Abstract

An elongated suction nozzle (1) is provided which lies transversely to the operating direction. Arranged on the side of the suction nozzle mouth (3) facing away from the device is a comb-type lamella (4). The teeth (5) of this comb-type lamella (4) are intended to be pulled through the grooves of the surface to be cleaned. At least the teeth (5) consist of a rubber elastic material and the comb-type lamella (4) is arranged so as to be replaceable so that the device can be adapted to any groove pattern of the surface to be cleaned. In order to increase the suction power of the suction nozzle (1), a rubber elastic lamella (7) is likewise arranged on the side of the suction nozzle mouth (3) facing the device, which lamella can be provided with teeth or has no teeth. To improve the cleaning power, a blower nozzle (2) opens out in the operating direction before the suction nozzle (1), which blower nozzle blows or sprays compressed air or a cleaning agent under pressure against the surface to be cleaned. A protective wall (8) is arranged on each side of and with spacing from the blower nozzle (2). These protective walls extend in a V-shape towards the ends of the comb-type lamella (4). <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Reinigungsgerät für Rolltreppen und Rollbahnen, mit mindestens einer den Schmutz aufzusaugen bestimmten Saugdüse.The present invention relates to a cleaning device for escalators and taxiways, with at least one suction nozzle to suck up the dirt.

Bekannt ist zum Reinigen von Rolltreppen und Rollbahnen nur ein Trockenreinigungsapparat mit einer rotierenden Bürstenrolle und einer Staubsaugvorrichtung. Diesen Apparat stellt man an das obere Ende der laufenden Rolltreppe oder Rollbahn.For cleaning escalators and taxiways, only a dry cleaning device with a rotating brush roller and a vacuum cleaner is known. This device is placed at the top of the running escalator or runway.

Da die Reinigung jedoch durch diesen bekannten Apparat ungenügend ist, ziehen es viele Rolltreppenbesitzer vor, ihre Rolltreppen von Zeit zu Zeit demontieren und die demontierten Teile mit Pressluft reinigen zu lassen.However, since cleaning by this known apparatus is insufficient, many escalator owners prefer to dismantle their escalators from time to time and have the dismantled parts cleaned with compressed air.

Die Erfindung bezweckt ein handliches Reinigungsgerät zu schaffen, mittels welchem man Rolltreppen und Rollbahnen in kürzester Zeit optimal reinigen kann.The invention aims to provide a handy cleaning device by means of which escalators and taxiways can be optimally cleaned in the shortest possible time.

Während der kennzeichnende Teil des Patentanspruchs 1 der Erfindung entspricht, sollen die Merkmale der übrigen Patentansprüche den Erfindungsgegenstand in seiner Wirkung wesentlich verbessern.While the characterizing part of patent claim 1 corresponds to the invention, the features of the other patent claims are intended to substantially improve the effect of the object of the invention.

Dadurch dass die Zähne der kammartigen Lamelle 4 in die Rillen der Rolltreppen- bzw. Rollbahnoberfläche eindringen, wird der Ansaugbereich der Saugdüse zur Stirnseite des Gerätes hin annähernd luftdicht abgeschlossen, was die Saugkraft der Saugdüse erheblich erhöht und ein richtiges Reinigen erst ermöglicht. Eine herkömmliche Saugdüse kann auf den erwähnten gerillten Flächen keine genügende Saugkraft entwickeln.Due to the fact that the teeth of the comb-like lamella 4 penetrate into the grooves of the escalator or runway surface, the suction area of the suction nozzle towards the front side of the device is almost airtight, which considerably increases the suction power of the suction nozzle and enables proper cleaning. A conventional suction nozzle cannot develop sufficient suction power on the grooved surfaces mentioned.

Nachfolgend wird anhand der Zeichnung ein Ausführungsbeispiel des erfindungsgemässen Reinigungsgerätes beschrieben.

  • Figur 1 zeigt eine schematische Darstellung mit Sicht auf die Unterseite des Gerätes, und
  • Figur 2 zeigt die Ansicht auf die Stirnseite mit Saugdüse und kammartiger Lamelle.
An exemplary embodiment of the cleaning device according to the invention is described below with reference to the drawing.
  • Figure 1 shows a schematic representation with a view of the underside of the device, and
  • Figure 2 shows the view of the end face with suction nozzle and comb-like lamella.

Das Gerät ist hier mit einer Saugdüse 1 und einer Blasdüse 2 versehen. Die Mündung 3 der Saugdüse 1 weist eine längliche Form auf und liegt quer zur Arbeitsrichtung des Gerätes; ihre Saugkraft soll verhältnismässig stark sein. An der dem Gerät abgewendeten Seite der Saugdüsenmündung 3 ist eine kammartige Lamelle 4 mit Zähnen 5 angeordnet. Die Zähne 5 sind dazu bestimmt durch die Rillen der zu reinigenden Flächen gezogen zu werden. Die kammartige Lamelle 4 oder mindestens ihre Zähne 5 bestehen zweckmässig aus elastischem, vorzugsweise aus gummielastischem Material. Damit das Gerät den verschiedenen Rillenmustern der Rolltreppenflächen angepasst werden kann, ist die kammartige Lamelle 4 auswechselbar angeordnet. Die verschiedenen kammartigen Lamellen 4 können mit verschiedenbreiten und verschiedenlangen Zähnen 5 ausgeführt sein. Auch die Zwischenräume 6 zwischen den Zähnen 5 können verschieden gross sein. An der dem Gerät zugewendeten Seite der Saugdüsenmündung 3 ist ebenfalls eine kammartige Lamelle 4 oder eine zahnlose Lamelle 7 angeordnet, die ebenfalls wenigstens teilweise aus gummielastischem Material besteht.The device is provided here with a suction nozzle 1 and a blowing nozzle 2. The mouth 3 of the suction nozzle 1 has an elongated shape and is transverse to the working direction of the device; their suction power should be relatively strong. A comb-like lamella 4 with teeth 5 is arranged on the side of the suction nozzle mouth 3 facing away from the device. The teeth 5 are intended to be drawn through the grooves in the surfaces to be cleaned. The comb-like lamella 4 or at least its teeth 5 expediently consist of elastic, preferably of rubber-elastic material. So that the device matches the different groove patterns of the escalator surfaces can be adapted, the comb-like lamella 4 is arranged interchangeably. The various comb-like lamellae 4 can be designed with teeth 5 of different widths and lengths. The spaces 6 between the teeth 5 can also be of different sizes. Also arranged on the side of the suction nozzle mouth 3 facing the device is a comb-like lamella 4 or a toothless lamella 7, which likewise consists at least partially of rubber-elastic material.

In Arbeitsrichtung gesehen mündet vor der Saugdüse 1 die Blasdüse 2. Diese Balsdüse 2 soll unter einem Druck von 3 bis 5 atü ein Gas, z.B. Luft, gegen die zu reinigende Fläche blasen. Besser ist eine Flüssigkeit, z.B. ein Reinigungsmittel mit Druck auf die zu reinigende Fläche zu sprühen. Um zu vermeiden, dass Staub und/oder Reinigungsmittel zu weit aus dem Bereich der Saugdüse 1 weggeblasen wird, sind seitlich der Blasdüse 2 und mit Abstand davon je eine Schutzwand 8 vorgesehen. Diese Schutzwände 8 laufen V-förmig mit ihren freien Enden annähernd gegen die Enden der kammartigen Lamelle 4 zu. Ihre auf die zu reinigende Fläche aufzuliegen kommenden Kanten bestehen aus gummielastischem Material oder sind mit solchem überzogen, damit die zu reinigenden Flächen nicht zerkratzt werden. Im Bereich des Geräte-Haltegriffs 10 ist ein Blasdüsen-Betätigungshebel 11 angeordnet, mittels welchem die Blasdüse 2 durch Fingerdruck gegen den Druck einer Feder zu öffnen und bei Nachlassen des Fingerdrucks wieder zu schliessen ist. Die Saugdüse 1 ist mit einer Saugleitung 12 und die Blasdüse 2 mit einer Druckleitung 13 verbunden. Die kammartige Lamelle 4 ist an ihrer Aussenfläche mit mindestens einer Schutzlamelle 14 so abgedeckt, dass wenigstens der untere Teil der Zähne 5 frei bleibt. Auch diese Schutzlamelle kann aus gummielastischem Material bestehen. Sowohl die kammartige Lamelle 4 als auch die Schutzlamelle 14 mit einer Halterung 9 sind mittels Schrauben 15 auf der Saugdüse 1 befestigt.Viewed in the working direction, the blowing nozzle 2 opens in front of the suction nozzle 1. This baling nozzle 2 is intended to blow a gas, for example air, against the surface to be cleaned under a pressure of 3 to 5 atm. It is better to spray a liquid, for example a cleaning agent, with pressure onto the surface to be cleaned. In order to prevent dust and / or cleaning agents from being blown away too far from the area of the suction nozzle 1, a protective wall 8 is provided to the side of the blowing nozzle 2 and at a distance therefrom. These protective walls 8 run in a V-shape with their free ends approximately towards the ends of the comb-like lamella 4. Their edges coming to rest on the surface to be cleaned are made of rubber-elastic material or are covered with such material so that the surfaces to be cleaned are not scratched. A blower nozzle actuating lever 11 is arranged in the area of the device handle 10, by means of which the blower nozzle 2 can be opened by finger pressure against the pressure of a spring and closed again when the finger pressure is released. The suction nozzle 1 is connected to a suction line 12 and the blowing nozzle 2 to a pressure line 13. The comb-like lamella 4 is covered on its outer surface with at least one protective lamella 14 in such a way that at least the lower part of the teeth 5 remains free. This protective lamella can also consist of rubber-elastic material. Both the comb-like lamella 4 and the protective lamella 14 with a holder 9 are by means of Screws 15 attached to the suction nozzle 1.

Beim Reinigen wird das Gerät so über die zu reinigende Fläche gezogen, dass die Zähne der kammartigen Lamelle 4 in den Rillen der Fläche geführt sind. Dabei wird zuerst unter starkem Druck das Reinigungsmittel gegen die zu reinigende Fläche gesprüht und dann sofort der aufgelöste Schmutz mit starker Saugkraft abgesaugt. Die behandelte Rolltreppe ist nach dem Reinigen praktisch sofort trocken und kann ohne Wartezeit wieder begangen werden. Bei Verwendung eines geeigneten Reinigungsmittels bleiben die Metallteile der Rolltreppe korrosionsfrei und sehen wieder wie neu aus.When cleaning, the device is pulled over the surface to be cleaned so that the teeth of the comb-like lamella 4 are guided in the grooves of the surface. First, the cleaning agent is sprayed against the surface to be cleaned under strong pressure and then the dissolved dirt is immediately sucked off with strong suction. The treated escalator is almost immediately dry after cleaning and can be walked on again without waiting. When using a suitable cleaning agent, the metal parts of the escalator remain corrosion-free and look like new again.
