Decorative finial structure for curtain rods
A decorative finial structure for curtain rods comprises 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 with a stop ring and a coupling sleeve with a protrusive ring to be mounted at both ends of the main body of the decoration unit thereby. A fixing rod is adapted at the interior of the main body of the decoration unit and respectively engaged with the sealing cap and the coupling sleeve thereof before a retaining member is securely screwed to the fixing rod extending outwards at the other side of the main body thereof to provide a curtain decorative finial made up of the decoration unit and the assembly unit that are separately made each from the other. Therefore, the curtain decorative finial thereof can achieve variation in style simply by changing the decoration unit individually processed and replaced without the assembly unit being processed or replaced as a whole set therewith, economically saving the cost of mould-casting and replacement thereof. Furthermore, the decorative layer of the main body thereof can also facilitate versatile and limitless stylistic changes of the curtain decorative finial thereof.
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.

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 INVENTIONIt 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.
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.
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.
BRIEF DESCRIPTION OF THE DRAWINGS
Please refer to
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.
