Further, the second longitudinal side surface 17 is a second longitudinal side surface from the first short side surface 19 with the head rotation axis HA (to be exact, a plane defined by the head rotation axis HA and the thickness direction T) as a boundary. It is divided into one portion 18a and a second longitudinal side surface second portion 18b from the second lateral side surface 21.
The cleaning head 3 has two cleaning sheet mounting portions 81 (specifically, slit portions) for fixing the cleaning sheet 91 to the cleaning head 3 on the first cleaning surface CS 1 .
　ヘッド回転部材７は、円柱状の棒状部材を、矩形に折り曲げ、連結することにより形成されている。ヘッド回転部材７は、第１長手側面１５の第１開口部２３と、第２長手側面１７の第２開口部２５とを介して、ヘッド回転部材連結部５に回転可能に連結されており、それにより、清掃ヘッド３が、ヘッド回転軸ＨＡを中心に回転することができる。 The head rotating member 7 is formed by bending a cylindrical rod-shaped member into a rectangular shape and connecting them. The head rotating member 7 is rotatably connected to the head rotating member connecting portion 5 via the first opening 23 of the first longitudinal side surface 15 and the second opening 25 of the second longitudinal side surface 17. As a result, the cleaning head 3 can rotate about the head rotation axis HA.
　清掃具用柄９の柄回転部材１３は、柄本体部１１を、ヘッド回転部材７に対して回転可能にするための部材であり、ヘッド回転部材７に回転可能に連結されている。
　具体的には、柄回転部材１３は、第１部材１３ａと、第２部材１３ｂと、連結部材１３ｃ（具体的には、リベット）とから構成されている。第１部材１３ａは、ヘッド回転部材７の円柱状部分の周面を覆っている。第２部材１３ｂは、連結部材１３ｃを介して第１部材１３ａに連結されているとともに、連結部材１３ｃを中心に、ヘッド回転部材７に近づくように回転可能である。ヘッド回転部材７及び柄回転部材１３のそれぞれの構造は公知であるため、説明を省略する。 The handle rotating member 13 of the cleaning tool handle 9 is a member for making the handle main body 11 rotatable with respect to the head rotating member 7, and is rotatably connected to the head rotating member 7.
Specifically, the handle rotating member 13 is composed of a first member 13a, a second member 13b, and a connecting member 13c (specifically, a rivet). The first member 13a covers the peripheral surface of the columnar portion of the head rotating member 7. The second member 13b is connected to the first member 13a via the connecting member 13c, and is rotatable around the connecting member 13c so as to approach the head rotating member 7. Since the structures of the head rotating member 7 and the handle rotating member 13 are known, the description thereof will be omitted.
　清掃具用柄９の柄本体部１１は、柄回転部材１３に連結されている第１柄部分３１と、第２柄部分３３と、第３柄部分３５と、把持部３９を備える第４柄部分３７とを順に備えている。 The handle main body portion 11 of the handle 9 for cleaning tools includes a first handle portion 31, a second handle portion 33, a third handle portion 35, and a grip portion 39 connected to a handle rotating member 13. Part 37 and the like are provided in order.
　清掃具用柄９は、柄回転部材１３と、第１柄部分３１とを連結及び開放するための押込部４１を備えている。押込部４１は、清掃具用柄９の軸線ＡＬと交差する方向、具体的には、軸線ＡＬと直交する方向に突出している。より具体的には、押込部４１は、清掃具用柄９を短手方向Ｓと平行になるように倒した際に、平面方向Ｐ、具体的には、長手方向Ｌと平行に突出するように配置されている。それにより、狭空間を清掃する際に、押込部４１が、狭空間の天面部及び底面部に接触しにくくなる。
　なお、押込部４１の構造自体は公知であることから、説明を省略する。 The cleaning tool handle 9 includes a push-in portion 41 for connecting and opening the handle rotating member 13 and the first handle portion 31. The pushing portion 41 projects in a direction intersecting the axis AL of the cleaning tool handle 9, specifically, in a direction orthogonal to the axis AL. More specifically, the push-in portion 41 projects so as to project in the plane direction P, specifically, in the longitudinal direction L when the cleaning tool handle 9 is tilted so as to be parallel to the lateral direction S. Is located in. As a result, when cleaning the narrow space, the pushing portion 41 is less likely to come into contact with the top surface portion and the bottom surface portion of the narrow space.
Since the structure of the push-in portion 41 itself is known, the description thereof will be omitted.
　また、柄本体部１１は、第１柄部分３１及び第２柄部分３３を連結及び開放するための本体第１押込部４３と、第２柄部分３３及び第３柄部分３５を連結及び開放するための本体第２押込部４５と、第３柄部分３５及び第４柄部分３７を連結及び開放するための本体第３押込部４７とを備えている。 Further, the handle main body portion 11 connects and opens the main body first pushing portion 43 for connecting and opening the first handle portion 31 and the second handle portion 33, and the second handle portion 33 and the third handle portion 35. The main body second pushing portion 45 for connecting and opening the main body second pushing portion 45 and the main body third pushing portion 47 for connecting and opening the third handle portion 35 and the fourth handle portion 37 are provided.
　本体第１押込部４３～本体第３押込部４７のそれぞれは、押込部４１と同様に、清掃具用柄９を短手方向Ｓと平行になるように倒した際に、平面方向Ｐ、具体的には、長手方向Ｌと平行に突出するように配置されている。それにより、狭空間を清掃する際に、本体第１押込部４３～本体第３押込部４７のそれぞれが、狭空間の天面部及び底面部に接触しにくくなる。 Each of the main body first pushing portion 43 to the main body third pushing portion 47 has a plane direction P, specifically, when the cleaning tool handle 9 is tilted so as to be parallel to the lateral direction S, similarly to the pushing portion 41. It is arranged so as to project parallel to the longitudinal direction L. As a result, when cleaning the narrow space, each of the main body first pushing portion 43 to the main body third pushing portion 47 is less likely to come into contact with the top surface portion and the bottom surface portion of the narrow space.
　第（Ａ－１）実施形態に従う清掃具１では、清掃ヘッド３が、第１長手側面１５の第１長手側面第１部分１６ａ（具体的には、第１長手側面第１部分１６ａの第１短手側面１９より）に配置された第１突起部５１と、第２長手側面１７の第２長手側面第１部分１８ａ（具体的には、第２長手側面第１部分１８ａの第１短手側面１９より）に配置された第２突起部５３とを備えている。第１突起部５１及び第２突起部５３は、それぞれ、第１長手側面１５（第１長手側面第１部分１６ａ）及び第２長手側面１７（第２長手側面第１部分１８ａ）から、長手方向Ｌに突出している。 In the cleaning tool 1 according to the first (A-1) embodiment, the cleaning head 3 is the first portion 16a of the first longitudinal side surface 15 of the first longitudinal side surface 15 (specifically, the first portion 16a of the first longitudinal side surface first portion 16a). The first protrusion 51 arranged on the short side surface 19) and the first short side of the second longitudinal side surface first portion 18a (specifically, the second longitudinal side surface first portion 18a) of the second longitudinal side surface 17. It is provided with a second protrusion 53 arranged on the side surface 19). The first protrusion 51 and the second protrusion 53 are arranged in the longitudinal direction from the first longitudinal side surface 15 (first longitudinal side surface first portion 16a) and the second longitudinal side surface 17 (second longitudinal side surface first portion 18a), respectively. It protrudes to L.
　また、第１突起部５１及び第２突起部５３のそれぞれは、ヘッド回転部材７（より正確には、ヘッド回転部材７のうち、第１開口部２３及び第２開口部２５に隣接する部分）よりも長手方向Ｌの外方に突出している。それにより、第１突起部５１及び第２突起部５３のそれぞれが、清掃性に優れるとともに、ヘッド回転部材７（より正確には、ヘッド回転部材７のうち、第１開口部２３及び第２開口部２５に隣接する部分）を隅部に接触させにくくなる。 Further, each of the first protrusion 51 and the second protrusion 53 is a head rotating member 7 (more accurately, a portion of the head rotating member 7 adjacent to the first opening 23 and the second opening 25). It protrudes outward in the longitudinal direction L. As a result, each of the first protrusion 51 and the second protrusion 53 is excellent in cleanability, and the head rotating member 7 (more accurately, the first opening 23 and the second opening of the head rotating member 7). It becomes difficult to bring the portion (the portion adjacent to the portion 25) into contact with the corner portion.
　また、第１突起部５１及び第２突起部５３のそれぞれは、第１短手側面１９よりも短手方向Ｓの外方に突出していない。それにより、第１突起部５１及び第２突起部５３のそれぞれが、第１短手側面１９を用いた隅部の清掃を阻害しにくい。 Further, each of the first protrusion 51 and the second protrusion 53 does not protrude outward in the short direction S from the first short side surface 19. As a result, each of the first protrusion 51 and the second protrusion 53 is less likely to prevent cleaning of the corner portion using the first short side surface 19.
　第（Ａ－１）実施形態に従う清掃具１の清掃ヘッド３では、第１長手側面第２部分１６ｂに突起部が配置されておらず、そして第２長手側面第２部分１８ｂに突起部が配置されていない。それにより、第１長手側面第２部分１６ｂ及び第２長手側面第２部分１８ｂが、ヘッド回転部材７に接触せず、清掃ヘッド３が、約３６０°まで回転することができる。 In the cleaning head 3 of the cleaning tool 1 according to the first (A-1) embodiment, the protrusion is not arranged on the first longitudinal side surface second portion 16b, and the protrusion is arranged on the second longitudinal side surface second portion 18b. It has not been. As a result, the first longitudinal side surface second portion 16b and the second longitudinal side surface second portion 18b do not come into contact with the head rotating member 7, and the cleaning head 3 can rotate up to about 360 °.
　清掃具１は、以下の通り使用することができる。
　例えば、清掃ヘッド３を、第２清掃面ＣＳ2を下に向けて、第１突起部５１及び第２突起部５３が清掃シート９１の上に位置するように、清掃シート９１の中央部分の上に配置する。次いで、清掃シート９１の両端部分を、清掃ヘッド３の第１清掃面ＣＳ1に重ね、清掃シート９１の両端部分を、２つの清掃シート取付部８１に固定する。 The cleaning tool 1 can be used as follows.
For example, the cleaning head 3 is placed on the central portion of the cleaning sheet 91 so that the first protrusion 51 and the second protrusion 53 are located on the cleaning sheet 91 with the second cleaning surface CS 2 facing down. Place in. Next, both end portions of the cleaning sheet 91 are overlapped with the first cleaning surface CS 1 of the cleaning head 3, and both end portions of the cleaning sheet 91 are fixed to the two cleaning sheet mounting portions 81.
　床面の隅部、例えば、お互いに直交する２つの壁面及び床面により構成される隅部分を清掃する際には、第１突起部５１又は第２突起部５３を用いて、上記隅部分を清掃することができる。清掃具１では、第１突起部５１及び第２突起部５３のそれぞれが、ヘッド回転部材７よりも長手方向Ｌの外方に突出しているので、第１突起部５１及び第２突起部５３のそれぞれが、ヘッド回転部材７が２つの壁面に接触することを抑制しながら、上記隅部分を清掃することができる。
　なお、清掃具１が、第１突起部５１又は第２突起部５３を有しない場合には、ヘッド回転部材７が２つの壁面のいずれかに接触し、清掃ヘッド３が、上記隅部分に到達しにくくなる。 When cleaning a corner portion of a floor surface, for example, a corner portion composed of two wall surfaces orthogonal to each other and a floor surface, the first protrusion 51 or the second protrusion 53 is used to clean the corner portion. Can be cleaned. In the cleaning tool 1, since each of the first protrusion 51 and the second protrusion 53 protrudes outward in the longitudinal direction L from the head rotating member 7, the first protrusion 51 and the second protrusion 53 Each of them can clean the corner portion while suppressing the head rotating member 7 from coming into contact with the two wall surfaces.

　本開示の清掃具は、清掃ヘッドと、上記清掃ヘッドに回転可能に連結されているヘッド回転部材とを備えているものであれば、特に制限されない。
　本開示の清掃具では、上記清掃ヘッドは、長手方向及び短手方向を含む平面方向と、厚さ方向とを備えている板状の形状を有するとともに、長手方向の両端に配置された、第１長手側面及び第２長手側面を備えている。上記清掃ヘッドは、一方の面を清掃面とするものであってもよく、そして両方の面を清掃面とするものであってもよい。 The cleaning tool of the present disclosure is not particularly limited as long as it includes a cleaning head and a head rotating member rotatably connected to the cleaning head.
In the cleaning tool of the present disclosure, the cleaning head has a plate-like shape having a plane direction including a longitudinal direction and a lateral direction and a thickness direction, and is arranged at both ends in the longitudinal direction. It has one longitudinal side surface and a second longitudinal side surface. The cleaning head may have one surface as a cleaning surface and both surfaces as a cleaning surface.
　上記ヘッド回転部材は、清掃ヘッドを回転させることができるものであれば、特に制限されず、清掃ヘッドの任意の位置、例えば、側面（例えば、第１長手側面、第２長手側面、短手方向の両端に配置された側面、すなわち、第１短手側面、第２短手側面等）、清掃ヘッドの一方の面又は他方の面、板状の形状の切欠部等に配置されうる。
　上記ヘッド回転部材の形状は、特に制限されず、清掃ヘッドの回転の軸であるヘッド回転軸を有することが好ましい。 The head rotating member is not particularly limited as long as it can rotate the cleaning head, and is not particularly limited at any position of the cleaning head, for example, a side surface (for example, a first longitudinal side surface, a second longitudinal side surface, a lateral direction). It can be arranged on the side surfaces arranged at both ends of the cleaning head, that is, the first side surface, the second side surface, etc.), one surface or the other surface of the cleaning head, a plate-shaped notch, or the like.
The shape of the head rotating member is not particularly limited, and it is preferable to have a head rotating shaft which is a rotating shaft of the cleaning head.
　上記清掃具は、清掃具用柄を備えることができ、その場合に、清掃ヘッドと、清掃具用柄とは、ヘッド回転部材を介して、連結されたままであるものであっても、そして連結及び開放可能なものであってもよい。また、清掃ヘッド及び清掃具用柄がヘッド回転部材を介して連結及び開放可能なものである場合に、清掃ヘッド、ヘッド回転部材及び清掃具用柄は、任意の箇所、例えば、（ｉ）清掃ヘッドのヘッド回転部材連結部と、ヘッド回転部材との間、（ｉｉ）ヘッド回転部材と、清掃具用柄の柄回転部との間、（ｉｉｉ）清掃具用柄の柄回転部と、清掃具用柄の柄本体部との間、（ｉｖ）清掃具用柄の柄本体部の間等において連結及び開放可能であることができる。 The cleaning tool may be provided with a cleaning tool handle, in which case the cleaning head and the cleaning tool handle are connected, even if they remain connected via a head rotating member. And may be openable. Further, when the cleaning head and the handle for the cleaning tool can be connected and opened via the head rotating member, the cleaning head, the head rotating member and the handle for the cleaning tool can be cleaned at an arbitrary place, for example, (i). Cleaning between the head rotating member connecting portion of the head and the head rotating member, (ii) between the head rotating member and the handle rotating portion of the cleaning tool handle, and (iii) the handle rotating portion of the cleaning tool handle. It can be connected and opened between the handle main body of the tool handle, (iv) between the handle main body of the cleaning tool handle, and the like.
　本開示の清掃具では、清掃ヘッドは、第１長手側面に、長手方向に突出する突起部を備えている。
　上記突起部は、長手方向に突出していれば、その長さは、特に制限されないが、本開示の清掃具が、ヘッド回転部材連結部の開口部を第１長手側面に備えている場合には、上記突起部は、ヘッド回転部材（より正確には、ヘッド回転部材のうち、開口部に隣接する部分）より、長手方向の外方に突出していることが好ましい。それにより、ヘッド回転部材が、上記突起部による清掃を阻害しにくくなる。
　上記突起部は、短手方向に突出していないことが好ましい。それにより、上記突起部が、清掃ヘッドの短手方向の両端に配置された短手側面を用いて清掃することを阻害しにくくなる。 In the cleaning tool of the present disclosure, the cleaning head is provided with a protrusion protruding in the longitudinal direction on the first longitudinal side surface.
The length of the protrusion is not particularly limited as long as it protrudes in the longitudinal direction, but when the cleaning tool of the present disclosure includes an opening of the head rotating member connecting portion on the first longitudinal side surface. It is preferable that the protrusion protrudes outward in the longitudinal direction from the head rotating member (more accurately, the portion of the head rotating member adjacent to the opening). As a result, the head rotating member is less likely to interfere with cleaning by the protrusions.
It is preferable that the protrusion does not protrude in the lateral direction. As a result, it becomes difficult for the protrusions to prevent the cleaning head from being cleaned by using the short side surfaces arranged at both ends in the short direction.
　上記突起部は、清掃性の観点から、第１長手側面の短手方向の端部に配置されていることが好ましい。
　上記突起部は、第１長手側面に、複数個配置されてもよく、例えば、第１長手側面の短手方向の両端に配置されることができる。 From the viewpoint of cleanability, the protrusions are preferably arranged at the end of the first longitudinal side surface in the lateral direction.
A plurality of the protrusions may be arranged on the first longitudinal side surface, for example, they may be arranged at both ends of the first longitudinal side surface in the lateral direction.
　本開示の清掃具において、清掃ヘッドは、ヘッド回転部材と連結するためのヘッド回転部材連結部を備えており、ヘッド回転部材連結部の形状は、ヘッド回転部材の形状に対応するものであれば、特に制限されない。 In the cleaning tool of the present disclosure, the cleaning head includes a head rotating member connecting portion for connecting to the head rotating member, and the shape of the head rotating member connecting portion corresponds to the shape of the head rotating member. , There are no particular restrictions.
　上記ヘッド回転部材連結部としては、例えば、単一の開口部を有する柱状（例えば、円柱状）の中空部を有するヘッド回転部材連結部、複数の開口部（例えば、２つの開口部）を有する柱状（例えば、円柱状）の中空部を有するヘッド回転部材連結部、柱状（例えば、円柱状）の形状を有するヘッド回転部材連結部等が挙げられる。
　上記ヘッド回転部材連結部は、所定の方向に沿う方向に延びていることが好ましく、そして所定の方向と平行に延びていることがより好ましい。上記所定の方向としては、長手方向、短手方向等が挙げられる。 The head rotating member connecting portion includes, for example, a head rotating member connecting portion having a columnar (for example, columnar) hollow portion having a single opening, and a plurality of openings (for example, two openings). Examples thereof include a head rotating member connecting portion having a columnar (for example, columnar) hollow portion, a head rotating member connecting portion having a columnar (for example, columnar) shape, and the like.
The head rotating member connecting portion preferably extends in a direction along a predetermined direction, and more preferably extends in parallel with a predetermined direction. Examples of the predetermined direction include a longitudinal direction, a lateral direction, and the like.
　上記清掃ヘッドが単一の開口部を有するヘッド回転部材連結部を備えている場合であって、清掃ヘッドの側面が、上記単一の開口部を備えている場合には、第１長手側面は、単一の開口部を備えていないことが好ましく、第２長手側面が、単一の開口部を備えていることがより好ましい。第１長手側面に配置された上記突起部が、ヘッド回転部材と接触しにくくなり、清掃ヘッドの回転が阻害されにくくなるからである。 When the cleaning head includes a head rotating member connecting portion having a single opening and the side surface of the cleaning head has the single opening, the first longitudinal side surface is , It is preferable that it does not have a single opening, and it is more preferable that the second longitudinal side surface has a single opening. This is because the protrusions arranged on the first longitudinal side surface are less likely to come into contact with the head rotating member, and the rotation of the cleaning head is less likely to be hindered.
　上記清掃具において、清掃ヘッドの第２長手側面が、ヘッド回転部材連結部の開口部（単一の開口部、又は複数の開口部の中の１つ）を備えている場合には、第２長手側面を、ヘッド回転軸により、第２長手側面第１部分と、第２長手側面第２部分とに区画した際に、第２長手側面第１部分が、長手方向に突出する追加の突起部を備えていることが好ましく、そしてヘッド回転部材（より正確には、ヘッド回転部材のうち、開口部に隣接する部分）よりも長手方向の外方に突出している追加の突起部を備えていることがより好ましい。それにより、追加の突起部により隅部の清掃性が向上するとともに、ヘッド回転部材（より正確には、ヘッド回転部材のうち、開口部に隣接する部分）が、隅部（例えば、壁面）に接触しにくくなる。 In the above cleaning tool, when the second longitudinal side surface of the cleaning head includes an opening (single opening or one of a plurality of openings) of the head rotating member connecting portion, the second When the longitudinal side surface is divided into a second longitudinal side surface first portion and a second longitudinal side surface second portion by a head rotation axis, the second longitudinal side surface first portion protrudes in the longitudinal direction. It is preferably provided with an additional protrusion that projects outward in the longitudinal direction from the head rotating member (more precisely, the portion of the head rotating member that is adjacent to the opening). Is more preferable. As a result, the cleanability of the corner is improved by the additional protrusion, and the head rotating member (more accurately, the portion of the head rotating member adjacent to the opening) is placed on the corner (for example, the wall surface). It becomes difficult to contact.
　また、上述の場合に、第２長手側面第２部分は、長手方向に突出する突起部を備えていないことが好ましい。それにより、第２長手側面第２部分が、第２長手側面の開口部に連結されているヘッド回転部材と接触しにくくなり、清掃ヘッドの回転角度が大きくなりやすくなる。 Further, in the above case, it is preferable that the second portion of the second longitudinal side surface does not have a protrusion protruding in the longitudinal direction. As a result, the second portion of the second longitudinal side surface is less likely to come into contact with the head rotating member connected to the opening of the second longitudinal side surface, and the rotation angle of the cleaning head is likely to increase.
　上記追加の突起部は、短手方向に突出していないことが好ましい。それにより、清掃ヘッドの短手方向の両端に配置された短手側面を用いた清掃が阻害されにくくなる。
　態様Ａ群に係る清掃具の構成部材は、他の態様群（態様Ｂ群、態様Ｃ群）に記載の清掃具の構成部材と任意に組み合わせることができる。 It is preferable that the additional protrusion does not protrude in the lateral direction. As a result, cleaning using the short side surfaces arranged at both ends of the cleaning head in the short side direction is less likely to be hindered.
The constituent members of the cleaning tool according to the A aspect group can be arbitrarily combined with the constituent members of the cleaning tool described in other aspect groups (Aspect B group, Aspect C group).
