Definitions

  • the invention relates to a catch lever for a trigger device of a closure and a security device having firearm, in particular rapid firearm, wherein the catch lever between a lock arresting the locking position and a lock not arresting position is adjustable.
  • Rapid firearms such as submachine guns or machine guns, which are designed to deliver sustained fire, have a fairly simple trigger mechanism, of which a representative example will be described below with reference to FIGS. 8 and 9:
  • a handle in which a trigger (a) is pivotally mounted. Whose transverse pivot axis is located in the upper central region of the trigger, so that the rear, upper trigger member when pressing the trigger travels a curved path upwards.
  • This rear, upper part of the trigger acts on the front end of a catch lever (f), which in turn is mounted, pivotable about a transverse axis, in the weapon housing or in the handle.
  • the rear end of the catch lever (f) is designed as a sear (s).
  • Trigger (a) and catch lever (f) can each be cushioned or biased by its own or a common spring and are from this in its rest position
  • the sear (s) When the trigger (a) is operated, the sear (s) lowers until it releases the lug; the lock is released and the gun starts with continuous fire. If the trigger (a) is released, then the sear (s) jumps back up into its locking position, behind the latching lugs and keeps the shutter in its fire ready position (rear position). The sustained fire breaks off.
  • a pure trigger guard is often used, although precludes the unintentional actuation of the trigger, but not a yielding of the Abzugsss Hecks due to acceleration forces, for example, when the loaded, tensioned and deducted machine gun falls from a truck. Therefore, there are also fuses (w), which additionally or solely set the catch lever (f) on a securing finger (i) in its locking position. But this has the disadvantage that the lock with a secured weapon can not be withdrawn via the locked catch (f) or can jam on the catch (f), because the latter can not escape.
  • a backup roller (w) which assumes with its peripheral surface a securing finger (i) of the catch lever (f), Fig. 8. A weapon with such a fuse (w) can not be charged in the secured state.
  • the further malfunction can occur here that the weapon fires uncontrollably even with interrupted trigger action.
  • High actuating forces of the actuator for the safety device can cause the fuse to jam the securing finger (i) in the catching lever (f) in such a way that the sear (s) remains out of engagement with the latching lug on the closure.
  • This malfunction may occur when the shutter is back on its way forward immediately after the trigger operation, and a power failure causes the trigger to be released at the same time and the actuator acting on the fuse places it in its "safe" position. Position presses.
  • the catch lever (f) and the sear (s) are in their release position, and the securing finger (i) dips into the securing recess on the securing device (here: the backup roller (w)).
  • the backup roller (w) in the direction of "safe” blocks the locking finger (i) whose travel and the edge of the securing recess is so tight against the safety finger (i) pressed so that the catch (f) despite spring action not can move into its locking position.
  • the catch lever (f) is jammed over the securing finger (i) and the shutter moves freely firing back and forth until the ammunition supply is interrupted (see Fig. 9).
  • a securing element is provided, which cooperates with the securing device (for example, a backup roller) so that it always - regardless of the position of the closure or the catch lever - can be brought into their secure position.
  • the safety device can act both on the trigger and on the catch lever.
  • the invention provides an improved catch lever, namely with the subject of the present claim 1, ie with a catch lever with the features mentioned, in which the catch lever has a Sich ceremoniessele- element which is adjustable relative to the catch between a rest position and a backup position ,
  • the fuse element takes its backup position in auf Maisdem on the catch lever or on this adjacent closure, when the closure on the securing element in the forward direction exerts a force (and adjusted in the security position). In this position (the backup position), the securing element engages the securing device, if this simultaneously assumes its safe position, and sets the catch lever itself in its locked position.
  • the securing element assumes its rest position (II) and releases the catch lever, regardless of the position of the securing device.
  • the functions "locking the shutter by the catch lever” and the actual backup function “fixing the catch lever in the locking position” constructively independent, so that each component or component (here: the catch and the fuse element) optimal for its task can be designed and designed.
  • the catch lever can be robust and stable designed for the high stresses that occur in cooperation with the closure, while the fuse element does not have to endure high mechanical stress through the closure, but can be designed especially with regard to the reliable interaction with the securing device.
  • this arrangement allows actuation of the safety device in any functional state of the weapon, without components of the fuse element and the actual safety device collide with each other.
  • the catching function of the stable sear stroke on the catch lever is not impaired in case of a malfunction of the securing element. This means that the risk of a weapon which continues to shoot in an uncontrolled manner and in which the trigger is not actuated is largely excluded, at least significantly reduced, compared with the solutions known from the prior art.
  • a weapon with such a catch lever can also be loaded in the secured state, and the safety device of the weapon is effectively operable in any functional condition.
  • the securing element (101, 201) is arranged in the region of a sear (31) formed on the catching lever (21) and engaging in the locking position on the closure.
  • a sear is particularly suitable to attack stably at the closure.
  • the securing element has an actuating element which cooperates with the closure and over which it is adjustable in its securing position, and a securing part which is attached to the
  • Control element and security part can be designed and arranged as required for their respective function (claim 3).
  • the reliability of the security element is increased again by the stress of the actuating element is reduced.
  • This is achieved by the fact that the control element is located in fitting trim inside the sear profile.
  • the blocking or locking function is exercised on the closure exclusively via the sear; the securing element experiences no additional loads and in particular does not absorb any loads applied by the closing spring via the closure to the catch lever or the sear.
  • the formation of the securing element as a slide according to claim 6 allows a functionally reliable, shielded arrangement of the securing element in the catch lever.
  • the sliding direction is approximately in the running direction of the closure, whereby the stress of the securing element can be kept as low as possible when actuated by the closure.
  • the claims 7 to 10 relate to an embodiment in which the securing element is designed as a pivot lever.
  • the pivot axis extends transversely to the direction of the closure (claim 7).
  • the direction of actuation also extends for the pivoting lever in accordance with the running direction of the closure.
  • the actuating direction (the auf Maisden closure) can be deflected in a different direction of securing the second lever arm.
  • the two lever arms for example, form an angle to each other.
  • the travel and the securing travel can also be of different lengths.
  • the travel can be comparatively short and the required safety path can be made so long by the appropriate choice of leverage that sufficiently large distances are available, to leave the working area of the safety device or to get into it.
  • the securing part with respect to the required effective surfaces and its mechanical stress can be designed correspondingly large or stable.
  • Active surfaces on the securing part or the corresponding mating surface on the securing device according to claim 11 further increases the securing effect.
  • the self-locking design prevents - even with a high load of the trigger cleats against the securing effect - the effective surface of the
  • Securing part and the opposite surface of the securing device can slide off each other and so the backup function can be disturbed.
  • loads can occur, for example, at high dynamic loads (blows) on the weapon or when the trigger with high force against the securing effect should act on the catch lever; for example, when the trigger is operated by a motor against the securing device.
  • Claim 12 relates to a trigger device with a catch lever according to the invention.
  • the claim 13 relates to a handle with 'a trigger device according to the invention, which can be replaced, for example, with appropriate execution against a conventional handle without the specified security functions.
  • the handle as provided in claim 14 provided with one or more interfaces through which the trigger or the securing device can be coupled with an actuating element for their operation, so a weapon with a handle are particularly easy to use in a so-called weapon station.
