Definitions

  • the invention relates to a lock of a hunting or sporting weapon with security devices according to the preamble of patent claim 1, as well as a hunting and sporting weapon with a lock according to the invention.
  • a lock of a hunting or sporting weapon has become known, for example, with the subject matter of DE 100 46 044 A1.
  • a button-shaped actuating button is arranged on the pistol grip, which is arranged in the direction of the grip at the front of the pistol grip and behind the trigger, and points in the direction of the muzzle of the weapon. It is partially recessed in the pistol grip.
  • the safety device formed in this way has the disadvantage that when the safety device is activated before the shot is fired, the fingers of the firing hand must be separated by a motor, because three fingers of the firing hand, e.g. B. the ring finger, the middle finger and the little finger, the safety button can be pressed and held at the same time, while the index finger has to be used to gently pull the trigger in the same direction in order to fire a shot.
  • the fingers of the firing hand must be separated by a motor, because three fingers of the firing hand, e.g. B. the ring finger, the middle finger and the little finger, the safety button can be pressed and held at the same time, while the index finger has to be used to gently pull the trigger in the same direction in order to fire a shot.
  • the associated concentration task is not insignificant, because the motor movement control of the last three fingers of the firing hand has to be separated from the movement control of the index finger on the part of the brain, which is associated with a high concentration effort. A cramping of the shooting hand is very likely. This also affects concentration on firing the shot itself, which should be done with the index finger.
  • EP 3 869 142 A1 on which the invention is based, also has the same disadvantage, in which the safety button is located in front of the pistol grip and behind the trigger in the shooting direction and therefore a motor-controlled separation between the fingers that operate the safety button and the index finger that pulls the trigger.
  • Grip safety devices are known for pistols that are not of a generic type for hunting and sporting weapons, with a lever on the grip or grip of the weapon that is actuated when the grip is gripped and thus releases the previously mechanically blocked trigger sear and/or cock of the weapon.
  • the weapon can therefore only be fired if it is held firmly in the shooter's hand.
  • no shot can be fired because the grip safety is not unlocked.
  • the safety device is also referred to as a palm safety device.
  • the invention is therefore based on the object of further developing the lock of a hunting or sporting weapon, as well as a hunting and sporting weapon with such a lock, in such a way that more reliable actuation of the safety device is ensured, which does not impair ergonomic operability and hit accuracy and the trigger alone only the task namely the triggering of the shot is assigned.
  • the invention is characterized by the technical teaching of claim 1 in order to solve the technical problem.
  • a preferred feature of the invention is that the safety button is now actuated with the heel of the hand and is preferably arranged ergonomically on the rear part of the pistol grip and no longer on its front part.
  • Another advantage is that the safety device/safety button can actuate/control one or more safety devices in the weapon together. Without having to assign additional functions to the trigger.
  • the palm-operated safety button represents a significant advantage when firing a shot and when operating the safety device, which was not known in the state of the art for hunting and sporting guns.
  • the palm-operated safety button is designed as a manual tensioner, which means that with the When the safety button is actuated, the firing pin spring is fully charged and completely relaxed again if it is not actuated.
  • the safety button actuated by the ball of the hand provides a firing pin safety device.
  • the palm-operated safety button on the pistol grip of the hunting or sporting weapon is referred to below as the "palm button”.
  • the palm presser provides all four security measures individually or cumulatively, specifically in any desired combination with one another individually or collectively, viz
  • the original secured state preferably all of the safety elements—is restored immediately by releasing the palm presser.
  • a particularly preferred embodiment of a hunting or sporting weapon according to the invention relates to a bolt-action rifle that is designed as a multi-loader.
  • the lock of this bolt-action rifle is developed in a special way, the term “gun lock” meaning the trigger unit and the mechanical transmission chain for the lock controlled by the trigger unit.
  • the breech serves as the end of the gun barrel to the rear and it can contain parts of the firing mechanism.
  • the lock is the mechanism for igniting the propellant charge of a firearm.
  • the invention relates not only to bolt-action rifles that are designed as multi-loaders, but also to hunting or sporting weapons that are designed as single-loaders.
  • the focus of the present invention is therefore the lock mechanism of a hunting or sporting weapon in the above-mentioned embodiments, with a multi-loader bolt-action rifle being described for the sake of simplification, which is designed as a hunting or sporting weapon in a conventional design.
  • a multiloader bolt-action rifle is not intended to limit the scope of the lock mechanism according to the invention.
  • the lock mechanism can be used for all aforementioned types of hunting or sporting weapons and is designed in a particularly advantageous manner.
  • the focus is on the lock guaranteeing a series of security measures that are inevitably controlled by the palm presser, with the main purpose being to secure and operate the manual cocking device.
  • the hand cock remains cocked and must be actively manually uncocked so that the weapon is secured and/or uncocked.
  • the lock is automatically cocked during the bolt action and remains cocked.
  • a safety device must be activated manually in order to bring the weapon into a safe state, with the lock still being and remaining cocked.
  • the active, manual safety of the repeater is omitted, which means that the weapon remains cocked and can lead to an unintentional shot being fired.
  • the palm presser ensures that the lock is completely relaxed in its non-actuated rest position and/or ensures that the firing pin spring is completely relaxed.
  • the palm presser provides a firing pin lock in the non-actuated state, furthermore in a third embodiment provides a trigger safety device and in a fourth embodiment a locking device.
  • the palm presser is effective in the four aforementioned security measures, whereby each of the four security measures (manual cocking, firing pin safety, trigger safety, locking device) can be present individually or in any combination with one another.
  • each of the four security measures can be present individually or in any combination with one another.
  • all four security measures are made available by the palm presser according to the invention simultaneously (in the sense of together, but staggered in time) and are positively controlled.
  • the palm presser either controls only the manual cocking device (firing pin spring) or only provides the firing pin safety device or only the trigger safety device or only the locking device.
  • the palm presser combines all four security measures in a single part, namely the safety button designed as a palm presser, which leads to a particularly compact, simple and reliable lock structure.
  • Another major advantage is that the trigger only has one task, namely releasing the shot.
  • the firing pin spring Upon further depressing the palm presser toward its active, fully depressed position, e.g. B. after overcoming the pivoting path of z. B. 10 mm up to a pivoting path of 15 mm, the firing pin spring is tensioned further and there is an initial release of the firing pin, at the same time the release of the trigger begins. The clasp remains secured.
  • the weapon can then be fired after the palm presser has been fully depressed.
  • Reloading means that the cartridge is reloaded from a cartridge magazine into the cartridge chamber of the barrel by a manually operated mechanism. It is preferred if the cartridge magazine is preferably located approximately flush below the breech. If you let go of the palm presser after the shot has not been fired and does not press it again, the weapon remains fully safe and decocked, the bolt is locked via the bolt lock and there is no longer the fatal risk of an accident with a still cocked weapon that existed in the prior art, which only must be released or secured manually.
  • the operation of the palm trigger is an intuitive process, because the shooter only has to remember that he presses the palm trigger before firing the shot, but this is done automatically and intuitively with the firing position, without having to think about other motor and mental actions that were previously had to be carried out with three or two fingers of the same firing hand in the prior art.
  • the ergonomic arrangement of the palm presser at the rear of the front part of the pistol grip ensures that it can be pressed intuitively with the ball of the hand and the shooter can therefore only concentrate on the target with a relaxed index finger ready to fire, without thinking about the tension of the hand cock or carry out an arming of the weapon on various other parts of the lock.
  • the lock mechanism according to the invention in which four different safety processes are preferably actuated with a palm presser according to the invention or a safety button, works practically silently, so that no noise is to be expected before the shot is fired.
  • the palm presser according to the invention that is the safety button, which is arranged on the front inner side of the pistol grip, ensures, for example, that the firing pin spring is tensioned and secured.
  • the firing pin spring is tensioned and secured.
  • the trigger therefore only has the task of firing the shot, while all other elements, such as e.g. B. the tensioning of the firing pin spring and other mechanisms are moved into the actuation path of the palm presser.
