranged for locking the said link means in a lowered position with its spring biasing means in a stressed condition, and an automatic locking means operable via an arm, said locking means being provided with a contact surface which, in the single shot mode, lies out of contact with the pressure member, and, in the automatic mode, lies in contact with the pressure member with the pressure member in its raised position.
  • the servo trigger mechanism is usually arranged below the weapon per se and it is, thus, essential that the overall height of the mechanism be not too large.
  • the trigger force necessary for the trigger of automatic guns is also relatively high, e.g. approximately 100 kp. This means, in turn, that the servo trigger mechanism must be able to exert relatively high force and stand the necessary load in connection with said force as well. Consequently, all elements must be structured for exerting relatively large moments.
  • the servo trigger mechanism should be of such a kind as to be driven i.e. cocked by the recoil force of the gun after an initial cocking movement that has to be carried out manually or, e.g. with the aid of an external drive member.
  • a mechanical servo trigger mechanism is achieved that is comprised of simple, sturdy elements that may easily be exchanged in case of a defect.
  • the entire device is arranged on a common bottom frame which is shaped in such a manner by simple milling methods that bearings for links and points of attachment are easily accessible.
  • the device is easily mounted in the cradle of the weapon directly below the gun and with the aid of a simple rod mechanism it may be set in a cocked condition by the recoil force of the gun.
  • the device is constructed in such a manner that very few movements need be executed in connection with automatic firing and wear may be reduced to a minimum.
  • the mechanical servo trigger mechanism is not shown in its entirety in the drawings. Instead those portions that are essential according to the invention are shown.
  • the perspective view of Fig. 1 shows how different pivots and fixing points for the separate members of the mechanism of the device are arranged on a base plate 2 serving as a frame for the mechanism of the device.
  • a base plate 2 serving as a frame for the mechanism of the device.
  • shaft mountings and fixing points for elements 3, 4, 7, 11, 14, 10 and 9 are indicated.
  • the device according to the invention will now be described with reference to the perspective illustrations in Fig. 2-5, and the perspective view in Fig. 6, the elements and their positioning being disclosed in connection with the operation of the device.
  • the trigger 17 of the weapon is indicated is broken line in Figs. 2 and 3.
  • the element of the servo trigger mechanism which acts on the gun trigger 17 is a pressure ramp 1.
  • the ramp 1 is connected with the base plate 2 via a link connection having two link members 3 arranged mutually parallel to form a parallelogram linkage.
  • the ramp 1 is liftable by the action of further link members 4 parallel with the link members 3.
  • the link members 4 are parallel on common shafts, the uppermost of these shafts 4a being indicated in Figs. 2 and 3.
  • the shaft 4a bears freely against one end of the ramp 1 as shown in Fig. 3.
  • a spring 5 (indicated in Fig. 4) coupled to the shaft 4a.
  • the spring 5 is shown in a compressed position in Fig. 4, i.e. a position in which the shaft 4a is held down as disclosed in more detail below.
  • the ramp 1 can be held in its raised position by engagement with a stop 7.
  • the stop 7 is indicated most clearly in Fig. 3 in which it is seen in a disengaged position.
  • the ramp 1 Before a first shot is fired, the ramp 1 is moved from its starting position, i.e. its raised position, to its lowered position, with the aid of a manual cocking arm of the weapon (not shown in the drawings), which may be of a conventional kind.
  • This manual cocking arm is also lockable and, thus, acts as a safety means for the weapon.
  • the cocking means may be alternatively another manual cocking mechanism or be electrically or hydraulically operated.
  • the lowered position of the ramp 1 is its cocked position.
  • the ramp 1 After firing of the first shot the ramp 1 will automatically be moved to its cocked position by the action of a cocking rod 8 (Fig. 5) which is operated by the gun recoil.
  • the cocking rod 8 is acted on by a member (not shown) on the weapon that is moved to the right in Fig. 5 due to recoil movement and, to compress the spring 5 (Fig. 4) via link members 4, itself acts on a roller 9 on these link members.
  • the counteracting force exerted by roller 9 is resisted by a second roller 10 mounted on an arm that is rigidly attached to the base plate 2.
  • the rod 8 has a chamfered portion at the end area between the two rollers 9 and 10.
  • the link members 4 In the recoil movement of the rod 8, the link members 4 are rotated rearwards and the ramp 1 on the parallelogram link members 3 is moved into its lowered position, i.e. its cocked position.
  • the ramp 1 will remain in the cocked position due to the fact that the link members 4 are kept down by a trigger hook 11, friction and springs 15 - and 20, the hook 11 being in engagement with the shaft 4a. This holding action is shown in Fig. 2.
  • the trigger hook 11 When a single shot is to be fired, the trigger hook 11 is retracted by a trigger rod 12 provided with a trigger (not shown).
  • the trigger rod 12 is located in a support 13 which in turn is mounted on a shaft 14.
  • Trigger hook 11 When its trigger is pulled, trigger rod 12 releases trigger hook 11 from the link shaft 4a.
  • Trigger hook 11 is automatically moved forward by the spring force of a spring 20 shown in Fig. 2 to catch shaft 4a when the ramp 1 returns into its cocked position.
  • the trigger hook per se is moved back into a position in which it is engaged with the shaft 4a by the spring 20.
  • the trigger rod 12 is moved forward by spring 15 when its trigger is released.
  • the device also comprises an automatic locking means in the form of the stop 7 indicated in Fig. 3.
  • the stop 7 is used in connection with automatic firing and is operated by an arm 6.
  • the arm 6 is locked in its forward position, which is shown in Fig. 3.
  • the arm 6 is unlocked, the trigger rod 12 pulled back, and spring 15 pushes against the arm 6 (see Fig. 6).
  • the spring 15, acting through the arm 6 has turned the stop 7 to a position with a surface 18 of the stop 7 in contact with a surface 18' on the ramp 1, which prevents the ramp 1 from falling down, the link members 4 being held in their lowered position by the trigger hook 11 after the firing of the first automatic shot.
  • the gun trigger 17 is held in a permanent firing position without further movement of the ramp 1 and link members 4 and, thus, with reduced wear.
