Description

【0001】
【発明の属する技術分野】
本発明は、回転体を機器や装置本体に回動可能に付設する場合に用いられる回動装置に関するものである。
【0002】
【従来の技術】
この種の回転体はリッドや扉等であり、機器類や収納装置等の本体に枢軸を介し開位置と閉位置に回動可能に組み付けられる。この場合、回転体は、特許第2880943号に例示される如く、本体との間に設けられたラッチ(ロック手段)により閉位置に係止されたり、本体との間に介在されたばね部材(付勢手段)で開位置方向へ付勢されたり、枢軸に作用する制動用ダンパーによりその回動速度を緩やかになるよう制動したりして使い勝手を良好にし品質向上を図るよう処理される。ところが、前記した機能部品であるラッチ、ばね部材、ダンパー等は回転体を回動可能に枢支する枢軸と別個にぞれ付設する構成だと、設置個所の確保に苦労したり組立手順も煩雑になる等の不具合がある。
【0003】
そこで、従来構造には、図15や図16に例示される如く前記の機能部品をできるだけユニット化することにより組立性、部品管理、設計自由度等を改善したものもある。各図の(a)は本体及び回転体と回動装置ないしはユニット品の配置を示し、各図の(b)はそれらユニット品の要部を示している。図15のユニット品80は、実用新案登録第2562129号に開示されているもので、有底筒状の軸受81と、係合軸部82a及び軸受81内に回動可能に組み付けられる挿入軸部82bを有する軸部材82と、挿入軸部82bに設けられた長溝82cに充填される粘性体83と、軸部材82と軸受81との間に介在されて粘性体83の流出を防ぐ封止体84とからなり、軸受81が本体70Aに取り付けられ、係合軸部82aが回転体71Aに係合される構成である。これに対し、図16のユニット品90は実用新案登録第2592758号に開示のもので、筒部材85に対し回動不能に挿通されて両端部85a側を突出している軸部材86と、端部85aを筒部87a内に入れた状態で軸部材86に回動可能に組み付けられる両側のブラケット87と、筒部87a内にあって筒内端面と端部85a端面の間の空間Sに配置されてブラケット87を一方向へ回動付勢するばね部材88と、端部85aと筒部87aとの間の隙間に介在されたダンパー用グリス89とからなる。この構造では、筒部材85が回転体71Bの取付部71cに固定され、両ブラケット87が本体70Bに設けられた対応する貫通孔70cに回動不能に係合される。すると、回転体71Bは、本体70B側に設けられて回転体71Bを閉位置に係止するラッチ73を解除操作すると、ばね部材88の付勢力により図16(a)の開位置に回動される。また、従来構造には、特開平9−228715号に開示される如く枢軸及びばね部材とラッチをユニット化したものもある。
【0004】
【発明が解決しようとする課題】
以上のように、従来構造には、枢軸及びダンパーをユニット化したもの、枢軸及びダンパーとばね部材をユニット化したもの、枢軸及びばね部材とラッチをユニット化したものがある。しかし、更に多くの機能部品をユニット化して組立性、部品管理、設計自由度等をより改善したい。その場合には、回動装置ないしはユニット品として、各機能部品が作動特性に優れてコンパクトに収まること、用途に応じた変更も容易であり汎用性に富んでいること、既存の機能部品であってもできるだけ使用可能にして低コスト化を図りやすいこと等がより好ましい。
【0005】
本発明は以上の背景から開発されたものである。その目的は、上記したコンパクト化、汎用性、低コスト化を実現しながら、多機能化を図って適用機器や装置の使い勝手と商品価値の向上に寄与できる回動装置を得ることにある。
【0006】
【課題を解決するための手段】
上記目的を達成するため本発明は、図1〜図14に例示される如く、回転体11を本体10に対し閉位置と開位置に回動可能に枢支する枢軸を有する回動装置1において、前記本体10に取り付けられる略筒形のケース2、及び前記ケース2内に挿入されて回動可能に組み付けられた状態で、前記枢軸に相当する枢軸部31を前記ケースの一端側開口から突出している軸部材3と、前記ケース2内に配置されて前記軸部材3を一方向へ付勢しているばね部材4と、前記ケース2内に配置されて前記回転体11の閉位置方向への押し操作により前記回転体11を閉位置に係止し、当該回転体11の更なる押し操作により前記係止を解除可能なラッチユニット5と、前記軸部材3のうち、前記ケース2内に挿入される軸部分34に串差し状態に配置された制動用のダンパーユニット6とを備えていることを特徴としている。
【0007】
以上の回動装置1は、ケース2が本体10に不動状態に取り付けられ、軸部材3の枢軸部31が回転体11に不動状態に取り付けられる。この状態では、回転体11がばね部材4の付勢力を受けている軸部材3を介し開位置に回動されている。回転体11は、開位置からばね部材4の付勢力に抗して閉位置方向へ押圧操作されると、ラッチユニット5を介し係止されて閉位置に保持される。再び開位置に切り換える場合は、回転体11をばね部材4の付勢力に抗して更に押圧操作すると、前記ラッチユニット5の係止が解除された後、ばね部材4の付勢力によって開位置方向へ回動される。回転体11は、各回動過程において、ダンパーユニット6の制動作用を受けて緩やかに回動される。構造特徴は、軸部材3をケース2内に挿入して回動可能に組み付けると同時に、ばね部材4、ラッチユニット5、ダンパーユニット6をケース2内に内蔵して、付勢作用及びラッチ(ロック)作用とダンパー(制動)作用を具備したユニット品を実現した点にある。ここでのラッチユニット5及びダンパーユニット6は、作動特性の優れた既存のものを適用できる。本発明は、このような多機能化を図ることにより、本体10及び回転体11の設計自由度を拡大し、部品管理や組立性を良好にして構成機器類や各種本体装置の使い勝手を向上できるようにする。
【0008】
以上の本発明は請求項2〜6のように具体化されることがより好ましい。
・第1に、前記ラッチユニット5は、前記軸部材3の回動に連動して軸部材の軸線方向に摺動されるストライカー51、及び前記ケース2に取り付けられて前記回転体11の閉位置方向への押し操作により前記ストライカー51を係止し、当該回転体11の更なる押し操作により前記係止を解除可能なプッシュ・プッシュ係止機構からなる構成である。ラッチユニット5には各種のものがあるが、そのうち、プッシュ・プッシュ係止機構としてはストライカー51を軸部材3の回動に(回転体11の回動とも)連動して摺動されるようにして係脱する構造にすると、ケース2内にコンパクトに収まったり、係止力を増大しやすい利点がある。・第2に、前記ケース2内に配置されて、前記軸部材3と連結されたカム溝54付きのカム部材53を有し、前記ストライカー51が前記カム溝54と嵌合しているピン52を介し摺動される構成である。これは、前記したストライカー51を摺動する構成であり、カム部材53及びピン52を介することにより比較的簡易に実現でき、ケース2内にコンパクトに内蔵できる利点がある。
・第3に、前記ストライカー51は軸部51aの先端に係合突起51bを有し、前記カム部材53は前記ストライカー51の軸部51aを内部に入れる略筒形からなり、前記ピン52は前記ストライカー51の軸部51aに突出されて前記カム溝54を介し前記ケース2内に設けられたガイド溝25に沿って動く構成である。これは、前記ストライカー51及びカム部材53とピン52の関係を特定したもので、ストライカー51を良好に摺動可能にしたり、ケース2内への組み込み性を良好にできる等の利点がある。
・第4に、前記ダンパーユニット6は、ハウジング61及び出力軸62を有し、前記ハウジング61が前記ケース2内に位置固定され、前記出力軸62が前記軸部材3の対応軸部34に位置固定されている構成である。これは、ケース2及び軸部材3とダンパーユニット6の関係を特定したもので、ダンパーユニット6が汎用品であっても、軸部材3とケース2内の形状設定だけで、形態例の如くハウジング61をケース2内に位置固定した状態で、軸部材3の対応軸部34を圧入方式で出力軸62内径に挿入し容易に組み付けることができる等の利点がある。・第5に、前記軸部材3は、一端から他端側に向けて、前記枢軸に相当する枢軸部31、前記ケース2の一端側開口をほぼ閉じる径大軸部32、前記ばね部材4を外周に配置するばね用軸部33、前記ダンパーユニット6を軸装するダンパー用軸部34、前記カム部材53の対応部に連結される連結軸部35とからなる構成である。これは、軸部材3がばね部材4、ダンパーユニット6、カム部材53を直線上に配置可能になっていることにより、ケース2内への組み付け性を良好にしたり、回動装置1のコンパクト化を図りやすくできる等の利点がある。

【0010】
(全体の概要)本発明の回動装置1は、第1形態や第2形態の回動装置1A,1Bとして具体化されて、ケース2、軸部材3、ばね部材4、ラッチユニット5、ダンパーユニット6を必須としている。構造特徴は、ケース2及び軸部材3が樹脂成形品であり、ばね部材4がコイルばねであり、ラッチユニット5がストライカー51を回転体11の押し操作により係止し、次の押し操作により係止解除するプッシュ・プッシュ係止機構からなり、ダンパーユニット6が軸部材3に串差し状態に軸装される公知の流体式制動機構からなり、これらがユニット化されている。また、第1と第2形態は、ケース2以外の構成がほぼ同じくしている。従って、以下の説明では、各形態の同じ部材及び部位に同じ符号を付して、第1形態を主体に述べ、その中で第2形態の変更点を言及することにする。このため、部材説明では、第1形態の対応図面を用いるが、第2形態ではそれに対応する図面に置き換えられることになる。
【0011】
(装置構造)第1形態の回動装置1A(1)は、拡大して図示しているが、全寸が約65〜75mm程度であり、ケース2A(2)内において軸部材3に沿ってばね部材4、ダンパーユニット6、ラッチユニット5の順に配置したユニット品である。これに対し、第2形態の回動装置1B(1)は、全寸が約75〜85mm程度であり、ケース2B内において前記と同様に軸部材3に沿ってばね部材4、ダンパーユニット6、ラッチユニット5の順に配置したユニット品である。
【0012】
第1形態のケース2Aは、一端2aから他端2bまで略同じ外径の筒形となっており、左右が貫通されていると共に、外周に突設されて長手方向に延びている取付孔21a付きのフランジ部21を有している。筒外周には、フランジ部21に加えて、一端2aと近い箇所に設けられて内外を貫通したガイド溝22、及び他端2bと近い箇所に設けられて内外を貫通した対の窓部23と、片側の窓部23の手前に設けられた短直線溝24等を有している。ガイド溝22は、全体が略T形溝状をなし、周囲方向に形成されて軸部材3の回動範囲を規制する円弧溝部22aと、該溝部22aの円弧中間から他端2b側つまり筒軸方向に形成されてばね部材4の対応端を係止する直線溝部22bとからなる。各窓部23は、略矩形窓であり互いに対向していて、後述するプッシュ・プッシュ係止機構56を構成している対応する係止片56を逃がす箇所となる。これに対し、筒内周の概略形状は、図6及び図7において、符号25aで示す箇所つまり一端2aから短直線溝24の少し手前までが同形状、符号25bで示す箇所つまり符号25aの箇所から他端2bの手前までが同形状、他端2bの内径が矩形開口25cとなっている。即ち、符号25bと符号25aの筒内周は相似形であるが、符号25aの最大径L1が符号25bの最大径L2よりも若干大きく設けられ間に段差25dを形成している。筒内周には、一端2aから窓部23の手前まで連続して延びている対の内ガイド溝26と、一端2aから段差25dの少し手前まで連続して延びている単一のダンパー用係止溝27とが設けられている。両内ガイド溝26は略180度変位している。係止溝27は両内ガイド溝26と略90度変位している。
【0013】
これに対し、第2形態のケース2Bは、前記ケース2Aに比べて、他端2bが矩形開口25cより延長された延長筒部25dを有している点と、フランジ部21に代えて筒外周に係止脚部28を形成している点で相違している。延長筒部25dは、図8(a)の如く本体10の配置部10aに設けられる軸部12が回動可能に係合される。軸部12は、専用品を用いて設置部10aに取り付けたり、設置部10aに一体に形成されるものである。係止脚部28は、図12と図9の如く断面が略矩形からなり、弾性係止爪29を対向側面に形成している。弾性係止爪29は、コ形スリットを介し弾性変位可能となっている。
【0014】
軸部材3は、図4と図5の如く一端から他端側に順に設けられた枢軸部31、径大軸部32、ばね用軸部33、ダンパー用軸部34、連結軸部35とからなる。枢軸部31は、軸部材3の一端側に位置し、ケース2Aから突出されて回転体11の係合穴11aに係合結合される枢軸である。径大軸部32は、ケース2Aの一端2aの筒内にほぼ収まる箇所である。径大軸部32の外周には、前後方向に延びた係止溝36と、円弧溝部22aに対応する取付穴37とが設けられている。なお、取付穴37は後述するスプリングピン7を圧入固定する構成であるが、スプリングピン7をねじ止めする構成にしてもよい。軸部33は周囲の一部が欠肉38されている。軸部34は軸部33よりも径小となっており、軸部33の端面に一体化した状態で設けられた対の突起39を有している。連結軸部35は、軸部材3の他端側に位置し、他の部分とは異なって断面矩形に形成されている。
【0015】
ばね部材4は、径大軸部32と軸部33との間の段差に収まる線径のコイルばねであり、軸部33に軸装された状態で、他端4b側が直線溝部22bの奥側に係止され、一端4a側が係止溝36に係止される。
【0016】
ラッチユニット5は、ストライカー51と、ストライカー51を軸部材3の回動に連動して軸線方向に摺動するカム部材53と、ストライカー51を係脱するプッシュ・プッシュ係止機構からなる。ラッチユニット5としては、プッシュ・プッシュ係止機構が汎用品であるが、ストライカー51がカム部材53を介して軸部材3の回動に連動して軸線方向へ摺動されるよう工夫されている。即ち、ストライカー51は、円柱状の軸部51a及び軸部51aの先端に突設された係合突起51bからなる。軸部51aには、中心を通る貫通孔51cが設けられ、ピン52が貫通孔51cに両側から突出した状態に圧入される。このピン52は軸部51aにピン用突起を一体に形成して省略することも可能であり、要は上記した両内ガイド溝26に摺動自在に嵌合するものであればよい。カム部材53は、図4と図5の如く片側を開口した略筒形をなし、一端53a側が前記した段差25dに係合する径大部であり、他端53b側がその径大部より少し径小で長い筒部分となっている。一端53aの端面には、前記した連結軸部35と係合する矩形の連結孔53cが貫通形成されている。他端53bの筒部分には、カム溝54が内外を貫通した状態で設けられている。このカム溝54は、図3の如く前記したピン52の両端が対応部から突出し、該突出状態でカム部材53がピン52の前後動により回動される螺旋状の溝形状となっている。即ち、この構造では、例えば、図3(a)の状態から軸部材3が回動されてカム部材53を同方向へ回動すると、ピン52が螺旋状のカム溝54と、前記した直線溝である内ガイド溝26の両方をトレースして図3(b)の如く図の右側へストライカー51と共に移動可能になっている。
【0017】
プッシュ・プッシュ係止機構は、図3の如くケース2の矩形開口25cに装着される前側を大きく開口したハウジング55、ハウジング55内に収容されて、前記係合突起51bを係脱する対の係止片56を有する摺動体57、摺動体57を一方向に付勢する不図示のスプリング(図1(b)に表れているハウジング55内のスプリング)、摺動体57に設けられたハートカム溝58、ハウジング55内に軸支されたトレーサ59、トレーサ59に突設されてハートカム溝58と係合し摺動体57の摺動によりハートカム溝58を一巡するトレースピン59a等からなる。ハウジング55は、図1や図4の如く前側が一段張り出した張出部55aと両側部に設けられた弾性係止爪55bとを有している。なお、この構造は汎用品であるが、ケース2等に応じて設計することで両係止片56の動きをケース2内に収まるようにしたりハウジング55を小型化して、回動装置1をよりコンパクト化できる。
【0018】
ダンパーユニット6は、図3(a)や図5の如く筒肉厚内に空洞部60aを形成している外筒60と、空洞部60a内に配置される筒形ローター61と、空洞部60a内に一部を挿入してローター61に連結された状態で外筒60の一端に突出している出力軸62と、外筒60の一端側に取り付けられて出力軸62の抜けを防ぐキャップ63と、キャップ63と出力軸62との間及び出力軸62と外筒60との間に装着されて空洞部60a内に充填されるグリスの漏れを防ぐシールリング64a,64bとにより構成されている。外筒60はハウジングであり、外周に突設された係止壁部60bを有している。出力軸62は、空洞部60aから外に出ている筒部分62aが最小径となっていて、筒部分62aの端面に突設された対の規制片部62bを有している。
【0019】
(組立要領)以上の各部材は次の例の如くケース2に組み付けられ回動装置1(1Aや1B)としてユニット化される。即ち、ケース2には、先ず、プッシュ・プッシュ係止機構が組み付けられる。この場合は、ハウジング55がケース2の一端2a側から他端2b側へ両係止片56を縮径しつつ挿入され、後部分が開口25cに押し込められる。すると、ハウジング55は、弾性係止爪55bが開口25c縁に当たって縮径しつつ開口25cを通過しケース2外へ至ったときに復元して、開口25cを形成している箇所を張出部55aと対の弾性係止爪55bとで挟み込んだ状態に取り付けられる。次に、カム部材53がストライカー51をピン51により組み付けた状態でケース2内に挿入される。つまり、カム部材53は、ストライカー51の軸部51aを他端53bの筒部分に入れて、ピン52をカム溝54の一方側溝部から、貫通孔51cに圧入した後、カム溝54の他方側溝部に突出し、ピン52の両端がカム溝54の両側に突出している状態でストライカー51と共にケース2に挿入される。この場合は、カム部材53は、ピン52の両端突出部を内ガイド溝26に沿ってケース2の奥に移動し、径大の一端53aが上記したケース2内の段差25dに当たって規制されるまで押し込むことになる。次に、ダンパーユニット6がケース2内に組み込まれる。この場合、ダンパーユニット6は、ケース2に対し係止壁部60bを一端2a側から前記した係止溝27に沿って挿入されることで回り止めされて位置固定される。次に、ばね部材4がケース2内に入れられる。ばね部材4は、他端4bが直線溝部22bに位置規制された状態に配置され、一端4aが軸部材3のケース2内への組み付け時に付勢圧の発現方向へ捻られつつ係止溝36に係止される。
【0020】
即ち、軸部材3は、連結軸部35側からケース2内に挿入されてばね部材4のコイル内を通過し、ダンパーユニット6の内径(筒部分62a及び外筒60内径に挿通し)を串差し状態に通過する少し手前で、一端4aを係止溝36に係止して略30度程回転しながら、更に押し込んで連結軸部35を連結孔53cに差込係合される。その後、軸部材3は、スプリングピン7がケース2の円弧溝部22aから取付穴37に固定されることでケース2に組み付けられる。回動装置1はこのように容易に組立られる。組立状態において、カム部材53は、段差25dに当接して位置規制された状態で軸部材3の回動に連動して回動される。軸部材3は、筒部分62aに軸部34を圧入していると共に規制片部62b同士の間に突起39を係合し、回動時にはダンパーユニット6の制動力を出力軸62を介し受ける。また、第1形態では、ラッチユニット5のハウジング55の後側がケース2Aから突出している。第2形態では、前記ハウジング55がケース2B内に完全に収まっていて、ケース2の他端2bが延長筒部25dで開口している。
【0021】
(使用態様)以上の回転装置1は、ケース2が本体10に不動状態に取り付けられると共に、軸部材3の枢軸部31が回転体11に不動状態に取り付けられる。ここで、本体10は、各種の機器類や収納装置のハウジングであり、回動装置1A,1Bを配置する配置部10aが各ケース2A,2Bに対応して設けられる。回転体11は、本体10の開口部を開閉する扉やリッド等であり、軸部材3の枢軸部31が係合される係合穴11aが設けられる。即ち、本体10及び回転体11は、例えば、図15(a)の様な機器等の本体70A及び回転体71Aであったり、図16(a)の様な収納装置等の本体70B及び回転体71Bを想定している。そして、第1形態の回動装置1Aにおいては、図2の如く前記フランジ部21が設置部10aに位置決め配置された後、ねじ等の止め部材8を用いて取り付けられる。回転体11は、枢軸部31が係合穴11aに係合結合されて枢軸部31を支点として回動可能に保持される。なお、回転体11は、通常、一方側が係合穴11aと枢軸部31との結合関係にあり、他方側が本体10側の対応部との間で図1の如く軸部13を介し回動可能に連結される。これに対し、第2形態の回動装置1Bは、係止脚部28が設置部10aに設けられる係合穴に対し押し込め方式で挿入されて弾性係止爪29を介し取り付けられる。回転体11は、枢軸部31が係合穴11aに係合結合されて枢軸部31を支点として回動可能に保持される。回転体11は、一方側が係合穴11aと枢軸部31との結合関係にあり、他方側が本体10側の軸部12が延長筒部25dと回動自在に嵌合している。また、各形態例では、回転体11の回動角Zが本体10(開口部等)に対し約120度回動される例である。但し、回転体11の回動角Zは、円弧溝部22aやカム溝54等を少し変えるだけで適宜に変更可能である。
【0022】
(作動)以上の回動装置1は、回転体11がばね部材4の付勢力によって開位置へ移動しており、該開位置からばね部材4の付勢力に抗し押し操作されて本体10の閉位置(本体10の開口部を閉じた位置等)にラッチユニット5を介し保持される。即ち、作動的には、回転体11の閉位置方向への回動操作によりストライカー51が上記した軸部材3、カム部材54、ピン52の関係でハウジング55側へ摺動されて、係合突起51bが摺動体57に突き当たり、図3や図10の(b)の如く上記した不図示のスプリングの付勢力に抗して該摺動体57をハウジング55の奥へ摺動する。これと連動して、両係止片56はハウジング55内に引き込まれつつ係合突起51bを間に挟み込む。同時に、トレースピン59aとハートカム溝58との係合によって対の係止片56が後退位置で係止されて、回転体11を閉位置に保持する。この係止を解除するには、回転体11を更に閉位置方向へ押し操作することにより、図3や図10の(a)の如くトレースピン59aとハートカム溝58との係合が外れ、同時に摺動体57が前記スプリングの付勢力により押されて、両係止片56をハウジング55前方へ突出する。この結果、係合突起51bは、両係止片56による挟み込みから外れて係止状態が解除される。このような係止機構を採用すると、ケース2への組み付け性がよく、ケース2内におけるストライカー51との位置関係を少ないスペースで確保できる。そして、回転体11は、各回動時において、ケース2内のダンパーユニット6の制動作用を軸部材3を介し受けて緩やかに回動される。このような構造では、ばね部材4及びダンパーユニット6とラッチユニット5がケース2内に直列に配置されるため、ケース2内にコンパクトに収まると共に軸部材3との関係も確実かつ容易に得られる。また、回動装置1は、各形態例から分かる如く、ケース2だけを変更するだけで用途に応じた全く異なる外形状のものとして製作されるため、汎用性に優れている。
【0023】
なお、本発明は請求項1に記載の技術要素を除いて、上記各形態を基にして必要に応じ変形可能なものである。その一例としては、第1形態と第2形態の本体10への取付構造を逆にしたり、それ以外の取付構造を採用することである。
【0024】
【発明の効果】
以上説明したように、本発明の回動装置は、枢軸部を形成している軸部材と共にばね部材及びラッチユニットとダンパーユニットをケース内に内蔵してユニット化されており、従来品に比べて多機能化を図って適用機器や装置の使い勝手と商品価値の向上に寄与できる。
