Description

The invention relates to a tile cutting machine according to the preamble of claim 1, such as for cutting or trimming tiles, in particular used by tilers.

Tile cutting machines have been known for a long time and they exist in general from a rectangular, relatively elongated machine plate, on one of which A vertically swiveling cutting rail is fastened in the middle on the narrow side, on which a cutting arm is arranged to be longitudinally displaceable. On the other narrow side is a longitudinal stop bar attached.

For example, a tile cutting machine is known from US Pat. No. 2,568,816, in which a The scale ruler is embedded in the machine plate so that it can be moved. On one At the end of the scale is a stop angle over an arcuate slot and The screw can be swiveled and thus fixed in an angle-adjustable manner. The exact Angle adjustment of the stop angle is not easily feasible because corresponding settings are not provided. Is also an accurate one Cutting small and large tile slabs, alternating between longitudinal and Diagonal cuts, not possible without more complex shifting and adjustment work.

In addition, the "purchasing consultant" catalog III / 96, pages 2 and 3, of the company Karl Dahm, remove a tile cutting machine, the stop bar, the top Assigned inside edge, has a centimeter scale while in the last surface a slide-in ruler that can be moved to the machine plate is. At one of the ends of the slide-in ruler, a guide rail or a Oblique and diagonal cut stop e.g. be attached interchangeably. The machine plate is usually 25 cm wide, so when cutting large format tiles a side arm must be used, especially around the side stop serving guide rail, with the one pushed beyond the machine width Support the condition in terms of height, otherwise it will sag and can no longer serve as a side stop. Should now be a stripe from a tile cut certain width, the tile on the machine plate is like this to lay out that the corresponding edge with respect to that serving as a measuring ruler Longitudinal stop bar with scale according to the desired dimension with raised Cutting rail is placed, after which the cutting rail is lowered and the cut is made. The scale attached to the metal stop bar is not, especially after a certain period of use of the tile cutting machine more optimally readable and also the lines and labeling relatively small, see above that a tiler of advanced age to put on or adjust exactly the guide rail over the slide-in ruler, put on his reading glasses. On the fast one single plate without guide rail to exact centimeter dimensions cutting is not optimal. The use is also always with 45 ° cuts a corresponding stop is necessary, which instead of the guide rail to be ordered. Should quickly only a small number of tiles in between cut to 45 °, this is not possible because first a rail or Stop exchange must take place.

The object of the invention is a tile cutting machine o.g. To specify genus which is an exact cutting of small and large tile slabs, in quick Alternation of longitudinal and diagonal cuts allowed in a simple, optimal way.

This task is accomplished by a tile cutting machine with the distinctive Features of claim 1 solved. Further advantageous configurations are in the Subclaims marked.

Accordingly, there is a rectangular alignment plate on the surface of the machine plate attached, which has a line grid on its upward-facing surface. Thus, a tile can now correspond to the line grid of the alignment plate can be quickly aligned and cut.

It is advantageous if the line grid of the alignment plate consists of a longitudinal line grid from parallel to each other longitudinal and transverse lines and from a diagonal grid with 45 ° lines. The longitudinal lines can preferably be in one Distance of approx. 1 cm and the transverse lines at a distance of approx. 5 cm, while e.g. the diagonal grid lines are about 2.5 cm apart exhibit. Of course, a narrower or wider line grid can also be used can be used, however, especially for the longitudinal line grid a line spacing of 1 cm is best proven. The tiles can now can be quickly and precisely aligned and cut so precisely.

It is also advantageous if one on one of the narrow sides of the alignment plate Centimeter scale is applied symmetrically, being from the center of the alignment plate outgoing, on both sides, assigned to the longitudinal lines of the line grid, ascending numbers are applied. Especially for the arrangement of the Alignment plate on the machine plate is there before or during fastening on the machine plate particularly favorable if the central longitudinal line as "Zero" longitudinal line, much more executed or introduced than the rest Longitudinal lines. This ensures that when the alignment plate is worn out new alignment plate quickly and at the same time dimensionally correct to the scale of the stop ruler and is attached to the cutting rail or cutting arm at the same time. The new alignment plate is placed on the machine's stop bar and then simultaneously along the longitudinal lines according to the scale of the stop bar of the line grid, in particular precisely aligned over the central zero longitudinal line and attached.

In order to be able to work particularly quickly and precisely, especially when working continuously changing cuts, is advantageous when different colors be used, e.g. for the grid lines and the fields formed by the lines. For example, the longitudinal lines are colored differently, e.g. alternately be colored differently or each have a different thickness or Have width so that the even-numbered lines differ from the odd-numbered ones Have lines well differentiated. This allows you to quickly determine a centimeter can also be carried out for somewhat poorer sighted people without one Glasses must be put on.

Due to the different color design of the formed by the longitudinal lines Longitudinal fields, e.g. in 2-color design in alternating succession a different coloring of the longitudinal fields can be provided. For example, alternating white fields with gray fields, a pleasant stripe pattern yielding.

A particularly good distinguishability of the grid lines from each other and at the same time an optimally precise alignment of the tiles to be cut is e.g. receive, if a gray-white longitudinal stripe, each with 1 cm wide longitudinal field interpretation, also on 5 cm spaced, thicker transverse lines and finally a red-line diagonal grid with a grid dimension of 2.5 cm is provided. Of course is the respective center line of the longitudinal-transverse grid for better and Faster recognizability, correspondingly reinforced-strengthened or double-line.

According to the invention, the alignment plate can have the same width as the machine plate, namely usually a total of 25 cm. The grid longitudinal lines assigned narrow-sided centimeter scale, each from the center in their figures outgoing, is then 12.5 + 12.5 cm.

It is particularly advantageous if the alignment plate is wider than the machine plate, preferably twice as wide, e.g. 50 cm wide. This also allows large format Tiles rest securely and also the guide rail that serves as a cross stop always lies correctly on the alignment plate along its entire length, so that also the respective cross stop can always be used optimally. The oblique can also Diagonal cut stop can be quickly set to 45 °.

According to the invention, the alignment plate can be in various ways on the machine plate be attached. So the alignment plate can be directly on the top of the Machine plate or on an intermediate plate that can be attached to the machine plate be applied and in each case quickly removable, without being destroyed be, or so that when a used plate is removed appropriately, this is destroyed at the same time.

The alignment plate can be made of different materials and different Be formed or designed thickness.

So the alignment plate can be made of cardboard. If a relatively thin box is used, this can e.g. glued directly onto the machine table with wallpaper paste become. If necessary, it can then be soaked and peeled off for removal or scraped off. Even when using a thicker box than Alignment plate there is the possibility of fixing with wallpaper paste and then Peel off. However, it can also be a double-sided tape attachment be provided or an overall self-adhesive underside can be used.

The alignment plate can also be made of different thickness plastic material, e.g. one Plastic plate or a film, also a self-adhesive film with applied lines, be made. However, a metal plate, in particular a sheet metal plate, can also be to be used, where there is a possibility on the top to carve or engrave the lines and also color them. Such The plate also has a correspondingly long service life.

If the alignment plate is made of relatively thin material, e.g. provided relatively thin cardboard and, especially for the double-width version, an intermediate plate used, on which the cardboard alignment plate is applied, this intermediate plate also be made of different materials and can also be releasably attached to the machine table in various ways.

So the intermediate plate, which can preferably be about 4 mm thick, from one correspondingly thick cardboard, sheet metal, wood, plastic or any combination of materials be made. It can e.g. over a double-sided tape, one self-adhesive bottom, by known clamping devices or Magnetic devices are releasably attached. In the case of magnetic attachment are in advantageously embedded in the top of the machine plate while magnets on the underside of the intermediate plate (or the alignment plate for direct Attachment of the alignment plate) according to metallized zones or sheet metal strips or sheet metal plates are to be provided, unless the entire plate consists of ferromagnetic material.

The invention is explained below using an exemplary embodiment with reference to the drawing explains in more detail.

As can be seen in particular from FIGS. 1 and 2, there is a tile cutting machine essentially of a rectangular machine plate 1, which at its Bottom with feet 2, which are preferably designed as four rubber feet is.

On the narrow side of the machine plate 1 as shown in the drawing, there are over one Fastening rail 3 and in the middle of it, projecting outwards in the longitudinal direction, a swivel bracket 4 attached to which one in the longitudinal direction over the entire length of the machine plate extending cutting rail 5 hinged vertically is. For easier handling of the cutting rail is on the outer End of a handle 6 attached. On the cutting rail 5 is a cutting arm 7, along of the entire working area of the machine, arranged longitudinally.

A longitudinal stop bar 9 is located on the second narrow side of the machine plate attached, the one on their inwardly facing upper edge section Centimeter scale 10, the numbering of which is symmetrical from the center, i.e. at the same time not from the center of the cutting rail or the cutting arm shown cutting knife, is provided, ie from the center "0" in each case to both Pages rising by the centimeter. In the top of the stop bar 9 is a Insert ruler 11, slidable to the machine plate, embedded. It points also on its top a scale 12. It also carries over one of its outer ends of a guide rail extending in the longitudinal direction of the machine plate 13, which can be replaced by a bolt 14 on the slide-in ruler 10 is attached.

On the machine plate 1, as can be seen in particular from FIG. 2, via a An alignment plate 15 is attached to the intermediate plate 16. The two plates 15 and 16 are connected to each other or to the machine plate 1 via adhesive dots 18 or 17. As already described, only the intermediate plate 16 can be releasably attached connected to the machine plate 1, e.g. via removable adhesive dots 17 such as double-sided adhesive strips or also a magnetic device, while the alignment plate 15 either also detachable via e.g. Glue dots 18 connected to the intermediate plate 16 is or e.g. is glued to this over wallpaper paste, which in the latter In the event of detachment, the plate 15 is destroyed.

In the example shown in FIG. 1, the alignment plate 15 and, if appropriate, the alignment plate Intermediate plate 16, designed in double width, i.e. the width of the alignment plate 15, or the plates 15 and 16 is twice as large as the width of the machine plate 1.

3, is on the top of the alignment plate 15 applied a longitudinal grid 20 that consists of longitudinal lines 21 and 22 cross lines. The middle longitudinal line is reinforced as the zero line 23, and so is the middle cross line is recognizable as center line 24 different from the other cross lines educated.

In addition to the longitudinal grid 20, there is a 45 ° diagonal grid on the surface of the alignment plate 15 30 provided, consisting of at right angles to each other Diagonal lines 31 and 32. These diagonal lines are what is not in the drawing can be represented, e.g. designed in red color, while the lines of the longitudinal grid 20 are laid out in black.

On one narrow side of the alignment plate 15 is a scale 28 in the manner of a ruler applied, the scaling of which is aligned with the zero line 23, that is to say the numbers 29 are starting from the zero line 23, each with increasing amounts of numbers applied.

The fields formed between the longitudinal lines 21 of the longitudinal grid 20 are successive, i.e. alternating colors. This changes e.g. each a light field 25 with a dark field 26, e.g. a gray one Field or any colored field can be.
