Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-story elevator or an elevator in which two cars are arranged in one hoistway, and an elevator system in which the entrance and exit heights of a lower car and an upper car are different from each other. Regarding

[0002]

9 and 10 show, for example, Japanese Patent Publication No. 52-
It is a figure which shows the conventional elevator apparatus similar to the second-floor type elevator apparatus shown by 20740 publication, FIG. 9 is a front view of the elevator car, and FIG. 10 is a rear view of the hall where the car of FIG. 9 stops. In the figure, (1) is the hoistway (2)
Elevating body for moving up and down, (3) is the entrance (4) of height A shown in FIG.
The lower car, which is provided near the lower part of the lifting body (1), and (5) is higher than the entrance (4) of the lower car (3), and the entrance (6) of height B shown in FIG. Is an upper car arranged above the lower car (3) of the elevating body (1).

Reference numeral (7) is a lower door device for opening and closing the entrance (4) of the lower car (3). The engaging mechanism (8) is located at a height C shown in FIG. 9 from the floor of the lower car (3). It is provided. (9) is an upper door device that opens and closes the entrance (6) of the upper car (5).
An engagement mechanism (10) is provided at a height D shown in FIG. 9 from the floor (5).

The lower door device (7) and the upper door device
(9) is a well-known door device, each of which is a drive motor
(11), reduction gear (12), door rail (13), door hanger
(14), car door (15), link (1) to open and close the car door (15)
6), a safety edge (17) and a car sill (18).

The lower car (3) is provided in the hoistway (2) at (19).
A door device (21) for opening and closing the hall entrance (20) is provided at the hall where either the upper car (5) and the upper car (5) stop and face each other. The door device (21) is a well-known landing door device, and includes a hanger case (22), a door rail (23), a door hanger (24), an interlock hanging metal fitting (25), and an interlock latch (26). , Interlocking rope mechanism (27), landing door
(28), from the floor of the hall (19) installed in the hall door (28) Figure 1
It is composed of an engaging body mechanism (29) and a landing threshold (30) arranged at a height E shown in FIG.

The conventional elevator apparatus is constructed as described above. For example, when the elevator (1) moves up and down and the upper car (5) arrives at the required landing (19), a control unit (not shown) operates. Issue a door open command. This allows the upper door device (9)
Door rail (13) via a link (16) that opens and closes the reduction gear (12) and the car door (15) when the drive motor (11) of the
The car door (15) suspended on the door hanger (14) having rollers to roll around begins to open.

At this time, the engaging mechanism (1
0) engages with the engaging body mechanism (29) provided in the hall door (28) so that the car door (15) and the hall door (28) are engaged. Then, the interlocking metal fitting (25) and the interlock latch (26) are released by the door opening operation of the car door (15), and the car door (15) and the landing door (28) are electrically operated together. It is designed to be opened. Even when the lower car (3) arrives at the required landing (19), the door opening / closing operation similar to that for the upper car (5) is performed.

Further, the lower car (3) and the upper car (5) do not stop at a specific hall (19) and perform a door opening / closing operation, respectively, but as needed for any hall (19). It is designed to stop and open and close the door. The lower basket
The entrance and exit heights of (3) and the upper car (5) are set depending on the difference in the purpose of use of each car and the height between floors of the building in which the elevator device is installed.

[0009]

In the conventional elevator apparatus as described above, the entrance (4) of the lower car (3) and the entrance (6) of the upper car (5) are different in height from the floor. Engagement mechanism
The positions of (8) and (10) are different, such as the C position and the D position shown in FIG. Therefore, when the lower car (3) or the upper car (5) stops at the landing (19), the respective engagement mechanisms (8), (1)
If the vertical center position of (0) is aligned with the engaging mechanism (29) of the landing (19), at least one floor of the lower car (3) and the upper car (5) is the floor of the landing (19). There was a problem that it would not match.

In order to solve the above problems, the engagement mechanisms (8) and (10) are adjusted to compensate for the difference in height position of the engagement mechanisms (8) and (10) from the floor. It is possible to increase the vertical length. However, the door opening / closing operation is performed by engaging the engaging body mechanism (29) of the hall (19) at a position deviated from the longitudinal center of the engaging mechanisms (8), (10), so that the smoothness of the door opening / closing operation Will be damaged.

Further, the entrance (4) of the lower car (3) and the upper car
Even if the height of the entrance (6) of (5) is different, the engagement mechanism from the floor
It is conceivable to change the configurations of the lower door device (7) and the upper door device (9) so that the positions of (8) and (10) are the same. However, the lower door device (7) and the upper door device
This is not a good idea because it requires complicated steps for designing and manufacturing (9) and also makes maintenance work complicated.

The present invention has been made in order to solve such a problem, and when the entrance of the lower car and the entrance of the upper car have different heights, the lower car or the upper car normally stops at the landing. Another object of the present invention is to obtain an elevator device in which a door of a hall and a door of a car are engaged with each other and can be opened and closed together without difficulty.

Therefore, even if the height of the entrance of the lower car is different from the height of the entrance of the upper car, the lower car or the upper car stops in a normal state in which the floors coincide with each other in the landing, and the landing door and the car door are impossible. Instead of being engaged, they open and close together. This has the effect of smoothly opening and closing the doors of the hall and the doors of the car. Further, it is not necessary to change the configurations of the lower door device and the upper door device, and the design and manufacture of the lower door device and the upper door device can be simplified, and maintenance work can be simplified and various costs can be reduced.
