Abstract

A pop-up drain includes a stopper assembly, a spring and camming members. The stopper assembly, the spring and the camming members are arranged within a pipe assembly. The spring biases the interaction of the camming members so that depression of the stopper assembly results in the stopper assembly sealing the pipe assembly. A second depression of the stopper assembly results in the stopper assembly moving into a position that unseals the pipe assembly.

Description

BACKGROUND AND SUMMARY OF THE INVENTION[0001]The present invention relates to pop-up drains and, more particularly, to a pop-up drain configured to reduce clogging.[0002]Pop-up drains configured for use in basins or sinks are known. Conventional designs often operate with two rotational series of ramps fashioned with a cam profile on telescoping parts. Generally, the telescoping parts are keyed together and biased with a spring, such that a plug or cap supported by one of the telescoping parts is positioned at a first axial height. User input, which may be embodied by a pressing force, causes axial movement between the telescoping parts. The relative movement of the telescoping parts causes a slow disengagement of the keyed features. Once the keyed features have disengaged, the telescoping parts rotate relative to each other as defined by the cam profile. Following the rotation, the spring may bias the plug to a second axial height, which is defined by the cam profile.[0003]In the p...
