    • An offset grid drain closure assembly including a drain strainer disposed in the drain hole of a basin, a vertically movable stopper member disposed beneath the strainer and having structure complementary to the opening or openings in the strainer, and a gasket disposed immediately underneath the strainer member and having a matching opening pattern. The stopper is operably connected to an actuation device such that when actuated, the stopper is lowered downwardly from the gasket underneath the strainer or raised to approximate the gasket so as to close the strainer. The drain closure thus provides fluid tight closure of a drain with no elevated surfaces in the bottom of the fluid containing basin, either when closed or when opened.
    • 一个偏移栅格排放封闭组件,其包括设置在盆排水孔中的排水过滤器,设置在过滤器下方并具有与过滤器中的开口或开口互补的结构的可垂直移动的止挡构件,以及立即设置在过滤构件下方的垫圈 并具有匹配的开口图案。 止动器可操作地连接到致动装置,使得当致动时,止动器从过滤器下方的垫圈向下降低或升高以接近垫圈以便关闭过滤器。 因此,在关闭或打开时,排水盖可以在流体容纳盆的底部没有提升的表面提供流体密封的排水口。
