Definitions

the invention relates to an escalator or moving walk consisting of a balustrade, a balustrade base, Steps or plates for the transport of people and Objects, one arranged on the balustrade Handrail construction with a handrail for safety of people in a redirection area of the balustrade can be deflected by means of a drivable support disk.
a disadvantage of the known device is that the handrail drive only for encapsulated deflection wheels is usable.
the central pulley with the Drive chain must in any case for safety reasons be covered.
the invention seeks to remedy this.
the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and propose a handrail drive that also at Glass balustrades can be used.
the advantages achieved by the invention are in essential to see that in escalators or Moving walks with an elegant balustrade as a truss trained support body can be built slim.
the handrail guide be simplified and the handrail bending change minimized become.
the deflection areas can be built as slim as the balustrades and that the designer has more freedom in designing the Has deflection areas.
the truss width can be reduced and the handrail length can be shortened.
the handrail crosses no longer with the step chain.
the handrail intermediate shaft and chain lubrication devices are eliminated.
1 is a deflection area Escalator or an escalator referred to essentially a balustrade base 2, a balustrade 3 and a handrail 4.
Escalator or an escalator referred to essentially a balustrade base 2, a balustrade 3 and a handrail 4.
For the transport of People and objects are level 5 on an escalator or provided on a moving walk plates 5, each depending on of the cheek side reach the balustrade base 2.
the Step side or plate side of the balustrade 3 is in further with transport side 6 and the outside of the Balustrade 3 designated 7.
Balustrade 3 made, for example, of glass with a wall thickness of about 10 mm, which is the escalator or moving walk gives slim, light, elegant look.
Fig. 1 shows a deflection of the handrail 4 by means of a about an axis 9 rotating, for example transparent Support disc 10, with a wall thickness that is about the Wall thickness of balustrade 3 corresponds.
the axis 9 will of at least one, for example transparent Support cheek 11 held, for example, by means of a Welded connection 12 with the support structure of the Handrail 4 and / or for example by means of a screw or Rivet connection 13 is connected to the balustrade 3.
the axis 9 is on the outside 7, for example by means of a screw or rivet connection 13 with the Carrier cheek 11 connected, like the carrying cheek 11 of the Transport side 6 by means of the welded connection 12 a support 14 of the handrail construction is connected. at transparent support cheeks 11 can be in the peripheral area Support disc 10 may be dark tinted.
the ever support 14 arranged on one side of the support disk 10 has at one end a sliding surface 15 on which the handrail 4 slides and is guided on the outside. In the middle the handrail 4 carried by the rotatable support disc 10 and redirected.
the support disc 10 is by means of a bearing 16 rotatably mounted on the axis 9.
Fig. 3 shows the integrated in the balustrade base 2 Handrail drive 20 consisting of, for example Electric motor 21 by means of a chain 22 or by means of a belt 22 (toothed belt, V-belt, flat belt, Studded belt) drives a drive wheel 23.
the support disc 10 is driven peripherally by the drive wheel 23.
the Handrail 4 guided over a deflection wheel 24 is carried out Friction taken away from the support disc 10.
the Electric motor 21 can be a torque motor or by means of of a control loop with a step chain 26.1 or one Step chain motor be synchronized.
the section B-B shown in Fig. 4 illustrates the Arrangement of the handrail drive 20 in the balustrade base 2 and the peripheral, front-side drive of the support disk 10 by means of the drive wheel 23.
the one with the Step chain 26.1 step 5 connected on both sides with the Rollers 25,26 shown on a on the structure 27th unroll the arranged guide 26.2.
FIG. 5 and 6 show the one according to the invention Handrail drive 20 with an intermediate shaft 28, the Intermediate shaft 28 by means of a chain chain driving Main shaft 29 can be driven.
the power transmission from Wave to wave or from the intermediate shaft 28 to one Transmission wheel 30 is made by means of chains 31 or belts 31 (Timing belts, V-belts, flat belts, nub belts), where the transmission wheel 30 drives the drive wheel 23.
Fig. 6 shows the handrail drive 20 without transmission wheel 30, wherein the power transmission from the intermediate shaft 28 directly on the drive wheel 23 takes place by means of a crossed belt 32.
Fig. 8 shows a drive wheel 23 with a smooth surface as Friction surface by means of which the support disk 10 can be driven.
the drive wheel 23 is not on one, for example shown pendulum arm arranged by means of a Spring force of a spring 34 can be acted upon, the Drive wheel 23 is pressed against the support disk 10.
the required contact pressure on the Friction contact point 33 generated.
the Spring force of the spring 34 for example, pneumatically or can be hydraulically reinforced or weakened.
Fig. 9 shows the drive wheel 23 with a smooth surface as Friction surface and the support plate 10 with a cord or Knurled or a cross knurled surface 35 as a friction surface
the drive wheel 23, for example, a rubberized one Roll is made of polyurethane and is slim and therefore extremely light support plate 10 drives spring loaded. With the above surface of the support disc the friction at the friction contact point 33 improves and reduces the risk of slipping.
Fig. 10 shows the drive wheel 23 with a Spur gear teeth 36, with the support disk 10 also has straight teeth.
the Touch point 37 is located on the gear pitch circle and is form-fitting.
the gears are with lots of little ones Teeth equipped because of damage to the handrail 4 would be given by large teeth.
the inside of the Handrail 4 or the sliding position is due to the small Teeth on the large diameter of the support plate 10 hardly damaged.
the handrail 4 is driven comparable to a multi-stage gear transmission, whereby the handrail 4 is engaged with the last gear.
mounting bracket 38 holds that Drive wheel 23 at a certain distance from the support disc 10 fixed, the distance is adjustable.
