Description

description

The invention relates to a demountable outdoor floor covering, in particular an outdoor sports floor covering according to the preamble of patent claim 1.

Such an outdoor floor covering is disclosed, for example, in WO 201 1/090499 A1.

This floor covering consists of a plurality of floor elements, which have approximately a rectangular base surface and at the abutting edges of the fitting elements are formed, which correspond with corresponding fitting elements of the adjacent

Floor element cooperate in the sense of locking or centering. These fitting elements may be integrally formed on the bottom element. The connection or centering can alternatively or additionally be done via locking elements that connect adjacent floor elements non-positively or positively. The floor elements made of plastic form a subfloor on which a cover layer can be laid, which in turn consists of approximately rectangular floor tiles. The floor elements of the subfloor are made of a material that ensures good shock absorption and is chosen in terms of thermal expansion coefficients so that it withstands the stresses in the outdoor area. It is also possible to use recycled material. The

Material and the structure of the cover layer is designed according to the requirements of each sport, such as tennis, basketball.

The disadvantage of such a construction is that the

Device-technical and also the laying technical effort to create the floor covering is considerable.

In WO 2006/042221 A3 and the US design US D618368 S a sports floor covering is shown, which consists of multi-layer grid-like

Plastic elements is formed, which also at their abutting edges Have locking elements. Such a grid-like floor is only applicable to sports with relatively low requirements. For one

For use in sports with high demands on the floor covering, such as outdoor basketball or outdoor tennis, such a floor is rather less suitable.

In WO 201 1/094461 a similar grid-like bottom is shown, which is designed with flexible inserts for stiffening. This soil shows in principle the same disadvantages as the soil previously described.

EP 2 239 024 A2 discloses a shock-absorbing floor covering which is constructed in two layers with a top layer and a base. The top layer consists essentially of a rubber granules, preferably from the

Recycling of used tires is produced. The pad is with a

Filament cavities carried out, which is designed for example as Filamentwirrlage. Such materials consist essentially of a polymeric material. The existing of the Filamenthohlraumkörpern pad may in turn be covered with two layers of fiber material to the upper layer and the lower ground. Such a floor covering can be laid and dismantled only with extremely great effort, so that it is more suitable for stationary applications, for example in playgrounds.

In GM 77 19 620 an outdoor flooring is described, which consists of a plurality of floor elements, which are designed with an elastically compliant layer, which is applied to a support body. The elastic layer again consists of a material resulting from the reprocessing of

Waste plastics, such as scrap tires is obtained. Also, this floor is designed for a stationary installation and can not meet the above-mentioned requirements in dynamic sports, such as tennis and basketball. In contrast, the invention has for its object to provide a removable outdoor flooring, which withstands even the most unfavorable weather conditions and meets the requirements for use in dynamic sports, such as tennis or basketball.

This object is achieved by an outdoor floor covering having the features of patent claim 1.

Advantageous developments of the invention are the subject of

Dependent claims.

According to the demountable outdoor flooring has a plurality of floor elements with an approximately rectangular base, wherein on abutting edges of a bottom element fitting elements are formed, which cooperate with corresponding fitting elements of an adjacent floor element in the sense of locking or centering. Each floor element has a multilayer structure, wherein a layer of an element, for example a load distribution element or a plurality of elements / load distribution elements is provided, on which a cover layer is applied. The flooring also has a damping layer on which the floor elements are applied. The load distribution layer, the

Cover layer and the damping layer are each water resistant, so that the floor even in adverse weather conditions, such as rain, is usable and meets the demands placed on him. According to the invention it is preferred if the cover layer is formed from a plate which covers the load distribution layer.

In this case, the plate and / or the load distribution layer of a base element made of plastic, plastic composites (for example WPC (Wood Plastic Composites), fiber or glass fiber reinforced plastics), mineral-filled plastics,

mineral sheet materials (including fiber-reinforced flex ceramics),

Honeycomb panel constructions, and / or made of wood and wood-based materials, by a treatment (eg sealing, impregnation, foliation) or due to their composition weatherproof, be executed. Also, thermal separation planes can be incorporated into these plate constructions.

In a particularly preferred solution, the damping layer is as

Foam layer executed, which is waterproof welded or laminated. The particular advantage of such a foam layer is that it can be delivered and designed, for example, as a roll or sheet material, so that the effort to create the lower layer is significantly lower than in the above-described prior art. As a foam layer can be a

Material that is not resistant to water per se. These

Water resistance is then ensured by the watertight weld or

Lamination formed.

Particularly suitable are a polyurethane composite foam or a crosslinked polyolefin foam have been found.

In principle, a plastic material which consists of the recycling of waste materials,

For example, used tires is made. Also suitable are air or dimpled films and rubber materials (e.g., rubber, sponge rubber, etc.).

In addition to the damping function, the damping layer can additionally assume a drainage function for the removal of water. Alternatively, the drainage can be solved by suitable subfloors or drainage mats.

On the preferably formed as a plate cover layer, a suitable surface coating can be applied, which is selected according to the requirements of each sport. In tennis, for example, an acrylic layer can be used, which is offset with the friction-improving materials, such as sand or corundum. When used as a basketball sports floor covering, the topcoat may be replaced by a suitable film comprising components of e.g. Polyethylene, polyolefin, polyvinyl chloride, ionomer, acrylic, polyester, polyurethane or

Polyurethane melt can be formed among others. The cover layer or the surface covering may be a decorative film or a decorative lacquer layer (for example made of acrylic, PUR or HotMelt). In one embodiment of the invention, the plate is made of PVC or a fiberglass material, while the load distribution elements are made of ABS.

According to the invention it is preferred if the cover layer or the

Surface covering is provided with Spielfeldmarkierungsabschnitten, so that the entire field mark is formed by laid in a given laying pattern floor elements without post-processing.

In order to avoid unintentional release of the floor elements or the emergence of over-tooth, the floor elements can be designed with a locking device, can be locked together via the adjacent floor elements.

Load distribution elements or fitting elements arranged at the abutting edges may be formed, at least in sections, from a more wear-resistant material than the other load distribution elements. In the top layer of a

Floor element may be used fitting elements which engage in corresponding recesses of an adjacent floor element.

Also, thermal separation planes can be incorporated into these plate constructions.

A preferred embodiment of the invention will be explained in more detail below with reference to schematic drawings. Show it:

Figure 1 is a perspective view of a removable outdoor sports flooring;

Figure 2 is a view of the sports flooring according to Figure 1 from below and FIG. 3 shows a detail of the bottom view from FIG. 2.

The outdoor sports flooring 1 described below is designed to be removable, and can be designed for example in games series, such as outdoor basketball tournaments on almost any flat surfaces. After the tournament, the floor is then dismantled and transported to the next venue. Particularly suitable is the below described sports flooring for outdoor basketball, in which both teams play on a single basket. This comparatively young sport is enjoying increasing popularity both in the US and in Europe and there are already quite lucrative tournaments taking place, organized by different organizers. Due to the removable outdoor sports flooring, it is possible to perform such tournaments at different locations with minimal requirements on the structural conditions. It is in principle only necessary that a suitable substrate is provided. Thus, such tournaments can be carried out practically on every level parking lot, which must be leveled with a bitumen layer if necessary.

The same applies to outdoor tennis tournaments, as is given by such removable sports flooring, the possibility far from the

Tennis stadiums, tournaments, training camp or the like.

The floor described below is designed to meet the various standards, for example in basketball, the standard DIN V 18032 Part 2, April 2001, EN14904 or the FIBA Standard 2010. The same applies to the applicable standards for tennis or other sports.

Figure 1 shows a schematic representation of an embodiment of a removable outdoor sports flooring. This is on a subfloor, not shown, for example, a cement screed or a

Laid bitumen layer. The floor covering 1 consists in principle of a

Damping layer 2, on which a plurality of bottom elements 4, 6, 14 are laid. These are designed and joined together so that they are at high Loads immovably on the damping layer 2 and thus also on the

Subsoil are, without an over-tooth or the like arises.

Each of the floor elements 4, 6 consists in principle of a plurality of load distribution layer forming elements, hereinafter referred to as load distribution elements 8, which are connected to a cover layer 10. As indicated in FIG. 1, a mark 12 can then be applied to this, which, when the floor is laid, complements a playing field marking, it being understood, of course, that the individual floor elements 4, 6 are laid according to a predetermined laying plan.

Depending on the sport, a suitable surface coating can be applied to the cover layer 10. As mentioned above, for example, in a tennis sports flooring a per se known acrylic layer can be rolled, in which the friction-improving particles, such as quartz sand or the like is embedded.

In basketball, film layers are usually applied to the topcoat. The cover layer 10 itself consists for example of a

plate-shaped, water-resistant material. In this case, the plate and / or the load distribution layer of a bottom element made of plastic, plastic composites (for example WPC (Wood Plastic Composites), fiber or glass fiber reinforced plastics), mineral-filled plastics, mineral plate materials (u.a.

fiber reinforced flex ceramics), honeycomb panel constructions, and / or of wood and wood-based materials obtained by a treatment (e.g.

Impregnation, foliation) or weather-resistant due to their composition. Also in these plates constructions thermal

Parting levels to improve the thermal insulation to be incorporated. These materials may be veneered to enhance visual appearance and then sealed waterproof.

The damping layer 2 may for example be formed from a polyurethane composite foam or from another elastic foam layer. Since such layers are not resistant to water per se, this is suitable waterproof welded or laminated, so that on the one hand the excellent

Steaming properties of the material is not watertight material can be exploited and on the other hand, a permanent water resistance is guaranteed. Such damping properties can not be achieved with the sub-layers of the prior art described above.

In principle, however, it is also possible to use a damping layer of a per se water-resistant material, for example, from recycled scrap tires, air or nub foams, rubber materials, PU-based plastics, crosslinked polyolefins or the like, although the attenuation often much worse than in the above-described waterproof welded or laminated foam layers. This can be solved by a suitable geometry of the damping layer, which can also be connected to the cover layer. In certain sports, however, reduced damping may be acceptable.

The structure of the load distribution layer 8 will be explained with reference to Figure 2, which shows a bottom view of the sports floor covering according to Figure 1, wherein, however, the damping layer 2 is omitted. It can be seen in this illustration, the approximately distributed as a rectangular plate load distribution elements 8, on which the plate-shaped cover layer 10 is applied. The side edges of the approximately

square load distribution elements 8 are at about 45 ° relative to the

Side edges of the cover layer 10 employed. The connection between the cover layer 10 and the plurality of load distribution elements 8 can be done for example by gluing or by clamping. In Figure 2 are three

Floor elements 4, 10 and 14 shown, wherein the two bottom elements 4, 10 along a butt joint 16 and the two bottom elements 4, 10 and the

Floor element 14 along a perpendicular thereto extending butt joint 18 abut each other. One recognizes in this representation that the in the butt joint area

arranged load distribution plates 8 of a bottom element in sections beyond the butt joint in a recess region 20 of the respective adjacent

Immerse floor element, this overlap is reciprocal. It is in the region of a butt joint, here the butt joint 16, on a bottom element 6 a Pass recess 22 is formed, in which a fitting projection 24 of the other bottom element 4 dips accurately, so that the two bottom elements 4, 6 are position-centered relative to each other. The reference numeral 24 is a

Designated locking device over which the adjacent panels 4, 8 can be clamped together in a simple manner. The basic structure of this lock and the floor elements is shown in EP 1 197 61 1 B1 of the Applicant, this document, however, relates to an indoor sports floor, which is not usable in the outdoor area. Figure 3 shows the basic structure of the locking device 26, it can be seen in this illustration, two adjacent load distribution elements 8a, 8b of two along the joint 16 adjacent floor elements 4, 6, said load distribution elements 8a, 8b with their corner regions in sections on the butt joint 16 addition to each cantilever other floor element. According to Figure 3, the load distribution element 8a is designed with a pocket-shaped recess 28 in which a coil spring 30 is mounted pivotably about a pivot axis 32. The other load distribution element 8 is likewise designed in a corresponding manner with a recess 34, from which a fixing bolt 36 protrudes, which protrudes in the

Locking state of one turn of the rod spring 30 is positively and positively embraced, wherein the spring in the locking engagement, d. h., In the state shown in Figure 3 extended somewhat in length, we thus an effective in the direction of investment force component is applied to the adjacent floor elements 4, 6. These are thus once positively fixed on the coil spring 30 and on the other form fit over the fitting projection 24 and the fitting recess 22. In the unlocked state, the snake spring 30 is in the pocket-shaped recess 28th

swung in and can be a special tool in a simple way when laying the bottom in the also pocket-shaped recess 34 of the adjacent

Floor element 4 are pivoted until they the fixing bolt 36 with

Preload encompasses. With regard to further explanations of the bottom construction, reference is made to the aforementioned EP 1 197 61 1 B1 for the sake of simplicity.

Preliminary tests showed that such a floor with a water-resistant top layer, water-resistant load distribution elements (load distribution layer) and a so that not inherently connected damping layer remains playable for a long time even in the most adverse weather conditions and maintains its predetermined damping values and the required surface quality for each sport. The laying is extremely simple, since the individual floor elements 4, 6 can be locked or unlocked in a simple manner via the locking device 26. Also, the laying of the damping layer is very simple, since it can be provided as a roll material or as a plate-shaped material, wherein the actually not water-resistant material of the damping layer by

laminated, welded or otherwise protected against water-resistant.

It is preferred if the damping layer is designed to be relatively large area, so that a damping layer element can be covered with a plurality of bottom elements 4, 6.

Another advantage of the outdoor sports flooring is the very small storage space requirement, so that, for example, a transport between the individual venues is possible with little effort.

Disclosed is a demountable outdoor sports flooring, which consists of a variety of floor elements, which in turn is a layer of

Have load distribution elements on which a cover layer is applied. These floor elements rest on a damping layer, wherein the

Load distribution elements, the cover layer and the damping layer are water resistant.
