Description

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

従来、床面の清掃を行うための掃除具として、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、ヘッド部と柄部とを接続するためのジョイント部と、を有し、ジョイント部を介して、ヘッド部と柄部とが回動可能に連結されたものが知られている。
このような掃除具は、ヘッド部に対して柄部が、ジョイント部を中心として、上下方向に加えて周方向にも回動可能に形成されており、特にベッドやラックの下等の上下方向に狭い空間を掃除する際には、柄部をヘッド部の上面に対して略平行に倒した状態のままで、これを周方向にスムーズに回転させられることが必要となる。しかしながら、多くの掃除具においては、柄部をヘッド部に対して略平行に倒した状態では、これを周方向にスムーズに回転させることは困難であった。 Conventionally, as a cleaning tool for cleaning the floor surface, a head part to which a cleaning member is attached, a handle part for a user to hold the cleaning tool, and a joint for connecting the head part and the handle part And a head portion and a handle portion that are rotatably connected via a joint portion.
In such a cleaning tool, the handle portion is formed to be rotatable in the circumferential direction in addition to the vertical direction with the joint portion as the center, particularly in the vertical direction such as under the bed or the rack. When cleaning a narrow space, it is necessary to smoothly rotate the handle portion in the circumferential direction while the handle portion is tilted substantially parallel to the upper surface of the head portion. However, in many cleaning tools, it is difficult to smoothly rotate the handle portion in the circumferential direction in a state where the handle portion is tilted substantially parallel to the head portion.

そこで、このような課題に対応するため、ジョイント部のヘッド部側のヨーク部の外面を山形状に形成し、ジョイント部の柄部側のヨーク部が、山形状に形成されたヘッド部側のヨーク部の傾斜部に沿ってこれに乗り上げ、また、滑り降りるように移動することで、スムーズな回転を実現したものが存在している（例えば、特許文献１参照）。 Therefore, in order to cope with such problems, the outer surface of the yoke portion on the head portion side of the joint portion is formed in a mountain shape, and the yoke portion on the handle portion side of the joint portion is formed on the head portion side formed in the mountain shape. There is one that achieves smooth rotation by riding on the inclined portion of the yoke portion and moving so as to slide down (for example, see Patent Document 1).

特開２０１２−７５５９４号公報JP 2012-75594 A

しかし、特許文献１に記載の掃除具においては、柄部をヘッド部に対して平行に倒した状態で周方向に回転させる際には、ヘッド部側のヨーク部の山形状の外面に、柄部側のヨーク部が斜めに接触し、上方へと持ち上げられることとなる。したがって、柄部がヘッド部の長手方向と平行な状態に近づくと、柄部の回転の支点に近い部分が持ち上げられるため、柄部が大きく立ち上がり易い。すなわち、柄部が同じ高さ持ち上げられるとしても、回転の支点に近い位置が持ち上げられる程、持ち上げられる角度は大きくなるため、柄部の回転の支点に極めて近い位置が持ち上げられることとなる特許文献１に記載の発明においては、僅かに持ち上げられたのみでも、柄部が大きく立ち上がってしまうこととなる。したがって、柄部をヘッド部の上面と略平行に倒した状態のままで、周方向に回転させることは困難であった。 However, in the cleaning tool described in Patent Document 1, when the handle is rotated in the circumferential direction in a state where the handle is tilted in parallel with the head, the handle is formed on the outer surface of the mountain shape of the yoke portion on the head portion side. The yoke part on the part side contacts obliquely and is lifted upward. Therefore, when the handle portion approaches a state parallel to the longitudinal direction of the head portion, the portion close to the rotation fulcrum of the handle portion is lifted, so that the handle portion is likely to rise greatly. That is, even if the handle is lifted at the same height, the lifted angle increases as the position closer to the rotation fulcrum is lifted, so the position very close to the rotation fulcrum of the handle is lifted. In the invention described in 1, the handle portion rises greatly even if it is lifted slightly. Therefore, it has been difficult to rotate the handle portion in the circumferential direction with the handle portion tilted substantially parallel to the upper surface of the head portion.

本発明の課題は、柄部をヘッド部の上面と略平行に倒した低い状態のままで、これを周方向にスムーズに回動させることができる掃除具を提供することである。 The subject of this invention is providing the cleaning tool which can rotate this smoothly in the circumferential direction in the low state which fell the handle | steering-piece part substantially parallel to the upper surface of the head part.

（実施形態の効果）
本実施形態によれば、第１ヨーク部３１の第１突起部３１１の側面部３１１２が、ヘッド部１の天面部１１の上面から略垂直に立設するように形成されている。したがって、柄部２を、図７（ａ）に示すＸ軸と平行な状態から、Ｒ方向に回転させていった場合に、柄部２は、図７（ｂ）に示すＹ軸と平行な状態となるまでは、第１突起部３１１に当たることはない。
また、ヘッド部１のＹ軸方向両端部付近には、隆起部１１１が形成されているため、柄部２を、図７（ａ）に示すＸ軸と平行な状態から、Ｒ方向に回転させていった場合に、柄部２は、まず、隆起部１１１によって持ち上げられ、この状態において、第１突起部３１１を乗り越えていくこととなる。
したがって、柄部２は、第１突起部３１１を乗り越える際には、第１突起部３１１に当たる以前に、隆起部１１１によって、回転の支点である柄部２とヘッド部１との接続位置から、ヘッド部１のＹ軸方向の端部付近に形成された隆起部１１１までの距離の分離れた位置が持ち上げられていることとなる。したがって、柄部２は、例えば特許文献１に記載の発明と比較して、回転の支点から離れた位置が持ち上げられることとなるため、柄部２が立ち上がる角度は比較的緩やかとなり、柄部２が大きく立ち上がってしまうことはない。
したがって、柄部２をヘッド部１の上面と略平行に倒した低い状態のままで、これを周方向に回転させることが容易となる。 (Effect of embodiment)
According to the present embodiment, the side surface portion 3112 of the first protrusion 311 of the first yoke portion 31 is formed so as to stand substantially vertically from the upper surface of the top surface portion 11 of the head portion 1. Therefore, when the handle 2 is rotated in the R direction from the state parallel to the X axis shown in FIG. 7A, the handle 2 is parallel to the Y axis shown in FIG. The first protrusion 311 is not hit until the state is reached.
Further, since the raised portions 111 are formed in the vicinity of both ends of the head portion 1 in the Y-axis direction, the handle portion 2 is rotated in the R direction from the state parallel to the X-axis shown in FIG. In that case, the handle portion 2 is first lifted by the raised portion 111, and in this state, the handle portion 2 gets over the first projecting portion 311.
Therefore, when the handle portion 2 gets over the first protrusion portion 311, before it hits the first protrusion portion 311, the raised portion 111 causes the connection portion between the handle portion 2 and the head portion 1, which is a fulcrum of rotation. The position where the distance to the raised portion 111 formed near the end portion in the Y-axis direction of the head portion 1 is lifted. Therefore, compared to the invention described in Patent Document 1, for example, the handle portion 2 is lifted at a position away from the fulcrum of rotation, so that the angle at which the handle portion 2 rises is relatively gradual. Will not stand up greatly.
Therefore, it becomes easy to rotate the handle portion 2 in the circumferential direction while keeping the handle portion 2 in a low state where the handle portion 2 is tilted substantially parallel to the upper surface of the head portion 1.

また、図３に示すように、隆起部１１１は、天面部１１の上面にＸ軸方向全体にわたって形成されており、最も高くなるＸ軸方向中央部に向けて、緩やかに隆起している。したがって、柄部２が回転時に急激に持ち上げられることはなく、隆起部１１１に沿って緩やかに持ち上げられることとなるため、スムーズな回転を実現することができる。 Further, as shown in FIG. 3, the raised portion 111 is formed on the upper surface of the top surface portion 11 over the entire X-axis direction, and gently rises toward the highest central portion in the X-axis direction. Therefore, since the handle | steering-wheel part 2 will not be lifted rapidly at the time of rotation but will be lifted gently along the protruding part 111, smooth rotation is realizable.

また、ヘッド部１の天面部１１のＹ軸方向中央部には、隆起部１１１が形成された両端部と比較して上面が低くなる沈降部１１２が形成され、沈降部１１２に、ジョイント部３を介して柄部２が接続されている。したがって、柄部２の接続位置を低くすることができ、低い状態での柄部２の回転が可能となる。
また、掃除具１００の使用時に最も多用される、図７（ａ）に示す柄部２がヘッド部１の長辺と垂直な方向に倒された状態において、柄部２を低い位置まで下げることが可能となる。これによって、上下方向に狭い空間の清掃が容易となる。 Further, a sinking portion 112 whose upper surface is lower than the both end portions where the raised portions 111 are formed is formed in the central portion of the top surface portion 11 of the head portion 1 in the Y-axis direction. The handle 2 is connected via Therefore, the connection position of the handle 2 can be lowered, and the handle 2 can be rotated in a low state.
In addition, the handle 2 is lowered to a low position when the handle 2 shown in FIG. 7A, which is most frequently used when the cleaning tool 100 is used, is tilted in a direction perpendicular to the long side of the head 1. Is possible. This facilitates cleaning of a narrow space in the vertical direction.

また、柄本体２１が、図３に示すように、下端部において、前後方向の厚みが左右方向の厚みと比較して薄くなるように形成されていることから、図７（ａ）及び（ｂ）に示すように柄部２をＸＹ平面に平行に近い状態に倒した状態において、柄本体２１のヘッド部１と重なる部分の上下方向の厚みが薄くなるため、柄部２を低い状態に倒し易くなり、上下方向に狭い空間の清掃が容易となる。 Further, as shown in FIG. 3, the handle main body 21 is formed so that the thickness in the front-rear direction is thinner than the thickness in the left-right direction at the lower end, as shown in FIGS. ), When the handle 2 is tilted to a state close to parallel to the XY plane, the vertical thickness of the portion of the handle body 21 that overlaps the head 1 is reduced, so that the handle 2 is lowered to a lower state. This facilitates cleaning of a narrow space in the vertical direction.

また、ヘッド部１の天面部１１は、隆起部１１１において、他の部分よりＺ軸方向に厚くなっているため、取付部１３を隆起部１１１上に設けることで、取付部１３の穴を深くすることができる。
これによって、清掃シートＰを深く差し込むことができ、清掃シートＰが外れ難くなる。 Further, since the top surface portion 11 of the head portion 1 is thicker in the Z-axis direction than the other portions in the raised portion 111, the mounting portion 13 is provided on the raised portion 111, so that the hole of the attaching portion 13 is deepened. can do.
Thereby, the cleaning sheet P can be inserted deeply, and the cleaning sheet P is difficult to come off.
