ABSTRACT:
A bathtub stopper for closing the drain passage of a strainer cup of a bathtub according to the present invention consists of a main body portion which has first and second components adapted to telescope longitudinally with respect to one another between an extended position and a shortened position. The components are also rotatable with respect to one another about the longitudinal axis of the main body. The first component is manually engageable to be rotatably driven about the longitudinal axis and the second component is adapted to be secured to a strainer to locate the main body in an operative position with respect to the strainer. A closure means is carried by the first component for closing the drain passage when the main body is in the shortened position, the closure means being spaced from the strainer to open the drain passage when in the extended position. A continuous cam track means extends circumferentially of one of the components and includes crest and valley portions which are longitudinally and circumferentially spaced from one another. Cam follower means on the other of the components engages the cam track means whereby, upon rotation of one component with respect to the other, the cam follower means is guided along the cam track to locate the components in the shortened position when in engagement with the crest of the cam track and in an extended position when in engagement with a valley of the cam track.
