The present invention relates to a cleaning tool, which comprises: a cleaning tool body, which includes a cleaning head and a base body covering one side of the cleaning head and installed; and a handle part, which is installed on the other side of the cleaning head opposite to the one side; the cleaning tool covers the cleaning surface of the base body and is installed with a cleaning sheet, and the cleaning sheet is used to wipe the cleaning object. The cleaning head and the base body of the cleaning tool body have a planar shape having a pair of short side portions and a pair of long side portions on both sides of the pair of short side portions in a top view. The cleaning sheet covering the cleaning surface formed by one side of the substrate is folded back at the short side of the substrate, and the ends are respectively engaged with a pair of engaging parts provided in the end parts of the two sides of the long side direction of the cleaning head, thereby being installed on the cleaning tool body. The engaging parts are composed of the following elements: a plug-in cover sheet, which is overlapped and arranged on the end part of the long side direction of the other side of the cleaning head and can be opened; a magnet, which is provided at either the end part of the long side direction of the other side of the cleaning head or the plug-in cover sheet; and a magnetic body, which is provided at the other of the end part or the plug-in cover sheet and can be magnetically connected to the magnet. By utilizing the magnetic force of the magnet and the magnetic body, the end of the cleaning sheet folded back at the short side of the substrate is clamped between the end portion in the long side direction of the substrate and the insert-type cover sheet, and is detachably fastened.

In the cleaning tools of Patent Documents 1 and 2, the cleaning tool body has a rectangular plane shape that is relatively long in the horizontal direction when viewed from above, and can use the short side direction of the rectangular plane shape as the main cleaning direction to efficiently perform cleaning operations using the cleaning surface that is relatively wide in the horizontal direction of the long side. In addition, the cleaning sheet covering the cleaning surface of the cleaning tool body is folded back at the end along the long side of the cleaning tool body and inserted and engaged with a slit-shaped engaging portion provided in the surface of the cleaning tool body on the opposite side of the cleaning surface, so that it can be detachably mounted on the cleaning tool body.

On the other hand, the cleaning tools of Patent Documents 1 and 2 can efficiently clean the floor of a larger area such as the floor of a living room by using the shorter side of the rectangular plane shape as the main cleaning direction and the wider cleaning surface in the longer side direction, but they are not suitable for cleaning the floor of a small area where objects are located, such as a washroom with a toilet. Therefore, the industry expects to develop a new cleaning tool that is suitable for cleaning objects such as the ground or installations in a small area, and expects to make it easier to load and unload the cleaning sheet for the newly developed cleaning tool.

The present invention relates to a cleaning tool, which can cover the cleaning surface more easily and install the cleaning sheet on the cleaning tool body in a detachable manner, and can efficiently clean the cleaning objects such as the ground or installations in a narrow area.

The cleaning tool 10 of a preferred embodiment of the present invention shown in FIG. 1 covers the cleaning surface 14 of the base 13 of the cleaning tool body 11 and has a disposable cleaning sheet 30 installed in a removable and replaceable manner (see FIG. 6( a) ), and is used in the following operations: for example, the floor or the area where the installation is located in a small area, preferably the floor, wall, door, ceiling, etc. of the washroom, toilet, kitchen, and entrance, or the bottom of a washing machine or the gap between the washing machine and the wall, the top of a refrigerator, etc., to clean the floor or the installation (see FIG. 6( b) ). For example, the area of a bathroom is usually less than one tatami, and the toilet 60 and other facilities become obstacles, making it difficult to move the cleaning tool 10 freely like cleaning the floor of a living room, and further, it is difficult for the operator to work behind the toilet 60. Therefore, it is necessary to extend the cleaning tool body 11 into a smaller space or the space behind the toilet 60 while working. The cleaning tool 10 of this embodiment has the following functions: it can efficiently clean the ground or facilities in a small area through flexible and stable operation; and it can more easily cover the cleaning surface 14 and detachably install the cleaning sheet 30 on the cleaning tool body 11.

In addition, the cleaning tool 10 of the present embodiment comprises: a cleaning tool body 11, which includes a cleaning head 12, and a base 13 which covers one side of the cleaning head 12, i.e., the lower surface, and is installed thereon; and a handle portion 20 which is installed on the other side of the cleaning head 12, i.e., the upper surface, which is opposite to the one side, via a joint portion 40; the cleaning tool 10 has a cleaning sheet 30 installed on a cleaning surface 14 formed by covering one side of the base 13, i.e., the lower surface (see FIG. 6( a)), and is suitable for wiping the floor of a bathroom, for example, as a cleaning object, with the cleaning sheet 30, and is smaller in shape than previous cleaning tools which are suitable for cleaning the floor of a living room, etc. As shown in Fig. 2 and Fig. 3, the cleaning head 12 and the base 13 of the cleaning tool body 11 have a planar shape having a pair of short side portions 12a, 13a and a pair of long side portions 12b, 13b on both sides of the pair of short side portions 12a, 13a in a top view. As shown in Fig. 6(a), the cleaning sheet 30 covering the cleaning surface 14 formed by one side, i.e., the lower surface of the base 13, is mounted on the cleaning tool body 11 by being folded back at the short side portions 12a, 13a of the base 13 and having its ends respectively buckled with a pair of buckling portions 50 provided in the end portions on both sides of the long side direction of the cleaning head 12. As shown in FIG. 2 and FIG. 8(a) and (b), the snap-fit portion 50 is composed of the following elements: a plug-in cover 54, which is overlapped and arranged at the end portion of the other side of the cleaning head 12, i.e., the upper surface side, in the long side direction, and can be opened; a magnet 52, which is provided at either the end portion of the other side of the cleaning head 12, i.e., the upper surface side, in the long side direction or the plug-in cover 54 (in the present embodiment, the end portion of the upper surface side of the cleaning head 12 in the long side direction); and a magnetic body 53, which is provided at the other of the above-mentioned end portion or the plug-in cover 54 (in the present embodiment, the plug-in cover 54), and can be magnetically connected to the magnet 52. By utilizing the magnetic force of the magnet 52 and the magnetic body 53, the end of the cleaning sheet 30 folded back at the short side 13a of the base 13 is clamped between the end portion in the long side direction of the base 13 and the insert cover 54, and is detachably engaged (see FIG. 6(a)).

Furthermore, in the present embodiment, it is preferred that the insertable cover 54 rotates around a rotation axis 54a (see FIG. 8(b) ) disposed in the short side direction away from the short side of the cleaning head 12, thereby being openably overlapped with the end portion in the long side direction of the portion disposed on the other side, i.e., the upper surface side, of the cleaning head 12.

Furthermore, in this embodiment, the magnet 52 and the magnetic body 53 are installed on the back side of the plates while being covered by the plate forming the other side, i.e., the upper surface, of the cleaning head 12 or the plate forming one side, i.e., the lower surface, of the insert cover 54.

Here, in this specification, the direction along the short side portion 12a of the cleaning head 12 is set as the short side direction or the left-right direction (X direction), and the direction along the long side portion 12b is set as the long side direction or the front-back direction (Y direction) for description (refer to Figure 2).

In the present embodiment, as shown in Figs. 1 to 3, the cleaning head 12 constituting the cleaning tool body 11 of the cleaning tool 10 is a plastic flat plate member having a substantially rectangular plane shape, for example, a maximum length of about 50 to 90 mm in the short side direction (X direction) (75 mm in the present embodiment) and a maximum length of about 120 to 160 mm in the long side direction (Y direction) (140 mm in the present embodiment), and is made of, for example, ABS resin (Acrylonitrile Butadiene Styrene). Thus, the cleaning head 12 has a small shape compared to the previous cleaning tools mainly used for cleaning the floor of the living room. A pair of long side portions 12b of the cleaning head 12 has, for example, a contraction portion 12c with a curvature radius of about 200 to 300 mm and curved concavely toward the central side connected to the handle portion 20. In addition, an annular peripheral wall rib 16 is continuously formed in the circumferential direction, protruding from the periphery of the cleaning head 12 to the lower surface side at a height of about 3 to 10 mm. The outer peripheral surface of the corner of the annular peripheral wall rib 16 in the short side portion 12a is formed in an arc shape. Thereby, it is possible to effectively prevent the installed cleaning sheet 30 from being easily damaged when it is folded back at the short side portion 12a.

As shown in FIG. 4 , a reinforcing rib 17 is provided on the lower surface side of the cleaning head 12, spanning a considerable area of the central portion and protruding at a height not exceeding the lower end of the annular peripheral wall rib 16. The reinforcing rib 17 forms a three-dimensional pattern of a specific shape in the central portion of the region surrounded by the annular peripheral wall rib 16, and is used to increase rigidity to cope with the pressing force applied from the handle portion 20 mounted on the central portion of the upper surface side. A coupling rib 18a is provided on the short side portion 12a on both sides of the long side direction (Y direction) of the region surrounded by the annular peripheral wall rib 16, protruding at a height not exceeding the lower end of the annular peripheral wall rib 16. The coupling rib 18a is arranged close to the annular peripheral wall rib 16 and extends in the short side direction (X direction). The short side portion 13 a of the base 13 is joined to the short side portion 12 a of the cleaning head 12 via the joining ribs 18 a.

Furthermore, a circular protrusion 18b is disposed on the lower surface side of the cleaning head 12, and the circular protrusion 18b is adjacent to the central part side of each joint rib 18a where the reinforcing rib 17 is disposed, and is formed by forming the circular insertion recess 51 (refer to FIG. 8(a)) described below on the upper surface side of the cleaning head 12. A locking rib 18c for locking a magnet 52 constituting the following locking portion 50 is protrudingly disposed on the lower surface side of the circular protrusion 18b at a height not exceeding the lower end of the annular peripheral wall rib 16, and the locking rib 18c is disposed concentrically with the circular protrusion 16b and in a disconnected state. Furthermore, a rectangular connecting opening 18d which is relatively long in the transverse direction is extended in the short side direction (X direction) to form an opening. The connecting opening 18d is adjacent to the central part side of each circular protrusion 18b where the reinforcing rib 17 is provided, and is used for the inserting cover 54 constituting the following buckle 50 to be rotatably pinned, and the two side ends of the connecting opening 18d in the short side direction (X direction) are respectively provided with shaft support ribs 18e protrudingly. On the two sides of the short side direction (X direction) across the circular protrusion 16c, arc-shaped auxiliary reinforcing ribs 18f are respectively provided protrudingly.

As shown in FIG. 2 , a head side yoke 19 preferably in a forked shape is provided on the upper surface side of the cleaning head 12 in a manner that the central portion is raised, and the head side yoke 19 forms a joint portion 40 between the cleaning tool body 11 and the handle portion 20 at the central portion. In addition, insert-type cover sheets 54 are respectively installed in a removable manner on both side portions in the long side direction (Y direction) across the head side yoke 19, and the insert-type cover sheets 54 overlap with the end portion in the long side direction (Y direction) of the upper surface of the cleaning head 12, and constitute the following buckle portion 50.

As shown in FIGS. 1 to 3 , the base 13 of the cleaning tool body 11 that constitutes the cleaning tool 10 together with the cleaning head 12 is a deformable thin plate-like member having a substantially rectangular planar shape that is slightly larger than the cleaning head 12, and having a maximum length of about 60 to 100 mm in the short side direction (X direction) (82 mm in the present embodiment), and a maximum length of about 130 to 170 mm in the long side direction (Y direction) (152 mm in the present embodiment), and preferably having a thickness of about 0.5 to 3.0 mm, and being composed of, for example, an elastic body having a hardness of about 90 (the value measured by a type A durometer (Schönbach A) specified in JIS K 6253). Thus, when the base 13 is integrally joined to the cleaning head 12, the peripheral portion is preferably a deformable annular protrusion piece 15 protruding with a protrusion width of 2 to 20 mm, and protrudes further outward than the periphery of the cleaning head 12 while being continuous in the circumferential direction. Regarding the base 13, an edge contraction portion 13e (see FIG. 5) may be provided at the edge of the annular protrusion 15 protruding outward from the long side portion 12b of the cleaning head 12. The edge contraction portion 13e is preferably concavely curved with a larger curvature radius than the contraction portion 12c of the long side portion 12b of the cleaning head 12, for example, a curvature radius of about 300 to 500 mm.

Furthermore, the base 13 is formed into a thin plate shape that is preferably curved in an arc shape with a curvature radius of about 300 to 600 mm in the cross section along the length direction, i.e., the long side direction (Y direction) (see FIG. 3 ). Thus, when the base 13 is integrally joined to the cleaning head 12, it can be installed in a state of protruding from the lower surface of the cleaning head 12 in a curved shape, and can be elastically deformed in a manner of being flattened into a flat shape by the pressing force transmitted to the cleaning head 12 via the handle 20 during wiping. The base 13 preferably maintains a curved shape before being joined to the cleaning head 12.

Furthermore, in the present embodiment, as shown in FIGS. 2 and 3 , in the short side portions 13a on both sides of the other side of the base 13, namely the upper surface side, at positions corresponding to the joining ribs 18a formed protruding toward the lower surface side of the cleaning head 12, base side joining ribs 13c are respectively provided in a state extending in the short side direction (X direction) and being vertically arranged. Furthermore, in the long side portions 13b on both sides of the upper surface side of the base 13, at positions corresponding to the annular peripheral wall ribs 16 of a pair of long side portions 12b having a retracted portion 12c of the cleaning head 12, a pair of plate-like ribs 13d are respectively arranged in a vertically arranged state in a manner that connects the two end portions of a pair of base side joining ribs 13c to each other and forms an annular continuous rib together with the base side joining ribs 13c.

For example, a pair of base side joint ribs 13c of the short side portions 13a on both sides are respectively joined from the outside to a pair of joint ribs 18a provided on the lower surface side of the short side portions 12a on both sides of the cleaning head 12 through an adhesive, thereby enabling the base 13 to be integrally joined to the cleaning head 12. The base side joint ribs 13c can also be joined to the joint ribs 18a by other joining methods such as embedding, clamping, ultrasonic sealing, etc. By respectively connecting a pair of base side connecting ribs 13c to a pair of connecting ribs 18a of the short side portions 12a on both sides of the cleaning head 12, a pair of plate-like ribs 13d of the long side portions 13b on both sides of the base 13 can be configured to slide upward along the inner side surface of the annular peripheral wall ribs 16 of the pair of long side portions 12b of the cleaning head 12. Since a pair of plate-like ribs 13d are provided in the base body so as to slide along the inner side surface of the long side portion of the annular peripheral wall rib 16 of the cleaning head 12, the gap between the long side portion of the annular peripheral wall rib 16 of the cleaning head 12 and the long side portion of the base body 13 bent in the long side direction (Y direction) can be closed, thereby effectively preventing dust or debris from entering the inner side of the cleaning head 12.

In addition, by the pressure transmitted to the cleaning head 12 through the handle portion 20 during wiping, the pair of plate-like ribs 13d slide along the annular peripheral wall ribs 16 of the long side portion 12b of the cleaning head 12, while the base 13 is elastically deformed, thereby flattening the base 13 from the state of protruding in a curved shape from the lower surface of the cleaning head 12 into a flat shape.

Furthermore, in this embodiment, as shown in FIG. 5 , a plurality of planar convex ribs 14a are preferably provided on one surface of the base 13, i.e., the lower surface of the cleaning surface 14, in a state of being dispersed and protruding as a whole. The planar convex ribs 14a are three-dimensional ribs with a preferably flat front end. The planar convex ribs 14a preferably protrude from the lower surface of the base 13 at a height of 0.5 to 5 mm, and further preferably protrude at a height of 1 to 3 mm. Since a plurality of planar convex ribs 14a are dispersedly arranged on the lower surface of the base 13, when the cleaning tool body 11 is slid along the ground with the cleaning sheet 30 sandwiched between the ground to be cleaned and the cleaning surface 14, i.e., the lower surface of the base 13, the cleaning sheet 30 can be pressed to the ground by the plurality of surfaces formed by the finely dispersed planar convex ribs 14a, thereby effectively preventing the cleaning sheet 30 from sliding and being misaligned with respect to the cleaning surface 14, and especially when the cleaning sheet 30 is a water-degradable sheet, it can effectively prevent the cleaning sheet 30 from being easily broken and perforated.

Furthermore, the planar rib 14a preferably has a triangular shape in a top view. In the present embodiment, the planar rib 14a has an equilateral triangular shape. By having a triangular shape, the cleaning blade 30 can be prevented from sliding and being misaligned with respect to the cleaning surface 14 when the cleaning tool body 11 is moved in the short side direction (X direction) to wipe the cleaning object not only in the long side direction (Y direction). The planar rib 14a having an equilateral triangular shape is preferably arranged radially so that the bottom edge portions of the six planar ribs 14a are respectively arranged on the six sides of the imaginary hexagon. Thus, even if the cleaning tool body 11 performs a composite motion in which the long side direction (Y direction) and the short side direction (X direction) are moved, the cleaning blade 30 can be effectively prevented from being misaligned with respect to the cleaning surface 14, thereby enabling reliable cleaning.

In this embodiment, as shown in FIG. 1 , the handle portion 20 constituting the cleaning tool 10 together with the cleaning tool body 11 includes a slender rod-shaped handle body 21 and a grip portion 22 integrally connected and fixed to the upper portion of the handle body 21.

The handle body 21 is assembled as follows: by connecting the pipe member 21a, for example, made of aluminum alloy or ABS resin, in the axial direction through a known connecting portion 23 used as needed, the entire handle portion 20 including the grip portion 22 becomes a length of about 50 to 70 cm suitable for cleaning a small space such as a toilet. A forked handle side yoke 24 composed of a pair of yokes 24a is preferably integrally provided at the lower end of the handle body 21 (handle portion 20). The grip portion 22 is detachably mounted on the upper end of the handle body 21 through a known connecting portion 23a having a structure substantially the same as the connecting portion 23 of the pipe member 21a. The handle portion 20 is rotatably mounted on the central portion of the upper surface side of the cleaning head 12 via a joint portion 40 connected via a rotating connection structure 41 described below.

The grip portion 22 is a molded product made of, for example, ABS resin, and has a roughness and an outer shape that is easy to grasp by hand and is roughly cylindrical. An end cap 25 is mounted on the upper end of the grip portion 22. The end cap 25 is a transparent or translucent elastic member, preferably made of ethylene-vinyl acetate (EVA) resin, which is a relatively soft elastic material with a rubber hardness of 40 to 80 (the value measured by a type A durometer (Schwartz A) specified in JIS K 6253). This can improve the stability of the handle portion 20 when it is placed vertically against a wall, for example, and can improve the operability of the cleaning tool 10 when the grip portion 22 is held for cleaning.

As described above, the joint portion 40 rotatably connecting the cleaning head 12 and the handle portion 20 is connected by connecting the head side yoke 19 protruding from the other surface, i.e., the upper surface, of the cleaning head 12 and the handle side yoke 24 provided at the front end of the handle portion 20 via the rotating connection member 41, so that the handle portion 20 can be connected so that it can rotate relative to the cleaning head 12 in the front-rear direction Y and the left-right direction X (refer to Figures 7 (a), (b)). The rotating connection member 41 has a first rotating shaft portion 41a having a central axis C1 (refer to Figure 8) arranged in the short side direction (X direction), and a second rotating shaft portion 41b having a central axis C2 (refer to Figure 8) arranged in the long side direction (Y direction), and the central axis C1 is orthogonal to the central axis C2. Regarding the joint portion 40, the sliding resistance when rotating around the second rotation axis portion 41b is greater than the sliding resistance when rotating around the first rotation axis portion 41a.

In addition, in the present embodiment, as shown in FIG. 2 , FIG. 7 (a) to (c), and FIG. 8 , the head side yoke 19 is preferably a forked yoke formed by a pair of yoke protrusions 19a, and the handle side yoke 24 is preferably a forked yoke formed by a pair of yokes 24a. Since the head side yoke 19 is a forked yoke formed by a pair of yoke protrusions 19a, and the handle side yoke 24 is a forked yoke formed by a pair of yokes 24a, the sliding friction when the handle 20 is tilted in the short side direction (X direction) or the long side direction (Y direction) can be controlled separately, and the positions of the rotating shaft cores 41a and 41b can be misaligned. Furthermore, in the present embodiment, the height h1 (see FIG. 7(b) ) from the lower surface of the cleaning head 12 to the center axis C1 of the first rotating shaft portion 41a of the rotating connecting member 41 close to the lower surface is preferably 10 to 20 mm, and further preferably 14 to 18 mm (16 mm in the present embodiment).

In this embodiment, the head side yoke 19 has a shape obtained by cutting the center of the raised portion which is provided in a mound-like manner from the center of the upper surface of the cleaning head 12 with a notch width of about 10 to 30 mm. Thus, the head side yoke 19 has a pair of symmetrical yoke protrusions 19a which are arranged at intervals and have a steep surface 19b which is substantially perpendicular to the lower surface of the cleaning head 12 as an opposing surface. As shown in FIG8 , an engagement hole 19c for engaging the first rotary axis 41a of the rotary connection member 41 is formed in the opening of the steep surface 19b of each yoke protrusion 19a. A guide tapered surface 19d is obliquely cut and formed between the engagement hole 19c and the front edge of the steep surface 19b. The guide tapered surface 19d is used to facilitate the operation of strongly pressing the rotation connection member 41 to engage the first rotation axis portion 41a with the engagement hole 19c.

In addition, in the present embodiment, a sliding friction surface 19e having an arc-shaped concave surface is provided at the bottom surface of the spaced portion between the pair of yoke protrusions 19a disposed at a distance. When the rotary connection member 41 is installed between the pair of yoke protrusions 19a in an embedded manner, the cylindrical first rotary axis 41a of the rotary connection member 41 is in close contact with the sliding friction surface 19e, so that as the rotary connection member 41 rotates around the central axis C1 of the rotary connection member 41, sliding resistance is generated by friction. The sliding resistance between the sliding friction surface portion 19e and the first rotating shaft center portion 41a can be easily adjusted, for example, by providing ribs 19f set to a specific width or number on the sliding friction surface portion 19e and adjusting the contact area and gap.

In this embodiment, the handle side yoke 24 is formed into a forked shape by forming a through groove 24b of considerable width in the axial direction from the front end of the handle 20 toward the grip 22 side at the lower end of the handle 20. The pair of yokes 24a are formed in a manner that the front end edge is formed into an arc shape and the outer peripheral surface is formed into a gently curved convex surface, and are arranged on both sides with the through groove 24b interposed therebetween.

In this embodiment, a pair of yokes 24a are respectively formed with insertion fixing holes 24c that cross the through slots 24b and are used to install the rotating pin member 25. A head mounting recess 24d is formed on the outer surface side of one yoke 24a for the head 25b of the rotating pin member 25 to be embedded.

The rotating pin member 25 comprises: a cylindrical pin body 25a, which crosses the through groove 24b and has both ends fixed to the insertion and fixing holes 24c of the pair of yokes 24a, and a head 25b, which is integrally provided at one end of the pin body 25a. In addition, a pin side sliding sleeve 25c is integrally installed on the pin body 25a for increasing the friction force with the circular shaft opening 41e of the second rotating shaft center portion 41b of the rotating connection member 41. Regarding the rotating pin component 25a, when the second rotating axis center portion 41b of the rotating connecting component 41 is inserted into the through groove 24b between a pair of yokes 24a so that the center of its circular axis opening 41e is aligned with the center of the insertion and fixing hole 24c of the yoke 24a, the pin body 25a of the rotating pin component 25 is inserted and fixed at both ends, thereby enabling the lower end of the handle portion 20 to be rotatably connected to the rotating connecting component 41.

In the present embodiment, the rotational connection member 41 disposed between the head-side yoke 19 and the handle-side yoke 24 is, for example, a plastic molded product, and as shown in Figs. 7(a) to (c) and 8, it has a first rotational axis 41a and a second rotational axis 41b whose center axes C1 and C2 are orthogonal to each other in a three-dimensional cross shape. The first rotational axis 41a of the rotational connection member 41 has a cylindrical shape, and engaging protrusions 41c are protrudingly provided from the end surfaces on both sides. The engaging protrusion 41c has a cylindrical shape arranged concentrically with the first rotational axis 41a, and its center axis is the center axis C1 of the first rotational axis 41a.

When the first rotating shaft center portion 41a of the rotating connection member 41 is strongly pressed to the spaced portion between the pair of yoke protrusions 19a of the head side yoke portion 19 for installation, the engaging protrusion 41c is rotatably engaged with the engaging hole 19c formed in the respective steep surface 19b of the pair of yoke protrusions 19a. Thereby, the outer peripheral surface of the first rotating shaft center portion 41a is in a state of close contact with the sliding friction surface portion 19e provided on the bottom surface portion between the pair of yoke protrusions 19a. In addition, a sliding tapered surface 41d formed by oblique cutting is provided on the lower half of each engaging protrusion 41c on the side opposite to the side where the second rotating shaft center portion 41b protrudes. While overlapping the sliding conical surfaces 41d with the guide conical surfaces 19d formed in the steep surface 19b of the yoke protrusion 19a, the rotating connecting structure 41 mounted on the lower end of the handle portion 20 is pressed to the spaced portion between one pair of yoke protrusions 19a of the head side yoke portion 19, thereby making it easier to perform the operation of strongly pressing the rotating connecting structure 41 to engage the first rotating axis portion 41a with the engaging hole 19c.

The second rotating shaft center portion 41b of the rotating connection member 41 is, for example, a thick plate-like portion that is protruding outward from the outer circumference of the first rotating shaft center portion 41a and has a semi-elliptical front shape. A circular shaft opening 41e is formed at the center of the second rotating shaft center portion 19b, and the circular shaft opening 41e is used to align with the insertion fixing hole 24c of the yoke 24a formed on the handle side yoke 24 so that the pin body 25a of the rotating pin member 25 can be inserted. An opening-side sliding sleeve 41f is installed to cover the inner circumference of the circular shaft opening 41e. The opening side sliding sleeve 41f is in close contact with the outer peripheral surface of the pin side sliding sleeve 25c installed in the pin body 25a of the inserted rotating pin member 25, thereby increasing the friction force with the rotating pin member 25. The central axis of the circular shaft opening 41e and the rotating pin member 25 inserted in the circular shaft opening 41e is the central axis C2 of the second rotating shaft center portion 19b.

In the present embodiment, for example, the rotational connection member 41 is rotatably mounted on the handle-side yoke 24 via the rotational pin member 25 in a state where the second rotational axis portion 41b is inserted into the through groove 24b between the pair of yokes 24a. Subsequently, by overlapping the sliding tapered surface 41d of the engaging protrusion 41c of the first rotating shaft center portion 41a with the guide tapered surface 19d of the steep surface 19b of the yoke protrusion 19a, the rotating connecting structure 41 of the handle side yoke portion 24 installed at the lower end of the handle portion 20 is strongly pressed into the spaced portion between a pair of yoke protrusions 19a of the head side yoke portion 19, so that the engaging protrusion 41c can be rotatably engaged with the engaging hole 19c, thereby forming the joint portion 40. Thus, the lower end of the handle 20 is rotatably connected to the central portion of the upper surface of the cleaning head 12, while the outer peripheral surface of the first rotating shaft center portion 41a of the rotating connection member 41 is in close contact with the sliding friction surface portion 19e provided at the bottom surface portion between one of the symmetrical protrusions 19a of the cleaning head 12. In addition, thereby, the handle 20 can be rotated and tilted in the left-right direction (X direction) or the front-back direction (Y direction) from the state where the cleaning head 12 is vertically arranged perpendicular to the cleaning tool body 11, and the handle 20 can also be freely rotated in the circumferential direction with the rotating connection member 41 as the rotation center.

In the present embodiment, the sliding resistance of the joint portion 40 between the cleaning head 12 and the handle portion 20 formed in this way when rotating around the second rotating shaft portion 41b is greater than the sliding resistance when rotating around the first rotating shaft portion 41a. The sliding resistance when rotating around the first rotating shaft portion 41a is obtained by the outer circumferential surface of the first rotating shaft portion 41a and the cleaning head 12. The sliding resistance when the second rotary shaft center portion 41b rotates as the center is generated by the close contact of the sliding sleeve 41f on the opening side covering the inner peripheral surface of the circular shaft opening 41e of the second rotary shaft center portion 41b and the sliding sleeve 25c on the pin body 25a installed on the rotary pin member 25. In this way, the resistance to the inertial force that wants to rotate in the left-right direction (short side direction) X around the second rotary shaft center portion 41b is increased, and the cleaning tool body 11 is prevented from shaking or tilting in the left-right direction X during operation, thereby improving the stability of operation. From this viewpoint, the sliding resistance when rotating around the second rotation axis portion 41b is preferably 1.2 times or more, more preferably 1.5 times or more, and more preferably 10 times or less of the sliding resistance when rotating around the first rotation axis portion 41a.

Here, the sliding resistance when rotating in the left-right direction (short side direction) X with the second rotating shaft 41b as the center is the peak load measured by a push-pull dynamometer when the position 50 mm above the center axis C2 of the second rotating shaft 41b in the handle 20 is pushed from the state where the handle 20 is vertically standing to the cleaning head 12 to about 45 degrees. The sliding resistance when rotating in the left-right direction (short side direction) X with the second rotating shaft 41b as the center is preferably 0.8 to 2.0 N. The sliding resistance when rotating in the front-back direction (longitudinal direction) Y with the first rotating axis 41a as the center is the peak load measured by a dynamometer when the handle 20 is pushed 50 mm above the center axis C1 of the first rotating axis 41a from the state where the handle 20 is vertically standing on the cleaning head 12 to about 45 degrees. The sliding resistance when rotating with the first rotating axis 41a as the center is preferably 0.2 to 1.2 N.

The sliding resistance when rotating around the second rotating axis portion 41b and the sliding resistance when rotating around the first rotating axis portion 41a can be easily set by, for example, adjusting the material and thickness (including diameter) of the opening side sliding sleeve 41f and the pin side sliding sleeve 25c, or adjusting the material and close contact area of the outer peripheral surface of the first rotating axis portion 41a and the sliding friction surface portion 19e.

In this embodiment, the cleaning tool 10 covers the cleaning surface 14 formed by the lower surface of the base 13 of the cleaning tool body 11 and is detachably mounted with a disposable cleaning sheet 30 for cleaning operations. As shown in FIG6 , the cleaning sheet 30 is preferably mounted on the cleaning tool body 11 by folding back at the short sides 12a and 13a of the cleaning head 12 and the base 13 and snapping the end portion to the cleaning head 12 via the snapping portion 50. The cleaning sheet 30 is folded back at the short sides 12a and 13a of the base 13 and the ends are buckled with the cleaning head 12, so that dust or stains can be better collected from the short sides 12a and 13a to the cleaning sheet 30 when cleaning a narrow area.

The cleaning sheet 30 can be made of various known cleaning sheets such as olefin-based ultrafine fiber nonwoven fabrics as a sheet suitable for covering the cleaning surface 14 formed by the lower surface of the base 13 of the cleaning tool body 11 and installed to remove dust or stains. In addition, when used for cleaning the floor of a bathroom, the cleaning sheet 30 is preferably a water-disintegrable sheet, which can be directly flushed away in a flush toilet after wiping the floor.

In the present embodiment, as shown in FIG. 2, FIG. 6(a) and FIG. 8(a) and (b), the snap-fitting portion 50 for snapping the cleaning sheet 30 onto the cleaning head 12 and mounting it on the cleaning tool body 11 comprises the following components: an insertable cover sheet 54, which can be overlapped and arranged on the other side of the cleaning head 12, i.e., the upper surface side, at a preferably lower end in the long side direction (Y direction); A magnet 52 is provided at either the end portion of the cleaning head 12 in the long side direction or the plug-in cover piece 54 (the end portion of the cleaning head 12 in the long side direction in the present embodiment); and a magnetic body 53 is provided at the other of the above-mentioned end portion or the plug-in cover piece 54 (the plug-in cover piece 54 in the present embodiment) and can be magnetically connected to the magnet 52. By engaging the ends of the cleaning sheet 30 folded back at the short sides 12a and 13a of the cleaning head 12 and the base 13 in a manner such that the cleaning sheet 30 is sandwiched between the upper surface of the end portion of the cleaning head 12, which is preferably lower, and the lower surface of the insert-type cover 54, the cleaning sheet 30 can be easily and detachably mounted on the cleaning tool body 11 (see FIG. 6(a)). In addition, by utilizing the magnetic force of the magnet 52 and the magnetic body 53, the cleaning sheet 30 can be more securely sandwiched between the upper surface of the end portion of the cleaning head 12 and the lower surface of the insert-type cover 54 to engage the cleaning sheet 30, and the cover 54 can be opened and closed more smoothly.

In the present embodiment, the insert-type cover 54 is rotatably mounted on the cleaning head 12 by, for example, supporting both ends of the cover 54 on the shaft support ribs 18e provided on both sides of the connecting opening 18d (see FIGS. 3 and 4) formed on the cleaning head 12, and preferably by pinning a flange-shaped rotating base 54b (see FIGS. 8(a) and (b)) formed to be inserted into the connecting opening 18d to a rotating shaft 54a (see FIG. 8(b)) extending and fixed in the short side direction (X direction). That is, the insert-type cover 54 can rotate around the rotating shaft 54a disposed in the short side direction away from the short side portion 12a of the cleaning head 12. In addition, thereby, the insertable cover sheet 54 is openably overlapped and arranged at the end portion of the portion on the upper surface side of the cleaning head 12 in the longitudinal direction (Y direction).

Furthermore, in this embodiment, as shown in FIG8(b), the magnet 52 constituting the locking portion 50 is locked to the locking rib 18c arranged in a concentrically disjointed state with the circular protrusion 18b, and is thus mounted on the lower surface (back side) side of the circular insertion recess 51 (see FIG8(a)) formed on the upper surface side of the cleaning head 12, which is the lower surface of the portion protruding downward as the circular protrusion 18b (see FIG4). In addition, the magnet 52 is mounted on the back side of the plate material in a state covered by the plate material forming the insertion recess 51 on the upper surface of the cleaning head 12.

As shown in FIG8(b), the magnetic body 53 constituting the locking portion 50 is accommodated in the inner area of the circular insertion protrusion 54c provided on the lower surface side of the insert-in type cover sheet 54 corresponding to the position of the insertion concave portion 51 (refer to FIG8(a)) formed on the upper surface side of the cleaning head 12, and is installed in a state covered by the cover 54d that is locked on the insertion protrusion 54c from the outside. In addition, the magnetic body 53 is installed on the back side of the plate in a state covered by the plate of the cover 54d forming the lower surface of the insert-in type cover sheet 54.

Here, the magnetic material is a substance that can be magnetic, meaning that it is attracted to a magnet. The magnetic material is preferably a metal such as iron, nickel, cobalt, etc., which is a ferromagnetic material that is strongly magnetized in the same direction when it is close to a magnet. In addition, it may also be a magnet itself.

In the present embodiment, the cleaning sheet 30 preferably has a rectangular shape, and the rectangular shape has a lateral width wider than the length in the short side direction (X direction) of the base 13 constituting the cleaning tool body 11, and has a longitudinal width wider than the length in the long side direction (Y direction). The cleaning sheet 30 is arranged on the lower surface side of the base 13 with the longitudinal width along the long side direction (Y direction) of the base 13, and when the insert cover 54 is opened as shown in FIG. 8 (a), the portion of the cleaning sheet 30 extending outward from the short side portion 13a of the base 13 in the long side direction (Y direction), i.e., the end portion, is preferably folded back at the cleaning head 12 and the short side portions 12a, 13a of the base 13. Furthermore, after the end of the cleaning sheet 30 folded back at the short side portions 12a and 13a is laid on the lower end portion of the upper surface of the cleaning head 12, as shown in FIG. 8(b), the plug-in cover 54 in the open state is overlapped with the lower end portion of the upper surface of the cleaning head 12 on which the end of the cleaning sheet 30 is laid, thereby making it a closed state. Thus, the insertable cover 54 is preferably arranged with its upper surface in the same plane as the upper surface of the central portion of the base 13, and the magnetic force of the magnet 52 and the magnetic body 53 can be utilized to easily clamp the end of the cleaning sheet 30 between the lower upper surface of the end portion of the cleaning head 12 and the lower surface of the insertable cover 54, and the end of the cleaning sheet 30 can be firmly clamped.

That is, according to the present embodiment, the ends of the cleaning sheet 30 on both sides, which is provided to cover the cleaning surface 14 formed by the lower surface of the base 13, are folded back at the short side portions 12a and 13a of the cleaning head 12 and the base 13, and the magnetic forces of the magnet 52 and the magnetic body 53 are utilized to clamp them between the upper surfaces of the end portions on both sides of the cleaning head 12 and the lower surfaces of the insert-type covers 54 on both sides. By such a simple operation, the cleaning sheet 30 can be easily and stably mounted on the cleaning tool body 11 in a removable manner. In particular, when the cleaning sheet 30 is a water-degradable sheet, the cleaning sheet 30 can be fastened by the magnetic force of the magnet 52 and the magnetic body 53 while being sandwiched between the upper surface of the end portion of the cleaning head 12 and the lower surface of the insert cover 54 with a relatively large area, so as to prevent the end of the cleaning sheet 30 from being damaged.

Furthermore, in the present embodiment, a circular insertion recess 51 with a magnet 52 disposed on the back side is formed at the lower end portion of the upper surface of the base 13, and a circular insertion protrusion 54c with a magnetic body 53 disposed on the back side of the locked cover 54d is formed on the portion of the lower surface of the insertable cover 54 corresponding to the insertion recess 51. Thus, when the insert cover 54 is closed and the end of the cleaning sheet 30 is clamped between the insert cover 54 and the lower end portion of the upper surface of the cleaning head 12, the end of the cleaning sheet 30 is sandwiched between the bottom surface of the insertion recess 51 and the insertion protrusion 54c that is locked with the cover 54d in a manner that it sinks into the bottom surface of the further lower insertion recess 51 and is clamped between the bottom surface and the lower end surface of the cover 54d that is locked with the insertion protrusion 54c. Furthermore, thereby, the end of the cleaning sheet 30 can be effectively prevented from being misaligned between the upper surface of the end portion of the clamped base 13 and the lower surface of the insert cover 54, so that the cleaning sheet 30 can be installed on the cleaning tool body 11 in a more stable state.

In this embodiment, the magnet 52 and the magnetic body 53 are arranged on the back side of the insertion recess 51 of the cleaning head 12 and the back side of the cover 54d that is locked on the insertion protrusion 54c of the insert cover 54, and are installed on the plate forming the upper surface of the cleaning head 12 or the plate forming the lower surface of the insert cover 54. Therefore, when the slide-in cover 54 is opened or closed to load and unload the cleaning sheet 30, the magnet 52 and the magnetic body 53 can be effectively prevented from falling off from the cleaning head 12. In addition, especially when the cleaning sheet 30 contains cleaning chemicals, the magnet 52 and the magnetic body 53 can be effectively prevented from contacting with the chemicals and deteriorating.

As shown in FIG. 6( a ), the cleaning sheet 30 mounted on the cleaning tool body 11 as described above is preferably mounted on the cleaning tool body 11 in a removable and replaceable manner so that the cleaning sheet 30 extends outwardly from the cleaning head 12 and the long side portions 12 b and 13 b of the base 13 in the lateral direction for cleaning operations. The cleaning sheet 30 used for cleaning operations and, for example, sufficiently attached with dust or stains, is manually operated to resist the magnetic force and rotate and open the insertable cover 54, thereby releasing the clamped state of the end portion, thereby preferably being removed from the cleaning tool body 11 without manual contact, for example, it can be directly flushed away in a flush toilet and discarded.

Furthermore, according to the cleaning tool 10 of this embodiment having the above-mentioned structure, the cleaning surface 14 can be covered more easily and the cleaning sheet 30 can be detachably mounted on the cleaning tool body 11, and the cleaning operation can be easily performed with the long side direction (Y direction) as the main cleaning direction, thereby efficiently cleaning the floor or the area where the installation is located in a small area, such as the floor and installations in the bathroom.

That is, according to the present embodiment, the cleaning tool 10 is preferably small in shape compared to the conventional cleaning tools mainly used for cleaning the floor of the living room, and the cleaning head 12 and the base 13 of the cleaning tool body 11 have a pair of short side portions 12a, 13a and a pair of long side portions 12a, 13a on both sides of the pair of short side portions 12a, 13a in a top view. The planar shape of the parts 12b, 13b is shown in Figure 6(a). The cleaning sheet 30 covering the cleaning surface 14 formed by the lower surface of one side of the base 13 is folded back at the short side parts 12a, 13a of the base 13, and the ends are respectively engaged with a pair of engaging parts 50 provided in the end parts on both sides of the long side direction of the cleaning head 12, and is installed on the cleaning tool body 11. Furthermore, the snap-fitting portion 50 includes a slide-in cover 54, a magnet 52, and a magnetic body 53 which are overlapped and arranged at the end portion of the upper surface side of the cleaning head 12. By utilizing the magnetic force of the magnet 52 and the magnetic body 53, the end portion of the cleaning sheet 30 folded back at the short side portion 13a of the base 13 is clamped between the end portion in the long side direction of the base 13 and the slide-in cover 54, and is snap-fitted in a detachable manner.

In this way, the cleaning operator opens and closes the slide-in cover 54 and utilizes the magnetic force of the magnet 52 and the magnetic body 53 to clamp the end of the cleaning sheet 30 folded back at the short side 13a of the base 13 between the end portion in the long side direction of the base 13 and the slide-in cover 54 and snap it into place, thereby easily covering the cleaning surface 14 and detachably mounting the cleaning sheet 30 on the cleaning tool body 11. The cleaning sheet 30 that is sufficiently covered with dust or stains resists the magnetic force and causes the slide-in cover 54 to rotate and open, thereby releasing the clamped state of the end portion, thereby being able to be easily removed from the cleaning tool body 11, preferably without touching it with hands. For example, when the cleaning sheet 30 is a water-degradable sheet, it can be directly flushed away in the flush toilet 60 and discarded. Furthermore, this can effectively avoid the situation in which the end of the folded cleaning sheet 30 is inserted and fastened to the slit-shaped fastening portion, as in the previous method, the cleaning sheet is easily damaged during insertion or removal, or the damaged sheet enters the interior of the slit, or the fingers are easily caught in the slit during loading and unloading operations.

Moreover, the operator of the cleaning operation sets the long side direction Y as the main cleaning direction, so that the pressure can be applied from the handle portion 20 to the cleaning surface 14, which is preferably formed by the lower surface of the base 13 protruding in a curved shape, so that the cleaning surface can be easily deformed. Therefore, for example, the cleaning tool body 11 can be moved back and forth in the long side direction Y, and the cleaning surface 14, which is preferably curved, can be elastically deformed well. Therefore, for the cleaning surface 14 covered by the cleaning sheet 30, dust or stains can be easily collected from the peripheral portion to the inside, and dust or stains can be efficiently attached to the entire cleaning sheet 30, thereby cleaning the cleaning object. Furthermore, when the cleaning tool body 11 is moved in the long side direction by setting the long side direction as the main cleaning direction, the width of the short side portion 12a of the cleaning tool body 11 becomes narrower, and because of its small shape, it can efficiently clean the ground in a small area or the ground where objects are located.

Furthermore, according to the present embodiment, it is preferred that a pair of long side portions 12b of the cleaning head 12 have a retracted portion 12c that is concavely curved toward the central side where the handle portion 20 is installed. Therefore, as shown in FIG6(b), the concavely curved retracted portion 12c is moved along the side of an installation such as a toilet 60, while the cleaning tool body 11 is flexibly and smoothly rotated. For example, circular wiping can be performed without changing hands to hold the handle portion 20, and the cleaning tool body 11 can be easily extended to the floor of the space behind the toilet 60, thereby enabling more efficient cleaning of the floor of a small area or the floor of an area where an installation is located. From the same viewpoint, for the base body 13, it is also preferred that an edge contraction portion 13e is provided at the edge of the annular protruding piece 15 that protrudes outward from the long side portion 13b (see FIG. 5).

Furthermore, according to the present embodiment, the base 13 preferably has a planar shape that is larger than the cleaning head 12, and the peripheral portion of the base 13 is a deformable annular protrusion 15 that continuously protrudes outward from the periphery of the cleaning head 12 in the circumferential direction. Therefore, while the annular protrusion 15 is deformable, the peripheral portion of the base 13 can be easily brought into close contact with the peripheral surface of the surrounding walls or installations, for example, so as to thoroughly clean corners such as recessed portions or gaps at the interface between the peripheral surface of the surrounding walls or installations and the ground, which are prone to dust or paper scraps.

Furthermore, in the present embodiment, the cleaning sheet 30 is preferably detachably mounted on the cleaning tool body 11 in a state where the side in the lateral width direction extends further outward than the long sides 12b, 13b of the cleaning head 12 and the base 13, and is used in the cleaning operation. Therefore, the portion extending further outward than the long sides 12b, 13b can more efficiently and thoroughly clean the corners such as the concave parts or gaps at the junction of the surrounding walls or the peripheral surfaces of the installations and the ground, which are prone to dust or paper scraps accumulation.

Furthermore, the present invention is not limited to the above-mentioned embodiments, and various modifications may be made. For example, the insert cover does not have to be arranged on the end portion of the length direction of the cleaning head in an openable overlapping manner by rotating around a rotation axis arranged in the short side direction, and may also be arranged to be removable. The magnet and the magnetic body do not have to be installed on the cleaning head and the insert cover as independent components, for example, the insert cover itself may also be a magnetic body. The base does not have to be formed into a thin plate with an arc-shaped cross-section along the length direction, and may also be formed into a flat shape. In addition to the floor of a small area such as a bathroom or the floor of an area where objects are located, the cleaning tool of the present invention can also be used to clean walls, windows or ceilings, etc., and can also be used to clean larger areas such as living rooms. [Industrial Applicability]

According to the cleaning tool of the present invention, the cleaning surface can be covered more easily and the cleaning sheet can be detachably mounted on the cleaning tool body, and the cleaning operation of the cleaning object such as the ground or the installation in the area where the installation is located in a narrow area can be efficiently performed.
