Definitions

  • the invention relates to an inflatable boat hull with at least one large-volume boat cell and a plurality of small-volume boat chambers arranged within the wall of the boat cell, which impart their shape and stability when the large-volume boat cell is inflated, the large-volume boat cell forming the main buoyancy body and using a corresponding opening as Storage space is usable.
  • the invention is therefore based on the object of designing it in such a way that an inflatable boat is formed in which the large-volume boat cell does not have to be inflated, or only very weakly, so that the inflating of such an inflatable boat is relatively small even when used Pumps with a low filling volume can be carried out in a very short time.
  • the invention is characterized in that when the inflatable boat body is designed in the form of an inflatable boat, the large-volume boat cell forms the closed tubular body of the inflatable boat, which can also be subjected to overpressure when or after the small-volume boat chambers are inflated.
  • the first thing to do is to inflate the small-volume boat chambers, which already give the hull its final shape.
  • Negative pressure subatmospheric pressure
  • the large-volume boat chamber 2 has practically automatically filled with air, which is now under atmospheric pressure. In order to achieve an overpressure, only a relatively small amount of air has to be pumped in.
  • the large-volume boat cell is divided by partitioning into several chambers that can be subjected to an excess pressure.
  • a small-volume boat chamber 1 is under positive pressure.
  • a large-volume boat cell 2 is under normal pressure.
  • the boat chamber 1 When the boat chamber 1 is filled up, it has approx. 20 to 30% of the air content in the boat cell 2.
  • a valve in the boat cell 2 When the boat chamber 1 is filled, a valve in the boat cell 2 is open. It is thereby achieved that the object to be inflated (inflatable boat) already approximately reaches a certain shape, ie, by inflating the boat chamber 1, the boat cell 2 is already approximately filled by the resulting negative pressure. If the boat chamber 1 is filled, the valve of the chamber 2 is closed. It is also possible to use a check valve. It may then only be necessary to generate the required pressure in the boat cell 2 only by pumping.
