Abstract
An operating device for handling a cover for a hatch of the type composed of at least three successive cover panels hingedly connected to one another comprising first operating means for partially folding the first and second cover panels, and other operating means for folding the third cover panel, constituted by at least one articulated lever located outside the rolling track defined by the coaming rails or bars on which the rollers of the second and third cover panels move.
Claims20
Operating apparatus for a folding cover system for a shipboard hatch coaming or the like having two parallel side walls and two end walls, the system including at least three rectangular cover panels, each panel being hingedly connected at one edge to an adjacent edge of the next panel, and a first one of the panels being hingedly connected at the edge opposite said one edge to a fixed support adjacent to one end wall of the coaming, the operating apparatus being actuable for moving the panels between a covering position in which the cover panels rest substantially in a common plane on the rim of the coaming and a stowage position in which the panels are folded together about said hinged connections to a substantially upright position adjacent to said one end wall of the coaming and including operating means for pivoting the first panel about the fixed support to an approximately upright position, thereby at least partially folding the second panel against the first panel, and means for folding the third cover panel about its hinged connection with the second panel, wherein the means for folding the third panel comprises:
- at least one lever mounted for pivoting about an axis adjacent and parallel to said one end wall of the coaming, the lever having a bearing means with a surface spaced from the pivot axis for slidably contacting the under surface of a portion of the third cover panel at a location spaced from the hinged connection between the third and second panels when said first and second panels are in said at least partly folded upright position, and
- actuating means, hingedly connected to the lever at an actuating point spaced from the pivot axis, for pivoting the lever into contact with the third panel and then folding said panel upward toward the folded second panel about the hinged connection between said panels, with the surface of said bearing means being free to slide against the under surface of said portion of the third panel as said third panel is being folded upward against the second panel.
