Abstract
Disclosed herein is a mechanism for remotely opening and closing a drain of a basin by means of a flexible rod moving through a non-linear tube. The rod connects a drive member, pushed or pulled by a user, with a member linked to a plug which opens and closes the drain. Within the bend of the tube, the flexible rod and/or tube are configured to leave a void between them in order to reduce friction. The configuration of the rod may include one or more bulbous ends or a lobed cross-section.
