Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for reducing vibration and noise generated when a car of a high speed elevator is traveling.

[0002]

2. Description of the Related Art As a conventional vibration and noise prevention measure for a high speed elevator, there is one described in Japanese Patent Publication No. 47-46374. This conventional example will be described with reference to FIG. 3 which is a schematic vertical sectional view of a hoistway and FIG. 4 which is a schematic horizontal sectional view of a main portion thereof.

In the figure, 1 is a wall of a hoistway, 2 is a main rope connecting a car 3 and a counterweight 4 at both ends, and 5
Is a compensating rope, 6 is a compensating sheave, 7 is a machine room 8
The sheave of the hoist installed at No. 9 and the deflecting sheave 9 are.
10 is a sill of the car, 11 is a groove of the sill 10, 12 is an entrance pillar standing on both sides of the entrance / exit 13, 14 is a car door for opening / closing the entrance / exit 13, and 15 a and 15 b are inserted into the sill groove 11. A guide tool fixed to the lower end of the door 14 for guiding the opening and closing of the door 14, and 16 is a car floor. 20 is a sill of the hall 21, 22 is a sill groove, 23 is a vertical frame of a three-way entrance / exit, 24 is a landing door that opens and closes an entrance / exit 25 of the hall, 26
Reference numerals a and 26b are guides for the door 24.

In a high speed elevator, as shown in FIG.
For example, when the car 3 descends, an air flow occurs from the bottom to the top between the car 3 and the hoistway wall 1. In particular, the flow q1 of the car 3 on the landing side greatly varies depending on the position of the car 3. That is, as shown in FIG. 3, the car sill 10 is the landing sill 2
The flow q1 is relatively smooth when not facing 0, but when the car sill 10 reaches a position facing the landing sill 20, the flow q1 is interrupted by the sills 10 and 20 and suddenly decreases. Therefore, the flow q1 greatly changes as the car 3 travels, which causes the car door 14 and the landing door 24 to vibrate, which causes noise. Also, when the car 3 rises, vibration and noise are similarly generated only by reversing the flow direction.

Therefore, in order to reduce the fluctuation of the flow q1, as shown by the chain double-dashed line in FIG.
Further, by providing the notch portion 17 which is formed by notching a part of the car floor 16, the fluctuation of the flow q1 is reduced, and the vibration and noise are reduced.

[0006]

In the above-mentioned conventional apparatus, since the sill 10 and the car floor 16 in the door pocket portion are notched, when the door 14 is opened, the guide tool 15b on the door open end side is formed.
Is in a free state, and the opening / closing operation of the door 14 becomes unstable.

[0007]

According to the present invention, in addition to a structure in which a sill of a door pocket portion and a car floor are cut out, a second sill is provided on the side opposite to the landing side of the sill of the cutout portion, and the car door A guide tool guided by the sill is provided on the door closed end side, and a guide tool guided by the second sill is provided on the door open end side of the door.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to the drawings. 1 is a schematic cross-sectional view of a main part, FIG. 2 is a perspective view of the main part, and the same reference numerals as those in FIG. 4 denote the same parts. In the figure, 30 is a notch part that is formed by cutting out a part of the sill 10 and the car floor 16, 31 is a second sill installed on the side opposite to the sill 10 than the sill 10, 32 is a groove thereof, and 33 is a car door 14. It is fixed to the door open end side, and when the door is closed, the door 14 and the entrance pillar 1
Reference numeral 34 is a cover that closes the gap between the two, and is a guide tool that is fixed to the lower end of the cover 33 so as to be inserted into the sill groove 32 and guides opening and closing of the door 14.

Since the present embodiment has the above-mentioned structure, the door closed end is guided by the guide member 15 regardless of whether the door 14 is opened or closed.
The door 14 is guided to the groove 11 of the sill 10 by a, and the door open end is guided to the groove 32 of the second sill 31 by the guide 34 through the cover 33, so that the door 14 can be opened and closed smoothly. Further, since the cover 33 closes the space between the door 14 and the entrance post 12 and the end of the sill groove 11 when the door is closed, noise from the hoistway can enter the car while the car 3 is running. There is an effect to prevent.

In the above embodiment, the sill 10 on the side of the car 3 is used.
Although the car floor 16 is cut away, the hall side may have the same configuration. That is, similarly to the above-described embodiment, the hall sill 20 and the notch portion 40 that is formed by notching a part of the building.
If the second sill is installed and the cover and the guide are arranged at the door open end of the hall door 24, the distance between the car 3 and the hall 21 can be further increased, and vibration and noise can be further reduced. be able to.

[0011]

As described above, according to the present invention,
In addition to the effect of reducing the fluctuation of the air flow during elevator travel, the door opening / closing operation can be performed smoothly.
