Description

Detailed Description of the Invention

The present invention relates to a transparent jewelry observing instrument that emits internally reflected light such as diamond.

At present, it is common knowledge in the world that the value standard of jewelry is evaluated by four elements of carat, color, clarity and cut. One of them, the cut, is the only element that humans need to deal with, and it is regarded as important because it greatly affects the beauty and value of jewelry.

For this reason, it is necessary to visually distinguish the state of cut polishing applied to individual gemstones and require a reliable evaluation, but it is possible for a skilled person with a high level of skill to do it with only a magnifying glass. It is impossible for general consumers, and it is difficult to make a reliable evaluation even for highly skilled workers, especially in round brilliant cuts where strict standards and fine grading are performed.

As an instrument that can be easily discerned by anyone, regardless of skilled traders or general consumers, the individual state of gemstones that have been cut and polished, mainly round brilliant cuts. No. 103268 and JP-A-8-271434. The former has a structure in which the upper cylindrical portion is made of a translucent material and the lower cylindrical body is made of an opaque material, and the light source for irradiating jewelry to be observed is a first light source from the upper translucent cylindrical body. The latter has a disk-shaped reflector on the top, is equipped with a colored translucent light-collecting tube, and the first light source irradiated to the jewelry that is the object to be observed is obtained from the reflector on the top. ing. Both the former and the latter are structured to obtain a second light source of a different color from the first light source from the lower cylindrical body, and the jewelry reacts to these two different lights and appears as a reflected image, so that the reflected image By observing the shape of the pattern, regularity, symmetry, brightness, etc., it is said that the quality of the cut accuracy, the degree of brightness, and the presence or absence of value can be easily evaluated.

However, in conventional techniques such as the instruments shown in the above Japanese Patent Publication No. 6-103268 and the above-mentioned Japanese Patent Application Laid-Open No. 8-271434, the light irradiated on the jewelry of the object to be observed is transmitted or reflected by the translucent material. Because it is the reflected light of the plate, it is easily affected by the color and brightness of the member used as the light source, and therefore it will also affect the jewelry. Observations drawn out to the maximum are inadequate.

In recent years, with the improvement of cut polishing technology, various ingenuity has been applied to the shape of gemstones, the number of cut surfaces, and the angle of the cut surface in order to further differentiate them, and how the reflected image looks when observed with an instrument. However, since the conventional technique mainly devised the observation of round brilliant cuts, the incident angles of the first light source and the second light source are limited. It is difficult to visually confirm the minute reflected light and the impressive reflected image.

The observation instrument of the present invention efficiently irradiates the jewelry that is the object to be observed with the wavelength of light obtained from the environment of the place without being affected by the brightness and color tone of the translucent member and the reflector member, Observe the details of individual gemstones with traditional cuts, such as round brilliant cuts, and new cuts with an emphasis on the appearance of reflection patterns that have increased in recent years. The purpose is to accurately capture characteristic and fine reflected images.

As a means for effectively irradiating the jewelry that is the object to be observed with the highest quality light, a declination surface is formed on the cylindrical body using a transparent member, and the gemstone is irradiated with the light generated on the declination surface. The obtained light source.

In addition, a cylindrical body formed of a colored member that can serve as a second light source at the bottom of the transparent cylindrical body is configured to be detachable so as to correspond to observation of the reflective ability of various cut-shaped jewelry that has been increasing in recent years. The contact point between the light from the declination surface and the light of the colored cylinder is variable.

Embodiment

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments for carrying out the invention will be described with reference to the accompanying drawings.
FIG. 1 is a front perspective view of a jewelry observation instrument according to the present invention formed integrally using a transparent member. FIG. 4 is a sectional view thereof. Jewelry that has an observation hole 13 in the upper part of the transparent cylindrical body 1 and has a declination surface 2 having an angle for condensing ambient light inside, and is born as a first light source. Irradiate. The magnifying glass 4 is detachably set by the magnifying glass support part 3 having a convex part, and the magnifying glass is attached at the time of magnifying observation, and the magnifying glass 4 can be removed at the time of magnification observation and photography. The colored tube 5 is attached as a second light source in the lower part of the cylinder so as to be replaceable, and has a color tone or brightness different from that of the first light source generated on the cylindrical upper deflection surface 2. Since the colored tube 5 can be seen through from the outside, the advertisement paper 6 is inserted between the tube and the colored tube 5. A holding plate 7 having a hole diameter smaller than the inner diameter of the lower part of the cylindrical body is detachably attached so that the colored cylinder 5 and the advertisement paper 6 do not easily fall off.

Although it comprised as mentioned above in embodiment, about the transparent cylinder 1, the cylinder upper part used as a 1st light source and the cylinder lower part used as a 2nd light source are isolate-molded like FIG.5 and FIG.6. It is also possible.

The second light source can be colored by the colored cylinder 5, but when separated and formed, the same effect can be obtained even if it is formed of a colored member in the lower cylinder. In this case, the upper cylinder and the lower cylinder may be combined, and it is also effective to be detachable so that the second light source can be replaced with a lower cylinder of a different size.

Further, the upper cylindrical deflection surface 2 is not limited in shape as long as it has an angle capable of guiding light into the cylindrical body, and may be wavy, for example, using a popular character or the like, The effect may be obtained.

In addition, the colored tube 5 is not limited to one color, and if it is made using paper or the like, it is possible to easily arrange a plurality of colors horizontally or vertically. The variety of light sources is effective for visually observing the incidence and reflection of light and the trajectory of jewelry. Further, when printing, printing, coloring, or the like is performed on the outer surface of the colored tube 5 by any method, the same effect as that of the advertisement paper 6 can be obtained, so the advertisement paper 6 may be omitted. Similarly, the advertisement paper 6 may be omitted even when printing or printing and coloring are not required.

Further, the advertisement paper 6 can be replaced in various ways such as a commemorative photo and a message according to the customer's request.

Further, the colored tube 5 and the pressing plate 7 may be integrally formed using an acrylic material or the like. Further, the pressing plate 7 may not have the same effect if a small convex portion is provided at the lower part of the cylinder, and may be omitted even when the colored cylinder 5 and the advertising paper 6 do not need to be fixed. .

The invention's effect

The present invention is configured as described above, and the following effects are achieved according to the present invention.
By obtaining the first light source that irradiates the jewelry that is the object to be observed placed at the bottom of the cylindrical body from the declination surface arranged on the transparent cylindrical body, extremely high-quality light can be obtained. It is possible to observe even a minute difference in cut surface that cannot be observed by the method obtained from the member or the method obtained from the reflection root.

Furthermore, it becomes possible to clearly observe fine objects such as impressive reflected images appearing from complicated cut surfaces of new-shaped jewelry that have been rapidly increasing in recent years.

Furthermore, since the incident angle of the second light source can be varied, both the conventional cut-shaped jewelry and the new-shaped jewelry can be observed.

In addition, for the type that can insert or replace the colored tube 5 or the like as the second light source, it becomes possible to integrally mold the upper and lower cylinders with a transparent member, thereby improving productivity and significantly reducing production costs. Therefore, it can be widely spread as a very inexpensive product.

Furthermore, since the colored cylinder 5 as the second light source can be seen through from the outside, the lower cylinder when integrally formed using a transparent member can be used to display advertising characters or the like on the outside visible portion that is the back surface of the colored cylinder 5. Since it is possible to print, or an advertisement printed matter can be inserted between the cylinder and the colored cylinder 5, it can be used as an advertisement medium rich in originality.

In addition, it is possible to insert a commemorative photo, original message, illustration, picture, etc. according to the consumer's wishes, so that it can also serve as an ornament in addition to serving as an observation instrument.
