【００１８】
【発明の実施の形態】
｛実施の形態｝
以下、この発明の実施の形態に係る吊下装置について説明する。
【００１９】
図１は吊下装置を示す一部切欠概略斜視図である。
【００２０】
この吊下装置は、吊下支持装置１０と負荷付ハンガー３０とを備えている。
【００２１】
吊下支持装置１０は、負荷付ハンガー３０を吊下げ支持可能に構成されている。
【００２２】
本実施の形態では、吊下支持装置１０として、衣装用クローゼットを想定している。すなわち、吊下支持装置１０は、前面に観音開きの扉１２が設けられた筺状体１１と、その筺状体１１内に配設されたハンガーバー１５とを備えている。ハンガーバー１５の両端部は筺状体１１内の側面に支持され、これにより、該ハンガーバー１５は筺状体１１内の上部にその幅方向に掛渡すようにして配設支持されている。なお、このようなハンガーバー１５としては、上述した衣装用クローゼットに配設されるものの他、洗濯用物干し竿や衣服販売店舗での展示用の竿、クリーニング店用の竿、スポーツ関連施設のロッカー内に設けられる竿等を想定できる。
【００２３】
そして、衣装を掛けた負荷付ハンガー３０が前記ハンガーバー１５に着脱自在に吊下げて支持されるように構成されている。これにより、当該衣装が衣装用クローゼットとしての吊下支持装置１０内に収容される。
【００２４】
また、ハンガーバー１５には、その長手方向に沿って、給電線２０が配設されている。この給電線２０は、高周波電源２２に接続されており、負荷付ハンガーに対して非接触で給電を行う機能を有している。本実施の形態では、給電線２０は、ハンガーバー１５内に配設されている（図３参照）。なお、ハンガーバー１５の外周部に給電線２０を付設してもよい。
【００２５】
図２は、負荷付ハンガー３０を示す概略正面図である。
【００２６】
負荷付ハンガー３０は、ハンガー本体部３１と吊下部３５とを有するハンガー部と、受電部４０と、受電ユニット４５と、電気的負荷（以下単に負荷という）４８とを備えている。
【００２７】
ハンガー本体部３１は、略二等辺三角形枠状に形成されており、衣服を掛けることができるように構成されている。なお、負荷付ハンガー３０は、衣服用のものに限られない。例えば、工場等で所定の加工対象物（例えば鉄板等）を吊下げて支持するものであっても構わない。
【００２８】
吊下部３５は、支持部材であるハンガーバー１５に引っ掛け可能に構成されている。本実施の形態では、吊下部３５は、樹脂等の非磁性材料により形成されており、周方向の一部（より具体的には側方下部）が開口する環状の形状を有している。該吊下部３５の開口は、ハンガーバー１５を挿通可能な大きさに形成されている。そして、該開口を通ってハンガーバー１５を吊下部３５内に挿脱することで、吊下部３５がハンガーバー１５に着脱自在に引っ掛けられる。この吊下部３５の内部に次述する受電部４０が収容配置されている。
【００２９】
図３は負荷付ハンガー３０がハンガーバー１５に吊下げて支持された状態を示す断面図であり、図４は受電部４０に非接触で給電が行われる状態を示す説明図である。
【００３０】
受電部４０は、給電線２０から非接触で電力供給を受けるものであり、受電コア４１とコイル４４とを有している。
【００３１】
受電コア４１は、磁性材料により形成されており、吊下部３５の環状形状に倣う形状、即ち、周方向の一部が開口する環状形状を有しており、上記吊下部３５内に収容配置されている（図３参照）。コイル４４は、エナメル線等の巻線を受電コア４１に巻付けることによって形成されている。
【００３２】
そして、吊下部３５をハンガーバー１５に引っ掛けた状態で、ハンガーバー１５内の給電線２０に交流電流を流すと、給電線２０の周りに磁界が発生する。受電コア４１内の磁束が変化すると、該コイル４４に誘導電圧が励起され、この誘導電圧によって誘導電流が生じるようになっている。
【００３３】
受電ユニット４５と負荷４８とは、一体化された形態で、ハンガー本体部３１の上側コーナー部分に取付けられている（図２参照）。
【００３４】
負荷４８は、電力による駆動する電気的負荷であり、例えば、ハンガー本体部３１に掛けられた衣服に対して空気を送込む送風装置や同じく衣服に対してマイナスイオンを付与するイオン発生装置等である。そして、上記コイル４４からの出力電力が受電ユニット４５を介して負荷４８に供給されるようになっている。
【００３５】
図５は、吊下装置の電気的構成を示すブロック図である。
【００３６】
同図に示すように、商用電源２３が高周波電源２２に接続されると共に、高周波電源２２が給電線２０に接続されている。そして、商用電源２３から例えば１００Ｖの交流波が高周波電源２２に出力され、該高周波電源２２はこれをより高周波交流波に変換して給電線２０に出力する。これにより、給電線２０に交流電流が流れるようになる。
【００３７】
受電ユニット４５は、共振回路４５ａと整流回路４５ｂと定電圧回路４５ｃとを備えている。共振回路４５ａは受電コア４１のコイル４４に接続されており、定電圧回路４５ｃは負荷４８に接続されている。共振回路４５ａは、例えばＬＣ並列回路により構成されるもので、コイル４４からの出力について位相補償による有効電力の増大を行う。整流回路４５ｂは、前記共振回路４５ａより出力される交流波を直流波に変換して出力する回路である。定電圧回路４５ｃは、整流回路４５ｂより出力される直流電圧を負荷４８駆動用の設定電圧に変換する。このように所定電圧に整流された直流電圧が負荷４８に印加されることで、負荷４８は電力供給を受けて駆動する。
【００３８】
図６は、負荷付ハンガー３０の一使用例を示している。
【００３９】
同図の負荷付ハンガー３０には、負荷４８として送風装置が組込まれた場合を想定している。そして、負荷付ハンガー３０に例えば衣服としてのシャツＴが吊された状態で、給電線２０からの給電を受けて負荷（送風装置）４８が駆動して送風を行う。これにより、シャツＴの内部に空気が送込まれ、送風による所定の効果（乾燥、除湿等）が達成される。
【００４０】
以上のように構成された吊下装置によると、吊下支持装置１０の給電線２０から負荷付ハンガー３０に非接触で給電が行われる。このため、従来の有線式の給電方式のようなコネクタ接続等が不要で、又、電池式の給電方式のような電池交換や充電作業が不要となり、負荷付ハンガー３０を手軽に使用できる。また、電池式の給電方式のように、一次電池の交換が不要で、或は、充電池の寿命による交換をする必要が無く、半永久的な使用が可能で、維持コストを比較的低く抑えることができる。
【００４１】
また、従来の有線式の給電方式では、コネクタの接続位置や給電用のケーブルの長さ等により、配設位置に制約を受ける恐れがあったが、本吊下装置では、コネクタ接続が不要で、有線接続がなされていないので、配設位置の自由度の向上を図ることができる。また、給電用のケーブルがからまるようなこともなく、取り回しが容易である。さらに、従来の有線式の給電方式では、各負荷付ハンガーの設置個数に応じた数のコネクタが必要となっていたが、本吊下装置では、単一の給電線２０で非接触給電を行える。従って、複数の負荷付ハンガー３０を用いる場合でも、構成を簡易化できる。また、給電用の端子の露出箇所が無いため、ほこりの付着等による端子不良等も防止できる。また、受電部４０が吊下部３５に設けられると共に、給電線２０がハンガーバー１５に設けられているため、負荷付ハンガー３０を吊下げることで、容易に非接触給電を行えて便利である。
【００４２】
さらに、吊下部３５が周方向の一部が開口する環状形状に形成され、受電コア４１が該吊下部３５に環状形状に沿って配設されているため、磁路のギャップを低減することができ、効率的な給電を行える。
【００４３】
なお、吊下部３５は、必ずしも周方向の一部が開口する環状に形成されている必要はなく、例えば、後述する第２変形例では、吊下部３５Ｂは、通常状態では無開口環状となっている。
【００４４】
｛変形例｝
以下に、上記実施の形態の変形例について説明する。なお、下記各変形例の説明においては、上記実施の形態において説明した構成要素と同様構成要素については説明を省略し、相違点を中心に説明する。
【００４５】
図７に示す第１変形例は、吊下部３５及び受電部４０に係る変形例を示している。
【００４６】
この第１変形例では、吊下部３５Ｂは、可撓性樹脂等により、撓み変形自在で、周方向の一部が開口する環状の形状に形成されている。この開口の大きさは、ハンガーバー１５の直径よりも小さい。
【００４７】
また、受電部４０Ｂの受電コア４１Ｂは、複数の分割受電コア４２Ｂを備えている。各分割受電コア４２Ｂは、吊下部３５Ｂの環状形状に倣う弧状に形成されており、吊下部３５Ｂの環状形状に沿って適宜間隔をあけて配設されている。そのうちの少なくとも一つに巻線を巻付けることによってコイル４４Ｂが形成されている。複数の分割受電コア４２Ｂに亘って巻線を巻付けてもよい。
【００４８】
この第１変形例では、上記実施の形態における効果に加えて、吊下部３５Ｂはその開口を広げるようにして撓み変形自在であるため、図７の矢符Ａに示す方向に該開口を押し広げて該開口を通って吊下部３５Ｂ内にハンガーバー１５を挿入配置することで、吊下部３５Ｂをハンガーバー１５に引っ掛けることができる。また、同様に、該開口を広げて該開口を通ってハンガーバー１５を吊下部３５Ｂ外に抜き去ることで、吊下部３５Ｂをハンガーバー１５から取外すことができる。
【００４９】
そして、吊下部３５Ｂをハンガーバー１５に引っ掛けた状態では、吊下部３５Ｂの開口が比較的小さいため、磁路のギャップが比較的小さく、従って、効率的な給電を行える。
【００５０】
図８に示す第２変形例は、吊下部３５及び受電部４０に係る変形例を示している。
【００５１】
この第２変形例の負荷付ハンガー３０Ｃでは、吊下部３５Ｃは、一対の分割クリップ部３６Ｃを備えている。各分割クリップ部３６Ｃは、半円弧状の把持部３７Ｃと該把持部３７Ｃの下方に延びる操作部３８Ｃとを備えており、軸部３９Ｃを介して開閉自在に連結されている。両分割クリップ部３６Ｃは、図示省略の弾性部材により、把持部３７Ｃを閉じる方向に付勢されている。
【００５２】
そして、操作部３８Ｃを介して上方の両把持部３７Ｃを開閉することで、両把持部３７Ｃ間にハンガーバー１５が挿脱自在とされて、吊下部３５Ｃがハンガーバー１５に引っ掛けられるようになっている。
【００５３】
また、受電部４０Ｃは、一対の分割受電コア４２Ｃによって構成されている。各分割受電コア４２Ｃは、各把持部３７Ｃの形状に倣う半円弧形状に形成されており、各把持部３７Ｃの周方向に沿って配設されている。
【００５４】
従って、この第２の変形例では、上記実施の形態における効果に加えて、ハンガーバー１５を取巻くようにして半円弧状の分割受電コア４２Ｃを配設することができ、磁路のギャップを比較的小さくでき、効率的な給電を行える。
【００５５】
図９に示す第３変形例は、吊下部３５、受電部４０及び給電線２０の配設位置を変更した変形例を示している。
【００５６】
この第３変形例では、ハンガーバー１５Ｄの下方に該ハンガーバー１５Ｄの延在方向に沿って給電線２０Ｄが配設されている。また、ハンガーバー１５Ｄに吊下げて支持される吊下部３５Ｄの下部に給電線２０Ｄを挿通可能な受電部４０Ｄが配設されている。
【００５７】
この第３変形例でも、給電線２０Ｄから非接触で給電が行われるため、負荷付ハンガーを手軽に使用できる上、維持コストを比較的低く抑えることができるという点に関して、上記実施の形態と同様の効果を得ることができる。
【００５８】
図１０に示す第４変形例は、ハンガーバー１５及び給電線２０に係る変形例を示している。
【００５９】
この第４変形例では、支持部材１５Ｅは、バー１５Ｅａに、環状部と支持柱部とを有する環状支持部１５Ｅｂが垂設された構成とされている。
【００６０】
また、給電線２０Ｅはバー１５Ｅａから支持柱部を経由して環状部に沿って付設されている。
【００６１】
そして、吊下部３５が環状支持部１５Ｅｂの環状部内に引っ掛けるようにして支持される構成となっている。なお、環状支持部１５Ｅｂについては、周知のレール構造を適用してバー１５Ｅａの長手方向に沿って移動自在である。この場合、環状支持部１５Ｅｂとバー１５Ｅａとの電気的接続については、いわゆるパンタグラフ構造等を適用すればよい。
【００６２】
この第４変形例でも、給電線２０Ｅに交流電流を流すと、上記実施の形態と同様に、吊下部３５の受電コア４１内の磁束が変化し、コイル４４に誘導電流が生じ、負荷付ハンガーに対して非接触で給電を行え、上記実施の形態と同様の効果を得ることができる。
【００６３】
図１１に示す第５変形例は、ハンガーバー１５及び給電線２０に係る変形例を示している。
【００６４】
この第５変形例では、支持部材１５Ｆは、断面略Ｊ字状の長柱形状に形成されている。
【００６５】
また、給電線２０Ｆが、支持部材１５Ｆの上下方向の寸法が短い方の側部１５Ｆａに、その延在方向に沿って付設されている。
【００６６】
そして、吊下部３５が前記側部１５Ｆａに引っ掛けるようにして支持される。
【００６７】
従って、この第５変形例でも、給電線２０Ｆに交流電流を流すと、上記実施の形態と同様に、吊下部３５の受電コア４１内の磁束が変化し、コイル４４に誘導電流が生じ、負荷付ハンガー３０に対して非接触で給電を行え、上記実施の形態と同様の効果を得ることができる。
【００６８】
図１２に示す第６変形例は、ハンガーバー１５及び給電線２０に係る変形例を示している。
【００６９】
この第６変形例では、支持部材１５Ｇは、縦横の網状に形成されている。
【００７０】
また、給電線２０Ｇが、支持部材１５Ｇの水平方向に延びる各棒部材１５Ｇａに沿って適宜折曲しつつ付設されている。
【００７１】
そして、吊下部３５が前記棒部材１５Ｇａに引っ掛けるようにして支持される。
【００７２】
従って、この第６変形例でも、給電線２０Ｇに交流電流を流すと、上記実施の形態と同様に、吊下部３５の受電コア４１内の磁束が変化し、コイル４４に誘導電流が生じ、負荷付ハンガー３０に対して非接触で給電を行え、上記実施の形態と同様の効果を得ることができる。
【００７３】
これら第４〜第６変形例に示されるように、吊下部３５を支持する支持部材及び給電線は、必ずしも棒状体にその長手方向に沿って給電線を配設した構成に限られない。要するに、支持部材は吊下部３５を引っ掛け可能な形状を有していればよく、また、支持部材に吊下部３５が引っ掛けられた状態で、コイル４４の軸方向に方向に磁界が発生するように、給電線２０が配設されていればよい。
【００７４】
なお、上記各変形例は、相互に矛盾しない限りにおいて、適宜組合わせることができる。
【００７５】
【発明の効果】

Hereinafter, a suspension device according to an embodiment of the present invention will be described.
[0019]
FIG. 1 is a partially cutaway schematic perspective view showing a suspension device.
[0020]
This suspension device includes a suspension support device 10 and a hanger 30 with a load.
[0021]
The suspension support device 10 is configured to be able to suspend and support the hanger 30 with load.
[0022]
In the present embodiment, a closet for clothes is assumed as the suspension support device 10. That is, the suspension support device 10 includes a housing 11 provided with a double door 12 on the front surface thereof, and a hanger bar 15 disposed in the housing 11. Both ends of the hanger bar 15 are supported by side surfaces in the housing 11, whereby the hanger bar 15 is disposed and supported on an upper portion in the housing 11 so as to extend in the width direction thereof. In addition, as such a hanger bar 15, in addition to those provided in the above-mentioned clothes closet, a clothesline for washing, a pole for display at a clothing store, a pole for a cleaning shop, and a locker for a sports-related facility. A pole or the like provided inside can be assumed.

The load-carrying hanger 30 in which the costume is hung is detachably suspended from the hanger bar 15 and supported. Thereby, the costume is accommodated in the hanging support device 10 as a costume closet.
[0024]
The hanger bar 15 is provided with a power supply line 20 along the longitudinal direction. The power supply line 20 is connected to a high-frequency power supply 22 and has a function of supplying power to a hanger with a load in a non-contact manner. In the present embodiment, the power supply line 20 is provided inside the hanger bar 15 (see FIG. 3). The power supply line 20 may be attached to the outer periphery of the hanger bar 15.
[0025]
FIG. 2 is a schematic front view showing the hanger 30 with a load.
[0026]
The hanger 30 with a load includes a hanger unit having the hanger body 31 and the hanging portion 35, a power receiving unit 40, a power receiving unit 45, and an electric load (hereinafter simply referred to as a load) 48.
[0027]
The hanger main body 31 is formed in a substantially isosceles triangular frame shape, and is configured so that clothes can be hung thereon. Note that the hanger with load 30 is not limited to clothes. For example, a predetermined object to be processed (for example, an iron plate or the like) may be suspended and supported at a factory or the like.
[0028]
The hanging portion 35 is configured to be hooked on the hanger bar 15 as a support member. In the present embodiment, the hanging portion 35 is formed of a non-magnetic material such as a resin, and has an annular shape in which a part (more specifically, a lower side portion) in the circumferential direction is opened. The opening of the hanging portion 35 is formed in a size that allows the hanger bar 15 to be inserted. Then, the hanger bar 15 is inserted into and removed from the hanging portion 35 through the opening, so that the hanging portion 35 is detachably hooked to the hanger bar 15. A power receiving unit 40 described below is accommodated and arranged inside the hanging portion 35.
[0029]
FIG. 3 is a cross-sectional view showing a state in which the hanger with load 30 is suspended from and supported by the hanger bar 15, and FIG. 4 is an explanatory view showing a state in which power is supplied to the power receiving unit 40 in a non-contact manner.
[0030]
The power receiving unit 40 receives power from the power supply line 20 in a non-contact manner, and includes a power receiving core 41 and a coil 44.
[0031]
The power receiving core 41 is formed of a magnetic material, has a shape that follows the annular shape of the hanging portion 35, that is, has an annular shape that is partially open in the circumferential direction, and is housed and arranged in the hanging portion 35. (See FIG. 3). The coil 44 is formed by winding a winding such as an enameled wire around the power receiving core 41.
[0032]
Then, when an AC current is applied to the feeder line 20 in the hanger bar 15 in a state where the hanging portion 35 is hooked on the hanger bar 15, a magnetic field is generated around the feeder line 20. When the magnetic flux in the power receiving core 41 changes, an induced voltage is excited in the coil 44, and an induced current is generated by the induced voltage.
[0033]
The power receiving unit 45 and the load 48 are attached to the upper corner portion of the hanger body 31 in an integrated form (see FIG. 2).
[0034]
The load 48 is an electric load driven by electric power, and is, for example, a blower that sends air to clothes hung on the hanger main body 31 or an ion generator that similarly applies negative ions to clothes. is there. The output power from the coil 44 is supplied to the load 48 via the power receiving unit 45.
[0035]
FIG. 5 is a block diagram showing an electrical configuration of the suspension device.
[0036]
As shown in the figure, the commercial power supply 23 is connected to the high-frequency power supply 22, and the high-frequency power supply 22 is connected to the power supply line 20. Then, for example, a 100 V AC wave is output from the commercial power supply 23 to the high frequency power supply 22, and the high frequency power supply 22 converts this into a higher frequency AC wave and outputs it to the power supply line 20. As a result, an alternating current flows through the power supply line 20.
[0037]
The power receiving unit 45 includes a resonance circuit 45a, a rectifier circuit 45b, and a constant voltage circuit 45c. The resonance circuit 45a is connected to the coil 44 of the power receiving core 41, and the constant voltage circuit 45c is connected to the load 48. The resonance circuit 45a is configured by, for example, an LC parallel circuit, and increases the effective power of the output from the coil 44 by phase compensation. The rectifier circuit 45b is a circuit that converts an AC wave output from the resonance circuit 45a into a DC wave and outputs the DC wave. The constant voltage circuit 45c converts the DC voltage output from the rectifier circuit 45b into a set voltage for driving the load 48. When the DC voltage rectified to the predetermined voltage is applied to the load 48, the load 48 is driven by receiving power supply.
[0038]
FIG. 6 shows an example of use of the hanger 30 with a load.
[0039]
It is assumed that a blower is incorporated as the load 48 in the hanger 30 with load in FIG. Then, in a state in which, for example, a shirt T as clothes is hung on the hanger 30 with the load, the load (blower device) 48 is driven by receiving power supply from the power supply line 20 to blow air. Thereby, air is sent into the shirt T, and a predetermined effect (drying, dehumidification, etc.) by the blowing is achieved.
[0040]
According to the suspension device configured as described above, power is supplied from the power supply line 20 of the suspension support device 10 to the hanger 30 with load in a non-contact manner. This eliminates the need for a connector connection or the like as in a conventional wired power supply system, and eliminates the need for battery replacement and charging work as in a battery-powered power supply system, and allows the hanger 30 with load to be used easily. Also, unlike the battery-type power supply system, there is no need to replace the primary battery or the replacement due to the life of the rechargeable battery, it can be used semi-permanently, and the maintenance cost is relatively low. Can be.
[0041]
In addition, in the conventional wired power supply system, there is a possibility that the arrangement position is restricted by the connection position of the connector, the length of the power supply cable, and the like. Since no wired connection is made, the degree of freedom of the arrangement position can be improved. In addition, the power supply cable does not become entangled, and can be easily handled. Furthermore, in the conventional wired power supply system, a number of connectors is necessary according to the number of hangers with each load, but in the present suspension device, non-contact power supply can be performed with a single power supply line 20. . Therefore, even when a plurality of hanger 30 with a load is used, the configuration can be simplified. In addition, since there is no exposed portion of the power supply terminal, it is possible to prevent a terminal failure or the like due to dust or the like. In addition, since the power receiving unit 40 is provided in the hanging portion 35 and the power supply line 20 is provided in the hanger bar 15, by suspending the hanger 30 with a load, it is possible to easily perform non-contact power feeding, which is convenient.
[0042]
