Gasket seals for drain closures

An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a head of the drain closure assembly that is fastened to a top end of a stem, wherein the bottom end of the stem is insertable in a drain shoe. The assembly further includes a gasket fastened around an outer cylinder of the stem below the head. Accordingly, the gasket comprises a series of concentric annular platforms such that a force applied to a top surface of the gasket causes an upper concentric annular platform having a smaller outer diameter to be compressed before the lower concentric annular platform having a larger outer diameter is compressed, thereby creating a seal between the head of the drain closure assembly and the drain shoe.

Kits for reducing inventory of sink drain assemblies
11702829 · 2023-07-18 · ·

A method is provided for a plumbing parts supplier to reduce inventory of sink drain assemblies. Drain assemblies for overflow-type sinks have an overflow port, while drain assemblies for vessel sinks do not. Some drain assemblies have open and closed positions, while a grid drain or an umbrella drain does not. A drain assembly may be available in different finishes. Rather than having an inventory of drain assemblies for all possible applications, kits are provided that allow an end-user to assemble one of two or more drain assemblies. One kit includes a drain assembly for an overflow-type sink and a sleeve that fits in the drain assembly and covers an overflow port. Other kits include a drain assembly with a push-type open-close mechanism and means for keeping the drain assembly in the open position. Another kit includes a push-button drain assembly with an overflow port, means for converting it an umbrella drain and a sleeve for covering the overflow port.

Magnetically actuated pop-up drain assembly
11549246 · 2023-01-10 ·

A magnetically actuated pop-up drain assembly includes a tailpiece having an upper end, a lower end and a hollow interior. Axially received within the tailpiece interior is a plug including a dome-shaped cap with an elongated stem depending therefrom. Proximal a lower end of the stem are an upper magnet having a predetermined polarity and a lower spaced magnet having an opposite polarity. Slidably mounted on the outer surface of the tailpiece is an outer magnet having an upper pole identical to a lower pole of the upper magnet, and a lower pole identical to an upper pole of the lower magnet. Accordingly, upward movement of the outer magnet will repel the upper magnet and lift the stem. Conversely, downward movement will repel the lower magnet, which lowers the stem.

Drain flange cover and strainer
11517155 · 2022-12-06 · ·

A drain flange cover is provided for covering and hiding a drain flange in a sink or bathtub, which includes a drain cap and which may or may not include a longitudinal shaft and/or a strainer. The longitudinal shaft can be a perforated tube that serves as a strainer. Strainers can be cylindrical, regular-funnel shaped and inverted-funnel shaped. A drain stopper includes an open-close mechanism, a strainer and a drain flange cover. A drain stopper with a push-push mechanism can rest on a cross-member in a drain pipe, allowing easy removal to clean the strainer.
