The present invention relates to an ornament and a method of manufacturing the same, and more particularly to an ornament used in a hanging state as a necklace an earring and the like and a method of manufacturing the same.
A spherical hanging ornament whose front surface is specified is known. As shown in
In this type of the ornament, when it is worn by a body, it is necessary that the ornament faces a definite and unchanged direction. When, for example, the ornament is worn by a body in the above example, the affinity of the ornament is reduced by half unless the diamond faces the front at all times when it is viewed from a user.
However, when a through-hole is formed to an ornamental spherical body itself and a wire member is inserted thereinto, the spherical body turns around the hanging wire member and is liable to change its direction.
In view of the above circumstances, an object of the present invention is to provide an ornament whose direction is not changed when it is used in a hanging state and a method of manufacturing the same.
To solve the above problem, an ornament according to the present invention is characterized by comprising a spherical body with a through-hole, wherein the through-hole is formed by connecting through a first hole and a second hole that are drilled toward the center of the spherical body from right-left symmetrical positions in the upper half section of the spherical body, and a curved surface is formed by cutting off the vertex section of an inclined angle formed in the spherical body by the first hole and the second hole. The “upper half section” in the spherical body is a relative section that is arbitrarily determined by a manufacturer of the ornament in the present invention.
According to the present invention arranged as described above, the through hole is formed in a right-left symmetrical shape in the upper half section of the spherical body as well as the center of gravity of the spherical body is located in the lower half section of the spherical body when the spherical body is hung by inserting the hanging wire member in the through-hole. As a result, since the spherical body is unlike to turn around the hanging wire member, the directions of the front and the back of the spherical body do not change. Accordingly, there can be provided an innovative ornament by, for example, burying a jewel in the front of the spherical body or by burying different jewels in both the front and the back thereof. Further, since the curved surface is smoothly formed in the through-hole, the hanging wire member can be inserted into the through-hole very easily.
A method of manufacturing an ornament according to the present invention is characterized by comprising a step of drilling a first hole and a second hole toward the center of a spherical body material from right-left symmetrical positions in the upper half section of the spherical body material until they are connected to each other, and a step of forming a curved surface by cutting off the vertex section of the included angle formed in the spherical body material by the first hole and the second hole.
As a preferable embodiment of the method of manufacturing the ornament, the vertex section may be cut off by inserting a tool from respective openings of the first and second holes after the diameters of the openings of the first and second holes are enlarged. The above arrangement is preferable because the tool can be easily inserted from the respective openings toward the vertex section.
An ornament according to an embodiment of the present invention is characterized by comprising a spherical body with a through-hole and a hanging wire member inserted into the through-hole, wherein the through-hole is formed by connecting through a first hole and a second hole that are drilled toward the center of the spherical body from right-left symmetrical positions in the upper half section of the spherical body, and a curved surface is formed by cutting off the vertex section of the included angle formed in the spherical body by the first hole and the second hole.
A method of manufacturing an ornament according to an embodiment of the present invention is characterized by comprising a step of drilling a first hole and a second hole toward the center of a spherical body material from right-left symmetrical positions in the upper half section of the spherical body material until they are connected to each other, a step of forming a curved surface by cutting off the vertex section of the included angle formed in the spherical body material by the first hole and the second hole, and a step of inserting the hanging wire member up to an opening of the second hole by inserting an end of a hanging wire member from an opening of the through-hole and by sliding the hanging wire member along the curved surface while displacing the spherical body material.
According to the manufacturing method, since the curved surface is formed by cutting off the vertex section in the spherical body material, the hanging wire member can be easily inserted from the first hole into the second hole, which is bent and connected to the first hole, by sliding the hanging wire member along the curved surface while displacing the spherical body material.
As shown in
As shown in
The first and second holes 1, 2 are formed straight until they are connected to each other at the center S of the spherical body material P. Accordingly, the first hole 1 and the second hole 2 extend obliquely downward in the upper half section U from the surface of the spherical body material P, respectively, and the through-hole 10 is formed in a right-left symmetrical V-shape in the upper half section U of the spherical body material P. However, actually, since the trace of the extreme end of the tool, which was formed when the first hole 1 was drilled, and the trace of the extreme end of the tool, which was formed when the second hole 2 was drilled, remain, the first hole intersects the second hole at the center S of the spherical body material P.
In
When the first hole 1 is connected to the second hole 2 in a communicating section 3 in the spherical body material P, an included angle formed in the spherical body material P has a vertex section 4 projecting downward. When the inclination angle of the first hole 1 with respect to the horizontal surface is set to 30° and the inclination angle of the second hole 2 with respect to the horizontal surface is set to 30°, the inclined angle is 120°. In the embodiment, a curved surface 5 is formed by cutting off the vertex section 4 of the included angle subsequent to the hole drilling step. The vertex section cutting-off step is carried out to easily carry out a job for inserting the hanging wire member 6 into the through-hole 10 by smoothly forming the bent section of the through-hole 10. A job for cutting off the vertex section 4 can be carried out by inserting a cutting tool having a diameter smaller than that at the hole drilling step into the first and second holes 1, 2.
As shown in
In the cutting-off job of the vertex section 4, the vertex section 4 is cut off little by little and made smooth by inserting a tool into the first and second holes 1, 2. Although the tool is the same type as the tool used in the above hole drilling step, its diameter is smaller than the tool. Since the diameters of the opening sections 1a, 1b are expanded, the tool can be tilted more deeply in the first and second holes 1, 2, thereby the cutting-off job of the vertex section 4 can be easily carried out. The spherical body D is completed as shown in
After the completion of the vertex section cutting-off job, reinforcing cylinder members 7 are fixedly disposed in the enlarged opening sections 1a, 1b. The cylinder members 7 protect the opening sections 1a, 1b as well as guide the hanging wire member 6 inserted into the through-hole 10. Further, the ornamental element such as the diamond 8 or the like is attached to the spherical body D at a position which becomes the front of the spherical body D when it is hung by the hanging wire member 6.
As shown in
The ornament manufactured as described above can be used as a necklace as shown in, for example,
According to the ornament, the through-hole 10 is formed in the upper half section of the spherical body D in the right and left symmetrical state as well as when the spherical body D is hung by inserting the hanging wire member 6 into the through-hole 10, the center of gravity of the spherical body D is located on the lower half section of the spherical body D. As a result, since the spherical body D is unlike to turn around the hanging wire member 6, the directions of the front and the back of the spherical body D do not change. Accordingly, a problem that the diamond 8 is hidden, and the like do not arise. Further, since the curved surface 5 is smoothly formed in the through-hole 10, the hanging wire member 6 can be inserted into the through-hole 10 very easily.
