Description

The The invention relates to a cleaning device for a preferably flat surface, in particular for a Window, with a cleaning strip and a arranged on it Cleaning cloth having cleaning device, wherein the cleaning strip aligned substantially parallel to the surface to be cleaned is.

A basically used for cleaning a flat glass surface cleaning device is in the DE 100 65 405 A1 described and has a cleaning element, which is covered with a trained example as a cleaning cloth cleaning medium and is offset by an eccentric drive in a parallel to the surface to be cleaned vibratory motion.

In order for such a cleaning device can be automatically held in contact with the surface to be cleaned, the cleaning device according to the WO 01/80703 A1 a device for generating negative pressure, so that the cleaning device can be guided along the surface to be cleaned with a substantially constant contact pressure. In order to make sure that in case of malfunction or the like, the cleaning device can not be detached from the surface to be cleaned and thus cause damage, describes the EP 1 237 456 B1 a safety device in which the distance of the cleaning device is monitored from the surface to be cleaned, if necessary to activate a holding device which prevents a crash of the cleaning device.

Since an autonomously operating cleaning device must be guided specifically to the surface to be cleaned, describes the patent application WO 2005/093536 A1 a surface processing system, in which for the navigation of the cleaning device, a fixed base part is provided, which allows by means of light and sound signals, a position determination of the provided with corresponding receiving units cleaning device. A similar device describes the WO 2005/093537 A1 , where the surface to be cleaned is subdivided into signal-codeable surface sections.

at a cleaning device in which by means of a mobile unit an autonomous cleaning of a surface, in particular a Window glass, done, is the available Absorption capacity of dirt usually in particular by the cleaning cloth is limited. To get as long as possible To ensure use of the cleaning device is It is therefore necessary to clean the cleaning cloth constantly or to renew at regular intervals or exchange. This means that the cleaning bar fitting cleaning cloth opposite the cleaning strip must be transported further, so a new, clean section of the cleaning cloth on the cleaning bar comes to the plant.

on the other hand must during cleaning the cleaning cloth firmly be fixed on the cleaning bar, so that the fast movements of the Cleaning bar can be transferred to the cloth.

Therefore must during the further transport of the cleaning cloth the fixation of the cloth on the cleaning bar temporarily To get picked up.

Of the Invention is based on the object, a cleaning device of the type mentioned above in such a way that on the one hand a ensures good fixation of the cleaning cloth on the cleaning strip is, on the other hand, in a simple way this fixation during the further transport of the cleaning cloth can be repealed.

These The object is achieved according to the invention in that fixing agent are provided, which is a sliding of the cleaning cloth on the cleaning strip prevent, and that for the further transport of the cleaning cloth to replace a soiled section of the cleaning cloth against a clean section, the fixative temporarily are solvable.

Of the The advantage achieved by the invention consists essentially in that the cloth is still for the fast eccentric Cleaning movement sufficiently well attached to the cleaning strip is. Due to the temporary solubility of the fixative The change of the cloth can be done automatically without any intervention of the device user are required. In this way Can the cloth capacity and thus the cleaning capacity be increased considerably.

In a preferred embodiment of the invention, the fixing means are arranged on the cleaning strip, wherein the cleaning strip arranged tiltable about its longitudinal axis and the cleaning cloth is held by at least one guide roller in the tensioned state. Due to the tiltable arrangement of the cleaning strip this can be easily detached from the cleaning cloth, so that the existing fixing come out of engagement with the cleaning cloth. It is advantageous if the cleaning strip is tiltable about its front bearing point, since in this way the cleaning strip can pivot into the interior of the cleaning device, so not vorbe in the cleaning surface in is moved, which would lead to an increase or decrease of the cleaning device and would require additional applied forces. Since the cleaning cloth is guided taut, this remains in its original level and can be transported by loosening the cleaning strip to a designated length on.

alternative However, there is also the possibility that the fixative are formed by an endless belt during the cleaning phase determined and freely movable during the cloth transport is, and its cleaning cloth side facing adhesive Owns property. As long as the endless belt is detected, takes it with the attached cloth in the context of cleaning movements with, whereas it during the further transport of the cleaning cloth through the fixing agent is taken until it after providing a fresh part of the cleaning cloth again found becomes.

The Endless band here is taut and can therefore also the Form cleaning strip.

alternative However, there is also the possibility that the endless band over the cleaning strip runs off and the cleaning cloth fitting part is supported on the cleaning strip.

The Fixing agents can also be formed by locking members be the cleaning cloth during the cleaning phase hold it tight and during the cloth transport give freely.

in the The invention will be described below with reference to a drawing Embodiment explained in more detail; show it:

1 a cleaning device with a cleaning strip in a merely schematic representation,

2 a training of the cleaning strip,

3 one of the 2 corresponding representation of an alternative embodiment.

The cleaning device shown in the drawing is intended for use preferably on a flat surface, in particular for a window or window glass, and has one of a cleaning strip 1 and a cleaning cloth arranged thereon 2 existing cleaning device on. The cleaning bar 1 is essentially parallel to the surface to be cleaned 3 aligned.

To achieve the longest autonomous operation of the cleaning device, the cleaning cloth must 2 be transported after reaching a certain degree of contamination. For this the cleaning cloth must 2 from the cleaning bar 1 be solved on which it is fixed during active cleaning, so that the rapid cleaning movements of the cleaning strip 1 on the cleaning cloth 2 be transmitted.

To the cleaning cloth 2 to replace a dirty section with a clean section temporarily from the cleaning bar 1 to solve, is the cleaning bar 1 according to a first embodiment according to 2 The cleaning cloth is arranged tiltable about its longitudinal axis 2 by at least one leadership role 4 is held in at least slightly tensioned state, thus the cloth 2 the tilting movement of the cleaning strip 1 does not follow. After further transport of the cleaning cloth 2 pivots the cleaning bar 1 back again, leaving the at the cleaning bar 1 arranged fixing 5 again in engagement with the cleaning cloth 2 come. These fixatives 5 can be designed in very different ways; conceivable, for example, a surface with high static friction or a surface structuring of suitable roughness up to a training similar to a hook and loop fastener.

The cleaning bar 1 is advantageously tiltable about its front bearing point, so that it pivots into the interior of the cleaning device, so not to increase the cleaning device relative to the surface to be cleaned 3 leads.

However, the fixing means according to the embodiment according to 3 also from one to roll 7 guided endless belt 6 be formed, which is detected during the cleaning phase, so no transport of the cleaning cloth 2 can be done. For transporting the cleaning cloth 2 becomes the endless band 6 Conversely, transferred to a floating state, so that the cleaning cloth 2 on the endless belt 6 can roll under its entrainment until the endless belt 6 is determined again.

Is this the endless belt 6 tight, so can the endless band 6 even the cleaning bar 1 form. Instead, however, according to 3b also the endless band 6 over the cleaning bar 1 drain off, leaving the cleaning cloth 2 fitting part of the endless band 6 at the cleaning bar 1 supported.

Finally, the fixatives 5 also be formed in the drawing not shown manner of locking members that the cleaning cloth 2 keep it tight during the cleaning phase and release it during the tissue transport ben.
