Definitions
- Safety device at the entry point of a revolving handrail of an escalator, a moving walk or the like.
- the invention relates to a safety device at the entry point of an encircling handrail of an escalator, an escalator or the like into a fixed parapet.
- Escalators and escalators have a safety device in the area of the entry point of the rotating handrail, since it has been shown that people, especially children, who are traveling on an escalator hold on to the handrail from time to time until their hand reaches the entry point of the handrail fixed parapet. In such a case it can happen that the fingers are drawn into the gap which is located between the surface of the handrail and the inlet opening in the parapet. Without special security measures, there is a risk of serious injuries.
- DE-PS 20 54 640 proposes a safety device which has a plurality of plates which are arranged in the manner of flaps and which are pivotable at the inlet point. If the handrail is still held by a person in the area of the entry point, the fingers' contact with the plates causes them to pivot, whereby the contact of a safety switch is actuated to stop the escalator.
- the known safety device also provides for the use of two pivotable plates arranged one behind the other at a short distance.
- the distance between the handrail and the inner edge of the first plate is dimensioned so large that fingers can get into this gap without injuries.
- the object of the invention is to create a safety device for an emergency stop of the drive when objects (fingers or the like) enter the handrail inlet, and the shutdown should also take place when the handrail is torn or unclamped.
- the safety device should have a simple structure and be easily accessible.
- the downstream limit switch can be actuated in time so that a danger to persons can be largely excluded.
- the movement sequence of the rod is influenced by a mechanically pretensionable pretensioning device. This means that the limit switch is actuated only at a predetermined force acting on the elastic area of the handrail inlet. This measure can ensure that the escalator or
- the safety device is simple in structure and easily accessible, the mechanical pretensioning of the pretensioning device being able to be set or adjusted without problems.
- FIG. 1 shows a front view
- FIG. 2 shows a side view of the safety device 1.
- the safety device 1 is provided in the region of an end plate 2 of an escalator parapet (not shown in more detail).
- the balustrade 3 is only indicated in the form of a glass pane.
- a recess 4 is provided which serves to receive a handrail inlet part 5.
- the handrail inlet part 5 is provided in the region of the inlet point 6 for the handrail 7, which is only indicated here, with an elastic bellows 8, which is provided with an angled component 9 in its rear region.
- a rod 12 is connected to the free leg 11 of the component 9, which has a switching link 13 in its free end region, which in turn is formed with a conically tapering recess 14, the tip 15 of which on the plunger 16 Limit switch 17 rests.
- the rod 12 is arranged essentially vertically and is guided relative to the end plate 2 via further connecting elements 18, which in turn are screwed to the end plate 2.
- the further connecting elements 18 include a guide 19 which is provided for receiving a rubber spring element 20.
- the rubber spring element 20 is surrounded by a lateral boundary wall 21 and a lower boundary wall 22, a cup-shaped plate 23 resting on the rubber spring 20 from above.
- a further rubber spring 24 is provided below the bottom 22, one end face of which
- the safety device 1 thus responds only at a predetermined pressure acting on the bellows 8, so that it is ensured that the emergency shutdown of the escalator does not occur each time the bellows 8 is inadvertently touched. As a result of the force acting on the bellows 8, the latter is compressed, and as a result of this compression process a change in the length of the rod 12 is brought about with the corresponding triggering of the limit switch.
