Description

The present invention relates to a stone frame for jewelry.

Various types of stone frames have been disclosed for conventional jewelry, which increase the brilliance of jewelry by securing incident light from the pavilion side without processing the jewelry ( For example, see claim 2 of Patent Document 1, Patent Document 2, and Patent Document 3).
However, when such a stone frame has a structure in which the jewel is fixed with two ball chains as claimed in claim 2 of Patent Document 1, the large balls interfere with the design of the jewel itself, and the stone frame is insufficient. There was a problem in that it was not possible to ensure sufficient gem retention power. Further, with respect to a structure made of a thin wire body as in Patent Document 2, although sufficient jewelry holding power is ensured, there is a problem in that a claw portion is required and the installation process takes time. Furthermore, as in Patent Document 3, where the structure has pillars, arches, and an opening surrounded by these, although the opening secures a certain amount of light entering the pavilion, it does not secure enough light to enter the pavilion. There was a problem in that the arch part needed to be carefully bent in order to hold it. Further, Patent Document 2 and Patent Document 3 have a problem in that the jewelry may be damaged during processing to hold the jewelry.

Embodiments of the stone frame according to the present invention will be described below with reference to the drawings.
In the present invention, the term "girdle" is defined as a protruding part of a jewel that has the largest diameter when viewed from the front or above.
"Jewels" shall include imitation jewels as well as natural jewels.
A "stone frame" is defined as a frame for holding jewelry. In other words, it is a frame that directly fixes and protects naked jewelry for use as jewelry.
"Short within the range that can be elastically deformed" is defined as being shorter than the length of the comparison object within the range that can be elastically deformed to the length of the comparison object. In other words, when the target gemstone is fitted into the stone frame, the stone frame elastically deforms in the longitudinal direction and becomes longer, so that the length of the stone frame is the diameter of the gemstone being compared x 3.14 ( It is short enough that the diameter of the stone frame can be the diameter of the jewel. At this time, the stone frame is long enough to be elastically deformable, so after it is fitted, the stone frame elastically returns and becomes shorter, fixing the jewel and holding the jewel firmly.
"Short in the range that can be elastically deformed after plastic deformation" is defined as being shorter than the length of the comparison object within the range that can be plastically deformed and then elastically deformed to the length of the comparison object. First, the original metal chain is plastically deformed by enlarging its diameter (the metal chain after connecting the left and right ends), and the diameter of the metal chain is reduced to a length that is ``short within the range that can be elastically deformed'' (i.e., the metal chain after connecting the left and right ends). (as short as possible to be the length of the comparison target). After that, as mentioned above, when fitting a gemstone into a stone frame, it is elastically deformed so that the length of the stone frame is the length of the comparison object x 3.14 (the diameter of the stone frame is the length of the gemstone). diameter). Such is the length of the original metal chain.
A "metal chain" is defined as a metal chain, that is, a string-like thing made by connecting metal rings.
"Metal" is defined to include precious metals, non-precious metals, and alloys thereof.
A "piece" is defined as an individual annular element of a metal chain.
"Ellipse" is defined as a shape that can generally be recognized as an ellipse. That is, it includes an ellipse with a geometrically defined shape and an ellipse with a straight line part, such as the shape of a competition track. Geometrically defined, an ellipse is a curve made from a set of points whose sum of distances from two fixed points (focal points) on a plane is constant. That is, the shape looks like a circle crushed evenly up and down (or left and right).
"Longitudinal length" means the length of the metal chain in the longitudinal direction when the metal chains are connected to form a ring shape, and when the metal chains are not connected.
"Substantially equal" means that the length of the 16 sides of the girdle is such that the length of the metal chain in the longitudinal direction when 16 pieces are connected is shorter than the diameter of the jewelry x 3.14 within the range that can be elastically deformed. It is defined as approximately equal to the length of each side.
A "series of metal chains" is defined as a vertically long metal chain whose left and right ends are not connected.
The term "approximately" in approximately circular and approximately elliptical shapes does not necessarily mean that they are perfect circles or that they are elliptical shapes that are perfectly symmetrical in the horizontal and vertical directions.

[About the structure and shape of the stone frame of the present invention]
The structure and shape of the stone frame of the present invention are as follows.

<Configuration 1>
The main stone frame targets a gemstone with a girdle, and has an annular shape that connects the left and right ends of a metal chain made up of an even number of pieces so that it can be fitted into the girdle of the target gemstone. The length is shorter than the diameter of the target jewel x 3.14 within the elastic deformable range.
Further, each piece of the metal chain has a substantially circular shape or a substantially elliptical shape having a long axis in the longitudinal direction, and has the same length in the longitudinal direction.
As described above, configuration 1 is a stone frame configuration in which the target gemstones are limited to gemstones having girdles.
As mentioned above, the shape of each frame may be approximately circular or approximately elliptical. That is, all the pieces may be substantially circular, all the pieces may be substantially elliptical, or each piece of a series of chains may be a combination of substantially circular and substantially oval shapes. In this way, each frame does not need to have the same shape, but the length in the longitudinal direction needs to be the same as described above.

Also, based on the above configuration and shape, the target gemstone, that is, the gemstone to be fitted into the main stone frame, is a round brilliant cut gemstone a with 58 sides (57 sides if the culet is not chamfered; the same applies hereinafter). The shape and configuration in this case are as follows.
<Configuration 2>
The main stone frame is basically a stone frame having the structure and shape of Configuration 1, but the target gemstone is a round brilliant cut gemstone with 58 faces.
In addition, the even number of pieces in Configuration 1 is 16 pieces in Configuration 2, which matches the number of sides of the girdle of the above-mentioned jewel, and the length in the longitudinal direction of each piece of the 16 pieces is the length of the above-mentioned jewel. The length is approximately equal to the length of each of the 16 sides of the girdle.
In this way, Configuration 2 is a stone frame configuration based on Configuration 1 in which the target gemstone is specified and limited to a 58-sided round brilliant cut gemstone.
Note that the stone frame according to Configuration 2 is one of the specific examples of Configuration 1, and the stone frame of the present invention is suitable for round brilliant cut gemstones other than round brilliant cut gemstones with 58 sides or 16 sides of the girdle. It can also be applied to In this case, it is preferable that the even number of pieces in Configuration 1 be matched to the number of sides of the girdle, and the length of each piece in the longitudinal direction be approximately equal to the length of each side of the girdle.

<Configuration of this embodiment>
As shown in FIG. 1, the stone frame 1 according to this embodiment takes up the structure of Structure 2 as a specific example for easy understanding. That is, the target gemstone is a 58-sided round brilliant cut gemstone a, which is commonly used for cutting diamonds and the like. The jewel a has a girdle b as shown in FIG. 4(A). Since the girdle b has 16 sides as shown in FIG. 4(B), the number of pieces in the stone frame is also 16 since each side is guarded with one piece. Therefore, compared to Configuration 1, the number of frames and the length of each frame in the longitudinal direction are limited as described above.
The main stone frame 1 according to this embodiment is an annular metal chain having an even number of pieces, that is, 16 pieces, and whose left and right ends are connected. By fitting each piece into each side, the girdle b portion of the jewel a is fitted into the main stone frame 1.
In addition, so that the entire jewel a is fitted into the main stone frame 1, the length in the longitudinal direction of the main stone frame 1 is shorter than the diameter of the target jewel a x 3.14 within the elastic deformable range. There is. That is, when the jewel a is fitted into the main stone frame 1, it is shorter than the length of the diameter of the jewel a x 3.14 within a range that can be elastically deformed to a length of the diameter of the jewel a x 3.14.
As will be described later, when fitting the jewel a into the main stone frame 1, the stone frame 1 is lengthened within the elastically deformable range and fitted, so after being fitted, the stone frame 1 elastically returns and becomes shorter, making the jewel a shorter. Fix a and hold the jewelry firmly.
Furthermore, each piece of the metal chain is approximately circular in shape, as shown in each figure, and the length in the longitudinal direction of each piece is approximately equal to the length of each of the 16 sides of girdle b. They are the same length.
As described above, in this embodiment, the shapes of all the pieces are approximately circular, but this is just one example; as mentioned above, each piece may be approximately circular or approximately elliptical. The shape of each piece of the chain does not have to be the same.

[Stone frame manufacturing method of the present invention]
The stone frame manufacturing method of the present invention is as follows.

<Manufacturing method 1>
This manufacturing method is a manufacturing method for the stone frame of configuration 1 or configuration 2.
First, as step 1, the length in the longitudinal direction is shorter than the diameter of the target gemstone x 3.14 within the elastically deformable range, and is composed of an even number of pieces, each piece having a shape of approximately circular, Alternatively, a series of metal chains are created that are approximately elliptical in shape with the major axis in the longitudinal direction and have the same length in the longitudinal direction.
As mentioned above, the shape of each frame may be approximately circular or approximately elliptical. That is, the shape of each piece of the series of metal chains does not need to be the same, although the shape of each piece may be approximately circular or approximately elliptical. However, the lengths in the longitudinal direction need to be the same.
In step 2, the left and right ends of the metal chain in step 1 are connected to form a ring.
In step 3, the metal chain from step 2 is placed into a core rod c and shaped into a circle.
Step 4 is to solidify the metal chain from Step 3 into a circular shape by brazing or laser welding.
This is the method.

In view of the above manufacturing method 1, it is difficult to accurately set the length in the longitudinal direction to be shorter than the diameter of the target gemstone x 3.14 times within the elastic deformable range in step 1. Therefore, considering that it is easy to adjust the length of approximately circular or approximately elliptical pieces by plastic deformation and elongation in the longitudinal direction, we have set up a manufacturing method (manufacturing method 2) that takes plastic deformation into account as shown below. ing.
<Manufacturing method 2>
This manufacturing method is a manufacturing method for the stone frame of configuration 1 or configuration 2.
First, as step 1, the length in the longitudinal direction is shorter than the diameter of the target gemstone x 3.14 within the range that can be elastically deformed after plastic deformation, and it is composed of an even number of pieces, and each piece has a shape. , a series of metal chains that are approximately circular, or approximately elliptical with a long axis in the longitudinal direction, and have the same length in the longitudinal direction.
In step 2, the left and right ends of the metal chain in step 1 are connected to form a ring.
In step 3, the metal chain from step 2 is placed into a core rod c and shaped into a circle.
As step 4, the metal chain from step 3 is solidified into a circular shape by brazing or laser welding.
As step 5, the diameter of the metal chain from step 4 is expanded to a diameter shorter than the diameter of the jewelry within an elastically deformable range using a core metal rod c.
This is the method.

<Manufacturing method of this example>
The stone frame manufacturing method according to this embodiment shows a method of manufacturing the stone frame 1 of configuration 2 by manufacturing method 2.
Specifically, this manufacturing method is as follows.

First, in step 1, a series of metal chains 101 (metal chains whose left and right ends are not connected) as shown in FIG. 2A is created.
The length in the longitudinal direction of this series of metal chains 101 is shorter than the diameter of the target jewel a x 3.14 within the range that can be elastically deformed after plastic deformation. The length in the longitudinal direction (the diameter of the annular metal chain after the left and right ends are connected) can be adjusted by plastic deformation in step 5 (FIG. 3A), which will be described later, so it can be short at the plastic deformation level. Further, after the plastic deformation, when the jewel a is fitted into the stone frame 1 as described in configuration 2, it can be elastically deformed to a length of the diameter of the jewel a x 3.14. Therefore, in the end, the length in the longitudinal direction as a whole may be shorter than the diameter of the target jewel a x 3.14 within the range in which elastic deformation is possible after plastic deformation. The reason for this will be explained in step 5 below.
This series of metal chains 101 has an even number of pieces, that is, 16 pieces. Further, as shown in each figure, each frame has a substantially circular shape, and each frame has the same length. Further, since this embodiment is based on configuration 2, the length of each piece in the longitudinal direction is approximately equal to the length of each of the 16 sides of girdle b.
As described above, in this embodiment, the shapes of all the pieces are approximately circular, but this is just one example; as mentioned above, each piece may be approximately circular or approximately elliptical. The shape of each piece of the chain does not have to be the same.

In step 2, as shown in FIG. 2B, the left and right ends of the metal chain in step 1 are connected to form a ring (metal chain 102). Since the number of links is an even number (16 in this example), the left and right ends of the metal chain are in a positional relationship that intersects with each other, allowing connection.

In step 3, as shown in FIG. 2C, the metal chain from step 2 is placed into a core bar c (indicated by the broken arrow in the figure) and shaped into a circle.

In step 4, the metal chain in step 3 is solidified into a circular shape by brazing or laser welding (metal chain 103).

As step 5, as shown in FIG. 104).
Position 1(d) shows the original (process 4) state of the metal chain 103, which is the state before being expanded. Position 2(e) shows the state of the metal chain 104 after being unrolled in step 5.
The metal chain 103 fitted to the core rod at position 1(d) can be lowered to position 2(e) by, for example, placing a wooden plate on top of the metal chain and hitting the top of the wooden plate with a hammer or the like. The diameter is expanded by Here, the metal chain 103 needs to be deformed to a level of plastic deformation that prevents it from returning to its original diameter through elastic deformation.
A substantially circular or substantially elliptical top has the property of being easily plastically deformed and elongated in the longitudinal direction, and its length can be easily adjusted.
In other words, by enlarging the diameter using the above-mentioned method, each piece having a substantially circular (or substantially elliptical) shape is plastically deformed in the longitudinal direction and becomes more elliptical (as if it had been crushed from a direction perpendicular to the longitudinal direction). (shape), the metal chain becomes longer (diameter increases). The diameter of the metal chain 104 after plastic deformation is "shorter within the elastically deformable range" than the diameter of the stone frame 1 of the present invention, that is, the diameter of the jewel a.
As will be described later, when fitting the jewel a into the main stone frame 1, by elastically deforming and elongating the diameter in step 5, the diameter of the jewel a x 3.14, that is, the diameter of the metal chain 104, becomes the jewel. It becomes equal to the diameter of a.
The metal chain 104 is removed from the state shown in FIG. 3(A), and the stone frame 1 shown in FIG. 3(B) is completed.

[Method for holding jewelry using the stone frame of the present invention]
The jewel a is fitted into the stone frame 1 in the direction of the arrows shown in FIGS. 4A and 4B.
Position the girdle so that the jewel a is placed in the main stone frame 1 one frame at a time on each side of the girdle so that the state shown in Fig. 4 (C) and (D) (the state in which the jewel a is held by the stone frame 1) is achieved. I will fit it into. Since the diameter of the stone frame 1 of the present invention is "shorter within the elastically deformable range" than the diameter of the jewel a, the stone frame 1 is finally fitted with a longer length within the elastically deformable range.
Since the pieces of the stone frame 1 of the present invention are substantially circular or elliptical, they are easily elastically deformed in the longitudinal direction and easily stretched in the longitudinal direction, so that they can be easily fitted.
The pieces of the metal chain before being fitted are in a positional relationship in which adjacent pieces intersect, as shown in Figure 4 (E), so as shown in Figure 4 (F), one of the metal chain pieces is in the girdle of jewelry a, one of which is indicated by a broken line. Alternately fit one side into the bottom side of the girdle, and the other side into the top side of the girdle.
After being fitted, the stone frame 1 is elastically restored and shortened to fix the jewel a and firmly hold the jewel a.

[Method of using the stone frame of the present invention (stone frame fitted with a jewel) as an accessory 1]
FIG. 5A is a front view of an example of a necklace in which the stone frame 1 into which the jewel a is set is used. A necklace ring f is attached to one of the pieces of the main stone frame 1, and a necklace chain g or the like is attached to the necklace ring f.

Attach the left and right ends of the bracelet chain j, etc. to the
The necklace ring f, the bracelet ring 1 (h), and the bracelet ring 2 (i) may have the same shape, or they may be used once attached.
FIG. 5C is a side view of an example in which the stone frame 1 into which the jewel a is set is used as a ring. An auxiliary metal chain k for a ring is attached to four pieces of the main stone frame 1 to surround the pavilion part of a jewel a, and a ring m is further attached to the piece of the auxiliary metal chain k for a ring corresponding to the lowest part of the jewel a.
The auxiliary metal chain k for the ring is a metal chain different from the metal chain of the main stone frame 1, and may have any shape and size as long as it can surround the jewelry a. In addition, in (C) of Fig. 5, the metal chain of the main stone frame 1 is shown with a different size of the pieces, but the size and shape of the pieces are the same as those of the main stone frame 1. It's okay.

[About the effect of the stone frame]

The first embodiment has the effect that it is possible to supply a stone frame with a high design quality by improving the design of the metal chain itself, and the shape of the pieces and their combinations.
The reason is as follows.
In other words, first of all, it can be said that the use of metal chains itself enhances the design of the stone frame, and furthermore, since the metal chain pieces are not limited in material other than being made of metal, the design can be improved depending on the material. This is because it is possible to enhance the design quality (for example, by using gold, platinum, gold alloy, gold plating, etc. as the material) or by applying a vivid pattern or color scheme.
It is also necessary that each piece of the main stone frame has a substantially circular or oval shape, and that each piece has the same length in the longitudinal direction. Conversely, it is possible for each frame to be all substantially circular, all to be substantially elliptical in the same shape, or to be a combination of substantially circular and substantially elliptical shapes that are the same or different in shape. This is because the design of the shape of the top can be improved.
In addition, in the above usage method 2 (paragraph 0025), the main stone frame piece and the series of metal chain pieces are the same in shape, size, and material, providing a unified design for the entire accessory. This is because it is possible to do so.

In the second method of using the stone frame (stone frame in which a jewel is set) of the first embodiment as an accessory, the pieces of the real stone frame and the series of metal chain pieces are different in shape, size, and material. Since the pieces are the same and the same pieces can be used, the number of parts can be reduced when constructing the entire accessory.

The first embodiment has the effect that it is possible to provide a stone frame that can sufficiently secure incident light to the jewel pavilion.
The light that enters the jewel pavilion bounces off the crown, which has the effect of making the jewel shine even more as the light radiates from the crown, as well as the effect of dispersing the light and emitting rainbow-colored light.
The reason why sufficient light can be ensured to enter the pavilion is as follows.
First, the main stone frame has a structure made of metal chains, and since it functions as a stone frame by holding only the girdle part with the chain, the pavilion part of the jewel is not shielded.
The top of the jewel pavilion will also be covered with the metal chain. However, the metal chain consists of substantially circular or substantially elliptical pieces, and the ratio of the open area to the covered area is large. Therefore, sufficient sunlight can be obtained even from the covered parts. This point is the same even when the accessory is a ring and the pavilion is surrounded by a metal chain as in the usage method 1 (paragraph 0024) above.

According to the first embodiment, it is possible to easily hold the jewel while ensuring sufficient jewel retention force. In addition, it is possible to provide a stone frame that does not require any special processing during work to hold the jewel and does not damage the jewel during the work.
These reasons are shown below.
Since the stone frame has a metal chain structure in which the pieces are approximately circular or oval, each piece tends to become more elliptical when pulled in the longitudinal direction, and the diameter of the stone frame as a whole tends to expand due to elastic deformation. It has the following characteristics.
Therefore, when fitting a gemstone into the stone frame, it can be easily fitted by stretching the gemstone in the longitudinal direction (elastically deforming it) by taking advantage of the property that it is easily elastically deformed.
Furthermore, after being fitted, the stone frame elastically returns to its original length and becomes shorter, sufficiently fixing the jewel and ensuring sufficient jewel holding power.
Furthermore, since the stone frame has such a structure, no special processing is required when fitting the stone, and the jewel will not be damaged during the fitting process.

The first embodiment has the advantage that it is possible to provide a method for manufacturing a stone frame in which the actual stone frame can be manufactured easily and there is no risk of damaging the jewel during manufacturing.
The reason why it is easy to manufacture is as follows.
This is because each of the steps 1 to 4 of manufacturing method 1 or steps 1 to 5 of manufacturing method 2 are only relatively easy steps.
In addition, manufacturing method 2 in particular is easier to manufacture. That is, when setting the length of a series of metal chains in step 1 of the same method, the diameter can be adjusted using plastic deformation in step 5, so there is no need to perform exact calculations and settings.
The reason why there is no risk of damaging the jewelry during manufacturing is that when manufacturing the stone frame, it is only necessary to measure the size and shape of the jewelry, and the manufacturing does not involve using the jewelry itself.

The first embodiment has the advantage that it is possible to provide a stone frame that can be easily processed into jewelry. Furthermore, processing for making such jewelry has the effect that it is easy to process for conversion to other jewelry and does not damage the jewelry during conversion.
The reason is as follows.
In the above-mentioned usage method 1 (paragraph 0024), when the accessory is a necklace, the necklace ring is simply attached to one place on the top. If the accessory is a bracelet, simply attach the bracelet rings to two opposing pieces. This is because when the accessory is a ring, the auxiliary metal chain for the ring is simply attached to four locations on the top.
Moreover, in the above-mentioned method of use 2 (paragraph 0025), a series of metal chains are simply attached to two places on the pieces of the stone frame.
In addition, since these can be processed with the gemstone still fitted into the stone frame, it is easy to convert it into other jewelry (or replace the ring itself), and when converting, etc., the ring itself can be processed. This is because there is almost no possibility of injury.

As described above, the stone frame according to the present invention is useful in that it can provide a stone frame that secures sufficient incident light, ensures sufficient jewel-holding power, and is easy to work with to hold jewels. Further, the method for manufacturing a stone frame according to the present invention is useful in that it can provide a method for manufacturing a stone frame that is easy to manufacture and does not cause damage to jewelry during manufacturing.
