【発明の詳細な説明】 2個の相対回転可能かつ電気的接続可能な継手部材を有する継手及びこのよう な継手を設けた真空クリーナ 本発明は、継手の回転軸線の周りに互いに回転することができるとともに、互 いに電気的に接続できる第1継手部材及び第2継手部材とを具え、第1継手部材 は第2継手部材のリング状位置決め枠内に掛合するリング状電気接点に接触でき る電気接点を有する継手に関するものである。 更に、本発明は、本発明による継手を使用するのに好適であってリング状電気 接点を有する継手部材に関するものである。 更にまた本発明は、ハウジングと、このハウジング内に収納した吸引ユニット と、ハウジング及び吸引ユニットに可撓性吸引ホースを介して接続しうる吸引ツ ールを具える真空クリーナに関するものである。 更に、本発明は、ハウジングと、このハウジング内に収納した吸引ユニットと 、ハンドルを有しかつハウジング及び吸引ユニットに可撓性吸引ホースを介して 接続しうる吸引ツールを具える真空クリーナに関するものである。 更にまた本発明は、本発明による真空クリーナに使用するのに好適であって本 発明による継手部材を設けた吸引ホース及び吸引ツールに関するものである。 吸引ホースを真空クリーナのハウジングにこのような継手を介して接続する冒 頭のパラグラフに述べたタイプの継手及び上述の真空クリーナは米国特許第4, 550,958号に記載されている。この既知の継手は、2個の継手部材の共通 中心軸線に一致する回転軸線の周りに相対回転可能な2個の管状継手部材を有す る。既知の真空クリーナの吸引ホースの第1端部を接続することによって真空ク リーナのハウジングに接続することができ、このハウジング内に吸引ユニットを 収納する。吸引ホースの第2端部は吸引ツールに接続することができる。既知の 継手における管状継手部材並びに吸引ホースは、吸引ツールを介して吸引したゴ ミ及びほこり粒子をハウジング内のダスト容器に吸い込むダクトに属する。継手 の2個の継手部材は相対回転できるため、真空クリーナのユーザーは、真空クリ ーナのハウジングを移動させることなく、吸引ツールによって真空クリーナの周 りの大きな領域を掃除することができる。 既知の真空クリーナの吸引ホースは多数の電気導体を有し、真空クリーナのハ ウジングから吸引ツールへ、また吸引ツールからハウジングへ電流又は電圧を供 給することができる。吸引ツールには例えば、ブラシを駆動する電動モータを設 けておき、ハウジングから吸引ホースの電気導体を介して動作させ、又は電気制 御手段又は電子制御手段を設け、この制御手段からの電気信号をハウジングに吸 引ホースの電気導体を介して転送するようにしている。吸引ホースの電気導体は 継手の第1継手部材の多数の電気接点にプラグ及びソケットを介して接続するこ とができる。第1継手部材の電気接点は第2継手部材の多数のリング状電気接点 に圧着し、これらの第2継手部材のリング状電気接点は継手の回転軸線に対して 同心状に配置する。このようにして、継手部材間の相対回転中に第1継手部材の 電気接点は第2継手部材のリング状電気接点との接触を維持し、継手部材間の相 対回転は制限なく行うことができる。 既知の第2継手部材のリング状電気接点はそれぞれ第2継手部材の接点ホルダ の環状位置決め溝に配置し、このホルダは2個のシェルを有する。既知の継手の 組み立て中に、リング状電気接点を接点ホルダの2個のシェルの周りに配置し、 位置決め溝内に取り付け、この後接点ホルダをリング状接点とともに管状ホルダ の周りに滑り込ませる。この管状ホルダは複数個の拡開脚を有し、これら脚によ って接点ホルダのシェルを互いに引き離し、リング状接点を位置決め溝内に保持 することができる。従って、既知の継手は部品点数が比較的多く、継手の組み立 てに時間がかかる。 本発明の目的は、継手を組み立てるのに必要な部品点数及び時間をできるだけ 制限することができる冒頭に述べたタイプの継手を得るにある。 この目的を達成するため、本発明継手は、前記リング状電気接点を弾性変形可 能にし、かつ前記回転軸線に対して半径方向に指向する弾性予張力の作用の下に 前記リング状位置決め枠に掛合させたことを特徴とする。リング状電気接点は弾 性的に変形することができるため、例えば、拡開ツールによって、第2継手部材 を分離することなく、第2継手部材の位置決め枠内にリング状電気接点を配置す ることができる。リング状電気接点は弾性予張力によって位置決め枠内に保持さ れ、この予張力は回転軸線に対して半径方向に指向する。従って、リング状電気 接点の使用によって、位置決め枠を有する第2継手部材は、例えば、射出成形プ ロセスにより単一の一体部品として製造することができ、継手の組み立てに要す る部品点数と時間をできるだけ制限することができるようになる。 本発明による継手の特別な実施例においては、前記リング状位置決め枠におけ るリング状電気接点の直径を、リング状電気接点の位置決め枠に取り付ける前の 無負荷状態での直径よりも大きくする。継手の組み立て中、リング状電気接点の 直径は例えば、拡開ツールによって大きくし、この後リング状電気接点を第2継 手部材の位置決め枠内に掛合させることができる。リング状電気接点の直径が増 大するとき、リング状電気接点は弾性的に変形し、従って、リング状電気接点の 中心軸線に対して半径方向に指向する予張力をリング状電気接点内に発生する。 この予張力は、リング状電気接点が位置決め枠内に掛合した後も保持される。即 ち、位置決め枠の直径がリング状電気接点の位置決め枠に取り付ける前の無負荷 状態の直径よりも大きいためであり、回転軸線に対して半径方向に指向する予張 力を構成し、位置決め枠内にリング状電気接点を保持する作用を有するためであ る。 本発明継手の他の実施例においては、リング状電気接点を螺旋ばねによって構 成する。螺旋ばねを環状位置決め枠内に嵌合するとき、螺旋ばねは簡単かつ信頼 性高く所要の直径となることができる。螺旋ばねは複数個の連続した巻回を有す るため、螺旋ばね上を摺動する第1継手部材の電気接点の磨耗を少なくする。 本発明による継手の他の実施例においては、リング状電気接点を電気導体に電 気的に接続し、この電気導体をリング状電気接点とリング状位置決め枠との間に 前記弾性予張力の下にクランプする。このようにして、リング状電気接点を位置 決め枠内に保持する弾性予張力はクランプ力をも構成し、このクランプ力によっ て電気導体をリング状電気接点に接触させる。従って、継手には電気導体をリン グ状電気接点に取り付けるための他の手段を必要としない。従って、継手の部品 点数を一層減少することができる。 本発明による継手のメリットを有する冒頭に述べたタイプの真空クリーナにお いて、吸引ホースをハウジングに本発明による継手によって接続することができ る。 更に、本発明による継手のメリットを有する冒頭に述べたタイプの真空クリー ナにおいて、吸引ツールのハンドルを本発明による継手によって吸引ホースに接 続することができる。 以下に図面につき本発明を詳細に説明する。 図1は、本発明による継手を設けた真空クリーナの線図的説明図、 図2は、図1の真空クリーナの吸引ツールのハンドル部分と吸引ホースの一方 の端部を示す線図的説明図、 図3は、図1の真空クリーナに使用される本発明による継手の断面図、 図4Aは、図3に示す継手の継手部材とリング状電気接点の線図的説明図、 図4Bは、図4Aに示す継手部材の周りに、図4Aに示すリング状電気接点を 嵌着する方法を示す線図的説明図である。 図1に示す真空クリーナ1は、プラスチック製のハウジング3を有し、このハ ウジング3は複数個のホイール5によって表面7上に配置することができる。ハ ウジング3は電気的に駆動する吸引ユニット9を収容し、この吸引ユニット9は 図1に線図的のみ示す。真空クリーナ1には、更に、吸引ノズル13と、金属ワ ンド(杖)15と、ハンドル17よりなる吸引ツール11を有する。吸引ツール 11のハンドル17は真空クリーナ1の可撓性吸引ホース21に第1継手19に より接続するとともに、吸引ホース21はハウジング3の吸引ポート25に第2 継手23によって着脱自在に接続する。吸引ポート25は真空クリーナ1のダス ト容器27に開口し、このダスト容器27は吸引ユニット9にフィルタ29を介 して接続する。動作にあたり、吸引ユニット9はダスト容器27、吸引ホース2 1、及び吸引ツール11内に部分的な真空を発生し、この結果、表面7上のゴミ やほこりの粒子を、吸引ツール11の吸引ノズル13及び吸引ホース21を経て ダスト容器27に吸い込む。 図1に示すように、ハンドル17は吸引ユニット9のための制御手段31を担 持し、真空クリーナ1のユーザーが吸引ユニット9の吸引パワーを調整できるよ うにする。制御手段31は、例えば、図1には示さない可変抵抗により構成し、 スライド制御部材33によって制御できるようにする。図2に示すように、制御 手段31は、吸引ホース21のジャケット内に互いに対角線方向に対向させて形 成した2個のダクト37a,37bに配置した2個の電気導体35a,35bに よって吸引ユニット9に電気的に接続可能にする。 更に、図2に示すように、ハンドル17を吸引ホース21に接続する第1継手 19は、ハンドル17に取り付けた管状の第1継手部材39と、吸引ホース21 に取り付けた管状の第2継手部材41とにより構成する。第1継手部材19の継 手部材39,41は、管状継手部材39,41の共通中心軸線に一致する継手部 材19の回転軸線43の周りに相対回転可能にする。継手部材39,41が互い に相対回転できることによって操作性がよくなる。 図3は、第1継手19の継手部材39,41の断面を示す。図2及び図3に示 すように、第2継手部材41は、回転軸線43に一致する中心軸線を有する円筒 形ユニオン45を有する。このユニオン45は吸引ホース21の端部49に連結 する。可撓性プラスチック製のスリーブ51を吸引ホース21の端部49の周り に嵌着し、またこのスリーブ51には切除部53と傾斜したロック用の突起55 を設ける。この突起55の各々をC字状の切除部54によって包囲し、スリーブ 51に対して回転軸線43に関して半径方向に曲がることができるようにする。 図2に示す組立体において、ユニオン54及びスリーブ51は回転軸線の周りに 相対回転できるとともに、スリーブ51は吸引ホース21上を軸線方向にユニオ ン45の環状止め部59まで摺動できる。第1継手部材39は、スリーブ51の 外径に対応する内径を有するブッシュ61を有する。2個の継手部材39,41 を互いに接続した状態の図3に示す組立体においては、スリーブ51のロック用 突起55がブッシュ61の開口63に掛合し、この結果、スリーブ51が第1継 手部材39に対して軸線方向の移動と相対回転とを阻止される。第2継手部材4 1のユニオン45はこのとき、スリーブ51と第1継手部材39のブッシュ61 の他の環状止め部64との間にクリアランスなく軸線方向の移動を阻止される。 この結果、第2継手部材41は第1継手部材39に対して軸線方向の移動を阻止 され、また継手部材39,41は回転軸線43の周りに相対回転することができ る。継手部材39,41、ロック用突起55、及び開口63を有する第1継手1 9は、ハンドル17を吸引ホース21に永久的に接続するものとすることができ る。また第1継手19を着脱自在の継手として構成することもできる。このとき 、第1継手19は例えば、1個の開口63に掛合する1個の可撓性ロック用突起 55を設け、1個のロック用突起55を回転軸線43の方向に曲げ、次いで継手 部材39,41を引き離すことによって真空クリーナ1のユーザーがハンドル1 7と吸引ホース21とを分離できるようにする。 回転軸線43と同心状の第1環状溝67及び第2環状溝69をユニオン45の 外壁に形成しておき、それぞれ第1リング状電気接点71及び第2リング状電気 接点73のための位置決め枠とする。図2及び図3に示すように、リング状電気 接点71,73の各々は、以下に説明するように、環状溝67,69内にリン青 銅製の螺旋ばね75,77により構成する。螺旋ばね75,77は回転軸線43 に対して半径方向に拡開され、この拡開に関連して螺旋ばね75,77に存在す る半径方向に指向する弾性予張力によって溝67,69内に保持する。 図2に示すように、吸引ホース21の電気導体35aを第2継手部材41の第 1リング状電気接点71に電気的に接続し、また電気導体35bを第2リング状 電気接点73に電気的に接続する。図2に示すように、電気導体35aのための ダクト37aを第2環状溝69及び第1及び第2の環状溝67,69間の隆起部 81に形成した溝孔79に終端させる。溝孔79は、第1環状溝67のフック状 溝孔83に連通させ、螺旋ばね75の弾性予張力の作用の下に導体35aの一方 の端部を螺旋ばね75と溝67に形成した多数のぎざぎざのうねとの間にクラン プする。電気導体35bのためのダクト37は、第2環状溝69のフック状溝孔 87に終端させ、螺旋ばね77の弾性予張力の作用の下に、電気導体35bの一 方の端部を螺旋ばね77と第2環状溝69に形成した多数のぎざぎざのうね85 との間にクランプする。 更に、図2及び図3に示すように、第1継手部材39のブッシュ61には第1 開口91及び第2開口93を設ける。継手部材39の第1電気接点95を第1開 口93内に配置し、継手部材39の第2電気接点97を第2開口93内に配置す る。電気接点95,97の各々はリン青銅の可撓性突片99,101を有する。 図3に示すように、第1電気接点95の突片99は、第2継手部材41の第1リ ング状電気接点71に向けて予張力を与えられ、また第2電気接点97は第2継 手部材41の第2リング状電気接点73に向けて予張力を与えられている。突片 99,101のこの予張力は、第1継手部材39の電気接点95,97と第2継 手部材41の電気接点71,73との間に適切な接点掛合力を生ずる。ストリッ プ状の電気導体103a,103bによって、突片99,101はハンドル17 内の制御手段31に接続され、ストリップ状の導体103a,103bの各々は ハンドル17のダクト105a,105bに貫通する。ハンドル17における制 御手段31は、ストリップ状の導体103a,103b、第1継手部材39の電 気接点95,97、第2継手部材41のリング状電気接点71,73、及び吸引 ホース21内の電気導体35a,35bを介して吸引ユニット9に電気的に接続 される。リング状電気接点71,73は回転軸線43に対して同心状に配置され ているため、真空クリーナ1の使用中に第1継手19の継手部材39,41が相 対的に回転するときも第1継手部材39の電気接点95,97は第2継手部材4 1のリング状電気接点71,73との接触状態を維持する。このことにより、回 転軸線43の周りの継手部材39,41間の相対回転を制限なく可能にする。 図4aは、第1継手19を組み立てる前における第2継手部材41のユニオン 45及び第2リング状電気接点73の螺旋ばね77の状態を示す。リング状電気 接点73のためのリング状位置決め枠を構成するユニオン45の第2環状溝69 は、継手19を組み立てる前の無負荷状態の螺旋ばね77の直径D2よりも大き い外径D1を有する。図示の実施例においては、D1を約40mmとし、D2を約 30mmとし、リン青銅螺旋ばね77の線径を約0.6mmとする。図4bには 、螺旋ばね77をユニオン45の溝69内に嵌合させる拡開ツール107を示す 。この拡開ツール107は複数個の例えば、3個又は4個の互いに平行で互いに 対する距離を調整自在にしたピン109を有する。螺旋ばね77を拡開ツール1 07のピン109の周りに配置し、この後ピン間の距離を増大させて螺旋ばね7 7の直径を大きくし、螺旋ばねを弾性変形させる。変形した螺旋ばね77の直径 が直径D1よりも大きくなったとき、螺旋ばね77を溝69の周りに配置し、こ の後拡開ツール107を取り出し、螺旋ばね77を溝69に掛合させる。溝69 の直径D1は無負荷状態の螺旋ばね77の直径D2よりも大きいため、螺旋ば ね77は溝69内にあるとき弾性予張力を有する。この予張力は回転軸線43に 対して半径方向に指向し、従って、螺旋ばね77は予張力によって溝69内に保 持される。 螺旋ばね77は、拡開ツール107によって溝69内に簡単に取り付けること ができるため、第2継手部材41のユニオン45は螺旋ばね77の取り付ける際 に分解する必要がない。第2継手部材41のユニオン45は、単一の一体部品と して例えば、射出成形プロセスによって製造することができ、従って、第1継手 19として組み立てる部品点数を減少することができる。螺旋ばね75,77に おける弾性予張力は電気導体35a,35bの端部のクランプ力としても使用す るため、第1継手19は導体35a,35bを螺旋ばね75,77に取り付ける ための他の手段を必要とせず、従って、第1継手19として組み立てる部品点数 を減少することができる。 吸引ホース21をハウジング3の吸引ポート25に接続する第2継手23は第 1継手19と類似の構成とすることができ、従って、詳細には説明しない。しか し、上述のように、吸引ホース21は吸引ポート25に着脱自在に接続し、この ため、第2継手23には1個のロック用突起55のみを設け、吸引ホース21を 吸引ポート25から分離するには真空クリーナ1のユーザーが第2継手23の回 転軸線に向かってこのロック用突起55を曲げることができるようにする。 上述の継手19,23のリング状電気接点71,73の各々は、螺旋ばね75 ,77により構成する。しかし、螺旋ばね75,77の代わりに他の弾性変形可 能なリング状電気接点を設けることもできる。例えば、円筒形スリーブとして曲 げたストリップとすることができる。位置決め枠に取り付ける前の無負荷状態で はこのようなスリーブは位置決め枠の直径よりも小さい直径とし、ストリップの 端部を互いにオーバーラップさせる。ストリップの長さは、ストリップを位置決 め枠内に嵌合したときストリップ端部が互いに突き合わさる長さとする。 上述したことろは、真空クリーナ1に本発明による継手19,23を使用した 実施例を説明した。しかし、このような継手は他の装置にも使用できる。例えば 、照明の固定具に使用でき、第1継手部材を照明の固定具のベース部分に取り付 け、第2継手部材をランプソケットのような照明固定具の一部に取り付け、照明 の固定具のベースに対して回転できるようにする。本発明による継手は、また例 えば、電気コードのためのワインダにも使用することができ、電気コードを巻き 取るべきベースに対して相対回転できるよう第1継手部材をコードワインダの一 部に取り付ける。 上述の継手19,23の各々は、2個の電気接点95,97に接触することが できる2個のリング状電気接点71,73を有する。しかし、本発明による継手 には異なる数の電気接点、例えば、3個又はそれ以上の数の電気接点を設けるこ ともできる。 上述の継手19,23では、リング状電気接点71,73と電気導体35a, 35bとの間の電気的接続をリング状電気接点71,73の弾性予張力の下に導 体35a,35bをクランプすることによって得ている。しかし、導体35a, 35bとリング状電気接点71,73との間の電気的接続を異なる方法例えば、 それ自体既知のはんだ付けによって行うこともできる。DETAILED DESCRIPTION OF THE INVENTION A joint having two relatively rotatable and electrically connectable joint members and a vacuum

Furthermore, the present invention relates to a suction hose and a suction tool suitable for use in the vacuum cleaner according to the present invention and provided with the joint member according to the present invention. A fitting of the type mentioned in the opening paragraph, which connects the suction hose to the housing of the vacuum cleaner via such a fitting, and the vacuum cleaner described above are described in US Pat. No. 4,550,958. This known joint has two tubular joint members which are relatively rotatable about an axis of rotation which coincides with the common central axis of the two joint members. It can be connected to the housing of the vacuum cleaner by connecting the first end of the suction hose of a known vacuum cleaner, in which the suction unit is housed. The second end of the suction hose can be connected to a suction tool. The tubular fitting member and the suction hose in the known fitting belong to a duct that sucks dirt and dust particles sucked through the suction tool into a dust container in the housing. Since the two fitting members of the fitting can rotate relative to each other, a user of the vacuum cleaner can clean a large area around the vacuum cleaner with a suction tool without having to move the housing of the vacuum cleaner. The suction hoses of known vacuum cleaners have a large number of electrical conductors and can supply current or voltage from the vacuum cleaner housing to the suction tool and from the suction tool to the housing. The suction tool is provided with, for example, an electric motor for driving a brush and is operated from the housing through an electric conductor of a suction hose, or an electric control means or an electronic control means is provided, and an electric signal from this control means is supplied to the housing. The suction hose is designed to be transferred through the electrical conductor. The electrical conductors of the suction hose can be connected via plugs and sockets to a number of electrical contacts of the first coupling member of the coupling. The electrical contacts of the first joint member are crimped onto a number of ring-shaped electrical contacts of the second joint member, the ring-shaped electrical contacts of these second joint members being arranged concentrically to the axis of rotation of the joint. In this way, the electrical contacts of the first coupling member maintain contact with the ring-shaped electrical contacts of the second coupling member during relative rotation between the coupling members, and relative rotation between the coupling members can take place without limitation. . The known ring-shaped electrical contacts of the second coupling element are each arranged in the annular positioning groove of the contact holder of the second coupling element, which holder has two shells. During the assembly of the known coupling, the ring-shaped electrical contacts are placed around the two shells of the contact holder and mounted in the locating grooves, after which the contact holder is slid around the tubular holder together with the ring-shaped contacts. The tubular holder has a plurality of spreading legs that allow the shells of the contact holders to be pulled apart from each other and retain the ring-shaped contacts in the positioning groove. Therefore, the known joint has a relatively large number of parts, and it takes time to assemble the joint. The object of the invention is to obtain a joint of the type mentioned at the outset in which the number of parts and the time required for assembling the joint can be limited as much as possible. In order to achieve this object, the joint of the present invention makes the ring-shaped electrical contact elastically deformable, and engages with the ring-shaped positioning frame under the action of elastic pre-tension directed in the radial direction with respect to the rotation axis. It is characterized by having done. Since the ring-shaped electrical contact can be elastically deformed, it is possible to dispose the ring-shaped electrical contact in the positioning frame of the second joint member without separating the second joint member, for example, by a spreading tool. it can. The ring-shaped electrical contacts are held in the locating frame by elastic pretension, which pretension is directed radially with respect to the axis of rotation. Therefore, by using the ring-shaped electrical contacts, the second joint member having a positioning frame can be manufactured as a single integral part, for example by an injection molding process, limiting the number of parts and the time required for assembling the joint as much as possible. You will be able to. In a special embodiment of the joint according to the invention, the diameter of the ring-shaped electrical contacts in the ring-shaped positioning frame is larger than the diameter of the ring-shaped electrical contacts in the unloaded state before being attached to the positioning frame. During assembly of the joint, the diameter of the ring-shaped electrical contact can be increased, for example, by a spreading tool, after which the ring-shaped electrical contact can be engaged in the positioning frame of the second coupling member. As the diameter of the ring-shaped electrical contact increases, the ring-shaped electrical contact elastically deforms, thus generating a pre-tension in the ring-shaped electrical contact that is directed radially with respect to the central axis of the ring-shaped electrical contact. . This pretension is retained even after the ring-shaped electrical contacts are engaged in the positioning frame. That is, because the diameter of the positioning frame is larger than the diameter of the ring-shaped electrical contact in the unloaded state before being attached to the positioning frame, a pretension directed in the radial direction with respect to the rotation axis is formed, and This is because it has a function of holding the ring-shaped electrical contact. In another embodiment of the joint according to the invention, the ring-shaped electrical contact is constituted by a spiral spring. When fitting the spiral spring into the annular locating frame, the spiral spring can easily and reliably reach the required diameter. Since the spiral spring has a plurality of continuous windings, it reduces wear on the electrical contacts of the first joint member sliding on the spiral spring. In another embodiment of the coupling according to the invention, the ring-shaped electrical contact is electrically connected to an electrical conductor, the electrical conductor being between the ring-shaped electrical contact and the ring-shaped positioning frame under the elastic pretension. To clamp. In this way, the elastic pretension which holds the ring-shaped electrical contact in the positioning frame also constitutes a clamping force, which causes the electrical conductor to come into contact with the ring-shaped electrical contact. Therefore, the fitting does not require any other means for attaching the electrical conductors to the ring-shaped electrical contacts. Therefore, the number of parts of the joint can be further reduced. In a vacuum cleaner of the type mentioned at the outset, which has the advantages of the coupling according to the invention, a suction hose can be connected to the housing by means of the coupling according to the invention. Furthermore, in a vacuum cleaner of the type mentioned at the outset, which has the advantages of the coupling according to the invention, the handle of the suction tool can be connected to the suction hose by means of the coupling according to the invention. The present invention will be described in detail below with reference to the drawings.

FIG. 4B is a diagrammatic explanatory view showing a method of fitting the ring-shaped electrical contact shown in FIG. 4A around the joint member shown in FIG. 4A. The vacuum cleaner 1 shown in FIG. 1 has a plastic housing 3, which can be arranged on a surface 7 by means of a plurality of wheels 5. The housing 3 contains an electrically driven suction unit 9, which is shown diagrammatically only in FIG. The vacuum cleaner 1 further includes a suction nozzle 13, a metal wand 15 and a suction tool 11 including a handle 17. The handle 17 of the suction tool 11 is connected to the flexible suction hose 21 of the vacuum cleaner 1 by the first joint 19, and the suction hose 21 is detachably connected to the suction port 25 of the housing 3 by the second joint 23. The suction port 25 opens to a dust container 27 of the vacuum cleaner 1, and the dust container 27 is connected to the suction unit 9 via a filter 29. In operation, the suction unit 9 generates a partial vacuum in the dust container 27, the suction hose 21 and the suction tool 11, and as a result, dust particles on the surface 7 are sucked by the suction nozzle of the suction tool 11. 13 and the suction hose 21 are sucked into the dust container 27. As shown in FIG. 1, the handle 17 carries the control means 31 for the suction unit 9 and allows the user of the vacuum cleaner 1 to adjust the suction power of the suction unit 9. The control means 31 is composed of, for example, a variable resistor not shown in FIG. 1, and can be controlled by the slide control member 33. As shown in FIG. 2, the control means 31 uses the two electric conductors 35a and 35b arranged in two ducts 37a and 37b formed in the jacket of the suction hose 21 so as to be diagonally opposed to each other, and the suction unit 9 is provided. To be electrically connectable to. Further, as shown in FIG. 2, the first joint 19 connecting the handle 17 to the suction hose 21 includes a tubular first joint member 39 attached to the handle 17 and a tubular second joint member attached to the suction hose 21. And 41. The joint members 39, 41 of the first joint member 19 allow relative rotation about a rotation axis 43 of the joint member 19 which coincides with the common central axis of the tubular joint members 39, 41. The operability is improved because the joint members 39 and 41 can rotate relative to each other. FIG. 3 shows a cross section of the joint members 39 and 41 of the first joint 19. As shown in FIGS. 2 and 3, the second joint member 41 has a cylindrical union 45 having a central axis that coincides with the rotation axis 43. This union 45 is connected to the end 49 of the suction hose 21. A flexible plastic sleeve 51 is fitted around the end 49 of the suction hose 21, and the sleeve 51 is provided with a cutout 53 and an inclined locking projection 55. Each of the protrusions 55 is surrounded by a C-shaped cutout 54, which allows it to bend radially with respect to the axis of rotation 43 with respect to the sleeve 51. In the assembly shown in FIG. 2, the union 54 and the sleeve 51 can rotate relative to each other about the axis of rotation, and the sleeve 51 can slide axially on the suction hose 21 to the annular stop 59 of the union 45. The first joint member 39 has a bush 61 having an inner diameter corresponding to the outer diameter of the sleeve 51. In the assembly shown in FIG. 3 in which the two joint members 39, 41 are connected to each other, the locking projection 55 of the sleeve 51 engages with the opening 63 of the bush 61, and as a result, the sleeve 51 becomes the first joint member. The movement in the axial direction and the relative rotation with respect to 39 are prevented. At this time, the union 45 of the second joint member 41 is prevented from moving in the axial direction without clearance between the sleeve 51 and the other annular stopper 64 of the bush 61 of the first joint member 39. As a result, the second joint member 41 is prevented from moving in the axial direction with respect to the first joint member 39, and the joint members 39, 41 can relatively rotate around the rotation axis 43. The first joint 19 having the joint members 39, 41, the locking projection 55, and the opening 63 may permanently connect the handle 17 to the suction hose 21. Further, the first joint 19 may be configured as a detachable joint. At this time, the first joint 19 is provided with, for example, one flexible locking protrusion 55 that engages with one opening 63, bends one locking protrusion 55 in the direction of the rotation axis 43, and then the joint member. By separating 39 and 41, the user of the vacuum cleaner 1 can separate the handle 17 and the suction hose 21. A first annular groove 67 and a second annular groove 69, which are concentric with the rotation axis 43, are formed on the outer wall of the union 45, and positioning frames for the first ring-shaped electrical contact 71 and the second ring-shaped electrical contact 73, respectively. And As shown in FIGS. 2 and 3, each of the ring-shaped electrical contacts 71, 73 is formed of a phosphor bronze spiral spring 75, 77 in an annular groove 67, 69 as described below. The spiral springs 75, 77 are radially expanded with respect to the axis of rotation 43 and, in connection with this expansion, are retained in the grooves 67, 69 by the radially directed elastic pretensions present in the spiral springs 75, 77. To do. As shown in FIG. 2, the electric conductor 35a of the suction hose 21 is electrically connected to the first ring-shaped electric contact 71 of the second joint member 41, and the electric conductor 35b is electrically connected to the second ring-shaped electric contact 73. Connect to. As shown in FIG. 2, the duct 37a for the electric conductor 35a terminates in the second annular groove 69 and the slot 79 formed in the raised portion 81 between the first and second annular grooves 67, 69. The slot 79 communicates with the hook-shaped slot 83 of the first annular groove 67, and one end of the conductor 35 a is formed in the spiral spring 75 and the slot 67 under the action of the elastic pretension of the spiral spring 75. Clamp between the jagged ridges. The duct 37 for the electrical conductor 35b terminates in the hook-shaped slot 87 of the second annular groove 69 and, under the action of the elastic pretension of the spiral spring 77, one end of the electrical conductor 35b is screwed into the spiral spring 77. And a large number of jagged ridges 85 formed in the second annular groove 69. Further, as shown in FIGS. 2 and 3, the bush 61 of the first joint member 39 is provided with a first opening 91 and a second opening 93. The first electric contact 95 of the joint member 39 is arranged in the first opening 93, and the second electric contact 97 of the joint member 39 is arranged in the second opening 93. Each of the electrical contacts 95, 97 has a phosphor bronze flexible strip 99, 101. As shown in FIG. 3, the protrusion 99 of the first electrical contact 95 is pretensioned toward the first ring-shaped electrical contact 71 of the second joint member 41, and the second electrical contact 97 is the second joint. Pretensioning is applied to the second ring-shaped electrical contact 73 of the member 41. This pretension of the projections 99, 101 produces a suitable contact force between the electrical contacts 95, 97 of the first joint member 39 and the electrical contacts 71, 73 of the second joint member 41. The strip-shaped electric conductors 103a and 103b connect the projecting pieces 99 and 101 to the control means 31 in the handle 17, and the strip-shaped conductors 103a and 103b respectively penetrate the ducts 105a and 105b of the handle 17. The control means 31 in the handle 17 includes strip-shaped conductors 103a and 103b, electric contacts 95 and 97 of the first joint member 39, ring-shaped electric contacts 71 and 73 of the second joint member 41, and electric conductors in the suction hose 21. It is electrically connected to the suction unit 9 via 35a and 35b. Since the ring-shaped electrical contacts 71, 73 are arranged concentrically with respect to the rotation axis 43, even when the joint members 39, 41 of the first joint 19 relatively rotate during use of the vacuum cleaner 1, The electric contacts 95, 97 of the joint member 39 maintain the contact state with the ring-shaped electric contacts 71, 73 of the second joint member 41. This allows relative rotation between the joint members 39, 41 around the axis of rotation 43 without restriction. FIG. 4 a shows the state of the union 45 of the second joint member 41 and the spiral spring 77 of the second ring-shaped electrical contact 73 before the first joint 19 is assembled. The second annular groove 69 of the union 45, which constitutes the ring-shaped positioning frame for the ring-shaped electrical contact 73, has an outer diameter D 1 larger than the diameter D 2 of the unloaded spiral spring 77 before the joint 19 is assembled. Have. In the illustrated embodiment, D 1 is about 40 mm, D 2 is about 30 mm, and the wire diameter of the phosphor bronze spiral spring 77 is about 0.6 mm. FIG. 4 b shows a spreading tool 107 which fits the spiral spring 77 into the groove 69 of the union 45. The spreading tool 107 has a plurality of, for example, three or four pins 109 which are parallel to each other and whose distance from each other can be adjusted. A spiral spring 77 is placed around the pins 109 of the expansion tool 107, after which the distance between the pins is increased to increase the diameter of the spiral spring 77 and elastically deform the spiral spring. When the diameter of the deformed spiral spring 77 becomes larger than the diameter D 1 , the spiral spring 77 is arranged around the groove 69, and then the expanding tool 107 is taken out to engage the spiral spring 77 with the groove 69. The diameter D 1 of the groove 69 is larger than the diameter D 2 of the unloaded spiral spring 77, so that the spiral spring 77 has elastic pretension when in the groove 69. This pretension is directed radially with respect to the axis of rotation 43, so that the helical spring 77 is retained in the groove 69 by the pretension. Since the spiral spring 77 can be easily mounted in the groove 69 by the expansion tool 107, the union 45 of the second joint member 41 does not need to be disassembled when mounting the spiral spring 77. The union 45 of the second joint member 41 can be manufactured as a single integral piece, for example by an injection molding process, thus reducing the number of parts to be assembled as the first joint 19. Since the elastic pre-tension in the spiral springs 75, 77 is also used as a clamping force for the ends of the electrical conductors 35a, 35b, the first joint 19 provides another means for attaching the conductors 35a, 35b to the spiral springs 75, 77. It is not necessary, so that the number of parts to be assembled as the first joint 19 can be reduced. The second fitting 23 connecting the suction hose 21 to the suction port 25 of the housing 3 can be of similar construction to the first fitting 19 and will therefore not be described in detail. However, as described above, the suction hose 21 is detachably connected to the suction port 25, so that the second joint 23 is provided with only one locking protrusion 55 to separate the suction hose 21 from the suction port 25. To do so, the user of the vacuum cleaner 1 is allowed to bend the locking projection 55 toward the rotation axis of the second joint 23. Each of the ring-shaped electrical contacts 71, 73 of the above-mentioned joints 19, 23 is constituted by a spiral spring 75, 77. However, instead of the spiral springs 75, 77, other elastically deformable ring-shaped electrical contacts can be provided. For example, it may be a bent strip as a cylindrical sleeve. In the unloaded state, before attachment to the locating frame, such a sleeve has a diameter smaller than that of the locating frame and the ends of the strips overlap each other. The length of the strip is such that the ends of the strip abut each other when the strip is fitted into the positioning frame. In the above description, the embodiment in which the joints 19 and 23 according to the present invention are used for the vacuum cleaner 1 has been described. However, such fittings can also be used in other devices. For example, it can be used as a fixture for lighting, the first joint member is attached to a base portion of the fixture for lighting, the second joint member is attached to a part of the fixture for lighting such as a lamp socket, and the base of the fixture for lighting is attached. Allow to rotate against. The joint according to the invention can also be used, for example, in a winder for an electric cord, in which a first joint member is attached to a part of the cord winder so that it can be rotated relative to the base on which the electric cord is to be wound. Each of the couplings 19, 23 described above has two ring-shaped electrical contacts 71, 73 capable of contacting the two electrical contacts 95, 97. However, the coupling according to the invention can also be provided with a different number of electrical contacts, for example three or more electrical contacts. In the joints 19 and 23 described above, the electrical connection between the ring-shaped electrical contacts 71 and 73 and the electrical conductors 35a and 35b is clamped under the elastic pretension of the ring-shaped electrical contacts 71 and 73. Is gained by However, the electrical connection between the conductors 35a, 35b and the ring-shaped electrical contacts 71, 73 can also be made in different ways, for example by soldering known per se.
