摘要： Novel quick opening removable tray sections or deck plates for trays of fluid contact vessels having foldable closures or covers adapted to rest upon frame members which coact to form perimeters of one or more polygonal, preferably quadrangular, complementary openings in each tray. Each cover has at least a pair of closure panels hingedly connected at their adjacent inner margins. Opposed outer lateral or side margins of closure panels, which overlie complementary lateral or side frame members in spaced relationship, extend in the same general direction as their adjacent inner margins. At least one of opposed outer lateral margins is slidably confined whereby cover is removable upon elevating closure panels at their hinged inner margins and simultaneously sliding said outer lateral panel margins toward each other and out of confinement so as to permit folding of said cover. If desired, one of opposed outer lateral margins of closure panels may be hingedly connected to adjacent edge portion of tray instead of being slidably confined. Frictional fasteners detachably secure end margins of closure panels adjacent their hinged connection to underlying portions of end frame members at opposed ends of tray opening. Any of the deck plates of a tray may be removably mounted in this manner.
摘要翻译： 新颖的快速打开可移动托盘部分或用于流体接触容器托盘的甲板，其具有适于搁置在框架构件上的可折叠闭合件或盖，其共同形成在每个托盘中的一个或多个多边形，优选四边形互补开口的周边。 每个盖具有至少一对在其相邻的内边缘处铰接连接的封闭面板。 封闭面板的相对的外侧或侧边缘以相互间隔的关系覆盖互补的侧框架构件或侧框架构件，其延伸方向与其相邻的内边缘相同。 相对的外侧边缘中的至少一个被可滑动地限制，由此当在其铰接的内边缘处提升封闭面板时可以移除盖，并且同时将所述外侧边缘边缘朝向彼此滑动并且不受限制，以允许所述盖的折叠。 如果需要，闭合面板的相对的外侧边缘之一可以铰接地连接到托盘的相邻边缘部分，而不是可滑动地限制。 摩擦紧固件将封闭板的端部边缘可拆卸地固定在它们的铰接连接件的端部框架构件的下部，在托盘开口的相对端处。 托盘的任何甲板可以以这种方式可拆卸地安装。
