Definitions

  • 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.
  • 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.
  • 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.
  • the clip element according to this document comprises sharp projections on the inner surface thereof.
  • a window cleaning squeegee comprising a holder and a squeegee strip is disclosed.
  • 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.
  • suction head configuration of the invention was found to be unexpectedly versatile in that it could be used with squeegee blades of varying thickness.
  • 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.
  • 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.
  • said clipping parts are preferably arranged at regular intervals along the length of the clip elements.
  • 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.
  • 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.
  • Figure 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.
  • FIG 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.
  • 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.
