Amusement rides with tracks on towers are known in the art. Also known from prior application WO2012/162675 by Applicant is a roller coaster mounted on a tower. Mounting the track mainly on the exterior of the tower (which is done to allow the interior of the tower to function as both the “up” section of the track and contain elevators, evacuation stairs and other equipment to allow the top of the tower to have a useable retail/dining/viewing area) limits the possible maneuvers the track can be designed to preform because there is a strict limit to the distance out from the support pillars the track can be mounted. However, mounting the track around the exterior of the tower creates the problem that all of the direction of rotation of the track around curves is in the same direction, potentially increasing motion sickness in riders. Although the tracks can be “stacked” at least two tracks deep out from the pillars without additional support from below, it is difficult for the path of the track to cross over itself too often so long as the track is mounted solely on the exterior of the tower. When the track is mounted solely on the exterior of the tower, the track all has to remain within a roughly cylindrical space around the tower defined by the support pillars on the inside and the maximum distance the track can be out from the tower on the outside.
Due to the length of the upward track, standard chain drives used on most rollercoasters could not be used, as the weight of the chain would have created too many problems. However, the height of the ride requires a very safe drive system. Chain drives and associated sprockets are very noisy; making the ride unsuitable to put into many environments that one might wish to put a ride with such a small footprint, such as a shopping area. Chain drives also require lubrication, which will possibly drip on the riders. Chain drives are subject to more wear that the proposed system.
The foregoing example of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those of skill in the art upon a reading of the specification and a study of the drawings.
One aspect of the present disclosure is to have roller coaster track mounted on a tower that reverses direction of travel (and therefore rotation) around the exterior of the tower while maintaining the safety and comfort of the riders.
Another aspect of the present disclosure is to provide a direction reversing turn that maintains sufficient G force to ensure riders a pressed into their rider supports
Another aspect of the present disclosure have a direction reversing turn that can be traveled in either direction, allowing for either a drop of overall location on the tower to allow the riders to end up on a track located higher up the tower than at the beginning of the turn.
Another aspect of the present disclosure is to provide a direction reversing turn that does not invert the riders during the turn.
Another aspect of the present disclosure is to occasionally reverse direction of rotation around the tower to try to reduce potential motion sickness of the riders.
Another aspect of the present disclosure is to occasionally reverse direction of rotation around the tower to make the ride more interesting and thrilling.
Another aspect of the present disclosure is to provide a drive system for the internal spiral up track
The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tool and methods which are meant to be exemplary and illustrative, not limiting in scope. In various embodiments, one or more of the above described problems have been reduced or eliminated, while other embodiments are directed to other improvements.
One embodiment is a drop turn where the track is headed a first direction around on the outer perimeter of the tower, turns downward and banks about 180 degrees towards the tower while the track drops and turns about 180 degrees to end up traveling a second direction around the perimeter of the tower, the second direction being substantially opposite the first direction.
Another embodiment is a drop turn where the track is headed a first direction around on the outer perimeter of the tower, turns downward and banks about 180 degrees away from the tower while the track drops and turns about 180 degrees to end up traveling a second direction around the perimeter of the tower, the second direction being substantially opposite the first direction.
Another embodiment is a loop turn where the track is headed a first direction around on the outer perimeter of the tower, turns upward and then drops while banking about 180 degrees toward the tower to end up traveling a second direction around the perimeter of the tower, the second direction being substantially opposite the first direction.
Another embodiment is a loop turn where the track is headed a first direction around on the outer perimeter of the tower, turns upward and then drops while banking about 180 degrees away from the tower to end up traveling a second direction around the perimeter of the tower, the second direction being substantially opposite the first direction.
In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.
Before explaining the disclosed embodiment of the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the particular arrangement shown, since the invention is capable of other embodiments. Exemplary embodiments are illustrated in referenced figures of the drawings. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than limiting. Also, the terminology used herein is for the purpose of description and not of limitation.
All references to the direction of the track contained herein are in reference to the direction of travel of the rider carriages in normal operation of the ride. Along and/or down the track means the rider carriage has moved along the track in the normal direction of travel and does not refer to an actual drop in height from the ground of the rider carriage. The degree of bank of the track refers to the rotation of the track plane formed by the first and second rail around the spine rail from starting position at a loading station (not shown). At most loading stations the first rail 106 and the second rail 107 are in the same horizontal plane with each other and substantially level with the ground in the normal loading configuration. This position is 0 degree bank. Note that 0 degree bank will not always have the riders in an upright position because the track itself can be at orientations other than level. The orientation of the ride is dependent on both the orientation of the track and the degree of bank. Right and left bank are relative to the rider loaded in the rider carriage facing forward in the direction of travel of rider carriage. A 45 degree left bank is describing the plane of the track being at 45 degrees on the left side of the spine rail. The turns disclosed herein will be described in term of the depicted embodiments. As long as the configuration of the turns is maintained, the exact degrees of bank the track rotates through and/or the starting and ending degrees of bank of the track are not limited to the depicted embodiments. In practice, many variations of the position of the rider carriage, including variations of the starting bank and turn position of the track and ending bank and turn position of the track will be used in practice, as it is desirable for the riders to have a number of different experiences with turns and it is expected that there would be multiple turns on a given track to change the direction of travel around the tower multiple times for the riders. Additionally all of the G forces described herein are based upon calculations done with simulators. The G forces are estimates for the purposes of description and no variations of actual G force encountered in an actual ride indicate a failure to practice the described turns.

The drop turn 201 starts with the rider carriage at a first position 202 on track 101. The rider carriage is traveling is a first direction indicated by arrow A around the circumference of the tower along the track 101. The track has a 45 degree right bank at the first position and a rider traveling at 15 MPH would experience about 1.5 G in the depicted embodiment. The rider carriage 105 travels down the track extending along other upper part of the C to a second position 203 where the track 101 starts to turn downward at the upper curve of the C as best seen in
The rider carriage then travels down the track 101 extending to a fourth position 205 about two thirds of the way down the spine of the C as best seen in
The track then extends down the track to a fifth position 206 at the lower curve of the C. The track has rotated 30 degrees from position four, resulting in 0 degree bank in the depicted embodiment. In the depicted embodiment a rider traveling at 40 MPH would experience about 3.5 Gs. The rider carriage then travels down the track extending to a sixth position 207 located on the lower arm of the C. The track is on headed and rider carriage is now traveling in a second direction indicated by arrow B around the circumference of the tower, which is substantially opposite the first direction. The degrees of bank at any given location can be varied depending on the desired rider experience.

The loop turn 710 starts with the rider carriage at a first position 701. The rider carriage is traveling is a first direction around the circumference of the tower indicated by arrow E. In the depicted embodiment at the first position 701 the track is at a 60 degree bank right and a rider traveling at 40 MPH would experience approximately 3.5 Gs of force. The rider carriage travels along the track to a second position 702, where the track starts curving upward, the track extends upward past third location 703 to forth location 704 which is at approximately the highest point of the loop turn. It is to be understood that this is not the highest point of the overall track, merely the highest location on this particular turn. At the fourth location 704 the track has banked 60 degrees right from the orientation in position 701. At the fourth location 704 at rider going 20 MPH will experience about 1.5 Gs of force in the depicted embodiment.
The track 101 then curves downward to fifth location 705 where the rider carriage 105 is a 160 degree bank right. A rider traveling at 30 MPH would experience about 1.5 Gs. The track 101 then extends downward to sixth location 706. The track as rotated about 20 degrees right to be at 0 degree bank at location 706. The track continues along the bottom side of the tear drop to seventh location 707. The rider carriage is now moving in a second direction around the circumference of the tower indicated by arrow F which is substantially opposite the first direction. The track continues to position 708 where the track is banked 60 degrees left in the depicted embodiment. A rider traveling at 45 MPH would experience about 3.5 Gs at position 708 in the depicted embodiment.

The loop turn 810 starts with the rider carriage at a first position 801. The rider carriage is traveling is a first direction around the circumference of the tower indicated by arrow I. In the depicted embodiment at the first position 801 the track is at a 60 degree bank left. The rider carriage travels along the track to a second position 802, where the track starts curving upward, the track continues upward past third location 803 to forth location 804 which is at approximately the highest point of the loop turn. It is to be understood that this is not the highest point of the overall track, merely the highest location on this particular turn. The track 101 then curves downward to fifth location 806. The track 101 then continues downward to sixth location 806. The track as rotated to be at 0 degree bank at location 806. The track continues along the bottom side of the tear drop to seventh location 807. The rider carriage is now moving in a second direction around the circumference of the tower which is substantially opposite the first direction indicated by arrow J. The track extends to position 808 where the track is banked 0 degrees in the depicted embodiment.
The velocity, bank angle and G-force through the loop turn will vary based upon the tower diameter. The drop can occur with or without braking. The banking roll can occur towards the tower with 180 degrees of bank transition, or by rolling away from the down with 180 degrees of bank transition. The loop can also be run in reverse direction from the depicted embodiment, with the rider carriage ending up higher than it started without the rider carriages being powered upward. Further exactly where in the overall loop turn the banking occurs in not important. In order to complete the maneuver safely and to have the track mounted solely on the exterior of the tower, the track must bank transition through a total of about 180 degrees towards the tower, or through a total of about 180 degrees bank transition away from the tower.
As mentioned above, the height of the tower and the helical configuration of the upward track on the tower of the depicted embodiments make standard chain drive impractical. This is also true for a viewing ride mounted on a tower with a helical upward track 111, send in
Referring next to
Along the helical upward track 111, the wire rope 901 is guided by rotating guide sheaves 910 that are integral to the track structure and spaced at regular intervals along the track. Sheaves 910 may be mounted to the track structure, such as the cross ties and strong back, or may be mounted to the track support structure. The wire rope 901 is strung between the regularly spaced guide sheaves 910, and follows a faceted path with straight sections between the guide sheaves 910 with the wire rope resting in grooves 913 around the sheaves. The path between any two grooves must always be a straight line Is this correct?). The wire rope must be under sufficient tension to force wire rope in the grooves 913 so that the groove of the sheaves 910 holds the wire rope up against gravity and in the desired path. In order for the tensioning to work, the overall path of the wire rope must be either substantially circular in a horizontal plan, or substantially cylindrical. The exact spacing of the drive sheaves 901 and the amount of tension that the wire rope will need to be under will depend on the radius of the turns of the helical track 111 and the amount of upward incline. The wire rope 901 and guide sheaves 910 are positioned at approximately the same elevation as the track rails 106, 107, as seen in
As shown in

The cams surfaces are positioned such that control arm 907 is moved, causing the arm to pivot at 906 to open the clamping grip 902. The position of the grip-controlling cams 914 are such that the clamping grip opens or closes approximately at the position same where the natural paths of the gripping surfaces 908, 909 of the mechanical grip and the wire rope intersect, thus minimizing the relative motion between the wire rope and the gripping surfaces on the mechanical grip and allowing the rider carriage 105 to attach or detach from the wire rope 901.
In the depicted embodiment, the wire rope forms a continuous circuit, recirculating through a system of guide sheaves and motorized drive sheaves. On upward section of the roller coaster version, the wire rope follows the upward helical track and then drops directly down to the bull wheel at the bottom of the down. In the viewing tower version, the wire rope runs the whole track, both up and down in the depicted embodiment. This allows the weight of the descending rider carriages to balance the weight of the ascending rider carriages, putting less strain on the wire rope drive system. Another possible embodiment would be to have two separate wire ropes, one for the ascending track and one for the descending track.

Alternatively, the wire rope may be propelled by multiple drive sheaves 2401 distributed along the path of the wire rope, as seen in
