Description

Die Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig bestehend aus einer Balustrade, einem Balustradensockel, Stufen bzw. Platten für den Transport von Personen und Gegenständen, einer an der Balustrade angeordneten Handlaufkonstruktion mit einem Handlauf für die Sicherheit der Personen, der in einem Umlenkbereich der Balustrade mittels einer antreibbaren Stützscheibe umlenkbar ist.The invention relates to an escalator or a moving walkway consisting of a balustrade, a balustrade base, steps or plates for the transport of persons and objects, arranged on the balustrade handrail construction with a handrail for the safety of persons, in a deflection of the balustrade means a drivable support disk is deflected.

Aus der Patentschrift US 2 373 764 ist eine Fahrtreppe bekannt geworden, bei der ein Handlauf über ein oberes, den Handlauf antreibendes und ein unteres, freilaufendes Umlenkrad geführt ist. Das obere Umlenkrad weist ein mit dem Umlenkrad koaxiales Pulley auf, das mittels einer Kette antreibbar ist, wobei die Kette mittels eines Pulleys des Umlenkrades für die Stufenkette antreibbar ist. Die Antriebsenergie für die Stufenkette stammt von einem Elektromotor mit Getriebe. US 785882 offenbart einen Handlaufantrieb, der eine Stützscheibe peripher antreibt.From the Patent US 2 373 764 an escalator has become known in which a handrail is guided over an upper, the handrail driving and a lower, freewheeling guide wheel. The upper deflection wheel has a pulley which is coaxial with the deflection wheel and which can be driven by means of a chain, wherein the chain can be driven by means of a pulley of the deflection wheel for the step chain. The drive energy for the step chain comes from an electric motor with gearbox. US 785882 discloses a handrail drive which peripherally drives a support disc.

Ein Nachteil der bekannten Einrichtung liegt darin, dass der Handlaufantrieb nur für gekapselte Umlenkräder verwendbar ist. Das zentral angeordnete Pulley mit der Antriebskette muss in jedem Fall aus Sicherheitsgründen abgedeckt sein.A disadvantage of the known device is that the handrail drive is usable only for encapsulated deflection wheels. The centrally arranged pulley with the drive chain must always be covered for safety reasons.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und einen Handlaufantrieb vorzuschlagen, der auch bei Glasbalustraden eingesetzt werden kann.The invention aims to remedy this situation. The invention, as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to propose a handrail drive, which can also be used in Glasbalustraden.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass bei Fahrtreppen oder Fahrsteigen mit eleganter Balustrade der als Fachwerk ausgebildete Tragkörper schlank gebaut werden kann. Ausserdem kann dank des direkt auf das Umlenkrad einwirkenden Handlaufantriebes die Handlaufführung vereinfacht werden und die Handlaufbiegewechsel minimiert werden. Weiter vorteilhaft ist, dass die Umlenkbereiche ebenso schlank gebaut werden können wie die Balustraden und dass der Konstrukteur mehr Freiheit in der Gestaltung der Umlenkbereiche hat. Die Fachwerkbreite kann verringert und die Handlauflänge verkürzt werden. Der Handlauf kreuzt nicht mehr mit der Stufenkette. Die Handlaufzwischenwelle und Kettenschmiereinrichtungen entfallen.The advantages achieved by the invention are essentially to be seen in the fact that in escalators or moving walkways with elegant balustrade designed as a truss supporting body can be built slim. In addition, the handrail guide can be simplified and the handrail bending changes can be minimized thanks to the handrail drive acting directly on the diverter wheel. Another advantage is that the deflection can be built as slim as the balustrades and that the designer has more freedom in the design of the deflection. The truss width can be reduced and the length of the handrail shortened. The handrail no longer crosses the step chain. The handrail intermediate shaft and chain lubrication omitted.

In den Fig. 1 bis 10 ist mit 1 ein Umlenkbereich einer Fahrtreppe oder eines Fahrsteiges bezeichnet, die bzw. der im wesentlichen einen Balustradensockel 2, eine Balustrade 3 und einen Handlauf 4 aufweist. Für den Transport von Personen und Gegenstände sind bei einer Fahrtreppe Stufen 5 bzw. bei einem Fahrsteig Platten 5 vorgesehen, die je an der Wangenseite an den Balustradensockel 2 reichen. Die Stufenseite bzw. Plattenseite der Balustrade 3 ist im weiteren mit Transportseite 6 und die Aussenseite der Balustrade 3 mit 7 bezeichnet.In the Fig. 1 to 10 1 is a deflecting area of an escalator or moving walk, which essentially has a balustrade base 2, a balustrade 3 and a handrail 4. For the transport of persons and objects at an escalator stages 5 or at a moving platform plates 5 are provided, which each extend to the cheeks side to the balustrade base 2. The step side or plate side of the balustrade 3 is referred to in the other with the transport side 6 and the outside of the balustrade 3 with 7.

Bei heutigen Fahrtreppen bzw. Fahrsteigen besteht die Balustrade 3 aus beispielsweise Glas mit einer Wandstärke von etwa 10 mm, was der Fahrtreppe bzw. dem Fahrsteig ein schlankes, leichtes, elegantes Aussehen verleiht.In today's escalators or moving walkways, the balustrade 3 consists of, for example glass with a wall thickness of about 10 mm, which gives the escalator and the moving walk a sleek, lightweight, elegant look.

Fig. 1 zeigt eine Umlenkung des Handlaufes 4 mittels einer um eine Achse 9 drehenden, beispielsweise transparenten Stützscheibe 10, mit einer Wandstärke, die etwa der Wandstärke der Balustrade 3 entspricht. Die Achse 9 wird von mindestens einer, beispielsweise transparenten Tragwange 11 gehalten, die beispielsweise mittels einer Schweissverbindung 12 mit der Stützkonstruktion des Handlaufs 4 und/oder beispielsweise mittels einer Schrauboder Nietverbindung 13 mit der Balustrade 3 verbunden ist. Fig. 1 shows a deflection of the handrail 4 by means of a rotating about an axis 9, for example, transparent support plate 10, with a wall thickness which corresponds approximately to the wall thickness of the balustrade 3. The axis 9 is held by at least one, for example, transparent supporting cheek 11, which is connected for example by means of a welded connection 12 to the supporting structure of the handrail 4 and / or for example by means of a screw or rivet connection 13 with the balustrade 3.

Fig. 2 zeigt Einzelheiten der Umlenkung des Handlaufs 4. Die Achse 9 ist auf der Aussenseite 7 beispielsweise mittels einer Schraub- oder Nietverbindung 13 mit der Tragwange 11 verbunden, die wie auch die Tragwange 11 der Transportseite 6 mittels der Schweissverbindung 12 mit einer Stütze 14 der Handlaufkonstruktion verbunden ist. Bei transparenten Tragwangen 11 kann im peripheren Bereich der Stützscheibe 10 eine Dunkeltönung vorgesehen sein. Die je auf einer Seite der Stützscheibe 10 angeordnete Stütze 14 weist an ihrem einen Ende eine Gleitfläche 15 auf, an der der Handlauf 4 aussen gleitet und geführt wird. Mittig wird der Handlauf 4 von der drehbaren Stützscheibe 10 getragen und umgelenkt. Die Stützscheibe 10 ist mittels eines Lagers 16 an der Achse 9 drehbar gelagert. Fig. 2 shows details of the deflection of the handrail 4. The axis 9 is connected on the outside 7, for example by means of a screw or rivet 13 with the support cheek 11, which connected as well as the support beam 11 of the transport side 6 by means of the welded connection 12 with a support 14 of the handrail construction is. In transparent support cheeks 11, a darkening may be provided in the peripheral region of the support disk 10. The each arranged on one side of the support plate 10 support 14 has at its one end a sliding surface 15 on which the handrail 4 slides outside and is guided. In the middle of the handrail 4 is supported by the rotatable support plate 10 and deflected. The support disk 10 is rotatably supported by means of a bearing 16 on the axis 9.

Fig. 3 zeigt den im Balustradensockel 2 integrierten Handlaufantrieb 20 bestehend aus beispielsweise einem Elektromotor 21, der mittels einer Kette 22 oder mittels eines Riemens 22 (Zahnriemen, Keilriemen, Flachriemen, Noppenriemen) ein Antriebsrad 23 antreibt. Die Stützscheibe 10 wird durch das Antriebsrad 23 peripher angetrieben. Der über ein Ablenkrad 24 geführte Handlauf 4 wird durch Friktion von der Stützscheibe 10 mitgenommen. Der Elektromotor 21 kann ein Drehmomentmotor sein oder mittels eines Regelkreises mit einer Stufenkette 26.1 bzw. eines Stufenkettenmotors synchronisiert sein. Fig. 3 shows the built-in balustrade base 2 handrail drive 20 consisting of, for example, an electric motor 21, which drives a drive wheel 23 by means of a chain 22 or by means of a belt 22 (timing belt, V-belt, flat belt, knob belt). The support disk 10 is driven peripherally by the drive wheel 23. The guided over a deflector 24 handrail 4 is taken by friction of the support plate 10. The electric motor 21 may be a torque motor or be synchronized by means of a control loop with a step chain 26.1 or a step chain motor.

Der in Fig. 4 gezeigte Schnitt B-B verdeutlicht die Anordnung des Handlaufantriebes 20 im Balustradensockel 2 und der periphere, stirnseitige Antrieb der Stützscheibe 10 mittels des Antriebsrades 23. Ausserdem ist die mit der Stufenkette 26.1 beidseitig verbundene Stufe 5 mit den Laufrollen 25,26 gezeigt, die auf einer am Tragwerk 27 angeordneten Führung 26.2 abrollen.The in Fig. 4 shown section BB illustrates the arrangement of the handrail drive 20 in the balustrade base 2 and the peripheral frontal drive of the support plate 10 by means of the drive wheel 23. In addition, the step chain 26.1 connected on both sides stage 5 with the rollers 25,26 shown on a support structure 27 arranged guide 26.2 unroll.

Fig. 5 und Fig. 6 zeigen den erfindungsgemässen Handlaufantrieb 20 mit einer Zwischenwelle 28, wobei die Zwischenwelle 28 mittels einer die Stufenkette antreibenden Hauptwelle 29 antreibbar ist. Die Kraftübertragung von Welle zu Welle oder von der Zwischenwelle 28 auf ein Übersetzungsrad 30 erfolgt mittels Ketten 31 oder Riemen 31 (Zahnriemen, Keilriemen, Flachriemen, Noppenriemen), wobei das Übersetzungsrad 30 das Antriebsrad 23 antreibt. Fig. 6 zeigt den Handlaufantrieb 20 ohne Übersetzungsrad 30, wobei die Kraftübertragung von der Zwischenwelle 28 direkt auf das Antriebsrad 23 mittels gekreuztem Riemen 32 erfolgt. Fig. 5 and Fig. 6 show the inventive handrail drive 20 with an intermediate shaft 28, wherein the intermediate shaft 28 by means of a step chain driving main shaft 29 is driven. The power transmission from shaft to shaft or from the intermediate shaft 28 to a transmission wheel 30 by means of chains 31 or belt 31 (timing belt, V-belt, flat belt, knob belt), the transmission wheel 30, the drive wheel 23 drives. Fig. 6 shows the handrail drive 20 without translation gear 30, wherein the power transmission from the intermediate shaft 28 takes place directly on the drive wheel 23 by means of crossed belt 32.

Fig. 7 zeigt eine Ausführungsvariante des Handlaufantriebes 20 ohne Zwischenwelle. Bei dieser Variante wird das Übersetzungsrad 30 direkt von der Hauptwelle 29 angetrieben. Der Entfall der Zwischenwelle 28 ist ein konstruktiver Vorteil und verringert die Anzahl der Bauteile. Fig. 7 shows a variant of the handrail drive 20 without intermediate shaft. In this variant, the translation gear 30 is driven directly by the main shaft 29. The elimination of the intermediate shaft 28 is a constructive advantage and reduces the number of components.

Fig. 8, Fig. 9 und Fig. 10 zeigen den Ausschnitt C der Fig. 4, der das Antriebsrad 23 und die Stützscheibe 10 detaillierter zeigt, wobei es sich um Varianten von möglichen Reibpaarungen bzw. Zahnradpaarungen handelt. Fig. 8, Fig. 9 and Fig. 10 show the detail C of the Fig. 4 showing the drive wheel 23 and the support plate 10 in more detail, which are variants of possible friction pairings or gear pairings.

Fig. 8 zeigt ein Antriebsrad 23 mit glatter Oberfläche als Reibfläche mittels der die Stützscheibe 10 antreibbar ist. Das Antriebsrad 23 ist beispielsweise an einem nicht dargestellten Pendelarm angeordnet, der mittels einer Federkraft einer Feder 34 beaufschlagbar ist, wobei das Antriebsrad 23 gegen die Stützscheibe 10 gepresst wird. Dadurch wird der benötigte Anpressdruck an der Reibberührungsstelle 33 erzeugt. Die beispielsweise aus Kunststoff, Aluminium oder Sicherheitsglas hergestellte Stützscheibe 10 und das beispielsweise aus Polyuretan, Polyamid oder Polyvinylidenflourid hergestellte Antriebsrad 23 sind als Reibpartner aufeinander abgestimmt, wobei die Federkraft der Feder 34 beispielsweise pneumatisch oder hydraulisch verstärkt oder abgeschwächt werden kann. Fig. 8 shows a drive wheel 23 with a smooth surface as a friction surface by means of the support plate 10 is driven. The drive wheel 23 is arranged for example on a pendulum arm, not shown, which is acted upon by a spring force of a spring 34, wherein the drive wheel 23 is pressed against the support plate 10. As a result, the required contact pressure is generated at the Reibberührungsstelle 33. For example, made of plastic, aluminum or safety glass Support disk 10 and the drive wheel 23, for example made of polyuretan, polyamide or Polyvinylidenflourid are coordinated as a friction partner, the spring force of the spring 34, for example, pneumatically or hydraulically amplified or attenuated.

Fig. 9 zeigt das Antriebsrad 23 mit glatter Oberfläche als Reibfläche und die Stützscheibe 10 mit einer Kordel- oder Rändel- oder einer Kreuzrändeloberfläche 35 als Reibfläche, wobei das Antriebsrad 23 beispielsweise eine gummierte Rolle aus Polyuretan ist und die schlank bauende und daher extrem leichte Stützscheibe 10 druckfederbelastet antreibt. Mit der oben genannten Oberfläche der Stützscheibe verbessert sich die Reibung an der Reibberührungsstelle 33 und vermindert die Schlupfgefahr. Fig. 9 shows the drive wheel 23 with a smooth surface as a friction surface and the support plate 10 with a cord or knurl or a Kreuzrändeloberfläche 35 as a friction surface, the drive wheel 23, for example, a rubberized roller made of polyurethane and slender construction and therefore extremely light support plate 10 is driven by compression springs , With the above-mentioned surface of the support disk, the friction improves at the Reibberührungsstelle 33 and reduces the risk of slipping.

Fig. 10 zeigt das Antriebsrad 23 mit einer Stirngeradverzahnung 36, wobei die Stützscheibe 10 ebenfalls eine Geradverzahnung aufweist. Die Berührungsstelle 37 befindet sich am Zahnradteilkreis und ist formschlüssig. Die Zahnräder sind mit vielen kleinen Zähnen ausgestattet, weil eine Beschädigung des Handlaufes 4 durch große Zähne gegeben wäre. Die Innenseite des Handlaufes 4 bzw. die Gleitlage wird durch die kleinen Zähne auf dem großen Durchmesser der Stützscheibe 10 kaum beschädigt. Der Antrieb des Handlaufes 4 erfolgt vergleichbar mit einem mehrstufigen Zahnradgetriebe, wobei der Handlauf 4 mit dem letzten Zahnrad im Eingriff ist. Ein am Tragwerk 27 angeordneter Befestigungswinkel 38 hält das Antriebsrad 23 in einem bestimmten Abstand zur Stützscheibe 10 fest, wobei der Abstand einstellbar ist. Fig. 10 shows the drive wheel 23 with a straight spur toothing 36, wherein the support plate 10 also has a spur toothing. The contact point 37 is located on the toothed wheel part circle and is form-fitting. The gears are equipped with many small teeth, because damage to the handrail 4 would be given by large teeth. The inner side of the handrail 4 or the sliding layer is hardly damaged by the small teeth on the large diameter of the support disk 10. The drive of the handrail 4 is comparable to a multi-stage gear transmission, wherein the handrail 4 with the last gear is engaged. An arranged on the structure 27 mounting bracket 38 holds the drive wheel 23 fixed at a certain distance from the support plate 10, wherein the distance is adjustable.
