Description

Sengmüller, Kurt and Walter-Sinsel, Lars Hazard detection system for an elevator system, door arrangement, access portal and elevator system Description

[0001] The invention relates to a hazard detection system for an elevator system. Furthermore, the invention relates to a door arrangement and an access portal for an elevator system. The invention also relates to an elevator system.

[0002] Fire safety requirements for buildings are constantly being tightened. The elevator shaft plays a crucial role in preventing smoke from spreading within the building, as it connects all floors vertically.

[0003] To achieve a higher level of safety, rapid smoke detection is necessary for, for example, opening the smoke extraction system, alerting the fire department, and evacuating the elevators. Previously, smoke detectors were installed in the elevator shaft and on the ceiling of the vestibule in front of the elevator entrances to meet the safety objectives.

[0004] For example, document DE 10 2007 010 432 A1 discloses equipment and controls for using elevators for self-rescue in case of danger. In this document, the alarm detectors are located in the elevator shaft, on the ceiling of the vestibule, and in other building components or rooms not directly related to the elevator.

[0005] Due to the continuous development of elevators, space within the elevator shaft is becoming increasingly limited, making reliable smoke detection and installation more difficult. Furthermore, early and reliable smoke detection is essential, especially before smoke enters the elevator shaft from the outside. Immediate activation of safety devices is also desirable to ensure that fires or smoke development are detected earlier than before and that optimal measures can be taken.

[0006] The invention is based on the objective of structurally and / or functionally improving a hazard detection system mentioned above. Furthermore, the invention is based on the objective of structurally and / or functionally improving a door arrangement mentioned above and an access portal for an elevator system. Finally, the invention is based on the objective of structurally and / or functionally improving an elevator system mentioned above. In particular, it is an objective of the invention to achieve a higher level of safety. This can be achieved, for example, by detecting smoke from a fire only when it enters the elevator shaft. This prevents the smoke extraction system in the elevator shaft from opening prematurely and / or avoids the unintended spread of smoke caused by the suction effect of the smoke extraction opening.

[0007] The problem is solved by a hazard detection system having the features of claim 1. Furthermore, the problem is solved by a door arrangement or an access portal having the features of claims 15 and 16, respectively. Finally, the problem is solved by an elevator system having the features of claim 17. Advantageous embodiments and / or further developments are the subject of the dependent claims.

[0021] In summary, the invention provides, among other things, a system and / or an elevator installation, elevator doors, and / or an elevator car, wherein a fire and / or smoke detection device, such as a smoke detector, is integrated into the elevator access, shaft access, or car access, such as the door frame or door lintel. The smoke detectors can be integrated into the door frame or the door construction of the shaft doors, for example, in such a way that architectural requirements are met and / or the smoke detector is essentially not visible or recognizable. Additionally, the smoke detectors can be retrofitted as a surface-mounted or integrated as a built-in option. Upon fire and / or smoke detection, a smoke venting element for the elevator shaft can be opened.This locking element can be located in the elevator shaft, the elevator machine room, at the end of a duct, etc. In the event of a fire in the building, it can be ensured and / or provided that the elevator system is no longer used and / or that the elevator car(s) automatically travel to a specific landing or evacuate. The fire detection / alarm signal can also be used to alert the fire department. Fire and / or smoke detection can thus be provided. Hazard detectors can be positioned in elevator shafts, elevator cars, elevator lobbies, and / or integrated into the construction of elevator doors, such as shaft doors and / or car doors, or into the portals of the shaft doors. For example, a fire detection element, e.g., a smoke and / or heat detector, can be integrated in the access area of ​​the elevator car, e.g., the shaft door frame, car door frame, shaft door portal, or door jamb. The design of the hazard detectors can be designed and / or adapted for their intended use and / or installation in the aforementioned areas. The design of the fire detection elements or hazard detectors can be specifically adapted for the installation situation and / or their functionality can be tested accordingly. Installation should be as inconspicuous as possible from the outside. Fire monitoring, e.g., smoke monitoring, heat detection, etc., can be activated in the presence of smoke or heat.The fire detection is carried out in the area of ​​transition between the elevator lobby (area in front of the shaft entrance) and the elevator shaft or elevator car. The system can also be expanded with fire detection elements or hazard detectors in the elevator lobby or directly in the elevator shaft. Fire and / or smoke detection can be reported by the respective detector to a control and / or evaluation unit. The connection can be established via cabling or radio / WLAN. The detectors can also have an integrated relay that can, for example, directly execute actions via a potential-free contact, such as interrupting the power supply to a fail-safe drive or sending information to an external system such as a fire alarm control panel, building management system, etc.

[0022] The invention enables earlier fire detection, particularly because smoke and fire detection can occur outside the elevator shaft. The fire detection elements or hazard detectors can be housed and / or integrated in a space-saving manner. Installation of the fire detection elements or hazard detectors can be significantly simplified, especially since they can already be incorporated into the door element or a mounting position / receptacle can be provided. The arrangement of the fire detection elements or hazard detectors can be clearly defined, thus ensuring the intended functionality. Fire detection elements or hazard detectors can be installed in a way that is visually undetectable and therefore architecturally unproblematic. Optimal monitoring of fire events before and within the elevator shaft can be ensured. Optimal monitoring of smoke transmission between the elevator lobbies and the elevator shaft can also be guaranteed. This allows for a higher level of safety, as smoke is only detected once it enters the elevator shaft. The smoke extraction to the outside, which is particularly required by building regulations, can be initiated early. Necessary actions can then be taken, such as evacuating the elevator, opening the smoke extraction system, and transmitting the status to external (safety) systems to activate further required measures.This also prevents the smoke extraction system in the elevator shaft from opening too early and / or avoids unwanted smoke spreading due to the suction effect of the smoke extraction opening.

[0023] The present invention can thus comprise an elevator system with shaft doors, portals / access portals, and / or car doors. Hazard detectors or fire detection elements, e.g., smoke detectors, can be integrated and / or mounted, for example, concealed or visible, in the construction of the shaft doors, portals / access portals, and / or car doors. These hazard detectors or fire detection elements can serve and / or be designed for the early detection of fires. Appropriate measures can then be initiated based on the evaluation of the fire detection data.
