| 摘要 |
The invention relates to a supporting lattice framework which can be adjusted between a folded-in state and a folded-out state, wherein the supporting lattice framework has longitudinally extending supports, wherein the spacing between at least two of the longitudinally extending supports in the folded-in state of the supporting lattice framework is less than in the folded-out state of the supporting lattice framework, and wherein in the folded-out state of the supporting lattice framework, at least two of the longitudinally extending supports are connected to one another by struts, wherein at least one track is disposed on at least one of the longitudinally extending supports, and wherein in the region facing the track, the struts comprise means by which the struts run on or in the track when the spacing of longitudinally extending supports relative to each other changes. |
