Abstract
Description
- The present application claims priority of U.S. provisional patent application No. 60/836,363 dated Aug. 9, 2006, the content of which is incorporated herein by reference.
- The present invention relates to a scraper. More particularly, in its intended preferred use, the present invention relates to a wallpaper scraper for scraping wallpaper and the like, in addition to carrying out other related multitask functions, as well as to a method of use associated thereto.
- Devices such as manual scrapers used for scraping, removing or stripping layers or residual portions of wallpaper, paint, hardened glue, and the like, from surfaces, whether substantially flat or other, are well known in the art.
- The Assignee of the present application has developed several of such products, some of which are described in the following US patents and industrial designs: D258,043; D263,277; D414,395; D431,993; D435,408; D463,639; D474,389; U.S. Pat. Nos. 6,829,331; 6,719,620; 6,726,868; 6,742,215; and 6,775,912, the contents of which are also incorporated herein by reference.
- Also known to the Applicant are the following US patents, patent application and industrial designs which describe various scrapers and the like: U.S. Pat. Nos. 851,518; 1,156,783; 1,826,496; 2,402,994; 2,634,498; 2,768,437; 2,882,594; 3,195,232; 3,363,316; 4,813,458; 5,027,512; 5,490,331; 5,706,553; 6,629,331 B2; 2002/0026672 A1; 2002/0095737 A1; 2005/0060891 A1; 200510172432 A1; and Des. 142,468.
- It is also known in the art that surfaces to be treated with conventional scrapers may range in various shapes and sizes, such as walls, floors, ceilings, wooden surfaces, and others, as well as rooms, platforms, furniture, boards, frames, and the like, for example.
- These manual scrapers generally comprise a handle and an end operatively connected to an extremity of the handle for scraping the upper surface of a layer to be removed.
- It is also known in the art that very often, for various time or financial constraints, ft is very important to remove said layers and residual portions of materials as fast as possible, while preventing any harm such as scratches, cutting, and the like, to the users of these manual scrapers. However, conventional scrapers are not always optimally designed for allowing an ergonomic use of the tool, for extended period of portions, and/or for an improved scraping of the material.
- It is also known in the art that some conventional scrapers may be conveniently used for scraping surfaces and the like, but unfortunately, are not always designed so as to prevent the occurrence of undesirable damages to the surfaces being treated, therefore occasionally causing unwanted notches and other damages on the surfaces to be scraped, which subsequently need to be repaired, etc., which is disadvantageous, for obvious reasons.
- It is also known in the art that most conventional scrapers are very task specific, and thus are not ultimately designed so as to enable to carry out a variety of tasks. For example, most conventional wallpaper scrapers are not provided with suitable means so as to enable to subsequently install new wallpaper on the surface having been treated (stripped), so as to not only appose the wallpaper onto a given surface, but also enable a proper seam formation between two adjacent sheets of wallpaper, for example.
- Hence, in light of the aforementioned, there is a need for a device, which by virtue of its design and components, would be able to overcome some of the above-discussed prior art problems.
- The object of the present invention is to provide a device, which by virtue of its design and components, satisfies some of the above-mentioned needs and is thus an improvement over other related devices and/or methods known in the prior art.
- In accordance with the present invention, the above object is achieved, as will be easily understood, with a scraper, such as the one briefly described herein, and such as the one exemplified in the accompanying drawings.
- More particularly, and according to the present invention, there is provided a scraper for manually scraping a layer of material off a given surface, the scraper comprising:
- a handle for manual handling of the scraper, the handle having front and rear extremities;
- a front portion extending forwardly from the front extremity of the handle, at an angle from said handle, the front portion having a top part connected to the front extremity of the handle and a bottom part used for operatively resting the scraper against the given surface to be treated with the scraper;
- a rear portion extending rearwardly from the rear extremity of the handle, at an angle from said handle, the rear portion having a top part connected to the rear extremity of the handle and a bottom part used for operatively resting the scraper against the given surface to be treated with the scraper;
