Amusement ride ingress-egress system

Abstract: An ingress-egress system for an amusement ride of the type utilizing a movable cabin (2) operating within an enclosure structure (4) comprises a plurality of first ingress doors (24) located on a first surface of said cabin (2), the ingress doors (24) being aligned with ingress paths (30) in said cabin (2); a plurality of first egress doors (32) located on a second surface of the cabin (2), the egress doors (32) also being aligned with access paths (30) in the cabin (2); a movable ingress platform (22) having a retracted position outside of the operating envelope (14) of the cabin (2) and a deployed position aligned with the first ingress doors (24) when the cabin (2) is in a loading position; a movable egress platform (40) having a retracted position outside the envelope (14) of motion of the cabin (2) and a deployed position aligned with the first egress doors (32) when the cabin (2) is in a loading position; a plurality of second ingress doors (18) in the enclosure (4), the second ingress doors (18) being aligned with the ingress platform (22) when the ingress platform (22) is in its deployed position; a plurality of second egress doors (34) in the enclosure (4) aligned with the egress platform (40) when said egress platform (40) is in its deployed position; restraint means to restrain the passengers in their seats (12) when the cabin (2) is in motion; and means (16) to coordinate actuation of the doors, platforms and restraint means. The system affords rapid ingress and egress to the cabin (2) after it has come to a loading position and prevents deployment of the ingress-egress system and release of the restraints when the cabin (2) is in motion.

Description: Amusement rides that utilize passenger cabins which are capable of movement with multiple degrees of freedom (roll, pitch, yaw, vertical, lateral and longitudinal motion) have recently become popular due to their ability to provide exciting rides in relatively small areas. US-4,066,256 discloses an example of such an amusement ride. However, such amusement rides present many difficulties associated with their safe operation and economics. Previous amusement rides that utilized tracked vehicles used loading facilities which incorporated loading platforms located in a designated loading area adjacent to the tracks upon which the vehicle runs. Such a system utilizes direct access of the patron into the movable vehicle by allowing the patron to step directly into the vehicle when it is brought to rest in the loading area. Thereafter, the operator of the ride manually assures that safety systems, such as seatbelts and other restraints, are engaged prior to departure of the vehicle from the loading platform area. Similarly, non-tracked rides such as ferris wheels and other rotary or oscillating rides have utilized a waiting area and loading zone to which the passenger vehicles are progressively brought, stopped and loaded. While such access systems have proven useful and practical for a wide variety of relatively simple rides, they are relatively limited in their applicability due to the fact that the vehicle must be brought to a slow and controlled stop next to the boarding platform on which the next load of patrons is waiting. However, the stationary loading platform approach is not readily applicable to non-tracked vehicles that must operate at high speed in close proximity to the platform, especially if such vehicles are capable of movement in a direction lateral to the loading platform. The adaptation of multiple degree of freedom motion simulators as a basis for amusement rides has presented a variety of problems, among them rapid, economical and safe means of providing access by patrons to the ride. Amusement rides which use cabin vehicles that are maneuvered in multiple degrees of freedom must be enclosed within a structure which prevents access to the operating envelope of the vehicle by patrons or other unauthorized persons in order to prevent the risk of severe injury which would occur should a person be trapped within the operating envelope of the vehicle once the ride has begun. Large cabin vehicles of the type that are utilized in theme parks and other major attractions present enormous risks in that the potential force and velocity of the rides cannot be overcome by any human force and, once set in motion, are not susceptable to immediate cesation of all motion when operating at high speed without injury to the operators, structure, occupants, or some combination thereof. Furthermore, such moving cabin rides represent a very large investment due to their use of hydraulic and electronic power systems and their extensive use of advanced technology, including computers. Such systems were developed, in part, from simulators used to train pilots and other operators of expensive vehicles, primarily to avoid the risks associated with losing such an expensive vehicle during experimental or training exercises. For that reason, rapid ingress and egress of a large number of passengers was neither necessary nor desirable, since the simulator could only be effectively and economically used by a relatively small number of people over a relatively large period of time, and the simulator was much less expensive to use than the aircraft or other vehicle being simulated. The first uses of such moving simulators as amusement rides incorporated the simple door and access plank developed for the simulators, but the economics for such an installation were not justifiable to major theme parks in light of the relatively limited space available for such systems, the cost of the equipment and physical plant associated with the installation and the probability of client alienation associated with excess wait time to enjoy the attraction. Furthermore, the relatively simple loading systems available for amusement rides could not be adapted to the simulator based systems, since the operating enevelope of the simulator could not be intruded into, and such systems as were available were all deficient in providing high capacity access without interfering with the operating envelope. For these reasons there remains a need for a rapid, economical, safe and relatively high capacity ingress-egress system for a moving cabin and other high energy, high coat amusement rides that present the above requirements. Ingress-egress systems for amusement rides must provide rapid and easy access to the ride in a carefully controlled environment and still prevent unnecessary risk of harm to the patron. When these requirements are combined with the use of a large moving cabin simulator that is capable of movement in six degrees of freedom, with the resultant large envelope which must be cleared prior to activation of the simulator, conventional and simple methods of access to such amusement rides become impractical. Furthermore, reliance upon a human operator to determine that seat belts or other restraints are physically engaged prior to activation of the moveable cabin, which can produce high accelerations about all axes, is insufficient to guarantee safety of the patron during the ride. The damage which may occur in the event that a partial failure or differential activation of the access system were to occur emphasizes the fact that simple patron access systems of the type previously used for such amusement rides are inadequate in today's environment of higher cost effectiveness and safety requirements. Furthermore, the great cost of multiple degree of freedom simulators to be used as amusement rides justifies a higher capacity access system, even though it may be more complex and costly than a simple system. During 1987 there was disclosed in the United States by public use a system for providing passenger ingress and egress in an amusement ride having a passenger cabin movable within an operating envelope and an enclosure outside the operating envelope, said system comprising: a plurality of first doors arranged on surfaces of said cabin, said doors providing access to ingress and egress paths within said cabin; a plurality of second doors arranged on surfaces of said enclosure, said second doors being substantially in alignment with said first doors when said cabin is in a loading position; retractable bridge means movable between a deployed position in which the bridge means provide access between the first and second doors and a retracted position in which the bridge means are retracted outside of the operating envelope; and control means for controlling and coordinating the opening of said first doors and said second doors and the retraction and deployment of said bridge means so as to enable rapid passenger ingress and egress to and from said cabin when said cabin is in said loading position. Such a system is described below with reference to Figures 1 to 5 in which a retraction mechanism operates a cable drum that winds cable over a series of sheaves to retract or deploy a bridge between deployed or retracted positions. A system in accordance with the present invention is characterised by the bridge means comprising a substantially horizontal platform within said enclosure having one end connected to said enclosure under said second doors and a free end located outside the operating envelope of said cabin; and a bridge pivotally connected to the free end of said platform and having pivoting means operable to pivotally move the bridge between a retracted position in which said bridge is pivotally retracted against said enclosure and above said platform outside the operating envelope of said cabin and a deployed position in which said bridge is pivoted away from said enclosure to provide access from said platform to said cabin through said first and second doors when said cabin is in said loading position. In a preferred embodiment of the present invention a combination of high speed retractable access platforms is combined with a door configuration in the cabin and enclosure structure, and interlocking control systems for the door platforms and restraint systems that provide previously unavailable levels of patron throughput and safety for multiple degree of freedom moving base amusement rides. Preferably, a plurality of doors is arranged on opposite sides of the cabin at each end of the aisles adjacent each row of seats in the cabin. The doors are activated by a control system that coordinates their opening with the deployment of high speed movable access bridges that are retracted beyond the operating envelope of the moving base amusement ride when it is in operation. In a preferred embodiment, the floor of the amusement ride is either stepped or sloped downwards from back to front to allow unrestricted viewing by the patron of a scene projected in the front of the moving cabin. Each of the access aisles are thus displaced vertically in step-wise fashion from the back of the cabin to the front and their respective access doors are positioned so that their bottom edges are aligned with the surface of the aisle of their respective row. Immediately after the passenger cabin is brought to a rest at the completion of the ride, the bridges are rapidly moved from their rest position outside of the operating envelope of the cabin to a position in alignment with the doors. The bridges are configured so that their respective entry aisles are aligned vertically and laterally with the position of the doors and their associated aisles. When the central ride control computer is provided with sensor information that the access bridges have been positioned in alignment with appropriate indexing positions, the doors are opened and patrons who have enjoyed the ride may move out of the cabin through one set of doors while those entering the amusement ride are granted entrance to the cabin through the doors on the opposite side of the cabin. The movable loading bridges, in turn, are lowered and aligned with the movable cabin and the enclosure doors to create a path for ingress and egress to the cabin via the movable bridges. The doors to the stationary loading ramps outside the enclosure are likewise controlled by the ride control computer and are opened after the movable bridges have come to rest in alignment with the cabin doors and the enclosure doors upon completion of the ride. Thus, after the ride has been completed, the invention provides for a tightly controlled sequence of stopping the passenger cabin, deploying the high speed access bridges and opening the doors in a coordinated fashion after the bridges, cabin and outer doors are properly aligned, thereby allowing the patrons to proceed via the aisles between the seats into and out of the cabin via the ingress and egress doors located on opposite sides of the cabin. After the entering patrons have been seated, a central control system will not allow initiation of the cabin closing sequence prior to the beginning of the ride until all of the passenger restraints for occupied seats are engaged. Thus, the sequence initiating the beginning of the ride can only begin after the passengers are positively restrained. A control panel illustrating the status of the restraints may also be provided so that a human operator may cross check the system operation and ascertain the location of disengaged restraint systems. After the restraint systems are engaged, the operator leaves the passenger cabin and, upon reaching his station outside of the ride enclosure, actuates a switch which begins the closing sequence. The doors to the cabin and to the external bridges are closed; then the high speed retractable loading bridges are retracted out of the operating envelope of the cabin and the ride begins. It may be seen from the above description that the present invention provides a highly automated and efficient means of providing ingress and egress to moving cabin amusement rides while providing a high degree of safety and automation necessary for rides which are capable of rapid motion and multiple degrees of freedom within an enclosed area. In order to increase the inherent safety associated with the invention, failsafe design and redundancy is provided in all of the critical control systems and emergency stop functions are provided in the event of a failure of any critical system. Other features and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings, which illustrate, by way of example, the features of the invention. Figure 1 is a top elevational view of the prior art amusement ride ingress-egress system disclosed by public use in 1987, illustrating the relationship of the passenger cabin, the ride enclosure and the ingress-egress system components; Figure 2 is a cross-section of the ingress-egress system of Figure 1 at 2-2; Figure 3 is a cross-section similar to Figure 2, illustrating the arrangement of the access bridges when they are retracted beyond the operating envelope of the passenger cabin; Figure 4 is a side elevational view at section 4-4 of Figure 2, showing the retraction mechanism for the access bridges; Figure 5 is a side elevational cross-section similar to Figure 4, illustrating the position of the access bridges when they are in their retracted position; Figure 6 is a section at 6-6 of Figure 4 illustrating the rail and guide system for the access bridges in the guide rails in the side of the ride housing; Figure 7 is a section at 7-7 of the guide rail system illustrating the guide rollers and their relationship to the guide rail system; Figure 8 is a section at 8-8 of Figure 6, illustrating the stop locating pad for the access bridge system; Figure 9 is a cut-away elevational view of an access door illustrating the door locking mechanism; Figure 10 is an illustration of the door actuation system as viewed from 10-10 of Figure 9; Figure 11 is an elevation of an amusement ride ingress-egress system in accordance with the present invention utilizing a pivoting drawbridge system; Figure 12 illustrates the drawbridge system of Figure 11 in its retracted position; and Figure 13 is an operational schematic diagram illustrating the relationship of the various electromechanical and electronic portions of an amusement ride according to the present invention. The system described below including the modification of Figures 11 and 12 in accordance with the present invention provides a means of rapid and high volume access to a passenger cabin 2 from the exterior of structure 4 by use of retractable bridges 6 that match with cabin doors 8 and enclosure doors 10 to provide controlled access to patron's seats 12. The cabin 2 is capable of movement in multiple degrees of freedom (roll, pitch, yaw, x,y,z) through operating envelope 14. A ride control computer 16 monitors sensors and controls the safety interlock system that provides the required deployment sequence of the ingress-egress system and prevents the starting of the ride until each passenger that occupies a seat has fastened a safety restraint and the ingress-egress system has been retracted to an area outside the envelope. Thus, the present invention provides the benefits of very high throughput while limiting the potential for damage to the ride, its access system or the patrons. The availability of multiple degree of freedom flight simulators has created the opportunity to provide amusement rides that can expose the passengers to a wide variety of motion cues without leaving a single central facility. When the capability to provide a wide variety of visual cues is included, the potential for such simulators as amusement rides is very promising. However, simulators have generally been designed to provide training for aircraft and other expensive vehicles and most of this training was to be provided to as relatively small number of people who were to use the simulator for a relatively larger period of time. The requirement to rapidly turn over the number of people to use such a simulator for an approximately 5 minute amusement ride created new pressures previously ignored or unrecognised to allow rapid and safe access of the patrons to the passenger cabin during the change over between shows. Since such a simulator is extremely expensive, the entire economics of employing a six degree of freedom simulator as an amusement ride rested with the ability to provide rapid ingress and egress by patrons in a safe and reliable manner. The present invention provides such safe and reliable access without in any way inhibiting the capabilities of the simulator and its use as an amusement ride. Figure 1 is a top plane view of a prior art system illustrating passenger cabin 2 within the ride enclosure 4 with access bridges 6 in place. Cabin doors 8 and enclosure doors 10 are shown opened to the position in which they provide rapid access to passenger seats 12. When retracted, bridge 6 retreats beyond the operating envelope 14 of the simulator, thereby providing a free movement of cabin 2 within its design parameters. As shown by the arrows, access of the patrons is uni-directional from ingress doors 18 along aisles 20 on ingress bridge 22 to ingress cabin doors 24. Access is guided by ingress bridge rails 26 that define the aisles 20 on the bridge 22 and match with aisles 30 between the rows of patron seats 12. Similarly, egress doors 32 in the cabin and enclosure egress doors 34 in the enclosure mate with egress bridge rails 36 to define egress aisles 38 on egress bridge 40. In the sequence of operations according to the invention, the cabin 2 is brought to a rest position at which time bridges 22 and 40 are deployed to a position in alignment with the openings defined by the cabin doors 8 and enclosure doors 10. When the bridges are at the appropriate position and the sensors so indicate, the ride control computer actuates all of the egress doors, thereby providing an egress path for the patrons who have experienced the ride. As soon as practicable thereafter, the ingress doors are opened and the incoming load of passengers is provided access to the cabin preparatory to the ride beginning. When all the entering passengers have been seated and have actuated their seat restraints (not shown here), the status is displayed on a panel for manual verification by the ride operator and, if all safety systems are secured, the ride control computer is allowed to proceed with retraction of the ingress-egress system after the ride operator has indicated to the ride control computer that he is at his station. Thereafter, the ride operator closes the doors and inputs a request to the ride control computer that the ride start. If the ride control computer (RCC) has received information from the appropriate sensors that the ride is safe to begin motion and that all passenger safety restraints are engaged, the RCC then retracts the bridges and begins the ride. Thereafter, the doors are closed and once the doors are closed, bridges 6 are retracted to a position outside of operating envelope 14. The ride control computer is provided an indication that the retraction process is complete and the beginning of the ride is then initiated. Figure 2 is a cross-sectional elevational view showing cabin 2 at its loading rest position in enclosure 4. This loading position corresponding to the position assumed by the cabin when the hydraulic pressure that drives actuators 42 is removed and the weight of the cabin drives the actuators to their collapsed position. When actuators 42 have carried cabin 2 to its rest position, and bridges 22 and 40 have been deployed, doors 18, 30, 32 and 34 are then opened, providing access to cabin 2 in combination with rails 26 and 36. Actuators 42 operate cabin 2 through cabin structure 44, the actuators being supported from a basic structure 46 located in the floor of the enclosure. Bridges 22 and 40 are supported by structure 48 and 50 respectively, thereby providing a rigid and stable structure for ingress and egress of the passengers when the cabin is in its loading position and the access bridges are deployed. Aisle extensions 52 and 54 for the ingress and egress portions respectively, are designed to mate with bridges 22 and 40 to provide a smooth transition from the bridges to the cabin aisles without the necessity of directly interfacing the bridges with the side walls 56 and 58 respectivcely of the cabin structure. Figure 3 illustrates the arrangement of the access bridges after they have been retracted to positions outside of the operating envelope 14 of the passenger cabin 2. Here, passenger cabin 2 is illustrated in the rest loading position in which actuators 42 have drawn down to their minimum height based on structure 46 and operating through cabin structure 44. It may be seen that the ingress and egress aisle extensions 52 and 54 remain attached to the cabin 2 and project from the cabin walls 56 and 58. Ingress structure 48 and egress structure 50 retract with the bridge as a unit when the bridge is pulled to its upper extremity in the retraction process. Figure 4 is a side elevational view at 4-4 of Figure 2 and illustrates egress bridge 40 in its deployed position. In this illustration, enclosure egress doors 34 are shown closed rather than deployed against egress bridge rails 36. Egress structure 50, shown here partially eliminated for the sake of clarity, supports egress bridge 40 away from the enclosure wall. A retraction mechanism generally designated 60 incorporates a drive system 62 which operates a cable drum 64 that winds cable 66 over a series of sheaves 68 to thereby retract or deploy bridge 40 between its deployed or retracted positions. Figure 5 illustrates the bridge 40 retracted to its position outside of the operating envelope by use of retraction mechanism 60 incorporating drive system 62 driving cable drum 64. As previously described, cables 66 are then wound around cable drum 64 and retract bridge 40 and supporting structure 50 to a retracted position when the cables 66 are wound over sheaves 68. As may be seen from this view, by use of this mechanism the bridge structure may be completely withdrawn, leaving as the only obstruction the side wall of the ride housing. Figure 6 illustrates the mechanism by which the structure 50 and bridge 40 interface with guide rail 70 of ride housing 4. Figure 6 is a section at 6-6 of Figure 4 and shows that the structure interfaces through a vertical member 72 that incorporates rollers, generally designated 74, and a stop locating pad 76 to provide for accurate translation of the bridge 40 between its deployed and retracted systems. Figure 7 illustrates the arrangement of rollers 74 as they ride against guide rail 70. The upper roller 78 bears against surface 80 on guide rail 70, thereby preventing motion of the vertical member 72 inward into the enclosure. Similarly, roller 82 varies against surface 84 on guide rail 70 to prevent lateral motion of the structure relative to the vertical guide rail 70. Both rollers are mounted upon bearings 86 that are attached to vertical member 72 of structure 50. Figure 8 illustrates a cross-sectional view of locating pad 76, illustrating how the male portion 88 of vertical member 72 fits into a mating female portion 90 mounted to the floor 92 of enclosure 4. Thus, when the structure of the bridge 40 is in its deployed position, the bridge is positively located by locating pad 76. Figure 9 is a cut-away view of a door 8 of the type used in the present invention. The latch mechanism, generally designated 94, incorporates a linear actuator 96 that directly operates a locking pin 98 and operates a second locking pin 106. Locking pins 98 and 106 respectively interface with jamb plates 109 and 110 to lock the door when actuator 96 is engaged. Door 8 pivots about hinge 112 and is opened and closed by an actuator system generally designated 114. Figure 10 illustrates the actuation means to open and close the door. As discussed above, hinge member 118 is attached to door 8 by structural extensions 120. Lever arm 122 is fastened to hinge member 118 and is moved by linear actuator 124 in response to air admitted through fittings 126 which drive actuation rod 128 in a linear direction, thereby rotating the doors open and closed. Figure 11 illustrates a modification to the above system constituting an embodiment of the present invention in which bridge 22 is pivotally retracted against the walls of enclosure 4 rather than being withdrawn vertically. Here, the relationship of rails 26 and pivot point 130 are arranged so that when the bridge is retracted, the rails 26 will not interfere with one another, nor will there be interference between any other portions of the bridge structure and the remaining structure within the enclosure or attached to the cabin. An actuator 132 pivotally attached to the wall at pivot point 134 and bridge structure 22 at the pivot point 136 is actuated to effect rotation of bridge 22 about pivot point 136 after ingress doors 18 and 30 have been closed. In the deployed position bridge 22 forms an extension of platform 138 and ingress aisle extension 52 to complete the access required to the cabin. Figure 12 illustrates bridge 22 in its retracted position against the outside wall after linear actuator 133 has been extended to pivot bridge 22 around pivot point 130. Thus, the bridge 22 has retracted outside of operating envelope 14 to provide free movement of cabin 2 throughout its operating range. Figure 13 illustrates a functional schematic of the electrical interfaces of the various basic components of the ingress-egress system with the ride control computer 16. The ride control computer 16 provides the primary means of controlling the door actuating sub-system 130, which incorporates both systems required to open and close the doors and the sensors required to provide the appropriate signals to the ride control computer that the doors are in position. Similarly, the ingress and egress bridge system 132 incorporates both an ingress bridge lift system 134 and an egress bridge lift system 136. Provision is made for mutual operation of the lifts when the ride is not in use. An operator control console 140 is provided to allow the operator to interface with the ride control computer and to observe the interior of the cabin through the onboard surveilance camera 142. A similar control console 144 is provided for the tower operator, who acts as a backup observer. The monitor system monitors the Ride Control Computer(s) and generates fault messages for operations assistance and maintenance trouble-shooting. A hard copy printer 152 is provided to allow for the recording of the messages of the results of specific events during the ride. An uninterruptible power supply 154 is provided to assure that any interruption in the normal power supply to the ride control computer and the other systems will allow the drive system to safely shut down the ride. The system safety sensors 156 provide input to the ride control computer to provide a positive indication that all doors are closed and occupied seat restraints are latched prior to initiation of the ride. Thus, the ride control computer sequences the deployment of the ingress and egress bridges prior to the opening of the access doors that meet with the bridges. After the doors have been opened to meet with deployed ingress and egress bridges and the passengers have taken their seats, the doors are closed by the operator and the bridges are retracted to their safe positions outside of the operating envelope of the ride cabin. Thereafter, the system safety sensors provide input to the ride control computer that all doors have been properly closed and bridges have been retracted and the passenger restraints are latched for the occupied seats. When the operator manually requests a ride start and the Ride Control Computer determines that it is safe to do so, the ride control computer can begin the amusement ride. While those skilled in the art will appreciate that a variety of programs and computers may be used to achieve the results required of the ride control computer 16, a practical embodiment of the present invention incorporates the use of a double redundant programmable controllers. Those skilled in the art will appreciate that a variety of computers and programming languages may be used to provide the sequences of operation and the safety interlocks described above. From the above it may be seen that the present invention provides a highly safe, reliable, efficient and economical means of rapidly accessing a moving base simulator used as an amusement ride.
