The subject of the utility model is a module for construction of recreation track, especially bicycle one.

Recreation tracks, intended particularly for riding a bicycle, but also inline skates, are known under pumptrack name and constitute specially prepared, small track, enabling riding a one-track vehicle (usually bicycle) and provide for comprehensive training. It is constructed from quick turns and moguls. It develops reflex, balance sense and condition of its users.

The modular track for riding inline skates is known from the French application document FR2757075. The track is made of horizontal surface, connected with modular, curved sections. The upper part of ending section is covered with a bumper having cylindrical shape. The slope is connected with platform by means of safety barrier. The curved surfaces are supported by frame, created of vertical, horizontal and oblique rods. They are stiffened with triangular rods and connected with each other by means of assembly plates. The horizontal surface is supported by the rods placed underneath, and inclination can be changed by means of variable height feet.

Solution of track, especially intended for skateboard and made of individual modules, is known from the European application document In order to arrange a track for skateboarding, which can be constructed in open air and which is long-life, while simultaneously has perfect rolling properties, it is proposed to construct the skateboard track from individual modules, which comprise of precast concrete units, so that feature perfect rolling properties on their running side, while simultaneously produce lower noise level than the tracks known to date. The solution of inline skates track, made of individual elements, is known from the European application EP0870523A1. The structure of the track is composed of multiple sections, which create hollow track with flat bottom and a number of ending sections, with which the structure obtains closed, semi-circular end. The hollow track is composed of concave sections, which have flat, horizontal platforms along elevation. The platforms serve starting or landing. Users may also move along the structure and along its semi-circular end. The concave sections are supported by struts. The structure can be supplemented with canopy.

The solution of inline skates track, made of individual elements, is known from the European application EP0796641A1. The inline skates track, containing at least one part with bent surface, whereas this part is composed of bent surface, which is supported mainly by curved strips, extending mainly in curvature direction of the bent plate.

The known tracks can be made of wood, concrete or also plastic, whereas, for example concrete can by poured out on-site of the track construction, or can be also made in form of modular components, produced outside the site and adequately selected, as required, which depends on terrain configuration or necessity of ensuring adequate construction of the track.

The recreation tracks known in the art, particularly the tracks made of concrete components, are distinguished with large weight, which entails high difficulties during their construction and also influences their cost. It is also important, that considering their geometry, known tracks do not provide optimum safety level of users.

The utility model aims at providing modular components for construction of recreation track, especially the bicycle one, which besides low costs of the track construction shall provide optimum trajectory of user run, which improves safety level and ergonomics of the ride and also provides possibility of constructing tracks featuring various shapes.

According to the utility model, the module for construction of recreation track, especially bicycle one, having framework, on which modules are being arranged, while the module has upper part intended for riding on it. The upper part is constituted by non-ruled surface, that in top view has tetragonal shape with two rounded sides. The module also has the first side wall and the second side wall, whereas the first side wall and the second side wall create base of the module. The module also has left front wall and opposite to it, right front wall. Both the walls are located between the first side wall and the second side wall. The left front wall and the right front wall are parallel to each other in the top view, and the first side wall and the second side wall form in the side view obtuse angles with the upper part.

Preferably, the upper part intended for riding on it, constitutes non-ruled surface, which in the view from the left side wall is concave towards base, formed by the first side wall and the second side wall.

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

Furthermore preferably the edges of upper part, adjoining the first side wall and the second side wall are rounded with radius from 50 mm up to 100 mm.

Also preferably the upper part of the module, intended for riding on it, has rough surface.

The subject matter of utility model is illustrated in drawing, in which figure 1 illustrates the module for construction of recreation track, especially bicycle one, in perspective view from the comer of the first side wall and the second side wall, figure 2 illustrates the module for construction of recreation track, especially bicycle one, in the top view, figure 3 illustrates the module for construction of recreation track, especially bicycle one, in perspective view from corner of the first side wall and the right front wall, figure 4 illustrates the module for construction of recreation track, especially bicycle one, in the perspective view from side of the right front wall, and figure 5 illustrates location of module for construction of recreation track, especially bicycle one in example recreation track.

As shown in fig. 5, module 1 for construction of recreation track, especially bicycle one, having framework on which other modular elements are being arranged, can be laid in the track close to oval in the place, where the track runs straight in principle as regards direction and determines passage over an elevation, as regards altitude to base.

As shown in fig. 1, fig 2, fig. 3 and fig. 4, module 1 for construction of recreation track, especially bicycle one, has on its upper side an upper part 2 intended for riding bicycle or other recreation vehicle on it. The upper part 2 is connected with the first side wall 3 and the second side wall 4 and with left front wall 5 and right front wall 6. The terms “right” and “left” have conventional meaning, because module 1 is symmetrical to its longitudinal axis.

The first side wall 3 and the second side wall 4 create base of module 1, on which the module 1 can be placed. The left front wall 5 and right front wall 6 are located between the first side wall 3 and the second side wall 4.

The upper part 2 of module 1 constitutes non-ruled surface, defining trajectory of user passage on the track over module 1. As shown in fig. 2, module 1 in the top view, that is from the upper part 2, has tetragonal shape with two rounded, opposite sides. The rounded sides on both sides of module 1 represent lower parts of the first side wall 3 and the second side wall 4. As shown in fig. 2. the left front wall right front wall 6 run vertically in principle. 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 first side wall 3 and the second side wall 4, in the side view form obtuse angles with the upper part 2 on both sides of the upper part 2, which is shown particularly in fig. 4, but also in fig. 1 and fig. 3. Such inclination of the first side wall 3 and the side wall 4 significantly influences stability of the run of the person using the recreation track, and hence his/her safety.

The upper part 2 of module 1 for construction of recreation track, intended for riding on it by person using the track, constitutes non-ruled surface, which in the view from the left front wall 5 or right front wall 6 is concave towards base, formed by the first side wall 3 and the second side wall 4, as shown in fig. 1 and 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 results somehow in “pulling off’ the person riding on the track towards the centre axis of module 1 driving direction.

As shown in fig. 1 and fig. 3, 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. Adequately selected arch bending curvature also influences safety of person using the track.

As can be seen from the above, non-ruled shape of the upper part 2 of module 1 is quite complex, because it defines both passaging over elevation, so that it has to be bent oppositely to base formed by the first side wall 3 and the second side wall 4 in the longitudinal axis of module 1, and concave in the view from the left front wall 5 or the right front wall 6. The edges of upper part 2, adjoining the first side wall 3 and the second side wall 4. have rounding 7 with radius ranging from 50 mm up to 100 mm. The surface of the module 1 upper part 2 is rough in order to ensure better adhesion for persons riding on the track. 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.
