FIELD OF THE INVENTION
The present invention relates generally to an article of jewelry, and more specifically to a ring wherein an ornamental article displayed by the ring may be easily replaced by another ornamental article.
BACKGROUND OF THE INVENTION
The desirability of articles of jewelry, such as rings, pendants, earrings, bracelets, or broaches with interchangeable settings has long been evident in the art. Being interchangeable the setting can be matched to other articles of jewelry, clothing or accessories.
DISCUSSION OF THE PRIOR ART
Over one hundred years ago a ring provided using a set screw to facilitate the use of interchangeable stones in a setting was disclosed by W. R. Elliot in U.S. Pat. No. 899,296. Since then many articles of jewelry having interchangeable ornamental articles have been disclosed with varying degrees of commercial success, as evidenced for example by U.S. Pat. Nos. 1,186,271; 1,152,340; 1,326,977; 3,115,758; 3,653,227; 4,742,696; 4,794,766; 5,077,989; 5,606,874; 5,996,374; 6,131,408; 6,427,487; 6,490,886; 6,601,408; 6,701,747; 6,711,915; 6,715,314; 6,729,159; 7,143,607; 7,222,503, 7,322,212; D 563,821; and D 576,909.
While most articles of jewelry providing for interchangeable ornamental articles have a single ring shaped member, there are a few publications that disclose jewelry articles having more than one cooperating ring members.
U.S. Pat. No. 6,318,122 B1 discloses an interchangeable a rotatable jewelry display for beads or ornaments. The jewelry apparatus has a sole shaft for interchangeably displaying and rotating at least one ornament and a retainer comprising a first ring section and a second ring section. The first ring section has a sole shaft positionally disposed on the first ring section for interchangeably receiving and holding the ornament and allowing the ornament to rotate around the shaft. The second ring section has at least one arm for receiving the shaft of the first ring section and a catch slideably and rotatably inserted onto the shaft of the first ring section. The first ring section may be rotated away from the second ring section to facilitate the interchanging of various ornaments.
U.S. Pat. No. 6,715,315 B1 and U.S. Pat. No. 7,201,021 B2, which is a divisional thereof, disclose an article of jewelry having two adjoining ring members, referred to therein as “body portions” wherein the body portions are magnetically coupled to one another when the body portions are aligned with one another. At least one of the body portions is rotatable to tangentially break the magnetic coupling between the body portions to tangentially break the magnetic coupling between the body portions to interchange a setting. In another aspect of that invention magnetic elements are used to magnetically suspend a movable setting on a jewelry article.
U.S. Pat. No. 5,228,317 discloses a ring having two “ring shanks” that pivot around a pin parallel to the finger holes through the two “ring shanks”. One of the “ring shanks” has a gem set receiving hole which receives a center gemstone prong setting when the two shanks are in an open position. When a center gemstone prong setting containing a center gemstone and a prong setting base is introduced into the gem setting hole and the two “ring shanks” are moved to their closed position, the escape path for the center gemstone prong setting is blocked and the center gemstone prong setting is locked in place. Locating a pivot pin closely adjacent to the setting provides a mechanical advantage to carry loads of large bezels and/or gemstone clusters around a replaceable or interchangeable centered gemstone.
FIGS. 1 and 2 of the present document show a ring 300 designed by the applicant of the present application and marketed as the “over the top ring embracer” presented on the applicant's web site: www.marilujewelrydesign.com. A frame member 312 has two spaced apart parallel rings 313, 314 that are fixed to one another at only one location 315. A circular portion 324 of a ring insert 323 is placed into a space 316 between the spaced apart parallel rings of the frame member. The separate ring insert has an ornamental article 321, shown in the figures as a genuine or artificial gemstone, permanently mounted thereto. A wire or pin 335 extends between two protrusions 332, 334 of the ring insert 323 and is circumferentially aligned with and radially outward of the permanently mounted ornamental article 321, spaced apart from the ornamental article and not contributing to the retention of the permanently mounted ornamental article. If it is desired to change the appearance of the “over the top ring embracer” by having a different ornamental article it is necessary to obtain a different ring insert provided with a permanently mounted ornamental article of a differing appearance, since the ornamental articles alone are not interchangeable in the setting of the ring.

DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention is shown in FIGS. 3-6 and 8-10. While the articles of jewelry shown in the figures for each of the embodiments is a ring for wearing on a persons finger, it is to be understood that an article of jewelry of the present invention could be a bracelet, a pendant, a brooch, or an earring. An article of jewelry 10 has a frame member 12 and a securing member 23. The frame member comprises two spaced apart parallel rings 13, 14 that are permanently fixed to one another only at a first location 15. At a second location diametrically opposed to the first location 15 each of the spaced apart parallel rings 13, 14 has a pedestal 17, 18 integral therewith. It is understood that the size and shapes of the pedestals may vary to suit the practical and aesthetic tastes of a manufacturer and consumer of a jewelry article of any of the embodiments the present invention disclosed herein. As used herein and in the claims the term “pedestal” is understood to have its ordinary meaning of a supporting structure or piece. Each of the pedestals 17, 18 has a notch 19, 20 therein at an edge of the pedestal adjacent a space 16 separating the parallel rings 13, 14. As used herein and in the claims the terms “notch” and “notches” are understood to have their ordinary meanings of an angular cut, indentation, or hollow in an object, surface or edge. The pedestals and notches are circumferentially aligned to cooperate with one another to provide a seat for seating an ornamental article 21 therein. The seat for receiving a complementary portion of an ornamental article 21 is therefore not one continuous surface, but rather is provided by the surfaces of the two notches separated by the space 16 between the two parallel rings 13, 14.
The securing member 23 secures the ornamental article 21 to the frame member 12. The securing member is a ring 23 inserted in the space 16 between the parallel rings 13, 14 of the frame member 12 in a movable manner. That is to say, the securing member is disposed in the space between the parallel rings of the frame member and is movable with respect to the parallel rings of the frame member. The securing member 23 is provided with a means 25 for securing the ornamental article 21 seated in the pedestals 17, 18 and notches 19, 20 of the frame member when the means for securing is aligned with the pedestals and notches of the frame member. In the first embodiment the means for securing 25 is a bezel oriented, shown oriented perpendicular to the ring 23. As used herein and in the claims the term “bezel” is understood to have its ordinary meaning of a ring or rim holding a gem or other ornamental article in its setting. The securing member 23 is inserted in the space 16 between the parallel rings 13, 14 of the frame member 12 in a movable manner wherein the means 23 for securing the ornamental article 21 may either be aligned with the pedestals and notches of the frame member to cooperate with the frame member for securing the ornamental article seated in the pedestals and notches of the frame member, or the securing member may be moved with respect to the frame member displacing the means 23 for securing the ornamental article 21 to allow the ornamental article to be removed from the pedestals and notches of the frame member and replaced by another ornamental article.
It is understood that the frame member 12 and the securing member 23 may comprise any suitable material, or materials, selected to suit the practical and aesthetic tastes of a manufacturer and consumer of a jewelry article of any of the embodiments the present invention disclosed herein. Such materials include for example metals and alloys thereof, and polymers. The frame member and securing member may comprise the same or different materials. It is understood that the frame member and securing member may be fabricated without undue experimentation by those skilled in the art of making article of jewelry using any suitable and well known methods including casting, molding, welding, soldering, machining, bending, and so forth.
It is understood that the shape and size of an ornamental article for an article of jewelry of the present invention may vary to suit the practical and aesthetic tastes of a manufacturer and consumer of a jewelry article of any of the embodiments the present invention disclosed herein. It is further understood that the composition and color of an ornamental article for an article of jewelry of the present invention may vary to suit the practical and aesthetic tastes of a manufacturer and consumer of a jewelry article of any of the embodiments the present invention disclosed herein. For example the ornamental article may be a genuine or artificial gemstone, or a ceramic, or a polymer, or a metal. In the embodiments shown in the figures the ornamental article is an artificial gemstone. It is anticipated that an article of jewelry according to the invention may be marketed with a supply of variously colored artificial gemstones, all of which are sized and shaped to be complementary with the sizes and shapes of the corresponding pedestals, notches and means for securing the ornamental article in the notches that are a setting for the ornamental article.
In the article of jewelry 10 of the first embodiment the securing member 23 is fixed to the frame member 12 by a pivot pin 26. As best shown in FIG. 6, the pivot pin 26 passes through: a hole 28 in one of the parallel spaced apart rings 13 of the frame member 12; a hole 30 in a protrusion that extends from the ring 24 of the securing member 23; and a hole 29 in the other of the parallel spaced apart rings 14 of the frame member 12. The pivot pin 26 has an enlarged head at one end for engaging a ring 13 of the frame member 12, and a cap 27 is fixed to the other end of the pivot pin adjacent the other ring 14 of the frame member to secure the pivot pin in its operative position. The resultant structure is like a door hinge that enables the securing member to be pivoted with respect to the frame member as indicated by the arrows in FIGS. 5A and 5B, allowing the ornamental article 21 to be removed from the notches 19, 20 and be replaced by another ornamental article. The securing member can then be pivoted back into alignment with the parallel spaced apart rings of the frame member with the means for securing the ornamental article seated in the pedestals and notches, in this embodiment the bezel 25 is once again positioned to secure the ornamental article in place. While the location of the pivot pin may be varied, it worked well at the location shown near the pedestals in the figures.
It is to be understood that features of the invention such as the shapes of the pedestals 17, 18, the dimensions of the frame member 12, the sizes and shapes of the notches 19, 20 to be complementary to the size and shape of the ornamental article 21, and so forth may be varied to meet the needs and aesthetic tastes of the manufacturer and consumer of articles of jewelry according to the invention.
In each embodiment of an article of jewelry disclosed herein the securing member and the frame member, including the space between the parallel spaced apart rings of the frame member, are dimensioned such that the securing member adjoins the frame member with friction resisting relative movement of the securing member with respect to the frame member.
An article of jewelry 40 according to a second embodiment of the invention is shown in FIGS. 7, 11 and 12. The second embodiment is substantially like the first embodiment comprising a frame member 42 and a securing member 46. The frame member comprises two spaced apart parallel rings 43, 44 that are permanently fixed to one another only at a first location 45. The securing member is fixed to the frame member by a pivot pin 52 as in the first embodiment, and the article of jewelry secures an ornamental article 53 in a replaceable manner as described above for the first embodiment. However, the second embodiment further comprises a means for restricting movement of the securing member 46 with respect to the frame member 42 in a releasable manner when the means for securing the ornamental article is securing the ornamental article seated in the pedestals and notches of the frame member. A well 47 in the portion 45 of the frame member 42 securing the spaced apart parallel rings 43, 44 to one another contains a coil spring 48 that bias a sphere 49 towards the center of the frame member and engages a shallow detent 50 in a circumferentially extending outer surface of the securing member 46 as best shown in FIG. 11. When the securing member 46 is pivoted a sufficient angle α to allow the removal and insertion of the ornamental article 53 in the frame member, as shown in FIG. 12 the sphere is urged towards the center of the frame member, but only with a relatively minor force. When the securing member is pivoted back to have the means for securing engage the ornamental article and retain it in place, the securing member urges the sphere 49 away from the center of the frame member with the sphere engaging the detent 50 in the circumferentially extending outer surface of the securing member 46. This means for restricting movement of the securing member 46 with respect to the frame member 42 in a releasable manner may be incorporated in any of the embodiments disclosed herein, and supplements the friction between the securing member and the rings of the frame member to restrict relative movement of these parts when the article of jewelry, such as a ring, is not being worn.
