Cleaning device for cleaning floors or the like.

The invention relates to a cleaning device for cleaning Floors or the like with a frame, a base plate and a handle for operation.

There are already numerous cleaning devices known that about the floor surface to be cleaned is moved and the means on its underside for picking up dirt and / or for applying it of cleaning agents. If, for example, dirt is to be picked up, this is usually done by means of a rag located on the underside of the cleaning device, the rag optionally with a cleaning agent is also soaked. Often, however, this already has to be done after a short time cleaned again or with a new cloth be replaced, namely when the cloth is so filled with dirt that it no longer absorb any more dirt can. To apply a care product to the floor surface, a different cloth is usually required, which is included with the is soaked in a care product. In order to achieve an even distribution of the same, relatively often smaller ones have to be used Put amounts on the cloth. Most cleaning devices have a long handle as a handle, which enables the Carry out cleaning of the floor surface in an upright position. However, it is always cumbersome when the cleaning process repeatedly interrupted to clean or replace the cloth or to add a cleaning or care agent must become. It is also disadvantageous that one

but usually has to stoop for this.

The invention has the task of creating a cleaning device in which a replacement or cleaning of a cloth or the like is no longer necessary at least during a uniform cleaning process and in the case of clogging of cleaning or care products an interruption of the Cleaning process is not necessary. It should also be avoided that one has to bend down to do this. Incidentally, it belongs to the object of the invention to eliminate the difficulties and disadvantages of the prior art.

For a cleaning device of the type mentioned with a frame, a base plate and a handle for operation, it is therefore proposed according to the invention to solve this problem that a material web, fabric or the like is guided over the underside of the base plate, which is arranged on the frame Storage location is transported to a further storage location, vta that a manually operable drive device is provided for transporting the material web from one storage location to the other.

Such a cleaning device enables a much longer cleaning process without the same being interrupted is required. The drive device for the material web can be actuated at certain time intervals, wherein this is then transported further by such a distance that the used part has been removed and there is now a clean part under the base plate. The material web can consist of paper, cloth or plastic film. Also is the addition of cleaning agents in an advantageous manner, for example, possible in such a way that at least one container for a PurigngsflUssigkeit is provided, the outlet line over a valve in the area of the material web to wet the

same is performed. So you also need to add Cleaning or care products not to interrupt the cleaning process itself, because the valve is easy to pass through Use appropriate training of its operating handle in an upright position. You can even use two containers be provided with different cleaning fluids, wherein the valve is then designed as a switch valve that the removal from one or the other container is permitted.

The cleaning device according to the invention is advantageously designed so that a rotatable core is arranged in each case at a storage location and that the material web is in the form of a roll is transported from one core via the underside of the base plate to the other core.

the inner pipe section 74 is firmly connected to the transverse part 72, while the outer circular section 76 can slide on the inner pipe section 74. As shown in Figure 5, the pipe sections 74 and 76 merge into handles 78 and 80, respectively. As can be seen from FIG. 4, the two Bowden cables 4o are guided along the side parts 68 and 69 of the handle holder 66 from each pawl arrangement J> 6 and then connected to one another in the middle. The outer shell of this connected part of the Bowden cables 4o is fastened to the transverse part 72, while the inner pulling cable 48 passes through the transverse part 72 and runs upwards, where it is fastened to the pipe section 76.

A recess is provided in the middle of the cleaning device, which leads down from the lid 12 and is arranged in the two containers 82 and 84 with removable caps are. As can be seen from Figure 2, a line 86 leads from the bottom of the container 82 to a switch valve 88, and a Similar line, not shown, leads from the bottom of the Container 84 also to the switching valve 88. This has a Conventional outlet line 90 leading to a manifold 92 which extends over the entire width of the cleaning device extends and over a number of across the base plate 6 and lies through these openings. The switching valve 88 is operated by a lever 94, which extends through a slot 96 in the cover 12 of the cleaning device to the top extends towards (Fig. 3). When see the lever. 94 in its middle Position is, the switching valve 88 is closed. If the lever 94 is moved to one side, it opens the changeover valve 88 so that from one of the containers 82 or 84 cleaning liquid into the outlet line 90 and from there to Base plate 6 can flow; the lever 94 moves to the other side moved towards, then cleaning liquid flows out of the other container in the same way. By the amount of movement

009808/0317

of the lever 9k in the lateral direction, the amount of cleaning liquid can be specified.

On the underside of the base plate 6 are two foam rubber pads 93 and loo attached, with a gap between them arises, which is aligned with the openings located under the distributor trough 92.

At opposite ends of the base plate 6, two are free rotatable caster wheels Io2 and Io3 of small diameter arranged.

Between the side walls 8 and Io 1st in the rear part of the Cleaning device a tensioning pulley Io4 arranged with a shaft Io5, which extends through the slots 26 and which rests on the bottom of the slots 26, so that the tensioning pulley Io4 rotate can. At each end of the shaft Io5 there is a tension spring Io6 attached (Fig. 1), which is attached at its other end to a ring Io8.

Before using the cleaning device, the user lifts the Cover 14 and lays a roll Ho of absorbent cleaning material (Fig. 2), such as a Tricot, paper, wipe, or similar material is. The roll Ho lies between the side walls 8 and Io and is wound on a core 112 which passes through the Slots 26 passes therethrough; the material rests on the tensioning roller Io4. The user then translates the rings Io8 the protruding ends of the core 112 and, as indicated by the dashed line A, the free end of the material web via the distribution roller 28 and the small guide roller loj, via the undersides of the foam rubber cushions 98 and loo, around the small guide roller Io2 on the front of the cleaning device and around the distributor roller 64. From there,

- ⁸ 009808/0317

He rolls the material web clockwise onto a take-up core 113, which sits on the bottom of the slots 62.

Then the container 82 is filled with a cleaning liquid, while the container 84 is filled with a liquid polishing agent. The user then slides the lever 94 into one such a position that the cleaning liquid flow out and onto the underneath the foam rubber cushions 98 and loo Material web can arrive; the cleaning device is then pushed over the floor or the surface to be cleaned. If that's located under the foam rubber pads 98 and loo Cleaning material has become dirty, the "user presses the two handles 78 and 80 together, which he over the Bowden cable 4o actuates the ratchet wheel 54 in a counterclockwise direction. As a result of the friction between the transverse shaft 52 and the cleaning material located on the winding core Ilj5 the latter rotates clockwise, whereby the The material web is wound onto the winding core 113 from the roll Ho so that clean cleaning material gets under the foam rubber pads 98 and loo. A leaf spring 114 pushes the take-up core 11? to the bottom of the slots 62.

When the cleaning process is finished, polishing takes place of the floor by adjusting the lever 94 so that the bollard liquid gets onto the cleaning material.

When the web is completely on the take-up core is wound, this is removed after lifting the leaf spring 114; a new role will then appear after loosening the Ho Tension springs I06 inserted. The tension pulley Io4 prevents a unintentional unwinding of the web of material.

The distribution rollers 28 and 64 ensure that the cleaning and bollard liquid is distributed over the entire width

the foam rubber pad 98 and loo. On the cover 14 is a knurled knob 115 is attached by means of a clamp or in some other suitable manner. This can be taken off and on the protruding end of the cross roller 52 are placed, in order to achieve a fast turning of the winding core 113, when the material web is removed from the cleaning device should be before it is completely unwound from the roll Ho.

It does not necessarily need a web of material in the form of a Role to be used, but the cleaning material can also consist of cut leaves, which are taken one by one from a suitable holder; the cleaning material can also be used in the form of sheets, one edge of which is attached to a solid Part are attached like a book, the sheets are removed for use one at a time.

In a modified embodiment, the base plate 6 be attached to the cleaning device so that it is raised and lowered relative to this by a small amount can be. The rare parts 68 and 7o of the handle holder are attached to the side walls 8 and Io with the help of pins, which pass through vertical slots, or by similar devices which allow vertical movement allow the handle holder opposite the rare walls and bind directly to the base plate. By lifting the The handle holder can thus hold the base plate 6 with the foam rubber cushions 98 and 100 opposite the remainder of the cleaning device are raised, whereby the transport of the material web over the foam rubber cushions 98 and loo away is made easier with the aid of the latch arrangement described.
