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、その底壁５ａにガイドレール６と、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の先端部がはめ込まれる。
グリル庫５の奥行き部位の左右両側壁面５ｂ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、この長溝孔１６に上記連動腕１４の基端部が遊挿され、この各連動腕１４の基端部は受皿３の奥行壁外面に当接される連結バー１７の両端部に連結されている。さらにこの連動腕１４の基端部に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）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、ガイドレール６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。
【０００３】
【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。
【０００４】
【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し閉じた状態にあってはグリル庫の前面開口の上半部に位置するグリル扉と、
該グリル庫内を前後方向にスライドして該グリル庫に出し入れされる受皿と、
該受皿の前部に取り付けられ、使用者が上記受け皿をグリル庫に出し入れする際に把持されるとともに、受皿がグリル庫内に収納された状態にあってはグリル庫の前面開口の下半部に位置される把持部材と、
グリル庫内で前後方向にスライド可能に設けられ、該受け皿をグリル庫内に収納する過程において該受け皿の後ろ端部に当接されて、グリル庫の後方向に押し込まれる当接部と、当該当接部と上記グリル扉の支点よりも下位置とを連結し、当接部が前方向にスライドしたときには上記グリル扉を開く一方、当接部が後方向にスライドしたときにはグリル扉を閉じる連結腕部からなり、上記受皿の前後方向へ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、
該連結部材をグリル庫の前方向に向けて付勢する付勢手段とを備え、
上記受皿がグリル庫内に収納された際には上記グリル扉と上記把持部材とにより、グリル庫の前面開口を密閉する一方、
受皿がグリル庫内から前方向に引き出されたときには、上記付勢手段により連結部材が前方向にスライドして、前記グリル扉が上方向に片開き状に開くようにされたグリル扉の開閉装置を有するグリルにおいて、
上記付勢手段の付勢力に抗じて、上記連結部材の前方向へのスライド速度を遅らせる速度調節装置を設けたことを要旨とする。
【０００５】
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、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、
上記付勢手段による上記連結部材の前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を連動させたことを要旨とする。
【０００６】
また、本発明の請求項３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、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、
上記筒体と上記スピンドルとの摺動面に粘着用グリスを塗布し、
上記付勢手段による上記連結部材の前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を連動させたことを要旨とする。
【０００７】
また、本発明の請求項４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、直線運動を回転運動に替えるためのカム体とスライドバーとにより構成され、
上記カム体の回転摺動面に粘着用グリスを塗布し、
上記付勢手段による上記連結部材の前方向への付勢力に対して抵抗を与えるように、該スライドバー上を回転移動するカム体の動きを連動させたことを要旨とする。
【０００８】
上記構成を有する本発明の請求項１記載のグリルでは、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、速度調節装置が連結部材の前方向へのスライド速度を遅らせる結果、グリル扉の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。
【０００９】
また、本発明の請求項２記載のグリルでは、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。
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。
【００１０】
また、本発明の請求項３記載のグリルでは、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。
【００１１】
また、本発明の請求項４記載のグリルでは、カム体の回転摺動面に粘着用グリスが塗布されているために、スライドバー上を回転して移動するカム体の回転運動に対する抵抗が増す。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、カム体の動きを連動させておくと、この大きな抵抗のために、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。
【００１２】
【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３は、本実施形態のグリルの概略構成図であり、図１が受皿を奥まで押しこんだ状態の側面図、図２が受皿を手前に引き出した状態の側面図、図３が上面図である。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。
【００１３】
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２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。
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の先端部がはめ込まれる。そして、グリル庫５の奥行き部位の左右両側壁面５ｂ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、この長溝孔１６に連動腕１４の基端部が遊挿され、この各連動腕１４の基端部は受皿３の奥行壁外面に当接される連結バー１７の両端部に連結されている。さらにこの連動腕１４の基端部に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。
【００１４】
連動腕１４の水平方向に伸びた水平部位１４ａ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の軸がＬ字状の止板４１を介して取り付けられる。連動腕１４に止板４１の一辺を固定し、止板４１のもう一辺にピストン３１の軸を貫通させ、止板４１の両側からピストン３１をボルト４２ａ，４２ｂで止めつけることによりピストン３１の軸は連動腕１４に固定される。以下、速度調節装置３０について詳述する。
図４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から構成される。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がはめ込まれ、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の軸を貫通させてはめ込まれ、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。
【００１５】
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。
また、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。
【００１６】
このように構成されたグリル１によれば、取手９をにぎって受皿３をグリル庫５より引き出す時（図１→図２）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。しかしながら、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。すなわち、受皿３は、そのまま引き出されるものの、グリル扉８は、ゆっくり回動するため勢い良く開くことはない。このため、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。
【００１７】
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２→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。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。
【００１８】
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５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６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。
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７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。
また、図８及び図９に示すように、速度調節装置６０をカム体６２とスライドバー６１とで構成しても良い。図９は、図８中の一点鎖線Ａ−Ａで切られた断面を側面から見た図である。この速度調節装置６０は、詳しくは、スライドバー６１をグリル庫５の底壁５ａに固定し、このスライドバー６１と噛み合って回転するカム体６２の回転軸６３を連動腕１４の水平部位１４ａに開口した連通孔６５に挿通して取り付け、カム体６２の回転摺動面６４に粘着用グリスを塗布する構成である。スライドバー６１上を回転して移動するカム体６２の回転運動に対する抵抗がグリスの粘着性によって増し、連動腕１４の進退移動に対する抵抗も増すので、引っ張りバネ１８は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。
【００１９】
【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、速度調節装置が連結部材の前方向へのスライド速度を遅らせる結果、グリル扉の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。
【００２０】
更に、本発明の請求項２記載のグリルによれば、シリンダーとピストン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。また、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。
【００２１】
更に、本発明の請求項３または請求項４記載のグリルによれば、筒体とスピンドル、あるいはカム体とスライドバ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。

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 guide rail 6 on the bottom wall 5a and 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 fixed to the front opening side wall 7, and the distal end portion 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 is fitted in the shaft hole 13. It is.
A long groove hole 16 extending in the forward and backward movement direction of the tray 3 is formed in the left and right side wall surfaces 5b of the depth portion of the grill cabinet 5, and the base end portion of the interlocking arm 14 is loosely inserted into the long groove hole 16, and The base end portion of the arm 14 is connected to both end portions of the connecting bar 17 that is in contact with the outer surface of the depth wall of the tray 3. Further, the other end of the tension spring 18 having one end fixed to the base end portion of the interlocking arm 14 is engaged with a latching pin 19 protruding from the front portion of the grill cabinet side wall 5b, whereby the interlocking arm 14 and the connecting bar are connected. 17 is always pushed and urged in the forward direction (front side) 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 pivot point. 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 guide rail 6, 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.
[0003]
[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 once the receiving tray 3 is given a force that overcomes the locking force of the stopper 20 and quickly pulled out 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 gist is that the movement of the cam body rotating on the slide bar is interlocked so as to provide resistance against the forward biasing force of the connecting member by the biasing means.
[0008]
In the grill according to claim 1 of the present invention having the above-described configuration, when the tray is slid and put in and out of the grill cabinet, the connecting member opens and closes the grill door in conjunction with the slide of the tray. 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 tends to rotate vigorously because it is urged in the opening direction, but the speed adjusting device delays the sliding speed in the forward direction of the connecting member. Since the rotation speed of the door in the opening direction is delayed, the grill door opens 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.
[0009]
In the grill according to claim 2 of the present invention, when the piston is moved in the cylinder in the direction in which the umbrella-shaped elastic body at the tip opens, the umbrella-shaped elastic body opens and the elastic body and the inner surface of the cylinder are in close contact with each other. 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.
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.
[0010]
Further, in the grill according to claim 3 of the present invention, the adhesive grease is applied to the sliding surface between the cylindrical body and the spindle, and the resistance between the cylindrical body 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.
[0011]
In the grill according to claim 4 of the present invention, since the adhesive grease is applied to the rotational sliding surface of the cam body, the resistance to the rotational motion of the cam body rotating on the slide bar increases. . Therefore, if the movement of the cam body is interlocked so as to resist the urging force of the urging means that urges the grill door in the opening direction, the grill door slowly moves due to this large resistance. Only open. Therefore, it is possible to prevent an unpleasant collision sound due to the grill door hitting the appliance body.

DETAILED DESCRIPTION OF THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the grill of the present invention will be described below with reference to FIGS. 1 to 3 are schematic configuration diagrams of the grill according to the present embodiment, in which FIG. 1 is a side view of a state where the tray is pushed in to the back, FIG. 2 is a side view of a state where the tray is pulled forward, FIG. Is a top view. The grill 1 of the present embodiment is different from the above-described conventional grill 101 only in that a speed adjusting device 30 for delaying the rotation speed of the grill door 8 in the opening direction is provided, and thus overlapping is avoided. Therefore, the same reference numerals are given to the configurations of the same parts, and detailed description thereof is omitted.
[0013]
A substantially L-shaped connecting portion 11 is fixed to both sides inside the grill door 8 of the grill 1, and a support shaft 12 that serves as a pivot point of the connecting portion 11 is provided at one end of the connecting portion 11. The support shaft 12 is fixed to the front opening side wall 7, and the grill door 8 can be rotated by a certain angle in a single-opening manner in the vertical direction with the support shaft 12 as a fulcrum. As shown in FIG. 1, when the grill door 8 is fully closed (when the tray 3 is stored), the lower end of the grill door 8 is engaged with the protruding plate 21 provided on the handle 9 to The front opening 22 is securely closed so that there is no gap. As shown in FIG. 2, when the grill door 8 is fully opened (when the tray 3 is pulled out), the engagement is released and the grill door 8 can be opened without any problem. It can be done.
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. Part is inserted. And the long groove hole 16 extended in the advancing / retreating movement direction of the saucer 3 is established in the right-and-left both-side wall surface 5b of the depth part of the grill warehouse 5, The base end part of the interlocking arm 14 is loosely inserted in this long groove hole 16, The base end portion of the interlocking arm 14 is connected to both end portions of the connecting bar 17 that is in contact with the outer surface of the depth wall of the tray 3. Further, the other end of the tension spring 18 having one end fixed to the base end portion of the interlocking arm 14 is engaged with a latching pin 19 protruding from the front portion of the grill cabinet side wall 5b, whereby the interlocking arm 14 and the connecting bar are connected. 17 is always pushed and urged in the forward direction of the tray 3. Further, 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 forward by the urging force of the tension spring 18 and determines the storage position.
[0014]
In the horizontal portion 14 a extending in the horizontal direction of the interlocking arm 14, the axis of the piston 31 of the speed adjusting device 30 (described later) for delaying the rotational speed of the grill door 8 in the opening direction is interposed through an L-shaped stop plate 41. Attached. One side of the stop plate 41 is fixed to the interlocking arm 14, the shaft of the piston 31 is passed through the other side of the stop plate 41, and the piston 31 is fastened from both sides of the stop plate 41 with bolts 42a and 42b. Is fixed to the interlocking arm 14. Hereinafter, the speed adjusting device 30 will be described in detail.
As shown in FIG. 4, the speed adjusting 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 inserted into the base end of the cylinder 32 so that the shaft of the piston 31 passes through the shaft hole 39. An open chamber 38 is formed between the body 33 and the body 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.
[0015]
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. The resistance at this time is determined by the orifice diameter. 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.
Further, 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.
[0016]
According to the grill 1 configured as described above, when the tray 3 is pulled out from the grill cabinet 5 with the handle 9 (FIG. 1 → FIG. 2), the connection is urged toward the front side by the tension spring 18. The bar 17 moves forward in the long slot 16 together with the tray 3 by a predetermined stroke, and the interlocking arm 14 moves 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 pulled out. The grill door 8 can only rotate slowly because it cannot follow. That is, although the tray 3 is pulled out as it is, the grill door 8 does not open vigorously because it rotates slowly. For this reason, it can prevent that the grill door 8 and the instrument main body collide and an unpleasant collision sound is produced.
[0017]
On the other hand, when the tray 9 is put into the grill cabinet 5 by holding the handle 9 (FIG. 2 → 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 and can be performed smoothly as before without the need for extra power. 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.
[0018]
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. Moreover, as shown in FIG. 6, you may provide both the orifice 34 and the pore 43 simultaneously. Also in this case, when the piston 31 is moved to the left side, air can move only into the sealed chamber 35 because the air can move only through the orifice 34 and the pore 43, and the piston 31 is moved to the right side. 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.
Further, in this embodiment, the speed adjusting device 30 is constituted by the cylinder 32 and the piston 31, but as shown in FIG. 7, it is constituted by the cylinder 51 and the 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. Can be prevented.
Further, as shown in FIGS. 8 and 9, the speed adjusting device 60 may be composed of a cam body 62 and a slide bar 61. FIG. 9 is a view of a cross section taken along the alternate long and short dash line AA in FIG. Specifically, the speed adjusting device 60 fixes the slide bar 61 to the bottom wall 5 a of the grill 5 and rotates the rotating shaft 63 of the cam body 62 that meshes with the slide bar 61 to the horizontal portion 14 a of the interlocking arm 14. In this configuration, the adhesive grease is applied to the rotational sliding surface 64 of the cam body 62 by being inserted through the open communication hole 65 and attached. Since the resistance to the rotational motion of the cam body 62 that rotates and moves on the slide bar 61 is increased by the adhesiveness of the grease, and the resistance to the forward and backward movement of the interlocking arm 14 also increases, the tension spring 18 slowly elastically deforms. The grill door 8 can be prevented from vigorously rotating in the opening direction, and unpleasant collision noise can be prevented from being generated.
[0019]
【The invention's effect】
As described above in detail, according to the grill according to the first aspect of the present invention, the grill door is trying to open and vigorously rotated by the biasing force of the biasing means, the speed adjusting device connecting member As a result of delaying the sliding speed in the forward direction, the rotation speed of the grill door in the opening direction is delayed, so the grill door opens slowly. 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.
[0020]
Furthermore, according to the grill of the second aspect of the present invention, the speed adjusting device can be manufactured at a low cost with a simple configuration of the cylinder and the piston, so that the manufacturing cost can be suppressed. In addition, it does not require extra force for storing the saucer, and can be performed smoothly as before, which is convenient.
[0021]
Furthermore, according to the grill according to claim 3 or claim 4 of the present invention, the speed adjusting device can be manufactured at a low cost with a simple configuration of the cylindrical body and the spindle or the cam body and the slide bar. Can be suppressed.
