Definitions

  • ABSTRACT A scraper comprises a blade holder, a lamelliform blade and a cover member.
  • the blade holder has a holding edge and includes two arms that are resiliently disposed with respect to each other along a cutting edge.
  • the blade is removably held between the resiliently disposed arms of the blade holder along the cutting edge thereof.
  • the cover member has a substantially U-shaped cross-section with free longitudinal edges and is capable of being pushed over the cutting edge of the blade holder when the scraper is not in use and over the holding edge of the blade holder to enlarge the area of the scraper to be gripped during use.
  • Guidemeans is located on the blade holder and the cover member for guiding movement of the cover member with respect to the blade holder between a first position over the cutting edge and a second position over the holding edge.
  • the guide means includes means for pivoting the blade holder with respect to the cover member and linear guide means extending along the length of the scraper to locations short of I the respective ends of the scraper.
  • This invention relates generally to scrapers of the kind comprising a blade holder of U-shaped cross section which simultaneously serves as a handle, and a lamelliform blade which is easily replaceably held between the two resilient arms of the blade holder, the cutting edge of the blade being arranged to be covered during disuse of the scraper by means of a change covering which is also of U-shaped cross section and can be pushed over the blade holder.
  • scrapers may be carried around in the pocket without danger but have the disadvantage that the covering for the blade is a separate part which may easily get lost.
  • a scraper has already become known, in the U- shaped blade holder of which a slide is arranged be tween one arm of the blade holder and the blade, which slide can be moved in the direction toward the cutting edge of the blade. It is the purpose of this slide to cover the cutting edge during disuse of the scraper and a certain advantage can be seen in the fact that the slide cannot get lost.
  • scrapers are not only more expensive in manufacture than the scrapers having a separate change covering, but their gripping surface cannot be enlarged as is the case with the change covering of the above kind. Therefore, such a scraper must have a great width, since otherwise it cannot be securely gripped.
  • scrapers have become known which consist of a holding plate for the blade and a cover plate adapted to be connected to said holding plate and arranged to be moved on the holding plate in such a manner that during disuse of the scraper the cutting edge of the blade is covered thereby.
  • the holding plate and the cover plate must be rather long so as to ensure a good mutual guidance. Therefore, the dimensions of the scraper and the material expenses are considerably high, which counts if it is considered that such scraper is a wholesale article.
  • the object of the present invention to eliminate these shortcomings of conventional scrapers, and to combine in a scraper of the kind described hereinabove the blade holder with its covering to a unit in such a manner that the covering may be used in a known manner for enlarging the blade holder after the cutting edge of the blade has been exposed.
  • the present invention provides a scraper which comprises a blade holder of substantially U-shaped cross section and arranged simultaneously to serve as a scraper handle.
  • the blade holder has two relatively resilient arms connected by a back. Near the region of said back each arm is provided with a groove closed at both ends and extending nearly along the whole length of the blade holder.
  • a cover member has a substantially U-shaped cross section with free longitudinal edges and is capable of being pushed over the blade holder.
  • the cover member has two resilient arms which have interiorly, near one of their ends, two opposed boss-like projections engaging in the grooves of the arms of the blade holder.
  • a lamelliform blade is easily replaceably held between the two resiient arms of the blade holder and has a cutting edge adapted to be covered during disuse of the scraper by the covering.
  • the blade holder For exposing the cutting edge of the blade, for instance the blade holder is pivoted by 180 and thereafter the covering is moved on the blade holder until the ends thereof are in alignment with the ends of the blade holder.
  • the blade holder is enlarged, so that the scraper may be securely gripped the blade may be covered in the same simple manner, namely by drawing off the covering from the blade holder until it can be pivoted by noting that the pivoting action includes shifting the covering onto the blade holder.
  • FIG. 1 is a side elevational view of a scraper according to the invention, the blade holder withits blade being folded into the covering;
  • FIG. 2 is a similar view showing the blade holder pivoted by 180;
  • FIG. 3 is a similar view showing the scraper ready for use
  • FIG. 4 is a section on the line IV'IV of FIG. 1.
  • the drawing shows a scraper according to the invention which comprises a blade holder 1 of substantially U-shaped cross section and having two relatively resilient, spaced apart arms 2 and 3 connected by a back extending along the length of the arms at one longitudinal edge thereof.
  • the blade holder 1 has a holding edge and a cutting edge.
  • the arms 2 and 3 are constructed to extend from the back over part of their width parallel with respect to one another and then to converge in the direction towards the other longitudinal edge of the arms so as to resiliently engage each other in the region of said other longitudinal edge of the blade holder 1, to hold a lamelliform blade 4 in an easily replaceable manner.
  • a covering or cover member 5 of substantially U-shaped cross section and having likewise relatively resileint, spaced apart arms 6 and 7 is attached to the blade holder 1 for pivotal and sliding movement with respect thereto.
  • Arms 6 and 7 include longitudinal edges 6a and 7a.
  • the arms 2 and 3 of the blade holder are provided near the back thereof with linear guide means including two opposed grooves 9 and 10 which extend nearly along the whole length of the blade holder 1 and which are closed at both ends thereof.
  • the arms 6 and 7 of the covering 5 are provided interiorly, near or adjacent one end of the cover member 5, with two opposed boss-like projec-' tions 11 and 12 which for guiding purposes engage in the grooves 9 and 10 of the blade holder 1.
  • the arms 2 and 3 of the blade holder are provided each at the ends thereof with transverse recesses 13 and 14 which communicate by one of their ends with the grooves 9 or 10.
  • Two open-ended recesses 8 which register with each other are provided in the arms 6 and 7 of the covering 5.
  • the cutting edge of the blade 4 is exposed by gripping the blade holder 1 in the area of the open-ended recesses 8 in the covering 5 and pivoting it by 180 in relation to the covering 5, as shown in FIG. 2.
  • the latter receives in its recesses l3 and 14 of its arms 2 and 3 the boss-like projections 11 and 12 of the covering 5 when swinging out of the covering 5.
  • the boss-like projections 11 and 12 of the covering 5 are forced out of the recess 14 in the arms 2 and 3 of the blade holder 1 and pressed into the grooves 9 and 10.
  • the covering 5 is then moved on the blade holder 1 until its ends are in alignment with the ends of the blade holder 1, as shown in FIG. 3, whereupon the scraper is ready for use.
  • the blade holder 1 is swung out of the covering 5 in the manner described above and, after the blade holder 1 has been pivoted by 180, the covering 5 is moved on the blade holder 1 until its ends are in alignment with the ends of the blades holder 1, as shown in FIG. 1.
  • the scraper proposed by the present invention provides the folowing advantages.
  • the blade 4 of l the scraper is relatively firmly clamped between the arms 2 and 3 of the blade holder 1, so that a reliable mounting or positioning of the said blade is ensured.
  • replacement of the blade 4- is rendered more difficult.
  • the blade 4 can be removed from the blade holder simply and without danger.
  • the covering 5 of the scraper is pivoted through somewhat less than 180' from the position of FIG. 3. That is, the position of the cover member 5 is inclined with respect to that of the blade 4.
  • a scraper comprising:
  • a blade holder having a holding edge and including two arms that are resiliently disposed with respect to each other along a cutting edge
  • a cover member having a substantially U-shaped cross-section with free longitudinal edges and capable of being pushed over the cutting edge of the blade holder when the scraper is not in use and over the holding edge of the blade holder to enlarge the area of the scraper to be gripped during use, and
  • guide means located on the blade holder and the cover member for guiding movement of the cover member with respect to the blade holder between a first position over said cutting edge and a second position over said holding edge
  • said guide means including means for pivoting the blade holder with respect to the cover member and linear guide means extending along the length of the scraper to locations short of the respective ends of the scraper.
  • said grooves are located near the holding edge of the blade holder and said projections are located near the free longitudinal edges of the cover member and adjacent one end of the cover member.
