JPH0218275A - Escape device for elevator - Google Patents

Abstract

PURPOSE:To enable refuge to be taken without waiting for a rescue by a serviceman by providing an emergency door in a side plate of a cage chamber and a staircase in the internal wall of a lift path corresponding to this emergency door, in a small elevator set up in a small-to-medium-sized building and/or an individual house. CONSTITUTION:An opening part 9 is provided in a side plate 8 of a cage 1, and an emergency door 10, for closing this opening part 9, is provided. In the normal time, the opening part 6 is left as closed by the emergency door 10. The cage 1 mounts an illumination device to the outside in the opening part 9 and an illumination device 12 even to the bottom surface of the cage 1. While a staircase 14 by a steel frame is provided in a lift path 2 over the total length of its internal wall mutually facing to the opening part 9. An emergency exit 15 is set up in the bottom part of the lift path, and this emergency exit 15 is left as connected to the outside of the lift path. Accordingly, when an elevator is stopped by power interruption or the like, if a passenger in the cage removes the emergency door 10, the opening part 9 appears, and the passenger steps down along the staircase 14 to the bottom part of the lift path, being able to escape from the emergency exit 15.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an escape device for elevator passengers.

(Prior Art) A conventional elevator will be explained based on FIG.

The elevator includes a car 1 for passengers to ride, a hoistway 2 for the car 1 to run up and down, a hoist 3 and a hanging row 14 for moving the car 1, a counterweight 5, a landing entrance 6 provided in the hoistway, etc. It consists of

By the way, when an elevator car is stopped due to a power outage while carrying passengers, the passengers are prevented from escaping from inside the car by using their own blades.

This is because in the hoistway of a normal building, if a general passenger carelessly leaves the car, there is a danger of falling into the hoistway or being caught by machinery surrounding the car.

Therefore, when a passenger is trapped in a car due to an accident, the passenger generally escapes from the car by the following means.

First, the passenger in the car reports the accident to the building manager using an intercom or other means. Upon receiving this information, the building manager contacts a specialized service company, which dispatches a service worker, who rescues the passenger through the rescue exit provided above the elevator car.

That is, as shown in FIG. 3, when the elevator car 1 is stopped halfway between the floors, the service staff uses a special unlock key to unlock the hall entrance 6. Climb on top and open the rescue lower on the car to rescue the passengers inside the car.

(Problem to be Solved by the Invention) However, as elevators become more widespread, there are many cases where this method alone cannot be used for the first reason.

In other words, we are now in an era where elevators are not only used in large buildings but also in small and medium-sized buildings and private homes, and the number of elevators that service personnel are responsible for is increasing, so service personnel must be on standby at all times to prevent accidents. This has become a difficult problem.

In particular, in the event of an earthquake or large-scale power outage, many elevators stop at the same time, making it difficult to rescue each elevator in a short period of time.

In addition, in private residences, elevators are only used by family members, so if a breakdown or power outage occurs when family members other than the user are not home, the elevator will be in trouble for a long time without being able to communicate with outside parties. There is a high possibility.

The present invention solves these problems by providing an escape device for small elevators used in small and medium-sized buildings and private residences that allows users to safely escape from a canned state using their own blades9. [Structure of the Invention] (Means for Solving the Problems) An opening and an emergency door to close the opening are provided on the side plate of the elevator car, and a ladder-like staircase is provided on the inner wall of the hoistway corresponding to the opening.

(Function) When an elevator stops running due to an earthquake, etc., passengers remove the emergency door on the side panel of the car, escape through the opening, descend to the bottom of the hoistway via the ladder-like stairs, and then
Exit the hoistway through the emergency exit.

(Example) An example of the present invention will be described based on FIGS. 1 and 2.

The basic structure of the car 1, hoisting R3, hanging row 14, counterweight 5, landing entrance 6, etc. is the same as that of the conventional example.

An opening 9 is provided in the side plate 8 of the car 1, and an emergency door 10 is provided to close the opening 9. Normally, the opening 9 is closed by the emergency door 10.

A lighting device 11 is attached to the outside of the cage in the opening, and a lighting device 12 is also attached to the bottom surface of the cage.

The switch 13 of the lighting device is installed inside the car.

On the other hand, a ladder rung 14 made of a steel frame is provided over the entire length of the inner wall of the hoistway facing the opening 9. An emergency exit 15 is installed at the bottom of the hoistway, and this emergency exit 15 is connected to the outside of the hoistway.

With the above configuration, when the elevator stops due to a power outage, etc., when a passenger in the car removes the emergency door 10, the opening 9 appears.
The user descends to the bottom of the hoistway via the stairs 14 formed in the shape of a ladder made of steel frames, and escapes through the emergency exit 15. Furthermore, when descending along the hoistway 2, if the lighting 11 installed in the opening 9 in the car and the lighting 12 installed at the bottom of the car are turned on in advance, the inside of the hoistway will be bright and it will be possible to evacuate safely. can.

[Effects of the Invention] As described above, according to the present invention, in small elevators installed in small and medium-sized buildings or private residences where the hoistway has a relatively short travel distance, it is possible to safely operate a small elevator without waiting for service personnel to rescue the user. can do.

Particularly in the event of a large-scale disaster such as an earthquake, many elevators stop working at the same time, which takes time for rescue operations, but with this device, escape is possible immediately and can be used with peace of mind.

In addition, when an elevator is installed in a private home, there are few people who use it, so even if the elevator stops and you are trapped inside, people around you may not notice.
To prevent this, conventionally the only method was to install a telephone in the elevator and request a service company, but according to the present invention, it becomes possible to use the elevator without relying on others.
