Decorative finial structure for curtain rods

Abstract

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.
