Definitions

  • the invention concerns a manually operable device for cutting plate-shaped elements, for example, ceramic tiles.
  • Such a device is used in order to adapt the tiles to the dimensions and shape of the area available for them to be laid, such as in the areas bordering with walls, floors or other obstacles.
  • the prior art comprises devices provided with a surface on which a tile to be "split” is placed and with a horizontal beam placed above said surface and guiding a sliding element, movable from a first position in line with a side of said plate-shaped element to a second position in line with the opposite side of of the plate-shaped element.
  • the sliding element is equipped, on its upper side, with a handle and, on its lower side, with a tool for cutting the tile along a "split" line and with a projection designed to be pressed down - at the end of a cutting stroke - in an area astride the incision to cause the "splitting" along said cutting line: said projection follows said cutting tool when the sliding element is moved from said first position to said second position.
  • Such a device enables the cut of the tile to be effected only in the outward stroke, that is in the stroke of the sliding element from said first position to said second position, the subsequent "splitting" may be effected only at the end of the return stroke, that is after the sliding element has been brought back in said first position, having overturned the handle.
  • the invention resolves the said technical problem by adopting a device for cutting plate-shaped elements, comprising a base supporting a plate-shaped element, a sliding element sliding on respective guide means from a first position in line with a side of said plate-shaped element to a second position in line with the opposite side of the plate-shaped element, and vice-versa, said sliding element being provided with a handle, at one end, with cutting means and pressing means, at the opposite end, said cutting means being followed by said pressing means when the sliding element is moved from said first position to said second position, characterized in that said cutting means are followed by said pressing means even when the sliding element is moved from said second position to said first position.
  • the advantages offered by this invention are: elimination of dead time; possibility of cutting and splitting the plate-shaped element in both directions, as preferred by the operator, greater productivity.
  • the device according to the invention comprises a base plate 17 ( Figure 5) which acts as a support for a plate-shaped element 28, P, for instance, a ceramic tile to be split.
  • the base plate 17 is equipped with risers 18, 19, which may be equipped with respective end forks 22 in which the ends of a guiding beam 21 are inserted and fixed with respective pins 23.
  • the device according to the invention further comprises a sliding element 1, 2, tiltable with respect to said guiding beam and slidable on it.
  • Said sliding element 1, 2 is provided with a body 2 ending at its outer end with a handle 1 slightly inclined with respect to the direction of movement of the sliding element.
  • the body 2 widens at its inner end with an advantageously trapezoidal profile, constituting an adequate mass for the arrangement of the cutting tools and for manoeuvring.
  • the body 2 is provided at said inner end with first pressing means and second pressing means: the first pressing means consists of a first pair 3 of projections diverging transversely downwards, said first pair 3 being placed at an intermediate position between the longitudinal ends of said body 2; the second pressing means consists of a second pair 4 of projections diverging transversely downwards, said second pair being placed in line with one of the longitudinal ends of said body 2.
  • a first cutting tool 15 for instance of a rolling type, is placed, said cutting tool being supported to a first pair of lower wings 5 of the body 2, equipped with a respective hole 11 in which the axis of the first cutting tool 15 is fixed.
  • a second cutting tool 14 is placed at the end of said body 2 opposite to the end in line of which the second pressing means 4 are placed.
  • Said second cutting tool is supported to a second pair of lower wings 13 of the body 2, equipped with a respective hole 12 in which the axis of the cutting tool 15 is fixed.
  • the cutting tools 14, 15 are inserted in a longitudinal lower groove 6 of the body 2.
  • the cutting tools 14, 15 exhibit working ends lying substantially on a same cutting plane A, said pressing means exhibiting working ends lying at predetermined different distances from said cutting plane A.
  • Said first pressing means 3 exhibit a corresponding working end parallel to said cutting plane A and said second pressing means 4 exhibit a corresponding working end inclined with respect of said cutting plane A at a predetermined angle.
  • a recess 29 of said inner end of the body 2 of the sliding element is interposed between the second pressing means 4 and the respective cutting tool 15.
  • the body 2 of the sliding element is equipped with a longitudinal slit 9, placed above with respect to the groove 6 and delimited by a lower plane 7 and an upper plane 8, respectively.
  • the longitudinal slit 9 allows the body 2 of the sliding element to slide and oscillate on the guiding and supporting beam 21.
  • a lower front bridge 10 (Fig. 2) is provided in said body 2 between said lower plane 7 and said groove 6.
  • Lateral external recesses 16 are provided in the body 2 in line with the cutting tools 14, 15.
  • the base plate 17 is equipped with a seat 25 having end notches 26, a layer of elastic material being set into the seat 25 to support the tile 28, P.
  • the base plate 17 is further equipped with transverse graded beams 27 for measuring the distance of the cutting line from the edge of the tile, a square indicator element, not shown, being slidable on said transverse beams.
  • Figures 7 and 8 illustrate a first way of using the device according to the invention, according to which the tile is cut by means of the first cutting tool 15, moving the sliding element 1, 2 from a first position in line with a side of the tile 28 to a second position in line with the opposite side of the tile and pushing the handle 1 towards the tile 28.
  • the "splitting" of the tile 28 is made by means of the second pressing means 4 pushing again the handle 1 towards the tile 28.
  • the recess 29 prevent the body 2 of the sliding element from getting in contact with the surface of the tile 2 before the pressing means 4.
  • Figures 9 and 10 illustrate a second way of using the device according to the invention, according to which the tile P is cut by means of the second cutting tool 14, moving the sliding element from said second position to said first position, in a direction opposite with respect to the previous case, and pulling the handle 1 away from the tile P.
  • the "splitting" of the tile P is made by means of the first pressing means 3, pushing the handle 1 towards the tile P.
  • the inclination of the working end of the second pressing means prevents them from interfering with the surface of the base plate 17.
  • the device may be equipped with a single cutting tool placed between the first and second pressing means, or may be equipped with a single pressing means, placed between the first and second cutting tools.
