Abstract
An improved drain actuates system that includes a cable to actuate a head or stopper of a drain. More specifically, one end of the cable is associated with the drain without additional moving parts and another end of the cable associated with an overflow cap of an overflow system wherein rotation of the overflow cap selectively moves the cable to move the head of the drain. The internal components associated with the overflow end of the cable that allow it to actuate the drain are fully accessible through the overflow port of the plumbing system.
Claims14
A system for selectively opening and closing a drain stopper, comprising:
- an overflow assembly;
- a drain assembly, which includes a drain stopper that is selectively moved relative to a strainer body to control the flow of fluid through the drain assembly, said strainer body possessing an inwardly-disposed hub for receipt of a hollow shaft that slidingly receives a post that is associated with said drain stopper;
- a cable drive shaft having a cam rotatably associated with said overflow assembly;
- and
- a cable having a first end associated with said cam of said cable drive shaft and a second end that is positioned within said hollow shaft and directly engaged with said post.
A bathtub drain system comprising:
- a bathtub having an overflow port and a drain port;
- an overflow assembly that includes a threaded end with a flange spaced therefrom such that a portion of said overflow assembly is positioned outside the bathtub with said flange associated with an outer surface of said bathtub and wherein said threaded end is positioned within said overflow port with a portion thereof extending into said bathtub;
- a nut engaged onto said threaded portion of said overflow conduit that cooperates with said flange to firmly secure said overflow assembly to said bathtub, said nut also receiving an overflow cap that is adapted to rotate relative thereto;
- a drain assembly having a drain conduit with a flange that is associated with said outer surface of said bathtub, said drain conduit interconnected to a strainer body having an outwardly extending flange that cooperates with said flange of said drain conduit to interconnect said drain conduit to said bathtub, said strainer body also possessing an inwardly disposed hub for receipt of a hollow shaft that slidingly receives a post that is associated with a stopper that controls fluid flow through the drain conduit;
- a cable drive shaft having a cam rotatably associated with said overflow assembly;
- a cable having a first end associated with said cable retainer and a second end that is positioned within said hollow shaft and directly engaged onto said post.
