Abstract

With this safety device, the dangerous gap between the moving step (1) and the fixed base plate (10) provided on both sides of the step conveyor on which persons can step is covered by means of an elastic plastic lip (6; 7; 8; 9) fastened to the side edges of the step (1) of an escalator in the area of the tread surface (1.1) and the front end (1.2). The plastic lip (6; 7; 8; 9) is part of a plastic insert piece (2; 3; 4; 5) which can be screwed on in corresponding recesses on both sides of the body of the step (1) in the area of the horizontal tread surface (1.1) and in the area of the arched front end (1.2). It adapts itself to the base plate (10) if there are any inaccuracies in the same and has a very low coefficient of friction. The plastic lip (6; 7; 8; 9) is secured to the step (1) in such a way that the clearance space for the passage of the step (1) through a comb arranged at the top and bottom end of the travelling distance of the escalator only has to be increased to a minimum extent, and it can be screwed onto or unscrewed from the step (1) together with the insert piece (2; 3; 4; 5) at any time without the step (1) having to be dismantled from the step conveyor. <IMAGE>

Description

Die Erfindung betrifft eine Sicherheitseinrichtung zur Aufhebung des Spaltes zwischen der Trittfläche und dem Stirnteil einer bewegten Stufe und einer auf beiden Seiten längs des betretbaren Stufenbandes angeordneten stationären Sockelplatte einer Fahrtreppe.The invention relates to a safety device for eliminating the gap between the tread and the front part of a moving step and a stationary base plate of an escalator arranged on both sides along the step band that can be entered.

Es sind verschiedene Sicherheitseinrichtungen an den Stufen von Fahrtreppen bekannt, welche entweder durch farbliche Markierungen der Gefahrenzone der Seitenkanten der Stufentrittflächen, durch Aufsetzen von Schutzprofilen auf die äussersten seitlichen Kanten der Trittfläche, durch nach oben vorstehende seitliche Endrippen der Trittflächen, oder durch komplettes Abschliessen des Spielraumes zwischen den Seitenkanten der bewegten Stufen und den stationären Sockelplatten durch Kunststoffeinlagen die gleiche Aufgabe haben, Einklemmunfälle nach Möglichkeit zu vermeiden.Various safety devices on the steps of escalators are known, either by color-coding the danger zone on the side edges of the step treads, by placing protective profiles on the outermost side edges of the step surface, by protruding lateral end ribs of the step surfaces, or by completely closing off the play space between the side edges of the moving steps and the stationary base plates through plastic inserts have the same task of avoiding pinching accidents if possible.

Eine solche mit der US-PS 4,519,490 bekanntgewordene Sicherheitseinrichtung weist Kunststoffteile auf, welche auf der äussersten oder auf der zweiten seitlichen Rippe der Trittflächen der Stufen festgeklemmt sind und mit einem vorstehenden, am Sockelblech gleitenden Lappen den Spielraum zwischen jeder Stufe und dem Sockelblech abdecken und/oder durch einen seitlichen Einsatzkörper komplett schliessen. Es handelt sich dabei um einen Kunststoff mit geringem Reibwert gegenüber den Sockelplatten. Die auf die Rippen der Trittplatten aufgeklemmten Kunststoffteile benötigen im oberen und unteren horizontalen Laufbereich des Stufenbandes beim Durchlauf der Stufen durch die Kämme zusätzlich einen verhältnismässig grossen seitlichen Spielraum.Such a safety device, which has become known from US Pat. No. 4,519,490, has plastic parts which are clamped on the outermost or on the second lateral rib of the treads of the steps and cover the clearance between each step and the base plate with a protruding flap sliding on the base plate and / or close completely with a side insert body. It is a plastic with a low coefficient of friction compared to the base plates. The plastic parts clamped onto the ribs of the tread plates additionally require a relatively large lateral play in the upper and lower horizontal running area of the step belt when the steps pass through the combs.

Ein Nachteil dieser Einrichtung liegt darin, dass die geklemmten Kunststoffteile in der Fahrtrichtung der Stufen verschoben oder gar aus der geklemmten Halterung herausgerissen werden können. Zu dem bei fehlendem oder verschobenem Kunststoffteil vergrösserten seitlichen Spielraum mit gesteigerter Einklemmgefahr kommt dann die erhöhte Einklemmgefahr im Bereich des Einlaufes der Stufe in den Kamm durch den vergrösserten seitlichen Durchlaufspielraum.A disadvantage of this device is that the clamped plastic parts in the direction of travel of the steps can be moved or even torn out of the clamped bracket. In addition to the increased lateral clearance with increased risk of pinching in the absence or displaced plastic part, there is then the increased risk of pinching in the area of the step's entry into the comb due to the increased lateral clearance.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine auf beiden Seiten der Stufen angeordnete Schutzvorrichtung vorzuschlagen, welche fest und unverrückbar mit der Stufe verbunden ist und im Bereich des Stufeneinlaufes in den Kamm keine wesentliche Vergrösserung der Einlaufspielräume erfordert.The present invention is based on the object of proposing a protective device arranged on both sides of the steps, which is firmly and immovably connected to the step and does not require a substantial increase in the inlet clearance in the area of the step entry into the comb.

Diese Aufgabe wird durch die im ersten Anspruch gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in the first claim.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Kunststofflippe fest und unverschiebbar mit der Stufe verbunden ist, und dass die an der Aussenseite der äussersten Rippe eines Einsatzstückes befestigte Kunststofflippe keine der äusseren Rippen umgreift und die äusserste Rippe seitlich nur minim überragt, so dass die Spielräume für den Durchlauf der Stufe durch den am oberen und am unteren Ende der betretbaren Förderstrecke angeordneten Kamm, im Bereich der linken und der rechten Sockelplatte, nur sehr wenig vergrössert werden müssen. Ein weiterer Vorteil liegt auch darin, dass eine in Betrieb befindliche Kunststofflippe bei einer eventuellen Beschädigung sehr einfach, auch durch Nichtfachleute, an Ort und Stelle austauschbar ist, indem sie zusammen mit dem zugehörigen Einsatzstück abschraubbar und durch ein neues Einsatzstück mit einer zugehörigen sicher befestigten Kunststofflippe an der Stufe wieder anschraubbar ist, ohne dass die Stufe dazu aus dem Stufenband ausgebaut werden muss.The advantages achieved by the invention can be seen essentially in the fact that the plastic lip is firmly and immovably connected to the step, and that the plastic lip attached to the outside of the outermost rib of an insert piece does not engage around any of the outer ribs and the outermost rib only minimally on the side towered over, so that the scope for the passage of the step through the comb arranged at the upper and lower ends of the accessible conveyor section, in the area of the left and the right base plate, need only be increased very little. Another advantage is that a plastic lip in operation is very easy to replace on site if damaged, even by non-specialists, by unscrewing it together with the associated insert and with a new insert with an associated securely attached plastic lip can be screwed onto the step again without the step having to be removed from the step belt.

Die vorstehend beschriebene Sicherheitseinrichtung wird bei Fahrtreppen mit einem in einem Tragkörper endlos umlaufenden Stufenband eingebaut. Das endlos umlaufende Stufenband weist eine grössere Anzahl Stufen 1, vorzugsweise in Aluminiumpressguss auf, welche auf beiden Seiten mit je einer endlosen Stufenkette gelenkig verbunden sind. Das Stufenband ist über obere Antriebskettenräder und untere Umlenkkettenräder umgelenkt und weist einen betretbaren Vorlauf mit einem unteren und einem oberen horizontalen und einem schrägen Laufbereich und einen im Tragkörper verdeckt angeordneten Rücklauf auf. Der Vorlauf des Stufenbandes ist zwischen zwei seitlichen Handlauf-Balustraden angeordnet und beidseits mit minimalem Spielraum an festen Sockelplatten 10 vorbeigeführt. Diese Spielräume bedeuten vor allem bei den Übergängen des Stufenbandes von den horizontalen zum schrägen Laufbereich und umgekehrt, dort wo jede einzelne Stufe zur Bildung einer erhöhten Trittfläche 1.1 oder des horizontalen Laufbereiches Relativbewegungen ausführt, eine latente Einklemmgefahr für Kleidungsstücke oder Körperteile der Fahrgäste. Diese Spielräume werden durch die erfindungsgemässe Einrichtung mit den Kunststofflippen 6; 7; 8; 9 abgedeckt. Die als Teil von anschraubbaren Einsatzstücken 2; 3; 4; 5 in entsprechenden Aussparungen fest und sicher mit der beweglichen Stufe 1 verbundenen Kunststofflippen 6; 7; 8; 9 liegen an den stationären Sockelplatten 10 elastisch an. Sie weisen einen sehr geringen Reibungskoeffizienten und eine gewisse Elastizität auf, die es erlaubt, leichte Ungenauigkeiten der Sockelplatten 10 zu überbrücken und den Spalt zwischen den Stufen 1 und den Sockelplatten 10 jederzeit abzudecken und die Einklemmgefahr praktisch auszuschliessen. Die Kunststofflippe 6; 7; 8; 9 ist an den Einsatzstücken 2; 3; 4; 5 so befestigt, dass sie keine der äusseren Rippen der Einsatzstücke 2; 3; 4; 5 umgreift und die äusserste Rippe seitlich nur minim überragt, dass für den Durchlauf der Stufe 1 durch einen beim Übergang vom betretbaren Vorlauf zum abgedeckten Rücklauf des Stufenbandes angeordneten Kamm 12 nur ein minimal vergrösserter seitlicher Spielraum 12.1 erforderlich ist. Die Kunststofflippe 6; 7; 8; 9 kann jederzeit zusammen mit dem Einsatzstück 2; 3; 4; 5 an der Stufe 1 an- oder abgeschraubt werden, ohne dass die Stufe 1 selbst aus dem Stufenband ausgebaut werden muss.The safety device described above is installed in escalators with an endlessly extending step belt in a supporting body. The endless revolving step belt has a larger number of steps 1, preferably in die-cast aluminum, which are articulated on both sides with an endless step chain. The step belt is deflected via upper drive sprockets and lower deflecting sprockets and has an accessible lead with a lower and an upper horizontal and an inclined running area and a return arranged concealed in the supporting body. The lead of the step belt is arranged between two side handrail balustrades and is guided past fixed base plates 10 on both sides with minimal scope. These margins mean above all in the transitions of the step belt from the horizontal to the inclined running area and vice versa, where each individual step to form an elevated step surface 1.1 or the horizontal Running area executes relative movements, a latent risk of pinching clothes or body parts of the passengers. These margins are made possible by the device according to the invention with the plastic lips 6; 7; 8th; 9 covered. The as part of screw-on inserts 2; 3; 4; 5 in corresponding recesses firmly and securely connected to the movable step 1 plastic lips 6; 7; 8th; 9 rests on the stationary base plates 10 elastically. They have a very low coefficient of friction and a certain elasticity, which makes it possible to bridge slight inaccuracies in the base plates 10 and to cover the gap between the steps 1 and the base plates 10 at any time and to practically exclude the risk of pinching. The plastic lip 6; 7; 8th; 9 is on the inserts 2; 3; 4; 5 fastened so that they do not have any of the outer ribs of the insert pieces 2; 3; 4; 5 encompasses and the outer rib projects only minimally beyond the side, so that only a minimally increased lateral clearance 12.1 is required for the passage of stage 1 due to a comb 12 arranged during the transition from the accessible feed to the covered return of the step belt. The plastic lip 6; 7; 8th; 9 can at any time together with the insert 2; 3; 4; 5 can be screwed or unscrewed from level 1 without having to remove level 1 from the step belt itself.

Die Erfindung beschränkt sich nicht auf das dargestellte Ausführungsbeispiel. Es liegt im Rahmen der Erfindung, beispielsweise auch Fahrtreppen mit sockellosen Balustraden mit der Sicherheitseinrichtung auszurüsten, wobei die Kunststofflippen statt an Sockelplatten direkt an senkrecht angeordneten Balustradenplatten gleitend anliegen und so den Spalt zwischen der Stufe und den Balustradenplatten abdeckt.The invention is not limited to the illustrated embodiment. It is within the scope of the invention, for example, to equip escalators with base-less balustrades with the safety device, the plastic lips instead of on base plates directly sliding against vertically arranged balustrade panels and thus covering the gap between the step and the balustrade panels.
