Abstract

PURPOSE:To provide a two-story type elevator device which is designed to reduce the overall height of a car according to the lower height of an entrance when a lower entrance is different from an upper entrance. CONSTITUTION:A car 1 is provided at a lower part with a lower car room 3 and at an upper part with an upper car room 5. Further, the car is provided with a high door device 8 to open and close the entrance 6, being higher, of the entrances of the lower and upper car rooms 3 and 5 and a low door device 7 constituted in a manner to be lower than the high door device 8 to open and close a lower entrance 4. The positions of the engaging bodes 14 of the low and high door devices 7 and 8 engaged with an engaging mechanism at an elevator hall are arranged in the same position from respective mating entrance floor surfaces. In addition to above, the overall height of the car 1 is reduced by a difference in height between the high and low entrances. This constitution causes reduction of the weight of a car and shortening of the overall height of an elevator shaft, resulting in saving of a cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-deck elevator, in which a lower car room and an upper car room are provided with entrances of different heights, that is, a second-floor elevator system.

[0002]

2. Description of the Related Art FIG. 5 and FIG.
FIG. 5 is a view showing a conventional second-floor type elevator device similar to the second-floor type elevator device shown in Japanese Patent No. 0740.
6 is a front view of the elevator car, and FIG. 6 is a rear view of the landing where the car of FIG. 5 stops. In the figure, (1) is the hoistway
(2) elevator car, (3) car with entrance (4)
Lower car located near the bottom of (1), lower car room (5)
An upper car room (7) with an entrance (6) of a height higher than that of the entrance (4) of (3) and a car room (3) above the car (1) Lower door device installed in 1) to open and close the entrance (4) of the lower car room (3), (8) is installed in the car (1) and opens and closes the entrance (6) of the upper car room (5) The upper door device.

The lower door device (7) and the upper door device (8) are well-known door devices, and are a drive motor (9), a speed reducer (10), a door rail (11) and a door hanger (respectively). 12), a car door (13), an engagement body (14), a link (15) for opening and closing the car door (13), a safety edge (16) and a car sill (17).

Reference numeral (18) is a hall provided in the hoistway (2) and facing the car (1) when stopped, and a door device (20) for opening and closing the hall entrance (19) is provided. The door device (20) is a well-known landing door device, and the hanger case (21),
Door rail (22), door hanger (23), interlock hook (24), interlock latch (25), interlocking rope
(26), hall door (27), engagement mechanism (28) and hall threshold (29)
It is composed by.

The conventional second-floor type elevator device is constructed as described above, and, for example, the car (1) moves up and down to move to the upper car room (5).
When the vehicle arrives at the required landing (18), the control device (not shown)
Operates and issues a door open command. This allows the drive motor
A roller that rolls on a door rail (11) fixed to the frame of the door device via a link (15) that is biased by (9) to open and close the reduction gear (10) and the car door (13). The cage door (13) suspended on the door hanger (12) having the opening starts to open.
At this time, the engagement body (14) of the car side door device is
8) Engagement on the landing side fixed to the door (27) of the landing suspended on the door hanger (23) that has rollers for rolling the rails (22) of the door fixed to the hanger case (21) Engage mechanism (28).

[0006] Then, by the door opening operation of the car door (13), the interlock hook (24) and the interlock latch (25).
The doors (13) of the car and the doors (27) of the landing are opened electrically by releasing the engagement of the doors. The same door opening / closing operation as in the case of the upper car room (5) is performed in the lower car room (3). Also, the lower door device (7) and the upper door device
(8) is an independent door device for a specific hall (18)
It does not open and close electrically by engaging with (20), and it opens and closes by engaging with the door device (20) at any landing (18) where the car (1) is stopped and is facing. It is like this.

[0007]

In the conventional second-floor type elevator device as described above, the entrance (4) of the lower cab (3)
When the height of the entrance and exit (6) of the upper car room (5) is different from that of the upper car room (5), the lower door device (7) and the upper door device (8) are the same, and the height direction configuration of these is used. The height direction configuration of the lower entrance / exit is matched to the height entrance / exit, so that the positions of the engagement bodies (14) in the height direction from the entrance / exit floor surface are matched. Therefore, the total height of the car (1) is the same as when the entrance (4) of the lower car room (3) and the entrance (6) of the upper car room (5) are in the same height. Therefore, the basket
There is a problem that the weight of (1) is increased and the hoistway including the pit and the top dimension (2) is increased in height, resulting in an increase in cost.

When the design is changed to the link (15) for opening and closing the car door (13) of the car door device of the lower entrance and exit, depending on the entrance and exit height dimension and the entrance and exit width dimension, the link (15 The configuration of 15) may become impossible. In addition,
The car room with a low entrance and exit provided in the car (1) is often planned for cargo only, and the loading capacity is smaller than that of a passenger car room with a high entrance and exit in the same floor area.

The present invention has been made to solve such a problem, and when the entrances of the lower car room and the entrances of the upper car room are different in height, the total height of the car is set to the height of the entrance and exit. It is an object of the present invention to obtain a second-floor type elevator device that can be shortened according to the difference in
