Abstract

PURPOSE: To flow no air flow into a ventilating hole at a high speed by cover the ventilating hole with a porous member. CONSTITUTION: A sponge 15 is positioned at a square space formed by a retaining plate 14 and an auxiliary plate 2a. A lower end side of the retaining plate 14 is notched to a square and an entrance/exit of an air from the notched portion 14a can be carried out. When an elevator is traveled at a high speed, a high speed air stream at the outside of a cage room is about to flow into the cage 1 from a ventilating hole 10. However, since the ventilating hole 10 is covered with the sponge 15, the air flows into the cage 1 so as to slowly penetrate. Therefore, even if the air enters the ventilating hole 10, a swish is not generated and an uncomfortable feeling is not imparted to a passenger in the cage.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car room of an elevator in which ventilation holes formed in a car panel are soundproofed.

[0002]

2. Description of the Related Art In an elevator car room, side panels, rear panels, return panels, etc. are erected on the floor surface.
A ceiling is provided above these, and a kick plate is provided between the floor and the side panel and the rear panel.

The ceiling is provided with a blower for sending air into the car room, and the air sent into the car room is exhausted from ventilation holes formed in the lower part of the return panel, the side panel and the rear panel.

[0004]

By the way, recently, some elevators have been speeded up, and in such an elevator, an air flow flows at a high speed outside the cab that travels at a high speed. . Then, the high-speed airflow enters the car room through the narrow ventilation hole. Here, since the airflow that flows into the narrow ventilation hole is at a high speed, there is a problem that a wind noise is generated when the airflows, which makes passengers uncomfortable.

An object of the present invention is to provide an elevator cab in which an air flow is prevented from flowing into a ventilation hole at a high speed.

[0006]

In order to achieve such an object, the present invention has ventilation holes formed in the lower part of a return panel, a side panel and a rear panel which are erected on the floor. In the elevator cab, the ventilation holes are covered with a porous member.

[0007]

When the elevator is operated at a high speed, a high-speed air flow will flow outside the cab. This air flow tries to flow in from the ventilation hole, but since this ventilation hole is covered with the porous member, it cannot flow in as it is in the high-speed flow, and it permeates into it.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of an elevator cab according to the present invention.

In FIG. 2, reference numeral 1 is a floor surface of a cab, and a pair of side panels 2 are provided at both left and right ends of the floor surface 1.
3, a return panel (not shown) and a rear panel 4 are provided upright at the front and rear ends. Side panels 2 and 3, rear panel 4, ceiling 5 above the return panel
The ceiling 5 is provided with a blower 6 for blowing outside air into the car room, and fluorescent lamp type lighting devices 7 and 8 are provided on both sides thereof. Kick plates 9 and 16 are provided between the floor surface 1 and the side panels 2 and 3, and a kick plate 17 is also provided between the floor surface 1 and the rear panel 4.

The kick plate 9 has a substantially U-shaped cross section as shown in FIG. 1. The lower end of the plate 9 is fixed to the floor surface 1, and the upper end of the kick plate 9 is attached to the side panel 2 via an auxiliary plate 2a. It is fixed to the lower end of 2. A plurality of ventilation holes 10 are formed in the auxiliary plate 2a.

The air blown into the car room by the blower 6 is
The air is exhausted from the ventilation hole 10 to the outside. A sponge 15 having a substantially square cross section is placed on the ventilation hole 10 so as to cover it. Auxiliary plate 2a on the side panel 2
A supporting piece 11 having a substantially L-shaped cross section is fixed slightly above,
A pop nut 12 is attached to the support piece 11. By screwing the screw 13 into the pop nut 12, the supporting plate 11 has a holding plate 14 having a substantially L-shaped cross section.
Is fixed.

A square space is formed by the holding plate 14 and the auxiliary plate 2a, and the sponge 15 is located in this space. As shown in FIG. 3, the holding plate 14 has a rectangular cutout on the lower end side.
Air can flow in and out through the notched portion 14a. The lower part of the side panel 2 also includes the auxiliary plate 2a and the kick plate 9.

When the elevator is operated at a high speed, a high-speed airflow will flow outside the cab. This air flow tries to flow from the ventilation hole 10, but this ventilation hole 1
Since 0 is covered with the sponge 15, it cannot flow in as it is in a high-speed flow, and it flows in so that it permeates slowly.

Therefore, even if air enters through the ventilation hole 10, no wind noise is generated. Since the ventilation hole 10 is covered with the sponge 15, the air in the car room can be discharged from the ventilation hole 10 to the outside through the sponge 15. The other side panels 3, the rear panel 4, and the lower part of the return panel also have the same structure as described above.

By the way, a pair of guide rails are provided upright on both sides of the cab, and guide rollers attached to the cab are slidably engaged with the guide rails. As the cab moves at high speed, the guide rollers also move at high speed on the guide rails. When the guide roller travels on the guide rail at a high speed, the abnormal noise generated during this travel also becomes large. This loud noise will be heard by passengers in the cabin through the ventilation hole 10, but since the ventilation hole 10 is covered by the sponge 15,
The abnormal noise is significantly reduced when transmitted to the room.

[0016]

As described above, according to the present invention,
Since the ventilation hole is covered with the porous member, the air flow flowing outside the cab is gradually permeated into the ventilation hole. Therefore, even if air enters the ventilation hole, no wind noise is generated, and passengers in the cab are not uncomfortable. Also, abnormal noise generated when the guide roller travels on the guide rail is significantly reduced when it is transmitted to the car interior.
