Cleaning cloth and equipment and method of cleaning Städningslinne och städningsanordning samt förfarande för städning

The invention relates to a cleaning cloth according to the preamble of claim 1 for use in cleaning, washing, rinsing, wiping, etc., of various surfaces, such as floors, walls, windows, doors, table tops and the like. The invention further relates to a device for supporting and using a cleaning cloth according to the preamble of claim 4 and a method for cleaning.

In the past, it has been known to use a mop, which is a suitable material for cotton, man-made fibers, etc., to support the cleaning device frame. Various solutions for mopeds and their attachment to the frame are known e.g. U.S. Patent Nos. 3,029,454; 3,711,886; 4,715,081; and 4,914,778; or U.S. Patent Nos. 68514 and 88670; and U.S. Patent Nos. 955346 and 961107. In each of these, the mop cloth attached to the frame substantially corresponds in size and form to the frame. In addition, the mop may be; fitted with "fringes" extending from the edges of the mop.

• · • · ···

A disadvantage of the known solutions has been that they do not allow efficient use of the entire mop cloth surface for cleaning • 0 ♦, but are adapted to wipe the surface to be cleaned only on its underside. When the mop becomes dirty on the underside of the wiper while cleaning, it must be removed from the rack and washed or replaced. This will interrupt cleaning for washing, or require the use and replacement of more mops. Laundry equipment or arrangements and / or the number of replacement mops will increase the cost of cleaning and make it more difficult to monitor and control the amount of cleaning supplies and materials in general.

2 108397 In addition, devices and methods of the prior art require the use of a plurality of differently structured and discrete devices, such as wiping cloths, laundry cloths, and drying devices.

As can be seen in Figure 4a, when wiping the surface to be cleaned (not shown), the cloth 9 is pressed against the surface only V; with one spatula 7, with the other remaining free. This second spatula can be used to pre-clean the surface • to be cleaned, eg from loose stones or other debris, which otherwise. . would end up in a cleaning cloth. In the situation of Figure 4b, the cloth 9 • · ♦ * ·. * Is wound over the body part 6, and the second spatula 7 can now be used e.g. for drying. The solution achieves significant benefits: **. · Eg when cleaning windows, as now only · ·; ***: only one cleaning device that can be used for both self-replaceable / rotatable cloth 9 and • 'spatula 7 drying.

According to one embodiment, the gap between the bar means 8 and at least one of the blades 7 is adapted to be substantially small, 8 108397 or even such that the bar 7 is pressed against the bar means 8. This produces a retaining effect similar to that of the spring element 4.

Furthermore, the bar means 8 may be provided with a slot or slot 21 extending substantially along its entire length, i.e. the bar means 8 will form a so-called. C structure. As shown in Fig. 5, such a rod can be threaded with a cleaning cloth 19 having a special retaining tab 20 provided at one edge thereof, such as a thin rod sewn into the edge, etc., which is threaded into the rod means 8 and from which the cleaning cloth 19 extends. This solution makes it possible to use both sides of the cloth 9 with a single attachment, while the spatulas 7 can be used for e.g. drying. As shown in Figure 5, it is not necessary in all embodiments to provide the cleaning device with a spring element as shown in Figures 1-4.

Fig. 6 shows a solution in which a cleaning cloth 9A and / or 9B of the known type is mounted in connection with the cleaning device 10 to hold it. non-forming cloth; V stitches.

Figures 1-6 show a cleaning cloth holder 10 provided with two spatulas 7 provided with a drying tip 17. In addition to the wiping / scraping properties described above, these spatulas are also utilized in the cleaning process itself because they are used. as elements that. . press the cloth against the surface to be cleaned. Pressing with a spatula like the one described gives the advantage of cleaning with a spatula. because the surface pressed against the cloth to be cleaned remains substantially small, while the pressure against the surface is substantially increased. Thus, for example, a damp cloth slides: on a surface that is easy to clean while maximizing its cleaning effect.
