US 5,535,776 discloses that a device for the top mounting
of a faucet to a sink includes a generally cylindrical sleeve having a
threaded shank with an internal diameter of a size to receive the
body of a faucet and the water connections thereto. The sleeve has
an outwardly extending shoulder at one end and an upstanding wall
at the extremity of the shoulder. The shoulder is formed and adapted
to seat upon the top of a sink. Beneath the sink the shank of the
sleeve carries an elastomeric washer which is positioned adjacent
the bottom of the sink, a hard washer positioned adjacent the
elastomeric washer, and a nut which is threaded onto the shank. The
nut urges the hard washer against the seal washer and the seal
washer in turn forms a seal with the bottom of the sink. However,
many components are fixed under a limited space of the kitchen
basin.

CA 2979272 2017-09-15
The top mounting faucet assembly comprises a fixer 2, a
body 3, and a locking bolt 4. The fixer 2 includes a base 10 and a
clamper 20.
As shown in FIGS. 4-9, the base 10 includes a support
portion 10a and an insertion portion 10b integrally connecting with
the support portion 10a. The support portion 10a includes a
peripheral fence 11 and a shoulder 12 connecting with an inner wall
of the peripheral fence 11, wherein the peripheral fence 11 has a
recessed portion 111 and a first anti-rotation portion 112 which are
individually arranged on two predetermined positions of the
peripheral fence 11, and the shoulder 12 has two longitudinal holes
121 passing therethrough. The insertion portion 10b has a
cylindrical fence 13 extending downwardly from a bottom of the
shoulder 12, and the insertion portion 10b has two columns 14
arranged on an outer wall of the cylindrical fence 13, the cylindrical
fence 13 has a first passage 15 and a second passage 16 which does
not communicate with the first passage 15.
The shoulder 12 has a circular abutting area 122 defined
around the cylindrical fence 13, as illustrated in FIG. 7. When the
insertion portion 10b of the base 10 inserts through the kitchen
basin 1 from the opening la, as shown in FIG. 2, the circular
abutting area 122 contacts with the opening la of the kitchen basin

CA 2979272 2017-09-15
The clamper 20 is comprised of two screw rods 21 and two
locking protrusions 22, as illustrated in FIG. 4, wherein the two
screw rods 21 rotatably insert through the two longitudinal holes
121 of the base 10 respectively. Since the two longitudinal holes
121 are located outside the circular abutting area 122, the two screw
rods 21 rotatably insert through the two longitudinal holes 121 and
do not interfere the opening la of the kitchen basin 1.
The two locking protrusions 22 screw with the two screw
rods 21 individually so that when the two screw rods 21 rotate, the
two columns 14 of the base 10 limit upward rotation of the two
screw rods 21, and the two locking protrusions 22 engage with a
part of the kitchen basin 1 around the opening la, thus clamping the
base 10 on the kitchen basin I.
Referring to FIGS. 2, 3 and 10, the body 3 is a hollow shell
and accommodates a mixing valve (not shown) so that a cold-water
tube (not shown) and a hot-water tube (not shown) upwardly extend
to connect with the mixing valve on which a supply hose having a
counterweight is connected, wherein the supply hose is in
connection with a water supply segment of the body 10, and the
water supply segment of the body 10 has a shower or a spray head
fixed thereon. Due to the supply hose, the supply hose, the shower,
and the spray head are well-known art, further remarks are omitted.
With reference to FIG. 10, the body 3 includes a second
anti-rotation portion 3a adjacent to a bottom of an inner wall of the
body 3, wherein when the body 3 is fitted with the support portion
9
CA 2979272 2017-09-15
10a of the base 10, the second anti-rotation portion 3a connects with
the first anti-rotation portion 112 of the base 10 so that the body 3 is
stopped and does not rotate along the base 10. The body 3 includes
a threaded orifice 3b formed on an outer wall thereof adjacent to a
bottom of the body 3.
Referring to FIGS. 2 and 11, the locking bolt 4 screws with
the threaded orifice 3b of the body 3 and abuts against the recessed
portion 111 of the base 10 so that the body 3 is stopped and does
not move along the base 10, hence the body 3 does not upwardly
remove from the base 10.
As illustrated in FIG. 9, the recessed portion 111 of the
base 10 has a tilted face 111a defmed on an upper end of the
peripheral fence 11 and has an inward concave face 11 lb extending
downwardly from the tilted face 111a, such that when a distal end
of the locking bolt 4 contacts with the tilted face 1 I la, the body 3 is
forced to move downwardly.
The first anti-rotation portion 112 of the base 10 has
multiple toothed racks 112a extending along the peripheral fence 11,
the second anti-rotation portion 3a of the body 3 has multiple
internal faces 300 defined thereon and has a plurality of toothed
slots 3d formed on the second anti-rotation portion 3a so that the
multiple toothed racks 112a mesh with the plurality of toothed slots
3d respectively, hence the body 3 moves longitudinally along the
base 10 and does not rotate along the base 10.
A vertical length of the first anti-rotation portion 112 along
CA 2979272 2017-09-15
the peripheral fence 11 is less than a vertical length of the second
anti-rotation portion 3a. The first anti-rotation portion 112 has seven
toothed racks 112a extending along the peripheral fence 11, and the
second anti-rotation portion 3a has fifteen toothed slots 3d, hence
the seven toothed racks 112a mesh with seven of the fifteen toothed
slots 3d respectively, and the body 3 is in connection with the base
easily and quickly.
Preferably, the recessed portion 111 of the base 10 partially
extends around the peripheral fence 11 so that the multiple toothed
10 racks 112a of the first anti-rotation portion 112 mesh with the
plurality of toothed slots 3d of the second anti-rotation portion 3a
respectively, and the locking bolt 4 abuts against the recessed
portion 111.
In case a part of the multiple toothed racks 112a is located
outside the second anti-rotation portion 3a, they are stopped by the
multiple internal faces 300 of the body 3 so that the locking bolt 4 is
not located outside the recessed portion 111.
Preferably, the first anti-rotation portion 112 and the
second anti-rotation portion 3a are replaceable by each other.
The two columns 14 of the base 10 are integrally
connected on the cylindrical fence 13.
As illustrated in FIGS. 4-5, the support portion 10a of the
base 10 has a surrounding rib 17 proximate to a bottom of an outer
inner wall of the peripheral fence 11. With reference to FIG. 10, the
body 3 has a contacting fringe 3c formed on the bottom of the inner
11
CA 2979272 2017-09-15
wall thereof, such that when the body 3 is secured on the base 10
and screws with the locking bolt 4, the contacting fringe 3c of the
body 3 is forced to matingly contact with the surrounding rib 17 so
that the body 3 is fixed securely, and the contacting fringe 3c of the
body 3 matingly engages with the surrounding rib 17 of the base 10
to avoid water leakage from the body 3.
The support portion 10a of the base 10 has a marking zone
18 in which English letters and an arrow are formed, hence a
connection direction is distinguishable, as illustrated in FIG. 4. For
example, after the base 10 is mounted on the kitchen basin 1 by way
of the marking zone 18, the body 3 is installed on an exact position.
The damper 20 includes two positioning bushings 23
screwing with the two screw rods 21 respectively so as to stop a
removal of the two locking protrusions 22 from the two screw rods
21.
In assembly, the base 10 is mounted on the kitchen basin 1,
the damper 20 is positioned on the base 10, and the two locking
protrusions 22 are adjustably fixed at a desired angle in a specific
direction so that the shoulder 12 of the base 10 and the two locking
protrusions 22 and the two screw rods 21 of the damper 20 are
inserted through the kitchen basin 1 from the opening la.
Then, the two screw rods 21 of the damper 20 are rotated
by using a tool so that the two locking protrusions 22 are limited by
the two columns 14 to clamp around the opening la of the kitchen
basin 1, and the base 10 is secured on the kitchen basin 1 by ways
12
CA 2979272 2017-09-15
of the clamper 20.
Thereafter, the body 3 is fitted on the support portion 10a
of the base 10 so that the second anti-rotation portion 3a connects
with the first anti-rotation portion 112, and the multiple toothed
racks 112a of the first anti-rotation portion 112 mesh with the
plurality of toothed slots 3d of the second anti-rotation portion 3a
respectively, as shown in FIGS. 2 and 11, hence a rotation of the
body 3 is limited. Preferably, when the contacting fringe 3c of the
body 3 matingly engages with the suaounding rib 17 of the base 10,
the locking bolt 4 screws with the threaded orifice 3b of the body 3
and abuts against the recessed portion 111 of the base 10 until the
distal end of the locking bolt 4 contacts with the recessed portion
111 of the base 10, and the contacting fringe 3c matingly engages
with the surrounding rib 17, thus connecting the body 3 with the
base 10.
As removing the body 3 from the base 10, the locking bolt
4 is unscrewed so as to maintain or replace the body 3 easily.
Accordingly, the top mounting faucet assembly is fixed on
and is removed from the kitchen basin 1 easily and quickly.
In case the locking bolt 4 is loose, the body 3 is still
mounted on the base 10 fixedly.
