Abstract
The ornamental accessory comprises a planar structure having a uniquely feathered periphery. The particular accessory illustrated is in the form of a star which frictionally engages about a bulb of a string of lights. The injection molding method for producing the accessory comprises the steps of: producing a two piece die for the desired base configuration for the accessory; clamping the die closed through application of clamping pressure against the pieces of the die; and injecting a suitable substance into the die at a pressure greater than the clamping pressure to allow the injected substance to bleed outwardly between the pieces of the die.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to an ornamental accessory and method of making same. More particularly the accessory is injection molded in an unorthodox manner to provide a feathered edge thereto, with the method providing the feathered edge configuration.




2. Prior Art




Heretofore, ornamental accessories have been proposed for use in combination with lights such as those used to decorate a tree at Christmas, for example. Such accessories are usually in the form of a reflective backing for the bulbs of the lights, or have taken the configuration of an item into which the bulb is inserted to light same.




However, to date, there has not been proposed an ornamental accessory as described hereinafter or the method of making same.




SUMMARY OF THE INVENTION




According to the invention there is provided an ornamental accessory incorporating a center throughbore defined within the accessory and a plurality of radial arms protruding outwardly from and around said throughbore.




Further according to the invention there is provided a method for creating by injection molding an accessory having a feathered configuration along an outer periphery thereof comprising the steps of producing a two piece die for the desired base configuration of the accessory; clamping the die closed through application of pressure against the pieces of the die; and, injecting a suitable substance into the die at a pressure greater than the clamping pressure to allow the injected substance to bleed outwardly between the pieces of the die.




Still further according to the invention there is provided an ornamental accessory made by the above method.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings in greater detail, there is illustrated in

FIG. 1

an ornamental accessory


10


having a simple base configuration of a planar star


10


, which is created using known injection molding techniques.




As shown, the star


10


incorporates a center throughbore


12


defined within a collar


14


having nubs


16


thereon which extend radially into the throughbore


12


. In the particular embodiment disclosed, the throughbore


12


is sized to be frictionally engaged over the circumference of a miniature light bulb


13


of a string of decorative lights (not shown) although this should not be construed as limiting.




Extending radially outwardly of the collar


14


is a plurality of arms


18


. Each arm


18


includes a center rib


20


from each side


21


of which a thin flange


22


extends, each flange widening across its extent as it becomes more proximal to the collar


14


.




As is known in the art of injection molding, each line and surface is ear, crisp, and precise.





FIG. 2

is a side view of the accessory


10


showing same to be a substantially planar element, with the collar


14


being the widest portion of the accessory


10


. In a preferred embodiment of the invention, as illustrated in phantom, more than one accessory


10


can be engaged to a single miniature bulb


13


by stacking if desired. From this Figure, it will also be confirmed that the flanges


22


are far thinner than the center rib


20


of each arm


18


.




Turning now to

FIGS. 3 and 4

, there is illustrated therein an ornamental accessory


10


also having a base shape of a star


10


, identical to that of FIG.


1


.




However, using the method to be defined hereinafter, the crisp, clean lines of each flange


22


have been eradicated and replaced by a feathered edge


30


.




Although the star


10


of

FIG. 1

is very aesthetically pleasing when lit up by the bulb


13


over which it is engaged, the star


10


of

FIGS. 3 and 4

is far more ornate and breathtaking when lit by the bulb


13


over which it is engaged, creating an exceedingly spectacular vision, most particularly when a plurality of such stars


10


are engaged onto a single bulb


13


and set askew from one another.




Light from the bulb


13


appears to shoot down the rib


20


of each arm


18


, diffusing laterally outwardly therefrom across the flanges


22


, creating an enlarged area of light about the bulb


13


.




It is proposed in a preferred embodiment for the accessory


10


to create same from a clear transparent plastic, though this should not be construed as limiting.




Also, although a simplistic form of a star


10


is used as exemplary, this should not be construed as limiting. Further, it will be understood that the illustrated embodiments of the accessory


10


can be mingled, as desired.




Turning now to the method of creating the accessory


10


of

FIGS. 3 and 4

, it has been stated hereinabove they are created by injection molding.




Typically, when an item is to be created by injection molding, a two piece die is used, with the pieces of the die being held together by the application of pressure thereagainst. Crisp, clean lines are obtained in the molding process when the pressure of injection into the die of suitable material is maintained below the clamping pressure used to hold the pieces of the die together, or closed.




However, it has been observed that, upon increasing injection pressure and/or decreasing the clamping pressure holding the die closed to a level where the injection pressure is greater, the precision of the die casting can be overcome, providing the feathered edge


30


to the accessory


10


of

FIGS. 3 and 4

.




It has never previously been proposed to overcome die precision in this manner. Nor has creation of a feathered edge


30


been proposed using the above modified method of injection molding.




It will be understood that there is no way to control bleeding of the material between pieces of the die when the method described is used. Accordingly, each star


10


created by the method has a unique pattern of the feathers edge


30


of the flanges


22


.




As described above, the accessory and method of the present invention provide a number of advantages, some of which have been described above and others of which are inherent in the invention. Also, modifications may be proposed to the above disclosure without departing from the teachings therein. Accordingly, the scope of the invention is only to be limited as necessitated by the accompanying claims.



Claims
  • 1. An ornamental accessory incorporating a center throughbore defined with the accessory, the throughbore being sized and configured to frictionally engage the accessory onto a bulb of a string of lights, and the accessory comprising a plurality of planar radial arms protruding outwardly from and around said throughbore wherein each arm includes a center rib and a feathered flange extends laterally outwardly to either side of said rib.
  • 2. The accessory of claim 1 wherein the throughbore has nubs protruding inwardly thereinto.
  • 3. The accessory of claim 1 being planar and of a thickness to allow more than one accessory to be engaged onto the bulb.
  • 4. A method for creating the ornamental accessory of claim 1 comprising the steps of:producing a two piece die for the desired base configuration of the accessory; clamping the die closed through application of clamping pressure against the pieces of the die; and, injecting a suitable substance into the die at a pressure greater than the clamping pressure to allow the injected substance to bleed outwardly between the pieces of the die.
