この考案は上記の欠点を解消するもので、引き戸の開閉
機構の動作角度とは関係なく係合動作する係合装置を備
えたエレベータ用ドアー装置を提供しようとするもので
ある。This invention solves the above-mentioned drawbacks and provides an elevator door device equipped with an engaging device that engages independently of the operating angle of the sliding door opening/closing mechanism.
以下、第４図〜第７図によってこの考案の一実施例を説
明する。An embodiment of this invention will be described below with reference to FIGS. 4 to 7.
図中、第１〜第３図と同符号は相当部分を示し、８は両
端がそれぞれレバー５の下端及び引き戸３に枢着された
リンク、７は係合装置で、７ａは引き戸３に固定された
係合装置７の固定板、１１は中間部が固定板７ａの上部
に枢着された第１平行リンクからなる作動位置で一端に
はローラ１１ａが枢着しである。In the figure, the same reference numerals as those in Figures 1 to 3 indicate corresponding parts, 8 is a link whose both ends are pivoted to the lower end of the lever 5 and the sliding door 3, 7 is an engagement device, and 7a is fixed to the sliding door 3. The fixing plate 11 of the engaging device 7 is in an operating position where the middle part is a first parallel link pivotally attached to the upper part of the fixing plate 7a, and a roller 11a is pivotally attached to one end.
１２は一端が固定板７ａの下部に枢着された第２平行リ
ンク、７ｂは係合装置７の可動板で、上板には作動装置
１１の他端が、下部には第２平行リンク１２の他端がそ
れぞれ枢着されている。12 is a second parallel link whose one end is pivoted to the lower part of the fixed plate 7a, 7b is a movable plate of the engagement device 7, the other end of the actuating device 11 is attached to the upper plate, and the second parallel link 12 is attached to the lower portion. The other ends of each are pivotally connected.
７ｄは両端がそれぞれ可動板７ｂ、引き戸３に保持され
た引張りコイルばねからなる付勢体、１３は出入口２の
上縁部に固定されてローラｌｌａに対応したカムである
。Reference numeral 7d designates a movable plate 7b at both ends, and a biasing body consisting of a tension coil spring held by the sliding door 3. Reference numeral 13 designates a cam fixed to the upper edge of the entrance/exit 2 and corresponding to the roller lla.
すなわち、引き戸３の戸閉時にはローラｌｌａがカム１
３に押圧されて可動板７ｂは付勢体７ｄの付勢力に抗し
て上昇位置にあり係合装置７は拡幅して係合体１０．１
０’に対して非係合位置にある。That is, when the sliding door 3 is closed, the roller lla moves against the cam 1.
3, the movable plate 7b is in the raised position against the biasing force of the biasing body 7d, and the engaging device 7 is widened and the movable plate 7b is pushed to the engaging body 10.1.
It is in a disengaged position with respect to 0'.
そして引き戸３の戸開によってローラ１１ａがカム１３
から離脱して付勢体７ｄの付勢力により第４図において
作動装置１１、第２平行リンク１２が反時計方向へ回動
し可動板７ｂが下降する。Then, when the sliding door 3 is opened, the roller 11a is moved to the cam 13.
The actuating device 11 and the second parallel link 12 are rotated counterclockwise in FIG. 4 due to the urging force of the urging member 7d, and the movable plate 7b is lowered.
これによって係合体１０．１０’が固定板７ａと可動板
７ｂにより挟圧されて係合装置７が係合動作する。As a result, the engaging body 10, 10' is pressed between the fixed plate 7a and the movable plate 7b, and the engaging device 7 performs an engaging operation.
この状態で引き戸３と乗場の戸が一緒に戸開される。In this state, the sliding door 3 and the landing door are opened together.
そして戸閉されると戸閉直前においてローラｌｌａがカ
ム１３に係合し作動装置１１、第２平行リンク１２が時
計方向へ回動し係合装置７は拡幅して非保合状態となる
。Then, when the door is closed, the roller lla engages with the cam 13 just before the door is closed, the actuating device 11 and the second parallel link 12 rotate clockwise, and the engaging device 7 widens and enters the non-engaged state.
このように係合装置７はリンク８の回動動作に関係なく
係合及び非係合動作するので、レバー５、リンク８の回
動角度を自由に設定することができる。As described above, since the engagement device 7 engages and disengages independently of the rotational movement of the link 8, the rotational angle of the lever 5 and the link 8 can be set freely.
また、回動角度を自由に設定することによって出入口２
の幅寸法、すなわち引き戸３の開閉行程の長短によって
走行抵抗が変化することを少なくすることができて、円
滑に開閉動作するドアー装置が得られる。In addition, by freely setting the rotation angle, the entrance 2
It is possible to reduce the change in running resistance due to the width dimension of the sliding door 3, that is, the length of the opening/closing stroke of the sliding door 3, and thus a door device that smoothly opens and closes can be obtained.
なお、この実施例ではカム１３によりローラｌｌａを介
して引き戸３が押し下げられるので引き戸３の浮き上り
現象を防ぐことができる。In this embodiment, since the sliding door 3 is pushed down by the cam 13 via the roller lla, it is possible to prevent the sliding door 3 from floating up.
また、可動板７ｂが下降して係合動作するので、付勢体
７ｄが破断しても、可動板７ｂは自重により下降するの
で係合作用を直ちに喪失することがない。Moreover, since the movable plate 7b descends to perform the engagement operation, even if the biasing body 7d breaks, the movable plate 7b will descend due to its own weight, so that the engagement action will not be immediately lost.
また、カム１３の配置が容易であって適宜に大きくする
ことができるので可動板１ｂの変位量、すなわち保合装
置７の拡幅量を自由に設定することができ非保合時の係
合体１０．１０’との隙間を広くすることも容易であっ
てかご１が乗場を通過するときの安全性を向上させるこ
とができる。In addition, since the cam 13 is easy to arrange and can be enlarged appropriately, the amount of displacement of the movable plate 1b, that is, the amount of width expansion of the locking device 7 can be freely set, and the engaging body 10 when the locking device 7 is not locked can be set freely. It is also easy to widen the gap between the car 1 and the car 10', thereby improving safety when the car 1 passes through the landing.
