is coated, wherein between the upper boundary surface of the Bal ¬ kens and the mentioned cover layer several layers of substances of different elasticity are glued.

Description de r b ekannten technical solutions:

The modern gymnasium (non-skidding) used in the Turnspori modern gymnastic gymnastics gymnastics gymnastics gymnastics gymnastics gymnastics gymnastics gymnastics gymnastics gymnastics

Gymnastic apparatus primarily for learning and practicing the jumps, and gymnastic apparatus mainly used for competitions «

The object of the provided on the beam body above elastic upholstery, after the DS-PS No. 1 5? 8632 turn bar running consists u _e a "therein, the shocks experienced by the Beina of Turners to dampen e

But the padded gymnastic bars have the disadvantage that the learning and practicing the connecting steps "is considerably difficult due to the strong changes in shape of the elastic padding and therefore such gymnastic equipment for learning and demonstrating exercises with high difficulty and consequently are not suitable for Wettkärapfe,.

The requirements placed on the gymnastic bars used are contained in the International Federation of Sporting Competition Rules 1974, pp. 28-30, to meet the requirements set out, for example, on the gymnastics apparatus between the upper interface of the bar and the wrapping layer 6 mm thick, unspecified layer of a sponge-like matter and the width of the bar corresponding 5 Dim thick wooden plate, the so-called end timber installed.

The disadvantageous characteristics of the competition gymnastics circuit is that it overstrains the gymnast's legs during both learning and practicing, which leads to fatigue, especially during training, so that the acquisition of the exercises on such devices is very time-consuming is

Aim of the Invention;

It is an object of the invention to remedy the above deficiencies largely au, <.

Dario gun ^ _- ( _{1 of the} above).

It is an object of the present invention to provide such a solution which is equally suitable for learning, practicing and fatigued sports and, at the same time, having the corresponding internatio

- 3 standards.

According to the invention, this object is achieved in that, on a base layer of 20-4-5 Sh ⁰ , advantageously of 36 Sh ⁰ hardness, and 65-25 % i advantageously of 72.5 % Eindrückbarkeit an intermediate layer of 75-95 Sh ° hardness, 40-65 % Sindrückbarkeit and 10-25 % permanent Eindrückbarkeit and on this one suitably made of the material of the base layer top layer is adhered, wherein the ratio of the interlayer wall thickness to the wall thicknesses of the base layer unior cover layer in the range of 1 ~ 1O mm between the · Fourth of 10-1.25, advantageously between 3 »75-2.5.

In an advantageous embodiment of the solution according to the invention, the cover layer is formed on der.gesamten cross-sectional contour of the beam body »

Embodiment:

The invention will be explained below with reference to the accompanying drawings na-forth, which represents an advantageous embodiment of the gymnastics beam in section.

The cross section of the beam construction is designed in terms of its shape and dimensions according to the provisions of the International Gymnastics Federation. On the upper surface of the corresponding with

et

Strengthened beam body 1 is first adhered to the base layer 2 , the one made of a material of 20-45 Sh °, advantageously of 35, Sh ° hardness and 65-95 % _t advantageously made of 72.5 % Eindrückbarkeit. 1-4 mm, preferably 2-3 mm thick layer.

On the base layer 2 a dimensionally stable intermediate layer 3 is glued, the material 75-95 Sh ⁰ hardness, 40-65 % Eindrückbarkeit and "

-Λ- 212867

10-25 % permanent bond reversibility, and a thickness of 5-10 mm, advantageously of 7 ₍ 5 min possesses »

On the intermediate layer 3t ^au ^ the free edge bands of the base layer 2 and on the free surfaces of the contour of the beam body 1, a cover layer 4 is glued, whose material or thickness is advantageously equal to the base layer. Within the scope of protection of the invention, the Baikenkonstruktion can be formed exclusively with the laid on the intermediate layer 3 cover layer h . , '. ,

Finally, the entire beam is coated with a sheath layer 5 made of a step-proof (non-slipping) moisture-absorbing and wear-resistant material.

The advantage of the solution according to the invention lies in the fulfillment of the stated object, namely in the design of a gymnastic apparatus which equally fulfills the contrary requirements. Sports clubs and the Hungarian Gymnastics Federation have already issued appraisals about the gymnastics bars issued for testing. ·
