Abstract: A stopper of a bathroom sink or tub includes a shank removably connected to a base part which is connected to the sink or tub and has a drain hole. A cap is connected to the shank and has a flange that extends radially from the cap. A connection portion is formed on the underside of the flange. A seal part is connected to the connection portion and includes a support ring and a collar. The support ring has at least one hook member formed in the inner periphery thereof so as to be connected to the connection portion of the cap. A positioning portion extends from radially from the support ring. The collar is a rubber collar and has a groove in the inner periphery thereof. The positioning portion of the support ring is engaged with the groove to prevent the collar from deformation and generating noise.

Abstract: A bathtub overflow pipe structure includes an overflow pipe which includes an outlet end formed to an L-shaped end of the overflow pipe. An adaptor includes a passage defined axially therethrough which communicates with the first outlet of the overflow pipe. A first flange extends radially outward from one end of the adaptor to contact the outside wall of the bathtub. The outer periphery of the adaptor is detachably connected to the passage by threading engagement. A cover includes a cap and a column extends axially from the cap. A second outlet is defined axially in the column and communicates with the passage. The column includes two overflow holes. A ring is mounted to the outer periphery of the column which is inserted into the passage. The ring contacts against the inner periphery of the passage to combine the cover to the overflow pipe via the adaptor without any screw.

Abstract: An overflow pipe assembly includes an overflow pipe having an end portion. An adaptor is connected to the end portion of the overflow pipe and includes a first connection portion formed to the center thereof. A second connection portion which is a slot, and a third connection portion which is a bore, are respectively formed to two ends of the adaptor. A cover includes multiple protrusions which are engaged with the engaging portions of the adaptor to connect the cover to the adaptor. When installing the adaptor to an overflow pipe with two tubular parts, the adaptor does not shift by extending bolts through the second and third connection portions and connected to the two tubular parts. When installing the adaptor to an overflow pipe with a single tube, a bolt extends through the first connection portion and is connected to the tube.
