Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates a decorative finial structure
for curtain rods, comprising a decoration unit and an assembly unit
wherein the decoration unit has a decorative layer of various
designs and colors wrapped at the outer surface of a main body
thereon, and the assembly unit is made up of a sealing cap and a
coupling sleeve to be mounted at both ends of the main body
thereby, a fixing rod respectively engaged with the sealing cap and
the coupling sleeve thereof, and a retaining member securely
screwed up to the fixing rod extending outwards at the other side
of the main body thereof to provide a curtain decorative finial
thereby; thus, the decoration unit is separately made from the
assembly unit so that, for variation of different designs, the
curtain decorative finial thereof can simply change the decoration
unit without the assembly unit being replaced as a whole set
therewith, and the decorative layer fastened at the outer surface
of the main body thereof can also facilitate versatile and
limitless stylistic changes of the curtain decorative finial
thereof.
[0002] Please refer to FIG. 1. A conventional curtain decorative
finial 10 is integrally made up of a decoration section 11 and an
assembly section 12 wherein the assembly section 12 is shaped into
a tubular sleeve to be mounted to both ends of a curtain rod 20
respectively before a screw 13 is fixedly screwed up to a screw
hole 121 of the assembly section 12 to secure the decorative finial
10 onto the curtain rod 20 thereby.
[0003] There are some drawbacks to such conventional curtain
decorative finial 10. First, the decoration section 11 of the
decorative finial 10 is integrally made with the assembly section
12 thereof. As a result, to change the design of the decoration
section 11, new mould of the decorative finial 10 must be cast as a
whole set for the purpose, which is not only uneconomical and
inefficient in the production and processing thereof, but also make
it rather uncompetitive on the market. Second, for variation of the
pattern of the decoration section 11, the decorative finial 10 as a
whole set must be replaced with a new one, which makes it rather
limited in stylistic changes thereof. Third, once the assembly
section 12 of the decorative finial 10 is mounted to the curtain
rod 20, a stepwise section of a larger diameter is unevenly exposed
at the coupling joint thereof, which tends to mar the smooth
surface of the curtain rod 20 and awkwardly destroy the look of the
decorative finial 10 as a whole.
SUMMARY OF THE PRESENT INVENTION
[0004] It is, therefore, the primary purpose of the present
invention to provide a decorative finial structure for curtain
rods, including a decorative finial made up of a decoration unit
and an assembly wherein the decoration unit is separately made from
the assembly unit so that, for variation of different designs, the
curtain decorative finial thereof can simply change the decoration
unit individually processed and replaced without the assembly unit
being processed or replaced as a whole set, economically saving the
cost of mould-casting and replacement thereof as well as
facilitating a synchronic processing thereof to achieve
standardized mass production for more competitive power on the
market.
[0005] It is, therefore, the second purpose of the present
invention to provide a decorative finial structure for curtain rods
wherein the assembly unit is made up of a sealing cap and a
coupling sleeve having a stop ring and a protrusive ring
respectively to precisely abut against both ends of a main body of
the decoration unit, and neatly join to the adjacent edge of a
decorative layer fastened at the outer surface of the main body and
to the outer diameter of a curtain rod so as to form an even
spherical surface therewith and keep a smooth rounded appearance
with the curtain rod thereby. Besides, the stop ring and the
protrusive ring thereof can also isolate and highlight the
decorative layer in color and texture to provide a delicate final
touch to the look of the curtain decorative finial as a whole.
[0006] It is, therefore, the third purpose of the present invention
to provide a decorative finial structure for curtain rods wherein
the decorative layer of various designs fastened at the outer
surface of the main body of the decoration unit can also facilitate
versatile and limitless stylistic changes of the curtain decorative
finial thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Please refer to FIG. 2 showing an exploded perspective view
of the present invention. The present invention is related to a
decorative finial structure for use of curtain rods, comprising a
decorative unit 30 and an assembly unit 40 wherein the decorative
unit 30 is made up of a hollow and tubular main body 31 with a stop
flange 311 disposed at both ends thereof respectively, and a
decorative layer 312 of leather and colored (like brown, or black)
material that is wrapped and preferably fastened at the outer
surface of the tubular main body 31 thereof The assembly unit 40
includes a sealing cap 41, a coupling sleeve 42, a fixing rod 43,
and a retaining member 44 wherein the sealing cap 41 and the
coupling sleeve 42 thereof are respectively matched to the inner
diameter of the main body 31 for mutual engagement therewith. At
one side of the sealing cap 41 and at the middle section of the
coupling sleeve 42 are respectively disposed a stop ring 411 and a
protrusive ring 421 that are correspondingly matched to the outer
diameter of the decorative layer 312 and a curtain rod 20
respectively. At the center of the sealing cap 41 and the coupling
sleeve 42 are respectively equipped with a screw hole 412 and a
coupling hole 422 to mate with the fixing rod 43 thereby. The
retaining member 44 is provided with a central thru-hole 441, a
polygonal limiting groove 442 defining the other side of the
central thru-hole 441 thereof, and a screw nut 443 adapted at the
limiting groove 442 therein. The outer periphery of the retaining
member 44 is annularly surrounded by a plurality of protrusive
resilient ribs 445 that, each having an arcutate guide facet 444
disposed at one end thereof, figures an outer diameter larger than
the inner diameter of the curtain rod 20 thereof.
[0013] Please refer to FIGS. 3 to 4 inclusive. In assembly, the
fixing rod 43 of the assembly unit 40 is correspondingly screwed up
to the screw hole 412 of the sealing cap 41. Then, the fixing rod
43 extending outside the sealing cap 41 is mounted to the main body
31 from one side till the stop ring 411 of the sealing cap 41 abuts
precisely against the stop flange 311 defining one end of the main
body 31, permitting the fixing rod 43 to protrude outwards at the
other end of the main body 31 thereof. The coupling hole 422 of the
coupling sleeve 42 and the thru-hole 441 of the retaining member 44
are sequentially guided through the fixing rod 43 respectively to
mount at the other side of the main body 31 thereof till the
protrusive ring 421 of the coupling sleeve 42 abuts accurately
against the stop flange 311 defining the other end of the main body
31 thereof The retaining member 44 is then rotated to engage the
screw nut 443 adapted at the limiting groove 442 therein with the
fixing rod 43 so as to secure tight and locate the retaining member
44, the coupling sleeve 42, and the sealing cap 41 at both ends of
the main body 31 to provide a curtain decorative finial thereby.
The arcuate guide facets 444 of the retaining member 44 are led
along one end of the curtain rod 20 and forced there-into till the
protrusive ring 421 of the coupling sleeve 42 abuts against the one
end of the curtain rod 20 and the resilient ribs 445 thereof
tightly inserted and retained at the inner barrel of the curtain
rod 20 therein, permitting the decorative finial thereof to be
precisely and stably held in place at both ends of the curtain rod
20 thereby. Therefore, via the decoration unit 30 separately made
from the assembly unit 40, the curtain decorative finial thereof
can achieve variation in style simply by changing the decoration
unit 30 individually processed and replaced without the assembly
unit 40 being processed or replaced as a whole set therewith,
economically saving the cost of mould-casting and replacement
thereof Besides, the decoration unit 30 and the assembly unit 40
can be synchronically processed to facilitate a standardized mass
production thereof for more competitive power on the market.
Furthermore, the stop ring 411 of the sealing cap 41 and the
protrusive ring 421 of the coupling sleeve 42 thereof are precisely
abutted against both ends of the main body 31 and evenly joined to
the adjacent edge of the decorative layer 312 and the outer
diameter of the curtain rod 20 to form a neat and smooth spherical
surface therewith. And, in addition to keeping an even and rounded
appearance with the curtain rod 20 thereof, the stop ring 411 and
the protrusive ring 421 thereof can also isolate and highlight the
decorative layer 312 in color and texture to provide a delicate
final touch to the look of the curtain decorative finial thereof as
a whole.
[0014] Please refer to FIG. 5 showing another embodiment of the
present invention in assembly. The decorative layer 312 of the
decoration unit 30 can also be made to spirally wound around the
outer surface of the main body 31 to form a unique style of the
curtain decorative finial thereof.
