Abstract
Description
第1長尺部材における2つの弾性部材と、第2長尺部材における2つの弾性部材は、連接部と先端部の中間部分の領域において互いに近接するように配置される第1弾性部材を構成する。さらに、第1長尺部材における2つの弾性部材と、第2長尺部材における2つの弾性部材は、連接部と先端部の中間部分の領域において互いに離間するように配置される第2弾性部材を構成する。
そして、第2弾性部材と第1弾性部材とが接合することにより先端部が構成される。
これによって、先端部の近傍に凸部を形成することができるため、保持具を清掃シートに円滑に挿入することが可能となる。
これによって、屈曲開始領域における第2弾性部材の強度を確保することができるため、清掃具が破損し難い構成となる。
図2、図3に示すように、清掃体ホルダ110は、ハンドル部120および清掃体保持部130を主体として構成されている。ハンドル部120は、長尺状に形成されており、清掃時にユーザに保持される部材である。ハンドル部120は、ハンドル121と接合部122を有している。接合部122は、清掃体保持部130の基部132に接合されている。そして、ハンドル121は、接合部122から延在する長尺状に形成されている。このハンドル部120が、本発明における「把持部」に対応する実施構成例である。なお、説明の便宜上、図2の上方および下方を清掃体ホルダ110の右側および左側と称す。また、図3の上方および下方を清掃体ホルダ110の上側および下側と称す。
具体的には、清掃体保持部220は、ポリプロピレン(PP)が使用されている。なお、清掃体保持部220は可撓性を有する樹脂材料を適宜選択することができる。例えば、ポリエチレン(PE)、ポリエチレンテレフタラート(PET)、アクリロニトリル-ブタジエン-スチレン樹脂(ABS)、ポリエステル系の熱可塑性エラストマーを使用できる。
この清掃体保持部130が、本発明における「保持部」に対応する実施構成例である。この凸部137,138が、本発明における「凸部」に対応する実施構成例である。
次に図4~図7を参照しつつ、清掃体140について説明する。清掃体140は、拭き清掃において清掃対象である被清掃面上の汚れを掻き取る汚れ掻き取り機能を有するシート状の清掃体である。図5、図6に示すように、清掃体140は、平面視で長方形状に形成されている。清掃体140の長辺方向は、繊維集合体を構成する複数の繊維が延在する延在方向が交差する方向と概ね合致する。
この溶着接合部171,172,173が本発明における「接合部」に対応する実施構成例である。
次に図8、図9を参照しつつ、清掃体ホルダ110と清掃体140の係合について説明する。図8に示すように、保持部材131はそれぞれ、保持空間180に挿入が可能とされている。保持部材131が保持空間180に挿入されることで、清掃体140が清掃体ホルダ110に保持される。
例えば、第1変形例においては、図10に示すように、溶着接合部271,273が形成されている。溶着接合部271は、清掃体140の長辺方向に平行な直線L1上に形成されている。一方、溶着接合部273は、清掃体140の長辺方向に平行な直線L2上に形成されている。直線L1は、直線L2に対して、中央溶着線170に近接している。そして、溶着接合部273と中央溶着線170によって、保持空間180の中間領域182を形成している。
また、第2変形例においては、図11に示すように、溶着接合線371が形成されている。溶着接合線371は、清掃体140の長辺方向における、保持シート160の一方の端部から他方の端部まで連なった直線状に形成されている。保持シート160の中央領域における、清掃体140の短辺方向の溶着接合線371と中央溶着線170の距離が、保持シート160の端部領域における、清掃体140の短辺方向の溶着接合線371と中央溶着線170の距離よりも広く設定されている。これにより、保持シート160の中央領域において、溶着接合線371と中央溶着線170の間に保持空間180の中間領域182が形成されている。
次に、図12~図21に基づき、第3変形例を説明する。第2弾性部材136は、凸部237と、凸部238とを有する。凸部237は、第2弾性部材136の先端部133側に設けられる。凸部238は、第2弾性部材136の基部132側に設けられる。
引抜方向Y2は、清掃体140の保持空間180に挿入されている清掃体ホルダ110の保持部材131を引き抜く方向である。この引抜方向Y2は、挿入方向Y1と反対を向く方向である。この引抜方向Y2が、本発明における「引抜方向」に対応する実施構成例である。
図13は、清掃体ホルダ110を挿入方向Y1に移動させて、清掃体ホルダ110の保持部材131を、清掃体140の保持空間180に挿入する状態を示す。
この場合、凸部237の挿入側領域237Aが、清掃体140の接合部471に当接する。この挿入側領域237Aが接合部471に最初に当接する点を、挿入開始点237A1とする。この挿入開始点237A1が、本発明における「挿入開始点」に対応する実施構成例である。
この第1の仮想直線L1、第2の仮想直線L2、第1の角度A1が、本発明における「第1の仮想直線」、「第2の仮想直線」、「第1の角度」に対応する実施構成例である。
この場合、凸部237の引抜側領域237Cが、清掃体140の接合部471に当接する。この引抜側領域237Cが接合部471に最初に当接する点を、引抜開始点237C1とする。この引抜開始点237C1が、本発明における「引抜開始点」に対応する実施構成例である。
この第3の仮想直線L3、第4の仮想直線L4、第2の角度A2が、本発明における「第3の仮想直線」、「第4の仮想直線」、「第2の角度」に対応する実施構成例である。
凸部237をこのように構成することによって、清掃体ホルダ110を清掃体140に装着する際には、スムーズに作業を行うことができる。一方、清掃用具100を使用する際には、清掃体ホルダ110と清掃体140とが分離しにくくなる。
次に、図22~図23に基づき、第4変形例を説明する。第4変形例に係る清掃体ホルダ210の清掃体保持部230は、第1弾性部材235と第2弾性部材236とにより構成される。第2弾性部材236は、先端部233側の凸部337と、基部232側の凸部338とを有する。先端部233側の凸部337は、第2弾性部材236の先端部233側を外側方向に変形させることにより形成されている。
さらに、このような構造の凸部337については、特に凸部337の挿入側領域337Aがどこから開始するのかが問題となる。
図23は、清掃体ホルダ210を挿入方向Y1に移動させて、清掃体ホルダ210の保持部材231を、清掃体140の保持空間180に挿入する状態を示す。
この場合、凸部337が、清掃体140の接合部471に当接する。この挿入側領域337Aが接合部471に最初に当接する点を、挿入開始点337A1とする。また、この挿入開始点337A1から中間部337Bに亘る部分を、凸部337の挿入側領域337Aとする。
これにより、凸部337のような構造であっても、上述した第3変形例と同様に、挿入開始点337A1と、挿入終了点とを確定することが可能となる。よって、凸部337においても、第1の角度を決定することができる。
次に、図24~図25に基づき、第5変形例を説明する。図24~図25においては、便宜上、第2弾性部材336と、先端部側の凸部437の構造のみを説明する。
凸部437は、挿入側領域437Aと、引抜側領域437Cが直線により構成されている。よって、中間領域437Bは点状となる。
このような構造の凸部437の場合、挿入終了点437A2と、引抜終了点437C2とが、中間領域437Bにて一致することとなる。一方、挿入終了点437A2と、引抜終了点437C2が凸部437における同一の部分であっても、「第1の角度」および「第2の角度」を求めることに何ら問題はないものである。
次に、図26~図27に基づき、第6変形例を説明する。図26~図27においては、便宜上、第2弾性部材436と、先端部側の凸部537の構造のみを説明する。
凸部537は、挿入側領域537Aに凹部537AAを有する。
凸部537の場合は凹部537AAが存在しているため、挿入領域537Aと接合部471の当接状態は、上述した第3変形例~第5変形例に係る凸部とは異なるものである。
すなわち、凸部537の挿入領域537Aが挿入開始点(図示せず)から挿入終了点537A1に至るまでに、接合部471が凹部537AAを経由する。
一方、仮にこのように挿入領域537Aに凹部537AAを有する構成であっても、あくまで挿入終了点537A2は、挿入側領域537Aが接合部471に最後に当接する点である。このことは、引抜側領域537Cが凹部を有する場合であっても同様である。
よって、凸部537が凹部537AAを有する構造であっても、「第1の角度」および「第2の角度」を求めることに何ら問題はないものである。
この際、例えば清掃体における接合部の形状や、複数存在する接合部の配置形態や、さらには清掃体ホルダの中間部の構成次第においては、長手方向に連続するそれぞれの接合部に対し、第1の角度A1や第2の角度A2が異なった角度となる可能性がある。
このように、複数の第1の角度A1を有する場合は、最も小さい角度を本発明に係る「第1の角度」とする。
さらに、複数の第2の角度A2を有する場合は、最も大きい角度を本発明に係る「第2の角度」とする。
次に、図28~図35に基づき、第7変形例を説明する。清掃体ホルダ610は、挿入方向Y1と平行な方向である清掃体ホルダ長手方向610Yと、清掃体ホルダ長手方向610Yと交差する方向である清掃体ホルダ長手交差方向610Xと、清掃体ホルダ長手方向610Yと清掃体ホルダ長手交差方向610Xの双方と交差する清掃体ホルダ厚さ方向610Zとに延在する。この清掃体ホルダ長手方向610Yが、本発明に係る「保持具長手方向」の一例である。この清掃体ホルダ長手交差方向610Xが、本発明に係る「保持具長手交差方向」の一例である。この清掃体ホルダ厚さ方向610Zが、本発明に係る「保持具厚さ方向」の一例である。
第2弾性部材636における先端部633側の凸部637は、2つの第2弾性部材636同士が互いに離間する方向に向かって延びる凸部離間領域637Aと、第2弾性部材636と第1弾性部材635とが接合する方向へ延びる凸部近接領域637Bとを有する。この凸部離間領域637Aが、本発明に係る「凸部離間領域」の一例である。この凸部近接領域637Bが、本発明に係る「凸部近接領域」の一例である。
なお、先端部633は、第2弾性部材636と第1弾性部材635とが接合する領域に形成される。
屈曲開始領域636Aは、第2弾性部材636において、凸部637、638が設けられている領域に形成される。
なお、第7変形例においては、屈曲開始領域636Aが、凸部637と、凸部638との双方に設けられている構成とされている。一方、屈曲開始領域636Aは、凸部637もしくは凸部638のいずれか一方に形成することもできる。
第1長さD1は、第2長さD2よりも長く形成されている。これによって、ユーザが清掃体140と清掃体ホルダ610とを装着する場合、先端部633を円滑に保持空間180に挿入することができる。さらに、清掃体140と清掃体ホルダ610とが装着されている状態においては、係止基部領域632Aが、保持空間180を形成する構成(基材シート151および保持シート160)とより多く接触することができる。よって、清掃体140と清掃体ホルダ610とが離脱しにくい構成となる。
すなわち、保持部材631における清掃体ホルダ厚さ方向610Zの長さは、引抜方向Y2側から挿入方向Y1側へ向かうに従い、暫時短くなる構成とされる。換言すると、保持部材631は、引抜方向Y2側の領域よりも、挿入方向Y1側の領域の方が薄いものである。これにより、保持部材631は、先端部633側を基部632よりも柔軟とすることができる。この構成により、ユーザは、先端部633側の清掃体140を容易に清掃対象に沿わせることが可能となる。一方、基部632側に対する強度を確保することが可能となる。
第3長さD3は、第4長さD4よりも長く形成されている。すなわち、先端部633はテーパ形状を有している。これによって、ユーザが清掃体140と清掃体ホルダ610とを装着する場合、先端部633を円滑に保持空間180に挿入することができる。
また、第1弾性部材635において、清掃体ホルダ長手交差方向610Xにおける最も長い長さを長さD6とする。
長さD5は、長さD6よりも長く形成されている。この結果、第1弾性部材635は、第2弾性部材636と比して剛性が低くなる。
また、第1弾性部材635において、屈曲が開始される領域の剛性を、当該屈曲が開始される領域以外の領域の剛性より低くすることがあげられる。これは、屈曲が開始される領域における清掃体ホルダ厚さ方向610Zの長さを、他の領域と比して短くすることにより達成することができる。
また、第2弾性部材636の屈曲開始領域636Aの剛性を、屈曲開始領域636A以外の領域の剛性より低くすることがあげられる。これは、屈曲開始領域636Aにおける清掃体ホルダ厚さ方向610Zに長さを、他の領域と比して短くすることにより達成することができる。
また、第1弾性部材635が屈曲により形成する弧および第2弾性部材636が屈曲により形成する弧が、真円における弧であることがあげられる。
図33~図35に基づき、この「最も突出した部分」につき説明する。なお、図33~図35においては、第1弾性部材635と第2弾性部材636の双方を含む概念として、保持部材631が示されている。図33~図35は、保持部材631の断面図である。
図33に示す保持部材631は、清掃体ホルダ厚み方向610Z上の面が平坦である。よって、図33に示す保持部材631は、「最も突出した部分」を有さない。このような場合は、第1弾性部材635と第2弾性部材636における清掃体ホルダ厚み方向610Z上のそれぞれの面を連続した仮想線が、弾性部材連続仮想線L5を形成する。
図34に示す保持部材631は、清掃体ホルダ厚み方向610Z上の面が湾曲している。また、図35に示す保持部材631は、楕円形状とされている。図34および図35に示す保持部材631にあっては、第1弾性部材635と第2弾性部材636における清掃体ホルダ厚み方向610Z上のそれぞれの頂部を連続した仮想線が、弾性部材連続仮想線L5を形成する。
なお、弾性部材連続仮想線L5を形成する領域は、第1弾性部材635と第2弾性部材636とにおける一部の領域でよい。
次に、図36~図37に基づき、第8変形例を説明する。図36は、清掃体ホルダ710の要部を示す平面図である。図37は、図36におけるXIII-XIII線の断面図である。
第8変形例に係る清掃体ホルダ710は、第7変形例に係る清掃体ホルダ610に比して、保持部材の構成が異なる。すなわち、第8変形例に係る保持部材720は、第1保持部材7311の先端部733と、第2保持部材7312の先端部733とが、清掃体ホルダ長手交差方向710Xにおいて互いに重なる領域を有している。換言すると、第1保持部材7311の先端部733と、第2保持部材7312の先端部733とが、清掃体ホルダ厚さ710Zにおいて互いに積層される領域を有している。
また、上記した実施形態および第1変形例~第8変形例を適宜組み合わせることも可能である。
