本発明は、エレベータ乗場戸の解錠装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an unlocking device for an elevator landing door.
従来において特開昭５３−８９１４７号に提案されてい
るエレベータ乗場戸の解錠装置がある。There is a conventional elevator landing door unlocking device proposed in Japanese Patent Application Laid-Open No. 53-89147.
第４図はこの従来の解錠装置の構成を示す階床ドア閉状

に構成されている。FIG. 4 is an overall front view showing the structure of this conventional unlocking device when the floor door is closed, and FIG. 5 is a plan view thereof. In these figures, a landing door 1 is supported by a door hanger 2 on its upper part, and is configured to be able to move in both left and right directions in the figures to open and close.

A hook 5 is provided with an engaging portion that engages with a protruding portion of a switch case 7 fixed to the hook 5, and a locking device 6 is attached to a car door 11 facing each of these portions.
そして、保守点検等のために乗場戸１を乗場側から開閉

合状態を解除できるように構成されている。A key guide hole 9 is provided at the top of the first landing door 1 in order to open and close the landing door 1 from the landing side for maintenance inspection, etc., and a key (not shown) inserted through this key guide hole 9 is used to open and close the landing door 1 from the landing side. The hook 5 is configured to be disengaged from the protrusion of the switch case 7 by pushing the key guide bar 10 upward in the figure.

部１４との係合状態がはずれ、解錠状態となる。The locking device 6 transmits the electric power for opening and closing the electrically driven car door 11 to the landing door 1, and after releasing the engagement state of the hook 5, opens and closes the landing door 1 integrally with the car door 11. When the car lands on the floor, the engaging roller 3.4 and the locking bag F116 are in a state facing each other as shown in FIG. After this, the car door 11 is moved in the opening direction (second direction).
(to the left in the figure), and open from the position of the two-dot chain line A in Figure 3 to B.
When the engagement roller 4 reaches the position , the engagement roller 4 changes to a position where it contacts the other engagement roller 3 . Then, the engagement roller 3 rotates counterclockwise by a certain angle, and this rotation causes the tip of the hook 5 to rotate about the shaft 12 as shown by the two-dot chain line. This rotation of the tip of the hook 5 disengages the protrusion 13 provided on the switch case 7 from the engaging portion 14 at the tip of the hook, resulting in an unlocked state.

可能性が極めて大きく、安全対策上大きな問題点を有し
ている。However, in the conventional configuration, when the door is unlocked from the landing door side as described above, it remains unlocked until it is locked, so the landing door 1 can be opened regardless of the position of the car. Therefore, there is a very high possibility that a building manager or the like who is not familiar with elevators will unlock a landing door where no car is present and accidentally fall into the hoistway, which poses a major problem in terms of safety measures.
本発明の目的は、昇降路への転落事故を防止することが
できる安全性に優れたエレベータ乗場戸の解錠装置を提
供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator landing door unlocking device with excellent safety that can prevent an accident of falling into a hoistway.
本発明は、乗場戸側解錠操作時はフックに係合して乗場
戸を不完全開閉状態に制限する第２の係合部をフレーム
に設けると共に１乗場戸の裏面に前記第２の係合部の係
合状態を解除する解除機構を設けたものである。The present invention provides a frame with a second engaging part that engages with the hook and limits the landing door to an incompletely opened/closed state when the landing door side is unlocked, and the second engaging part is provided on the back surface of the first landing door. A release mechanism is provided to release the engaged state of the joint.
乗場戸は、乗場戸側からの解錠操作時は例えば人間の手
だけが入るスペースを残して不完全開閉状態に制限され
る。この状態で乗場戸裏面の解除機構を操作することに
よってはじめて全開状態にすることができる。When the landing door is unlocked from the landing door side, it is limited to an incompletely opened/closed state, leaving a space for only a human hand to enter, for example. In this state, the landing door can be fully opened only by operating the release mechanism on the back side of the landing door.
従って、解錠したことを忘れて乗場戸を開けても全開に
ならないため、昇降路に誤って転落してしまうような事
故を完全に防止することができる。Therefore, even if you forget to unlock the door and open the landing door, it will not open fully, making it possible to completely prevent accidents such as accidentally falling into the hoistway.
