Description

【０００１】
【発明の属する技術分野】
本発明は、グリル庫内で魚等の被調理物を加熱調理するグリルに設けられたグリル扉の開閉装置に関する。
【０００２】
【従来の技術】
従来より、ガステーブルこんろにおいては、中央部に魚等の被調理物を加熱調理できるグリルを備え、被調理物を焼網に載せたまま受皿を手前にスライドさせると、それに伴いグリルの扉が自動的に上に跳ね上がり扉がじゃまにならず容易に被調理物を取り出すことができるタイプのものが知られている。
例えば、このようなグリルとしては、図１０，図１１，図１２に示すようなものが知られている。このグリル１０１は、被調理物を載せる焼網２と、焼網２を載せたまま手前にスライドさせて引出す受皿３と、ガスを燃焼させて被調理物を加熱するバーナ４と、これらを収めるグリル庫５等から構成される。グリル庫５は、その前面開口側壁７にグリル扉８を備える。また、受皿３の前部には、取手９が取付板１０を介して一体に固定されている。
グリル扉８の内側には、略Ｌ字状の連結部１１が両サイドに固定され、連結部１１の一端には連結部１１の回動支点となる支軸１２が、他端には軸孔１３が設けられる。支軸１２は、前面開口側壁７に軸止され、軸孔１３には、受皿３の進退動作とグリル扉８の開閉動作とを連動させる略くの字状の連動腕１４の先端部が挿通される。連動腕１４は、その先端部に球状の突起が外側面に設けられ、この突起が軸孔１３に挿通されることで連結部１１に回動可能に連結される。また、連結腕１４の基端部は下方に向けて曲折される。
【０００３】
グリル庫５の左右両側壁５ｂの後方下部には、受皿３の進退移動方向に延びる長溝孔１６が開設され、左右の長溝孔１６に受皿３の奥行壁外面に当接される連結バー１７の両端部が遊挿される。この連結バー１７の両端部は、グリル庫５の左右の側壁５ｂの外側に設けられた連結腕１４の基端部にそれぞれ挿通され連結される。
さらに連結バー１７の両端部にそれぞれ一端を止着した引っ張りバネ１８の他端をグリル庫側壁５ｂの手前部に突設した掛止ピン１９に係止させることにより、連動腕１４と連結バー１７とは常時受皿３の前進方向（手前側方向）へ押出付勢されている。グリル庫５入口の底壁５ａには、引っ張りバネ１８の付勢力により受皿３が手前に飛び出すのを規制し収納位置を確定する突起状のストッパー２０が設けられる。
引っ張りバネ１８は、受皿３が手前に引き出されグリル扉８を支軸１２を回転の支点として上方向へ跳ね上げた時、グリル扉８が下方向へ戻って閉じてしまうのを防ぎそのまま保持するだけの力が必要である。そのため、受皿３が所定位置まで引き出された地点で、所定力（グリル扉８の自重による荷重力以上）付勢しているように設計される。
こうした構成により、受皿３は、底壁５ａに沿ってスライドし、それに伴ってグリル扉８が自動的に開閉するので、被調理物のグリル庫５への出し入れが容易にできるというものである。
【０００４】
【発明が解決しようとする課題】
しかしながら、一旦、受皿３にストッパー２０の係止力に打ち勝つだけの力を与えて収納位置から手前にすばやく引き出すと、グリル扉８が引っ張りバネ１８によって跳ね上げ方向に付勢されているので、グリル扉８は、勢い良く跳ね上がってしまい、器具本体と衝突して不快な衝突音を発生し使用感が悪いといった問題があった。
本発明のグリルは上記課題を解決し、グリル扉を開ける時に不快な衝突音が生じるのを防止して、使用感を良くすることを目的とする。
【０００５】
【課題を解決するための手段】
上記課題を解決する本発明の請求項１記載のグリルは、
グリル庫の前面開口に設けられ支軸を支点として上下方向に回動して片開き状に開閉するグリル扉と、該グリル庫内を進退方向にスライドして該グリル庫に出し入れする受皿と、該受皿の進退動作と該グリル扉の開閉動作とを連動させる連結部材と、該グリル扉を開方向に付勢する付勢手段と、上記グリル扉の開方向への回動速度を遅らせる速度調節装置とを有し、該グリル扉の閉状態からの開方向への回動初期においては、該速度調節装置が動作しないようにしたグリル扉の開閉装置を有するグリルにおいて、
上記速度調節装置は、先端に傘状の弾性体を備えたピストンとシリンダーとで構成され、該シリンダーの該ピストンで区画される少なくとも一室側を密閉構造とすると共に、該ピストンが摺動するのにともない流体が該密閉構造とした一室からの流入出を制限する細孔を備えており、
上記ピストンの軸には、上記グリル扉の閉状態からの開方向への回動初期において上記連結部材が所定ストローク移動したところで該連結部材と係合する係合部材が設けられ、
上記連結部材と上記係合部材とが係合することにより、上記付勢手段による上記グリル扉の開方向への付勢力に対して抵抗を与えるように、上記ピストンの動きが連動させられることを要旨とする。
【０００６】
また、本発明の請求項２記載のグリルは、上記請求項１記載のグリルにおいて、
上記速度調節装置は、上記グリル扉の閉方向への回動動作に比べて開方向への回動動作に対して大きい制動力を与えることを要旨とする。
【０００７】
また、本発明の請求項３記載のグリルは、
グリル庫の前面開口に設けられ支軸を支点として上下方向に回動して片開き状に開閉するグリル扉と、該グリル庫内を進退方向にスライドして該グリル庫に出し入れする受皿と、該受皿の進退動作と該グリル扉の開閉動作とを連動させる連結部材と、該グリル扉を開方向に付勢する付勢手段と、上記グリル扉の開方向への回動速度を遅らせる速度調節装置とを有し、該グリル扉の閉状態からの開方向への回動初期においては、該速度調節装置が動作しないようにしたグリル扉の開閉装置を有するグリルにおいて、
上記速度調節装置は、筒体と該筒体内を摺動するスピンドルとにより構成され、該筒体と該スピンドルとの摺動面に粘着用グリスを塗布しており、
上記スピンドルには、上記グリル扉の閉状態からの開方向への回動初期において上記連結部材が所定ストローク移動したところで該連結部材と係合する係合部材が設けられ、
上記連結部材と上記係合部材とが係合することにより、上記付勢手段による上記グリル扉の開方向への付勢力に対して抵抗を与えるように、上記スピンドルの動きが連動させられることを要旨とする。
【０００９】
上記構成を有する本発明の請求項１記載のグリルは、受皿をスライドさせてグリル庫より出し入れする際、受皿のスライドに連動して連結部材がグリル扉を開閉する。しかも、付勢手段がグリル扉を開方向に付勢しているため、グリル扉は、グリル皿の動きに同調して自動的に開放される。この際、受皿をすばやく引き出すと、グリル扉は、開方向に付勢されているために勢い良く回動しようとするが、速度調節装置が開方向への回動速度を遅らせるので、グリル扉はゆっくりと開く。このため、グリル扉が勢い良く開方向に回動して器具本体に衝突してしまうことを防止できるので、不快な衝突音が発生することはない。
【００１０】
ところで、速度調節装置によってグリル扉の開方向への回動速度があまりに遅らされたり、受皿をすばやく引き出そうとすると、グリル扉がまだグリル庫の前面開口を閉じている状態で、受皿が前面開口に到達してしまい受皿や受皿の上に載置される被調理物がグリル扉と衝突するおそれがある。
そこで、本発明では、グリル扉の開方向への回動初期においては、速度調節装置を動作させず、グリル扉をすばやく回動させることにより、受皿をすばやく引き出しても上述したような不具合が生じないようにしている。
【００１１】
しかも、本発明の請求項１記載のグリルは、先端の傘状の弾性体が開く方向にピストンをシリンダー内で動かそうとすると、傘状の弾性体が開いて弾性体とシリンダーの内面が密着し、シリンダーとピストンとで区画される少なくとも一室側が密閉構造であるために、この密閉構造とした一室からは、細孔を介してしか流体は流入出できないのでピストンの動きに対して大きな抵抗が生じる。この抵抗は、流体の流入出を制限する細孔の面積によって決まる。従って、グリル扉を開方向に付勢する付勢手段の付勢力に対して抵抗を与えるように、傘状の弾性体が開く方向のピストンの動きを連動させておくと、ピストンを動かすための抵抗により、グリル扉は、ゆっくりと開く。よって、グリル扉が器具本体にぶつかることによる不快な衝突音の発生を防止できる。この時のグリル扉の回動速度は、ピストンを動かすための抵抗、すなわち細孔の面積によって決まる。しかも、ピストンは、連結部材と係合部材とが係合した後にしか動かないので、連結部材と係合部材とが係合する前、すなわちグリル扉の閉状態からの開方向への回動初期においては、グリル扉をすばやく回動させることができる。また、傘状の弾性体が閉まる方向にピストンを動かす場合には、流体は細孔だけではなく、弾性体とシリンダーとの間も通って流れるために、ピストンを動かすための抵抗はほとんど生じないので、グリル扉の閉方向への回動はスムーズにすばやく行うことができる。
【００１２】
また、本発明の請求項２記載のグリルは、速度調節装置がグリル扉の閉方向への回動動作に対しては、制動力を与えないあるいは小さな制動力しか与えないので、グリル扉の閉方向への回動をスムーズにすばやく行うことができる。
【００１３】
また、本発明の請求項３記載のグリルは、筒体とスピンドルとの摺動面に粘着用グリスが塗布されており、その粘着性によって筒体とスピンドルとの間の抵抗が増すので、グリル扉を開方向に付勢する付勢手段の付勢力に対して抵抗を与えるように、スピンドルの動きを連動させておくと、その大きな抵抗によって、グリル扉は、ゆっくりとしか開かない。よって、グリル扉が器具本体にぶつかることによる不快な衝突音の発生を防止できる。しかも、スピンドルは、連結部材と係合部材とが係合した後にしか動かないので、連結部材と係合部材とが係合する前、すなわちグリル扉の閉状態からの開方向への回動初期においては、グリル扉をすばやく回動させることができる。
【００１４】
【発明の実施の形態】
以上説明した本発明の構成・作用を一層明らかにするために、以下本発明のグリルの好適な実施形態について図１〜図９を用いて説明する。図１〜図４は、本実施形態のグリルの概略構成図であり、図１はグリル扉が閉状態のときの側面図、図２はグリル扉が所定角度だけ開いたときの側面図、図３はグリル扉が全開状態のときの側面図、図４は上面図である。
尚、本実施形態のグリル１は、先に説明した従来のグリル１０１とは、グリル扉８の開方向への回動速度を遅らせる速度調節装置３０を設けた点のみが異なるので、重複を避けるため、同一部分の構成については同一符号を付し詳しい説明は省略する。
【００１５】
グリル１のグリル扉８の内側には、略Ｌ字状の連結部１１が両サイドに固定され、連結部１１の一端には連結部１１の回動支点となる支軸１２が設けられる。この支軸１２は、前面開口側壁７に軸止されており、グリル扉８は、支軸１２を支点として上下方向へ片開き状に一定の角度だけ回動できるようになっている。尚、図１に示すように、グリル扉８の全閉時（受皿３の収納時）には、グリル扉８の下端部が前記取手９に設けた突板２１に係合されてグリル庫５の前面開口２２を隙間のないよう確実に閉塞し、図３に示すように、グリル扉８の全開時（受皿３の引き出し時）にはその係合が外れてグリル扉８の開放が何ら支障なく行えるようになっている。
【００１６】
連結部１１の他端には、軸孔１３が設けられ、この軸孔１３には、受皿３の進退動作とグリル扉８の開閉動作とを連動させる略くの字状の連動腕１４の先端部が挿通される。連動腕１４は、その先端部に球状の突起が外側面に設けられ、この突起が軸孔１３に挿通されることで連結部１１に回動可能に連結される。また、連結腕１４の基端部は下方に向けて曲折される。
そして、グリル庫５の左右両側壁５ｂの後方下部には、受皿３の進退移動方向に延びる長溝孔１６が開設され、左右の長溝孔１６に受皿３の奥行壁外面に当接される連結バー１７の両端部が遊挿される。この連結バー１７の両端部は、グリル庫５の左右の側壁５ｂの外側に設けられた連結腕１４の基端部にそれぞれ挿通され連結される。
さらに連結バー１７の両端部にそれぞれ一端を止着した引っ張りバネ１８の他端をグリル庫側壁５ｂの手前部に突設した掛止ピン１９に係止させることにより、連動腕１４と連結バー１７とは常時受皿３の前進方向へ押出付勢されている。
また、グリル庫５入口の底壁５ａには、引っ張りバネ１８の付勢力により受皿３が収納状態から手前に飛び出すことを規制し収納位置を確定する突起状のストッパー２０が設けられる。
【００１７】
連結バー１７の片方の端部には、グリル扉８の開方向への回動速度を遅らせる速度調節装置３０（後述）のピストン３１の軸を進退作動させるＬ字状の進退板４１が取り付けられる。連結バー１７は、進退板４１と連動腕１４を重ね合わせて挿通する。そして、進退板４１と連動腕１４の左右両側から止具で挟みこむことにより、進退板４１と連結腕１４とは連結バー１７と固定される。
そして、ピストン３１の軸の基端部及び基端部から所定距離離れた部位には、図５に示すように、円盤状の基端止片３１ａ及び中間止片３１ｂが設けられる。進退板４１は、一辺を連結バー１７に固定され、もう一辺にピストン３１の軸を貫通させるための横長な切込部４１ａが設けられる。そして、ピストン３１の軸は、基端止片３１ａと中間止片３１ｂとの間の基端軸部３１ｃが、横方向から切込部４１ａに挿入される。ピストン３１の軸と進退板４１とは固着されるものではなく、切込部４１ａの縦方向の長さはピストン３１の軸の直径よりも若干大きめに形成されているので、進退板４１は基端止片３１ａと中間止片３１ｂとの間で自由な位置を取ることができる。
また、速度調節装置３０は、グリル庫５の底壁５ａに設けられた止壁４４にネジ止めすることにより、グリル庫５内に固定される。
【００１８】
以下、速度調節装置３０について詳述する。
図６に示すように、速度調節装置３０は、ピストン３１とシリンダー３２とを備える。ピストン３１の先端は、傘状のゴム体３３であり、ピストン３１の軸の先端には、シリンダー３２のピストン３１で区画される両室間を連通するオリフィス３４が設けられる。シリンダー３２の先端には、Ｏリング３７を介して蓋体３６が嵌め込まれ、この蓋体３６とゴム体３３との間に密閉室３５が形成される。
シリンダー３２の基端には、中心にピストン３１の軸より少し大きな軸穴３９が開口された軸枠４０が、その軸穴３９にピストン３１の軸を貫通させて嵌め込まれ軸枠４０とゴム体３３との間に開放室３８が形成される。このため、ピストン３１の軸の動きは、図面中の左右の直線方向のみに規制される。尚、ピストン３１の軸は、中間止片３１ｂよりも先端側で軸穴３９に挿通される。
【００１９】
次に、この速度調節装置３０の作動原理について説明する。
ピストン３１を図左方向に動かす場合、ピストン３１の先端の傘状のゴム体３３が左に動くと傘が開いてシリンダー３２の内壁面と密着するため、密閉室３５と開放室３８間を空気は、軸に設けたオリフィス３４を介してのみしか通過できないので、ピストン３１の左方向の動きに対しては大きな抵抗が生じる。また、この時の抵抗は、オリフィス３４径によって決められるものである。
従って、ピストン３１に取り付けられた連動腕１４を介して引っ張りバネ１８の復元力によりピストン３１を左方向に動かそうとすると、この大きな抵抗のために引っ張りバネ１８の弾性変形は、ゆっくりとしか元の形に戻れず、連動腕１４もゆっくりとしか動かない。
【００２０】
一方、ピストン３１を図右方向に動かす場合、傘状のゴム体３３が図右に動くと傘が閉じてシリンダー３２の内壁面とゴム体３３との間にすきまができる。このため、密閉室３５と開放室３８間を空気は、このすきまを通って自由に通過することができるため、ピストン３１が右に動く場合にはほとんど抵抗は生じない。従って、ピストン３１に取り付けられた連動腕１４を介してピストン３１を右側へ移動させようとする場合には、特別な抵抗を感じることなくスムーズに移動させることができる。
また、グリル扉８が閉まっているときは、図１に示すように、進退板４１が中間止片３１ｂと接している状態であり、グリル扉８が開いているときは、図３に示すように、進退板４１が基端止片３１ａと接している状態となるように速度調節装置３０は設けられる。
【００２１】
このように構成されたグリル１によれば、取手９を握って受皿３をグリル庫５より引き出すとき（図１→図２→図３）には、引っ張りバネ１８により手前側方向に付勢されている連結バー１７が受皿３と共に長溝孔１６内を所定ストロークだけ前進し、連動腕１４も前進動してグリル扉８を全開位置までもっていく。この際、受皿３をすばやく引き出すと、グリル扉８が連動腕１４を介して引っ張りバネ１８の復元力で開方向に付勢されているために、グリル扉８は勢い良く回動しようとする。
ところが、連動腕１４に速度調節装置３０のピストン３１が取り付けられ、図左方向の動きに対しては途中から大きな抵抗がかかるので、引っ張りバネ１８はゆっくりとしか弾性変形できず、連結バー１７が引き出し速度に追従できないためにグリル扉８もゆっくりとしか回動しない。
【００２２】
連動腕１４が一番奥（図右方向）に位置している状態（図１）、すなわちグリル扉８の閉状態から、手前（図左方向）に動き出す初期段階（図１→図２）では、進退板４１が中間止片３１ｂと基端止片３１ａとの間（いわゆる、遊びのストローク）を移動するだけであるからピストン３１は動かず、速度調節装置３０も機能しない。このため、グリル扉８回動初期においては、グリル扉８はすばやく回動する。
そして、進退板４１が基端止片３１ａと接した後に、さらに手前に動こうとすると（図２→図３）、進退板４１によって基端止片３１ａが押される、すなわちピストン３１が図左方向に押されることになり、速度調節装置３０が機能する。言い替えれば、グリル扉８が閉状態から所定角度θ（好ましくは２０°〜２５°）回動するまでは、速度調節装置３０による制動力がグリル扉８の開動作、すなわち、連動腕１４を介しての引っ張りバネ１８の復元力には加わらない。そして、グリル扉８はそのまま開動作し、所定角度θまで開くと進退板４１が基端止片３１ａに当接して、その後は速度調節装置３０による制動力が加わる。
【００２３】
このため、グリル扉８は開方向への回動の途中からはゆっくりとしか回動せず、勢い良く開くことはない。従って、グリル扉８と器具本体が衝突して不快な衝突音が生じることを防止できる。しかも、回動初期においては、速度調節装置３０が動作しないので、すばやく回動させることができる。このため、受皿３をすばやく引き出しても、受皿３や被調理物がグリル扉８と接触することを防止でき、受皿３をスムーズに取りだすことができる。
【００２４】
逆に、取手９をにぎって受皿３をグリル庫５内へ収める時（図３→図１）には、受皿３がグリル庫５内へ送入されていく途中でこの受皿３の奥行壁面に連結バー１７が当接し、その後一体となって引っ張りバネ１８の付勢力に抗して後退させられるので、その連結バー１７の後退動に伴って連動腕１４も後退動する。このためにグリル扉８は支軸１２を支点として回動し、受皿３がグリル庫５内に収められると同時にグリル扉８もグリル庫５の開口部に閉じられる。
このとき、連動腕１４に取り付けられた速度調節装置３０のピストン３１も図右方向に動かされるが、右方向に動く場合は、ほとんど抵抗が生じないので、受皿３を収納するのに対して余分な力を必要とせず従来通りスムーズに行うことができ使い勝手が良い。言い替えれば、グリル扉８の閉方向への回動に対しては、制動力は非常に小さい。尚、グリル扉８の閉方向への回動初期においては、進退板４１が基端止片３１ａから中間止片３１ｂの間を動きピストン３１が動かないので、受皿３を収納するのに対して余分な力を全く必要としない。
また、受皿３がグリル庫５内の所定位置に収納されると、受皿３はその前面壁がストッパー２０により係止され、不用意な抜脱が規制された状態でグリル庫５内に納められる。
【００２５】
以上本発明の実施形態について説明したが、本発明はこうした実施形態に何等限定されるものではなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。
例えば、本実施形態の速度調節装置３０では、ピストン３１の軸の先端にオリフィス３４を設けて密閉室３５内の空気が移動できるようにしているが、図７に示すように、オリフィス３４を設けずに蓋体３６に細孔４３を設けるような構成にしても構わない。この場合にも、ピストン３１を図左方向に動かす際には、密閉室３５内へは、空気は細孔４３を介してしか移動できないために、ピストン３１を左方向に動かす抵抗が増すので、グリル扉８が勢い良く開方向に回動することを防止できる。ピストン３１を右方向に動かす際には、密閉室３５内の空気は、シリンダー３２の内壁面とゴム体３３のすきまを介しても移動することができるため、ピストン３１が右に動く場合にはほとんど抵抗を生じない。
また、図８に示すように、オリフィス３４と細孔４３とを両方同時に設けておいても構わない。この場合にも、ピストン３１を左側に動かす際には、密閉室３５内へは、空気はオリフィス３４と細孔４３を介してしか移動できないので大きな抵抗がかかり、ピストン３１を右側に動かす際には、密閉室３５内の空気はシリンダー３２の内壁面とゴム体３３のすきまを介しても移動することができるのでほとんど抵抗は生じない。
【００２６】
また、本実施形態では、速度調節装置３０をシリンダー３２とピストン３１により構成したが、図９に示すように、筒体５１とその筒体５１内を摺動するスピンドル５２とによって構成して、その摺動面５３に粘着用グリスを塗布したものであってもかまわない。
この場合には、粘着用グリスの粘着性によって筒体５１とスピンドル５２との間の抵抗が増すので、連動腕１４にピストン３１を取り付けたのと同様な方法で連動腕１４にスピンドル５２を取り付ければ、連動腕１４の進退移動に対する抵抗が増すので、引っ張りバネ１８がゆっくりと弾性変形するために、グリル扉８が勢い良く開方向に回動することを防止でき、不快な衝突音が生じることを防ぐことができると共に、回動初期においてはすばやく回動させることができ、受皿３や被調理物がグリル扉８と接触することを防止できるので、受皿３をスムーズに取りだすことができる。
【００２７】
【発明の効果】
以上詳述したように、本発明の請求項１記載のグリルによれば、グリル扉は、付勢手段の付勢力によって勢い良く回動して開こうとするが、速度調節装置が開方向への回動速度を遅らせるので、グリル扉はゆっくりと開く。このため、グリル扉が勢い良く開方向に回動して器具本体に衝突してしまうことを防止できるので、不快な衝突音が発生することがなくなり使用感が向上する。
しかも、グリル扉の開方向への回動初期においては、速度調節装置が動作しないので、グリル扉は所定角度まですばやく回動するため、受皿をすばやく引き出しても、グリル扉が受皿や調理物に当たってしまうという不具合もなく、受皿をスムーズに引き出すことができる。
また、本発明の請求項１記載のグリルによれば、ピストンとシリンダーという簡単な構成で安価に速度調節装置を作製することができるので、製造コストを抑えることができる。
【００２８】
また、本発明の請求項２記載のグリルによれば、受皿を収納するのに対して余分な力を必要とせず従来通りスムーズに行うことができ使い勝手が良い。
【００２９】
また、本発明の請求項３記載のグリルによれば、筒体とスピンドルという簡単な構成で安価に速度調節装置を作製することができるので、製造コストを抑えることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing device for a grill door provided in a grill for heating and cooking an object to be cooked such as a fish in a grill cabinet.
[0002]
[Prior art]
Conventionally, a gas table stove has a grill that can cook food such as fish in the center, and when the food pan is slid to the front with the food being placed on the grill, the grill door is accordingly moved. There is a type that automatically jumps up and can easily take out the food without disturbing the door.
For example, as such a grill, what is shown in Drawing 10, Drawing 11, and Drawing 12 is known. The grill 101 accommodates the grill 2 for placing the food to be cooked, the receiving tray 3 that is slid forward while the grill 2 is placed, the burner 4 that heats the food by burning gas. It consists of a grill cabinet 5 and the like. The grill cabinet 5 includes a grill door 8 on the front opening side wall 7 thereof. A handle 9 is integrally fixed to the front portion of the tray 3 via a mounting plate 10.
A substantially L-shaped connecting portion 11 is fixed to both sides inside the grill door 8, a support shaft 12 serving as a pivot for the connecting portion 11 is provided at one end of the connecting portion 11, and a shaft hole is provided at the other end. 13 is provided. The support shaft 12 is pivotally fixed to the front opening side wall 7, and the distal end portion of a generally U-shaped interlocking arm 14 that interlocks the advancing / retreating operation of the tray 3 and the opening / closing operation of the grill door 8 is inserted into the shaft hole 13. Is done. The interlocking arm 14 is provided with a spherical protrusion on the outer surface at the tip thereof, and the protrusion is inserted into the shaft hole 13 so as to be rotatably connected to the connecting part 11. Further, the base end portion of the connecting arm 14 is bent downward.
[0003]
Long groove holes 16 extending in the advancing and retreating direction of the tray 3 are formed in the lower rear portions of the left and right side walls 5b of the grill cabinet 5, and the connecting bar 17 that abuts the outer wall of the depth wall of the tray 3 in the left and right long groove holes 16 is provided. Both ends are loosely inserted. Both end portions of the connecting bar 17 are inserted and connected to base end portions of connecting arms 14 provided on the outer sides of the left and right side walls 5b of the grill cabinet 5, respectively.
Further, the other end of the tension spring 18 that has one end fixed to both ends of the connecting bar 17 is engaged with a latching pin 19 protruding from the front side of the grill cabinet side wall 5b, whereby the interlocking arm 14 and the connecting bar 17 are connected. Is constantly pushed in the forward direction (front direction) of the tray 3. The bottom wall 5a at the entrance of the grill cabinet 5 is provided with a protruding stopper 20 that restricts the tray 3 from jumping forward by the urging force of the tension spring 18 and determines the storage position.
The tension spring 18 prevents the grill door 8 from returning downward and closing when the tray 3 is pulled forward and the grill door 8 is flipped upward with the support shaft 12 as a fulcrum of rotation. Only the power is needed. Therefore, it is designed such that a predetermined force (more than the load force due to the weight of the grill door 8) is urged at a point where the tray 3 is pulled out to a predetermined position.
With such a configuration, the tray 3 slides along the bottom wall 5a, and the grill door 8 automatically opens and closes accordingly, so that the food to be cooked can be easily put in and out of the grill cabinet 5.
[0004]
[Problems to be solved by the invention]
However, once the grill door 8 is urged in the flip-up direction by the tension spring 18 when the tray 3 is given a force that overcomes the locking force of the stopper 20 and is quickly pulled forward from the storage position, There was a problem that the door 8 jumped up vigorously, collided with the main body of the instrument and generated an unpleasant collision sound, and the usability was poor.
The grill of the present invention solves the above-mentioned problems and aims to improve the feeling of use by preventing unpleasant collision noises when the grill door is opened.
[0005]
[Means for Solving the Problems]
The grill according to claim 1 of the present invention that solves the above problems is provided.
A grill door that is provided at the front opening of the grill cabinet and pivots up and down around a support shaft to open and close in a single-opening manner; a tray that slides in and out of the grill cabinet in and out of the grill cabinet; A connecting member that interlocks the advancing / retracting operation of the tray and the opening / closing operation of the grill door, a biasing means that biases the grill door in the opening direction, and a speed adjustment that delays the rotation speed of the grill door in the opening direction. A grill door having an opening / closing device for the grill door in which the speed adjusting device is not operated at an initial rotation in the opening direction from the closed state of the grill door.
The speed adjusting device is composed of a piston and a cylinder having an umbrella-like elastic body at the tip, and at least one chamber side defined by the piston of the cylinder has a sealed structure, and the piston slides. The fluid is provided with pores that restrict inflow and outflow from the one chamber having the sealed structure.
The piston shaft is provided with an engaging member that engages with the connecting member when the connecting member moves a predetermined stroke in the initial rotation of the grill door from the closed state to the opening direction.
By engaging the connecting member and the engaging member, the movement of the piston is interlocked so as to provide resistance against the biasing force of the biasing means in the opening direction of the grill door. The gist.
[0006]
A grill according to claim 2 of the present invention is the grill according to claim 1,
The gist of the speed adjusting device is that it gives a larger braking force to the turning operation in the opening direction than the turning operation of the grill door in the closing direction.
[0007]
A grill according to claim 3 of the present invention is
A grill door that is provided at the front opening of the grill cabinet and pivots up and down around a support shaft to open and close in a single-opening manner; a tray that slides in and out of the grill cabinet in and out of the grill cabinet; A connecting member that interlocks the advancing / retracting operation of the tray and the opening / closing operation of the grill door, a biasing means that biases the grill door in the opening direction, and a speed adjustment that delays the rotation speed of the grill door in the opening direction. A grill door having an opening / closing device for the grill door in which the speed adjusting device is not operated at an initial rotation in the opening direction from the closed state of the grill door.
The speed adjusting device is composed of a cylindrical body and a spindle that slides within the cylindrical body, and is applied with adhesive grease on a sliding surface of the cylindrical body and the spindle,
The spindle is provided with an engaging member that engages with the connecting member when the connecting member moves a predetermined stroke in the initial rotation in the opening direction from the closed state of the grill door,
When the coupling member and the engagement member are engaged , the movement of the spindle is interlocked so as to provide resistance to the urging force in the opening direction of the grill door by the urging means. The gist.
[0009]
In the grill according to the first aspect of the present invention having the above-described configuration, the connecting member opens and closes the grill door in conjunction with the slide of the saucer when the saucer is slid and put in and out of the grill cabinet. Moreover, since the biasing means biases the grill door in the opening direction, the grill door is automatically opened in synchronization with the movement of the grill pan. At this time, when the tray is quickly pulled out, the grill door is urged in the opening direction, so it tries to turn vigorously, but the speed adjusting device delays the rotation speed in the opening direction, so the grill door Open slowly. For this reason, it is possible to prevent the grill door from vigorously rotating in the opening direction and colliding with the instrument body, so that no unpleasant collision sound is generated.
[0010]
By the way, if the speed adjustment device slows down the opening speed of the grill door too much or tries to pull out the saucer quickly, the saucer opens to the front with the grill door still closing the front opening of the grill cabinet. And the object to be cooked placed on the saucer or the saucer may collide with the grill door.
Therefore, in the present invention, at the initial stage of rotation of the grill door in the opening direction, the speed adjusting device is not operated and the grill door is quickly rotated, so that the above-described problems occur even if the tray is quickly pulled out. I am trying not to.
[0011]
Moreover, the grill according to claim 1 of the present invention, when the piston in the direction of the umbrella-like elastic body of the tip is opened to attempt to move in the cylinder, close contact the inner surface of the elastic body and a cylinder umbrella-like elastic member opens However, since at least one chamber side defined by the cylinder and the piston has a sealed structure, fluid can flow in and out only through the pores from the one chamber having the sealed structure. Resistance occurs. This resistance is determined by the area of the pores that limit the inflow and outflow of the fluid. Therefore, if the movement of the piston in the opening direction of the umbrella-like elastic body is interlocked so as to give resistance to the urging force of the urging means for urging the grill door in the opening direction, The grille door opens slowly due to resistance. Therefore, it is possible to prevent an unpleasant collision sound due to the grill door hitting the appliance body. The rotational speed of the grill door at this time is determined by the resistance for moving the piston, that is, the area of the pores. Moreover, since the piston moves only after the connecting member and the engaging member are engaged, the piston is initially rotated before the connecting member and the engaging member are engaged, that is, in the opening direction from the closed state of the grill door. In, the grill door can be quickly rotated. In addition, when moving the piston in the direction in which the umbrella-shaped elastic body closes, the fluid flows not only through the pores but also between the elastic body and the cylinder, so there is almost no resistance to moving the piston. Therefore, the rotation of the grill door in the closing direction can be performed smoothly and quickly.
[0012]
In the grill according to claim 2 of the present invention, the speed adjusting device does not apply a braking force or only a small braking force to the turning operation of the grill door in the closing direction. Rotation in the direction can be performed smoothly and quickly.
[0013]
In the grill according to claim 3 of the present invention, the adhesive grease is applied to the sliding surface between the cylinder and the spindle, and the resistance between the cylinder and the spindle increases due to the adhesiveness. If the movement of the spindle is interlocked so as to resist the urging force of the urging means that urges the door in the opening direction, the grille door opens only slowly due to the large resistance. Therefore, it is possible to prevent an unpleasant collision sound due to the grill door hitting the appliance body. Moreover, since the spindle moves only after the connecting member and the engaging member are engaged, the spindle is initially rotated before the connecting member and the engaging member are engaged, that is, in the opening direction from the closed state of the grill door. In, the grill door can be quickly rotated.
[0014]

[0016]
A shaft hole 13 is provided at the other end of the connecting portion 11, and a tip end of a substantially U-shaped interlocking arm 14 that interlocks the advancing / retreating operation of the tray 3 and the opening / closing operation of the grill door 8 in the shaft hole 13.

Further, the base end portion of the connecting arm 14 is bent downward.
And the long groove hole 16 extended in the back-and-forth movement direction of the saucer 3 is established in the lower rear part of the right-and-left both-side wall 5b of the grill warehouse 5, and the connection bar contact | abutted by the left and right long groove hole 16 at the depth wall outer surface of the saucer 3 Both ends of 17 are loosely inserted. Both end portions of the connecting bar 17 are inserted and connected to base end portions of connecting arms 14 provided on the outer sides of the left and right side walls 5b of the grill cabinet 5, respectively.
Further, the other end of the tension spring 18 that has one end fixed to both ends of the connecting bar 17 is engaged with a latching pin 19 protruding from the front side of the grill cabinet side wall 5b, whereby the interlocking arm 14 and the connecting bar 17 are connected. Is always pushed in the forward direction of the tray 3.
The bottom wall 5a at the entrance of the grill cabinet 5 is provided with a protruding stopper 20 that restricts the receiving tray 3 from jumping out of the stored state by the urging force of the tension spring 18 and determines the storage position.
[0017]
An L-shaped advancing / retracting plate 41 for advancing / retreating the axis of a piston 31 of a speed adjusting device 30 (described later) for delaying the rotational speed of the grill door 8 in the opening direction is attached to one end of the connecting bar 17. . The connecting bar 17 is inserted through the advancing / retreating plate 41 and the interlocking arm 14 in an overlapping manner. Then, the advance / retreat plate 41 and the connecting arm 14 are fixed to the connecting bar 17 by sandwiching the advance / retreat plate 41 and the interlocking arm 14 from both left and right sides with stoppers.
Then, as shown in FIG. 5, a disc-shaped base end stop piece 31a and an intermediate stop piece 31b are provided at a base end portion of the shaft of the piston 31 and a portion away from the base end portion by a predetermined distance. The advancing / retracting plate 41 is fixed to the connecting bar 17 on one side, and is provided with a horizontally long cut portion 41 a for allowing the shaft of the piston 31 to pass through on the other side. And as for the axis | shaft of piston 31, the base end axial part 31c between the base end stop piece 31a and the intermediate | middle stop piece 31b is inserted in the notch part 41a from the horizontal direction. The shaft of the piston 31 and the advance / retreat plate 41 are not fixed, and the longitudinal length of the cut portion 41a is formed slightly larger than the diameter of the shaft of the piston 31, so that the advance / retreat plate 41 is a base. A free position can be taken between the end stop piece 31a and the intermediate stop piece 31b.
Further, the speed adjusting device 30 is fixed in the grill 5 by screwing to a stop wall 44 provided on the bottom wall 5 a of the grill 5.
[0018]
Hereinafter, the speed adjusting device 30 will be described in detail.
As shown in FIG. 6, the speed adjustment device 30 includes a piston 31 and a cylinder 32. The tip of the piston 31 is an umbrella-shaped rubber body 33, and an orifice 34 that communicates between the two chambers defined by the piston 31 of the cylinder 32 is provided at the tip of the shaft of the piston 31. A lid body 36 is fitted at the tip of the cylinder 32 via an O-ring 37, and a sealed chamber 35 is formed between the lid body 36 and the rubber body 33.
A shaft frame 40 having a shaft hole 39 that is slightly larger than the shaft of the piston 31 at the center is fitted at the base end of the cylinder 32 so as to pass through the shaft of the piston 31 in the shaft hole 39. An open chamber 38 is formed between the first and second chambers 33. For this reason, the movement of the shaft of the piston 31 is restricted only in the left and right linear directions in the drawing. The shaft of the piston 31 is inserted through the shaft hole 39 on the tip side of the intermediate stopper piece 31b.
[0019]
Next, the operation principle of the speed adjusting device 30 will be described.
When the piston 31 is moved in the left direction in the figure, when the umbrella-shaped rubber body 33 at the tip of the piston 31 moves to the left, the umbrella opens and comes into close contact with the inner wall surface of the cylinder 32. Can pass only through the orifice 34 provided on the shaft, so that a large resistance is generated against the leftward movement of the piston 31. Further, the resistance at this time is determined by the diameter of the orifice 34.
Therefore, if the piston 31 is moved leftward by the restoring force of the tension spring 18 via the interlocking arm 14 attached to the piston 31, the elastic deformation of the tension spring 18 is only slowly caused by this large resistance. The interlocking arm 14 can only move slowly.
[0020]
On the other hand, when the piston 31 is moved in the right direction in the figure, when the umbrella-shaped rubber body 33 moves to the right in the figure, the umbrella is closed and a gap is formed between the inner wall surface of the cylinder 32 and the rubber body 33. For this reason, since air can freely pass through the gap between the sealed chamber 35 and the open chamber 38, almost no resistance is generated when the piston 31 moves to the right. Therefore, when trying to move the piston 31 to the right side via the interlocking arm 14 attached to the piston 31, it can be moved smoothly without feeling any special resistance.
When the grill door 8 is closed, as shown in FIG. 1, the advancing / retreating plate 41 is in contact with the intermediate stop piece 31b. When the grill door 8 is open, as shown in FIG. In addition, the speed adjusting device 30 is provided so that the advance / retreat plate 41 is in contact with the base end stop piece 31a.
[0021]
According to the grill 1 configured as described above, when the handle 9 is grasped and the tray 3 is pulled out from the grill cabinet 5 (FIG. 1 → FIG. 2 → FIG. 3), it is biased toward the front side by the tension spring 18. The connecting bar 17 is moved forward together with the tray 3 in the long slot 16 by a predetermined stroke, and the interlocking arm 14 is also moved forward to bring the grill door 8 to the fully open position. At this time, when the tray 3 is quickly pulled out, the grill door 8 tends to pivot vigorously because the grill door 8 is biased in the opening direction by the restoring force of the tension spring 18 via the interlocking arm 14.
However, since the piston 31 of the speed adjusting device 30 is attached to the interlocking arm 14 and a large resistance is applied to the movement in the left direction in the figure, the tension spring 18 can be elastically deformed only slowly, and the connecting bar 17 is Since it cannot follow the drawing speed, the grill door 8 also rotates only slowly.
[0022]
In an initial stage (FIG. 1 → FIG. 2) in which the interlocking arm 14 is located at the farthest position (right direction in the figure) (FIG. 1), that is, when the grill door 8 is closed, it starts to move forward (left direction in the figure) Since the advance / retreat plate 41 only moves between the intermediate stop piece 31b and the base end stop piece 31a (so-called play stroke), the piston 31 does not move, and the speed adjusting device 30 does not function. For this reason, at the initial stage of rotation of the grill door 8, the grill door 8 rotates quickly.
When the advance / retreat plate 41 comes into contact with the base end stop piece 31a and then moves further forward (FIG. 2 → FIG. 3), the base end stop piece 31a is pushed by the advance / retreat plate 41. The speed adjusting device 30 functions by being pushed in the direction. In other words, until the grill door 8 is rotated from the closed state by a predetermined angle θ (preferably 20 ° to 25 °), the braking force by the speed adjusting device 30 is opened by the opening operation of the grill door 8, that is, via the interlocking arm 14. It does not apply to the restoring force of all the tension springs 18. The grill door 8 is opened as it is, and when the grill door 8 is opened to a predetermined angle θ, the advancing / retreating plate 41 comes into contact with the base end stop piece 31a, and thereafter the braking force by the speed adjusting device 30 is applied.
[0023]
For this reason, the grill door 8 rotates only slowly from the middle of rotation in the opening direction and does not open vigorously. Therefore, it is possible to prevent the grill door 8 and the instrument body from colliding and generating an unpleasant collision sound. Moreover, since the speed adjusting device 30 does not operate in the initial stage of rotation, it can be quickly rotated. For this reason, even if the saucer 3 is pulled out quickly, the saucer 3 and the object to be cooked can be prevented from coming into contact with the grill door 8, and the saucer 3 can be taken out smoothly.
[0024]
On the other hand, when the tray 9 is put into the grill cabinet 5 with the handle 9 (FIG. 3 → FIG. 1), the tray 3 is placed on the depth wall surface of the tray 3 while being fed into the grill cabinet 5. Since the connecting bar 17 abuts and then is integrally moved back against the urging force of the tension spring 18, the interlocking arm 14 is also moved back as the connecting bar 17 moves backward. For this purpose, the grill door 8 rotates about the support shaft 12 as a fulcrum, and at the same time the tray 3 is stored in the grill cabinet 5, the grill door 8 is also closed at the opening of the grill cabinet 5.
At this time, the piston 31 of the speed adjusting device 30 attached to the interlocking arm 14 is also moved in the right direction in the figure. However, when moving in the right direction, almost no resistance is generated. It is easy to use because it can be performed smoothly as before without requiring extra power. In other words, the braking force is very small for the rotation of the grill door 8 in the closing direction. In the initial rotation of the grill door 8 in the closing direction, the advance / retreat plate 41 moves between the base end stop piece 31a and the intermediate stop piece 31b, and the piston 31 does not move. No extra power is required.
When the tray 3 is stored in a predetermined position in the grill cabinet 5, the front wall of the tray 3 is locked by the stopper 20, and the tray 3 is stored in the grill cabinet 5 in a state where careless removal is restricted.
[0025]
Although the embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
For example, in the speed adjusting device 30 of the present embodiment, the orifice 34 is provided at the tip of the shaft of the piston 31 so that the air in the sealed chamber 35 can move. However, as shown in FIG. Alternatively, the lid 36 may be provided with the pores 43. Also in this case, when the piston 31 is moved in the left direction in the figure, since air can only move into the sealed chamber 35 through the pores 43, the resistance to move the piston 31 in the left direction is increased. It is possible to prevent the grill door 8 from vigorously rotating in the opening direction. When the piston 31 is moved in the right direction, the air in the sealed chamber 35 can also move through the clearance between the inner wall surface of the cylinder 32 and the rubber body 33. Therefore, when the piston 31 moves to the right, Almost no resistance is generated.
Further, as shown in FIG. 8, both the orifice 34 and the pore 43 may be provided at the same time. Also in this case, when the piston 31 is moved to the left side, the air can move only through the orifice 34 and the pore 43 into the sealed chamber 35, so that a large resistance is applied. The air in the sealed chamber 35 can move even through the clearance between the inner wall surface of the cylinder 32 and the rubber body 33, so that almost no resistance is generated.
[0026]
Further, in this embodiment, the speed adjusting device 30 is constituted by the cylinder 32 and the piston 31, but as shown in FIG. 9, it is constituted by a cylinder 51 and a spindle 52 that slides in the cylinder 51, The sliding surface 53 may be coated with adhesive grease.
In this case, since the resistance between the cylinder 51 and the spindle 52 increases due to the adhesiveness of the adhesive grease, the spindle 52 can be attached to the interlocking arm 14 in the same manner as the piston 31 is attached to the interlocking arm 14. In this case, the resistance against the forward / backward movement of the interlocking arm 14 is increased, so that the tension spring 18 is slowly elastically deformed, so that the grill door 8 can be prevented from pivoting in the open direction and an unpleasant collision sound is generated. In addition, the tray 3 can be quickly rotated in the initial stage of rotation, and the tray 3 and the object to be cooked can be prevented from coming into contact with the grill door 8, so that the tray 3 can be smoothly taken out.
[0027]
【The invention's effect】
As described above in detail, according to the grill of the first aspect of the present invention, the grill door is vigorously rotated and opened by the urging force of the urging means, but the speed adjusting device is moved in the opening direction. The grill door opens slowly because the rotation speed of the grill is delayed. For this reason, it is possible to prevent the grill door from vigorously rotating in the opening direction and colliding with the appliance main body, so that an unpleasant collision sound is not generated and the usability is improved.
Moreover, since the speed adjusting device does not operate at the initial stage of turning the grill door in the opening direction, the grill door quickly turns to a predetermined angle, so that even if the saucer is pulled out quickly, the grill door hits the saucer and the food. The tray can be pulled out smoothly without any problems.
Moreover, according to the grill of Claim 1 of this invention, since a speed control apparatus can be produced at low cost with the simple structure of a piston and a cylinder, manufacturing cost can be held down.
[0028]
In addition, according to the grill of the second aspect of the present invention, it is possible to perform smoothly as before without requiring an extra force for storing the tray, and it is easy to use.
[0029]
Further, according to claim 3 Symbol mounting of the grill of the present invention, it is possible to produce inexpensively adjusting speed with a simple structure that the cylindrical body and the spindle, the manufacturing cost can be reduced.
