Springboard made of fiberglass plastic, in particular for Halles = and »relbade *.

The innovation concerns a springboard made of fiberglass for use in halls or Outdoor pools.

Plastic diving boards are known per se. However, in terms of their vibration behavior and their static and other properties, they are not sufficient because of the versatile ones Requirements placed on such a system Above all, they are very heavy in their construction and therefore complex and uneconomical.

The innovation eliminates these disadvantages.

It combines the water, weather and corrosion resistance inherent in fiberglass with a shape which, with extremely low weight, has very high values for the moment of inertia and resistance compared to conventional designs

The springboard is designed as a half-timbered hollow girder

forms, in which the upper chord with the lower chord is connected by webs arranged at right angles or at an oblique angle to the belts.

The following are exemplary embodiments of the subject matter of the drawings Innovation described. Show it

Figure 1 a cross section through the springboard with oblique angled Webs;

Figure 2 a cross section through the

Springboard with bars arranged at right angles to the straps.

Both versions basically have the same static characteristic, namely the Distance and connection between an upper chord 2 and a lower chord 3 by webs, which cavities with the straps together

So you could call the whole thing a half-timbered hollow girder.

In Figure 1, the hollow truss 1 is designed so that the webs 4- in its entirety as a profiled coherent intermediate plate 1 with Trapezoidal profile arranged between the upper and lower belt and through polymerization connected to these.

Figure 2 shows another type of construction of the trussed hollow girder. Here webs arranged at right angles to the belts connect them to one another, one Bounding series of rectangular cavities.

The cavities between the webs 4 can be covered with a material, e.g. with Polyurethane foam 5 can be filled. This allows the vibration behavior be modified.

Often the wish is expressed, the vibration characteristics of the springboard variable design - a requirement with regard to the frequently changing Use of the jumping device, e.g. as a school or artificial jump or high-performance springboard, is made frequently enough. In order to achieve this, you can go into the cavities A coherent filler 6 (Fig. 2) can be inserted between the webs. This dampens the vibrating board designed to be changeable without the need for support points for the springboard

Claims (2)

I Il I I I I I II have to be moved. In this way, the "elasticity" of the board can be adapted to the respective requirements. Protection claims 1. Springboard made of fiberglass, e.g. for outdoor and indoor swimming pools, characterized in that the springboard is designed as a half-timbered hollow beam (1) with the top chord (2) with the lower chord (3) through webs (4) arranged at right angles or at an oblique angle connected is. 2. springboard according to claim 1, characterized in that the webs (4) in their Entire as a profiled intermediate plate (1) are introduced between the upper and lower chord. Ji springboard »see that. Claims 1 and characterized in that the cavities between the webs with a material, ζ · Β · Polyurethane foam (5) are filled. 4-. Springboard according to claims Λ to 3, characterized in that bodies (6) are inserted into the cavities for any change in the vibration characteristics of the springboard, which in addition to increasing the rigidity of the adjustable damping of the vibration characteristics of the springboard.
