Description

The invention relates to an emergency box for use in the elevator, which contains resources for the elevator emergency, the emergency box is provided with an emergency connection device that can connect to a central control center, if the elevator does not work and has stopped, the emergency box only by a PIN number transmitted by the central control center.

Such elevator systems are characterized in that each elevator car is equipped with an emergency call device which is directly or indirectly connected to a central control center. In an emergency, a person in need of assistance transmits a message via the automatic, in particular digital emergency call device to the occupied control center. The control center accepts the emergency call, determines the subscriber and the subscriber-specific data with the aid of its database and informs the service provider in accordance with an alarm plan. The helper drives to the participant. There is a risk that people trapped in the lift urgently need help. In addition, it would be desirable for a signal to be sent to the central control center even when there is no person in the elevator car, when the elevator is not functioning and has stopped.

From the JP 2009 051642 A an emergency cabinet for an elevator car is known in which a plurality of stackable boxes are provided, which are provided for receiving aids for trapped persons. Various closures are proposed for the cabinet, ranging from padlocks to a combination lock, to a digital password entry device. The latter should preferably also be able to be unlocked automatically by an earthquake sensor.

The JP 2008 013339 A discloses an emergency system in which emergency utensils are kept ready in a mechanically locked container. About a ball which rests on a surface with raised border in the container and is connected to a cord with the locking pin, the container is automatically unlocked in case of earthquake by dropping the ball. Alternatively, for maintenance purposes or in the event of power failures without an earthquake, the ball can be brought down via another outward-guided cord. Simultaneously with the opening of the container, a signal is sent to an ambulance service.

Furthermore, from the JP 2009 120291 A an emergency box is known, the closure of which can be opened by a code that is transmitted to a trapped person from a central control center. The contact to this control center is via a QR code, which is attached to a sticker on the box. If this is read out with a smartphone, the person receives a URL to a contact website or a call number of the control center.

In the JP 2008 247483 A also an emergency box with various emergency utensils is described, the lid is locked. The release takes place by entering a code which can be displayed on a display or illuminated by the light color on the corresponding keys of the input device in the dark.

All these prior art devices have in common that they prevent the removal of the stored utensils and materials by a closure mechanism of the lid, but an unfounded access attempt by tinkering with the code input is not prevented.

The invention is therefore an object of the invention to provide an emergency box for use in the elevator, with the people trapped in the elevator while waiting for the helpers can receive timely aids, making sure that access to the tools only is made possible in the event of an emergency. In addition, the central control center is informed about the defect of the elevator, even if the elevator is empty.

This technical problem solves the invention with the features of claim 1.

The emergency box for use in the elevator contains aids for the elevator emergency and is provided with an emergency connection device, which can connect to a central control center, if the elevator does not work and stops, the emergency box only by a PIN number, the of the central control center is to be opened.

The first advantage of the emergency box of the present invention is that, even if the elevator car is empty, a signal is sent to the central control center by the emergency connection device installed on the emergency box if the elevator does not work and stops to allow the elevator so soon as possible can be repaired.

The second advantage is that the emergency box of the present invention is provided with a release mechanism that only activates the PIN entry function when the elevator is not functioning and has stopped. A signal is sent to the central office on the occasion of an elevator emergency by the emergency connection device to automatically activate the PIN entry function by the release mechanism. This avoids decoding the emergency box by tentatively entering any PIN number and removing the materials stored in the emergency box whenever the elevator operates normally.

The emergency connection device is preferably installed on the surface of the housing.

The emergency box according to the invention preferably has several compartments and contains various auxiliary used in an emergency, such as. Glucose, water bottles, cold pack, whistle, handkerchiefs, chewing gum, oxygen mask, urine collection container, flashlights, and / or first aid kits. Bundeswehr one-man rations can also be stored in the emergency box.

Since the situation of being trapped in an elevator car is quite dangerous, especially for people suffering from diseases such. As diabetes, asthma and allergies, it is thus advantageous that the emergency box contains non-prescription drugs for diabetics, allergic persons or for the people suffering from asthma.

Insulin, α-glucosidase inhibitors, sulfonylureas, biguanides, glinides, insulin sensitizers (glitazones), incretin mimetics and dipeptidyl peptidase-4 inhibitors, SGLT-2 inhibitors, and / or amylin analogues can be used as a drug for diabetics in the Emergency box to be stored.

Salbutamol, ipratropium bromide and xanthine can be stored as medicines for people suffering from asthma.

Furthermore, the emergency box can advantageously also with a blood glucose meter with accessories (lancing device, lancets, measuring strips, etc.), sugar solution for diabetics (sugar solution in tubes o. Ä.), Asthma spray, blankets, card games, books and / or a Be equipped mobile phone. For the mobile phone is then preferably an intelligent charging device installed in the box, which regularly ensures a trickle charge of the battery.

The emergency box of the present invention is preferably provided with a magnetic latch or similar latch.

The PIN number set on the emergency box is preferably changed after each use.

The emergency box can be connected to a smoke detector and oxygen masks installed in the elevator car for extended functionality. The smoke detector is preferably mounted on the underside of the elevator car in order to detect smoke rising in the shaft as early as possible. Optionally, even in the entrance area and on the roof more Detectors are installed, which help to detect early from the floors penetrating fumes or fire gases that are heavier than air. The oxygen masks are preferably mounted in the roof of the elevator car and can be released as in airplanes by a flap system. They are available in a number that corresponds to the interpretation for persons of the elevator car. If one of the smoke detectors detects combustion gases, the emergency box releases the oxygen masks and activates the oxygen supply to the masks via a trigger. These can then be activated individually by the users, preferably as in airplanes by pulling on the air hoses.

Furthermore, the emergency box can advantageously control the access to a mounted in the elevator car lockable container for fire extinguishing agents, preferably a fire extinguisher take over. It is constructively and / or electrically connected thereto and unlocks the access to the container in smoke detection by means of the smoke detector. For this type of application, it is useful if in addition to the outside mounted smoke detectors inside the cabin ceiling, a smoke detector is still arranged to detect a fire in the interior of the cabin in good time.

The unlocking of the container takes place, in particular when the container is mounted spaced from the emergency box, by an electrical control, for example, a magnetic lock. If the container is mounted to the emergency box in the manner of a two-door cabinet, the unlocking can also be purely mechanical by retracting locking bolts by means positioned in the emergency box devices. In any case, unlocking takes place independently of a release of the emergency box as soon as a fire has been detected so that the extinguishing agents are immediately available.

Another safety device that can be advantageously used with the emergency box are airbags. For this purpose, the emergency box is connected to airbags installed in the floor and / or lower wall area of the elevator car and released these when passing a contact below the lowest floor. Thus, the airbags can unfold in time before the impact of the elevator car on the mounted below in the shaft catcher or even the shaft floor and protect the passengers on impact. In the case of the airbags arranged in the lower wall region and the airbags located in the floor and opening into the cabin interior, sensors for the standing positions of the passengers preferably ensure that only the airbags open whose opening area does not cover a standing position. In the simplest case, contact switches in the bottom cover are sufficient for this purpose. In this way, the passengers are intercepted by the surrounding airbags during the fall, without being injured by the airbags located at their sites when opening can.

A second variant of the airbags installed in the floor opens down into the shaft and serves to reduce the impact of the elevator car. This second type of airbags can be installed as an alternative or in addition to the other bottom-side airbags.

To ensure the function of the emergency box, it is particularly advantageous with regard to the additional functions, but also for the connection to the control center, in addition to the power supply from the outside also has an emergency battery system that activates and takes over the power supply, if there is one external power failure or the connection of the electrical supply of the elevator car is interrupted.

The emergency box can be retrofitted into an existing elevator or integrated into a newly created elevator.

The emergency box of the present invention is operated by the following method. A signal is sent on the occasion of an elevator emergency by the emergency connection device to the central control center, so that it sends a helper and automatically activates the PIN input function by the release mechanism. A person trapped in the elevator car can contact the central control center through the emergency button installed in the lift wall and thereby obtain the PIN number for the emergency box and open the emergency box.

Further advantages and details of the present invention will become apparent from the described with reference to the drawings and not limiting the invention embodiment.

Fig. 1 FIG. 12 illustrates a view of an emergency box (1) according to the present invention. FIG. Fig. 2 shows their possible installation position in an elevator car. The emergency box is provided with an emergency connection device (not shown) which can connect to a central control station when the elevator does not work and has stopped. A detection of the malfunction can be done for example via a motion sensor and the sensors for the positioning of the elevator car in the floors. If the elevator is not in motion and none of the floor sensors are activated, it is somewhere on the route. The emergency box can only be opened by a PIN number transmitted by the central control center. The PIN number is entered through the keyboard (3). The emergency box is provided with a magnetic lock or similar lock (2).

Fig. 2 shows a representation of an elevator car (6), wherein an emergency box (1) of the present invention is installed on the wall (5) of the elevator car. A signal is sent on the occasion of an elevator emergency by the emergency connection device to the central control center for dispatching a helper and automatically activating the PIN input function by a release mechanism (not shown). A person trapped in the elevator car can contact the central control center through the emergency button (4) installed in the elevator wall and thereby obtain the PIN number for the emergency box and open the emergency box. The emergency box is provided with a magnetic lock or similar lock (2).

It is advantageous if the emergency box of the present invention is provided with a release mechanism, the release mechanism activating the PIN entry function only if the lift fails to function and has stopped. This avoids decoding the emergency box by tentatively entering any PIN number and allowing the materials stored in the emergency box to be arbitrarily removed at any time when the elevator is operating normally.

Even if the elevator car (6) is empty, a signal is sent to the central control center by the emergency connection device (not shown) installed on the emergency box (1) if the elevator does not work and has stopped to allow the elevator as soon as possible can be repaired.
