Definitions
- the invention relates to a device. '' Preamble of claim 1.
- German Patent 23 26 850 Such a device is described in German Patent 23 26 850.
- the present invention is based on the object of designing such a known device in such a way that it meets the requirements of practical use with regard to functional reliability when triggered, when the balloon is inflated, during actual use, and when used repeatedly has grown.
- an embodiment of the balloon and of a filling device connected to it, its arrangement in a housing and its connection to the carrier of the rescue device according to FIG. proposed the characterizing part of claim 1.
- the subclaims relate to several inventive configurations, the triggering of the rescue device or the inflation of the balloon being provided in a mechanical manner by means of a rip cord or in a pneumatic manner by means of a further compressed gas bottle which, in addition to the actual one, is connected directly to the filling device which pressurized gas cylinders are provided for filling the balloon.
- the rescue device With regard to the function of the rescue device, it is essential that the full gas pressure from the pressurized gas bottles connected to the filling device is available at the moment the balloon is opened and that the Venturi effect of the Venturi nozzles which act on the filling of the balloon sets in with a slight delay.
- the Venturi effect comes into play, i.e. In an area of reduced hydrostatic pressure but high flow velocity of the Venturi nozzles, ambient air is sucked in and additionally used for filling the compressed gas when the balloon is inflated. This means that smaller compressed gas cylinders can be used.
- OMP Air intake opening of particular importance This non-return valve closes the air intake opening when the compressed gas bottle is pierced, which in the area of the Venturi nozzles generate a brief back pressure against the filling direction. Only after the balloon counterpressure has dropped, ie after the balloon has been unfolded, are the venturi nozzles flowed through in the filling direction, ambient air being sucked in through the same air intake opening when the check valve is now open.
- the air intake opening is expediently arranged in a protected manner in the interior of a housing, so that blockage in the event of use is excluded. For safety reasons, however, the amount of pressurized gas present should be selected so that the balloon is adequately filled, although less without ambient air, than is normally provided. Such a case can occur in practice if the wearer of the rescue device actuates the rescue device late, that is, only after he and the rescue device are already inside the snow masses of an avalanche.
- the additional safety when filling the balloon is provided by the compressed gas cylinders next to the actual ones connected to the filling device.
