【考案の属する技術分野】
本考案は一種の椅子の組合せ式足乗せ装置に係り、特に二つの異なる部品が組み合わされてなる円環形の足乗せ装置であり、相互に分解、組合せが行える便利性を具え、使用者が椅子のシートを取り外さなくとも、組み付けと取り外しが行える椅子の組合せ式足乗せ装置に関する。
【0002】
【従来の技術】
従来の椅子10(図1、2参照)は、キャスタ付きの足フレーム12の上方に、直立する支柱11でシートが支持されてなり、子供が使用時に両足を置けるように、シートの下方の支柱11に円環形の足乗せ装置30が固定されている。この足乗せ装置30に使用者が両足を乗せることができる。この足乗せ装置30は円環形を呈し、中心の貫通孔32により支柱11に套設される内環31と外環32で組成され、且つ内環31と外環33の間が複数の連接リブ34で連結されている。ゆえに足乗せ装置30が支柱11に套設されると共に、ボルトで支柱11の適当な高さに固定され、使用者の両足を乗せるのに供される。
【0003】
このような足乗せ装置30を椅子10の支柱11に取り付けるか、或いは椅子10の支柱11より取り外す時には、必ず先に椅子10のシートを取り外さねば足乗せ装置30の着脱が行えず、これが業界の克服すべき欠点である。
【0004】
【考案が解決しようとする課題】
本考案の主要な目的は、一種の椅子の組合せ式足乗せ装置を提供することにあり、それは、二つの異なるユニットを相互に組み合わせて円環形としてなる足乗せ装置であり、足乗せ装置の椅子への取り付け、取り外し時に、シートを取り外す必要を無くしたものとする。
【0005】
本考案の次の目的は、一種の椅子の組合せ式足乗せ装置を提供することにあり、それは、二つのユニットの一方に嵌合溝を設け、もう一方に嵌合板を設け、嵌合溝と嵌合板を相互に嵌合させ固定する技術手段により、組合せの強固性を達成するものとする。
【0006】
本考案のさらに別の目的は、一種の椅子の組合せ式足乗せ装置を提供することにあり、それは二つのユニットの外周接合部分に対応する嵌合凹溝を設け、並びに位置決めリブとネジ孔を設ける技術手段により、組合せ時にネジで固定して強固な組合せを達成するものとする。
【0007】
【課題を解決するための手段】
請求項1の考案は、椅子の支柱の適当な高度部分に取り付けられて使用者の両足を乗せるのに供される足乗せ装置とされ、異なる円弧径の第1ユニットと第2ユニットが相互に組み合わされてなり、第1ユニットが円環形の内環と外環間が複数の連接リブで連接されて、内環の中心に支柱に嵌合しうる貫通孔が設けられ、両側の内側辺に嵌合溝が嵌合溝が設けられ、外環の内側辺に凹溝が凹設され、第2ユニットが複数の連接リブで連接された内環と外環を具え、第2ユニットの内環に支柱に嵌合しうる円弧凹溝が設けられ、第2ユニットの外側両側辺に嵌合板が凸設され、第2ユニットの外環両側端縁底部に凹溝が設けられ、第2ユニットの該凹溝にネジ孔が設けられ、該嵌合板と該嵌合溝が相互嵌合され、並びにボルトで支柱の適当な高度部分に固定され、且つ第1ユニットと第2ユニットの外環がそれぞれの凹溝により嵌合され、さらにボルトで固定され、こうして足乗せ装置が椅子の支柱に取り付けられ、第1ユニットと第2ユニットを分解すれば支柱より取り外すことができ、椅子のシートを取り外さずに足乗せ装置の着脱が行えるよう形成されたことを特徴とする、椅子の組合せ式足乗せ装置としている。請求項2の考案は、請求項1記載の椅子の組合せ式足乗せ装置において、ボルトによる支柱への取り付けに供される足乗せ装置の円弧凹溝部分に、凹溝が設けられて活動式の楔板が嵌合され、ボルトの端縁の支持固定に供されることを特徴とする、椅子の組合せ式足乗せ装置としている。

請求項4の考案は、請求項1又は請求項2記載の椅子の組合せ式足乗せ装置において、嵌合板が全体が金属板で成型されて嵌合強度が増されたことを特徴とする、椅子の組合せ式足乗せ装置としている。
【0008】
【考案の実施の形態】
図3、4に示されるように、本考案は椅子10の支柱11の適当な高度部分に取り付けられて使用者の両足を乗せるのに供される足乗せ装置20である。本実施例は二つの異なる円弧径のユニットが相互に組み合わされてなり、そのうち、大円弧径の第1ユニットは円環形の内環21と外環23間が複数の連接リブで連接され、並びに一側に適当な円弧形の切欠き28が形成され、内環21の中心に支柱11に対応する貫通孔22が設けられ、切欠き28の二つの内側辺に嵌合溝24が設けられ、別に外環23に、切欠き28に隣接する内側辺に凹溝25が凹設され、並びに該凹溝25に貫通孔26が設けられている。別に小円形の第2ユニットは切欠き28に対応する円弧径を具え、該第2ユニットも複数の連接リブ42で連接された内環40と外環43を具え、内環40に支柱11に対応する円弧凹溝が設けられ、並びに外側の二側辺に嵌合板41が設けられ、外環43の両側端縁底部に凹溝44が凹設され、並びに該凹溝44にネジ孔45が設けられている(図5参照)。
【0009】
組付け時には、第1ユニットと第2ユニットが嵌合板41と嵌合溝24の嵌合により組み合わされ、並びにボルト47で支柱11の適当な高度位置に固定され、且つ第1ユニットと第2ユニットの外環23、43の両端がそれぞれ凹溝25、44で係合し、さらにボルト27で固定されることにより、足乗せ装置20が椅子10の支柱11に組み付けられる。反対に、両者を分解すれば支柱11より取り外せ、こうして椅子10のシートを排除しなくとも足乗せ装置20の着脱が行える機能を達成している。
【0010】
続いて、図6に示されるように、嵌合板41は全体が金属板で成型されることにより、二つのユニットの嵌合後の強度を増加できる。内環40の円弧凹溝にさらに凹溝46が設けられ、並びに底端縁に切欠き48が設けられ、楔板50が凹溝46内に挿入されてボルト47による螺子止め時の支持に供される。さらに楔板50の底端に係止突起51が設けられて切欠き48との係合に供され、係止突起51と切欠き48の係合作用により、楔板が力を受ける時の滑動が防止される(足乗せ装置20使用時の受力は下向き方向であるため、楔板50の底端縁に抵抗力がなければ、楔板50が凹溝46内で滑動を発生しやすく、そのために足乗せ装置20が下に滑る)。
【0011】
【考案の効果】
総合すると、本考案は二つの異なるユニットが組み合わされて円環形とされてなる足乗せ装置20の技術手段であり、従来の技術を用いながら、足乗せ装置20の着脱に運用されることで、操作上の敏捷性を高める進歩性機能を達成している。なお、本考案の構造はその出願前に公開されておらず、新規性を具え、ゆえに本考案は実用新案登録の要件に符合している。なお、以上の実施例は本考案の実施範囲を限定するものではなく、本考案に基づきなしうる細部の修飾或いは改変は、いずれも本考案の請求範囲に属するものとする。
