The core 21 </ b> B is attached or detached, or the used pressure-sensitive adhesive sheet 21 </ b> A of the pressure-sensitive adhesive roll 21 set on the both roll support shafts 53 and 54 can be peeled and removed. That is, when the rotary cover 52 moves from the closed position to the open position, the rear edge portion of the rotary cover 52 opposite to the front edge flange is passed over the scraping body 16 and the contact rotating body 18, thereby scraping up. It is interposed between the body 16, the contact rotating body 18 and the adhesive roll 21. As a result, when the rotating cover 52 is opened, and the used one turn of the adhesive sheet 21A of the adhesive roll 21 set on both the support shafts 53 and 54 is peeled and removed, the adhesive sheet 21A is removed. The scraping body 16 and the contact rotating body 18 can be peeled smoothly without sticking to the outer periphery. The peeled end of the pressure-sensitive adhesive sheet 21 </ b> A can be cut using the front edge or the rear edge of the rotary cover 52.

Although the sub wiping member 62 may be provided over the entire width of the bottom surface 42, the resistance at the time of carpet cleaning is increased, and the above-described bottom surface 42 is provided only at the center of the bottom surface 42 so that the above-described bottom surface 42 does not contact the floor. Therefore, in this embodiment, it is provided only at the center of the bottom surface 42.
清掃具１０は、掻き上げ体１６の掻き上げ部１６Ｂのブラシの毛の長さを前述の如く5mm程度ばらつくように作ってあるから、掻き上げ部１６Ｂの一部の毛は塵取部３０の上ゴミ止め部３３に接触して抵抗を受け、またピックアップ部材４０のすくい面４１に接触して抵抗を受ける。清掃具１０の後進時には、前タイヤ１７が若干浮き、掻き上げ体１６を駆動する力が小さいため、掻き上げ部１６Ｂ（ブラシロール）は上記抵抗により回転しない。尚、清掃具１０の前進時には、前タイヤ１７に柄１１からの操作力が加わり、掻き上げ体１６を駆動する力が大きくなるため、掻き上げ部１６Ｂは上記抵抗に打ち勝って回転する。
Since the cleaning tool 10 is made so that the length of the brush hair of the scraping portion 16B of the scraping body 16 varies by about 5 mm as described above, some of the hair of the scraping portion 16B is part of the dust collecting portion 30. The upper dust stopper 33 comes into contact with the resistance, and the pick-up surface 41 of the pickup member 40 comes into contact with the resistance. When the cleaning tool 10 moves backward, the front tire 17 slightly floats and the force for driving the scraping body 16 is small, so the scraping portion 16B (brush roll) does not rotate due to the resistance. When the cleaning tool 10 moves forward, the operating force from the handle 11 is applied to the front tire 17 and the force for driving the scraping body 16 increases, so that the scraping portion 16B rotates to overcome the resistance.
清掃具１０のフローリング上での後進時には、掻き上げ部１６Ｂが回転しないので、上述の前進時に拭部材６１からすくい面４１の最下端部にかけて残ったほこりや小さなゴミが掻き上げ部１６Ｂの方へと移動し、掻き上げ部１６Ｂのブラシの間に絡む。従って、残ったほこりが床に筋状に残ることがない。また、掻き上げ部１６Ｂのブラシに絡んだほこりは次の前進時に掻き上げ体１６の回転とともに掻き上げられ、塵取部３０或いは粘着ロール２１に捕捉される。
When the cleaning tool 10 moves backward on the flooring, the scraping portion 16B does not rotate. Therefore, dust and small dust remaining from the wiping member 61 to the lowermost end portion of the scooping surface 41 during the above-described forward travel toward the scraping portion 16B. And entangled between the brushes of the scraping portion 16B. Therefore, the remaining dust does not remain streaks on the floor. Further, the dust entangled with the brush of the scraping portion 16B is scraped up with the rotation of the scraping body 16 at the next advance, and is captured by the dust collector 30 or the adhesive roll 21.
即ち、掻き上げ体１６は前タイヤ１７の回転によって回転する。後進時には、柄１１を引く力が働くため後進力が前タイヤ１７に伝わりにくい（前進時には柄１１からの押圧力がアーム軸を介して前タイヤ１７に伝わり、前タイヤ１７が強く清掃面にグリップして回転する）ため、前タイヤ１７が回転しにくい。その結果、掻き上げ体１６が回転しにくいから前進時に拭部材６１からすくい面４１の最下端部にかけて残ったゴミは掻き上げ体１６のブラシロールからなる掻き上げ部１６Ｂの方へ移動し、ブラシロールからなる掻き上げ部１６Ｂの毛の間にからむ。従って、後進時に残った上述のゴミが床にすじ状に残ることがない。ブラシロールからなる掻き上げ部１６Ｂの毛の間にからんだゴミは、次の前進時に、掻き上げられ、ゴミ受け部３１に捕集される。
That is, the scraper 16 is rotated by the rotation of the front tire 17. During reverse travel, the pulling force of the handle 11 is applied so that the reverse drive force is difficult to be transmitted to the front tire 17 (the forward pressure is transmitted from the handle 11 to the front tire 17 via the arm shaft during forward travel, and the front tire 17 is strongly gripped by the cleaning surface. Therefore, the front tire 17 is difficult to rotate. As a result, since the scraping body 16 is difficult to rotate, the dust remaining from the wiping member 61 to the lowermost end portion of the scooping surface 41 at the time of advance moves toward the scraping portion 16B composed of the brush roll of the scraping body 16, and the brush It is entangled between the hairs of the scraping portion 16B made of a roll. Therefore, the above-mentioned garbage remaining at the time of reverse travel does not remain in a streak shape on the floor. The dust entangled between the hairs of the scraping portion 16 </ b> B made of a brush roll is scraped up and collected by the dust receiving portion 31 at the next advancement.
清掃具１０のカーペットでの清掃時には、ピックアップ部材４０の底面４２のくぼみに接着されている拭部材６１、６２は、カーペットの毛にそれらの起毛を押されてなびき、抵抗は小さい。
When the cleaning tool 10 is cleaned with a carpet, the wiping members 61 and 62 adhered to the dents on the bottom surface 42 of the pickup member 40 are fluttered by the raised bristles of the carpet, and the resistance is small.
また、ピックアップ部材４０の底面４２は硬質プラスチックからなり、カーペットの毛がこの広い硬質底面４２を押し上げるから、ピックアップ部材４０が必要以上にカーペットに沈み込むことがなく、抵抗は小さい。尚、拭部材６１、６２の起毛とカーペットとの抵抗により、ピックアップ部材４０は適度な抵抗を受け、少しカーペットに沈むから、すくい面４１によりカーペット表面のゴミをすくい上げ易くなる。
Further, the bottom surface 42 of the pickup member 40 is made of hard plastic, and the hair of the carpet pushes up the wide hard bottom surface 42, so that the pickup member 40 does not sink more than necessary and the resistance is small. The pick-up member 40 receives an appropriate resistance due to the resistance between the raised brushes of the wiping members 61 and 62 and the carpet, and sinks slightly on the carpet. Therefore, the rake face 41 facilitates scooping up dust on the carpet surface.
清掃具１０にあっては、フレーム１５に対する掻き上げ体１６、接触回転体１８の支持構造を以下の如くにする。尚、掻き上げ体１６、接触回転体１８の支持構造は図４、図１０に示す如く、実質的に同じであり、接触回転体１８の支持構造を代表として説明する。

タイヤ１９は、図７に示す如く、ホイール７１の大径外輪部７１Ａの外周に嵌着される。ホイール７１は大径外輪部７１Ａの内周をタイヤベース８０の大径部８１の外周に回転可能に枢支されるとともに、中心支軸７１Ｂをタイヤベース８０の中心軸孔８２に回転可能に枢支される。ホイール７１の一側部には、ホイール７１をタイヤベース８０の大径部８１に対して抜け止めするロックリング７２が係止される。タイヤベース８０の中心軸孔８２に対する偏心位置に設けた偏心孔８３には小歯車７３が回転可能に枢支され、ホイール７１の大径外輪部７１Ａに対してタイヤベース８０の大径部８１を介する内周側には内歯車７１Ｃが形成され、小歯車７３を内歯車７１Ｃに噛合いさせている。タイヤ１９及びホイール７１の回転により、内歯車７１Ｃと小歯車７３の噛合いを介して、小歯車７３が増速回転せしめられるものである。接触回転体１８の回転軸１８Ａは、タイヤベース８０の偏心孔８３から小歯車７３の中空係合部７３Ａに係着される。
As shown in FIG. 7, the tire 19 is fitted on the outer periphery of the large-diameter outer ring portion 71 </ b> A of the wheel 71. The wheel 71 is pivotally supported so that the inner periphery of the large-diameter outer ring portion 71A can rotate on the outer periphery of the large-diameter portion 81 of the tire base 80, and the center support shaft 71B can be pivoted to the center shaft hole 82 of the tire base 80. Be supported. On one side of the wheel 71, a lock ring 72 that holds the wheel 71 against the large-diameter portion 81 of the tire base 80 is engaged. A small gear 73 is rotatably supported in an eccentric hole 83 provided at an eccentric position with respect to the central shaft hole 82 of the tire base 80, and the large diameter portion 81 of the tire base 80 is connected to the large diameter outer ring portion 71 </ b> A of the wheel 71. An internal gear 71C is formed on the inner peripheral side through which the small gear 73 is engaged with the internal gear 71C. The rotation of the tire 19 and the wheel 71 causes the small gear 73 to rotate at an increased speed through the meshing of the internal gear 71 </ b> C and the small gear 73. The rotating shaft 18 </ b> A of the contact rotating body 18 is engaged with the hollow engagement portion 73 </ b> A of the small gear 73 from the eccentric hole 83 of the tire base 80.
タイヤベース８０は、図７に示す如く、大径部８１の側傍に環状取付座８４を備え、この取付座８４から突出する円形状挿入部８５を、フレーム１５に貫通させた固定孔１５Ａにフレーム１５の外側から挿入する。タイヤベース８０の挿入部８５とフレーム１５の固定孔１５Ａとは、挿入部８５に設けた凹部と固定孔１５Ａに設けた凸部により、タイヤ１９の回転方向に対して凹凸係合する。
As shown in FIG. 7, the tire base 80 includes an annular mounting seat 84 on the side of the large-diameter portion 81, and a circular insertion portion 85 protruding from the mounting seat 84 is formed in the fixing hole 15 </ b> A penetrating the frame 15. Insert from the outside of the frame 15.

タイヤベース８０は挿入部８５から突出する係止部８６を有し、係止部８６をフレーム１５の内側に臨ませる。タイヤベース８０の係止部８６には、固定クリップ９０の係止部９１が差し込まれて係入する。固定クリップ９０の係止部９１をタイヤベース８０の係止部８６に係入したとき、タイヤベース８０の挿入部８５まわりの取付座８４は固定孔１５Ａの外側の外縁に引き寄せられて外縁の全周に密着するように当たり、固定クリップ９０の円形状外周部９２は固定孔１５Ａの内側の外縁に密着するように当たり、タイヤベース８０をフレーム１５に固定する。尚、タイヤベース８０と固定クリップ９０との密着安定性の観点から、固定孔１５Ａはタイヤベース８０の大径部８１よりやや小径に設けられることが好ましい。また、固定クリップ９０、及びタイヤベース８０、本体フレーム１５は合成樹脂で成形すると、本体フレーム１５とタイヤベース８０の係止部８６との隙間を固定クリップ９０の厚みよりやや狭く設計することで、本体フレーム１５とタイヤベース８０と固定クリップ９０の各合成樹脂の弾発力によって、より強固な密着性を得ることができる。
The tire base 80 has a locking portion 86 protruding from the insertion portion 85, and the locking portion 86 faces the inside of the frame 15. The locking portion 91 of the fixing clip 90 is inserted into and engaged with the locking portion 86 of the tire base 80. When the locking portion 91 of the fixing clip 90 is engaged with the locking portion 86 of the tire base 80, the mounting seat 84 around the insertion portion 85 of the tire base 80 is drawn to the outer edge outside the fixing hole 15A, and the entire outer edge is drawn. The circular outer peripheral portion 92 of the fixing clip 90 comes into close contact with the outer periphery of the fixing hole 15 </ b> A and fixes the tire base 80 to the frame 15. In addition, from the viewpoint of adhesion stability between the tire base 80 and the fixing clip 90, the fixing hole 15 </ b> A is preferably provided with a slightly smaller diameter than the large diameter portion 81 of the tire base 80. Further, when the fixing clip 90, the tire base 80, and the main body frame 15 are formed of synthetic resin, the gap between the main body frame 15 and the locking portion 86 of the tire base 80 is designed to be slightly narrower than the thickness of the fixing clip 90. Due to the elastic force of each synthetic resin of the main body frame 15, the tire base 80, and the fixing clip 90, stronger adhesion can be obtained.
タイヤベース８０の係止部８６は、タイヤベース８０の軸方向視で中心軸孔８２と偏心孔８３を囲むＵ字状溝８６Ａを有し、固定クリップ９０の係止部９１は、係止部８６のＵ字状溝８６Ａに一方から係入するＵ字状突部９１Ａを有する。Ｕ字状突部９１ＡのＵ字の両端には、固定クリップ９０の係止部８６への差し込み端でＵ字状溝８６ＡのＵ字の両端に係合する突起状爪が設けられ、固定クリップ９０の抜け止めを図っている。

尚、清掃具１０は前進だけでなく、後進もできる。
清掃具１０にあっては、（Ａ）掻き寄せ体１００の構造、（Ｂ）接触回転体１８と回転軸１８Ａを被覆するカバー１１０、１２０の構造を以下の如くに有する。
The cleaning tool 10 can move not only forward but also backward.
The cleaning tool 10 has (A) the structure of the scraper 100 and (B) the structures of the covers 110 and 120 that cover the contact rotating body 18 and the rotating shaft 18A as follows.
（Ａ）掻き寄せ体１００の構造（図２、図３、図８〜図１３）
清掃具１０は、図２、図３に示す如く、フレーム１５の前縁両側部で、掻き上げ体１６の前方及び側方の近傍に掻き寄せ体としての掻き寄せブラシ体１００を配置してある。ブラシ体１００は、床面上を清掃具１０の側方から前方を経由して内側方向へ回転し、前タイヤ１７の存在によって掻き上げ体１６が及ばない清掃具１０の側方、及び掻き上げ体１６の前方の掻き上げ力が及ばない範囲にあるゴミを捕集する。
(A) Structure of scraper 100 (FIGS. 2, 3, and 8 to 13)
As shown in FIGS. 2 and 3, the cleaning tool 10 has a scraping brush body 100 as a scraping body disposed on both sides of the front edge of the frame 15 in the vicinity of the front side and the side of the scraping body 16. . The brush body 100 rotates on the floor surface from the side of the cleaning tool 10 to the inside through the front, and the side of the cleaning tool 10 that does not reach the scooping body 16 due to the presence of the front tire 17 and the scooping up. Collects garbage in a range where the scraping force in front of the body 16 does not reach.
ブラシ体１００は、図８〜図１２に示す如く、フレーム１５の前縁両側部にて鉛直軸まわりに回転可能に枢支される従動プーリ１０１の外周の周方向多数位置に取着された多数のブラシ（毛束）１０２により構成される。このとき、前タイヤ１７のタイヤベース８０の偏心孔８３には駆動プーリ１０３の中空係合部１０３Ａが挿着され、駆動プーリ１０３の中空係合部１０３Ａは小歯車７３の中空係合部７３Ａとそれらの半割筒部同士を相嵌合させて回転方向に係合する。これにより、前タイヤ１７の回転が増速されて駆動プーリ１０３に伝達される。掻き上げ体１６の回転軸１６Ａが駆動プーリ１０３の中空係合部１０３Ａを素通りし、小歯車７３の中空係合部７３Ａに係着せしめられる。ブラシ体１００の従動プーリ１０１とタイヤ１７の側の駆動プーリ１０３には、Ｏリングからなる巻掛ベルト１０４が巻掛けられる。駆動プーリ１０３及び巻掛ベルト１０４は、フレーム１５に着脱される被覆体１０５により被覆される。これにより、ブラシ体１００は、清掃具１０が床面上を前進するときのタイヤ１７の回転力により、床面に沿う水平面内で前述の回転方向に回転せしめられる。タイヤ１７の回転力はギヤ等を介してブラシ体１００に伝達されても良いが、ギヤ等はほこりで回転しなくなるので、Ｏリングが好ましい。
As shown in FIGS. 8 to 12, the brush body 100 is attached to a large number of circumferential positions on the outer periphery of the driven pulley 101 that is pivotally supported around the vertical axis on both sides of the front edge of the frame 15. Brush (hair bundle) 102. At this time, the hollow engagement portion 103A of the drive pulley 103 is inserted into the eccentric hole 83 of the tire base 80 of the front tire 17, and the hollow engagement portion 103A of the drive pulley 103 is connected to the hollow engagement portion 73A of the small gear 73. These half cylinder parts are phase-fitted and engaged in the rotational direction. Thereby, the rotation of the front tire 17 is accelerated and transmitted to the drive pulley 103. The rotary shaft 16A of the scraping body 16 passes through the hollow engagement portion 103A of the drive pulley 103 and is engaged with the hollow engagement portion 73A of the small gear 73. A winding belt 104 made of an O-ring is wound around the driven pulley 101 of the brush body 100 and the driving pulley 103 on the tire 17 side. The drive pulley 103 and the wrapping belt 104 are covered with a covering 105 that is attached to and detached from the frame 15. Thereby, the brush body 100 is rotated in the above-described rotation direction within a horizontal plane along the floor surface by the rotational force of the tire 17 when the cleaning tool 10 moves forward on the floor surface. Although the rotational force of the tire 17 may be transmitted to the brush body 100 via a gear or the like, an O-ring is preferable because the gear or the like does not rotate due to dust.
ブラシ体１００は、ブラシ１０２をプーリ１０１の外周に沿って間欠的に設けることで、床面上のゴミを掻き寄せ可能にする。ブラシ１０２をプーリ１０１の全周に連続的に設ける場合には、床面上のゴミを接線方向に弾いてしまう。
The brush body 100 can scrape dust on the floor surface by providing the brush 102 intermittently along the outer periphery of the pulley 101. When the brush 102 is continuously provided on the entire circumference of the pulley 101, dust on the floor surface is flipped in the tangential direction.
ブラシ体１００は、ブラシ１０２を床面に沿う水平面に対して30度〜60度の角度をなすように延在させ、又はプーリ１０１の鉛直回転軸に対して30度〜60度の角度をなすように延在させ、結果として、タイヤ１７を床面に設置させた清掃時にブラシ１０２が撓み、ブラシ１０２の先端が床面の溝の底まで届き易くなる。
The brush body 100 extends the brush 102 so as to form an angle of 30 degrees to 60 degrees with respect to a horizontal plane along the floor surface, or forms an angle of 30 degrees to 60 degrees with respect to the vertical rotation axis of the pulley 101. As a result, the brush 102 bends during cleaning with the tire 17 placed on the floor surface, and the tip of the brush 102 can easily reach the bottom of the groove on the floor surface.
ブラシ体１００は、平面視でブラシ１０２の回転によって描かれる仮想円の領域内に、タイヤ１７の一部が重なるようにする。これにより、ブラシ体１００をタイヤ１７に非常に近い位置に配置し、清掃具１０をコンパクト化できる。また、タイヤ１７の前方の床面上に、ブラシ体１００が掻き寄せたゴミを残すスペースをなくすことができる。
The brush body 100 is configured such that a part of the tire 17 overlaps an area of a virtual circle drawn by the rotation of the brush 102 in a plan view. Thereby, the brush body 100 can be arrange | positioned in the position very close to the tire 17, and the cleaning tool 10 can be compactized. Further, it is possible to eliminate a space for leaving the dust scraped by the brush body 100 on the floor surface in front of the tire 17.
ブラシ体１００は、ブラシ１０２がタイヤ１７に接触するようにする。これにより、タイヤ１７の表面に付着したほこりをブラシ体１００によって除去し、タイヤ１７の表面を正常に保つ。
The brush body 100 causes the brush 102 to contact the tire 17. Thereby, the dust adhering to the surface of the tire 17 is removed by the brush body 100, and the surface of the tire 17 is kept normal.
ブラシ体１００は、平面視でブラシ１０２の回転によって描かれる仮想円の領域内に掻き上げ体１６の掻き上げ部１６Ｂの一部が重なるようにする。これにより、ブラシ１０２が掻き寄せたゴミを掻き上げ体１６により漏らさず掻き上げできる。
The brush body 100 is configured such that a part of the scraping portion 16B of the scraping body 16 overlaps an area of a virtual circle drawn by the rotation of the brush 102 in a plan view. Thereby, the dust scraped by the brush 102 can be scraped up without being leaked by the scraper 16.
ブラシ体１００は、平面視でブラシ１０２の回転によって描かれる仮想円の一部が、平面視でブラシ体１００を除く清掃具１０に外接する矩形の前角より突出するようにする。ブラシ１０２の仮想円の一部が上述の如くに突出する長さは、ブラシ体１００の中心（プーリ１０１の回転軸）から上述の矩形領域までの長さに対し、概ね2倍〜10倍とする。清掃具１０が壁の際で床面を清掃するとき、ブラシ体１００のブラシ１０２が突出しているから、壁際にブラシ１０２の毛が当たり、ブラシ１０２の撓み弾性力によって壁際のゴミを掻き寄せ、掻き上げ体１６の前方近傍まで誘導する。特に、従来の清掃具では捕集が困難であった２つの壁が直角をなすコーナー部分にあるゴミも掻き上げ体１６の前方近傍に掻き寄せ可能になる。
The brush body 100 is configured such that a part of a virtual circle drawn by the rotation of the brush 102 in a plan view protrudes from a rectangular front corner circumscribing the cleaning tool 10 excluding the brush body 100 in a plan view. The length at which a part of the virtual circle of the brush 102 protrudes as described above is approximately 2 to 10 times the length from the center of the brush body 100 (the rotation axis of the pulley 101) to the rectangular region described above. To do. When the cleaning tool 10 cleans the floor surface against the wall, the brush 102 of the brush body 100 protrudes, so that the hair of the brush 102 hits the wall and scrapes the dust near the wall by the bending elastic force of the brush 102, Guide to the vicinity of the front of the scraped body 16. In particular, the dust at the corner portion where the two walls form a right angle, which has been difficult to collect with the conventional cleaning tool, can be scraped to the vicinity of the front of the scooping body 16.
ブラシ体１００は、平面視でブラシ１０２の回転によって描かれる仮想円の径を、プーリ１０１の径の概ね3倍〜10倍とする。ブラシ１０２の長さがプーリ１０１の径に比較して長いから、ゴミ捕集領域が広く、床面上で清掃できないデッドスペースを少なくできる。
In the brush body 100, the diameter of a virtual circle drawn by the rotation of the brush 102 in plan view is approximately 3 to 10 times the diameter of the pulley 101. Since the length of the brush 102 is longer than the diameter of the pulley 101, the dust collection area is wide, and the dead space that cannot be cleaned on the floor surface can be reduced.
ブラシ体１００は、プーリ１０１に多数のブラシ１０２を取着する場合、図１３に示す如く、清掃具１０を床面に非接触とする状態で、ブラシ１０２の先端がタイヤ１７の底部より床面方向に突出するようにする。タイヤ１７が床面に接触した状態で、ブラシ１０２が撓むまで、ブラシ１０２の撓み弾性力によってゴミを効率良く掻き寄せる。床面の溝の底までブラシ１０２が届く。
When the brush body 100 has a large number of brushes 102 attached to the pulley 101, the tip of the brush 102 is placed on the floor surface from the bottom of the tire 17 in a state where the cleaning tool 10 is not in contact with the floor surface as shown in FIG. Project in the direction. In a state where the tire 17 is in contact with the floor surface, dust is efficiently scraped by the bending elastic force of the brush 102 until the brush 102 is bent. The brush 102 reaches the bottom of the floor groove.
本実施例によれば以下の作用効果を奏する。
(a)平面視でタイヤ１７がブラシ体１００の回転によって描かれる仮想円の領域内に配置される。ブラシ体１００をタイヤ１７に非常に近い位置に配置したから、清掃具１０をコンパクト化できる。
According to the present embodiment, the following operational effects can be obtained.
(a) The tire 17 is arranged in a region of a virtual circle drawn by the rotation of the brush body 100 in plan view. Since the brush body 100 is disposed at a position very close to the tire 17, the cleaning tool 10 can be made compact.
