Ring shank reinforcement

Abstract

A jewelry product whose ring shank is strengthened after ring sizing by securing a protective reinforcement plate made of a material to a recess in the ring shank. The ring shank is less susceptible to wear from abrasion than is the ring shank. The ring shank may have a decorative portion facing outwardly located diametrically opposite the recessed portion. An insert may be seated about the decorative portion.

Description

BACKGROUND OF THE INVENTION

The present invention relates to reinforcing or strengthening a ring shank.

It is known to adjust a ring shank size to fit on a wearer's finger. One conventional ring sizing process involves sawing the ring shank at a location diametrically opposite the decorative portion of the ring to form a cut, filing the ring shank at the cut until enough material is removed to attain a desired size of the wearer and then soldering together opposite sides of the cut.

The ring sizing process itself is known to cause physical changes to occur to the ring shank. For instance, there is usually a reduction in the shank dimension where the sizing process took place. Such reduction further weakens the ring shank than would otherwise be the case. The texture of the ring shank appearance may become altered in that it may no longer match as before, particularly if the sizing process causes the formation of visible solder seam lines, cold solder joints, incomplete solder joints or pits in the solder seam. Indeed, the inside contour of the ring may no longer be perfectly round after sizing.

It would therefore be desirable to form the ring shank in a manner to address undesired alterations to the ring shank appearance attributed to the ring sizing process. That is, to make provision for strengthening the ring shank after ring sizing and for hiding seams from view should they arise from the ring sizing process. It is further desirable to increase the wear of a ring shank by rendering it less susceptible to wear from abrasion.

BRIEF SUMMARY OF THE INVENTION

One aspect of the invention relates to formation of a recess in a metal ring shank. The recess has portions configured to engage with fasteners to secure a protective reinforcement plate to the recess. The plate should be of a harder metal than that of the ring shank. Its dimension is such that when positioned in the recess of the ring shank, it not only covers, strengthens and protects the underlying ring shank from wear due to abrasion, but also hides imperfections that may be present in the ring shank, such as seams that may remain as a result of the ring sizing process.

DETAILED DESCRIPTION OF THE INVENTION

Turning to the figures, FIG. 1 shows a ring 10 in accordance with the invention. The ring 10 includes a ring shank 12 made of a metal and a protective reinforcement plate 14 secured to the ring shank 12. The protective reinforcement plate 14 is made of a harder material than the ring shank 12 and is less susceptible to wear from abrasion than the ring shank 12, if at all. The protective reinforcement plate 14 may be secured to ring shank 12 by fasteners 16, such as screws. If desired, the protective reinforcement plate 14 may have raised or recessed lettering or other kinds of indicia. FIG. 2 shows an enlargement of the protective reinforcement plate 14 with fasteners 16.

FIG. 3 exemplifies a container or box 18 to contain the ring 10. The box 18 may have the protective reinforcement plate 14 of FIG. 2 (or an identical plate) secured to it.

FIG. 4 shows a ring 20 to which is tied the protective reinforcement plate 14. The protective reinforcement plate 14 is preferably elongated and has two holes or apertures 17 spaced apart from each other. The distance between the two holes or apertures 17 substantially matches the distance between threaded holes in the outer facing surface of the ring shank 12 so that they align to enable insertion of the fasteners 16 through the two holes or apertures 17 to secure to the ring shank 12 in the manner of FIG. 1. In FIG. 4, the tying may be done after ring sizing is complete to allow the wearer to try on the ring to verify proper sizing and fit before the protective reinforcement plate 14 is fastened.

FIG. 5 shows a ring shank 30 in accordance with a further embodiment. A recessed portion 32 is curved in a circumferential direction of the ring shank 12. The protective reinforcement plate 14 is configured to be bent or curved to fit onto the recessed portion 32. The recessed portion 32 includes threaded recesses 34 to receive the fasteners 16 exemplified by screws. The recessed portion 32 may be formed at the time the metal is cast for the ring or may be made later by filing material until a desired depth for the recess is attained to accommodate the thickness of the protective reinforcement plate 14.

FIGS. 6-8 show the manner of securing the protective reinforcement plate 14 to the recessed portion 32 with the fasteners 16. The two holes or apertures 17 of the protective reinforcement plate 14 (see FIG. 4) are spaced apart from each other to be substantially the same distance apart as, and thereby align with, the threaded recesses 34 when the protective reinforcement plate 14 is curved or bent to conform to the contour of the recessed portion 32. Diametrically opposite to the recessed portion 32 is a decorative portion 36. The decorative portion 36 may be made of precious metal or have a setting for retaining precious stones.

The ring shank 30 is cast using any conventional metal casting techniques. The protective reinforcement plate 14 is of different material from that of the ring shank 30 and is stamped using any conventional metal stamping techniques. The protective reinforcement plate 14 is screwed into the threaded recesses 34 in the underside of the ring shank 30 using a conventional jeweler's screwdriver.

The purpose of the protective reinforcement plate 14 is to reinforce the bottom of the ring shank 30, to protect the outer facing surface of the shank 30 and to cover any seam line after ring sizing. The purpose of the fasteners 16, such as screws, is to attach the protective reinforcement plate 14 to the ring shank 30 and to allow for removal of the protective reinforcement plate 14 before ring sizing.

After ring sizing, a new plate may be used that is sized to fit into the recessed portion 32 with holes or apertures drilled into it in alignment with where the threaded recesses 34 are positioned relative to each other. Alternatively, the same protective reinforcement plate 14 could be used, but it may be necessary to enlarge the holes to ensure alignment for the fasteners 16 with the threaded recesses 34.

The bottom of a ring shank 30 is the area that has greatest wear and potential damage from abrasion. By securing the protective reinforcement plate 14 to the recessed portion 32 with fasteners 16 in a releasable manner as described previously, the result will be a longer wearing ring. The ring shank 30 may be silver, the protective reinforcement plate 14 may be titanium, and the fasteners 16, such as screws, may be steel. Thus, both the ring shank 30 and the protective reinforcement plate 14 may be made of different kinds of metals, whether precious or non-precious metals.

As seen in FIGS. 9-14, the decorative portion 36 may be raised to seat a surrounding insert 38 in a seat 40. The seat 40 is adjacent a raised surface 42 that extends around the outer periphery of the decorative portion 36. The insert 38 may be friction fit on the seat or soldered or fastened with fasteners 16 to the ring shank, depending upon how one chooses to retain the insert 38 on the seat 40.

If desired, instead of the protective reinforcement plate 14 having two holes or apertures 17, it could have a single hole or aperture centrally located. Thus, the recessed portion 32 of the ring shank 30 may have a single formation centrally located and configured to align and engage with a single fastener 16 that extends through the one hole or aperture in the protective reinforcement plate 14.

While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the scope of the present invention.
