  • Patent number: 8845439
    Abstract: An amusement device includes at least one swinging arm, one end of which is suspended so as to be rotatable about a swinging axis and one free end of which is displaceable along at least a part of a circular path about the swinging axis. A carrier is suspended from the free end of the swinging arm and is rotatable about an axis of rotation transversely to the swinging axis. Furthermore, there is at least one support device for at least one person which is suspended from the carrier at a distance from the axis of rotation thereof. The support device is rotatable with respect to the carrier.

  • Patent number: 8672769
    Abstract: A supporting system for a mast, for example for a swing carousel, includes stabilizing vehicles which each include a chassis, sets of wheels for moving the stabilizing vehicle, coupling elements near one end of the chassis, and at least one stabilizing arm which is displaceable between an inoperative position in which the stabilizing arm is swung in and a swung-out position in which the stabilizing arm extends outwards with respect to the chassis. At their free ends, the stabilizing arms each have a support for stabilizing the stabilizing vehicle on the ground in the swung-out position of the stabilizing arm. A base is provided for the mast, which base includes complementary coupling elements situated opposite one another, one complementary coupling element of which is coupled to the coupling element of a stabilizing vehicle and the other complementary coupling element of which is coupled to the coupling element of another stabilizing vehicle.
