Definitions
- the invention relates to an escalator or moving walk, according to the preamble of claim 1.
- the handrails For escalators or moving walks, the handrails must comply with the regulations moved synchronously with the step or pallet belt become.
- the handrails consist of endless rubber or plastic bands, which are provided with tension members and reinforcements, have a C-shaped cross-section and on specially shaped Glide handrail guide profiles.
- balustrades While in the past closed sheet steel balustrades were common, which looked broad and bulky more and more balustrades made of safety glass enforced more.
- a clamping plate is placed on the balustrade forming glass plate
- the handrail is supported by roller bearings and serves as a sliding guide.
- the clamping plate extends to the side of the balustrade in a U-shape to the ends of the C-shaped cross section of the handrail there.
- the inclined deflector surface should be the vertical one Overlap the gap between the handrail and the clamping profile on the side.
- the disadvantage here is that instead of the vertical Gap now creates a horizontal gap, which at accidental lifting of the handrail due to the for the Operation required game after all in the order of magnitude from several mm to 1 cm wide.
- the invention is therefore based on the object of an escalator or a moving walk according to the preamble of claim 1 to create improved security against tampering allows easy manufacture and both in the area of Balustrade head as well as used in the course of the balustrade can be.
- the gap between the End of the handrail and the clamping plate or the like from Brushes forming soft elements that are covered over the entire length of the exposed handrail in one extend special shape, or as other soft elements.
- Such elements are surprising both Risk of intervention drastically reduced, as well as with the corresponding Design the protection function against umbrellas, Sticks and the like ensured.
- the ends of the bristles practice the passenger, should he put his fingers in the Area, sensory stimuli such that this involuntarily pulls back the hand quickly and so before the clamping and Risk of crushing is protected.
- a clamp bracket serves as a brush bezel.
- the Clamp bracket consists of a U-shaped sheet with Clamping grooves at the end, as is known for brushes.
- the bristles are preferably bent slightly outwards so that they are at an angle of about 30 ° to 80 °, based on the Horizontal, extend towards the handrail.
- This configuration allows the clamping profile to be known Way with sloping but fairly flat lower legs train so that the shapely design of a glass balustrade escalator can be obtained.
- the The angle of attack of the brushes is also steeper from the outset be so that the same result can be achieved.
- Measures to preform a brush are known. For example can when using plastic bristles after completion the brush this one-sided heat treatment Facility to be subjected to alignment the brush results in the desired manner.
- the brush tapes located on the curves of the balustrade heads it is particularly favorable that the brush tapes located on the curves of the balustrade heads.
- it is not just the brushes that act as a deflector. Rather, the lower leg of the clamp bracket forms one additional deflecting surface, it being particularly favorable that it also extends over the gap.
- This configuration also enables a uniform appearance for the escalator or moving walk by using the clamp bracket with the brush according to the invention over the entire visible Length of the handrail extends.
- the bristles of the brushes can be of a preferred embodiment extend slightly diagonally following the direction of travel.
- individual bristles, especially the outer bristles should be kept a little longer, and the rejection function for manual intervention is guaranteed.
- there is also an entrainment effect least for the bristles on the underside of the handrail if the handrail is pressed down so far that it comes into contact with the bristle ends. It is preferred that in the normal position no contact between the bristle ends and the handrail, while on the other hand the touch there is not critical, induces only very low frictional forces and generates practically no wear.
- a soft element according to the invention preferably consists of a Brush in a clamp, in particular from a U-shaped Sheet steel is held.
- the manufacture of such Brush is preferably made so that a prefabricated bristle band is used, which is in the U-shaped, pre-bent Clamp bracket is inserted. In this state, the Bristles through the somewhat pinching clamping grooves of the clamping bracket held. Fastening screws pass through both side legs the U-shaped clamp bracket and serve the to attach the brush according to the invention to the handrail guide profile.
- the tuft protruding from the clamp bracket the bristle band is then suitably heated and bent so that the bristles at their free ends more upward point.
- the clamp bracket is under tension, the clamping grooves the row of bristles approximately in the middle of the length of each bristle holds on.
- a slight inclination of the bristles in Direction of travel can be done before the final assembly of the bristle band achieve that on the example Textile fabric existing bristle band end of the bristles is pulled against the direction of travel.
- the bristles swivel then around the clamping grooves as a contact point and lay something diagonally following the direction of travel. In this state the clamp bracket is then tightened by the screw connections and thus the brush according to the invention finally determined.
- the brush according to the invention is also low-wear, since it is in the Normal operation is not touched by the passengers, and one Passenger who accidentally enters the intrusion protection area that is dangerous for him of the handrail engages immediately the brush noticed and involuntarily withdraws his hand. It understands furthermore that the brush according to the invention both from Metal, but preferably can be made of plastic and the individual bristles have a low coefficient of static friction should have.
- An escalator according to the invention or an inventive one Moving walk 10 has a glass balustrade 12, the upper one End of a clamp profile or handrail guide profile 14 is covered, on which a handrail 16 via roller bearings 18 and 20 is movably mounted.
- the handrail has the shape of a lying C, is in its mid-leg is fiber-reinforced and points to the side Cranks 24 and 26, the cranks 28 and 30 end up.
- the clamping profile 14 is with an area that has the shape of a reversed U, clamped on the glass balustrade.
- U-shaped areas extend to the side of this central area, which serve to accommodate the roller bearings 18 and 20.
- the U-shaped areas 32 and 34 each have an inclined position Middle leg 36 and 38 on the slightly oblique from the elbow 28 and 30 runs to the glass balustrade 12.
- a brush 48 and 50 extends below the middle legs 36 and 38, is fastened there and with the ends of its bristles 52 and 54 beyond column 44 and 46 ends.
- Brushes 48 and 50 each have a clamp bracket 56 and 58, which are bent into a U-shape is. At the open ends of the clamp brackets 56 and 58 are clamping grooves 60 and 62 provided in the brushes the bristles 52 and 54 are known at this point wrap up and hold on.
- the bristles 52 and 54 are each on a bristle band 64 and 66 interconnected, which facilitates assembly.
- a screw connection 68 is shown schematically in the figure is.
- the screw connection acts between the one in the Figure shown below leg of the clamp bracket 58 and the middle leg 38 of the handrail guide profile 14, so that the bristles 54 are securely locked.
- bristles 52 and 54 end in a tuft that is due to the effect of the clamping grooves 60 and 62 is spread, whereby in the illustrated embodiment, the ends of the bristles 52 and 54 end just before the elbow ends 28 and 30.
- the transition between the glass balustrade 12 and the brushes 48 and 50 with a sealing compound filled like epoxy resin which is equally for the downward facing area of the clamping grooves 60 and 62 applies. It is particularly favorable here that a in the area of Balustrade head, umbrella tending towards jamming, stick or the like, already from the clamp bracket 56 or 58 is derived across the gap 44 and 46 while the Bristles 52 and 54 do the rest to continue the derivation.
