摘要： A bathtub drainage device comprises: a plate, that can open and close an opening formed at a position corresponding to a position where a bather can sit on a floor of a bathtub in which hot water is stored, the plate on which at least buttocks of the bather can be placed; a rising part, that raises the plate closing the opening so that the opening is opened; an acquisition unit, that acquires information indicating a state of the bather; and a control unit, that controls the rising part so as to raise the plate so that the opening is opened and so as to discharge, from the opening, the hot water stored in the bathtub, when the information acquired by the acquisition unit indicates an abnormal state of the bather.

摘要： A pop up stopper comprising multiple aperture and at least one non-aperture lever rod engagement locations to allow use of the stopper as a replacement with different pre-existing actuating and drain systems when the existing stopper is broken, worn or needs to be replaced for aesthetic reasons. An existing lever rod is selectively positionable to engage with one of the lever rod engagement locations that are disposed at varying heights on the stopper. Most preferably, there are six lever rod engagement locations, four aperture locations and two non-aperture locations. A seal disposed below a cap and around a body of the stopper comprises an enlarged annular ring near its outer edge to provide increased surface area for sealing a drain opening. The body of the stopper has a maximum width measured in cross section of 1.04 inches or less.

摘要： The invention describes a quick install lift rod pop-up sink drain assembly comprising a drain body, a drain plug, a horizontal pivot rod used as a lever for raising and lowering the drain plug, a lock ring which rotatably secures the horizontal pivot rod to the drain body, and a lift rod rotatably connected to the outer free end of the horizontal pivot rod and used to raise or lower the free end of the horizontal pivot rod. A spherical portion of the horizontal pivot rod is rotatably captured inside a free end of a connector which is integral with the drain body and which contains pawls which capture the spherical portion of the rod and allow up and down movement of the rod with respect to the drain body, causing the drain plug to open and close.

摘要： A drain strainer is provided that includes a flange and a basket. The flange transitions to a central cavity. The basket defines the central cavity and includes perforations that are sized to enable liquid to drain through the basket while debris is collected in the basket. The basket has a flexibility of a sufficient value such that the basket may be stretched in a downstream direction to a predetermine value and then released to eject the debris from the basket.

摘要： A drain stopper and strainer for a kitchen sink has a cap, a cap seal, an open-close mechanism, a strainer connected to a lower end of the open-close mechanism with an easy-connect mechanism, and an annular seal engaged with the strainer that seals an annular space between the strainer and a drain fitting. The cap seal preferably seals against the strainer. The stopper/strainer can be pushed into and pulled out of the drain fitting without assembly or disassembly. The strainer can be easily disconnected for cleaning and can be easily reconnected afterwards. For a drain fitted with a garbage disposal unit, the strainer has a hub-and-spoke structure for preventing eating and cooking utensils from falling into the garbage disposal unit.

摘要： A valve assembly includes a valve head. A valve stem extends from the valve head and into a drain bore in a housing. A first guidance retainer ring is mounted around the valve stem at a first axial location on the valve stem. A second guidance retainer ring is mounted around the valve stem at a second axial location on the valve stem spaced apart from the first axial location.

摘要： A drain arrangement that comprises a housing which has a first channel section with an inlet opening, a second channel section with an outlet opening, and a valve seat situated between the inlet opening and the outlet opening. It also has a valve body which is movable from the valve seat, an actuating unit to move the valve body, and an outflow pipe into which the second channel section opens. A first central axis extends centrally through the first channel section, and an outflow pipe central axis extends centrally through the outflow pipe. The outflow pipe central axis intersects the first central axis or alternatively the outflow pipe central axis is at a distance from the first central axis. The actuating unit has an actuating lever acting on the valve body, and an actuator element for actuating the actuating lever, wherein the actuator element extends laterally alongside the outflow pipe.

摘要： 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.

摘要： A drain assembly includes a drain body and an expanding assembly. The drain body includes a first flange and a second flange that each extend away from an inner surface of the drain body towards a center of the drain body. The expanding assembly is positionable within the drain body between the first flange and the second flange. The expanding assembly includes a lattice body. The lattice body can be adjusted relative to the drain body such that the expanding assembly applies an axial force to the first flange and the second flange.

摘要： 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.
