Definitions

  • the invention relates to a tile cutting device, with a base plate designed as a tile support and with a slide which can be displaced on a horizontal guide above the tile support and on which an angle lever having a cutting wheel, a breaking head and an actuating arm is pivotably mounted.
  • tile cutting devices are known in numerous embodiments. In order to be able to cut oversized tiles and other large slabs, such tile cutters are built relatively long and large, which inevitably makes them expensive and heavy.
  • the object of the invention is to achieve a material and weight saving and thus a cost reduction in such tile cutting devices without impairing the manageability and functionality.
  • the invention provides that the horizontal guide is arranged off-center near a longitudinal edge of the base plate and that only the part of the base plate lying on the opposite side of the cutting wheel path is approximately hand-wide. These measures result in a considerable reduction in the dimensions of the base plate compared to the known devices in which the horizontal guide is arranged above the longitudinal center of the base plate. Since the base plate generally consists of die-cast and, in the main, makes up the weight of the tile cutting device, the invention can achieve a total weight saving of up to 25%. The functionality of the device is not affected in any way, because the reduction of the floor area is irrelevant for the stability of the device, since neither the cutting or scoring of the panels nor the subsequent breaking of the panel places special demands on the stability of the device.
  • the invention makes use of the knowledge that the base plate - apart from being a bearing for the upper guide - is in itself only used as a tile support on which the tile must be held with one hand when cutting or scoring. Since only one hand is available for this hold on anyway stands, since the carriage has to be moved with the other hand, it is sufficient if there is only a sufficiently wide support surface for the tile and a hand to be placed on the tile on one side next to the cutting wheel path.
  • a further weight saving can be achieved according to the invention in that the bottom plate on its side facing away from the guide is shorter than the guide.
  • the base plate can be rounded, beveled or stepped at its corners facing away from the guide.
  • the base plate preferably has an approximately trapezoidal plan, the longer trapezoidal base lying on the side of the guide.
  • the roundings, bevels or gradations of the base plate can advantageously extend up to approximately the stop bar.
  • the base plate consists of a die-cast plate that is only a few millimeters thick and has a pulled-down stand edge, which on its underside by transverse ribs and on its top by the stop bar and by a tile breaking bead extending along the cutting wheel path is reinforced.
  • the guide can consist of two parallel steel rods, which are held in bearing blocks at the ends, and the slide can consist of a closed rectangular frame lying between the two steel rods, which is penetrated by the working arm of the angle lever and which is attached to its four Corners is provided with guide eyes running on the rods.
  • the carriage which can be made of die-cast or plastic, is given a very high stability by its design as a closed frame, which on the one hand makes it possible to build the carriage itself relatively thin-walled and light. It is even more important, however, that the carriage can be made relatively short and narrow because of the elimination of any risk of canting or twisting, with the result that the two guide rods can also be arranged relatively close to one another. This in turn has the consequence that the end supports can be dimensioned correspondingly narrow and that the part of the base plate lying under the guides can also be kept much narrower.
  • the crusher head is rigidly arranged on the working arm and - seen in side view - circular arc on its underside is curved in shape.
  • the working arm of the angle lever can consist of an arcuate casting body concave towards the actuating arm and the crusher head can be integrally formed on the lower end of the arcuate casting body on the side facing the actuating arm Base plate molded-on ridges are screwed. All of these features serve on the one hand to achieve a device which is stable in itself, but on the other hand also lightweight, which can be carried easily by the handyman or handyman.
  • the tile cutting device illustrated in FIGS. 1 to 3 has a base plate 1 of approximately trapezoidal plan, bearing blocks 2, 3 on the base plate 1 being screwed on by means of the screws 4 on the widely spaced - in the drawing rear - corners.
  • the bearing blocks 2, 3 have a base leg 5, which is provided with an elongated hole 6 for receiving the fastening screw 4.
  • the bearing blocks 2, 3 are each closely bordered between two stop webs 7/8 formed on the base plate 1
  • the bearing blocks 2, 3 carry two parallel guide rods 9, lo, which are advantageously round steel rods.
  • a slide 11 is slidably arranged, which has a self-contained, rectangular frame 12 (see also FIG. 6), which lies between the two guide rods 9, 10 and which is at its four corners with the guide rods running guide eyes 13, 14, 15, 16 provided
  • On the long sides of the rectangular frame 12 are two lugs 17, 18 aligned with each other, in which the axis 19 of an angle lever is mounted, which consists of an actuating arm 20 and a working arm 21 (see also FIG. 7).
  • the working arm 21 is designed as a bridge arch and its concave side 22 is directed towards the actuating arm 20.
  • the working arm 21 carries a cutting wheel 24 at the corner facing away from the actuating arm and a crusher head 25 at its corner on the side of the actuating arm.
  • the crusher head 25 is rigidly formed on the working arm 21 made of die-cast or plastic and has a side view 7 seen - an arcuate bottom surface 26th
  • the slide 11 and the working arm 21 are located exactly in the middle between the guide rods 9, 10, and a tile breaking bead 27 is formed on the base plate 1 and lies exactly below the cutting path of the cutting wheel 24.
  • the base plate 1 On both sides of the tile crushing bead 27, the base plate 1 has soft rubber pads 28, which advantageously protrude slightly above the crushing bead 27.
  • the base plate 1 has on its upper side a transversely directed stop bar 29, interrupted in the extension of the breaking bead 27, for engaging a tile 30 to be cut.
  • the base plate 1 consists of a thin-walled, advantageously approximately three mm thick die-cast part, which has a pulled-down standing edge 31 and a network of reinforcing ribs 32.
  • the path of the cutting wheel 24 - which coincides with the breaking bead 27 in plan view - is off-center near the longitudinal edge 33 of the base plate 1, which here forms the larger trapezoidal side.
  • Opposite is an approximately hand-wide, e.g. Eight to nine millimeters large distance between the smaller trapezoidal side and the breaking bead 27 is provided, which is sufficient for supporting and holding a tile 30 completely.
  • FIG. 4 shows an embodiment with rounded corners 34
  • FIG. 5 shows an embodiment in which the base plate at these corners is formed by right-angled corner recesses 35 is graded.
