Abstract:
1. A drain closure device for mounting to a strainer defining a fluid passage with a flange extending outwardly about an upper end thereof, said drain closure device comprising: a stopper having a sealing member for sealing against said flange and a stem depending from said stopper, said stem and said stopper being rotatable about a stopper axis; a guide member defining a sleeve for extending about and receiving at least a portion of said stem for relative rotational and longitudinal sliding movement therebetween respectively about and along said stopper axis; said guide member further defining a continuous upper ramped cam surface; a cam follower extending from said stem for following said ramped cam surface in response to rotation of said stopper about said stopper axis, said ramped cam surface being profiled to cause axial movement of said sealing member between an open configuration away from said guide member and a closed configuration toward said guide member, said cam follower held in contact with said ramped cam surface solely by gravity forcing said cam follower downward and against said ramped cam surface, said ramped cam surface remains stationary as said cam follower moves along said ramped cam surface during movement of said sealing member between the open configuration and the closed configuration; said ramped cam surface including a detent for maintaining said stopper in said open configuration absent rotational input to said stopper; and said guide member further having a securing component configured to secure said guide member to said strainer.
