[ form A group ]

The cleaning tool of the present invention will be described in detail below.

Fig. 1 to 4 are views for explaining a cleaning tool 1 according to an embodiment of the present invention (hereinafter referred to as "embodiment (a-1)). Specifically, fig. 1 is a perspective view of the cleaning tool 1. Fig. 2 is an enlarged view of a part of the cleaning head 3 of the cleaning tool 1. Fig. 3 is an enlarged view of a part of the cleaning head 3 with the cleaning tool handle 7 laid down. Fig. 4 is a cross-sectional view of section IV-IV of fig. 3.

The cleaning tool 1 of the (a-1) embodiment includes a cleaning head 3 having a handle coupling portion 5, and a cleaning tool handle 7 having a handle body portion 9 and a head rotation member 11. The head rotating member 11 of the cleaning tool handle 7 is rotatably coupled to the handle coupling portion 5 of the cleaning head 3.

The cleaning head 3 is provided with a slit portion 51 for fixing the cleaning sheet at 4 points in total.

The shank coupling portion 5 has a cylindrical structure extending in the longitudinal direction L. The head rotation member 11 is composed of a1 st member 11a, a2 nd member 11b, and a coupling member 11c (specifically, a rivet). The 1 st member 11a covers the circumferential surface of the columnar shank coupling portion 5 and is rotatable in the circumferential direction of the columnar shank coupling portion 5. The 2 nd member 11b is connected to the 1 st member 11a via a connecting member 11c and is rotatable about the connecting member 11c so as to be close to the axis of the columnar shank coupling portion 5. Since the respective configurations of the shank coupling portion 5 and the head rotation member 11 are well known, the description thereof is omitted.

The cleaning head 3 has a plate-like shape including a plane direction P including the longitudinal direction L and the width direction S and a thickness direction T, and includes a cleaning surface CS and a head rotating member coupling surface HS on the side opposite to the cleaning surface CS.

The cleaning head 3 includes a stem coupling portion 5 and a pair of recessed portions 13 extending in the width direction S from the stem coupling portion 5 and configured to receive the head rotation member 11 on the head rotation member coupling surface HS. The pair of recesses 13 each have a bottom 15.

The pair of recessed portions 13 are each configured to allow the cleaning tool handle 7 to rotate in the planar direction P in a state where the cleaning tool handle 7 is accommodated in the recessed portion 13. Specifically, each of the pair of recessed portions 13 is configured to be widened as it is farther from the stem coupling portion 5 in the plane direction P, and specifically, is configured to be widened as it is farther from the stem coupling portion 5 in the width direction S in the longitudinal direction L. Thus, the cleaning tool handle 7 can be easily rotated in the planar direction P in a state where the cleaning tool handle 7 is accommodated in the recessed portion 13.

Further, the bottom portions 15 of the pair of recessed portions 13 extend parallel to the plane direction P, specifically, the width direction S. Therefore, when the cleaning head 3 is placed in a narrow space, the cleaning tool handle 7 is easily parallel to the plane direction P, and the cleaning tool handle 7 is not easily brought into contact with the top surface portion and the bottom surface portion of the narrow space.

The cleaning surface CS has a cleaning region 27 at a position corresponding to the bottom portion 15 of each of the pair of recessed portions 13 in the thickness direction T. Thus, compared with the case where the cleaning head 3 does not have the cleaning region 27, the force applied by the user to the cleaning tool handle 7 is easily transmitted to the surface to be cleaned via the cleaning region 27 of the cleaning surface CS, and the cleaning performance of the surface to be cleaned is improved.

The thickness direction T is divided into the 1 st direction T in the thickness direction from the cleaning surface CS₁And the 2 nd direction T in the thickness direction from the head rotating member connecting surface HS₂And the thickness direction is the 1 st direction T₁When the cleaning head is set in the height direction (the direction in which the height is high), the coupling portion highest-order portion 21, which is the highest portion of the handle coupling portion 5, is arranged at the same position as the head highest-order portion 23, which is the highest portion of the cleaning head 3 except for the handle coupling portion 5, in the thickness direction T. Thus, when cleaning a narrow space, the handle coupling portion 5 is less likely to contact the top surface portion of the narrow space, and the handle coupling portion 5 is less likely to damage the top surface portion.

In the cleaning tool 1, when the cleaning tool handle 7 is housed in the recessed portion 13, the head rotating member 11 is arranged at the same position as the recessed portion highest portion 25 which is the highest portion of the pair of recessed portions 13 in the thickness direction T. Thus, when cleaning a narrow space, the head rotating member 11 is less likely to contact the top surface portion of the narrow space, and the head rotating member 11 is less likely to damage the top surface portion.

The handle body 9 of the cleaning tool handle 7 includes a1 st handle part 31, a2 nd handle part 33, a3 rd handle part 35, and a4 th handle part 37 having a grip part 39, which are connected to the head rotation member 11 in this order.

The cleaning tool handle 7 has a push-in portion 41, and the push-in portion 41 is used for coupling and releasing the head rotating member 11 and the 1 st handle portion 31. The pushing portion 41 protrudes in a direction intersecting the axis AL of the cleaning tool handle 7, specifically, in a direction orthogonal to the axis AL. More specifically, the pushing-in portion 41 is disposed so that the pushing-in portion 41 protrudes in the plane direction P, specifically, in the direction along the longitudinal direction L when the cleaning tool handle 7 is stored in each of the pair of recessed portions 13. Thus, the pushing portion 41 is less likely to contact the top surface portion and the bottom surface portion of the narrow space when cleaning the narrow space.

Since the structure of the pushing portion 41 is well known, the description thereof is omitted.

Further, the stem body portion 9 includes a main body 1 st push-in portion 43 for coupling and releasing the 1 st and 2

nd stem portions

31 and 33, a main body 2 nd push-in portion 45 for coupling and releasing the 2 nd and 3

rd stem portions

33 and 35, and a main body 3 rd push-in portion 47 for coupling and releasing the 3 rd and 4

th stem portions

35 and 37.

The first to 3 rd main body pushing portions 43 to 47 are arranged to protrude in the planar direction P, specifically, in the direction along the longitudinal direction L when the cleaning tool holder 7 is stored in each of the pair of recessed portions 13, similarly to the pushing portion 41. Thus, when cleaning a narrow space, the main body 1 st push-in portion 43 to the main body 3 rd push-in portion 47 are not easily brought into contact with the top surface portion and the bottom surface portion of the narrow space.

Fig. 5 is a diagram for explaining a cleaning tool 1 according to another embodiment of the present invention (hereinafter referred to as "embodiment (a-2)"), and corresponds to fig. 3 of the cleaning tool 1 according to embodiment (a-1).

In the cleaning tool 1 of the (a-2) embodiment, the cleaning head 3 has the shank coupling portion 5 and the pair of recessed portions 13 for receiving the head rotary member 11 on the head rotary member coupling surface HS.

Unlike the cleaning tool 1 of the (a-1) embodiment, each of the pair of recessed portions 13 is not configured to be widened in the longitudinal direction L as it is separated from the shank coupling portion 5 in the width direction S, but is configured to extend in both the longitudinal direction L and the width direction S and to have a substantially rectangular shape when viewed from the thickness direction T. In the cleaning tool 1 of the (a-2) embodiment, the pair of recessed portions 13 is also configured such that the cleaning tool handle 7 is movable in the planar direction P in a state where the cleaning tool handle 7 is housed in either one of the pair of recessed portions 13.

The cleaning tool 1 of the (a-2) th embodiment is otherwise the same as the cleaning tool 1 of the (a-1) th embodiment, and therefore, the description thereof is omitted.

The cleaning tool of the present invention may include a cleaning head having a handle coupling portion, and a cleaning tool handle having a head rotating member coupled to the handle coupling portion and a handle body portion, and is not particularly limited. The cleaning head and the cleaning tool handle may be connected at all times or may be connected and released. In the case where the cleaning head and the cleaning tool handle can be coupled and released, the cleaning head and the cleaning tool handle can be coupled and released at arbitrary positions, for example, (i) between the handle coupling portion of the cleaning head and the head rotating member of the cleaning tool handle, (ii) between the handle coupling portion of the cleaning head and the rest of the cleaning head, (iii) between the head rotating member of the cleaning tool handle and the handle body portion, and (iv) between the handle body portion of the cleaning tool handle.

In the cleaning tool of the present invention, the cleaning head has a plate-like shape including a plane direction and a thickness direction, and includes a cleaning surface and a head rotating member coupling surface on a side opposite to the cleaning surface, the plane direction including a longitudinal direction and a width direction.

The cleaning head has a handle coupling portion and a recessed portion extending in a predetermined direction from the handle coupling portion and receiving the cleaning tool handle, the recessed portion having a bottom portion.

The handle coupling portion may be disposed at any position on the head rotating member coupling surface of the cleaning head, and is preferably disposed in a range of preferably 30% (excluding 20% of each of both ends in the width direction of the cleaning head), more preferably 25% (excluding 25% of each of both ends in the width direction of the cleaning head), still more preferably 20% (excluding 30% of each of both ends in the width direction of the cleaning head), and still more preferably 15% (excluding 35% of each of both ends in the width direction of the cleaning head). This is because the force applied to the cleaning tool handle is uniformly applied to the cleaning surface of the cleaning head.

The handle coupling portion is preferably disposed in a range from the center of the cleaning head in the longitudinal direction toward both ends of the cleaning head in the longitudinal direction, preferably 30% (excluding 20% of both ends of the cleaning head in the longitudinal direction), more preferably 25% (excluding 25% of both ends of the cleaning head in the longitudinal direction), still more preferably 20% (excluding 30% of both ends of the cleaning head in the longitudinal direction), and still more preferably 15% (excluding 35% of both ends of the cleaning head in the longitudinal direction). This is because the force applied to the cleaning tool handle is uniformly applied to the cleaning surface of the cleaning head.

The direction in which the recessed portion extends, i.e., the predetermined direction, is not particularly limited, and examples thereof include a width direction and a longitudinal direction.

The recessed portion is configured such that the cleaning tool handle is movable in the planar direction in a state where the cleaning tool handle is accommodated in the recessed portion. From this viewpoint, for example, (i) the recessed portion may be configured to be widened in a direction (in a planar direction) orthogonal to the predetermined direction as it is farther from the handle connecting portion in the predetermined direction, and (ii) a length of the recessed portion in the direction (in the planar direction) orthogonal to the predetermined direction may be configured to be larger than a thickness of the cleaning tool handle.

In the recessed portion, the bottom portion preferably extends parallel to the planar direction. Therefore, when the cleaning head is placed in a narrow space, the cleaning tool handle is easily parallel to the plane direction, and the cleaning tool handle is not easily brought into contact with the top surface portion and the bottom surface portion of the narrow space.

The recessed portion may be disposed on one side or both sides of the stem coupling portion in the predetermined direction, and is preferably a pair of recessed portions disposed on both sides of the stem coupling portion in the predetermined direction. Thus, the cleaning tool handle can be laid down to both sides in the width direction of the cleaning tool, and the degree of freedom of cleaning is improved.

Preferably, the head rotating member of the cleaning tool handle is capable of moving (e.g., rotating) the cleaning tool handle in a direction parallel to the recessed portion (parallel to the planar direction) while tilting the cleaning tool handle toward the recessed portion (e.g., rotating around the handle connecting portion), so that the cleaning tool handle can be moved in the planar direction while being accommodated in the recessed portion.

The head rotating member preferably has a planar direction rotating mechanism capable of rotating the cleaning tool handle in the planar direction, so that the cleaning tool handle can be moved parallel to the recessed portion (parallel to the planar direction) in a state where the cleaning tool handle is accommodated in the recessed portion.

The planar rotation mechanism may be the head rotation member 11 (the 1 st member 11a, the 2 nd member 11b, and the coupling member 11c) of the cleaning tool according to the embodiment (a-1).

The planar direction rotating mechanism is preferably disposed at a position overlapping the cleaning head in the thickness direction in a state where the cleaning tool handle is accommodated in the recess. Thus, the handle connecting portion of the cleaning head and the head rotating member of the cleaning tool handle are arranged at a close position in the planar direction, and the cleaning performance of the cleaning tool, particularly the cleaning performance in a narrow space, is improved.

From this viewpoint, the handle coupling portion of the cleaning head and the planar direction rotation mechanism are preferably disposed adjacent to each other.

In the cleaning tool of the present invention, the cleaning surface preferably has a cleaning region at a position corresponding to the bottom of the depression in the thickness direction. Thus, compared with the case where the cleaning head does not have a cleaning region, the force applied by the user to the cleaning tool handle is easily transmitted to the surface to be cleaned via the cleaning region of the cleaning surface, and the cleaning performance of the surface to be cleaned is improved.

In the cleaning tool of the present invention, it is preferable that the highest portion of the handle coupling portion, i.e., the highest portion of the coupling portion, is arranged at the same position as or lower than the highest portion of the head, i.e., the highest portion of the head of the cleaning head, which is the highest portion of the handle coupling portion. Thus, when cleaning a narrow space, the handle connecting portion is less likely to contact the top surface portion of the narrow space, and the handle connecting portion is less likely to damage the top surface portion.

Further, it is preferable that the head rotating member is disposed at the same position as or lower than the highest portion of the recessed portion, which is the highest portion of the recessed portion, in the thickness direction when the cleaning tool holder is accommodated in the recessed portion. Thus, when cleaning a narrow space, the head rotating member is less likely to contact the top surface portion of the narrow space, and the head rotating member is less likely to damage the top surface portion.

Further, it is preferable that the handle body portion is disposed at the same position as or lower than the highest portion of the recessed portion in the thickness direction when the handle body portion is housed in the recessed portion when the cleaning tool handle is housed in the recessed portion. Thus, when cleaning a narrow space, the handle body is less likely to contact the top surface portion of the narrow space, and the handle body is less likely to damage the top surface portion.
