Scraping Blade For Paint Scraper Intended For Removing Paint

Abstract

A scraper blade for a paint scraper intended for removing paint from a surface includes at least one scraping edge. The scraping edge is divided into at least two abutting portions extending along the scraping edge, which, upon abutting scraping action, extend transversely to the direction of scraping, each abutting portion being convex in the plane of the scraping edge, whereby an effective scraping effect is provided.

Description

TECHNICAL FIELD [0001] 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. BACKGROUND OF THE INVENTION [0002] Most of the prior paint scrapers, i.e., tools having a blade used for removing paint from a painted surface, generally have a blade with a straight / planar edge which is applied to the surface so that the whole edge is abutting against the surface. Essentially, a linear abutting surface with said surface is provided. Therefore, a great force is needed to “pierce” the upper paint layer, so that the edge can get a “grip” and penetrate the paint, down to the underlying surface which shall be uncovered. In or...

AI Technical Summary

Benefits of technology

"The present invention provides a scraper blade for a paint scraper that has the special feature of each abutting portion being convex in the plane of the scraping edge. This results in an effective scraping effect, as the 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. The abutting portions are continuous in the plane of the scraping edge and form a part of a crest of a wave shape, especially suitable for considerably rough surfaces and layers of paint having many valleys and elevations. The longitudinal extensions of the abutting portions are of different lengths to further enhance the scraping effect. 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°. The present invention also provides a paint scraper for removing covering, especially paint, from a surface, comprising a scraper blade according to any of the claims 1 to 6."

Problems solved by technology

However, the design of the edge with sharp, pointed or cornered scraping teeth, results in the edge being able to scratch and damage the underlying surface, which in some cases is uneven, and easily getting stuck in a “grip” to the intended surface during removal of paint.

Further, paint scrapers having pointed scraping teeth have poor scraping effect, since pointed scraping teeth have a very small abutting surface with the surface.
