[0060]

In addition, each of the two second protrusions 159 and each of the first two recessed parts 157 are configured to engage with each other in the closed position of the clamping portion 123. In addition, each of the two second recessed parts 161 and each of the two first protruding parts 155 made with the possibility of engagement with each other in the closed position of the clamping part 123.

[0061]

In addition, marks 167 (mark 167a and mark 167b) for aligning the position of one end portion 33 with the position of the other end portion 35 of the cleaning sheet 31 are respectively located between the two first recessed portions 157 of the first inner surface 129 of the first clamping portion 125 and between the two second projecting portions 159 of the second inner surface 139 of the second clamping portion 135.

[0062]

Each of the first clamp portion 125 and the second clamp portion 135 is provided with a locating lug 169 and a locating recess 171 configured to ensure that the clamp portion 123 is maintained in a closed position. direction L, and the locating protrusions 169 protrude outward in the longitudinal direction L and can be extended and retracted in the longitudinal direction L. In addition, the locating recesses 171, configured to mate with the locating protrusions 169, are respectively located at both ends of the second clamping portion 135, defined in the longitudinal direction L, and the mounting recesses 171 are recessed from the outside in the longitudinal direction L. The closed position of the clamping part 123 is maintained by the appropriate mating of the mounting projections 169 and the mounting recesses 171 at both ends of the first clamping part 125, defined in the longitudinal direction. nom direction L.

[0063]

Depressions 173 for unfolding the clamping portion 123 in the closed position are disposed on each of both side surfaces located at both ends of the cleaning head 3 defined in the longitudinal direction L. The depression portion 173 is disposed in the S direction along the short side at the point closer to the opening and closing end 147 than to the pivoting end 145, and the depressed portion 173 is positioned over the first hard member 133 and the first soft member 131 of the first clamp portion 125 and the second hard member 143 and the second soft member 141 of the second clamp portion 135. The bottom portion 175 of the depressed portion 173 (the portion located inside in the longitudinal direction L) includes a first solid member 133 of the first clamp portion 125 and a second solid member 143 of the second clamp portion 141. As a result, the user is likely to insert a finger into the depressed part 173 and fold out the clamping part 123 (first clamping part 1 25 and the second clamp portion 135) to ensure the open position, and the cleaning sheet 31 is likely to be attached to the cleaning head 3.

[0064]

As illustrated in FIG. 6, the staple hole 117 is provided with two staple holding portions 118 for holding that portion 201 of the staple 5 to be attached to the head. The two staple holding portions 118 are arranged to surround the periphery of the staple 5, and the diameter of the inner surface of the retaining portion 118 is greater than the diameter of the outer surface of the head attachment portion 201 (bracket 5).

[0065]

The cleaning tool 1 (cleaning head 3) is provided with a rotation suppression member, in particular a grease (illustrated by X in FIG. specifically, between the outer surface of that part 201 (brackets 5) for attaching to the head and the inner surface of the part 118 for holding the bracket). The grease increases the friction between the (not illustrated) inner surface of the bracket hole 117 and the outer surface of the bracket 5 (particularly the head attachment portion 201 and described later) and prevents the cleaning head 3 from turning too much relative to the bracket 5.

[0066]

As illustrated in FIG. 8, the shackle 5 is made of a rod-like member and is configured with a head attachment part 201 rotatably connected to the shackle hole 117, with a handle attachment part 203 and connected to the handle 7 of the cleaning tool, and with a spacer portion 205 that allows the head attachment portion 201 and the handle attachment portion 203 to be spaced apart. The head attachment portion 201, the handle attachment portion 203, and the spacer portion 205 are disposed in the virtual plane IS _B of the bracket, which is one plane.

[0067]

In the handle 7 of the cleaning tool, the connecting rod 301, the first handle portion 307, the second handle portion 309, the third handle portion 311, and the fourth handle portion 313 having the grip portion 315 are connected in this order. The connecting rod 301, the first handle part 307, the second handle part 309, the third handle part 311, and the fourth handle part 313 are configured to switch between the connected state and the separated state.

[0068]

The connecting rod 301 is a pivot portion which has a handle pivot axis RA ₃ to allow the handle 7 of the cleaning tool to pivot in a predetermined direction, and is formed by a first hinge portion 303 and a second hinge portion 305 forming a pair. The first hinge portion 303 is attached to the handle attachment portion 203, and the second hinge portion 305 is attached to the first handle portion 307. The connecting rod 301 (cleaning tool handle 7) is attached to the part 203 (brackets 5) to be connected to the handle, so that the connecting rod 301 (cleaning tool handle 7) can be rotated in the virtual plane IS _B of the bracket (i.e., so that the axis RA ₃ rotation of the handle is orthogonal to the virtual plane IS _B of the bracket).

[0069]

When using the cleaning tool 1, the user places his hands in the depressions 173 located on both side surfaces of the cleaning head 3 defined in the longitudinal direction L in the closed position, and unfolds the cleaning head 3 to the open position. As illustrated in FIG. 9, the user places the cleaning head 3 in the open position on the cleaning sheet 31 so that the first inner surface 129 and the second inner surface 139 of the clamp portion 123 (the first clamp portion 125 and the second clamp portion 135) face up.

[0070]

Next, one end portion 33 and the other end portion 35 of the cleaning sheet 31 are folded toward the first inner surface 129 and the second inner surface 139, respectively, so that one end portion 33 and the other end portion 35 of the cleaning sheet 31 are aligned with the respective marks 167a ( 167) and 167b (167) of the first clamping part 125.

[0071]

Further, as illustrated in FIG. 10, the user attaches one end portion 33 of the cleaning sheet 31 to the first slotted portion 163 located on each of the two first projecting portions 155 of the first clamp portion 125, and attaches the other end portion 35 of the cleaning sheet 31 to the second a slotted part 165 located on each of the two second projecting parts 159 of the second clamping part 135.

[0072]

Further, the first clamping portion 125 and the second clamping portion 135 are rotated about the rotation axis RA ₂ of the clamping portion at the pivoting end 145, the mounting protrusion 169 is inserted into the mounting recess 171, and as illustrated in Fig. 11, the cleaning head 3 will be in the closed position. As a result, one end portion 33 of the cleaning sheet 31 is held by the first slotted portion 163 provided on the two first protruding portions 155, and is held by the combination of the first protruding portion 155 and the second recessed portion 161 (two places in total) and by the combination of the first a recessed part 157 and a second protruding part 159 (two places in total) which are interlocked with each other. Therefore, in use, the possibility of separation of one end portion 33 of the cleaning sheet 31 from the grip portion 123 is reduced.

[0073]

Similarly, the other end portion 35 of the cleaning sheet 31 is held by the second slotted portion 165 provided on the two second protruding portions 159, and is held by the combination of the first protruding portion 155 and the second recessed portion 161 (two places in total) and by the combination of the first a recessed part 157 and a second protruding part 159 (two places in total) which are interlocked with each other. Therefore, in use, the possibility of separation of the other end portion 35 of the cleaning sheet 31 from the grip portion 123 is reduced.

[0074]

In the case where the user cleans a wide area, as illustrated in Fig. 12, the cleaning tool 1 is in the wide area cleaning mode, and the predetermined cleaning surface can be cleaned without much limitation. The first surface 37 of the cleaning sheet 31 (the surface of the cleaning head 3 on the side of the first cleaning surface 113) is used to clean the predetermined cleaning surface, and in the case that the first surface 37 becomes dirty, the predetermined cleaning surface can be cleaned by rotating the cleaning head 3 by 180 ° and using the second surface 39 of the cleaning sheet (the surface of the cleaning head 3 from the side of the second cleaning surface 115).

[0075]

In the case where the user cleans a narrow area, such as the vertical narrow area 51 illustrated in Fig. 13, the cleaning tool 1 can be used to clean a predetermined narrow area cleaning surface by the narrow area cleaning mode, in particular, the cleaning head 3 is rotated so that the direction of the plane of the cleaning head 3 (not illustrated) and the virtual plane of the bracket 5 (not illustrated) coincide with each other, and the part of the cleaning head 3 end in the longitudinal direction L (preferably the end part of the hole 117 for the bracket on the side where there is no entrance part 117a) is placed in a narrow area.

[0076]

To switch the operation mode of the cleaning tool 1 from the wide area cleaning mode to the narrow area cleaning mode, the cleaning tool 1 can be simply raised. When the cleaning tool 1 (cleaning head 3) is lifted, the center of gravity of the cleaning head 3 is in the first head area 119, so that the cleaning head 3 is likely to be brought to a vertical position with the first head area 119 facing down.

[0077]

In addition, since the cleaning tool 1 (cleaning head 3) has grease as a rotation suppression member located between the inner surface of the bracket hole 117 and the outer surface of the head attachment part 201 (brace 5), when the tool 1 is lifted for cleaning, the cleaning head 3 will be less likely to continue swinging like a pendulum and will probably stop in a vertical position.

[0078]

In addition, in the cleaning head 3 of the cleaning tool 1 according to the first embodiment, the turning end 145 is located in the S-direction defined along the short side of the cleaning head 3, the other end portion 151 of the cleaning head 3 in the first head area 119. Therefore, when the cleaning head 3 is lifted, the cleaning head 3 is moved to a vertical position so that the pivot end 145 faces downward and the open and close end 147 faces upward. Therefore, it is possible to clean the corner portion 53 of the vertical narrow area 51 by using the side surface of the cleaning head 3 from the side of the first head area 119 (the side of the turning end 145), and thus the cleaning sheet 31 is less likely to separate from the cleaning head 3.

[0079]

In the cleaning tool of the present disclosure (cleaning head of the present disclosure, use of the present disclosure), examples of the cleaning head include a head that performs cleaning without attaching a cleaning sheet, a head that performs cleaning with a cleaning sheet attached, and the like. Examples of a cleaning head for performing cleaning without attaching a cleaning sheet include a head having a brush portion, a head having a sponge portion, and the like.

[0080]

Examples of the cleaning sheet for the cleaning head to which the cleaning sheet is attached for cleaning include sheets known in the art, such as a sheet containing a nonwoven fabric, a sheet containing a tow, and the like. In addition, examples of the cleaning sheet include a dry type sheet, a wet type sheet impregnated with a chemical solution, and the like. The cleaning sheet is a cleaning sheet having one end portion and another end portion, and can be configured to be used by attaching the one end portion and the other end portion to the cleaning head. Examples thereof include a tubular cleaning sheet configured to wrap around a cleaning head. The tubular cleaning sheet is preferably used for the one-sided cleaning head described later.

[0081]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), the cleaning head is plate-shaped having a plane direction and a thickness direction, and is configured with a cleaning surface extending in a direction extending along the plane direction, and a portion for connecting with the element for turning the head and having the axis of rotation of the head, passing in the direction passing along the direction of the plane. The head rotation axis is a rotation axis for rotating the cleaning head relative to the head rotation member.

[0082]

The shape is not particularly limited as long as the plate shape provides two surface portions extending in the direction extending along the plane direction that are opposite to each other and side surface portions extending in the direction extending along the thickness direction. The shape of the surface portion when viewed in the thickness direction of the cleaning head may be a polygon such as a triangle (such as an isosceles triangle), a quadrilateral (such as a rectangle and a rhombus), a pentagon and a hexagon, and a curvilinear shape such as a round shape and an elliptical shape. . The plate shape may have a longitudinal direction and a short side direction extending in a plane direction.

[0083]

In addition, the surface portion and the side surface portion may be a flat surface as well as a curved surface (for example, a curved surface in which the central region other than both ends protrudes outward, and a curved surface in which the central region different from both ends, recessed inward), and may have an uneven structure, for example, may include one or more protruding parts, one or more recessed parts, and the like. As a result, in the case where the cleaning head is capable of holding the cleaning sheet, the cleaning sheet attached to the cleaning head is less likely to slip and the cleaning sheet is less likely to separate from the cleaning head when using the cleaning tool.

[0084]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), only one surface portion (one surface, that is, only the first cleaning surface) of these two surface portions of the cleaning head can form a cleaning surface, or two surface portions (both surfaces, that is, the first cleaning surface and the second cleaning surface) can form a cleaning surface.

[0085]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), the thickness (length in the thickness direction) of the cleaning head is not particularly limited, and the thickness is preferably small, and the thickness is preferably 3.0 cm or less, more preferably 2.0 cm or less for narrow area cleaning reasons. For reasons related to the strength of the cleaning tool, the thickness is preferably 0.1 cm or more, and more preferably 1.0 cm or more. The thickness of the cleaning head refers to the thickness of the thickest part of the cleaning head.

[0086]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), the cleaning head is divided into the first head area and the second head area by a virtual plane that passes through the head rotation axis located in the head rotation member attachment portion. , and extends in the thickness direction of the cleaning head. The cleaning head has the center of mass of the cleaning head located in the first area of the head. Preferably, the cleaning tool is provided with the center of mass of the cleaning head such that the first cleaning head area moves downward and the second cleaning head area moves upward in a state in which the rotation axis of the cleaning head is held in a horizontal direction and the cleaning head is not fixed. This is due to vertical surface cleanability considerations and vertical narrow zone cleanability considerations.

[0087]

The position of the center of mass of the cleaning head in the first head region and the second head region can be adjusted by changing the mass of the elements constituting the cleaning head, such as the soft element and the hard element. In addition, the position of the center of mass of the cleaning head can be adjusted by placing an additional element such as a weight or the like in the first area of the head. Examples of the cargo material include metal (eg, iron, stainless steel, lead, copper, and magnet), rubber, plastic, and the like.

[0088]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), the (cleaning head) portion for attaching the head turning member is not particularly limited, as long as the portion for attaching the head turning member includes a head rotation axis extending in a direction extending along the direction of the cleaning head plane, and can make the cleaning head and the head rotation member rotatably coupled.

[0089]

The preferred configuration of the head turning member will be described later, and examples of the head turning member attachment portion include (i) a shackle hole (for example, the shackle hole illustrated in the first embodiment) configured to rotatably attach a rod-like shackle as an element for turning the head and having an input part, (ii) a hinge part located on the side of the head and configured to be connected with the possibility of rotation with the part of the hinge located on the side of the element for rotation (for example, the part of the hinge located on the side of the arcuate element for providing rotation) as a member for turning the head, and the like (for example, a columnar hinge portion located on the side of the head and configured to be inserted into the hinge portion located on the side of the arcuate member to ensure rotation, such as the first hinge member 5a, described given in Japanese Unexamined Patent Application Publication No. 2017-384).

[0090]

In the case where the attachment portion of the head turning member is a staple hole, the staple hole inlet portion may be located anywhere on the cleaning head, and is preferably located on the side surface portion. In the case where the cleaning head has a longitudinal direction and a direction along the short side, the opening portion of the staple hole may be located on the side surface portions (both side surface portions) forming the portions (both end portions) end in the longitudinal direction, and on the side surface parts (both side surface parts) forming parts (both end parts) end in the direction along the short side, and preferably located on the side surface parts (both side surface parts) forming parts (both end parts) end in the longitudinal direction . This is due to considerations related to the ease of use of the cleaning tool.

[0091]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), the rotation axis of the cleaning head, the head rotation member (for example, the staple hole and the hinge part located on the side of the head) and the like are preferably located in the center a side surface portion defined in a predetermined direction extending in the direction of the plane. In the case where the cleaning head has a longitudinal direction and a short side direction, the predetermined direction may be a longitudinal direction or a short side direction, and a rotation axis of the cleaning head, a head rotation element (for example, a hole for a bracket and a hinge part located on side of the head) and the like are preferably located at the center defined in the longitudinal direction or the center defined in the direction along the short side. This is due to considerations related to ease of rotation of the cleaning head and ease of use of the cleaning tool.

[0092]

The weight may be placed anywhere in the first region of the head, and it is preferred that the weight be placed at least at a location remote from the axis of rotation of the head. Since the center of mass of the cleaning head can be effectively removed from the head rotation axis while suppressing the increase in the mass of the cleaning head (the cleaning head is likely to move to a vertical position), the cleaning head has a very good cleaning ability of a vertical surface, a very good cleaning ability of a vertical narrow area, very good ability to switch cleaning surfaces and the like. The weight may be placed to extend in a direction along the axis of rotation of the head, and may be positioned to extend in a direction orthogonal to the axis of rotation of the head.

[0093]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the application of the present disclosure), in the case that the cleaning head is provided with an odd or even number of weights, weights equal to the given odd or even number can be placed so that the weights will traverse a virtual plane centered in the thickness direction and located at the center of the cleaning head defined in the thickness direction. As a result, when the user picks up the cleaning tool including the cleaning head, the cleaning head is likely to be brought to a vertical position in which it extends in a direction extending along the vertical direction. In addition, in the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the application of the present disclosure), in the case where the cleaning head is provided with an even number of weights, weights equal to this even number can be placed symmetrically with respect to the above-described virtual plane centered in the thickness direction. As a result, when the user picks up the cleaning tool including the cleaning head, the cleaning head is likely to be brought to a vertical position in which it extends in a direction extending along the vertical direction.

[0094]

In addition, in the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the application of the present disclosure), in the case where the cleaning head is provided with a weight, the weight can be placed asymmetrically with respect to a virtual plane centered in the thickness direction and located in the center of the cleaning head, as defined in the thickness direction. For example, in the case where the cleaning head is provided with a single weight, the weight can be placed so that it does not cross the virtual plane centered in the thickness direction. As a result, when the user picks up the cleaning tool including the cleaning head, it will be easy to switch the cleaning tool between the horizontal surface cleaning mode and the vertical surface cleaning mode, since the cleaning head is likely to deviate from the vertical direction to the oblique direction.

[0095]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), in the case where the cleaning head is to be cleaned by attaching a cleaning sheet, the cleaning head may be provided with a clamp portion that clamps at least one of one the end part and the other end part of the cleaning sheet and is made with the possibility of its translation into the open position and the closed position. As a result, the end portion of the cleaning sheet clamped by the clamp portion is less likely to be separated from the clamp portion, and the possibility of separation of the cleaning sheet from the cleaning head is reduced. The clamping portion may clamp one of one end portion and the other end portion of the cleaning sheet, and may clamp both end portions, that is, one end portion and the other end portion of the cleaning sheet.

[0096]

The clamp portion is not particularly limited as long as it can clamp the cleaning sheet, and the clamp portion is provided with the first clamp portion and the second clamp portion. Preferably, the first gripping part and the second gripping part are rotatably connected by means of a pivoting end having a rotation axis of the gripping part extending in a direction extending along a predetermined direction (preferably in a direction along the head rotation axis and the longitudinal direction) and connected to being able to be opened and closed by means of an opening and closing end extending in a direction extending along the predetermined direction (preferably in the direction along the axis of rotation of the head and the longitudinal direction). As a result, the end portion of the cleaning sheet clamped by the clamp portion is less likely to be separated from the clamp portion, and the possibility of separation of the cleaning sheet from the cleaning head is reduced.

[0097]

The pivot end and the open/close end can be positioned anywhere on the cleaning head. For example, in the case where the pivoting end (rotation axis of the clamping part) and/or the opening and closing end extend in a direction along the pivoting axis of the head, the pivoting end (rotation axis of the clamping portion) and/or the opening and closing end may be located in a part end in an orthogonal direction orthogonal to the axis of rotation of the head, in the area adjacent to the axis of rotation of the head, or the like. Further, in the case where the pivot end (rotation axis of the clamping portion) and/or the opening and closing end extend in a direction extending along the longitudinal direction of the cleaning head, the pivoting end (rotation axis of the clamping portion) and/or the opening end and the closures may be located in the portion end in the direction along the short side, in the area adjacent to the axis of rotation of the head, or the like.

[0098]

14 and 15 are views for describing a cleaning tool 1 according to another embodiment of the present disclosure (hereinafter, the other embodiment may be referred to as "the second embodiment"). 14 is a perspective view of a cleaning tool 1 according to the second embodiment. Fig. 15 is a sectional view of the cleaning tool 1 taken along the section line XV-XV in Fig. 14.

[0099]

The cleaning tool 1 according to the second embodiment is provided with a clamping portion 123 including a first clamping portion 125 and a second clamping portion 135. The first clamping portion 125 and the second clamping portion 135 are rotatably connected via a pivoting end 145 having an axis RA ₂ of the clamping part turning parallel to the head turning axis RA ₁ (longitudinal direction L), and connected with the possibility of opening and closing through the opening and closing end 147, running parallel to the head turning axis RA ₁ (longitudinal direction L).

[0100]

In the cleaning tool 1 according to the second embodiment, the turning end 145 is located in the second head area 121, and is located at a position closer to the head turning axis RA ₁ in the second head area 121 instead of the other part 151 ending in the S direction along the short side . In addition, the end 147 for opening and closing is located in the area of one part 149, end in the S direction along the short side, in the first area 119 of the head.

[0101]

In the cleaning tool 1 (cleaning head 3) according to the second embodiment, the magnet as weight 153 is placed in the first head area 119 . The head shackle 5 as a head turning member is made of a rod-like member and is configured with a head attachment part 201 and rotatably connected to a shackle hole (not illustrated) as a part for attaching the turning element, with a handle attachment part 203 and connected to the handle 7 of the cleaning tool, and to the spacer part 205, which allows the head attachment part 201 and the handle attachment part 203 to be placed at a distance from each other. The head attachment portion 201, the handle attachment portion 203, and the spacer portion 205 are located in the (not illustrated) virtual plane of the clip, which is one plane.

[0102]

The head attachment part 201 (bracket 5) is provided with a head fixation magnet 181 protruding towards the opposite side of the handle attachment part 203 (bracket 5) in a position opposite the weight 153, and is retractably disposed weight 153. For example, when the user lifts the cleaning tool 1 to clean the vertical narrow area, the first head area 119 including the magnet as the weight 153 moves down, the cleaning head 3 is moved to the vertical position, the weight 153, which is magnet is attracted to the head fixing magnet 181, and the state in which the cleaning head 3 is in the vertical position can be fixed. Therefore, the cleaning tool 1 according to the second embodiment has a very good vertical surface cleaning ability in addition to the horizontal surface cleaning ability. Because the bracket 5 is made of stainless steel, which is a non-magnetic material, the magnet weight 153 does not attract the bracket 5 itself, and the magnet weight 153 is designed to attract only the protruding magnet 181 to fix the head.

[0103]

In addition, in the cleaning tool 1 according to the second embodiment, the first clamp portion 125 is provided with a clamp magnet 183 arranged to attract the magnet constituting the weight 153 at the position of the second clamp portion 135 corresponding to the weight 153. The clamp portion 123 can support closed position by attracting the magnet 183 of the first clamping portion 125 and the weight 153 (magnet) of the second clamping portion 135. In other words, the weight 153 is used not only to place the center of mass in the first head area 119 but also so that the clamp portion 123 maintains the closed position.

[0104]

In addition, in the cleaning tool 1 according to the second embodiment, one end portion (not illustrated) of the cleaning sheet (not illustrated) is held by two first slotted portions 163 located on the first outer surface 127 of the first clamping portion 125. The other end portion (not illustrated) of the cleaning sheet sheet (not illustrated) is held by two second slotted portions 165 located on the second inner surface 139 of the second clamp portion 135. In other words, one end portion (not illustrated) of the cleaning sheet (not illustrated) is held by the first outer surface 127 of the cleaning head 3, and the other the end portion (not illustrated) of the cleaning sheet (not illustrated) is clamped by the clamping portion 123 of the cleaning head 3. Since the cleaning tool 1 according to the second embodiment is the same as the cleaning tool 1 according to the first wa implementation, for other components, their description will be omitted.

[0105]

In the cleaning tool of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), in the case where the cleaning head is configured to hold the cleaning sheet, it is preferable that the cleaning head is provided with a cleaning sheet fixing portion for holding the cleaning sheet. sheet. Examples of the cleaning sheet fixing part include a clip (for example, a clamp part), a slotted part (for example, the first slotted part 163 and the second slotted part 165 illustrated in the first embodiment and the second embodiment), the fastener hook member.

[0111]

The mounting protrusion and the mounting recess forming a pair, respectively, protrudes and is recessed in a predetermined direction. The predetermined direction is preferably a direction forming the direction of the plane of the cleaning head (for example, a longitudinal direction or a direction along the short side), more preferably a direction forming a longitudinal direction of the cleaning head (for example, in or out in the longitudinal direction), and even more preferably inward in longitudinal direction of the cleaning head. As a result, it will be easy to maintain the closed position of the clamping portion.

[0112]

In the cleaning tools of the present disclosure (the cleaning head of the present disclosure, the use of the present disclosure), the cleaning head may be made of various materials, and it is preferable that the outer surface is formed from a soft member and that the inner part is formed from a hard member, harder than the soft element. This is due to both ease of use and cleanability considerations.

[0113]

Examples of the material constituting the soft member include ethylene vinyl acetate (EVA), polyurethane (PU), elastomer, rubber, sponge, various foam materials, fabric (for example, non-woven material such as felt/felt, woven material and knitted material) etc. Examples of the solid body material include acrylonitrile butadiene styrene (ABS) resin, polyolefin (e.g. polyethylene (PE), polypropylene (PP) and the like), polyethylene terephthalate (PET), polyacetal (polyoxymethylene - POM) , polycarbonate (PC), polystyrene (PS), polyamide (PA), polyvinyl chloride (PVC), acrylic resin and composite materials of the above, and metals (eg aluminum) and the like.

[0114]

In the case of the cleaning tool of the present disclosure (application of the present disclosure), the cleaning tool may be provided with a cleaning head, a head turning member, and a cleaning tool handle.

For narrow space clearing reasons, the staple is preferably located in the virtual plane of the staple, which is a single plane.

[0115]

Examples of the rod-shaped element include elements having circular, elliptical, and polygonal cross sections. The shackle preferably has at least a circular cross section of the head attachment portion and preferably has a circular cross section of the entire shackle. This is due to considerations associated with rotation of the cleaning head about the axis of rotation of the head, and considerations associated with the fact that the bracket will be less likely to damage the desired cleaning surface. Examples of the clip material include metals such as magnetic materials (magnetic metals) such as iron (eg galvanized iron), non-magnetic materials (non-magnetic metals) such as stainless steel and aluminum, and the like.

[0116]

In the case of the cleaning tool of the present disclosure (application of the present disclosure), when the cleaning tool is provided with the cleaning head fixing mechanism described later, and the cleaning head fixing mechanism is a pair of magnets or a pair of magnets and a ferromagnet, the clip may be made of ferromagnets. , non-magnetic materials and their combinations and can be provided with magnets.

[0117]

For example, the shackle may be provided with a head attachment part rotatably connected to the shackle hole, a handle attachment part attached to the handle of the cleaning tool, and a spacer to accommodate the head attachment part and the for attaching to the handle, at a distance from each other. The handle attachment part and the spacer part, and the head attachment part and the spacer part may be connected so that they intersect each other, or may be integrally formed so that they are bent.

[0118]

The head attachment portion and the handle attachment portion may be of any length. For example, the head attachment portion may be approximately the same length as the handle attachment portion. As a result, the weight of the bracket and cleaning tool is reduced, and the force applied to the handle of the cleaning tool is likely to be accurately transferred to the cleaning head. In addition, the head attachment portion may be longer than the handle attachment portion. As a result, the force applied to the cleaning tool handle is likely to be transferred to the cleaning head. Further, the head attachment portion may be substantially the same length as the length of the cleaning head, or a length that is longer than the length of the cleaning head. As a result, the force applied to the cleaning tool handle is likely to be transmitted to the entire cleaning head.

[0119]

This is due to considerations related to the ability to clear a narrow space.

[0120]

In the case where the (cleaning head) part for attaching the head turning member is a hinge portion located on the side of the head, the head turning member may be a hinge portion located on the side of the turning member (for example, a hinge portion located on the side element for rotation and made with the possibility of covering the columnar part of the hinge located on the side of the head) and made with the possibility of connecting with the possibility of rotation with the part of the hinge located on the side of the head and provided in the cleaning head (for example, the columnar part of the hinge located on the side of the head and having an axis of rotation of the head).

[0121]

In the case of the cleaning tool of the present disclosure (application of the present disclosure), it is preferable that the cleaning tool further includes a rotation suppression member for suppressing free rotation of the cleaning head about the head rotation axis. As a result, when the cleaning tool is lifted, the cleaning head can be prevented from continuing to swing like a pendulum with the head rotation axis as the axis.

[0122]

Examples of the anti-rotation member include a friction enhancing means (e.g., grease) placed between the (cleaning head) attachment portion of the head turning member and the head turning member [e.g., between the inner surface of the shackle hole and the outer surface of the shackle (e.g., in the head attachment part) and between the hinge part located on the head side and the hinge part located on the side of the pivot element].

By using a friction enhancing means, it is less likely that the effect causing the turn suppression will weaken over time.

[0123]

In addition, examples of the rotation suppression element include a protruding element (for example, a Ο-ring placed on the entire outer periphery of the head attachment part (bracket)) located on the head rotation element (for example, on a part of the outer periphery or on the entire the outer periphery of the part (bracket) for attaching to the head and on the part of the hinge located on the side of the element to ensure rotation) and made with the possibility of providing friction against the part for attaching the element for turning the head (for example, on the inner surface of the opening of the bracket and the part of the hinge located on the head side), and a projecting element located on the part for attaching the element for turning the head (for example, on the inner surface of the hole for the bracket and on the part of the hinge located on the side of the head) and configured to provide friction against the element for turning the head ( for example, on the outer surface of the part (bracket) for attaching to the head vke and part of the hinge located on the side of the bracket), and the like.
