The technical field

The present invention relates to a device for visual observation of the labels on the verge of a precious stone, use an external light source. The invention relates in particular to the case for jewelry, which is used to store precious stones, particularly diamonds, or jewelry containing precious stones, in particular rings or earrings.

Prior art

Known cases for jewelry, consisting of a substrate serving as a support for precious stones or articles, and cover, which is rotated with respect to the substrate so that when the lid is closed, a precious stone or the product is inside a protective case, usually opaque to protect the precious stone or products from damage, and to a certain extent, to protect the jewelry or precious stone dust, and also to provide a larger volume, therefore, especially for precious stones, the topic is no longer relevant.

In recent years, some manufacturers of diamond introduced the practice of placing a label on the setting of precious stones and, more recently, on the verge of precious stones. The label may be a label containing any information, or stamp, such as an alphanumeric label, showing the origin is their gemstone or serial number, and/or may be a logo or trademark and/or mark indicating quality and authenticity. In accordance with modern technologies label is created on the edge by removing microscopic amounts of material precious stone, which can be considered as the application of the notches. Application technology notches are described, for example, in the United Kingdom patent 2325392 and publication WO 97/03846. The advantage of placing the label on the edge is that the face is not to be hidden when mounted gemstone. The label may be small enough in order to avoid reducing the value of a precious stone, usually it is invisible to the naked eye. However, the presence of labels on the verge of a gemstone is a valuable indicator, for example, that precious stone is synthetic and has not been treated to improve its color.

There are several ways of checking labels on the verge of a precious stone, but, in addition to using a simple magnifying glass magnifier for recognition labels or magnifying tweezers, they all require relatively bulky equipment, as well as, for example, removal of a precious stone from its case. There is a need to create a simple and convenient way to check the label. It is preferable to develop a method that does not require removal of dragon the frame of the stone out of the case and at the same time makes it easy to remove the gem from its case when it is required. The present invention is to eliminate at least one of the disadvantages of the prior art or the creation of a suitable alternative.

Any citation of prior art in the description is the recognition that the prior art is widely known or forms part of common knowledge in this field.

Disclosure of inventions

In the invention, an apparatus and method for monitoring. The invention can be created inexpensive device that uses an external light source, such as ordinary room light, or the top of the lamp, or exterior light (although alternatively, the device may be enabled such a light source, such as led), which enables a jeweler or a standard user to see and distinguish, recognize or read the label on the brink of a precious stone. When using the user holds the lens near the eye, choosing the angle of the longest element in such a manner that the line of precious stone was in focus, and then tilts the device for surveillance in order to obtain a mirror reflection of the external light source (as opposed to a diffuse reflection). The specified edge of the screen, the most remote from the axial connection, you can compress the sludge is then pressed and move, when this lens is moved at a shorter distance due to the leverage effect. Magnifying lens will create a magnified, virtual and live image of the label, while maintaining the correct position of the label relative to the axis of the lens. The axial connection allows you to adjust the lens in relation to the brink of a precious stone, so the face is located in the sought position and essentially under a predefined angle with respect to the axis of the lens, and the device will maintain the relative positions of the lens and the face of the gemstone. The device adjusts the relative positions of the precious stone and lenses, allowing you to easily see the label. The rotation of the longest element also provides a focus adjustment axis. Fine focusing is very simple for the user compared with the location of loose precious stones or pieces of jewelry and a magnifying glass.

Thus, the device provides a simple way of seeing the label, and in the preferred embodiment, the location is indoor or outdoor lighting without the need for any additional light source. The light falls on the face obliquely, i.e. at an angle to the normal. The slanting rays of light can enhance the contrast of the die-cut labels, and in any case give the ability to easily see carved tag, use the I am the light, mirrored from the brink.

The lens may have any suitable optical power, for example, greater than the force corresponding to the increase about 2 times, or about 6 times, for example, less than the force corresponding to the increase of about 20 times or 16 times, but it was found that lens with 10x magnification will be given the opportunity to read most of the labels used in the industrial production. The axis of the lens, preferably located at a small angle to the normal to the line connecting the specified edge and the axis of the swivel, it is inclined to the normal direction of rotation when lifting longest element. The angle is preferably not less than approximately 2° and not more than about 8 or 10°.

This longest edge of the element and the specified axial connection can be at a distance from the axis of the lens, which, at least, two, three, four or five times more effective radius of the lens. The effective radius of the lens is part suitable for transmission of light. Preferably longest element has a significant size in all radial directions from the lens. In this case, the extended element can be effectively opaque or, at least, effectively opaque in relation to one is th wavelength range, and he can act as a screen, which improves the definition of the image by reducing scattered light, which would affect the image quality. If the screen is opaque with respect to only one range of wavelengths, then the label is visible is better, if it is observed only in this wavelength range, and by this arrangement, when the light source provides radiation only in this range or due to the presence on the path of the light beam filter, for example, associated with the lens. The screen is located so that substantially reduce stray light that would affect the image quality of the face. For example, the screen may have sizes in all radial directions relative to the axis of the lens, which, at least approximately five times or ten times more effective radius of the lens (i.e. a lens part, which is available for light transmission).

In a preferred embodiment of the device for monitoring, in accordance with the invention, can function as a normal case for jewelry and give the possibility to distinguish between a label on a face with the eyes, without any additional equipment. Thus, the device according to the invention may be in the form of case for jewelry containing the substrate, which has the lighting installation is sablania, necessary to secure a precious stone or products, as well as an extended element, which is a cover rotatable relative to the substrate, so that when the cover is closed, a precious stone or the product is inside a protective case. Case for jewelry can match described in claim 11 of the formula. However, alternatively, the device for monitoring does not need to be closed to form a cover for the gemstone or jewelry and can simply serve to monitor labels. For example, it may have open ends and can be positioned so that the necklace or bracelet can be moved so that every precious stone was placed under the lens and tested sequentially. In this case, the mounting device is designed to have a gemstone or article in a sustainable manner.

The hinged connection may be in the form of hinge or hinge bolts. However, this is not essential and in other embodiments, the location of the hinge connection can be created in any suitable way, for example, using a one-piece elastically deformable plastic hinge, which may be a connection, molded as a single unit with a screen and a device for setting a gemstone./p>

The dependent claims define arbitrary, preferred or alternative features of the invention.

The invention is further explained in the description of variants of its implementation with reference to the accompanying drawings, in which:

figure 1 is a front view of the holder for jewelry;

figure 2 is a side view of the holder for jewelry, showing the parts with dotted lines;

figure 3 is a section along the plane III-III shown in Fig 1; and

figure 4 is a top view of the holder for jewelry, with the remote cover.

The device 1 made in the form of case 1 for jewelry, has a substrate 2 and an extended element or screen in the form of a flap or cover 3, which rotates relative to the substrate 2 using a simple hinge bolt 4. The substrate 2 has a device 8 for installation in a certain position, and, specifically, for saving or fixing ring 5, framing gemstone 6, shown as a diamond with a diamond cutting and, as usual, with the face 7, which is at the top. The cover 3 can be opened to an angle slightly greater 90°for easy manipulation or removal from the holder ring 5. When the cover 3 is closed, creates a protective case.

The setting device 8 which is raised as a rotating holder, which has a circular cylindrical Cup 9, placed in a cylindrical recess of the substrate 2 and held in place with opposite him locking pins 10, schematically depicted upside-down strokes in a U-shape, which pass over the upper part of the corresponding pin 10 and go down on each side to the bottom of the cylindrical Cup 9 (see dotted contour lines in figure 2); the latch 10' pins 10 are in contact with the annular groove around the cylindrical recesses in the substrate 2. Cylindrical Cup 9 has a foam filling 11, which has an almost horizontal upper surface 12, which forms a decorative background for the ring 5 (the outer surface 12 has a slit for insertion of the ring 5, and a base 13 which may be the case 1. The filler 11 has a traditional cut to accommodate the ring 5, so the ring 5 can simply be placed on the spot and held by friction, and the ring 5 can be raised above and lowered below without effort, manually. Rotating the holder 8, on the other hand, can be located with the possibility of holding a separate gemstone or other jewelry, such as earrings, while maintaining the location of the gemstone with its upper edge on the axis of the case 1. During manufacture the Oia can be inserted into one of a number of different holders 8. Also, thanks to snap the pins 10, the holder 8 can be easily removed, and various holders 8 can replace already installed the holder 8.

The holder 8 has a protruding up the tab 14, which has the same thickness as the wall of a cylindrical Cup 9, the upper part of which acts as the device height adjustment made when choosing the desired height for the face 7 of precious stones; thus, the device height adjustment is fixed on the substrate 2. Height gem 6 can be adjusted to approximate the level of the face 7 of the upper part of the tongue 14, for easy observation, as explained below. By capturing the base 13 of the holder 8 can be rotated around the vertical axis of the substrate 2 to approximate installation gemstone under his observation.

The cover 3 has an opening or aperture 15 in its upper part, containing a magnifying lens 16. The cover 3 is of such length in all radial directions to the axis of the lens 16, which corresponds to a distance essentially five times greater than the radius of the aperture 15 (which is the effective radius of the lens 16). As shown in figure 3, the distance from the left edge 3' of the cover 3 (which is the edge of the cover 3, remote from the hinge bolt (4)), and from the hinge bolt (4) to the axis of the lens 1, respectively 6.6 and 6 times greater than the effective radius of the lens 16 from its axis. The cover 3 is held below the level of precious stone 6, when the cover 3 is closed, and has a notch 17 on the side opposite the hinge bolt, through which light can reach the brink of 7 precious stone, when the cover 3 is lifted. The upper part of the recess 17 is essentially straight, and the centers of the lens 16 and the upper part of the recess 17 is essentially located in a plane perpendicular to the axis of the hinge bolt (4) cover 3. The substrate 2 has an upward protrusion 18 which mates with the recess 17 when the cover 3 is closed. The arrangement is such that when the cover 3 is opened about 30° (as shown in figure 3), face gem 7 can be observed by eye through the lens 16 with precious stone 6, illuminated by the light passing under the edge of the cover 3, remote from the hinge bolt (4) and entering the case through the gap formed due to the opening of the cover 3 (shown by arrows on the right in figure 3), i.e. through the notch 17, when the light falls obliquely on the face 7 of the precious stone. The axis of the lens 16 coincides with the axis of the observations are shown with arrows on the right in figure 3, but is located at an angle of 15° in relation to the axis of the case 1 (when the cover 3 is closed) and angle 4° with respect to the line connecting the lower part of the region 3' and the axis of the hinge bolt (4). Figure 3 shows that the light falls on the face 7 at an angle of 45°and the axis is observed for the I-45° in relation to the face 7, so the reflected image will be visible through the light falling on the face 7 and reflected through the lens 16.

The substrate 2 and the cylindrical glass holder 9 can be obtained by injection molding of any suitable opaque plastic material such as Acrylonitrile butadiene-styrene, and the lid 3 can be obtained by injection molding the same material or, alternatively, a transparent acrylic resin. In the latter case, the cover 3 and the lens 16 can be molded as one unit; and a cover 3, excluding the lens 16 may be a spray-painted. Filling 11 of the holder may be made of foamed plastic, such as polyurethane foam, and may have a front surface 12 in the form of a colored synthetic velvet. The lens 16 can have a 10-fold increase. Lens 16 may be made of glass or plastic. To obtain a reflection of the size of the diameter of the base 13 may be 28 mm
