Description

The invention relates to a device for stunning livestock. Out of DE 20 2022 102 648 U1 A cattle stunning device is known comprising a housing for the movable storage of a firing pin, which can be ejected from an opening in the housing, a drive unit for ejecting the firing pin, and a movable firing pin which can be cocked to trigger the drive unit and be brought into a firing preparation position. In the cocked state, the firing pin protrudes from the housing at least with one outer end. At least one elastic buffer element is arranged or formed at the outer end of the firing pin. Based on the prior art, the invention aims to further improve the ease of use and the associated safety of a livestock stunning device. The problem is solved according to the invention with the features of claim 1. Further practical embodiments and advantages of the invention are described in connection with the dependent claims. A cattle stunning device according to the invention has the following elements: a housing for the movable storage of a firing bolt that can be ejected from an opening in the housing, an intermediate piece with a drive unit for ejecting the firing bolt, a movable firing pin which can be brought into a firing preparation position by cocking before the triggering of the drive unit and a release lever to trigger the drive unit, including at least the following additional element: a) a cartridge ejection element fixed to the intermediate piece but axially displaceable, which is suitable for at least partially ejecting a cartridge which is inserted into a cartridge chamber formed in the intermediate piece. Optionally, a safety element that functionally interacts with the release lever may also be provided, which is movable between at least one locking position for locking the release lever and at least one release position for unlocking the release lever and/or A safety element such as the one mentioned above ensures in a locked position that the trigger lever is locked and thus permanently prevents accidental triggering, especially if the animal stunning device is placed roughly on the ground or accidentally falls so awkwardly that contact with the ground or other objects causes force to act on the trigger lever. A cartridge ejection element fixed to the intermediate piece but axially displaceable according to feature a), which is suitable for at least partially moving out a cartridge that is inserted into a cartridge chamber formed in the intermediate piece, has the advantage that the user does not need any further aids to safely and conveniently release a cartridge - especially a used one - from the cartridge chamber in order to then remove and dispose of it. A cartridge ejection element according to the invention is preferably designed as an ejector. More preferably, the cartridge ejection element is positively locked to the intermediate piece so that it is arranged in a captive manner. Thus, both the safety element and the cartridge ejection element fixed to the intermediate piece, as described in feature a), further improve the ease of use and the associated safety of a livestock stunning device. Both elements are relatively movable and counteract the risk of operator error or injury. The safety element significantly reduces the risk of misfiring. The cartridge ejection element eliminates the need for separate, pointed tools, which were frequently used in the past for removing fired cartridges. The safety element can be designed as a locking ring element that at least partially surrounds the housing. In this case, the safety element is a partially annular or fully annular element. Such a safety element can be mounted relatively easily and designed to be relatively movable in the circumferential direction. Furthermore, such a safety element can be arranged to surround the release lever. In this case, the release lever itself can serve as a stop for the safety element. Alternatively, two elements directly surrounding the release lever, in particular projections formed on the housing, can each serve as a stop for the safety element. Preferably, the partially annular or ring-shaped safety element is rotatably mounted on the animal stunning device so that it can be easily adjusted between the locked and released positions by rotating it. The locking ring is further preferably... At least one deviation in shape (e.g., one or more radially inwardly projecting resistance element(s)) is designed such that a certain minimum torque is required to rotate it. Preferably, it is designed to remain free of play in any angular position when no torque is applied to it. The locking ring is preferably made of plastic or rubber. In a cattle stunning device with a safety element, the safety element may have at least one locking surface that can be moved into a locking position such that the release lever cannot be actuated and/or the firing pin cannot be cocked into a firing preparation position. Particularly high safety is ac
