Definitions

  • the present invention refers to an improved tool carrier in a manual machine for tile cutting.
  • the manual tile cutters traditionally on the market consist of a base whereon a tile-resting area is provided, wherefrom two end posts project which support one or two guiding bars for the sliding of a tool carrier.
  • Said tool carrier is configured in order to be able to slide freely on the bars and generally has a handle portion and, below, an incision tool (usually comprising a wheel of extremely hard material) apt to engrave the tile.
  • the incision of the tile or of the stone material occurs by applying pressure to the tool on the tile, imparted by the operator through the handle.
  • the base In order to facilitate the subsequent breaking operation, i.e. separation of the tile along the incision line, the base typically comprises a pair of floating plates on both sides of a central, longitudinal, rigid ribbing, arranged in a position sunk in correspondence of the incision line.
  • Manual tile cutters traditionally stand apart due to the fact that they have a single guiding bar or two guiding bars and in the "pull” or “push” types - depending on the tool carrier shape which is intended to perform the incision - while the user pulls it towards himself or pushes it away, respectively.
  • the tool carrier traditionally consists of a main body, whereto the incision tool, the breaking foot and the handle are fastened.
  • the tool carrier body is mounted on the guiding bars with two degrees of freedom.
  • the tool carrier body is free to perform a rotation or pivoting.
  • EP-A1-531916 describes a tool carrier slidingly mounted with a fixed attitude on the guiding bar.
  • this tool carrier is extremely cumbersome to use, for at least two reasons.
  • no adjustment system is provided between the main actuation lever and the breaking foot incision wheel: this prevents adapting the system upon the varying of the thickness of the tiles to be cut.
  • the object of the present invention is hence to solve the problems set forth above, in particular to make the use of the tool-carrier more user-friendly for any thickness of the tile to be incised, at the same time preserving good strength and precision of the tile-cutting machine.
  • a tool carrier in a manual tile cutting machine, comprising a tool carrier body, suited to slide on guiding bar means parallel to the support plane of a base, provided with a lever-shaped handle mechanism, with an incision tool and a breaking foot, said tool carrier body being constrained longitudinally sledge sliding on said bar means, wherein said incision tool and breaking foot are mounted on said tool carrier body sliding crosswise to said guiding bar means, substantially orthogonally to said support plane, and the lever-shaped handle mechanism is pivoted in an articulation point on said tool carrier body and acts on said incision tool and breaking foot, to cause them to slide, on opposite sides of said articulation point.
  • the incision tool and the breaking foot are integral with respective, separated sliders sliding with respect to said tool carrier body and arranged on opposite sides with respect to said articulation point.
  • At least one of said sliders is constrained to a lever of said lever-shaped handle mechanism in an action point through a roto-translation coupling means.
  • at least one of said sliders has a small shelf with which the end of an adjusting screw - integral and adjustable on a lever of said lever-shaped handle mechanism - engages.
  • the slider integral with the incision tool has a nib apt to arrange a point of action of said lever of the lever-shaped handle mechanism away from said articulation point.
  • the point of articulation is arranged on said tool carrier body in a position opposite to said base with respect to the bar guiding means.
  • the tool carrier body has at least three bearing means apt to define at least three sliding bearing points on the opposite edges of said guiding bar means.
  • a manual tile cutting machine comprising a base wherefrom posts for the fastening of guiding bar means rise, wherein the tool carrier is as described above.
  • Figs. 1-9 exemplifyingly show a single-bar manual tile-cutter with a rectangular-section bar.
  • the machine consists - in a way known per se - of a base 1 whereon a pair of support plates 2 is floatingly installed.
  • Bar B is typically a thin, elongated steel plate, having a rectilinearity and parallelism of the two opposite sides suited to act as precise guide for a tool-carrier P which must slide parallel to base 1.
  • tool-carrier P consists of a series of elements, mutually movably connected, which will be described in further detail in the following.
  • a main body 4 is configured to slide precisely along bar B.
  • body 4 has a cavity or through-pocket, which runs longitudinally through it, within which bar B is intended to slide.
  • body 4 has two opposite jaws between which a gap is defined wherein bar B can slide.
  • the through-pocket is run through transversally by bearing means which rest sliding or rolling on the two lower and upper edges of bar B, so as to allow body 4 only a longitudinal sledge movement.
  • Such bearing means can be shaped - as illustrated - as simple cylindrical pins, locked on body 4 by means of tightening bolts 5, screwed on threaded ends of the pins coming out externally from body 4.
  • the pins can be borne directly on the lower and upper edges of bar B, or are preferably provided with brasses or rolling bearings 5a by which they rest on the bar edges.
  • said bearing means are preferably at least three, so that there are three sliding support points and the structure is statically determinate.
  • Sliding body 4 furthermore carries an articulation pin 6 whereon a lever 7 is pivoted, provided with a handle 8 apt to be manoeuvred with one hand by the operator.
  • Lever 7 is hence mounted freely pivoting about said articulation point 6 arranged in a fixed position in the upper part of sliding body 4.
  • articulation point 6 lies above bar B, so that lever 7 can be arranged on the same plane as bar B, pivoting within the pocket of body 4, without creating interferences.
  • two sliders 41 and 42 are furthermore mounted, a forward one and a rearward one respectively, with respect to the progress direction of the tool carrier on bar B, i.e. on opposite sides with respect to an axis orthogonal to the progress direction and passing through articulation point 6.
  • the two sliders 41 and 42 are mounted on sliding body 4 so as to be guided along a rectilinear movement substantially transversal to the longitudinal axis of bar B, i.e. perpendicular to the support plane of the base 1 whereon the tile to be incised is placed.
  • This rectilinear movement causes the two sliders to move closer together and apart from the below-lying tile when it rests on the plane of base 1, i.e. on floating plates 2.
  • front slider 41 i.e. on the left hand side in fig. 3
  • Rear slider 42 carries instead - at the lower end (i.e. the end opposite lever 7 with respect to bar 8) - a breaking foot 10.
  • incision tool 9, nor breaking foot 10 will be described here in further detail, since they are widely known to a person skilled in the field.
  • sliders 41 and 42 The sliding mounting of sliders 41 and 42 on sliding body 4 can be defined as best preferred.
  • the two sliders 41 and 42 have a rectilinear sliding plane coupled with respective planes of the front and rear edges of body 4.
  • On each slider grooves or rectilinear slits 43 are furthermore made, wherein the shaft of an Allen screw 44 is inserted, fastened to body 4, which allows a sliding between slider and body 4, but maintains the transversal coupling.
  • Each slider is fork-shaped, so as to have two prongs, on both sides of bar B, and a root portion whereon incision tool 9 and breaking foot 10 are respectively installed.
  • the two sliders 41 and 42 are driven in their vertical sliding travel (or in any case orthogonal to the longitudinal axis of bar B) by lever 7, which acts thereon on the two opposite sides of articulation point 6.
  • lever 7, which acts thereon on the two opposite sides of articulation point 6.
  • the rotation of lever 7, obtained by acting on handle 8 is capable of moving the two sliders along opposite directions: a lowering of front slider 41 is synchronised with a raising of rear slider 42 and vice versa.
  • the vertical translation movement of breaking foot 10 is useful to keep the foot raised from the tile, in the incision phase, and to then lower it by pressure when the tile is to be broken.
  • the vertical translation movement of the tool serves - in addition to progressively moving the tool closer to the tile - especially to adjust the height position of tool 9 to the thickness of the tile being incised.
  • slider 41 preferably has a front nib 41a at the front end of which a pin 41b is arranged for engagement with lever 7, by which said lever is apt to impart the necessary lowering or raising force on slider 41. If pin 41b is stationary on nib 41a, lever 7 engages therewith through a slit 7a ( fig. 5 ), to allow the relative roto-translation movement of lever 7 with respect to slider 41.
  • slider 42 carrying breaking foot 10 has a small shelf 42a, whereon the end of an adjustment screw 11 integral with lever 7 acts.
  • an adjustment screw 11 integral with lever 7 acts.
  • the upward return (or the moving away from the support plane of the base) of slider 42 can be guaranteed by an elastic element (not shown) which acts between body 4 and slider 42.
  • Adjustment screw 11 has the valuable function of allowing to establish the desired inclination of handle 8 in conditions of equilibrium, which each operator can adjust at will.
  • Fig. 6 shows a tool carrier according to the teaching reported above, wherein four guide points 5 are provided, instead of three, between sliding body 4 and bar B.
  • Figs. 10A and 10B show another embodiment of a tool carrier according to the invention.
  • sliding body 400 is conceived to slide on two parallel, cylindrical bars C 1 and C 2 , arranged side by side on a horizontal plane, i.e. parallel to the support plane of the base.
  • both points of action 141b and 142b of lever 7 on the sliders of the tool and of breaking foot 141 and 142 comprise a roto-translation coupling (bolt inserted in an elongated slit).
  • Figs. 11A and 11B show a further variant of the device according to the invention.
  • the guide bars are shaped as two parallel, cylindrical rods G 1 and G 2 , arranged one on top of the other on the plane orthogonal to the plane of base 1 and passing on the incision line.
  • the sliders of tool 9' and of breaking foot 10' are arranged on the two opposite sides of body 400'.
  • the two sliders are still shaped as forks, but the two prongs embrace the entire sliding body 400', rather than the sole guide bar B as in the first described embodiment.
  • the two sliders are furthermore constrained to lever 7' similarly to as described for the second embodiment. For the rest the elements and the operation are fully similar to those described for the embodiment of figs. 10A and 10B .
  • the tool carrier according to the invention allows to fully achieve the desired object, i.e. to obtain good sliding precision, reducing pivoting angles and hence the rotation values of the handle regardless of the thickness of the tile to be incised.
  • the points of action of the lever on the sliding sliders can be both provided with a support between a shelf and an adjustment screw, or provided with further and diverse means.
