BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a landing door of an elevator used in a view elevator, for example.

[0002]

2. Description of the Related Art FIG. 4 is a view showing an example of a landing door of an elevator incorporated in a conventional general elevator, and is a view seen from a car side during an opening operation or a closing operation.

In FIG. 4, the door panels 23A and 23B are
The door panels 23A and 23B are suspended on a rail 2 provided laterally on a hanger case 1 via a pair of guide wheels 5 attached to a hanger 4 whose lower ends are fixed to the upper ends.

In these door panels 23A and 23B, a strip-shaped plate commonly referred to as a razor provided on a car door (not shown) located on the front side of these door panels 23A and 23B in FIG. 4 is a hanger 4 above the door panel 23B. By engaging with a door locking portion (not shown) provided in the car and opening / closing, the car door is opened / closed.

At this time, it is the door panel 23B that is directly driven by engaging with the razor of the car door.
A is subordinately driven by the belt 1a that moves with the opening / closing operation of the door panel 23B.

On the other hand, a pair of guide pieces 17 for guiding the door panels along the groove 6a of the sill 6 are vertically provided at the lower ends of the door panels 23A and 23B, as shown by broken lines in FIG. As shown at the bottom of FIG. 4, the door panel 23
In a general elevator, a predetermined gap is formed between the lower end surfaces of A and 23b and the upper surface of the sill 6.

However, in the elevator for observation, light enters from the outside into the hoistway of the elevator. Therefore, the light enters from the gap formed between the lower ends of the door panels 23A and 23B and the sill 6 as described above. And the design as seen from the landing side is degraded.

Therefore, in the elevator for the view, the lower end of the panel 23C in FIG. 5 and the space between the guide pieces 17 as shown in FIG. 6 showing the AA cross sectional enlarged detail view of FIG.
A light shielding plate 8 is provided over the outside of the guide piece 7 as described below.

That is, in FIG. 5 and FIG. 6, on the inner surface of the lower end of the door panel 23, a lower reinforcing member 9 formed from a slightly thick mild steel plate to have an L-shaped flexible section is welded to the inner surface of the door panel 23. It is laterally fixed via a plurality of welded studs and nuts (not shown). A weld nut 10 is provided in advance on the inner surface of the lower portion of the lower reinforcement 9 at a position corresponding to the machine screw 11 in FIG. 5, and the weld nut 10 is placed on the left side of FIG. Along with the upper ends of the pair of guide pieces 17 thus formed, the light shielding plate 8 is fixed by machine screws 11. The ends of both sides 8a of the light shielding plate 8 slightly overlap the folded-back portion 23a of the door panel 23C in order to cope with an error in the width of the door panel 23C, and the guide piece 17
In order to avoid the lower end of the guide piece 17, a U-shaped cutout portion 8b is formed in the joint fastening portion.

[0010]

However, in the elevator landing door configured as described above, a slight gap formed between the light-shielding plate 8 and the outer end of the left and right folded-back portions 23a, and the guide Light leaking to the hall side from the slight gaps formed on both sides of the piece 17 may deteriorate the design as seen from the hall side.

Therefore, it is conceivable to further reduce the gap formed between the light-shielding plate 8 and the outer inner surface of the left and right folded portions 23a, but the door panel 23C has a width made to form the folded portion 23a. Due to an error, the light shielding plate 8 may not be inserted when the width is manufactured to the minimum allowable value.

Further, if the gap between the both sides of the guide piece 17 and the cutout portion 8a of the light shielding plate 8 is reduced, the mounting accuracy of the light shielding plate 8 must be increased, so that it not only takes time to assemble, but also If the landing doors are slightly biased to the left or right, they may interfere with each other when the landing doors are closed to generate a collision sound, which may cause discomfort or anxiety to the passengers.

Therefore, an object of the present invention is to obtain an elevator landing door capable of preventing light from leaking from the hoistway to the landing side.
