Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door opening / closing device configured to open and close a plurality of doors at different speeds.
[0002]
[Prior art]
Conventionally, as an elevator car door, for example, there is a double door type as shown in FIG. Two cage doors 101, 102 and 103, 104 are arranged on the left and right sides of the car, respectively, so as to be openable and closable. The car doors 101, 102 and 103, 104 are opened and closed by a door operator provided on the car, and the car doors 101, 102, 103, 104 are accommodated in the door pockets 105 and 106 when fully opened.
[0003]
[Problems to be solved by the invention]
However, in such a conventional elevator car door, when the car doors 101, 102 and 103, 104 are fully opened and stored in the door pockets 105 and 106, there are two left and right doors. As a result, the horizontal area 107 of the cage including them has also increased. For this reason, there is a problem that the volume of the hoistway on which the car travels increases.
[0004]
An object of the present invention is to reduce the horizontal area of a car including a door pocket that houses a car door.

[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. 1 to 6 are views showing an embodiment of a door opening / closing mechanism according to the present invention.
[0007]
In FIG. 1, reference numeral 1 denotes an elevator car side sill. In this sill 1, double-open low-speed doors 2, 3, medium-speed doors 4, 5, and high-speed doors 6, 7 are opened and closed in three on each side. Arranged freely. The doors 2, 3, 4, 5, 6, and 7 are slidably suspended through a hanger on a door rail 8 (actually, only one is shown) provided on the car.
[0008]
As shown in FIG. 2, a pair of first constant sheave 9 and a second constant sheave 10 are disposed on the left and right sides of the car side entrance, and the pair of first constant sheaves 9 (moving panels) is paired with a first pair of first sheaves 9 and 10. A moving sheave 11 and a second moving sheave 12 are provided. A first rope 13 as a linear member is hung on the first and second constant sheaves 9 and 10 and the first and second moving sheaves 11 and 12. That is, one end 13a of the first rope 13 is attached to one end side of the car side entrance, and then the first rope 13 is hung on the first moving sheave 11 and then on the first constant sheave 9, and then the second The other end 13b is attached to the other end side of the car side entrance after being hung on the fixed sheave 10 and then on the second moving sheave 12. A middle speed door 5 is attached to the first rope 13 between the first and second constant sheaves 9 and 10 via a fastening member 14, and the first rope 13 between the second constant sheave 10 and the second moving sheave 12. The middle speed door 4 is attached to the door via a fastening member 15.
[0009]
As shown in FIG. 3, a pair of third and fourth constant sheaves 16 and 17 and fifth and sixth constant sheaves 18 and 19 are arranged on the left and right sides of the car side doorway, respectively, and the low speed door 2 A pair of third moving sheave 20 and fourth moving sheave 21 is provided. A second rope 22 as a linear member is hung on the third, fourth, fifth and sixth constant sheaves 16, 17, 18, 19 and the third and fourth moving sheaves 20, 21. That is, the second rope 22 whose one end 22a is fixed to the low speed door 2 is hung on the fourth constant sheave 17, then hung on the third moving sheave 20, and then hung on the third constant sheave 16. Then, after being hooked on the fifth constant sheave 18 and then on the fourth moving sheave 21 and then on the sixth constant sheave 19, the other end 22 b is fixed to the low speed door 2. A high speed door 7 is attached to the second rope 22 between the third and fifth constant sheaves 16 and 18 via a fastening member 23, and the second rope 22 between the fifth constant sheave 18 and the fourth moving sheave 21 is attached to the second rope 22. Also, the high speed door 6 is attached via the fastening member 24. The low speed door 3 is attached to the second rope 22 between the fourth moving sheave 21 and the sixth constant sheave 19 via a fastening member 25.
[0010]
Here, when the low-speed door 2 in the doors 2, 3, 4, 5, 6 and 7 in the fully closed state is opened to the left in FIG. The speed doors 4 and 5 are opened and operated via the first rope 13 at a speed twice that of the low speed door 2. Further, as shown in FIG. 3, the high speed doors 6 and 7 are simultaneously opened through the second rope 22 at a speed three times that of the low speed door 2, and the low speed door 3 is also at the same speed as the low speed door 2. Now it is opened. As shown in FIG. 4, when the low-speed doors 2 and 3 are opened, the medium-speed doors 4 and 5 are simultaneously opened at the double speed, and the high-speed doors 6 and 7 are simultaneously opened at the triple speed. Next, as shown in FIG. 5, when the low speed doors 2 and 3 are in the fully open position, the medium speed doors 4 and 5 and the high speed doors 6 and 7 are also in the fully open position.
[0011]
When the low-speed doors 2 and 3, the medium-speed doors 4 and 5 and the high-speed doors 6 and 7 are fully opened, they are stored in the door pockets 26 and 27, as shown in FIG. Since it is a sheet, the door pockets 26 and 27 can be made small. For this reason, the horizontal area 28 of the car including the door pockets 26 and 27 can be reduced.
[0012]
When the low-speed door 2 is closed by the driving means among the doors 2, 3, 4, 5, 6 and 7 in the fully open state, the medium-speed doors 4 and 5 are connected to the 2 of the low-speed door 2 via the first rope 13. The high-speed doors 6 and 7 are closed at a triple speed through the second rope 22 and simultaneously closed at a double speed.
[0013]
By the way, it is conceivable to open and close a large number of doors 2, 3, 4, 5, 6, and 7 not by the roping mechanism as described above but by a link mechanism. In this case, the low-speed doors 2 and 3 and the medium-speed door 4 In order to open and close the high-speed doors 6 and 7 at a speed of 1: 2: 3, it is necessary to improve the manufacturing accuracy and mounting accuracy of the link mechanism. However, with the roping mechanism, a large number of doors 2, 3, 4, 5, 6, and 7 are reliably interlocked at a speed of 1: 2: 3 even if the manufacturing accuracy and the mounting accuracy are not so high.
[0014]
In the above embodiment, the present invention is applied to the car side, but may be applied to the landing side.
[0015]
Next, as shown in FIG. 7, in addition to the low speed door 31 provided with the first moving sheave 11 and the second moving sheave 12, the first rope 13 between the second constant sheave 10 and the second moving sheave 12 When the medium speed door 33 is attached via the fastening member 32 and the high speed door 35 is attached to the second rope 22 between the fifth constant sheave 18 and the fourth moving sheave 21 via the fastening member 34, It becomes a door opening and closing mechanism.
[0016]
In the above embodiment, the rope is used as the linear member, but the present invention is not limited to this, and a chain, a timing belt, or the like may be used.
[0017]
【The invention's effect】
As described above, according to the present invention, a pair of low-speed doors are attached to the moving panel and the second linear member between the second moving sheave and the sixth constant sheave, respectively, and the first constant sheave and the second constant sheave. A pair of medium-speed doors are respectively attached to the first linear member between the second constant sheave and the first linear member between the first moving sheave and the second linear shape between the third constant sheave and the fifth constant sheave. Since a pair of high-speed doors attached to the member and the second linear member between the fifth constant sheave and the third dynamic sheave are attached, a pair of low-speed doors, a pair of medium-speed doors, and a pair of high-speed doors are stored. Can be made smaller. As a result, the horizontal area of the car including the door pocket can be reduced, and the hoistway can be made compact.
