Definitions

• the present invention relates to a squeezing device according to the preamble of Claim 1 and a use of a squeezing device of this type according to the preamble of Claim 21.
• a squeezing device for a wiper device having a support, mounted in an articulated way, which supports a wiper cover.
• the support having the wiper cover forms a wiper surface, which may be pressed against a pressing element which is stiff and even and is provided with through openings, so that the absorbent wiper cover may be squeezed out.
• the known squeezing device is only suitable for wiper devices having one single even wiper surface.
• the object of the present invention is to provide a squeezing device and its use so that with a simple, cost-effective construction effective squeezing of wiper devices, particularly those having two spaced and/or slanted wiper surfaces and/or having a three-dimensional support, is made possible.
• One single squeezing procedure shall be sufficent for multiple wiper surfaces and/or a three- dimensional wiper surface.
• An essential idea of the present invention is to implement the pressing element as flexible element.
• the pressing element allows to be clamped over and/or around and/or against the wiper surface(s) for squeezing out the wiper cover.
• the pressing element is tensioned and pressed against the wiper cover transmitting squeezing force to the wiper cover.
• the pressing element may adapt itself to different shapes and outer contours of the support and the wiper cover, even to curved or rounded wiper surfaces.
• the suggested squeezing device is accordingly universally usable.
• the suggested squeezing device is particularly usable for three-dimensional sup- ports with wiper cover, such as those having the shape of a prism or other cross- sectional shapes due to the flexible pressing element.
• a further advantage of the suggested squeezing device is that one single pressing element allows simultaneous squeezing of multiple wiper surfaces of the wiper cover, in particular two wiper surfaces. This allows simple operation and rapid squeezing.
• the use of a flexible pressing element thus also allows the squeezing of a wiper cover of a round wiper device, in which the wiper surfaces pass into one another without a projection.
• the flexible pressing element allows a simple, cost-effective construction of the squeezing device.
• the requirements for adaptation to the particular wiper device and/or its support are less than in the prior art.
• the flexible pressing element it is possible for the flexible pressing element to be impermeable to liquid, so that the cleaning liquid is drained off using the pressing element via channels, grooves, or the like.
• the pressing element it is particularly preferable for the pressing element to be implemented as permeable to liquid per se, particularly as a kind of pressing net.
• the pressing element is advisable for the pressing element to be manufactured from textile or film material.
• textile materials possibly processed in a special way, such as cotton, acetate, viscose fibers, poly- acrylic fibers, polyesters, polyamides, etc., are considered as textile materials.
• Textile materials may be understood to include not only woven fabrics, but also knitted fabrics.
• Film materials are thin, flat, flexible, windable webs made of metal or plastics, such as very thin sheet aluminum having perforations to achieve the permeability to liquid, or e.g. PVC films.
• the specific selection of the material of the pressing element is left to one skilled in the art.
• the flexible pressing element is replaceable and/or adaptable. In this way, simple replacement is made possible in the event of contamination or wear. Furthermore, this allows adaptation to different wiper devices and/or different supports by selection of a suitable pressing element, in particular one which is adapted in its size.
