これまで、床を清掃するために各種の手押し型クリーナーが提供されているが、いずれのクリーナーも自由な操作が難しく、また不使用中の収納においては嵩張る点が難点であった。また、装置内部に貯えたゴミを簡単に出して捨てることができず、クリーナー自体の清潔を保つにも洗浄や清掃し難いなど、総体としていずれも使い勝手が良くなく、一般に普及するには至っていない。
【０００３】
また、構造が複雑だったり壊れやすいなどの欠点を有するものが多かった。
特に、クリーナーとしての本来の目的である奇麗に清掃することについては、これまでのものは、殆どが表面のゴミの多くを素通りしてしまい、満足のいくものではなかった。
【０００４】
【発明が解決しようとする課題】
本発明は、上記実情に鑑みてなされたもので、床面を奇麗に清掃することができて集めたゴミを出して捨てるのも容易で、また狭い隙間にも収納でき且つ壊れにくく、だれでも軽く操作でき、使い勝手の優れた手押し型のクリーナーを提供するものである。
【０００５】
【課題を解決するための手段】
上記課題を解決するために、本発明の手押し型ローラー刷毛クリーナーは、ゴミを受ける前箱体１と、ローラー刷毛９を内蔵し且つ上方斜め後方に突き出した手押し棒１２を備えた後箱体２とが着脱機構３を介して分離可能に合体させられるようにする。
【０００６】
前記前箱体１には最前部に前車輪４，４を装着するとともにその箱底１ａの連結側辺縁１ｂにゴミ誘導板５の基端辺部５ｂを先端辺縁５ａが床面Ｆに接するように下方に向けて設ける。
【０００７】
前記後箱体２には、後部両側壁面２ａ，２ａに設けた軸受部６にゴムタイヤ７ｂを装着した後車輪７の軸７ａを軸承し、また中央側壁面２ｂ，２ｂに設けた長孔を斜め後下がりに開口した左右対称な軸受孔８にローラー刷毛９の軸９ａを軸承し、その軸９ａの両外端にＶ溝従動輪１０を固着して、前記ローラー刷毛９の軸９ａが前記軸受孔８の後下部に位置した時に前記ゴムタイヤ７ｂの側面７ｃがそのＶ溝従動輪１０のＶ溝１１に接するように構成される。
【０００８】
そして、前記後車輪７が後退方向に回転すると前記ローラー刷毛９の軸９ａが軸受孔８内を前上部に斜めに競り上がって前記ローラー刷毛９が床面から離れる方向に進み、前記後車輪７が前進方向に回転すると前記ローラー刷毛９の軸９ａが軸受孔８内を斜めに降下して床面に押圧されつつ前記ゴムタイヤ７ｂの側面７ｃがＶ溝従動輪１０のＶ溝１１面に接して前記ゴムタイヤ７ｂからＶ溝従動輪１０へ回転が伝達されるように構成された手押し型ローラー刷毛クリーナーである。
【０００９】
また、上記構成において、前記手押し棒１２が、全体の長さを調節する伸縮手段１３と、床に対して斜め後方に角度調節可能とする角度調節手段１４とを備えたことを特徴とするものである。
【００１０】
さらに、上記構成において、前記前箱体１に、持ち運び用の把手１５を設けて成るものである。
【００１１】
さらにまた、上記構成において、前記前車輪４を、方向自在なキャスター１６とするものである。
【００１２】
【発明の実施の形態】
本発明の実施の形態について以下図で説明する。
本発明の手押し型ローラー刷毛クリーナーは、図１に示すように、ゴミを受ける前箱体１と、ローラー刷毛９を内蔵し且つ上方斜め後方に突き出したグリップ１７付き手押し棒１２を備えた後箱体２とが着脱機構３により合体と分離ができるようにしてある。
【００１３】
前記着脱機構３は、図２及び図３に示すように、前箱体１の後部両側壁面に側方に向けて突起２２を固設し、後箱体２の前部両側壁面にフック２３を設けて前記突起２２に掛けて連結し、前箱体１の後部上壁面と後箱体２の前部上壁面とを連結板２４を介してボルト２５で固定できるようにしたものが可能である。
前記前箱体１と後箱体２とは、金属製、木製、プラスチック製などが使用できるが、強度、耐久性などからステンレスなどの難腐食製の金属板で形成すると良い。
【００１４】
前記グリップ１７付き手押し棒１２は、図１に示すように、鞘筒内に挿入した中軸を出没させて全体の長さ変えて所望長さにネジ１８で締め付け固定できるようにした伸縮手段１３と、図１及び２に示すように、手押し棒１２の基部を後箱体２の上部に前後角度の調節可能に枢支し、後箱体２の後端部に支持棒１９の基部を前後角度の調節可能に枢支するとともにその支持棒の上端部に手押し棒１２を上下にスライドするスライド環２０を装着して、手押し棒１２を所望角度にしてネジ２１で締め付け固定することによって、床に対して斜め後方に角度調節可能とする角度調節手段１４とを備える。
【００１５】
前記前箱体１には、図１及び図３に示すように、最前部に前車輪４，４を装着する。
また、その箱底１ａの連結側辺縁１ｂにゴミ誘導板５の基端辺部５ｂを、先端辺縁５ａが床面Ｆに接するように下方に向けて固定する。
そのゴミ誘導板５は板ゴムや柔軟樹脂板を用いて常に床面Ｆに密接するようにする。そして箱底１ａに対しては、ゴミ誘導板５の先端辺縁などが摩耗損傷したときに別のものと交換できるように、ボルトなどで着脱可能に固定する。
前記前車輪４は、方向自在なキャスター１６とすると移動させたいと思う方向に操作が軽くできて良い。
【００１６】
前記後箱体２には、図１、図３及び図４に示すように、後部両側壁面２ａ，２ａに設けた軸受部６にゴムタイヤ７ｂを装着した後車輪７の軸７ａを軸承する。
【００１７】
そして、図５に示すように、中央側壁面２ｂ，２ｂに設けた長孔を斜め後下がりに開口した左右対称な軸受孔８に、ローラー刷毛９の軸９ａをその刷毛先端の最下部が前記後車輪７の外周面の最下部よりも下方になるように軸承し、図４に示すように、その軸９ａの両外端に両側面に外開き円盤を対向させてＶ溝１１を形成したＶ溝伝動輪１０を固着して、前記ローラー刷毛９の軸９ａが前記軸受孔８の後下部に位置した時に前記ゴムタイヤ７ｂの側面７ｃがそのＶ溝従動輪１０のＶ溝１１面に接するようにする。
即ち、前記ゴムタイヤ７ｂのトレッド面がゴミなどで汚れたとしても、Ｖ溝従動輪１０側へはその汚れが全く移らなず、Ｖ溝従動輪１０が汚れない利点がある。
【００１８】
前記前箱体１の上には、持ち運び用の把手１５を設けるとゴミ捨てが楽である。
【００１９】
【作用】
本発明は上記構成なので、図６に示すように、後車輪７が後退方向に回転すると、前記後車輪７にローラー刷毛９の軸９ａに固定されているＶ溝従動輪１０が押され、その軸９ａが軸受孔８に案内されてその軸受孔８の前上部に向かって斜めに競り上がり、前記ローラー刷毛９が床面から離れる方向に進む。そしてさらに、押さえ付けられていた前記ローラー刷毛９が刷毛の弾力により反発して刷毛外周先端が床面Ｆに接する状態まで競り上げられる。そしてこのときはＶ溝従動輪１０は後車輪７から離された状態（空回り状態）となっている。
【００２０】
また、図５に示すように、クリーナーを前進させると、床面Ｆの抵抗で前記ローラー刷毛９の軸９ａが軸受孔８内を斜め後ろに降下して行き、前記後車輪７の前進方向の回転によって、前記ゴムタイヤ７ｂの側面７ｃがそのＶ溝従動輪１０のＶ溝１１面に接して前記ゴムタイヤ７ｂからＶ溝従動輪１０へ回転が伝達され、さらに軸受孔８に沿ってローラー刷毛９を巻き込むように押し下げて、刷毛外周先端を床面に押圧しつつ回転する。この時ローラー刷毛９の先端が進行方向にゴミを撥ね上げるように回転し、撥ね上げられたゴミはゴミ誘導板５上を案内されて前箱体１の空間内にかき集められる。
【００２１】
【発明の効果】
本発明は、以上説明したように、手押し棒１２のグリップ１７を握って前へ押して前進させると、ゴムタイヤ７ｂからＶ溝従動輪１０へ回転が伝達されてローラー刷毛９がゴミをゴミ誘導板５上に撥ね上げるようにかき集めるので床面を奇麗に清掃することができる。
【００２２】
また、手押し棒１２を引いて後退させると、ローラー刷毛９の軸９ａが軸受孔８内を前上部に斜めに競り上がってＶ溝従動輪１０がゴムタイヤ７ｂから離れて空回りするので、ゴミの後ろへの撥ね上げが起こらず、また殆どローラー刷毛９による抵抗を感じないで楽に後退させることができる。
また前車輪４をキャスター１６とすることにより、後車輪を少し浮かせれば自由に小回りが利き、どの方向への転換も大変に軽く楽にできる。
【００２３】
前箱体１内に集めたゴミを出して捨てる際には、ゴミを入れる前箱体１が重たい後箱体２と分離されるので軽く扱えるようになり、また把手１５により持ち運びしもし易い。
この分離した前箱体１のみでは、箒などで清掃する場合のチリトリとして利用できる利点もある。
【００２４】
また、グリップ１７付き手押し棒１２は、全体の長さを調節する伸縮手段１３と、床に対して斜め後方に角度調節可能とする角度調節手段１４とを備えた形態では、手押し棒１２の長さを短くもでき、また角度を床に平行にまですることができ、その状態で起こして立て掛ければ、縦に狭い隙間にも収納することができる。
また手押し棒１２の角度を床に垂直にして立てて隅に寄せて置けば、あまり邪魔にならなず、ゴミを散らかした時に即応して清掃することができる。
【００２５】
さらにチェーンやギヤーが全くない簡潔な構造なので長期間殆ど壊れることがない。またクリーナー本体の水洗いも前箱体１と後箱体２とを分離して内部まで簡単に行うことができる。
以上が総合されて大変に使い勝手の優れた機能的なクリーナーが完成した。

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the hand-type roller brush cleaner of the present invention includes a front box 1 for receiving dust, and a rear box including a roller 17 and a hand bar 12 with a grip 17 that protrudes obliquely upward and rearward. The body 2 can be separated and combined by the attaching / detaching mechanism 3.
[0013]
As shown in FIGS. 2 and 3, the attachment / detachment mechanism 3 has protrusions 22 fixed laterally on both side walls of the rear part of the front box 1, and hooks 23 are attached to both side walls of the front part of the rear box 2. It is possible to connect and hang on the projection 22 so that the rear upper wall surface of the front box body 1 and the front upper wall surface of the rear box body 2 can be fixed by the bolt 25 via the connecting plate 24. .
The front box body 1 and the rear box body 2 can be made of metal, wood, plastic, or the like, but are preferably formed of a corrosion-resistant metal plate such as stainless steel from the viewpoint of strength and durability.
[0014]
As shown in FIG. 1, the hand bar 12 with the grip 17 includes an expansion / contraction means 13 that can be fixed by tightening a screw 18 to a desired length by projecting and retracting a central shaft inserted into a sheath tube. 1 and 2, the base of the hand bar 12 is pivotally supported on the upper portion of the rear box 2 so that the front and rear angles can be adjusted, and the base of the support bar 19 is mounted on the rear end of the rear box 2 with the front and rear angles. A slide ring 20 that slides the hand bar 12 up and down is attached to the upper end of the support bar, and the hand bar 12 is tightened and fixed with a screw 21 at a desired angle. On the other hand, angle adjusting means 14 that can adjust the angle obliquely rearward is provided.
[0015]
As shown in FIGS. 1 and 3, front wheels 4 and 4 are attached to the front box 1 at the foremost part.
Further, the base end side 5b of the dust guide plate 5 is fixed to the connecting side edge 1b of the box bottom 1a so that the front end edge 5a is in contact with the floor surface F.
The dust guide plate 5 is always in close contact with the floor surface F using a rubber plate or a flexible resin plate. The box bottom 1a is detachably fixed with a bolt or the like so that the tip edge of the dust guide plate 5 can be replaced with another one when worn or damaged.
The front wheel 4 may be lightly operated in the direction in which it is desired to move if it is a directional caster 16.
[0016]
As shown in FIGS. 1, 3 and 4, the rear box body 2 supports a shaft 7 a of a rear wheel 7 in which a rubber tire 7 b is attached to a bearing portion 6 provided on the rear side wall surfaces 2 a and 2 a.
[0017]
Then, as shown in FIG. 5, the shaft 9a of the roller brush 9 is placed in the left and right symmetrical bearing hole 8 in which the long holes provided in the central side wall surfaces 2b and 2b are opened obliquely backward and downward, and the lowermost part of the brush tip is the above-mentioned Bearings were made so that they were below the lowermost part of the outer peripheral surface of the rear wheel 7, and as shown in FIG. 4, V-grooves 11 were formed on both outer ends of the shaft 9a with facing discs facing both sides. When the V-groove transmission wheel 10 is fixed and the shaft 9a of the roller brush 9 is positioned at the rear lower part of the bearing hole 8, the side surface 7c of the rubber tire 7b is in contact with the V-groove 11 surface of the V-groove driven wheel 10. To.
That is, even if the tread surface of the rubber tire 7b is contaminated with dust or the like, there is an advantage that the dirt does not move to the V-groove driven wheel 10 side and the V-groove driven wheel 10 is not contaminated.
[0018]
If a handle 15 for carrying is provided on the front box 1, it is easy to throw away trash.
[0019]
[Action]
Since the present invention has the above-mentioned configuration, as shown in FIG. 6, when the rear wheel 7 rotates in the backward direction, the V-groove driven wheel 10 fixed to the shaft 9a of the roller brush 9 is pushed to the rear wheel 7, The shaft 9a is guided by the bearing hole 8 and abuts diagonally toward the front upper part of the bearing hole 8, and the roller brush 9 advances in a direction away from the floor surface. Further, the roller brush 9 that has been pressed down is repelled by the elasticity of the brush, and the brush outer peripheral tip is auctioned up to a state where it contacts the floor surface F. At this time, the V-groove driven wheel 10 is separated from the rear wheel 7 (idle state).
[0020]
Further, as shown in FIG. 5, when the cleaner is advanced, the shaft 9a of the roller brush 9 descends obliquely backward in the bearing hole 8 due to the resistance of the floor F, and the rear wheel 7 moves in the forward direction. The rotation causes the side surface 7c of the rubber tire 7b to contact the surface of the V-groove 11 of the V-groove driven wheel 10 so that the rotation is transmitted from the rubber tire 7b to the V-groove driven wheel 10, and the roller brush 9 is moved along the bearing hole 8. It is pushed down so as to be wound, and rotates while pressing the outer peripheral tip of the brush against the floor surface. At this time, the tip of the roller brush 9 rotates to repel dust in the traveling direction, and the repelled dust is guided on the dust guide plate 5 and collected in the space of the front box 1.
[0021]
【The invention's effect】
As described above, according to the present invention, when the grip 17 of the push bar 12 is grasped and pushed forward, the rotation is transmitted from the rubber tire 7b to the V-groove driven wheel 10 so that the roller brush 9 removes dust and the dust guide plate 5. The floor surface can be cleaned cleanly because it is gathered up so that it repels up.
[0022]
Further, when the push bar 12 is pulled and retracted, the shaft 9a of the roller brush 9 competes obliquely upward in the front of the bearing hole 8 and the V-groove driven wheel 10 moves away from the rubber tire 7b, so that the rear of the dust No repelling occurs, and the roller brush 9 can be easily moved back without feeling any resistance.
Further, by using the front wheel 4 as the caster 16, if the rear wheel is lifted slightly, a small turn can be freely made, and the change in any direction can be very light and easy.
[0023]
When the trash collected in the front box body 1 is taken out and discarded, the front box body 1 into which the trash is put is separated from the heavy rear box body 2 so that it can be handled lightly and is easily carried by the handle 15.
Only the separated front box 1 has an advantage that it can be used as a dust when cleaning with a scissors or the like.
[0024]
Further, the hand bar 12 with the grip 17 has a length of the hand bar 12 in a form including the expansion / contraction means 13 for adjusting the entire length and the angle adjusting means 14 for adjusting the angle obliquely backward with respect to the floor. The height can be shortened, and the angle can be parallel to the floor. If it is raised in this state and stood, it can be stored in a narrow gap vertically.
Also, if the hand bar 12 is set to be perpendicular to the floor and placed close to the corner, it does not get in the way and can be cleaned immediately when dust is scattered.
[0025]
Furthermore, since it has a simple structure with no chain or gear, it will hardly break for a long time. Also, the cleaner body can be washed with water easily by separating the front box 1 and the rear box 2.
As a result, a functional cleaner with excellent usability was completed.
