Description

Elevator car personnel evacuating device

Technical Field

The utility model relates to a be suitable for and evacuate personnel to elevator car personnel evacuating device in rescue elevator car with personnel from elevator car stranded.

Background

The elevator system comprises at least one elevator car, which is usually arranged in an elevator shaft vertically movably along guide rails for transporting people or goods between two floors. Such elevator systems are maintained continuously during their operation in order to be able to ensure the transported persons or to ensure the safety of the elevator system. However, the operation of the elevator installation can be interrupted by external influences or faulty components of the elevator installation. For example, a power failure, a lightning strike or an interrupted safety circuit of an elevator system can cause an elevator car and people located therein to be trapped between two floors. The people stuck in the elevator car must then be evacuated from the elevator car.

JP2005-154025a shows an evacuation device for evacuating people in the case of two elevator cars which are movably arranged adjacent to one another in an elevator shaft during normal operation. The second elevator car is positioned beside the first elevator car if a first of the two elevator cars is stuck in the hoistway. The evacuation channels of the two elevator cars facing each other can be opened. The evacuation channels can be connected by a people aisle, wherein the people aisle can be fastened to the respective lower boundary of the evacuation channels. In order to evacuate the first elevator car, the person to be evacuated passes through the people corridor in order to reach the second elevator car, which can still be moved.

Usually, in order to fix the guide rails of two elevator cars at regular intervals between the travel paths of the two elevator cars, a horizontally extending fixing carrier is arranged. Disadvantageously, such a fixed carrier may hinder, when evacuating the first elevator car: the persons to be evacuated can enter the second elevator car unhindered while passing through the walkway. This is the case when the fixed carrier is located directly in front of the evacuation channel.

Furthermore, in the prior art, since the walkway is heavy, dedicated hoisting and moving equipment is required to move the walkway from one elevator car (e.g. a movable rescue elevator car) to another elevator car (e.g. an immovable trapped elevator car), which causes great difficulties in the installation and use of the walkway.

According to the utility model discloses a general technical concept provides an elevator car personnel evacuating device, include: an evacuation channel, which can be built on an elevator car; and a pedestrian aisle. The elevator car people evacuation device further comprises a sliding rail for connecting between the evacuation channels of the two elevator cars, on which the people passage can be slidably supported so as to be movable between the two elevator cars by means of the sliding rail.

Fig. 1 shows an elevator car 5 of an elevator system blocked in an elevator shaft 2. The elevator shaft 2 adjoins two floors 10.0, 10.1 arranged directly above one another. Each floor 10.0, 10.1 has a shaft door 11.0, 11.1. During normal operation of the elevator car 5 in the unlocked state, elevator passengers can enter or leave the elevator car 5 via the car doors 6 of the elevator car 5 and the shaft doors 11.0, 11.1 on which the elevator car 5 rests when it stops at a floor.

The blocked elevator car 5 according to fig. 1 is disposed between two floors 10.0, 10.1 disposed directly above one another. This means that the interior of the elevator car 5 cannot be reached from one of the floors 10.0, 10.1 by means of one of the shaft doors 11.0, 11.1. With the same effect, the elevator car 5 can instead also be arranged on one of the shaft doors 11.0, 11.1, the car door 6 or the respective shaft door 11.0, 11.1 on which the elevator car 5 is arranged being blocked in the closed position. Accordingly, a person located in the elevator car 5 cannot leave the elevator car 5 by means of the car door 6 or by means of one of the shaft doors 11.0, 11.1.

In order to be able to evacuate passengers in the elevator car 5, the elevator car 5 has evacuation channels. The exit from the elevator shaft 2 can be reached, for example, via an evacuation channel of the elevator car 5.

The evacuation channel is designed as an evacuation door 20. Such an evacuation door 20 is arranged in one of the side walls 8 of the elevator car 5 and can be opened, for example, only from the outside, so that a service technician can safely evacuate people from the blocked elevator car.

Alternatively or additionally to this, the elevator car 5 can have an evacuation channel arranged on the car roof 7 of the elevator car 5. Such an evacuation channel arranged on the car top 7 can be reached through a roof panel 30 located in the car top 7 by means of a ladder which can be arranged temporarily in the elevator car 5 by way of example.

Fig. 2 shows an evacuation channel designed as an evacuation door 20, which is arranged in one of the side walls 8 of the elevator car 5. Fig. 3 shows the components of the device for evacuating people, which are designed as an integral component of a balustrade 15 arranged on the ceiling 7.

In the evacuation channels shown in fig. 2 and 3, the components of the device for evacuating people are arranged. The lower end of the evacuation channel is defined by the foot elements 46 of the device. The footboard elements 46 can be used for stepping on stairs, i.e. for stepping on feet, or for suspending or fixing a bridge, i.e. an evacuation bridge, not shown in fig. 2 and 3. The device comprises at least one crosspiece 47.0, 48.0, 49.0, wherein the crosspiece 47.0, 48.0, 49.0 can be fixed above the footboard element 46. The uppermost of the elements which are fixed in the evacuation channel during evacuation, including at least one fixed crosspiece 47.0, 48.0, 49.0 and the footboard element 46, serves for fixing the bridge during evacuation. Preferably, these elements lying directly above one another have a vertical distance of between 20 and 30cm, preferably 26 cm.

In order to be able to fix the at least one crosspiece 47.0, 48.0, 49.0 in the evacuation channel, a vertical beam 45 may be provided on the side of the door opening. The vertical beams 45 have fixing areas 47, 48, 49 corresponding to the respective crosspieces 47.0, 48.0, 49.0 for fixing the crosspiece/s 47.0, 48.0, 49.0 in the evacuation channel. Preferably, a vertical beam 45 vertically aligned with the footboard elements 46 can be fixed on the side wall 8 with evacuation channel or on the protective railing 15 of the elevator car 5 in such a way that a part of the door frame or of the balustrade 15 for the evacuation channel is formed by the vertical beam 45.

The second vertical beam 45' may be disposed on the other side of the evacuation channel with respect to the first vertical beam 45, and may be configured like the first vertical beam 45. Correspondingly, the second vertical beam 45 ' has, for fixing the crosspiece/s 47.0, 48.0, 49.0, fixing areas 47 ', 48 ', 49 ' corresponding to the respective crosspiece 47.0, 48.0, 49.0, wherein the fixing areas 47 ', 48 ', 49 ' are preferably arranged such that the crosspiece/s 47.0, 48.0, 49.0 are horizontally aligned in the evacuation channel,

in addition, the safety barrier 52 can be arranged inside the evacuation channel in such a way that the evacuation channel is blocked despite the opening of the evacuation door or railing 15. The safety barrier 52 shown in fig. 2 and 3 is designed in the form of a rod. The blocking safety barrier 52 is fixed, for example, on at least one vertical beam 45, 45 'of the device and/or above all fixing regions 47, 48, 49, 47', 48 ', 49' that can correspond to the crosspieces 47.0, 48.0, 49.0. The safety barrier 52 comprises a safety contact 53, the safety contact 53 preferably being closed in a position of the safety barrier 52 blocking the evacuation channel. Removal of the safety barrier 52 results in switching of the safety contacts 53 and therewith unlocking of the evacuation channel. The safety contact 53 can, for example, be coupled into a safety circuit of the elevator system, wherein an opened safety circuit prevents the travel of the elevator car corresponding to the safety circuit.

The footboard elements 46 shown in fig. 2 are preferably arranged above the plane of the car floor 9 of the elevator car 5, so that the car floor 9 forms the bottom of the groove in the figure.

Fig. 4 shows an elevator system with a first elevator car 5.1 and a second elevator car 5.2, which are arranged alongside one another in a common elevator shaft 2. Both the first elevator car 5.1 and the second elevator car 5.2 have evacuation doors 20.1, 20.2. A first evacuation door 20.1 corresponding to the first elevator car 5.1 and a second evacuation door 20.2 corresponding to the second elevator car 5.2 face each other. On each of the two evacuation doors 20.1, 20.2, a device for evacuating people can be arranged as shown in fig. 2 or as shown in fig. 4. Alternatively to this, the arrangement according to fig. 3 can be arranged on the respective balustrade of both elevator cars.

Thus, a first of the two devices is arranged on the first evacuation door 20.1 and a second of these devices is arranged on the second evacuation door 20.2. In the elevator shaft 2, a plurality of fixed carriers 60.1, 60.2 are arranged vertically above one another between the travel paths of the first elevator car 5.1 and the second elevator car 5.2. On such a fixing carrier 60.1, 60.2, guide rails, not shown, for guiding the elevator car in the vertical direction can be fixed in the elevator shaft 2.

The first elevator car 5.1 is blocked, for example, in the elevator shaft 2, wherein the second elevator car 5.2 can also be moved vertically. This means that a vertical movement of the first elevator car 5.1 is not possible, after which the people trapped in the first elevator car 5.1 have to be evacuated. Such a blocked state of the first elevator car 5.1 can be caused mainly by a power failure, a lightning strike or a failure of the shaft door contact which opens the safety circuit, although the shaft door with this shaft door contact is closed. The second elevator car 5.2 can be positioned in the elevator shaft 2 in such a way that people can evacuate from the blocked first elevator car 5.1 into the second elevator car 5.2 through a people path 55 that can be fixed to both devices.

The first end of the people corridor 55 is fixed or suspended on the crosspiece 48.01 of the first of the two devices and, with its second end opposite the first end, on the footboard element 46.2 of the second of the two devices, so that the process of traversing the people corridor 55 is limited as little as possible by the persons to be evacuated. If the walkway 55 is fixed or suspended on the foot elements 46.1, 46.2 of both devices, such a crossing is understandably limited irrespective of the vertical positioning of the second elevator car 5.2, because when crossing the walkway 55, a person must climb up the lower one of the two fixing carriers 60.1 shown in fig. 4 or climb under the lower fixing carrier, which in turn increases the risk of a collision of the person entering the elevator shaft 2.

This means that the second elevator car 5.2 can be positioned in relation to the blocked first elevator car 5.1 in connection with the positioning of the evacuation-impeding fixed carrier 60.1 in the elevator shaft 2 for evacuation. After opening the second evacuation door, the service technician of the evacuation person can remove the safety barrier 52.2 of the second device to open the safety contacts corresponding to the second elevator car 5.2 or to interrupt the corresponding safety circuit. The safety contacts of this safety barrier 52.2 can also be designed in such a way that: the safety circuit corresponding to the first elevator car 5.1 is likewise interrupted in order to reliably prevent the first elevator car 5.1 from moving in the exemplary case of the end of the interruption in the supply of power. If necessary, the people corridor 55 can be fastened or suspended with its first end on the footboard element 46.1 or on one of the rails 47.01, 48.01, 49.01 fastened in the evacuation channel. The crosspiece 49.01, which can be fixed at the first end of the fixed people aisle 55, needs to be as far away as possible for evacuating people, in order not to raise additional obstacles, which appear as such a crosspiece 49.01. In order to achieve a comfortable crossing of the people aisle 55 for the people to be evacuated, a rail 47.01 which can be fixed below the first end of the fixed or suspended people aisle 55 can be fixed within the evacuation channel.

The method described below for evacuating a blocked elevator car 5.1 is suitable both for elevator systems with only a blocked first elevator car 5.1 and also for elevator systems with a further second elevator car 5.2. In order to perform evacuation from the first elevator car 5.1, the service technician must put the blocked first elevator car 5.1 into a stop mode. This means that a blocked state is ensured which may be caused by a power failure or a lightning strike. This can be done, for example, by switching a main switch located in the machine room of the elevator installation. This prevents the blocked first elevator car 5.1 from being moved by the power supply which is set off again from the outside, so that a service technician working outside the blocked first elevator car 5.1 is not scared or endangered by the suddenly unlocked running first elevator car 5.1.

The service technician can then reach the blocked first elevator car 5.1. If necessary, the service technician preferably moves the second elevator car 5.2 in a service mode, so that the second elevator car 5.2 is positioned in the elevator shaft 2 in such a way that people are evacuated from the blocked elevator car 5.1 into the second elevator car 5.2 via a walkway 55 which can be fixed on one of the first elevator car 5.1 and the second elevator car 5.2. After the safety technician has ensured that he does not fall into the elevator shaft 2, the safety technician can remove the safety rail 52.02 that is present at the second elevator car 5.2 if necessary. Subsequently, the service technician places the people corridor 55 such that the first end of the people corridor 55 is fixed or suspended on the first elevator car 5.1, either on the footboard element 46.1 or on one of the rungs 47.0, 48.0, 49.0 of the device for evacuation. The second end of the people corridor 55 is preferably suspended or fixed on a footboard element 46.2 fixed on the second elevator car 5.2. Alternatively, the second end can also be suspended or fixed on one of the rails 47.02, 48.02 fixed to the second elevator car 5.2. If evacuation of the persons located in the first elevator car 5.1 to the second elevator car 5.2, which is present if necessary, does not occur, the second end of the walkway 55 is fixed in the elevator shaft 2 as far as possible at the shaft exit. Subsequently, the safety barrier 52.1 can be removed in order to make the people aisle 55 accessible to the persons to be evacuated and to enable evacuation.

In a similar manner, the arrangement of the elevator system described with reference to fig. 4 is also suitable for evacuating a trapped person into the movable first elevator car 5.1 in the event of a blockage of the second elevator car 5.2.
