Prefabricated Selter with Retractable Cover

摘要

The improved prefabricated selter 10 includes a truss frame that provides the elevated gable lid 12 in a raised extension shape. The cover 12 is supported by a center truss pair 90 and an outer peripheral truss pair 42 and at least three legs 18 of the link members pivotally connected in the shape of scissors. The linking members 66 of the pair of peripheral trusses 42 are pivoted together in a modified scissors shape to extend from a first assembly position extending horizontally between neighboring legs to a second extension position extending over this leg. The lid 12 can be raised in a gable shape. In a preferred embodiment, the extension cable 140 is secured between the legs 18 and the center support connected to this center truss pair 42 to provide additional strength and stability to the framework of the selter 10 in a raised extension shape. to provide.
