Definitions

• the invention relates to a multi-colored patterned floor covering according to the preamble of the first claim.
• Such a floor covering is described in the older, as yet unpublished patent application DE-P 44 05 589.7. It consists of a web that has a first color and of contrasting colored particles that are embedded in the web. The web and the particles are formed from cross-linkable, elastomeric material. The contrast-colored rubber granulate is pressed flush with the surface of the base sheet and permanently fixed by subsequent vulcanization of the structure obtained. The individual, contrast-colored particles have at least two particle sections different in color from one another and from the base track.
• the quantity and color of the particles and particle sections are selected and matched to the quantity and color of the material body forming the web so that the mixed color resulting from a homogeneous mixing of all the constituents contained in the floor covering with the first color matches.
• the object of the present invention is to provide a generic floor covering in which one is more free in the color design. This should open up the possibility of further improving the visual appearance. Furthermore, electrically conductive variants should also be made possible without foregoing colored patterns.
• the invention is based on the following requirements: At least one first particle section must be present, which penetrates at least a second particle section in a wedge or strip shape. If one looks at the visible surface of the floor covering, at least 50% of the particle components visible in the area of the particle components on its surface must each have the same color of the particle sections, which are characterized by their respective surfaces n.
• the taste appearance of the floor covering can be varied by these preconditions to a far greater extent than is possible with the prior art according to DE-P 44 05 589.7: the choice of color is now almost arbitrary and is only subject to taste criteria. This significantly expands the design options, as any color effects can be achieved in the overall impression.
• the particles can be arranged so close together that there is mutual contact.
• the appearance of the floor covering is largely determined by the structure and coloring of the particles.
• the particles are also possible to arrange the particles at a mutual distance from one another.
• the external appearance of the floor covering is largely determined by the color of the web, the particles causing a loosening of the appearance.
• the particles can be distributed in an arbitrarily predetermined pattern, for example also in the manner of letters, words and / or pictograms.
• the contrast-colored rubber granulate is sprinkled in a rubber sheet which is homogeneously colored in a first color. It comprises the particles with at least two particle sections different in color from one another and from the base track. After scattering, the particles are pressed flush into the web using a roller calender, a continuous vulcanization machine or a press at a temperature of 160 to 190 ° C and fixed by subsequent vulcanization of the rubber.
• All elastomeric materials suitable for the production of floor coverings can be used, for example those with the standardized designations SBR, NBR, EPDM, natural rubber and mixtures thereof.
• the contrast-colored granulate based on the color of the web, can be obtained by producing contrast-colored rubber mixtures independently of one another, converting them into strands using extruders, and then granulating them.
• An advantageous embodiment of the present invention consists in that the first particle section comprises at least two sub-sections which extend essentially parallel to one another.
• dirt particles accumulate especially in industrial areas, on drivable floors, but also by walking on them, preferably in a strip-like arrangement. Such deposits are optically particularly well concealed by this configuration.
• This lamination effect is further increased if the first particle section is not straight in at least one point on the strip-shaped course.
• a further advantageous embodiment is that the particles have a smallest linear extension of 12 mm, which is limited by the surface of the floor covering. This means the presence of relatively large visible particle areas, which, particularly in very large rooms, produces a less restless surface effect than numerous small particles do. On the other hand, it is possible to arrange such large particles into pictograms.
• the "smallest linear extension” is to be understood to mean the shortest straight line which connects the two most closely adjacent corners of a particle.
• the floor covering according to the invention can be made electrically conductive, the leakage resistance according to DIN 51 953 being less than 106 ohms.
• the base web accordingly contains soot deposits in a known manner, which color it deep black. Nevertheless, it can be achieved with the present invention that this black color does not dominate on the visible side of the floor covering: there are no limits to the color design, the surface coverage of the base sheet by the rubber granules only insofar as, of course, this covering may only be so dense that The base sheet is always visible on an area of 20 cm at every point of the floor covering, making electrodes electrically accessible.
