SINGLE HANDLE FAUCET AND A CONNECTING STRUCTURE
THEREOF
BACKGROUND OF THE INVENTION
Field of the Invention
= The present
invention relates to a single handle faucet and a connecting
structure thereof.
Description of the Prior Art
With reference to Fig. 1, a conventional single-handle lavatory faucet 2
(such as the 4" centerset lavatory faucet) is fixed on a basin 1 with three
holes 5
and includes two twisted inlet pipes 3 connected with a holder to feed cold
water
and hot water respectively and extending out of two of the three holes 5
located
at two sides of the basin 1 individually with two screw rods 4, thereafter the
two
screw rods 4 are screwed with two nuts 6 respectively so that the faucet 2 is
fixed on the basin 1. To prevent the nuts 6 from being stopped by the inlet
pipes
3 proximate to the screw rods 4, the nuts 6 with smaller size have to be
applied,
and a bushing 7 and an elongated press plate 8 are fitted onto each screw rod
4,
then the nuts 6 and the screw rods 4 are screwed together so that the bushing
7
and the press plate 8 engage with a bottom end of the basin 1 securely, thus
connecting the faucet 2 with the basin 1.
However, the nuts 6 and the screw rods 4 are fixed below the basin 1
and are close to a wall, therefore an operating space is limited. Moreover,
the
screw rods 4 are close to the inlet pipes 3 to operate a tool within a limited
space
CA 02751355 2013-07-30
and are interfered by the inlet pipes 3, fixing the faucet 2 difficultly.
Likewise,
the size of the nuts 6 are limited without using a larger size of nuts, and a
larger
lever arm can not be provided, so a user can not operate the nut manually but
has to use a rotating tool.
The present invention has arisen to mitigate and/or obviate the
afore-described disadvantages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description
when viewed together with the accompanying drawings, which. show, for
purpose of illustrations only, the preferred embodiment in accordance with the
present invention.
Referring to Figs. 2-5, a single handle faucet 100 according to a
preferred embodiment of the present invention is used as a single-handle
lavatory faucet (such as 4" centerset lavatory faucet) and fixed on a basin
200,
the basin 200 includes a first hole 201 located at a central position thereof
as
shown in Fig. 6 and two second holes 202 disposed on two sides thereof
respectively, wherein a diameter and a spaced distance of the first hole 201
and
the second hole 202 are limited by a standard specification individually.
The faucet 100 includes a body 10, a control valve set 20, two inlet
pipes 30, an outlet pipe 40, two screw rods 50, and two nuts 60.
The body 10 includes a housing 101 and a seat 102 as illustrated in Fig.
6, and a chamber 103 defined between the housing 101 and the seat 102 to
receive the control valve set 20, the two inlet pipes 30, and the two outlet
pipes
40, the seat 102 includes a first aperture 11 located at a central position
thereof
and two second apertures 12 fixed at two sides thereof respectively.
The control valve set 20 is a well-know structure and is fixed on the
body 10. The control valve set 20 includes a holder 21 fixed in the chamber
103
of the body 10, a valve core 22 secured in the holder 21, and a handle 23 to
CA 02751355 2013-07-30
rotate the valve core 22; the handle 23 is located above a central position of
the
body 10.
The two inlet pipes 30 are connected with the control valve set 20 to
feed cold water and hot water individually and extend out of the first
aperture 11
of the seat 102 and the first hole 201 of the basin 200 respectively along the
control valve assembly 20, as shown in Figs. 2 and 4.
The outlet pipe 40 is coupled with the control valve set 20 to flow
mixed water of the cold water and the hot water.
The two screw rods 50 include two top ends to connect with two
bottom ends of two sides of the housing 101 individually as illustrated in
Fig. 6
and two bottom ends extending out of the second apertures 12 of the seat 102
and the two second holes 202 of the basin 200 respectively as shown in Fig. 5.
The nuts 60 are screwed with the two screw rods 50 respectively and
engaged with a bottom end of the basin 200 so that the faucet 100 is locked on
the basin 200 as shown in Fig. 5. Each of the two nuts 60 includes an orifice
61
formed on a central position thereof to screw with each of the two screw rods
50
as illustrated in Fig. 7, a disk portion 62 arranged on a top end thereof, an
abutting wall 63 extending from a peripheral side of the disk portion 62 and
having a diameter more than that of the second hole 202 to retain with the
second hole 202, a groove 64 disposed in the disk portion 62, and an arcuate
guiding wall 65 fixed on a central position of the groove 64 and extending
toward the orifice 61 so that the bottom end of the screw rod 50 slides into
the
6
CA 02751355 2013-07-30
guiding wall 65 to screw with the orifice 61; the disk portion 62 includes two
wings 66 extending outward from two sides of a bottom end thereof respectively
to be manually rotated by a user easily.
Because the diameter and the spaced distance of the first hole 201 and
the second hole 202 are limited by the standard specification individually, a
centrally axial line of the inlet pipe 30 is limited within 20 to 33 mm so
that the
inlet pipe 30 is inserted through the first aperture 11 of the seat 102 and
the first
hole 201 of the basin 200. Also, a centrally axial line of any one of the
inlet
pipes 30 and the screw rods 50 is capable of being limited within 30 to 85 mm
so that the screw rod 50 is inserted through the second aperture 12 of the
seat
102 and the second hole 202 of the basin 200.
Before an installation of the faucet 100, the two inlet pipes 30 and the
two screw rods 50 are fixed on the holder 21 of the control valve set 20 and
the
housing 101 of the body 10, as illustrated in Fig. 6, and during the
installation of
the faucet 100, the two inlet pipes 30 are aligned with the first hole 201 of
the
basin 200, and the two screw rods 50 are aligned with the two second holes 202
individually, thereafter the two inlet pipes 30 are inserted through the first
hole
201 and the two screw rods 50 are inserted through the two second holes 202 to
screw with the nuts 60 respectively until the abutting wall 63 of the disk
portion
62 engages with the bottom end of the basin 200 as illustrated in Fig. 5, thus
connecting the faucet 100 with the basin 200.
Thereby, the inserting positions of the inlet pipes 30 and the screw rods
7
CA 02751355 2013-07-30
50 are spaced apart from each other, i.e., the two inlet pipes 30 are inserted
through the first hole 201 to space apart the two screw rods 50 which are
inserted through the two second holes 202 individually so that a larger space
around the screw rod 50 is formed, hence the nuts 60 are screwed with the
screw
rods 50 easily so that the faucet 100 is connected with the basin 200 quickly.
Due to the two inlet pipes 30 are spaced apart from the two screw rods
50, an enough space is obtained to rotate the nut 60 with a larger size so
that
when the screw rod 50 is screwed with the nut 60, the abutting wall 63 engages
with the bottom end of the basin 200 without using a bushing and a press
plate,
thus decreasing connecting components to save installation cost.
Because a larger size of the nut 60 is applied to connect the faucet 100
with the basin 200, a larger lever arm generates on the nut 60 so that the nut
60
is manually rotated by the user. Furthermore, the two wings 66 are formed on
the two sides of the disk portion 62 to generate the larger lever arm so that
the
wings 66 are rotated by the user's fingers to rotate the nut 60 easily,
thereby
manually fixing and removing the faucet 100 without using any tool.
While we have shown and described various embodiments in
accordance with the present invention, it is clear to those skilled in the art
that
further embodiments may be made without departing from the scope of the
present invention.
