DESCRIPTION OF EMBODIMENTS

[0046] FIG. 1 shows in perspective view an amusement device 1 according to the invention in a first position. The amusement device has a carrier 30 for passengers. The carrier 30 can make a full swing around a swinging axis Sa. The swinging axis Sa extends horizontal. The carrier 30 maintains a defined position while swinging around the swinging axis. In other words, the carrier 30 maintains a predetermined angular position, here a horizontal position as shown, while swinging around the swinging axis Sa. This defined position of the carrier 30 has for its purpose to maintain the passenger a natural upright position. Seating 47 is only shown schematically. Any seating will suffice. It is even possible for passengers to stand.

[0047] The amusement device 1 comprises a first tower 10 as best shown in FIG. 2 and a second tower 20. In FIG. 1 only a top section 80, 90 of the first and second towers 10, 20 is shown. The towers 10, 20 support the swing structure 70. The first and second tower 10, 20 may connect directly to ground. It may also be conceivable that the swing structure 70 is supported by a wall element (not shown). As an option, the first and second towers 10, 20 can be placed on a transportable unit 2 shown in FIG. 2, like a trailer or a container. The first and second tower 10, 20 are spaced apart. The swing structure 70 is arranged between the first and second tower 10, 20. The first and second tower 10, 20 do not extend in swinging space so that the carrier 30 can make a full 360 swing around the swinging axis Sa. In other words the first and second swinging arms 11, 21 are adapted to rotate over 360 degrees around the swinging axis Sa.

[0048] In order to maintain the carrier 30 in the defined position while swinging around the swinging axis Sa, the amusement device 1 comprises a stability mechanism 40. The stability mechanism 40 connects to the carrier 30 and to the first tower 10, and here, also the second tower 20. The stability mechanism 40 works in parallel with the support function of the towers 10, 20. Or, to put it differently, the carrier 30 is connected to the first and second tower 10, 20 through both the stability mechanism 40 and the first and second arm 11, 21. The stability mechanism 40 and the first and second arm 11, 21 work in parallel. The stationary first and second tower 10, 20 function as a reference for the carrier 30. The stability mechanism 40 is configured to maintain the carrier 30 in an upright orientation, that is the defined position, while the carrier 30 rotates around the swinging axis Sa. In other words, the stability mechanism 40 imposes a defined angular position to the carrier 30 while rotating around the swing axis Sa. The stability mechanism 40 comprises first and second parallel guide link systems 43, 45. The first and second parallel guide link systems 43, 45 complement each other in stabilizing the carrier 30.

[0049] The amusement device 1 comprises a first swinging arm 11 and a second swinging arm 21. The first and second swinging arm 11, 21 extend between respective first ends 12, 22 and second ends 13, 23. The first and second swinging arms 11, 21 are configured to together rotate around the horizontal swinging axis. The swinging axis Sa is defined by the first ends 12, 22 of the swinging arms 11, 21. The amusement device 1 comprises at both sides of the swing structure 70 an assembly of a respective tower 10, 20, a respective swing arm 11, 21 and a respective parallel guide link systems 43, 45. Only one of said assemblies is described.

[0050] The first swinging arm 11 is at its first end 12 rotatable connected to the first tower 10. The carrier 30 is rotatable connected to the second end 13 of the first swinging arm 11. The carrier 30 is rotatable with respect to the first swinging arm 11 around the carrier rotation axis Cra. The carrier rotation axis Cra is adapted to stay parallel to the swinging axis Sa while the swinging arms 11, 21 rotate around the swinging axis Sa. Here, the carrier 30 has in use a centre of mass above the carrier rotation axis Cra. The carrier 30 is connected to the first tower 10 through the first parallel guide link systems 43 of the stability mechanism 40. Thus, the carrier 30 connects to the first tower 10 through the first swing arm 11 and the first parallel guide link system 43. The first swing arm 11 and the first parallel guide link system 43 work in parallel to connect the carrier 30 to the first tower 10. The carrier is rotatable with respect to the first swinging arm 11. However, the carrier 30 is fixedly connected with the first parallel guide link system 43 with respect to rotation around carrier rotation axis Cra.

[0051] The carrier 30 connects to the first tower 10 through the first swing arm 11 in order to transmit forces from the carrier 30 to the first tower 10. The carrier 30 connects to the first tower 10 through the first parallel guide link system 43 in order to impose the defined position to the carrier 30. The defined position is an angular position, wherein the carrier 30 is substantially horizontal as perceived by passengers.

[0052] Regarding the first parallel guide link system 43. As background, a parallel guide link system has two parallel link members that are at one end rotationally coupled to a reference. The other end of the two parallel link members is rotationally coupled to a so called crankshaft. The parallel guide link imposes a position to the crankshaft and that position is based or derived from the reference. Now turning to the amusement device 1. The first and second parallel guide link system 43 comprises two parallel link members 11, 41, thus the swing arm 11 forms one of the parallel link members. Further reference is made to the swing arm 11, and the parallel arm member 41. The swing arm 11, and the parallel arm member 41 have equal length, as is required for parallel guide link systems. It will be clear that length refers to spacing of centres of rotation. If required, one or both of the swing arm 11 and parallel arm member 41 are length adjustable to enable to accommodate manufacturing tolerances. The swing arm 11, and the parallel arm member 41 are freely rotatable coupled to the first tower 10. The first tower 10 is the reference for the first parallel guide system 43. The parallel arm member 41 is freely rotatable around a link member rotation axis Lma. The link member rotation axis Lma is eccentric with respect to the horizontal swinging axis Sa. Here, the parallel arm member 41 is connected to the first tower 10 through a rotation mechanism 44, here a slewing bearing 44. The slewing bearing 44 extends around the swinging axis Sa. The first parallel guide link systems 43 comprises a crankshaft 46. The crankshaft is fixedly connected to the carrier 30 to impose a position to the carrier 30.

[0053] As explained, each of the respective first and second tower 10, 20 has a respective first or second parallel guide link systems 43, 45 associated therewith. In other words, the first parallel guide link systems 43 connects to the first tower 10 and the and second parallel guide link systems 45 connects to the second tower 20. The positions of the first and second parallel guide link systems 43, 45 differ when projected in a plane perpendicular to the swinging axis Sa. In this shown configuration, the positions of the first and second parallel guide link systems 43, 45 differ in that respective crankshafts 46, 47 make an angle of about 90.

[0054] The amusement device further comprising a counterweight 50. The counterweight compensates the weight of the carrier 30 and passengers. A counterweight 50 is attached to the first swinging arm 11 and the second swinging arm 21.

[0055] The amusement device further comprising a horizontal member 60. The horizontal member 60 is oriented along the swinging axis Sa. The horizontal member 60 connects the first ends 12, 22 of the first and second swinging arms 11, 21.

[0056] FIG. 2 shows a side view of the amusement device 1 of FIG. 1 in a second position. In this second position, the first swinging arm 11 extends horizontal. As shown, the carrier 30 maintains the defined angular position, which is a horizontal position. The amusement device 1 comprises a first tower having a top section 80. The first and second tower 10, 20 are placed on a transportable unit 2 like a trailer or a container.

[0057] FIG. 3 shows a side view of the amusement device 1 of FIG. 1 in a third position. In this third position, the first swinging arm 11 extends vertical. As shown, the carrier 30 maintains the defined angular position, which is a horizontal position. The first and second parallel guide link systems 43, 45 are arranged in differing positions as can be best seen referring to the parallel link members 41, 42. The first and second parallel guide link systems 43, 45 are arranged in differing positions such that that respective crankshafts 46, 47 make an angle of about 90 which is best seen in FIG. 8A.

[0058] FIG. 4 shows a perspective view of a detail of the amusement device of FIG. 1. The top section 80 of the first tower 10 is shown. The swing arm 11 and the parallel arm member 41 are partly shown. A mounting plate 61 is fixedly mounted with the top section 80. The mounting plate 61 and the top section 80 can be an assembly of parts or be of one part. The mounting plate is described with reference to FIG. 6. A powered drive 65 is shown that is coupled to the first swinging arm 11 to swing the carrier 30 around the swinging axis Sa. The rotation mechanism 44 is a 360 type of rotation mechanism. The rotation mechanism 44 may comprise a plain bearing, a sliding contact bearing, a ring bearing, a ball bearing or any other suitable means. Here, the rotation mechanism is a slewing bearing. The rotation mechanism 44, has a centre of rotation Lma1 in FIG. 6B that is offset with respect to the swinging axis Sa. Here, the centre of rotation Lma1 is offset with respect to the swinging axis Sa by a spacing s which is better shown in FIG. 6B. The axis of rotation of the rotation mechanism 44 is parallel with respect to the swinging axis Sa.

[0059] FIG. 5 shows a different perspective view of the detail of FIG. 4.

[0060] FIG. 6A shows a perspective view of another detail of the amusement device of FIG. 1. The mounting plate 61 has a mounting seat 63 for connecting the slewing bearing 44 to the mounting plate 61. The mounting seat 63 extends at the outer circumference of the mounting plate 61. The mounting plate 61 has a further mounting seat 64 for rotatably connecting the first swing arm 11 to the mounting plate 61. As shown, the further mounting seat 64 is eccentric with respect to the mounting seat 63. Therefore, the swinging axis Sa and the link member axis Lma are offset over a spacing s. The mounting seat 63 extends around the further mounting seat 64. Both the first and second parallel guide link systems 43, 45 have a respective mounting plate 61. The respective mounting plates 61 have different orientations as can be seen in FIG. 3. Because of the different orientations of the respective mounting plates 61, the first and second parallel guide link systems 43, 45 are arranged in differing positions.

[0061] The spacing S is determined by the mounting plate 61. Thus the rotation mechanism 44 and the bearing (not shown) of the swinging axis Sa have the mounting plate 61 in common. This improves an accurate spacing S.

[0062] FIG. 7 shows a perspective view of another detail of the amusement device of FIG. 1; The carrier 30, the swing arm 11 and the parallel arm member 41 are partly shown. The other ends of the swing arm 11 and the parallel arm member 41 are rotationally coupled to the crankshaft 46. The crankshaft 46 has a defined predetermined length, more precise the distance d between the two centres of rotation 48, 49 is predetermined. The distance d between the two centres 48, 49 of rotation is in accordance with the spacing s between the swinging axis Sa and the link member axis Lma as shown in FIG. 6. The distance d and the spacing s are equal. The crankshaft 46 is fixedly connected to the carrier 30 to impose an angular position to the carrier 30.

[0063] FIG. 8a-e shows the stability mechanism 40 of the amusement device 1 of FIG. 1 in different subsequent positions.

[0064] The stability mechanism 40 is configured to maintain the carrier 30 (not shown here) in an upright orientation, that is the defined position, while the carrier 30 rotates around the swinging axis Sa. In other words, the stability mechanism 40 imposes a defined angular position to the carrier 30 while rotating around the swing axis Sa. The stability mechanism 40 comprises first and second parallel guide link systems 43, 45. The first and second parallel guide link systems 43, 45 complement each other in stabilizing the carrier 30. The first and second parallel guide link systems 43, 45 are arranged in differing positions as can be best seen referring to the respective crankshafts 46, 47 in FIG. 8A-8E. The first and second parallel guide link systems 43, 45 are arranged in differing positions such that that respective crankshafts 46, 47 make an angle of about 90. The angle of about 90 is constant during a full rotation of the first and second parallel guide link systems 43, 45 around the swinging axis Sa. FIG. 8A to 8E show 5 discrete subsequent positions of a half rotation of the first and second parallel guide link systems 43, 45 around the swinging axis Sa.

[0065] The first and second parallel guide link systems 43, 45 are arranged in differing positions as is also clear from the arrangement of the swinging axis Sa and respective link member axis Lma1, Lma2 of the first and second parallel guide link systems 43, 45. As can be seen, the centre of rotation, or also link member axis Lma1, Lma2 is offset with respect to the swinging axis Sa by a spacing S which is better shown in FIG. 6. The axis of rotation of the rotation mechanism 44 is parallel with respect to the swinging axis Sa.

[0066] The present invention has been described above with reference to a number of exemplary embodiments as shown in the drawings. Modifications and alternative implementations of some parts or elements are possible, and are included in the scope of protection as defined in the appended claims.
