EP1811086A1 - Method for the production of a flexible, weather-proof, frost-resisting, all the year round usable surface for ways, playgrounds and sports areas. In particular for tennis courts in interiors and exteriors - Google Patents

Abstract

The method involves attaching a pressure distribution layer on an elastic layer (2), where the pressure distribution layer is adhered with a plastic cord by a rock material. A gliding layer (4) is interspersed on the pressure distribution layer, and a colored rock material layer is applied on a gliding layer. A marking groove is cut into the pressure distribution layer and the gliding layer and a marking line is pressed in the pressure distribution layer and the gliding layer.

Description

The present invention relates to paths, play and sports surfaces. Especially tennis courts. Furthermore, the invention relates to a method for producing a surface-elastic, frost-proof, water-permeable and year-round usable covering made of colored, crushed and ground natural stone materials for paths, play and sports surfaces. Especially for tennis courts.

With or without the production of a loosely fixed elastic, granular rubber granulate vibrating layer onto which an open-pore, frost-proof, water-permeable, year-round usable pressure distribution layer is bonded, bonded from plastic binders. This consists of colored, crushed and ground rock materials of different grain sizes and a dust-free and shear-resistant cover slip layer applied from colored rock material.

Furthermore, the invention relates to a method for producing a binding and dust-free cover and sliding layer, which consists of artificial and / or ground colored rock and / or plastic materials.

Furthermore, the invention relates to a method for producing an ecologically and physiologically harmless odorless, colorless, aqueous agent for permanent dust binding.

Finally, the invention relates to a method for the permanent solid insertion of elastic markings. Without the use of auxiliaries, auxiliaries and fixing materials.

Area elastic floors for sports and playgrounds (especially tennis courts) are known to be used in various constructions, which consist mainly of wood and / or pressed foam parts. Outside these constructions can not be used, since the entire construction is destroyed by the action of moisture.

Furthermore, these constructions can be installed only on bonded base courses such as asphalt, concrete or screed, which were secured in advance by complex procedures against rising damp.

Furthermore, these constructions are made of wood and / or pressed foams, on which then pressure distribution plates are screwed or glued. Then the actual pitch cover is then designed and / or firmly glued.

These constructions have a favorable for the athletes large-scale pressure distribution, which protect the ligaments and joints. The disadvantage is the susceptibility to moisture, price and durability. In addition, they can only be used indoors.

Furthermore, there are numerous indoor and outdoor constructions designed to replicate the playing characteristics of a clay court, clay court, brickyard, which are preferred by most tennis players. But all have one only a slight point elastic effect.

In addition, these structures are not playable all year round, not frost-resistant and can not be installed on unbound base courses. In addition, these types of flooring have a low water permeability.

In addition, these types of construction are maintenance-intensive, not playable all year round and require a complex and regular irrigation.

The classic tennis court, which consists of broken brick flour, is still considered by most tennis players to be ideal because of its slip-resistance. However, it has the disadvantage that it requires a very intensive care, has no elasticity and practically every year has to be prepared again.

This is extremely costly, especially in today's mass of places, so that was looking for new solutions to develop a surface, on the one hand has the properties of the Ziegelmehltennisplatzes, on the other hand, however, requires little care and has a particularly advantageous playing conditions of a surface elastic floor structure. Furthermore, it can be installed indoors and outdoors.

For example, a sports field is known in which applied to a bound support layer, an elastic plastic layer and solidified by means of an adhesive. After peeling off this elastic layer, a color layer (red or green) is subsequently applied in order to optically improve the black rubber particles of the elastic layer, which are usually dyed with carbon black.

A tennis court made in this way is easy to maintain, but has the disadvantages that it is not slip-friendly. This means that it becomes smooth after some time and also has an irregular and too elastic ball bounce behavior. The latter behavior is partly due to unevenness in the elastic surface, but partly also due to the elastic particles acting directly on the ball

To improve the sliding behavior of such a tennis court, was with DE-A-28 26 206 proposed to provide the non-sliding surface of the rubber lining with elastomeric grains, wherein between the grains loosely smaller elastomeric grains are provided to fill the gaps. Although such a space is also easy to maintain, but in turn has the disadvantage that the loosely scattered particles act on the fixed particles abrasive. This has the consequence that such a coating is smooth after some time and must be deducted again.

Another covering is from the DE-A 32 31 2231 known. In addition to the ease of maintenance already mentioned above, such a place has a relatively good and long-lasting playability, although it should be noted that such a place is not suitable for tennis tournaments, as it has an unfavorable Ballabsprungverhalten in relation to the conventional clay brick. This ball-dropping behavior is mainly due to the fact that the unevenness in the rubbery body layer can not be sufficiently compensated by the brick-breakage layer. That is, the thickness of the layer of clay is relatively uneven. In this respect, there is a more or less strong direct contact of the tennis ball with the rubber bodies that produce a different jumping behavior of the tennis ball due to their elastic properties, as the conventional brick breaker meal layer.

The DE-AS 22 56 566 relates to a floor covering for tennis courts, the lower layer of which consists of an elastic polymeric material (expanded polystyrene) on which an upper open-pored plate layer of a hard mineral (granular fired clay) is solidified by a weather-resistant binder and bonded to the lower layer. On this clay layer soft burnt clay flour is scattered, the interface area between the hard and the soft clay flour on the binder, which is present in the hard clay flour to be connected to the soft clay flour. However, the tennis court surface described herein does not meet the desired, gentle to the musculoskeletal system of the player requirements, since the hard mineral layer is too thick and therefore too inelastic.

The invention is therefore based on the object to provide a method for a surface-elastic and largely maintenance-free, water-permeable, frost-proof, all-season recordable and usable on any surface indoors and outdoors covering. With a for the athlete (especially tennis players) advantageous, shear-resistant, dust-free and lubricious covering and sliding layer and with a permanently and firmly inserted height-appropriate elastic playing field marking. A covering that more than meets the sports functional and sports medical requirements and is also to be used for all sports that require a flat surface.

According to the invention, a tennis court is provided which has the positive characteristics of the conventional sand-brickmills tennis court, but is area elastic and can be applied to any existing surface (bound or unbound) indoors or outdoors. In addition, frost-resistant, water-permeable and playable all year round.

Consisting of a colored rock material in a broken, ground, granular form, which is bound with a plastic binder and is pressure-resistant, impact-resistant, tough-elastic and open-pored. Applied to a loosely fixed and bound with a plastic binder granular elastic layer.

Furthermore, this tennis court requires no elaborate spring overhaul and only minor care. On the course no treads or bumps can occur. The bounce is consistent in all weathers and in all places.

The top-level overlay consists of a colored rock material in crushed and ground form and has the same texture and high shear strength as the pressure distribution layer, which does not dust even in dry conditions and where the marking lines are permanently and evenly laid.
