Unitary ring reducer
RELATED APPLICATION 
     This application is a continuation-in-part for U.S. patent application Ser. No. 08/224,530 filed Apr. 7, 1994, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to ring sizing devices and more particularly pertains to a unitary ring reducer for fitting a larger ring to a individual&#39;s smaller finger. 
     2. Description of the Prior Art 
     The use of ring sizing devices is known in the prior art. More specifically, ring sizing devices heretofore devised and utilized for the purpose of reducing the cross sectional area of a ring are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     For example, a finger ring and insert therefor is illustrated in U.S. Pat. No. 4,480,447 in which a saddle-shaped insert is fitted to the lower portion of a ring, with a leaf spring being provided between the ring and the insert to bias the insert radially inward. The insert preferably has depending tangs which can be bent around the outside edge of the ring to hold it in place. 
     Another patent of interest is U.S. Pat. No. 5,261,256 which teaches an instant flex ring guard or insert that is constructed of a soft flexible, low durometer thermoplastic rubber that will lay flat and affix to a bottom inside of a finger ring shank by means of adhesion. The device after installation remains flexible such that when a finger is inserted through the finger ring, the guard will flex out of the ring and then flex back into the finger ring when in position to constantly exert pressure against the finger keeping the ring from spinning on the finger. 
     Other known prior art ring sizing devices include U.S. Pat. No. 3,518,843; U.S. Pat. No. 4,916,924; U.S. Pat. No. 3,590,598; U.S. Pat. No. 3,237,426; U.S. Pat. No. 3,603,109; and U.S. Pat. No. 4,471,634. 
     While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a unitary ring reducer for fitting a larger ring to an individual&#39;s smaller finger which includes a ring conduit having a slot allowing a portion of a ring to be positioned within the conduit and a reducing web extending radially inward from the conduit to reduce the area of the ring and allow for the snug fit of a larger ring over a smaller finger, wherein the reducer may be customized to a particular individual by trimming the reducing web with a knife. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of ring sizing devices now present in the prior art, the present invention provides an improved unitary ring reducer. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved unitary ring reducer apparatus and method which has all the advantages of the prior art and none of the disadvantages. 
     To attain this, the present invention essentially comprises a ring reducer for fitting a larger ring to an individual&#39;s smaller finger. The reducer includes a ring conduit having a slot allowing a portion of a ring to be positioned within the conduit. A reducing web extends radially inward from the conduit to reduce the area of the ring and allow for the snug fit of a larger ring over a smaller finger. The reducer may be customized to a particular individual by trimming the reducing web with a knife. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1-4 thereof, a new unitary ring reducer embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the unitary ring reducer 10 comprises a reducing web 12 having a substantially arcuate web face 14 having a first radius of curvature and a substantially arcuate web inner wall 16 having a second radius of curvature, wherein the first radius of curvature is greater than the second radius of curvature. The reducing web 12 is operable to be positioned against a lower inner surface of a ring 18, as illustrated in FIG. 3. Because the first radius of curvature of the web face 14 is greater than the second radius of curvature of the web inner wall 16, the reducing web necessarily projects radially inward to effectively reduce the through-cross-section of the ring 18, thereby allowing the ring to accommodate a smaller finger than would be possible without the ring reducer 10. 
     To releasably couple the unitary ring reducer 10 to the ring 18, as illustrated in FIG. 3, a ring conduit 20 is provided. As best illustrated in FIGS. 2 and 4, it can be shown that the ring conduit 20 comprises a first side wall 22 and a second side wall 24 which are integrally formed with the reducing web 12 and extend radially outward from a center point 27 of the ring 18. Further, the side walls 22, 24 extend substantially parallel and coextensive relative one to the other, with the outer radial edges of the side walls being substantially arcuate in shape so as to follow the circular contour of the ring 18. 
     Integrally and orthogonally mounted to the respective side walls 22, 24 is a first outer wall 26 and a second outer wall 28. The outer walls 26, 28 extend laterally inward from the side walls 22, 24 to define a slot 30 coextensive with the outer walls. Thus, the inner web wall 16, the side walls 22 and 24, and the outer walls 26 and 28 cooperate to define a ring passage 32 within which a portion of the ring 18 may be captured, thereby mounting the reducing web 12 in the position illustrated in FIG. 3. The web 12 and the walls 22-28 are integrally formed of a substantially resilient polymeric material such that lateral deformation of the side walls in conjunction with radial deformation of the outer walls permits a portion of the ring 18 to be positioned within the ring passage 32, whereby the resiliency of the polymeric material will cause the walls to return to their original shape, in a shape retentive manner, to encapsulate and capture the portion of the ring within the passage 32. 
     In use, the unitary ring reducer 10 may be easily attached to a ring 18 as described above, thereby reducing the through-cross-sectional area of the ring to accommodate smaller fingers. In addition, the reducing web 12, because of its polymeric construction, may be trimmed with a knife or other sharp instrument to alter a contour of the web face 14 and provide a customized fit to a particular individual. 
     A second embodiment, as shown in FIG. 5 &amp; 6, comprises a spherical horizontally extending protrusion 34 formed along an end 35 of a first outer wall 36. Also included is a spherical inlet 38 formed along an end 39 of a second outer wall 40 for releasably receiving the spherical protrusion 34. 
     A third embodiment, as shown in FIG. 7, comprises a triangular horizontally extending protrusion 42 formed along an end 43 of a first outer wall 44. Also included is a triangular inlet 46 horizontally formed along an end 47 of a second outer wall 48 for releasably receiving the triangular protrusion 42. 
     A fourth embodiment, as shown in FIG. 8, comprises a first outer wall 50 overlapping a second outer wall 52. The first outer wall 50 comprises an upper surface 54, lower surface 56, an inboard end 58 connected to one side wall 60 and a free outboard end 62. The second outer wall 52 of the ring reducer comprises an upper surface 66, lower surface 68, an inboard end 70 connected to another side wall 72 and a free outboard end 74. The fourth embodiment further includes a circular protrusion 76 formed along the upper surface 54 of the outboard end 62 of the first wall 50. For coupling purposes, an inlet 78 is formed along the lower surface 68 of the inboard end 70 of the second outer wall 64 for releasably receiving the circular protrusion 76. 
     A fifth embodiment, as shown in FIG. 9, is constructed similar to the fourth embodiment with a first outer wall 80 overlapping a second outer wall 82 while lacking the protrusion and corresponding inlet. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
