【発明の属する技術分野】
本発明は、無線電話機用充電装置に関するものである。
【0002】
【従来の技術】
一般に、携帯電話やPHS等の移動通信体、或いは有線方式の電話機に付属するコードレス子機のような無線電話機は、送受信に必要な電力を得るための電池が内蔵されており、充電装置により定期的に充電を行う必要がある。
【0003】
斯かる無線電話機用の充電装置としては、従来、例えば、特開2001−57741号公報に記載されたようなものが存在し、これは、図7に示される如く、無線電話機としての携帯電話1の充電用端子(図示せず)が当接する給電用接片2を有し且つ携帯電話1を装着可能な卓上ホルダ3と、給電用コンセントに接続されるAC金属端子4を有し且つ交流電流を所定電圧値の直流電流に変換するACアダプタ5と、該ACアダプタ5に対しアダプタコード6を介して接続され且つ卓上ホルダ3の充電用端子に接続可能な接続プラグ7とを備えており、携帯電話1の充電を行う際には、アダプタコード6の接続プラグ7を卓上ホルダ3に接続し且つACアダプタ5のAC金属端子4を給電用コンセントに接続した状態で、卓上ホルダ3に携帯電話1を装着するようになっている。
【0004】
【発明が解決しようとする課題】
しかしながら、前述の如き従来の無線電話機用充電装置では、アダプタコード6の接続プラグ7が卓上ホルダ3に接続され且つACアダプタ5のAC金属端子4が給電用コンセントに接続されている場合、卓上ホルダ3に携帯電話1を装着していない状態であっても、卓上ホルダ3の給電用接片2には通電が行われているため、剥き出しの給電用接片2に誤って金属片や人体の肌等が触れると、ショートが発生したり火傷をしたりする虞があった。
【0005】
本発明は、斯かる実情に鑑み、卓上ホルダに無線電話機を装着していない状態では、給電用接片への通電を遮断し得、該給電用接片に対する金属片や人体の肌等の接触によるショートや火傷の発生を防止し得る無線電話機用充電装置を提供しようとするものである。
【0006】
【課題を解決するための手段】
本発明は、無線電話機の充電用端子が当接する給電用接片を有し且つ無線電話機を装着可能な卓上ホルダを備えてなる無線電話機用充電装置において、
無線電話機の卓上載置時に安定的姿勢を保持すべく当該無線電話機の背面に形成された凸状部が嵌入する凹部を、卓上ホルダの無線電話機装着面に形成すると共に、前記凹部内に、前記凸状部の嵌入時に給電用接片への通電をONにし且つ前記凸状部の非嵌入時に給電用接片への通電をOFFにするスイッチを前記凹部から外部に突出しないよう設けたことを特徴とする無線電話機用充電装置にかかるものである。
【0007】
上記手段によれば、以下のような作用が得られる。
【0008】
卓上ホルダに無線電話機を装着すると、無線電話機の背面に形成された凸状部が、卓上ホルダの無線電話機装着面に形成された凹部に嵌入し、スイッチがONとなって給電用接片への通電が行われ、無線電話機への充電が可能となる一方、卓上ホルダに無線電話機を装着していない状態では、スイッチがOFFとなって給電用接片への通電が行われなくなり、しかも、スイッチは凹部内に設けられており、卓上ホルダに無線電話機を装着しない限りはスイッチがONになることはないため、剥き出しの給電用接片に誤って金属片や人体の肌等が触れたとしても、ショートが発生したり火傷をしたりする心配はなくなる。又、スイッチは凹部内に設けられているため、卓上ホルダの無線電話機装着面に出っ張り部はなく、違和感のないデザインとなり、小型化も図れる。更に又、スイッチは、凸状部で押されてON、開放されてOFFとなるシンプルなもので済み、構造が簡単でコストも安く、且つ信頼性も高いものとなる。しかも、前記凸状部は、無線電話機の卓上載置時に安定的姿勢を保持すべく当該無線電話機の背面に形成されたものであるため、無線電話機の背面に、充電専用の凸状部を特別に設けなくて済む。
【0009】
【0010】
【0011】
【発明の実施の形態】
以下、本発明の実施の形態を図示例と共に説明する。
【0012】
図1〜図4は本発明を実施する形態の一例であって、図中、図7と同一の符号を付した部分は同一物を表わしており、基本的な構成は図7に示す従来のものと同様であるが、本図示例の特徴とするところは、図1〜図4に示す如く、無線電話機としての携帯電話1の背面に形成された凸状部としてのストラップ取付部8が嵌入する凹部9を、卓上ホルダ3の携帯電話装着面10に形成すると共に、該凹部9内に、前記ストラップ取付部8の嵌入時に給電用接片2への通電をONにし且つ前記ストラップ取付部8の非嵌入時に給電用接片2への通電をOFFにするスイッチ11を設けた点にある。
【0013】
本図示例の場合、前記卓上ホルダ3は、図1及び図2に示す如く、下側ケース12と上側ケース13とを一体に組み付けてなり、その内部には、携帯電話1の充電用端子14が当接する給電用接片2が一体化された基板15が設けられ、該基板15上に前記スイッチ11を取り付けてある。
【0014】
前記スイッチ11は、前記基板15上に取り付けられたスイッチ本体11aと、該スイッチ本体11aから所要量だけ突出するスイッチ頭部11bとを備えており、該スイッチ頭部11bは、前記卓上ホルダ3の携帯電話装着面10に形成された凹部9内に収まり、該凹部9から外部へ突出しないようにしてある。
【0015】
尚、前記卓上ホルダ3内には、スプリング16の付勢力により上側ケース13の小孔17から先端部が所要量だけ突出するようピン18を中心に枢支された係合爪19を配設してあり、携帯電話1の充電時には、図2に示す如く、係合爪19を携帯電話1の係合溝23に係合させ、卓上ホルダ3に対して携帯電話1を固定するようにしてある。
【0016】
一方、前記ストラップ取付部8は、図3及び図4に示す如く、携帯電話1の背面における幅方向一端側に突出形成されたアンテナ20の収納部21に対応させて、携帯電話1の卓上載置時に安定的姿勢を保持すべく、携帯電話1の背面における幅方向他端側に突出形成されたものである。
【0017】
次に、上記図示例の作動を説明する。
【0018】
卓上ホルダ3に携帯電話1を装着すると、携帯電話1の背面に形成された凸状部としてのストラップ取付部8が、卓上ホルダ3の携帯電話装着面10に形成された凹部9に嵌入し、スイッチ11がONとなって給電用接片2への通電が行われ、携帯電話1への充電が可能となる一方、卓上ホルダ3に携帯電話1を装着していない状態では、スイッチ11がOFFとなって給電用接片2への通電が行われなくなり、しかも、スイッチ11は凹部9内に設けられており、卓上ホルダ3に携帯電話1を装着しない限りはスイッチ11がONになることはないため、剥き出しの給電用接片2に誤って金属片や人体の肌等が触れたとしても、ショートが発生したり火傷をしたりする心配はなくなる。又、スイッチ11は凹部9内に設けられているため、卓上ホルダ3の携帯電話装着面10に出っ張り部はなく、違和感のないデザインとなり、小型化も図れる。更に又、スイッチ11は、凸状部としてのストラップ取付部8で押されてON、開放されてOFFとなるシンプルなもので済み、構造が簡単でコストも安く、且つ信頼性も高いものとなる。
【0019】
又、本図示例の場合、凸状部を、携帯電話1の卓上載置時に安定的姿勢を保持すべくその背面に形成されたストラップ取付部8で兼用するようにしてあるため、携帯電話1の背面に、充電専用の凸状部を特別に設けなくて済む。
【0020】
こうして、卓上ホルダ3に携帯電話1を装着していない状態では、給電用接片2への通電を遮断し得、該給電用接片2に対する金属片や人体の肌等の接触によるショートや火傷の発生を防止し得る一方、卓上ホルダ3のデザインを阻害せず小型化も図ることができ、更に、構造の複雑化を避けてコストも安くでき且つ信頼性も高めることができ、又、携帯電話1の背面に、充電専用の凸状部を特別に設ける必要もない。
【0021】
図5及び図6は本発明を実施する形態の他の例であって、図中、図1〜図4と同一の符号を付した部分は同一物を表わしており、携帯電話1の背面における幅方向略中央部に、卓上載置時に安定的姿勢を保持するための凸状部22が形成されている場合に、該凸状部22が嵌入する凹部9を、卓上ホルダ3の携帯電話装着面10の対応する位置に形成すると共に、該凹部9内に、前記凸状部22の嵌入時に給電用接片2への通電をONにし且つ前記凸状部22の非嵌入時に給電用接片2への通電をOFFにするスイッチ11を設けるようにしたものである。
【0022】
尚、この例におけるストラップ取付部8’は、単なる孔となっている。
【0023】
図5及び図6に示す例においては、卓上ホルダ3に携帯電話1を装着すると、携帯電話1の背面に形成された凸状部22が、卓上ホルダ3の携帯電話装着面10に形成された凹部9に嵌入し、スイッチ11がONとなって給電用接片2への通電が行われ、携帯電話1への充電が可能となる一方、卓上ホルダ3に携帯電話1を装着していない状態では、スイッチ11がOFFとなって給電用接片2への通電が行われなくなり、しかも、スイッチ11は凹部9内に設けられており、卓上ホルダ3に携帯電話1を装着しない限りはスイッチ11がONになることはないため、剥き出しの給電用接片2に誤って金属片や人体の肌等が触れたとしても、ショートが発生したり火傷をしたりする心配はなくなり、又、スイッチ11は凹部9内に設けられているため、卓上ホルダ3の携帯電話装着面10に出っ張り部はなく、違和感のないデザインとなり、小型化も図れ、更に又、スイッチ11は、凸状部22で押されてON、開放されてOFFとなるシンプルなもので済み、構造が簡単でコストも安く、且つ信頼性も高いものとなる。
【0024】
又、図5及び図6に示す例においては、凸状部22を、無線電話機の卓上載置時に安定的姿勢を保持すべくその背面に形成されたもので兼用するようにしてあるため、携帯電話1の背面に、充電専用の凸状部22を特別に設けなくて済む。
【0025】
こうして、図5及び図6に示す例の場合も、図1〜図4に示す例の場合と同様、卓上ホルダ3に携帯電話1を装着していない状態では、給電用接片2への通電を遮断し得、該給電用接片2に対する金属片や人体の肌等の接触によるショートや火傷の発生を防止し得る一方、卓上ホルダ3のデザインを阻害せず小型化も図ることができ、更に、構造の複雑化を避けてコストも安くでき且つ信頼性も高めることができ、又、携帯電話1の背面に、充電専用の凸状部22を特別に設ける必要もない。
【0026】
尚、本発明の無線電話機用充電装置は、上述の図示例にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【0027】
【発明の効果】
以上、説明したように本発明の請求項1記載の無線電話機用充電装置によれば、無線電話機の背面に、充電専用の凸状部を特別に設けることなく給電用接片への通電をON・OFFでき、卓上ホルダに無線電話機を装着していない状態では、給電用接片への通電を遮断し得、該給電用接片に対する金属片や人体の肌等の接触によるショートや火傷の発生を防止し得る一方、卓上ホルダのデザインを阻害せず小型化も図ることができ、更に、構造の複雑化を避けてコストも安くでき且つ信頼性も高めることができるという優れた効果を奏し得る。
