DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a wipe cover for floor cleaning, featuring a wipe-material layer having pile threads projecting from this layer in the direction of the surface to be cleaned, and means for securing to a retainer.
A wipe cover of this type is known from the German Patent 31 39 245 C2. A disadvantage here is its limited water- storing ability, so that it is possible to work with only a relatively small amount of water if the intention is to omit rewiping.
The object of the invention is to produce a wipe cover which, given small usage of material for the wipe-material layer, improves the water-storing ability in order to avoid rewiping, despite increased use of water.
SUMMARY OF THE INVENTION
According to the invention, at least one layer of non-woven fabric is provided, forming an edge projecting beyond the wipe-material layer. This non-woven fabric has increased water-storing ability in comparison to the pile threads made at least in part of synthetic fibers, between which only small amounts of water can be held. The edge, made of just this non-woven fabric and projecting beyond the wipe-material layer, first releases the water on the surface to be cleaned and loosens the dirt. The pile threads of the wipe-material layer following in the cleaning direction lift the dirt from the surface to be cleaned, and the edge of non-woven fabric, following in turn, absorbs the water again, now laden with dirt. Thus, increased water usage is possible in one work operation. Additionally, the edge acts as a buffer since, because of the relatively low stiffness of the non-woven fabric, the edge compresses when bumping against a piece of furniture or a baseboard, and thus lies between the retainer and the piece of furniture.
Particularly economical usage can be made of the wipe-material layer it is essentially the size of the area covered by the retainer and lies directly thereunder. In this case, only the non-woven layer projects beyond the retainer. However, since the transfer of force from the retainer to the wipe cover occurs significantly in the region of the retainer itself, and the cleaning performance of the unstressed edges must be estimated as very low in comparison to the surface under the retainer, the cleaning performance is not significantly lower overall.
To further improve the effectiveness of the wipe cover, at least two layers of non-woven fabric can be provided, thereby achieving a double-layering of the edge, as well. Due to the additional layer of non-woven fabric, a further increase in water storage is possible inside the wipe cover. This water supply is released by exercising pressure via the retainer, and can be absorbed again in response to diminishing pressure.
The layer facing the surface to be cleaned can have a cut-out in which the wipe-material layer is embedded. In this way, it is possible to improve the contact of the edge on the surface to be cleaned, since the cut-out layer of non-woven fabric is moved closer to the surface to be cleaned.
To increase durability, the joining of the wipe-material layer to the first layer is configured so as to be concealed between this layer and the second layer of non-woven fabric. The place of junction is thus not exposed to the mechanical stresses from the cleaning process itself Thus, it is possible to dispense with a wear-resistant thread in the case of a seam.
By joining the ends of the at least two layers of non-woven fabric, the seating of the edge on the floor is uniform and the deformation of the edge, for example when washing the wipe cover, is decreased.
In another specific embodiment, an edge increasing progressively in width can be provided, the respective upper layer overlapping the lower layer. Thus a seating of the individual layers on the floor at varying distances to the retainer is achieved, and water absorption and release are promoted.
In another aspect of this invention, the formation of fringe using incisions in the nonwoven edge projecting beyond the wipe-material layer promotes take-up of dry
