    DETAILED DESCRIPTION

    [0067] With reference to figures, the moving system 1 for vehicles 50 is part of an amusement ride 100, for moving at least one vehicle 50 from a first fixed rail portion 101 of the amusement ride 100.

    [0068] In particular, the moving system 1 moves the at least one vehicle 50 at least between a first fixed rail portion 101 and a second fixed rail portion 102 of the amusement ride 100.

    [0069] With reference to FIG. 1, portions of the rail of an amusement ride 100 are visible which form part of the path, which may have various sections with different curvature or straight portions.

    [0070] The fixed rail portions 101, 102 can be part of a path with different straight and curved sections, for example a closed track loop.

    [0071] The moving system 1 according to the invention comprises a support structure 2 which is fixed to the ground or to a base platform, i.e. a support structure 2 that, in use, is generally placed on the ground or, more in general, coupled to (or leaned on) an external surface or platform.

    [0072] At least one pivoting arm 10, 10; 20, 20 is coupled to the support structure 2 to pivot around a respective pivot axis A1, A1; A2, A2 with respect to the support structure 2, and at least one movable rail portion 3 for supporting the vehicle 50 is constrained to the at least one pivoting arm 10, 10; 20, 20. With reference to FIGS. 2 and 3, it has to be noted that the at least one pivoting arm 10, 10; 20, 20 can be pivoted both clockwise and counterclockwise from a first position, preferably its resting position P1, preferably an equilibrium position, and the movable rail portion 3, constrained to the pivoting arms 10, 10; 20, 20, pivots, or swings, along a circular pathway, tracing at least an arc of the circle.

    [0073] Preferably, the at least one pivoting arm 10, 10; 20, 20 is pivoted to perform one or more oscillations, with an angle equal to or less than 180? starting from the first position P1, preferably the resting position P1 of the moving system 1. In other words, the at least one pivoting arm 10, 10; 20, 20 is pivoted to perform one or more oscillations, tracing an arc of circumference through an angle that depends on the location of said first and second positions. In the shown embodiment said angle is substantially equal to 180? starting from the resting position P1 of the moving system 1.

    [0074] According to a possible embodiment, during the first oscillation, the at least one pivoting arm 10, 10; 20, 20 with the vehicle 50 supported on the movable rail portion 3, is pivoted from the resting position P1 through an angle comprised between 0? and 180?, preferably substantially equal to 90?, then the pivoting direction is inverted, and the at least one pivoting arm 10, 10; 20 20 is pivoted back toward the resting position P1, and it traverses the resting position P1 and pivots through an angle comprised between 0? and 180?. According to this path, during a single oscillation, the at least one pivoting arm 10, 10; 20, 20 with the vehicle 50 supported on the movable rail portion 3 is in the resting position P1 twice: at the beginning of the oscillation, before the at least one pivoting arm 10, 10; 20, 20 is firstly pivoted from the resting position P1, and after the pivoting direction is inverted, the at least one pivoting arm 10, 10; 20, 20 drops back and traverses the resting position P1. As will be better discussed in the following, the angle of the one or more oscillations depends on the displacement between the first position P1 from which the movable rail portion 3 is moved and the second position P2 to be reached.

    [0075] As above mentioned, during pivoting of the arms 10, 10; 20, 20, the end of each arm 10, 10; 20, 20 moves along a path which is typically a circular path, wherein the ends of an arm 10, 20; 10, 20 are the two areas of the pivoting arms 10, 20; 10, 20 placed at the greatest distance from the relevant arm axis A1, A1; A2, A2.

    [0076] According to an aspect, the pivoting arms 10, 10; 20, 20 are pivoted at the same angular speed. In other words, at a given time, during operation of the moving system 1, all the arms 10, 10; 20, 20 have the same angular speed. The angular speed of the pivoting arms 10, 10; 20, 20 may be varied over time.

    [0077] According to a possible embodiment, the moving system 1 comprises at least one couple of pivoting arms 10, 10; 20, 20, constrained to opposite sides of said movable rail portion 3.

    [0078] According to a possible preferred embodiment shown by way of example in FIG. 1, the moving system 1 comprises two couples of pivoting arms 10, 10; 20, 20, wherein the pivoting arms 10, 10; 20, 20 of each couple are constrained to opposite sides of the movable rail portion 3.

    [0079] With reference to the shown embodiment, couples of opposite arms 10, 10; 20, 20 substantially share the same arm axis. As an example, in the shown (preferred) embodiment, there are four arms 10, 10; 20, 20, and two arm axes.

    [0080] With reference to FIG. 1, arms 10, 10 share the same pivot axis, and similarly arms 20, 20 share a second pivot axis.

    [0081] Even if a couple of arms 10, 10; 20, 20 share the same pivot axis, the pivot points are distinct one from the other, i.e. there is a single and distinct pivot point for each arm 10, 10; 20, 20. Due to this fact, there may be a minimum difference, due to tolerances, between the orientation of the pivot axes of opposite arms of a couple of arms. However, such a minimum difference, due to previously mentioned tolerances, fall within the definition of substantially sharing the same arm axis.

    [0082] With reference to the attached FIGS. 1-4, the support structure 2 comprises two supports 2, 2, and the pivoting arms 10, 10; 20, 20 of one couple of pivoting arms are constrained to a respective trestle support 2, 2, such that they result opposed to each other.

    [0083] Each arm 10, 20; 10, 20 is typically coupled to the support structure 2 by means of a hinge point or pivot point.

    [0084] Preferably, two pivoting arms 10, 20; 10, 20 constrained to the same support 2, 2 are disposed parallel to each other.

    [0085] It has to be noted that the pivoting arms 10, 10; 20, 20 of a couple are opposed to each other, such that they can be constrained to opposite sides of the movable rail portion 3 with respect to its longitudinal axis X.

    [0086] According to a possible embodiment, the opposite pivoting arms 10, 10; 20, 20 of each couple of pivoting arms 10, 10; 20, 20, are pivotable around the respective pivot axes A1, A1; A2, A2 in parallel planes.

    [0087] Furthermore, all the pivot axes A1, A1; A2, A2 lie on the same plane.

    [0088] The movable rail portion 3, carrying the vehicle 50, is constrained to the at least one arm 10, 20; 10, 20, with plurality of seats for the users of the amusement ride 100.

    [0089] The movable rail portion 3 is preferably constrained at the ends of the pivoting arms 10, 20; 10, 20, wherein the ends of an arm 10, 20; 10, 20 are the two areas of the pivoting arms 10, 20; 10, 20 placed at the greatest distance from the relevant arm axis A1, A1; A2, A2.

    [0090] According to a possible embodiment, the vehicle 50 is supported on the movable rail portion 3 constrained to the arms 10, 20; 10, 20 so that the seats do not change their orientation with respect to the movable rail portion.

    [0091] In other words, according to an embodiment the users are not turned upside down during the pivoting of the arms 10, 20; 10, 20.

    [0092] The at least one pivoting arm 10, 10; 20, 20 of the system 1 according to the invention is pivoted to perform one or more oscillations for moving the movable rail portion 3 supporting the at least one vehicle 50, from a first position P1 wherein the rail portion 3 is in connection with the first fixed rail portion 101 of the amusement ride 100.

    [0093] According to a possible embodiment, the at least one pivoting arm 10, 10; 20, 20 is pivoted by means of known means. As an example, not visible in the shown embodiment, one or more motor is used to cause a rotation of the at least one pivoting arm 10, 10; 20, 20 with respect to the support structure 2.

    [0094] More in particular, one or more motor can be used to control the pivoting of the at least one pivoting arm 10, 10; 20, 20 during both the raise from the resting position P1 and the subsequent drop toward the resting position P1.

    [0095] It has to be noted that the one or more motor used to cause a rotation of the at least one pivoting arm 10, 10; 20, 20 with respect to the support structure 2 can invert its rotation direction, such that the at least one pivoting arm 10, 10; 20, 20 can be alternatively pivoted clockwise and counter-clockwise. In this way the oscillation of the at least one pivoting arm 10, 10; 20, 20 is always controlled during both the raise from the resting position P1 and the drop toward the resting position P1.

    [0096] At the end of said one or more oscillations the movable rail portion 3 supporting the at least one vehicle 50 reaches at least one second position P2 wherein the rail portion 3 is in connection with a second fixed rail portion 102 of the amusement ride 100.

    [0097] As previously mentioned, the second position P2 may be higher or lower than the first position. In another embodiment, the second position may be at the same height and in an embodiment the second position may be corresponding to the first position. In the latter embodiment, the movable portion of rail is oscillated and eventually brought back to its initial position P1 from which the vehicle may proceed to ride back along the previously run rail portion. In an embodiment, not shown in the figures, the ride path continues after the first position P1 and the vehicle can thus continue along the fixed rail, following the same initial direction, e.g. from left to right in the figures.

    [0098] It has to be noted that the movable rail portion 3 is constrained to the at least one pivoting arm 10, 10; 20, 20 with its longitudinal axis X having the same orientation of the longitudinal axes of the first fixed rail portion 101 and of the second fixed rail portion 102.

    [0099] Preferably, the movable rail portion 3 is constrained to the at least one pivoting arm 10, 10; 20, 20 with its longitudinal axis X which is substantially perpendicular to the pivot axis A1, A1; A2, A2 of the at least one pivoting arm 10, 10; 20, 20.

    [0100] In this way, as will be better discussed in relation to the method according to the invention, the vehicle 50 arriving at the first fixed rail portion 101 is moved toward the movable rail portion 3 and stopped on the movable rail portion 3 maintaining the same travel direction. Similarly, at the end of the one or more oscillations, wherein the movable rail portion 3 is in connection with the second fixed rail portion 102, the vehicle 50 is moved toward the second fixed rail portion 102 maintaining the same travel direction.

    [0101] With reference to the attached figures, the first position P1 from which the movable rail portion 3 is moved, and the second position P2 reached by the movable rail portion 3 at the end of the one or more oscillations, are placed at different heights h1, h2 with respect to the ground.

    [0102] According to this embodiment, the value of the angle of the oscillations of the at least one pivoting arm 10, 10; 20, 20 depends on the height value h2 of the second position P2 with respect to the height value h1 of the first position P1.

    [0103] According to an aspect the second position P2 (see for example FIG. 7) is arranged at a height h2 greater than the height h1 of said first position P1 (see for example FIGS. 5 and 6). At the end of said one or more oscillations said movable rail portion 3 supporting the at least one vehicle reaches at least one second position P2 wherein said rail portion is in connection with the second fixed rail portion 102 that is arranged at greater height h2 with respect to said first position P1 wherein said rail portion is in connection with said first fixed rail portion 101. According to an aspect, the first position P1 is arranged close to the ground (see for example FIGS. 5 and 6 wherein the vehicle in the resting position P1 is arranged in the closest position to the ground), while the second position P2 is arranged at greater distance from the ground (see for example FIG. 7), preferably is arranged at the greatest distance from the ground that can be reached by means of the pivoting movement of the pivoting arm.

    [0104] According to a further possible embodiment, not shown in the attached figures, the first position P1 from which the movable rail portion 3 is moved, and the second position P2 reached by the movable rail portion 3 at the end of the one or more oscillations, are placed at the same height with respect to the ground. As above mentioned, according to this embodiment, the movable portion of rail is oscillated and eventually brought back to its initial position P1 from which the vehicle may proceed to ride back along the previously run rail portion.

    [0105] In an embodiment, not shown in the figures, the ride path continues after the first position P1 and the vehicle can thus continue along the fixed rail, following the same initial direction, e.g. from left to right in the figures.

    [0106] It has to be noted that, with reference to the attached figures, the moving system 1 is always disclosed in connection with an amusement ride 100 comprising two fixed rail portions 101, 102, but alternative configurations wherein a moving system 1 is used in connection with an amusement ride 100 comprising three or more fixed rail portions are not excluded, wherein the three or more fixed rail portions can be reached with the pivoting arms performing oscillations with different angles.

    [0107] With reference to FIG. 1, the movable rail portion 3 is rotatably constrained, or hinged, to the at least one arm 10, 10; 20, 20 at a respective at least one rotation axis A3, A3; A4, A4 of the movable rail portion 3 with respect to the at least one arm 10, 10; 20, 20.

    [0108] According to a possible embodiment, the at least one oscillation of the at least one arm, preferably four arms 10, 10; 20, 20 around the respective pivot axis A1, A1; A2, A2 with respect to the support structure 2, results in the rotation of the movable rail portion 3 around the rotation axis A3, A3; A4, A4 of the movable rail portion 3 with respect to the at least one arm 10, 10; 20 20.

    [0109] In other words, preferably, the rotation of the movable rail portion 3 around the rotation axis A3, A3; A4, A4 is only caused by the pivoting of the at least one arm 10, 10; 20, 20, with no external contribution such as, for example, use of a motor.

    [0110] In particular, the at least one oscillation of the at least one arm 10, 10; 20, 20 with respect to the support structure 2, results in that the movable rail portion 3 rotates around the at least one rotation axis A3, A3; A4, A4 in order to maintain its longitudinal axis parallel with respect to the ground.

    [0111] As above mentioned, the present description is further directed to an amusement ride 100, for example a roller coaster, comprising at least one first fixed rail portion 101 and at least one second fixed rail portion 102 and a moving system 1 according to the invention, wherein the moving system 1 moves at least one vehicle 50 at least between said first fixed rail portion 101 and said second fixed rail portion 102.

    [0112] It has to be noted that, with reference to the attached figures, the amusement ride 100 is shown comprising two fixed rail portions 101, 102, but alternative configurations wherein the amusement ride 100 comprises three or more fixed rail portions are not excluded, wherein the three or more fixed rail portions can be reached with the pivoting arms performing oscillations through different angles.

    [0113] With reference to FIG. 1, portions of the rail of an amusement ride 100 are visible which form part of the rail path, which may have various sections with different curvature or straight portions.

    [0114] The fixed rail portions 101, 102 can be part of a similar complex rail path with different straight and curved sections, for example a closed track loop.

    [0115] FIG. 1 shows a possible embodiment of the amusement ride 100, wherein the first fixed rail portion 101 comprises a removable end portion 101 which can be moved away, and preferably lowered or moved laterally, with respect to the fixed rail portion 101 after the vehicle 50 is moved to the movable rail portion 3.

    [0116] The movement of removable end portion 101 after the vehicle has been loaded on the movable rail portion 3 is also visible in FIG. 6, wherein after the vehicle has been loaded on the movable track portion 3 (see FIG. 5), the movable rail portion 3 is moved away, and preferably lowered or moved laterally (see FIG. 6).

    [0117] In this way, the first fixed rail portion 101 does not interfere with the movable rail portion 3 during the one or more oscillations.

    [0118] According to a possible embodiment, not shown in figures, the second fixed rail portion 102 comprises a removable end portion which can be moved away, and preferably raised or moved laterally, with respect to the fixed rail portion 102 after the vehicle 50 is positioned on the movable rail portion 3.

    [0119] In this way, the second fixed rail portion 102 does not interfere with the movable rail portion 3 during the one or more oscillations.

    [0120] In the following, a possible embodiment of the relevant steps of a method for operating a moving system 1 according to the invention will be briefly disclosed.

    [0121] The method according to the invention comprises a first step (a) of moving at least one vehicle 50 from a first fixed rail portion 101 of the amusement ride 100 to the movable rail portion 3 of the moving system 1.

    [0122] With reference for example to FIGS. 5 and 6, this step is preferably operated while keeping the movable rail portion 3, constrained to the pivoting arms 10, 10; 20, 20, fixed in the first position P1, wherein the rail portion 3 is in connection with the first fixed rail portion 101 of the amusement ride 100.

    [0123] The method according to the invention comprises the further step (b) of pivoting the at least one pivoting arm 10, 10; 20, 20 to perform one or more oscillations for moving the movable rail portion 3 supporting the at least one vehicle 50 from the first position P1 wherein the rail portion 3 is in connection with said first fixed rail portion 101.

    [0124] With reference for example to FIG. 7, at the end of said one or more oscillations in step (b), the movable rail portion 3 supporting the vehicle 50 reaches a second position P2 wherein the movable rail portion 3 is in connection with a second fixed rail portion 102 of the amusement ride 100.

    [0125] In other words, according to a possible embodiment with reference to the attached figures, in order to move the vehicle 50 from the first position P1 to the second position P2, the moving system 1 is operated to swing clockwise from a first position P1, shown for example in FIG. 5 or 6, to an intermediate position as shown for example in FIGS. 3 and 4.

    [0126] The system then returns, swinging counterclockwise, towards the first position P1, passing the resting position and reaching for example the position in FIGS. 1 and 2, and then swings clockwise towards the second position P2 shown in FIG. 7.

    [0127] It should be noted that this path is described only as an example and is to be considered non-exclusive. It should also be noted that the first position P1 can be crossed several times during the oscillating movement of the moving system 1.
