前記第１の平板７１はレール１０の中央付近に結合される。この場合、第１の平板７１とレール１０との結合はボルト８０により行われる。 The first flat plate 71 is coupled near the center of the rail 10. In this case, the first flat plate 71 and the rail 10 are coupled by the bolt 80.
前記第２の平板７２は第１の平板７１に連設され、第１の平板７１において直角に折り曲げられ、ボルト結合孔が穿設される。 The second flat plate 72 is connected to the first flat plate 71, is bent at a right angle on the first flat plate 71, and is provided with a bolt coupling hole.
前記ボルト８０はボルト結合孔にねじ込まれる。この場合、前記第１の係止部４０は前記ボルト結合孔と対応する位置に孔が穿設されてボルト８０と螺合する。 The bolt 80 is screwed into the bolt coupling hole. In this case, the first locking portion 40 has a hole formed at a position corresponding to the bolt coupling hole and is screwed with the bolt 80.
前記リレー接触子９０はレール１０の中央付近に設けられる。この場合、リレー接触子９０は両側に接触点９１を備え、左扉開閉板２０と右扉開閉板３０に設けられる接触点２０ａ、３０ａと当接する場合の接触の有無を検出する。このリレー接触子９０は左扉開閉板２０と右扉開閉板３０が中央に位置することを判別してエレベーター扉が閉扉された状態に関する情報をエレベーター制御システム（図示せず）に伝える役割を果たす。 The relay contact 90 is provided near the center of the rail 10. In this case, the relay contact 90 includes contact points 91 on both sides, and detects the presence or absence of contact when contacting the contact points 20a, 30a provided on the left door opening / closing plate 20 and the right door opening / closing plate 30. The relay contact 90 plays a role of discriminating that the left door opening / closing plate 20 and the right door opening / closing plate 30 are located in the center and transmitting information on the state where the elevator door is closed to an elevator control system (not shown). .
以下、本発明の一実施の形態によるエレベーター扉開閉装置の駆動について説明する。 Hereinafter, driving of the elevator door opening and closing apparatus according to the embodiment of the present invention will be described.
最初に、エレベーターは、これを利用する者によって所望の階数に達した場合、左扉開閉板２０と右扉開閉板３０が、図１に示すように、閉扉状態にあり、図３に示すように、左扉開閉板２０と右扉開閉板３０がレール１０に沿って開扉されてエレベーター左扉（図示せず）と右扉（図示せず）を開扉する。エレベーター扉が再び閉扉される場合、回転掛止金具６０は中心軸６１を基準として回転し、左扉開閉板２０と右扉開閉板３０の固定状態を解放する。 First, when the elevator reaches a desired number of floors by a person using it, the left door opening / closing plate 20 and the right door opening / closing plate 30 are in a closed state as shown in FIG. 1, as shown in FIG. The left door opening / closing plate 20 and the right door opening / closing plate 30 are opened along the rail 10 to open the elevator left door (not shown) and the right door (not shown). When the elevator door is closed again, the rotation latch 60 rotates with respect to the central axis 61 to release the fixed state of the left door opening / closing plate 20 and the right door opening / closing plate 30.
この過程で、左扉開閉板２０と右扉開閉板３０が閉扉された状態を詳述すると、まず左扉開閉板２０と右扉開閉板３０はレール１０に沿って中央付近に位置する場合、回転掛止金具６０の第２の係止爪６３は第１の係止部４０の斜面に乗って摺動して第２の係止域５１に挿入される。このとき、回転掛止金具６０は中心軸６１を基準としてわずかな回転をする駆動をする。すると、右扉開閉板３０は回転掛止金具６０の第２の係止爪６３と第２の係止域５１との結合により固定状態を維持する。 In this process, the state in which the left door opening / closing plate 20 and the right door opening / closing plate 30 are closed will be described in detail. First, when the left door opening / closing plate 20 and the right door opening / closing plate 30 are located near the center along the rail 10, The second locking claw 63 of the rotary latch 60 is slid on the slope of the first locking portion 40 and inserted into the second locking area 51. At this time, the rotation latch 60 is driven to rotate slightly with respect to the central shaft 61. Then, the right door opening / closing plate 30 maintains the fixed state by the coupling of the second locking claw 63 and the second locking area 51 of the rotary latch 60.
これと同時に、回転掛止金具６０の第１の係止爪６２は第１の係止部４０の斜面に乗って摺動して第１の係止域４１に密着される。この場合、左扉開閉板２０は固定状態を維持する。 At the same time, the first locking claw 62 of the rotary latch 60 is slid on the slope of the first locking portion 40 and is in close contact with the first locking area 41. In this case, the left door opening / closing plate 20 maintains a fixed state.
すなわち、エレベーター扉が閉扉された状態では、左扉開閉板２０が回転掛止金具６０の第２の係止爪６３が第２の係止域５１に結合されて固定された状態を維持し、右扉開閉板３０が回転掛止金具６０の第１の係止爪６２が第１の係止域４１に結合されて固定された状態を維持する。 That is, in a state where the elevator door is closed, the left door opening / closing plate 20 maintains a state where the second locking claw 63 of the rotation latch 60 is coupled to the second locking area 51 and fixed. The right door opening / closing plate 30 maintains the state in which the first locking claw 62 of the rotary latch 60 is coupled and fixed to the first locking area 41.
ここで、本発明の一実施の形態によるエレベーター扉開閉装置は、左扉開閉板２０と右扉開閉板３０を移動させるワイヤー（図示せず）が途切れた状態でも、左扉開閉板２０と右扉開閉板３０が中央に固定された状態で位置するようにして誤作動状態でも扉が開扉される現象を防ぐことにより、人命被害が発生しないように安定性を向上させる。 Here, the elevator door opening / closing apparatus according to the embodiment of the present invention is configured so that the left door opening / closing plate 20 and the right door opening / closing plate 20 and the right door even when a wire (not shown) for moving the left door opening / closing plate 20 and the right door opening / closing plate 30 is interrupted. The door opening / closing plate 30 is positioned in a fixed state to prevent the door from being opened even in a malfunctioning state, thereby improving the stability so as not to cause human life damage.
