Description

Sicherheitseinrichtung an der Einlaufstelle eines umlaufenden Handlaufs einer Rolltreppe, eines Rollsteiges oder dgl . Safety device at the entry point of a revolving handrail of an escalator, a moving walk or the like.
Die Erfindung betrifft eine Sicherheitseinrichtung an der Einlaufstelle eines umlaufenden Handlaufs einer Rolltreppe, eines Rollsteigs oder dgl. in eine feststehende Brüstung.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.
Rolltreppen und Rollsteige besitzen im Bereich der Einlaufstelle des umlaufenden Handlaufs eine Sicherheitseinrichtung, da sich gezeigt hat, daß auf einer Fahrtreppe fahrende Personen, insbesondere Kinder, sich hin und wieder so lange an dem Handlauf festhalten, bis ihre Hand zu der Einlaufstelle des Handlaufs in die feststehende Brüstung gelangt. In einem solchen Fall kann es vorkommen, daß die Finger in den Spalt hinein¬ gezogen werden, der sich zwischen der Oberfläche des Handlaufs und der Einlauföffnung in der Brüstung befindet. Ohne besondere Sicherheitsma߬ nahmen besteht also die Gefahr erheblicher Verletzungen.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.
Zur Vermeidung derartiger Verletzungen wird in der DE-PS 20 54 640 eine Sicherheitsvorrichtung vorgeschlagen, welche über mehrere an der Einlauf¬ stelle schwenkbar angeordnete, nach Art von Klappen gestaltete Platten verfügt. Wird von einer Person der Handlauf auch noch im Bereich der Einlaufstelle festgehalten, führt die Berührung der Finger mit den Plat¬ ten zu deren Verschwenken, wodurch der Kontakt eines Sicherheitsschalters zum Stillsetzen der Rolltreppe betätigt wird. Um eine mutwillige Fehlaus¬ lösung der Sicherheitseinrichtung durch eine ungewollte Betätigung der Platten zu vermeiden, ist bei der bekannten Sicherheitseinrichtung ferner vorgesehen, jeweils zwei in geringem Abstand hintereinander angeordnete, schwenkbare Platten zu verwenden. Hierbei ist der Abstand zwischen dem Handlauf und dem Innenrand der ersten Platte so groß bemessen, daß Finger ohne Verletzungen in diesen Spalt hineingelangen können. Erst bei Berüh¬ rung mit einer der beiden hinteren Platten wird der gemeinsame Sicher¬ heitsschalter betätigt und zugleich die noch geschlossene erste Platte entriegelt. Diese bekannte Sicherheitseinrichtung wird zwar hohen Anfor¬ derungen hinsichtlich Sicherheit und Schutz gegen Fehlauslösungen ge¬ recht, sie ist jedoch aus einer Vielzahl von Teilen aufwendig zusammenge-In order to avoid such 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. In order to avoid a deliberate false triggering of the safety device by an undesired actuation of the plates, the known safety device also provides for the use of two pivotable plates arranged one behind the other at a short distance. Here, 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. Only when one of the two rear plates is touched is the common safety switch actuated and at the same time the first plate, which is still closed, is unlocked. This known safety device is indeed high Anfor¬ requirements regarding safety and security against false triggering ge ¬ right, it is, however zusammenge- from a variety of parts complicated
ERSATZBLATT setzt. Zur Übertragung der Schwenkbewegung der Platten auf den Kontakt des Sicherheitsschalters ist ein mit einer Auflaufkante versehenes Betä¬ tigungsmittel erforderlich, dessen Justierung einerseits zu sämtlichen Platten und andererseits zu dem Kontakt des Sicherheitsschalters sehr exakt vorgenommen werden muß, um die angestrebte Funktion zu gewährlei¬ sten. Bereits geringe Abweichungen von den vorgesehenen Einstellungen können dazu führen, daß die vordere Platte zu spät entriegelt wird, wo¬ durch Verletzungen auftreten können.REPLACEMENT LEAF puts. To transmit the pivoting movement of the plates to the contact of the safety switch, an actuating means provided with a leading edge is required, the adjustment of which must be made very precisely on the one hand to all the plates and on the other hand to the contact of the safety switch in order to guarantee the desired function. Even slight deviations from the intended settings can lead to the front plate being unlocked too late, which can result in injuries.
Ziel des Erfindungsgegenstandes ist die Schaffung einer Sicherheitsein¬ richtung zum Notstopp des Antriebes bei Eintreten von Gegenständen (Fin¬ gern oder ähnlichen) in den Handlaufeinlauf, wobei die Abschaltung auch bei gerissenem oder ungespanntem Handlauf erfolgen soll. Die Sicherheits¬ einrichtung soll einfach aufgebaut und leicht zugänglich sein.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.
Dieses Ziel wird erreicht durch ein elastisch verformbares Handlaufein- laufteil, in dessen rückwärtigem Bereich ein über Verbindungselemente die Verformung des Handlaufeinlaufteiles auf einen Endschalter übertragendes stangenförmig ausgebildetes Element gelagert ist.This goal is achieved by an elastically deformable handrail inlet part, in the rear area of which is mounted a rod-shaped element which transmits the deformation of the handrail inlet part to a limit switch via connecting elements.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteran¬ sprüchen zu entnehmen.Advantageous developments of the subject matter of the invention can be found in the subclaims.
Infolge der Elastizität des Handlaufeinlaufes in Verbindung mit der eine Stauchung des elastischen Teiles in eine Längsbewegung umwandelnden Stan¬ ge kann der nachgeschaltete Endschalter bereits so rechtzeitig betätigt werden, daß eine Gefahr für Personen weitestgehend ausgeschlossen werden kann. Gleiches gilt für bewußt oder unbewußt in den Handlaufeinlauf ein¬ dringende Gegenstände, die u.U. zu einer Beschädigung von Rolltreppenbau¬ teilen führen können. Um eine verzögerte Ansprechzeit der Sicherheitsein¬ richtung mit einfachen Mitteln vorzusehen, wird der Bewegungsablauf der Stange durch eine mechanisch vorspannbare Vorspanneinrichtung beeinflußt. Dies bedeutet, daß erst bei einem vorgegebenen auf den elastischen Be¬ reich des Handlaufeinlaufes wirkende Kraft der Endschalter betätigt wird. Durch diese Maßnahme kann sichergestellt werden, daß die Rolltreppe bzw.As a result of the elasticity of the handrail inlet in connection with the rod converting a compression of the elastic part into a longitudinal movement, the downstream limit switch can be actuated in time so that a danger to persons can be largely excluded. The same applies to consciously or unconsciously penetrating objects into the handrail inlet, which may can lead to damage to escalator components. In order to provide a delayed response time of the safety device with simple means, 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

Die Sicherheitseinrichtung ist einfach aufgebaut und leicht zugänglich, wobei die mechanische Vorspannung der Vorspanneinrichtung problemlos ein- bzw. nachgestellt werden kann.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.

Die Sicherheitseinrichtung 1 ist im Bereich einer Endplatte 2 einer nicht weiter dargestellten Rolltreppenbrüstung vorgesehen. Lediglich angedeutet ist die Balustrade 3 in Form einer Glasscheibe. Im Bereich der Endplatte 2 ist eine Ausnehmung 4 vorgesehen, die zur Aufnahme eines Handlaufein- laufteiles 5 dient. Das Handlaufeinlaufteil 5 ist im Bereich der Einlauf¬ stelle 6 für den hier lediglich angedeuteten Handlauf 7 mit einem elasti¬ schen Balgen 8 versehen, der in seinem rückwärtigen Bereich mit einem abgewinkelten Bauteil 9 versehen ist. Über eine Zwischenplatte 10 als Verbindungselement wird mit dem freien Schenkel 11 des Bauteiles 9 eine Stange 12 verbunden, die in ihrem freien Endbereich eine Schaltkulisse 13 aufweist, die wiederum mit einer konisch sich verjüngenden Ausnehmung 14 ausgebildet ist, deren Spitze 15 auf dem Stößel 16 eines Endschalters 17 ruht. Die Stange 12 ist im wesentlichen vertikal angeordnet und gegenüber der Endplatte 2 über weitere Verbindungselemente 18 geführt, die wiederum mit der Endplatte 2 verschraubt sind. Die weiteren Verbindungselemente 18 beinhalten eine Führung 19, die zur Aufnahme eines Gummifederelementes 20 vorgesehen ist. Das Gummifedere!ement 20 wird von einer seitlichen 21 sowie einer unteren Begrenzungswand 22 umgeben, wobei von oben eine napfförmige Platte 23 auf der Gummifeder 20 aufliegt. Unterhalb des Bo¬ dens 22 ist eine weitere Gummifeder 24 vorgesehen, deren eine StirnseiteThe 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. In the area of the end plate 2, 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. Via an intermediate plate 10 as a connecting element, 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
