Definitions

• the present invention relates to a textile floor wiping covering made of flexible textile material which can be releasably clamped onto a clamping frame of a manual cleaning device, the floor wiping covering with its edge regions projecting at least partially laterally over the holding surface of the clamping frame and being stiffened in these edge regions.
• a large number of manually operated floor cleaning devices for wet and dry cleaning of floor surfaces and possibly walls are known, in which a tenter frame is attached to the front of a handling handle.
• a textile covering can be attached to this clamping frame as the actual cleaning element.
• the attachment is usually carried out by expandable or hinged wings of the clamping frame, which engage in corresponding pockets or tabs on the floor wiping surface.
• Such designs have the basic advantage that the wiping surface is easy to replace.
• the floor wiping covering is stretched on the downward-facing clamping or holding surface of the tensioning frame in such a way that the cleaning-active cleaning side of the textile covering is directed outwards, ie also downwards.
• it has become customary to make the floor wiping surface larger than the holding surface of the tenter frame, ie to let the wiping surface either protrude all around or partially laterally beyond the outer edge of the tenter frame.
• the cleaning effect of such a wiping device is the better, the more uniform the contact of the cleaning side of the wiping covering over its entire active surface with the surface to be cleaned.
• the wiping surface when cleaning floor and wall surfaces, the wiping surface should lie snugly on the surface to be cleaned and, if possible, should not warp or bend even when pressed firmly to remove stubborn dirt. While this requirement is easily met in the area of the smoothly tensioned holding surface of the stenter, the required stability in the unsupported, protruding edge areas of the floor wiping covering is largely not guaranteed. According to EP 0 630 606 B1, the state of the art suggested that a reinforcement made of cord-like or wire-like material be drawn into the wiping covering.
• the wiping covering known from it still has outward, unreinforced edge areas, and on the other hand, such reinforcement only increases the bending stiffness of the linear outer edge, but not the area of the protruding area transversely to the outer edge.
• reinforcement it is known from EP 0 664 1 00 A1 to fold over the edges of the floor wiping covering on the upper side and to sew or glue them there.
• the textile material of the wiping covering is relatively flexible or limp in itself, also to ensure a good cleaning effect. Due to the essentially linear seams or glued seams, an increase in shape retention in the seam direction, ie in the edge direction, is at best achieved.
• the rigidity is not sufficient. Even the double-layered textile material has only a low inherent rigidity in its outer edge areas.
• the present invention is based on the task of providing a textile floor wiping covering with the features mentioned at the beginning, which in its edge regions projecting laterally beyond the holding surface of the tenter frame has better inherent rigidity and dimensional stability, both in the direction of the edge and across it.
• the invention proposes that at least partially flat stiffening strips are firmly attached to the textile material along the edge regions.
• the stiffening strips according to the invention form flat reinforcing elements which are fixed on the textile material on the back of the floor wiping covering in the edge regions protruding beyond the holding surface of the tenter frame.
• a particular advantage of the configuration according to the invention is that the inherently flexible textile material of the floor wiping covering is supported flatly by the stiffening strips, i.e. whose bending stiffness is increased both longitudinally and transversely to the edge extension.
• the edge areas are thus given increased inherent stability and dimensional stability for the first time.
• the increased bending stiffness is essentially determined by the mechanical properties of the stiffening strips.
• the textile material can be optimized particularly advantageously with regard to its properties of cleaning, such as surface structure, absorbency or other parameters, without having to compromise on its mechanical stability.
• This aspect is of particular importance insofar as there is a certain conflict of objectives with the stiffening methods known in the prior art: on the one hand, the textile material of the floor wiping covering must be relatively flexible so that it can be folded over or sewn on one or more times at the edge. On the other hand, however, it should be as dimensionally stable as possible so that the edges fit snugly and do not bend or warp.
• the present invention enables a coherent and consistent approach to this for the first time.
• the stiffening strips are preferably approximately as wide as the edge regions. These are supported across their entire width. If the stiffening strips extend over the length of the edge regions, ie are continuous along an edge or also run around the entire outer edge, the bending stiffness in this direction is also optimized.
• stiffening strips only on individual edge areas or in sections. This enables, for example, special edge or corner reinforcements.
• the stiffening strips preferably have a higher bending stiffness than the textile material of the wiping covering. This dimensional stability of the stiffening strips can be specified practically without restrictions by selecting materials which are less mechanically flexible and / or a corresponding dimensioning, for example with regard to the material thickness.
• the stiffening strips can for example consist of textile material. This should, for example, be a woven or non-woven fabric with harder and / or thicker fibers than with the wiping covering, so that it has greater inherent rigidity. For this purpose, rot-proof plastic fabrics are well suited.
• the stiffening strips can consist of a felt.
• Suitable felt materials are available in material thicknesses of several millimeters and - particularly with increasing thickness - have good dimensional stability. It still has an internal damping effect, so that the risk of damage to furniture or baseboards is reduced when using the floor mop.
• felt is easy to assemble and process, for example sewing, is rot-proof and is, to a certain extent, absorbent and moisture-storing. This can be an advantage for certain cleaning applications.
• the fully absorbed felt gets an increased Dead weight, through which the edges are firmly pressed onto the floor surface.
• stiffening strips are made of plastic film. Even with a relatively small thickness, this generally has good bending elasticity and dimensional stability. Thus, the wiping covering in the edge areas is only insignificantly thicker even with the stiffening insert according to the invention.
• the shape and bending stiffness of the reinforcing strips according to the invention can be further increased in that they have reinforcing ribs.
• These reinforcing ribs are formed, for example, by webs running in the longitudinal and / or transverse direction or crosswise, which are connected to the base material of the stiffening strips or molded on them.
• felt strips can be provided with plastic ribs or plastic film strips can be provided with molded ribs or molded beads.
• One advantage of such reinforcing ribs is that the bending stiffness can be increased in individual areas as required with only a small additional material expenditure.
• the stiffening strips can be glued or sewn onto the textile material of the wiping surface for fastening. Thanks to the stiffness of the stiffening strips, it is sufficient to create punctiform or linear connections between the strips and the textile material, so that the stiffening strips are securely fixed and cannot slip. Of course, flat gluing or multiple sewing can also be carried out in order to produce a particularly secure connection. It is also conceivable to choose other connection options.
• the textile material of the floor wiping covering is turned upwards around the stiffening strips on the outside. This ensures that the floor mop covering also has an active cleaning surface along its edges.
• the stiffening strips are particularly securely edged and a in the textile material Fraying on the edges largely excluded without additional hems.
• a particularly advantageous possibility of fastening the reinforcement strips to the textile material provides that the textile material is fastened on its outer edge with its cleaning side to the edge of the stiffening strip and the stiffening strip is fastened folded over to the rear of the textile material.
• This attachment has the particular advantage that the stiffening strip is particularly securely fixed in the edge region of the floor wiping covering and the connecting seam on the outer edge is completely covered and is therefore protected against damage of any kind.
• the textile material preferably consists of a carrier fabric on which cleaning-active fibers are attached on the cleaning side.
• the carrier fabric can consist, for example, of durable and hard-wearing material, a cleaning plush made of so-called microfibers or the like, for example, is attached to the cleaning side and has a particularly good cleaning effect.
• the wiping surface expediently has an approximately rectangular cut.
• FIG. 1 shows a cross section through a floor wiping covering according to the invention in a first embodiment
• FIG. 2 shows a sectional view through a floor wiping covering according to the invention in a second embodiment
• FIG. 3 shows a schematic view from above of a floor wiping covering according to the invention
• FIG. 1 and FIG. 2 show cross sections through the edge region of a floor mop covering 1 according to the invention, which is clamped onto a - partly indicated - clamping frame 2.
• the floor wiping covering 1 consists of a blank made of relatively flexible textile material 3, which is provided with a cleaning plush 3a on its outer cleaning side.
• a reinforcement strip 4 according to the invention is fastened on the back of the textile material 3, which is, for example, a flat felt strip in the embodiment shown.
• the textile material is turned up around the outer edge of the reinforcing strip 4 and fixed in the area of the inner edge of the reinforcing strip with continuous seams 5.
• the textile material 3 is first sewn or linked at its outer edge with its cleaning side at the edge of the reinforcing strip 4 by seams 5a.
• the stiffening strip 4 is then turned backwards and in turn fastened with internal seams 5 on the back of the textile material 3.
• the stiffening strip 4 extends over the entire width of the edge region with which the floor wiping covering 1 laterally protrudes beyond the stenter 2. This results in a stiffening over the entire width of the edge area.
• the inner edge of the stiffening strip 4 practically abuts the outer edge of the tenter frame 2. Folding up of the edge area around the inner edge of the stiffening strip 4 is thereby suppressed.
• the stiffening strip 4 according to the invention brings a continuous stiffening beyond the holding surface of the tenter frame 2 to the outer edge.
• the stiffening strip 4 can consist of plastic film or other rigid materials.
• an attachment to the textile material 3 can be provided for fastening.
• FIGS. 3 to 6 show a view from above of a floor wiping covering 1 according to the invention as in FIG. 1 or FIG. 2. This shows the versatility in the attachment of the stiffening strips 4 according to the invention particularly clearly. For this purpose, the stiffening strips are hatched in the installed position.
• transverse edges of the floor wiping covering 1 can be reinforced (FIG. 3) or the longitudinal edges (FIG. 4).
• a corner reinforcement is also possible (FIG. 5).
• stiffening strips 4 can either be formed from individual strips or in one piece.
• stiffening strips 4 made of felt have the advantage, in particular in wet cleaning, that they become full Suck water and get an increased weight. As a result, the edge area lies particularly well on the floor surface when wiping the floor.
