Structure of accessory element for equipment of floorball training court and use of it for formation of floorball simulator

Subsidiary element for floorball training rink arrangement that is made as latticework formed by:

• two parallel end plates;
• several threaded rods as stiffening members;
• two elastic string structures disposed in two parallel planes between the two end plates and orthogonal to the two end plates, wherein each of the string structures present one side of mentioned latticework, where the strings are arranged parallel to each other without touching each other, wherein the threaded rods are arranged between the two parallel end plates and attached thereto, and the threaded rods are disposed between the two string structures so that during use a ball can touch one of the two string structures without touching the threaded rods, and wherein each end plate is provided with:
• holes, in which threaded rods are inserted and fastened thereto by means of washers assuring rigidity and load bearing capacity of the subsidiary element;
• holes, in which strings are criss-cross stringed in two parallel planes and each string of the string structure is attached to the end plates independently one from another so that the string structure is pretensioned.
