Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an elevator landing door, and more particularly to an elevator landing door that prevents the design of the door surface from being impaired due to the position of a keyhole base provided for unlocking the locking device of the landing door. It is something.

[Conventional technology]

Conventionally, various improvements have been made to unlocking devices for elevator hall doors, as shown in Japanese Utility Model Application Publication No. 162573/1983. Below, the landing door of a conventional elevator that has a keyhole base for unlocking the landing door is shown in the fifth example.
This will be explained with reference to FIGS. 8 to 8. FIG. 5 is a front view of the landing door seen from the landing side, where 1 is a three-sided frame and 2 is a double door door. A continuous pattern 3 is etched on the surface of the landing door 2 for the purpose of improving the design. 4 is a T that is installed at the top of the landing door 2 and is installed through it from the front side to the back side of the landing door 2.
With a keyhole cap having a shaped hole 4a, when a locking device 5 (to be described later) is to be unlocked during maintenance and inspection of an elevator, the locking device can be opened by manually pushing a key release rod 6 into the keyhole cap 4. 5 is unlocked so that the landing door 2 can be opened by hand. As can be seen in FIGS. 7 and 8, the lock device 5 includes an engaging protrusion 7 fixed to the back side of the upper edge of the three-sided frame 1, and a hanger fixed to the upper end of the landing 5j12. A locking member 10 is pivotally attached to the case 8 via a pivot pin 9 so as to be swingable in the vertical direction, and the distal end portion 10a of the locking member 10 always engages with the engaging protrusion 7 by its own weight. The member 10 is pushed upward in the vertical direction, and the engaging protrusion 7
and an unlocking lever 11 for unlocking the locked state between the locking member 10 and the locking member 10.
It is composed of. The unlocking lever 11 is vertically movable via a holding member 13 attached to a bent portion 12a of a reinforcing member 12 fixed to the back side of the upper end of the landing door 2 that fixes the hanger case 8. It is normally biased downward by a spring 14 so that its tip 11a does not come into contact with the lower end 10b of the locking member 10. Therefore, the locked state between the locking member 10 and the engaging protrusion 7 is maintained. Further, the unlocking lever 11 corresponds to the keyhole base 4 with its lower end 11b biased downward by a spring 14. Since the conventional landing door 2 is configured as described above,
During maintenance and inspection of the elevator, push the locking rod 6 through the keyhole base 4 from the surface side of the landing door 2, rotate it as shown by arrow A in FIG. By pushing up against 14, the locking member 10 is moved upward, unlocking the locking state with the engagement protrusion 7, and opening the landing door 2 to the left and right. money

[Problems to be solved by the invention]

Conventional elevator landing doors are constructed as described above, so the keyhole base for unlocking the locking device installed on the landing door is a locking device installed on the back side of the door. In particular, there is a restriction that it must be placed at a position corresponding to the installation position of the unlocking lever. Therefore, if a continuous pattern such as an etching finish is applied to improve the design of the landing door as shown in Figure 5, h) the entire F hole opening will interfere with the above pattern, causing customers to turn around suddenly. There was a problem in that it had a negative effect on the design image and was undesirable in terms of design. This invention was made in order to solve the above-mentioned problems, and it is possible to place the keyhole base on the landing door in any position that will not affect the pattern on the surface of the landing door. The elevator landing door according to the present invention, which provides an elevator landing door that enables cuff locking of the locking device even when the door is moved and displaced, has a cuff lock of the locking device that is disposed on the back side of the landing door. A connecting member is provided on the rear side member of the landing door at a distance in the width direction of the landing door, one end of which is pivotally connected to the door, and the other end of which is connected to the unlocking lever. A keyhole cap is arranged corresponding to an arbitrary position along the longitudinal direction.

[Effect]

The connecting member according to the present invention has one end pivotally mounted to be swingable in the vertical direction, and the other end connected to the lower end of the unlocking lever of the locking device, so that the unlocking lever can be pushed upward. By pushing up an arbitrary position along the longitudinal direction of the connecting member, a pushing force can be transmitted to the unlocking lever, and the locking device can be unlocked. Therefore, there is no restriction that the keyhole cap must be placed opposite the lower end of the unlocking lever as in the past. By being able to arrange the keyhole base, if the position of the keyhole base has a negative effect on the landing door design, it becomes possible to easily change the position of the keyhole base.
