专利汇可以提供Inflatable canopy专利检索，专利查询，专利分析的服务。并且An inflatable canopy which is primarily intended to be utilized in at least partially enclosing the space between an aircraft loading bridge and an aircarft can be constructed utilizing an inflatable member divided up into interconnected internal sections so that when the member is inflated, the inflatable member will flare outwardly from an essentially flat folded position to an inflated position corresponding to the shape of an aircraft hull. A frame means for supporting the sections of the inflatable member in both the folded and inflated positions is provided along with a counterweight folding means for moving the canopy from the inflated position to the folded position. The inflatable member is preferably mounted on a frame body pivotally connected to an aircraft loading bridge. This frame body may be spaced from the bridge; the space between it and the bridge may be enclosed by a bellows.，下面是Inflatable canopy专利的具体信息内容。

10. An inflatable canopy as claimed in claim 9 including: counterweight means for automatically pivoting said supports and moving said sections from said inflated position to said folded position when said inflatable member is not inflated.
11. An inflatable canopy as claimed in claim 9 wherein: said sides of said sections are successively shorter in accordance with their placement relative to said first of said sections, said sides of said sections other than said first of said sections have ends which are open into the interiors of the sides of the next adjacent of said sections, said legs of said supports are successively shorter in accordance with their locations relative to said first of said supports, said sides of said sections and said legs of said supports being of such lengths that said sections and said supports lie together in a compact unit when said inflatable member is in said folded configuration and extend in the same general configuration when said inflatable member is in said inflated configuration.
12. An inflatable canopy as claimed in claim 11 wherein: said first of said sections corresponds to said first of said supports and wherein, each of the other of said sections corresponds to each of said other supports, each of said supports serves to support one of said sections at the top of said member in all positions of said member in order to control the sagging of said top of said member.
