  When the user uses the cleaning tool 1, the user puts his or her hand into the recessed portions 173 arranged on both side surfaces of the cleaning head 3 in the closed configuration in the longitudinal direction L to deploy the cleaning head 3 in the deployed configuration. As shown in FIG. 17, the cleaning head 3 in the expanded form is placed on the cleaning sheet 31 such that the first inner surface 129 and the second inner surface 139 of the holding portion 123 (the first holding portion 125 and the second holding portion 135) are upward. Place it so that it faces.

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

  Next, as shown in FIG. 18, the user inserts one end portion 33 of the cleaning sheet 31 into the first slit portion 163 arranged on each of the two first convex portions 155 of the first holding portion 125. The other end portion 35 of the cleaning sheet 31 is fixed to the second slit portions 165 arranged on the two second convex portions 159 of the second holding portion 135.

Next, the first holding portion 125 and the second holding portion 135 are rotated about the holding portion rotation axis RA ₂ of the rotating end 145, and the fitting projection 169 and the fitting recess 171 are fitted to each other, as shown in FIG. Thus, the cleaning head 3 is in the closed configuration. As a result, the one end 33 of the cleaning sheet 31 is held by the first slits 163 of the two first protrusions 155, and is meshed with the combination of the first protrusion 155 and the second recess 161 ( It is held by the combination of the first concave portion 157 and the second convex portion 159 (two places in total), so that one end 33 of the cleaning sheet 31 is unlikely to come off from the holding portion 123 during use. ..

  Similarly, the other end portion 35 of the cleaning sheet 31 is held by the second slit portions 165 of the two second convex portions 159 and is meshed with the combination of the first convex portion 155 and the second concave portion 161 ( It is held by a combination of the first concave portion 157 and the second convex portion 159 (two places in total), so that the other end portion 35 of the cleaning sheet 31 does not easily come off from the holding portion 123 during use. ..

  When the user cleans a wide space, as shown in FIG. 20, the cleaning tool 1 is in a wide space cleaning mode, and the surface to be cleaned can be cleaned without any particular limitation. The first surface 37 of the cleaning sheet 31 (the surface on the first cleaning surface 113 side of the cleaning head 3) is used for cleaning the surface to be cleaned, and when the first surface 37 becomes dirty, the cleaning head 3 is rotated 180 °. The surface to be cleaned can be cleaned using the second surface 39 of the cleaning sheet (the surface on the second cleaning surface 115 side of the cleaning head 3).

  When the user cleans the narrow space, for example, the vertical narrow space 51 as shown in FIG. 21, the cleaning tool 1 is used in the narrow space cleaning mode, specifically, the cleaning head 3 is used. 3 is rotated so that a plane direction (not shown) of the bracket 3 and an imaginary bracket surface (not shown) of the bracket 5 coincide with each other, and the end portion of the cleaning head 3 in the longitudinal direction L (preferably, the bracket hole 117). The end portion on the side where the opening 117a does not exist) can be put in a narrow space to clean the surface to be cleaned in the narrow space.

  In order to change the cleaning tool 1 from the wide space cleaning mode to the narrow space cleaning mode, the cleaning tool 1 may simply be lifted. When the cleaning tool 1 (cleaning head 3) is lifted, the center of gravity of the cleaning head 3 exists in the first head region 119, and thus the cleaning head 3 easily stands up with the first head region 119 facing downward.

  Further, in the cleaning head 3 of the cleaning tool 1 according to the first embodiment, the rotating end 145 is arranged at the other end 151 of the cleaning head 3 in the lateral direction S of the first head region 119, so that cleaning is performed. When the head 3 is lifted, the cleaning head 3 stands up so that the rotating end 145 faces downward and the opening / closing end 147 faces upward. Therefore, it is easy to clean the corner 53 of the vertically narrow space 51 by using the side surface of the cleaning head 3 on the first head region 119 side (rotating end 145 side), and at that time, the cleaning sheet 31 causes the cleaning head 3 to clean. It becomes difficult to come off.

Further, in the cleaning tool 1, in the state where the cleaning head 3 is arranged such that the plane direction P of the cleaning head 3, the bracket virtual surface IS _B of the bracket 5 and the handle axis HA are parallel (more specifically, they are on the same plane). , The first direction D ₁ extends parallel to the plane direction P. As a result, when the cleaning tool 1 is deformed into the narrow space cleaning mode, the cleaning tool handle 7 includes the connecting rod 301, the first handle portion 307, the second handle portion 309, and the third handle portion 311 which are the second portions. Since the direction D ₂ (thickness direction) is opposed to the thickness direction T of the cleaning head 3, the cleaning tool handle 7 is less likely to be caught in the width direction of the vertically narrow space.

Further, as shown in FIG. 6, in the cleaning tool 1, the connecting rod 301 (cleaning tool handle 7) forming the rotating portion approaches the handle connecting portion 203 of the bracket 5 about the handle rotation axis RA _3. It is rotatable in a proximal direction D _P and a distal direction D _D moving away from the handle connecting portion 203. Further, the first pushing protrusion 513 of the first engaging member 501, the second pushing protrusion 553 of the second engaging member 551, the third pushing protrusion 557 of the third engaging member 555, The fourth pushing protrusion 561 of the fourth engaging member 559 is arranged in the proximal direction D _{P of} the first handle portion 307, the second handle portion 309, the third handle portion 311, and the connecting rod 301, respectively. It is located on the side.

As a result, as shown in FIG. 21, when the cleaning tool 1 is deformed into the narrow space cleaning mode and the cleaning tool handle 7 is tilted in the proximal direction D _P , the cleaning head 3 on the side opposite to the bracket 5 is removed. When the portion is used for cleaning a narrow space, the first pushing protrusion 513, the second pushing protrusion 553, the third pushing protrusion 557, and the fourth pushing protrusion 561 are proximal. Since it is arranged on the direction D _P side (that is, on the bracket 5 side), the first pushing protrusion 513, the second pushing protrusion 553, the third pushing protrusion 557, and the fourth pushing protrusion The projecting portion 561 makes it difficult to damage the surface to be cleaned forming the narrow space in the vertical direction.

  The bracket is, for example, a head connecting portion having a first end portion rotatably connected to the bracket hole, and a handle connecting portion having a second end portion connected to the cleaning tool handle. The head connecting portion and the handle connecting portion may be separated from each other. The handle connecting part and the separating part and the head connecting part and the separating part may be connected so as to intersect with each other, and may be integrated so as to be curved.

  The head connecting portion and the handle connecting portion may have arbitrary lengths. For example, the head connecting portion may have substantially the same length as the handle connecting portion, thereby reducing the weight of the bracket and thus the cleaning tool and accurately applying the force applied to the cleaning tool handle to the cleaning head. It becomes easy to convey to. Further, the head connecting portion may be longer than the handle connecting portion, so that the force applied to the cleaning tool handle can be easily transmitted to the cleaning head. Further, the head connecting portion may have a length substantially the same as that of the cleaning head or a length longer than that of the cleaning head, so that the force applied to the cleaning tool handle is transmitted to the entire cleaning head. It will be easier.

  In the head connecting portion, the handle connecting portion, and the separating portion, at least the head connecting portion and the handle connecting portion are preferably arranged on the virtual plane of the bracket, and the head connecting portion, the handle connecting portion, and the separating portion. However, it is more preferable that they are arranged on the virtual plane of the bracket. This is from the viewpoint of cleanability in a narrow space.

  In the cleaning tool of the present disclosure (use of the present disclosure), when the bracket is arranged on the bracket virtual surface, the cleaning tool causes the cleaning head and the bracket to move in the plane direction of the cleaning head and the bracket virtual surface. Is preferably configured such that it can be held so as to match, and more preferably configured such that it can be fixed (hereinafter, the cleaning tool may be referred to as having a “cleaning head fixing mechanism”). preferable. As a result, the cleaning tool has excellent cleanability in a narrow space.

  Examples of the cleaning head fixing mechanism include a pair of magnets, a pair of magnets and a ferromagnetic material (for example, iron, cobalt, nickel), a pair of fitting portions, and the like. As an example in which the cleaning head fixing mechanism is a pair of magnets, a magnet arranged on a bracket (for example, a head connecting portion, a handle connecting portion, and / or a separating portion) and a magnet arranged on the bracket of the cleaning head are included. Embodiments including magnets arranged in corresponding positions are included. The same applies to an example in which the cleaning head fixing mechanism is a pair of magnets and a ferromagnetic material. Examples of the cleaning head fixing mechanism that is a pair of fitting portions include a bracket and a groove portion that is formed in the cleaning head and that is formed so as to fit with the bracket.

  In the cleaning tool of the present disclosure (the cleaning head of the present disclosure), the cleaning tool is arranged so that the plane direction of the cleaning head and the handle axis of the handle for the cleaning tool are parallel to each other. It is preferable that the cleaning tool handle is arranged so that one direction extends in a direction along the plane direction of the cleaning head. As a result, when the cleaning head is set up to clean the narrow space, the thin second direction of the cleaning tool handle faces the thickness direction of the cleaning head. The handle is less likely to get caught in the width direction of the narrow space.

  In the cleaning tool of the present disclosure (the cleaning head of the present disclosure), the handle for the cleaning tool includes a rotating portion that is rotatably connected to the second end of the handle connecting portion, and the rotating portion has a virtual bracket surface. When the cleaning tool handle has a rotation axis in a direction perpendicular to the handlebar and is rotatable in a proximal direction toward the handle connection portion of the bracket and a distal direction away from the handle connection portion of the bracket, The sweeper handle is connected to the second end of the handle connecting portion of the bracket so that the sweeper handle has the pushing protrusion on the proximal direction side. Is preferably provided. Thereby, in the above cleaning tool, when the cleaning head is erected and the handle for the cleaning tool is tilted in the proximal direction, when the portion of the cleaning head opposite to the bracket is used for cleaning the narrow space, Since the pushing protrusion is arranged on the proximal direction side (that is, the bracket side), the pushing protrusion is unlikely to damage the surface to be cleaned that forms the narrow space.

  In the cleaning tool of the present disclosure (use of the present disclosure), the cleaning tool is a so-called one-handed cleaning tool (that is, the cleaning head is connected to the bracket through the bracket hole in only one place). It may be provided, and may be a so-called two-handed cleaning tool (that is, the cleaning head is connected to the bracket through the bracket holes at a plurality of locations (preferably at two locations)).

  By holding the cleaning tool with one hand, as shown in FIG. 21, it becomes easier to clean the narrow space by using the end portion of the cleaning head where the bracket is not present. Further, by holding the cleaning tool with both hands, the force of the user is easily transmitted to the cleaning head.

Examples of the cleaning tool that is held by both hands include, for example, a cleaning tool that is connected to a bracket through two bracket holes arranged at two positions on the side surface of the cleaning head.
When the cleaning tool of the present disclosure (use of the present disclosure) has a longitudinal direction and a lateral direction, the two bracket holes are provided on two side surfaces facing each other, which are arranged at both longitudinal ends of the cleaning head. Part or two side parts facing each other, which are arranged at both ends in the lateral direction of the cleaning head, and two side parts facing each other, which are arranged at both longitudinal ends of the cleaning head. Preferably.

  The two bracket holes may be continuously integrated and separated, but preferably have a single head rotation axis.
