しかしながら、かかる清掃用具を用いて部屋の角を清掃しようとすると、ヘッド部と部屋の角との間にどうしても隙間が生じてしまう。そのため、部屋の角においては、床面の埃を捕集しきれない等、清掃が不充分になりがちである。このように、従来の清掃用具には、部屋の角において床を清掃しにくいという問題があった。 However, when such a cleaning tool is used to clean a corner of a room, a gap is inevitably generated between the head portion and the corner of the room. For this reason, cleaning tends to be insufficient at the corners of the room, for example, because dust on the floor cannot be collected. Thus, the conventional cleaning tool has a problem that it is difficult to clean the floor at the corner of the room.

本発明は、上記課題に鑑みてなされたものであり、部屋の角においても床を清掃しやすい清掃用具を提供することを目的とする。 This invention is made | formed in view of the said subject, and it aims at providing the cleaning tool which is easy to clean a floor also in the corner of a room.

本発明による清掃用具は、清掃シートを装着可能であり、第１乃至第４の側面を有する矩形板状のヘッド部と、上記ヘッド部に連結された柄と、上記ヘッド部の四隅のうち、上記第１の側面と上記第２の側面とが交わる第１の隅に設けられた第１の切込部と、を備え、上記第１の切込部は、上記第１の側面に形成された複数の第１の横切込線と、上記第２の側面に形成された複数の第２の横切込線と、上記第１及び第２の側面の間の辺に沿って形成された第１の縦切込線とを含み、上記各第１の横切込線及び上記各第２の横切込線の一端は、上記第１の縦切込線上に位置することを特徴とする。 The cleaning tool according to the present invention can be fitted with a cleaning sheet and has a rectangular plate-shaped head portion having first to fourth side surfaces, a handle connected to the head portion, and four corners of the head portion. A first cut portion provided at a first corner where the first side surface and the second side surface intersect, and the first cut portion is formed on the first side surface. A plurality of first horizontal cut lines, a plurality of second horizontal cut lines formed on the second side surface, and a side between the first and second side surfaces. One end of each of the first horizontal cut lines and each of the second horizontal cut lines is located on the first vertical cut line. .

この清掃用具においては、ヘッド部の隅（第１の隅）に、第１及び第２の横切込線並びに第１の縦切込線を含む第１の切込部が設けられている。第１の横切込線は第１の側面に複数形成されており、各第１の横切込線の一端は、第１及び第２の側面の間の辺に沿って形成された第１の縦切込線上に位置する。同様に、第２の横切込線は第２の側面に複数形成されており、各第２の横切込線の一端も、第１の縦切込線上に位置する。これにより、第１の側面において複数の第１の横切込線で挟まれた部分は、先端が自由端となる。同様に、第２の側面において複数の第２の横切込線で挟まれた部分も、先端が自由端となる。このため、ヘッド部の第１の隅を部屋の角に押し付けることにより、上記部分を変形させて、当該角に第１の隅を密着させることができる。これにより、部屋の角においても、床の清掃を充分に行うことができる。 In this cleaning tool, a first cut portion including first and second horizontal cut lines and a first vertical cut line is provided at a corner (first corner) of the head portion. A plurality of first horizontal cut lines are formed on the first side surface, and one end of each first horizontal cut line is formed along the side between the first and second side surfaces. Located on the vertical score line. Similarly, a plurality of second horizontal cut lines are formed on the second side surface, and one end of each second horizontal cut line is located on the first vertical cut line. Thereby, the front-end | tip becomes a free end in the part pinched | interposed by the some 1st horizontal cut line in the 1st side surface. Similarly, the tip of the portion sandwiched between the plurality of second horizontal cut lines on the second side surface is a free end. For this reason, by pressing the first corner of the head portion against the corner of the room, the portion can be deformed and the first corner can be brought into close contact with the corner. Thereby, the floor can be sufficiently cleaned even at the corner of the room.

本発明によれば、部屋の角においても床を清掃しやすい清掃用具が実現される。 ADVANTAGE OF THE INVENTION According to this invention, the cleaning tool which is easy to clean a floor also in the corner of a room is implement | achieved.

清掃用具１の効果を説明する。清掃用具１においては、ヘッド部１０の隅１２に、切込線３２，３４，３６を含む切込部３０が設けられている。切込線３２は側面１０ａに複数形成されており、各切込線３２の一端は、側面１０ａと側面１０ｂとの間の辺に沿って形成された切込線３６上に位置する。同様に、切込線３４は側面１０ｂに複数形成されており、各切込線３４の一端も、切込線３６上に位置する。これにより、側面１０ａにおいて複数の切込線３２で挟まれた舌片状の部分３３は、先端（切込線３６上に位置する端）が自由端となる。すなわち、当該部分３３は、その先端において隣の側面（側面１０ｂ）に固定されておらず、自由に動くことができる。 The effect of the cleaning tool 1 will be described. In the cleaning tool 1, a cut portion 30 including cut lines 32, 34, and 36 is provided at the corner 12 of the head portion 10. A plurality of the cut lines 32 are formed on the side surface 10a, and one end of each cut line 32 is located on a cut line 36 formed along the side between the side surface 10a and the side surface 10b. Similarly, a plurality of cut lines 34 are formed on the side surface 10 b, and one end of each cut line 34 is located on the cut line 36. Thereby, as for the tongue-like part 33 pinched | interposed by the some cutting line 32 in the side surface 10a, the front-end | tip (end located on the cutting line 36) becomes a free end. That is, the portion 33 is not fixed to the adjacent side surface (side surface 10b) at the tip, and can move freely.

同様に、側面１０ｂにおいて複数の切込線３４で挟まれた舌片状の部分３５も、先端が自由端となる。このため、ヘッド部１０の隅１２を部屋の角（床面と２つの壁面とが集まる部分）に押し付けることにより、上記部分３３，３５を変形させて、当該角に隅１２を密着させることができる。これにより、部屋の角においても、床の清掃を充分に行うことができる。したがって、部屋の角においても床を清掃しやすい清掃用具１が実現されている。 Similarly, the tongue-like portion 35 sandwiched between the plurality of cut lines 34 on the side surface 10b has a free end. Therefore, by pressing the corner 12 of the head portion 10 against the corner of the room (the portion where the floor and the two wall surfaces gather), the portions 33 and 35 can be deformed, and the corner 12 can be brought into close contact with the corner. it can. Thereby, the floor can be sufficiently cleaned even at the corner of the room. Therefore, the cleaning tool 1 that easily cleans the floor at the corner of the room is realized.

複数の切込線３２は、互いに平行である。また、複数の切込線３４も、互いに平行である。このため、舌片状の各部分３３，３５は、幅が一定になり、強度的に安定する。これにより、当該部分３３，３５を大きく変形させることが可能となるため、部屋の角に対して隅１２を密着させやすくなる。 The plurality of score lines 32 are parallel to each other. The plurality of score lines 34 are also parallel to each other. For this reason, each of the tongue-like portions 33 and 35 has a constant width and is stable in strength. Accordingly, the portions 33 and 35 can be largely deformed, and the corner 12 can be easily adhered to the corner of the room.

複数の切込線３２は、ヘッド部１０の厚み方向について、側面１０ａの略全体にわたって形成されている。また、複数の切込線３４も、上記方向について、側面１０ｂの略全体にわたって形成されている。これにより、ヘッド部１０の隅１２の略全体を変形させることが可能となるため、部屋の角に対する隅１２の密着度を向上させることができる。 The plurality of cut lines 32 are formed over substantially the entire side surface 10 a in the thickness direction of the head portion 10. The plurality of score lines 34 are also formed over substantially the entire side surface 10b in the above direction. As a result, almost the entire corner 12 of the head unit 10 can be deformed, so that the degree of contact of the corner 12 with the corner of the room can be improved.

複数の切込線３２の１つは、ヘッド部１０の底面と側面１０ａとの間の辺に沿って形成されている。また、複数の切込線３４の１つも、ヘッド部１０の底面と側面１０ｂとの間の辺に沿って形成されている。これにより、ヘッド部１０の隅１２を部屋の角に押し付ける際、床面の極近傍において隅１２を変形させることが可能となる。このことも、部屋の角に対する隅１２の密着度の向上に資する。 One of the plurality of cut lines 32 is formed along a side between the bottom surface of the head unit 10 and the side surface 10a. One of the plurality of cut lines 34 is also formed along the side between the bottom surface of the head portion 10 and the side surface 10b. Accordingly, when the corner 12 of the head unit 10 is pressed against the corner of the room, the corner 12 can be deformed in the vicinity of the floor surface. This also contributes to improvement in the degree of adhesion of the corner 12 with respect to the corner of the room.

隣り合う２本の切込線３２どうしの間隔ｄ１（図２参照）が大きすぎると、舌片状の部分３３の変形量が不足し、当該部分３３を部屋の角に密着させにくくなる。かかる観点から、間隔ｄ１は、３ｍｍ以下であることが好ましい。他方、間隔ｄ１が小さすぎると、上記部分３３の強度が不足する。かかる観点から、間隔ｄ１は、１ｍｍ以上であることが好ましい。隣り合う２本の切込線３４どうしの間隔についても、同様の理由から、１ｍｍ以上３ｍｍ以下であることが好ましい。 If the distance d1 (see FIG. 2) between two adjacent cut lines 32 is too large, the amount of deformation of the tongue-like portion 33 will be insufficient, and it will be difficult for the portion 33 to adhere to the corner of the room. From such a viewpoint, the distance d1 is preferably 3 mm or less. On the other hand, if the distance d1 is too small, the strength of the portion 33 is insufficient. From this viewpoint, the distance d1 is preferably 1 mm or more. The interval between two adjacent cut lines 34 is also preferably 1 mm or more and 3 mm or less for the same reason.

各切込線３２の長さｄ２（図２参照）が小さすぎると、舌片状の部分３３の変形量が不足し、当該部分３３を部屋の角に密着させにくくなる。かかる観点から、長さｄ２は、１０ｍｍ以上であることが好ましい。他方、長さｄ２が大きすぎると、ヘッド部１０全体の機械的強度が低下してしまう。かかる観点から、長さｄ２は、３０ｍｍ以下であることが好ましい。各切込線３４の長さについても、同様の理由から、１０ｍｍ以上３０ｍｍ以下であることが好ましい。 If the length d2 (see FIG. 2) of each score line 32 is too small, the amount of deformation of the tongue-like portion 33 is insufficient, and it becomes difficult to make the portion 33 adhere to the corner of the room. From such a viewpoint, the length d2 is preferably 10 mm or more. On the other hand, if the length d2 is too large, the mechanical strength of the entire head unit 10 is lowered. From such a viewpoint, the length d2 is preferably 30 mm or less. The length of each cut line 34 is preferably 10 mm or more and 30 mm or less for the same reason.

A plurality of score lines 42 are formed on the side surface 10b, and one end of each score line 42 is located on a score line 46 formed along the side between the side surface 10b and the side surface 10c. Similarly, a plurality of cut lines 44 are formed on the side surface 10 c, and one end of each cut line 44 is located on the cut line 46. Thereby, as for the tongue-like part 43 pinched | interposed by the some cutting line 42 in the side surface 10b, the front-end | tip (end located on the cutting line 46) becomes a free end. Similarly, the tip of the tongue-like portion 45 sandwiched between the plurality of cut lines 44 on the side surface 10c is a free end. For this reason, by pressing the corner 14 of the head portion 10 against the corner of the room, the portions 43 and 45 can be deformed and the corner 14 can be brought into close contact with the corner. Thereby, the floor can be sufficiently cleaned even at the corner of the room.

複数の切込線４２は、互いに平行である。また、複数の切込線４４も、互いに平行である。このため、舌片状の各部分４３，４５は、幅が一定になり、強度的に安定する。これにより、当該部分４３，４５を大きく変形させることが可能となるため、部屋の角に対して隅１４を密着させやすくなる。 The plurality of score lines 42 are parallel to each other. The plurality of score lines 44 are also parallel to each other. Therefore, each of the tongue-like portions 43 and 45 has a constant width and is stable in strength. Accordingly, the portions 43 and 45 can be greatly deformed, so that the corner 14 is easily brought into close contact with the corner of the room.

複数の切込線４２は、ヘッド部１０の厚み方向について、側面１０ｂの略全体にわたって形成されている。また、複数の切込線４４も、上記方向について、側面１０ｃの略全体にわたって形成されている。これにより、ヘッド部１０の隅１４の略全体を変形させることが可能となるため、部屋の角に対する隅１４の密着度を向上させることができる。 The plurality of cut lines 42 are formed over substantially the entire side surface 10 b in the thickness direction of the head portion 10. The plurality of cut lines 44 are also formed over substantially the entire side surface 10c in the above direction. As a result, almost the entire corner 14 of the head portion 10 can be deformed, so that the degree of contact of the corner 14 with the corner of the room can be improved.

複数の切込線４２の１つは、ヘッド部１０の底面と側面１０ｂとの間の辺に沿って形成されている。また、複数の切込線４４の１つも、ヘッド部１０の底面と側面１０ｃとの間の辺に沿って形成されている。これにより、ヘッド部１０の隅１４を部屋の角に押し付ける際、床面の極近傍において隅１４を変形させることが可能となる。このことも、部屋の角に対する隅１４の密着度の向上に資する。 One of the plurality of cut lines 42 is formed along a side between the bottom surface of the head unit 10 and the side surface 10b. One of the plurality of cut lines 44 is also formed along the side between the bottom surface of the head portion 10 and the side surface 10c. Accordingly, when the corner 14 of the head unit 10 is pressed against the corner of the room, the corner 14 can be deformed in the vicinity of the floor surface. This also contributes to improvement in the degree of adhesion of the corner 14 with respect to the corner of the room.

隣り合う２本の切込線４２どうしの間隔が大きすぎると、舌片状の部分４３の変形量が不足し、当該部分４３を部屋の角に密着させにくくなる。かかる観点から、上記間隔は、３ｍｍ以下であることが好ましい。他方、上記間隔が小さすぎると、上記部分４３の強度が不足する。かかる観点から、上記間隔は、１ｍｍ以上であることが好ましい。隣り合う２本の切込線４４どうしの間隔についても、同様の理由から、１ｍｍ以上３ｍｍ以下であることが好ましい。 If the distance between two adjacent cut lines 42 is too large, the amount of deformation of the tongue-like portion 43 will be insufficient, and it will be difficult to bring the portion 43 into close contact with the corner of the room. From this viewpoint, the interval is preferably 3 mm or less. On the other hand, if the interval is too small, the strength of the portion 43 is insufficient. From this viewpoint, the interval is preferably 1 mm or more. The interval between two adjacent cut lines 44 is preferably 1 mm or more and 3 mm or less for the same reason.

各切込線４２の長さが小さすぎると、舌片状の部分４３の変形量が不足し、当該部分４３を部屋の角に密着させにくくなる。かかる観点から、上記長さは、１０ｍｍ以上であることが好ましい。他方、上記長さが大きすぎると、ヘッド部１０全体の機械的強度が低下してしまう。かかる観点から、上記長さは、３０ｍｍ以下であることが好ましい。各切込線４４の長さについても、同様の理由から、１０ｍｍ以上３０ｍｍ以下であることが好ましい。 If the length of each cutting line 42 is too small, the deformation amount of the tongue-like portion 43 is insufficient, and it becomes difficult to make the portion 43 adhere to the corner of the room.

One of the plurality of cut lines 54 is also formed along the side between the bottom surface of the head portion 10 and the side surface 10d. Accordingly, when the corner 16 of the head unit 10 is pressed against the corner of the room, the corner 16 can be deformed in the very vicinity of the floor surface. This also contributes to an improvement in the degree of adhesion of the corner 16 with respect to the corner of the room.

隣り合う２本の切込線５２どうしの間隔が大きすぎると、舌片状の部分５３の変形量が不足し、当該部分５３を部屋の角に密着させにくくなる。かかる観点から、上記間隔は、３ｍｍ以下であることが好ましい。他方、上記間隔が小さすぎると、上記部分５３の強度が不足する。かかる観点から、上記間隔は、１ｍｍ以上であることが好ましい。隣り合う２本の切込線５４どうしの間隔についても、同様の理由から、１ｍｍ以上３ｍｍ以下であることが好ましい。 If the distance between two adjacent cut lines 52 is too large, the amount of deformation of the tongue-like portion 53 will be insufficient, making it difficult to bring the portion 53 into close contact with the corner of the room. From this viewpoint, the interval is preferably 3 mm or less. On the other hand, if the interval is too small, the strength of the portion 53 is insufficient. From this viewpoint, the interval is preferably 1 mm or more. The interval between two adjacent cut lines 54 is also preferably 1 mm or more and 3 mm or less for the same reason.

各切込線５２の長さが小さすぎると、舌片状の部分５３の変形量が不足し、当該部分５３を部屋の角に密着させにくくなる。かかる観点から、上記長さは、１０ｍｍ以上であることが好ましい。他方、上記長さが大きすぎると、ヘッド部１０全体の機械的強度が低下してしまう。かかる観点から、上記長さは、３０ｍｍ以下であることが好ましい。各切込線５４の長さについても、同様の理由から、１０ｍｍ以上３０ｍｍ以下であることが好ましい。 If the length of each cutting line 52 is too small, the deformation amount of the tongue-like portion 53 is insufficient, and it becomes difficult to make the portion 53 adhere to the corner of the room. From this viewpoint, the length is preferably 10 mm or more. On the other hand, if the length is too large, the mechanical strength of the entire head unit 10 is lowered. From this viewpoint, the length is preferably 30 mm or less. The length of each cut line 54 is also preferably 10 mm or more and 30 mm or less for the same reason.

ヘッド部１０の隅１８に、切込線６２，６４，６６を含む切込部６０が設けられている。切込線６２は側面１０ｄに複数形成されており、各切込線６２の一端は、側面１０ｄと側面１０ａとの間の辺に沿って形成された切込線６６上に位置する。同様に、切込線６４は側面１０ａに複数形成されており、各切込線６４の一端も、切込線６６上に位置する。これにより、側面１０ｄにおいて複数の切込線６２で挟まれた舌片状の部分６３は、先端（切込線６６上に位置する端）が自由端となる。同様に、側面１０ａにおいて複数の切込線６４で挟まれた舌片状の部分６５も、先端が自由端となる。このため、ヘッド部１０の隅１８を部屋の角に押し付けることにより、上記部分６３，６５を変形させて、当該角に隅１８を密着させることができる。これにより、部屋の角においても、床の清掃を充分に行うことができる。 A cut portion 60 including cut lines 62, 64, 66 is provided at the corner 18 of the head portion 10. A plurality of cut lines 62 are formed on the side surface 10d, and one end of each cut line 62 is located on a cut line 66 formed along the side between the side surface 10d and the side surface 10a. Similarly, a plurality of cut lines 64 are formed on the side surface 10 a, and one end of each cut line 64 is located on the cut line 66. Thereby, as for the tongue-like part 63 pinched | interposed by the some cutting line 62 in the side surface 10d, the front-end | tip (end located on the cutting line 66) becomes a free end. Similarly, the tongue-like portion 65 sandwiched between the plurality of cut lines 64 on the side surface 10a has a free end. For this reason, by pressing the corner 18 of the head portion 10 against the corner of the room, the portions 63 and 65 can be deformed, and the corner 18 can be brought into close contact with the corner. Thereby, the floor can be sufficiently cleaned even at the corner of the room.

複数の切込線６２は、互いに平行である。また、複数の切込線６４も、互いに平行である。このため、舌片状の各部分６３，６５は、幅が一定になり、強度的に安定する。これにより、当該部分６３，６５を大きく変形させることが可能となるため、部屋の角に対して隅１８を密着させやすくなる。 The plurality of score lines 62 are parallel to each other. The plurality of score lines 64 are also parallel to each other. For this reason, each of the tongue-like portions 63 and 65 has a constant width and is stable in strength. Thus, the portions 63 and 65 can be greatly deformed, and the corner 18 can be easily adhered to the corner of the room.

複数の切込線６２は、ヘッド部１０の厚み方向について、側面１０ｄの略全体にわたって形成されている。また、複数の切込線６４も、上記方向について、側面１０ａの略全体にわたって形成されている。これにより、ヘッド部１０の隅１８の略全体を変形させることが可能となるため、部屋の角に対する隅１８の密着度を向上させることができる。 The plurality of cut lines 62 are formed over substantially the entire side surface 10 d in the thickness direction of the head portion 10. The plurality of score lines 64 are also formed over substantially the entire side surface 10a in the above direction. As a result, almost the entire corner 18 of the head portion 10 can be deformed, so that the degree of adhesion of the corner 18 with respect to the corner of the room can be improved.

複数の切込線６２の１つは、ヘッド部１０の底面と側面１０ｄとの間の辺に沿って形成されている。また、複数の切込線６４の１つも、ヘッド部１０の底面と側面１０ａとの間の辺に沿って形成されている。これにより、ヘッド部１０の隅１８を部屋の角に押し付ける際、床面の極近傍において隅１８を変形させることが可能となる。このことも、部屋の角に対する隅１８の密着度の向上に資する。 One of the plurality of cut lines 62 is formed along a side between the bottom surface of the head unit 10 and the side surface 10d. One of the plurality of cut lines 64 is also formed along the side between the bottom surface of the head unit 10 and the side surface 10a. Accordingly, when the corner 18 of the head unit 10 is pressed against the corner of the room, the corner 18 can be deformed in the very vicinity of the floor surface. This also contributes to improvement in the degree of adhesion of the corner 18 with respect to the corner of the room.

隣り合う２本の切込線６２どうしの間隔が大きすぎると、舌片状の部分６３の変形量が不足し、当該部分６３を部屋の角に密着させにくくなる。かかる観点から、上記間隔は、３ｍｍ以下であることが好ましい。他方、上記間隔が小さすぎると、上記部分６３の強度が不足する。かかる観点から、上記間隔は、１ｍｍ以上であることが好ましい。隣り合う２本の切込線６４どうしの間隔についても、同様の理由から、１ｍｍ以上３ｍｍ以下であることが好ましい。 If the interval between two adjacent cut lines 62 is too large, the amount of deformation of the tongue-like portion 63 will be insufficient, making it difficult to bring the portion 63 into close contact with the corner of the room. From this viewpoint, the interval is preferably 3 mm or less. On the other hand, if the interval is too small, the strength of the portion 63 is insufficient. From this viewpoint, the interval is preferably 1 mm or more. The interval between two adjacent cut lines 64 is also preferably 1 mm or more and 3 mm or less for the same reason.

各切込線６２の長さが小さすぎると、舌片状の部分６３の変形量が不足し、当該部分６３を部屋の角に密着させにくくなる。かかる観点から、上記長さは、１０ｍｍ以上であることが好ましい。他方、上記長さが大きすぎると、ヘッド部１０全体の機械的強度が低下してしまう。かかる観点から、上記長さは、３０ｍｍ以下であることが好ましい。各切込線６４の長さについても、同様の理由から、１０ｍｍ以上３０ｍｍ以下であることが好ましい。 If the length of each cut line 62 is too small, the amount of deformation of the tongue-like portion 63 is insufficient, and it becomes difficult for the portion 63 to adhere to the corner of the room. From this viewpoint, the length is preferably 10 mm or more. On the other hand, if the length is too large, the mechanical strength of the entire head unit 10 is lowered. From this viewpoint, the length is preferably 30 mm or less. The length of each cut line 64 is also preferably 10 mm or more and 30 mm or less for the same reason.
