Description

本発明は、例えば複数のパネルを列設して構築した壁体の点検口のような開口を開閉する開き扉を施解錠するのに好適な開き扉の施解錠機構に関する。   The present invention relates to an opening / closing locking / unlocking mechanism suitable for locking / unlocking an opening / closing door that opens and closes an opening such as a wall inspection port constructed by arranging a plurality of panels, for example.

最近のビル建築物では、複数の金属製パネルを列設して出っ張りなく一面フラットに室内壁を構築するため、設備の点検口を開閉する開き扉の設置個所も、施解錠操作のドアハンドルのような突起物が表の外側に出っ張らない一見して壁のように見える外観であることが要請されている。そこで、従来の開き扉の施解錠機構の中には、ケースハンドルを用いて扉の表の外側からドアハンドルが大きく突出しないような構造にしたものや、配電盤の収納箱の扉のように扉を開ける使用時にドアハンドルを取り付け、その不使用時にはドアハンドルを取り外すようにした構造のものがある（特許文献１参照）。   In recent building constructions, multiple metal panels are arranged in a row to construct an indoor wall that is flat and flat. There is a demand for an appearance that looks like a wall at a glance where such protrusions do not protrude outward. Therefore, in some conventional door opening / unlocking mechanisms, doors such as those that use a case handle so that the door handle does not protrude significantly from the outside of the front of the door, or the door of a switchboard storage box door, etc. There is a structure in which a door handle is attached when the door is used and the door handle is removed when the door is not used (see Patent Document 1).

しかし、従来、ケースハンドルを用いた例では、扉面からケースハンドル自体の存在が目立ってしまうし、ドアハンドルが着脱式のものでは、扉を開ける際にドアハンドルを引き抜くと、それが抜け落ちてしまう等の問題があった。   However, in the conventional case using a case handle, the presence of the case handle is conspicuous from the door surface. If the door handle is detachable, if the door handle is pulled out when opening the door, it will fall off. There was a problem such as.

そこで、出願人は、閉状態において開き扉の外側に施解錠操作用ハンドルのような突出物のない美的外観を得られる一方、開き扉を外側から容易に施解錠できる開閉装置を提案している。この従来の開き扉の施解錠機構は、図１６に示すように、パネルｗ・ｗ´間の目地部１に外側へ臨む鍵操作用の***１ａを設け、目地部１の内側に装置本体２を設置し、装置本体２は、鍵穴３ａを鍵操作用***１ａに合わせて設けられるシリンダ錠３と、施解錠時は鍵操作用***１ａを通して鍵穴３ａに回転自在に抜き差しする鍵棒４と、鍵棒４を差し込んでシリンダ錠３の内部で正逆方向に回転すると、その回転に連動して開き扉５をロックするロック位置又はロック解除位置に回動するロックレバー６を備え、鍵棒４を、鍵操作用***１ａに通して鍵穴３ａに差し込み錠内部で正逆方向に回動すれば、開き扉５を外側から容易に施解錠できる構成になっている。   Therefore, the applicant has proposed an opening and closing device that can obtain an aesthetic appearance without protrusions such as a handle for locking and unlocking operation on the outside of the opening door in the closed state, and can easily lock and unlock the opening door from the outside. . As shown in FIG. 16, this conventional door locking / unlocking mechanism is provided with a small hole 1 a for key operation that faces the joint 1 between the panels w and w ′, and the device body 2 inside the joint 1. The device body 2 includes a cylinder lock 3 provided with a key hole 3a aligned with the key operation small hole 1a, and a key bar 4 that is rotatably inserted into and removed from the key hole 3a through the key operation small hole 1a when unlocked. When the key bar 4 is inserted and rotated in the forward / reverse direction inside the cylinder lock 3, a lock lever 6 that rotates to the locking position or the unlocking position for locking the opening door 5 in conjunction with the rotation is provided. Is inserted into the key operation small hole 1a, inserted into the key hole 3a, and rotated in the forward and reverse directions inside the lock, the opening door 5 can be easily locked and unlocked from the outside.

ところが、従来の開き扉の施解錠機構では、開き扉の開閉時に、その都度、鍵棒４の先端を、目地部１の狭い隙間から鍵操作用***１ａを通して鍵穴３ａに差し込んで開き扉５を外側から施解錠するが、隙間の幅が狭いと、鍵棒４の先端が誤って目地部１の両縁に衝突しやすく、そのために目地部１が傷だらけになり、折角、いったん壁面が一面フラットになって向上した点検口周りの美的外観が経時に悪化する一方、だからと言って、鍵棒の差込み操作が容易になるように目地部１の幅を拡げると、閉時、一見すると壁のように見えるはずの外側正面に縦に目地部１の凹みが目立って点検口周りの美的外観が低下するという課題があった。   However, in the conventional door unlocking / locking mechanism, each time the door is opened and closed, the end of the key bar 4 is inserted into the key hole 3a through the key operation small hole 1a from the narrow gap of the joint 1 to open the opening door 5. Locking and unlocking from the outside, but if the width of the gap is narrow, the tip of the key stick 4 is likely to accidentally collide with both edges of the joint 1, so that the joint 1 becomes full of scratches, and the wall is once folded. While the aesthetic appearance around the inspection port, which has been improved by flattening, deteriorates over time, it is said that if the width of the joint portion 1 is widened so that the operation of inserting the key bar becomes easy, the wall at first glance will appear when closed. There was a problem that the dent of the joint portion 1 was conspicuous vertically on the outer front surface that should look like the above, and the aesthetic appearance around the inspection port deteriorated.

しかも、従来の開き扉の施解錠機構では、作業のため設備の点検口を頻繁に出入りするたびに、都度、防犯のため鍵棒４を鍵穴３ａに差し込んで開き扉５を施錠操作する必要
があるが、出入りするたびに合鍵を使うために作業性が悪く、点検口という手狭で薄暗い中では、小さな鍵穴位置を手で探って探し出すことが面倒になるという作業性に課題があった。他方、作業者に予め合鍵を渡して管理を作業者に委ねていても、合鍵を紛失したり勝手に複製して悪用するという防犯性に課題があった。 Moreover, in the conventional door unlocking / unlocking mechanism, it is necessary to insert the key bar 4 into the keyhole 3a and lock the opening door 5 every time the equipment inspection port is frequently moved in and out for work. However, there is a problem in workability that it is troublesome to search and find a small keyhole position by hand in a narrow and dimly lit inspection port, because the key is used every time it enters and leaves. On the other hand, even if the key is handed over to the worker in advance and the management is entrusted to the worker, there is a problem with the crime prevention property that the key is lost or copied without permission.

そこで、請求項１に記載の発明は、たとえば以下に示す図示実施の形態のとおり、壁体Ｗに開設した開口を開閉する開き扉の戸先側木口１１ｃから外側に鍵穴２２を臨ませて開き扉に設置する錠前Ａと、該錠前Ａの合鍵１９を前記鍵穴２２に挿し込んでする施解錠操作に従い開き扉をロックする施錠位置とロックを解除する解錠位置の間を回動して開き扉を施解錠するロックレバーＲと、解錠時に外側から前記鍵穴２２を臨む開き角度だけ開扉する解錠操作位置に開き扉を案内する開扉ガイド手段Ｃと、を備える開き扉の施解錠機構であって、前記ロックレバーＲは、合鍵１９と一体に施錠又は解錠方向に回動可能に前記錠前Ａに基端部２０ｂを連結し、基端部２０ｂと先端部２０ａ間に回動規制部を設けるクランク２０と、該クランク２０に回動可能に枢着し、壁体Ｗ側の受具６５に係脱させて開き扉を施解錠するフック部２５ｂと廻り止め部２５ａを備えたリンク２５とで構成し、前記開扉ガイド手段Ｃは、開き扉を解錠操作位置に案内したとき、前記ロックレバーＲのフック部２５ｂが突き当たる高さ位置の壁体Ｗ側に前記受具６５を設置し、前記ロックレバーＲは、常時は、該受具６５に前記リンク２５のフック部２５ｂが係止する向きに回動付勢する一方、前記廻り止め部２５ａが前記クランクの回動規制部に突き当って前記フック部２５ｂが施錠姿勢位置に位置決め保持し、開き扉を閉めて前記リンク２５のフック部２５ｂが前記受具６５に突き当たると、該フック部２５ｂが前記受具６５に係止して開き扉をオートロックすることを特徴とする。   Therefore, the invention described in claim 1 opens with the keyhole 22 facing outward from the door-end side end 11c of the opening door that opens and closes the opening opened in the wall W, for example, as shown in the embodiment shown below. The lock A to be installed on the door and the lock key 19 of the lock A inserted in the keyhole 22 are rotated and opened between the locked position for locking the door and the unlocked position for releasing the lock. A lock lever R for locking and unlocking the door, and an opening guide means C for opening and guiding the door to an unlocking operation position for opening the door at an opening angle facing the keyhole 22 from the outside when unlocked. The lock lever R is a mechanism in which a base end portion 20b is connected to the lock A so as to be rotatable in the locking or unlocking direction integrally with the key 19, and is rotated between the base end portion 20b and the front end portion 20a. Crank 20 provided with a restricting portion, and crank 20 The door opening guide means includes a hook portion 25b that is pivotally attached and is engaged with and disengaged from the receiving member 65 on the wall body W side to lock and unlock the opening door, and a link 25 having a rotation stop portion 25a. C installs the receiver 65 on the wall W side at a height position where the hook portion 25b of the lock lever R abuts when the opening door is guided to the unlocking operation position. The hook 65 b of the link 25 is urged to rotate in a direction in which the hook 25 b of the link 25 is locked to the receiver 65, while the anti-rotation portion 25 a abuts against the rotation restricting portion of the crank and the hook portion 25 b is locked. When the hook 25b of the link 25 abuts against the receiving member 65 after being held in position and closed, the hook 25b is locked to the receiving member 65 to automatically lock the opening door. And

請求項２に記載の発明は、請求項１に記載の開き扉の施解錠機構において、たとえば以下に示す図示実施の形態のとおり、前記ロックレバーＲは、解錠時、前記リンク２５を解錠方向に回動して起立状態の解錠姿勢位置に保持し、該リンク２５に可撓性を有する戻り止め部材を装着し、該戻り止め部材が前記クランクの回動規制部に突き当った回動制状態で前記リンク２５をそのまま解錠姿勢位置に保持してなることを特徴とする。 The invention according to claim 2 is the unlocking / unlocking mechanism of the opening door according to claim 1, for example, as shown in the embodiment shown below, the lock lever R unlocks the link 25 when unlocked. The link 25 is mounted with a flexible detent member, and the detent member hits against the rotation restricting portion of the crank. The link 25 is held in the unlocked posture position as it is in a controlled state.

請求項３に記載の発明は、請求項１又は２に記載の開き扉の施解錠機構において、たとえば以下に示す図示実施の形態のとおり、前記開扉ガイド手段Ｃは、前記受具６５および該受具を横架する取付フレーム４５に設ける取付穴６９・ を、前記錠前Ａおよび前記ロックレバーＲに対して上下方向又は前後方向のいずれか一方向又は双方向に取付位置を調整する長穴で形成してなることを特徴とする。   The invention described in claim 3 is the opening / closing locking / unlocking mechanism according to claim 1 or 2, wherein, for example, as shown in the embodiment shown below, the opening guide means C includes the receiver 65 and the receiving device 65. A mounting hole 69 provided in the mounting frame 45 that horizontally mounts the receiving tool is an elongated hole that adjusts the mounting position in one direction or both directions of the lock A and the lock lever R in either the vertical direction or the front-rear direction. It is formed.

請求項１に記載の発明によれば、施錠時は、開き扉を閉めてロックレバーのリンクのフック部が受具に突き当たると、フック部が自動的に受具に係止して開き扉をオートロックすることで、合鍵が不要になることから、作業のため設備の点検口を頻繁に出入りするたびに、都度、防犯のため合鍵を使った面倒な施錠操作も必要でなくなり、点検口という手狭で薄暗い中で小さな鍵穴位置を手で探って探し出す面倒な作業もなくなって作業性も向上し、作業者に合鍵を渡すこともないので合鍵を紛失したり勝手に複製して悪用することをなくし防犯性も高くすることができる。   According to the first aspect of the present invention, at the time of locking, when the opening door is closed and the hook portion of the link of the lock lever hits the receiving device, the hook portion is automatically locked to the receiving device and the opening door is opened. The automatic lock eliminates the need for a key, so every time you go in and out of the facility's inspection port frequently for work, it is no longer necessary to perform a troublesome locking operation using the key for crime prevention. Searching for and searching for a small keyhole position in a narrow and dim place eliminates the troublesome work and improves workability, and does not pass the key to the worker, so it is necessary to lose the key or duplicate it for abuse The crime prevention property can be increased.

また、請求項１に記載の発明によれば、開き扉の開閉に応じて施錠又は解錠操作するとき、外側から合鍵を鍵穴に差し込んで操作できる開き角度だけ僅かに開扉した施解錠操作位置まで開いて、合鍵を使って施解錠操作すればよく、従来のようにパネル間の目地部を利用して鍵棒の先端を目地部の狭い隙間に通して施解錠する操作が必要にならない構成にするため、鍵棒の先端が誤って目地部の狭い隙間の両縁に衝突して目地部が傷だらけになるようなこともなく、点検口など開口周りの美的外観が悪化するのを防止することができる。しかも、パネル間の目地部を全く利用しないから、目地部の隙間を限りなくゼロに近く狭くした壁体の構築が実現し、そして、開き扉が閉状態においては、開き扉が点検口等の開口に収まって壁体と面一になり、外側から鍵穴なども露見しないから、全体に美感を更に高めることもできる。   According to the invention described in claim 1, when performing the locking or unlocking operation according to the opening / closing of the opening door, the unlocking / unlocking operation position is opened slightly by the opening angle at which the key can be inserted from the outside into the keyhole and operated. It can be opened and unlocked using a joint key, and there is no need to use the joint between the panels to lock and unlock the tip of the key rod through the narrow gap in the joint as in the past. Therefore, the tip of the key bar accidentally collides with both edges of the narrow gap in the joint, and the joint is not damaged, preventing the deterioration of the aesthetic appearance around the opening such as the inspection port. can do. Moreover, since the joints between the panels are not used at all, it is possible to construct a wall body in which the gaps between the joints are as close to zero as possible, and when the opening door is closed, the opening door can be used as an inspection port. Since it fits in the opening and is flush with the wall body and does not expose the keyhole from the outside, the overall aesthetics can be further enhanced.

請求項２に記載の発明によれば、施錠時にオートロック機能をオフにするときは、ロックレバーＲは、リンクを解錠方向に回動して起立状態の解錠姿勢位置に保持し、リンクに可撓性を有する戻り止め部材を装着し、その戻り止め部材がクランクの回動規制部に突き当った回動制状態でリンクをそのまま解錠姿勢位置に保持される。必要な解錠時間を経てして後、開き扉を再び施錠する場合は、付勢部材の押し付け付勢力に抗してリンクを倒して、クランクの先端部と重なる伏せた元のオートロック姿勢の施錠位置に戻せばよい。そのとき、戻り止め部材は可撓性を有するから、撓みながら変形して容易に施錠位置に戻すこともできる。 According to the second aspect of the present invention, when the auto-lock function is turned off at the time of locking, the lock lever R rotates the link in the unlocking direction and holds the link in the standing unlocked posture position. A detent member having flexibility is mounted on the link, and the link is held in the unlocked posture position as it is in a pivoting state in which the detent member abuts against the rotation regulating portion of the crank. When the door is to be locked again after the necessary unlocking time, the link is tilted against the urging force of the urging member, and the original auto-locking posture of the original position that overlaps the tip of the crank is applied. Return to the locked position. At that time, since the detent member has flexibility, it can be easily returned to the locked position by being deformed while being bent.

請求項３に記載の発明によれば、開扉ガイド手段は、受具と取付フレームに設ける取付穴を長穴で形成するから、たとえ手狭で薄暗い点検口などのにあっても、錠前およびロックレバーに対して取付位置を上下方向および前後方向に手間なく簡単に調整することができる。   According to the third aspect of the present invention, since the door opening guide means is formed with a long mounting hole provided in the support and the mounting frame, even if it is a narrow and dimly lit inspection port, the lock and lock The mounting position with respect to the lever can be easily adjusted in the up and down direction and the front and rear direction without any trouble.

以下、図面を参照しつつ、本発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１および図２に示すように、本発明の一例である開き扉の施解錠機構を適用した壁体Ｗは、パネルｗ１・ｗ２・ｗ３…を列設して面一に構築した室内壁で、両側の袖パネルｗ１・ｗ３に対して中間のパネルｗ２を、たとえば室内設備にある壁体Ｗに開設した奥行きの狭い点検口Ｓを開閉する開き扉Ｄで形成する。図示例のパネルｗ１・ｗ２・ｗ３…は、それぞれスチール板の両端をクランク状に折り返して竪框を形成し、隣り合う竪框相互の継目に外側から内側が臨めない立て目地が形成されている。   As shown in FIG. 1 and FIG. 2, a wall body W to which an unlocking mechanism for an open door as an example of the present invention is applied is an indoor wall constructed by arranging panels w1, w2, w3. An intermediate panel w2 with respect to the sleeve panels w1 and w3 on both sides is formed, for example, by an opening door D that opens and closes a narrow-depth inspection port S opened in a wall body W in an indoor facility. The panels w1, w2, w3, etc. in the illustrated example each form a ridge by folding both ends of a steel plate into a crank shape, and standing joints that do not face the inside from the outside to the joint between adjacent ridges are formed. .

壁体Ｗの袖パネルｗ１は、開き扉Ｄ側の端部において、図３に示すように、スチール板を断面Ｌ状に屈曲して凹状の戸当り１０ａを形成すると共に、戸当り部１０ａからそれと逆向きの断面Ｌ状に屈曲して凸状の取付部１０ｂを形成し、凹状の戸当り部１０ａと凸状の取付部１０ｂとで竪框１０を構成する。それら戸当り部１０ａと取付部１０ｂの間には、一部折り重ね部分１０ｃを設けて凹溝１２を形成し、凹溝１２にクッション材１３を嵌め込んで戸当り時の衝撃を緩衝する戸当り部１０ａを形成する。   As shown in FIG. 3, the sleeve panel w <b> 1 of the wall W forms a concave door stopper 10 a by bending a steel plate into a cross-sectional L shape as shown in FIG. 3, and from the door stopper 10 a. A convex attachment portion 10b is formed by bending in a cross-section L shape opposite to the above, and the flange 10 is constituted by the concave door stop portion 10a and the convex attachment portion 10b. Between the door contact portion 10a and the mounting portion 10b, a partially folded portion 10c is provided to form a concave groove 12, and a cushion material 13 is fitted into the concave groove 12 to cushion the impact at the time of the door contact. The contact portion 10a is formed.

一方、開き扉Ｄは、扉厚が一定規格の、例えば４０ｍ~４５ｍｍで、戸先側端部を断面Ｚ状に屈曲して戸先側竪框１１を形成する。開き扉Ｄの戸先側竪框１１は、図４に示すように、閉時に袖パネルｗ１の戸当り部１０ａと対向する内側の戸当り部１１ａと、戸当り部１１ａと平行な目地隠し部１１ｂと、目地隠し部１１ｂと戸当り部１１ａとの間の戸先側木口１１ｃとで形成する。木口１１ｃは、その表面が開き扉Ｄの外側に向けて傾斜する。開き扉Ｄの戸先側木口１１ｃが合鍵１９を使って施解錠操作する開き扉Ｄの外側に向けて傾斜していると、外側から合鍵１９を鍵穴２２に差し込んで操作できる開き角度だけ開扉した半開き状態であっても、合鍵１９を鍵穴２２に対して簡単に抜き差し回動操作して開き扉Ｄを施解錠することができる。開き扉Ｄは、閉状態において、点検口Ｓに収まって壁体Ｗと面一になるように、吊元側の竪框１４を袖パネルｗ３に蝶番１６により回動自在に取り付ける。   On the other hand, the opening door D has a door thickness of a certain standard, for example, 40 m to 45 mm, and the door end side end portion is bent into a Z-shaped cross section to form the door end side rod 11. As shown in FIG. 4, the door end side arm 11 of the opening door D includes an inner door stopper portion 11 a that faces the door stopper portion 10 a of the sleeve panel w <b> 1 when closed, and a blindfold portion parallel to the door stopper portion 11 a. 11b and the door end side lip 11c between the joint concealment part 11b and the door stop part 11a. The front end of the wooden mouth 11c is inclined toward the outside of the door D. When the door end side end 11c of the opening door D is inclined toward the outside of the opening door D that is locked and unlocked by using the key 19, the door is opened by an opening angle that allows the key 19 to be inserted into the key hole 22 from the outside and operated. Even in the half-opened state, the key 19 can be easily inserted / removed with respect to the keyhole 22 and the opening door D can be locked / unlocked. In the closed state, the hinged door D is pivotally attached to the sleeve panel w3 by a hinge 16 so that the hinged door D is placed in the inspection port S and is flush with the wall W.

そこで、本発明の開き扉の施解錠機構では、図４および図５に示すように、この開き扉Ｄの戸先側木口１１ｃにシリンダ錠１５の直径に合わせて取付穴１７を穿設し、取付穴１７を開けた位置で戸先側木口１１ｃの内側に錠前Ａを組み付け、錠前Ａに、錠前Ａの合鍵１９を鍵穴２２に挿し込んでする施解錠操作に従い開き扉Ｄをロックする施錠位置とロックを解除する解錠位置の間を回動して開き扉Ｄを施解錠するロックレバーＲを連結する一方、袖パネルｗ１の扉側竪框１１の取付部１０ｂに開扉ガイド手段Ｃを取り付ける構成になっている。   Therefore, in the opening door locking / unlocking mechanism of the present invention, as shown in FIGS. 4 and 5, a mounting hole 17 is formed in the door end side end 11c of the opening door D in accordance with the diameter of the cylinder lock 15, Locking position in which the lock A is assembled to the inside of the door end side end 11c at the position where the mounting hole 17 is opened, and the door D is locked according to the locking / unlocking operation in which the lock key A is inserted into the key hole 22 in the lock A.

Positioning / holding means 30 is provided for controlling rotation while reciprocating between a locking position for locking the lock and an unlocking position for releasing the lock.

クランク２０は、基端部２０ｂにシリンダ錠１５の連結凸部１８ａと同じ矩形な回転規制穴３９およびその周縁にシリンダ１８と連れ回る回動範囲を規定するガイド穴４１を設ける一方、先端部２０ａに枢軸２６の軸穴２９を設け、合鍵１９と一体に施錠又は解錠方向に回動可能に錠前Ａに基端部２０ａを連結する。クランク２０は、先端部２０ａと基端部２０ｂの段差間を平板で結んで段状の回動規制部２０ｃを設ける。回動規制部２０ｃには、ばね掛け穴２７を有する。   The crank 20 is provided with a rectangular rotation restricting hole 39 that is the same as the connecting convex portion 18a of the cylinder lock 15 at the base end portion 20b and a guide hole 41 that defines a rotation range that rotates with the cylinder 18 at the periphery thereof, while the distal end portion 20a. A shaft hole 29 of the pivot 26 is provided on the base end 20a, and the base end portion 20a is connected to the lock A so as to be rotatable in the locking or unlocking direction integrally with the key 19. The crank 20 is provided with a stepped rotation restricting portion 20c by connecting a step between the tip end portion 20a and the base end portion 20b with a flat plate. The rotation restricting portion 20c has a spring hooking hole 27.

リンク２５は、肉厚で長めの金属板材を加工し、クランク２０の先端部２０ａに枢軸２６を支点に回動可能に枢着する軸穴２８を有する板カム状の廻り止め部２５ａと、鎌状、即ち三日月形状のフック部２５ｂとで形成し、廻り止め部２５ａとフック部２５ｂ間に首部を残し幅方向に切り欠いて係止口４０を凹設する。リンク２５は、係止口４０を開けた一側縁ｘと平行な他側縁ｙを含む周縁を板厚だけ平面で形成し、廻り止め部２５ａの周縁に円弧カム面ｗおよび直線平面状の廻り止め面ｚを周方向に連設する。   The link 25 is formed by processing a thick and long metal plate, and a plate cam-like detent 25a having a shaft hole 28 pivotally mounted on the tip 20a of the crank 20 with the pivot 26 as a fulcrum. And a crescent-shaped hook portion 25b, and a neck is left between the rotation stop portion 25a and the hook portion 25b so as to be cut out in the width direction, thereby forming the locking port 40 in a recessed manner. The link 25 has a flat surface that includes the other side edge y parallel to the one side edge x where the locking port 40 is opened, and has a circular cam surface w and a linear flat surface on the periphery of the rotation stop portion 25a. The rotation stop surface z is continuously provided in the circumferential direction.

位置決め保持手段３０は、図６および図７に示すように、戻り止め部材３６の掛け止めリブ３６ｃをリンク２５の一側縁ｘに掛け止め、枢軸２６を付勢部材３５のコイル部３５ａの中空内に通して回転中心穴２７・２８・２９を嵌挿し、枢軸２６を中心にリンク２５をクランク２０の先端部２０ａに回動可能に枢着する。 As shown in FIGS. 6 and 7, the positioning and holding means 30 latches the latching rib 36 c of the detent member 36 on one side edge x of the link 25, and the pivot 26 is hollow in the coil portion 35 a of the biasing member 35. The rotation center holes 27, 28, and 29 are inserted through the inside, and the link 25 is pivotally attached to the distal end portion 20 a of the crank 20 around the pivot 26.

そこで、ロックレバーＲにおいて、位置決め保持手段３０は、付勢部材３５のばね一端３５ｂを回動規制部２０ｃのばね掛け穴２９に係入し、Ｌ状のばね他端３５ｂを鎌状フック部２５ｂの他側縁ｙに掛け止めて、クランク２０に対してリンク２５を、枢軸２６を中心にフック部２５ｂの係止口４０が受具６５の掛け止め軸７５に係止する図中反時計方向に回動付勢する一方で、廻り止め面ｚがクランク２０の回転規制部２０ｃ上の平面に突き当たりフック部２５ｂの係止口４０が受具６５の掛け止め軸７５に係止する施錠姿勢位置に位置決め保持する。ロックレバーＲは、クランク２０の先端部２０ａのリンク２５を、図８（ａ）および図９（ａ）に示すように、クランク２０の先端部２０ａと重なる伏せたオートロック姿勢で施錠位置に保持する。 Therefore, in the lock lever R, the positioning holding means 30 engages the spring one end 35b of the urging member 35 into the spring hooking hole 29 of the rotation restricting portion 20c, and the L-shaped spring other end 35b to the sickle-like hook portion 25b. Hooked to the other side edge y, the link 25 with respect to the crank 20, and the locking port 40 of the hook portion 25 b centered on the pivot 26 to lock to the locking shaft 75 of the receiver 65 in the counterclockwise direction in the figure. While the rotation stop surface z abuts against the plane on the rotation restricting portion 20c of the crank 20 and the locking port 40 of the hook portion 25b is locked to the latch shaft 75 of the holder 65. Hold the positioning. The lock lever R holds the link 25 of the distal end portion 20a of the crank 20 in the locked position in a tilted auto-lock posture that overlaps the distal end portion 20a of the crank 20 as shown in FIGS. 8 (a) and 9 (a). To do.

一方、ロックレバーＲにおいて、開き扉Ｄを、一時、解錠して点検口Ｓを出入りする場合は、リンク２５を、付勢部材３５の付勢力に抗して、図８（ｂ）および図９（ｂ）に示すように、係止口４０と掛け止め軸７５の係合が外れる解錠方向に回動し、クランク２０に対して起立した解錠姿勢位置に保持する。 On the other hand, in the lock lever R, when the opening door D is temporarily unlocked and the inspection port S is moved in and out, the link 25 is resisted against the urging force of the urging member 35 as shown in FIG. As shown in FIG. 9B, the locking port 40 and the latching shaft 75 are rotated in the unlocking direction so as to be disengaged, and are held in the unlocking posture position standing with respect to the crank 20.

ロックレバーＲは、このように施錠時にオートロック機能をオフにするとき、リンク２５を解錠方向に回動して起立状態の解錠姿勢位置に保持し、リンク２５に装着した可撓性を有する戻り止め部材３６がクランク２０の回動規制部２０ｃに突き当った回動規制状態でリンク２５をそのまま起立した状態の解錠姿勢位置に保持される。点検作業に必要な解錠時間を経てして後、開き扉Ｄを再び施錠する場合は、付勢部材３５の押し付け付勢力に抗してリンク２５を倒して、クランク２おの先端部２０ａと重なる伏せた施錠姿勢位置に戻せばよい。そのとき、戻り止め部材３６は可撓性を有するから、撓みながら変形して容易に施錠位置に戻すこともできる。 When the lock lever R thus turns off the auto-lock function during locking, the link 25 is rotated in the unlocking direction and held in the unlocked posture position in the standing state. The detent member 36 having the detent member 36 is held in the unlocked posture position in the state where the link 25 is erected as it is in the rotation restricted state where the detent member 36 abuts against the rotation restricting portion 20 c of the crank 20. When the door D is locked again after an unlocking time necessary for the inspection work, the link 25 is tilted against the pressing biasing force of the biasing member 35, and the tip 20a of the crank 2 What is necessary is just to return to the position where the lock-down position was piled up. At that time, since the detent member 36 has flexibility, it can be easily deformed while being bent and easily returned to the locked position.

開扉ガイド手段Ｃは、図１０、図１１および図１２に示すように、長手なコ形枠状の取付フレーム４５内にプッシュラッチ５０を固設し、固定側のプッシュラッチ５０に対してスライダ５５を係合し、可動側のスライダ５５に受具６５を搭載してスライダ５５と一体に移動可能に構成する。   As shown in FIGS. 10, 11, and 12, the door opening guide means C is configured such that a push latch 50 is fixed in a long frame-shaped mounting frame 45, and a slider is fixed to the push latch 50 on the fixed side. 55 is engaged, and a receiving device 65 is mounted on the movable slider 55 so that the slider 55 can move together.

スライダ５５は、上下に向き合うガイドプレート５５ａ・５５ｂの片側を取付基板５５ｃで連結する一方、取付基板５５ｃと向き合う他側は支柱５５ｄで連結して取付口８を開口し、全体に箱形に形成する。取付基板５５ｃには、片側側縁の上下角縁に切欠き凹部６１・６１を設け、外側面にストッパ軸４４を握持するＵ形のホルダ６３を突設し、内側面の片側側縁の上下角縁に嵌込凸部６４ａ・６４ａを突設する。スライダ５５は、嵌込凸部６４ａ・６４ａを取付凹部６１・６１に嵌め込み、取付基板５５ｃの外側に取付ブロック６４を取り付け、内側に軸部先端に球形状の嵌合突起６２を突設した取付プレート５７を取り付ける。 The slider 55 is connected to one side of the guide plates 55a and 55b facing up and down by a mounting substrate 55c, and the other side facing the mounting substrate 55c is connected by a column 55d to open the mounting port 8 and is formed in a box shape as a whole. To do. The mounting substrate 55c is provided with notched recesses 61 and 61 at the upper and lower corners of the one side edge, and a U-shaped holder 63 for gripping the stopper shaft 44 on the outer side is projected, and the inner side of the one side edge Insertion convex parts 64a and 64a are projected from the upper and lower corner edges. The slider 55 is mounted by fitting the fitting convex portions 64a and 64a into the fitting concave portions 61 and 61, attaching the attachment block 64 to the outside of the attachment substrate 55c, and projecting the spherical fitting protrusion 62 at the tip of the shaft portion on the inside. A plate 57 is attached.

受具６５は、全体をく字状に屈曲した長手のケース状に形成し、下部側の直立部６５ａにホルダ６３の通し穴６６を設け、上部側の傾斜部６５ｂに細長矩形に開いた受け口７０を設け、受け口７０の開いた対向側板部６５ｃ・６５ｃ間に掛け止め軸７５を横架する。受具６５は、受け口７０を上向きにしてホルダ６３を通し穴６６に通して取付ブロック６４に直立部６５ａを嵌め込み、直立部６５ａにあけた取付穴７９に止めねじ５６を通してねじ込み、直立部６５ａを取付ブロック６４に固着してスライダ５５に搭載する。 The receiving device 65 is formed in a longitudinal case shape that is bent into a square shape as a whole, and is provided with a through-hole 66 of the holder 63 in the lower upright portion 65a, and in an elongated rectangular shape in the inclined portion 65b on the upper side. 70, and a latching shaft 75 is horizontally mounted between the opposed side plate portions 65c and 65c in which the receiving port 70 is opened. The receiving tool 65 has the receiving port 70 facing upward, the holder 63 is passed through the through hole 66, the upright portion 65a is fitted into the mounting block 64, and the set hole 56 is screwed into the mounting hole 79 formed in the upright portion 65a. It is fixed to the mounting block 64 and mounted on the slider 55.

開扉ガイド手段Ｃは、取付フレーム４５内の奥側において、プッシュラッチ５０を、前側の摺動ガイド部８０をストッパ軸４４に向けてガイド板４５ｂに固定する。一方、スライダ５５は、ガイドプレート５５ａ・５５ｂ間に取付フレーム４５のガイド板４５ｂに係合し、ガイドプレート５５ａ・５５ｂ間にプッシュラッチ５０を挟んでストッパ軸４４の方向に直線往復摺動可能に保持する。 The door opening guide means C fixes the push latch 50 on the back side in the mounting frame 45 to the guide plate 45 b with the front sliding guide portion 80 facing the stopper shaft 44. On the other hand, the slider 55 engages with the guide plate 45b of the mounting frame 45 between the guide plates 55a and 55b, and can linearly reciprocate in the direction of the stopper shaft 44 with the push latch 50 sandwiched between the guide plates 55a and 55b. Hold.

プッシュラッチ５０は、閉扉時には、スライダ５５、即ち、スライダ５５に搭載の受具６５を、内部付勢手段によりストッパ軸４４に向けて付勢する一方、ラッチピンの先端が係止部に係止し、図１３（ａ）に示すように第１ラッチ位置にロックした初期状態とする。そこで、プッシュラッチ５０は、閉扉状態において、図１３（ｂ）に示すように、スライダ５５を内部付勢手段に抗して押し込むと、ラッチピンの先端が移動し、図１３（ｃ）に示すように、スライダ５５を第１ラッチ位置から一定のストロークＬだけ引っ込んだ第２ラッチ位置に停止してロックする。次いで、いま第２ラッチ位置にあるスライダ５５を再び押し込むと、スライダ５５を、図１３（ｄ）に示すように、内部付勢手段の復帰力により前進し、第２ラッチ位置から一定のストロークＬだけ突出し、ホルダ６３でストッパ軸４４に係合した第１ラッチ位置に停止してロックする構造になっている。 When the push latch 50 is closed, the slider 55, that is, the receiving member 65 mounted on the slider 55 is urged toward the stopper shaft 44 by the internal urging means, while the tip of the latch pin is locked to the locking portion. As shown in FIG. 13A, the initial state is locked to the first latch position. Therefore, when the push latch 50 is closed, as shown in FIG. 13 (b), when the slider 55 is pushed against the internal biasing means, the tip of the latch pin moves, as shown in FIG. 13 (c). In addition, the slider 55 is stopped and locked at the second latch position retracted by a certain stroke L from the first latch position. Next, when the slider 55 which is now in the second latch position is pushed in again, the slider 55 is moved forward by the restoring force of the internal urging means as shown in FIG. It protrudes only, and is configured to stop and lock at the first latch position engaged with the stopper shaft 44 by the holder 63.

そこで、開扉ガイド手段Ｃにおいて、プッシュラッチ５０は、図３（ｄ）に示すように、都度、押すだけの操作でスライダ５５に搭載の受具６５を第１ラッチ位置と第２ラッチ位置との間を案内して直線往復摺動するストロークＬを、外側から鍵穴２２を臨む開き角度に合わせて設定する。   Therefore, in the door opening guide means C, as shown in FIG. 3 (d), the push latch 50 moves the receiving device 65 mounted on the slider 55 to the first latch position and the second latch position by simply pressing each time. A stroke L for linearly reciprocatingly sliding between them is set in accordance with an opening angle facing the keyhole 22 from the outside.

また、開扉ガイド手段Ｃは、図１および図２に示すように、スライダ５５に搭載の受具６５の受け口７０を、開き扉Ｄの戸先側木口１１ｃの内側に組み付けた錠前Ａに向けて、高さ方向は、リンク２５がクランク２０先端の取付部２０ａと重なる伏せた状態のロックレバーＲの高さ位置に合わせ、奥行方向には、受具６５が第１ラッチ位置にあるとき、開き扉Ｄの施錠位置に回動したロックレバーＲが受具６５の掛け止め軸７５に係止する位置で、袖パネルｗ１の扉側竪框１０の取付部１０ｂに取り付ける。   Further, as shown in FIGS. 1 and 2, the door opening guide means C is directed toward the lock A assembled with the receiving port 70 of the receiving device 65 mounted on the slider 55 inside the door end side end 11c of the opening door D. The height direction is adjusted to the height position of the lock lever R in a state where the link 25 overlaps with the mounting portion 20a at the tip of the crank 20, and in the depth direction, when the receiving tool 65 is in the first latch position, The lock lever R rotated to the locking position of the opening door D is attached to the attachment portion 10b of the door side collar 10 of the sleeve panel w1 at a position where the lock lever R is engaged with the latch shaft 75 of the support 65.

開扉ガイド手段Ｃは、図１２に示すように、取付フレーム４５に設ける取付穴６９、受具６５に設ける取付穴７７を、錠前ＡおよびロックレバーＲに対して取付位置を上下方向又は前後方向に調整する長穴で形成する。従って、図示例では、たとえ手狭で薄暗い点検口Ｓなどにあっても、錠前ＡおよびロックレバーＲに対して取付位置を上下方向および前後方向に手間なく簡単に調整することができる。 As shown in FIG. 12, the door opening guide means C has an attachment hole 69 provided in the attachment frame 45 and an attachment hole 77 provided in the receiver 65. It is formed with a long hole to be adjusted. Therefore, in the illustrated example, the mounting position can be easily adjusted in the vertical direction and the front-rear direction with respect to the lock A and the lock lever R even if the inspection port S is narrow and dim.

そこで、本発明では、この閉扉時、図１（ａ）、図２（ａ）、図３（ａ）、図４および図５（ａ）に示すように、ロックレバーＲのリンク２５が掛け止め軸７５に係止する第２ラッチ位置に止めて受具６５をロックする。   Therefore, in the present invention, when the door is closed, the link 25 of the lock lever R is latched as shown in FIGS. 1 (a), 2 (a), 3 (a), 4 and 5 (a). The holder 65 is locked by stopping at the second latch position to be engaged with the shaft 75.

従って、本発明では、この閉扉時、図１４（ａ）に示すように、開き扉Ｄを閉めて押し込んだとき、ロックレバーＲのリンク２５のフック部２５ｂが受具６５に当接すると、図１４（ｂ）に示すように、リンク２５が枢軸２６を支点に上向きに回動しながらフック部２５ｂが、図１４（ｃ）に示すように、自動的に受具６５に掛け止まり開き扉Ｄをオートロックし、合鍵を不要にすることから、作業のため設備の点検口Ｓを頻繁に出入りするたびに、都度、防犯のため合鍵を使った面倒な施錠操作も必要でなくなり、点検口Ｓという手狭で薄暗い中で小さな鍵穴位置を手で探って探し出す面倒な作業もなくなって作業性も向上し、しかも、作業者に合鍵を渡すことがなくなるので、合鍵を紛失したり勝手に複製して悪用されることもなくし防犯性も高くすることができる。   Therefore, in the present invention, when the door is closed, as shown in FIG. 14A, when the opening door D is closed and pushed in, the hook portion 25b of the link 25 of the lock lever R comes into contact with the receiving member 65. As shown in FIG. 14 (b), the link 25 rotates upward with the pivot 26 as a fulcrum, and the hook portion 25b automatically hooks and stops on the support 65 as shown in FIG. Because the lock is automatically locked and the key is not required, the troublesome locking operation using the key for security is not required every time the inspection port S of the equipment is frequently moved in and out for work. In this narrow and dim situation, the troublesome work of searching for and searching for a small keyhole position by hand is eliminated, and the workability is improved.In addition, the key is not given to the operator, so the key can be lost or duplicated without permission. Preventing abuse It can be higher sex.

その後、設備を点検するために点検口Ｓを開けるときは、開き扉Ｄの戸先側端部を押し込み、図５（ｂ）に示すように、第２ラッチ位置から一定のストロークＬだけ突出した第１ラッチ位置で停止し、この位置にロックする。すると同時に、開き扉Ｄは、内部付勢ばね５０のばね付勢力に基づいて、スライダ５５に押されて、図１（ｂ）および図７に示すように自動的に開方向へ回動する。   After that, when opening the inspection port S to check the equipment, the door end of the opening door D is pushed in, and as shown in FIG. 5 (b), it protrudes by a certain stroke L from the second latch position. Stop at the first latch position and lock to this position. At the same time, the opening door D is pushed by the slider 55 based on the spring biasing force of the internal biasing spring 50, and automatically rotates in the opening direction as shown in FIGS.

そのとき、本発明は、開き扉Ｄを開方向にばね付勢して押し開くプッシュラッチ５０が、ガイド手段で案内してスライダ５５が第１ラッチ位置と第２ラッチ位置との間を直線往復摺動するストロークＬを、開き扉Ｄの扉厚に合わせて設定しているから、図１（ｂ）、図７および図８に示すように、開き扉Ｄは、付勢ばねのばね付勢力に基づいて、スライダ５５に押されて自動的に開方向に回動するが、扉厚に相当する開き角度まで回動した施解錠操作位置に停止し、その施解錠操作位置にロックレバーＲのリンク２５のフック部２５ｂがスライダ５５の掛け止め軸７５に係止する施錠状態でロックすることができる。   At that time, in the present invention, the push latch 50 that pushes and pushes the opening door D in the opening direction is guided by the guide means, and the slider 55 linearly reciprocates between the first latch position and the second latch position. Since the sliding stroke L is set in accordance with the door thickness of the opening door D, as shown in FIGS. 1B, 7 and 8, the opening door D is a spring biasing force of the biasing spring. Is automatically rotated in the opening direction by being pushed by the slider 55, but stops at the locking / unlocking operation position rotated to the opening angle corresponding to the door thickness, and the lock lever R is moved to the locking / unlocking operation position. The link 25 can be locked in a locked state in which the hook portion 25 b of the link 25 is engaged with the latch shaft 75 of the slider 55.

そこで、そのまま点検口Ｓの外側から、シリンダ錠１５の鍵穴２２に合鍵１９を差し込んでシリンダ（外筒）１８内で解錠方向へプラグ（内筒）と一体にロックレバーＲを９０度回動し、スライダ５５のホルダ６３から外して解錠し、これによって開き扉Ｄのロックを解除する。それから、戸先側竪框１１に手を掛けて、図８および図９に示すように開き扉Ｄを更に開くように操作すればよい。   Therefore, from the outside of the inspection port S, the key 19 is inserted into the key hole 22 of the cylinder lock 15 and the lock lever R is rotated 90 degrees integrally with the plug (inner cylinder) in the unlocking direction in the cylinder (outer cylinder) 18. Then, the slider 55 is removed from the holder 63 and unlocked, thereby unlocking the opening door D. Then, it is sufficient to operate the door to the door side 11 and further open the opening door D as shown in FIGS. 8 and 9.

しかる後、点検口Ｓの外側から設備の点検作業を終え、そのまま点検口Ｓの外側から開き扉Ｄを閉じて施錠する場合は、図１（ｄ）、図３（ｄ）、図４（ｄ）、図５（ｄ）に示すように、いったん開き扉Ｄを、外側から鍵穴２２を臨む開き角度だけ開扉した施解錠操作位置まで押し戻してから、施解錠操作位置において、シリンダ錠１５の鍵穴２２に合鍵１９を差し込んで、今度は施錠方向へプラグ（内筒）と一体にロックレバーＲを９０度逆回動し、受具６５の掛け止め軸７５とリンク２５の係止口４０とを係止してロックレバーＲを受具６５に掛け止める。   Thereafter, when the inspection work of the equipment is finished from the outside of the inspection port S and the door D is closed and locked from the outside of the inspection port S as it is, FIG. 1 (d), FIG. 3 (d), FIG. 5), as shown in FIG. 5 (d), once the opening door D is pushed back from the outside to the locking / unlocking operation position opened by the opening angle facing the keyhole 22, the keyhole of the cylinder lock 15 is unlocked at the locking / unlocking operation position. 22, the key 19 is inserted, and this time, the lock lever R is rotated 90 degrees together with the plug (inner cylinder) in the locking direction, so that the latch shaft 75 of the holder 65 and the locking port 40 of the link 25 are connected. The lock lever R is hooked on the receiving member 65 by locking.

以上の図示実施の形態では、壁体Ｗの外側には、施解錠操作用にハンドルや取手等の突起物が全く設けられない構成なので、点検口Ｓの閉止状態において、一見すると開き扉も壁の一部のように見える面一な美観を得ることができる。しかも、パネルｗ１・ｗ２・ｗ３間の目地部を全く利用しないから、目地部の隙間を限りなくゼロに近く狭くした壁体の構築が実現し、全体に美感を更に一層高めることできる。   In the illustrated embodiment described above, the projections such as the handle and the handle are not provided at all on the outside of the wall body W for the locking / unlocking operation. You can get a beautiful aesthetic that looks like a part of. In addition, since the joint portion between the panels w1, w2, and w3 is not used at all, it is possible to construct a wall body in which the gap between the joint portions is made as narrow as possible, and the aesthetics can be further enhanced.

一方で、図示実施の形態では、開き扉Ｄが解錠時に外側から前記鍵穴を臨む開き角度だけ施錠状態のまま回動し、鍵穴が外側に臨んだ錠前Ａを合鍵を使って施解錠操作すればよく、パネル間の目地部を利用して鍵棒の先端を目地部の狭い隙間に通して施解錠する操作が必要にならない構成であるため、鍵棒の先端が誤って目地部の狭い隙間の両縁に衝突して目地部が傷だらけになるようなこともなく、点検口周りの美的外観が悪化するのを防止することができる。   On the other hand, in the illustrated embodiment, when the door D is unlocked, the door D is rotated in the locked state by the opening angle facing the keyhole from the outside, and the lock A with the keyhole facing the outside is locked and unlocked using the key. It is only necessary to use the joint between the panels so that the operation of locking and unlocking the tip of the key stick through the narrow gap in the joint is not necessary. It is possible to prevent the aesthetic appearance around the inspection port from deteriorating without causing the joint portion to be damaged by colliding with both edges.
