(e)押さえロールの上方に粘着ロールを配置し、清掃時に両ロールが接触して反対方向に一緒に回転するようにしたから、押さえロールの回転に粘着ロールを連れ回り回転させて駆動できる。粘着ロールの駆動ロールを格別に必要としない。塵取部等のゴミ回収スペースを大きくとることができる。 (e) Since the adhesive roll is disposed above the pressing roll and the both rolls come into contact with each other and rotate together in the opposite direction during cleaning, it can be driven by rotating the pressing roll along with the rotation of the pressing roll. There is no need for an adhesive roll drive roll. A large space for collecting dust such as a dust collector can be secured.

(f)押さえロールと掻き上げロールによって挟み込まれて弾き飛ばされるゴミを、掻き上げロールの後部の塵取部に回収できる。 (f) The dust sandwiched between the pressing roll and the scraping roll and blown off can be collected in the dust collecting section at the rear of the scraping roll.

清掃具１０は、床面１等の清掃面上のゴミ、例えば大粒、小粒の粒ゴミ、又はカーペット等の繊維に絡み付いた髪の毛等のゴミを捕集するものであり、図１〜図６に示す如く、柄１１の先端部に左右揺動軸１２を介して支持アーム１３を清掃方向に交差する左右方向に揺動自在に結合し、支持アーム１３の両側アーム部１３Ａに前後揺動軸１４を介してフレーム１５を清掃方向に沿う前後方向に揺動自在に支持している。 The cleaning tool 10 collects trash on the cleaning surface such as the floor surface 1 such as large and small particle trash or hair tangled around fibers such as carpets. As shown, a support arm 13 is coupled to the tip of the handle 11 via a left / right swing shaft 12 so as to be swingable in the left / right direction intersecting the cleaning direction, and the front / rear swing shaft 14 is connected to both arm portions 13A of the support arm 13. The frame 15 is supported so as to be swingable in the front-rear direction along the cleaning direction.

清掃具１０は、床面１と接触して転動する硬質の左右前輪２１と左右後輪２２（接地部）をフレーム１５の前後の両側部に回転自在に設ける。尚、前輪２１の回転軸２１Ａは、図３に示す如く、フレーム１５の清掃方向の前後に沿って設けた長孔１５Ａに支持され、前輪２１は前進時には長孔１５Ａの後方側に、後進時には長孔１５Ａの前方側に位置付けられる。清掃具１０は、床面１に摺接する硬質シューを接地部として設けるものでも良い。 The cleaning tool 10 is provided with hard left and right front wheels 21 and left and right rear wheels 22 (grounding portions) that roll in contact with the floor 1 so as to be rotatable on both front and rear sides of the frame 15. As shown in FIG. 3, the rotating shaft 21A of the front wheel 21 is supported by a long hole 15A provided along the front and rear in the cleaning direction of the frame 15, and the front wheel 21 is moved to the rear side of the long hole 15A when moving forward and when moving backward. It is positioned on the front side of the long hole 15A. The cleaning tool 10 may be provided with a hard shoe that is in sliding contact with the floor surface 1 as a grounding portion.

清掃具１０は、フレーム１５の清掃方向に沿う前後に弾性押さえロール３０（清掃ロール）と弾性掻き上げロール４０を平行に並べて配置し、それら両ロール３０、４０を前輪２１と後輪２２の接地線（前輪２１の接地点と後輪２２の接地点を結ぶ直線）よりも外方（床面１に入る側）へ張り出る大径にする。 In the cleaning tool 10, an elastic pressing roll 30 (cleaning roll) and an elastic scraping roll 40 are arranged in parallel on the front and rear along the cleaning direction of the frame 15, and both the rolls 30 and 40 are grounded to the front wheel 21 and the rear wheel 22. The diameter is larger than the line (the straight line connecting the grounding point of the front wheel 21 and the grounding point of the rear wheel 22) to the outside (the side entering the floor 1).

押さえロール３０は、フレーム１５のゴミ導入側に配置され、清掃方向に直交する横方向において、左右の前輪２１、後輪２２に挟まれる概ね全域に渡って床面１に接する範囲で、フレーム１５に支持される前輪２１の回転軸２１Ａに支持され、床面１に接触して転動する。押さえロール３０は、前輪２１の回転力により同軸駆動されるものであり、前輪２１の回転軸２１Ａに固定的に結合されても良いが、床面１と掻き上げロール４０に対して大きくこすれ回転することのないように、回転軸２１Ａに摩擦接触して駆動される。押さえロール３０は、床面１に接する少なくとも表面を弾性たわみできる材質（弾性可撓材料）にて構成する。押さえロール３０としては、筒状のスポンジロール、可撓プラスチックロール、ゴムロール等を採用できるが、スポンジロール等のクッションロールが好適である。 The pressing roll 30 is disposed on the dust introduction side of the frame 15, and is in a range in which the pressing roll 30 is in contact with the floor surface 1 over almost the entire region sandwiched between the left and right front wheels 21 and the rear wheel 22 in the lateral direction perpendicular to the cleaning direction. Is supported by the rotating shaft 21 A of the front wheel 21 that is supported on the floor 1, and rolls in contact with the floor surface 1. The pressing roll 30 is coaxially driven by the rotational force of the front wheel 21 and may be fixedly coupled to the rotating shaft 21A of the front wheel 21, but is rotated by rubbing with respect to the floor surface 1 and the scraping roll 40. In order to prevent this, the rotary shaft 21A is driven in frictional contact. The pressing roll 30 is made of a material (elastic flexible material) capable of elastically bending at least the surface in contact with the floor surface 1. As the pressing roll 30, a cylindrical sponge roll, a flexible plastic roll, a rubber roll, or the like can be adopted, but a cushion roll such as a sponge roll is preferable.

掻き上げロール４０は、フレーム１５の押さえロール３０に対するゴミ導入側と反対側に配置され、清掃方向に直交する横方向において、押さえロール３０に相並ぶ範囲で、フレーム１５の両側部に支持される左右伝動輪４１の回転軸４１Ａに支持され、床面１に接触して転動する。左右の各伝動輪４１は、左右の各前輪２１の後方に回転自在に支持され、前進時の前輪２１に接して該前輪２１に連れ回り駆動される（図２）。前輪２１に同軸駆動される押さえロール３０と、前輪２１に伝動輪４１を介して駆動される掻き上げロール４０とは、互いに反対回転するものになる。尚、後退時の前輪２１は、前述した如く、フレーム１５に設けた長孔１５Ａの前方側に移動し、伝動輪４１から離れるため、伝動輪４１を連れ回り駆動させることがない（図３）。掻き上げロール４０は、床面１に接する少なくとも表面を弾性たわみできる材質（弾性可撓材料）にて構成する。掻き上げロール４０としては、筒状のスポンジロール、エアクッションロール（ゴム風船状のロール）、可撓プラスチックロール、ゴムロール、ブラシロール等を採用できるが、押さえロール３０を構成するスポンジロールとの組合せにおいて、ブラシロールが好適である。 The scraping roll 40 is disposed on the side opposite to the dust introduction side of the pressing roll 30 of the frame 15 and is supported on both sides of the frame 15 in a range aligned with the pressing roll 30 in the lateral direction perpendicular to the cleaning direction. It is supported by the rotation shaft 41A of the left and right transmission wheels 41 and rolls in contact with the floor surface 1. The left and right transmission wheels 41 are rotatably supported behind the left and right front wheels 21, and are driven by the front wheels 21 in contact with the front wheels 21 during forward movement (FIG. 2). The pressing roll 30 driven coaxially to the front wheel 21 and the scraping roll 40 driven to the front wheel 21 via the transmission wheel 41 rotate opposite to each other. As described above, the front wheel 21 at the time of reverse movement moves to the front side of the long hole 15A provided in the frame 15 and moves away from the transmission wheel 41, so that the transmission wheel 41 is not driven and driven (FIG. 3). . The scraping roll 40 is made of a material (elastic flexible material) capable of elastically bending at least the surface in contact with the floor surface 1. As the scraping roll 40, a cylindrical sponge roll, an air cushion roll (rubber balloon roll), a flexible plastic roll, a rubber roll, a brush roll, etc. can be adopted, but in combination with the sponge roll constituting the presser roll 30 In this case, a brush roll is suitable.

清掃具１０は、押さえロール３０の半径と掻き上げロール４０の半径の和を、フレーム１５に支持されたそれら両ロール３０、４０の軸間距離より大きくし、結果としてそれら両ロール３０、４０をそれらの接触部の弾性たわみ変形によって互いに食い込ませ接触させる接触部を形成し、該接触部の下端から床までの高さを押さえロール３０が取り込もうとするゴミの大きさより小さくする（図１）。 The cleaning tool 10 makes the sum of the radius of the press roll 30 and the radius of the scraping roll 40 larger than the distance between the axes of both the rolls 30 and 40 supported by the frame 15, and as a result, the both rolls 30 and 40 are Contact portions are formed which are brought into contact with each other by elastic deflection deformation of the contact portions, and the height from the lower end of the contact portion to the floor is made smaller than the size of dust to be taken in by the pressing roll 30 (FIG. 1).

清掃具１０は、床面１に前輪２１と後輪２２を接触させて転動させる清掃時に、図１に示す如く、床面１に接する押さえロール３０と掻き上げロール４０を床面１との接触部で前輪２１と後輪２２の接地線よりも張り出た大外径部分を大きく弾性たわみ変形させるとともに、それら両ロール３０、４０を互いに概ね同一周速で反対回転させる。両ロール３０、４０は互いに食い込み、かつ床面１に対して大きく弾性たわみ変形して食い込み、また押さえロール３０に対して掻き上げロール４０の径を小さくし、両ロール３０、４０の会合点Ａと床面１との間に側面視三角形状のデッドスペース（隙間）を概ねなくし、両ロール３０、４０は床面１上で概ね隙間なく会合する。 As shown in FIG. 1, when the cleaning tool 10 performs cleaning by bringing the front wheel 21 and the rear wheel 22 into contact with the floor surface 1 and rolling it, the pressing roll 30 and the scraping roll 40 that are in contact with the floor surface 1 are placed on the floor surface 1. At the contact portion, the large outer diameter portion protruding from the ground line of the front wheel 21 and the rear wheel 22 is greatly elastically deformed, and both the rolls 30 and 40 are rotated in opposite directions at substantially the same peripheral speed. Both rolls 30 and 40 bite into each other and are greatly elastically deformed and bitten with respect to the floor surface 1, and the diameter of the scraping roll 40 is reduced with respect to the press roll 30, and the meeting point A of the two rolls 30 and 40. The dead space (gap) having a triangular shape in side view is substantially eliminated between the roll surface 1 and the floor surface 1, and both rolls 30 and 40 meet on the floor surface 1 with almost no gap.

従って、清掃具１０による清掃時に、押さえロール３０は床面１に対して大きくこすれずに回転しつつ床面１上のゴミを逃げないように押さえ込む。押さえロール３０を変形させて後方に導かれた床面1上のゴミを、押さえロール３０と掻き上げロール４０の間に挟みとり、両ロール３０、４０の回転によって床面1より上方に導いて、挟み力が解除されるとともに掻き上げロール４０がはじき飛ばして捕集する。即ち、押さえロール３０が押さえた床面1上のゴミは該押さえロール３０と掻き上げロール４０の会合点Ａでそれら両ロール３０、４０の間に挟み取られて床面１からつまみ上げられ、それら両ロール３０、４０の離隔点Ｂで押さえロール３０の弾性復元力により押し出されるとともに、掻き上げロール４０の弾性復元力により弾き飛ばされる。このゴミは、後述する塵取部５０に捕集される。 Accordingly, when cleaning is performed by the cleaning tool 10, the pressing roll 30 presses the dust on the floor surface 1 so as not to escape while rotating without rubbing significantly against the floor surface 1. Debris on the floor surface 1 guided rearward by deforming the pressing roll 30 is sandwiched between the pressing roll 30 and the scraping roll 40 and guided upward from the floor surface 1 by the rotation of both rolls 30 and 40. When the pinching force is released, the scraping roll 40 is flipped off and collected. That is, the dust on the floor surface 1 pressed by the pressing roll 30 is sandwiched between the rolls 30 and 40 at the meeting point A between the pressing roll 30 and the scraping roll 40 and picked up from the floor surface 1. While being pushed out by the elastic restoring force of the pressing roll 30 at the separation point B of both the rolls 30, 40, it is blown off by the elastic restoring force of the scraping roll 40. This dust is collected in a dust collector 50 described later.

清掃具１０は、具体例として示せば、図２に示す如く、押さえロール３０の直径を40mm（前輪２１の直径を34mm）、掻き上げロール４０の直径を25mm、押さえロール３０と掻き上げロール４０の軸間距離Ｌを25mm、伝動輪４１の直径を16mm、両ロール３０、４０を床面１に食い込ませたときの両ロール３０、４０の中心軸と床面１との距離Ｈを8〜10mmとする。 As shown in FIG. 2, the cleaning tool 10 has a diameter of the pressing roll 30 of 40 mm (the diameter of the front wheel 21 is 34 mm), a diameter of the scraping roll 40 is 25 mm, and the pressing roll 30 and the scraping roll 40 as shown in FIG. The distance L between the shafts is 25 mm, the diameter of the transmission wheel 41 is 16 mm, and the distance H between the center axis of both the rolls 30 and 40 and the floor 1 when the both rolls 30 and 40 are bited into the floor 1 is 8 to 10mm.

清掃具１０は、押さえロール３０としてクッションロールを用いるとき、押さえロール３０の表面のクッション部の厚みを好適には5mm以上にし、押さえロール３０の軸芯を除く全体をクッション部とするものでも良い。 When the cushion 10 is used as the pressing roll 30, the cleaning tool 10 may be such that the thickness of the cushion portion on the surface of the pressing roll 30 is preferably 5 mm or more, and the entire portion excluding the shaft core of the pressing roll 30 is used as the cushion portion. .

粘着ロールホルダ６０にあっては、固定側ロール支軸６３が回転カバー６２の一方の側壁を貫通し、窓枠６１の一方の側壁に挿通した固定ピン６５を固定側ロール支軸６３に螺着し、固定側ロール支軸６３を固定する。回転カバー６２は窓枠６１と固定側ロール支軸６３の間で隙間を有し、固定側ロール支軸６３に対して軽く回転できる。また、スライド側ロール支軸６４は窓枠６１の他方の側壁、回転カバー６２の他方の側壁を貫通し、その貫通端にスペーサ６６、コイルばね６７、スライドプレート６８を挿入後、固定ピン６９をスライド側ロール支軸６４に螺着し、スライド側ロール支軸６４を固定する。 In the adhesive roll holder 60, the fixed-side roll support shaft 63 passes through one side wall of the rotation cover 62, and the fixing pin 65 inserted through the one side wall of the window frame 61 is screwed to the fixed-side roll support shaft 63. Then, the fixed roll support shaft 63 is fixed. The rotation cover 62 has a gap between the window frame 61 and the fixed-side roll support shaft 63 and can rotate lightly with respect to the fixed-side roll support shaft 63. The slide-side roll support shaft 64 passes through the other side wall of the window frame 61 and the other side wall of the rotary cover 62. After inserting the spacer 66, the coil spring 67, and the slide plate 68 into the through end, the fixing pin 69 is inserted. The slide side roll support shaft 64 is screwed to fix the slide side roll support shaft 64.

粘着ロールホルダ６０は、押さえロール３０と粘着ロール７０をフレーム１５に支持された状態を維持して両ロール３０、７０の接触状態と非接触状態を切り替える隔離手段を構成する。具体的には、粘着ロールホルダ６０は、回転カバー６２の回転支軸としてのピン６５と支軸６４を、ロール支軸６３、６４と同芯にし、回転カバー６２をそれらの回転支軸まわりで開閉回転できる。 The adhesive roll holder 60 constitutes an isolating unit that maintains the state in which the pressing roll 30 and the adhesive roll 70 are supported by the frame 15 and switches between the contact state and the non-contact state of both the rolls 30 and 70. Specifically, the adhesive roll holder 60 has a pin 65 and a support shaft 64 as rotation support shafts of the rotation cover 62 that are concentric with the roll support shafts 63 and 64, and the rotation cover 62 is rotated around those rotation support shafts. Open and close can be rotated.

回転カバー６２は、図１０、図１２に示す如く、回転カバー６２の半円弧状断面又はＵ字状断面等の半割断面の前縁フランジ６２Ａを窓枠６１の前部上縁に当接する閉じ位置に位置付けられた状態で、窓枠６１を閉じ、両ロール支軸６３、６４に支持されている粘着ロール７０を覆い、両ロール３０、７０を接触状態にする。他方、図１１、図１３に示す如く、回転カバー６２の前縁フランジ６２Ａを窓枠６１の後部上縁に当接する開き位置に位置付けられた状態で、窓枠６１を開き、回転カバー６２を押さえロール３０と粘着ロール７０の間に介在して粘着ロール７０を外界に臨ませ、両ロール３０、７０を非接触状態にし、両ロール支軸６３、６４に新旧粘着ロール７０のコア７２を着脱し、又は両ロール支軸６３、６４にセットされている粘着ロール７０の使用済粘着シート７１を剥離除去可能にする。即ち、回転カバー６２は閉じ位置から開き位置へ移行するとき、回転カバー６２の前縁フランジ６２Ａと反対側の後縁部を押さえロール３０の上部外周にめり込ませ、これによって弾性たわみ変形せしめられた押さえロール３０の上部外周と粘着ロール７０の間に介在する。即ち、回転カバー６２は、押さえロール３０を変形させることによって両ロール３０、７０の表面の間を離間し、接触状態と非接触状態に切り替える。これにより、回転カバー６２を開き状態にして、両ロール支軸６３、６４にセットされている粘着ロール７０の粘着シート７１の使用済の１周巻き分を剥離除去しようとするとき、粘着シート７１を押さえロール３０の外周に粘着させずにスムースに剥離できる。粘着シート７１が１回使用分ずつ重ねて巻かれている場合には１回使用分を剥離するが、連続する粘着シート７１が巻かれていものは、１回使用分を剥離して切断除去する場合には粘着シート７１の剥離端を回転カバー６２の前縁又は後縁のエッジを用いて切断できる。 As shown in FIGS. 10 and 12, the rotary cover 62 is closed so that the front edge flange 62 A having a half-arc cross section or a U-shaped cross section of the rotary cover 62 abuts on the front upper edge of the window frame 61. In the state positioned, the window frame 61 is closed, the adhesive roll 70 supported by the two roll support shafts 63 and 64 is covered, and the two rolls 30 and 70 are brought into contact. On the other hand, as shown in FIGS. 11 and 13, the window frame 61 is opened and the rotation cover 62 is pressed while the front edge flange 62 A of the rotation cover 62 is positioned at the open position where it abuts against the upper rear edge of the window frame 61. It is interposed between the roll 30 and the adhesive roll 70 so that the adhesive roll 70 is exposed to the outside world, both the rolls 30 and 70 are brought into a non-contact state, and the core 72 of the old and new adhesive roll 70 is attached to and detached from both roll support shafts 63 and 64. Alternatively, the used pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 set on both roll support shafts 63 and 64 can be peeled and removed. That is, when the rotary cover 62 moves from the closed position to the open position, the rear edge portion opposite to the front edge flange 62A of the rotary cover 62 is sunk into the outer periphery of the upper portion of the pressing roll 30, thereby causing elastic deflection deformation. It is interposed between the upper outer periphery of the pressed presser roll 30 and the adhesive roll 70. In other words, the rotating cover 62 separates the surfaces of the rolls 30 and 70 by deforming the pressing roll 30 and switches between the contact state and the non-contact state. As a result, when the rotation cover 62 is opened and the used one turn of the pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 set on both roll spindles 63 and 64 is to be peeled and removed, the pressure-sensitive adhesive sheet 71 Can be smoothly peeled without sticking to the outer periphery of the pressing roll 30. When the pressure-sensitive adhesive sheet 71 is rolled up once for each use, the one-time use is peeled off, but when the pressure-sensitive adhesive sheet 71 is wound, the one-time use is peeled off and cut and removed. In some cases, the peeled end of the adhesive sheet 71 can be cut using the front edge or the rear edge of the rotary cover 62.

粘着ロールホルダ６０は、粘着ロール７０を両ロール支軸６３、６４にセットした状態で、図１４に示す如く、スライドプレート６８をコイルばね６７により固定ピン６９のフランジ側に押付け、スライドプレート６８とこれに相対する窓枠６１の一方の側壁との間隔を小さくし、粘着ロール７０が固定ピン６９から外れる軸方向ずれを防止する。他方、粘着ロール７０を両ロール支軸６３、６４から外すときには、図１５に示す如く、粘着ロール７０をスライドプレート６８の側に押す（Ｐ1）ことで、コイルばね６７を圧縮し、スライドプレート６８を窓枠６１の他方の側壁の側にスライドさせ、スライドプレート６８とこれに相対する窓枠６１の一方の側壁との間隔を大きくし、固定側ロール支軸６３側の粘着ロール７０の一端を持ち上げる（Ｐ2）ことで、粘着ロール７０を外す（粘着ロール７０を両ロール支軸６３、６４に取付ける場合も同じ）。 As shown in FIG. 14, the adhesive roll holder 60 presses the slide plate 68 against the flange side of the fixed pin 69 with the coil spring 67 in a state where the adhesive roll 70 is set on both roll support shafts 63 and 64. The distance from the one side wall of the window frame 61 opposite to this is reduced, and the axial displacement in which the adhesive roll 70 is detached from the fixing pin 69 is prevented. On the other hand, when the adhesive roll 70 is removed from both roll spindles 63 and 64, the coil spring 67 is compressed by pushing the adhesive roll 70 toward the slide plate 68 (P1) as shown in FIG. Is slid to the other side wall side of the window frame 61, the distance between the slide plate 68 and one side wall of the window frame 61 opposite to the slide plate 68 is increased, and one end of the adhesive roll 70 on the fixed side roll support shaft 63 side is By lifting (P2), the adhesive roll 70 is removed (the same applies to the case where the adhesive roll 70 is attached to both roll support shafts 63 and 64).

清掃具１０による清掃動作は以下の如くなされる。
(1)清掃具１０が柄１１に加える押付け操作力により前輪２１と後輪２２を床面１に押付けて前進せしめられると、前輪２１がフレーム１５の長孔１５Ａの後方側に移動して伝動輪４１にしっかり接し、前輪２１の回転力によって直に押さえロール３０を回転させるとともに、前輪２１の回転力を伝動輪４１経由で掻き上げロール４０に伝え、掻き上げロール４０を押さえロール３０と反対方向に回転させる。 The cleaning operation by the cleaning tool 10 is performed as follows.
(1) When the front wheel 21 and the rear wheel 22 are pressed against the floor surface 1 by the pressing operation force applied to the handle 11 by the cleaning tool 10 and moved forward, the front wheel 21 moves to the rear side of the long hole 15A of the frame 15 and is transmitted. While firmly contacting the wheel 41, the pressing roll 30 is directly rotated by the rotational force of the front wheel 21, and the rotational force of the front wheel 21 is transmitted to the scraping roll 40 via the transmission wheel 41, and the scraping roll 40 is opposite to the pressing roll 30. Rotate in the direction.

このとき、両ロール３０、４０は互いに食い込み、かつ床面１に接地する両ロール３０、４０の外径部分を大きく弾性たわみ変形させ、特に前輪２１の回転軸２１Ａと一緒に後方に移動するスポンジ製押さえロール３０が床面１との接触により後方に引きずられて掻き上げロール４０との隙間を殆どなくす。 At this time, the two rolls 30, 40 bite each other, and the outer diameter portions of both rolls 30, 40 contacting the floor 1 are greatly elastically deformed, and in particular, sponge that moves backward together with the rotating shaft 21 A of the front wheel 21. The presser roll 30 is dragged rearward by contact with the floor surface 1 so that there is almost no gap with the scraping roll 40.

これにより、両ロール３０、４０の会合点Ａと床面１との間に側面視三角形状のデッドスペースを概ねなくし、両ロール３０、４０は床面１上で概ね隙間なく会合する。 Thereby, the dead space having a triangular shape in a side view is substantially eliminated between the meeting point A of both the rolls 30 and 40 and the floor surface 1, and the both rolls 30 and 40 meet on the floor surface 1 with almost no gap.

(2)上述(1)により、押さえロール３０は床面１に対して大きくこすれずに回転しつつ床面１上のゴミを逃げないように押さえ込む。押さえロール３０が押さえた床面１上のゴミは該押さえロール３０と掻き上げロール４０の会合点Ａでそれら両ロール３０、４０の間に挟み取られて床面１からつかみ上げられ、押さえロール３０がゴミの形に倣う表面のクッション性弾性変形によってゴミを食い込ませ、このゴミをそれら両ロール３０、４０の離隔点Ｂで押さえロール３０の弾性復元力により押し出すとともに、掻き上げロール４０の弾性復元力により弾き飛ばされ、ゴミ送り込み口５４経由で塵取部５０のゴミ受け部５１に捕集される。 (2) According to the above (1), the pressing roll 30 presses the dust on the floor surface 1 so as not to escape while rotating without rubbing greatly against the floor surface 1. The dust on the floor surface 1 pressed by the pressing roll 30 is sandwiched between the rolls 30 and 40 at the meeting point A between the pressing roll 30 and the scraping roll 40, and is picked up from the floor surface 1 and pressed by the pressing roll. 30 is caused by the cushioning elastic deformation of the surface following the shape of the dust, and the dust is pushed out by the elastic restoring force of the pressing roll 30 at the separation point B of both the rolls 30 and 40, and the elasticity of the scraping roll 40 It is blown off by the restoring force and collected by the dust receiving part 51 of the dust collecting part 50 via the dust feeding port 54.

押さえロール３０の弾性的に復元された表面に付着するゴミは、押さえロール３０の外周に近接している上ゴミ止め部５３の下縁スクレーパにより掻き落とされてゴミ受け部５１に捕集される。 The dust adhering to the elastically restored surface of the presser roll 30 is scraped off by the lower edge scraper near the outer periphery of the presser roll 30 and collected in the dust receiving part 51. .

同時に、押さえロール３０の表面に巻き付いた髪の毛等のゴミが、押さえロール３０の上の粘着ロール７０の粘着シート７１に粘着捕捉される。
これにより、小さな紙片やスパゲッティ等の細長いゴミも捕集される。 At the same time, dust such as hair wound around the surface of the pressing roll 30 is caught and caught by the pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 on the pressing roll 30.
As a result, small trash such as small paper pieces and spaghetti is also collected.

(3)清掃具１０が後退せしめられるときには、床面１からの押付け操作力が解放されて押さえロール３０と掻き上げロール４０が床面１に対する反発力が前輪２１を床面１から浮かし、また前輪２１がフレーム１５の長孔１５Ａの前方側へ移動して伝動輪４１から離れ、押さえロール３０と掻き上げロール４０が逆回転しない。従って、塵取部５０のゴミ受け部５１に取り込んだゴミを、押さえロール３０と掻き上げロール４０の逆転によりゴミ受け部５１から吐き出すことがない。 (3) When the cleaning tool 10 is moved backward, the pressing operation force from the floor surface 1 is released, and the pressing roll 30 and the scraping roll 40 cause the repulsive force against the floor surface 1 to lift the front wheel 21 from the floor surface 1; The front wheel 21 moves to the front side of the long hole 15A of the frame 15 and moves away from the transmission wheel 41, so that the pressing roll 30 and the scraping roll 40 do not rotate in reverse. Accordingly, the dust taken into the dust receiving portion 51 of the dust collecting portion 50 is not discharged from the dust receiving portion 51 due to the reverse rotation of the pressing roll 30 and the scraping roll 40.

(4)塵取部５０のゴミ受け部５１に多量のゴミがたまったことを視認したら、後蓋５５を開いてゴミ受け部５１の後部開口５１Ａからゴミを除去する。 (4) When it is visually confirmed that a large amount of dust has accumulated in the dust receiver 51 of the dust collector 50, the rear cover 55 is opened to remove dust from the rear opening 51A of the dust receiver 51.

(5)粘着ロール７０の粘着シート７１に多量のゴミが捕捉されたことを視認したら、粘着ロールホルダ６０の回転カバー６２を開き、１周巻き分の粘着シート７１を剥離切断除去し、新規粘着面を露出せしめる。 (5) When it is visually confirmed that a large amount of dust has been captured on the pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70, the rotation cover 62 of the pressure-sensitive roll holder 60 is opened, and the pressure-sensitive adhesive sheet 71 for one turn is peeled off and removed. Expose the surface.

本実施例によれば以下の作用効果を奏する。
(a)押さえロール３０としてクッションロールを用いており、押さえロール３０のクッション部の厚みを最大径とする大きなゴミも小さなゴミもクッション部の変形によって包み込み、掻き上げロール４０の側に導き、押さえロール３０と掻き上げロール４０によって挟み込むから、清掃面にある大小様々のゴミをもらさず捕集することができる。 According to the present embodiment, the following operational effects can be obtained.
(a) A cushion roll is used as the presser roll 30, and large and small trash having the maximum diameter of the cushion part of the presser roll 30 is wrapped by deformation of the cushion part, guided to the side of the scraping roll 40, and pressed. Since it is sandwiched between the roll 30 and the scraping roll 40, it is possible to collect various kinds of garbage on the cleaning surface without getting them.

(b)押さえロール３０と掻き上げロール４０が互いに食い込んで接触する接触部を形成し、接触部の下端から床までの高さが取り込もうとするゴミの大きさより小さい。従って、取り込もうとするゴミが、押さえロール３０と掻き上げロール４０の接触部に挟み込まれ、床面１上の一定以上の大きさのゴミを捕集することができる。 (b) The pressing roll 30 and the scraping roll 40 form a contact portion that bites into contact with each other, and the height from the lower end of the contact portion to the floor is smaller than the size of the dust to be taken in. Accordingly, the dust to be taken in is sandwiched between the contact portions of the press roll 30 and the scraping roll 40, and the dust of a certain size or more on the floor surface 1 can be collected.

(c)押さえロール３０に対して掻き上げロール４０の径を小さくすることにより、掻き上げロール４０と押さえロール３０と床面１の間の隙間を小さくし、床面１上のゴミを押さえロール３０と掻き上げロール４０によって挟み込み易くする。 (c) By reducing the diameter of the scraping roll 40 with respect to the pressing roll 30, the gap between the scraping roll 40, the pressing roll 30, and the floor surface 1 is reduced, and the dust on the floor surface 1 is pressed. 30 and the scraping roll 40 make it easy to sandwich.

(d)掻き上げロール４０及び／又はクッションロールが弾性たわみ変形によって床面１に食い込むようにしたから、床面１上のゴミを押さえロール３０と掻き上げロール４０によって挟み込み易くする。 (d) Since the scraping roll 40 and / or the cushion roll bite into the floor surface 1 by elastic deflection, the dust on the floor surface 1 is easily sandwiched between the pressing roll 30 and the scraping roll 40.

(e)押さえロール３０の上方に粘着ロール７０を配置し、清掃時に両ロール３０、７０が接触して一緒に回転するようにしたから、押さえロール３０の回転に粘着ロール７０を連れ回り回転させて駆動できる。粘着ロール７０の駆動ロールを格別に必要としない。塵取部５０等のゴミ回収スペースを大きくとることができる。 (e) Since the adhesive roll 70 is disposed above the pressing roll 30 and both the rolls 30 and 70 are in contact with each other and rotate together during cleaning, the adhesive roll 70 is rotated along with the rotation of the pressing roll 30. Can be driven. The drive roll of the adhesive roll 70 is not particularly required. A large space for collecting dust such as the dust collector 50 can be provided.

(f)押さえロール３０と掻き上げロール４０によって挟み込まれて弾き飛ばされるゴミを、掻き上げロール４０の後部の塵取部５０に回収できる。 (f) The dust sandwiched between the pressing roll 30 and the scraping roll 40 and bounced off can be collected in the dust collector 50 at the rear of the scraping roll 40.

尚、本実施例によれば以下の作用効果も奏する。
(a)押さえロール３０と粘着ロール７０をフレーム１５に支持された状態を維持して両ロール３０、７０の接触状態と非接触状態を切り替える粘着ロールホルダ６０（隔離手段）を備える。従って、粘着ロール７０を交換するに際しては、粘着ロールホルダ６０（隔離手段）により粘着ロール７０を押さえロール３０から非接触にし、その後、該粘着ロール７０をロール支軸６３、６４から容易に取外しできる。 In addition, according to a present Example, there exist the following effects.
(a) An adhesive roll holder 60 (separating means) that switches between a contact state and a non-contact state of both rolls 30 and 70 while maintaining the state where the pressing roll 30 and the adhesive roll 70 are supported by the frame 15 is provided. Therefore, when exchanging the adhesive roll 70, the adhesive roll 70 can be removed from the press roll 30 by the adhesive roll holder 60 (isolation means), and then the adhesive roll 70 can be easily removed from the roll spindles 63 and 64. .

(b)清掃具１０に粘着ロール７０を支持したまま、粘着ロール７０の使用済粘着シート７１を剥離除去するに際しては、粘着ロールホルダ６０（隔離手段）により粘着ロール７０を押さえロール３０から非接触にし、その後、粘着ロール７０のシート端を引張れば、粘着ロール７０はロール支軸６３、６４に対して回転し、１周巻き分の使用済粘着シート７１を剥離除去できる。このとき、粘着ロール７０は、押さえロール３０から隔離されており、スムースに回転できるから、使用済粘着シート７１の剥離除去性は良い。 (b) When the used pressure-sensitive adhesive sheet 71 of the pressure-sensitive adhesive roll 70 is peeled and removed while the pressure-sensitive adhesive roll 70 is supported on the cleaning tool 10, the pressure-sensitive adhesive roll 70 is not contacted from the pressing roll 30 by the pressure-sensitive roll holder 60 (separating means). Then, if the sheet end of the adhesive roll 70 is pulled, the adhesive roll 70 rotates with respect to the roll support shafts 63 and 64, and the used adhesive sheet 71 for one turn can be peeled and removed. At this time, since the adhesive roll 70 is isolated from the pressing roll 30 and can be smoothly rotated, the peelable removal property of the used adhesive sheet 71 is good.

(c)粘着ロールホルダ６０（隔離手段）は、押さえロール３０を変形させて押さえロール３０の表面と粘着ロール７０の表面を離間させるから、接触状態から非接触状態に容易に切り替えできる。 (c) Since the adhesive roll holder 60 (separating means) deforms the pressing roll 30 to separate the surface of the pressing roll 30 and the surface of the adhesive roll 70, it can be easily switched from the contact state to the non-contact state.

(d)押さえロール３０と掻き上げロール４０が互いに食い込み、かつ床面１に対して大きくたわみ変形するから、両ロール３０、４０の会合点Ａと床面１との間に側面視三角形状のデッドスペースを概ねなくし、両ロール３０、４０を床面１上で概ね隙間なく会合させ得るものとなる。このため、押さえロール３０が押さえた床面１上のゴミの概ねを掻き上げロール４０との会合点Ａに移送し、その会合点Ａで両ロール３０、４０の間に挟み取り、それら両ロール３０、４０の離隔点Ｂで押さえロール３０が押し出すゴミを掻き上げロール４０にて弾き飛ばして捕集できる。 (d) Since the presser roll 30 and the scraping roll 40 bite each other and are greatly bent and deformed with respect to the floor surface 1, a triangular shape is formed between the meeting point A of the both rolls 30 and 40 and the floor surface 1. The dead space is substantially eliminated, and both rolls 30 and 40 can be associated with each other on the floor surface 1 with almost no gap. For this reason, most of the dust on the floor surface 1 pressed by the pressing roll 30 is transferred to the meeting point A with the scraping roll 40, and is sandwiched between the rolls 30 and 40 at the meeting point A. The dust pushed out by the pressing roll 30 at the separation points B of 30 and 40 can be collected by being scraped off by the scraping roll 40.

(e)押さえロール３０の下をすり抜ける薄い紙シート等のゴミは、反対回転中の掻き上げロール４０により押し戻されると、この押し戻された部分を両ロール３０、４０の会合点Ａで直ちに両ロール３０、４０の間に摘みとり、それら両ロール３０、４０の離隔点Ｂで押さえロール３０に押し出され、掻き上げロール４０にて弾き飛ばされて捕集される。 (e) When dust such as a thin paper sheet that passes under the pressing roll 30 is pushed back by the scraping roll 40 that is rotating in the opposite direction, the pushed-back portion is immediately pressed at the meeting point A of the both rolls 30 and 40. It picks between 30 and 40, is pushed out to the press roll 30 by the separation point B of these both rolls 30 and 40, is flipped off by the scraping roll 40, and is collected.

(f)筒状スポンジからなる押さえロール３０が、床面１の凹凸の全面に隙間なく倣うようにやわらかく変形して該凹凸をなす床面１内のゴミを押さえ、又は床面１上の大きなゴミに対してはやわらかくへこんでこれを包むようにして該大きなゴミを押さえ、それらのゴミを掻き上げロール４０との会合点Ａの側に確実に移送できる。 (f) The pressing roll 30 made of a cylindrical sponge softly deforms so as to follow the entire uneven surface of the floor surface 1 without gaps, and suppresses dust in the floor surface 1 that forms the uneven surface, or a large surface on the floor surface 1 The dust is softly dented and wrapped so as to hold the large dust, and the dust can be reliably transferred to the side of the meeting point A with the scraping roll 40.

(g)筒状スポンジからなる押さえロール３０は、髪の毛等のゴミが表面にからみつき、これに接する粘着ロール７０に粘着させて回収できる。押さえロール３０がブラシからなるときには、髪の毛等がブラシの芯にからみついて除去困難になる。 (g) The pressing roll 30 made of a cylindrical sponge can be collected by causing dust such as hair to be entangled with the surface and sticking to an adhesive roll 70 in contact with the surface. When the presser roll 30 is made of a brush, hair or the like is entangled with the core of the brush, making it difficult to remove.

(h)筒状スポンジからなる押さえロール３０は、粘着ロール７０を支えてこれを確実に連れ回りさせることができる。押さえロール３０がブラシからなるときには、粘着ロール７０の重量によりブラシが座屈し、粘着ロール７０を連れ回りさせることができない。 (h) The pressing roll 30 made of a cylindrical sponge can support the adhesive roll 70 and reliably rotate it. When the pressing roll 30 is made of a brush, the brush buckles due to the weight of the adhesive roll 70, and the adhesive roll 70 cannot be rotated.

尚、清掃具１０にあっては、塵取部５０のゴミ受け部５１が掻き上げロール４０の外周に沿って高く立ち上がる下ゴミ止め部５２と、押さえロール３０の外周に近接して粘着ロール７０の側を完全に遮断する上ゴミ止め部５３を備え、ゴミ送り込み口５４から後蓋５５の側に渡るゴミ受け空間の全域を閉塞状にするから、押さえロール３０及び掻き上げロール４０が弾き飛ばすゴミの捕集性が良い。 In the cleaning tool 10, the dust receiving part 51 of the dust collecting part 50 rises high along the outer periphery of the scraping roll 40 and the adhesive roll 70 close to the outer periphery of the pressing roll 30. The upper dust stopper 53 that completely shuts off the dust side is provided, and the entire dust receiving space extending from the dust inlet 54 to the rear lid 55 is closed, so that the pressing roll 30 and the scraping roll 40 flip off. Good collection of garbage.

また、清掃具１０にあっては、前輪２１の回転軸２１Ａに押さえロール３０を直に結合するものに限らず、前輪２１と押さえロール３０の間に増速ギアを介するものでも良い。また、押さえロール３０は前輪２１の回転力を駆動源とするものに限らず、他の駆動源により回転せしめられるものでも良い。 Further, the cleaning tool 10 is not limited to the one in which the pressing roll 30 is directly coupled to the rotating shaft 21 A of the front wheel 21, and may be one in which a speed increasing gear is interposed between the front wheel 21 and the pressing roll 30.
