POP-UP DRAIN STOPPER LINKAGE ASSEMBLY
FIELD OF THE INVENTION
The present invention relates to a basin accessory, and
more particularly to a pop-up drain stopper linkage assembly
adapted for the basin.
BACKGROUND OF THE INVENTION
A conventional pop-up drain stopper linkage assembly is
disclosed in US 8,136,179 B2 and contains: a lift rod fixed on a
basin on which a faucet is mounted and configured to be pulled
upward and pressed downward; a drain base screwed with a bottom
of the basin and cooperating with a screwing element, the draining
base including an outlet defined on a top thereof and a through hole
formed on a peripheral side thereof; a connector connected with the
through hole of the drain base; a coupling rod retained with a
bottom of the lift rod and moving vertically in response to the lift
rod, the coupling rod including a plurality of orifices formed
thereon; a driving rod including a first segment, a second segment,
and a spherical ball adjacent to the first segment and rotatably
connected with the connector so as to form a fulcrum, wherein the
first segment extends into the drain base from the through hole, the
driving rod also includes plural fitting portions arranged proximate
CA 02916332 2015-12-29
to the second segment, and one of the plural fitting portions
selectively fits with one of the plurality of orifices on the coupling
rod, such that the driving rod moves upward and downward in
response to the coupling rod and causes a lever movement along the
fulcrum; a drain stopper including a bottom end retaining with the
first segment of the driving rod from the outlet of the drain base,
and the drain stopper moving upward and downward in response to
the lever movement of the driving rod, wherein the drain stopper
moves downward, the outlet of the drain base is turned off, and
when the drain stopper moves upward, the outlet of the drain base is
turned off.
However, the coupling rod is removed from and is fitted
with the first segment of the driving rod repeatedly, thus fixing the
conventional pop-up drain stopper linkage assembly under the basin
troublesomely.
A distance exits between any two adjacent orifices on the
coupling rod, so the first segment of the driving rod cannot be
adjustably moved on the coupling rod.
The driving rod selectively retains with the one of the
plurality of orifices on the coupling rod by using the plural fitting
portions, and a protrusion of any two adjacent fitting portions
resists against the Plurality of orifices, thus adjusting the driving rod
difficultly.
