Description

Die Erfindung bezieht sich auf ein Reinigungsgerät zum Rei­nigen einer laufenden Rolltreppe. Das Reinigen einer Roll­treppe geschah bisher meist von Hand. Dies ist mit einem erheblichen Zeitaufwand verbunden. Zwar sind die meisten Rolltreppen bereits an den verdeckten Umlenkstellen mit ei­nem Auffangbehälter verbunden, in den aber nur die Lose auf den Stufen liegenden Schmutzpartikel und Staub fallen. Moderne Rolltreppen sind heutzutage meist mit senkrecht zur Breite der Standfläche verlaufenden Rillen versehen, in denen sich leicht Schmutz absetzt, der nicht von selber an den Umlenkstellen aus den Rillen fällt.The invention relates to a cleaning device for cleaning a running escalator. Up to now, cleaning an escalator has mostly been done by hand. This takes a considerable amount of time. Most escalators are already connected to a collection container at the hidden deflection points, but only the loose particles and dust lying on the steps fall into them. Nowadays, modern escalators are usually provided with grooves that run perpendicular to the width of the standing surface, in which dirt easily settles that does not fall out of the grooves at the deflection points.

Wenn hier und auch in der nachfolgenden Beschreibung von einer Rolltreppe mit Stufen die Rede ist, ist damit auch eine laufende Rampe oder ein laufender Steg gemeint. Der Aufbau der Rampe oder des Steges entspricht nämlich demje­nigen der Treppe, indem hier nur jene die einzelnen Stufen ausmachenden Elemente anders ausgebildet sind, entlang weniger steil oder horizontal angeordneten Schienen geführt sind und an den Enden wie bei der Rolltreppe umgelenkt wer­ den.If an escalator with steps is mentioned here and also in the description below, this also means a running ramp or a running footbridge. The structure of the ramp or the bridge corresponds to that of the stairs, in that only those elements that make up the individual steps are designed differently, are guided along less steep or horizontally arranged rails and are redirected at the ends as in the escalator the.

In neuster Zeit sind zur Reinigung der Stufen solcher Rolltreppen Geräte bekannt geworden, die mit rotierenden Bürsten arbeiten, sowie staubsaugerähnliche Geräte, die mit breiten Saugdüsen arbeiten.In recent times, devices that work with rotating brushes, as well as vacuum cleaner-like devices that work with wide suction nozzles, have become known for cleaning the steps of such escalators.

Die Erfindung hat sich zur Aufgabe gestellt, ein einfaches und billiges Gerät zu schaffen, das von der Fortbewegung der Treppe selber Gebrauch macht und somit ohne Fremd­energie auskommen kann. Voraussetzung dazu ist, dass die Treppe sich bewegt.The invention has set itself the task of creating a simple and inexpensive device that makes use of the movement of the stairs themselves and can therefore do without external energy. The prerequisite for this is that the stairs move.

In der beigefügten Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.In the accompanying drawing an embodiment of the subject of the invention is shown.

Es zeigt:

  • Fig. 1 Das Reinigungsgerät in Betriebslage in Ansicht von oben;
  • Fig. 2 dasselbe Gerät, ebenfalls in Betriebslage in Seiten­ansicht und;
  • Fig. 3 dasselbe Gerät in Transportstellung.
It shows:
  • Figure 1 The cleaning device in the operating position in a view from above.
  • Figure 2 shows the same device, also in the operating position in side view and.
  • Fig. 3 shows the same device in the transport position.

Das in den Figuren 1-3 dargestellte Gerät hat einen Rahmen der aus einer massiven Platte 1, mit einem daran ange­schweissten Arm 2 in Form eines Vierkantrohres besteht. Vorne an der Platte 1 ist eine Achse 3 befestigt, die an ihren Enden mit Transportrollen 31 versehen ist.The device shown in Figures 1-3 has a frame which consists of a solid plate 1 with an arm 2 welded to it in the form of a square tube. An axis 3 is attached to the front of the plate 1 and is provided with transport rollers 31 at its ends.

Unter der Platte 1 ist eine U-förmige Aufnahme 11 für eine Bürste 4 befestigt. Anschliessend an und in Betriebslage hinter der Aufnahme 11 ist ein Staub-Absaugkanal 12 ange­bracht, der mit einem Anschlussrohr 13 für einen Staubsau­gerschlauch versehen ist. Wenn hier von "oben" und "unten" oder "hinter" die Rede ist, bezieht sich dies auf die Be­triebslage der Reinigungsvorrichtung wie sie in den Figuren 1 und 2 dargestellt ist.Under the plate 1, a U-shaped receptacle 11 for a brush 4 is attached. Connected to and in the operating position behind the receptacle 11 is a dust suction channel 12, which is provided with a connection pipe 13 for a vacuum cleaner hose. If "above" and "below" or "behind" is mentioned here, this refers to the operating position of the cleaning device as shown in FIGS. 1 and 2.

In der in Figur 3 dargestellten Transportlage ist nämlich das ganze Gerät um etwa 135° um die Rollen 31 geschwenkt und liegt beispielsweise die Bürste 4 nicht mehr unter der Platte 1, sondern oben auf derselben!In the transport position shown in Figure 3, the entire device is pivoted about 135 ° about the rollers 31 and, for example, the brush 4 is no longer under the plate 1, but on top of it!

Oben auf (in Betriebslage) der Platte 1 ist ein V-förmig gebogener Flacheisenbügel 5 angeschweisst, der eine selbst­einstellende Transportrolle 51 trägt.A V-shaped flat iron bracket 5 is welded onto the top (in the operating position) of the plate 1 and carries a self-adjusting transport roller 51.

Die eigentliche Reinigungsbürste 4 ist in der Aufnahme 11 gehalten und mittels zwei Flügelmuttern 41 befestigt, sodass sie durch Lösen der Muttern leicht wegnehmbar und auswechselbar ist. Die Bürste wird später noch im Detail beschrieben.The actual cleaning brush 4 is held in the receptacle 11 and fastened by means of two wing nuts 41, so that it can be easily removed and replaced by loosening the nuts. The brush will be described in detail later.

Der Arm 2 ist mit drei Bohrungen versehen, die mit kurzen Rohrabschnitten 21 ausgekleidet sind. Diese Rohrabschnitte sind fest mit dem Arm verbunden. Sie liegen etwa in der Ebene der Platte 1 und verlaufen senkrecht zum Arm 2. Der in Figur 1 äusserste Rohrabschnitt ist beidseitig ge­schützt. Dieser Schutz 22 dient beim Transport als Griff. An der Unterseite des Armes ist ein Zapfen 23 angebracht der für eine etwa horizontale Betriebslage des Gerätes sorgt.The arm 2 is provided with three bores, which are lined with short pipe sections 21. These pipe sections are firmly attached to the arm. They lie approximately in the plane of the plate 1 and run perpendicular to the arm 2. The outermost tube section in FIG. 1 is protected on both sides. This protection 22 serves as a handle during transport. On the underside of the arm a pin 23 is attached which ensures an approximately horizontal operating position of the device.

Oben auf dem Arm 2 etwa oberhalb des Zapfens 23 ist eine Halteklammer 24 angebracht.A holding clamp 24 is attached to the top of the arm 2 approximately above the pin 23.

Die bereits erwähnte Bürste 4 besitzt eine Hälfte harter Borsten 42, die den Schmutz lösen und eine zweite Reihe von weicheren Borsten, die den gelösten Schmutz und Staub zu­sammenfegen, der dann zum Schlusss vom Absaugkanal abge­saugt werden kann. die harten Borsten können beispielsweise aus rostfreiem Stahl- und die weicheren aus Nylon bestehen. In den Figuren 1 und 2 ist das Reinigungsgerät in Betriebs­lage auf einer Rolltreppe dargestellt. In diesen Figuren sind die Wangen der Treppe mit W angedeutet auf denen der Handlauf H sich synchron mit der Treppe bewegt. U ist ein fester, nicht mitbewegender Uebergangsteil zur Treppe unter dem sich die Stufen S₁-S₃ hervorschieben. Während des Rei­nigungsvorganges sollte die Treppe, laufen. Das Reini­gungsgerät wird während des Betriebes durch einen Stab 6 der durch eines der Rohrabschnitte 21 gesteckt ist, gehalten. Der Stab 6 stützt sich beidseitig am Kopf eines festen Teiles der Treppenwangen W ab. Der Stab besteht aus teleskopisch ineinander schiebbaren Teilen, damit seine Länge der Breite der Treppe angepasst werden kann.The brush 4 already mentioned has a half of hard bristles 42 which loosen the dirt and a second row of softer bristles which sweep up the loosened dirt and dust, which can then finally be sucked off from the suction channel. the hard bristles can be made of stainless steel, for example, and the softer ones of nylon. In Figures 1 and 2, the cleaning device is shown in the operating position on an escalator. In these figures, the cheeks of the stairs are indicated by W on which the handrail H moves synchronously with the stairs. U is a fixed, non-moving transition part to the stairs under which the steps S₁-S₃ slide out. The stairs should run during the cleaning process. The cleaning device is during operation by a rod 6 which is inserted through one of the pipe sections 21, held. The rod 6 is supported on both sides of the head of a fixed part of the stair stringers W. The bar consists of telescopically slidable parts so that its length can be adjusted to the width of the stairs.

Die Reinigung geht kontinuierlich vor sich. Die Bürste 4 hat die Stufe S₃ gereinigt und liegt nun auf der Stufe S₂ auf. Es ist klar, dass man die ganze Treppe auf diese Weise reinigen kann, aber auch, dass man bei starker Verschmut­zung die ganze Treppenlänge auch mehrmals an der Reini­gungsvorrichtung entlang führen kann.The cleaning is ongoing. The brush 4 has cleaned the level S₃ and is now on the level S₂. It is clear that the entire staircase can be cleaned in this way, but also that the entire length of the staircase can be run several times along the cleaning device if it is very dirty.

Die Figur 3 zeigt schliesslich die Lage des Reinigungs­gerätes beim Transport. Das Gerät ruht auf den drei Rollen 31, 51 und kann leicht zur Reinigungsstelle hingefahren oder von derselben weggefahren werden. Der oberste Rohrabschnitt 21 dient dabei als Griff und die selbstein­stellende Rolle 51 erlaubt ein leichtes Manövrieren. Der Stab 6 ist nun ganz zusammengeschoben und ist in der Halte­klemme 24 gehalten. Das andere Ende des Stabes ist durch eine im Bügel 5 vorgesehene Bohrung 52 gesteckt.Finally, FIG. 3 shows the position of the cleaning device during transport. The device rests on the three rollers 31, 51 and can easily be moved to or removed from the cleaning point. The uppermost pipe section 21 serves as a handle and the self-adjusting roller 51 allows easy maneuvering. The rod 6 is now completely pushed together and is held in the holding clamp 24. The other end of the rod is inserted through a bore 52 provided in the bracket 5.

Nach einem Reinigungvorgang wird die Bürste 4 durch Lösen der Flügelmuttern 41 aus der Aufnahme 11 herausgenommen und gereinigt. Meist genügt dazu ein Schwenken der Borsten in einer Reinigungsflüssigkeit.After a cleaning process, the brush 4 is removed from the receptacle 11 by loosening the wing nuts 41 and cleaned. A swiveling of the bristles in a cleaning liquid is usually sufficient.
