DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Module 1 serves construction of recreation track, especially the bicycle one, which has a framework on which the modules are being arranged.

As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, module 1 has upper part 2 intended for riding on it, constituting non-ruled surface and in the top view has tetragonal shape with one rounded side. Module 1 has the first side wall 3 and the second side wall 4 and left front wall 5 and opposite to it right front wall 6, located between the first side wall 3 and the second side wall 4. The terms “right” and “left” have conventional meaning, because module 1 is symmetrical to its transverse axis.

The first side wall 3 and the second side wall 4 create base of module 1. The first side wall 3 and the second side wall 4 form with upper part 2 an obtuse angles, therefore stability of module on the ground, on which it is to be seated, is increased. Whereas the left front wall 5 and the right front wall 6 form an acute angle a in the top view.

The left front wall 5 and the right front wall 6 serve joining the module 1 with other modules during construction of recreation track. The location of the module 1 shown in FIG. 5 and FIG. 6 within example recreation track results in changing riding direction on the track by an angle, which is equal to angle a, formed between the left front wall 5 and the right front wall 6, which is shown in FIG. 5. The acute angle a, formed by the left front wall 5 and the right front wall 6 in the module shown in FIG. 5 equals to 15°, but the acute angle in other embodiments of the track may adopt value from the 10°-20° range.

The upper part 2 of module 1, intended for riding on it, constitutes non-ruled surface, which in the view from the left side wall 5 is concave towards base, formed by the first side wall 3 and the second side wall 4, as shown in FIG. 4. This influences safety of a person using the track in such manner, that it reduces possibility of falling out of the track, because the concavity of upper part 2 and its inclination in transverse plane both to the first side wall 3 and the second side wall 4 results somehow in “pulling off” the person riding on the track towards the centre axis of module 1 driving direction.

The first side wall 3 and the second side wall 4 have in side-view, shape of figure having three straight sides and one side constituting an arch, bent oppositely to base, upper point of which is located between the left front wall 5 and opposite to it right front wall 6.

As shown in FIG. 4, the first side wall 3 is higher than the second side wall 4.

The edges of upper part 2, adjoining the first side wall 3 and the second side wall 4, feature rounding 7. which is shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4. The radius of rounding 7 ranges from 50 mm up to 100 mm,

The upper part 2 of module 1. intended for riding on it. has rough surface. which increases running safety, and the roughness is obtained by painting the module 1 with paint, laying a layer of quartz silica over it prior to the paint is dried out, removing excess silica after the paint is dried out and laying subsequent layer of the paint.

The module 1 for construction of recreation track, especially the bicycle one, is made of glass fibre reinforced plastic.
