Description

  The present invention relates to a fastener used for fastening a string-like body such as a chain in an accessory such as a necklace, and the structure of the fastener that can be used for adjusting the stop position of the string-like body for other purposes as well as the accessory About.

  In Patent Document 1, a fastener is shown in which an O-ring-shaped elastic body is housed in a spherical shell-shaped outer shell having two holes in the central axis direction. In Patent Document 2, a fastener is shown in which a tubular elastic body is housed in a sphere having two holes in the central axis direction. Further, Patent Document 3 discloses a fastener in which a tubular elastic body is housed in an oval casing made of a sealed cylinder except for a pair of holes. The fasteners according to these prior arts house an elastic body having a through hole in a casing made of a metal ball or a cylinder structure which is sealed except for a pair of holes, and the vicinity of the chain through hole is tapered. It consists of a structure that narrows down to. With this configuration, the chain is passed through the hole of the casing and the hole of the elastic body, and the chain can be stopped at an arbitrary position by the pressure of the elastic body.

  In Patent Document 4, a cylindrical elastic body made of elastic rubber provided with a through hole having a diameter smaller than the diameter of the string-like body to be inserted, and an insertion hole are provided so as to match the position of the through hole of the elastic body, It is composed of a cylindrical inner body that houses the elastic body, and an outer body that is provided with an insertion hole in the side wall so as to match the position of the insertion hole of the inner body, and the inner body can be accommodated in the body through the opening. Adjusters are shown. In the adjustment tool shown in Patent Document 4, the through hole for inserting the string-like body is arranged at a position eccentric from the center on the side surface of the cylindrical elastic body. For this reason, the pressure exerted on the string-like body by the elastic body becomes uneven, and when the string-like body is pulled and moved for position adjustment, a biased force acts on the elastic body so that the thin side is twisted. In order to solve this problem, the elastic body can be stably stored and retained by adopting a triple structure in which the elastic body is stored in the internal body. Like to do.

  In Patent Document 5, a friction body composed of a tubular body made of an elastic body having friction such as rubber and silicon is provided inside the hole formed on both sides of the decorative body, and a chain or the like is provided on the friction body. A configuration in which the elongated member is penetrated is shown. In this case, the friction body made of rubber, silicon or the like is configured to be directly attached to the decorative body.

JP 2000-50921 A JP 2000-139528 A Japanese Patent No. 3934872 JP 2007-117518 A Utility Model Registration No. 3041836

  In the fasteners shown in Patent Documents 1 to 3, an elastic body is first inserted into a spherical or cylindrical casing formed loosely in the vicinity of the chain through hole, and then pressure is applied from the outside of the casing. In general, a manufacturing process is generally employed in which the vicinity of the chain through hole of the casing is formed tightly and caulked to be tapered. Therefore, a strong pressure is always applied to the elastic body in the casing in the central direction of the elastic body at least in the vicinity of the chain through-hole of the casing, and the chain inserted into the through-hole of the elastic body A strong pressure is applied from the elastic body, and the elastic body is hard and deformed. Therefore, when trying to move the chain for adjusting the stop position, a relatively strong force and adjusting force are required for the initial movement, and fine fingertip use is required. Therefore, for users who are hard to apply force to their fingertips (for example, children, elderly people, or physically handicapped people), there is a fear that the joint parts of the chain will be damaged, and the function cannot be used effectively, making it easy to use. It was bad. In addition, generally, the movement tends to be hard, and there is a problem that the feeling of use is bad.

  As another example of the technique similar to Patent Documents 1 to 3, the entire vicinity of the chain passage hole at both ends of the cylindrical casing is formed in a tapered shape in advance, and the elastic tube is compressed into the chain passage hole of the casing. It is carried out by passing through the casing. In that case, there is no step of strongly caulking the vicinity of the chain through hole of the casing after the elastic tube is stored, and the elastic tube in the casing is not constantly compressed from the outside. However, when trying to move the chain to adjust the stop position, the elastic tube in the casing is first moved toward the chain hole in the casing, hits the taper near the chain hole, and then moves the chain As a result, a stronger pressure is applied along the taper toward the center of the elastic tube. For this reason, a strong compressive force is generated in the central direction of the elastic tube at the time of the initial movement of the chain, thereby increasing the initial resistance of the chain.

  When manufactured by any of the above methods, the fasteners of the type shown in Patent Documents 1 to 3 are left for several hours after the fasteners are moored at a desired position on the chain. Then, the elastic body in the fastener was in close contact with the outer shape of the chain, and the next time the chain was moved, the resistance at the time of initial movement became great, and it was difficult to move. Furthermore, there is also a problem that the elastic body is shaved due to the strong frictional force generated when the chain is moved, and shavings are easily generated. Further, when the elastic body is damaged or deteriorated, it is not easy to replace only the elastic body in the casing, and there is a problem that the maintainability is poor.

  On the other hand, the conventional technique disclosed in Patent Document 4 requires an inner body for stably storing an elastic body, and thus has a problem that a complicated triple structure is formed and manufacturing costs are increased.

  In the prior art disclosed in Patent Document 5, the friction body made of rubber, silicon, or the like is configured to be directly attached to the decorative body. It is clear that there is a lack of durability. Further, if no adhesive is used, it can only be attached by a known method as shown in Patent Documents 1 to 3 above, and there is the same problem as described above.

  The present invention has been made in view of the above-described points, and an object of the present invention is to provide a fastener having a structure in which resistance at the time of initial movement can be reduced when a string-like body fastened to the fastener is moved. It is another object of the present invention to provide a fastener having a structure in which smooth movement is easily obtained, shavings are not easily generated, and an elastic body can be easily replaced.

The fastener according to the present invention has an outer shape having a polygonal columnar shape, and an elastic body formed with a through hole for passing a string-like body in the center with an inner diameter smaller than the outer diameter of the string-like body to be applied. An upper and lower part in which a pair of holes having an inner diameter smaller than the outer diameter of the elastic body is provided corresponding to the arrangement of the through holes of the elastic body, and a left and right part connecting the upper and lower parts on both the left and right sides constituted by the in, a frame that is configured in a ring shape, and the frame space enclosed by the part of the left and right portions of the lower upper is that to form an opening sized to allow ingress and egress of the elastic member The elastic body is housed in the frame, and a string-like body is passed through the hole in a state where the pair of holes of the frame and the axis of the through hole of the elastic body are aligned with each other. The string-like body can be anchored at an arbitrary position by elastic force, and the elasticity Characterized in that it is possible to arbitrarily slides string-like body against the elastic force.

According to the present invention, since the opening of a size allowing the elastic body to enter and exit is formed in the frame, the elastic body may be introduced into the frame through the opening when the elastic body is accommodated in the frame. However, it is not necessary to strongly crimp (compress) the casing as in the prior art. In addition, there is no tapered portion (or a narrowed portion) in the frame that causes the elastic body to be tightened toward the center as the string-like body is moved. Therefore, the elastic body is not strongly compressed from the outside together with the casing, and therefore, the elastic body is not hardly deformed. As a result, only the usual elastic force of the elastic body is applied to the string-like body passed through the through hole of the elastic body, so that the string-like body is moved to adjust the stop position. A strong force is not required for the initial movement at the time, and it can slide smoothly and smoothly even in the process of moving the string-like body, and a soft feeling of use can be obtained. Further, since the frictional force generated when the string-like body is moved is not as strong as that of the conventional one, the elastic body is not shaved and shavings do not appear. In addition, when the elastic force is deteriorated due to the breakage of the elastic body or the like, it is easy to replace only the elastic body, so that the maintainability is good. In addition, since a conventional process of strongly caulking a metal casing containing an elastic body from the outside is unnecessary, the number of assembling steps is reduced and the cost is reduced. Moreover, since it has a simple structure, it is suitable for small lot production. Furthermore, the elastic body has a polygonal columnar outer shape, and has a structure in which a through hole for passing the string-like body is formed in the center with an inner diameter smaller than the outer diameter of the string-like body to be applied. For the string-like body, pressure is applied substantially uniformly from the entire inner wall of the through hole of the elastic body, and it is not a configuration in which extremely strong pressure is applied only to a specific portion. There is little resistance at the time of initial movement when moving the, and it has an excellent effect that it can be moved smoothly thereafter.
Further, according to the present invention, the frame includes not only the upper and lower portions formed by providing a pair of holes having an inner diameter smaller than the outer diameter of the elastic body corresponding to the arrangement of the through holes of the elastic body, Since the left and right parts that connect the upper and lower parts are configured in a ring shape, the frame is configured in a ring shape as a whole, and there is strength and distortion is unlikely to occur. In particular, when the string-like body is slid, the upper and lower parts of the frame are firmly supported by the left and right parts, so there is no risk of damage. In addition, when wearing, one side of the ring-shaped frame (one of the left and right parts) or the entire edge of the ring-shaped frame will come into contact with the wearer's skin, and the corners are difficult to touch, so the touch should be improved Can do.

  The fastener according to the present invention according to another aspect is an elastic body in which a through hole for passing a string-like body is formed in the center as a polygonal column space having a diameter smaller than the outer diameter of the cord-like body to be applied. A pair of holes having an inner diameter smaller than the outer diameter of the elastic body corresponding to the arrangement of the through holes of the elastic body, and forming an opening of a size that allows the elastic body to enter and exit. The elastic body is housed in the frame, and the string-like body is inserted into the hole in a state where the pair of holes of the frame and the axis of the through hole of the elastic body are aligned. The string-like body can be moored at an arbitrary position by the elastic force of the elastic body, and the string-like body can be arbitrarily slid against the elastic force of the elastic body. To do. In this case, the same operation and effect as described above can be achieved.

  According to still another aspect of the present invention, there is provided a fastener according to the present invention, wherein a plate-like elastic body in which a through hole for passing a string-like body is formed with an inner diameter smaller than the outer diameter of the cord-like body to be applied; A pair of holes having an inner diameter smaller than the outer diameter of the body, corresponding to the arrangement of the through holes of the elastic body, and an opening having a size allowing the elastic body to enter and exit; The elastic body is housed in the frame, and a string-like body is passed through the hole in a state in which the pair of holes of the frame and the axis of the through hole of the elastic body are aligned. The string-like body can be anchored at an arbitrary position by the elastic force of the body, and the string-like body can be arbitrarily slid against the elastic force of the elastic body. In this case, the same operation and effect as described above can be achieved.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1A shows an example of the elastic body 1, and FIG. 1B shows an example of the frame 2. The elastic body 1 has a quadrangular columnar shape having a through hole 1a through which a string-like body passes, and is made of a material such as silicon or rubber. For example, the elastic body 1 can be easily manufactured by cutting out the elastic body 1 with a desired length from a rectangular silicon-made or rubber-like material. The frame 2 is formed by arranging two struts 2c and 2d between a pair of rings 2a and 2b having through holes 3a and 3b, respectively, and connecting them to each other. Made of hard material. Further, for example, a ring-shaped attachment 2e is fixed to the support 2c or other appropriate part of the frame 2. When used as a fastener for high-grade jewelry such as a necklace, a precious metal such as gold, silver, or platinum is appropriately used as the material of the frame 2.

  In the frame 2, a space surrounded by the rings 2 a and 2 b and the columns 2 a and 2 b forms an opening 8 having a size that allows the elastic body 1 to enter and exit. The size of the opening 8 may be exactly the same as the outer size of the elastic body 1, or may be somewhat larger or sufficiently larger than that, or may be somewhat or moderately smaller than that. May be. That is, when the size of the opening 8 is equal to or larger than the outer size of the elastic body 1, the elastic body 1 is stored in the frame 2 without any obstacle when the elastic body 1 is stored in the frame 2. On the other hand, when the size of the opening 8 is somewhat or moderately smaller than the outer size of the elastic body 1, the elastic body 1 is appropriately compressed and deformed when the elastic body 1 is stored in the frame 2. Then push it in.

  The elastic body 1 is accommodated in the frame 2 in such an arrangement that the through holes 1a of the elastic body 1 coincide with a pair of through holes 3a, 3b provided in the rings 2a, 2b of the frame 2. When the elastic body 1 is stored in the frame 2, the elastic body 1 may be stored in the frame 2 through the opening provided in the frame 2, so that it can be easily stored. As shown in FIG. 1C, the elastic body 1 is housed in the frame 2 as described above, and the pair of through holes 3a and 3b of the frame 2 and the axes of the through holes 1a of the elastic body 1 are aligned. Then, the string-like body 4 is passed through the through hole 3 a provided in the ring 2 a of the frame 2, the through hole 1 a of the elastic body 1, and the through hole 3 b provided in the ring 2 b of the frame 2. The inner diameter of the through hole 1 a of the elastic body 1 is a size that is somewhat or moderately smaller than the outer diameter of the string-like body 4. Thereby, the string-like body 4 inserted into the through hole 1a can be anchored at an arbitrary position by the elastic force of the elastic body 1, and the string-like body 4 is resisted against the elastic force of the elastic body 1. You can also slide arbitrarily. In this case, since the pressure is applied to the string-like body 4 from the entire inner wall of the through hole 1a of the elastic body 1, the configuration is not such that a very strong pressure is applied only to a specific portion as in the prior art. When the body 4 is moved, there is little resistance at the time of initial movement, and it can be moved smoothly thereafter. Further, the inner diameter of the pair of through holes 3a and 3b provided in the rings 2a and 2b of the frame 2 is larger than the outer diameter of the string-like body 4 and smaller than the outer diameter of the elastic body 1. . Thereby, the elastic body 1 which let the string-like body 4 pass does not remove | deviate from the flame | frame 2 in the axial direction of the through-hole 1a. Note that the outer diameter of the elastic body 1 having a polygonal cross section refers to the length of the longest portion of the radiation passing through the central portion of the polygonal cross section.

  The storage space in the frame 2 for storing the elastic body 1 may exactly match the outer size of the elastic body 1, or may be somewhat larger or moderately larger than that, or more than that. May be somewhat or moderately small. When the storage space in the frame 2 is exactly the same as or larger than the outer size of the elastic body 1, no pressure from the outside is applied to the elastic body 1 while being stored in the frame 2. In that case, the pressure applied to the string-like body inserted into the through hole 1 a of the elastic body 1 is based only on the inherent elastic force of the elastic body 1. When the storage space in the frame 2 is somewhat or moderately smaller than the outer size of the elastic body 1, that is, the ring 2a, 2b or the column 2c, 2d is sized so as to press the elastic body 1 somewhat or moderately. In such a case, the elastic body 1 is somewhat or moderately pressured from the outside by the frame 2 in the state of being housed in the frame 2, but the entire casing from the outside at the time of assembly as in the conventional product. Since it is not caulked (compressed) strongly, it does not cause excessive compression as found in conventional products to the elastic body 1 and there is no problem. Further, unlike the conventional product, the entire vicinity of the through hole at both ends of the casing is not preliminarily tapered so that the elastic body 1 becomes the taper portion (or the restrictor of the casing) as the string 4 is moved in the axial direction. The problem that the cross section of the through hole 1a is compressed from all directions toward the center does not occur.

  In the example of FIG. 1C, one end of the string-like body 4 is connected to the fixture 2e, and the other end of the string-like body 4 is connected to the through hole 1a of the elastic body 1 and the through holes 3a, 3b of the frame 2. This shows an application example in which the string-like body 4 can be formed in a ring shape. Such an application example is suitable when the fastener of the present invention is configured as a fastener for forming a metal chain of an accessory such as a necklace or a bracelet in a ring shape.

  In the example of FIG. 1 (c), the elastic body 1 is generally arranged so that the corners of the elastic body 1 are in contact with the columns 2c and 2d. However, the present invention is not limited to this, and as shown in FIG. It is good also as arrangement | positioning that the side part of 1 touches support | pillar 2c, 2d. The rings 2a and 2b are not limited to the quadrangular shape as shown in the figure, and may be circular, or may have a configuration in which through holes 3a and 3b are provided in a flat plate. Further, the number of support columns 2c and 2d is not limited to two, and may be three or four.

  Thus, according to the present invention, the elastic body 1 is not strongly squeezed (compressed) together with the frame 2 from the outside, and as the string-like body 4 is moved, the elastic body 1 becomes harder toward the center. Since there is no taper portion (or narrowed portion) that can be tightened in the frame 2, the elastic body 1 is not deformed hard or the like. As a result, the string-like body 4 passed through the through hole 1a of the elastic body 1 is only subjected to a pressure approximately equal to the normal elasticity of the elastic body 1. A strong force is not required for the initial movement when trying to move the string 4, and it can be moved smoothly and smoothly even in the process of moving the string 4, so that it is soft to use. Can be obtained. Therefore, even the person with weak fingertip force can easily adjust the stop position of the string-like body 4. Further, since the frictional force generated when the string-like body 4 is moved is not as strong as the conventional one, the elastic body 1 is not scraped and shavings do not appear. Further, when the elastic force is deteriorated due to breakage of the elastic body 1 or the like, the damaged elastic body 1 can be removed from the frame 2 and the new elastic body 1 can be easily stored in the frame 2 through the opening of the frame 2. Therefore, it is possible to easily replace only the elastic body 1, and the maintenance is good. In addition, since a conventional process of strongly caulking a metal casing containing an elastic body from the outside is unnecessary, the number of assembling steps is reduced and the cost is reduced. Moreover, since it has a simple structure, it is suitable for small lot production. Further, when each of the structural members 2a to 2e of the frame 2 is formed of a linear member as in the example of FIG. 1, a casing such as a spherical shell or a cylinder that covers the entire outside of the elastic body as in the prior art is provided. Since it is unnecessary, when the frame 2 is made of a noble metal, the frame 2 of the present invention can reduce the amount of noble metal used, resulting in lower costs.

  When the elastic body 1 is formed of silicon or the like, when a transparent material is used, a skeleton feeling can be obtained in combination with the frame 2 formed of a linear member, and the design is rich. For example, when the string-like body 4 is moved, it is possible to visually recognize the movement of the string-like body 4 through the transparent elastic body 1, and a new ground can be opened as an accessory. Further, even if the elastic body 1 is formed of a translucent or opaque material colored with an arbitrary color such as red or blue, the design is rich.

  The shape or structure of the frame 2 is not limited to the example shown in FIG. 1, but can be variously changed as long as the configuration defined in the claims is satisfied. Further, a plurality of elastic bodies 1 may be provided in a common frame so that a plurality of string-like bodies can be fastened. Hereinafter, these modifications will be described.

  In the example of FIG. 2 (a), the frame 5 is composed of one flat ring, and a pair of through holes 5a and 5b are formed in the diameter direction of the ring, and a tube is formed between the pair of through holes 5a and 5b. The elastic body 1 is disposed. A circular space of the frame 5 that is formed in a ring shape as a whole is an opening that allows the elastic body 1 to enter and exit. 5c is an attachment.

  In the example of FIG. 2B, the frame 6 is composed of a flat rectangular ring made up of only four sides of a plate material, and a pair of through holes 6a and 6b are formed on two opposite sides of the rectangular ring. A tubular elastic body 1 (FIG. 1 (a)) is disposed between the through holes 6a and 6b. A rectangular space of the frame 6 that is formed in a rectangular ring shape as a whole is an opening that allows the elastic body 1 to enter and exit. 6c is an attachment.

Two elastic bodies 1 may be provided in one frame. Further, not limited to the example which houses two elastic bodies 1 in one frame, may be provided in conjunction with more than two elastic body 1. In such a case, three or more elastic bodies 1 may be arranged side by side in a row, or three or more elastic bodies 1 may be bundled together. For example, fasteners that features a plurality of elastic bodies 1 in one such frame is applied in one string-like body jewelry which is adapted to form a plurality of loops from (chains) 4 decorate fingers and wrists Suitable for doing.

The shape or structure of the frame for which houses a plurality of the elastic member 1, those skilled in the art, can be considered various forms. For example, stone I be features a plurality of elastic member 1 in a circular (or length may be circular) ring-like frame 5, as shown in FIG. 2 (a), as shown in FIG. 2 (b) A plurality of elastic bodies 1 may be provided together with a rectangular ring-shaped frame 6. Alternatively, a configuration in which a plurality of skeleton frames 2 as shown in FIG.

In addition, in the fastener composed of only one elastic body 1 as shown in FIGS. 1, 2 (a) and 2 (b), an appropriate ornament is attached to any surface other than the opening. Good.
In addition, as shown to Fig.3 (a), you may make it cover the whole side surface of the elastic body 1 with the cover 10. FIG. The cover 10 is made of, for example, a metal, a synthetic resin, or a noble metal that is the same material as the frame 2. In this case, the elastic body 1 covered with the cover 10 is accommodated in the frame 2 as shown in FIG. 1C through the opening 8 of the frame 2. In the type that features a multi several elastic body 1, it may be covered by a cover 10 separately for each elastic body 1, or, as shown in FIG. 3 (b), a plurality of elastic 1 may be covered with a common cover 10.

  Further, the polygonal column shape of the elastic body 1 is not limited to a quadrangular column, but a triangular column shape as shown in FIG. 4A, a hexagonal column as shown in FIG. 4B, or as shown in FIG. Any cross-section star shape (a shape having a zigzag outer peripheral contour) may be used (the polygonal column shape includes a cross-section star solid). The through-hole 1a for passing the string-like body is not limited to a circular cross section, and may be a polygonal cross section (including a star shape) such as a square cross section. Note that the diameter (inner diameter) of the through hole 1a of the elastic body 1 having a polygonal cross section refers to the length of the shortest portion of the radiation passing through the central portion of the polygonal cross section.

  FIG. 5 shows the elastic body 11 in the second embodiment of the present invention. The elastic body 11 has a cylindrical outer shape, and a through hole 11a for passing the string-like body 4 is formed in the center as a polygonal column space having a diameter smaller than the outer diameter of the string-like body 4 to be applied. It is made. The diameter (inner diameter) of the through hole 11a of the elastic body 11 having a polygonal cross section refers to the length of the shortest portion of the radiation passing through the central portion of the polygonal cross section. In the example shown in FIG. 5A, the cross-section of the through-hole 11a is a quadrangular cross-section. However, the cross-section is not limited to this, and a four-star cross-section as shown in FIG. It may be a rectangular cross section or any other polygonal cross section (polygon includes a star shape). In addition, the external appearance of the elastic body 11 is not necessarily limited to a cylindrical shape, and may be an arbitrary shape such as a spherical shape or an elliptical spherical shape.

  In the embodiment of FIGS. 1 to 5, the axial size of the elastic bodies 1 and 11 may be substantially equal to the radial size, or the axial size is relatively smaller than the radial size. It may be short. FIG. 6 shows an example. In FIG. 6A, the elastic body 1 is substantially square (the size in the axial direction is substantially equal to the size in the radial direction), and in FIG. 6B, the elastic body 1 is a flat plate. (The axial size is relatively shorter than the radial size). In the illustrated example, for example, the frame 60 is composed of a flat rectangular ring made of only four side plates as in the example of FIG. 2B, each having a through hole 60a as shown, and the size of the elastic body 1. It has an opening and an internal space adapted to.

  FIG. 7 shows an elastic body 12 in the third embodiment of the present invention. This elastic body 12 is an O-ring shaped elastic body in which a space (through hole) 12a for passing the string-like body 4 is formed in the center with an inner diameter smaller than the outer diameter of the cord-like body 4 to be applied. Consists of. That is, the cross section of the O-ring shaped elastic body 12 is circular. In this case, for example, the frame 61 can be formed of a flat rectangular ring made of only four side plates as in the example of FIG. 6B, and has a through hole 61a as shown in the figure. It has an opening and an internal space suitable for the size of the elastic body 12. Of course, the frame may be formed in other shapes.

  In each of the above embodiments, by adjusting the inner diameter of the through holes 1a, 11a, 12a in the elastic bodies 1, 11, 12 or adjusting the outer diameter of the elastic bodies 1, 11, 12, the elastic bodies 1, 11, 12 The thickness of 11 and 12 is adjusted, the elastic force given to the string-like body 4 is adjusted, so that the resistance feeling when the string-like body 4 is moved can be adjusted, and a suitable feeling of use is realized. be able to.

  As a use of the fastener according to the present invention, it can be used as a fastener for adjusting the length of a chain of accessories such as a necklace, a bracelet, and an anklet, and can also be used in place of an opening / closing metal fitting. In addition, the fastener of the present invention in which two string-like bodies can be applied can be applied as a fastener for adjusting the length of a loop tie. Or it can also be applied as a fastener for adjusting the length of a loop tie necklace. Further, when applied to a double necklace, the length of each chain can be variably adjusted. In addition, it can be used for adjusting the length of the string-like body or adjusting the stop position of various accessories such as earrings, earrings, rings, tiaras, brooches, bandages, men's jewelry (tie chains, tie bars, tie tacks, cuffs, etc.).
