Description

[Technical field]

[0001] The present invention relates to a cleaning member and a cleaning tool. [Background technology]

[0002] As a conventional technique, for example, there is a cleaning tool body described in Patent Document 1. This cleaning tool body is equipped with a substantially rectangular, flat-plate-shaped holding part that can arrange the cleaning cloth by rolling it up vertically along its outer surface and that is gradually thinner toward the tip, and a rod-shaped grip part that is directly connected to the base end of the holding part. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4438783 Summary of the Invention [Problem to be solved by the invention]

[0004] When cleaning using the cleaning tool body, the cleaning cloth is attached to the holding part and then applied to the surface to be cleaned. At this time, it is necessary to bend the holding part in order to capture dirt over the entire surface. However, since the holding part is a roughly rectangular flat plate, it is difficult to bend, and if it is forcibly bent, there is a risk that the holding part will break under the load. Furthermore, if the holding part is stored in a bent state, it may become deformed and not return to its original shape.

[0005] Therefore, an object of the present invention is to provide a cleaning member and cleaning tool that are easily deformed but not easily broken, and that can return to their original shape even if deformed. [Means for solving the problem]

[0006] The present invention is a cleaning member to which a cleaning sheet is attached which, when in use, adheres dust for cleaning, and which forms a surface including a width direction and a length direction intersecting the width direction, wherein a plurality of inclined line portions extending in a direction inclined relative to the width direction intersect with a plurality of intersecting line portions extending in a direction intersecting the inclined line portions, thereby providing a constituent surface portion surrounded by a plurality of intersecting portions, and which is capable of deforming in the thickness direction when in contact with the surface to be cleaned from a thickness direction perpendicular to the surface, and is made of a material that has the ability to restore the original shape from the deformed shape.

[0007] According to the above configuration, for example, when the cleaning member with the cleaning sheet attached thereto is abutted against the surface to be cleaned from the thickness direction and deformed in the thickness direction in order to adhere the dust to the cleaning sheet attached to the cleaning member, the deformation force is distributed within the cleaning member by the constituent surface portion, making the cleaning member easier to deform but less likely to break, and further, even if the cleaning member is stored in a deformed shape, the restoring force can return the cleaning member to its original shape.

[0008] In the present invention, at least one of the inclined line portion and the intersecting line portion may be curved.

[0009] According to this configuration, it is possible to provide many variations in the shape pattern of the component surface portion.

[0010] In the present invention, the plurality of inclined line portions may be arranged substantially parallel to each other, and the plurality of intersecting line portions may be arranged substantially parallel to each other.

[0011] According to this configuration, the distance between the inclined line portions and the distance between the intersecting line portions can be constant regardless of the position.

[0012] In the present invention, the end portions in the width direction may be discontinuous in the length direction.

[0013] According to the above configuration, for example, when a force in the thickness direction is applied to a part of the widthwise end, the force in the thickness direction is not transmitted to the entire widthwise end, thereby preventing the entire cleaning member from twisting.

[0014] In addition, in the present invention, the component surface portion may be a quadrilateral having adjacent sides of the same length, and may have a first corner portion located on one diagonal of the quadrilateral shape and a second corner portion located on the other diagonal, and the angle of the first corner portion may be greater than the angle of the second corner portion.

[0015] According to the above configuration, when the cleaning member to which the cleaning sheet is attached is deformed in a state in which it is in contact with the contact surface, the cleaning member can be deformed at various angles.

[0016] In the present invention, the angle of the second corner portion may be less than 90 degrees.

[0017] According to this configuration, the cleaning member is less likely to crack when deformed in the thickness direction.

[0018] In the present invention, at least one of the first corner and the second corner may be rounded.

[0019] According to the above configuration, when the cleaning member is deformed, stress is prevented from concentrating on the first corner portion or the second corner portion, and the cleaning member is prevented from cracking at the first corner portion or the second corner portion.

[0020] In addition, in the present invention, the component surface portion may be rectangular and have a first corner portion located on one diagonal of the rectangular shape and a second corner portion located on the other diagonal, and a circular hole portion may be formed in at least the second corner portion.

[0021] According to this configuration, it is possible to increase the durability of the component surface portion against a deformation force when the cleaning member is deformed in the thickness direction.

[0022] In the present invention, the thickness may be in the range of 0.5 to 5.0 mm.

[0023] According to this configuration, the cleaning member can be flexibly deformed.

[0024] In the present invention, the material may include a plastic or an elastomer.

[0025] According to this configuration, even if the cleaning member is stored in a deformed shape for a long period of time, the cleaning member easily returns to its original shape.

[0026] In the present invention, the material may be at least one of polyethylene terephthalate resin, polycarbonate ABS resin, polypropylene resin, polyvinyl chloride resin and acrylic resin, or a combination of these.

[0027] According to this configuration, even if the cleaning member is stored in a deformed shape for a longer period of time, the cleaning member is likely to return to its original shape.

[0028] In the present invention, the thickness may be tapered from one side to the other in the longitudinal direction.

[0029] According to this configuration, the deformation strength of the cleaning member can be changed between one side and the other side in the length direction.

[0030] In the present invention, the length in the width direction may be shortened from one side in the length direction to the other side.

[0031] According to this configuration, the contact area of ​​the cleaning member with respect to the surface to be cleaned can be changed between one side and the other side in the longitudinal direction.

[0032] In addition, in the present invention, the component surface portions may be arranged in a plurality of portions in the longitudinal direction, and the component surface portions arranged on one side in the longitudinal direction may be larger than the component surface portions arranged on the other side in the longitudinal direction.

[0033] According to this configuration, for example, the base end side of the cleaning member in the length direction can be curved more easily than the tip end side of the cleaning member in the length direction.

[0034] The present invention also provides a cleaning tool comprising the above-mentioned cleaning member and a cleaning handle member detachably attached to the cleaning member. Effect of the Invention

[0035] As described above, according to the present invention, the deformation force is distributed within the cleaning member by the constituent surface portion, making the cleaning member easier to deform but less likely to break, and the restoring force allows the cleaning member to return to its original shape from a deformed shape.

[0037] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0038] 1, for ease of explanation, in the following explanation, the direction indicating the width of the cleaning tool 1 is referred to as the "first direction X," and the direction perpendicular to the first direction X that extends from the upper end 10 to the lower end 11 of the cleaning tool 1 is referred to as the "second direction Y." In addition, the direction perpendicular to the first direction X and the second direction Y is referred to as the "third direction Z."

[0039] In addition, in describing the configuration of the cleaning member 3, the direction indicating the width is defined as the "width direction x (hereinafter, x direction)", the direction indicating the length is defined as the "length direction y (hereinafter, y direction)", and the direction indicating the thickness and perpendicular to the xy plane (plane including the x and y directions) is defined as the "thickness direction z (hereinafter, z direction)". The x and y directions intersect (specifically, are perpendicular to) each other. In addition, in FIG. 1, the x direction corresponds to the first direction X, the y direction corresponds to the second direction Y, and the z direction corresponds to the third direction Z.

[0040] In the following description, in the x direction, one side is referred to as the x1 side, and the other side is referred to as the x2 side. In the y direction, one side is referred to as the y1 side, and the other side is referred to as the y2 side. The y1 side corresponds to the base end side of the cleaning member 3, and the y2 side corresponds to the tip end side of the cleaning member 3. In addition, in Figures 2 and 3, the cleaning member 3 is arranged so that the x1 side corresponds to the left side, the x2 side corresponds to the right side, the y1 side corresponds to the upper side, and the y2 side corresponds to the lower side.

[0041] In addition, the area closer to the center than the ends on the x1 and x2 sides is referred to as the inside in the x direction, and the ends on the x1 and x2 sides are referred to as the outside in the x direction. Furthermore, the area closer to the center than the ends in the third direction Z is referred to as the inside in the third direction Z, and the ends in the third direction Z are referred to as the outside in the third direction Z.

[0042] FIG. 1 shows a cleaning tool 1. This cleaning tool 1 is used to clean a surface A to be cleaned, such as a floor, a wall, or a ceiling (see FIG. 6). Specifically, the cleaning tool 1 is used to wipe the surface A to be cleaned. The cleaning tool 1 includes a cleaning handle member 2 and a cleaning member 3 that is detachably attached to the cleaning handle member 2. The cleaning tool 1 of this embodiment also includes a cleaning sheet 4 that is used for cleaning. Note that the cleaning tool 1 does not necessarily have to include the cleaning sheet 4.

[0043] As shown in FIG. 1, the cleaning handle member 2 includes a cleaning attachment part 20 disposed on the lower side in the second direction Y, a cleaning handle part 21 provided on the upper side in the second direction Y, and a cleaning connection part 22 connecting the cleaning attachment part 20 and the cleaning handle part 21. Therefore, in the cleaning handle member 2, the cleaning attachment part 20 is disposed on the lower end side, and the cleaning handle part 21 is disposed on the upper end side of the cleaning attachment part 20. The cleaning handle member 2 of this embodiment is made of polycarbonate ABS resin (PC-ABS) except for the boss pin used to connect the cleaning attachment part 20 and the cleaning connection part 22. Note that the material constituting the cleaning handle member 2 is not limited to the above, and may be other than polycarbonate ABS resin (PC-ABS).

[0044] The cleaning attachment part 20 is for attaching the cleaning member 3 and the cleaning sheet 4 to the cleaning handle member 2. The cleaning attachment part 20 of this embodiment includes an attachment main body 200 and a pair of gripping parts 201, 201 (see FIG. 6 ) that grip the cleaning member 3 and the cleaning sheet 4 in the third direction Z.

[0045] As shown in Fig. 6, the mounting body 200 of this embodiment is configured so that the cleaning member 3 (specifically, the base end edge portion 310 described later) can be inserted from below. The mounting body 200 of this embodiment is provided with insertion holes 200a at both ends in the first direction X. The mounting body 200 of this embodiment further includes a grip mounting portion 200b for mounting a grip portion 201 described later. A pair of the grip mounting portions 200b are provided on the lower side of the mounting body 200, and the pair of grip mounting portions 200b, 200b face each other in the third direction Z. Therefore, the mounting body 200 of this embodiment is configured to be U-shaped when viewed in the left-right direction.

[0046] The pair of gripping parts 201, 201 each have a symmetrical shape. As shown in FIG. 6, the pair of gripping parts 201, 201 are attached to the gripping attachment parts 200b, 200b in a state in which they can rotate around the first direction X (within the YZ plane). Therefore, the pair of gripping parts 201, 201 are configured to be switchable between a state in which they approach each other in the third direction Z and a state in which they move apart in the third direction Z by rotating around the first direction X. The pair of gripping parts 201, 201 are provided with protruding parts that protrude inward in the third direction Z when they approach each other in the third direction Z. The protruding parts in this embodiment include a gripping protruding part 201a that protrudes toward the gripping part 201 on the opposite side, and an inclined protruding part 201b that protrudes so as to incline upward as it approaches the inside of the third direction Z. In this embodiment, the gripping protruding part 201a is disposed below the inclined protruding part 201b. The tip of the inclined protruding portion 201b in the direction protruding from the gripping portion 201 is configured to have an uneven shape.

[0047] As shown in FIG. 1, the cleaning handle 21 includes a shaft 210 extending in the second direction Y and a handle body 211 held by the user during cleaning. The shaft 210 of this embodiment is tubular (specifically, cylindrical) along the second direction Y. The handle body 211 of this embodiment is a square tube (specifically, an octagonal tube). The handle body 211 of this embodiment is tapered so that the outer diameter becomes smaller toward the bottom. This makes it easy for the user to hold the handle body 211. The handle body 211 is disposed above the shaft 210 and is connected to the shaft 210. The handle body 211 (specifically, the upper end of the handle body 211) constitutes the upper end 10 of the cleaning tool 1. The handle body 211 is shorter than the shaft 210 in the second direction Y. Moreover, the outer diameter of the handle body 211 is larger than the outer diameter of the shaft portion 210 .

[0048] The cleaning connection part 22 is for connecting the cleaning attachment part 20 and the cleaning handle part 21. The cleaning attachment part 20 is connected to the lower side of the cleaning connection part 22, and the cleaning handle part 21 is connected to the upper side of the cleaning connection part 22, thereby connecting the cleaning attachment part 20 and the cleaning handle part 21. In this embodiment, the cleaning connection part 22 and the cleaning attachment part 20 are connected to be rotatable around the third direction Z (within the XY plane). Therefore, for example, the cleaning attachment part 20 can be rotated relative to the cleaning connection part 22 in the direction of the arrow shown in FIG. 1.

[0049] The cleaning sheet 4 is for adhering dust accumulated on the surface A to be cleaned when the cleaning member 3 is used. The cleaning sheet 4 may have, for example, adhesiveness, and dust may be attached to the cleaning sheet 4 using the adhesiveness, or dust may be attached to the cleaning sheet 4 using static electricity. The cleaning sheet 4 is made of, for example, nonwoven fabric or paper. The cleaning sheet 4 may be in a dry state or in a wet state impregnated with a cleaning liquid or the like. The cleaning sheet 4 may be used repeatedly by cleaning the cleaning sheet 4 itself after adhering dust, or may be disposable. The cleaning sheet 4 is detachably attached to the cleaning member 3 described later.

[0050] The cleaning member 3 is a member that constitutes the head of the cleaning tool 1. As shown in Figs. 2 and 3, the cleaning member 3 is a plate-like member that extends in the xy plane. The cleaning member 3 of this embodiment is flat. The cleaning member 3 of this embodiment is a quadrangular shape (specifically, a rectangular shape) in which the length in the x direction is longer than the length in the y direction when viewed from the front. The cleaning member 3 of this embodiment has a constant thickness except for a base end edge portion 310 described later. The thickness of the cleaning member 3 is preferably in the range of 0.5 to 5 mm, and more preferably 0.5 to 3 mm. Typically, the thickness of the cleaning member 3 of this embodiment is 1 mm.

[0051] 2, the cleaning member 3 includes a cleaning main body 30 and a cleaning edge 31 that maintains the shape of the cleaning main body 30. In this embodiment, the cleaning main body 30 and the cleaning edge 31 are integrally formed. In this embodiment, the cleaning main body 30 and the cleaning edge 31 have approximately the same length in the x direction.

[0052] First, a description will be given of the cleaning edge portion 31. The cleaning edge portion 31 includes a base end edge portion 310 disposed on the y1 side, and a tip end edge portion 311 disposed on the y2 side.

[0053] The base end edge 310 is the end of the cleaning member 3 on the y1 side. This base end edge 310 extends in the x direction. The base end edge 310 of this embodiment is used when attaching the cleaning member 3 to the cleaning handle member 2. Therefore, the base end edge 310 of this embodiment is provided with a protruding portion 310a protruding outward in the x direction and a convex portion 310b provided on the xy plane. Note that the base end edge 310 may be provided with a configuration other than the protruding portion 310a and the convex portion 310b that is used when attaching the cleaning member 3 to the cleaning handle member 2. Also, the base end edge 310 does not need to be provided with a configuration used when attaching the cleaning member 3 to the cleaning handle member 2.

[0054] The protrusions 310a are provided on the x1 and x2 sides of the base end edge 310. The protrusions 310b are configured so that the tips in the direction protruding from the base end edge 310 are concave. Therefore, the protrusions 310b are concave (specifically, concave, curved toward the base end edge 310) when viewed in the width direction (see FIG. 6). The protrusions 310b are provided on both sides in the z direction. Note that multiple protrusions 310b (specifically, two) in this embodiment are arranged in the x direction.

[0055] As shown in FIG. 2, the tip edge 311 is an end of the cleaning member 3 on the y2 side. This tip edge 311 extends in the x direction. This tip edge 311 constitutes the lower end 11 of the cleaning tool 1. In the present embodiment, both ends in the x direction of the tip edge 311 are chamfered, and the corners are rounded. The tip edge 311 is disposed on the tip side of the cleaning main body 30 described later. In addition, the tip edge 311 in this embodiment is shorter in the y direction than the base end edge 310 and the cleaning main body 30. Note that the tip edge 311 may be longer than the base end edge 310 and the cleaning main body 30 in the y direction.

[0056] As an example, the cleaning main body 30 is configured in a lattice shape. As shown in Figures 2 and 3, the cleaning main body 30 includes an inclined line portion 300 inclined with respect to the x direction, an intersection line portion 301 intersecting the inclined line portion 300, and an intersection portion and component surface portion 30a formed by the intersection of the inclined line portion 300 and the intersection line portion 301.

[0057] The inclined line portion 300 is a member (in this embodiment, a linear member) extending in a direction inclined with respect to the x direction (hereinafter, inclined direction). Here, the inclined direction in this embodiment is a direction approaching the y2 side as it approaches the x2 side from the x1 side. In this embodiment, multiple (specifically, nine) inclined line portions 300 are arranged parallel to each other in the xy plane. Also, in this embodiment, all the inclined line portions 300 are arranged at equal intervals in the y direction. Note that all the inclined line portions 300 may be spaced at unequal intervals.

[0058] At least one end of the inclined line portion 300 in the inclination direction is a free end. As shown in Fig. 3, in this embodiment, the inclined line portion 300 includes the same number (specifically, three each) of one-side inclined line portion 300a whose x2 side is a free end, other-side inclined line portion 300b whose x1 side is a free end, and intermediate inclined line portion 300c whose x1 side and x2 side are free ends. Note that the numbers of one-side inclined line portion 300a, other-side inclined line portion 300b, and intermediate inclined line portion 300c may be different.

[0059] In FIG. 3, the inclined line portion 300 (specifically, the one inclined line portion 300a, the other inclined line portion 300b, and the spaced inclined line portion 300c) are indicated by dashed dotted lines.

[0060] One inclined line portion 300a is disposed on the y1 side, and its x1 side is connected to the base edge portion 310. The other inclined line portion 300b is disposed on the y2 side, and its x2 side is connected to the tip edge portion 311. Furthermore, the intermediate inclined line portion 300c is disposed between the one inclined line portion 300a and the other inclined line portion 300b in the y direction, and extends across the x1 side and the x2 side.

[0061] The intersecting line portion 301 is a member (a linear member in this embodiment) that extends in a direction intersecting the inclination direction (hereinafter, the intersecting direction). Here, the intersecting direction in this embodiment is a direction approaching the y1 side as it approaches the x2 side from the x1 side. Therefore, the intersecting direction in this embodiment is a direction that intersects with the x direction in addition to the inclination direction. Also, in this embodiment, the intersection angle of the intersecting direction with respect to the x direction is the same as the inclination angle of the inclination direction with respect to the x direction.

[0062] In this embodiment, multiple (specifically, nine) intersecting line portions 301 are arranged in parallel in the xy plane. In this embodiment, all intersecting line portions 301 are arranged at equal intervals in the y direction. All intersecting line portions 301 may be spaced at unequal intervals. Furthermore, in this embodiment, the distance between the inclined line portions 300 and the distance between the intersecting line portions 301 in the y direction are the same. The distance between the inclined line portions 300 and the distance between the intersecting line portions 301 may be different.

[0063] At least one end of the crossing line portion 301 in the crossing direction is a free end. In this embodiment, the crossing line portion 301 includes the same number (specifically, three each) of one-side crossing line portion 301a whose x1 side is a free end, other-side crossing line portion 301b whose x2 side is a free end, and intermediate crossing line portion 301c whose x1 side and x2 side are free ends. The numbers of one-side crossing line portion 301a, other-side crossing line portion 301b, and intermediate crossing line portion 301c may be different.

[0064] In FIG. 3, the intersecting line portions 301 (specifically, one intersecting line portion 301a, the other intersecting line portion 301b, and the inter-arranged intersecting line portion 301c) are indicated by dashed lines.

[0065] One intersecting line portion 301a is disposed on the y1 side, and the x2 side is connected to the base end edge portion 310. The other intersecting line portion 301b is disposed on the y2 side, and the x1 side is connected to the tip end edge portion 311. The intermediate intersecting line portion 301c is disposed between the one intersecting line portion 301a and the other intersecting line portion 301b in the y direction, and extends between the x1 side and the x2 side.

[0066] The intersecting line portion 301 intersects with the inclined line portion 300. In this embodiment, the intersecting line portion 301 intersects with the inclined line portion 300 on the outer side in the x direction and on the inner side in the x direction.

[0067] The intersection portion is formed by the intersection of an inclined line portion 300 and an intersecting line portion 301. In this embodiment, a plurality of inclined line portions 300 intersect with a plurality of intersecting line portions 301, and thus a plurality of intersection portions are provided. As shown in Fig. 3, the intersection portion includes an intersecting end portion 30A and an intersecting portion 30D disposed on the inside of the intersecting end portion 30A in the x direction.

[0068] The intersecting end 30A is a portion where the inclined line portion 300 (specifically, the free end of the inclined line portion 300) and the intersecting line portion 301 (specifically, the free end of the intersecting line portion 301) intersect on the outside in the x direction. As shown in Figs. 3 and 4, the intersection of the dashed lines on the x1 side and the x2 side is the intersecting end 30A. In addition, a plurality of (specifically, six) intersecting end portions 30A are arranged side by side in the y direction. Here, in this embodiment, the inclined line portion 300 and the intersecting line portion 301 form a substantially V-shaped space 30B at the end portions on the x1 side and the x2 side of the cleaning main body 30. Therefore, the plurality of intersecting end portions 30A are arranged side by side in the y direction with the space 30B between them. Note that the space 30B may be formed with respect to the cleaning main body 30 so as to extend from the end portions on the x1 side and the x2 side toward the inside in the x direction. Therefore, the shape of the space 30B is not limited to a substantially V-shape, and may be, for example, a shape in which the length in the y direction is substantially the same from the outer side in the x direction to the inner side in the x direction (i.e., a U-shape or a C-shape). Furthermore, when the space 30B is V-shaped, the space 30B may have rounded corners on the inner side in the x direction, as shown in Figures 2 to 4.

[0069] As shown in FIG. 4, in this embodiment, the end 30C in the width direction is disposed outside the intersecting end 30A in the x direction. The end 30C in the width direction is the end on the x1 side and the x2 side of the cleaning body 30. The end 30C in the width direction in this embodiment is chamfered and has rounded corners. Furthermore, a plurality of the end 30C in the width direction is disposed in the y direction with a space 30B therebetween. Thus, the end 30C in the width direction is discontinuous in the y direction. Furthermore, each end 30C in the width direction is configured to be identical. And each end 30C in the width direction is at the same position in the x direction.

[0070] Intersection portion 30D is a portion where inclined line portion 300 and intersection line portion 301 intersect, on the inside in the x-direction of intersection end portion 30A. As shown in Figures 3 and 5, the intersection of the dashed and dotted lines, on the inside in the x-direction of intersection end portion 30A, is intersection portion 30D.

[0071] A plurality of intersecting portions 30D are arranged on the xy plane. In this embodiment, the plurality of intersecting portions 30D are arranged so as to be aligned in the y direction. The plurality of intersecting portions 30D are also arranged so as to be aligned in the x direction. The plurality of intersecting portions 30D may be aligned in the y direction at substantially the same position in the x direction, or may be aligned in the y direction at different positions in the x direction. The plurality of intersecting portions 30D may be aligned in the x direction at substantially the same position in the y direction, or may be aligned in the x direction at different positions in the y direction. As shown in FIG. 3, in this embodiment, a plurality of rows of intersecting portions 30D arranged in the y direction (specifically, five rows) are arranged in the x direction. That is, the row of intersecting portions 30D located closest to the x1 side in the x direction is defined as the first row, and the second row to the fifth row are aligned in the x direction toward the x2 side. The distance between the intersecting portions 30D, 30D in the y direction in each row is the same.

[0072] In this embodiment, the number of inter-crossing portions 30D in the odd-numbered rows (specifically, seven) is greater than the number of inter-crossing portions 30D in the even-numbered rows (specifically, six). The inter-crossing portions 30D in the even-numbered rows are located between the inter-crossing portions 30D, 30D adjacent to each other in the y direction in the odd-numbered rows on the x1 or x2 side of the inter-crossing portions 30D in the odd-numbered rows. Specifically, in the y direction, the inter-crossing portions 30D in the even-numbered rows are located at positions equivalent to approximately the center of the distance between the inter-crossing portions 30D, 30D adjacent to each other in the y direction in the odd-numbered rows. Also, the distances between the inter-crossing portions 30D in the even-numbered rows and the inter-crossing portions 30D in the odd-numbered rows in the inclination direction and the crossing direction are equal to each other.

[0073] The inter-intersection portions 30D in the odd-numbered rows are arranged adjacent to each other in the x direction. The inter-intersection portions 30D in the even-numbered rows are arranged adjacent to each other in the x direction. In this embodiment, the separation distance between the inter-intersection portions 30D in the odd-numbered rows is the same as the separation distance between the inter-intersection portions 30D in the even-numbered rows in the x direction. Therefore, in this embodiment, the separation distance between the inter-intersection portions 30D in the x direction is the same. Note that in this embodiment, the separation distance between the inter-intersection portions 30D in the x direction is longer than the separation distance between the inter-intersection portions 30D in the y direction.

[0074] In this embodiment, the inter-crossing portions 30D in the even-numbered rows are arranged at the same positions as the inter-crossing ends 30A in the y direction. The number of inter-crossing portions 30D in the even-numbered rows is the same as the number of inter-crossing ends 30A arranged in the y direction. Therefore, in the x direction, the inter-crossing portion 30D in the second row is arranged adjacent to the inter-crossing end 30A on the x1 side, and the inter-crossing portion 30D in the fourth row is arranged adjacent to the inter-crossing end 30A on the x2 side.

[0075] In this embodiment, the intersecting end portion 30A is also disposed at a position that is half the distance between the intersecting portions 30D, 30D adjacent to each other in the longitudinal direction x in the odd-numbered rows. The distance between the intersecting end portion 30A and the intersecting portion 30D in the odd-numbered rows in the inclination direction and the intersecting direction is equal to the distance between the intersecting portion 30D in the even-numbered rows and the intersecting portion 30D in the odd-numbered rows in the inclination direction and the intersecting direction.

[0076] The constituent surface portion 30a is an area surrounded by a plurality of intersections. The constituent surface portion 30a of this embodiment is an area surrounded by four intersections, with the inclined line portion 300 and the intersection line portion 301 extending between the intersections as sides. Therefore, the constituent surface portion 30a is rectangular in front view. As described above, in FIG. 3, the inclined line portion 300 and the intersection line portion 301 are shown by dashed lines, and the points where the dashed lines intersect are the intersection end portion 30A and the intersecting portion 30D. Therefore, as shown in FIG. 5, the constituent surface portion 30a is an area surrounded by four intersections, with the dashed lines as sides.

[0077] As described above, the distances between the inter-crossing portions 30D of the even rows and the inter-crossing portions 30D of the odd rows are equal in the inclination direction and the crossing direction, and the distances between the inter-crossing end portion 30A and the inter-crossing portions 30D of the odd rows are equal in the inclination direction and the crossing direction. Therefore, the component surface portion 30a is a parallelogram, preferably a rhombus, in which the lengths of adjacent sides (in other words, the distance between adjacent intersections in the side direction) are the same. Also, as described above, the distance between the inter-crossing portions 30D, 30D in the x direction is longer than the distance between the inter-crossing portions 30D, 30D in the y direction. Therefore, as shown in FIG. 5, the component surface portion 30a of this embodiment is a rhombus in which the diagonal line in the x direction is longer than the diagonal line in the y direction.

[0078] 5, the component surface portion 30a has a first corner portion located on one diagonal of a parallelogram (specifically, a diamond shape) and a second corner portion located on the other diagonal. Here, in this embodiment, one diagonal line extends in the y direction, and the other diagonal line extends in the x direction. Therefore, the first corner portion is a corner portion in the y direction, and the second corner portion is a corner portion in the x direction.

[0079] In this embodiment, the angle of the first corner is larger than the angle of the second corner. The angle of the second corner is less than 90 degrees. If the angle of the second corner exceeds 90 degrees, the cleaning main body 30 is likely to break when it is deformed around a virtual line extending in the x direction (specifically, when it is bent in the z direction). On the other hand, if the angle of the second corner is smaller than 90 degrees, the cleaning main body 30 is less likely to break. The smaller the angle of the second corner is than 90 degrees, the less likely the cleaning main body 30 is to break even if the bending radius is small, and the closer the angle of the second corner is to 90 degrees, the larger the bending radius of the cleaning main body 30 is.

[0080] 3 and 5, the cleaning body 30 of this embodiment has a through hole penetrating in the z direction within an area surrounded by four intersections. Therefore, the constituent surface portion 30a of this embodiment is a through hole penetrating the cleaning body 30 in the z direction.

[0081] As shown in Fig. 5, the through hole of this embodiment has a diamond shape with a length in the x direction longer than the length in the y direction. The through hole has a length corner 30c located diagonally in the y direction and a width corner 30d located diagonally in the x direction. Therefore, in this embodiment, in the through hole which is the component surface portion 30a, the length corner 30c is a first corner and the width corner 30d is a second corner. The length corner 30c and the width corner 30d have rounded edges.

[0082] As shown in Fig. 3, a plurality of component surface parts 30a are arranged in a line on the xy plane of the cleaning main body 30. In this embodiment, the component surface parts 30a are arranged over the entire xy plane of the cleaning main body 30. The multiple component surface parts 30a have the same shape and size. That is, the cleaning main body 30 of this embodiment has multiple through holes, and all of the through holes have the same shape and size.

[0083] In this embodiment, a row in which seven component surface portions 30a are arranged in the y direction and a row in which six component surface portions 30a are arranged in the y direction are alternately arranged in the x direction. Specifically, as shown in FIG. 3, the row of component surface portions 30a located closest to the x1 side is the first row, and the second to fifth rows are arranged toward the x2 side. In the odd-numbered rows, six component surface portions 30a are arranged in the y direction, and in the even-numbered rows, seven component surface portions 30a are arranged in the y direction. The component surface portions 30a, 30a in the even-numbered rows are arranged adjacent to each other in the x direction, and the component surface portions 30a, 30a in the odd-numbered rows are arranged adjacent to each other in the x direction. In addition, the component surface portions 30a in the even-numbered rows are arranged adjacent to the space 30B in the x direction.

[0084] In this embodiment, the odd-numbered row component surface portion 30a is arranged so that its center is located at a position corresponding to half the center distance between the even-numbered row component surface portions 30a, 30a adjacent in the x direction. Also, the even-numbered row component surface portion 30a is arranged so that its center is located at a position corresponding to the center distance between the odd-numbered row component surface portions 30a adjacent in the x direction. Therefore, in this embodiment, a part of each of the odd-numbered row component surface portions 30a and the even-numbered row component surface portions 30a is arranged at the same position in the x direction. Note that, in this embodiment, a part of the odd-numbered row component surface portion 30a and a part of the space 30B are arranged at the same position in the x direction. Furthermore, in this embodiment, a part of each of the odd-numbered row component surface portions 30a and the even-numbered row component surface portions 30a is arranged at the same position in the y direction.

[0085] The cleaning member 3 is made of a material that can be bent in the z direction and has a restoring force from a deformed shape (specifically, a bent shape) to its original shape. The material of the cleaning member 3 includes plastic or elastomer. Specifically, the material of the cleaning member 3 is at least one of polyethylene terephthalate resin (PET), polycarbonate ABS resin (PC-ABS), polypropylene resin (PP), polyvinyl chloride resin (PVC), and acrylic resin, or a combination of these. The most preferable material is either polyethylene terephthalate resin (PET) or polycarbonate ABS resin (PC-ABS), or a combination of these. In other words, when either polyethylene terephthalate resin (PET) or polycarbonate ABS resin (PC-ABS), or a combination of these, is used as the material, the cleaning member 3 is more likely to return to its original shape even if it is stored in a deformed shape for a long period of time, compared to when other materials are used. In other words, when the most preferable material is used, the shape restoring property is excellent. The cleaning member 3 of this embodiment is made of polyethylene terephthalate resin (specifically, modified PET). Therefore, the cleaning main body 30 and the cleaning edge 31 are also made of polyethylene terephthalate resin (specifically, modified PET).

[0086] Next, a method for assembling the cleaning tool 1 by attaching the cleaning member 3 and the cleaning sheet 4 to the cleaning handle 2 will be described.

[0087] When constructing the cleaning tool 1, first, the cleaning sheet 4 is attached to the cleaning member 3. Specifically, the cleaning sheet 4 is attached so as to cover the cleaning member 3 from the outside in the third direction Z, with the tip edge portion 311 being folded back in the third direction Z on the tip side of the cleaning member 3.

[0088] Next, as shown in FIG. 6, the cleaning member 3 is attached to the cleaning attachment part 20. In this embodiment, first, the pair of gripping parts 201, 201 are put in a state of being apart in the third direction Z. Then, the base end edge part 310 is inserted into the attachment main body part 200 from the lower side. At this time, the protruding part 310a is inserted into the insertion hole 200a. Next, the pair of gripping parts 201, 201 are rotated around the first direction X to switch to a state of approaching in the third direction Z, and the pair of gripping parts 201, 201 grip the cleaning member 3 and the cleaning sheet 4. Specifically, the inclined protruding part 201b is brought into contact with the convex part 310b via the cleaning sheet 4, and the gripping protruding parts 201a, 201a grip the cleaning sheet 4 and the cleaning member 3 from the outside in the third direction Z. Thus, the cleaning member 3 is attached to the cleaning attachment part 20, and the cleaning tool 1 is configured. The cleaning member 3 and the cleaning handle member 2 are detachable.

[0089] As shown in Fig. 6, when cleaning is performed with the cleaning tool 1, the cleaning member 3 is brought into contact with the surface A to be cleaned from the tip edge 311 side, and the cleaning main body 30 is bent in the z direction. Specifically, the cleaning main body 30 is brought into contact with the surface A to be cleaned in the z direction via the cleaning sheet 4, and the intersections (specifically, the intersection end 30A and the intersection portion 30D) are bent around an imaginary line extending in the x direction, whereby the cleaning main body 30 is bent in the z direction. Thus, the surface direction of the cleaning member 3 can be brought into contact with the surface A to be cleaned.

[0090] As described above, according to this embodiment, when the cleaning member 3 is brought into contact with the surface A to be cleaned, the structural surface portion 30a distributes the deformation force (specifically, bending force) applied to the cleaning main body 30 within the cleaning main body 30, thereby reducing the burden applied to the cleaning main body 30. Therefore, the cleaning main body 30 can be easily deformed and difficult to break. Here, the structural surface portion 30a of this embodiment is configured as a through hole. Therefore, when bending the cleaning member 3, no bending force is applied to the through hole, so the cleaning member 3 is easy to bend. Therefore, when the cleaning sheet 4 is attached to the cleaning member 3, the cleaning sheet 4 can reliably capture dust on the surface A to be cleaned. Furthermore, the cleaning main body 30 has a plurality of structural surface portions 30a. Therefore, the cleaning main body 30 is even easier to bend.

[0091] Furthermore, in this embodiment, the bending force applied to the cleaning main body 30 by the constituent surface portion 30a is distributed within the cleaning main body 30, and the cleaning member 3 is made of a material that has the ability to restore its original shape from a deformed shape, which has a synergistic effect, so that the cleaning member 3 has the toughness to withstand deformation caused by rough usage and the shape retention to prevent deformation even during rough storage.

[0092] In this embodiment, the constituent surface parts 30a are arranged in a line in the y direction. Therefore, the cleaning member 3 can be easily bent in the z direction from any part in the y direction. In particular, in this embodiment, the constituent surface parts 30a are located throughout the y direction, so that the cleaning main body 30 can be easily bent in the z direction from any part.

[0093] In this embodiment, the constituent surface parts 30a in the even-numbered rows are arranged adjacent to each other in the x direction, and the constituent surface parts 30a in the odd-numbered rows are arranged adjacent to each other in the x direction. Therefore, when the cleaning main body 30 is bent in the z direction around a virtual line extending in the x direction, the bending force can be dispersed within the cleaning main body 30 by the multiple constituent surface parts 30a arranged adjacent to each other in the x direction. This makes it even easier to bend the cleaning main body 30 and less likely to break.

[0094] In this embodiment, the distance at which the inclined line portions 300 are spaced apart in the y direction is the same as the distance at which the intersecting line portions 301 are spaced apart in the y direction. Here, the size of the constituent surface portion 30a can be adjusted by adjusting the distance between the inclined line portions 300 and the distance between the intersecting line portions 301. Thus, the rigidity of the entire cleaning main body 30 can be adjusted by adjusting the size of the constituent surface portion 30a.

[0095] In addition, the constituent surface part 30a in this embodiment is rhombus-shaped. Therefore, for example, the cleaning main body part 30 can be bent in a twisted manner by contacting the cleaning main body part 30 with the surface A to be cleaned while the side of the constituent surface part 30a extending in the inclined direction or the intersecting direction is parallel to the surface direction of the surface A. In other words, the cleaning main body part 30 can be bent in various ways.

[0096] In this embodiment, a part of each of the component surface parts 30a in the odd-numbered rows and the even-numbered rows is arranged at the same position in the x direction. Therefore, the interval between the component surface parts 30a in the odd-numbered rows and the even-numbered rows can be made small, so that the cleaning main body 30 can have more component surface parts 30a. Therefore, the cleaning main body 30 can be easily bent.

[0097] In this embodiment, the angle of the second corner is less than 90 degrees. Therefore, when bending the cleaning body 30 around a virtual line extending in the x-direction, the second corner easily distributes the bending force within the cleaning body 30, and as a result, the cleaning body 30 in the bent shape is less likely to crack.

[0098] In addition, in this embodiment, the widthwise ends 30C are discontinuous in the y direction. Therefore, for example, when a force in the z direction is applied to a part of the widthwise ends 30C, the force in the z direction is transmitted by detouring the inclined line portion 300 and the intersecting line portion 301, so that the force in the z direction can be released without being transmitted to the entire area of ​​all the widthwise ends 30C arranged in the y direction. Furthermore, when the cleaning main body 30 is bent in the z direction around a virtual line extending in the x direction, one widthwise end 30C is not influenced by the other widthwise end 30C, so the cleaning member 3 is easily bent. Furthermore, when the cleaning main body 30 is bent in a twisted manner, a bending force is not applied to all the x-direction ends 30C, so the cleaning main body 30 is resistant to twisting. Therefore, the cleaning main body 30 is easily bent in a twisted manner.

[0099] In addition, the end 30C in the width direction in this embodiment is chamfered and the corners are rounded. This can prevent, for example, the cleaning sheet 4 from getting caught on the cleaning main body 30. In addition, in the tip edge portion 311 of this embodiment, both ends in the x direction are chamfered and the corners are rounded. This can prevent the cleaning sheet 4 from getting caught when attaching the cleaning sheet 4 to the cleaning member 3, specifically, when folding back the cleaning sheet 4 using the tip edge portion 311.

[0100] In this embodiment, the ends 30C in the width direction are arranged at the same position in the x direction. Therefore, the ends 30C in the width direction are arranged in an orderly manner, which improves the appearance of the cleaning main body 30.

[0101] Moreover, the cleaning member 3 of this embodiment is made of polyethylene terephthalate resin (specifically, modified PET). Therefore, after the intersection is bent around a virtual line extending in the x direction, the intersection can return to its original shape by a restoring force.

[0102] In addition, the cleaning member 3 in this embodiment is flat. Therefore, the cleaning sheet 4 can be easily aligned with the cleaning member 3.

[0103] In this embodiment, the cleaning edge 31 is located on each of the y1 side and the y2 side of the cleaning main body 30. The cleaning edge 31 includes a base edge 310 and a tip edge 311. Therefore, the shape of the cleaning main body 30 can be maintained on each of the y1 side and the y2 side. This makes it difficult to bend the cleaning main body 30 in the z direction so that the x1 side and the x2 side are brought closer to each other.

[0104] Furthermore, in this embodiment, by bringing the inclined protrusion 201b into contact with the convex portion 310b, the inclined protrusion 201b and the convex portion 310b can prevent the cleaning sheet 4 from shifting relative to the cleaning member 3. Specifically, since the tip of the inclined protrusion 201b is uneven, the inclined protrusion 201b bites into the cleaning sheet 4 during cleaning, preventing the cleaning sheet 4 from shifting relative to the cleaning member 3.

[0105] The present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit and scope of the present invention.

[0106] In the above embodiment, the cleaning member 3 is attached to the cleaning attachment part 20 by being inserted into the attachment main body 200 and gripped by the pair of grip parts 201, 201. However, this is not limited to the above, and the cleaning member 3 may be attached to the cleaning handle member 2 in a manner other than being inserted into the attachment main body 200 and gripped by the pair of grip parts 201, 201. Therefore, the cleaning attachment part 20 may have a configuration other than the configuration including the attachment main body 200 and the pair of grip parts 201, 201.

[0107] The cleaning member 3 in the above embodiment has a rectangular shape with the length in the x direction longer than the length in the y direction. However, the cleaning member 3 is not limited to this, and may have a rectangular shape with the length in the x direction shorter than or equal to the length in the y direction. Furthermore, the cleaning member 3 may have a shape other than a rectangular shape.

[0108] In the above embodiment, the cleaning member 3 is rectangular. Therefore, the length of the cleaning member 3 in the x direction is constant throughout the entire area in the y direction. However, the present invention is not limited to this, and the cleaning member 3 may be configured so that the length in the x direction becomes shorter from one of the y1 side and the y2 side to the other. This allows the contact area of ​​the cleaning member 3 with the surface A to be cleaned to be changed between the y1 side and the y2 side. In this case, the cleaning member 3 may be, for example, trapezoidal or semicircular in front view. Also, for example, the cleaning member 3 is configured so that the length in the x direction is longer toward the y2 side, thereby increasing the contact area of ​​the y2 side that first comes into contact with the surface A to be cleaned during cleaning. Therefore, when the cleaning sheet 4 is attached to the cleaning member 3, more dust can be attached to the cleaning sheet 4.

[0109] In the above embodiment, the cleaning member 3 has a constant thickness except for the base end edge portion 310. Therefore, the cleaning main body 30 is also configured to have a constant thickness throughout the entire area. However, this is not limited to this, and the cleaning main body 30 may be configured to have a different thickness in the y direction. This allows the cleaning main body 30 to change its deformation strength (specifically, bending strength) in the y direction. In this case, the thickness of the cleaning main body 30 may be adjusted so that the minimum thickness is 0.5 mm and the maximum thickness is 5.0 mm. In addition, for example, the cleaning main body 30 may be configured to have a thinner thickness from the y1 side to the y2 side. This makes it easier to bend the y2 side of the cleaning main body 30. Furthermore, the cleaning edge portion 31 and the cleaning main body 30 may be configured to have different thicknesses. For example, by making the thickness of the cleaning edge portion 31 thicker than the thickness of the cleaning main body 30, the bending of the cleaning main body 30 can be accentuated.

[0110] In the above embodiment, the inclined line portion 300 has at least one free end. However, the present invention is not limited to this. The inclined line portion 300 may have both ends in the inclined direction connected to the base end edge portion 310 and the tip end edge portion 311, so that the inclined line portion 300 is a fixed end. The same applies to the intersecting line portion 301.

[0111] In the above embodiment, the inclined line portion 300 includes the spaced inclined line portion 300c. However, this is not limited thereto, and for example, the inclined line portion 300 does not have to include the spaced inclined line portion 300c. Also, the crossing line portion 301 does not have to include the spaced crossing line portion 301c.

[0112] In the above embodiment, the multiple component surface portions 30a have the same shape and size over the entire cleaning main body 30. However, this is not limited to the above, and the multiple component surface portions 30a may have different shapes or sizes. In this case, the size of the component surface portions 30a may be changed depending on the position, and for example, the component surface portion 30a arranged on the y1 side, which is one side in the y direction, may be larger than the component surface portion 30a arranged on the y2 side, which is the other side in the y direction.

[0113] In the above embodiment, the inclined line portion 300 is a straight member extending in the inclined direction. However, the present invention is not limited to this, and for example, the inclined line portion 300 may be a curved line member curved on the xy plane. The same applies to the intersecting line portion 301. That is, at least one of the inclined line portion 300 and the intersecting line portion 301 may be curved. This allows many variations in the shape pattern of the constituent surface portion 30a. In addition, the inclined line portion 300 and the intersecting line portion 301 may be configured to be curved in the thickness direction z.

[0114] In the above embodiment, the multiple inclined line portions 300 are arranged parallel to each other in the y and x directions. However, this is not limited thereto, and for example, one inclined line portion 300 may be a straight member extending in the inclined direction, and the other inclined line portion 300 may be a curved linear member extending in the inclined direction, so that the multiple inclined line portions 300 extending in the inclined direction are arranged substantially parallel to each other in the y and x directions. The same is true for the intersecting line portion 301. Moreover, the multiple inclined line portions 300 and the multiple intersecting line portions 301 do not have to be arranged parallel to each other in the xy plane.

[0115] In the above embodiment, all the inclined line portions 300 are arranged at equal intervals in the y direction. However, this is not limiting, and for example, the distances between the inclined line portions 300 may be different. The same applies to the intersecting line portions 301.

[0116] Also, for example, the inclination angle with respect to the x direction may be different between one inclined line portion 300 and another inclined line portion 300. The same applies to the intersecting line portion 301.

[0117] In the above embodiment, the crossing angle of the cross direction with respect to the x direction is the same as the inclination angle of the inclination direction with respect to the x direction. However, this is not limited to this, and the crossing angle of the cross direction with respect to the x direction may be different from the inclination angle of the inclination direction with respect to the x direction.

[0118] In the above embodiment, the intersecting direction is a direction that intersects with the x direction in addition to the tilt direction, but is not limited to this, and may be, for example, a direction that is parallel to the x direction.

[0119] In the above embodiment, the constituent surface portion 30a is a through hole. However, this is not limited thereto, and for example, the constituent surface portion 30a may be composed of a through hole and a blocking plate portion that blocks the through hole and has a thickness smaller than that of the inclined line portion 300 and the intersecting line portion 301. In this case, the blocking plate portion may be formed integrally with the inclined line portion 300 and the intersecting line portion 301. Also, a through hole may not be formed in an area surrounded by a plurality of intersecting portions, and the constituent surface portion 30a may be an area closed in the z direction.

[0120] In the above embodiment, the component surface portion 30a is a diamond-shaped through hole, but the present invention is not limited to this, and the component surface portion 30a may be a circular or sector-shaped through hole. Also, the shape and size of each through hole may be different.

[0121] In the above embodiment, the odd-numbered row component surface portion 30a is located between adjacent even-numbered row component surface portions 30a on the x1 or x2 side of the even-numbered row component surface portion 30a. That is, in the above embodiment, the odd-numbered row component surface portion 30a and the even-numbered row component surface portion 30a are not arranged adjacent to each other in the x direction. However, this is not limited to this, and for example, the odd-numbered row component surface portion 30a and the even-numbered row component surface portion 30a may be arranged adjacent to each other in the x direction. In this case, it is considered that the odd-numbered row component surface portion 30a is arranged adjacent to the space 30B in the x direction.

[0122] In the above embodiment, the cleaning member 3 is flat, but the present invention is not limited thereto, and the cleaning member 3 may be curved in shape, for example, with a portion of the xy plane protruding in the z direction more than the other portion.

[0123] In the above embodiment, the length corner 30c and the width corner 30d are rounded. However, the present invention is not limited to this. The length corner 30c and the width corner 30d may have chamfered edges, or may be corners that are not chamfered or rounded. As shown in FIG. 7, for example, the width corner 30d may have a circular hole that continues to the diamond-shaped component surface portion 30a. This can increase the durability of the component surface portion 30a when the cleaning main body 30 is bent around a virtual line extending in the x direction. This circular hole is larger than the corner of the length corner 30c. A circular hole may be formed in the width corner 30d.

[0124] In the above embodiment, the constituent surface portion 30a is rhombus-shaped with the diagonal in the x direction longer than the diagonal in the y direction. However, the present invention is not limited to this, and the constituent surface portion 30a may be rhombus-shaped with the diagonal in the y direction longer than the diagonal in the x direction. By adjusting the angle of the second corner, the cleaning main body 30 can be made to be easily or not easily broken.

[0125] In the above embodiment, various resins are listed as the material of the cleaning member 3. Specific examples of the various resins include foamed polypropylene resin (foamed PP), low foamed polyvinyl chloride resin (low foamed PVC), and hard polyvinyl chloride (hard chlorinated PVC).
