  • It is configured to push up and unlock the lock device 4 provided above the upper end of the landing door 1.
  • the lock device 4 is pivotally attached to an engaging projection 6 fixed to a hanger case 5 and a door hanger 7 fixed to the upper end of the landing door 1 via a pivot pin 8 so as to be vertically swingable.
  • One end portion is constituted by a locking member 9 which always engages with the engaging projection 6 by weight.
  • a connecting metal 10 is provided at the other end of the locking member 9 on the side opposite to the pivot pin 8.
  • FIGS. 1 to 4 first, since the unlocking lever 2 is not used, the lower end of the unlocking lever 2 which is in the way is cut 2a, or the unlocking lever 2 is moved. It is completely removed and removed (see Fig. 1). Next, at the position on the back side of the keyhole provided at the top of the existing landing door 1, an operating piece 12 having a keyhole base 11 into which a triangular key is inserted is inserted. Attach. An operation pin 14 is provided on the operation end side of the operation lever 13 fixed to the operation piece 12. Further, a trigger 15 for connecting the connecting metal 10 of the existing unlocking device and the operating pin 14 of the operating lever 13 is provided. The lower end of the trigger 15 is provided with an elongated hole 16 through which the operating pin 14 passes.
  • the operating pin 14 Since the operating pin 14 is disposed near the lower end of the elongated hole 16, as shown in FIG. 5, when the landing door 1 is normally opened and closed, the connecting metal 10 and the trigger are triggered. The movement of 15 is within the range of escape (margin) upward by the slot 16 provided in the trigger 15 and does not hit the operating pin 14. Therefore, the operating lever 13 does not rotate, and can be kept stationary in the horizontal position.

  • the connecting metal 10 is stroked in the direction of the arrow (downward direction) in FIG. 1 to be in the unlocked state as shown in FIG. Therefore, since the unlocking lever 2 of the existing unlocking device is not used, the triangular key is rotated and unlocked without changing the mounting position of the keyhole base of the landing door 1. It becomes possible to convert it into a lock device.
  • the operating lever 13 is stationary at the horizontal position due to the moment due to the mass imbalance of the left and right axes of its rotation axis and the rotation range limitation of the triangular keyhole cap 11. It is.
  • the engagement state of the lock device 4 is released, and the locking member 9 is moved upward through the pivot pin 8. Even if it is rocked and the coupling 10 and the trigger 15 move downward, The operating pin 14 is located substantially at the center of the elongated hole 16 provided in the trigger 15 and does not reach the point where the operating pin 14 is operated. For this reason, the operating lever 13 does not rotate, and can be kept stationary at the horizontal position.
  • the additional mass to the operating system of the unlocking device is only the mass of the trigger 15. Therefore, the influence of the modification on the magnitude of the force for operating the unlocking device can be suppressed to a very small one.
  • the elevator landing door unlocking device and its modification method according to the present invention are configured to operate the unlocking bar in the vertical direction to push up the unlocking lever and unlock the landing door locking device.
  • the elevator landing door which is modified from an unlocking device for the elevator landing door to a unlocking device that rotates and unlocks a triangular key instead of operating the key in the vertical direction Suitable for repair work of unlocking device.
