Definitions

  • the invention relates to an escalator with a safety device, according to the preamble of claim 1.
  • the invention is based on the object To create escalator with security device that the Abuse of the handrail of the escalator is significantly more difficult and the risk of accidents on the escalator is drastically reduced.
  • the invention Safety device can also be used on escalators leaves that are aesthetically particularly successful and a balustrade glass pane exhibit.
  • the sensor or sensors can do well in the area of the balustrade base outside the escalator be attached and have a detection range that extends obliquely upwards / outwards from this point. In order to such a sensor can handle all objects, including Body parts, grasp that outside of the top outer edge the balustrade, while the handrail gripping The passenger's hand remains undetected.
  • Proximity sensors such as ultrasonic sensors, are equipped in this way be sensitive to direction so that for example, all objects in the area of the balustrade are detected while a low threshold clearly above the balustrade by chance over the balustrade extended arm desirably remains undetected.
  • An ultrasonic sensor is preferred as a proximity sensor, it being understood that any other sensors, such as photo sensors or radar sensors, can also be used according to the invention.
  • high-quality configuration is a Image sensor provided during the operation of the escalator carries out ongoing image surveillance and upon detection of a an object indicating a security risk, such as a foot, Leg or the like triggers an alarm and the escalator switches off.
  • a security risk such as a foot, Leg or the like
  • the solution according to the invention is further characterized in that that escalators already installed can also be used corresponding sensors and control devices that as Safety device can be prefabricated, can be retrofitted are so that an escalator operator is able to Need to increase the safety of his escalators, for example if the usage situation changes and an increased number children playing.
  • the escalator 10 shown in Fig. 1 has a handrail 12 on the on a balustrade 14 in a conventional manner is led.
  • the handrail 12 extends on the balustrade 14 and surrounds the balustrade head 16 via a handrail wrap-around arch 18th
  • Fig. 1 Escalator has a balustrade glass pane, it being understood that the solution according to the invention also can be used on escalators with a fixed balustrade.
  • the escalator 10 has two parallel and spaced apart Balustrades on between which are in themselves known way extends the band of steps in the figures is not shown. According to the outside of the escalator, So beyond the step band, a sensor 20 and in a further sensor 22 in the exemplary embodiment shown attached, the sensors 20 and 22 are intended to paint over the area of the outside of the balustrade.
  • the sensors 20 and 22 are designed as ultrasonic sensors.
  • the sensor 20 has a sensor axis 24 and the sensor 22 a sensor axis 26 on.
  • the sensor axis 24 extends to the upper end of the Balustrade head diagonally upwards to the entry area the escalator, while the sensor axis 26 is below the Handrail extends over the course of the escalator.
  • Both sensors 20 and 22 thus have detection areas, that complement each other.
  • the sensor 20 is used to detect Body parts that are already in the area of the balustrade head or handrail transfer sheet 18 outside the balustrade are located.
  • the sensor 22 serves to detect Body parts that are only after the boarding area outside the Get to the escalator.
  • all sensors used are connected in the manner of an OR circuit: if an object, in particular a body part, of one of the sensors is detected, the alarm, for example in Form of an acoustic and / or optical signal, triggered and / or the escalator is stopped. This is preferably done Stopping the escalator particularly slowly to prevent that a child hanging on the balustrade by one too abrupt braking slips.
  • the type of sensors and especially their directional characteristics can be used in a wide range of requirements to adjust.
  • the sensor 20 provided in FIG. 1 preferably has a slightly broader polar pattern on the Sensor 22 is a highly focused and accordingly narrower Has characteristic.
  • the directional characteristics of both sensors are shown in FIG a standardized representation, i.e. the sensitivity of the Sensors depending on the detection angle related to the detection axis.
  • the representation refers to the same distance from that respective sensor, an exemplary value for a such measurement is 1.50 meters.
  • the directional characteristic 30 of the sensor 22 is quite high at low angular degrees Values and runs quite flat. In the angular range of ⁇ 5 ° so that the sensor 22 has a fairly high sensitivity, whereby this also means that the range of the sensor is comparative is high.
  • Its directional characteristic 32 is such that the sensitivity even when measured in the sensor axis 24 lower Values as the directional characteristic 30 of the sensor 22 assumes. However, the angular sensitivity is significantly reduced that the entire entrance area of the escalator from sensor 20 is swept over.
