Description

[Detailed description of the invention] This invention relates to elevator cars.

First, a conventional elevator car will be explained with reference to FIG.

In the figure, 1 is an elevator car that has an entrance 1a on the 1 side, 2 is a sill fixed to the front edge of the car 1, 3 is a lower cage placed under the car 1, and 4 and 4' are pillars fixed to both ends of the lower basket 3 and extending upward along the sides of the car compartment 1;
Reference numeral 5 denotes an earth odor connecting the upper ends of the pillars 4 and 4', and an elevator substructure 6 is connected to the middle part thereof. 7, 7' are angle-shaped mounting arms protruding from pillars 4, 4' above the car room 1 toward the entrance 1a, 8 is a girder fixed to the tips of the mounting arms 7, 7', and Ba is a rail fixed to girder 8, 9
, 9' are braces installed from both ends of the girder 8 toward both ends of the soil odor 5 to adjust the height of the girder 8 and support the weight of the girder 8, and 10 is a door for opening and closing the entrance 1a; is guided by the rail Ba, and the lower part is guided by a part of the threshold 2.

Reference numeral 11 denotes a drive machine installed on the girder 8 to open and close the door, and 12 a door device including the rail Ba) drive machine 11 and the like.

In other words, it requires a lot of manufacturing cost because it is composed of many parts such as the earthen 5, mounting arms 7, 7', girders 8, braces 9, etc.)
Not only that, but the installation and adjustment required a great deal of effort, and as a result, the whole system became expensive.

The present invention aims to eliminate the above-mentioned drawbacks and to provide an elevator car that is simply constructed and can be manufactured at low cost.

An embodiment of the present invention will be described below with reference to FIG.

In the figure, the same reference numerals as in FIG. 1 indicate corresponding parts, 131 is a car frame placed near the entrance 1a, and 4 and 4' are car frames that connect both ends of the sill 2 and both ends of the top 5. 13 pillars, 6
12 is a door device attached to the soil smell 5. That is, the door device 12 is attached to the top 5 and the door 6 is connected.

Therefore, it is possible to reduce the manufacturing cost of the parts that make up the elevator car, which is not small in number, and at the same time, the labor for installation and adjustment can be significantly reduced, resulting in an inexpensive elevator car. The desired results can be obtained especially in small elevators. As explained above, in the present invention, a door device for driving a door for opening and closing an entrance and a main rope for suspending a car are provided on an upper beam arranged above the entrance on the entrance side of a car room. As a result, the car can be constructed with a small number of parts, and the manufacturing cost of parts and the labor required for installation and adjustment can be reduced, and an inexpensive elevator car can be realized.
