Definitions

  • the present invention relates to a tile cutter end device, providing for a tile scoring and cutting, physically and functionally extensible to cutting lengths within half and one metre.
  • FR A, 2553024 A very light machine with push-operable tool carrier is disclosed by FR A, 2553024 in the name of the present applicant. Conventionally, such machine is manufactured in three small embodiments without any claim of professionalism. In this machine are present some arrangements, which demonstrate to be winning and capable of professional and specialistic development.
  • the invention as claimed is intended to remedy these drawbacks.
  • the inventors with ingenious perception have conceived a tile cutter end device, providing the tile scoring and cutting, physically and functionally extensible to cutting lengths within half and one metre, with arrangements and dimensioning aimed to: 1) to reduce the weight of the cutting machine to about one, half with respect of the professional machines of the corresponding configuration, e.g., those described and claimed in the patent application of the same applicant No PCT/EP 91/02527, resulting in respective ratios, between the three corresponding configurations, of Kg 15,5/Kg 6,7; Kg 16,5/Kg 9,5; Kg 34/Kg 12; 2) to increase the cutting performances, particularly in diagonal, thanks to a very deep scoring, provided by the push-operable tool carrier and by the very sturdy frame of the machine.
  • the sturdy frame of the machine furnishes a reaction substantially without dispersions of energy; 3) the application of the cutting pressure: a) as localization, being provided in points which are the most internal and carrying possible, and b) as way by limiting the stroke of the pressers.
  • This is particularly useful in diagonal cut, thanks to the gauge which is offset fulcrumed, whereby the corner of the tile encumbers less with respect to the parts of the machine.
  • the ratio: power arm/weight arm is higher, while for limiting the stroke an adjustable screw with knob is provided; 4) to offer a clear display of the position of the tile and of the sections to be cut and to render the cutting of small sections possible on tiles having an average ratio: size/difficulty of cut, even in diagonal.
  • the swingable gauge per se known, as said, is offset fulcrumed and provided with a double scale: the first furnishing side distances and the second diagonal distances, with autonomous indices of reading with references disposable during the cut, the positioning or the removal of the tile or of its sections; 5) the employment of a push-operable tool carrier of the kind disclosed in the patent application No EP 92116115.4, according to an embodiment appropriated to the use with this machine; 6) a tramplable stopping pedal functioning also by hanging hook and/or 7) a device operating an anti-slipping effect in the way of "sealskin".8) The provision of a tool carrier with a screw adjuster which may be optionally used to limit the stroke in the interval adapted to the thickness of the tile.
  • the machine is made of reduced weight.
  • the weight is reduced to about one half of a conventional professional machine e.g. according to the patent application of the same applicant No PCT/EP 91/02527 of equivalent configuration.
  • the weight are as follow: for a machine having the cutting power of tile of 52 cm of side or diagonal 6,7 kg versus Kg 15,5; for a machine having the cutting power of tile of 62 cm of side or diagonal 9,5 kg versus kg 16,5; and, for a machine having the cutting power of tile of 92 cm of side or diagonal about 12 kg versus 34 kg.
  • the scoring pressure may be exalted and more and more deepened, whereby to reduce the strength of the tile to the cut at a level lower than the stress provided by the machine, despite lighter than 7 kg, with a cutting press provided inside, i.e., with lever arm ratio not very advantageous.
  • a cutting press provided inside, i.e., with lever arm ratio not very advantageous.
  • the tile, deeply scored as wanted and stressed in a point relatively internal has good chances to cut easily and correctly.
  • a tramplable pedal workable by the operator, to prevent the slip of the machine.
  • This pedal is also shaped in order to provide an hook, for a possible hanging or for togging, when possible, with pin or the like.
  • the tool carrier is realized in accordance with the principle of patent application No EP 92116115.4 but in a manner congruous with this kind of cutting machine.
  • this machine it is not possible to cut with good results the tiles "Enduro", there is a very wide range of tiles which for their cut, instead of this machine, would require machines whose weight and cost are twice as much, which are slow and scarcely handlable and that, in at least the 50% of the cuts, oppose difficulties in the positioning of the tile.
  • a machine tile-cutter end 01 providing the tile scoring and cutting, physically and functionally extensible to cutting lengths within half metre, (figures 1 and 11) and one metre (figure 13) comprises, conventionally, a frame 1, made of light alloy, including two pieces 1', 1" (figure 7).
