Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car ceiling device, and more particularly to an elevator car ceiling device that facilitates rescue work and maintenance inspection work.

[0002]

2. Description of the Related Art Related to the conventional elevator car ceiling device of this type, there is a technique disclosed in Japanese Utility Model Laid-Open No. 1-115670 and published technical report No. 92-15769. Further, FIG. 13 is a vertical cross-sectional view showing a conventional cab interior ceiling device of an elevator, in which a cab is provided with a ceiling trunk. In the figure, 1 is an elevator car room, 2 is a car floor, 3 is an openable / closable car door disposed at the entrance of the car room 1, 4 is a door closing girder located above the car door 3, and 5 is a car. A door-closing machine that opens and closes the door 3, 6 is a car frame pillar that forms a part of the exterior of the car room 1, 7 is an upper beam of the car frame, and 8
A car handrail arranged above the car room 1, 9 a ceiling trunk formed by extending the car room 1 upward, 10 a rescue exit arranged at the top of the ceiling trunk 9, 11 It is an opening / closing lid that opens and closes the rescue exit 10.

As described above, in order to load a long luggage or the like in the car room 1, the ceiling boot 9 of the car room 1 is provided in the car room 1 to secure the space in the car room 1. There is.

[0004]

However, in the above-described conventional elevator car cab ceiling apparatus, since the rescue port 10 is provided at the top of the ceiling trunk 9, the car floor 2 of the cab 1 is provided. The height of the rescue exit 10 was small, and the area of the rescue exit 10 was small. For this reason, when the passengers in the cab 1 are rescued, not only the rescue operation becomes difficult, but also there is a risk of falling into the hoistway. Further, although a car upper handrail 8 is provided for preventing falling when standing on the upper surface of the ceiling trunk 9, if the car upper handrail 8 is attached at an excessively high position, a gap or the like at the top of the elevator cannot be secured. There was a problem. For this reason, it is unavoidable to dispose at a relatively low position, and the effect of the car handrail 8 cannot be expected very much.

These problems also exist in the case of performing maintenance and inspection of various devices located above the ceiling outside the car, and it is necessary to solve these problems regardless of the presence or absence of the ceiling trunk 9. . Further, since the conventional ceiling trunk 9 is a fixed type integrally formed with the car room 1, regardless of whether long luggage or the like is loaded in the car room 1, there is always a space in the car room 1. However, the appearance and the transportation efficiency were not taken into consideration.

Therefore, an object of the present invention is to provide an elevator car ceiling device that can be easily and safely rescued even when it has a ceiling trunk, and at the same time, has a good appearance and a highly efficient elevator car. It is an object to provide a room ceiling device. It is another object of the present invention to provide an elevator cab ceiling device that can be easily and safely rescued and inspected even when it has no ceiling trunk.

Embodiments of the present invention will be described below. <First Embodiment> FIG. 1 is a longitudinal sectional view showing a normal state of an elevator cab ceiling device according to a first embodiment of the present invention.
FIG. 3 is a vertical cross-sectional view showing a state at the time of rescue work by the elevator car ceiling device of FIG. 1. This embodiment corresponds to the embodiments of the inventions of claims 1 and 2. In the figure, the same reference numerals and symbols as those of the above-mentioned conventional example indicate the same or corresponding components as those of the above-mentioned conventional example.

In the figure, reference numeral 12 is a ceiling trunk which is located above the cab 1 and is separate from the cab 1. The ceiling trunk 12 communicates with the cab 1. Reference numeral 13 is a moving device for moving the entire ceiling trunk 12 in the vertical direction along the cab 1, and by rotating a handle 13a provided outside the cab, a rack and a pinion gear (not shown) work, The ceiling trunk 12 moves up and down along the pinion gear frame 13b. At this time, the side surface of the ceiling trunk 12 is guided by the guide rollers 13c and smoothly moves up and down. Reference numeral 14 is a ramp provided along the side surface in the ceiling trunk 12, 15 is a rescue worker, 1
6 and 17 are passengers in the cab 1.

In the elevator cab ceiling device of this construction, during normal operation, the ceiling trunk 12 is moved upward as shown in FIG. That is,
A predetermined space is secured in the cab 1 by the ceiling trunk 12, and long luggage or the like can be loaded in the cab 1. When the elevator is stopped for some reason and the passengers 16 and 17 trapped in the cab 1 need to be evacuated to an emergency, as shown in FIG. 1, the handle 13a of the moving device 13 is rotated to move the ceiling trunk 12 downward. Thus, when the ceiling trunk 12 moves downward, the rescue port 10 and the trap 14 of the ceiling trunk 12 also move downward. Therefore, the ceiling trunk 1
