靴の光装着具Light fitting for shoes

　本発明は、歩行や走行動作で無電源で起電して光り、その起電した電気で靴の周りに発光させて視覚させる靴の光装着具に関する。 The present invention relates to a light fitting for shoes that causes a light to rise and glow with no power supply in walking and running operations, and causes the light around the shoes to emit light for visual recognition.

　従来、靴に発光装置を設けて靴の周りに発光させて存在を視覚させる靴の提案は幾つもされている。例えば靴内に電源となる電池を設け、その電池で供給される電気でＬＥＤ等を光らせる靴として、特開２００５－１３３１４号公報、登録実用新案３０３８４６８号、登録実用新案３０４７４７３号、特開平８－３３２１０号公報、特開平１１－３２８１３号公報等が提案されてる。しかしそれらに共通する問題として、靴内に電池を内蔵する発光装置を組み込み製作するのは非常に困難で、その実現には例えば発光装置を靴内に組み込んで収容スペースの問題、製作上かなりコスト高になる問題、靴を洗濯できない問題、電池が切れたら発光しなくなるため電池を交換しなければならない問題等があり、さらに靴を発光させるには必ずその発光装置を内蔵した靴を履かなければならないし、靴が消耗した場合には、発光させるにはまた同じ靴を買わなければならない。また構造上の問題として、従来の発光靴の構造では一方方向にしか光らせられない問題もあった。 Heretofore, a number of proposals have been made for shoes that are provided with a light emitting device so that light is emitted around the shoes to make the presence visible. For example, as a shoe in which a battery serving as a power source is provided in the shoe and the LED and the like are illuminated by electricity supplied by the battery, Japanese Patent Application Laid-Open No. 2005-13314, Registered Utility Model 3038468, Registered Utility Model 3047473, Japanese Patent Application Laid-Open No. 8- Japanese Patent Publication No. 33210, Japanese Patent Publication No. 11-32813, etc. have been proposed. However, as a problem common to them, it is very difficult to incorporate and manufacture a light emitting device incorporating a battery in a shoe, and for that purpose, for example, the light emitting device is incorporated in a shoe and the problem of storage space, considerable cost in manufacturing There is a problem that becomes high, a problem that you can not wash shoes, a problem that you have to replace the battery because it does not emit light when the battery is exhausted, etc. If you wear your shoes, you have to buy the same shoes again to make them glow. Further, as a structural problem, there is also a problem that the light emitting shoe of the prior art can only be lighted in one direction.

　また靴内に圧電素子を設け、圧電素子で起電させて光らせる靴として、特願２０００－０２２０６１号公報、特開平８－１６８２７２号公報、特開公表平５－５０４２８３号公報、特開平６－２０９８０７号公報、特開２００１－３０８４０５号公報、特開２００５－１８３２７５号公報、特開２００６－１０７８５９号公報等が提案されており、それらの各構成、起電方法、問題点を表１にまとめている。それらの共通する問題として、やはりどの構成も靴内に圧電素子と発光体の発光装置を設ける構成であるため、いずれも製作が非常に難しく、また同様にその構造ではその発光体が靴の外に発光する方向は、一方方向（靴の底で後方、側方、前方のいずれか）に固定されて発光することになる。 Further, as a shoe in which a piezoelectric element is provided in the shoe and generated by the piezoelectric element to emit light, Japanese Patent Application No. 2000-022621, Japanese Patent Application Laid-Open No. 8-168272, Japanese Patent Application Laid-Open No. 5-504283, Japanese Patent Application Laid-Open No. 6- No. 209807, JP-A 2001-308405, JP-A 2005-183275, JP-A 2006-107859, etc. are proposed, and their respective configurations, generation methods and problems are summarized in Table 1. ing. As a problem common to them, since all configurations are also configured to provide the light emitting devices of the piezoelectric element and the light emitter in the shoe, it is very difficult to manufacture either, and in the structure as well, the light emitter is outside the shoe. The direction of light emission is fixed in one direction (back, side, or front at the bottom of the shoe) to emit light.

　本発明は、前述した従来の問題に鑑みて発明したもので、歩いたり走ったりする動作で無電源で起電できて発光でき、既存する靴を何ら加工することなく、その靴の狭いスペース内に起電部を設けて、如何なる靴にも着脱可能に装着でき、その起電した電気で発光する可視光の光を靴の外方向へ、靴の側方から後方の間の所望方向に設定して装着でき、従来に無い「靴の光装着具」を提供することである。 The present invention was invented in view of the above-mentioned conventional problems, and it is possible to generate and emit light without a power supply by walking and running, and within the narrow space of the shoe without processing any existing shoes. Can be detachably attached to any shoe, and the visible light emitted by the electricity generated by the electricity is set in the desired direction between the side of the shoe and the rear of the shoe. It is an object of the present invention to provide a "light fitting for shoes" which can be worn out and is not available in the prior art.

　本発明は、前記課題を解決するために、歩いたり走ったりする動作で足を踏み下ろす圧力が加わると、その圧力によって起電する起電部を靴内の狭いスペースに起電部を設けられるように平板状に形成し、その平板状の起電部上に前記足を踏み下ろす圧力が加わることで、その圧力に追従して圧電体が歪んで起電でき、その起電部によって起電する電気を靴の外側へと給電する配線材を設けて、その配線材にＬＥＤを接続して発光するようにし、その給電する配線材を固定具によって靴の所望する開口部分や部位に固定させることで、着脱可能に装着できるようにした構成である。 According to the present invention, in order to solve the above-mentioned problems, when a pressure for stepping on the foot is applied by walking or running, the electromotive unit can be provided in a narrow space in the shoe when the pressure is applied. When a pressure is applied to step down the foot on the flat plate-like electromotive portion, the piezoelectric body can be distorted to generate electricity following the pressure, and the electromotive portion A wiring material for supplying electricity to the outside of the shoe is provided, and the LED is connected to the wiring material to emit light, and the wiring material to be supplied with electricity is fixed to a desired opening portion or part of the shoe by a fixture. Is configured to be detachably mounted.

　その平板状の起電部を構成するのに、その起電部は圧電起電部を可撓性のある平板状の基板面に平薄状の圧電体を設けた構成で実施でき、その平板状の基板面上に前記圧力が加わってその基板が撓んで変形することで、その変形に追従して平薄状の圧電体も歪んで起電できる構成である。 In order to constitute the flat-plate-like electromotive part, the flat-plate-like piezoelectric body may be provided on the flexible flat-plate substrate surface of the piezoelectric electromotive part, and the flat-plate-like piezoelectric member can be embodied. The pressure is applied to the substrate surface of the plate shape to bend and deform the substrate, whereby the flat thin piezoelectric material can also be distorted and generated following the deformation.

　本発明は、歩行や走行の運動のエネルギーを電気エネルギーに変換して発光できるため、電池が不要であり、靴を履き替えてもいつまでも無電源で半永久的に使用できる。 The present invention can convert the energy of walking or running exercise into electric energy and emit light, so no battery is required, and it can be used semi-permanently with no power supply even if the shoes are changed.

　本発明の靴の光装着具は、どんな狭い靴内でも靴底上に起電部を載置して起電でき、そして如何なる既存の靴でも何ら加工することなく、固定具により靴に着脱可能に固定して装着でき実施できる。そして本発明の靴の光装着具は、装着する人の所望する靴の部位に装着できるため、その装着する部位でＬＥＤの照射方向を側方から後方の間で任意に設定でき、視覚させたい方向を側方から後方の間の範囲にいる人に発光させて視覚させることができる。特に本発明を４５°斜め後方に向けて装着すれば、靴の側方と後方にいる全て人を同時に視覚させることができる。そして靴を履き替えてもいつまでも無電源で半永久的に使用できる。また本発明の起電部は、嵩張らずに上からの圧力や衝撃に対して、その力の大きさに比例して適当に撓むことができるため、その力を吸収して衝撃を和らげるクッションの役目を果たす効果を既存の靴に装着して同時にもたらすことができる The light fitting of the shoe of the present invention can be produced by placing the electromotive section on the sole of the shoe in any narrow shoe, and can be detached from the shoe by means of fasteners without processing any existing shoes It can be fixed and mounted. And since the light mounting tool of the shoe of the present invention can be worn on the portion of the shoe desired by the person wearing it, the illumination direction of the LED can be arbitrarily set from the side to the rear at the portion to be worn. The direction can be made to light and be visible to the person in the range between the side and the back. In particular, if the present invention is worn 45 degrees diagonally backward, it is possible to simultaneously view all persons on the side and the rear of the shoe. And even if you change your shoes, you can use it permanently with no power forever. In addition, since the electromotive unit of the present invention can be appropriately bent in proportion to the magnitude of the pressure or impact from above without being bulky, a cushion that absorbs the force and cushions the impact. Can be attached to the existing shoes at the same time

　本発明の実施例の構成を図面を元に詳細に説明する。図１、図２は本発明の「靴の光装着具」の実施例の全体図を示し、図３は本発明の「靴の光装着具」の起電部の実施例の構成を示すものである。 The configuration of an embodiment of the present invention will be described in detail based on the drawings. 1 and 2 show the overall view of the embodiment of the "light fitting for shoes" of the present invention, and Fig. 3 shows the configuration of the embodiment of the electromotive unit of the "light fitting for shoes" of the present invention. It is.

　図１において、起電部２の外形を略円状で平板状に形成し、その起電部２で起電する電気を給電する配線材３を接続して具備し、その配線材３として靴内から靴の外側へと給電する平行２芯ケーブルを約１０ｃｍの長さに形成し、その配線材３を靴の所望の位置に固定する固定具４としてクリップ４ａを設け、そのクリップ４ａの内側に溝４ｄを形成して、その溝４ｄに配線材３を嵌合して設け、その配線材３の先端に露呈した芯線に、ＬＥＤ６の各端子をそれぞれはんだ付け等で接続する。固定具４としてクリップ４ａを適当に可撓する樹脂材でＵ字状に形成し、そのＵ字状に形成したクリップ４ａの内側に前記溝部４ｄと開口する開口部４ｅを形成し、その開口部４ｅからＬＥＤ６を嵌合して外側に突出させている。図１（ｂ）はクリップ４ａが通常の負荷をかけてない状態を示し、そのクリップ４ａは可撓性があるため、矢印の方向へ撓ませて図１（ｃ）の状態にすると、クリップ４ａは図１（ｂ）の元の形状に戻ろうとして、常に内側へと力が加わる状態になる。そのため靴の開口の淵にクリップ４ａで挟むことで、その可撓性の性質で固定できる。 In FIG. 1, the outer shape of the electromotive portion 2 is formed in a substantially circular and flat plate shape, and a wiring member 3 for feeding electricity generated by the electromotive portion 2 is connected and included. A parallel two-core cable for feeding power from the inside to the outside of the shoe is formed to a length of about 10 cm, and a clip 4a is provided as a fixture 4 for fixing the wiring member 3 at a desired position of the shoe. The grooves 4d are formed, and the wiring members 3 are fitted and provided in the grooves 4d, and the terminals of the LEDs 6 are respectively connected to the core wires exposed at the ends of the wiring members 3 by soldering or the like. The clip 4a is formed in a U-shape with a resin material that appropriately flexes as the fixing tool 4, and an opening 4e that opens with the groove 4d is formed inside the U-shaped clip 4a, and the opening is The LED 6 is fitted from 4e and projected outward. FIG. 1 (b) shows a state in which the clip 4a is not loaded normally, and since the clip 4a is flexible, the clip 4a is bent in the direction of the arrow to be in the state of FIG. 1 (c). In order to return to the original shape of FIG. 1 (b), a force is always applied inward. Therefore, by holding the clip 4a at the edge of the opening of the shoe, it can be fixed by its flexible nature.

　図４は、図１に示した本発明の「靴の光装着具」の実施例の構成を実際に既存の靴へ、固定具４のクリップ４ａで挟んで装着した状態を示したものである。図のようにクリップ４ａを靴の開口の淵に挟ませれば、前記したクリップ４ａの可撓性によって、その淵上にしっかり固定でき図４（ｂ）の状態にして固定できる。 FIG. 4 shows a state in which the configuration of the embodiment of the “light fitting for shoes” of the present invention shown in FIG. 1 is actually attached to an existing shoe with the clip 4a of the fixing tool 4 interposed. . If the clip 4a is pinched in the heel of the opening of the shoe as shown, the flexibility of the clip 4a allows the clip 4a to be firmly fixed on the heel and in the state of FIG. 4 (b).

　図５は、図１に示した本発明の「靴の光装着具」を靴に装着した状態の縦断面図を示す。図５（ａ）に示すように、本発明の「靴の光装着具」を構成する起電部２は平薄で平板状であり、靴内の狭いスペースの靴底上に載置して装備することができ、実際に靴を履いて歩いても邪魔にならないし違和感が無い。そして図５（ｂ）の靴を履いた状態になると、踵が起電部２上に載った状態で歩いたり走ったりする度に、平板状の起電部２上に体の荷重が加わることになり、その荷重で起電部２を構成する圧電起電部２Ａの圧電体２ｂには、その圧力で歪みの変形が起き、その歪みの変形によって圧電体２ｂから起電流を発生する。その実際の起電原理については図７で後述する。尚、図１の構成において、クリップ４ａはアルミ等の金属板で形成してもよいし、また図１（ｅ）で示すように開口部４ｅを縦長に形成し、その開口部４ｅ内でＬＥＤ６を上下（↑↓）方向に適当に位置をずらして固定するようにしてもよい。また開口した開口部４ｅを縦にそれぞれ幾つか設けておき、そのひとつの開口部４ｅからＬＥＤ６を突出して固定するように構成してもよい。 FIG. 5 is a longitudinal cross-sectional view of the “light fitting for shoes” of the present invention shown in FIG. 1 attached to the shoe. As shown in FIG. 5A, the electromotive unit 2 constituting the “light fitting for shoes” of the present invention is flat and thin and flat, and is placed on the sole of a narrow space in the shoe. It can be equipped, and it will not get in the way even if you actually walk with shoes and there is no discomfort. Then, when the shoes shown in FIG. 5 (b) are worn, the weight of the body is applied on the plate-like electromotive unit 2 every time the user walks or runs while the heel is on the electromotive unit 2. Due to the load, deformation of strain occurs in the piezoelectric body 2b of the piezoelectric electromotive portion 2A that constitutes the electromotive portion 2, and an electromotive current is generated from the piezoelectric body 2b due to the deformation of the strain. The actual electromotive principle will be described later with reference to FIG. In the configuration of FIG. 1, the clip 4a may be formed of a metal plate such as aluminum, or the opening 4e is vertically elongated as shown in FIG. 1 (e), and the LED 6 is formed in the opening 4e. May be fixed by shifting the position appropriately in the vertical direction (↑). Further, it is also possible to provide several openings 4e which are open vertically and to project and fix the LED 6 from the one opening 4e.

　次に本発明の「靴の光装着具」の装着について、図４（ｃ）に示すように、靴の開口した淵の側方から後方の間（ＸとＺの間）の所望の位置に、クリップ４ａを挟んで固定することができる。そのためその固定する位置によって、側方（Ｘ方向）から後方（Ｚ方向）の間のどの方向にもＬＥＤ６を向けて発光させられ、その方向に照射することができる。またＬＥＤ６を斜め４５°後方（Ｙ方向）に向けて固定でき、そのＬＥＤ６の発光方向によって、側方と後方の人に対し同時に視覚させることができるため、その視覚範囲が非常に広がる。尚、図４（ｃ）の実施構成においては、起電部２を靴の底面上に貼って固定し、配線材３を予め長めにしておくことで、図５（ｂ）に示す様に踵の後ろと靴内の後端部域の空いたスペース内に、その長めの余った配線材３を沿わすことで、固定具４の固定位置を所望の位置で設定して装着できるようにして実施してもよい。 Next, as shown in FIG. 4 (c), with respect to the mounting of the “light fitting for shoes” of the present invention, at a desired position between the side and the rear of the open heel of the shoe (between X and Z). , Clip 4a can be fixed. Therefore, the LED 6 can be made to emit light in any direction between the side (X direction) and the rear (Z direction) depending on the fixed position, and the LED 6 can be irradiated in that direction. Further, the LED 6 can be fixed obliquely 45 ° backward (in the Y direction), and the light emission direction of the LED 6 can be made visible simultaneously to persons on the side and the rear, so the visual range is greatly expanded. In the embodiment shown in FIG. 4 (c), the electromotive unit 2 is stuck and fixed on the bottom of the shoe, and the wiring member 3 is made longer beforehand, as shown in FIG. 5 (b). By setting the fixed position of the fixing tool 4 at a desired position so that it can be mounted by following the extra surplus wiring member 3 in the vacant space of the back of the shoe and the rear end region in the shoe You may implement.

It is the structure equipped with the material 4b. As the fastening material 4b, for example, an adhesive material may be applied, the release paper may be peeled off from the surface of the bonding material, and the fastening material 4b may be adhered to a desired position of the shoe. Also, as shown in FIG. 2 (b), the

fastening materials

4b, 4b to be fastened to each other are provided, and as shown in FIG. 6, one fastening material 4b is suitably placed in the desired position of the shoe. It may be applied in size, and the other fastening materials 4b may be engaged with the fastening materials 4b. With this configuration, the position at which the fixing member 4b is fixed can be changed somewhat depending on the size of one of the fixing members 4b, and the light emitting position of the LED 6 can be appropriately changed and fixed. Here, as the

fastening materials

As the tape material 4c, for example, a vinyl tape, a cloth adhesive tape, an aluminum foil tape or the like can be used. As another example, the fixing tool 4 may be configured with an adhesive applied in advance on the surface of the wiring member 3.

　図３は、本発明の「靴の光装着具」を構成する起電部２において、その構成の各実施例を示すものである。「靴の光装着具」を構成する起電部２は、その起電する平板状の構成として圧電起電部２Ａでなり、その圧電起電部２Ａは図８に示す構成で実施するものであり、その圧電起電部２Ａの構成について、次に詳述する。本発明を構成する圧電起電部２Ａは、適当な厚みで可撓性があり好ましくは金属板でなる平板状の基板２ａで構成し、その基板２ａの面上に設けた適当な大きさと厚みでなる平薄状の圧電体２ｂと、その圧電体２ｂの上面に電極面２ｃを設けて構成する構造である。一般に圧電セラミックの圧電体は、弾性が無く強い衝撃や曲げによって割れてしまうが、その圧電セラミックを平薄状に形成することで、その平薄状にした圧電セラミックには、ある程度弾性が出てある程度割れずに曲げることができる。そのため図８に示す構造にして、平板状で可撓性のある金属板でなる基板２ａ上に、圧電セラミックでなる圧電体２ｂを平薄状に設けることで、その圧電体２ｂが割れない範囲内で撓ませて起電させることができる。そのため本発明を構成する圧電起電部２Ａは、可撓性がある基板２ａと、その面上に平薄状に設けた圧電体２ｂによって構成することで、適当に撓んで割れずに曲げられ、その構造は非常に平薄状に構成できて嵩張らずに上からの圧力や衝撃に対して、その力の大きさに比例して適当に撓むことができ、その力を吸収して衝撃を和らげるクッションの役目を果たすことができるため、靴内に設けても違和感が無く実施できる。本発明の実施例として、圧電起電部２Ａを構成する基板２ａは、適当な厚みで可撓性がある金属等で構成でき、実施例としては黄銅、アルミ、銅や、合金でなる４２ALLOY等で実施できる。また基板２ａを薄いプラスチック材でその面上にアルミ蒸着して形成したり、導電性のカーボン等を成膜して構成してもよい。また基板２ａ全体を導電ゴムや導電性プラスチック材で形成して構成してもよい。基板２ａの厚みとしては、適当に撓んで可撓性を持つ厚さであればよく、金属板で形成した場合は実施例として、その金属の材質にもよるが、例として２～１ｍｍ以下から０.５～０.３ｍｍ以下で０.２ｍｍ以下であればさらによい。圧電体２ｂは、圧電セラミックとしては、チタン酸ジルコン酸鉛（PZT）の他に、チタン酸バリウム（BaTiO₃）、チタン酸鉛、ニオブ酸鉛、ニオブ酸リチウム等を焼結して分極処理したもので構成でき、実施例として０.２～０.０６ｍｍの厚みで実施できる。また圧電フィルムとしては、フィルム状のポリフッ化ビニリデン（PVDF）等で構成して実施できる。いずれの物質も圧力を加えることで、物質内に電気分極が生じて起電流を発生する。 FIG. 3 shows each example of the configuration of the electromotive unit 2 constituting the “light fitting for shoes” of the present invention. The electromotive unit 2 constituting the "light fitting for shoes" is a piezoelectric electromotive unit 2A as a flat plate-like configuration that generates electricity, and the piezoelectric electromotive unit 2A is implemented by the configuration shown in FIG. The configuration of the piezoelectric electromotive portion 2A will now be described in detail. The piezoelectric electromotive part 2A constituting the present invention is constituted by a flat substrate 2a of a suitable thickness and flexibility and preferably made of a metal plate, and the appropriate size and thickness provided on the surface of the substrate 2a And the electrode surface 2c provided on the upper surface of the piezoelectric body 2b. Generally, a piezoelectric ceramic piezoelectric body is not elastic and is broken by a strong impact or bending, but by forming the piezoelectric ceramic in a flat thin shape, the flat thin piezoelectric ceramic has elasticity to some extent. It can be bent without cracking to some extent. Therefore, by providing the piezoelectric body 2b made of piezoelectric ceramic in a flat thin shape on the substrate 2a made of a flat and flexible metal plate in the structure shown in FIG. 8, the range in which the piezoelectric body 2b is not broken It can be bent inside to generate electricity. Therefore, the piezoelectric electromotive portion 2A constituting the present invention is appropriately bent without being broken by being constituted by the flexible substrate 2a and the piezoelectric member 2b provided flatly on the surface thereof. The structure can be very flat and thin, and can be suitably bent in proportion to the magnitude of the force against pressure and impact from above without being bulky, and the force absorbed is the impact Since it can serve as a cushion for relieving pain, it can be implemented without discomfort even if it is provided in the shoe. As an embodiment of the present invention, the substrate 2a constituting the piezoelectric electromotive portion 2A can be made of a metal or the like having a suitable thickness and flexibility, and as an embodiment, 42 ALLOY or the like made of brass, aluminum, copper, or an alloy Can be implemented by Alternatively, the substrate 2a may be formed by vapor deposition of aluminum on the surface of a thin plastic material, or conductive carbon or the like may be formed into a film. Further, the entire substrate 2a may be formed of conductive rubber or a conductive plastic material. The thickness of the substrate 2a may be a thickness that can be appropriately bent and has flexibility, and when it is formed of a metal plate, although depending on the material of the metal as an example, it is from 2 to 1 mm or less as an example It is even more preferable if it is 0.5 to 0.3 mm or less and 0.2 mm or less. The piezoelectric body 2b is obtained by sintering and polarizing barium titanate (BaTiO ₃ ), lead titanate, lead niobate, lithium niobate, etc. in addition to lead zirconate titanate (PZT) as a piezoelectric ceramic. The embodiment can be implemented with a thickness of 0.2 to 0.06 mm as an example. The piezoelectric film can be implemented by using film-like polyvinylidene fluoride (PVDF) or the like. By applying pressure to any substance, an electric polarization occurs in the substance to generate an electromotive current.

　図３で本発明の「靴の光装着具」を構成する起電部２の各実施例を順に説明する。図３（ａ）は、起電部２が圧電起電部２Ａだけでなる構成である。圧電起電部２Ａの構造は前述した通りで、配線材３の先端に露出した各芯線を基板２ａと可撓性を持つ電極板２Ｂの面に、それぞれはんだ付け等で接続しており、その接続した電極板２Ｂの面と圧電体２ｂの電極面２ｃを互いに接面させて構成したものである。この図３（ａ）の構成で、図５に示すように靴底上に載置して設けても、靴底には元々若干弾性があるため、基板２ａと電極板２Ｂはその可撓性によって、踵から受ける荷重を吸収して適当に撓む変形が起き、その撓む変形に追従して圧電体２ｂも適当に撓む歪みが起きて起電でき、本発明をこの構成によって実施できる。尚、前記電極板２Ｂに配線材３の一方の芯線をはんだ付け等で接続する替わりに、圧電体２ｂの電極面２ｃに直接配線材３の一方の芯線をはんだ付け等で接続して構成してもよいし、同様に実施可能である。図３（ｂ）は、図３（ａ）で示した構成にさらに弾性がある上敷き２Ｄを重ねて設けて構成するものである。この構成であれば弾性がある上敷き２Ｄによって、さらに踵から受ける荷重を吸収できるため、実際に靴内に載置して履いた状態でも、違和感無く実施できる。図３（ｃ）は、図３（ｂ）で示した構成にさらに弾性のある下敷き２Ｅを下に重ねて、その下敷き２Ｅ上に電極板２Ｂを配線材３の一方の芯線をはんだ付け等で接続し構成したものである。この構成であれば弾性のある上敷き２Ｄと下敷き２Ｅによって、さらにもっと踵に加わる荷重を吸収できるため、実際に靴を履いてても全く違和感が無くさらに心地感も得られる。弾性のある上敷き２Ｄ及び下敷き２Ｅとしては、ゴム材や発泡プラスチック等で実施でき、その厚みも例えば０.５～２ｍｍ程度に実施できる。尚、図３（ｂ）で示した構成において、上敷き２Ｄを設ける替わりに、下敷き２Ｅのみ基板２ａの下に設けて構成して実施してもよい。図３（ｄ）は、上敷き２Ｄと下敷き２Ｅを導電性ゴムで構成して実施するものである。導電性ゴムは弾性と導電性があるため、その導電性ゴムでなる上敷き２Ｄと下敷き２Ｅに配線材３の各芯線を接続し、その上敷き２Ｄと下敷き２Ｅによって圧電起電部２Ａをサンドイッチ状態に挟んで構成することで、下敷き２Ｅの上面と基板２ａの下面が接面して導通状態になり、同様に上敷き２Ｄの下面と圧電体２ｂの電極面２ｃとが接面して導通状態になり、その上敷き２Ｄと下敷き２Ｅから直接通電できて実施できるため、はんだ付け等の工程が無くなり製作が非常に簡単にできる。尚、この構成で上敷き２Ｄと下敷き２Ｅとを互いに絶縁状態にするため、それより若干大きめの紙等でなるドーナツ形状の絶縁材２Ｃで、図のように介在させて設けている。この絶縁材２Ｃによって、その中央に開口した部分から上敷き２Ｄの下面と、電極面２ｃのみが電気的に導通状態に接面することになる。尚、各起電部２の構成で、各圧電起電部２Ａを上下逆さまにして、圧電体２ｂと電極面２ｃが下向きで、その上に基板２ａが上向きになるように、図３（ａ）～（ｄ）で示す各起電部２の構成を上下反転して構成して実施してもよい。また本発明を構成する起電部２の外形の形状も、実施例で示した略円形に限らず角形状でも良いし、中敷き（インソール）大の大きさに形成して実施してもよい。また靴内に載置して設ける起電部２の位置も、踵が当接する位置に限らず土踏まずからつま先の間で当接するように載置して設けても良い。また本発明は、サンダルやスリッパにも装着できるため、本発明の「靴の光装着具」はサンダルやスリッパ等も対象に含まれる。 Each Example of the electromotive part 2 which comprises "the optical mounting tool of shoes" of this invention with FIG. 3 is described in order. FIG. 3A shows a configuration in which the electromotive unit 2 includes only the piezoelectric electromotive unit 2A. The structure of the piezoelectric electromotive portion 2A is as described above, and each core wire exposed at the tip of the wiring member 3 is connected to the surface of the substrate 2a and the flexible electrode plate 2B by soldering or the like. The surface of the connected electrode plate 2B and the electrode surface 2c of the piezoelectric body 2b are configured to be in contact with each other. In the configuration of FIG. 3 (a), even if it is placed on the sole as shown in FIG. 5, since the sole has some elasticity originally, the substrate 2a and the electrode plate 2B are flexible. Can absorb the load received from the crucible and deform appropriately, and the piezoelectric body 2b can be appropriately distorted to follow the bending deformation to generate electricity, and the present invention can be practiced with this configuration . Incidentally, instead of connecting one core wire of the wiring member 3 to the electrode plate 2B by soldering or the like, one core wire of the wiring member 3 is directly connected to the electrode surface 2c of the piezoelectric body 2b by soldering. It may be implemented as well. FIG. 3 (b) is configured by superposing an elastic overlay 2D on the configuration shown in FIG. 3 (a). With this configuration, the load received from the heel can be further absorbed by the elastic overlay 2D, so that even in a state of being actually placed and worn in a shoe, it can be implemented without discomfort. In FIG. 3 (c), an elastic underlayment 2E is further superimposed below the configuration shown in FIG. 3 (b), and the electrode plate 2B is soldered onto the underlayment 2E. It is connected and configured. With this configuration, the load applied to the heel can be absorbed further by the elastic upper sheet 2D and the lower sheet 2E. Therefore, even when the user actually wears a shoe, there is no sense of incongruity, and a more comfortable feeling can be obtained. The elastic overlays 2D and underlays 2E can be made of rubber, foamed plastic or the like, and the thickness thereof can be, for example, about 0.5 to 2 mm. In the configuration shown in FIG. 3B, instead of providing the overlay 2D, only the underlay 2E may be provided below the substrate 2a. In FIG. 3D, the upper sheet 2D and the lower sheet 2E are formed of conductive rubber. Since the conductive rubber has elasticity and conductivity, the respective core wires of the wiring material 3 are connected to the upper sheet 2D and the lower sheet 2E made of the conductive rubber, and the piezoelectric electromotive portion 2A is sandwiched by the upper sheet 2D and the lower sheet 2E. By sandwiching, the upper surface of the underlayment 2E and the lower surface of the substrate 2a are in contact with each other to be in the conductive state, and similarly the lower surface of the overlay 2D and the electrode surface 2c of the piezoelectric body 2b are in contact and in the conductive state. Since it is possible to conduct electricity directly from the upper sheet 2D and the lower sheet 2E, the process such as soldering can be eliminated and the manufacture can be extremely simplified. In addition, in order to make the upper sheet 2D and the lower sheet 2E mutually insulated with this configuration, a doughnut-shaped insulating material 2C made of a paper slightly larger than that is provided as shown in the figure. By the insulating material 2C, only the lower surface of the overlay 2D and the electrode surface 2c come into electrical conduction from the portion opened at the center thereof. In the configuration of each electromotive unit 2, each piezoelectric electromotive unit 2A is turned upside down so that the piezoelectric body 2b and the electrode surface 2c are directed downward and the substrate 2a is directed upward, as shown in FIG. The configuration of each of the electromotive units 2 shown in FIGS. Further, the outer shape of the electromotive unit 2 constituting the present invention is not limited to the substantially circular shape shown in the embodiment but may be a square shape, or may be formed with a large insole size. Further, the position of the electromotive unit 2 provided in the shoe is not limited to the position where the heel abuts, and may be provided so as to abut between the arch and the toes. Further, since the present invention can also be mounted on sandals and slippers, the "light fitting for shoes" of the present invention also includes sandals, slippers, and the like.

　図７は、本発明の起電原理を示すものである。図７（ａ）は圧電起電部２Ａで起電する原理を示し、図７（ｂ）～（ｅ）は図３（ｄ）に示した起電部２によって起電する原理を示すものである。図７（ａ）において、基板２ａ上に設けた圧電体２ｂに下方向の矢印で示す圧力を加えると、その圧電体２ｂに撓みの歪みが起きると同時に、圧電体２ｂが起電流ｉ（←）を発生してＬＥＤ６ａを発光させる。次にその歪ませた圧力を取り去ると、基板２ａが持つその可撓性の性質によって元の形状に戻り、そしてそれに追従して圧電体２ｂも元の形状に戻り、同時にその際起電流ｉ（→）を発生してＬＥＤ６ｂを発光させる。この起電原理によって、図５（ｂ）に示すように靴を履いて歩いたり走ったりすると、図７（ｂ）（ｃ）に示すように、足を下ろすごとに踵から受ける体重（荷重）によって、圧電起電部２Ａにはその体重による下方向の矢印で示す荷重が加わり、基板２ａ及び圧電体２ｂには若干外側に撓む歪みが起き、その歪みの変形によって、圧電体２ｂが起電して起電流ｉ（←）を発生する。そしてその起電流ｉ（←）によって、ＬＥＤ６ａが点灯して発光する。次に図７（ｄ）（ｅ）に示すように、地面に一旦下ろした足を上に持ち上げると、それまで踵から加わってた荷重が無くなり、同時に基板２ａに加わってた圧力も無くなるため、その可撓性のある基板２ａは自力で元の形状に戻り、その基板２ａに追従して圧電体２ｂも元の形状に戻り、起電流ｉ（→）を起電してＬＥＤ６ｂが点灯し発光する。このため足を下ろして上げる動作の間に２回起電が起き、その起電ごとにＬＥＤ６ａとＬＥＤ６ｂが交互に点灯して発光する。そのため例えばＬＥＤ６ａを赤いＬＥＤで構成して、ＬＥＤ６ｂを緑色のＬＥＤで構成すると、交互に光る２色の発光によって周りの人に視覚させられ、かなりの注意喚起の効果が出る。また例えば固定具４を２つ用意しておき、図４（ｃ）の状態でひとつの各固定具４でＬＥＤ６ａをＺ方向に向けて固定し、もうひとつの固定具４でＬＥＤ６ｂをＸ方向に向けて固定すれば、ひとつの起電部２で、後方にも側方にも同時に発光させて、周りの人に視覚させることができる。 FIG. 7 shows the electromotive principle of the present invention. FIG. 7 (a) shows the principle of generation of electricity by the piezoelectric electromotive part 2A, and FIGS. 7 (b) to 7 (e) show the principle of generation of electricity by the electromotive part 2 shown in FIG. 3 (d). is there. In FIG. 7A, when a pressure indicated by a downward arrow is applied to the piezoelectric body 2b provided on the substrate 2a, distortion of bending occurs in the piezoelectric body 2b, and at the same time, the piezoelectric body 2b generates an electromotive force i (← ) To cause the LED 6a to emit light. Next, when the distorted pressure is removed, the flexible property of the substrate 2a returns to the original shape, and following it, the piezoelectric member 2b also returns to the original shape, and at the same time the electromotive current i →) is generated to make the LED 6 b emit light. By this principle of electromotive force, as shown in FIG. 5 (b), when walking or running in shoes, as shown in FIG. 7 (b) (c), weight (load) received from heels every time the foot is lowered As a result, a load shown by the downward arrow due to the weight is applied to the piezoelectric electromotive part 2A, and a distortion occurs in which the substrate 2a and the piezoelectric body 2b are slightly bent outward, and the deformation of the distortion causes the piezoelectric body 2b to rise. Generate an electromotive current i (←). Then, the LED 6a is lit and emits light due to the electromotive current i (←). Next, as shown in FIGS. 7 (d) and 7 (e), lifting the foot once lowered to the ground eliminates the load applied from the heel and removes the pressure applied to the substrate 2a. The flexible substrate 2a returns to its original shape by its own force, and the piezoelectric body 2b returns to its original shape following the substrate 2a, and the electromotive current i (→) is generated to turn on the LED 6b to emit light. Do. For this reason, during the operation of lowering and raising the foot, a voltage rise occurs twice, and the LED 6a and the LED 6b alternately light and emit light each time the voltage rises. Therefore, if, for example, the LED 6a is formed of a red LED and the LED 6b is formed of a green LED, it can be made visible to people around by the bi-colored light emission alternately, and a considerable alerting effect can be obtained. Further, for example, two fixtures 4 are prepared, and the LED 6a is fixed in the Z direction with one fixture 4 in the state of FIG. 4C, and the LED 6b is made in the X direction with another fixture 4. If it fixes facing, it can be made to emit light simultaneously to the back and the side with one electromotive part 2, and it can be made visible to people around.

　図９は、図３で示した起電部２の構成で、足を降ろした時に基板２ａと一体の圧電体２ｂが大きく屈曲し、大きな起電量が得られるようにした構成である。その実施例の図９（ａ）（ｂ）（ｃ）において、基板２ａの下面と下敷き２Ｅの上面との間に、図のように弓形状の挿入板２Ｆを２枚を適当に離して平行に介在させ構成したものである。その構成にして足を踏み降ろせば、図のように基板２ａと下敷き２Ｅとの間に隙間があるため、その隙間分基板２ａが大きく屈曲し、同時に一体の圧電体２ｂも大きく屈曲するため大きな起電量が得られる。もうひとつの実施例の図９（ｄ）（ｅ）（ｆ）は、下敷き２Ｅの下面と靴７の上面との間に、図のように弓形状の挿入板２Ｆを２枚適当に離して平行に介在させて構成するものである。この構成にして足を踏み降ろせば、図のように下敷き２Ｅと靴７との間に隙間があるため、その隙間分下敷き２Ｅとその上に載置した基板２ａが大きく屈曲し、同時に圧電体２ｂも大きく屈曲するため大きな起電量が得られる。ここで介在する挿入板２Ｆの厚みとしては、実施例として０.５ｍｍ～１.０ｍｍ位で実施できる。また図９（ｄ）（ｅ）（ｆ）の構成で、挿入板２Ｆの左右２枚を一体に繋げる図示しない板で連結して構成してもよい。 FIG. 9 shows a configuration of the electromotive unit 2 shown in FIG. 3 in which the piezoelectric body 2b integral with the substrate 2a is largely bent when the foot is lowered to obtain a large amount of electromotive force. In FIGS. 9 (a), (b) and (c) of that embodiment, two arc-shaped insertion plates 2F are appropriately separated and parallel between the lower surface of the substrate 2a and the upper surface of the base 2E as shown. Intervened in the In this configuration, if the foot is stepped down, there is a gap between the substrate 2a and the underlay 2E as shown in the figure, so the substrate 2a is largely bent by the gap and at the same time the integral piezoelectric member 2b is also greatly bent. An electromotive amount is obtained. 9 (d), (e) and (f) of another embodiment, two bow-shaped insertion plates 2F are suitably separated as shown in the figure between the lower surface of the underlayment 2E and the upper surface of the shoe 7. It is configured to be interposed in parallel. In this configuration, when the foot is stepped down, there is a gap between the underlayment 2E and the shoe 7 as shown in the figure, so the underlayment 2E and the substrate 2a placed thereon are largely bent, and at the same time the piezoelectric body Since 2b is also greatly bent, a large electromotive force can be obtained. The thickness of the insertion plate 2F interposed here can be, for example, about 0.5 mm to 1.0 mm. Further, in the configuration of FIGS. 9 (d), (e) and (f), the left and right two sheets of the insertion plate 2F may be connected by a plate (not shown) connecting the two integrally.

　図１０は、図２で示した本発明の「靴の装着具」において、靴への他の装着方法の実施例の構成を示したものである。起電部２で起電した電気を通電する配線材３として、適当に硬くて剛性があり屈曲する金属でなる固定式配線材３Ａで構成したものである。金属の性質として剛性と屈曲性があり、一旦屈曲するとその剛性によってその形を保持する性質がある。そのため前実施例で示した配線材３を固定具４によって靴に装着しなくても、適当に剛性と屈曲性のある金属でなる固定式配線材３Ａを通電する配線材３として構成することで、靴の縁にその固定式配線材３Ａを屈曲させて挟んで固定でき本発明を実施することができる。固定式配線材３Ａによる靴への固定方法としては、予め真直ぐ形状の固定式配線材３Ａを靴の縁に合わせて屈曲して挟んで固定してもよいし、又は予めクリップ形状に屈曲しておいた固定式配線材３Ａを靴の縁に挟んで固定するようにしてもよい。この固定式配線材３Ａは起電部２で起電した電気を通電する役目と、靴の縁に挟んで固定させる２つの役目を果たすことができる。尚、実施例の構成として、通電する配線材３全体を固定式配線材３Ａで構成してもよいし、靴の縁に固定させる部分のみ固定式配線材３Ａで構成してもよい。固定式配線材３Ａを形成する金属材としては、実施例として適当に剛性があって屈曲する鉄材等で実施でき、その形状も図のように短冊状の平薄状が望ましいが、断面が丸い線状でもよい。本実施例の構成では固定式配線材３Ａの先端にコネクタ１０が設けられており、図１１で示すコネクタ１０と抜き差しして実施することができる。 FIG. 10 shows the construction of another embodiment of the method of mounting on a shoe according to the "shoe mounting tool" of the present invention shown in FIG. The wiring member 3 for conducting electricity generated by the electromotive unit 2 is constituted by a fixed wiring member 3A made of a metal which is suitably hard, rigid and bent. The properties of metal are rigidity and flexibility, and once bent it has the property of retaining its shape by its rigidity. Therefore, even if the wiring member 3 shown in the previous embodiment is not attached to the shoe by the fixing tool 4, by configuring the fixed wiring member 3A made of metal having appropriate rigidity and flexibility as the wiring member 3 to be energized The fixed wiring member 3A can be bent and sandwiched and fixed to the edge of the shoe according to the present invention. As a method of fixing to the shoe by the fixed wiring member 3A, the fixed wiring member 3A in a straight shape may be bent in advance in accordance with the edge of the shoe, and may be fixed by being pinched or bent in advance into a clip shape The fixed wiring member 3A may be sandwiched and fixed to the edge of the shoe. The fixed wiring member 3A can play a dual role of conducting electricity generated by the electromotive part 2 and of holding and fixing it on the edge of the shoe. As a configuration of the embodiment, the whole of the wiring member 3 to be energized may be configured by the fixed wiring member 3A, or only a portion fixed to the edge of the shoe may be configured by the fixed wiring member 3A. As a metal material for forming the fixed wiring member 3A, an iron material or the like which is suitably rigid and bent as an example can be used, and the shape is preferably a strip-like flat thin shape as illustrated, but the cross section is round It may be linear. In the configuration of the present embodiment, the connector 10 is provided at the tip of the fixed wiring member 3A, and can be inserted into and removed from the connector 10 shown in FIG.

　図１１は、靴の後面や側面で面状に発光させる本発明の実施例の構成である。アクリル材やシリコン材や塩化ビニル材等の透光性樹脂には導光性の性質があり、樹脂内に入射した光は樹脂内で反射拡散を繰り返し、樹脂内で均一化した光になって樹脂全体を光らせる性質がある。図１１に示す構成は、実際に靴のロゴマークを面状に光らせる構成を示したもので、図１０で示した起電部２から通電する配線材３や固定式配線材３Ａに設けたコネクタ１０によって、図１１に示す配線材３とコネクタ１０の抜き差しで接続でき、そのコネクタ１０を接続した状態で足を踏み降ろすと、起電部２で起電した電気によってＬＥＤ６が発光する。そのＬＥＤ６が発光した光は、透光性樹脂で形成した面発光部９の導光式面発光部９ｂ内に入射し、その入射した光は所望の面形状に形成した樹脂内で反射拡散を繰り返すため、その所望の面形状に光らすことが可能である。光る靴会社を示す導光式面発光部９ｂとして、図１１ではプーマ社、ナイキ社、ニューバランス社のロゴマークを光らす構成になっている。所望の面形状に形成した導光式面発光部９ｂは、面ファスナー（マジックテープ（登録商標））等で靴の後面や側面に装着可能である。 FIG. 11 shows the configuration of an embodiment of the present invention in which light is emitted in a planar manner on the rear surface or side surface of the shoe. A light transmitting resin such as an acrylic material, a silicon material, or a vinyl chloride material has a light guiding property, and light incident in the resin repeats reflection and diffusion in the resin and becomes uniform light in the resin. It has the property of making the entire resin glow. The configuration shown in FIG. 11 actually shows a configuration in which the logo of the shoe is illuminated in a plane, and the connector provided on the wiring member 3 to be energized from the electromotive unit 2 shown in FIG. 10 or the fixed wiring member 3A. 11, the wiring member 3 can be connected by inserting and removing the connector 10. When the connector 10 is connected and the foot is stepped down, the LED 6 emits light by the electricity generated by the electromotive unit 2. The light emitted from the LED 6 is incident on the light guiding type surface light emitting portion 9b of the surface light emitting portion 9 formed of the light transmitting resin, and the incident light is reflected and diffused in the resin formed in the desired surface shape To repeat, it is possible to illuminate the desired surface shape. As a light guide type surface emitting unit 9b showing a glowing shoe company, in FIG. 11, the logo mark of Puma, Nike and New Balance is illuminated. The light guide type surface light emitting unit 9b formed in a desired surface shape can be attached to the rear surface or the side surface of the shoe with a surface fastener (magic tape (registered trademark)) or the like.

　図１２は、所望の文字や面状に光らせる他の実施例の構成を示したものであり、面発光部９としてフィルタ１２で遮蔽してその開口部を発光させる遮蔽式面発光部９ａで構成するものである。フィルタ１２に予め所望の文字や面状の開口部を形成し、そのフィルタ１２の後方から図示しないＬＥＤ６で光らせると、その光は形成した開口部のみ通過するため、所望の文字や面状の部分のみが光って視覚できる。 FIG. 12 shows the construction of another embodiment for making desired letters and surface light shine, and it is composed of a shielding type surface light emission portion 9a which is shielded by the filter 12 as the surface light emission portion 9 and which makes its opening emit light. It is If desired letters and planar openings are formed in the filter 12 in advance, and light is emitted from the rear of the filter 12 with the LED 6 (not shown), the light passes only through the formed apertures, so the desired letters and planar portions You can see only the light.

　図１３は、導光ファイバー１１によって光を導光し、導光式面発光部９ｂ内に光を入射させ導光させるようにした構成である。起電部２で起電した電気で発光したＬＥＤ６の光を導光ファイバー１１内に入射させると、その入射した光は導光ファイバー１１内で反射拡散を繰り返して送られ導光式面発光部９ｂ内へと入射される。その入射した光は導光式面発光部９ｂ内で反射拡散を繰り返すため、図１１で示した実施例と同様に所望の面形状に光らすことが可能である。導光ファイバー１１は適当に屈曲する素材で形成することで、靴内に設けた起電部２が起電し発光したＬＥＤ６の光を導光ファイバー１１内に入射させ、その導光ファイバー１１によって靴内で入射した光を靴の外へと導光することが可能である。 FIG. 13 shows a configuration in which light is guided by the light guide fiber 11, and light is made incident and guided in the light guide type surface light emitting section 9b. When the light of the LED 6 emitted by electricity generated by the electricity generation unit 2 is made to enter the light guiding fiber 11, the incident light is repeatedly reflected and diffused in the light guiding fiber 11, and is transmitted in the light guiding type surface light emitting unit 9b. It is incident on. Since the incident light is repeatedly reflected and diffused in the light guide type surface light emitting section 9b, it can be made to have a desired surface shape as in the embodiment shown in FIG. The light guiding fiber 11 is formed of a material that is appropriately bent, and the light of the LED 6 emitted and emitted by the electromotive unit 2 provided in the shoe is made to enter the light guiding fiber 11, and the light guiding fiber 11 It is possible to guide the incident light out of the shoe.

　尚、各実施例の構成において、ＬＥＤ６を覆ってその発光を拡散するカバーを設けてもよく、そのカバーを設けることで点状に光る発光を面状に光らせて発光でき、その面発光は夜間においては優しい疲れない発光で光らせることができる。また本発明において、起電部２で起電する起電流の電気信号を検出し、その電気信号によって歩数を計測する歩数計機能を具備してもよく、その歩数計機能の電源として例えばボタン電池を設けても、その電池の消耗は前記の電気信号を検出して表示するのみの消耗で済み、ＬＥＤ６を発光するための供給は全く必要無いため、その寿命をかなり伸ばすことができる。また前記上敷き２Ｄに足の裏を刺激する凸部を形成して構成しもよい。前述したように本発明の「靴の光装着具」であれば、既存のどんな靴にでも装着して、靴内に載置した平板状の起電部２を足踏みする運動によって、その圧電体で起電できて無電源で実施でき、しかもその起電する電気よって発光するＬＥＤ６の方向を、装着する人の所望する方向に向けて装着し発光できるようになるため、従来、幾つも提案されてた「光る靴」の各発明と比べても、従来に無い格段の効果があり、そして本発明の「靴の光装着具」であれば、後方と側方の２方向で同時に視覚できるように向けて発光させることも可能である。 In the configuration of each embodiment, a cover may be provided to cover the LED 6 to diffuse the light emission, and by providing the cover, light emission that emits in the form of dots can be emitted to make the surface emit light. In the light can be lit with a gentle and not tired light. In the present invention, a pedometer function may be provided to detect an electric signal of an electromotive current generated by the electromotive unit 2 and measure the number of steps by the electric signal. For example, a button battery may be used as a power source of the pedometer function. However, since the consumption of the battery can be consumed only by detecting and displaying the electric signal, and the supply for emitting the light of the LED 6 is not required at all, the life can be considerably extended. Moreover, the convex part which stimulates the sole of a foot may be formed and comprised in said overlay 2D. As described above, in the case of the "light fitting for shoes" of the present invention, the piezoelectric body is mounted on any existing shoes and exercised by stepping on the flat plate-like electromotive unit 2 placed in the shoes. In the prior art, many have been proposed because the LED 6 can be mounted and emitted in the direction desired by the person who wears it, since the direction of the LED 6 that emits light due to the electricity generated can be directed to the direction desired by the user.
