Definitions
- the invention relates to a passenger conveyor system, such as an escalator or a moving walkway, comprising a handrail and a safety device for monitoring the handrail according to the generic part of the first claim.
- US-A 5,072,820 relates to a safety device for the handrail Passenger conveyor system, whereby a sensor is used, which at a stop the handrail switches off the continuation of the step belt.
- US-A 2,885,057 is a handrail guide device for both flat and handrails with wedges can also be removed.
- the handrail will do this guided around various deflection pulleys outside the visible area.
- EP-A 0 960 847 is an escalator or moving walk with a Handrail monitoring device has become known.
- This handrail will the steel cable insert serving as reinforcement by means of an inductive Proximity switch detected.
- This type of detector is only for handrails can be used, which are provided with metallic inserts. If there is a handrail an inductive sensor can be used to reinforce it on a textile basis Not used.
- handrails which, analogous to US-A 2,885,057 in the lower area is equipped with wedge-shaped profiles inductive detectors not useful, because the distance detector-steel insert is very is great. An increased technical measurement effort would have to be carried out here.
- the object of the invention is to provide a safety device Monitoring the handrail for an escalator or moving walk to provide through which, in particular caused by vandalism Lifting the handrail from the handrail guide recognized and the drive of the Passenger conveyor system within the framework of the applicable safety regulations can be stopped.
- the safety device is intended for all types of Handrails can be used.
- the senor is a capacitive sensor is, which includes an elongated sensor part that is non-contact in the area below the handrail is positioned.
- the safety device according to the invention can at any point Handrail guidance can be provided, with the preferred application in lower transition area seen from the horizontal to the inclined plane is, because - as already mentioned - here the most endangered area with the greatest burden is given.
- a capacitive sensor is used as the sensor, since it is not only used for Handrails with or without steel reinforcement, but also with handrails with Wedges can be used in a simple manner.
- the senor is non-contact provided for the handrail below it and is directly or indirectly with connected to the handrail guide.
- the sensor contains a self-supporting sensor part that is contact-free underneath the handrail is positioned, the sensor being at a predetermined maximum lifting value of the handrail as a switch-off criterion for driving the Passenger conveyor is set. Regardless of whether the handrail is at least partially removed, the drive for the step belt at If this maximum value is exceeded, switched off.
- Figures 1 and 2 show handrails 1, 2 with different designs Handrail guides 3,4 are operatively connected.
- Handrail 1 includes on the inside a wedge 5 which projects into the associated handrail guide 3, while the handrail 2 is flat on the inside.
- Each handrail guide 4 has guide elements 6, 7 on the handrail side.
- the handrail guides are 3.4 via further components 8.9, for example with a glass balustrade 10.11 connected.
- a capacitive sensor 12, 13, which is indirectly indicated, is indicated Screws 14.15 are operatively connected to the handrail guide 3.4.
- the sensor 12, 13 is in the visible area of the handrail 1, 2 below it positioned. Function and mode of operation of the sensor 12, 13 will be described in the following Figures explained in more detail.
- Figures 3 and 4 show handrail guides 3 '(partly in section) that are similar are constructed for Figure 1.
- the handrail guide 3 ' also includes here Guide elements 6 'and is with other components 8' via a screw 14 ' connected.
- a sensor 12 ' which has an elongated sensor part 16 which is non-contact, i.e. at a distance, below the spline 5 'of Handrail 1 'is positioned.
- the capacitive sensor 12 ' (not shown) over appropriate signal lines connected to the main drive of the escalator.
- the sensor 12 ' is preferably - as shown in Figure 4 - in the lower Transition area 10 of the passenger conveyor system positioned, in particular in this critical area, where the handrail 1 'strives to be straight, higher forces on the guide elements 6 'of the handrail guide 3' or the part 18 of the handrail 1 'act. Taking this fact into account, it is possible, the part 18 of the handrail 1 'in this area 17 more easily from that Lever off guide element 6 'than, for example, in a rectilinear area.
- the sensor 12 ' is, for example, above a potentiometer (not shown) a predeterminable lift-off value (for example 5 mm) of the handrail 1 ' set and automatically switches the when this value is exceeded Main drive of the passenger conveyor system.
- the sensor part 16 should be in this Example are operatively connected to a supporting metal part 16 ', in particular be glued to it. The metal part 16 'is then over a screw 14 connected to the handrail guide 3 '.
- Figures 5 and 6 show handrail guides 4 '(partly in section) as they correspond approximately to Figure 2.
- the sensor 13 'used also includes an elongated sensor part 19, which is non-contact, i.e. With Distance, positioned below the handrail 2 'so that it is on a Metal body 19 'rests and is connected to the same, for example by gluing is. The metal body 19 'can then via the screw 15 with the handrail guide get connected.
