Description

The present invention relates to a sphere containing a rubber-like elastic material and a manufacturing method thereof. More specifically, the present invention relates to a chain for decoration / decoration in which a chain for decoration / decoration is inserted into a sphere containing a rubber-like elastic material so that the ball can slide, and a method for manufacturing the chain.

Inventor of the present invention, in the registered utility model No. 3042071, in order to produce a structure in which a chain for elastic material is inserted and slidable in a ball containing elastic material, the elastic material is inserted inside the hemisphere Thus, a manufacturing method was proposed in which a pair of hemispheres were butted together and brazed or laser welded together. Moreover, after manufacturing a hollow sphere, the manufacturing method which pushes in and pulls in well-known O-ring which is an elastic material from a small opening was also employ | adopted.

As a technology of other companies, in Patent No. 3114868, a plurality of disk-shaped elastic materials are incorporated by hooking a hook-like means using a wire etc. into a disk-shaped elastic material and introducing it into the inside through a small opening of a sphere. Technology has been proposed.

Registered Utility Model No. 3042071 Patent No. 3114868

However, in the method of inserting an elastic O-ring into a sphere as in Patent Document 1, if the sphere has an outer diameter of 3 mm, the O-ring is passed through a through hole of about 1 mm, but the O-ring is crushed with tweezers. Therefore, there is a problem that the O-ring is cut off or jumps out to the opposite side, which makes it difficult to work. Further, when the size of the O-ring does not match the chain, it is necessary to cut the outside of the O-ring with a press to adjust the cross section to a semicircular shape.

Another problem is that the orientation of the O-ring inserted into the sphere is not constant and stays inside the sphere at various angles and cannot pass through the chain as it is. It is necessary to correct the orientation of the O-ring. In the case of a chain having a size (cross-section) of 0.8 mm or less, since there is no small-diameter O-ring, for example, production is impossible unless custom-made in units of 100,000.

In addition, as in Patent Document 2, a method of hooking a wire or the like on a disk-shaped elastic material and introducing a plurality of pieces into a sphere is difficult to work and is not suitable for mass production. In particular, since a plurality of disk-shaped elastic materials are introduced, in the case of a sphere having a small outer diameter, manufacture becomes more difficult than in the case of Patent Document 1.

The technical problem of the present invention pays attention to such a problem, and does not introduce an elastic material such as an O-ring into a metal hollow sphere later, but manufactures a sphere containing an elastic material from the beginning. By making it possible, it is possible to solve problems associated with the later introduction of the elastic material into the sphere as described above.

The technical problem of the present invention is solved by the following means. According to the first aspect of the present invention, a solid or hollow pipe-like string-like body made of rubber or elastic resin is inserted into a metal pipe, and a plurality of continuous spheres are formed by a sphere manufacturing means, and then separated by a constricted portion. It is a manufacturing method of the ball | bowl with an elastic material characterized by these. Thus, according to the manufacturing method in which a large number of continuous spheres are formed by a known sphere manufacturing means with rubber or elastic resin string-like bodies inserted into a metal pipe, the elastic material is cut from the constricted portion from the beginning. Since a sphere in a state of containing can be manufactured, there are no problems that occur when an elastic material is subsequently inserted into a hollow sphere as in the prior art. In addition, since an opening is formed in the hollow sphere at the constricted portion, a through hole can be formed in the internal elastic material from this opening, or a chain or the like can be inserted.

According to a second aspect of the present invention, in the method for producing a ball with an elastic material according to claim 1, a through hole is formed in the elastic material inside the constricted portion after the constricted portion is separated or before the separation. is there. As described above, since an opening is formed in the metal sphere in the constricted portion, a through hole can be opened from the opening to the internal elastic material. Alternatively, before separating them one by one, in a plurality of continuous spheres, it is possible to simultaneously insert a drill from the constricted portion into the internal elastic material to open a through hole. A through-hole of an arbitrary size can be formed according to the drill diameter, and a fine through-hole can be opened by inserting a needle or a cone. When a hollow pipe-shaped elastic body is inserted to form a sphere, the confined portion has its own fine hole sealed, but it may be opened with a drill or the like.

Claim 3 is a completed sphere configuration, in a sphere formed by processing a metal pipe into which a solid or hollow pipe-like string made of rubber or elastic resin is inserted. An elastic material-containing sphere characterized in that an internal elastic material is exposed and visible in a formed opening. In this way, a sphere processed and formed with a metal pipe into which a string of rubber or elastic resin is inserted is completed with the internal elastic material exposed and visible in the opening of the separated constricted portion. Therefore, it is possible to purchase this ball, easily open a through-hole of a desired size in the exposed elastic material, and insert a chain or the like. Therefore, it is possible for the consumer to obtain the ball by himself and drill it to produce a chain with a favorite design.

Claim 4 shows that after forming a large number of continuous spheres with a metal pipe into which a solid or hollow pipe-like string made of rubber or elastic resin is inserted, the constricted portion is separated after or before the constricted portion. A through hole is formed in the internal elastic material, and a chain, string or wire is inserted into the through hole. In this way, after forming a large number of continuous spheres with a metal pipe into which a string made of rubber or elastic resin is inserted, through holes are formed in the internal elastic material at the constricted portion, and chains, strings or According to the manufacturing method of inserting a wire, since the elastic material is contained in the sphere from the beginning, it is freed from the troublesome work of introducing the elastic material into the sphere as in the past. It is also easy to make a small hole through which a thin chain or string can be inserted.

Claim 5 is a sphere formed of a metal pipe into which a solid or hollow pipe-shaped string made of rubber or elastic resin is inserted, and a chain, string or It is an ornament including the accessory characterized by inserting a wire. In this way, in a sphere formed of a metal pipe into which a string-like body made of rubber or elastic resin is inserted, a decoration tool formed by inserting a chain, a string body, or a wire into a through hole formed in an elastic material inside thereof is Since the ball is formed from a metal pipe with an elastic material from the beginning, there is no problem that the elastic material is cut or damaged, and the elastic material in the sphere may have pores opened from the constricted portion. Therefore, products with thin chains, strings and wires can be easily realized.

According to a manufacturing method in which a large number of continuous spheres are formed by a known sphere manufacturing means in a state where rubber or elastic resin string-like bodies are inserted into a metal pipe as in claim 1, and then separated by a constricted portion. Since the sphere in which the elastic material is contained can be manufactured from the above, various problems are not caused when the elastic material is subsequently inserted into the hollow sphere as in the prior art. In addition, since an opening is formed in the hollow sphere at the constricted portion, a through hole can be formed in the internal elastic material from this opening, or a chain or the like can be inserted.

Since the opening is formed in the metal sphere in the constricted portion as in claim 2, a through hole can be opened from the opening to the internal elastic material, but the perforation is cut one by one in the constricted portion. It may be performed later, or before separating one by one, in a plurality of continuous spheres, a drill can be inserted into the elastic material inside from the constricted portion to simultaneously open through holes. A through-hole of an arbitrary size can be formed according to the drill diameter, and a fine through-hole can be opened by inserting a needle or a cone. When a hollow pipe-shaped elastic body is inserted to form a sphere, the confined portion has its own fine hole sealed, but it may be opened with a drill or the like.

A ball formed by processing a metal pipe into which a string made of rubber or elastic resin is inserted as in claim 3 is completed in a state where the internal elastic material is exposed and visible in the opening of the separated constricted portion. To do. Therefore, it is possible to purchase this ball, easily open a through-hole of a desired size in the exposed elastic material, and insert a chain or the like. Therefore, it is possible for the consumer to obtain the ball by himself and drill it to produce a chain with a favorite design.

After forming a large number of continuous spheres with a metal pipe into which a string made of rubber or elastic resin is inserted as in claim 4, a through hole is formed in the internal elastic material at the constricted portion, and a chain is formed in the through hole. According to the manufacturing method of inserting a string or wire, since the elastic material is contained in the sphere from the beginning, it is freed from the troublesome work of introducing the elastic material into the sphere later as in the past. . It is also easy to make a small hole through which a thin chain or string can be inserted.

As in claim 5, in a sphere formed of a metal pipe into which a string of rubber or elastic resin is inserted, a chain, string or wire is inserted into a through hole formed in the elastic material inside the ball. Since the ornament is formed from a metal pipe with an elastic material from the beginning, the sphere is formed, so there is no problem that the elastic material is cut or damaged during the manufacturing process. Since the pores can be opened, products with thin chains, strings and wires can be easily realized.

Next, an embodiment of how the chain with the elastic material according to the present invention and the chain manufacturing method using the elastic material will be practically described. FIG. 1 is a perspective view showing a material for producing a ball containing an elastic material according to the present invention, and a metal pipe 1 as shown in (1) and a string-like body 2 made of an elastic material as shown in (2) are prepared. To do. The metal pipe 1 may be made of gold, may be made of silver or platinum, and the material is not particularly limited as long as it is a material suitable for decoration or decoration. The elastic material string 2 is made of rubber, but may be made of a synthetic resin having an appropriate hardness as long as the material is rich in elasticity like rubber. The hardness can be selected arbitrarily, and a sponge-like foamed resin can be used as necessary. The color of the elastic string-like body 2 is preferably substantially the same color as the metal pipe 1 or a similar color. The elastic string-like body 2 can be a hollow pipe-like body. When it is desired to increase flexibility, a hollow pipe-like body is preferable. This is because in the case of a solid string-like body, the entire surface of the through hole of the elastic material in the sphere is in contact with the chain or the string-like body, and the elasticity is so strong that it may be difficult to slide.

Using the metal pipe 1 and the elastic string-like body 2 shown in FIG. 1, the solid or hollow pipe-like elastic string-like body 2 is inserted into the metal pipe 1 as shown in FIG. Therefore, the inner diameter of the metal pipe 1 in FIG. 1 is larger than the outer diameter of the elastic string-like body 2. In this way, the metal pipe 1 with the elastic string-like body 2 inserted therein is set in a known ball manufacturing machine. As shown in FIG. 3, the ball manufacturing machine is a device that gradually forms a metal pipe 1 into a spherical shape by pressurizing a predetermined position from the outer periphery. That is, as shown in FIG. 3 (1), while applying pressure as indicated by arrows a 1 and a 2 from the outer periphery of the metal pipe 1 in a state where the elastic string-like body 2 is inserted, at the position to be the constricted portion, When the pipe 1 is continuously rotated in the direction of the arrow a3, as shown in (2), the portion that receives the pressure in the directions of the arrows a1 and a2 is gradually bundled.

When continuously rotating while applying pressure in the directions of arrows a1 and a2 to the constricted portion, the constricted portion gradually constricts further as shown in (2) → (3) → (4). Will be transformed into a continuous shape. Then, as shown in (4), when it is deformed into a substantially spherical shape, the pressurization in the directions of arrows a1 and a2 is stopped, the cutter is applied in the directions of arrows a1 and a2 and the constricted portion is cut. Thus, a plurality of spheres 1b are separated from the constricted portion and separated one by one.

In such a separated state, each metal ball 1b... Has an opening 1h in the separated portion. Further, when the metal pipe 1 is formed in a spherical shape, the internal elastic body 2 is deformed into a shape corresponding to the inner surface shape of the sphere 1b. For this reason, the internal spherical elastic body 2b is exposed in the openings 1h on both sides of the sphere 1b ..., but the product can be sold in this state and processed by the consumer himself. .

However, normally, with the internal spherical elastic body 2b exposed as described above, the drill 3 is advanced in the direction of arrow a4 in (5) to pass through the opening 1h, and a through-hole is formed in the internal spherical elastic body 2b. Open. FIG. 4 shows a state in which the chain 6 is inserted through the through hole 4 in the elastic body 2b inside the sphere 1b. In this way, the through-hole 4 is opened in the sphere 1b one by one with a drill or the like, but in the state where the spherical bodies are continuous as shown in FIG. By advancing a long drill, it is possible to open the through holes 4 in the spherical elastic bodies 2b. A chain line 4h indicates through-holes opened simultaneously. Thus, according to the method of simultaneously opening the through holes 4h in the balls 1b in a continuous state, the holes can be efficiently drilled and suitable for mass production. By selecting the thickness of the drill 3, the inner diameter of the through hole 4 can be freely set, and a fine through hole can be opened by inserting a needle or a cone.

When the sphere 1b is used, a chain 6, a string, a wire, or the like is inserted into the through hole 4 of FIG. 4 so that it can be slid relatively in the direction of the arrow a5. As a result, it becomes adjustable and can be used in various ways as shown in FIG. Depending on the application of the sphere 1b, it can be used as a product simply by opening the through hole 4 in this way, but depending on how it is used, the pulling ring 5 is laser welded. Further, the surface of the sphere 1b in FIG. 4 has a spherical shape, but it is formed into a polyhedral mirror ball as shown in FIG. 5 (1) by forming a large number of flat surfaces by a known processing technique. You can also. Alternatively, in the processing step of FIG. 3, by making the interval between the constricted portions longer, it can be processed into an elliptical sphere or a rugby ball-like deformed sphere as shown in FIG.

3, when a hollow pipe-like body is inserted as the elastic string-like body 2 to produce the sphere 1b, the cross-sectional shape after separation is as shown in FIG. That is, following the internal shape of the sphere 1b, the elastic body 2b also has a hollow, almost spherical shape. As a result, the hole 2h formed by converging both ends of the cylindrical shape remains in the constricted portion without opening a through hole in the elastic body 2b with a drill or the like, so that the chain resists the elasticity of the elastic body 2b. Etc. can be inserted. Of course, a through opening may be further opened in the constricted portion 2h with the drill 3 or the like. In any case, since the elastic body 2b has a hollow spherical shape, the elastic body 2b does not come into contact with the inserted chain 6 or the like in the hollow portion, and only the left and right constricted portions 2h are brought into contact with elasticity. It will be. As a result, the inserted chain 6 and the like are held with a relatively weak elasticity, and can be easily slid with a light force.

FIG. 7 is a diagram showing an example of usage of the sphere 1b manufactured as described above. As shown in (1), the chain 6 is inserted into the through hole 4 of the sphere 1b in FIG. A plate 7 is attached to one end, and a decoration 8 is attached to the other end. In use, with the chain 6 wound around the neck, the plate 7 is fitted and connected to the pulling ring 5 of the ball 1b. When the adjustable sphere 1b is slid toward the ornament 8, it becomes a large-diameter collar having a maximum length of about 45 cm as shown in (2), and when it is slid away from the ornament 8, it is about 35 cm long as shown in (3). It becomes a small diameter collar.

FIG. 8 shows an example in which two spheres 1b are used. As shown in FIG. 8 (1), the right end of the chain 6 inserted into the left sphere 1b is laser welded to the outer surface of the right sphere 1b. The left end of the chain 6 inserted through the right sphere 1b is laser welded to the outer surface of the left sphere 1b. Therefore, the left and right spheres 1b and 1b can be moved toward and away from each other by sliding in the left-right direction. FIG. 8 (2) is an example in which the two right and left spheres 1b and 1b are separated to the limit, and as a result, they can be used as, for example, a short double chain 6 or 6 having a length of about 19 cm. FIG. 8 (3) is an example in which the two right and left spheres 1b and 1b are brought close to each other, and the two chains 6 and 6 can be connected to be used as a long chain 6 having a length of about 38 cm. . In addition, it is also possible to enjoy by arbitrarily setting the interval between the left and right spheres 1b and 1b or changing the interval from time to time.

FIG. 9 shows an example in which a single chain 6, string, wire, or the like is inserted through a plurality of balls 1 b. And the diamond decoration 9 etc. are attached to the center ball | bowl 1b. That is, in a state where the chain 6 is inserted through a plurality of spheres 1b as shown in FIG. 9 (1), the spheres 1b are dispersed at equal intervals or at arbitrary intervals as shown in FIG. 9 (2). Each ball 1b... May be collected at the center of the chain 6 and used as shown in FIG.

As described above, according to the present invention, a method for producing a large number of spheres with a sphere production means in a state where a solid or hollow pipe-like string made of rubber or elastic resin is inserted into a pipe made of noble metal. Therefore, the material of the elastic body accommodated in the sphere is arbitrary, and can be manufactured very easily and inexpensively compared to the method of inserting an O-ring or the like into the sphere later. For this reason, it can be used as an adjustable part, and it can be expected to spread as an accessory or ornament made of a chain, string, wire, or the like that slides on a sphere. In addition, as ornaments, there are various uses such as straps and key chains for mobile phones and the like.
