Description

本発明は、液剤収容タンクを備える柄と、液剤収容タンクから送られる液剤を吐出する吐出部を備える清掃ヘッドと、柄と清掃ヘッドとを連結する連結部材とを有する湿式清掃具に関する。   The present invention relates to a wet cleaning tool having a handle including a liquid agent storage tank, a cleaning head including a discharge unit that discharges a liquid agent sent from the liquid agent storage tank, and a connecting member that connects the handle and the cleaning head.

例えば液体洗浄剤やワックス等の液剤を、柄に設けた液剤収容タンクから清掃ヘッドに設けた吐出部に供給して、清掃ヘッドに取り付けた清掃シート等を湿った状態に保持しながら、床面等の被清掃面の清掃や仕上げを効率良く行えるようにした湿式清掃具が種々提案されている（例えば、特許文献１参照）。このような湿式清掃具では、液剤収容タンクと吐出部とを連通する可撓性を備えるチューブを介して、液剤収容タンクから吐出部に液剤を供給するようになっている。   For example, a liquid agent such as a liquid cleaning agent or wax is supplied from a liquid agent storage tank provided on the handle to a discharge unit provided on the cleaning head, and the cleaning sheet attached to the cleaning head is kept moist and the floor surface is maintained. Various wet cleaning tools have been proposed that can efficiently clean and finish the surface to be cleaned (see, for example, Patent Document 1). In such a wet cleaning tool, the liquid agent is supplied from the liquid agent storage tank to the discharge portion via a flexible tube that allows the liquid agent storage tank and the discharge portion to communicate with each other.

一方、柄と清掃ヘッドとを連結する連結部材として、清掃ヘッドに対する柄の向きを前後方向での垂直面に沿って変えるだけでなく、前後左右の４方向に変えることを可能にして、３６０°のいずれの方向に対しても回動でき、しかもヘッド角を調整できるようにした、いわゆるユニバーサルジョイントとして知られる２軸型ジョイント部材が種々提案されている（例えば、特許文献１参照）。
特表２００３−５０６１１０号公報 特許第３２３４１４７号公報 On the other hand, as a connecting member for connecting the handle and the cleaning head, it is possible not only to change the orientation of the handle with respect to the cleaning head along the vertical plane in the front-rear direction but also to change the front-rear and left-right directions. Various biaxial joint members known as so-called universal joints that can be rotated in any of these directions and that can adjust the head angle have been proposed (see, for example, Patent Document 1).
Special table 2003-506110 gazette Japanese Patent No. 3234147

例えば２軸型ジョイント部材を介在させて柄と清掃ヘッドとを連結した清掃具に、液剤収容タンクや液材の吐出部を設けて湿式清掃具として用いる場合、柄が清掃ヘッドに対して垂直方向及び３６０°の方向に向きを変えることができるため、柄に設けた液剤収容タンクと、清掃ヘッドに設けた吐出部とを連通する例えば可撓性を備えるチューブには、２軸型ジョイント部材による連結部の周囲で捻れたり、伸ばされたり、曲げられたりすることにより、過度の負担がかかり易くなる。   For example, when a cleaning tool in which a handle and a cleaning head are connected via a biaxial joint member is used as a wet cleaning tool by providing a liquid agent storage tank or a liquid material discharge part, the handle is perpendicular to the cleaning head. And the direction can be changed in the direction of 360 °, and therefore, for example, a flexible tube that communicates the liquid agent storage tank provided on the handle and the discharge part provided on the cleaning head is made of a biaxial joint member. An excessive load is easily applied by twisting, stretching, or bending around the connecting portion.

また、特許文献１の湿式清掃具では、ボール及びフォークからなる構造を有するユニバーサルジョインが用いられており、ボールの内部において、可撓性を有するチューブを、フォークを回動可能に支持する連結ピンの周囲に沿って曲折配置することにより、連結ピンを中心にしてフォークを回動させても、チューブに捩れが生じないようになっているが、フォークの回動によって、ボールの内部でチューブには曲折角度の変動や収縮、伸び等を生じることになるため、このような変形時の負担によって、チューブの消耗や破損を生じ易くなる。   Moreover, in the wet cleaning tool of patent document 1, the universal join which has a structure which consists of a ball | bowl and a fork is used, and the connecting pin which supports the tube which has flexibility in the inside of a ball | bowl so that rotation is possible By twisting and arranging along the circumference of the tube, even if the fork is rotated around the connecting pin, the tube does not twist, but the rotation of the fork causes the tube to move inside the ball. Will cause bending angle fluctuations, shrinkage, elongation, and the like, and the tube is likely to be consumed or damaged by such a burden during deformation.

本発明は、液剤収容タンクを備える柄と、吐出部を備える清掃ヘッドとの連結部材による連結部における、液剤の流路の消耗や破損を効果的に回避することのできる湿式清掃具を提供することを目的とする。   The present invention provides a wet cleaning tool capable of effectively avoiding consumption and breakage of a flow path of a liquid agent in a connecting portion formed by a connecting member between a handle including a liquid agent storage tank and a cleaning head including a discharge portion. For the purpose.
