Abstract

This invention relates to an elastic floor for sports which consists of the sine-form supports (4) (with the same bending rigidity) and another sine-form supports (4') (with the same bending rigidity) which are perpendicular to the supports (4). This elastic construction supports the bearing board (9) with the parquet on top.

Description

The invention relates to a resilient floor, which has the property of absorbing and mitigating the impact of athletes on bounces, and the repulsion of the ball is almost the same as that of a solid concrete base.

The construction of sports floors is known, where the floorboards are laid on the boards and these are foamed elastic substrates to achieve the elasticity of the floor. Other structures are constructed in different versions of prismatic moldings, supported on support posts with lined wooden or rubber tiles, placed only parallel or crosswise. For prismatic beams, deformations occur exclusively in the hazardous area, ie. in the middle and between the supporting points where the tension in the material is greatest.

The present invention relates to the construction of an elastic sports floor with supports of the same bending stiffness, in which the material, in our case wood, has a uniform tension throughout the length.

Holders of the same bending stiffness have a lower self-weight and therefore better mitigate impact shocks.

The ideal shape of beams of equal bending stiffness of constant width is defined by the equation of the quadratic parabola y = h ^, where the right part of the beams is equal to the left part.

Since in practice the parabolic shape of the beam is difficult to carry out, the parabolic surfaces are replaced by tangential planes, with the height of the beam above the two support points not equal to zero, but with

The wedge-shaped design of wooden beams is technologically and economically pointless because the cut-off parts are waste, nor is it possible to continuously cut the prisms.

The problem is solved with a sinusoidal shape, which brings us closer to the parabolic shape, which also enables the indus- trial production of supports of the same bending stiffness by the winding cutting of prismatic moldings.

It is an object of the invention to achieve the following physical values in the elastic sports floor of the pre-defined species (DIN 18032);

• Impact absorption coefficient

KA ', _W > 53% • ball repulsion, where the coefficient between the height of the reflection on the elastic sports floor and the height of the reflection of the ball on a rigid basis

BR> 90% • Plane floor load at static load, where floor load at a distance of 500 mm from the force point of operation is less than 15% of the force displacement f SDODZ / J - 15% fo • Standard deformation of at least 2.3 mm.

According to the invention, this task is solved by the features given in the characteristic part of the first patent claim. The specification of the solution according to the invention is given in the sub-claims.

The invention is further specified on the basis of the embodiments presented in the accompanying drawings, in which it shows:
