Definitions

  • the present invention relates to a cutting tool according to the preamble of the claim.
  • the cutting of a gypsum board is normally carried out in a horizontal plane on a bench intended for the purpose. First, measurements are marked out at both ends of the board at points of the desired width, thereafter a straight-edge, i.e. a maxi ⁇ mally straight plank or a metal ruler, is placed from one mark to the other.
  • the gypsum board liner is scored along the side of the straight-edge by using a craft knife, and the gypsum is impact-fractured, the board is folded to rest on the liner of the other side, and a cut is made at the fold. A cut effected in this manner may fracture very obliquely, and the finishing work will take relatively much time.
  • the object of the present invention is to eliminate these dis ⁇ advantages, and to speed up the performance of the work and make it substantially more accurate.
  • this object can be achieved, since in the present cutter the measuring, cutting and guiding are in one and the same device.
  • the frame of the cutter is made up of a steel tube 1, in the example case the inner dimensions of the steel tube are 18x22 mm.
  • the wall thickness is approx. 1.5-2 mm and the length approx. 170 mm.
  • the wall at the same time serves as a handle.
  • At an angle of 90 degrees to the frame tube there is a U- profile 2, attached by welding and having an inner dimension of 15-20 mm, and its wall thickness is approx. 2 mm.
  • the length of the profile is 200-250 mm, and it serves as the guide part in the cutter.
  • the blade holder is a 20-25 mm wide and 80-90 mm long U- profile, at one end of which the blade is secured by a wing screw 8. At the other end of the blade holder there is attached a plastic knob 7, which is tightened from below by a screw 9 and by means of which it is easy to guide the blade.
  • the slide part may be up to 1200-1250 mm long, but the most effective and most accurate work performance is achieved when it is approx. 750-800 mm long, since in that case the cutter can already be used for halving a normal 1200 mm gypsum board. For this reason the maximum required cutting width of the cut ⁇ ter is 600 mm.
  • At one end of the slide part there is secured, by means of a 10 M 5x20 screw and a nut, an approx. 5 mm thick and 20x20 mm wide rubber piece 11. This serves as a stopper, preventing the slide part from becoming detached from the frame tube. When necessary, the stopper is detached and the slide part is removed from the frame tube in order to remove any impurities and gypsum dust from the inside of the frame tube, for example by using compressed air.
  • a cutting width of the device can be seen directly from the scale on the slide part, the forward end 12 of the frame tube serving as the scale-reading point.
  • the cutting width is locked by means of a locking handle 5 attached to the other end of the frame tube by means of a 12 M 8x35 screw and a nut; the handle presses the slide part against the screw.
  • the lever arm of the locking handle will be relatively long, in which case very secure locking is achieved with even a rather small compressive force.
  • cutting can be performed in a horizontal plane on a bench, as with devices used thus far. It is also possible that a stack of boards is resting, for example, against a wall, which is a rather common method in smaller construction projects and renovation projects.
  • the above-mentioned oblique fracturing of the gypsum can be eliminated by means of the present cutter by cutting the liners on both sides of the board, in which case the cut edge will be in a horizontal plane and the finishing work by means of a plane intended for the purpose will be easy and rapid.
  • a door opening may be within part of a board, in which case one part of the board may be of full width and another part must be made narrower. Even in this case the cutting can be done successfully without other tools, owing to this cutting of the liner on both sides.
  • the most efficient operating range of the cutter is approx. from 20 mm to 600 mm, but it can be adjusted steplessly up to 1200 mm. This, however, requires the slide part to be replaced with a longer one, and slide parts can be manufactured as re ⁇ placement parts.
  • the cutter is very easy to use and light to handle. The dimensional accuracy is high, and the directional stability of the cutter is very good, since the U-profile will remain steadily against the edge of the board.
  • the locking handle may be attached also at its other end, in which case the locking of the slide part is carried out from above. It is also possible to manufacture the entire blade holder and even the slide part of plastic or nylon.
  • the steel part may also be made of aluminium.
  • the cutter can also be manufactured as its mirror image for left-handed persons.

Abstract

L'invention porte sur un outil de coupe pour plaque de plâtre. Cet outil est constitué d'un tube formant un châssis (1) auquel est rattaché un élément guide (2). Un élément coulissant (3), équipé de deux échelles de mesure, l'une allant de 0 à 600 mm (15) et l'autre de 1200 à 600 mm (16), court le long du tube châssis. Ce dernier (1) comporte une poignée de verrouillage (5) permettant de bloquer l'élément coulissant sur le tube châssis tandis que sur l'autre extrémité de l'élément coulissant se trouve un porte-lame (4) muni d'une lame (6).
