发明名称 EVENT COMPLEX
摘要 An event complex provided with an event surface (2) and a number of stands (3) surrounding the event surface, one or more of which stands are slidable relative to the event surface over slide elements (38, 45) which are arranged between the stand(s) and a ground and which comprise a low friction material. These slide elements can herein be arranged on a part of the ground located outside the event surface. By displacing the stand(s) the event complex can be made suitable for both large-scale and small-scale events. Each slide element can form an endless belt which is guided over reversing rollers (49) and a transporting part of which is located between the stand(s) (35) and the ground (36) and a return part of which is guided through the stand(s) or the ground. Between the displaceable stand(s) and the ground can further be arranged drive means (46) which are formed by piston/cylinder combinations (67) mounted on the stand(s) or the ground and a plurality of push-off points (48) with the free outer end of the pistons and arranged with interspaces in the displacement direction.
