Description

The invention relates to a device for filling a chamber in a gas pressure competition weapon with gas, in particular with preferably liquid CO ₂ or compressed air.

Known gas pressure weapons, such as those used in sports competitions, for example CO ₂ or compressed air weapons, have, apart from compression models and spring-driven models, a storage container for a certain number of shots. Refilling the storage container from larger gas bottles or compressed air bottles is always a bit difficult and is usually usually uncomfortable when you decide to go shooting and find that the storage container is no longer sufficiently filled. Because the storage container is attached to the weapon, the weapon weight continues to increase. The design option is also quite limited, since, for example in the case of compressed air weapons, a pressure reducer must be connected between the storage container and an intermediate chamber, which is emptied when the shot is fired via a valve when it is pulled off. The stockpiling, the filling of the storage container on the weapon and the subsequent control of the required small amount of gas are also very time-consuming. One example is CO ₂ : When filling CO ₂ , make sure that the storage container is cold during the filling process and that only liquid CO _{2 is} removed from a separate storage bottle into the storage container. Then the storage container must be weighed and any excess CO _{2 must be} drained off so that there is no overfilling.

In contrast, the invention is based on the object a filling device of the type mentioned Simplify and facilitate the filling process.

This task is the beginning of a filling device mentioned type solved according to the invention by a separate Charging station in which gas is stored, one with the Chamber related adapter on the weapon with which the weapon for filling the chamber can be connected to the charging station and an actuatable valve on the charging station, by actuating the chamber via the adapter can be filled with gas from the charging station.

In this filling device, the shooter can simply connect his weapon to the preferably stationary charging station from shot to shot and then has sufficient energy in the chamber (intermediate chamber) of the weapon either for only the next shot or for several shots. He has the opportunity to complete a longer training program, and always with almost the same pressure, especially when filling with compressed air, since the pressure decrease in a larger storage container of the charging station is much slower than in a normal compressed air storage container, which is conventional attached to the weapon. The drive medium, be it CO ₂ or compressed air, is removed shot by shot by the charging station during the filling process with the weapon. The charging station can be operated with compressed air, CO ₂ or another suitable gas. By uncoupling the storage container from the weapon, it can now be designed more easily and tailored more to the shooter. This leads to greater design freedom when building the weapon while reducing the weight of the weapon. Thus, the storage container on the weapon can be dispensed with, and the charging station only has to be used if necessary in order to introduce the drive medium from shot to shot in metered form into the weapon.

The shooter can e.g. a filled 3 kg gas bottle or 4 liter compressed air bottle as a storage container with for Take rifle house, this under the weapon rack on his Place the shooting range and so, e.g. by means of a hose connection, train to a charging station at his shooting range, around his weapon by coupling to the charging station, i.e. to fill his reservoir. Of the Pressure vessels of the weapon can also be used with such a filling device be used.

So that the weapon can be filled with reproducible pressure can, the adapter is preferably during the filling process centered in the charging station or to the filling opening the charging station is centered.

Because the gas (drive medium) is under pressure from the charging station flows into the chamber of the weapon, it is advantageous if the adapter during the filling process by means of a Quick release is secured to the charging station. This Quick release, e.g. a bayonet or linear lock or another clutch, is e.g. at the charging station, while the adapter on the weapon accordingly is executed.

The quick release and the valve can be separated from each other be operated electrically or mechanically. However is preferred that the valve of the charging station with the quick release and / or mechanically coupled to the centering is, so that only one handle to operate both functions is required.

In preferred embodiments of the invention, the valve is by moving a filler neck on which the Adapter is present, can be actuated. One can use the filler neck for this in its position actuating the valve Handle, in particular a pivotable lever, be provided. The handle can also be used to lock the Serve quick release by moving the Handle opened again in the opposite direction becomes.

To attach the adapter to the charging station at a defined location to be able to, is preferably at the charging station Support for the adapter provided.

If the chamber to be filled is held releasably on the adapter is, there is the advantage that chambers as required with gas supply for just one or more shots at the adapter can be attached.

Preferably, the adapter and the chamber are already on the Integrated weapon design.

To even conventional gas pressure weapons with as little as possible subsequent effort to the filling device according to the invention to be able to connect, the adapter can e.g. instead of of an otherwise provided gas storage container in a corresponding opening must be built into the weapon. Thereby the weapon weight is also reduced by the differential weight of storage container and adapter.

The invention also relates to a central filling system with a central gas storage tank and with at least two filling devices, each connected to the central gas storage tank, as described above. By branching off a larger storage bottle, several, for example three or four, charging stations can be connected, so that several shooters can refuel their weapons directly from this storage bottle. For larger clubs and events, it is possible to supply all shooters with appropriate propellants (CO ₂ and / or compressed air) via the respective charging stations via a central supply.

Further advantages of the invention result from the description and the drawing. Likewise, the above mentioned and the features listed further according to the invention individually for themselves or for several in any Combinations are used. The shown and The embodiments described are not intended to be final Understand enumeration, but rather have exemplary Character for the description of the invention.
