Four in Hungary, and more than one hundred canoeing pool or aquatic sports stadiums work in Europe, Asia and in the overseas countries, which are related to aquatic sports or are in connection with aquatic sports like rowing, canoeing, motor boating and water skiing etc.. These stadiums are provided with long and straight canoeing pool stretching hundreds of meters so that different races can be organised at the same place. The audians is placed in a grandstand being relatively short to the length of the pool and built at the last 1-2 hundred meters of the pool and being near the finish-section thereof, since the finish the most exiting part of the races can be seen the best from here. As a result of this fact, the races can be visited by a small number of people and the profit does not cover even the costs of the maintenance of the stadium. Furthermore, for the audians, there is a lot of dead time during the races passed between the start and the finish lines.

Consequently, although the stadiums frequented by a very few of audians cost a lot to build, neither the construction nor the maintenance clears their costs, because the stadiums can not be utilised much more.

Our scope with the present invention to create a stadium for aquatic sports, which is suitable not only for organising traditional aquatic sport races, but for such show sports such as'Indian Games'attracting the audians and enhancing the exploitage of the stadiums.

SUMMARY OF THE INVENTION To accomplish our scope above, is provided a stadium for aquatic sports according to present invention having a canoeing pool, and a grandstand arranged at least along the finish-section of the pool, and the stadium is provided by at least one bridge crossing the pool and provided by bridge-heads in opposite ends thereof, a strand lying close to a frontside of the pool, and a swimming area appointed on the surface of the pool, and lists connected to the strand, and further provided with a lane and an obstacle- course arranged at least along a shoreline of a finish-section of the pool.

Preferably, the shorelines are connected to each other by the at least one bridge arranged across the pool and situated adjacent the end of the grandstand, and said lane and said obstacle-course are formed between a respective one of the opposite bridge-heads of the at least one bridge and the lists.

Advantageously, the stadium for aquatic sports is provided with more than a bridge arranged across the pool, and said lane and said obstacle- course are formed as starting from the opposite bridge-heads of the bridge being furthest from the frontside of the pool and connecting also the bridge- heads being on the same shoreline.

The bridges arranged across the pool are connected to the bridge- heads in a disconnectable manner, preferably, and the obstacle-course is furnished with temporary and/or statically located obstacles.

The width of the lists preferably equal to the width of the swimming area, and the width of the strand arranged along the frontside of the pool is preferably equal to the width of the pool.

Advantageously, at least a shoreline of the pool is arranged along a shore suitably choosen of a natural-water, and one of the shorelines of the pool is formed in an artificially manner.

Preferably both the lane and the obstacle-course are arranged along the same shoreline, and at least one bridge-head of the at least one bridge is arranged on the water surface of the pool between the shorelines, and the ends of the lane and the obstacle-course being close to the end of the grand- stand and formed on the shoreline, and the bridge-heads are connected with members serving as a passable surface.

In one embodiment, the strand and the lists are arranged along the shoreline of the pool.

These and other features and advantages of the present invention will be more clearly understood from the following discussion with reference to the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1. shows a preferred embodiment of the aquatic sports stadium according to the present invention, arranged in a traditional canoeing pool, Figure 2. represents the first embodiment of the aquatic sports stadium according to the present invention, Figure 3. shows an embodiment of the aquatic sports stadium according to the present invention, provided with three bridges, in the Figure 4 there can be seen an embodiment of the aquatic sports stadium according to the present invention, arranged at one end of a dead channel, in the Figure 5. there can be seen an embodiment of the aquatic sports stadium according to the present invention, arranged at the side of a dead-water or a sea, Figure 6. is an embodiment of the aquatic sports stadium according to the present invention, arranged along a shoreline jutted out perpendicularly, and Figure 7. is a perspective scenery of an embodiment of the aquatic sports stadium according to the present invention.

The traditional sport stadium shown in the Figure 1. and its pool 2 arranged therein are suitable to form a stadium 1 according to the present invention. Note, that the stadium 1 according to the present invention could be created either at the respective shore-sections of natural waters, stagnant waters, or seasides too.

Turning to the 2 Figure, there can be seen a preferred embodiment of the aquatic stadium 1 according to the present invention. The pool 2 of the aquatic stadium 1 is provided by at least one bridge 3, preferably by more than a bridge 3 (for example three bridges 3) connecting the shorelines 7,9.

The bridges 3 arranged near the adjacent end 11 of the grandstand 6 of the stadium 1 allowing to form a lane 8 and/or an obstacle course 10 arranged along the shoreline (s) 7,9 connected to each other by means of bridges 3, providing the possibility to organise races being cyclically repeated in the visual field of the audians, at the finish-section 14 of the long pool 2 being inadequate to this purpose anyway. The bridges 3 are connected to the abutments 12 preferably in a disengaging manner to avoid impediting the racers (i. e. kayak, canoe, scullers etc.) in the case of organising traditional races.

Looking at the Figure 3, there is a detailed presentation of a preferred first embodiment of the aquatic sports stadium 1 according to the present invention. The pool 2 shown in the Figure 3. may be a traditional, very long and artificially established canoeing pool 2 filled with water. A both-end- evadable (in the water) swimming area 15 being shorter than the length of the finish-section 14 is buoyed out by means of direction-buoys along the longitudinal axis of the pool 2. A multilevel grandstand 6 is built adjacent at least a first shoreline 7,9 of the pool 2 and along the finish-section 14 of about 300 m of the pool 2 to receive many thousands of people. Between the grandstand 6 and the nearest shoreline 7,9 of the pool an obstacle course 10 may be arranged along the full length of the grandstand 6. On the obstacle course 10 there might be arranged even abiding or portable obstacles 13. Such obstacles 13 may be i. e. simple and traditional portable obstacles 13 used by hurdle-race or obstacles 13 formed by billets, like the hurdles of show-jumping, and poles, walls to climb, rope-ladders, rope- bridges, cradles, creep-holes, boulders etc., but in generally there may be arranged any type of obstacles 13 being to possibly be overcome by the competitors at least in full career. The obstacles 13 may be arranged parallel to the pool 2, or in complex combinations, such as the competitors starting from the first end of the obstacle-course 10 will arrive to the other end thereof.

Between the lists 5 formed adjacent the strand 16 arranged along the frontside 4 of the pool 2 and the bridges 3 is formed a lane 8 extending parallel to the shoreline 7 of the pool 2. The building-up of the lane 8 may be arbitrary, i. e. sanded, dirty, soily etc., or it can be covered by artificial coating, like a plastic material, and its tracing may be formed by curves or along a parallel line relatively to the shoreline 9 of the pool 2. In the embodiment of the present invention shown in the Figure 3. are arranged three bridges 3 connecting the obstacle course 10 and the lane 8, at the end 11 of the finish- section 14. In this case the obstacle course 10 and the lane 8 run up to the farthest bridge 3, also joining with the other bridges 3. The width of the strand 16 arranged along the frontside 4 of the pool 2 is preferably equal to the width of the pool 2. In the virtually prolongated direction of the pool 2 the length of the lists 5 arranged along the frontside 16 is at least enough to arrange archery tournaments, and its width preferably equal to the width of the swimming area 15. The strand 16 and lists 5 may be covered by a material arbitrarily choosen, preferably fine sand.

In the Figures 4., 5. and 6. are shown the preferred embodiments of stadium 1 according to the present invention, arranged by side of a water in the nature. The Figure 4., for example, represents a stadium 1 arranged in dead-channel of a river.

This arrangement differs from the solution according to the first embodiment of the stadium 1, by using only natural objects to prepare the obstacle-course 10.

In the Figure 5. is shown a stadium 1 according to the invention arranged on a linear shore of a bigger lake or sea. In this embodiment both the lists 5 and the strand 16 are formed along the natural shoreline 9, but a possibility is given to form the lane 8 and the list 5 and the strand 16 along the virtual distal shoreline 9 and along the artificially formed frontside 4 of the pool, respectively.

In the last case, the arrangement could be similar to the first embodiment of the stadium 1.

In the case of the embodiment showing in the Figure 6., the a seaside section placed perpendicularly to the adjacent section ensures even the artificially forming of supporting elements supporting the lane 8 (not shown) or-as you can see-the arrangement of the obstacle course 10 in the same shoreline 7,9 as the lane 8. The stadium 1 can be formed in a narrow beach of a lake or sea.

The stadium 1 according to the invention is suitable to organise also showsports, like"Indian games". The"Indian games"is a complex sport, like pentathlon, but against the latter it takes place in the same site: in the stadium 1 according to the invention. In order to be distinguishable, the competitors of groups racing against each other wear different kinds of signs having different colours-coloured dresses and/or caps-and they test their force in canoeing, swimming, archery, hurdle-racing and running, overcoming sequentially the different sections of the stadium 1, for example in the following order: canoe, in the section being between the bridges 3 and the lists 5 arriving to the strand 16, archery, arranged in the lists 5, hurdle-racing in the obstacle-course 10, running through a bridge being closer or further depending on the result achieved in the archery, followed by running in the lane 8.

The stadium 1 for aquatic sports is able to prevent the audians from being constrained to change the sites of races (disparately from the pentathlon), and involves a possibility for the owners of the stadiums 1 to increase the exploitage of existing pools 2, and furthermore, to enhance creating new and complex sports.
