Definitions

  • the invention relates to a suction hood on wet floor cleaning machines for primarily commercial use; it is based on a device as described, for example, in US Pat. No. 4,817,233.
  • the object of the present invention is therefore to provide a construction or arrangement with respect to the suction hood which also enables the scrubbing roller to move fully towards the edges of the room and thus to completely clean such floor surfaces.
  • the scrubbing roller is mounted on a only one-end clamped, that is, on a so-called free arm axis b) the suction hood is axially displaceably mounted or guided relative to the scrubbing roller on the machine frame.
  • the suction hood can thus "retract" at the edges as far as possible with the brush roller at the edges up to the vertical right level of the free scrubbing roller end face and thus enable the edge surface in question to be cleaned with exact edges while maintaining the full suction effect.
  • Fig. 1 shows a floor cleaning machine schematically in side view
  • Fig. 2 is a view of the machine from below.
  • the floor cleaning machine X indicated purely schematically in FIG. 1, has in its front region a scrubbing roller 3 with an overlapping one Suction hood 2; the entire cleaning process with water supply, scrubbing and dry vacuuming is thus carried out in a manner known per se in the front area of the machine.
  • Combinatorically new here according to FIG. 2 is that the motor-driven scrubbing roller 3 rotates on a (free-arm) axis which is only clamped on one side within the suction hood 2 which covers it on both sides at the front side, this suction hood 2 leading axially displaceably relative to the scrubbing roller 3 is.
  • a (parallelogram) linkage 4, 5 with return spring 6 is used as a guide element for the axial displacement of the suction hood 2, linkage 4, 5 and return spring 6 on the machine bottom la are exposed or protected inside the housing.
  • any other form of linear guide of the suction hood 2 can be used and instead of the return spring 6 any other known type of alignment elements.

Description

Saughaube für Fußboden-Naßreinigungsmaschinen
Die Erfindung bezieht sich nach dem Oberbegriff des Pa¬ tentanspruchs 1 auf eine Saughaube an Fußboden-Naßrei- nigungsmaschinen für vornehmlich gewerblichen Einsatz; sie geht dabei aus von einem Gerat, wie es beispiels¬ weise in der US-PS 48 17 233 beschrieben ist.
ORIGINAL UNTERLAGEN Die Problematik bei allen bislang bekannten Maschinen dieser Gattung besteht bezüglich des Trockensaugens der zu bearbeitenden Bodenflachen vor allem dann, daß zur Erzielung der gewünschten Saugwirkung einerseits die Saughaube einen gewissen Überstand über die Enden der Scheuerwalze haben muß, was zum anderen wiederum den Nachteil mit sich bringt, daß man bei entsprechend großem Überstand zwangsläufig mit der Scheuerwalze nicht nahe genug an Ecken und Kanten heranfahren kann und dort somit Schmutzstreifen verbleiben.
Die vorliegende Erfindung hat sich daher die Aufgabe ge¬ stellt, eine Bauweise bzw. Anordnung bezüglich der Saug¬ haube zu treffen, die auch ein volles Heranfahren der Scheuerwalze an Raumkanten und somit eine vollkommene Reinigung solcher Bodenflachen ermöglicht.
Gelost wird diese Aufgabe dabei gemäß dem Patentanspruch 1 in überzeugend einfacher Weise durch das an sich kom¬ binatorische Zusammenwirken folgender zwei Baumerkmale:
a) Die Scheuerwalze ist auf einer lediglich einendig eingespannten, also auf einer sogenannten Freiarmachse gelagert und b) die Saughaube ist gegenüber der Scheuerwalze axialverschieblich am Maschinengestell gela¬ gert bzw. geführt.
Die Saughaube kann sich somit also beim Herausfahren mit der Bürstenwalze an Kanten maximal bis zur lot¬ rechten Ebene der freien Scheuerwalzen-Stirnflache "zurückziehen" und damit unter Beibehaltung der vollen Saugwirkung ein kantengenaues Reinigen der betreffenden Bodenfläche ermöglichen. Spezielle bauliche Ausgestal¬ tungsmerkmale dieser Erfindung sind noch in den Unter- anspruchen aufgeführt und zudem anhand einer Zeichnungs¬ skizze naher erläutert.
Es zeigen
Fig. 1 eine Fußbodenreinigungsmaschine schematisch dargestellt in Seiten¬ ansicht und
Fig. 2 eine Ansicht auf die Maschine von unten .
Die in Fig. 1 rein schematisch im Aufriß angedeutete Fußbodenreinigungsmaschine X besitzt in ihrem Frontbe¬ reich eine Scheuerwalze 3 mit diese übergreifender Saughaube 2; es wird also der gesamte ReinigungsVor¬ gang mit Wasserzufuhr, Scheuern und Trockensaugen in an sich bekannter Weise im Frontbereich der Maschine vollzogen. Kombinatorisch neu hierbei ist gemäß Fig.2 nun, daß die motorisch angetriebene Scheuerwalze 3 auf einer lediglich einseitig eingespannten ( Freiarm- ) Achse innerhalb der diese beidseits stirnseitig über¬ deckenden Saughaube 2 umläuft, wobei diese Saughaube 2 gegenüber der Scheuerwalze 3 axialverschieblich ge¬ führt ist.
In spezieller baulicher Ausgestaltung ist bei dem hier dargestellten Ausfuhrungsbeispiel dabei vorgesehen, daß als Führungselement für die Axialverschieblich- keit der Saughaube 2 ein ( Parallelogramm- ) Gestänge 4, 5 mit Rückstellfeder 6 dient, wobei Gestänge 4, 5 und Rückstellfeder 6 an der Maschinenuπterseite la freiliegend oder geschützt im Gehauseinneren angeordnet sind. Außerdem kann anstelle der zeichnerisch nur als Beispiel dargestellten Lösung, auch jede andere Form der Linearführung der Saughaube 2 Verwendung finden und anstelle der Rückstellfeder 6 jede andere bekannte Art von Ausrichtelementen.
