Description

【０００１】
【発明の属する技術分野】
本発明は例えば身障者、病人、老人に適した車椅子に関するものである。
【０００２】
【従来の技術】
この種の車椅子として、フレーム部材に押手部、座部、左右の支持車輪及び左右の前輪を備えてなる構造のものが知られている。
【０００３】
【発明が解決しようとする課題】
しかしながら上記従来構造の場合、フレーム部材に側フレームが一体的に設けられ、この側フレーム部に支持車輪が設けられているので、一般的に車椅子の乗り降りは側フレーム部及び支持車輪を避けてフレーム部材の前方又は斜め前方から行われることになり、このため、乗り降りが非常に厄介であり、身障者等にとっては大変な労苦を強いることになると共に介護者を必要とすることになるという不都合を有している。
【０００４】
【課題を解決するための手段】
本発明はこのような課題を解決することを目的とするもので、本発明のうちで、請求項１記載の発明は、フレーム部材１に押手部４、座部５、左右の支持車輪８・８及び左右の前輪６・６を備えてなり、上記フレーム部材１を本体フレーム部２及び該本体フレーム部２の左右両側に設けられた一対の側フレーム部３・３により形成し、上記各側フレーム部３・３に上記左右の支持車輪８・８を設け、該本体フレーム部２に上記押手部４、座部５及び左右の前輪６・６を設け、少なくとも一方の側フレーム部３の基部を該本体フレーム部２に枢着部７により枢着して該少なくとも一方の側フレーム部３を該フレーム部材１の側部が開放状態となるように水平旋回自在に設け、かつ、該本体フレーム部２と側フレーム部３との間に着脱機構１１を設け、該着脱機構１１として、上記側フレーム部３の水平旋回する部分に筒状摘子１１ｃを上下摺動自在に設け、該筒状摘子１１ｃに上下方向に延びる係止突片１１ｄを形成し、上記本体フレーム部２の上記筒状摘子１１ｃに対向可能な部分に係止片１１ａを突設し、該係止片１１ａに該係止突片１１ｄが上方から挿入自在であると共に該係止突片１１ｄが上方へ抜脱自在な挿通孔１１ｂを形成し、該側フレーム部３と該筒状摘子１１ｃとの間に該筒状摘子１１ｃを下方に弾圧して該係止突片１１ｄと該挿通孔１１ｂとの挿入状態を保持可能な係止用バネ１１ｅを設けて構成したことを特徴とする車椅子にある。
【０００５】
又、請求項２記載の発明は、上記側フレーム部に掴持可能な肘掛部を設けてなることを特徴とするものである。
【０００６】
【発明の実施の形態】
図１乃至図９は本発明の実施の形態例を示し、１はフレーム部材であって、このフレーム部材１は本体フレーム部２及び側フレーム３・３部により形成され、本体フレーム部２に押手部４及び座部５を設けると共に左右に前輪６・６を設け、側フレーム部３・３はいずれも本体フレーム部２に縦軸としての枢着部７・７により水平旋回自在に設けられ、各側フレーム部３・３に大径の支持車輪８・８を設けて構成している。
【０００７】
この場合、本体フレーム部２の前部左右に折畳可能な足置部材９・９を設けると共に各側フレーム部３・３に肘掛部１０・１０を設けて構成している。
【０００８】
又、この場合、本体フレーム部２に側フレーム部３・３を縦軸としての枢着部７・７により走行方向と直交方向との間で水平旋回自在に設け、本体フレーム部２と側フレーム部３との間に着脱機構１１を設け、この場合、着脱機構１１として、上記側フレーム部３の水平旋回する部分に筒状摘子１１ｃを上下摺動自在に設け、該筒状摘子１１ｃに上下方向に延びる係止突片１１ｄを形成し、上記本体フレーム部２の上記筒状摘子１１ｃに対向可能な部分に係止片１１ａを突設し、該係止片１１ａに該係止突片１１ｄが上方から挿入自在であると共に該係止突片１１ｄが上方へ抜脱自在な挿通孔１１ｂを形成し、該側フレーム部３と該筒状摘子１１ｃとの間に該筒状摘子１１ｃを下方に弾圧して該係止突片１１ｄと該挿通孔１１ｂとの挿入状態を保持可能な係止用バネ１１ｅを設け、しかして、走行使用時において、係止突片１１ｄを挿通孔１１ｂに挿通して側フレーム部２を本体フレーム部２に固定配置し、乗り降り時において、係止突片１１ｄを係止用バネ１１ｅに抗して挿通孔１１ｂから抜き外し、側フレーム３を走行方向から側方に向けて、例えば９０度分水平旋回させ、図示省略の固定機構により位置固定することになる。
【０００９】
この実施の形態例は上記構成であるから、走行使用時には、図１乃至図３の如く、支持車輪７・７が走行方向に向いた状態とすることになり、又、乗り降り時においては、図７乃至図９の如く、乗り降り側の側フレーム部３を本体フレーム２に対して枢着部７・７を中心として側方に水平旋回させることができ、この水平旋回によりフレーム部材１の側部が開放状態となり、このため、座部５への乗り込みを開放状態となっている位置から行うことができると共に座部５から降りるときも開放状態となっている位置から行うことができ、それだけ、乗り降りを容易に行うことができ、身障者、病人、老人等にとって、乗り降りの労苦を軽減することができて使用の利便性を高めることができる。
【００１０】
又、この場合、上記本体フレーム部２に前輪６・６を設けているから、乗り降り時に側フレーム部３を側方に水平旋回させた状態においては、支持車輪８・８と前輪６・６とによりフレーム部材１を支持することができ、乗り降りを良好に行うことができ、又、この場合、上記側フレーム部３に肘掛部１０を設けているので、側フレーム部３を側方に水平旋回させた状態において、乗り降りするとき、肘掛部１０を掴んで乗り降りすることができ、一層楽に乗り降りを行うことができ、使用の利便性を高めることができる。
【００１１】
尚、本発明は上記実施の形態例に限られるものではなく、フレーム部材１、本体フレーム部２、側フレーム部３及び側フレーム部３の水平旋回構造、形状等は適宜変更して設計され、例えば、一方の側フレーム部のみを水平旋回させる構造とすることもある。
【００１２】
【発明の効果】
本発明は上述の如く、請求項１記載の発明にあっては、フレーム部材に押手部、座部、左右の支持車輪及び左右の前輪を備えてなり、上記フレーム部材を本体フレーム部及び該本体フレーム部の左右両側に設けられた一対の側フレーム部により形成し、上記各側フレーム部に上記左右の支持車輪を設け、該本体フレーム部に上記押手部、座部及び左右の前輪を設け、少なくとも一方の側フレーム部の基部を該本体フレーム部に枢着部により枢着して該少なくとも一方の側フレーム部を該フレーム部材の側部が開放状態となるように水平旋回自在に設け、かつ、該本体フレーム部と側フレーム部との間に着脱機構を設け、該着脱機構として、上記側フレーム部の水平旋回する部分に筒状摘子を上下摺動自在に設け、該筒状摘子に上下方向に延びる係止突片を形成し、上記本体フレーム部の上記筒状摘子に対向可能な部分に係止片を突設し、該係止片に該係止突片が上方から挿入自在であると共に該係止突片が上方へ抜脱自在な挿通孔を形成し、該側フレーム部と該筒状摘子との間に該筒状摘子を下方に弾圧して該係止突片と該挿通孔との挿入状態を保持可能な係止用バネを設けて構成したから、走行使用時には、係止突片を挿通孔に挿通して側フレーム部を本体フレーム部に固定配置し、支持車輪が走行方向に向いた状態とすることになり、又、乗り降り時においては、係止突片を係止用バネに抗して挿通孔から抜き外し、乗り降り側の側フレーム部を本体フレームに対して側方に水平旋回させることができ、この水平旋回によりフレーム部材の側部が開放状態となり、このため、座部への乗り込みを開放状態となっている位置から行うことができると共に座部から降りるときも開放状態となっている位置から行うことになり、それだけ、乗り降りを容易に行うことができ、身障者、病人、老人等にとって、乗り降りの労苦を軽減することができて使用の利便性を高めることができ、かつ、上記本体フレーム部に前輪を設けているから、乗り降り時に側フレーム部を側方に水平旋回させた状態においては、支持車輪と前輪とによりフレーム部材を支持することができ、乗り降りを良好に行うことができる。
【００１３】
又、請求項２記載の発明にあっては、上記側フレーム部に掴持可能な肘掛部を設けているので、側フレーム部を側方に水平旋回させた状態において、乗り降りするときに肘掛部を掴んで乗り降りすることができ、一層楽に乗り降りを行うことができ、使用の利便性を高めることができる。
【００１４】
以上、所期の目的を充分達成することができる。
