Description

【0001】
【発明の属する技術分野】
本発明は、パイプの端部等に装着されるキャップに関する。
【0002】
【従来の技術】
従来、パイプを用いたテーブルや椅子等の脚であるパイプ切断端部には、床の傷防止や安全性の面から樹脂製のキャップが脚端部に設けられている。このキャップは椅子等の使用中に脱落することのないように、脚端部にかなりきつめに圧入されるのが一般的であり、かつ溶着剤等で取外し不可に固定されるものがある。
【0003】
近年においては、省資源化によるリサイクルのため、上記テーブルや椅子を廃棄する場合や部品の交換時に、パイプからキャップを取り外し、分別処理したいという要望がある。
【0004】
そこで、近年の技術ではパイプとキャップを分別処理できるようにした、例えば特許登録第3057483号公報に開示されているものがある。この発明は、キャップにキャップの内孔に開口する開口部が設けられ、この開口部はドライバー等の刃先を差し込める幅を有している。キャップを取り外す際は、ドライバー等の刃先を開口部から内孔にドライバー等を差し込み、ドライバー等を脚端部にあてることにより、梃子の作用によって脚端部に圧入されているキャップを簡単に取り出すことができるようになっている。
【0005】
しかし、このキャップは、その内部へ貫通する開口部が設けられており、キャップの製造過程において、開口部からキャップ内部へドライバーの差込孔が設けられた金型は複雑な構造を必要とし、金型製造の手間や時間、費用の面で課題があった。
【0006】
また、このキャップを簡単に取り外すためには、梃子の作用を用いるためドライバー等が脚端部に当り、脚端部に変形や傷等が残ることがあり、さらにこの構造であると、キャップ本体の強度の面でも問題がある。
【0007】
【発明が解決しようとしている課題】
本発明のパイプ端用キャップは、テーブルや椅子等の廃棄やリサイクル時に、脚端部に圧入されたキャップをパイプ本体等に傷つけることなく、簡易な工具で簡単に取り外し、部品の分別処理や交換が容易に行え、かつキャップ本体の製造過程で複雑な金型を必要としないパイプ端用キャップを提供することを目的としている。
【0008】
【課題を解決するための手段】
上記目的を達成するために、本発明のパイプ端用キャップは、パイプ端に取り付けられるパイプ端用キャップにおいて、キャップ前記パイプ端よりパイプの内部に圧入して嵌合される嵌入部と、前記パイプ端の下方に当接する支持面と、前記パイプ端の外径とほぼ同径の基部と、からなり、前記キャップに、前記支持面の前記パイプ端との当接箇所から前記基部の外周面にかけて開口する凹部を設け、前記凹部の下端面内径側が凹没した凹没部からなる工具受部を形成し、前記凹没部に工具を差し込み押下して前記キャップを取り外すことを特徴としている。この特徴によれば、前記キャップを、パイプから取り外す場合、ドライバー等の工具を前記開口部から差し込み、工具を工具受部に当てて下方へ力を加えるだけで、圧入されたキャップをパイプの端縁部等を傷つけることがなく、簡単に取り外すことができる。また、キャップ基部の凹部が内孔に連通していない凹構造なので、複雑な金型を必要とせず容易に製造することができる。特にパイプとキャップ基部がほぼ同径であるため、段部が表出せず、ほこり等がたまる心配もない。更にドライバー等の工具の先端がしっかりと工具受部の凹没部に固定されることになり、工具の先端に加わる力が効果的に凹没部に集中し、取り外せる。
【0010】
上記パイプ端用キャップにおいて、パイプ端に取り付けられるパイプ端用キャップにおいて、該キャップは、前記パイプ端よりパイプの内部に圧入して嵌合される嵌入部と、前記パイプ端の下方に当接する支持面と、前記パイプ端の外径とほぼ同径の基部と、からなり、前記キャップに、前記支持面の前記パイプ端との当接箇所から前記基部の外周面にかけて開口する凹部を設け、前記凹部の下端面が内側が深くなるように傾斜した傾斜面からなる工具受部を形成し、前記傾斜面内方に工具を差し込み押下して前記キャップを取り外すことを特徴としている。このようにすれば、キャップをパイプの端部から取り外す時、ドライバー等の工具が、開口部から工具受部へと案内され、工具受部にしっかりと固定されて、安定するため、取り外しが確実になる。
【0012】
上記パイプ端用キャップにおいて、前記凹部が、前記基部の外周に複数箇所に設けられている。このようにすれば、キャップをパイプの端部から取り外す時、ドライバー等の工具を複数箇所に設けられた凹部へ複数回に分けて、または同時に複数個の工具で力を加えることが可能なため、より簡単にキャップの取り外しが可能になる。
【0013】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。
【0014】
図1ないし図4に基づいて本発明の第1実施例を説明すると、図1はキャップ1を椅子13の脚端部3に圧入した斜視図であり、図2にはキャップ1が脚端部3に圧入された状態が示されている。
【0015】
このキャップ1は、パイプ脚2の脚端部3とほぼ同径の基部11と、その上部に一体に延出した小径の嵌入部5とから成り、この基部11と嵌入部5との径の違いから基部11の上部に支持面8が形成されている。さらにこのキャップ1の前記嵌入部5には、パイプ脚2における脚端部3のパイプ穴内周面に対して若干外方に張出すように縦方向に弾性凸部7が形成され、キャップ1をパイプ穴に圧入した際、容易に抜けないような構造になっている。また、前記した基部11の上部の支持面8には、基部11の外周面8’にかけて凹部10が複数個形成されている。なお凹部10は1個でもよい。
【0016】
上記構造のキャップ1がパイプ脚2の脚端部3に嵌入されると、図2に示されるように、嵌入部5がパイプ脚2内に没入するとともに、基部11とパイプ脚2の脚端部3との径がほぼ同径のため、パイプ端縁4を境界線として段部のないほぼストレートな脚が形成される。この嵌入によって、キャップ1の基部11の外周面8’に凹部10が残り、これが後述する工具を差し込む開口部12となる。なお、この実施例における凹部10の下端面はほぼ水平な面であり、ここが後述する工具が差し込まれた際の工具受部9になっている。
【0017】
図3、図4には、脚端部3に圧入されたキャップ1を容易に取り出す工程が示され、まずドライバー等の工具6を前記キャップ1の基部11に開口する開口部12から工具受部9へ差し込む。そして、工具6の先端を工具受部9へ当て、図4に示すようにキャップ1を押し下げることによって脚端部3からキャップ1を取り外すことができる。なお工具を押し下げる際に、手またはハンマー等を用い、ドライバー等の工具6の後端を叩くことによって、より簡単にキャップ1を取り外すことが可能である。
【0018】
図5は本発明の第2実施例を示した図であり、前記第1実施例と相違する点は、基部11に形成された凹部10の工具受部9に凹没部15が設けられている点である。このようにすれば、ドライバー等の工具6の先端がしっかりと工具受部9の凹没部15に固定されることになり、工具6の先端に加わる力が効果的に凹没部15に集中し、取り外せる。
【0019】
図6は本発明の第3実施例を示した図であり、前記第1実施例と相違する点は、基部11に形成された凹部10の下端面である工具受部9が、内側が深くなるように傾斜している点である。このように、開口部12から内側へ傾斜する工具受部9が設けられることによって、工具6が確実に基部11の中心方向へ案内され、ドライバー等の工具6の先端がしっかりと工具受部9に固定されることになり、工具6の先端に加わる力が効果的に工具受部9に集中し、取り外せる。
【0020】
図7は本発明の第4実施例を示した図であり、第1実施例と相違する点は、基部11に形成された凹部10の下端面である工具受部9に、滑り止めとしての凹凸14が設けられている点である。このように工具受部9に滑り止め用の凹凸14が施されていることにより、ドライバー等の工具6先端部の角が凹凸14に引っかかることにより滑りにくくなり、工具6の先端が工具受部9から外れにくくなっている。また、上記凹凸の深さや目の大きさを変更して摩擦力を変えることが可能であり、パイプやキャップ1の形状や用途等により、状況に応じて適したものを採用すればよい。
【0021】
第5実施例の図8は本発明の種々の実施適用例を示しており、
(a)は基部11の開口部12が半円形になっているものであり、この開口部12から工具受部9にかけて丸みを帯びていることにより、ドライバー等の工具6先端部が、工具受部9のほぼ中心下端に案内され、パイプ脚2からキャップ1を簡単に取り外せることができる。
(b)はパイプ脚2が角形になっており、キャップ1もパイプ脚2に倣って角形の形状を適用したものである。
(c)はパイプ脚2が楕円になっており、キャップ1もパイプ脚2に倣って楕円の形状を適用したものである。
【0022】
上記実施例において示したように、キャップ1に凹部10が複数箇所設けられていることにより、ドライバー等の工具6をこれら複数箇所の工具受部9へ当接させ、押し下げ力を加えることにより、脚端部3を傷付けることなく、キャップ1を脚端部3から直線的に取り出すことができる。また、凹部10は、工具受部9を構成していれば、その形状や大きさ等は限定されるものではなく、図8(a)〜(c)に示されるように、種々に変形可能である。
【0023】
以上のように本発明は、上記実施例に限定されるものではなく、種々の実施形態を採りえる。
【0024】
【発明の効果】
本発明によれば、次のような効果が得られる。
【0025】
(a)請求項1に記載の発明によれば、前記キャップを、パイプから取り外す場合、ドライバー等の工具を前記開口部から差し込み、工具を工具受部に当てて下方へ力を加えるだけで、圧入されたキャップをパイプの端縁部等を傷つけることがなく、簡単に取り外すことができる。また、キャップ基部の凹部が内孔に連通していない凹構造なので、複雑な金型を必要とせず容易に製造することができる。特にパイプとキャップ基部がほぼ同径であるため、段部が表出せず、ほこり等がたまる心配もない。更にドライバー等の工具の先端がしっかりと工具受部の凹没部に固定されることになり、工具の先端に加わる力が効果的に凹没部に集中し、取り外せる。
