[0008]

[Action]

 In the mounting mechanism for accessory according to the above structure, the first member and the second member attached to both ends of the connecting member are joined by the magnetic force of the magnet, and the tapered wall portion and the tapered portion are tapered to each other. Is a closed annular body. This closed ring can be worn like a well-known necklace or bracelet. For example, if a neckless chain or the like is used as the connecting member, the accessory mounting mechanism itself becomes the accessory. Also, a pendant top or the like can be attached to the connecting member.

Since the accessory can be mounted only by joining the first member and the second member with magnetic force, no special work such as operation of fine parts is required, and the accessory can be easily mounted. Further, the first member and the second member are tapered by the pair of taper wall portions whose distance becomes narrower as they move away from the connecting portion with the connecting member and the tapered portion whose width becomes narrower on the connecting portion side with the connecting member. Since they are matched with each other, even if an external force such as pulling the connecting member acts, this force acts in a direction in which the taper alignment is bitten. Therefore, even if such an external force acts, the joining of the first member and the second member is not released, and the necklace chain or the like does not drop from the user's body.

Next, if the tapered wall portion is formed as a bent portion as described in claim 2, its processing is easy. Here, the bent portion does not necessarily mean that it is formed by bending, and any processing method such as casting, plastic working, and injection molding may be used as long as the shape after processing is in a bent state.

Further, as described in claim 3, when the tapered wall portion is provided with the protrusion protruding toward the opposite tapered wall portion, the first member and the second member are separated from each other in the above-mentioned joined state. Even when an external force acts in the direction of separating, the protruding portion prevents the separation of the two, so the first member and the second member are separated and separated from each other by such an external force, and the necklace chain or the like is worn on the user's body. Never fall out of.

Further, with the configuration according to claim 4, the processing for forming the protrusion is easy.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. (Embodiment 1) As shown in FIG. 1, an accessory mounting mechanism 10 of the present embodiment includes a neckless chain 12 as a connecting member and a neckless chain 12 connected to an end of the necklace chain 12 through a connecting hole 14a. The second member 16 is connected to the first member 14 through the connecting hole 16a, and the accessory wearing mechanism 10 itself has a necklace function as the accessory.

The first member 14 is made of steel, the surface thereof is nickel-plated, and both side portions are bent to form a pair of tapered wall portions 18a and 18b. The distance between the tapered wall portions 18a and 18b is wide on the side of the connecting hole 14a and narrows as the distance from the connecting hole 14a increases.

On the other hand, the second member 16 is made of cast alnico magnet, has a surface plated with nickel, and is magnetized to the N pole and the S pole shown by the solid line in FIG. 1B. The second member 16 has a substantially trapezoidal shape in which the width on the side of the connecting hole 16a is narrow and widens as it moves away from the connecting hole 16a, and the side surface portion corresponding to the hypotenuse of the trapezoid is the tapered wall portion 18a of the first member 14, The tapered portions 20a and 20b are aligned with the space of 18b. The plate thickness of the second member 16 is set to be thinner than the depth of the recess 22 formed by the tapered walls 18a and 18b in the first member 14 (= the height of the tapered walls 18a and 18b). ing.

Although not shown, the first member 14 side and the second member 16 side of the necklace chain 12 are continuous. A well-known pendant top (not shown) or the like can be attached to the necklace chain 12. When mounting the accessory mounting mechanism 10 around the neck, for example, the necklace chain 12 is rotated around the neck in the same manner as in the conventional case with the first member 14 and the second member 16 separated from each other. The 1st member 14 and the 2nd member 16 are mutually approached, and both are joined by the magnetic force of the 2nd member 16. At this time, the relative positions of the first member 14 and the second member 16 are, for example, in the positional relationship shown by the two-dot chain line in FIG. Subsequently, the first member 14 is relatively moved along the arrow Q direction, or the second member 16 is relatively moved along the arrow P direction. Since this relative movement is movement along the joint surface, the magnetic resistance is relatively weak, and a strong force is not required for relative movement. As a result, the tapered wall portions 18a and 18b of the first member 14 and the tapered portions 20a and 20b of the second member 16 are tapered. In this way, the first member 14 and the second member 16 are joined together by magnetic force and are also connected by tapering, and the first member 14, the second member 16 and the necklace chain 12 form a closed annular body.

To remove the mounted accessory mounting mechanism 10, for example, the first member 14 and the second member 16 are respectively held by fingers, and the first member 14 is moved in the direction of arrow P and the second member 16 is moved. Relative movement is made in the direction of arrow Q to cancel the taper alignment between the two. Further, the movement may be continued to release the joining by the magnetic force, or the force may be applied in a direction to separate the two to release the joining by the magnetic force.

As described above, in the accessory mounting mechanism 10, the mounting and dismounting of the accessory does not require any special work such as operation of fine parts, and the mounting and dismounting can be easily performed. 12 may get caught in some obstacle. In such a case, the external force acting on the necklace chain 12 pulls the second member 16 in the arrow P direction shown in FIG. 1 and pulls the first member 14 in the arrow Q direction. That is, such an external force acts in a direction in which the taper alignment between the first member 14 and the second member 16 is further eroded, and the connection between the two is further strengthened. Therefore, even if such an external force is applied, the joined state between the first member 14 and the second member 16 is not released, and the necklace chain 12 does not drop from the user's body.

Further, as shown in FIG. 1B, when the accessory mounting mechanism 10 is used (the first member 14 and the second member 16 are joined to each other), a wide portion of the second member 16 is used. Are surrounded by the first member 14. As is well known, since the magnetic force lines have a property of easily passing through a portion having a high magnetic permeability, the magnetic force lines emitted from the N pole of the second member 16 are routed from the tapered wall portion 18a to the tapered wall portion 18b. It will pass 14 and reach the south pole. Therefore, if the plate thickness of the first member 14 is set to a value that does not cause magnetic saturation, the effect of preventing leakage flux will be sufficient. Although this plate thickness depends on the performance of the magnet used, 0.1 mm or more, preferably 0.5 mm or more is sufficient.

Since the surface of the second member 16 is nickel-plated, various metal components contained in the magnet do not come into direct contact with the skin or the like. Similarly, for example, sweat and the like do not come into contact with and react with these metal components. Therefore, there is no risk of skin being roughened by the metal that is the component of the magnet.

In the above example, the second member 16 is made of cast alnico magnet. Since cast magnets are not brittle, they are easy to machine and have the advantage of being able to drill connection holes 16a and surface-finish by barrel polishing, but if the magnet thickness (distance N pole-S pole) is thin, demagnetization occurs. It may be easy to do. Therefore, in the above example, the polarity is shown by the solid line in FIG. 1B in order to increase the magnet thickness and reduce the demagnetization.

On the other hand, when using a magnet such as a ferrite magnet or a rare earth magnet that is hard to lose magnetism even when the magnet thickness is thin, it is effective to magnetize as shown by the broken line in FIG. 1 (b). Is. In this case, the magnetic force lines once come out from the N pole into the air, and then reach the S pole from the tapered wall portions 18a and 18b through the first member 14, but the effect of preventing the leakage magnetic flux does not pose a practical problem. .

In the above example, the first member 14 is a magnetic body and the second member 16 is a magnet. However, a method of mixing magnetic powder in resin and molding it like a conventional plastic product and then magnetizing the same is used. If adopted, a magnet having a complicated shape can be manufactured. Therefore, it is possible to use the first member 14 as a magnet by this method. Therefore, a combination in which the first member 14 is a magnet and the second member 16 is a magnetic body, and a combination in which both the first member 14 and the second member 16 are magnets are possible. (Example 2) This example is an example in which a protruding portion is provided on the tapered wall portion.

As shown in FIG. 2, the accessory mounting mechanism 50 of the present embodiment includes a neckless chain (not shown) as a connecting member, and a first member connected to an end of a necklace chain through a connecting hole 54a. 54 and the second member 56 connected through the connection hole 56a, and the accessory mounting mechanism 50 itself has a necklace function as the accessory.

The first member 54 is made of steel, the surface of which is nickel-plated, and both sides thereof are bent to form a pair of tapered wall portions 58 a and 58 b. The upper ends of the tapered wall portions 58a and 58b are bent so as to project toward the opposite tapered wall portions 58a and 58b, and projecting portions 59a and 59b are formed. The distance between the taper wall portions 58a and 58b is wide on the side of the connecting hole 54a and becomes narrower as the distance from the connecting hole 54a increases.

On the other hand, the second member 56 is made of cast alnico magnet, has a surface plated with nickel, and is magnetized to the N pole and the S pole shown by the solid line in FIG. 2B. The second member 56 is composed of a strip-shaped arm portion 57a provided with a connecting hole 56a and a head portion 57b connected to the arm portion 57a on the side remote from the connecting hole 56a. The head portion 57b has a substantially trapezoidal shape in which the width on the side of the arm portion 57a is narrow and the width increases as the distance from the arm portion 57a increases, and the side surface portion corresponding to the hypotenuse of the trapezoid corresponds to the tapered wall portions 58a and 58b of the first member 54. The taper portions 60a and 60b are aligned with the space. Further, as shown in FIG. 2B, the plate thickness of the second member 56 is set to be thinner than the distance S between the base portion 54b of the first member 54 and the protruding portions 59a, 59b.

A well-known pendant top (not shown) or the like can be attached to the necklace chain. In using the accessory mounting mechanism 50, as in the first embodiment, the first member 54 and the second member 56 are separated from each other, and the necklace chain is wound around the neck, for example, in the same manner as in the conventional case, and then the first member 54 and the second member 56 are separated. The 1st member 54 and the 2nd member 56 are mutually approached, and both are joined by the magnetic force of the 2nd member 56. At this time, the relative positions of the first member 54 and the second member 56 are, for example, the positional relationship shown by the two-dot chain line in FIG. Subsequently, the first member 54 is relatively moved along the arrow Q direction, or the second member 56 is relatively moved along the arrow P direction. Since this relative movement is along the joint surface, the magnetic resistance is relatively weak, and a strong force is not required for relative movement. As a result, the tapered wall portions 58a and 58b of the first member 54 and the tapered portions 60a and 60b of the second member 56 are tapered. In this way, the first member 54 and the second member 56 are joined together by magnetic force and are also connected by tapering, and the first member 54, the second member 56 and the necklace chain form a closed annular body.

To remove the wearing accessory mounting mechanism 50, for example, the first member 54 and the second member 56 are respectively held by fingers, and the first member 54 is moved in the arrow P direction and the second member 56 is moved. Relative movement is made in the direction of arrow Q to cancel the taper alignment between the two. Further, the movement may be continued to release the joining by the magnetic force, or the force may be applied in a direction to separate the two to release the joining by the magnetic force.

As described above, the accessory mounting mechanism 50 does not require special work such as operation of fine parts when mounting and dismounting the accessory, and can be easily mounted and dismounted. May get caught in some obstacle. In such a case, the external force acting on the necklace chain pulls the second member 56 in the arrow P direction shown in FIG. 2 and pulls the first member 54 in the arrow Q direction. That is, such an external force acts in a direction in which the taper between the first member 54 and the second member 56 is further bitten, and the connection between the two is further strengthened. Therefore, even if such an external force is applied, the joined state of the first member 54 and the second member 56 is not released, and the necklace chain does not drop from the user's body.

Moreover, since the protrusions 59a and 59b provided on the tapered walls 58a and 58b restrict the movement of the second member 56 in the arrow R direction shown in FIG. Even if an external force acts such that the second member 56 is peeled off from the first member 54 along the arrow R, such peeling between the first member 54 and the second member 56 is prevented, so that it is more reliable. You can hold jewelry (necklace chain) on your body.

In addition, also in the second embodiment, the same effect of preventing the leakage magnetic flux as in the first embodiment can be obtained. Further, as in the first embodiment, a magnet, such as a ferrite magnet or a rare earth magnet, which does not easily lose magnetism even when the magnet thickness is thin, is magnetized as shown by the broken line in FIG. A combination in which the first member 54 is a magnet, the first member 54 is a magnet, and the second member 56 is a magnetic body by a method in which magnetic powder is mixed with resin and molded and then magnetized. A combination in which both members 56 are magnets is also possible.

In addition, the effect of preventing contact between the magnet component and the skin by plating the surface of the magnet and the effect of preventing the occurrence of defects due to contact between the magnet component and sweat or the like are the same as in Example 1. Although the attachment mechanism of the present invention has been described above according to the two embodiments, the present invention is not limited to these embodiments and can be variously implemented without departing from the gist of the present invention.

For example, it goes without saying that magnets other than cast magnets, ferrite magnets, and rare earth magnets can be used as the magnets. In addition to the above-mentioned nickel plating, plating such as gold plating may be applied to the surface of the magnet, or the same effect as described above can be obtained by providing a coating film of melamine, Teflon (trade name) or the like. Of course, both plating and coating may be applied. An adhesive was used to fix the magnet to the substrate in the above embodiment, but it is sufficient to fix the magnet to the substrate by the magnetic force of the magnet.

As the magnetic body, in addition to the steel shown in the examples, magnetic stainless steel and other well-known magnetic bodies can be used. It is preferable that the height of the tapered wall portion does not fall below the plate thickness of the other tapered portion, but the above effect is exhibited even if the height of the tapered wall portion falls slightly below the plate thickness of the tapered portion. .

[0035]

[Effect of device]

 As described above, the accessory mounting mechanism of the present invention prevents the bonded state of the accessory mounting mechanism from being released even when an external force such as pulling on the necklace chain is applied, and the accessory mounting mechanism is not broken during use. There is no inconvenience such as being released.

Next, as described in claim 2, if the tapered wall portion is formed as a bent portion, the processing is easy. Further, when the tapered wall portion is provided with a protruding portion that projects toward the opposite tapered wall portion as in claim 3, a direction in which the first member and the second member are separated from each other in the above-described joined state. Even if an external force is applied to the neck, the protruding portion prevents the peeling of the two, so the first member and the second member are peeled and separated from each other by such an external force, and the necklace chain or the like falls off the user's body. There is no such thing.

Further, according to the structure of the fourth aspect, the processing for forming the protruding portion is easy.
