Patent Application
20080314083
The present invention relates to a gemstone crown head with a notch in the bottom wall that attaches flush to an integral crossbar in a ring setting without the use of a lock or latch to hold the gemstone crown head in place. More particularly, this allows different sized gemstone crowns to be received by the same ring setting for mounting of different sized diamonds or gemstones.
Finger rings with interchangeable settings are well-known in the prior art. Such interchangeable settings include key and screw attachment assemblies, interchangeable ring shank and ring ornament assemblies having male and female mechanisms, an interchangeable setting with a slip and catch engagement means, a post and groove interchangeable setting, an interchangeable multiple mount head system, and the like. The problem with the above aforementioned assemblies and systems requires the jeweler to manipulate small parts in its assembly and the frustration of losing these small parts in the rings assembly. Other problems include having an interchangeable mechanism that is not easy to use, as well as being secure when the gemstone and crown head are mounted together. These custom assemblies many times lack mechanical integrity.
There remains a need for a universal ring setting for receiving different size gemstone crown heads for holding different size diamonds or gemstones. Further, the gemstone crown head has a notched groove in the bottom wall which attaches in a flush manner to an integral crossbar member in a ring setting without the use of a lock or latch in order to hold the gemstone crown head in place. Additionally, the gemstone crown head and the universal ring setting has an interchangeable mechanism that is easy to use, secure when attached with each other and does not require the jeweler to manipulate any small parts when assembling the ring.
Key and screw attachments for a crown and shank, interchangeable crown heads, interchangeable ring ornament assemblies, multiple mount head systems and the like having various designs, structures, configurations and materials of construction have been disclosed in the prior art. For example, U.S. Pat. No. 2,775,878 to EICHHORN discloses a ring comprising a shank that is recessed at the top to provide a crown seating portion with a radially directed hole and a transverse passage through the crown. The crown is removably fitted to the crown seating portion of the ring shank. The opposite side portions of the crown have openings through them that fit on the opposite ends of the transverse passage of the crown seating portion of the ring. A key is applied through the transverse passage of the ring to secure the crown to the shank. A jewel is set in the crown and a screw is applied outwardly through the radially directed hole in the crown seating portion of the shank, through the key, and threaded into the jewel setting. This prior art does not disclose or teach the design, structure and configuration of the universal ring setting for receiving different size crown heads of the claimed present invention.
U.S. Pat. No. 5,491,986 to WHITE discloses a jewelry item having an interchangeable crown capable of being attached to different jewelry items such as a ring, bracelet or necklace. The jewelry system includes a decorative crown which mounts on the bars of the item of jewelry which may be scaled in size to adorn a finger. The crown is retained on the ring shank by a retainer slide. This prior art does not disclose or teach the design, structure and configuration of the universal ring setting for receiving different size crown heads of the claimed present invention.
None of these prior art patents teach or disclose the design, structure and configuration of a gemstone crown head with a notch in the bottom wall that attaches in a flush manner to an integral crossbar in a ring setting for allowing different sized gemstone crown heads to be received by the same ring setting for mounting of different size gemstones.
Accordingly, it is an object of the present invention to provide a universal ring setting for receiving different size crown heads for holding and mounting different size gemstones or diamonds.
Another object of the present invention is to provide a gemstone crown head that has a notch in the bottom wall which attaches flush to an integral crossbar member in a ring setting without the use of a lock or latch to hold the gemstone crown head in place.
Another object of the present invention is to provide a gemstone crown head that can vary in size. This allows the crown head to be received by the same ring setting for mounting of different sized gemstones or diamonds.
Another object of the present invention is to provide a gemstone crown head that is easily installed and mounted to a universal ring setting.
Another object of the present invention is to provide a gemstone crown head and a universal ring setting having an interchangeable mechanism that is easy to use, secure and does not require the jeweler to manipulate any small parts which can be lost.
Another object of the present invention is to provide a gemstone crown head in conjunction with the universal ring setting such that the interchangeable mechanism exhibits mechanical integrity.
Another object of the present invention is to provide a gemstone crown head and the universal ring setting which are both durable and easy and inexpensive to replace if broken.
Another object of the present invention is to provide a gemstone crown head and a universal ring setting having an integral crossbar member that can be mass-produced in an automated and economical manner and is readily affordable by the consumer and/or jeweler.
In accordance with the present invention, there is provided a universal ring setting for receiving different size gemstone crown heads for mounting different size diamonds or gemstones. The universal ring setting includes a gemstone crown head for supporting a gemstone. The crown head includes a housing having a plurality of holding prongs, and an interior cavity for receiving and mounting the gemstone therein, and having a bottom circular edge with a notch formed therein. The universal ring setting also includes a ring shank for encircling a finger of a user, the ring shank has an upper shank section with an integrally attached crossbar member thereon. The crossbar member is used for detachably receiving the notch of the crown head thereon for cooperatively mounting of the crown head to the upper shank section of the ring shank.
Further objects, features and advantages of the present invention will become apparent upon the consideration of the following detailed description of the presently preferred embodiment when taken in conjunction with the accompanying drawings, wherein:
a to 4e are top plan views of the gemstone crown head of the present invention showing a plurality of gemstone crown heads increasing in size for holding of different size gemstones;
The universal ring setting 10 and its major component parts of the preferred embodiment of the present invention is represented in detail by
As shown in
The universal ring setting 10 includes a ring shank 40 having an upper shank section 42 with an integrally crossbar member 44 formed thereon. Opposing ends 45a and 45b of the crossbar member 44 are integrally attached onto opposing ends 43a and 43b of the upper shank section 42 for forming the ring shank 40 of the universal ring setting 10. The crossbar member 44 is used for detachably receiving the notch 32 of crown head 20 for cooperatively mounting of the crown head 20 to the upper shank section 42 of ring shank 40, as shown in
As shown in
If the buyer decides to purchase a larger or smaller diamond 12, the jeweler then selects a larger or smaller gemstone crown head 20 in order to mount the diamond 12 to that sized crown head 20, as depicted in
Accordingly, an advantage of the present invention is that it provides for a universal ring setting for receiving different size crown heads for holding and mounting different size gemstones or diamonds.
