Benefits of technology
[0006]In another embodiment, a drain closure device is for use in first and second tub drains. The drains each define a substantially cylindrical passage, have outer radial edges with diameters, and a central threaded bore. The size of the respective threaded bores differs from each other. The drain closure device has a stopper, hollow shaft and reversible stem. The stopper has a top portion, a bottom portion and a diameter D1. The hollow shaft extends downwardly from the stopper. The hollow shaft and stopper are substantially coaxial. The reversible stem has an axial length and opposite first and second ends. The respective ends of the stem have threaded outer surfaces of different sizes. The hollow shaft is slidably engaged with and disengagable from the stem. The device is installable in a first drain by mating of the first threaded end of the stem with the threaded bore of the drain. The mating fixes the stem in the first drain such that the stem and stopper can be slidingly reciprocated from a raised opened position to a lowered closed position. The stopper seals the tub from the first drain passage in the lowered closed position. The device is installable in a second drain via disengagement of the stem from the hollow shaft, axial reversal of the stem and re-engagement to the hollow shaft, and mating of the second threaded end with the second drain threaded bore. The diameter D1 of the stopper is at least equal to the diameter of the outer radial edge of either of the first and second drains.

Problems solved by technology
The varying finishes on drains and stoppers and the sizes of threaded bores in drains create obvious challenges for repair, replacement and / or installation.

Embodiment Construction
[0017]With reference to the drawing wherein like numerals represent like parts throughout the Figures, a universal drain stopping device with an enlarged stopper is disclosed. Embodiments allow installers to use the same device in tub drains with central threaded bores of different sizes. Additionally, embodiments allow the aesthetics of a drain to be altered without replacing the drain itself or any other plumbing pieces.
[0018]As depicted in FIG. 1, this embodiment of the drain stopping device 10 has a stopper 12, hollow shaft 14 and reversible stem 16 engaged in a substantially coaxial arrangement. The reversible stem 16 has opposite first and second ends, 18 and 20, separated by a body 22. An opening 24 that defines a track extends axially along the body 22. As can be seen, the first and second ends, 18 and 20, have threaded outer surfaces, 48 and 50, of different sizes. In one preferred embodiment, the first end has an approximately 5 / 16 inch diameter and the diameter of the sec...

A universal drain stopping device with enlarged stopper is installable in drains having different sized central threaded bores. A stopping assembly with a stopper and hollow shaft is removably engageable with a reversible stem. The stopping assembly and stem are axially reciprocable relative to each other when engaged. The reversible stem has opposite threaded ends having different sizes. The device is installable into a drain by threaded mating of one end of the stem with the central threaded bore of the drain. The stem can be axially reversed for installation into another drain with a different sized threaded bore. The stopper has a diameter that is greater than the outer diameter of the drain in which the device is installed.
Description
BACKGROUND OF THE DISCLOSURE[0001]The present disclosure relates to drain stoppers, and more particularly, to drain stopping devices that are installable in tub drains with threaded central bores, such as a bathtub or the like.[0002]Most consumer tubs, such as bathtubs, can be ordered in a wide variety of sizes, styles, and colors. Regardless of this wide variety of available options, nearly all bathtubs can be fit with a drain having a central threaded bore that is mateable with the threaded stem of a variety of drain stopping device. Appropriate drain stopping devices generally comprise a stopper carried on a threadably mateable stem. However, drains with different sized threaded bores exist in the marketplace, requiring stopping devices with like sized thread on the appropriate stem end. For instance, drains are commonly sold with ⅜ inch and 5 / 16 inch diameter threaded bores.[0003]Additionally, most drains are fit with outer radial flanges that extend beyond the diameter of an in...
