【発明の属する技術分野】
本発明は、リハビリ用介助車や乳母車に着設して使用されるブレーキ装置に関し、より詳しくは、ブレーキの前部と後部のいずれでも押接固定と解除ができるブレーキ装置に関する。
【0002】
【従来の技術】
従来、リハビリ用介助車や乳母車などに走行ブレーキと別途に、被介助者や赤ん坊を乗せたり、降ろしたりする場合に、停止中の介助車や乳母車が急に動かないように、停止時用のブレーキが設けられている。介助者等が介助車や乳母車の後方から押して進むために、この停止時用のブレーキは一般に介助車や乳母車の後部に設けられている。このために、介助者を必要とするリハビリ用介助車や乳母車などは、後部から介助車や乳母車を押して目的地で停止して、介助者や赤ん坊を降ろすときに一旦ブレーキを掛けて介助車や乳母車を停止固定して、介助車や乳母車の前方に回って被介助者に手を添えて降ろしたり、赤ん坊を抱き降ろしたりしなければならない。被介助者や赤ん坊を降ろした後、介助車や乳母車を収納する場合は、介助車や乳母車の後方に回って、ブレーキを解除してから、介助車や乳母車を片づけるという作業が一般的である。
【0003】
さらに、被介助者や赤ん坊を介助車や乳母車から降ろすときに、もう少し前に進めたいときなどは、後方に回ってブレーキを解除した後、前方に少し押してから再度前に回って、被介助者や赤ん坊を降ろさなければならず、大変面倒であった。そのために、リハビリ用の介助車や乳母車の後部で掛けたブレーキを前部でも解除や再固定ができるようなリハビリ用介助車や乳母車に装着可能なブレーキ装置の出現が望まれていた。
【0004】
【発明が解決しようとする課題】
本願発明は、リハビリ用介助車や乳母車等に装着できるブレーキ装置であって、介助車や乳母車等の前部及び後部のいずれでも押接固定と解除ができるブレーキ装置を提供するものである。
【0005】
【課題を解決するための手段】
前記課題を解決するために、鋭意研究を重ねた結果、リハビリ用介助車や乳母車等に着装して、介助車や乳母車等の前部においても後部においてもタイヤの押接固定と解除が可能なブレーキ装置を創成することに成功した。
【0006】
請求項1に記載の発明は、上端部12eをブレーキ操作を押接部に伝える伝動部12dに回動自在に鋲着し、中間部12fを連結部18に回動自在に鋲着し、下端部12gをブレーキ操作を他方端に伝える連結杆13に回動自在に鋲着したブレーキ操作用のレバー11を有する押動部12hと、中間部12bに前記伝動部12dの上端部を回動自在に鋲着し、下端部12cを連結部18に回動自在に鋲着したタイヤを押接固定する押接部12aと、よりなる左右のブレーキ部12が、前記押動部12hに鋲着された前記連結杆13の他方端に着設された接続部14を介してブレーキ用フレーム15が横架されたブレーキ装置100であって、該ブレーキ装置100が前部でブレーキ操作のできる前記レバー11と後部でブレーキ操作のできる前記ブレーキ用フレーム15が連結杆13により相互に連動して前後でブレーキ操作が可能であることを特徴とする介助車、あるいは乳母車用の下部フレームに着設するブレーキ装置である。ブレーキ部を前部方向に装着した場合、前部のレバーと後部に位置するブレーキ用フレームをそれぞれ連動するように設けることができ、後部のブレーキ用フレームでタイヤを押接固定したブレーキも前部のレバーで解除することができる。この結果、後部のブレーキフレームでブレーキを押接固定して前部に廻り、前部で用事を済ませた後、前部のレバーでブレーキを解除して、回転移動することができる。
【0007】
さらに、左右の連結杆の一方端に接続されたタイヤを押接固定するためのブレーキ部と、該ブレーキ部を操作するレバーと、連結部を介して横架された連結用フレームを有し、前記左右の連結杆の他方端に連結部を介して横架されたブレーキ用フレームとを有するブレーキ装置において、該ブレーキ装置のレバーとブレーキ用フレームが相互に連動することを特徴とするブレーキ装置である。ブレーキ装置の左右の連結杆を介して一方に連結用フレームを他方端にブレーキ用フレームを設けることによって、ブレーキ装置がより強固な構造とすることが出来る。
【0008】
請求項に記載の発明は、ブレーキ装置のブレーキ用フレーム15の中央部に屈折部32を設けてブレーキ装置を折りたたみ可能としたことを特徴とする請求項1に記載の介助車、あるいは乳母車用の下部フレームに着設するブレーキ装置である。ブレーキ部を前部に位置するように装着すると、前部のブレーキレバーと後部のブレーキ用フレームを連動して、後部のブレーキ用フレームでタイヤを押接固定しても、前部のレバーでブレーキを解除することでる。さらに、後部のブレーキ用フレーム及び前部の連結用フレームを折りたたみ可能にすることにより、折りたたみ式の介助車や乳母車等にも装着することができる。
【0009】
請求項に記載の発明は、請求項1または請求項のいずれかに記載のブレーキ装置の連結部18の止着部16a、16bと、接続部14の止着部16cを介助車又は乳母車の下部フレームに着設して請求項1または請求項2のいずれかに記載のブレーキ装置を装着したことを特徴とする介助車又は乳母車である。ブレーキ部を前部に位置するように装着すると、前部のレバーと後部のブレーキ用フレームを連動するように設けることにより、後部のブレーキ用フレームで押接固定したブレーキも前部のレバーで解除することができる。後部でブレーキを掛けて前部に廻り、被介助者を降ろして前部のレバーでブレーキの押接固定を解除して、わざわざ介助車の後に廻ることなく、その場で介助車の回転移動ができる。
【0010】
【発明の実施の形態】
本発明の実施の形態を以下に図面を用いて説明するが、本発明の要旨に含まれる限り以下の実施例に限定されるものではない。
【0011】
本実施例のタイヤを押接固定するブレーキ装置100は、図1に示すようにブレーキ装置100の左右の連結杆13の一方端に設けたブレーキ操作用のレバー11と連結杆13の他方端に設けたブレーキ用フレーム15が相互に連動するように設けられている。左右のブレーキ部12は連結杆13の一方端に接続し、連結杆13の他方端には接続部14を介して後部のブレーキフレーム15が横架されており、連結杆13の一方端のレバー11と他方端のブレーキフレーム15が連動して、ブレーキ装置100を装着した介助車や乳母車等の前後いずれによっても、ブレーキ装置100の押接固定又は解除操作ができることを特徴としている。左右のレバー11はタイヤを押接固定するブレーキ部12に着設されており、ブレーキ部12にはそれぞれ連結杆13の一方端が連結されている。左右の連結杆13の他方端には接続部14を介して後部のブレーキ用フレーム15が横架されて、ブレーキ用フレーム15の作動が前部のブレーキ部12に伝達される。したがって、左右いずれのレバー11の上下動も連結杆13を介して他方端のブレーキ用フレーム15を連動して上下動させることができ、左右のレバー11とブレーキ用フレーム15のいずれの方向からでもタイヤの押接固定と解除を行うことができる。
【0012】
左右の連結杆13のブレーキ部12の下部に連結用フレーム17を設けたブレーキ装置200は図2に示すようになっている。このように左右の連結杆13のブレーキ部12の下部に連結用フレーム17とその他方端にブレーキ用フレーム15を設けることによって、ブレーキ装置100をより強固な構造とすることが出来る。
【0013】
レバー11とブレーキ部12の作動機構は図3に示すように、ブレーキ部12の下端12cは連結部18に回動自在に鋲着されている。さらにブレーキ部12の真ん中よりやや上部12bの位置で伝動部12dの上部12bと回動可能に鋲着されている。伝動部12dは屈曲した押動部12hの上端12eに回動可能に鋲着されている。屈曲した押動部12hはその屈曲した部分12fが連結部18に回動自在に鋲着されている。押動部12hにはレバー11が固設され、さらに押動部12hの下部12gに連結杆13が回動自在に鋲着されている。レバー11を引っ張ると押動部12hの屈曲した部分12fを支点として、伝動部12dが引っ張られてブレーキ部12の押接部12aがタイヤ23に圧接されてタイヤ23を押接固定する。
【0014】
ブレーキ部12の押動部12hを図4の(4−1)に示す形態にすることによって、足踏みレバー19aにすることができる。足踏みレバー19aにするために、図4の(4−2)に示すように、押動部19の一端に足踏みレバー19a用のゴムが取着されている。このようにすることによって、ハンドルを取着する必要がなく、当該押動部19を有するブレーキ装置でタイヤを押接固定、解除する前後のレバー操作は足で簡単に行うことが出来る。レバー操作による押動部19からの力は押接部12dを経てブレーキ部12に伝えられる。ブレーキ部12は図4の(4−3)に示すように、バネ部材18aの付勢力により押接固定、解除ができる。バネ部材18aは図4の(4−4)に示す状態で連結部18とブレーキ部12に着設されている。
【0015】
また、ブレーキ用フレーム15は図5に示すように、連結杆13の他端部に接続部14を介して着設されている。ブレーキ用フレーム15を踏むと図6に示すように、連結杆13によって押動部12hが後方に引かれて、押動部12hの屈曲した部分12fを支点として回動し、伝動部12dがブレーキ部12の押接部12aを押してタイヤ23を押接固定する。押接部12aは押接部12cの下端に付勢された図4の(4−2)に示すトーションバネのようなバネ部材18aで引っ張られており、通常、押接部12aを解放状態に保っている。
【0016】
ブレーキ用フレーム15の下部フレーム21に対する取り付け角度は、図6に示すように、連結杆13の一方端のレバー11と他方端のブレーキ用フレーム15を連動させるために80°〜10°、好ましくは50°〜30°の角度を持たせて踏みやすくする。ブレーキ用フレーム15の取り付け角度が下部フレーム21に対して90°近くになると、レバー11と連動し難くなり、また、ブレーキ用フレーム15を踏んだときにブレーキ用フレーム15が下に降りずに、ブレーキ部12が作動しない等の不都合が生じることがある。また、前記の角度にすることにより、踏み込みやすい角度となり、踏み込むときの力も少なくてすむ。
【0017】
ブレーキ装置100を介助車等に装着するための方法は図6に示すように、介助車の下部フレーム21にブレーキ装置100に設けられた係着部16a、16b、16cをそれぞれネジで強く固定する。このブレーキ装置100を介助車等に装着するに当たっては、ブレーキ用フレーム15を踏みこんだ状態の時に、押接部12aがタイヤ23を押接固定するように連結杆13の中央部に設けられた調節部13aにより連結杆13の間隔を調節して、押接部12aのタイヤ23を押接固定する強さを調節する。
【0018】
折りたたみ可能なブレーキ装置300の形態を図7に示す。ブレーキ用フレーム15によってタイヤを押接固定する場合は、ブレーキ用フレーム15を上から下に踏み込んで押接固定する。解除する場合は、ブレーキ用フレーム15を下から上に蹴り上げるように、上に戻すことにより解除される。ブレーキ用フレーム15の末端部は接続部14に固設され、その固設部分の中央よりに屈折基部31を設けて、この位置から折れ曲がるようにする。さらに、ブレーキ用フレーム15の中間部に屈折部32を設けて折りたたみ可能とする。
【0019】
屈折基部31の折り曲げの方式は図8に示すように、ブレーキ用フレーム15の両端部の接続部14に連結されたブレーキ用フレーム15の接続部14に近い位置の屈折基部31を、図8の(8−1)の上面図、及び(8−2)の側面図に示すように、ブレーキ用フレーム15の末端は接続部14に螺着され、螺着部位から少し離れた位置にフィンガージョイントの屈折基部31を設け、このフィンガージョイントの中心部を回動可能にネジで固定されている。
【0020】
さらに、図9に示すように、ブレーキ用フレーム15の中央部にフィンガージョイントによる回動可能な屈折部32を設けて、ブレーキ用フレーム15の屈折部32から斜め後方に折れまがるようにした。また、ブレーキ用フレーム15の中央部に設けた屈折部32には、屈折部32を保護するために屈折部32の上部にブレーキ用フレーム15の径の略半分を覆う半円状の保護部材33を装着した。屈折部32に保護部材33を装着することにより、ブレーキ用フレーム15を上から踏み込んでも屈折部32が過剰に下がらないように保護することができる。ここで使用するブレーキ用フレーム15は平板状でも円柱状の棒状体であっても良い。
【0021】
ブレーキ装置100の前部と後部のいずれでもタイヤを押接固定と解除ができるブレーキ装置100を介助車に装着した実施例を図10に示す。介助車の背面より示したものであるが、本実施例のブレーキ装置100を介助車の下部フレーム21に取りつけるためには、介助車のタイヤ23にブレーキ部12aが当接して(図6)、タイヤ23を押接固定するように装着位置を定めた上で、介助車の両側の下部フレーム21にブレーキ装置100の止着部16a、16b、16cを螺着する穴を設けて、ブレーキ装置100を介助車の下部フレーム21に横架する。介助車にブレーキ装置100を装着後、連結杆13の中央部に設けられている調節部13aのネジを緩めて連結杆13の間隔を調節し、ブレーキ部12aがタイヤ23に当接して押接固定するように調節してネジを締める。
【0022】
本実施例で得られたブレーキ装置100は、前記介助車の他に乳母車などの後方から介助者が押して、後部でブレーキを掛けて、前方で解除する必要のあるものに容易に着設することができる。
【0023】
【発明の効果】
本発明のブレーキ装置のブレーキ部を前部に位置するように装着すると、前部にブレーキ部と該ブレーキ部を操作することができるレバーと後部に前記ブレーキ部を操作することができるブレーキ用フレームを設けて前後のブレーキ操作を連動させたブレーキ装置とすることにより、後部のブレーキ用フレームを踏んで押接固定したブレーキも前部のレバー操作で容易に解除することができる。
【0024】
本発明のブレーキ装置を介助車に装着することによって、後部のブレーキ用フレームを踏んでタイヤを押接固定して前部に廻り、被介助者を降ろして、前部のレバーによってブレーキを解除して、その場で介助車の回転移動ができる。また、後部でタイヤを押接固定して前部に廻り、少し動かしたい時も前部のレバーでブレーキを解除できるので、わざわざ介助車の後部に回る必要がなくなる。
