Definitions

  • the present invention relates to a scraper blade for paint scraper intended for removing paint from a surface, comprising at least one scraping edge, the scraping edge being divided into at least two abutting portions extending along the scraping edge, which, upon abutting scraping action, extend transversely to the direction of scraping. Further, the present invention relates to a paint scraper comprising said scraper blade.
  • GB 208,317 discloses a paint scraper having its blade disposed in a plate at a right angle to a handle, the edge of the blade being provided with pointed teeth.
  • U.S. Pat. No. 4,200,948 describes a paint scraper which has a blade holding portion having a holding slot, in which slot a blade is releasably mounted.
  • the blade has two different, opposed edges. The first edge is straight and smooth, and the second edge is serrated and has pointed teeth.
  • U.S. Pat. No. 4,759,092 discloses a scraper provided with a releasable, sawtoothed edge.
  • U.S. Pat. No. 3,789,450 describes a painter's tool comprising an angular shaped blade, the first edge of which is straight and the second edge of which comprises a straight edge portion and an edge portion having angular shaped, pointed teeth.
  • GB 1,265,189 discloses a tool for removing paint, which comprises a plurality of metal blades, the edges of which are serrated and have pointed teeth
  • U.S. Pat. No. 3,530,524 upon which the preamble of claim 1 is based, discloses a scraper blade for paint scraper intended for removing paint from a surface, comprising a scraping edge, the scraping edge being divided into several abutting portions extending along the scraping edge, which, upon abutting scraping action, extend transversely to the direction of scraping. These abutting portions extend parallel to said surface.
  • the object of the present invention is therefore to provide a scraper blade and a paint scraper which require less force to remove covering, especially paint, from a surface, without scratching and damaging the underlying surface, and which have an effective scraping effect.
  • a scraper blade for a paint scraper intended for removing paint of the kind defined in the preamble of claim 1 where the scraper blade comprises the special feature that each abutting portion is convex in the plane of the scraping edge, whereby an effective scraping effect is obtained.
  • the abutting portions are the portions which engage with the covering, the layer of paint, e.g., and provide a scraping effect on said covering.
  • coverings such as layers of paint, which cover various surfaces, are assumed to be more or less soft.
  • scraping abutting points are obtained at several different levels in the paint, providing a scraper blade with a more effective scraping of rough surfaces and layers of paint, but also of more even layers of paint, compared to conventional scraper blades.
  • Scraping abutting points at several different levels in the paint upon abutting scraping action, results in less force being required, upon scraping the surface, to remove paint, whereby the scraping becomes easier and the risk for damaging the surface under the paint is minimized.
  • the convexity of the abutting portions results in the avoidance of damaging the surface, in the form of scratches, since no sharp edges risk scratching the surface.
  • each abutting portion is continuous in the plane of the scraping edge, in that each abutting portion extends continuously along a continuous curve.
  • the scraping edge is wave shaped in the plane of the scraping edge, and each abutting portion forms a part of a crest of the wave shape.
  • This embodiment is especially suitable for considerably rough surfaces and layers of paint having many valleys and elevations.
  • the scraping edge can also be wave shaped transverse to the plane of the scraping edge. This provides abutting portions which are displaced in the direction of scraping, which also enhances the scraping effect of the scraper blade.
  • the longitudinal extensions of the abutting portions are of different lengths. This further enhances the scraping effect, inter alia, when the surface and the layer of paint are rough, and prevents an abutting portion, upon scraping action, from going into a furrow formed by another abutting portion having the same longitudinal extension.
  • each abutting portion upon abutment, makes an angle with the surface, in the plane of the scraping edge, which is always less than 90°, preferably less than 30°.
  • each abutting portion upon abutment, makes an angle with the surface, in the plane of the scraping edge, which is less than 15°.
  • the present invention provides a paint scraper for removing covering, especially paint, from a surface, where said paint scraper comprises a scraper blade according to any of the claims 1 to 6 .
  • FIG. 1 is a schematic side view of an embodiment of the scraper blade according to the present invention
  • FIG. 2 is a cross section of the embodiment of FIG. 1 .
  • FIG. 3 is a perspective view of an embodiment of the paint scraper according to the present invention.
  • FIG. 1 shows an embodiment of the scraper blade according to the present invention, the both longitudinal margins of which are transversally chamfered (see FIG. 2 ), which substantially provides two longitudinal scraping edges, a first scraping edge 5 at the upper longitudinal margin of the scraper blade, and a second scraping edge 6 , opposite the first scraping edge 5 , at the lower longitudinal margin of the scraper blade.
  • the first and second scraping edges 5 , 6 , of the embodiment are divided into several abutting portions 7 . 1 , 7 . 2 , 7 . 3 , 8 . 1 , 8 . 2 , which, upon abutting scraping action, extend transversely to the direction of scraping, and additionally are continuous in the plane of each scraping edge 5 , 6 .
  • Each scraping edge 5 , 6 is wave shaped in its scraping edge plane, and each abutting portion 7 . 1 , 7 . 2 , 7 . 3 , 8 . 1 , 8 . 2 is convex in the plane of the scraping edge 5 , 6 and forms a part of a crest of the wave shape.
  • the longitudinal extensions of the abutting portions 7 . 1 , 7 . 2 , 7 . 3 , 8 . 1 , 8 . 2 in the plane of each scraping edge 5 , 6 are of different lengths.
  • FIG. 2 shows a cross section of the embodiment of FIG. 1 .
  • An elongated scraper blade can for example be provided with two scraping edges at one longitudinal margin, or the scraper blade itself can have another overall design, but still comprise the unique scraping edge according to the present invention.
  • the scraper blade can for example be triangular, provided with a scraping edge along all or any of the margins of the triangle shape.
  • FIG. 3 shows a perspective view of an embodiment of the paint scraper according to the present invention, to which the scraper blade of FIGS. 1 and 2 is attached, for scraping with one of the scraping edges 6 .
