本発明は、次のような著大な効果を奏する。
本発明に係る清掃用具によれば、指を２本以上使って清掃シートを押し込み保持し、そのシートを噛み込むことのできる範囲が広いので確実に保持でき、かつ、その範囲に渡って均等に保持力を発揮できる。これにより、清掃シートに作用する引張力が大きい場合でも、清掃シートが清掃用具から外れる虞れがない。 The present invention has the following remarkable effects.
According to the cleaning tool of the present invention, the cleaning sheet is pushed and held by using two or more fingers, and the range in which the sheet can be bitten is wide, so that it can be securely held, and evenly over the range. The holding power can be demonstrated. Thereby, even when the tensile force which acts on a cleaning sheet is large, there is no possibility that a cleaning sheet may come off from a cleaning tool.

以下、実施の形態に示す図面に基づき本発明を詳説する。
図１〜図13に於て、本発明の実施の一形態を示し、20は清掃用具であり、清掃用具20は、把持杆13と、ジョイント14と、清掃用具本体１と、から成る。左右方向に長い矩形の清掃用具本体１は、巻付板25とクッション部材24から成っている。把持杆13は、延伸収縮可能であり、ジョイント14を介して上記巻付板25に取り付けられている。上記ジョイント14は、上記巻付板25の上面の中心付近に間隔を介して互いに対向するように立設された２つの支持部15，15と、この支持部15，15の間に枢着された筒状の回動部材16と、一端が二股に分岐すると共に上記回動部材16に揺動可能に取り付けられた揺動部材17と、から成る。該揺動部材17の他端は、上記把持杆13の下端に付設されている。回動部材16の回動軸と揺動部材17の揺動軸は直交して設けられており、すなわち、把持杆13は、前後左右に揺動可能となっている。また、ジョイント14は、把持杆13をさらに軸廻りに回転可能にするボールジョイントであってもよい。 Hereinafter, the present invention will be described in detail with reference to the drawings shown in the embodiments.
1 to 13 show an embodiment of the present invention, in which 20 is a cleaning tool, and the cleaning tool 20 includes a gripping rod 13, a joint 14, and a cleaning tool body 1. A rectangular cleaning tool main body 1 that is long in the left-right direction includes a winding plate 25 and a cushion member 24. The gripping rod 13 can be stretched and contracted, and is attached to the winding plate 25 via the joint 14. The joint 14 is pivotally mounted between two support portions 15 and 15 erected so as to be opposed to each other with a gap in the vicinity of the center of the upper surface of the winding plate 25. And a swinging member 17 which is bifurcated at one end and swingably attached to the rotating member 16. The other end of the swing member 17 is attached to the lower end of the gripping bar 13. The pivot shaft of the pivot member 16 and the pivot shaft of the pivot member 17 are provided orthogonal to each other, that is, the gripping rod 13 can swing back and forth and right and left. Further, the joint 14 may be a ball joint that allows the gripping rod 13 to further rotate around the axis.

さらに、図５に示すように、把持杆13の揺動範囲を広くするために、上記揺動部材17の揺動中心点19は、上記回動部材16の回動中心点18の位置よりも高い位置に配置されている。例えば、上下間隔の狭い空間に上記清掃用具本体１を突入させ清掃する際や、清掃者の立ち位置から離れた場所を清掃する際に把持杆13を揺動しても、上記揺動部材17が支持部15や巻付板25の上面に接触しにくくなっている。これによって、把持杆13を床面ぎりぎりまで（水平状にまで）倒して、狭小空間へ清掃用具本体１を差込む等の作業が可能となって至便である。また、清掃用具本体１の厚みは、前端・後端の方向に向かって薄くなるように形成され、上下間隔の狭い空間（狭小空間）に本体１を突入させやすくなっている。 Further, as shown in FIG. 5, in order to widen the swing range of the gripping rod 13, the swing center point 19 of the swing member 17 is larger than the position of the pivot center point 18 of the swing member 16. It is placed at a high position. For example, the rocking member 17 may be swung even when the gripper 13 is swung when the cleaning tool main body 1 is inserted into a space with a narrow vertical distance for cleaning, or when cleaning a place away from the standing position of the cleaner. However, it is difficult to contact the upper surface of the support portion 15 and the winding plate 25. As a result, it is possible to perform operations such as tilting the gripping rod 13 to the very bottom (horizontally) and inserting the cleaning tool main body 1 into a narrow space. The thickness of the cleaning tool main body 1 is formed so as to be thinner toward the front end and the rear end, so that the main body 1 can easily enter into a space (narrow space) having a narrow vertical interval.

図13に於て、上記把持杆13の上端に、円柱状のグリップエンド部21が回転可能に取り付けられている。かつ、このグリップエンド部21には、清掃用具20を吊下げて置いておくためのフックや紐等を通す挿入孔22が設けられ、様々な向きに設置されたフック等に対応して吊下げられるようになっている。
図８に示すように、巻付板25の上面側の前端縁と後端縁それぞれに、清掃シート３を取り付ける２個のシート装着具23が左右対称に付設され、巻付板25には合計４個のシート装着具23を有する。図７に於て、装着具23は、断面が丸みを帯びた長方形の筒部26と、その上部に付設された矩形薄肉状の天面部27と、から成っている。また、上記装着具23は樹脂製である。 In FIG. 13, a columnar grip end portion 21 is rotatably attached to the upper end of the gripping rod 13. In addition, the grip end portion 21 is provided with an insertion hole 22 through which a hook or string for hanging the cleaning tool 20 is hung and placed, and is suspended corresponding to hooks installed in various directions. It is supposed to be.
As shown in FIG. 8, two sheet mounting devices 23 for attaching the cleaning sheet 3 are attached symmetrically to the front end edge and the rear end edge on the upper surface side of the winding plate 25, respectively. There are four seat attachments 23. In FIG. 7, the mounting tool 23 includes a rectangular tube portion 26 having a rounded cross section, and a rectangular thin-walled top surface portion 27 attached to the upper portion thereof. The mounting tool 23 is made of resin.

図10に於て、矢印Ｆは、清掃シート３を清掃用具本体１に取り付け清掃する場合に、そのシート３に作用する頻度の多い引張力の向きを示している。上記装着具23の天面部27には、保持溝部２を備え、その保持溝部２は上記引張力の向きＦに直交する向きに全体として配設されている。さらに、保持溝部２は、２個の三角山形の掛止用スリット４，４と、２個の三角山形の押圧用スリット５，５と、短線状連結スリット６…と、枝状スリット12，12と、から成っている。 In FIG. 10, when the cleaning sheet 3 is attached to the cleaning tool main body 1 for cleaning, the arrow F indicates the direction of the frequent tensile force acting on the sheet 3. The top surface portion 27 of the mounting tool 23 includes a holding groove portion 2, and the holding groove portion 2 is disposed as a whole in a direction orthogonal to the direction F of the tensile force. Further, the holding groove portion 2 includes two triangular chevron-shaped latching slits 4, 4, two triangular chevron-shaped pressing slits 5, 5, a short connecting slit 6, and branch-shaped slits 12, 12. And consists of:

上記押圧用スリット５，５は所定間隔をもって並設され、押圧用スリット５の頂角部11，11は、上記引張力の向きＦに配置されている。上記掛止用スリット４，４は、２個の押圧用スリット５，５の両側に所定間隔をもって配設され、掛止用スリット４，４の頂角部10，10は引張力の向きＦと反対方向に向いて配置されている。さらに、並設された押圧用スリット５，５同士及び押圧用スリット５と掛止用スリット４を、上記短線状連結スリット６にて連結し、その短線状連結スリット６は、掛止用スリット４及び押圧用スリット５の上記三角山形の各斜辺中間部に付設されている。つまり、１つのシート装着具23に於ける全ての短線状連結スリット６は、同一直線状に形成されている。
さらに、上記保持溝部２の全体として両端側に、上記枝状スリット12が設けられ、すなわち、枝状スリット12は、上記短線状連結スリット６が連結した掛止用スリット４の斜辺とは別の斜辺に連結されている。枝状スリット12は、短線状連結スリット６と同一直線状に設けられた１個のスリットと、そのスリットから外方拡大状に延びる２個のスリットと、から成っている。 The pressing slits 5 and 5 are arranged in parallel with a predetermined interval, and the apex portions 11 and 11 of the pressing slit 5 are arranged in the direction F of the tensile force. The latching slits 4, 4 are arranged at predetermined intervals on both sides of the two pressing slits 5, 5, and the apex portions 10, 10 of the latching slits 4, 4 have a direction F of the tensile force. They are arranged in the opposite direction. Further, the pressing slits 5, 5 arranged side by side and the pressing slit 5 and the latching slit 4 are connected by the short-line connecting slit 6, and the short-line connecting slit 6 is the latching slit 4. In addition, the pressing slit 5 is provided at the middle part of each hypotenuse of the triangular mountain shape. That is, all the short-line connecting slits 6 in one sheet mounting tool 23 are formed in the same straight line.
Further, the branch slits 12 are provided on both ends of the holding groove 2 as a whole, that is, the branch slits 12 are different from the oblique sides of the latching slits 4 connected by the short-line connecting slits 6. Connected to the hypotenuse. The branch slit 12 is composed of one slit provided in the same straight line as the short-line connecting slit 6 and two slits extending outwardly from the slit.

また、上記掛止用スリット４は、三角山形の掛止片７を形成し、また、上記押圧用スリット５は、三角山形の押圧片８を形成している。掛止用スリットの開き角度θは35度以上58度以下に設定されている。開き角度θが35度未満となると、掛止片７の強度が維持できず、引張力の作用する清掃シート３を充分に掛止できない。また、開き角度θが58度よりも大きくなると、掛止片７が清掃シート３に差し込まれにくくなり、充分に掛止できなくなる。 The latching slit 4 forms a triangular mountain-shaped latching piece 7, and the pressing slit 5 forms a triangular mountain-shaped pressing piece 8. The opening angle θ of the latching slit is set to 35 degrees or more and 58 degrees or less. When the opening angle θ is less than 35 degrees, the strength of the retaining piece 7 cannot be maintained, and the cleaning sheet 3 on which the tensile force acts cannot be sufficiently retained. When the opening angle θ is greater than 58 degrees, the latch piece 7 is difficult to be inserted into the cleaning sheet 3 and cannot be sufficiently latched.

図10と図11に示すように、該押圧片８の裏面には突条の補強リブ９が設けられている。その補強リブ９の平面視した形状は、押圧片８の上記三角山形の両斜辺に沿って山形に形成されている。また、それ以外に、補強リブ９の平面視した形状は、上記引張力の向きＦに平行に配置された細棒状や、該細棒状と上記山形を組み合わせた略矢印状であってもよい。 As shown in FIG. 10 and FIG. 11, a reinforcing rib 9 is provided on the back surface of the pressing piece 8. The shape of the reinforcing rib 9 in plan view is formed in a mountain shape along both the oblique sides of the triangular mountain shape of the pressing piece 8. In addition, the shape of the reinforcing rib 9 in plan view may be a thin rod shape arranged in parallel with the direction F of the tensile force, or a substantially arrow shape in which the thin rod shape and the mountain shape are combined.

さらに、上記巻付板25の前後左右の側面と下面には、クッション部材24を有し、図９に示すように、そのクッション部材24の裏面には、複数本の波状の突部28が並列して一体状に設けられている。この複数本の波状の突部28は、清掃時に本体１をどの方向に動かしても、その動く方向に直交してゴミ・埃等を捕らえ取り残すことがなく、確実に清掃シート３にゴミ等を付着させるように、互いに密集して設けられている。また、この実施の形態では、上記複数本の突部28は、左右に並列して配置されているが、それ以外の方向に並列して設けられてもよい。また、クッション部材24の材質は、ゴム・軟質樹脂等である。 Further, cushion members 24 are provided on the front, rear, left and right side surfaces and the lower surface of the winding plate 25, and a plurality of wavy projections 28 are arranged in parallel on the back surface of the cushion member 24 as shown in FIG. And are provided integrally. The plurality of wavy projections 28 ensure that dust or the like can be removed from the cleaning sheet 3 without being trapped in any direction perpendicular to the direction of movement of the main body 1 in any direction during cleaning. They are closely packed together so that they adhere. Further, in this embodiment, the plurality of protrusions 28 are arranged in parallel in the left and right, but may be provided in parallel in other directions. The material of the cushion member 24 is rubber, soft resin, or the like.

上述した本発明である清掃用具の使用方法（作用）について説明する。
図６に於て、上記クッション部材24の裏面から上記巻付板25の上面へ、清掃シート３を巻き付け、そのシート３の上記保持溝部２の上方に位置する部分を、２本の指でシート装着具23内へ押し込む。この時、指の押圧でシート装着具23の掛止片７と押圧片８は、下方へ湾曲し、シート３はシート装着具23内に押し込まれる。そして、指をシート３から離すと、掛止片７と押圧片８は元の形状に戻り、掛止片７はシート３に差し込まれ、押圧片８はシート３を上記引張力の向きＦへ押圧し、押圧用スリット５の間に挾持する。この結果、シート３は保持溝部２に噛み込まれ保持される。 The use method (action | operation) of the cleaning tool which is this invention mentioned above is demonstrated.
In FIG. 6, the cleaning sheet 3 is wound from the back surface of the cushion member 24 to the upper surface of the winding plate 25, and the portion of the sheet 3 positioned above the holding groove portion 2 is seated with two fingers. Push into the fitting 23. At this time, the latching piece 7 and the pressing piece 8 of the seat mounting tool 23 are bent downward by the finger pressing, and the seat 3 is pushed into the seat mounting tool 23. When the finger is released from the sheet 3, the latching piece 7 and the pressing piece 8 return to the original shape, the latching piece 7 is inserted into the sheet 3, and the pressing piece 8 brings the sheet 3 into the direction F of the tensile force. Press and hold between the pressing slits 5. As a result, the sheet 3 is held in the holding groove 2.

次に、把持杆13を所望の長さに調整し、把持杆13を手で持って、清掃用具本体１を床上で前後に往復させ清掃する。この前後の往復運動によって、上記噛み込まれ保持されたシート３には、矢印Ｆの方向に引張力が作用し、そして、掛止片７の先端部は、引張力が作用したシート３に、さらに差し込まれることになる。なお、清掃する際は、上記本体１を前後に往復運動させるだけでなく、左右方向、また、それ以外の方向に往復運動させても自由である。
また、清掃シート３が汚れ廃棄する場合、または、別のシート３に交換する場合は、保持溝部２から外部へ出ているシート３の端を、指で摘んで引き抜き、本体１から取り外す。 Next, the gripping rod 13 is adjusted to a desired length, the gripping rod 13 is held by hand, and the cleaning tool body 1 is moved back and forth on the floor to clean it. By this back and forth reciprocating motion, a tensile force acts in the direction of arrow F on the bite 3 held and held, and the tip of the latching piece 7 is applied to the sheet 3 on which the tensile force is applied. It will be inserted further. When cleaning, not only reciprocating the main body 1 back and forth, but it is also possible to reciprocate in the left-right direction and other directions.
In addition, when the cleaning sheet 3 is discarded and replaced with another sheet 3, the edge of the sheet 3 that is exposed to the outside from the holding groove 2 is picked up by a finger and pulled out and removed from the main body 1.

以上のように、本発明である清掃用具は、清掃用具本体１の上面側に保持溝部２を有し、上記清掃用具本体１の下面から上面へと巻き付けられた清掃シート３を上記保持溝部２で着脱自在に保持する清掃用具20に於て、上記保持溝部２は、上記清掃シート３に作用する引張力の向きＦに直交する方向に全体として配設され、かつ、該保持溝部２には、２個の三角山形の押圧用スリット５，５を所定間隔をもって引張力の向きＦにその頂角部11が向くように並設すると共に、２個の該押圧用スリット５，５の両側に、それぞれ三角山形の掛止用スリット４を所定間隔をもって上記引張力の向きＦと反対方向にその頂角部10が向くように配設し、かつ、掛止用スリット４、押圧用スリット５、押圧用スリット５及び掛止用スリット４の三角山形の各斜辺中間部を、短線状連結スリット６にて順次連結し、保持溝部２は、全体としての両端側に、外方拡大状の枝状スリット12をそれぞれ有するので、２本以上の指でシート装着具23内へ清掃シート３を押し込みやすく、シート装着具23はそのシート３を幅広で均等に挾持でき、清掃時にシート３に引張力が作用してもシート装着具23から外れることがなくなる。
さらに、掛止片７はシート３に差し込まれ、押圧片８はシート３を押圧し押圧用スリット５の間に挾持するので、シート３を確実に保持できる。
さらに、保持溝部２は短線状連結スリット６を軸としてほぼ対称に開口できるので、指でシート３をシート装着具23に充分に押し込むことができ、装着具23の保持力を向上させ、かつ、シート３の取付け作業も容易となる。
また、枝状スリット12を有することにより、指でシート装着具23内へシート３を押し込む際、押圧片８は下方へ湾曲しやすくなり、シート３を押圧片８の下方に充分に押し込むことができ、押圧片８による挾持力が充分に発揮される。 As described above, the cleaning tool according to the present invention has the holding groove portion 2 on the upper surface side of the cleaning tool body 1, and the cleaning sheet 3 wound from the lower surface to the upper surface of the cleaning tool body 1 is placed on the holding groove portion 2. In the cleaning tool 20 that is detachably held in the holding groove portion 2, the holding groove portion 2 is disposed as a whole in a direction perpendicular to the direction F of the tensile force acting on the cleaning sheet 3. Two triangular chevron-shaped pressing slits 5, 5 are arranged side by side with a predetermined interval so that the apex portion 11 faces in the direction F of the tensile force, and on both sides of the two pressing slits 5, 5. , Each of the triangular mountain-shaped latching slits 4 are arranged with a predetermined interval so that the apex portion 10 faces in the direction opposite to the direction F of the tensile force , and the latching slit 4, the pressing slit 5, Each of the triangular mountain shape of the pressing slit 5 and the latching slit 4 The sides intermediate part, sequentially connected by a short wire-like connecting slit 6, the holding groove 2, at both ends as a whole, since it has an outer expansion-shaped branched slits 12, respectively, seat mounted at least two fingers The cleaning sheet 3 can be easily pushed into the tool 23, and the sheet mounting tool 23 can hold the sheet 3 wide and evenly, and even if a tensile force is applied to the sheet 3 during cleaning, the sheet mounting tool 23 does not come off the sheet mounting tool 23.
Furthermore, since the latching piece 7 is inserted into the sheet 3 and the pressing piece 8 presses the sheet 3 and holds it between the pressing slits 5, the sheet 3 can be reliably held.
Further, since the holding groove portion 2 can be opened almost symmetrically with the short-line connecting slit 6 as an axis, the sheet 3 can be sufficiently pushed into the sheet mounting tool 23 with a finger, the holding power of the mounting tool 23 is improved, and The attachment work of the seat 3 is also facilitated.
Further, by having the branch slit 12, when the sheet 3 is pushed into the sheet mounting tool 23 with a finger, the pressing piece 8 is easily bent downward, and the sheet 3 can be sufficiently pushed below the pressing piece 8. The holding force by the pressing piece 8 is sufficiently exhibited.

また、清掃用具本体１の上面側に保持溝部２を有し、上記清掃用具本体１の下面から上面へと巻き付けられた清掃シート３を上記保持溝部２で着脱自在に保持する清掃用具20に於て、上記保持溝部２は、上記清掃シート３に作用する引張力の向きＦに直交する方向に全体として配設され、かつ、該保持溝部２には、２個の三角山形の押圧用スリット５，５を所定間隔をもって引張力の向きＦにその頂角部11が向くように並設すると共に、２個の該押圧用スリット５，５の両側に、それぞれ三角山形の掛止用スリット４を所定間隔をもって上記引張力の向きＦと反対方向にその頂角部10が向くように配設し、かつ、上記掛止用スリット４の開き角度θは、35度以上58度以下に設定され、さらに、上記掛止用スリット４、押圧用スリット５、押圧用スリット５及び掛止用スリット４の上記三角山形の各斜辺中間部を、短線状連結スリット６にて順次連結し、保持溝部２は、全体としての両端側に、外方拡大状の枝状スリット12をそれぞれ有するので、２本以上の指でシート装着具23内へ清掃シート３を押し込みやすく、シート装着具23はそのシート３を幅広で均等に挾持でき、清掃時にシート３に引張力が作用してもシート装着具23から外れることがなくなる。
また、掛止片７はシート３に差し込まれ、押圧片８はシート３を上方へ押圧し押圧用スリット５の間に挾持するので、シート３を確実に保持できる。
さらに、保持溝部２は短線状連結スリット６を軸としてほぼ対称に開口できるので、指でシート３をシート装着具23に充分に押し込むことができ、装着具23の保持力を向上させ、かつ、シート３の取付け作業も容易となる。

The sheet mounting tool 23 can hold the sheet 3 wide and evenly, and the tensile force is applied to the sheet 3 during cleaning. Even if it acts, it will not come off the seat mounting tool 23.
Further, the latching piece 7 is inserted into the sheet 3 and the pressing piece 8 presses the sheet 3 upward and is held between the pressing slits 5, so that the sheet 3 can be reliably held.
Further, since the holding groove portion 2 can be opened almost symmetrically with the short-line connecting slit 6 as an axis, the sheet 3 can be sufficiently pushed into the sheet mounting tool 23 with a finger, the holding power of the mounting tool 23 is improved, and The attachment work of the seat 3 is also facilitated.
Further, by having the branch slit 12, when the sheet 3 is pushed into the sheet mounting tool 23 with a finger, the pressing piece 8 is easily bent downward, and the sheet 3 can be sufficiently pushed below the pressing piece 8. The holding force by the pressing piece 8 is sufficiently exhibited.

また、上記押圧用スリット５は三角山状の押圧片８を形成し、該押圧片８の裏面に補強リブ９を設けたので、押圧片８の引張力の向きＦへの押圧力を一層強固なものとできシート装着具23の保持力が向上される。
また、清掃時に清掃用具本体１を左右方向に往復させた場合でも、上記補強リブ９によって清掃シート３は掛止され、シート３が左右方向に撓むのを防止する。従って、シート装着具23は、均等かつ確実にシート３を保持できる。 Also, the pressing slit 5 forms a pressing piece 8 of Mikadoyama like, is provided with the reinforcing ribs 9 on the back surface of the pressing flaked 8, further a pressing force to the direction F of the tensile force of the pressing piece 8 It can be made strong and the holding power of the seat mounting device 23 is improved.
Further, even when the cleaning tool main body 1 is reciprocated in the left-right direction during cleaning, the cleaning sheet 3 is hooked by the reinforcing rib 9 to prevent the sheet 3 from being bent in the left-right direction. Therefore, the seat mounting tool 23 can hold the seat 3 evenly and reliably.
