Sizable titanium ring and method of making same
A sizable ring and method of fabricating the same is disclosed. A first version comprises a first ring member, made of a hard metal (e.g., titanium), having a protrusion at each end thereof. The protrusions engage a second ring member made of a soft precious metal. The ring may then be sized in a conventional manner by cutting through the second ring member and adding or removing precious metal. In a second version, a link member includes pins at each end which engage openings or cavities in ends of one or more additional ring members. Other versions include rings with multiple link members. The methods disclosed herein are ideal for titanium rings.
The embodiments of the present invention relate to a sizable ring. More particularly, the embodiments relate to a sizable titanium ring permitting the ring to be re-sized rather than requiring a wearer to have a new ring fabricated.
BACKGROUNDAs the use of titanium for rings has increased, re-sizing them has become a critical issue. Heretofore, titanium rings have not been re-sized but have been replaced or remade. This is especially true in the event that the ring needs to be reduced in size. The hardness of the titanium makes conventional re-sizing methods generally useless. Therefore, titanium rings are often sold with a warranty fee including an exchange program. Under such a program, a customer drops off the ring requires re-sizing at the jewelers and the jeweler returns it to the manufacture. The manufacture then replaces the ring with a new ring or remakes a new properly-sized ring. Completing the exchange and return process can take several weeks causing customers to become frustrated and angry.
To accommodate customers many jewelers maintain a large inventory of each titanium ring they carry, including multiple sizes so that the jewelers have a suitable number of rings to serve as replacements. However, such a large ring inventory can become a financial drain on a jeweler's resources.
Thus, there continues to be a need for a sizable titanium ring which eliminates the need for the current process of replacement and/or the necessity of carrying a large inventory of rings.
SUMMARYAccordingly, a first embodiment of the present invention comprises a first ring member forming a partial ring having two ends, said first ring member fabricated of a hard metal; a protrusion extending from each end of the first member; and a second ring member comprising a soft metal, said second member integrally formed with said first member by means of the protrusions thereby forming a complete ring.
Sizing the ring of the first embodiment is accomplished in a conventional manner. That is, a cut is made through the second member, more soft metal is added and a heat source (e.g., torch) is used to reform the enlarged ring. To reduce the size of the ring, a portion of the soft metal is removed before reforming the ring with the torch. Such a method is ineffective with a full titanium ring because titanium is many magnitudes harder than a soft metal (e.g., gold or silver) which makes cutting through it, and re-forming it with heat, very difficult, if not impossible.
Accordingly, a second embodiment of the present invention comprises a first titanium ring member forming a partial ring having two ends with each end having an aperture therethrough; and a link having a pin at both ends thereof, said pins for engagement with said apertures at ends of the first titanium member such that said link joins said two ends to one another to form a ring. In one embodiment, the link joins the two ends near a shank of the completed ring while a portion of the ring opposite the shank retains a diamond or other gem. Alternative designs are disclosed herein.
With the second embodiment of the present invention, a ring is re-sized by changing the link. Thus, for a larger ring, a longer link is installed, and for a smaller ring, a shorter link is installed. Changing the links may take minutes as opposed to weeks for the exchange and replacement techniques used currently.
Since titanium is not a precious metal, it does not possess an inherent value like that associated with precious metal rings. Therefore, manufacturing at least some portion of the ring (e.g., the link) of gold, silver or some other precious metal creates a titanium ring having inherent value. The color of the precious metal used to fabricate the link may also create a unique color pattern serving as an identifiable feature of rings utilizing the embodiments of the present invention. For example, a black titanium ring utilizing a gold link is readily identifiable as a ring fabricated according to the embodiments of the present invention thereby creating immediate recognition for such unique rings.
Other variations, embodiments and features of the present invention will become evident from the following detailed description, drawings and claims.
BRIEF DESCRIPTION OF THE DRAWINGS
For the purposes of promoting an understanding of the principles in accordance with the embodiments of the present invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive feature illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention claimed.
Although titanium is used throughout this detailed description, other hard metals may benefit from the invention disclosed herein.
Reference is now made to the figures wherein like parts are referred to by like numerals throughout.
Fabricating the ring 100 comprises casting the first titanium ring member 110 and molding the second ring member 120 into the space defined by the two ends of the first ring member 110. Accordingly, a molten soft metal (e.g., gold or silver) is molded in place between the two ends of the first ring member 110 such that when it cures or dries it does so over the shaft and ball structure 140. Thus, the shaft and ball structure 140 secure the second ring member 120 in place.
To re-size the ring shown in
Now referring to
The link 350 is shown individually in
Fabricating the link 350 comprises casting or otherwise forming the titanium core 370 with one or more openings 380 therethrough as shown in
By making multiple first members 310, second members 320 and links 350, re-sizing and configuring rings of any size becomes an easy process. Accordingly, the time constraints associated with titanium ring re-sizing are eliminated and jewelers are able to undertake the work on site.
As shown in
The ring designs herein also allow emergency personnel to remove rings, in an emergency, without having to ruin them. That is, cutting off a conventional hard metal ring will leave it permanently damaged. Using the designs disclosed herein allow the emergency personnel to cut through the soft metal portion thereby permitting the ring to be easily repaired in the traditional manners set forth herein.
Although the invention has been described in detail with reference to several embodiments, additional variations and modifications exist within the scope and spirit of the invention as described and defined in the following claims.
