Foldable top frame for tarpaulin structure of e.g. semitrailer, has sliding elements kept apart from each other in pivoted state of running rail, where sliding elements are pivotable in region of carriage for uncovering lateral opening

摘要

The frame (10) has a set of sliding elements displaceable along a longitudinal beam (4) supported against a loading plank bed (11). A tarpaulin (15) partially closing a lateral opening (14) of the top frame. A carriage is arranged at each end of the sliding elements. The sliding elements are displaceable with respect to the beam by the carriage, and fixed at a running rail (3) assigned to the loading plank bed. The opening is uncovered by pivoting the sliding elements in the region of the carriage. The sliding elements are kept apart from each other in a pivoted state of the running rail.
