DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car entrance / exit device and, more particularly, to a car entrance / exit device suitable for a small elevator for a private residence.

[0002]

2. Description of the Related Art In a conventional small elevator for a private house, a machine room is provided at the top of the house.
-267281). Therefore, the car door of the car is guided by a sufficiently long sill until it is fully opened, as described in Japanese Patent Application Laid-Open No. 2-15891.

[0003]

In the above-mentioned prior art, a machine room is provided below a hoistway, and a control panel and a hoist are installed therein. However, this method cannot be applied to the case where the maintenance inspection door provided in the vehicle is opened and maintenance inspection is performed.

[0004] That is, the maintenance inspection door is opened with the car raised, and the maintenance and inspection work is performed while moving the car up and down while entering the machine room from the landing side or looking into the machine room from the landing side. If the car is accidentally lowered while the car is in operation, the threshold of the car may pass in front of a maintenance person, which is extremely dangerous.

It is an object of the present invention to provide an elevator car entrance / exit device which can ensure the safety of maintenance personnel during maintenance and inspection without impairing the opening / closing function of the car door.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a car door which moves horizontally to open and close a doorway of a car, a door closing door shoe and a door pocket side shoe provided at a lower portion of the car door. An elevator car entrance / exit device provided with a sill installed at a lower part of an entrance / exit of a car and engaging and guiding the two door shoes, wherein a length of the sill is longer than a full width of the entrance / exit, and a door closing end of the entrance / exit. This is achieved by forming the door shoe side door shoe to be shorter than the length from the side to the door pocket end side of the door when fully opened, and the door shoe on the door pocket side to be engaged with the sill end when fully opened.

[0007] With the above configuration, the length of the sill can be reduced to about the entire width of the car, so that even when the maintenance inspection door is opened, the sill of the car passes in front of the maintenance staff. It's safe and safe.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The car door 1 which opens and closes by moving the entrance and exit of the car 4 in the horizontal direction has a door-closing door shoe 3 at the bottom.
b and the door pocket side door shoe 3a are provided, and a sill 2 is provided on the car 4 side for guiding the door shoes 3a and 3b by engaging them inside.

On the other hand, a machine room is formed by installing a control panel 6 and a hoisting machine 7 at the bottom of a hoistway 5 on which the car 4 moves up and down. In addition, in the landing entrance frame 9 on the lowest floor, the car 4
A landing door is provided facing the car door 1, and a maintenance inspection door 8 communicating with the machine room is provided beside the landing door.

What is important in the above configuration is the length of the sill 2 and the shapes of the door shoes 3a and 3b.

That is, the length of the sill 2 is the length of the car door 1 overhanging from the door pocket side end 2a of the sill 2 when the car door 1 is fully opened at the door pocket side end 2a. Of the door, and shorter than the length from the door closed end of the door to the door pocket end of the door when fully opened.

Further, of the two door shoes 3a and 3b, the length of the door shoe end side door shoe 3a is set to the threshold 2 when the door is fully opened.
The door shoe 3b has the same length as that of the related art, and the door shoe 3b has the same length as that of the related art.

With the above configuration, the threshold 2 can be shortened. That is, when the car door 1 is fully opened, the door pocket end side of the car door 1 overhangs from the door pocket side end 2a of the short sill 2, but the door sack end side door shoe 3a becomes longer by the shortened sill 2, Since the door 2 is engaged with the door pocket side end 2a of the sill 2 with the margin g, there is no problem in opening and closing the car door 1.

Therefore, even if the car 4 is moved up and down while the maintenance staff is opening the maintenance door 8 and maintaining the control panel 6 and the like, the hatch side of the sill 2 as shown by hatching in FIG. Since the overhang of the end 2a is eliminated, the danger to the maintenance staff can be eliminated. FIG. 4 shows a door closing side door shoe 3 in place of the above long door pocket end side door shoe 3a.
A door pocket end side door shoe 3c having a required length is formed by connecting a plurality of ordinary door shoes equivalent to b, which is advantageous in that it is not necessary to prepare a particularly long door shoe.

[0015]

As described above, according to the present invention, it is possible to obtain an elevator car entrance / exit device capable of securing the safety of maintenance personnel during maintenance and inspection without impairing the opening / closing function of the car door.
