Description

【0001】
【発明の属する技術分野】
本発明は、柄付ブラシに関する。
【0002】
【従来の技術】
ブラシ台と柄とを着脱自在とし、不使用時に分離して収納するようにした柄付ブラシは、従来より周知である。
その一例として、図4に示すように、柄付ブラシが従来より知られている。
図4において、aはブラシ台、bはブラシ台に着脱自在に取り付けられた柄である。
ブラシ台aの取付段部cには、アリ溝dを削設し、柄bの取付板eの両側には、アリ溝dに嵌合する三角状の突条fを形成し、ブラシ台aの取付段部cに柄bの取付板eを差し込むようにして両者を結合していた。
【0003】
【発明が解決しようとする課題】
しかしながら、ブラシの使用時には、ブラシ台aと柄bとの間に、ねじりモーメントが働き、嵌合が斜面の接合によるため、ときには柄bの取付板eが外れるということが起こり、結合が安定しないという問題があった。
また、従来、ブラシ台aと柄bは、同材質で、ポリプロピレンのような硬質の合成樹脂で成形されていた。
そのため、嵌合にあたって、両者の間の締め代を多くとることができないという問題があった。
【0004】
本発明は、上記の問題点を解決することを課題とし、ねじりモーメントに対する抗力を大きくし、ブラシ台と柄が簡単に外れないようにしたブラシを提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明は、上記の課題を解決するため、ブラシとして、軟材質の合成樹脂で成形されたブラシ台と、硬質の合成樹脂で成形された柄とを組立分離自在としたブラシであって、ブラシ台は、下面にブラシ歯を立設し、上面に柄取付のための取付段部を設け、該取付段部の両側には、底面に沿って凹溝が削設され、該凹溝によって、水平の底面と、該底面の端部から垂直に立ち上がる側壁と、該側壁から内側に水平に延びる上面とから構成される断面コの字状の取付段部の側部が形成されており、該取付段部の側部間の巾は内端縁に近づくにしたがって細巾となっており、取付段部の底面には、係合突起が突出するよう配設されており、柄の取付板の先端部分には、両側縁から一定の間隔をおいてスリットを削設して突出片を形成し、該突出片の外側部に、前記凹溝に係合し一定の締め代をもって嵌合される凸条を設け、取付板の底面には、前記係合突起に係合する凹部が設けられていることを特徴とする構成を採用する。
【0006】
【発明の実施の形態】
次に、本発明の実施形態について、図面を参照して説明する。
図1において、Aはブラシ台で、低密度ポリエチレン、線状低密度ポリエチレン、その他軟質の合成樹脂で形成され、Bは柄で、ポリプロピレン、その他硬質の合成樹脂で成形されている。
【0007】
図2に示すように、ブラシ台Aは、その下面1には多数のブラシ歯2が立設されており、上面3には、柄Bを取付ける長方形の取付段部4が形成されている。
取付段部4の両側縁には、取付段部4底面から水平方向に延びる凹溝5a,5bが削設され、凹溝5a,5bの溝底間の巾は内端縁6に近づくにしたがって細巾となっており、取付段部4の内端縁6近くには、係合突起7が突設されている。
【0008】
図3に示すように、柄Bは、ブラシ台Aに結合する取付板10と把手11とからなっている。
取付板10は、ブラシ台Aの取付段部4の深さにほぼ等しい厚さの長方形の板状体で、両側縁には、下面に沿ってブラシ台Aの凹溝5a,5bに嵌合する凸条12a,12bが形成されている。
取付板10の先端には、両側縁から一定の間隔をおいて、スリット13が削設され、左右の突出片14a,14bと中央の舌片15が形成されており、中央の舌片15の下面には、ブラシ台Aの取付段部4に設けられた係合突起7に係合する凹部16が凹設されている。
【0009】
把手11は、取付板10の中央から後端にかけ、立設された板体17a,b,c,dからなる根本部18と表面に複数個の凹部20を設けた握り部19とからなっている。
【0010】
次に、ブラシの組立とその際の作用効果について説明する。
ブラシ台Aと柄Bは、二体として収納ケースに収納され、使用にあたって組立られる。
組立にあたっては、柄Bの取付板10をブラシ台Aの取付段部4に、取付板10の凸条12a,12bが取付段部4の凹溝5a,5bに嵌合するように押し込み、先端まで押し込むと、ブラシを組立ることができる。
【0011】
その際、ブラシ台Aの凹溝5a,5b間の巾が内端にいくほど細くなっているので、取付段部4と取付板10との間での締め代が大きくなるとともに、両端縁の突出片14a,14bが内方に偏寄され、強く嵌合されることになる。
次いで、柄Bの取付板10が取付段部4の先端に達すると、取付板10の凹部16が取付段部4の係合突起7に係合し、ブラシ台Aと柄Bは強く結合される。
【0012】
前記実施形態では、ブラシとして、ブラシ台と同じ合成樹脂を用いてブラシ歯を一体成形により立設するようにしているが、毛、毛集束体等をブラシ台に植立てしてもよく、合成樹脂製のブラシ歯に限定されない。
【0013】
【発明の効果】
本発明は、上記のように構成されているから、次の効果を奏する。
結合にあたって、ブラシ台は低密度ポリエチレン等柔軟な合成樹脂で成形され、柄はポリプロピレン等比較的硬質の合成樹脂であるので、締め代を大きくとることができ、また、凸条と凹溝を嵌合させることで、ねじりモーメントを直角な面で受けるようにしているので、反力を大きくすることができ、使用中に、両者が外れるようなことはない。
