DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary elevator, and more particularly to a rotary elevator for getting on and off a trolley or a wheelchair.
The present invention relates to a rotary elevator capable of smoothly performing the getting on / off operation.

[0002]

2. Description of the Related Art In general, an elevator is provided with a box-shaped ladder, and when a user who gets on the ladder designates a destination floor, the ladder rises and descends in a hoistway, and a user is moved. Carry to the destination floor. In such an elevator, a single door is usually provided in a cab, and a user gets on and off through this door.

[0003] Japanese Patent Publication No. 57-22874 discloses an elevator in which a rotatable turntable is provided on a lift and the direction of luggage on the turntable can be reversed.

[0004]

However, if only one door is provided as in the above-mentioned conventional elevator, it is very inconvenient when getting on and off with a bogie or a wheelchair.
That is, if there is only one door in the basket,
It is necessary to reverse the direction each time when getting off after getting on with a trolley or wheelchair, especially when the ladder is small or the inside of the ladder is crowded, it becomes difficult to reverse the The disadvantage is that it takes time to get off.

The elevator described in Japanese Patent Publication No. 57-22874 is installed in factories, warehouses, etc., and transports luggage, not elevators for transporting people. There are no elevators for transporting people that have the function of reversing the direction of a person who has entered the cage.

[0006] It is an object of the present invention to provide an elevator that can easily get off from a basket even when it is boarded by a bogie or a wheelchair, by providing a function of reversing the direction of a person getting into the basket. is there.

[0007]

In order to achieve the above object, according to the present invention, there is provided a ladder provided with two doors at diagonal positions on a side surface and rotatable around a central axis. ,
Lifting drive means for raising and lowering the basket along the hoistway,
Rotation driving means for rotating the riding cage around a central axis,
And a rotary elevator.

[0008] In the case of using the rotary elevator having the above configuration, the user gets into the car from one of the two doors, and operates the operation panel in the car, for example, so that the rotary drive means is driven. Drive to rotate the basket 180 degrees. Then, when the basket reaches the destination floor by the lifting drive means, the user can get off from the other door by moving forward.

According to a second aspect of the present invention, there is provided a riding cage provided with a rotatable rotary table on a floor portion, a lifting drive means for lifting and lowering the riding basket along a hoistway, And a rotary drive means for rotating the rotary elevator around.

In the first aspect, the entire basket is rotated. In the second aspect, only the rotary table on the floor of the basket is rotated without rotating the basket. The user gets into the basket and operates the operation panel,
The rotation driving means is driven to rotate the rotary table by 180 degrees. As a result, the user turns around in the basket and can get out of the basket through the same door as when he / she got in.

[0011] The invention described in claim 3 is the invention according to claim 1 or 2.
In the above aspect, the riding cage is a rotary elevator, wherein a side portion has a cylindrical surface.

If the side of the basket has a cylindrical surface, it is advantageous to make the basket rotatable.

The invention described in claim 4 is the first or second invention.
, The rotary drive means is provided in the basket, and is a rotary elevator.
According to a fifth aspect of the present invention, there is provided the rotary elevator according to the first or second aspect, wherein the rotary drive unit is provided in the lift drive unit.

The rotary driving means can be provided in a cab (for example, an upper portion or a lower portion of the cab) as in claim 4, and in the case of a hydraulic jack type elevator,
It is also possible to provide the lifting drive means as in claim 5.

The wire rope 8 is wound around a sheave 10 provided above the hoistway 2, and a balance weight 11 is attached to the other end of the wire rope 8.
Is attached. The rotation output of the motor 12 is transmitted to the sheave 10 via the speed reducer 13.

Next, the cage main body 4 will be described in detail. 3 and 4 show a detailed structure of the basket body 4, FIG. 3 is a sectional view taken along line AA of FIG. 4, and FIG.
It is sectional drawing along the BB line of FIG. As shown in the figure, the cage main body 4 has a cylindrical shape, and a side portion thereof has a cylindrical surface. Doors 15A and 15B and door 16 are located at diagonal positions of the cylindrical surface.
A and 16B are provided, and the doors 15A and 15B reciprocate in the direction of arrow C, and the doors 16A and 16B reciprocate in the direction of arrow D. 1
Reference numerals 7 and 18 denote door storage units.
A and 15B, and doors 16A and 16B are stored in the door storage unit 18, respectively.

An operation panel 19 is mounted inside the basket body 4. The operation panel 19 includes a destination floor instruction button for inputting a destination floor of a user and a door opening / closing button for opening / closing a door. Is provided. Also,
The operation panel 19 is also provided with a basket rotation button for rotating the basket main body 4.

In the rotary elevator having the above configuration, when the user gets on the trolley body 4 from the doors 15A and 15B with a trolley or a wheelchair, the user operates the destination floor support button and the door open / close button on the operation panel 19. If the basket rotation button is operated at the same time as the operation, the motor 5 is driven and the basket main body 4 is rotated, for example, 180 degrees clockwise in FIG.
Thus, the direction of the user is also rotated by 180 degrees, and the user can get down from the doors 16A and 16B simply by moving forward. Of course, when the user is not in a bogie or a wheelchair, but gets in a state in which it can be inverted inside the basket main body 4, it is not necessary to rotate the basket main body 4, and when the user gets in from the doors 15A and 15B, the doors 15A and 15B are kept as they are. You can get off from 15B.

(Embodiment 2) FIGS. 5 and 6 show a detailed structure of a ladder body according to Embodiment 2 of the present invention. FIG. 5 is a sectional view taken along line EE in FIG. FIG. 6 shows FIG.
