Description
- The present invention relates to an apparatus for cleaning floor surfaces. The invention is particularly concerned with a suction head arrangement suitable for use with a wet floor cleaning machine.
- It has been known in the past to employ a mobile suction head as part of a machine for the cleaning of floor surfaces, especially a machine for wet cleaning of such surfaces.
- US-A-2,531,370 discloses a suction mop suitable for use in scrubbing floors and the like. This suction mop comprises a mop head including a U-shaped channel in which an inverted squeegee blade can be removably supported.
- US-A-3,434,178 relates to a vacuum cleaner comprising a vacuum suction nozzle having an inlet near the floor, and an elongate floor brush located near this inlet. This brush is resiliently attached to the vacuum nozzle by way of a U-shaped clip coupled to the nozzle by way of a leaf spring.
- US-A-3,371,371 discloses vacuuming equipment for treating floors, in particular a pick-up tool assembly comprising a vacuum head, means for positioning said vacuum head in a fixed functional relationship to the surface to be cleaned, while in use. These positioning means include a non-removable elongate squeegee which is attached to the assembly by a pair of clip elements.
- Furthermore, WO-94/20010 discloses a suction head for a floor cleaning machine comprising a housing and a package consisting of a squeegee blade and a clip element, whereby the size and shape of said clip element and the housing are such that this package can be removably fixed into the housing and the squeegee blade can be removably fixed into the clip element. For obtaining an effective removable fixation of the squeegee blade inside the clip element, the clip element according to this document comprises sharp projections on the inner surface thereof. However, even when using a clip element with such sharp projections in a suction head configuration according to WO-94/20010, a significant amount of skill was found to be required to ensure that the squeegee blade is well fixed over its entire length. Furthermore, the suction head configuration disclosed by WO-94/20010 is sensitive for tolerances in squeegee blade thickness, which also endangers the reliability of the squeegee blade fixation in the clip element.
- In US-A-1, 828, 139, a window cleaning squeegee comprising a holder and a squeegee strip is disclosed.
- It is an object of the present invention to provide a suction head for a floor cleaning machine, comprising a squeegee blade which is removably fixed and having a configuration such that the above-mentioned problems are overcome.
It is also an object of the present invention to provide a suction head configuration which can be simply and reliably operated and allows efficient use of the squeegee blade applied therein.
It has now surprisingly been found that these and other objects can be achieved by the suction head according to the present invention. - According to a first aspect of the present invention, there is provided a suction head for a floor cleaning machine, comprising a housing and at least two packages consisting of a squeegee blade and a clip element, whereby the size and shape of said clip element and the housing are such that these packages can be removably fixed into the housing, and whereby the squeegee blade contains one or more holes of which the size and shape are such that they fit to clipping parts present at the inner surface of clip element so as to removably fix the squeegee blade into the clip element.
- The invention is concerned with a suction head for a floor cleaning machine, preferably a wet floor cleaning or floor polishing machine. This suction head comprises at least two removable packages consisting of a removable squeegee blade and a clip element.
It was found to be remarkably simple to prepare this suction head for use as part of a floor cleaning machine: the squeegee blades could be easily and reliably fixed into the clip elements and the thus formed packages could in turn be simply fixed into the housing. As a result, a good fixation of the squeegee blades in the housing was guaranteed, resulting in a good suction result.
Furthermore, the suction head configuration of the invention was found to be unexpectedly versatile in that it could be used with squeegee blades of varying thickness. In addition, when using this suction head arrangement, it was found that replacement of squeegee blades could be carried out quickly and easily. - At least two packages are applied in the suction head of the present invention. Such use of more than one package overcomes any transport and storage problems, which may occur due to the oblong shape and length of usual suction head arrangements. Another advantage of applying more than one package segment is that this allows replacement of only that segment which has been worn out.
For reasons of easy exchange of these package segments, they have preferably the same size. - In order to ensure a tight fixation of the package in the suction head, U-shaped clip elements are preferably applied which can be tightly fixed in a similarly shaped -i.e. inverted U-shaped- channel in the housing of the suction head.
For obtaining an effective removable fixation of the squeegee blades into the clip elements, it is desirable that more than one clipping parts are present on the inner surface of the clip elements. For the same reason, said clipping parts are preferably arranged at regular intervals along the length of the clip elements. - In view of the construction of the packages according to the invention, which warrants easy removability of the squeegee blades, we found that the operating lifetime of the squeegee blades could be considerably increased when applying oblong squeegee blades of which at least two edges can be used for cleaning purposes. Most preferably, the construction of the suction head of the present invention is such that all four edges of the squeegee blades can be used for cleaning purposes. When one of the edges has been worn out, these squeegee blades do not need to be replaced; they can, instead, be turned along their longitudinal and/or vertical axis after having removed them from the package, such that another edge is applied for cleaning purposes.
- The squeegee blade suitable for use in the suction head of the present invention, is preferably somewhat flexible; it is, therefore, desirably made of a plastic material such as poly urethane or rubber. As indicated above, good cleaning results were obtained with a squeegee blade having an oblong shape; its length and breadth are preferably in the range of respectively 0.5-1.2 m and 0.03-0.1 m. The thickness of the squeegee is effectively in the range of from 3-6 mm.
- The invention is illustrated by figures 1-3, of which:
- Figure 1 shows schematic drawings of (a) a side view of a squeegee blade, a clip element and a package according to the invention and (b) cross sections of said elements along the line A-A;
- Figure 2 shows schematic drawings of cross-sections of said package, the part of a suction head of the invention substantially consisting of a U-shaped channel, and said channel into which said package has been positioned;
- Figure 3 shows a schematic view of a complete suction head of the invention.
-
- Referring now in detail to these drawings, in Figure 1 (1) indicates a package of the invention consisting of a squeegee blade (2) and a clip element (3). It is also shown in this Figure how the squeegee blade can be removably fixed into the clip element by way of clipping parts (5) located on the inner surface of the clip element (3), which parts fit into holes (4) present on the squeegee blade (2). The side view of the package (1) shows an embodiment in which the clip element (3) contains rectangular holes in between the clipping parts (5). Since these clipping parts (5) are present on the inner surface of clip element (3), they are not shown on said side view.
- In Figure 2, it is shown how the package of the invention (1) can be tightly fixed into the housing (7) of a suction head by way of a U-shaped channel (6). Adequate fixation is accomplished by applying a clip element having a part (8) which can be attached to the housing as indicated.
- In Figure 3, a suction head (9) according to the present invention is shown which can be coupled to any suction system suitable for use in a wet floor cleaning machine.
- It is emphasized that the suction head and package shown in the Figures illustrate only one preferred embodiment of the invention and that various constructional alternatives will be immediately evident to the man skilled in the art, without departing from the scope of the prsent invention.
