Abstract

PURPOSE:To simplify the construction of a folding type hatch shutter mechanism by providing a triangular plate on a turning shaft of a neighboring hatch panel at a vertex and fixing a link connected to an operation cylinder and an operation link connected to another panel on turning shaft at other two vertexes of the traiangular plate. CONSTITUTION:A triangular plate 1 is fixed on a turning shaft 4 of a neighboring hatch panel of a folding hatch cover at its one vertex. At other two vertexes of the triangular plate 1, turning parts 6 and 7 are respectively provided; to one turning part 7, a link 3R connected to an operation cylinder 3 is connected, and to other turning part 6, a link 2 connected to another hatch panel is connected. By arranging operation links respectively via the triangular plate 1, hatch panels can be opened and closed by the operation cylinder individually. This construction permits to simplify the opening and closing mechanism of a folding type hatch cover as a whole.
