Description

The present invention relates to a riding or sports ground, in particular suitable for example for dressage or show jumping riding floor, and a method for producing such a riding or sports ground.

A conventional riding or sports ground has a laid on a substrate arrangement of plate-shaped, juxtaposed floor fasteners and a footing on the floor mounting elements. The floor fasteners serve to create a stable foundation for the footing or a stable floor surface. Depending on the application, the riding surface (eg show jumping, dressage, vaulting, western riding, lunging, etc.) or the sports ground (eg depending on different sports) must generally meet different special requirements (in particular with regard to elasticity, shock absorption, sure-footedness, water balance, etc.). ), which can be influenced in part by the correct choice of floor fasteners.

Suitable floor fasteners for the construction of riding surfaces are for example in the EP 0 667 927 B1 and the DE 200 19 812 U1 described or known as so-called perforated mats, riding mats and tournament mats Otto Sport International GmbH, Altdorf, Germany. In some cases, the floor fasteners should also provide good water management, ie store water on the one hand to prevent the footing from drying out, and on the other hand remove excess water to prevent over-hardening or silting of the footing. These perforated mats are usually laid on a water-permeable intermediate layer of gravel or split. In a further development of this construction discloses the EP 2 599 916 B1 a riding or sports ground, which has a laid on a substrate layer of substantially plate-shaped, juxtaposed floor fasteners, wherein between the substrate and the location of floor fasteners a layer of elasticity of textile or Plastic chips is heaped up as a separate component from the ground fasteners.

It is the object of the present invention to provide an improved riding or sports ground, which can provide better protection of the health of the horses or athletes.

This object is achieved by the teaching of the independent claims. Advantageous embodiments of the invention are specified in the dependent claims.

Fig. 2

a sectional view of a riding floor according to a second embodiment of the invention.

Fig. 1 shows the construction of a first embodiment of a riding floor according to the invention.

On a basically arbitrary substrate 10, the surface of which is preferably flat or planed, first a layer of unbound rubber granules 14 having a layer thickness of, for example, about 5 cm is poured up in order to form an elasticity and shock absorption layer 12. The rubber granulate 14 is preferably made of a recycled material, for example truck tires. The rubber granule 14 has, for example, a (mixed) grain size in the range of 1.0 to 4.0 mm. Instead of the granules 14 also a flour or a granule-flour mixture can be used; Instead of the rubber material, a plastic material may also be used. The elasticity and shock absorption layer 12 also forms a drainage layer.

On the rubber granules 14 of the elasticity and shock absorption layer 12, a water-permeable nonwoven fabric 30 is then placed, for example in the form of a road construction fleece quality GRK 2, 3, 4 or 5 with a thickness of, for example, about 1.0 mm. The road construction web is, for example, unrolled in a plurality of webs side by side on the elasticity and shock absorption layer 12.

A layer 16 of plate-shaped, juxtaposed bottom attachment elements 18 is provided on the nonwoven fabric 30. These floor fastening elements 18 are, for example, so-called perforated mats from Otto Sport International GmbH, Altdorf, Germany, as they are exemplified in US Pat DE 200 19 812 U1 are disclosed. The floor fasteners 18 are made of a rubber or plastic material and have a thickness of, for example, 3 to 5 cm (based on the base plate, ie without the projections described below).

As in Fig. 1 illustrated, the bottom attachment elements 18 in this embodiment, on its upper side facing away from the base 10 (top in Fig. 1 ) each have a plurality of projections 26a, 26b in two different heights (relative to the base plate of the floor fasteners 18). The higher projections 26a and the lower projections 26b are in each case distributed in a matrix-like manner on the upper side of the floor fastening elements 18, the two matrix-like distributions being offset from one another, so that a higher projection 26a always follows a lower projection 26b and vice versa. This embodiment of the floor fastening elements 18 offers a high slip resistance for the horses. For example, the higher protrusions 26a have a height of about 30 mm, and the lower protrusions 26b have a height of about 20 mm.

As in further Fig. 1 illustrated, the bottom attachment elements 18 also on its underside 10 facing bottom (bottom in Fig. 1 Each of these protrusions 28 has the same height (relative to the base plate of the floor fasteners 18) and is shorter than the lower protrusions 26b formed on the upper surface of the floor fasteners 18. With the aid of these projections 28 on the underside, the floor fasteners 18 can be better anchored to the underlying elasticity and shock absorbing layer 12.

In addition, the floor fasteners 18 are designed to be permeable to water. For this purpose, for example, the floor fastening elements 18 each have a plurality of apertures 24 that extend through the floor fastening elements 18 in the layer thickness direction. The nonwoven fabric 30 under the floor attachment elements 18 prevents the rubber granules 14 of the elasticity and shock absorption layer 12 from penetrating into these openings 24 and clogging them.

On the layer 16 of the floor fastening elements 18, a footing layer 20 of fine-grained sand or a sand-fleece mixture is provided. The layer thickness of this footing layer 20 is for example about 4 to 10 cm. In riding floors, this footing 20 usually forms the uppermost layer of the riding floor, but optionally this footing 20 can also wear a (artificial) lawn or the like.

In the embodiment of Fig. 1 In addition, an optional retention layer 22 is provided between the floor attachment elements 18 and the tread layer 20. The retention layer 22 is formed, for example, of gravel, split, gravel and / or coarse sand and is intended to prevent the finer material of the footing 20 penetrates into the openings 24 of the floor fasteners 18 and clogged them. The layer thickness of this retention layer 22 is for example about 30 mm; it is preferably dimensioned such that the higher projections 26a of the floor fastening elements 18 no longer protrude from the retaining layer 22.

Overall, the riding floor thus constructed offers the horses on the one hand a high degree of slip resistance (esp. By the bottom fasteners provided with the projections 26a, 26b) and on the other hand a high elasticity and shock absorption (esp. By the elasticity and shock absorption layer 12 under the layer 16 of floor fastening elements 18). In addition, the riding surface is water-permeable, so that optimal irrigation (i.e., neither too dry nor too wet) can be achieved.

Fig. 2 shows the structure of a second embodiment of a riding floor according to the invention. The same or corresponding components are identified by the same reference numerals as in the first embodiment.

In contrast to the first embodiment of Fig. 1 Here, the floor fasteners 18 have a substantially planar underside 32 (bottom in FIG Fig. 2 ) and the nonwoven fabric 30 is omitted between the elasticity and shock absorption layer 12 and the layer 16 of bottom attachment elements 18.

In contrast to the embodiment of Fig. 1 is in this second embodiment, the rubber granulate 14 is not poured loose on the substrate 10, but filled in flexible pockets 34 made of a water-permeable and tear-resistant material, for example in jute sacks. These pockets 34 are laid side by side and possibly also one above the other on the substrate 10. This embodiment variant of the elasticity and shock absorption layer 12 offers, in particular, during storage, transport and laying of the rubber granulate 14. Since the pockets 34 are permeable to water, the function of the elasticity and shock absorption layer 12 remains as a drainage layer.

As in Fig. 2 illustrated, the rubber granules 14 may be filled in a plurality of tubular pockets 34 with a single interior. Alternatively, the rubber granulate 14 can also be filled in pockets 34 with a plurality of separate internal spaces. These can be formed, for example, starting from pockets 34 with a single interior through corresponding seams.

Otherwise, the embodiment corresponds to Fig. 2 the above-described first embodiment of Fig. 1 ,

The different features of the first and the second embodiment can also be combined with each other arbitrarily.
