Abstract

A bathtub overflow pipe includes an overflow pipe, an adapter and a over. The overflow pipe includes an extending section with an outlet. The adapter is connected to the end face of the extending section of the overflow pipe by bolts. The adapter includes a sleeve and a tab extending radially from one end of the sleeve. The sleeve includes a passage and is inserted into the outlet of the overflow pipe. The tab has a recess formed to its lower edge and communicating with the outlet for drainage. The cover includes a pillar and a rim which has a recessed area. The pillar extends axially from one of two sides of the cover and has a rib. The pillar extends through the passage of the adapter, the rib is slidably engaged with the recessed rail. The cover, the adapter and the overflow pipe can be precisely and easily assembled.

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 adaptor for connecting a cover to an overflow pipe includes an H-shaped body which is installed in an end portion of the overflow pipe. The lengthwise length of the adaptor is not longer than the outer diameter of the end portion of the overflow pipe. The adaptor includes a first connection portion formed to the center of the adaptor, and two second connection portions respectively formed to two ends of the adaptor. Two lateral sides are formed to two sides of the adaptor. The cover includes a notch communicating with the end portion of the overflow pipe. Multiple protrusions extend from the inner bottom of the cover. The protrusions are engaged with the two lateral sides of the adaptor to connect the cover to the adaptor. Bolt(s) extend through first or second connection portions of the adaptor and are connected to the end section of the overflow pipe.

Abstract

A drainage assembly for a bathtub includes a stopper unit having a base including a drain passage and a lock hole defined through a bottom thereof. A drain pipe includes a tub shoe at one end thereof and the tub shoe communicates with the drain passage. An extension extends from the inner bottom of the tub shoe. A guide member includes a rod which includes a first connection portion formed on the first end of the rod, and a hook formed on the second end of the rod. The first connection portion is detachably connected to the extension to extend the rod through the lock hole so as to align the tub shoe with the base, and to connect the outer threads of the base with the inner threads of the tub shoe easily.

Abstract

An overflow pipe assembly of a bathtub includes an overflow pipe having a horizontal fitting end which has outer threads on outside thereof. A flange extends from the outside of the fitting end. A buffering ring is mounted to the fitting end and clamped between the flange and the wall of the bathtub. Two slots are defined axially in the passage of the fitting end. A locking ring is threadedly connected to the outer threads of the overflow pipe. A cap is mounted to the fitting end and has a peripheral wall which includes multiple drain holes. The cap has a tubular portion inserted into the passage. The tubular portion has a central hole which communicates with apertures defined through the wall of the tubular portion. The tubular portion has two protrusion which are engaged with the slots of the fitting end.
