Abstract

PROBLEM TO BE SOLVED: To provide a ring allowing a ring wearer to obtain extraordinary wear feeling, i.e., fitting feeling when putting the ring on his/her finger, and having small anxiety elements such as falling.SOLUTION: A ring is produced by making a shape of a ring wearer's finger on which the ring is put on into digital data with a highly precise 3D scanner and measuring, trimming the shape of the ring to a shape tightly fitting to the finger of a ring wearer on the 3DCAD, performing jewel and surface decoration, and using a 3D printer and lost wax casting, and enables obtaining extraordinary wear feeling and safety feeling by making a jewel and a surface decoration portion hardly rotate.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a ring made in a shape that fits an individual person's finger.

  Many common rings are manufactured with a substantially circular shape inside the ring that touches the finger.

  This is due to the reason that a perfect circle shape is easy to manufacture, the reason that adjustment is easy when adjusting the size, and a plurality of reasons that the perfect circle is visually acceptable.

  However, even if the ring is a perfect circle, the person's finger is not a perfect circle, so if you wear a ring with a gem or decoration as mentioned above, it will rotate on the finger. In addition, there is a problem that bothering the gems and decorations and the trouble of the user correcting the position each time.

  Although there is an oval shaped ring as seen in Japanese Patent Laid-Open No. 8-168405, the shape of a human finger cannot be incorporated into one shape called an ellipse. Is the current situation.

JP-A-8-168405

  The present invention solves the above-mentioned problems, and provides a ring that can provide a fit with any finger shape and is difficult to rotate a jewel part or a decoration part.

  In order to solve the above-described problems, in the present invention, a finger of a person who wants to wear a ring or a molded finger mold is measured as digital data using a 3D scanner, and a detailed numerical value of the finger is obtained. Made it possible to produce a ring that fits.

  Moreover, in this invention, since the digital measurement data of the finger can be stored for a long period of time, a new ring that fits the finger can be newly created at any time as long as no major physical change appears once the measurement is performed.

  Since the ring according to the present invention is created based on precise numerical values, it fits on the finger and the position of the jewel part and the decoration part is difficult to rotate.

  According to the present invention, since the ring is created with precise numerical values based on the shape of the finger measured as digital data by the 3D scanner, almost all the finger surfaces in contact with the ring can feel the same wearing feeling, It has become possible to provide a ring in which the position of jewels and decorative parts is difficult to rotate with respect to the finger.

It is a completed drawing of this invention.

It is the figure of the finger data and ring which were measured with the 3D scanner of this invention.

  First, digitize the finger of the person who wants to wear the ring with a 3D scanner, and obtain detailed numerical values such as finger width and thickness, and node height.

  The detailed numerical values described above may be numerical values obtained by converting a finger mold obtained by shaping a finger of a ring wearer with resin or the like into digital data using a 3D scanner.

[Example 1]
The finger wearer's finger shape data obtained by the 3D scanner is taken into a three-dimensional CAD, and a ring reference line is created with substantially the same shape and dimensions as the finger epidermis on which the ring is worn.

  Next, using the created ring reference line, create the shape of the part that touches the epidermis of the finger, the shape that becomes the side of the ring, and the shape of the front side of the ring, that is, the part that has gems and decorations, on the 3D CAD software. The entire configuration is performed.

  After the entire structure of the ring is completed on 3D CAD, the frame for fixing the jewels and the decoration to be applied to the surface of the ring are also manufactured on 3D CAD.

  After the shape configuration to be a ring is created on 3D CAD, a work that can be output as a 3D by a 3D printer is added, and 3D output is performed with an extension corresponding to the 3D printer.

  The shape output as a solid by the 3D printer is directly made into metal by lost wax casting, or a replica mold called a rubber mold is produced so that a plurality of pieces can be produced, and then casting is performed with metal by a lost wax manufacturing method.

  The surface of the ring that has been made as a metal solid by lost wax casting is accompanied by the roughness of the gypsum particles used in the lost wax manufacturing method and the part where the metal called the runner flows, so these are polished. .

  The ring created as a metal solid by lost wax casting has the shape of the finger of the wearer of the ring, so it is not a perfect circle like a general ring, but has a curved shape at several places. .

  Therefore, when polishing the ring of the present invention, it is necessary to use extreme caution so that the shape completed from the lost wax casting can be maintained.

  In addition, the ring that has been polished and fixed with the necessary jewels is plated with a metal material to obtain a finished product.

  At first glance, the ring of the present invention completed as a finished product has a shape that is distorted by pressure after use, but it can be confirmed that it is a unique shape and a ring with a very elegant curve. .

  When the finished ring was put on the finger of the ring wearer, it was really excellent wearing feeling, and there was a sense of security that the jewelry and decorative parts would not move on the finger even if the entire arm was moved violently It was a thing.

  In addition, in order to measure the finger of the person who actually wears it with the 3D scanner in order to wear the ring described so far, the finger mold of the wearer of the ring is taken in advance with a resin for molding, etc. The same result can be obtained even if the finger mold is measured with a 3D scanner and converted into digital data.

  Furthermore, recently, there is a service such as Autodesk 123D Catch that creates or generates three-dimensional data from a plurality of images taken with a digital camera, so digital data of a finger using such a service can be obtained. Even if used, the same result as described above can be obtained.

  The ring of the present invention measures the shape of the finger of the ring wearer using a high-precision 3D scanner, and uses the digital data of the finger to produce the ring with 3D CAD, so it fits the finger and is used for jewelry and decoration It has become possible to provide a safe ring in which the part is difficult to rotate and the ring is not easily removed from the finger.

Claims (3)

A ring with a jewel or decoration on the surface, which is made with a numerical value that is almost the same as the numerical value of the finger of the ring wearer, which is obtained by measuring the inner diameter of the ring directly in contact with the finger to be worn as digital data with a 3D scanner. The ring according to claim 1, which is made after a wearer's finger mold is made of a resin for molding, and the finger mold molded based on the mold is measured as digital data by a 3D scanner. Claim 1 wherein the wearer's finger is photographed with a digital camera from a plurality of directions, and is produced using data generated by an individual or a company that provides a service for creating three-dimensional data based on the photographed images.
