Description

本発明は、掃除具に関する。 The present invention relates to cleaning tools.

従来、床面の清掃を行うための掃除具として、清掃用シート等の清掃用部材が取り付けられるヘッド部と、使用者が掃除具を把持するための柄部と、ヘッド部と柄部を回動可能に連結するジョイント部と、を備えて構成されているものが知られている。
このような掃除具は、清掃用シートが取り付けられるヘッド部の形状等によって清掃の効率性が左右されるため、ヘッド部の構造について種々の工夫が凝らされている。 Conventionally, as a cleaning tool for cleaning a floor surface, there is a head part to which a cleaning member such as a cleaning sheet is attached, a handle part for a user to grip the cleaning tool, and a rotating head part and handle part. and a movably connected joint portion.
Since the efficiency of cleaning of such a cleaning tool depends on the shape of the head portion to which the cleaning sheet is attached, various ideas have been devised for the structure of the head portion.

例えば、ヘッド部を床面に押し付けて移動させることで、ヘッド部の下面のうち、移動方向端部側が床面よりも僅かに浮き上がって清掃用シートと床面との間に空間を生じさせるようになっており、その空間に床面上の塵埃や毛髪などを取り込んで、清掃用シートに付着させて除去すること可能にした掃除具が知られている（例えば、特許文献１参照。）。 For example, by pressing the head portion against the floor surface and moving it, of the lower surface of the head portion, the end portion side in the moving direction is slightly lifted from the floor surface to create a space between the cleaning sheet and the floor surface. A cleaning tool is known in which dust, hair, and the like on the floor surface are taken into the space and adhered to a cleaning sheet for removal (see, for example, Patent Document 1).

特許第６２１９４７５号公報Japanese Patent No. 6219475

しかしながら、上記特許文献１の掃除具の場合、床面上の塵埃や毛髪などを捕集する清掃を好適に行うことはできるが、床面にこびりついた固着汚れをこすり落とす清掃には不向きであった。
これは、ヘッド部の下面を床面に強く押し当てようとしても、その力がヘッド部の下面全体に分散してしまい、ピンポイントに力を掛けることができないことによる。 However, in the case of the cleaning tool disclosed in Patent Literature 1, although it is suitable for cleaning by collecting dust and hair on the floor surface, it is not suitable for cleaning by scraping off fixed stains stuck to the floor surface. Ta.
This is because even if an attempt is made to press the lower surface of the head portion strongly against the floor surface, the force is dispersed over the entire lower surface of the head portion, and pinpoint force cannot be applied.

本発明の目的は、床面を広く拭く清掃と、床面の一部をこする清掃の両方を好適に行うことができる掃除具を提供することである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning tool that can suitably perform both cleaning by wiping a wide floor surface and cleaning by rubbing a part of the floor surface.

It is formed for retraction (see FIGS. 3 and 7(a)).

（短手方向凹状部）
短手方向凹状部１２２は、底面部１２の下面側の短手方向（Ｘ軸方向）の両端部付近に形成された上方に向けて凹状となるように形成された部分である。これによって、掃除具１００の使用時において、ヘッド部１の下面側の短手方向（Ｘ軸方向）の両端部付近は、床面に密着せず、床面との間に間隙が生じることとなる。 (Transverse concave portion)
The width direction recessed portions 122 are portions formed in the vicinity of both end portions in the width direction (X-axis direction) of the lower surface side of the bottom surface portion 12 so as to be concave upward. As a result, when the cleaning tool 100 is used, the vicinity of both ends in the short direction (X-axis direction) of the lower surface of the head portion 1 does not come in close contact with the floor surface, and a gap is generated between them and the floor surface. Become.

短手方向凹状部１２２は、ヘッド部１の短手方向（Ｘ軸方向）の両端部付近の下面側において、床面との間に間隙を生じさせることが可能であれば任意の形状に形成することが可能であるが、ヘッド部１の前側又は後側の端部のＹ軸方向中央部において底面部１２の下面側が最も大きく凹むように形成され、当該部分から離れるにつれて凹みが小さくなり、平面部１２１になだらかに接続されるように形成されていることが望ましい。
短手方向凹状部１２２は、最も凹んだ部分において、上方に０．１ｍｍ～５ｍｍ、より好ましくは０．５ｍｍ～３ｍｍ平面部１２１と比較して凹むように形成される。 The transverse direction concave portions 122 are formed in any shape on the lower surface side near both ends in the transverse direction (X-axis direction) of the head portion 1 as long as it is possible to create a gap with the floor surface. However, the lower surface side of the bottom surface portion 12 is formed so as to be dented the most at the Y-axis direction central portion of the front or rear end of the head portion 1, and the dent becomes smaller as the distance from the portion increases. It is desirable to be formed so as to be gently connected to the flat portion 121 .
The width direction recessed portion 122 is formed so that the most recessed portion is recessed upward by 0.1 mm to 5 mm, more preferably 0.5 mm to 3 mm compared to the flat portion 121 .

底面部１２の下面側に短手方向凹状部１２２が形成されていることによって、掃除具１００をヘッド部１の短手方向（Ｘ軸方向）に動かして床面の清掃を行う際に、床面のごみがヘッド部１の前後の端部に溜まらずに、ヘッド部１の下面に誘い込まれるようになり、ごみの捕集性を向上させることができる。 Since the width direction concave portion 122 is formed on the lower surface side of the bottom surface portion 12, when cleaning the floor surface by moving the cleaning tool 100 in the width direction (X-axis direction) of the head portion 1, the floor surface can be easily cleaned. Dust on the surface is not accumulated at the front and rear end portions of the head portion 1, but is drawn to the lower surface of the head portion 1, thereby improving the dust collection performance.

（長手方向凹状部）
長手方向凹状部１２３は、底面部１２の下面側の長手方向（Ｙ軸方向）の両端部付近に形成された上方に向けて凹状となるように形成された部分である。これによって、掃除具１００の使用時において、ヘッド部１の下面側の長手方向（Ｙ軸方向）の両端部付近は、床面に密着せず、床面との間に間隙が生じることとなる。 (Longitudinal concave portion)
The longitudinal concave portions 123 are portions formed in the vicinity of both ends in the longitudinal direction (Y-axis direction) on the lower surface side of the bottom surface portion 12 so as to be concave upward. As a result, when the cleaning tool 100 is used, the vicinity of both ends in the longitudinal direction (Y-axis direction) on the lower surface side of the head portion 1 does not come into close contact with the floor surface, and a gap is generated between them and the floor surface. .

長手方向凹状部１２３は、ヘッド部１の長手方向（Ｙ軸方向）の両端部付近の下面側において、床面との間に間隙を生じさせることが可能であれば任意の形状に形成することが可能であるが、ヘッド部１の右側又は左側の端部のＸ軸方向中央部において底面部１２の下面側が最も大きく凹むように形成され、当該部分から離れるにつれて凹みが小さくなり、平面部１２１になだらかに接続されるように形成されていることが望ましい。
長手方向凹状部１２３は、最も凹んだ部分において、上方に０．１ｍｍ～５ｍｍ、より好ましくは０．５ｍｍ～３ｍｍ平面部１２１と比較して凹むように形成される。 The longitudinal concave portion 123 may be formed in any shape on the lower surface side near both ends in the longitudinal direction (Y-axis direction) of the head portion 1 as long as it is possible to create a gap between it and the floor surface. However, the lower surface side of the bottom surface portion 12 is formed so as to be dented the most at the center portion in the X-axis direction of the right or left end of the head portion 1, and the dent becomes smaller as the distance from the portion increases, and the flat portion 121 It is desirable to be formed so as to be gently connected to the .
The longitudinal concave portion 123 is formed to be concave upward by 0.1 mm to 5 mm, more preferably 0.5 mm to 3 mm, compared to the flat portion 121 at the most concave portion.

底面部１２の下面側に長手方向凹状部１２３が形成されていることによって、掃除具１００をヘッド部１の長手方向（Ｙ軸方向）に動かして床面の清掃を行う際に、床面のごみがヘッド部１の左右の端部に溜まらずに、ヘッド部１の下面に誘い込まれるようになり、ごみの捕集性を向上させることができる。 Since the longitudinal concave portion 123 is formed on the lower surface side of the bottom surface portion 12, when cleaning the floor surface by moving the cleaning tool 100 in the longitudinal direction (Y-axis direction) of the head portion 1, the floor surface can be Dust is not accumulated at the left and right ends of the head portion 1, but is attracted to the lower surface of the head portion 1, thereby improving dust collection performance.

（線状リブ）
底面部１２下面側の平面部１２１には、図５に示すように、底面視において線状となるように下方に凸となった線状リブ１２４が形成されている。
線状リブ１２４は、全てＹ軸方向に同一の高さを有するように形成され、具体的には、０．１ｍｍ～２ｍｍ、より好ましくは０．２ｍｍ～１ｍｍ下方に向けて突出するように形成される。また、各線状リブは、長さが１ｍｍ～１００ｍｍ、より好ましくは８ｍｍ～８５ｍｍ、幅が０．１ｍｍ～２ｍｍ、より好ましくは０．２ｍｍ～１．２ｍｍの線状に形成される。
線状リブ１２４には、底面視略直線状に形成されたリブや、底面視折線状に形成されたリブや、底面視略菱形を呈する線状に形成されたリブなどがある。なお、線状リブ１２４の形状や配置は、図示した態様には限られない。 (linear rib)
As shown in FIG. 5 , linear ribs 124 are formed on the flat portion 121 on the lower surface side of the bottom surface portion 12 and protrude downward so as to form a linear shape when viewed from the bottom surface.
The linear ribs 124 are all formed to have the same height in the Y-axis direction, and specifically, are formed to protrude downward by 0.1 mm to 2 mm, more preferably 0.2 mm to 1 mm. be done. Further, each linear rib is formed linearly with a length of 1 mm to 100 mm, preferably 8 mm to 85 mm, and a width of 0.1 mm to 2 mm, more preferably 0.2 mm to 1.2 mm.
The linear ribs 124 include ribs that are substantially linear when viewed from the bottom, ribs that are formed in the shape of broken lines when viewed from the bottom, and ribs that are substantially rhomboidal and linear when viewed from the bottom. Note that the shape and arrangement of the linear ribs 124 are not limited to the illustrated embodiment.

（端部リブ）
底面部１２下面側の長手方向（Ｙ軸方向）の両端部付近の下面側には、図５に示すように、Ｘ軸方向の中央部に、Ｙ軸方向に沿って直線状に形成された端部リブ１２５が形成されている。
端部リブ１２５は、平面部１２１から見て、下方向に１ｍｍ～５ｍｍの高さを有するように形成される。１ｍｍより低いと溝の清掃を十分に行うことができなくなり、５ｍｍより高いと床面の平面部の清掃の際に邪魔になる可能性が高くなる。ただし、端部リブ１２５は、Ｚ軸方向に線状リブ１２４よりも高くなるように形成される必要がある。
なお、図５に示すように端部リブ１２５が、長手方向凹状部１２３に重なって形成されている場合においても、端部リブ１２５は、平面部１２１に対して上記の高さを有するように形成される必要がある。
また、端部リブ１２５は、Ｙ軸方向の長さ１０ｍｍ～５０ｍｍ、より好ましくは２０ｍｍ～３０ｍｍ、Ｘ軸方向の幅０．１ｍｍ～３ｍｍ、より好ましくは０．５ｍｍ～１．５ｍｍとなるように形成される。
この端部リブ１２５を床面の溝に入り込ませることで、平坦な床面のみならず、溝の清掃を行うことも可能となる。
なお、端部リブ１２５の外端部は、ヘッド部１の長手方向（Ｙ軸方向）の両端部から、０．５ｍｍ～３ｍｍ、より好ましくは０．８ｍｍ～２ｍｍ右方又は左方へ突出するように形成されている。 (end rib)
As shown in FIG. 5, on the lower surface side near both ends in the longitudinal direction (Y-axis direction) on the lower surface side of the bottom surface portion 12, a linear shape is formed along the Y-axis direction at the center portion in the X-axis direction. End ribs 125 are formed.
The end rib 125 is formed to have a height of 1 mm to 5 mm downward when viewed from the plane portion 121 .

（掃除具の使用態様）
本実施形態の掃除具１００を使用する場合、前述したように、底面部１２の下面側に清掃用シートＰを密着させ、底面部１２の下面側からはみ出した部分の清掃用シートＰを天面部１１の上面側に折り返して取付部１３に押し込むようにして、清掃用シートＰをヘッド部１に取り付ける（図２参照）。 (Mode of use of cleaning tools)
When using the cleaning tool 100 of this embodiment, as described above, the cleaning sheet P is brought into close contact with the lower surface of the bottom surface portion 12, and the portion of the cleaning sheet P protruding from the lower surface of the bottom surface portion 12 is removed from the top surface portion. The cleaning sheet P is attached to the head portion 1 by folding it toward the upper surface side of 11 and pushing it into the attachment portion 13 (see FIG. 2).

そして、図７（ａ）に示すように、伸縮部材４の出没部４１をヘッド部１内に収容した第１の状態においては、清掃用シートＰが底面部１２の下面側に密接しているので、その清掃用シートＰで床面を広く拭く清掃を行い、床面上の塵埃や毛髪などを捕集する清掃を好適に行うことができる。
特に、伸縮部材４の出没部４１がヘッド部１内に収容された第１の状態で、その出没部４１の底面４１１は、ヘッド部１の底面部１２の外面（平面部１２１）と略面一に配置されているので、清掃用シートＰが床面から浮いてしまうようなことはなく、底面部１２の開口１２０部分でも床面を好適に拭くことができる。 As shown in FIG. 7A, in the first state in which the retractable portion 41 of the elastic member 4 is housed in the head portion 1, the cleaning sheet P is in close contact with the lower surface of the bottom surface portion 12. As shown in FIG. Therefore, the cleaning sheet P can be used to clean the floor by wiping it widely, and the cleaning can be suitably performed by collecting dust, hair, etc. on the floor.
In particular, in the first state in which the retractable portion 41 of the elastic member 4 is accommodated in the head portion 1 , the bottom surface 411 of the retractable portion 41 is substantially the same as the outer surface (flat portion 121 ) of the bottom surface portion 12 of the head portion 1 . Since they are arranged in the same position, the cleaning sheet P does not float from the floor surface, and the floor surface can be preferably wiped even at the opening 120 of the bottom surface portion 12.例文帳に追加

一方、図７（ｂ）に示すように、伸縮部材４の出没部４１を底面部１２の開口１２０から突出させた第２の状態においては、清掃用シートＰが出没部４１の底面４１１に密接しているので、その出没部４１の底面４１１を床面に強く押し当てるようにして、その部分の清掃用シートＰで床面の一部をこする清掃を行い、床面にこびりついた固着汚れをこすり落とす清掃を好適に行うことができる。
特に、柄部２はジョイント部３を介して、伸縮部材４における出没部４１に相当する部分に取り付けられているので、掃除具１００を使用する際に柄部２を把持した使用者の力を出没部４１部分に作用させ易くなっており、出没部４１の底面４１１を床面に強く押し当ててピンポイントに力を掛けて擦る清掃をより好適に行うことを可能にしている。 On the other hand, as shown in FIG. 7B, in the second state in which the retractable portion 41 of the elastic member 4 protrudes from the opening 120 of the bottom surface portion 12, the cleaning sheet P is in close contact with the bottom surface 411 of the retractable portion 41. As shown in FIG. Therefore, the bottom surface 411 of the retractable portion 41 is strongly pressed against the floor surface, and the cleaning sheet P of that portion is rubbed on the floor surface to clean the adhered dirt stuck to the floor surface. Cleaning by scraping off can be preferably performed.
In particular, since the handle 2 is attached to a portion of the extensible member 4 corresponding to the retractable part 41 of the elastic member 4 via the joint 3, the force of the user holding the handle 2 when using the cleaning tool 100 is reduced. It is easy to act on the protruding part 41 part, and it is possible to perform more suitable cleaning by pressing the bottom surface 411 of the protruding part 41 strongly against the floor surface and applying force to a pinpoint.

そして、この掃除具１００を使用する際であって、伸縮部材４の出没部４１を底面部１２の開口１２０から突出させる場合は、ヘッド部１の長手方向（Ｙ軸方向）の一端を床面に当接させ、他端を床面より高い段差（段差がない場合は使用者の足の甲など）に乗せるなどして、底面部１２の中央側を浮かせた状態にして、柄部２をヘッド部１側に押し下げるように押圧力を加える。あるいは、使用者が一方の手でヘッド部１を保持した状態で、他方の手で掴んだ柄部２の下端をヘッド部１側に押し込むように押圧力を加える。
こうすることで、伸縮部材４を第２の状態に切り替えて、出没部４１を底面部１２の開口１２０から突出させることができる。 When the cleaning tool 100 is used and the retractable portion 41 of the elastic member 4 is projected from the opening 120 of the bottom surface portion 12, one end of the head portion 1 in the longitudinal direction (Y-axis direction) is placed on the floor surface. , and the other end is placed on a step higher than the floor (if there is no step, such as the instep of the user's foot), so that the center side of the bottom portion 12 is raised, and the handle portion 2 is moved. A pressing force is applied so as to press down on the head portion 1 side. Alternatively, the user holds the head portion 1 with one hand and applies a pressing force so as to push the lower end of the handle portion 2 grasped with the other hand toward the head portion 1 side.
By doing so, the retractable member 4 can be switched to the second state, and the retractable portion 41 can be projected from the opening 120 of the bottom portion 12 .

また、底面部１２の開口１２０から突出されている伸縮部材４の出没部４１をヘッド部１内に収容させる場合は、ヘッド部１の底面部１２側を床面に当接させ、そのヘッド部１の天面部１１を使用者の足で軽く踏むように押さえた状態で、柄部２をヘッド部１側から引き上げるように力を加える。あるいは、使用者が一方の手でヘッド部１を保持した状態で、他方の手で掴んだ柄部２の下端をヘッド部１側から引き上げるように力を加える。
こうすることで、伸縮部材４を第１の状態に切り替えて、出没部４１をヘッド部１内に収容させることができる。 Further, when the retractable portion 41 of the elastic member 4 protruding from the opening 120 of the bottom portion 12 is accommodated in the head portion 1, the bottom portion 12 side of the head portion 1 is brought into contact with the floor surface, and the head portion A force is applied so as to pull up the handle 2 from the side of the head part 1 while lightly pressing the top surface part 11 of 1 with the user's foot. Alternatively, while the user is holding the head portion 1 with one hand, a force is applied to pull up the lower end of the handle portion 2 gripped with the other hand from the side of the head portion 1 .
By doing so, the retractable member 4 can be switched to the first state, and the retractable portion 41 can be housed in the head portion 1 .
