Abstract
The balloon basket (1) according to the invention essentially comprises several pneumatic elements: an upper ring (2) and a lower ring (3), both advantageously segmented, are joined by a number of struts (4). The number of these struts (4) preferably corresponds to the number of corners of the polygonally formed rings (2, 3) and the number of their segments. Between the rings (2, 3) and the struts (4) side wall elements (5) are arranged so that they--apart from the holes (7) made in them--tightly seal the balloon basket (1) at the sides. In the lower ring (3) is fitted a floor (6). Side wall elements (5) and floor (6) are made with double walls and comprise at least in part of distance fabric such that the two corresponding walls of the side elements (5) and the floor (6) are held together by a plurality of threads and therefore retain their flat form on inflation with compressed air.
