Abstract: A roundabout for performing acrobatic figures such as barrel roll comprises a main arm rotatable around a central axis A and having a longitudinal axis C, a second arm rotatable about an axis of rotation B perpendicular to the longitudinal axis C of the main arm, and a vehicle fixed on the second arm at a distance from the axis of rotation B of the second arm and having a longitudinal axis z directed radially towards the axis of rotation B. The vehicle is fixed to the second arm so that its position with respect to the second arm does not change during the operation of the roundabout.

Abstract: An amusement device includes at least one platform movable with respect to a fixed chassis, in which the at least one platform includes at least one compartment to accommodate one or more passengers. The at least one compartment has no seating and includes an arrangement for manually supporting the one or more passengers who are disposed standing freely inside the at least one compartment.

Abstract: A seat for amusement apparatus, unusually suitable for allowing the user to adopt a new position on the apparatus, comprising a support and means for immobilising the user on the support. The immobilising means comprise at least one support in front of the user and opposing means suitable for acting on the user's back. The opposing means comprises an arm which can move between a lowered position in which the user can sit down on the support and a raised position in which one end of the arm abuts against the user's back.

Abstract: Amusement apparatus which permits unusual compactness and easy transportation comprises a vehicle for accommodating users, the vehicle being suitable for following a path in space which comprises a component due to oscillation about a center of instantaneous rotation and a component due to rotation about an axis oriented variously in space. The vehicle is supported on a support structure comprising two rails the shape of which defines the shape of the component due to oscillation of the vehicle.

Abstract: Amusement apparatus (10) which permits unusual compactness and easy transportation comprises a vehicle (12) for accommodating users, the vehicle being suitable for following a path in space which comprises a component due to oscillation about a centre of instantaneous rotation and a component due to rotation about an axis oriented variously in space. The vehicle (12) is supported on a support structure (16) comprising two rails (22) the shape of which defines the shape of the component due to oscillation of the vehicle (12).
