Abstract
Abstract An ornamental article such as a pearl necklace has a plurality of gem objects each having a spherical surface and a through hole extending substantially perpendicularly to the spherical surface, a string threaded through the gem objects to interconnect them, and a plurality of spacers of an elastomeric material interposed between adjacent ones of the gem objects and having through holes through which the string extends. Each of the spacers has a thicker central portion and a thinner outer circumferential edge. The spherical surface of each of the adjacent gem objects has a radius of curvature of r. The thicker central portion having a thickness of at most 0.4r, each spacer having a radius of at most 0.77r. With this arrangement, the gem objects can easily be threaded on the string. The string is prevented from being subjected to undue tension even when bent strongly, so that the string and the gem objects are projected against damage in use or sale.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
An ornamental article comprising: a plurality of objects each having a spherical outer surface defined by a radius r and a first aperture means defining an aperture extending through each object substantially perpendicular to said spherical outer surface; string means threaded through the first aperture means for interconnecting the objects; and a plurality of generally discus shaped spacers each spacer having an axis and a circular perimeter defined by a radius transverse to the axis and a central portion having a maximum thickness measured along the axis; and a second aperture means defining an aperture extending through the central portion along the axis for receiving the string means, at least one spacer interposed between adjacent objects, and wherein the perimeter radius measured from the axis is no greater than 0.77r and the maximum thickness is no greater than 0.4r.
