Description

This invention relates to an amusement ride, and more particularly to an aerial amusement ride involving one or more riders being conveyed through the air.
There are a variety of amusement rides involving a rider or riders being conveyed through the air in a manner somewhat simulating flight. The rides can be on a relatively small scale for use in playgrounds, or on a much larger scale for use in fair grounds and theme parks.
One example of a ride involving conveyance of a rider through the air is a swing. Swings can range from the simple variety as commonly used in children's playgrounds to somewhat sophisticated structures requiring mechanisms for raising riders into a launch position from which they are released to swing through a curved trajectory. Whilst swings can provide an entertaining ride, they are generally rather limited in simulating flight, as typically riders only swing back and forth along a curved trajectory. Consequently, the rider achieves essentially the same ride each time.
Another ride involving conveyance of a rider through the air is an aerial carousel, where one or more riders are moved through a generally circular path. Typically, an aerial carousel involves a central column supporting a rotatable hub from which riders are suspended to be conveyed through a circular path about the column, thereby simulating flight. In a simple playground version of such an amusement ride, chains extend from the rotatable hub and have handles (typically configured as rings) attached to their free end so that they can be grasped by the riders. With such rides, the riders initially propel the hub by running around the column while gripping the chains, and thereafter lift their feet from the ground so as to move through the air, simulating flight. In more sophisticated arrangements, the aerial carousels may incorporate rider carriers (such as harnesses or carriages), and also a drive system for driving the hub to cause the rider carriers to move through a circular path around the central column. As with other aerial amusement rides, the ride offered by an aerial carousel is somewhat limited, as the riders merely move through a generally circular path, achieving essentially the same ride each time.
Another example of an aerial amusement ride is disclosed in US-A-4 576 373 .
It would be advantageous for there to be an aerial amusement ride which can move a rider through the air but with provision for the ride to be varied should that be desired in order to enhance the sensation experienced by the rider.
According to the present invention, there is provided an aerial amusement ride of the type in which riders are conveyed in rider carriers through the air, above the ground, in rotation around a column of a tower by a support structure that supports the rider carriers at a radial distance from the column on links that allow the rider carriers to move radially outwards from the column as the speed of the ride increases, characterised in that the column is of an open framework construction in which elongate elements are interconnected and braced by lateral elements with open spaces between said elongate and lateral elements.

Preferably, said support structure is arranged to be displaced along said tower and the ride further comprises second drive means for displacing said support structure along said tower.
With such an arrangement, the rider carrier can undergo motion involving rotation around the tower and also displacement along the tower to provide a change in elevation during the ride. The change in elevation as the rider moves in a path around the tower can enhance the sensation experienced during the ride.
Said hub structure may be rotatably supported on a ring structure adapted for displacement along said tower while being fixed against rotation with respect to said tower.
Preferably, said ring structure is mounted on said column for guided rolling movement therealong.

Figure 11 is a fragmentary view illustrating a rider carrier and suspension link for an amusement ride according to a further embodiment.

Referring to Figures 1 to 5 of the drawings, there is shown an aerial amusement ride 10. The aerial amusement ride 10 involves conveyance of riders through the air In a manner somewhat simulating flight at an elevation sufficiently high to provide a thrilling sensation.
The aerial amusement ride 10 comprises a tower 11 anchored to the ground 13. A support head 15 is mounted on the tower 13 and riders 17 are suspended from the support head 15 by way of flexible suspension links 19 for conveyance through the air about the tower.
The riders 17 are conveyed along a path which extends around the tower 11, with the elevation of the riders being selectively variable, as will be explained later.
The tower 11 comprises a base 21 and a column 23 mounted on the base 21. The column 23 is of framework construction, comprising a plurality of longitudinal elements 25 connected one to another by lateral elements 26 which provide bracing, as best seen in Figure 4 of the drawings. Each longitudinal element 25 is of rectangular cross-section and is oriented diagonally so that two adjacent faces 27, 28 thereof are outwardly facing, as best seen in Figure 4.
While not shown In the drawings, the column 23 in this embodiment comprises a plurality of column sections disposed in series one upon another, with adjacent sections being detachably connected together. With this arrangement, the height of the column, which is a matter of design choice, can be established by using an appropriate number of column sections. Additionally, the arrangement facilitates erection of the column 23, as it is merely necessary to fit one column section upon another, typically with the assistance of a crane or other suitable load lifting apparatus.
Because of the framework construction of the column 23, there is an open space 29 defined within the column.
The support head 15 comprises an inner ring structure 31 adapted for displacement along the column 23 while being fixed against rotation with respect thereto, and an outer hub structure 33 rotatably supported on the inner ring structure 31.
The inner ring structure 31 is mounted on the column 23 for guided rolling movement therealong. Specifically, the inner ring structure 31 comprises a peripheral frame 35 of generally circular construction extending around the column 23. A plurality of sets of rollers 37 are mounted on the frame 35 in two groups spaced one with respect to the other in the longitudinal direction of the column 23. The roller sets 37 in each group are circumferentially spaced around the column 23, with each roller set 37 corresponding to one of the longitudinal elements 25 of the column 23. Each roller set 37 comprises two rollers 39 positioned for rolling engagement against respective outer adjacent faces 27, 28 of the corresponding longitudinal element 25, as best seen in Figure 4. This is achieved by supporting the rollers 39 in each set with their axis of rotation substantially at 90 degrees with respect to each other. With this arrangement, the respective longitudinal element 25 defines a track and the faces 27, 28 define two track surfaces, with each roller 39 in the roller set 37 engaging a respective one of the track surfaces. The orientation of the two rollers 39 in each roller set 37 and also the track surfaces, ensures that the ring structure 31 is supported for guided rolling movement along the column 23 while being restrained against rotation around the column.
The hub structure 33 comprises a hub frame 41 of generally circular construction rotatably mounted on the ring structure 31, and a plurality of outriggers 43 extending from the hub frame 41.
A canopy covers the hub structure 33. The canopy 45 is shown partly cut-away in Figures 2 and 3.
A first drive means 51 is provided for rotating the hub structure 33 with respect to the ring structure 31, thereby rotating the hub structure 33 with respect to the column 23. The drive means 51 comprises an electric motor 53 and a drive wheel 55 drivingly connected to the motor 53. The electric motor 53 is supported on the inner ring structure 31 and the drive wheel 55 is in driving engagement with a drive ring 57 mounted on the hub frame 41. In this embodiment, the drive wheel 55 comprises a rubber wheel which is adapted to frictionally engage the drive ring 57, whereby rotational torque applied to the drive wheel 55 is transmitted to the hub structure 33 through frictional engagement between the drive wheel 55 and the drive ring 57 mounted on the hub frame 41.
A second drive means 61 is provided for displacing the support head 15, and thus the hub structure 33 forming part thereof, along the column 23. The second drive means 61 comprises a cable and pulley system 63 from which the support head 15 is suspended, together with a counter-weight 65 and a winch mechanism 67.
The cable and pulley system 63 comprises a plurality of cables 71 (there being four such cables in this embodiment). One end of each cable 71 is attached to the ring structure 31 of the support head 15 and the other end of each cable is connected to the counter-weight 65. Each cable 71 passes over a respective pulley 73 mounted on the column 23 at a location above the uppermost extent of displacement of the support head 15. From the connection to the support head 15, each cable 71 passes upwardly to be routed around its respective pulley 73 and then extends downwardly to the counter-weight 65. The counter-weight 65 is connected to the winch mechanism 67 by way of a winch cable 75. The winch mechanism 67 incorporates a winch drum 68 about which the winch cable 75 can be wound and unwound.
The counter-weight 65 is selected such that the support head 15 can travel downwardly under the Influence of gravity, with its weight parity being compensated by the counter-weight 65. The rate of descent of the support head 15 on the column 23 is controlled by the rate at which the winch cable 75 is unwound from the winch mechanism 67. The winch mechanism 67 incorporates a disc brake (not shown) operation of which can regulate the rate at which the winch cable 75 is unwound.
Operation of the winch mechanism 67 to wind the winch cable 75 about the winch drum pulls the counter-weight 65 downwardly thereby pulling the support head 15 upwardly through the cable and pulley system 63.
The counter-weight 65 is accommodated within the open space 29 within the framework defining the column 23. This provides for compactness of construction and also allows the longitudinal elements 25 within the column 23 to be used for the purposes of guiding movement of the counter-weight as it moves upwardly and downwardly corresponding to displacement of the support head 15. To this end, the periphery of the counter-weight 65 is configured so that the counter-weight can be accommodated within the open space 29 for guided movement therealong by the longitudinal elements 25.
Compactness of construction is further achieved by positioning the winch mechanism 67 on the base 21 and also within the open space 29 defined by the column 23.
Accordingly, both the counter-weight 65 and the winch mechanism 67 are accommodated within the confines of the tower 11.
The riders 17 are accommodated in rider carriers 81 which are suspended from the outriggers 43 by way of the flexible suspension links 19. Each flexible suspension link 19 comprises a flexible line 83 which in this embodiment is in the form of a cable or chain, with one end of the flexible line 83 being connected to a respective one of the outriggers 43 and the other end of the flexible link 83 being connected to a respective rider carrier 81.
In this embodiment, the rider carriers 81 comprise harness structures in which the riders 17 can be accommodated. Other types of rider carriers are of course possible, including carriages in the form of seats or pods accommodating one or more riders.
While the harness structures defining the rider carriers 81 in the embodiment each accommodate a single rider, It is possible to utilise a tandem or other multiple harness in which several riders may engage in the thrill of riding together in a common carrier.
The connection between each suspension line 83 and its respective rider carrier 81 may incorporate a swivel to permit the rider to twist around an axis corresponding to the longitudinal extent of the suspension line. In this way, the rider has the option of twisting or otherwise manipulating his or her body around in order to provide further variety to the ride and thus enhance the sensation experienced during the ride.
Operation of the ride according to this embodiment will now be described. The ride commences with the riders 17 at ground level or at an appropriate loading station near ground level, as shown in Figure 5a. The support head 15 is lowered by operating the winch mechanism 67 to unwind the winch cable 75 from the winch drum 68. Once the support head 15 has been lowered sufficiently so that the riders 17 can be accommodated in the rider carriers 81 and appropriately secured in position, the winch mechanism 67 is operated to wind in the winch cable 75, thereby pulling the counter-weight 65 downwardly and thus causing the support head 15 to move upwardly along the column 23, as illustrated in Figure 5b. During the upward ascent, and once the riders 17 are sufficiently clear of the ground or loading station as well as any other obstacles, the first drive means 51 can be actuated so as to cause the hub structure 33 to rotate about the column 23. This causes the riders 17 to swing outwardly on the suspension lines 83 and move through a somewhat circular path around the column 23, also as shown in Figure 5b. During the ride, the support head 15 can be lowered as Illustrated In Figure 5c and raised as illustrated in Figure 5d in order to change the elevation of the riders as they move through the circular path about the column 23. The speed of rotation of the hub structure 23 can also be varied if desired to provide variation to the ride characteristics. Typically, the hub structure 33 rotates at about 10rpm in this embodiment The displacement of the support head involving movement upwardly and downwardly during the ride may be at speeds up to about 5m/s.
During the ride, the support head 15 can be lowered at a rate faster than the riders 17, thus providing situations where the riders 17 may be higher than the points at which they are attached to the ride.
The variation in elevation during the revolving motion of the riders provides an exciting ride, particularly when regard is had to the significant height at which the ride is conducted. Further variation is available to the riders 17 during the ride through swivelling movement at the connection between the suspension line 83 and the rider carrier 81. To complete the ride, the support head 15 is lowered so as to return the riders 17 to the ground or loading platform.
Referring now to Figures 6 to 10 of the drawings, there is shown an amusement ride 100 according to an embodiment of the invention. The amusement ride 100 is similar in many respects to the amusement ride 10 according to the preceding embodiment and corresponding reference numerals are used to identify similar parts.
The tower 11 comprises a base 21 and a column 23, as was the case in the preceding embodiment. In this embodiment, the base 21 comprises a plurality of legs 101 extending radially outwardly, with anchoring pads 103 provided on the outer ends of the legs 101 for engagement with the ground 13. The base 21 also incorporates a station 105 at which riders are loaded onto, and unloaded from, the ride. The station 105 comprises a platform 107 which extends around the tower 11 and which is accessible by way of stairs 109.
The base 21 also incorporates a portion 111 extending downwardly, accommodated within a hole 113 formed in the ground.
The column 23 is of framework construction and is formed in column sections 115 connected one to another at junctions 117.
In this embodiment, the rider carriers 81 comprise chair structures 119 which may be fitted with an appropriate restraint system for the purposes of restraining riders in position during operation of the ride.
The flexible suspension link 19 suspending each rider carrier 81 to a respective outrigger 43 comprises a pair of flexible lines 121 such as cables or chains. The flexible lines 121 are connected at their upper end to a crossbar 123 which in turn is connected to the respective outrigger 43 by way of swivel connection 125.
Operation of the amusement ride 100 according to this embodiment is similar to that of amusement ride 10 according to the preceding embodiment, with the ride commencing with the support head 15 lowered into a position at which riders can enter the chairs 119 at the station 105, as shown in Figure 8 of the drawings. The support head is then raised into an operative condition and rotated and displaced in a similar fashion to the preceding embodiment.
In this embodiment, all chairs 119 are accommodated at the station 105 at the same time. Thus, riders enter and leave the various chairs 119 at the station at the same time.
In an alternative arrangement, the station may be at a specific location, with the chairs 119 moving sequentially into and out of the station. With such an arrangement, the drive means for rotating the support head 15 can be utilised to rotate the chairs in an indexing fashion, with the chairs moving into and out of the station one after another. This can be advantageous in that the ride operator would than be in a better position to exercise control over the loading and unloading process, particularly with regard to the manner in which riders enter and leave each chair.
The amusement ride 100 according to this embodiment has been designed so that it is conducive to construction on a very large scale. Indeed, the tower 11 is approximately 60 metres in height and the diameter of the rotatable support head 15 is approximately 18 metres. The enormous size of the amusement device ensures that the riders are exposed to an extreme height during the ride, thereby enhancing the sensation experienced during the ride.
Referring now to Figure 11, there is shown a rider carrier 81 and a flexible suspension link 19 for an amusement ride according to a further embodiment. The flexible suspension link 19 comprises two lines 131 suspended from a cross member 133 connected by pivot connection 135 to outrigger 43. The pivot connection 135 facilitates outward swinging motion of the rider carrier. The rider carrier 81 comprises a capsule 141 in which several riders can be accommodated. The capsule 141 incorporates seating 143 for riders in the capsule. The capsule 141 is rotatable supported between two trunnions 145, with each trunnion 145 being connected to one of the lines 131. With this arrangement, the trunnions 145 define a rotational axis about which the capsule 141 can rotate. The capsule 141 has an outer periphery fitted with control devices in the form of a pair of vanes, not shown in Figure 11. The vanes cause the capsule 141 to rotate about the rotational axis upon movement of the capsule through the air with rotation of the hub structure 33. The angle of attack of the vanes determines the speed of rotation of the capsule. The direction of rotation may be altered by altering the attitude of the vanes; that is, by facing them in an opposite direction relative to the rotational axis of the capsule. There may be provision for a rider to selectively move one or both of the vanes for the purposes of controlling the direction and speed of rotation of the capsule. The control may be achieved by way of a lever mechanism located within the capsule 141 and operatively connected to one or both vanes. This presents the rider with an opportunity to control his or her own ride, thereby providing variation to the ride and further enhancing the sensation experienced on the ride.
There may also be provision for locking the capsule 141 against rotation during the ride. The locking mechanism may be controlled by the ride operator who may provide the rider with the choice as to whether or not the rotational function will be employed during the ride.
The rotatable capsule provides a further axis of rotation during the ride, providing variety and thus a generally more exciting ride. The feature may also be conducive to repeat business, as riders may wish to develop their skills over time in controlling the ride.
From the foregoing, it is evident that the illustrated embodiments of the present invention provides an amusement ride involving one or more riders being conveyed through the air but with the possibility of sufficient variation to provide an exciting ride conducive to riders returning for further rides.
The amusement ride according to the illustrated embodiments of the invention can be constructed on a large scale such that the riders are elevated to a height which in itself provides excitement. The amusement ride is of a design which is conducive to construction on such a large scale. It incorporates a simple yet highly effective arrangement for driving the support head 15 both rotationally for moving the riders around through the air, and also linearly for varying the elevation of the riders during the ride as well as raising and lowering the riders with respect to the ground or a station at which the riders embark upon, and disembark from, the ride.
Throughout the specification, unless the context requires otherwise, the word "comprise" or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
