DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnifying tool for gemstones having a cut surface such as cut diamonds, and more specifically, to the transmission and reflection of light beams by each cut surface of jewels such as cut diamonds. The present invention relates to a gemstone magnifying device capable of enlarging the appearance of an image or gem.

[0002]

2. Description of the Related Art Conventionally, as a device for magnifying a jewel having a cut surface such as a cut diamond or the like to check the condition of the jewel, a gemstone is irradiated with white light using a dark field illumination device. An apparatus has been used in which a cut surface of a jewel by the irradiated light beam is visually recognized with a magnifying endoscope or the like. Alternatively, a supporting means having a cut surface such as a cut diamond as disclosed in Japanese Patent Application Laid-Open No. 186171/1994, and an irradiating means for irradiating a gem supported by the supporting means with a plurality of divided light beams of different colors There is a magnifying device for a jewel having a cut surface provided with a magnifying device for magnifying a gem irradiated by the irradiating device. Thus, the reflected light of different colors from each cut surface can be magnified by the irradiated light beam, and the cut state of the jewel can be determined. Further, it has been possible to display the magnified state as an image on a display or to display the state on a medium such as paper with a printer or the like.

Therefore, in the gem magnifying device having such a cut surface, the quality of the gem, such as impurities and transparency in the gem, and the quality of the cut, are magnified using light rays. This made it easy and reliable to judge the jewelry and made it possible to show the condition of the jewelry to the buyer. In particular, a magnifying device for gemstones disclosed in Japanese Patent Application Laid-Open No. 186171/1994 not only allows the brightness of a white light but also the brightness of a cut surface due to light rays to be magnified with colors, thereby improving the certainty of gemstone identification. In particular, there is an extremely great advantage that the measure symmetry in the cut evaluation can be easily discriminated even by an unskilled person.

[0004]

However, these magnifying devices for gemstones each have a complicated mechanism and require expensive devices. Especially, when specialized in jewelry appraisal or at a store. Although it is possible, it is impossible for a general consumer who is not an expert to prepare such a device by himself. In particular, users of jewelry, who are consumers, can only grasp the status of jewelry at the level of appraisal and explanation at the store. It could not be used. For example, a skilled person can magnify the gem with a magnifier such as a loupe to see the state of the jewelry, but a non-expert ordinary user can see the state of the jewel even with a magnifying glass The quality of the cut surface could not be determined, and it was difficult to visually and visually grasp the beauty of the cut surface.

When viewed with a magnifying glass, the gem is usually in a state of receiving the entire beam of light, and the appearance of the gem is merely enlarged. I couldn't do that.
That is, in such a state, depending on the condition of the light beam, it is extremely difficult to form an image of the light beam due to the transmission and reflection of the light beam, and it is impossible to visually recognize the quality of the cut state of the jewel by this image. Alternatively, it is possible to focus the light beam in the direction of the jewel using a reflector or the like, illuminate the jewel brightly, and visually recognize it with a magnifying glass or other loupe. However, the entire jewel is brightly illuminated and transmitted through the jewel. As for the image of the light beam generated by the reflection on the cut surface, the entire image generated on the cut surface of the entire jewel is visible, and it is not possible to express only a specific image clearly.

In particular, when a specific image is to be displayed, and in order to make the image easy to see, when a transparent light beam is used, the amount of the light beam generated in the image also passes through the jewel. At the same time, the transparent light is reflected and the image emerges in a shining state, it is difficult to see when viewing it, and the boundary line of the image is blurred, and the image is not clearly displayed there were. Accordingly, the image of the light beam or the appearance of the jewel by the transmitted light and the reflected light of the light beam for each cut surface of the jewel can be clearly magnified so that the user who is the demander can at least judge the quality of the jewel. There has been a demand for visual aids and that this device be extremely inexpensive and easy to use. In addition, consumers who purchase and use gems can easily determine the quality of gems and understand the beauty of gems by easily enlarging the inherent beauty of the jewel itself and its cuts. It can be purchased and can contribute to expanding demand.

[0007]

SUMMARY OF THE INVENTION Accordingly, it is possible to solve the above-mentioned problems and to enable a consumer who purchases and uses jewelry to easily determine and understand the goodness of jewelry without using complicated and expensive equipment. A substantially hemispherical shaped lens according to the invention according to claim 1, which is an inexpensive and easily magnifying visual tool that can easily and easily magnify the image of a light beam or the appearance of a gem by the reflection and transmission of a light beam for each cut surface of a jewel. A jewel magnifying tool having a hole in the center of the main body and having a magnifying lens inside the substantially hemispherical main body, and magnifying the jewel by looking through the hole. An object of the present invention is to provide a translucent gem magnifying visual tool, which can be achieved by the invention. Alternatively, a translucent member is disposed on the inner surface and / or the outer surface of the main body as in the invention according to claim 2, and the light transmitted through the main body is converted into a translucent light to irradiate the jewel with an enlarged view of the jewel. The problem can be solved in the same manner depending on the tool.

In this case, the problem can also be solved by a gem magnifying tool in which a cylindrical body is connected in the direction of the opening of the main body. Further, the cylindrical body may be translucent as described in claim 4, or may be transparent as in the invention described in claim 5. In the case of translucent, for example, it may be cloudy as described in claim 6, or may be translucent having a color as described in claim 7. In addition, a member having a color transmitting light rays is provided on the outer peripheral surface and / or the inner peripheral surface of the cylindrical body as described in claim 8, or the cylindrical body transmits light. Even if it is made of a member that does not transmit light, or a member that does not transmit light is provided on the outer peripheral surface and / or the inner peripheral surface of the cylindrical body and blocks light transmitted through the cylindrical body from the outside, the image of the light beam is more improved. Can be raised.

Alternatively, the contrast between the image of the light beam and the other parts can be clearly determined even if at least one of the hue, the saturation, and the brightness differs between the main body and the cylindrical body. It is possible to make the image stand out more. Further, the magnifying lens may be provided inside the cylinder instead of inside the main body as described in claim 11. In addition, as for the cylindrical body, as shown in claim 12, the cylindrical body is not a cylindrical shape, but is formed of a rectangular shaped member having a cavity with a hollow or more than a triangular cross section and located between the main body and the jewel to be visually recognized. Is also good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing an embodiment of the basic structure of a magnifying gaze tool for jewels according to the present invention. A hole 2 is formed in the center of a substantially hemispherical main body 1 made of a translucent member.
And a magnifying lens 3 inside the body 1 in the end direction. The gem 7 can be magnified and viewed through the magnifying lens 3 by looking into the hole 2 of the magnifying gaze tool having such a configuration. Therefore, it can be manufactured very simply and inexpensively. In this case, since the main body 1 is formed of a translucent member and has a substantially hemispherical shape, natural light such as the sun and light from a light source such as a light outside the magnifying glass are translucent. Color and irradiate jewelry 7,
Irradiation is performed by changing light from a certain direction to light emitted from other places.

Further, light passing through the substantially hemispherical main body 1 composed of a translucent member is transmitted through the translucent member, and is changed from translucent light to so-called translucent light. It will illuminate the jewels 7 and the like. Therefore, the light emitted from the upper direction having the hole 2 passes through the main body 1 made of a translucent member, and the light changed to be translucent from the upper direction of the jewel 7 is incident, and the light is emitted from the peripheral portion. The light is emitted as transparent light in the jewel 7 direction. This means that when the jewel 7 is viewed from the top,
Light from an acute angle direction, which is an upper direction not so different from the perpendicular to the jewel 7, is irradiated with translucent light, and light from an obtuse angle with respect to the perpendicular is irradiated with transparent light,
Irradiated on the jewel 7, a contrast between transparent and translucent light is produced. Among these light rays, light from a certain direction, for example, for example, in a brilliant-cut diamond having a good cut state, particularly a diamond having a good symmetry, expresses an image of a specific light ray.

That is, when viewed in a table-up state, a light ray that has entered at an acute angle with respect to the perpendicular of the jewel 7 is reflected twice inside the jewel 7 and is emitted from the table direction. On the other hand, most of the light rays that enter at an obtuse angle to the perpendicular will be emitted from the side and the like without such reflection, and are hardly visible as light when viewed from above, that is, from the perpendicular direction. Becomes Therefore, when visually recognized using the magnifying visual device according to the present invention, light incident from the perpendicular direction, which is the upper direction, is reflected, and a light beam is emitted in the upward direction. It will be visible. In this case, the magnifying visual tool irradiates the light from a specific direction among the light from the upper direction as translucent light in the jewel 7 direction, reflects the light in the jewel 7, and emits the light in the hole 2 direction. By using translucent light that is not transparent light to create the image of the light beam, the image of the light beam will be displayed not only as a transparent shine but also as a beautiful image that is easy to see in a translucent state. By keeping or blocking the light ray of the light, the light ray from the other direction becomes transparent light or shadow, etc., and it is possible to give contrast to the image of the light ray made from translucent light and other parts, The difference between the two can be clarified.

In particular, of the light rays incident from the center of the table, particularly those entering at about 9.35 degrees, are reflected twice in the jewel 7 and emitted from the end of the table in the direction of the hole 2.
Similarly, of the light rays entering from the cut end of the table, the light rays entering at about 9.35 degrees are also reflected twice in the jewel 7, and the end of the jewel 7 when viewed from above, that is, the oblique side that follows the table, that is, the bezel. It is injected in the direction of the hole 2 from the end portion of the shaft. At the same time, in the light beam incident from the oblique side portion following the table, that is, from the table direction of the bezel facet, particularly about 12.07
The light rays that have entered at a degree are reflected twice in the jewel 7 and emitted from the center of the table. Similarly, in the light beam incident from the other end of the bezel facet, about 12.0
The light ray that has entered at about 7 degrees is reflected twice inside the jewel 7 and is emitted from the end portion of the table.

The images resulting from the reflection of these light rays are represented in the jewel 7 as arrow-shaped images. The light rays penetrating at about 9.35 degrees out of the incident light rays reveal the arrowhead portions 80 of the arrow feathers.
The light ray that has entered at about 2.07 degrees is the arrowhead portion 81 of the arrow feather.
The image of is expressed. Accordingly, by making the light beam in the range of about 9.35 ° to about 12.07 ° from the perpendicular of the jewel 7 translucent, the image of the light beam appearing in the jewel 7 can be clearly raised. Things. The image is clearly displayed by using other light beams, for example, transparent light or colored light. Therefore, by making the main body located at the peripheral portion of the hole 2 for viewing the jewel semi-transparent as described above, the brilliant-cut diamond has a table surface 71 cut into an octagonal shape. The image of the arrow-shaped light beam of the book is clearly visible.

The diamond is clearly cut so that the image of the eight arrow-shaped light beams can be clearly displayed, and the quality of the cut can be visually recognized by the image of the light beam. It is possible to visually recognize a beautiful image of light rays based on the quality of the diamond based on the quality of the diamond, and to recognize the value of the diamond for the consumer himself, and the beauty can lead to a new purchase. Similarly, in a state where the brilliant cut diamond is set down the table, that is, the culet is directed downward, the eight heart shapes 90 can be clearly recognized by light from above. The substantially hemispherical main body 1 does not necessarily have to be a half circle of a perfect circular sphere, but may be a half halves of a substantially spherical shape, or one third or two thirds. The shape may be one, and the shape is not limited to a perfect spherical shape, and the shape of the radius may be small or large.

Therefore, even if it is an elliptical shape, a shape having a substantially uneven shape with different round angles, or a polygonal shape composed of a plurality of straight lines having different cross-sectional viewing angles, a pyramid shape It may be. At least a portion of the main body 1 around the hole 2 that transmits light emitted in the jewel 7 direction from above may be used. For example, about 9.35 degrees with respect to a line connecting the jewel and the central axis of the hole. What is necessary is just to have a translucent main body in the range of about 12.07 degrees. A ray having this angle constitutes an arrow-shaped image in the rays illuminating the jewel, and this ray is transmitted through the translucent main body so that it can be contrasted with other rays, and has an arrow-shaped shape. The image can be raised. Therefore, in the present specification, all these shapes are included and displayed as a substantially hemispherical shape.

The translucent material may be, for example, an opaque translucent material or a milky translucent material. The translucent material may be formed by adding a certain color or dullness to an ordinary transparent light beam. What is necessary is just to raise a light beam. For example, when the opaque translucent main body 1 is used, the arrow-shaped image generated in the jewel can be visually recognized as floating in white, and a clear contrast different from reflection by a transparent light beam can be generated. When a milky white translucent main body 1 is used, the arrow-shaped image is raised as milky white. In addition, the translucent material may be colored and have a hue such as red or blue. That is, a transparent member having a hue, for example, a transparent member having a color is not completely transparent but also corresponds to the translucent in the present invention, and even if such a member is used, a light beam transmitted through the main body 1 is a hue. That is, a colored light beam having
The reflected light can produce an arrow-shaped image with the color.

For example, the main body may be composed of a member having a color of an upper hue such as cloudy. This also allows the image to be clearly displayed as a color image. Also, for example, a film having a color may be attached to or attached to the inner surface or the outer surface of the upper body using a translucent member such as cloudiness, and the color may be applied to the light beam by another member instead of the member itself. Good. In addition, it is also possible to use a translucent separate member for the transparent main body 1 to transmit light rays from above in a semi-transparent manner and change them into translucent light rays. It suffices if at least the light from the upper direction is changed to a translucent light and can be applied to the jewel 7 or the like.
By making the main body 1 itself or another member translucent in this way, the light emitted from above with respect to the normal of the jewel in the emitted light is transmitted through the main body to give a contrast, and The image of the light beam generated in the inside 7 can be raised.

The main body 1 as described above is not limited to, for example, one made of a synthetic resin, but may be another member, as long as it is formed of at least a moldable material. Next, the magnifying lens 3 provided in the main body 1 may be any as long as the jewel 7 can be viewed in an enlarged manner.
Even if it is fitted in the inside of the main body 1, it is arranged near the hole 2, it is arranged in the hole 2 itself, or the end of the opening of the substantially hemispherical main body 1. It may be provided. Further, the lens 3 may be provided by providing a flange at the opening end of the substantially hemispherical main body 1. Alternatively, the lens 3 may be provided with an arm or a connecting portion from the opening of the main body 1 so as to be able to hold the lens 3. A lens 3 capable of enlarging the jewel 7 at least on the main body 1
It is sufficient if it has. Next, the size of the hole 2 in the center portion of the substantially hemispherical main body 1 may be any size, and the size may be determined as needed.

The shape of the hole 2 is not limited to the circular hole 2 but may be an elliptical shape, a square shape, or an arbitrary shape. A hole 2 in which at least the jewel 7 can be viewed and an image of a light beam generated in the jewel 7 can be seen.
If there is. When the jewel 7 is visually recognized, for example, a ray in the range of about 9.35 degrees to about 12.07 degrees from the perpendicular of the jewel is reflected twice in the jewel and emitted in the direction of the hole 2 which is the perpendicular direction. What is necessary is just to have the hole 2 so that the light beam for visually recognizing the image generated in the jewel 7 can see the light beam emitted in the direction of the hole 2. still,
Regarding the radial length of the hole 2, that is, the size of the hole 2,
As described above, it is only necessary to have a size that allows the image to be visually recognized. However, by slightly moving the magnifying eye closer to or away from the jewel 7, it is possible to slightly adjust the magnification depending on the use state. May be any size or shape. It is most desirable that at least the outer frame line forming the hole 2 is located at a position regulating the perpendicular line connecting the jewel 7 and the central axis of the hole 2 to a line of about 9.35 degrees.
Is most desirably located from a line at about 9.35 degrees. That is, since the outer frame forming the hole 2 is located at this position, the light beam for forming the image can be transmitted through the main body 1 and the jewel 7 can be visually recognized from the hole 2 in the widest range.

FIG. 2 is a sectional view of the main body 1 of FIG.
As shown in the figure, a lens 3 is provided in a substantially hemispherical main body 1. Arrows 10 show an example of incident and exit angles of light rays, which are transmitted through the translucent portion of the main body 1 and incident at an angle of about 9.35 degrees with respect to a perpendicular to the table surface 71 of the brilliant diamond. This shows an irradiated light beam, which is reflected twice by the cut surface and emitted toward the hole 2.
An arrow 11 similarly indicates a light beam which is transmitted through the translucent portion of the main body 1 and is incident at an incident angle of about 12.07 degrees from the oblique side following the diamond table, that is, from the table direction of the bezel facet, The light is reflected twice in the jewel 7 and emitted from the center of the table. In this way, these light rays pass through the main body 1 to change the light rays from transparent to translucent, and the light rays generated by reflecting the light rays through the jewel 7 on the cut surface are translucent. The image is clearly and clearly expressed, and the image of the light beam expressed on the jewel 7 can be seen from the hole 2.

FIG. 3 is a sectional view showing another embodiment of the gem magnifying gaze according to the present invention. A hemispherical main body 1 having a hole 2 has a cylindrical body 4 in the opening direction. The inside of the cylindrical body 4 is hollow, and the other end thereof is open, forming an opening of the cylindrical body 4. In this case, the lens 3 may be provided inside the main body 1 as shown in FIGS. 1 and 2, or may be provided inside the cylindrical body 4. FIG. 3 shows a state where the lens 3 is disposed in the cylindrical body 4. Therefore, when the jewel 7 such as diamond is positioned in the direction of the opening of the cylindrical body 4 and the inside is viewed through the hole 2, the jewel 7 can be enlarged and viewed by the lens 3. in this case,
The substantially hemispherical main body 1 is made of a translucent member, and light rays from the upper direction of natural light such as the sun and light from a light source such as a light outside the magnifying glass pass through the translucent member. This gives a contrast different from that of a so-called transparent light beam that is applied to the jewel from other places, and illuminates the jewel 7, etc., so that the image of the light beam can be clearly displayed, and the reflection of the jewel in this portion Light and contrast can be added.

In particular, the cylinder 4 may be a transparent member or a member that does not transmit light. For example, when a transparent member is used for the cylinder 4, the light beam transmitted through the main body 1 is a translucent light beam, and the light beam transmitted through the cylinder 4 is a transparent light beam. Not only can the light beam produced become a translucent light beam, and the image appearing in the jewel 7 can be clearly displayed, but also the light beam producing the image appearing in the jewel 7 can be contrasted with other light beams. Can be attached, and an image of an extremely clear light beam can be displayed. When a member that does not transmit light is used for the cylinder 4, the light transmitted through the main body 1 becomes a translucent light, and the light is blocked by the cylinder 4, so that an image appearing in the jewel 7 is not reflected. Not only can the light beam to be produced be a translucent light beam, and the image appearing in the jewel 7 can be expressed beautifully, but by blocking the light beam from the side, the parts other than the image become shadows, The image of the light beam can be made more prominent.

In addition, for example, the cylinder 4 may be formed using a translucent member. In this case, the light beam transmitted through the cylindrical body 4 is also a translucent light beam, and becomes a translucent light beam like the light beam transmitted through the main body 1. Although there is no contrast between the two, an image expressed in the jewel 7 is formed. Since the light beam transmitted through the main body 1 is translucent, the image of the light beam due to the reflection of the cut surface of a transparent jewel or the like is translucent, and is different from an image generated simply by applying transparent light, for example, cloudy. The image can be created in such a state, and the visibility of the light beam image becomes extremely high. Also, the light rays reflected from the side part in the direction of the hole 2 are only a part of the light rays, and the image of the light rays is clearly displayed. Therefore, in the case of a brilliant-cut diamond with good symmetry, eight arrow-shaped images 80 and 81 can be clearly seen in the table-up state, and eight heart-shaped images 90 in the table-down state. It is clearly visible.

It should be noted that the cylindrical body 4 of the magnifying gem of the jewel shown in this figure does not necessarily have to be cylindrical. That is, for example, it may have a prismatic shape or an arbitrary shape. It is made of an angular member having at least a hollow and having a corner having a cross section of not less than a triangle, and is located between the main body 1 and the jewel 7 to be visually recognized. It is only necessary to be visible. The magnifying lens 3 itself may be provided in the main body 1 or may be provided in the cylinder 4. The provision of the cylinder 4 also has the additional effect of allowing a certain distance between the hole 2 and the lens 3 and the jewel 7 to be viewed. Therefore, the length of the cylindrical body 4 in the longitudinal direction may be any length. Next, the cylindrical body 4 may be transparent or translucent as described above, or may be made of a member that does not transmit light. May be used. Cylinder 4
For example, by adding a color to the image, a portion other than the image of the light beam can be colored with a color, and conversely, the image of the light beam can be raised, so that the image of the light beam can be visually and clearly magnified.

Further, not only the cylinder 4 but also the substantially hemispherical main body 1 may be made of a cloudy one or a translucent one with a color. Accordingly, the image of the light beam can be similarly raised, the portion other than the image of the light beam can be expressed dimly with color, and the image of the light beam can be clearly lifted. Alternatively, for example, the hue of the main body 1 and the hue of the cylindrical body 4 may be different from each other to give a hue contrast, so that, for example, the image of the light beam becomes one color, while the other part is formed of another color. Can be projected with. Accordingly, only the substantially hemispherical main body 1 or the cylindrical body 4 may be colored, or both may be colored, or the main body 1 and the cylindrical body 4 may have hue, saturation, and lightness. Even if any one or more of them is different, it is possible to sufficiently provide contrast. FIG. 4 shows an image 8 of a so-called arrow-shaped light beam.
0 and 81, an image 80 of an arrowhead-shaped arrowhead is symmetrically displayed on the brilliant cut table surface.
On the side slope of the cut surface, images 81 of eight arrowhead parts are displayed symmetrically, respectively, corresponding to the image 80 of the arrowhead part. FIG. 5 clearly shows the images displayed when the table is down, that is, when the culet is up, and a total of eight heart-shaped images 90 are displayed symmetrically.

As described above, the use of the magnifying gemstone of the present invention makes it possible to very easily magnify the image of the light beam due to the transmitted light for each cut surface of the gemstone 7. FIG. 6 shows an example of an enlarged gem of a gem according to the present invention, in which a film 5 having a color that allows light to pass therethrough is attached to the inside of the cylinder 4, and the light transmitted through the cylinder 4. FIG. 9 is a diagram showing a state in which the image of the light beam due to the reflection and transmission of the light beam for each cut surface of the jewel 7 or the appearance state of the jewel is made visually recognizable with a color contrast. By transmitting the light from the upper direction having the hole 2 of the main body 1 through the main body and making the light translucent, the images 80, 81, and 90 are formed by arrow-shaped or heart-shaped light rays. The portion has a different color due to the film 5 having a color that allows light to pass therethrough, and can be very clearly enlarged and viewed.

By arranging the film 5 in this manner, a color can be added. On the contrary, the film 5 can be easily replaced by a film 5 having a desired color for a consumer. Color can be used. In this figure, a film was used to add color, but the invention is not limited to this, and any other member that can transmit light and that can add a certain color or saturation can be used. For example, even if a translucent member is arranged in a transparent cylinder to make light rays passing through the cylinder translucent,
In addition, for example, a thick paper, film, or the like that blocks light rays may be provided in the cylindrical body 4 so as to block light rays from side portions and take in only light rays from above. As described above, particularly in diamonds having cuts, the cut state can be extremely visually recognized, but for example, other jewels can be magnified, and the light from the upper part and the light from other parts can be seen. The jewels can be magnified with contrast, the quality of jewelry can be visually recognized, and users who are consumers can recognize the original beauty of the jewelry.
