しかしながら、上記したイヤリングでは、以下のような問題点があった。すなわち、写真を２つの透明な部材により挟み込むため、中にある写真は、透明な部材に覆われた状態となる。そのため、装飾物として飾られた写真を透明な部材ごしにしか見ることができず、写真を直に見たときの色彩や光沢が失われるという問題がある。また、この従来技術では、花や宝石等の立体的なものを装飾物としてイヤリングに施すことはできないという問題点がある。 However, the above-described earrings have the following problems. That is, since the photograph is sandwiched between two transparent members, the photograph inside is covered with the transparent member. Therefore, there is a problem that a photograph decorated as an ornament can be seen only through a transparent member, and the color and gloss when the photograph is viewed directly are lost. In addition, this conventional technique has a problem that three-dimensional objects such as flowers and jewelry cannot be applied to the earrings as decorations.

装飾プレート２は、略正方形の軽量の板材であって、平面又は立体を問わず、さまざまな装飾物７を表面２ａに施すことができるものである。この装飾プレート２の表面２ａにのり等の接着剤で、例えばかすみ草、ミニローズ、やぐるま草等の花を貼付したり、宝石やビーズ等を貼付したりして装飾物７を施したものを複数枚用意しておけば、髪型や服装、外出目的やその時の気分に合わせて装飾プレート２を交換してお洒落を楽しむことができる。また、装飾プレート２に施された装飾物７を除却して新たに装飾物７を施し直すこともできる。 The decorative plate 2 is a substantially square lightweight plate material, and can apply various decorative objects 7 to the surface 2a regardless of a plane or a solid. With an adhesive such as glue on the surface 2a of the decorative plate 2, for example, a flower such as a haze grass, a mini rose, or a black bear grass was affixed, or a decoration 7 was applied by affixing a jewel or a bead. If you prepare multiple items, you can enjoy the fashion by exchanging the decorative plate 2 according to your hairstyle, clothes, purpose of going out and the mood at that time. Further, the decoration 7 applied to the decoration plate 2 can be removed and the decoration 7 can be applied again.

基台３は、図１に示すように、表面３ａに装飾プレート２を嵌め込むための凹状部３ｂが形成された板材であり、装飾プレート２を載置するためのものである。この基台３の素材としては、軽量で、且つ、直接耳たぶＥに触れるので肌に刺激の少ないアクリルやシリコン樹脂等の素材が好ましい。なお、耳たぶＥに沿うように裏面３ｃが湾曲していてもよい。 As shown in FIG. 1, the base 3 is a plate material in which a concave portion 3 b for fitting the decorative plate 2 is formed on the surface 3 a, and is for placing the decorative plate 2. As a material for the base 3, a material such as acrylic or silicone resin that is light in weight and directly touches the earlobe E and is less irritating to the skin is preferable. The back surface 3c may be curved along the earlobe E.

枠体４は、図２に示すように、装飾プレート２の装飾物７が見えるように、円盤の中央部分４ａが円形に開口したドーナツ状の形体をした部材であり、前記装飾プレート２の表面２ａの周囲を前記基台３に押え付けるためのものである。この枠体４のサイズは、イヤリング１を耳たぶＥに装着した際に美しく見えるような適度なサイズで、且つ、前方から装飾プレート２の周囲及び基台３が見えないように、枠体４の外縁４ｂは基台３よりも大きく、内縁４ｃは装飾プレート２よりも小さいサイズとしている。素材としては、金、銀、プラチナ等であったり、母材の表面にメッキを施したものであったりさまざまなものを用いることができるが、敏感肌の人にも金属アレルギー等のかぶれを生じさせない素材とするのが望ましい。なお、この枠体４にも装飾が施されていてもよく、例えば、ダイヤ等の宝石が埋め込まれていたり、彫金等の装飾が施される等の立体的なものでも、絵画等の平面的なものでもよい。 As shown in FIG. 2, the frame 4 is a member having a donut-like shape in which the central portion 4 a of the disk is opened in a circular shape so that the decoration 7 of the decoration plate 2 can be seen. This is for pressing the periphery of 2a against the base 3. The size of the frame 4 is an appropriate size so that the frame 4 can be seen beautifully when the earring 1 is attached to the earlobe E, and the periphery of the decorative plate 2 and the base 3 cannot be seen from the front. The outer edge 4 b is larger than the base 3, and the inner edge 4 c is smaller than the decorative plate 2. Various materials such as gold, silver, platinum, etc., or the surface of the base material plated can be used as the material, but people with sensitive skin may also experience rashes such as metal allergies. It is desirable that the material is not allowed The frame 4 may also be decorated. For example, a three-dimensional object such as a diamond or a three-dimensional object such as engraving or the like may be used. It may be anything.

丁番５は、図１及び図３に示すように、基台３と枠体４を開閉自在に結合する結合具であり、基台３の側面３ｄと枠体４の裏面４ｄの外縁４ｂ付近にろう付け等で固定されている。この丁番５は、図３に示すように、装飾プレート２を基台３の凹状部３ｂに嵌め込んで載置し、基台３と枠体４を閉じた際に、枠体４の裏面４ｄの外縁４ｂと内縁４ｃの間の部分により装飾プレート２の表面２ａの周囲を基台３に押え付けるものである。また、基台３の周囲が枠体４側から見えなくなるように設けられる。このため、図２に示すように、イヤリング１を耳たぶＥに装着した際に、イヤリング１の前方からは装飾プレート２の周囲及び基台３が見えないシンプルで美しい外観とすることができる。 As shown in FIGS. 1 and 3, the hinge 5 is a coupler that connects the base 3 and the frame 4 so as to be freely opened and closed, and is near the outer edge 4 b of the side surface 3 d of the base 3 and the back surface 4 d of the frame 4. It is fixed by brazing. As shown in FIG. 3, the hinge 5 is placed on the back surface of the frame 4 when the decorative plate 2 is fitted and placed in the concave portion 3 b of the base 3 and the base 3 and the frame 4 are closed. The periphery of the surface 2a of the decorative plate 2 is pressed against the base 3 by a portion between the outer edge 4b and the inner edge 4c of 4d. Moreover, the periphery of the base 3 is provided so that it cannot be seen from the frame 4 side. Therefore, as shown in FIG. 2, when the earring 1 is attached to the earlobe E, a simple and beautiful appearance in which the periphery of the decorative plate 2 and the base 3 cannot be seen from the front of the earring 1 can be achieved.

耳止具６は、図３に示すように、枠体４に設けられてイヤリング１を耳たぶＥに挟止するようにバネ筒６ａによって耳たぶＥの裏側方向に付勢されたものである。このバネ筒６ａは、耳止具６の一端側に設けられて、枠体４の裏面４ｄの丁番５が固定された側と反対側の外縁４ｂ付近にろう付け等で固定されている。耳止具６は、耳たぶＥの裏側に沿うように湾曲した形状の板材であり、直接耳たぶＥに触れる部分であるので、肌に刺激の少ない素材を選択して使用する。 As shown in FIG. 3, the ear stopper 6 is provided on the frame body 4 and is urged toward the back side of the earlobe E by a spring cylinder 6 a so as to clamp the earring 1 on the earlobe E. The spring cylinder 6a is provided on one end side of the ear fastener 6 and is fixed by brazing or the like in the vicinity of the outer edge 4b opposite to the side on which the hinge 5 of the back surface 4d of the frame body 4 is fixed. The ear stopper 6 is a plate material having a curved shape along the back side of the earlobe E, and is a portion that directly touches the earlobe E, so a material that is less irritating to the skin is selected and used.

以下、イヤリング１の装着手順について説明する。まず、装飾物７が表面２ａに施された装飾プレート２を基台３の凹状部３ｂに嵌め込んで載置する。次いで、丁番５により結合された基台３と枠体４を閉じて枠体４の裏面４ｄを基台３の表面３ａに合わせる。この状態において、装飾プレート２の周囲は、枠体４の裏面４ｄによって基台３に押え付けられている。そして、図３に示すように、枠体４の裏面４ｄを基台３の表面３ａに合わせた状態で基台３の裏面３ｃと耳止具６により耳たぶＥを挟んでイヤリング１を耳たぶＥに挟止することによって装着する。このイヤリング１の装着時において、基台３は、耳たぶＥを介して枠体４と耳止具６により挟まれた状態となっており、装飾プレート２が凹状部３ｂから容易に外れ難くなっている。 Hereinafter, a procedure for attaching the earring 1 will be described. First, the decorative plate 2 having the decorative object 7 applied to the surface 2 a is fitted into the concave portion 3 b of the base 3 and placed. Next, the base 3 and the frame body 4 joined by the hinge 5 are closed, and the back surface 4 d of the frame body 4 is aligned with the front surface 3 a of the base 3. In this state, the periphery of the decorative plate 2 is pressed against the base 3 by the back surface 4 d of the frame body 4. Then, as shown in FIG. 3, the earring 1 is put on the earlobe E with the earlobe E sandwiched between the rear surface 3 c of the base 3 and the ear fastener 6 with the back surface 4 d of the frame 4 aligned with the front surface 3 a of the base 3. Wear by pinching. When the earring 1 is mounted, the base 3 is sandwiched between the frame body 4 and the ear fastener 6 via the earlobe E, so that the decorative plate 2 is not easily detached from the concave portion 3b. Yes.

以上の説明からも明らかなように、本実施の形態に係るイヤリング１によれば、髪型や服装、外出目的やその時の気分に合わせて装飾プレート２を交換したり、装飾プレート２に施された装飾物７を除却して新たに装飾物７を施し直すことにより１つのイヤリング１でさまざまなお洒落を楽しむことができる。また、装飾プレート２に施される装飾物７は、花や宝石等の立体的な装飾物７であってもよい。更に、施された装飾物７の持つ色彩や光沢を直に鑑賞できる。 As is clear from the above description, according to the earring 1 according to the present embodiment, the decorative plate 2 is exchanged or applied to the decorative plate 2 according to the hairstyle, clothes, purpose of going out, and mood at that time. By removing the decoration 7 and applying the decoration 7 again, it is possible to enjoy various styles with one earring 1. The ornament 7 applied to the ornament plate 2 may be a three-dimensional ornament 7 such as a flower or a jewel. Furthermore, it is possible to directly appreciate the color and gloss of the ornament 7 that has been applied.

なお、本発明は上記実施形態に限定されるものではなく、本発明の要旨の範囲内で種々の変形実施が可能である。例えば、枠体４は、円形のドーナツ状の形体をなすものを用いて説明したが、これに限定されず、四角形等の多角形や、図４に示すように、楕円形であってもよく、また、図５に示すように、ハート型等の形体をしていてもよい。また、装飾プレート２の形体も略正方形に限定されず、円形や多角形等その他の形体としてもよく、また、枠体４の形体に合わせた形体とした場合、図４に示すように、枠体４の外縁４ｂと内縁４ｃの幅を狭くできて、イヤリング１全体に対して装飾物７を施すことが可能な範囲を広くでき、より好ましい。 In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, the frame 4 has been described using a circular donut-shaped shape. However, the frame 4 is not limited to this, and may be a polygon such as a rectangle or an ellipse as shown in FIG. Moreover, as shown in FIG. 5, it may have a shape such as a heart shape. Further, the shape of the decorative plate 2 is not limited to a substantially square shape, and may be another shape such as a circle or a polygon. When the shape is matched to the shape of the frame 4, as shown in FIG. The width of the outer edge 4b and the inner edge 4c of the body 4 can be reduced, and the range in which the ornament 7 can be applied to the entire earring 1 can be increased, which is more preferable.

また、基台３と枠体４を結合する結合具として丁番５を用いているが、図６に示すように、基台３の丁番５が固定された側と反対側の表面３ａに係止用突起３ｅを、枠体４の裏面４ｄに前記係止用突起３ｅに対応する係止用溝４ｅをそれぞれ形成し、基台３と枠体４を閉じて基台３の表面３ａと枠体４の裏面４ｄとが合わさる際に係止用突起３ｅと係止用溝４ｅが嵌合するようにして、係止用突起３ｅと係止用溝４ｅにより丁番５が容易に開かないようにしてもよい。これによって、イヤリング１を装着していないときであっても不意に枠体４が開いて装飾プレート２が基台３の凹状部３ｂから外れることを防ぐことができる。 Moreover, although hinge 5 is used as a coupling | bonding tool which couple | bonds the base 3 and the frame 4, as shown in FIG. 6, the surface 3a on the opposite side to the side where the hinge 5 of the base 3 was fixed is shown. The locking projection 3e is formed on the back surface 4d of the frame body 4 with a locking groove 4e corresponding to the locking projection 3e, and the base 3 and the frame body 4 are closed to close the surface 3a of the base 3 The locking projection 3e and the locking groove 4e are fitted when the back surface 4d of the frame 4 is brought together, and the hinge 5 is not easily opened by the locking projection 3e and the locking groove 4e. You may do it. Thereby, even when the earring 1 is not worn, it is possible to prevent the frame body 4 from opening unexpectedly and the decorative plate 2 from coming off from the concave portion 3 b of the base 3.

また、結合具として丁番５を用いずに、図７に示すように、基台３の表面３ａに磁石からなる凸部３ｆを、また、枠体４の裏面４ｄに前記凸部３ｆに対応して磁石に吸着する素材からなる凹部４ｆをそれぞれ設け、凸部３ｆと凹部４ｆを嵌合させて凸部３ｆの磁力によって基台３と枠体４を結合させてもよい。この場合、基台３と枠体４を結合する結合具である凸部３ｆ及び凹部４ｆがイヤリング１の外面に表れず、美しい納まりとなり、好ましい。 Further, as shown in FIG. 7, without using the hinge 5 as a coupling tool, the convex portion 3f made of a magnet corresponds to the front surface 3a of the base 3, and the rear surface 4d of the frame body 4 corresponds to the convex portion 3f. Then, the recesses 4f made of a material that is attracted to the magnet may be provided, the protrusions 3f and the recesses 4f may be fitted, and the base 3 and the frame body 4 may be coupled by the magnetic force of the protrusions 3f. In this case, the convex part 3f and the concave part 4f which are coupling tools which couple | bond the base 3 and the frame 4 do not appear on the outer surface of the earring 1, but it becomes a beautiful accommodation and is preferable.

また、耳止具６は、枠体４に固定されたバネ筒６ａにより付勢されて基台３とにより耳たぶＥを挟むことによってイヤリング１を耳たぶＥに挟止する、所謂クリップ式のものを説明したが、耳止具６は、基台３に固定されていてもよく、また、イヤリング１を耳たぶＥに挟止する機能を奏する構造のものであれば、例えば、バネ筒６ａを備えず、耳止具６の一端を枠体４に固定して、耳止具６の他端側に所謂ネジ式の締着部材を備えたものであって、該締着部材が基台３方向に螺挿されて該締着部材と基台３の裏面３ｃにより耳たぶＥを挟むことによってイヤリング１を耳たぶＥに挟止するものとしてもよい。また、イヤリング１は、図８に示すように、耳止具６のみで耳たぶＥに挟止するようにし、該耳止具６を基台３又は枠体４に鎖８等で繋ぐように設けて、耳たぶＥの下方に装飾プレート２、基台３、枠体４等が吊られるものとしてもよい。 Further, the ear stopper 6 is a so-called clip type that is urged by a spring cylinder 6 a fixed to the frame body 4 and clamps the earring 1 to the earlobe E by sandwiching the earlobe E with the base 3. As described above, the ear fastener 6 may be fixed to the base 3, and if it has a structure that functions to clamp the earring 1 to the earlobe E, for example, it does not include the spring cylinder 6a. One end of the ear fastener 6 is fixed to the frame 4 and a so-called screw-type fastening member is provided on the other end side of the ear fastener 6, and the fastening member extends in the direction of the base 3. The earring 1 may be clamped to the earlobe E by being screwed and sandwiching the earlobe E between the fastening member and the back surface 3 c of the base 3. Further, as shown in FIG. 8, the earring 1 is provided so as to be clamped to the earlobe E only by the ear fastener 6 and to be connected to the base 3 or the frame body 4 by the chain 8 or the like. The decoration plate 2, the base 3, the frame body 4 and the like may be suspended below the earlobe E.
