Definitions

  • This invention is about a cutter, that is, about a cutter with a specially designed back(3) which can slide along the back of the blade, surrounding and backing the part to prevent the blade from easily bending and breaking while being used.
  • the traditonal cutter as in Fig.2, dosen't have the back which backs the back of the blade(l), so it tends to be easily bent and broken, especilly along the grooves(2) which are formed diagonally on the surface of the blade, causing the danger of hurting the hand, etc. and inconvenience, while being used
  • this invention aims at providing a cutter which is safer and more convenient because of its blade which is protected from being bent and broken easily while being used.
  • the cutter of this invention is equipped with specially designed back(3) which can back the back of the blade by surrounding the part and a case(6) with a si it(5) formed on the upper side of it: through the hole(5) the button(Bl) fixed on the rear upper part of the back(3) can slide along. So after the blade of the cutter is pushed forward from the front of the ⁇ ease(6) by pushing the button(Bl) forward along the slit(4), if you push the button(B2) forward along the si it(5), the back(3) slides forward along the upper side of the back of the blade, surrounding and backing the part, that is, the upper side of the back of the blade. Howerever, as in the Fig. 11, there can be a gap between the back(3) and the upper part of the blade while the cutter is being used. To prevent such occasion, this invention takes the following two steps.
  • the spring(S) supports the blade so that the blade does not droop but stay raised upward, making the upper part of the blade attached closely to the back(3).
  • the second step as in Fig. 17, the upper part of the blade(3) is fixed with small magnets(M) so that the back(3) and the upper part of the blade are not seperated, making them attached more closely each other by their magnetism.
  • Fig.40 shows the layout of the back(3), the blade, and the button(Bl) when the button(Bl), the blade, and the back are installed in the case.
  • the shaft(l ⁇ ) of the blade button(Bl) in the Fig.40 as in the Fig.43 turns right by the distance of A' and then turns left.
  • This type of blade button also makes it easier to mount the upper part of the blade in the center of the inner part of the blade guard slide when the blade, blade button, and the blade guard are to be mounted on the case.
  • the shaft(l ⁇ ) of the blade button is placed backwars by the distance of A ' from the blade button, which makes it easier for the upper part of the blade to be placed in the center of the blade guard slide as in the Fig.39 and the end part of the extended shaft has an arm(9) for supporting the blade by its elasticity as in the Fig.23 or Fig 30 so that the blade does not droop and the upper part of the blade does not become seperated from the blade guard.
  • the Fig.47 shows the positions of the blade, the blade button, and the blade guard slide when they are mounted on the case as in Fig.39, Fig.40, and Fig.41.
  • the blade button in the Fig.47 as in the Fig.48 differently from the types as shown above thus far, has an arm with it end(7) in the opposit direction(16).
  • the blade button as in Fig. 51 different from the type of blade button as in Fig.48, has an arm(9) at the end of the extended shaft which supports the blade so that it does not droop.
  • the blade button pivot(7) and the blade button arm(9) as in Fig. 51 was mounted on the two holes, that is, the blade button pivot hole(Kl) and the blade button arm hole(K2) as in the Fig.50, on the case as in Fig. 53.
  • the blade as in Fig. 50 is the same as the blade in Fig.14 in type).
  • the cutter in the Fig.67 has a blade guard slide which surrounds and backs the back of the blade so that the blade may not be bent or broken easily;
  • the blade button has not only its pivot but also its arm which supports the blade so that it may not droop! the blade button has its pivot and its arm in the opposit direction so that even when the upper part of the blade button is higher than the lower part of the blade guard slide on the case because of the wide button or the narrow blade, the blade button moves freely along the blade button slot and the blade guard slide moves freely along the blade guard slide button slot, preventing the their clash one another.
  • the cutter case described in the Fig. 68 has its upper seperaton rail(20) and its lower seperation rai 1(19) ;
  • the upper seperation rail(20) seperates the upper passage(R6) of the blade button from the passage of the blade guard slide(R5)
  • the lower seperation rai 1(19) seperates the passage(R4) of the lower part of the blade button from the passage(R3) of the lower part of the blade so that the blade guard slides moves along the passage(R ⁇ ) more stablely and the lower part of the blade moves along the passage(R3) more stablely.
  • the cutter by this invention has a blade guard slide(3) which moves along the upper part of the blade, surrounding and backing the section which needs to be backed; the spring and the arm mounted on the blade button and the magnets mounted on the blade guard slide(3) make the upper part of the blade stay attached closely to the blade guard slide without being seperated eacher other so that the blade does not bend or break easily, preventing the face or the eyes from being hurt by the flying broken pieces of the bladeb and helping use the cutter more safely and conveniently.
  • the blade buttons as in Fig.43, Fig.44, Fig.45, and Fig.46 make the upper part of the blade stay placed in the center of the blade guard slide, and help prevent the upper part of the blade button from colliding with the blade guard slide, so making them move more easily.
  • buttons as in the Fig 48 and the Fig 51 have their blade button pivots and blade button arms in the opposition direction differenltly from the other typs of the blade buttons above, which helps the upper part of the blade stay in the center of the blade guard slide; and even when the blade button is wide or the blade is narrow, such buttons prevent the upper part of the blade button from colliding with the blade guard slide, helping their passages easier.
