Inflatable structure for the use in an inflatable lifting device and an inflatable lifting device with two or more of such structures

摘要

An inflatable structure 12 has at least 2 inner webs 18, which is supported between upper and lower surfaces 20, 22 extend. The webs are in the angle to one another, in order, on the upper surface 20 of a different profile, in which the lower surface 22 when the structure is inflated. The structure 12 can be part of a lifting device 10, in which a number of such structures are stacked on top of one another, so that the profile on the upper surface 20 of each lower structure is in the profile of the lower surface 22 of an adjacent upper structure nests. This increases the contact surfaces region between adjacent structures, which the deflection is reduced, if the stack is subjected to a load. The webs 18 may be arranged such that at least one elevation in one of the upper and lower surfaces and at least one trough in the other of the upper and lower surfaces with respect to the raised portion is formed.
