By rapidly sliding to the position, the locked piece 8 is detached from the locking piece 7 on the fixed frame 3 side and is held in the unlocked position. Since the sliding rod 9 is held in the unlocked position, the opening 1 such as the window opening is opened by simply moving the end movable frame 6a of the opening / closing partition 2, 12, 22 to the open side, and the indoor A person can easily escape and can easily perform rescue work from the outside.

請求項２に係る発明によれば、スライド杆９が解錠位置に戻った時にヒーター１３の作動が停止するから、ヒーター１３の継続加熱作動による危険性を回避できる。   According to the second aspect of the invention, since the operation of the heater 13 is stopped when the slide rod 9 returns to the unlocked position, the danger due to the continuous heating operation of the heater 13 can be avoided.

以下に本発明の好適な実施形態を図面に基づいて説明すると、図１の(a) は開閉仕切具として使用した面格子が閉鎖位置にある状態を室内側から見た正面図であり、(b) は同面格子が一部開放位置にある状態の正面図である。この図１の(a) ，(b) において、１は建物の窓開口部で、この窓開口部１内に、開閉仕切具としての面格子２が配設されている。３は窓開口部１内の一端部に固定された固定枠で、この固定枠３と、面格子２の端部可動枠６ａとの間に、面格子２を閉鎖位置に施錠するための開閉仕切具施錠機構４が介装されている。   A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 (a) is a front view of a state in which a surface lattice used as an opening / closing partition is in a closed position, as viewed from the indoor side. b) is a front view of a state in which the coplanar lattice is partially in the open position. In FIGS. 1A and 1B, reference numeral 1 denotes a window opening of a building, and a surface lattice 2 as an opening / closing partition is disposed in the window opening 1. Reference numeral 3 denotes a fixed frame fixed to one end in the window opening 1. Between the fixed frame 3 and the end movable frame 6 a of the surface lattice 2, an opening / closing for locking the surface lattice 2 in a closed position. A partition locking mechanism 4 is interposed.

開閉仕切具としての面格子２は、例えば周知構造のスライド式面格子で、窓開口部１に固定して取り付けられる上下一対の中空状ガイドレール５，５と、両ガイドレール５，５上にこれを横切るように配置され且つガイドレール５の長手方向に並列状に配列される多数の格子６…と、ガイドレール５の中空部内に挿通される筒状部（図示省略）を有してガイドレール５にスライド可能に係嵌されると共に各格子６に固定されるスライダー（図示省略）と、このスライダーを介して格子６を所定間隔おきに連結固定する紐状体（図示省略）とからなり、紐状体は、各ガイドレール５の中空部内に挿通させると共に各スライダーの筒状部内に挿通させ、各スライダーは、その筒状部をかしめることによって紐状体の所定位置に固定させる。   The surface grid 2 as an open / close partition is, for example, a slide-type surface grid having a well-known structure, and is mounted on a pair of upper and lower hollow guide rails 5 and 5 fixed to the window opening 1 and on both guide rails 5 and 5. A guide having a plurality of lattices 6 arranged so as to cross the guide rail 5 and arranged in parallel in the longitudinal direction of the guide rail 5 and a cylindrical portion (not shown) inserted into the hollow portion of the guide rail 5. The slider 5 is slidably engaged with the rail 5 and is fixed to each grid 6 (not shown), and a string-like body (not shown) for connecting and fixing the grid 6 at predetermined intervals via the slider. The string-like body is inserted into the hollow portion of each guide rail 5 and the cylindrical portion of each slider, and each slider is fixed at a predetermined position of the string-like body by caulking the cylindrical portion.

そして、多数の格子６…のうち固定枠３に当接する格子６を端部可動枠６ａとし、この端部可動枠６ａと反対側の端部にある格子６を上下ガイドレール５，５の夫々端部に固定した状態で、端部可動枠６ａを固定枠３に接近するようにスライドさせると、隣接する格子６が紐状体で順次牽引されて一定間隔毎に配列され、図１の(a) のように窓開口部１が閉鎖される。また、端部可動枠６ａを固定枠３から離れる方向にスライドさせると、図１の(b) に示すように他の格子６も順次開放方向へ押されて、格子６全体が他端側へ片寄り状態に収縮し、窓開口部１が開放されるようになっている。   Of the multiple grids 6..., The grid 6 that contacts the fixed frame 3 is an end movable frame 6a, and the grid 6 at the end opposite to the end movable frame 6a is the upper and lower guide rails 5 and 5, respectively. When the end movable frame 6a is slid so as to approach the fixed frame 3 while being fixed to the end, the adjacent lattices 6 are sequentially pulled by the string-like body and arranged at regular intervals. The window opening 1 is closed as shown in a). When the end movable frame 6a is slid in the direction away from the fixed frame 3, the other lattices 6 are sequentially pushed in the opening direction as shown in FIG. 1 (b), and the entire lattice 6 is moved to the other end side. The window opening 1 is opened by contracting to the offset state.

上記面格子２を閉鎖位置に施錠する開閉仕切具施錠機構４は、窓開口部１の固定枠３と面格子２の端部可動枠６ａとの間に介装されたもので、以下にこの施錠機構４の構造及び作用について説明する。   The opening / closing partition locking mechanism 4 that locks the surface lattice 2 in the closed position is interposed between the fixed frame 3 of the window opening 1 and the end movable frame 6a of the surface lattice 2. The structure and operation of the locking mechanism 4 will be described.

この施錠機構４は、図２の(a) に示すように、面格子２の端部可動枠６ａの上下２箇所に取り付けられた係止片７と、この係止片７に対し係脱自在な被係止片８を上下両端部に有し、窓開口部１側の固定枠３内で係止片７が被係止片８に係止する施錠位置と係止片７が被係止片８に対し離脱する解錠位置とにわたってスライド自在に支持されるスライド杆９と、このスライド杆９を解錠位置に付勢するように固定枠３の上端部とスライド杆９の上端部との間に介装されたコイルバネ１０と、このコイルバネ１０の付勢力に抗してスライド杆９を施錠位置に保持するように引張する熱可塑性樹脂製の施錠位置保持索１１と、この保持索１１に接するように配置されると共に熱又は煙を検知する火災感知器Ｋに連動して設けられたヒーター１３とからなるもので、ヒーター１３は、火事等の緊急時に火災感知器Ｋが熱又は煙を検知した検知信号により作動して施錠位置保持索１１を溶断し、それによりスライド杆９が解錠位置に急速スライドして解錠されるようになっている。   As shown in FIG. 2 (a), the locking mechanism 4 includes a locking piece 7 attached to two upper and lower portions of the end movable frame 6a of the surface lattice 2, and the locking piece 7 can be freely engaged and disengaged. Lock pieces 8 at both upper and lower ends, and a locking position where the lock pieces 7 are locked to the lock pieces 8 in the fixed frame 3 on the window opening 1 side and the lock pieces 7 are locked A slide rod 9 that is slidably supported over an unlocking position where it is separated from the piece 8, and an upper end portion of the fixed frame 3 and an upper end portion of the slide rod 9 so as to bias the slide rod 9 to the unlocked position. A coil spring 10 interposed therebetween, a locking position holding cable 11 made of thermoplastic resin that pulls the slide rod 9 to hold it in the locking position against the urging force of the coil spring 10, and the holding cable 11 The heater 13 provided in conjunction with the fire detector K which is arranged in contact with the fire and detects heat or smoke In the event of an emergency such as a fire, the heater 13 is actuated by a detection signal detected by the fire detector K to detect heat or smoke and melts the locking position holding cable 11 so that the slide rod 9 is in the unlocked position. It is designed to be unlocked by sliding quickly.

上記施錠機構４の構造について更に詳細に説明すると、スライド杆９は、図２の(b) ，(c) に示すように、固定枠３に設けられた固定ガイド部１４，１５間にスライド自在に配置されていると共に、固定ガイド部１４に固定された取付軸１６がスライド杆９の下部側に設けられた長孔１７に挿通されることによって所定ストロークだけ上下にスライドできるようになっている。またスライド杆９の上部側には取付軸１８が固定され、この取付軸１８は固定ガイド部１４に設けられた長孔１９に挿通されている。   The structure of the locking mechanism 4 will be described in more detail. The slide rod 9 is slidable between fixed guide portions 14 and 15 provided on the fixed frame 3 as shown in FIGS. 2 (b) and 2 (c). The mounting shaft 16 fixed to the fixed guide portion 14 is inserted into a long hole 17 provided on the lower side of the slide rod 9 so that it can slide up and down by a predetermined stroke. . A mounting shaft 18 is fixed to the upper side of the slide rod 9, and the mounting shaft 18 is inserted into a long hole 19 provided in the fixed guide portion 14.

また図２の(a) 〜(c) に示すように、下部側の取付軸１６と上部側の取付軸１８との中間部にはベークライト等の絶縁性材料からなるヒーター取付台２０が設置され、この取付台２０にヒーター１３が取り付けられている。そして、このヒーター取付台２０を挟んで上下に位置する上下両取付軸１６，１８に、施錠位置保持索１１が、ヒーター１３に当接するように掛け渡されるようになっている。   Further, as shown in FIGS. 2A to 2C, a heater mounting base 20 made of an insulating material such as bakelite is installed at an intermediate portion between the lower mounting shaft 16 and the upper mounting shaft 18. The heater 13 is attached to the mounting base 20. Then, the locking position holding rope 11 is stretched over the upper and lower mounting shafts 16 and 18 positioned above and below the heater mounting base 20 so as to contact the heater 13.

施錠位置保持索１１は、釣糸のようなナイロン製の比較的細い紐状体からなるもので、その両端部には図２の(b) ，(c) に概略示すように、取付軸１６，１８に嵌め入れるための金属製の取付リングＲが取り付けられている。   The locking position holding cable 11 is made of a relatively thin string-like body made of nylon such as a fishing line, and is attached to both ends thereof with attachment shafts 16, as schematically shown in FIGS. 2 (b) and 2 (c). A metal attachment ring R for fitting into 18 is attached.

この施錠位置保持索１１は、スライド杆９を解錠位置に付勢するコイルバネ１０のバネの付勢力に抗してスライド杆９を施錠位置に保持するもので、その取付けにあたっては、図２の(a) ，(b) に示すように、コイルバネ１０によって上向きに引っ張られているスライド杆９を、その付勢力に抗して下向きに引っ張りながら、スライド杆９の被係止片８が端部可動枠６ａ側の係止片７と係合して施錠状態となるように、施錠位置保持索１１の両端部の取付リングＲ，Ｒを、固定ガイド部１４側の取付軸１６とスライド杆９側の取付軸１８とに嵌め入れる。   This locking position holding cable 11 holds the slide rod 9 in the locked position against the urging force of the coil spring 10 that urges the slide rod 9 to the unlocked position. As shown in (a) and (b), while the slide rod 9 pulled upward by the coil spring 10 is pulled downward against the urging force, the locked piece 8 of the slide rod 9 has an end portion. The mounting rings R and R at both ends of the locking position holding cable 11 are connected to the mounting shaft 16 on the fixed guide portion 14 side and the slide rod 9 so as to be engaged with the locking piece 7 on the movable frame 6a side to be locked. Fit into the side mounting shaft 18.

この際、スライド杆９の被係止片８が端部可動枠６ａ側の係止片７に的確に係合して確実に施錠位置を保持させる必要があるため、保持索１１の長さを適当に選択すると共に、取付軸１６，１８にナット２１を螺合して、このナット２１を適宜移動することにより、スライド杆９の施錠位置に的確に調整するようにする。   At this time, since the locked piece 8 of the slide rod 9 needs to be accurately engaged with the locking piece 7 on the end movable frame 6a side to securely hold the locking position, the length of the holding rope 11 is increased. The nut 21 is screwed onto the mounting shafts 16 and 18 and the nut 21 is appropriately moved so that the slide rod 9 is accurately adjusted to the locking position.

また、図１の(a) 〜(c) において、ＬＳはリミットスイッチで、火事等の緊急時に火災感知器Ｋが熱又は煙を検知した検知信号によりヒーター１３が作動して施錠位置保持索１１を溶断し、スライド杆９が解錠位置に戻った時に、ヒーター１３への通電を停止するものである。即ち、このリミットスイッチＬＳは、スライド杆９を施錠位置に保持していた施錠位置保持索１１が、ヒーター１３の加熱により溶断してスライド杆９が解錠位置に戻った時に、後述するようにスライド杆９と一体の取付軸１８が作動レバー３０を押して、ヒーター１３への通電回路が開き、ヒーター１３の作動を停止するようになっている。   Further, in FIGS. 1A to 1C, LS is a limit switch, and the heater 13 is activated by a detection signal detected by the fire detector K in the event of an emergency such as a fire, and the locked position holding cable 11 is operated. When the slide rod 9 is returned to the unlocked position, the energization to the heater 13 is stopped. That is, this limit switch LS is described later when the lock position holding cable 11 that has held the slide rod 9 in the locked position is melted by the heating of the heater 13 and the slide rod 9 returns to the unlocked position. The mounting shaft 18 integrated with the slide rod 9 pushes the operation lever 30, opens the energization circuit to the heater 13, and stops the operation of the heater 13.

図３は火災感知器Ｋとヒーター１３とリミットスイッチＬＳとマグネットリレー式制御部２３と電源２４とからなる電気回路図を示す。火災感知器Ｋは、屋内の所要箇所に設置されている既設の火災感知器で、熱又は煙を検知し、この検知信号によって警報音を鳴らすもので、この検知信号はまた、制御部２３によってヒーター１３を加熱作動するようになっている。電源２４には、直流電源としての乾電池又はＡＣアダプターが使用され、この電源２４は、図２には示していないが、固定枠３内部の所要箇所に収納されるか、固定枠３外の室内所要箇所に設置されるようになっている。   FIG. 3 is an electric circuit diagram including the fire detector K, the heater 13, the limit switch LS, the magnet relay type control unit 23, and the power source 24. The fire detector K is an existing fire detector installed at a required location in the room, detects heat or smoke, and sounds an alarm sound by this detection signal. This detection signal is also sent by the control unit 23. The heater 13 is heated. As the power source 24, a dry battery or an AC adapter as a DC power source is used. This power source 24 is not shown in FIG. 2, but is housed in a required location inside the fixed frame 3 or a room outside the fixed frame 3. It is designed to be installed at the required location.

次に、上記のような構成よりなる開閉仕切具施錠機構４の作用について説明する。   Next, the operation of the opening / closing partition locking mechanism 4 configured as described above will be described.

平常時は、スライド杆９は、施錠位置保持索１１によって、図２の(a) ，(b) に示すようにコイルバネ１０のバネの付勢力に抗して施錠位置に保持され、しかして面格子２は、この施錠位置における端部可動枠６ａ側の係止片７と固定枠３側の被係止片８との係止作用によって、図１の(a) に示す閉鎖位置に施錠されている。   Under normal conditions, the slide rod 9 is held in the locked position against the urging force of the coil spring 10 by the locking position holding cable 11 as shown in FIGS. 2 (a) and 2 (b). The lattice 2 is locked in the closed position shown in FIG. 1A by the locking action of the locking piece 7 on the end movable frame 6a side and the locked piece 8 on the fixed frame 3 side in this locking position. ing.

そして、火災発生時等の緊急時に火災感知器Ｋが熱又は煙を検知すると、その検知信号によってヒーター１３が加熱作動し、その加熱によりナイロン製の施錠位置保持索１１が図２の(c) に示すように溶断する。施錠位置保持索１１が溶断すると、スライド杆９は、コイルバネ１０の付勢力によって自動的に施錠位置から解錠位置へと急速スライドする。即ち、施錠位置保持索１１の溶断によって、スライド杆９が上方側（解錠位置側）へ急速スライドして、被係止片８が図２の(a) の仮想線で示すように固定枠３側の係止片７から離脱し、スライド杆９は解錠位置に保持される。   When the fire detector K detects heat or smoke in an emergency such as the occurrence of a fire, the heater 13 is heated by the detection signal, and the nylon lock position holding cable 11 is heated by the heating, as shown in FIG. Fusing as shown. When the locking position holding cable 11 is fused, the slide rod 9 is automatically slid from the locking position to the unlocking position automatically by the biasing force of the coil spring 10. That is, by the fusing of the locking position holding cable 11, the slide rod 9 is rapidly slid upward (unlocked position side), and the locked piece 8 is fixed to the fixed frame as indicated by the phantom line in FIG. The slide bar 9 is disengaged from the locking piece 7 on the third side, and is held in the unlocked position.

スライド杆９が解錠位置に保持されているから、面格子２の端部可動枠６ａを固定枠３から離れる方向せスライドさせれば、図１の(b) に示すように他の格子６も順次開放方向へ押されて、格子６全体が他端側へ片寄り状態に収縮し、窓開口部１が開放されて、ここから緊急脱出することができる。この面格子２の開放操作は、室内側、室外側の何れの側からでも行なうことができる。   Since the slide rod 9 is held in the unlocked position, if the end movable frame 6a of the surface lattice 2 is slid away from the fixed frame 3, the other lattice 6 as shown in FIG. Are sequentially pushed in the opening direction, and the entire lattice 6 is contracted to the other end side so that the window opening 1 is opened, and emergency escape can be performed from here. The opening operation of the surface lattice 2 can be performed from either the indoor side or the outdoor side.

また、施錠位置保持索１１がヒーター１３の加熱により溶断してスライド杆９が解錠位置に戻る時には、図２の(b) 及び(c) を参照すれば分かるように、スライド杆９に固定された取付軸１８がリミットスイッチＬＳの作動レバー３０を押し、それにより図３の仮想線で示すようにヒーター１３への通電回路を開閉するスイッチ片２５が開動し、このスイッチ片２５の開動によってヒーター１３の作動が停止する。   When the lock position holding cable 11 is melted by the heating of the heater 13 and the slide rod 9 returns to the unlocked position, as shown in FIGS. 2 (b) and (c), it is fixed to the slide rod 9. The attached mounting shaft 18 pushes the operating lever 30 of the limit switch LS, thereby opening the switch piece 25 that opens and closes the energization circuit to the heater 13 as shown by the phantom line in FIG. The operation of the heater 13 is stopped.

このようにスライド杆９が解錠位置に戻った時にヒーター１３の作動が停止するから、ヒーター１３の継続加熱作動による危険性を回避することができる。   Thus, since the operation of the heater 13 stops when the slide rod 9 returns to the unlocked position, the danger due to the continuous heating operation of the heater 13 can be avoided.

図４は開閉仕切具として引き違い戸１２を使用した場合を示すもので、この引き違い戸１２が閉鎖位置にある状態を室内側から見た正面図である。引き違い戸１２は、建物の出入り口（開口部）１に建て込まれた２枚の引き戸１２ａ，１２ｂからなるもので、この実施形態では一方の引き戸１２ａがスライド自在で、他方の引き戸１２ｂは固定されているものとする。   FIG. 4 shows a case where the sliding door 12 is used as an opening / closing partition, and is a front view of the sliding door 12 in a closed position as viewed from the indoor side. The sliding door 12 is composed of two sliding doors 12a and 12b built in a doorway (opening) 1 of the building. In this embodiment, one sliding door 12a is slidable and the other sliding door 12b is fixed. It is assumed that

しかして、建物の出入り口１内の一端部に固定された固定枠３と、引き戸１２ａの端部可動枠６ａとの間に、引き戸１２ａを閉鎖位置に施錠するための開閉仕切具施錠機構４が介装されている。この開閉仕切具施錠機構４の構造及び作用については、図１〜図３によって説明した面格子２の施錠機構４とほとんど同様であるため、説明を省略する。   Thus, an opening / closing partition locking mechanism 4 for locking the sliding door 12a in the closed position is provided between the fixed frame 3 fixed to one end in the entrance 1 of the building and the end movable frame 6a of the sliding door 12a. It is intervened. The structure and operation of the opening / closing partition locking mechanism 4 are almost the same as the locking mechanism 4 of the surface lattice 2 described with reference to FIGS.

図５は、開閉仕切具として扉２２（開き戸、ドア）を使用した場合の実施形態を示す。この扉２２が閉鎖位置にある状態を室内側から見た正面図である。この扉２２は建物の出入り口（開口部）１に一端部を蝶番２６で枢着して開閉自在としたもので、出入り口１内の一端部に固定された固定枠３と、扉２２の端部可動枠６ａとの間に、扉２２を閉鎖位置に施錠するための開閉仕切具施錠機構４が介装されている。図５において、２７は扉２２の把手を示す。この開閉仕切具施錠機構４の構造及び作用については、図１〜図３によって説明した面格子２の施錠機構４とほとんど同じであるため、その説明を省略する。   FIG. 5 shows an embodiment in which a door 22 (a hinged door, door) is used as an opening / closing partition. It is the front view which looked at the state in which this door 22 exists in a closed position from the room inner side. The door 22 is configured to be freely opened and closed by pivotally attaching one end to a doorway (opening) 1 of the building with a hinge 26, and a fixed frame 3 fixed to one end in the doorway 1 and an end of the door 22. An opening / closing partition locking mechanism 4 for locking the door 22 in the closed position is interposed between the movable frame 6a. In FIG. 5, reference numeral 27 denotes a handle of the door 22. Since the structure and operation of the opening / closing partition locking mechanism 4 are almost the same as the locking mechanism 4 of the surface lattice 2 described with reference to FIGS. 1 to 3, description thereof is omitted.

以上の実施形態では、開閉仕切具として、面格子、引き違い戸及び扉（開き戸、ドア）について説明したが、本発明の開閉仕切具施錠機構４は、引き込みタイプの開閉仕切具、一部取外しタイプの開閉仕切具等にも適用可能である。更にまた、開閉仕切具としては、シャッターを使用できるものである。また開閉仕切具としての面格子は、この実施形態に示したスライドタイプのもの以外の例えば開きタイプなど各種の面格子を使用できる。   In the above embodiment, the surface lattice, the sliding door, and the door (the hinged door, the door) have been described as the opening / closing partition. However, the opening / closing partition locking mechanism 4 of the present invention is a retractable opening / closing partition, partly removed. It can also be applied to a type of opening / closing partition. Furthermore, a shutter can be used as the opening / closing partition. Further, as the surface grid as the opening / closing partition, various surface grids such as an open type other than the slide type shown in this embodiment can be used.

また実施形態では、係止片７を端部可動枠６ａ側に取り付け、被係止片８を有するスライド杆９を固定枠３側に設けたが、開閉仕切具によっては、端部可動枠６ａ側に被係止片８を有するスライド杆９を設け、固定枠３側に係止片７を取り付けてもよい。   In the embodiment, the locking piece 7 is attached to the end movable frame 6a side, and the slide rod 9 having the locked piece 8 is provided on the fixed frame 3 side. However, depending on the opening / closing partition, the end movable frame 6a is provided. A slide rod 9 having a latched piece 8 may be provided on the side, and the latch piece 7 may be attached to the fixed frame 3 side.
