DETAILED DESCRIPTION OF THE INVENTION

The invention relates to a decorative component which has at least one grate element or is made from a grate, characterized in that at least one and preferably all grate meshes of the grate element or grate are filled with a hardened synthetic resin or a silicone rubber. A "grating mesh" is understood to mean the area which is obtained by multiplying the mesh size 3 times the mesh size 4 (cf. FIG. 5). Non-rectangular rust meshes are the corresponding area.
A “grate element” is understood to mean a grate that has at least four grate meshes.

Either components are used to produce the decorative component, which have a grate element or it is a grate as a central component went out.

The grate elements or grids are made of metal, plastic or wood. Many gratings that are already commercially available are suitable as a central component for producing the component according to the invention. Industrial gratings, universal gratings, grating steps (see FIG. 1), comb gratings, air source gratings or (plastic-coated) rolling gratings can be used. Such grates have previously been used, for example, as ventilation grilles or as covers for shafts and channels and have been used in heating, ventilation or stair construction.
The metal gratings can consist of any metals and alloys used in house and furniture construction. Examples include steel, stainless steel or chrome steel, brass and aluminum.
In particular, hot-dip galvanized standard gratings (see FIG. 2) made of cold-rolled steel strip (for example St 37 or K 60) or gratings made of chrome steel are suitable. If required, such grids are specially or plastic-coated, lacquered or bituminized accessible. FIG. 3 shows the structure of a standard grating composed of composite bars 1 and supporting bars. 2.
In addition, aluminum gratings in a wide variety of embodiments are suitable for producing the component according to the invention. Aluminum grates are available in various RAL colors, stove-enamelled. FIG. 4 shows various commercially available aluminum linear gratings.
The grates mentioned above are sold, for example, by Seppeler Group Neuhaus, Helling & Neuhaus, Gütersloh, Germany or Ado-Metall GmbH, Geeste-Dalum, Germany.

The size of the grate mesh of suitable grates depends on the desired one Area of application and the aesthetic requirements. With little stress Components can vary the size of the grate mesh in a wide range against, whereas the size of the grate meshes with loaded components the desired degree of exposure is limited.

The majority of the grids commercially available have rectangular or square stitches. For grates with rectangular grids, between A distinction between mesh size 3 and mesh size 4 (see FIG. 5). to However, grids are also suitable for producing the components according to the invention any mesh shape, for example gratings, the rust meshes of which have a rhomboid, Form a rhombus or trapezoid. The invention also includes grids with triangular Rust meshes such as equilateral and non-equilateral triangles and polygons such as Example honeycomb. In addition, the rust meshes can be round, oval or elliptical be designed. FIG. 6 shows preferred forms of the rust mesh.

The border 5 (see FIG. 7) of the metal grids 6 and their thickness depend on desired field of application and will be approved by a specialist in individual cases established. Suitable edging (see FIG. 6) are, for example, as Flat profile 7, T profile 8, U or C profile 9, angle profile 10, H profile 11, Z profile 12 or designed as a hollow steel profile 13.

The shape of the decorative component can be freely chosen according to the structural and aesthetic requirements.
If the decorative component is constructed from a grate as a central component, its shape results from the shape of the grate selected.

Rectangular or square metal gratings are suitable for many applications, In addition, grates with other geometric shapes such as trapezoids, Rhomboids, rhombuses, equilateral and equilateral triangles, Pentahedra, hexahedra and other polygons can be used. The grates can also form circles, semicircles, ovals or ellipses. Figure 8 shows preferred forms of gratings.

Plastic gratings that are used to manufacture the component according to the invention suitable, consist for example of (isophthalic acid) polyester, vinyl ester / epoxy resin or phenolic resin and are optionally glass fiber reinforced. Figure 9 shows one Section from a well-known plastic grate. Plastic gratings are in various qualities commercially available (e.g. from Seppeler Group Neuhaus, Helling & Neuhaus, Gütersloh, Germany or at Maag Technic AG, Dübendorf, Switzerland.

The size and shape of the grids and their grate meshes as well as the edging The plastic gratings can be made in analogy to the above-mentioned metal gratings be determined by the expert.

Wooden gratings are made of soft or hardwood or of softwood or hardwood made (for example oak or basra). The size, strength and shape of the Rust meshes as well as the edging and the shape of the wooden gratings can be in Analogy to the above-mentioned metal gratings determined by the expert become. Wooden gratings are, for example, from Ado-Metall GmbH, Geeste-Dalum, Germany available. However, they are also suitable for carrying out the invention Type cases, which are commercially available in various designs are. Commercially unavailable wooden grates can be made by a carpenter made to measure.

For the production of the decorative components according to the invention, that is to say for pouring out the rust mesh of the above-mentioned rust elements or grids, known, optionally colored synthetic resins or silicone rubbers are suitable which have hitherto been used, for example, as embedding resin, adhesive resin or laminating resin. The hardening of the liquid resins is brought about by the addition of chemical compounds (hardener, accelerator, catalyst), which usually leads to heating of the mass and converts it from the liquid to a solid state (e.g. condensation or addition crosslinking). The resins are preferably cured at room temperature and at atmospheric pressure and are optionally followed by tempering, by means of which the hardness and strength of the resin can be further influenced. In addition, curing can also take place in warm (30-100 ° C) or heat (100-200 ° C).
Suitable synthetic resins are thermosets such as epoxy resins,
Polyester resins, polyurethane resins or vinyl ester resins or elastomers such as silicone rubber (available from R. & G. fiber composite materials, Waldenbuch, Germany).

Gless resins based on polyester that are liquid at room temperature are preferred or epoxy.

The epoxy resins usually contain bisphenols and epichlorohydrin. The use of a bisphenol A / F resin is particularly suitable.
Suitable hardeners, which are used with epoxy resins, are known and, in case of doubt, tried and tested resin / hardener combinations can be used. Preferred hardeners contain mixtures of aliphatic and cycloaliphatic di- and polyamines.

Unsaturated polyester casting resins which have as many of the following properties as possible are particularly preferably used: low viscosity, medium reactivity, crack resistance, great stability against light and crystal-clear curing.
As an example of a resin that meets these conditions, cobalt pre-accelerated orthophthalic acid polyester resin can be mentioned. Methyl ethyl ketone peroxide (MEKP) is preferably used as the hardener for this resin, which has optionally been phlegmatized with dimethyl phthalate.
The resins and hardeners described above are available, for example, from R. & G. Faserverbundwerkstoffe GmbH, Waldenbuch, Germany.

If necessary, the decorative component becomes after the resins have hardened Removal of residual volatile components in the resin (especially residual styrene content) post-cured for one to several hours at elevated temperatures. 1-74 are suitable Hours at 40-120 ° C, especially 6-12 hours at 50-90 °, especially preferably about 10 hours at about 60 ° C. The so hardened and Steamed out components are harmless to health and food law and can be used in the living area.

Organic or inorganic dyes or pigments which are known to the person skilled in the art for this purpose are suitable for coloring the synthetic resins.
Transparent colors or pigment color pastes (for example epoxy color pastes or Pintasol colors) are preferred, of which the pigment color pastes are available in many different RAL colors and are sold, for example, by R. & G. Faserverbundwerkstoffe GmbH, Waldenbuch, Germany. Transparent colors are particularly preferably used, which permit transparent or partially transparent coloring of the resin.
Transparent colors in bright colors are sold, for example, by DEKA GmbH, Unterhaching, Germany.

The optical and / or physical properties of the resins can may be influenced by additives. To achieve special The expert can select effects from a wide range of additives, which does not prevent the use of the resins according to the invention. Possible additives to influence the visual appearance of the rust hardened resin compartments are, for example, glass chips, thixotropic agents, Cotton flakes, glass bubbles, sand, aluminum, graphite, or copper powder. The Fillers can be spherical, rod-shaped or platelet-shaped. You can also Figures or objects are poured into the resin as examples can be wood, stones, plaster, plastic, coins, flowers, photos, letters, insects or called mussels. These natural, plastic, wood, or metal existing objects can be completely or partially cast into the resin his.

For the production of components which are exposed to strong weather conditions are (for example railings or tread elements) the treatment of the colored resin layer with an unsaturated polyester (UP) pre-gel (gel coat) or an epoxy gelcoat. Such transparent fine-layer resins ensure an optimally homogeneous, UV-resistant outer layer.

The components according to the invention can be manufactured as follows (see FIG 10): A flat hard plate 14 (for example made of wood, stone, metal, plastic, Glass or the like), the dimensions of which are larger than those of the component to be manufactured is covered with a soft material 15. The soft material can be, for example, a woolen blanket, a strong cotton cloth, a Flow mat, a fur, a foam mat (such as polyethylene foam roll or Polyethylene profile foam board), a neoprene, Novilon, rubber, latex or Cork mat or the like. On this soft material 15 is a solvent-resistant (solvent-resistant) plastic film 16 or a polyethylene bubble wrap 16 laid. The grate 17 is pressed onto this arrangement (for Example using screw clamps), so that the individual rust meshes through the underlying plastic material are sealed and the resin after the pouring out the rust mesh does not leak. The minimum pressure required for this depends on the viscosity of the synthetic resin or silicone rubber to be used, the Rust material and the base and can easily be determined by a specialist become.

The casting resins to be used are carefully mixed with the respective hardeners or activators in a vessel, colored if necessary in the desired color and optionally mixed with further additives. If necessary, the resin can also be colored before the hardener or activator is added, and the additives can be added directly to the rust mesh if required. The prepared resin is poured into the individual rust meshes. The resin is then allowed to harden.
The synthetic resin or silicone rubber thickness, ie the height at which the rust meshes are filled with the synthetic resin or silicone rubber, can be varied, the individual compartments having to be filled at least to such an extent that the entire surface of the individual rust meshes is covered. The maximum fill level of the resin is at the upper edge of the edge of the grate. Depending on requirements, the person skilled in the art can choose the desired resin strength between these extreme values. The minimum thickness of the resin layer is at least 0.2 mm, preferably at least 1 mm and particularly preferably at least 2 mm.

In the manufacture of a single-color component, all rust meshes are poured out with synthetic resin or silicone rubber of the same color, the additives which may be present for individual subjects being the same or different.
To produce two-colored or multi-colored components, the rust meshes are poured out with different-colored synthetic resin or silicone rubber, the additives which may be present for individual subjects being the same or different. At least one rust mesh, but preferably all Rosff meshes are poured out.

After curing the resin (completely or partially), which depends on its composition lasts between a few hours and a few days detached and turned the component from its base, the plastic or the bubble wrap 16 usually sticks to the resin. The plastic or the bubble wrap 16 is carefully peeled off the resin, whereupon obtained decorative component if necessary at an elevated temperature can be cured. Figure 10 shows a grate section with a poured grate mesh 18.

The surface of the resin can be softer by using different ones Materials 15 and different plastic films / bubble wrap 16 influenced become. The use of a particularly soft material 15 (see FIG 10) a greater curvature of the resin surface than a harder base. In addition, the surface of the resin through the plastic film / bubble wrap 16 to be influenced. For example, an air cushion film instead of the plastic film used, the usually slightly curved surface of the resin due to the Blowing the bubble wrap also small dents. Are bubble wrap For example, made of polyethylene and have bubbles with a diameter between 10 and 30 mm. Such bubble wrap films are available, for example at Medewo, packaging material, Meisterschwanden, Switzerland.

In addition, the surface of the resin can be influenced by the fact that between the soft pad 15 and the solvent-resistant film 16 small objects be placed (e.g. plastic chips). The choice of these objects is not critical, as long as they don't seal the rust mesh on the underlay render impossible. When using such objects, it makes sense to use the Plastic film 16 to cover the plate 14 and the soft material 15 and this Evacuate structures.

EXAMPLE Production of a decorative component

A rigid, flat wooden board 14 with a smooth surface (2 mx 0.6 mx 25 mm) was placed on a flat table and covered with two layers of a wool blanket 15 and a layer of solvent-resistant plastic film 16 (approx. 3 mx 1 mx 0.2 mm). A grid 17 made of hot-dip galvanized structural steel (St. 37, 1.8 mx 0.35 m, edging with a U-profile, mesh size 0.05 m,
Mesh division 0.05 m, thickness of the support bars 25/2 mm, thickness of the composite bars 10/2 mm, Seppeler Group Neuhaus, Helling & Neuhaus, Gütersloh, Germany) was fixed by means of screw clamps and wood additions and it was visually checked that all rust meshes were properly sealed.

Preparation of the casting resin (the percentages refer to Weight percent): 3 kg of a polyester resin (UP Giessharz Glasklar, R. & G. Faserverbundwerkstoffe GmbH, Waldenbuch, Germany) were combined in one Metal container with 1 - 2.5% MEKP hardener (resp. Resin, R. & G. fiber composite materials GmbH, Waldenbuch, Germany) and carefully mixed. To this The mixture was 0.3% transparent color light blue (or resin, color from the company DEKA) added.

The colored resin prepared in this way was poured into the individual grating meshes of the grating up to the upper edge of the composite rods 1 (10 10 mm) and left to harden for about 10 hours.
The hardened resin layer had a flat, smooth, glossy surface, which was flush with the composite rods 1 and was overtopped by the support rods 2 and the border 5.

The component was then detached from the base and turned over, the Plastic film 16 remained on the almost completely hardened resin. The Plastic film 16, however, was easily peeled off from the hardened resin, whereby this Process led to a slight structuring of the resin surface. The Resin surface in the individual rust mesh pointed next to the said Structuring a slight bulge. This curvature is due to the pressure of the Blanket 15 and the plastic film 16 on the individual rust mesh due.

The component was then used to remove the residual styrene content 10 Cured for hours at around 60 ° C.

The resin surfaces of the component were then gloss-sealed on both sides with a polyurethane varnish.
The light blue, partially transparent component thus obtained met the highest decorative requirements and was used as a side wall in the manufacture of a shelf. The part of the support rods 2 of the decorative component protruding from the resin (see FIG. 11) served as holders for the shelves of the shelf.
