The present invention relates to a sandwiching structure for accessories.

The inventor has conventionally proposed a new earring.
First, in Japanese Patent Application Laid-Open No. 10-276810 (see Patent Document 1), a sandwiching member in which a main decorative body having a pair of mounting legs and a mounting base that fits between the pair of mounting legs are formed. Proposing an earring that provides clamping force when both are closed by inserting a washer between the mounting leg and the mounting base, penetrating them with a pin, and caulking the part did.

In the above-mentioned earring with a washer-like plate interposed, it can be attached to the earlobe without exerting such a large clamping force due to friction between the two, and contact with each other by repeatedly opening and closing the both. Although it is possible to prevent the mounting leg and the mounting base from being worn or deformed by contact friction to some extent, the problem that the clamping force tends to decrease during use still remains.

Accordingly, the present inventor has intensively studied, and in Japanese Patent No. 4592116 (Patent Document 2), a pair of mounting legs and a mounting base are formed on one main decorative body and the other sandwiching member, and the pair Earrings formed by interposing one or two smooth circular metal plates having elasticity between the mounting leg portions and the mounting base portions and attaching them to the shaft, and caulking the shaft portions together with the circular metal plate material The mounting base is formed with a width narrower than the diameter of the circular metal plate, and the mounting legs and the mounting base formed on one main decorative body and the other sandwiching member are relative to each other. The circular metal plate is bent inward at the intersection with the edge in the width direction of the mounting base due to a load applied to the contact portion with the mounting base, and the bent portion is the mounting base. To engage with the edge of the It proposed a lip-type earrings.

On the other hand, the inventor separately forms a pair of decorative portions and a projecting piece at one end of the decorative portion, and a branch portion sandwiching the projecting piece is formed at one end of the decorative portion, which can be rotated by a pin. The accessory is provided with a spring that restrains the inner peripheral surface and the tip surface of the projecting piece inside the decorative portion, and has a loop substantially formed by the decorative portion, and the branch portion on the inner peripheral side of the decorative portion A hook is provided, the tip protrudes from the branch part, and the middle part of the spring bent toward the inner peripheral surface of the decorative part is pressed against the inner peripheral surface of the decorative part by the hook. Japanese Patent No. 3806873 (Patent Document 3) proposes a sandwiching structure for an accessory in which a resilient force is applied to the tip of the spring.

JP-A-10-276810 Japanese Patent No. 4592116 Japanese Patent No. 3806873

As described above, in Japanese Patent No. 4592116 (Patent Document 2), a smooth circular metal plate having elasticity is interposed between the pair of mounting legs and the mounting base, and these are pivotally attached. An earring formed by caulking the shaft portion together with the metal plate material, wherein an outer edge of the circular metal plate material is in contact with the attachment base portion by making a diameter of the metal plate material larger than a thickness of the attachment base portion. It is possible to maintain a holding force when the earrings are closed for a long period of time when the earrings are closed by being flexed inwardly by a load applied to the portion and the bent portion engages with the end edge of the mounting base portion.
However, it has not been a fundamental solution to the problem that the clamping force tends to decrease during use.

The present invention improves the above-described drawbacks of the conventional accessory sandwiching structure, and includes the attachment as one or more smooth metal plates interposed between a pair of attachment legs and an attachment base. When the mounting leg and the mounting base formed on one main decorative body and the other sandwiching member are relatively rotated, the diameter is larger than the thickness of the base. The load applied to the metal plate material is applied to the engaging portion with the edge in the width direction of the mounting base, so that a large clamping force is obtained and it can be used for a long period of time. An object of the present invention is to make it possible to maintain a holding force when the main decorative body and the sandwiching member are closed with a leaf spring incorporated in the wearing member for a long period of time.

That is, according to the sandwiching structure of the accessory of the present invention, a pair of mounting legs and a mounting base are formed on one main decorative body and the other sandwiching member, and between the pair of mounting legs and the mounting base. 1 or a plurality of smooth metal plate members interposed between them, and these are attached to the metal plate material and the shaft portion is clamped together. When the mounting leg portion and the mounting base portion formed on each of the other sandwiching members relatively rotate, a large load is applied to the metal plate material,
In addition, a leaf spring is provided on the inner side of the main decorative body or the sandwiching member on the side of the attachment leg to suppress the inner peripheral surface and the distal end of the attachment base, and the leaf spring is connected to the width of the attachment base. The width is equal or narrower than that, and is housed between the metal plate members projected from both side surfaces of the mounting base.

In the sandwiching structure for jewelry according to the present invention, the metal plate material protruded from both side surfaces of the attachment base has a protruding width that can ensure engagement with the plate spring. is there.

In the sandwich structure for jewelry according to the present invention, the smooth metal plate has a thickness in the range of 0.1 to 0.3 mm.

As described above, in the present invention, a pair of attachment legs and attachment bases are formed on one main decorative body and the other sandwiching member, and 1 between the pair of attachment legs and attachment bases. A sandwich structure for a jewelry accessory comprising a sheet metal member or a plurality of smooth metal plate members interposed therebetween and caulking the shaft portion together with the metal plate member, wherein the one main decorative body and the other When the mounting leg and the mounting base formed on each of the sandwiching members of the metal plate relatively rotate, a large load is applied to the metal plate material, and the main decorative body on the mounting leg side Alternatively, the inner side of the sandwiching member is provided with a leaf spring that suppresses the inner peripheral surface and the tip portion of the mounting base, and the leaf spring is formed to have a width equal to or narrower than the width of the mounting base. Between the metal plate members protruding from both side surfaces of the mounting base In which was housed.
In other words, it is difficult to reduce the clamping force by the leaf spring and can maintain a constant clamping force during use, and the clamping force is maintained for a very long period of time. It was successful in fundamentally solving the problems related to the persistence of the clamping force.

Further, the metal plate material projected from both side surfaces of the mounting base is formed to have a projecting width capable of ensuring engagement with the leaf spring, and the metal projecting from both side surfaces of the mounting base When the plate spring is housed between the plate materials, the metal plate material guides the plate spring when the plate spring is attached to the inside of the main decorative body or the sandwiching member on the mounting leg side. The process can be performed very smoothly.
Of course, since the metal plate material prevents lateral blurring of the leaf spring, the leaf spring does not deviate from the inner peripheral surface of the mounting base and the joining portion of the tip portion, and a very high quality accessory sandwiching structure is provided. can do.

It is a schematic side view which shows one Example of the clamping structure of the accessory of this invention. It is a schematic perspective view of the state which opened the main decoration body and the clamping member. It is a schematic sectional drawing of the decomposition | disassembly state of a shaft attachment part. It is a schematic sectional drawing of the state which assembled | attached it. It is a schematic enlarged view of a shaft attachment part. It is a schematic enlarged view of the state which opened it.

Hereinafter, a case where the present invention is applied to a clip-type earring as an embodiment of a sandwiching structure for an accessory of the present invention will be described in more detail with reference to the drawings.

In the embodiment shown in FIGS. 1 to 6, 11 is a main decorative body, 12 is a sub-decorative body as an earlobe clamping member, and its overall shape is substantially the same arc shape, and in the assembled state, it is a ring shape In this example, a jewel 33 made of diamond or the like is attached to the front side. Of course, both may be worn with either side facing the front of the earlobe. Moreover, although the cross-sectional shape is a substantially square, it may be a so-called “circle” of arc shape. As materials, gold (K-18, etc.), platinum, silver, etc. can be used.
A pair of mounting leg portions 13 and 14 are integrally provided in the connecting portion of the main decorative body 11, and the fitting portion is fitted between the mounting leg portions 13 and 14 in the connecting portion of the sub-decorating body 12 in opposition thereto. The base 15 is integrally formed.

Then, the pin 18 is inserted into the through holes 16 and 17 opened in these, and this portion is caulked, but at this time, the thickness 0 between the mounting legs 13 and 14 and the mounting base 15 is reduced. .1 to 0.3 mm, preferably 0.15 mm thick made of stainless steel or the like, and crimped through one or more smooth metal plate materials 19 having cushioning properties.
The reason why the thickness of the smooth metal plate material 19 is in the range of 0.1 to 0.3 mm is that the elasticity cannot be utilized when the thickness is 0.1 mm or less. Further, when the thickness is 0.3 mm or more, the elasticity of the metal plate material 19 itself is lost.
One or more metal plate members 19 may be used. However, even if two metal plate members 19 are used, there is no problem in economic efficiency and assembling workability. desirable.
The metal plate 19 is circular, but may be oval or polygonal.
Reference numerals 30 and 31 denote ear pads formed on the end surfaces of the main decorative body 11 and the sub decorative body 12.

In this embodiment, the area of the smooth metal plate 19 is formed to have a diameter wider than the thickness of the mounting base 15 as shown in FIGS. Of course, there is no problem even if the thickness of the mounting legs 13 and 14 is substantially equal to the thickness of the mounting base 15 or larger than the thickness of the mounting base 15.
And when the attachment leg parts 13 and 14 and the attachment base part 15 which were each formed in one main decoration body 11 and the other sub decoration body 12 rotate relatively, the load concerning the said metal plate material 19 is the said. The mounting base 15 is engaged with the engagement portion with the end edge 32 in the width direction.

Further, in the present invention, a leaf spring 21 is provided on the inner side of the main decorative body 11 or the auxiliary decorative body 12 on the side of the mounting leg portions 13 and 14 to suppress the inner peripheral surface and the distal end portion of the mounting base portion 15. The leaf spring 21 is formed to have a width equal to or narrower than the width of the mounting base portion 15.
The leaf spring 21 is housed between the metal plate members 19 projecting from both side surfaces of the mounting base 15.
Note that the metal plate material 19 only needs to have a protruding width that does not release the engagement with the plate spring 21. For example, even if the metal plate material 19 has a protruding width smaller than the thickness of the plate spring 21, the engagement with the plate spring 21 is sufficient. If the match is not released, it is applicable.

More specifically, the shape of the leaf spring 21 of the present invention is generally L-shaped, and the tip of the L-shaped long piece is a portion protruding in the length direction between the mounting leg portions 13 and 14, and the L-shape is formed. The tip of the short piece is fitted into a concave groove provided on the inner peripheral surface of the main decorative body 11, and the intermediate portion of the L-shaped long piece is pressed against the inner peripheral surface side of the main decorative body 11 by the hook 22. It is something that is attached. A space 21d is formed on the rear side of the leaf spring 21 with the inner peripheral surface of the main decorative body 11, and the inner peripheral surface 15a of the mounting base 15 is pressed with elasticity at the tip 21a. It is.

The overall shape of the leaf spring 21 of the present invention is not limited to the above embodiment. The hook 22 is preferably formed at the intermediate portion 21 b of the leaf spring 21, and more desirably, the rear end 21 c of the leaf spring 21 is accommodated in a recess 11 a provided on the inner peripheral surface of the main decorative body 11. It is good.

The sandwiching structure of the accessory of the present invention has the above-described configuration, and the leaf spring 21 is always attached to the main decorative body 11 in a state in which elasticity is imparted to the leaf spring 21 due to the presence of the hook 22. Is. For this reason, it cannot be overemphasized that the mounting | wearing to an earlobe becomes reliable. The leaf spring 21 is provided with elasticity by the action of the hook 22 in advance. For this reason, the leaf spring 21 used in the present invention is smaller and weaker than the conventional one, and is soft. A tasteful spring characteristic will be obtained.

Since the rear end 21c of the leaf spring 21 is always pressed against the inner peripheral surface of the main decorative body 11, the rear end 21c functions to bite into the inner peripheral surface. For this reason, unlike the conventional spring, there is no drawback that it is pulled out during use, and it is not necessary to pay much attention when the leaf spring 21 is mounted, so that the assembling workability is extremely excellent.

Further, the plate spring 21 is formed in a width equal to or narrower than the width of the mounting base 15 and is housed between the metal plate members 19 protruding from both side surfaces of the mounting base 15. In short, the metal plate material 19 may be formed so as to have a protruding width that can ensure engagement with the plate spring 21. By doing so, the metal plate material 19 guides the leaf spring 21 when the leaf spring 21 is attached to the inside of the main decorative body 11 or the auxiliary decorative body 12 on the side of the mounting legs 13, 14. The assembly process can be performed very smoothly.
Of course, since the metal plate material 19 prevents the lateral vibration of the leaf spring 21, the leaf spring 21 is not displaced from the inner peripheral surface of the mounting base portion 15 and the joining portion of the tip portion, so that a very high quality accessory can be sandwiched. A landing structure can be provided.

By the way, in the conventional sandwiching structure of the accessory simply interposing a washer, the sandwiching force is reduced when it is repeatedly opened and closed several tens to several hundreds of times, whereas the sandwiching structure of the accessory in this embodiment However, even when the opening / closing operation was further performed, no decrease in the clamping force was observed, and the clamping force itself was much superior to the clamping structure of the conventional washer-type accessory.

As described above, when the mounting leg portion and the mounting base portion respectively formed on one main decorative body and the other sandwiching member are relatively rotated, the intermediate metal plate material is free. Thus, the load applied to the engagement surface of each metal plate material varies, so that the spring property is improved and the clamping force is kept constant for a long period of time.
Therefore, the present invention can be applied not only to the case where the arc-shaped pinching member as shown in the figure is used, but also to other designs, pinching structures of jewelry provided with pins for piercing, free size rings, bracelets, and the like. Needless to say.
