Description

本発明は、掃除機の床ノズルに関するもので、進行方向に制限手段例えば滑り板により前後が仕切られた吸引室を有し、吸引室の内部は場合によっては回転できるブラシが配置されている。   The present invention relates to a floor nozzle of a vacuum cleaner, and has a suction chamber whose front and rear are partitioned by a restricting means, for example, a sliding plate, in a traveling direction, and a brush that can rotate in some cases is disposed inside the suction chamber.

話題とする種類の床ノズルは既知である。例えば吸引室の前後に配置された滑り板の形状の制限手段は、とくに絨毯の床の作業に効果があり、この場合床ノズルは滑り板によって絨毯のけばに支えられ、密閉に近い吸引室の遮断を生ずる。この場合濃密なおよび／またはけばの高い絨毯床では吸引室に高い負圧を生じ、高い摩擦によって滑動力を上昇させる。この上昇した滑動力は掃除機の使用を困難にする。   The kind of floor nozzles of interest is known. For example, the means for restricting the shape of the sliding plate arranged in front of and behind the suction chamber is particularly effective for the work of the carpet floor. In this case, the floor nozzle is supported by the slip of the carpet by the sliding plate, and the suction chamber is close to sealing. Cause interruption. In this case, a dense and / or high carpet floor creates a high negative pressure in the suction chamber and increases the sliding force by high friction. This increased sliding force makes it difficult to use the vacuum cleaner.

上記に説明した技術の現状を考慮し、本発明の技術的課題は、話題とする種類の床ノズルを特に絨毯床の吸引作業の操作性に関して改善することである。   In view of the current state of the art described above, the technical problem of the present invention is to improve the floor nozzles of the kind discussed, especially with respect to the operability of the carpet floor suction operation.

この課題は先ず本質的に請求項１の対象物によって解決され、制限手段は部分的範囲にわたって垂直方向に移動することができ、制限手段は吸引ダクトに発生する負圧および／または吸引ノズルの前進および後進移動に関連して自動的に上昇することができることに重点を置いている。本発明による構成によって吸引室の負圧を最大値に限定する可能性が生まれる。この値は塵埃の吸引すなわち清掃効果を更に確実にするよう高く選定され、他方では使用者にとって滑動力が耐え得る範囲となるよう低く選定される。選定された制限手段の調整によって追加的に流入する空気は、絨毯の上を密着して滑るのでこの位置で絨毯のけばに付着している汚れは良好に吸引することができる。さらに上昇可能または下降可能な制限手段は、ほぼ垂直に移動することができる滑り板の方式に形成し、更にこのような有効空気滑り板または粗い汚れ用または洗浄空気用滑り板の幅は床ノズルの全体の幅より小さく選定し、作業する絨毯床の移動することができる制限手段の両側は、床板または滑り板などの隣接する移動することができない制限手段によって低く保持されることが好ましい。これに関連して制限手段または滑り板の移動することができる幅は５０ないし２００ｍｍが考えられる。制限手段によって吸引室に流入する空気の量は調整することができ、滑り板または制限手段の下側の角が清掃する床を閉じる完全に閉鎖された状態から、希望する清掃負荷または幾何学的な実情により制約される希望する最大の開口量まで調整できる。滑り板または垂直に移動することができる制限手段の下側の角は気密唇状体または一種の滑り板で形成すると好ましい。ここで上昇した制限手段によって設定された開口部は、粗い物体の受け入れ用として形成することができる。隙間からの塵埃受け入れの最適化に対し、大きな開口部は制限手段によって閉鎖し、制限手段は剛毛の帯のセグメントまたは気密唇状体から形成する。これに関し更に制限手段を下降方向に押し付けることが好ましい。更に吸入ノズル内にワイパ状の探索体を配置し、吸引室に侵入する基盤の一部区間特に吸引された絨毯の一部区間によってワイパ状の探索体は変位し、探索体の変位が制限手段の上昇を制御することを提案する。特に濃密な絨毯を吸引した場合、吸引室の負圧は絨毯または吸引室を下側からほぼ気密にする絨毯の一部区間が強く吸引されるほど高くなり、絨毯のけばは吸引室内に深く進入する。これによってワイパ状の探索体は打撃を受けて変位し、これによって吸引室の負圧の調整のため制限手段の上昇が行なわれる。吸引室の負圧はこれによって改善され小さな滑動力に調整される。これに関し更に探索体の変位反応しきい値が調節できるようにすると好都合である。この構成により負圧しきい値は調整できるようになり、これを超えてはじめて制限手段の上昇が負圧の調整のために実施される。有利な方法で探索体を吸引室に配置され、ワイパ状の変位することができるブラシとする。ブラシはこの場合吸引室の外側で、ブラシの回転軸と平行に調整された旋回軸の周りを移動することができ、旋回軸は同時にブラシの回転軸例えば歯付きベルトによって駆動されるブラシの電気モータの軸でもよい。吸引作業中に絨毯の一部区間が吸引室に吸引されると、これによってブラシは上昇する。この場合探索体として同時に機能するブラシは、反応しきい値の超過によって吸引室の負圧の調整のために制限手段を上昇させる。吸引室に作用する負圧自体は制限手段の上昇力に置き換えられる。吸引室に作用する負圧は常に測定することができる。予め規定したしきい値の超過により、制限手段が開放される。基本的に実施態様とは無関係に、制限手段の垂直方向への移動は測定された負圧に比例するか、または探索体の変位経路に比例する。また負圧を負圧ピストンに作用させ、制限手段に作用する作用手段の作用部品に強固に結合することもできる。これによって吸引室に発生した負圧により、移動することのできる制限手段の垂直方向の位置に誘導する機械的な解決法が実現される。上述の説明による解法の代替または組み合わせとして、吸引ノズルにワイパ状の探索体を設け、吸引ノズルの前進手動および後進移動に応じて傾かせることもできる。一般に粗い物体の取り入れは吸入移動の前進で行なわれ、一方比較的高い負圧を前提とした隙間からの吸引は前進および後進で使用される。本発明により吸引ノズルに設けられたワイパ状の探索体は、前進時の開口部を粗い物体の取り入れのため自動的に開放すなわち垂直方向に移動することができる制限手段を上昇させ、一方後進時には自動的に垂直方向に移動することができる制限手段によって形成されるシャッタを閉鎖する。これに関連する探索体は梃子状に形成され、基盤すなわち吸引する床の反対側の探索体の梃子区間は制限手段の移動を制御する。代わりに前進移動および後進移動の区別を、場合によってはローラまたはその他の一緒に回転する構成部品の回転方向の把握によって行なうこともできる。上記の制限手段に作用する作用手段は梃子の連結棒または荷重伝達鋼索でもよく、この場合探索体梃子区間に基づく荷重伝達鋼索の結合が、別の位置よりも制限手段の固定に近い位置とすることを提案する。基盤と共同作用する床ノズルの前進移動および後進移動の変化により傾くことができる梃子状の探索体は、その回転軸の過度の変位を調整するため、ばね力対抗して垂直の方向に移動できるようにすることを提案する。最後に移動することができる制限手段は、追加して作用手段が作用する滑り板によって上昇できるようにすることを提案する。これによって使用者は垂直方向に移動することができる制限手段によって開放された有効空気開口部を、恒久的に全部または中間部に開放し、例えば良好に粗い物体を取り去ることができる。使用者の調整によっても吸引室の負圧が高すぎる場合は、有効空気開口部を更に開放するため上述の手段（吸引室の変位することができる探索体または負圧に関連した制御）を適用すること。   This problem is solved essentially by the object of claim 1, wherein the restricting means can be moved vertically over a partial range, the restricting means being a negative pressure generated in the suction duct and / or the advancement of the suction nozzle. The emphasis is on being able to climb automatically in connection with backward movement. The configuration according to the invention creates the possibility of limiting the negative pressure in the suction chamber to a maximum value. This value is chosen high to further ensure the dust suction or cleaning effect, and on the other hand, it is chosen low so that the sliding force can withstand the user. The air additionally flowing in by the adjustment of the selected restricting means slides in close contact with the carpet, so that the dirt adhering to the carpet collar can be satisfactorily sucked at this position. Further, the restricting means which can be raised or lowered is formed in the form of a sliding plate which can move substantially vertically, and the width of such an effective air sliding plate or a rough dirt or cleaning air sliding plate is the floor nozzle. Preferably, both sides of the restricting means that can be selected and smaller than the overall width of the carpet floor to be operated are kept low by adjacent non-movable restricting means such as floor plates or sliding plates. In this connection, the width of the limiter or the sliding plate that can be moved is 50 to 200 mm. The amount of air flowing into the suction chamber can be adjusted by the restriction means, from the fully closed state where the sliding plate or the lower corner of the restriction means closes the floor to be cleaned, from the desired cleaning load or geometric It can be adjusted to the maximum desired opening amount restricted by the actual situation. The lower corner of the sliding plate or the restricting means which can move vertically is preferably formed by an airtight lip or a kind of sliding plate. The opening set by the rising limiting means here can be formed for accepting rough objects. For optimizing dust reception from the gap, the large opening is closed by a restricting means, which is formed from a segment of bristle band or an airtight lip. In this regard, it is preferable to further press the limiting means in the downward direction. Further, a wiper-like search body is arranged in the suction nozzle, and the wiper-like search body is displaced by a part of the base that intrudes into the suction chamber, particularly a part of the sucked carpet. Propose to control the rise of In particular, when a dense carpet is sucked, the negative pressure in the suction chamber increases as the carpet or a section of the carpet that makes the suction chamber almost airtight from the lower side is strongly sucked. enter in. As a result, the wiper-like search body is displaced by being hit, whereby the restricting means is raised to adjust the negative pressure in the suction chamber. The negative pressure in the suction chamber is thereby improved and adjusted to a small sliding force. In this regard, it is advantageous if the displacement response threshold of the search object can be adjusted. With this configuration, the negative pressure threshold value can be adjusted, and the limit means is raised only in order to adjust the negative pressure. The exploratory body is advantageously arranged in a suction chamber and is a wiper-like displaceable brush. The brush can in this case move outside the suction chamber and around a pivot axis which is adjusted parallel to the rotation axis of the brush, which is simultaneously driven by the brush rotation axis, for example a toothed belt. It may be a motor shaft. When a part of the carpet is sucked into the suction chamber during the suction operation, the brush is raised. In this case, the brush that simultaneously functions as the search body raises the limiting means for adjusting the negative pressure of the suction chamber when the reaction threshold value is exceeded. The negative pressure itself acting on the suction chamber is replaced by the ascending force of the limiting means. The negative pressure acting on the suction chamber can always be measured. The limiting means is opened when a predefined threshold is exceeded. Basically irrespective of the embodiment, the movement of the limiting means in the vertical direction is proportional to the measured negative pressure or proportional to the displacement path of the search body. Further, it is possible to cause the negative pressure to act on the negative pressure piston and to be firmly coupled to the action part of the action means acting on the limiting means. This realizes a mechanical solution in which the negative pressure generated in the suction chamber leads to the vertical position of the restricting means that can move. As an alternative or combination of the solutions described above, the suction nozzle may be provided with a wiper-like search body and tilted according to the forward manual and reverse movement of the suction nozzle. In general, a rough object is taken in by advancing the suction movement, while suction from a gap on the premise of a relatively high negative pressure is used in the forward and backward movements. The wiper-like search body provided in the suction nozzle according to the present invention raises the restricting means that can automatically open, that is, move vertically in order to take in a rough object, while moving forward, while moving backward, The shutter formed by the restricting means that can move in the vertical direction automatically is closed. The search body related to this is formed into a lever shape, and the lever section of the search body opposite the base, that is, the floor to be sucked, controls the movement of the limiting means. Alternatively, the distinction between forward and reverse movement can be made by ascertaining the direction of rotation of the rollers or other components that rotate together, as the case may be. The actuating means acting on the restricting means may be a lever connecting rod or a load transmitting steel cable, in which case the connection of the load transmitting steel cable based on the searching body insulator section is closer to the fixing of the restricting means than another position. Propose that. The lever-like search body, which can be tilted by changing the forward and backward movement of the floor nozzle that cooperates with the base, can move in the vertical direction against the spring force to adjust the excessive displacement of its rotating shaft Suggest to do so. It is proposed that the restricting means that can be moved last is additionally allowed to rise by the sliding plate on which the acting means acts. This allows the user to permanently open all or part of the effective air opening opened by the restricting means which can move in the vertical direction, for example to remove a rough object well. If the negative pressure in the suction chamber is too high due to the user's adjustment, apply the above-mentioned means (search body that can be displaced in the suction chamber or control related to negative pressure) to further open the effective air opening To do.

以下本発明を、実施例のみを描写した添付図面によって詳細に説明する。   The invention will now be described in detail with reference to the accompanying drawings, in which only examples are depicted.

絨毯床の吸引作業の操作性の優れた吸引ノズルが得られる。   A suction nozzle with excellent operability for suction work on the carpet floor can be obtained.

最初に図示し説明する図１の図示に関する、図示されていない掃除機の床ノズル１である。床ノズル１は附属器具として形成され、電気的および流体的に掃除機に接続することができる。   FIG. 1 is a floor nozzle 1 of a vacuum cleaner not shown with respect to the illustration of FIG. The floor nozzle 1 is formed as an accessory and can be electrically and fluidly connected to the cleaner.

床ノズル１は普通の方法で、床ノズル１の正面側の範囲に配置されほぼ幅全部にわたって形成され、普通の移動方向ｒの横方向に延びる吸引室２を備えている。吸引室２は清掃する床３に対して吸引口４が開口している。   The floor nozzle 1 is provided with a suction chamber 2 which is arranged in the range of the front side of the floor nozzle 1 and is formed over substantially the entire width and extends in the lateral direction of the normal movement direction r in the usual manner. The suction chamber 2 has a suction port 4 opened to the floor 3 to be cleaned.

吸引室２または吸引口４は、普通の移動方向ｒの前後に配置されそれぞれ吸引室２と平行に延びる制限手段５が設けられ、例えば剛毛の縁枠または気密な唇状体である。この制限手段５は吸引室２を長く延びた方向に区分する。吸引室２は両方の側面側でケーシング側の壁の区間で仕切られる。   The suction chamber 2 or the suction port 4 is provided with restricting means 5 disposed in front of and behind the normal movement direction r and extending in parallel with the suction chamber 2, for example, a bristle edge frame or an airtight lip. This restricting means 5 divides the suction chamber 2 in a direction extending long. The suction chamber 2 is partitioned on both side surfaces by a wall section on the casing side.

さらに吸引室２には回転駆動することができるブラシ６が清掃する床３のブラシ作業のため配置され、ブラシの軸は普通の進行方向ｒと横向きに調整される。さらにブラシ６は、剛毛７が普通の床作業で器具の底８から下側に突き出るように配置される。   Further, a brush 6 which can be driven to rotate is arranged in the suction chamber 2 for the brush work of the floor 3 to be cleaned, and the brush shaft is adjusted sideways with the normal traveling direction r. Furthermore, the brush 6 is arranged so that the bristles 7 protrude downward from the bottom 8 of the instrument in normal floor work.

床ノズル１の正面側に配置された制限手段５の部分的範囲５’は垂直方向に移動することができるように形成され、附属する床ノズル１の正面の壁９は、制限手段５の移動することができる部分的範囲５’の幅に適合させた窓１０が設けられる。普通の進行方向ｒの横方向に測定した移動することができる制限手段５’およびそれに対応する窓１０の幅は、図示した例では床ノズル全体幅のほぼ２／３に相当するので、移動することができる制限手段５’の両側に、固定すなわち垂直に動くことができない制限手段５が配置される。   A partial range 5 ′ of the limiting means 5 arranged on the front side of the floor nozzle 1 is formed so that it can move in the vertical direction, and the wall 9 in front of the floor nozzle 1 attached is the movement of the limiting means 5. A window 10 is provided that is adapted to the width of the partial range 5 'that can be done. The width of the restricting means 5 ′ that can be moved and measured in the transverse direction of the normal traveling direction r corresponds to approximately 2/3 of the entire width of the floor nozzle in the illustrated example. On both sides of the restricting means 5 'which can be arranged is a restricting means 5 which can not be fixed or moved vertically.

図２ないし４に示された第１および第２の実施例では、移動することができる制限手段５’は移動方向と横向きに調整された腕木１１によって操作され、床ノズル１のケースの別の側に固定された引っ張りばね１２が取り付けられる。ばねは移動することができる制限手段５’を下降方向、すなわち作業する床３に接触する位置に荷重を加える。   In the first and second embodiments shown in FIGS. 2 to 4, the restricting means 5 ′ which can be moved is operated by a brace 11 which is adjusted in the direction of movement and sideways, and is different from the case of the floor nozzle 1. A tension spring 12 fixed to the side is attached. The spring applies a load in the downward direction, i.e. the position in contact with the floor 3 on which the working means 3 'is restricted.

腕木１１の自由端の範囲には、図２および３による第１の実施例では制限手段５’の移動方向に調節された調節ねじ１３が噛み合い、これによって変位反応しきい値を調整することがきるかまたはブラシの磨耗を考慮することができる。   In the first embodiment according to FIGS. 2 and 3, the adjusting screw 13 adjusted in the moving direction of the restricting means 5 ′ is engaged in the range of the free end of the arm 11, so that the displacement reaction threshold can be adjusted. Or brush wear can be taken into account.

さらに図２および３による第１の実施例では、吸引室２に配置されたブラシ６をワイパに変位させることができる。そのためブラシ６はその軸の範囲をワイパーアーム１４に取り付け、アームは吸引室２の外側でブラシ軸と平行に延びる旋回軸ｘにより旋回移動することができる。この旋回軸ｘはブラシ６のモータ回転軸、例えばベルトにより駆動する電気モータ１５と一致させる。また図示したように電気モータ１５をワイパーアーム１４とともに軸ｘの周りを旋回させることも考えられる。   Furthermore, in the first embodiment according to FIGS. 2 and 3, the brush 6 arranged in the suction chamber 2 can be displaced to the wiper. Therefore, the brush 6 is attached to the wiper arm 14 in the range of its axis, and the arm can be swung around the swivel axis x extending parallel to the brush axis outside the suction chamber 2. The swivel axis x coincides with the motor rotation axis of the brush 6, for example, the electric motor 15 driven by a belt. It is also conceivable to rotate the electric motor 15 around the axis x together with the wiper arm 14 as shown.

さらにブラシ６がその剛毛７と共に、自重によって常に作業する床３と接触させる配置を選定する。ワイパ式配置によってブラシ６は例えば床の非平面度にも反応する。   Further, an arrangement is selected in which the brush 6 and the bristles 7 are brought into contact with the floor 3 that is always operated by its own weight. Due to the wiper arrangement, the brush 6 also reacts to, for example, the non-planarity of the floor.

そのためワイパーアーム１４を少し延ばし、回転移動しないようワイパーアーム１４に配置する探索体１６を形成する。   Therefore, the wiper arm 14 is slightly extended to form a search body 16 that is disposed on the wiper arm 14 so as not to rotate.

移動することができる制限手段５’は、吸引室に発生する負圧によって自動的に上昇することができる。密度の高い絨毯床３の吸引の場合、吸引室２に発生する負圧は、制限手段５の気密性によって吸引口にある絨毯一部区間１７は強く引き込まれ、ワイパ状変位したブラシ６およびワイパーアーム１４はそれによって上昇する。調整ねじ１３によって調整可能な反応しきい値を超えると、ワイパ状の探索体１６は調整ねじ１３に強く当たり、調整ねじおよび腕木１１により移動することができる制限手段５’の垂直方向への変位が生ずる（図３参照）。この変位は引っ張りばね１２の力に対抗して行なわれる。移動することができる制限手段５’の上昇によってケース側の窓１０は隙間が開き、隙間の高さは吸引室２に発生した負圧および、同時に生ずる絨毯一部区間１７の吸引高さに関連する。窓１０の開口により並列流が流れ込み、吸引室２に発生した負圧の低下に対して有利に働き滑動力が低下する。流入した空気は絨毯３からの塵埃または絨毯３上の汚れを取り除く。並列空気は利用されないで吸引されるのではなく、絨毯床の清掃に利用される。   The restricting means 5 'that can move can be automatically raised by the negative pressure generated in the suction chamber. In the case of suction of the carpet bed 3 having a high density, the negative pressure generated in the suction chamber 2 is strongly drawn in the carpet partial section 17 at the suction port due to the airtightness of the restricting means 5, and the wiper-displaced brush 6 and wiper The arm 14 is thereby raised. When the reaction threshold adjustable by the adjusting screw 13 is exceeded, the wiper-like search body 16 strongly hits the adjusting screw 13 and the vertical displacement of the limiting means 5 ′ that can be moved by the adjusting screw and the arm 11. (See FIG. 3). This displacement is performed against the force of the tension spring 12. As the restricting means 5 ′ that can be moved rises, the case-side window 10 opens a gap, and the height of the gap is related to the negative pressure generated in the suction chamber 2 and the suction height of the carpet partial section 17 that occurs simultaneously. To do. A parallel flow flows in through the opening of the window 10 and works advantageously against a decrease in the negative pressure generated in the suction chamber 2, thereby reducing the sliding force. The inflowing air removes dust from the carpet 3 or dirt on the carpet 3. The parallel air is not used and is not sucked, but is used to clean the carpet floor.

この自動的な負圧制御に加え、使用者は移動することができる制限手段５’によって、自由に与えることができる有効空気開口部を希望する寸法に恒久的に開放することができる。このため器具の上部に滑り金１８を設け、操作手段１９によって移動することができる制限手段５’の垂直方向変位に影響を与える。この操作手段１９は、図２および３に示す第１の実施例および図４に示す第２の実施例においても、梃子連結棒２０の片側の端部を滑り金１８に当てるようにし、他方の端部を移動することができる制限手段５’の上部自由端に取り付ける。滑り金１８の変位により、梃子連結棒２０を介して移動することができる制限手段５’は、引っ張りばね１２の力に対抗して吸引室２に発生する負圧と無関係に、またはブラシ６の高さの変位と無関係に希望する位置に変位する。これによって有効空気開口部を希望する寸法に恒久的に開放させ、例えばより良好な粗い物体の吸引性を得ることができる。   In addition to this automatic negative pressure control, the user can permanently open the freely available effective air opening to the desired dimensions by means of a restricting means 5 'that can be moved. For this reason, a sliding metal 18 is provided on the upper part of the instrument, which affects the vertical displacement of the restricting means 5 ′ that can be moved by the operating means 19. In the first embodiment shown in FIGS. 2 and 3 and the second embodiment shown in FIG. 4, the operating means 19 is arranged so that the end of one side of the lever connecting rod 20 is brought into contact with the sliding metal 18, The end is attached to the upper free end of the restricting means 5 'which can be moved. The restricting means 5 ′ which can be moved via the lever connecting rod 20 by the displacement of the sliding metal 18 is independent of the negative pressure generated in the suction chamber 2 against the force of the tension spring 12 or of the brush 6. Displaces to the desired position regardless of the height displacement. This allows the effective air openings to be permanently opened to the desired dimensions, for example to obtain better rough object suction.

第１の実施例の代替または組み合わせとして、図４により吸引室２に作用する負圧を直接制限手段５’の上昇力に転換することができる。このため吸引室側の負圧を負圧ピストン２１に作用させ、ピストンを反対側の作動側に上述の操作手段１９または梃子連結棒２０に作用する作動部品２２に連結する。この作動部品２２は関節状に支持され、同時に滑り金１８と共同作用する梃子連結棒２０の梃子アームに作用する梃子となる。   As an alternative or combination of the first embodiment, the negative pressure acting on the suction chamber 2 can be converted directly into the ascending force of the restricting means 5 'according to FIG. For this reason, the negative pressure on the suction chamber side is applied to the negative pressure piston 21, and the piston is connected to the operating part 22 acting on the above-described operating means 19 or the lever connecting rod 20 on the opposite operating side. This actuating part 22 is supported in an articulated manner and at the same time acts as a lever acting on the lever arm of the lever connecting rod 20 that cooperates with the sliding metal 18.

この実施態様の場合は自由になる有効空気開口部の大きさは、ブラシの上下位置すなわち絨毯の吸い込み寸法により制御するのではなく、吸引室２の負圧によって制御する。負圧ピストン２１を介して負圧の高さによって、梃子連結棒２０は移動することができる制限手段５’が引っ張りばね１２の力に対抗して上昇するように上下に変位する。このシステムの場合滑り金１８によって有効空気開口部を恒久的にある開口位置に保持することもできる。   In this embodiment, the size of the effective air opening that is free is controlled not by the vertical position of the brush, that is, by the suction size of the carpet, but by the negative pressure of the suction chamber 2. Depending on the height of the negative pressure via the negative pressure piston 21, the lever connecting rod 20 is displaced up and down so that the restricting means 5 ′ capable of moving rises against the force of the tension spring 12. In the case of this system, the effective air opening can also be permanently held in a certain opening position by means of the sliding metal 18.

図５ないし８に第３の実施態様を示し、この場合は移動することができる制限手段５’が、床ノズルの前進および後進の移動によって自動的に上昇される。ここでも両方の第１の実施例により、普通の吸引方向ｒの前方の制限手段５の移動することができる制限手段５’を、有効空気開口部２３を開放するため上昇させることができる。
この移動することができる制限手段５’は、下降した位置すなわち床との接触位置に圧縮ばね２４により押し付けられる。 A third embodiment is shown in FIGS. 5 to 8, in which the restricting means 5 ′, which can be moved, is automatically raised by forward and backward movement of the floor nozzle. Here again, according to both first embodiments, the restricting means 5 ′ to which the restricting means 5 in front of the normal suction direction r can move can be raised to open the effective air opening 23.
This movable restricting means 5 ′ is pressed by the compression spring 24 in the lowered position, that is, the position in contact with the floor.

移動することができる制限手段５’は、荷重伝達鋼索２５として形成される作用手段１９によってワイパ状の探索体２６に結合され、探索体は作業する床に接触し、床ノズル１の前進移動ｒおよび後進移動ｒ’に応じて交互に傾く。清掃する床と常に接触する探索体２６は気密要素の形状に形成されると好ましい。   The restricting means 5 ′ which can be moved is coupled to a wiper-like search body 26 by an actuating means 19 formed as a load transmission steel cable 25, the search body touching the floor to be worked on, and the forward movement r of the floor nozzle 1. And it inclines alternately according to reverse movement r '. The search body 26 which is always in contact with the floor to be cleaned is preferably formed in the shape of an airtight element.

図示した実施例では、探索体２６は床ノズル１の進行方向に対し横方向に調整された軸ｙの周りを旋回することができ、垂直方向に動き横方向費に案内される梃子区間２７が形成される。梃子区間は圧縮ばね２８によってケースの床８に向いた基本位置に押し付けられる。   In the illustrated embodiment, the search body 26 can swivel about an axis y that is adjusted transversely to the direction of travel of the floor nozzle 1 and has a lever section 27 that moves vertically and is guided by lateral costs. It is formed. The insulator section is pressed by the compression spring 28 to the basic position facing the floor 8 of the case.

梃子区間２７には荷重伝達鋼索２５の芯の端部が固定される。   The end of the core of the load transmission steel cable 25 is fixed to the insulator section 27.

探索体２６は選択された床ノズル１の移動方向によって、自動的に最低点位置を通り抜け、探索体２６の両側の振れの終端位置はストッパによって限定される。この場合探索体２６は矢印ｒ方向（図５参照）の進行移動の場合は、矢印ｒ’方向（図５参照）の後進移動の場合よりも大きな傾き位置とする。これによって梃子区間２７の垂直方向の位置は、両方の移動方向で異なる。図５による前進移動の場合は、最低位置に留まる梃子区間２７および荷重伝達鋼索２５によって移動することができる制限手段５’は、有効空気開口部２３を開放するため上昇する。戻り工程すなわち床ノズルの後進移動および同時に生ずる探索体２６の方向変換は、梃子区間２７を上昇させ荷重伝達鋼索２５を介して移動することができる制限手段５’の床との接触位置を低下させるように作用する。有効空気開口部２３はその後閉鎖される。   The search body 26 automatically passes through the lowest point position depending on the selected moving direction of the floor nozzle 1, and the end positions of the shakes on both sides of the search body 26 are limited by the stoppers. In this case, the search body 26 has a larger inclination position in the case of the forward movement in the direction of the arrow r (see FIG. 5) than in the case of the backward movement in the direction of the arrow r ′ (see FIG. 5). As a result, the vertical position of the lever section 27 differs in both movement directions. In the case of forward movement according to FIG. 5, the lever section 27 staying at the lowest position and the restricting means 5 ′ which can be moved by the load transmission steel line 25 are raised to open the effective air opening 23. The return process, that is, the backward movement of the floor nozzle and the direction change of the search body 26 occurring simultaneously, raises the insulator section 27 and lowers the contact position of the limiting means 5 ′ that can move through the load transmission steel cable 25 with the floor. Acts as follows. The effective air opening 23 is then closed.

この構成により、最も簡単な方法で床ノズル1の走行移動に関連した制限手段の上昇および下降が達成される。傾くことができる探索体２６の代替案として、前進および後進を区別するため、回転方向を場合によってはローラまたはその他の一緒に回転する床ノズル１の構成部品を利用することもできる。   With this configuration, the raising and lowering of the limiting means related to the traveling movement of the floor nozzle 1 is achieved in the simplest way. As an alternative to the search body 26, which can be tilted, it is also possible to utilize a roller or other components of the floor nozzle 1 that rotate together, possibly with rollers, in order to distinguish between forward and reverse.
