Description

【０００１】
【産業上の利用分野】
本発明は、ハンドルを手動で押すことで掃除用横軸ブラシを回転させ、回転する掃除用横軸ブラシにより集塵ボックスにごみや塵埃等を集める手動式掃除機に係るものである。
【０００２】
【従来技術】
従来、左右一対の走行車輪および走行車輪を設けた本体ケースを前側のケースと、後側のケースとに分割形成し、後側のケースには掃除用横軸ブラシを設け、前側ケース全体を集塵ボックスに形成し、前記掃除用横軸ブラシは後側車輪に摺接する受動回転体により回転するように構成し、掃除用横軸ブラシは本体ケース全体を前進させると正回転し、本体ケース全体を後進させると逆回転しながら競り上がるようにした構成は公知である（特許文献１）。

【０００４】
【発明が解決しようとする課題】
前記公知例は、前後に本体ケースを分割し、分割したケースのうち前側ケース全体を集塵ボックスに構成しているため、ケースの下方を覆う底板の面積が大きくなり、重量が重いという課題がある。また、前後に分割したケースを連結固定する連結構成も堅牢である必要があり、その分重量は嵩むという課題がある。
また、公知例は、走行車輪の側面に当接するＶ溝受動輪により掃除用横軸ブラシに回転を伝達しているが、この伝達機構に課題がある。
即ち、公知例の伝達機構では、摩擦伝達のため、伝達ロスが大きい。しかも、掃除用横軸ブラシは本体ケースが後進状態のときは斜め前方に上動する構成のため、例え前進状態でも、掃除用横軸ブラシの回転負荷が大きくなると、後進状態のように斜め前方に逃げることになり、伝達ロスが生じる。
また、公知例の伝達構成では、本体ケースが後進状態のとき、掃除用横軸ブラシは停止せずに逆転するので床上の塵埃等を飛散させるという課題もある。
また、そもそも、掃除用横軸ブラシのブラシ横軸は斜めの長孔を自由に上下する構成のため、掃除用横軸ブラシの高さ調節はできない。
しかして、全体の構成を工夫すると、本体ケース全体の軽量化が図れて操作性を向上させ、掃除用横軸ブラシへの伝達機構を工夫すると、回転伝達ロスを最小限にすると共に、本体ケースの後進時の不要な掃除用横軸ブラシの逆転を防止でき、作業性を向上させられる。
本願は、全体を軽量にし、掃除用横軸ブラシを逆転させずに確実に回転を伝達させるようにしたものである。
【０００５】
【発明の目的】
本体ケースの軽量化、掃除用横軸ブラシの逆転防止、移動中の掃除用横軸ブラシの回転停止、塵埃等の飛散の防止、旋回性能および直進走行性能の向上、操作性の向上、作業性の向上。
【０００６】
【課題を解決するための手段】
本発明は、左右一対の走行車輪２および走行車輪３を設けた本体ケース１に走行車輪３の回転により回転する掃除用横軸ブラシ６を設け、該掃除用横軸ブラシ６の前側に該掃除用横軸ブラシ６が掃いた塵埃等を回収する集塵ボックス２２を設け、前記本体ケース１は下面を開放した一体箱形状に形成し、前記掃除用横軸ブラシ６の前側の本体ケース１には開口部２４を形成し、該開口部２４には上方より前記集塵ボックス２２のみを着脱自在となるように設け、前記後側走行車輪３の後側車軸５の左右両側に出力歯車１１を設け、前記掃除用横軸ブラシ６のブラシ横軸７には前記出力歯車１１に常時噛合う受動歯車１０を設け、前記受動歯車１０または前記出力歯車１１は一方向回転のみ伝達し他方向回転は空転させるように構成し、前記本体ケース１の左右両側には前記後側車軸５に基部を回動自在に設けた高さ調節アーム１５を設け、該高さ調節アーム１５には前記ブラシ横軸７を軸装し、該ブラシ横軸７は前記本体ケース１の側板４に形成した前記後側車軸５を中心とする円弧長孔１２に挿通し、前記高さ調節アーム１５の先端側には調節ボルト１６が選択係合する係合孔１７を形成し、調節ボルト１６を側板４に螺合させて掃除用横軸ブラシ６の高さ調節自在に構成し、前記掃除用横軸ブラシ６の前側であって前記集塵ボックス２２の後側開口部２６の後側には前記掃除用横軸ブラシ６が掃く塵埃等を前記集塵ボックス２２に誘導する後下がりの塵埃等誘導体３５を設け、該塵埃等誘導体３５はアーム３７の下部に取付け、該アーム３７の上下中間部は軸３８により本体ケース１に取付け、前記アーム３７の上部にはロッド３９の前端を軸止し、該ロッド３９の後端はブラシ横軸７に設けた回転体４０の軸心を外した偏心位置に軸止し、前記アーム３７とロッド３９と回転体４０によりリンク機構を構成し、前記塵埃等誘導体３５は、前記掃除用横軸ブラシ６の回転により軸３８中心に先端が上下動するようにし、塵埃等誘導体３５の下面と床面の間に溜った塵埃等が塵埃等誘導体３５の下縁を通過するようにすると共に、塵埃等誘導体３５は、掃除用横軸ブラシ６の一回転に対して一回上下するように構成した手動式掃除機としたものである。
本発明は、前記走行車輪２は方向自在なキャスター輪により構成し、前記本体ケース１の後部には接地すると後側走行車輪３を床面より上動させる移動用車輪４８を、接地位置と退避位置の間移動自在に設けた手動式掃除機としたものである。
【０００７】
【実施例】
本発明の実施例を図面により説明すると、１は掃除機の本体ケースであり、平面視矩形形状を呈し、下面側は略開放空間に形成している。
本体ケース１には前後に走行車輪２、３を設ける。前側走行車輪２は左右一対設けられ、所謂キャスター輪に形成し、本体ケース１の走行方向の変換を容易にしている。後側走行車輪３は本体ケース１の左右側板４に後側車軸５により夫々軸装する。実施例の後側車軸５は左右に分割して左右側板４に取付けることで、軽量化を図っているが、本体ケース１を貫通させてもよい。
後側車軸５の前側位置の本体ケース１には掃除用横軸ブラシ６を設ける。掃除用横軸ブラシ６はブラシ横軸７により側板４に着脱自在に軸装する。左右両側のブラシ横軸７には受動歯車１０を設け、各受動歯車１０は後側車軸５に設けた出力歯車１１に常時噛み合わせる。出力歯車１１には公知のラチエット機構Ｌを内蔵し、ラチエット機構Ｌは後側車軸５からの一方向回転は出力歯車１１に伝達するが、出力歯車１１から後側車軸５への逆回転は空転させるように構成している。
【０００８】
そのため、出力歯車１１は、本体ケース１を手動により前進走行させると、後側走行車輪３の回転により掃除用横軸ブラシ６を回転させるが、本体ケース１を後進させたときのバック回転はブラシ横軸７に伝達せず、掃除用横軸ブラシ６の逆転を防止する。
なお、受動歯車１０にラチエット機構Ｌを設けてもよい。
【０００９】
しかして、掃除用横軸ブラシ６は高さ調節自在に構成する。前記側板４には後側車軸５を中心とする円弧長孔１２を設け、円弧長孔１２よりブラシ横軸７の両端を突出させ、円弧長孔１２より突出したブラシ横軸７は高さ調節アーム１５の前後中間部に取付ける。高さ調節アーム１５の基部は後側車軸５に回動自在に軸着し、高さ調節アーム１５の先端側には調節ボルト１６を取付ける。実施例では、調節ボルト１６の先端を「浅」、「中」、「深」の夫々の位置の高さ調節アーム１５に形成した係合孔１７に選択係合させて側板４に螺合させ、掃除用横軸ブラシ６の高さを保持している。
高さ調節アーム１５の先端は先鋭形状部１８に形成し、先鋭形状部１８は側板４に設けた表示部１９を指示するようにし、掃除用横軸ブラシ６の高さを表示するようにしている。
なお、ブラシ横軸７の取付構成は、ブラシ横軸７を中空筒軸により形成し、ブラシ横軸７の両端を高さ調節アーム１５に回転自在に設けた取付軸２０に着脱自在に嵌合固定させて取付けると、掃除用横軸ブラシ６の交換は伝動機構を分解しないで行えて容易になり、好適である。
【００１０】
しかして、掃除用横軸ブラシ６の前側の本体ケース１には掃除用横軸ブラシ６が掃くゴミや塵埃等を回収する集塵ボックス２２を設ける。集塵ボックス２２は、集塵ボックス２２は後側のみ開放した箱形状に形成し、集塵ボックス２２の上面に設けた把手２３を持って本体ケース１の上面前側に設けた開口部２４に上方から嵌合させる。
したがって、本体ケース１は下面を開放した一体箱形状に形成している。
この場合、集塵ボックス２２はその上板２５の周縁を開口部２４に設けた上板支持部２５ａに上方より係合させて取付ける。集塵ボックス２２の後側開口部２６は掃除用横軸ブラシ６の前側に臨ませ、後側開口部２６から回転する掃除用横軸ブラシ６により塵埃等を掃き入れ、一定量の塵埃等が回収されたら、本体ケース１の開口部２４から引き抜いて中の塵埃等を廃棄する。集塵ボックス２２の底板２７はその後端縁２８を上側にやや折り曲げ、回収した塵埃等がこぼれるのを防止する。
２９は掃除用横軸ブラシ６の左右両側に設けたサイドカバーである。
【００１１】
しかして、後側開口部２６と掃除用横軸ブラシ６との間には後下がりの塵埃等誘導体３５を設ける。塵埃等誘導体３５はゴム等の弾性部材により形成し、塵埃等誘導体３５は先端を床面に摺接または近接させ、「塵取り」のように掃除用横軸ブラシ６が掃き上げる塵埃等を集塵ボックス２２の後側開口部２６に誘導する。塵埃等誘導体３５は板状に後側開口部２６の左右幅と同じかやや大きく形成し、塵埃等誘導体３５はアーム３７の下部に取付け、アーム３７の上下中間部は軸３８により本体ケース１に取付け、アーム３７の上部にはロッド３９の前端を軸止し、ロッド３９の後端はブラシ横軸７に設けた回転体４０の軸心を外した偏心位置に軸止し、アーム３７とロッド３９と回転体４０によりリンク機構を構成している。
塵埃等誘導体３５は、掃除用横軸ブラシ６の回転により軸３８中心に先端が上下（振動）するようにし、塵埃等誘導体３５の下面と床面の間に溜った塵埃等が塵埃等誘導体３５の下縁を通過するようにしている。
この場合、塵埃等誘導体３５は、掃除用横軸ブラシ６の一回転に対して一回上下するように、前記塵埃等誘導体３５の作動用のリンク機構を構成している。
【００１２】
しかして、本体ケース１の前側の左右何れか一側には縦軸回転ブラシ４１を設ける。縦軸回転ブラシ４１はステー４２により本体ケース１に回転自在に取付け、縦軸回転ブラシ４１の軸４３には受動回転体４４を設け、受動回転体４４は前記ブラシ横軸７に設けた出力回転体４５との間にベルト４６を掛け回す。
しかして、本体ケース１の後部には、一個の移動用車輪４８を設ける。移動用車輪４８は取付アーム４９の先端に取付け、取付アーム４９は横軸５０により回動自在に本体ケース１に取付け、取付アーム４９を上方回動させると、移動用車輪４８は格納状態となる。
取付アーム４９は下方回動させてストッパ５１に当接させると、移動用車輪４８が接地して移動状態になり、本体ケース１の後部を上動させて後側走行車輪３を上方移動させ、移動用車輪４８と前側走行車輪２により走行して移動する。
そのため、移動中は後側走行車輪３が回転しないので、掃除用横軸ブラシ６も回転せず、移動中に掃除用横軸ブラシ６の回転を停止させられる。
５２はハンドルであり、ハンドル５２を押し引きして本体ケース１を移動させる。
【００１３】
【作用】
次に作用を述べる。
本発明の実施例を図面により説明すると、ハンドル５２により本体ケース１を押すと、走行車輪２、３が回転し、本体ケース１は前進する。後側走行車輪３が回転すると、後側走行車輪３の回転が後側車軸５の出力歯車１１を介して受動歯車１０に伝達される。
出力歯車１１は、後側走行車輪３からの前進方向回転のみをブラシ横軸７に伝達するから、ブラシ横軸７は掃除用横軸ブラシ６を回転させ、回転する掃除用横軸ブラシ６は床上の塵埃等を集塵ボックス２２の後側開口部２６に向けて掃き飛ばし、掃き飛ばされた塵埃等は集塵ボックス２２に収容され、所定量溜ると、集塵ボックス２２を外して廃棄すればよい。
【００１４】
しかして、本体ケース１は、下面を開放した一体箱型形状に形成し、本体ケース１に所定容積を有する集塵ボックス２２を装着しているから、本体ケース１全体を軽量に構成でき、操作性を向上させる。
また、後側走行車輪３はブラシ横軸７の左右両側の受動歯車１０を回転させ、夫々の後側走行車輪３に回転負荷を掛けるので、本体ケース１の直進性を向上させる。
即ち、左右の一方の後側走行車輪３の後側車軸５に出力歯車１１を設けたのでは、出力歯車１１を設けた側の後側車軸５にブレーキが掛かったのと同様になり、出力歯車１１を設けた側に向けて本体ケース１は旋回しようとし、直進走行が円滑でなくなるが、本願では左右の後側車軸５に出力歯車１１を設けているので、直進性を向上させる。
【００１５】
この場合、出力歯車１１または受動歯車１０には公知のラチエット機構Ｌを内蔵し、後側車軸５からの一方向回転（前進回転）はブラシ横軸７に伝達するが、ブラシ横軸７から後側車軸５への逆回転は空転させるように構成しているから、本体ケース１を後進させたときに掃除用横軸ブラシ６が逆転するのを防止するのみならず、左右旋回するとき、左右の後側走行車輪３に回転差が生じてもラチエット機構Ｌにより内側の出力歯車１１または受動歯車１０が空転することで回転差を吸収し、円滑に旋回する。
【００１６】
しかして、掃除用横軸ブラシ６は、本体ケース１の側板４の円弧長孔１２にブラシ横軸７を挿通し、円弧長孔１２より突出したブラシ横軸７の左右両側は高さ調節アーム１５の前後中間部に回転のみ自在に取付け、高さ調節アーム１５の基部は後側車軸５に回動自在に軸装し、高さ調節アーム１５の先端側には調節ボルト１６を取付けているから、調節ボルト１６を弛めて、高さ調節アーム１５を後側車軸５中心に上下回動させると、掃除用横軸ブラシ６の先端高さを調節できる。
【００１７】
この場合、高さ調節アーム１５は後側車軸５中心に回動するため、後側車軸５の出力歯車１１とブラシ横軸７の受動歯車１０は常時噛み合ったままであり、掃除用横軸ブラシ６の伝動機構に何らの影響を与えずに高さ調節でき、高さ調節は頗る容易にできる。
しかして、掃除用横軸ブラシ６の高さ調節は、床面を基準に、床面より掃除用横軸ブラシ６の下端が下方になるに従い「浅（約４．５ｍｍ）」、「中（約１０ｍｍ）」、「深（約１３．５ｍｍ）」となり、深く位置させると、床面より下方に位置することになって、その分掃除用横軸ブラシ６の先端が弾性変形して曲がり、掃出作用が強くなる。
【００１８】
即ち、例えば、事務所等の室内や屋内外のコンクリート等の平坦な床面では掃除用横軸ブラシ６の先端を「浅」に合わせ、アスファルトの駐車場のように凹凸のある床面では「深（約１３．５ｍｍ）」に合わせるとよく、種々の状況に対応する。
また、掃除用横軸ブラシ６の先端が摩滅したときも、高さ調節により掃除用横軸ブラシ６の高さを低くすることで、対応でき、長時間の使用を可能にする。
【００１９】
しかして、掃除用横軸ブラシ６の前側には後側に後側開口部２６を設けた集塵ボックス２２を設けているから、掃除用横軸ブラシ６が図において時計回転すると塵埃等は後側開口部２６より集塵ボックス２２内に入る。
この場合、集塵ボックス２２の底板２７は、床面に干渉しないように、床面より所定間隔をおいた上方に設け、底板２７の後端縁２８と掃除用横軸ブラシ６との間には後下がりの塵埃等誘導体３５を設けているから、塵埃等誘導体３５は「塵取り」のように掃除用横軸ブラシ６が掃き上げる塵埃等を集塵ボックス２２の後側開口部２６に誘導する。
【００２０】
この場合、塵埃等誘導体３５はゴム等の弾性部材により形成し、塵埃等誘導体３５は先端を床面に可及的に接近させると、塵埃等の誘導が円滑になるが、本体ケース１の前進に伴って、塵埃等誘導体３５の下面側に塵埃等が溜ることになる。
本願では、塵埃等誘導体３５は、その下端を本体ケース１の走行中に定期的に上下するように構成しているから、塵埃等誘導体３５が下方位置のときは塵埃等を集塵ボックス２２に誘導し、上動すると床上面に溜った塵埃等を通過させ、掃除用横軸ブラシ６に集塵ボックス２２に向けて掃き入れる。
即ち、本体ケース１の走行により後側走行車輪３が回転し、出力歯車１１と受動歯車１０を介してブラシ横軸７を回転させ、ブラシ横軸７の回転により回転体４０が回転し、回転体４０の回転運動をロッド３９とアーム３７により塵埃等誘導体３５の下端の上下運動に変換し、塵埃等誘導体３５の下端を本体ケース１の走行中に定期的に上下させる。
【００２１】
しかして、本体ケース１の後部には接地すると後側走行車輪３を床面より上動させる移動用車輪４８を設けているから、取付アーム４９を下方回動させてストッパ５１に当接させて、移動用車輪４８を接地させると、本体ケース１の後部を上動させて後側走行車輪３を床面より離して移動状態になり、移動用車輪４８と前側走行車輪２により走行して移動する。
したがって、移動中は後側走行車輪３が回転しないので、掃除用横軸ブラシ６も回転せず、移動中に掃除用横軸ブラシ６の回転を停止させられ、単に取付アーム４９により上下回動させる構成により、掃除用横軸ブラシ６の回転伝達を入り切りさせられる。
【００２２】
【効果】
請求項１の発明では、集塵ボックス２２を作業性の犠牲とならない範囲で小型にしたので、本体ケース１は下面を開放した一体箱形状に形成でき、集塵ボックス２２の底板２７の面積を小にして軽量化が図れ、取り回しが良好となって操作性および作業性を向上させることができ、後側走行車輪３の後側車軸５と掃除用横軸ブラシ６のブラシ横軸７とは受動歯車１０と出力歯車１１により回転伝達するので、伝達ロスを最小限にすると共に、後進時の掃除用横軸ブラシ６の逆転を防止して塵埃等の飛散を防止でき、後側走行車輪３と掃除用横軸ブラシ６との伝達機構である受動歯車１０と出力歯車１１の位置関係を変えずに、掃除用横軸ブラシ６の高さ調節でき、高さ調節作業を頗る容易にでき、掃除用横軸ブラシ６の高さ調節を可能にすることで、塵埃等回収効率を向上させ、また、掃除用横軸ブラシ６の摩耗にも対応でき、集塵ボックス２２への塵埃等の掃き入れを確実にしつつ、塵埃等誘導体３５の存在による掃除用横軸ブラシ６の掃き残しを抑制できる。
請求項２の発明では、移動中は後側走行車輪３が回転しないので、掃除用横軸ブラシ６も回転せず、移動中の掃除用横軸ブラシ６の回転を停止させることができる。

[0007]
【Example】
An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a main body case of a vacuum cleaner, which has a rectangular shape in plan view and has a lower surface formed in a substantially open space.
The main body case 1 is provided with traveling wheels 2 and 3 at the front and rear. A pair of left and right front traveling wheels 2 are provided and are formed as so-called caster wheels to facilitate conversion of the traveling direction of the main body case 1. The rear traveling wheels 3 are respectively mounted on the left and right side plates 4 of the main body case 1 by the rear axle 5.

[0010]
Therefore, the main body case 1 on the front side of the cleaning horizontal axis brush 6 is provided with a dust collection box 22 that collects dust, dust and the like swept by the cleaning horizontal axis brush 6. The dust collection box 22 is formed in a box shape in which the dust collection box 22 is opened only on the rear side, and has a handle 23 provided on the upper surface of the dust collection box 22 and is positioned above the opening 24 provided on the front upper surface of the main body case 1. Fit from.
Therefore, the main body case 1 is formed in an integral box shape with the lower surface opened.
In this case, the dust collection box 22 is attached by engaging the periphery of the upper plate 25 with the upper plate support portion 25a provided in the opening 24 from above. The rear opening 26 of the dust collection box 22 faces the front side of the cleaning horizontal axis brush 6, and the cleaning horizontal axis brush 6 that rotates from the rear opening 26 sweeps away dust and the like so that a certain amount of dust is generated. When collected, it is pulled out from the opening 24 of the main body case 1 to discard the dust and the like. The bottom plate 27 of the dust collection box 22 slightly bends the rear edge 28 upward to prevent the collected dust and the like from spilling out.
Reference numeral 29 denotes side covers provided on the left and right sides of the cleaning horizontal axis brush 6.
[0011]
Accordingly, a dust-reducing material 35 such as dust that falls rearward is provided between the rear opening 26 and the cleaning horizontal brush 6. The dust etc. derivative 35 is formed of an elastic member such as rubber, and the dust etc. derivative 35 is brought into sliding contact with or close to the floor surface to collect dust etc. that the cleaning horizontal axis brush 6 sweeps up like “dust removal”. Guide to the rear opening 26 of the dust box 22. The dust derivative 35 is formed in a plate shape that is slightly larger than the left and right width of the rear opening 26. The dust derivative 35 is attached to the lower part of the arm 37, and the upper and lower intermediate parts of the arm 37 are attached to the main body case 1 by the shaft 38. The front end of the rod 39 is fixed to the upper part of the arm 37, and the rear end of the rod 39 is fixed at an eccentric position where the axis of the rotating body 40 provided on the brush horizontal shaft 7 is removed. 39 and the rotating body 40 constitute a link mechanism.
The dust etc. derivative 35 has its tip vertically moved (vibrated) around the shaft 38 by the rotation of the cleaning horizontal axis brush 6, and the dust etc. accumulated between the lower surface of the dust etc. derivative 35 and the floor surface is the dust derivative 35. It passes through the lower edge.
In this case, the dust etc. derivative 35 constitutes a link mechanism for operating the dust etc. derivative 35 so as to move up and down once with respect to one rotation of the cleaning horizontal axis brush 6.
[0012]
Therefore, a vertical axis rotating brush 41 is provided on either the left or right side of the front side of the main body case 1. The vertical rotation brush 41 is rotatably attached to the main body case 1 by a stay 42. A passive rotation body 44 is provided on the shaft 43 of the vertical rotation brush 41. The passive rotation body 44 is an output rotation provided on the brush horizontal shaft 7. A belt 46 is hung around the body 45.
Thus, one moving wheel 48 is provided at the rear of the main body case 1. The movement wheel 48 is attached to the tip of the attachment arm 49, the attachment arm 49 is attached to the main body case 1 so as to be rotatable by the horizontal shaft 50, and when the attachment arm 49 is turned upward, the movement wheel 48 is retracted. .
When the mounting arm 49 is rotated downward and brought into contact with the stopper 51, the moving wheel 48 comes into contact with the stopper 51, and the rear wheel 3 is moved upward by moving the rear portion of the main body case 1 upward. The vehicle travels and moves with the moving wheel 48 and the front traveling wheel 2.
Therefore, since the rear traveling wheel 3 does not rotate during movement, the cleaning horizontal axis brush 6 does not rotate, and rotation of the cleaning horizontal axis brush 6 can be stopped during movement.
Reference numeral 52 denotes a handle that pushes and pulls the handle 52 to move the main body case 1.
[0013]
[Action]
Next, the operation will be described.
The embodiment of the present invention will be described with reference to the drawings. When the main body case 1 is pushed by the handle 52, the traveling wheels 2 and 3 rotate, and the main body case 1 moves forward. When the rear traveling wheel 3 rotates, the rotation of the rear traveling wheel 3 is transmitted to the passive gear 10 via the output gear 11 of the rear axle 5.
Since the output gear 11 transmits only the forward rotation from the rear traveling wheel 3 to the brush horizontal shaft 7, the brush horizontal shaft 7 rotates the cleaning horizontal shaft brush 6, and the rotating cleaning horizontal shaft brush 6 is rotated. Dust and the like on the floor are swept away toward the rear opening 26 of the dust collection box 22, and the dust that has been swept away is accommodated in the dust collection box 22, and when a predetermined amount accumulates, the dust collection box 22 is removed and discarded. That's fine.
[0014]
Thus, the main body case 1 is formed in an integral box shape with the lower surface open, and the main body case 1 is equipped with a dust collection box 22 having a predetermined volume. Improve sexiness.
Further, since the rear traveling wheel 3 rotates the passive gears 10 on both the left and right sides of the brush horizontal shaft 7 and applies a rotational load to each rear traveling wheel 3, the straight traveling performance of the main body case 1 is improved.
That is, the provision of the output gear 11 on the rear axle 5 of one of the left and right rear traveling wheels 3 is the same as that the brake is applied to the rear axle 5 on the side where the output gear 11 is provided. Although the main body case 1 tries to turn toward the side where the gear 11 is provided and the straight traveling is not smooth, in the present application, since the output gear 11 is provided on the left and right rear axles 5, the straight traveling performance is improved.
[0015]
In this case, the output gear 11 or the passive gear 10 incorporates a known ratchet mechanism L, and unidirectional rotation (forward rotation) from the rear axle 5 is transmitted to the brush horizontal shaft 7. Since the reverse rotation to the side axle 5 is configured to idle, not only the cleaning horizontal shaft brush 6 is prevented from reversing when the main body case 1 is moved backward, but also when turning left and right, Even if a rotational difference occurs in the rear traveling wheel 3, the inner output gear 11 or the passive gear 10 rotates idly by the ratchet mechanism L to absorb the rotational difference and smoothly turn.
[0016]
Thus, the cleaning horizontal axis brush 6 has the brush horizontal axis 7 inserted into the circular arc long hole 12 of the side plate 4 of the main body case 1, and the left and right sides of the brush horizontal axis 7 protruding from the circular arc long hole 12 are height adjustment arms. The base of the height adjustment arm 15 is rotatably mounted on the rear axle 5 and an adjustment bolt 16 is attached to the front end side of the height adjustment arm 15. Therefore, if the adjustment bolt 16 is loosened and the height adjustment arm 15 is turned up and down around the rear axle 5, the tip height of the cleaning horizontal axis brush 6 can be adjusted.
[0017]
In this case, since the height adjusting arm 15 rotates about the rear axle 5, the output gear 11 of the rear axle 5 and the passive gear 10 of the brush horizontal shaft 7 are always engaged with each other, and the cleaning horizontal brush 6 The height can be adjusted without affecting the transmission mechanism, and the height can be adjusted easily.
Thus, the height of the cleaning horizontal axis brush 6 is adjusted based on the floor surface as “lower (about 4.5 mm)”, “middle ( About 10 mm) ”and“ depth (about 13.5 mm) ”, and when placed deeper, it is located below the floor surface, and the tip of the horizontal shaft brush 6 for cleaning is elastically deformed and bent accordingly. The sweeping action becomes stronger.
[0018]
That is, for example, on a flat floor surface such as indoor or outdoor concrete in an office or the like, the tip of the cleaning horizontal axis brush 6 is set to “shallow”, and on an uneven floor surface such as an asphalt parking lot, “ It can be adjusted to “depth (about 13.5 mm)”, which corresponds to various situations.
Further, even when the tip of the cleaning horizontal axis brush 6 is worn, it can be coped with by reducing the height of the cleaning horizontal axis brush 6 by adjusting the height, thereby enabling long-term use.
[0019]
Since the dust collecting box 22 having the rear opening 26 is provided on the rear side on the front side of the cleaning horizontal brush 6, when the cleaning horizontal brush 6 rotates clockwise in FIG. It enters the dust collection box 22 from the side opening 26.
In this case, the bottom plate 27 of the dust collection box 22 is provided above the floor surface so as not to interfere with the floor surface, and is provided between the rear edge 28 of the bottom plate 27 and the cleaning horizontal axis brush 6. Is provided with a dust lowering derivative 35, and the dust derivative 35 guides the dust or the like swept up by the cleaning horizontal axis brush 6 to the rear opening 26 of the dust collection box 22 like "dust removal". To do.
[0020]
In this case, the dust derivative 35 is formed of an elastic member such as rubber. When the tip of the dust derivative 35 is brought as close to the floor surface as possible, the guidance of the dust and the like is facilitated. As a result, dust or the like accumulates on the lower surface side of the dust or the like derivative 35.
In the present application, the dust etc. derivative 35 is configured such that the lower end thereof is periodically moved up and down while the main body case 1 is traveling. Therefore, when the dust etc. derivative 35 is in the lower position, the dust etc. is collected in the dust collection box 22. When it is guided and moved up, dust and the like accumulated on the upper surface of the floor are allowed to pass, and are swept into the cleaning horizontal axis brush 6 toward the dust collection box 22.
That is, the rear traveling wheel 3 is rotated by the traveling of the main body case 1, the brush horizontal shaft 7 is rotated through the output gear 11 and the passive gear 10, and the rotating body 40 is rotated by the rotation of the brush horizontal shaft 7. The rotational movement of the body 40 is converted into the vertical movement of the lower end of the dust etc. derivative 35 by the rod 39 and the arm 37, and the lower end of the dust etc. derivative 35 is periodically raised and lowered while the main body case 1 is traveling.
[0021]
Therefore, since a moving wheel 48 for moving the rear traveling wheel 3 upward from the floor surface is provided at the rear of the main body case 1, the mounting arm 49 is rotated downward to come into contact with the stopper 51. When the moving wheel 48 is grounded, the rear part of the main body case 1 is moved upward to move the rear traveling wheel 3 away from the floor, and the traveling wheel 48 and the front traveling wheel 2 travel and move. To do.
Accordingly, since the rear traveling wheel 3 does not rotate during movement, the cleaning horizontal axis brush 6 does not rotate, and the rotation of the cleaning horizontal axis brush 6 can be stopped during movement and is simply rotated up and down by the mounting arm 49. With this configuration, rotation transmission of the cleaning horizontal axis brush 6 can be turned on and off.
[0022]
【effect】
In the first aspect of the present invention, the dust collection box 22 is reduced in size so long as the workability is not sacrificed. Therefore, the main body case 1 can be formed in an integrated box shape with the lower surface open, and the area of the bottom plate 27 of the dust collection box 22 lighter Hakare in the small, the brush horizontal axis 7 of the side axles 5 and cleaning horizontal axis brush 6 after the maneuverability can be improved operability and workability becomes good, rear driving wheels 3 since the rotation transmission passive gear 10 by the output gear 11, while minimizing the transmission loss, it can prevent scattering of such dust to prevent reverse rotation of the cleaning horizontal axis brush 6 at the reverse, the rear driving wheel 3 Without changing the positional relationship between the passive gear 10 and the output gear 11 which is a transmission mechanism between the cleaning brush 6 and the horizontal brush 6 for cleaning, the height of the cleaning horizontal brush 6 can be adjusted, and the height adjustment work can be easily performed. Enables height adjustment of horizontal brush 6 for cleaning And in, to improve the dust collection efficiency, also it can handle the wear of the cleaning horizontal axis brush 6, while ensuring sweep in of dust or the like to the dust collecting box 22, the cleaning due to the presence of dust or the like derivative 35 It is possible to suppress the remaining sweep of the horizontal axis brush 6.
In the second aspect of the invention, since the rear traveling wheel 3 does not rotate during movement, the cleaning horizontal axis brush 6 does not rotate, and the rotation of the moving horizontal axis brush 6 during movement can be stopped.
