Description

Technical Field

[0001] [Cross - Reference to Related Applications] This application claims priority and the benefit thereof based on U.S. Provisional Patent Application Serial No. 63 / 106,944, entitled "MULTI - SEGMENT MOVABLE RAILING ASSEMBLY", filed on October 29, 2020, which is hereby incorporated by reference in its entirety.

[0002] The present disclosure generally relates to multi - segment movable railing assemblies.

Background Art

[0003] Some amusement park rides include a movable vehicle suspended from a track. Below the vehicle, one or more platforms can be arranged along some parts of the ride to facilitate the exit of passengers in case the movement of the vehicle unexpectedly ends. For example, if the vehicle suddenly stops while on the platform, an operator can move to the platform to assist the passengers in exiting. However, when the vehicle is located near the end of the platform, the operator can install a barrier at the end before allowing the passengers to exit the vehicle. Since the operator is working near the end of the platform, a safety line may be attached to the platform before installing the barrier. Unfortunately, the process of attaching the safety line and installing the barrier is very time - consuming, thus delaying the exit of passengers from the vehicle.

Summary of the Invention

Means for Solving the Problems

[0004] The following summarizes several embodiments within the same scope as the subject matter of the original claims. These embodiments are not intended to limit the scope of the claimed subject matter, but rather to outline possible forms of the claimed subject matter. In practice, the claimed subject matter may include a variety of forms that are similar to or different from the embodiments shown below.

[0005] In some embodiments, the movable fence assembly includes a first fence segment having at least one first bogie truck and a first barrier coupled to at least one first bogie truck. The at least one first bogie truck is configured to engage with a track located below the first barrier to facilitate the movement of the first fence segment along the track, and the first barrier is configured to prevent access across the first fence segment. The movable fence assembly further includes a second fence segment having at least one second bogie truck and a second barrier coupled to at least one second bogie truck. The at least one second bogie truck is configured to engage with the track to facilitate the movement of the second fence segment along the track, and the second barrier is configured to prevent access across the second fence segment. Furthermore, the movable fence assembly includes a connector that connects the first fence segment to the second fence segment. The connector is configured to cause movement of the second fence along the track in response to movement of the first fence along the track. Furthermore, the connector, the first and second fence segments, or a combination thereof, is configured to substantially maintain the distance between the first and second fence segments as the first and second fence segments move along the track.

[Modes for carrying out the invention]

[0008] The following describes one or more specific embodiments of this disclosure. For the sake of brevity, this specification may not describe all features of the embodiments. In developing any such embodiments, as can be seen in any engineering or design project, it should be understood that numerous implementation-specific decisions must be made to achieve the developer's specific objectives, such as compliance with system-related and business-related constraints, which may vary by implementation. Furthermore, while such development efforts can be complex and time-consuming, it should nevertheless be understood as routine design, fabrication, and manufacturing for an average engineer interested in this disclosure.

[0009] When describing elements of various embodiments of this disclosure, the articles “a,” “an,” “the,” and “said” mean that there are one or more of these elements. The terms “comprising,” “including,” and “having” are intended to be comprehensive and mean that there may be further elements other than those listed. The examples of operating parameters and / or environmental conditions do not preclude other parameters / conditions of the disclosed embodiments.

[0010] Figure 1 is a perspective view of an embodiment of a platform 10 and an embodiment of a movable fence assembly 12 configured to close the end 14 of the platform 10, with the movable fence 16 of the movable fence assembly 12 in the open position. In the illustrated embodiment, the platform 10 is part of an amusement park ride. The amusement park ride may include a vehicle suspended from a track, and the platform 10 may be located below the vehicle along a portion of the vehicle path through the ride. The platform 10 is configured to facilitate the exit of passengers from the vehicle in the event that the vehicle's movement suddenly ends while the vehicle is positioned above the platform. The movable fence 16 of the movable fence assembly 12 is also configured to move from the illustrated open position to the closed position before passengers exit the vehicle, preventing passengers from moving beyond the end 14 (e.g., the edge) of the platform 10.

[0011] While the movable fence 16 is in the open position as shown, vehicles can move through the vehicle by crossing the end 14 of the platform 10. If a vehicle unexpectedly stops near the end 14 of the platform 10, the operator 18 can prevent passengers from moving beyond the end 14 of the platform 10 by moving the movable fence 16 from the open position as shown. The operator can then allow passengers to exit the vehicle (for example, by releasing the passenger restraint system). As will be described in detail below, the operator 18 maintains a considerable distance from the end 14 of the platform 10 when moving the movable fence 16 along the curved track 20 of the movable fence assembly.

[0012] In the illustrated embodiment, the curved track 20 of the movable rail assembly 12 has a first portion 22 and a second portion 24. The first portion 22 of the curved track 20 is configured to be substantially parallel to the direction of movement 26 of the vehicle through the ride. The second portion 24 of the curved track 20 is configured to be substantially perpendicular to the direction of movement 26 of the vehicle through the ride. As used herein, “substantially parallel” means an orientation difference of less than 45 degrees, less than 30 degrees, less than 15 degrees, less than 10 degrees, less than 5 degrees, or less than 2 degrees. Furthermore, as used herein, “substantially perpendicular” means an orientation difference of 45 degrees or more, 60 degrees or more, 75 degrees or more, 80 degrees or more, 85 degrees or more, or 88 degrees or more. As shown in the illustration, the movable rail 16 is located on the first portion 22 of the curved track 20. Thus, the movable rail 16 is in an open position (e.g., a first position) that facilitates the movement of the vehicle through the ride. The movable barrier 16 is configured to move from an open position along the curved track 20 to a closed position (e.g., the second part) where it is located on a second part 24 of the curved track. While the movable barrier 16 is in the closed position, passenger movement beyond the end 14 of the platform 10 is prevented.

[0013] In the illustrated embodiment, the movable fence 16 includes a first fence segment 28, a second fence segment 30, a third fence segment 32, and a fourth fence segment 34. In the illustrated embodiment, the movable fence 16 includes four fence segments, but in other embodiments, the movable fence may include more or fewer (e.g., two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, or thirteen or more) fence segments. Furthermore, each fence segment includes one or more bogie trucks 36 and a barrier 38 coupled to the (single or double) bogie trucks. Each bogie truck 36 is configured to engage with the curved track 20 to facilitate the movement of each fence segment along the curved track 20. Additionally, each barrier 38 is positioned above the curved track 20 and is configured to prevent access across each fence segment (e.g., movement of people, movement of equipment, etc.) while the movable fence 16 is in the closed position. In the illustrated embodiment, each barrier 38 is formed by a plurality of rods joined to one another (e.g., by welded connections). However, in other embodiments, at least one barrier may be formed by any other preferred (single or double) structure configured to prevent access across each fence segment, such as (single or double) cables, (single or double) rods, (single or double) plates, (single or double) poles, other preferred (single or double) structures, or a combination thereof. Furthermore, in the illustrated embodiment, each fence segment includes two bogie trucks positioned at the opposing longitudinal ends of each fence segment. However, in other embodiments, at least one fence segment may include more or fewer (e.g., one, two, three, four, five, six, or seven or more) bogie trucks positioned at any preferred location along the fence segment.

[0014] In the illustrated embodiment, a first connector connects the first fence segment 28 to the second fence segment 30, a second connector connects the second fence segment 30 to the third fence segment 32, and a third connector connects the third fence segment 32 to the fourth fence segment 34. The first connector is configured to cause the second fence segment 30 to move along the curved track 20 in response to the movement of the first fence segment 28 along the curved track 20. Furthermore, the second connector is configured to cause the third fence segment 32 to move along the curved track 20 in response to the movement of the second fence segment 30 along the curved track 20. The third connector is configured to cause the fourth fence segment 34 to move along the curved track 20 in response to the movement of the third fence segment 32 along the curved track 20.

[0015] Since the fence segments are connected to each other by their respective connectors, the movable fence 16 can be moved from the open position to the closed position shown by applying force to the first fence segment 28 along the direction of vehicle movement 26 through the ride. For example, the operator 18 can drive the movable fence 16 along the track 20 by gripping / holding the first fence segment 28 and walking toward the end 14 of the platform 10. As shown, while the movable fence 16 is in the open position and the operator 18 is initially gripping / holding the first fence segment 28, the operator 18 is positioned beyond a threshold distance 40 from the end 14 of the platform 10. The threshold distance 40 can be selected based on applicable safety standards (selected, for example, by the ride manufacturer, ride operator, government agency, etc.). For example, the threshold distance can be 10 feet (e.g., 3 meters), 8 feet (e.g., 2.4 meters), 6 feet (e.g., 1.8 meters), 4 feet (1.2 meters), or any other preferred distance. As will be explained in detail below, compliance with applicable safety standards is facilitated by the operator maintaining a distance greater than a threshold distance from the unprotected end of the platform (e.g., the end of the platform not blocked by a movable fence) when walking toward the end 14 of the platform 10.

[0016] In some embodiments, the movable fence assembly 12 includes a pin that can penetrate an aperture in a bogie truck 36 (for example, a bogie truck positioned at the end of the movable fence 16 furthest from the end 14 of the platform 10 while the movable fence 16 is in the open position). The pin is configured to substantially reduce or eliminate the possibility of the movable fence 16 unintentionally moving away from the open position (e.g., towards the closed position) by selectively engaging with the aperture of the track 20 while the movable fence 16 is in the open position shown, thereby preventing the movable fence 16 from moving away from the open position. The pin is also configured to substantially reduce or eliminate the possibility of the movable fence 16 unintentionally moving away from the closed position (e.g., towards the open position) by selectively engaging with the aperture of the track 20 while the movable fence 16 is in the closed position, thereby preventing the movable fence 16 from moving away from the closed position. Furthermore, in some embodiments, the movable fence assembly 12 includes a sensor configured to allow an operator to determine the position of the movable fence while at a distance from the movable fence by outputting a signal indicating the position of the movable fence.

[0017] In the illustrated embodiment, the track 20 is curved and includes a first position 22 and a second section 24. However, in other embodiments, the track may have any other preferred shape (e.g., selectively closing the ends of the platform). For example, the track may be substantially straight (e.g., to allow the movable fence to move in one direction from an open position to a closed position). In a further example, the track may have three sections (e.g., separated by a curved section), and the movable fence may be configured to move between a first position in the first section of the track, a second position in the second section of the track, and a third position in the third section of the track. Furthermore, the track may be circular, elliptical, polygonal, or any other preferred shape or combination of shapes.

[0018] In the illustrated embodiment, the movable railing assembly 12 includes an anchor point 39 positioned close to the track 20. The anchor point 39 is configured to connect to a rope (e.g., a safety rope) extending from an operator 18. For example, the operator 18 may wear a harness, and a rope (e.g., a safety rope) may extend from the harness to the anchor point 39. In the illustrated embodiment, the movable railing assembly includes an anchor point, but in other embodiments, the anchor point may be omitted.

[0019] Figure 2 is a perspective view of the platform 10 and movable fence assembly 12 of Figure 1 with the movable fence 16 in a partially closed position. As shown, the operator 18 continues to grip the first fence segment 28 as the movable fence 16 moves from the open position to the closed position. When the movable fence 16 is in the partially closed position, the operator 18 is positioned closer to the end 14 of the platform 10 compared to the operator 18's position when the movable fence 16 is in the open position. However, the portion of the end 14 of the platform 10 closest to the operator 18 is blocked by the movable fence 16. Therefore, compliance with applicable safety standards is facilitated by the operator 18 maintaining a position beyond a threshold distance 40 from the unprotected end of the platform.

[0020] Figure 3 is a perspective view of the platform 10 and movable railing assembly 12 of Figure 1 with the movable railing 16 in the closed position. As shown, when the movable railing 16 is in the illustrated closed position, the movement of the operator 18 and passengers beyond the end 14 of the platform 10 is prevented by the movable railing 16. As described above, in some embodiments, a pin can pass through an aperture in a bogie truck 36 (for example, a bogie truck positioned at the end of the movable railing 16 furthest from the end 14 of the platform 10 while the movable railing 16 is in the open position). In such embodiments, the pin engages with an aperture in the track 20 while the movable railing 16 is in the illustrated closed position, preventing the movable railing 16 from moving away from the closed position, thereby substantially reducing or eliminating the possibility of the movable railing 16 unintentionally moving away from the closed position (for example, toward the open position).

[0021] The operator can grasp / hold the first gate segment 28 and walk towards the initial position as shown in FIG. 1 to move the movable gate 16 from the illustrated closed position to the open position. As described above with respect to the movement of the movable gate from the open position to the closed position, the operator can facilitate compliance with applicable safety standards by maintaining a state of being separated from the unprotected end of the platform by a distance exceeding the threshold value. Further, in embodiments including pins, the operator can release the pins from their respective apertures in the track before moving the movable gate from the closed position to the open position, and then engage the pins again in their respective apertures in the track in response to the movable gate reaching the open position to prevent the movement of the movable gate from the open position.

[0022] In the illustrated embodiment, the movable gate 16 is configured to be driven between the open position and the closed position by the operator 18, but in other embodiments, the movable gate can also be moved along the track via a drive device / system. For example, in some embodiments, a motor (e.g., an electric motor, a hydraulic motor, a pneumatic motor, etc.) can be configured to move the movable gate along the track. In some embodiments, a motor can be coupled to a winch system including a cable coupled to the movable gate. In such embodiments, the motor can move the movable gate along the track (e.g., from the open position to the closed position or from the closed position to the open position) by winding up the cable. A second motor and winch system can also be used to move the movable gate in the reverse direction. Further, in some embodiments, a motor can be coupled to the movable gate and configured to move the movable gate along the track by rotating one or more wheels of one or more bogie carriages. In other embodiments, other and / or additional (single / multiple) systems / (single / multiple) devices (e.g., selective coupling to a rotating platform, hydraulic cylinders, linear actuators, chain drives, etc.) can also be used to move the movable gate.

[0023] In the illustrated embodiment, the movable gate assembly 12 includes a fixed gate segment 41 that is disposed adjacent to the first gate segment 28 while the movable gate 16 is in the illustrated closed position. The fixed gate segment 41 is configured to block a portion of the end 14 that is not blocked by the movable gate 16. The spacing between the fixed gate segment 41 and the movable gate 16 can be selected to substantially prevent the movement of an operator 18 or a passenger past the movable / fixed gate segment. In the illustrated embodiment, the movable gate assembly includes a single fixed gate segment, but in other embodiments, the movable gate assembly can include more or fewer (e.g., 0, 1, 2, 3, 4, 5, 6, or 7 or more) fixed gate segments. For example, one fixed gate segment can be disposed at an end of the movable gate opposite the illustrated fixed gate segment (e.g., while the movable gate is in the closed position). In some embodiments, the fixed gate segment can include an extension configured to engage a notch within the barrier of an adjacent movable gate segment while the movable gate is in the closed position (e.g., such that the fixed gate segment and the barrier of the movable gate segment overlap along the direction of movement of the movable gate) to form an overlapping barrier arrangement. Further, in some embodiments, the fixed gate segment can include a notch configured to receive an extension of the barrier of an adjacent movable gate segment while the movable gate is in the closed position (e.g., such that the fixed gate segment and the barrier of the movable gate segment overlap along the direction of movement of the movable barrier) to form an overlapping barrier arrangement.

[0024] Figure 4 is a perspective view of the bogie truck 36 engaged with the track 20 of the movable rail assembly 12 in Figure 1. As shown, one first bogie truck 42 of the first rail segment 28 is coupled to one second bogie truck 44 of the second rail segment 30 by a connector 46. The connector 46 is configured to cause the movement of the second rail segment 30 along the track 20 in response to the movement of the first rail segment 28 along the track 20. For example, when the operator moves the first rail segment 28 from the open position to the closed position, the connector 46 drives the second rail segment 30 towards the closed position. Also, when the operator moves the first rail segment 28 from the closed position to the open position, the connector 46 drives the second rail segment 30 towards the open position. Similarly, the second connector connects the other second bogie of the second fence segment to the third bogie of the third fence segment, and the third connector connects the third bogie of the third fence segment to the fourth bogie of the fourth fence segment. The second connector is configured to cause the movement of the third fence segment along the track in response to the movement of the second fence segment along the track, and the third connector is configured to cause the movement of the fourth fence segment along the track in response to the movement of the third fence segment along the track. Thus, when the first fence segment moves along the track, the other fence segments also move along the track.

[0025] In the illustrated embodiment, the connector 46 includes a rod 48 pivotably coupled to a first bogie truck 42 and a second bogie truck 44. The rod 48 is substantially rigid. Thus, the rod 48 is configured to substantially maintain the spacing between the first and second rail segments as the movable rail 16 moves along the track by substantially maintaining the spacing between the first bogie truck 42 and the second bogie truck 44 as the movable rail 16 moves along the track 20. In the illustrated embodiment, the rod 48 is pivotably coupled to the first bogie truck 42 by a first coupling assembly 50 and pivotably coupled to the second bogie truck 44 by a second coupling assembly 52. ​​Each coupling assembly includes a mount 54, a bearing 56 and a fastener 58, and each mount 54 is coupled to the respective end of the rod 48. For example, threads may be formed on the outer surface of each end of the rod 48, and cavities in each mount 54 may have corresponding threads. The threads of the rod 48 can engage with the threads of the mount 54 via the rotation of the rod 48 and / or the mount 54, thereby coupling the mount 54 to the rod 48. Before the threads of the rod 48 engage with the threads of the mount 54, the nut 60 can be engaged with the threads of the rod 48. Thus, after the threads of the rod 48 have engaged with the threads of the mount 54, the possibility of the rod coming off the mount in response to its own rotation can be substantially reduced or eliminated by rotating the nut 60 to bring it into contact with the mount 54.

[0026] In the illustrated embodiment, each mount 54 has an aperture, and each bearing 56 is positioned within the aperture of the mount 54. Each bearing 56 also includes an aperture, and each fastener 58 passes through the aperture of the bearing 56. Furthermore, the body 62 of each bogie truck 36 includes an aperture, and each fastener 58 passes through the aperture of the body 62 of the bogie truck 36. The fasteners 58 are configured to connect each mount 54 to the body 62 of the bogie truck 36, and the bearings 56 are configured to facilitate the rotation of the rod 48 relative to each bogie truck 36 by facilitating the rotation of the mount 54 around the fastener 58. In some embodiments, each fastener 58 is a bolt having a head and a threaded end. The threaded end is configured to engage with a threaded nut to secure the fastener to the body and mount of the bogie truck. However, in other embodiments, the mount can also be pivotably connected to the bogie body using another suitable fastener such as a pin or rivet. Furthermore, in the illustrated embodiment, a bearing 56 is positioned between the fastener 58 and the mount 54, but in other embodiments, the bearing may be omitted and / or a bushing may be positioned between the fastener and the mount. Also, in the illustrated embodiment, the rod is connected to the bogie body using a mount, but in other embodiments, at least one end of the rod may include an aperture, through which the fastener / pin can pass to connect the rod to the respective bogie body.

[0027] In the illustrated embodiment, the connector includes a substantially rigid rod, but in other embodiments, at least one connector of the movable rail assembly may include another preferred device for moving another rail segment along the track in response to the movement of one rail segment along the track. For example, in some embodiments, a first bumper may be coupled to a first bogie truck of a first segment, and a second bumper may be coupled to a second bogie truck of a second segment. The first bumper can move the second rail segment toward the closed position by contacting the second bumper as the first rail segment moves from the open position toward the closed position. Alternatively, the connector may include a flexible connection, such as a cable or chain, between the first and second bogie trucks. This flexible connection can move the second rail segment toward the open position in response to the movement of the first rail segment from the closed position toward the open position. Furthermore, at least one connector may include other suitable connecting devices / assemblies, among many other suitable connectors, such as magnetic coupling assemblies between bogie trucks, or pivot couplings between protrusions securely coupled to the bogie truck bodies. The connectors, first and second fence segments, or combinations thereof, are configured to substantially maintain the spacing between the first and second fence segments as the movable fence moves along the track (e.g., substantially maintain the spacing between barriers while the movable fence is in the open, closed, and intermediate positions). As used herein, “substantially maintain” means that the maximum variation in the longitudinal range of the spacing of each fence segment (e.g., the range along the direction in which the movable fence moves) is less than a threshold percentage. The threshold percentage can be 20%, 15%, 10%, 5%, 2%, or 1%. The spacing between fence segments can be selected to facilitate rotation of one fence segment relative to an adjacent fence segment during the movement of the movable fence along the track and to establish a target spacing between barriers while the movable fence is in the closed position. The target spacing between barriers can be selected to prevent access across the movable fence (e.g., movement of people, movement of equipment, etc.).

[0028] In the illustrated embodiment, each bogie truck 36 has a plurality of wheels 64 configured to facilitate the movement of the bogie truck 36 along the track 20, and each wheel 64 is rotatably coupled to the body 62 of the bogie truck 36 (e.g., via its respective bearing). As shown, each wheel 64 has a contact surface 66 configured to engage with the upward surface 68 of the track 20. Thus, the wheels 64 are configured to transmit the vertical load (e.g., weight) of the movable rail 16 to the track 20, and the track 20 is configured to support the vertical load (e.g., weight) of the movable rail 16. Also, each wheel 64 is configured to rotate about its respective axis of rotation 70 which is substantially perpendicular to the direction of movement 72 of the movable rail 16. In the illustrated embodiment, each bogie truck 36 includes four wheels 64. However, in other embodiments, at least one bogie truck may include more or fewer (e.g., 0, 1, 2, 3, 5, 6, 7, 8 or 9 or more) wheels. For example, in some embodiments, at least one bogie truck may include a pad configured to contact the upward surface of the track to transmit the vertical load of the movable fence to the track and to facilitate the movement of the movable fence along the track.

[0029] In the illustrated embodiment, each bogie truck 36 includes end plates 74 positioned on both sides of the track 20. The end plates 74 are configured to prevent lateral movement of the bogie truck relative to the track 20 (e.g., movement of the bogie truck along a transverse axis 76). In the illustrated embodiment, each end plate 74 is coupled to the body 62 of the bogie truck 36 by fasteners 78. However, in other embodiments, at least one end plate can be coupled to the body of at least one bogie truck by any other preferred type of connector / connection assembly (e.g., welded connection, adhesive connection, etc.), and / or at least one end plate can be formed integrally with the body of at least one bogie truck. Furthermore, in the illustrated embodiment, a pad 80 is positioned between each end plate 74 and the side 82 of the track 20. Each pad 80 can be formed from a material that facilitates the movement of the bogie truck 36 along the track 20 while the pad 80 is in contact with the respective side 82 of the track. For example, at least one pad can be formed from ultra-high molecular weight (UHMW) polyethylene or any other suitable material. In the illustrated embodiment, a pad 80 is positioned between each end plate 74 and each side 82 of the track 20, but in other embodiments, at least one pad may be omitted. In such embodiments, the end plates can directly contact the side of the track to prevent lateral movement of the bogie truck relative to the track. Furthermore, in some embodiments, one or more wheels may be positioned on at least one side of at least one bogie truck, with each wheel having a contact surface configured to contact the side of the track. In such embodiments, each wheel rotates about a vertical axis, preventing lateral movement of the bogie truck relative to the track and facilitating movement of the bogie truck along the track.

[0030] In the illustrated embodiment, each end plate 74 has a lip 84 configured to contact the downward surface 86 of the track 20 to prevent upward movement of each bogie truck 36 along the vertical axis 88. Contact between the lip 84 and the downward surface 86 of the track can also prevent rotation of the movable rail 16 about the direction of movement 72. As a result, the movable rail 16 can support large lateral forces (e.g., forces along the lateral axis 76), such as when a person leans against the rail. For example, each rail segment can be configured to support lateral forces (e.g., forces along the lateral axis) greater than a threshold lateral force applied to the top of the rail segment. The threshold lateral force can be selected based on applicable safety standards (e.g., selected by the vehicle manufacturer, vehicle operator, government agency, etc.). For example, the threshold lateral force can be 50 pounds (e.g., 22.7 kgf), 100 pounds (e.g., 45.4 kgf), 150 pounds (e.g., 68.0 kgf), 200 pounds (e.g., 90.7 kgf), 250 pounds (e.g., 113.4 kgf), 300 pounds (e.g., 136.1 kgf), or any other preferred lateral force. In the illustrated embodiment, a lip 84 on the end plate 74 is used to prevent the upward movement of the bogie truck 36 and the rotation of the movable rail 16, but in other embodiments, at least one bogie truck may include another or additional device / assembly configured to prevent the upward movement / rotation of the movable rail of the (single or double) bogie truck. For example, in some embodiments, at least one bogie truck may include at least one wheel positioned below the track and configured to rotate about a pivot axis substantially parallel to the lateral axis 76. In such embodiments, the contact surfaces of each wheel can be configured to contact the downward surface of the track to prevent the upward movement of the (single or double) bogie truck / rotation of the movable fence, thereby facilitating the movement of the movable fence along the track.

[0031] As will be described in detail below, the rods of each barrier 38 facilitate the rotation of the bogie trucks 36 relative to the barrier 38 by pivotally connecting to their respective bogie trucks 36. For example, bushings can be placed around the rods to facilitate the rotation of the bogie trucks relative to the barrier. The pivoting of each bogie truck allows the movable fence to follow a curved track. Furthermore, in the illustrated embodiment, the movable fence assembly 12 includes a single type of bogie truck 36. Thus, the bogie trucks 36 of the movable fence assembly 12 are substantially the same as one another. For example, the first bogie truck 42 of the first fence segment 28 and the second bogie truck 44 of the second fence segment 30 are positioned to connect their respective apertures to the connector 46 by facing in opposite directions along the direction of movement 72. Since a single type of bogie truck is used within the movable fence assembly, the cost and complexity of the movable fence assembly can be reduced compared to a movable fence assembly that includes multiple types of bogie trucks. However, in other embodiments, the movable fence assembly may also include multiple types of bogie trucks.

[0032] In some embodiments, the track and bogie truck can be positioned below the platform. In such embodiments, a rod of a barrier pivotally coupled to the bogie truck can pass through a slot in the platform. Thus, the platform can facilitate the movement of the movable fence by preventing at least some of the dirt and / or debris from becoming involved with the track. In some embodiments, a deformable cover (e.g., flexible fingers, bristles, etc.) can be placed in the slot to facilitate the movement of the movable fence along the track while further preventing dirt and / or debris from becoming involved with the track.

[0033] Figure 5 is an exploded view of one of the bogie trucks 36 in Figure 4 (for example, one of the first bogie trucks on the first rail segment, one of the second bogie trucks on the second rail segment, etc.). In the illustrated embodiment, the body 62 of the bogie truck 36 includes an aperture 90 configured to receive a fastener or pin. For example, as described above, a fastener can pivotally connect a mount to the body 62 of the bogie truck 36 by passing through the aperture 90 of the bogie truck body 62 and the aperture of a bearing located within the aperture of the mount. Furthermore, as will be described in detail below, a pin can pass through the aperture 90 of the bogie truck body 62. This pin is configured to selectively engage with the aperture of the track while the movable rail is in the open position to prevent the movable rail from moving from the open position. The pin is also configured to selectively engage with the aperture of the track while the movable rail is in the closed position to prevent the movable rail from moving from the closed position.

[0034] Furthermore, in the illustrated embodiment, each wheel 64 is rotatably coupled to the body 62 of the bogie truck 36 by its respective bearing 92. The bearing 92 is configured to reduce the force required to move the movable rail between the open and closed positions by facilitating the rotation of the wheel 64. In the illustrated embodiment, each wheel is rotatably coupled to the body of the bogie truck by its respective bearing, but in other embodiments, at least one bearing may be omitted, and / or at least one wheel may be rotatably coupled to the body of the bogie truck by other suitable devices / assemblies (e.g., bushings).

[0035] As described above, the rod 94 of the barrier is pivotally coupled to the bogie truck 36 to facilitate rotation of the bogie truck 36 relative to the barrier about a vertical axis 88. In the illustrated embodiment, the rod 94 is configured to be non-rotatably coupled to another component of the barrier (e.g., another rod) via a fastener 96. In the illustrated embodiment, the fastener includes a bolt configured to non-rotatably couple the rod to the other component by passing through the aperture of the rod and the aperture of the other component of the barrier. However, in other embodiments, the fastener may include any other suitable device / assembly (e.g., a cotter pin, a rivet, etc.) configured to couple the rod to the other barrier component. Furthermore, in some embodiments, the rod may also be coupled to the other component of the barrier by another suitable connection (e.g., a welded connection, an adhesive connection, etc.), or the rod may be formed integrally with the other component of the barrier.

[0036] In the illustrated embodiment, the rod 94 is pivotably coupled to the body 62 of the bogie truck 36 via a first bushing 98 and a second bushing 100. In the illustrated embodiment, the rod is pivotally coupled to the body of the bogie truck via two bushings, but in other embodiments, the rod may also be coupled to the body of the bogie truck via more or fewer (e.g., 0, 1, 3, 4, 5, 6, or 7 or more) bushings and / or other suitable components (e.g., bearings). In the illustrated embodiment, the first bushing 98 has a lip 102, the second bushing 100 has a lip 104, and the rod 94 has a lip 106. The lip of each bushing is configured to prevent the bushing from moving toward the body of the bogie truck along the vertical axis 88 (e.g., via contact with the body 62 of the bogie truck 36). Furthermore, the lip 106 of the rod 94 is configured to prevent the movement of the rod 94 toward the bogie truck body 62 along the vertical axis 88 (for example, through contact with the lip 102 of the first bushing 98). Thus, the weight of the barrier is transmitted to the bogie truck via the lip of the rod and the lip of the first bushing. In addition, a fastener 108 (for example, a cotter pin, bolt, etc.) is configured to penetrate the aperture of the rod 94 and prevent the movement of the rod 94 away from the bogie truck body 62 along the vertical axis 88. In the illustrated embodiment, the lip 104 of the second bushing 100 is configured to prevent the movement of the rod 94 away from the bogie truck body 62 along the vertical axis 88 by preventing the upward movement of the fastener 108.

[0037] In some embodiments, a washer can be placed between the lip of the second bushing and the fastener 108 to facilitate the rotation of the rod relative to the body of the bogie truck. Furthermore, in some embodiments, at least one bushing can be non-rotatably coupled to the body of the bogie truck (e.g., by fasteners (single or double), adhesive connections, welded connections, etc.). In some embodiments, the lip of at least one bushing can be omitted, and / or the lip of the rod can be omitted. For example, in some embodiments, the lip of the rod can be omitted and replaced with a fastener configured to contact the first bushing. In such embodiments, the rod may include another lip configured to be located below the body of the bogie truck, in which case the second bushing is configured to prevent the rod from moving away from the body of the bogie truck along the vertical axis by preventing the upward movement of the other lip. Furthermore, in some embodiments, the rod can also be coupled to the body of the bogie truck non-translatably and pivotably by another preferred coupling assembly.

[0038] Figure 6 is a perspective view of a bogie truck 36 and track 20, where the movement of the bogie truck 36 along the track 20 is prevented by a pin 110 engaged with the bogie truck 36 and the track 20. As shown, the movable fence 16 is in a closed position, preventing passengers from moving beyond the end of the platform 10. When the movable fence 16 is in the closed position, the aperture 90 of the body 62 of the bogie truck 112 of the first fence segment 28 aligns with the corresponding aperture 114 (e.g., a second aperture) of the track 20. Thus, the pin 110 can be positioned through the aperture 90 of the body 62 of the bogie truck 112 of the first fence segment 28 and the aperture 114 of the track 20 to prevent the movable fence 16 from moving from the closed position. Furthermore, in some embodiments, another aperture (e.g., a first aperture) can be formed within the track. While the movable fence is in the open position, the aperture of the bogie truck body of the first fence segment can be aligned with other apertures in the track. A pin or another pin can be positioned through the aperture of the bogie truck body of the first fence segment and other apertures in the track to prevent the movable fence from moving from the open position. In some embodiments, the head of the pin is colored (e.g., red, yellow, etc.) to facilitate visual identification of the pin's position (e.g., whether the pin is engaged with the aperture). For example, the colored pin head can be seen when the pin is not engaged with the aperture and can be hidden by the bogie truck body when the pin is engaged with the aperture. Furthermore, in some embodiments, the pin can be movably coupled to the bogie truck body to prevent the pin from being removed from the aperture of the bogie truck body. In other embodiments, the pin can be detachable from the bogie truck body.

[0039] In the illustrated embodiment, the pin 110 is configured to pass through the aperture 90 of the body 62 of the bogie truck 112 of the first fence segment 28, but in other embodiments, the pin may be configured to pass through another preferred opening. For example, in some embodiments, the bogie truck of the first fence segment may have another preferred aperture / opening configured to receive the pin while the pin is engaged with an aperture in the track. Furthermore, in some embodiments, another preferred bogie truck or another preferred element of the movable fence may include an aperture / opening configured to receive the pin while the pin is engaged with an aperture in the track. In some embodiments, the pin may pass through a first aperture / opening of the movable fence while engaged with one aperture in the track, and pass through a second aperture / opening of the movable fence, different from the first aperture / opening, while engaged with another aperture in the track. Furthermore, in some embodiments, the movable rail assembly may include a first pin configured to engage with one aperture in the track and a second pin configured to engage with another aperture in the track, with each pin engaging with a suitable aperture / opening of the movable rail while engaging with the respective aperture in the track. Although two track apertures have been disclosed above, in some embodiments, the track may include any number of suitable apertures to prevent the movement of the movable rail at multiple positions.

[0040] In the illustrated embodiment, the pin is configured to manually engage with the (single or double) apertures of the track while the movable fence is in the open and / or closed positions, thereby preventing the movement of the movable fence. However, in other embodiments, the pin can also be biased to engage with the apertures of the track by a biasing element such as a spring or elastic piece extending from the bogie body to the pin. In such embodiments, the pin can automatically engage with the apertures in response to aligning with each aperture in the track. In some embodiments, ramps can extend along the track toward each aperture to guide the pin to each aperture. Furthermore, in some embodiments, the pin can also be biased away from the (single or double) track apertures by a biasing element such as a spring or elastic piece extending from the bogie body to the pin. In such embodiments, as the pin approaches / reaches each aperture, a drive element coupled to the track (e.g., ramp) can contact the pin and engage it with the respective aperture.

[0041] Furthermore, in some embodiments, the movable rail assembly may include an actuator configured to selectively engage a pin with at least one aperture in the track. For example, a linear actuator, a pneumatic actuator (e.g., a pneumatic cylinder), a hydraulic actuator (e.g., a hydraulic cylinder), a solenoid, or any other suitable actuator may be coupled to the bogie body and configured to selectively drive the pin to at least one aperture in the track. In some embodiments, the actuator can be controlled manually by an operator (e.g., via a switch or button). Furthermore, in some embodiments, a controller communicatively coupled to the actuator can control the actuator. The controller may be configured to command the actuator to engage the pin with the track aperture in response to receiving a signal indicating that the movable rail is in a target position (e.g., open or closed).

[0042] In the illustrated embodiment, the movable fence assembly 12 includes at least one sensor 116 configured to output a signal indicating the position of the movable fence 16. In some embodiments, the (single or double) sensor 116 may output a first signal indicating that the movable fence 16 is in the open position, and / or a second signal indicating that the movable fence 16 is in the closed position. Furthermore, in some embodiments, the (single or double) sensor 116 may output (single or double) signals indicating the position of the movable fence 16 along the track 20. The (single or double) sensor may include any preferred (single or double) device configured to monitor the position of the movable fence. For example, each sensor may include a contact switch, a magnetic switch, an inductive sensor, a capacitive sensor, an infrared sensor, an optical sensor (e.g., a camera), another preferred sensing device, or a combination thereof. In some embodiments, the movable fence assembly may include a first sensor (e.g., a first contact switch, etc.) and a second sensor (e.g., a second contact switch, etc.). The first sensor may be configured to output a signal indicating the presence of the movable fence in the open position (for example, in response to contact between the movable fence and the first contact switch), and the second sensor may be configured to output a signal indicating the presence of the movable fence in the closed position (for example, in response to contact between the movable fence and the second contact switch). Furthermore, in some embodiments, the movable fence assembly may include a plurality of sensors (e.g., induction sensors) positioned along the movable fence and configured to output signals at each (one or multiple) sensor indicating the presence of the movable fence.

[0043] In some embodiments, (one or multiple) sensors 116 are communicatively coupled to a user interface (e.g., via a controller), and the user interface is configured to allow an operator to determine the position of the movable fence (e.g., while positioned away from the movable fence) by indicating the position of the movable fence (e.g., via a screen, speaker, or one or more discrete lights, etc.). Furthermore, in some embodiments, as disclosed above, (one or multiple) sensors can be communicatively coupled to a controller (e.g., having memory and a processor) which can be communicatively coupled to an actuator. The controller can receive (one or multiple) signals from the sensors indicating the position of the movable fence (e.g., that the movable fence is in an open or closed position). In some embodiments (e.g., the controller is communicatively coupled to the actuator), the controller can command the actuator to engage a pin in each aperture in the track in response to receiving a signal indicating that the movable fence is in a closed position, and / or command the actuator to engage a pin in each aperture in the track in response to receiving a signal indicating that the movable fence is in an open position. Furthermore, in some embodiments, the controller may terminate the vehicle's operation and / or output a signal (e.g., to the vehicle controller) indicating the termination of the vehicle in response to feedback from (one or more) sensors indicating that the movable fence is not in the open position.

[0044] In some embodiments, the movable rail assembly may include one or more sensors configured to output (one or more) signals indicating the position of a pin relative to each aperture in the track. For example, a (one or more) sensor may output a first signal indicating that the pin is engaged with a first aperture in the track, and / or a second signal indicating that the pin is engaged with a second aperture in the track. The (one or more) sensor may include any preferred (one or more) device configured to monitor the position of the pin. For example, each sensor may include a contact switch, a magnetic switch, an inductive sensor, a capacitive sensor, an infrared sensor, an optical sensor (e.g., a camera), a linear variable differential transformer, another preferred sensing device, or a combination thereof. A user interface communicatively coupled to the (one or more) sensors (e.g., via a controller) may inform the operator whether the pin is engaged with either the first or second aperture in the track by indicating the position of the pin.

[0045] To facilitate the movement of the movable fence 16 from the closed position to the open position, or from the open position to the closed position, the pins can be released from each aperture in the track 20. For example, in the illustrated embodiment, the operator can manually release the pins from each aperture before moving the movable fence to the opposite position. Furthermore, in some embodiments, the actuator can release the pins from each aperture in the track (for example, in response to a control signal from a controller).

[0046] In some embodiments, one or more of the track apertures disclosed above can be omitted from the track. In such embodiments, the railing assembly may include one or more other suitable devices / assemblies configured to prevent the railing from moving while it is in the open and / or closed position. Furthermore, the railing assembly may include one or more other suitable devices / assemblies configured to prevent the railing from moving while it is in the open and / or closed position, in addition to the pin / track aperture system. In some embodiments, the railing assembly may include one or more latches (e.g., (single and double) trap keys) configured to prevent the railing from moving while it is in the open and / or closed position. Each latch may automatically engage in response to the railing reaching its respective position. Furthermore, in some embodiments, the railing assembly may include (single and double) cables and / or (single and double) chains configured to selectively couple the railing to the fixed railing segment of the railing assembly to prevent the railing from moving while it is in the open and / or closed position. In some embodiments, the railing assembly may include one or more retractable pins configured to selectively extend from the track. In such embodiments, each actuator may drive each pin between a retracted position and an extended position, and the controller may command each actuator to extend each pin in response to the pin aligning with the respective aperture / opening of the railing (e.g., while the railing is in an open or closed position). In some embodiments, one or more devices / assemblies configured to prevent the movement of the railing may be unlocked with a key only (e.g., to allow the movement of the railing). Furthermore, in some embodiments, one or more devices / assemblies configured to prevent the movement of the railing may also be unlocked without the use of a key.

[0047] Figure 7 is a perspective view showing an embodiment of a rotating platform 118 and an embodiment of a movable railing assembly 119 configured to selectively extend along the periphery 120 of the rotating platform 118. The movable railing assembly 119 may include the same components as the movable railing assembly 12 disclosed above with reference to Figures 1 to 6 (e.g., tracks, multiple railing segments, (single and multiple) connectors between railing segments, etc.), and may also include any of the modifications disclosed above with reference to the movable railing assembly 12 in Figures 1 to 6. In the illustrated embodiment, the rotating platform 118 is configured to rotate in direction 122. In some embodiments, passengers can enter the rotating platform 118 (e.g., via a bridge) to access vehicles coupled to the rotating platform 118. Tracks extend to the rotating platform 118, around the rotating platform 118, and away from the rotating platform 118, and vehicles can travel along the tracks. Each vehicle travels along the track toward the rotating platform and can be coupled to the rotating platform upon reaching it. The rotation of the rotating platform allows (one or more) passengers standing on the rotating platform to board the vehicle by driving the vehicle along a section of track that extends around the rotating platform. The vehicle then departs from the rotating platform when it reaches the section of track that extends away from the rotating platform.

[0048] When the vehicle is not in operation, the movable fence 16 can be used to block off the perimeter 120 of the turning platform 118, preventing (one or more) passengers and (one or more) operators from moving beyond the perimeter of the turning platform. When the vehicle is in operation, the movable fence 16 can be stored in a storage area. The storage area may include a movable fence track, to which one or more bogie trucks of each fence segment can be engaged to facilitate the movement of each fence segment along the track. The movable fence track may also extend around the turning platform (for example, radially inward from the vehicle track). The movable fence is coupled to the turning platform in response to the end of the vehicle operation, and the rotation of the turning platform can drive the movable fence from an open position in the storage area to the illustrated closed position where the movable fence extends along the perimeter of the turning platform. To move the movable fence from the illustrated closed position to an open position where the movable fence is located in the storage area, the last fence segment of the movable fence can be moved from the portion of the movable fence track extending around the turning platform to the portion of the movable fence track in the storage area. Subsequently, the rotating platform can rotate in the opposite direction (for example, with respect to rotation direction 122). As a result, the rotation of the rotating platform can move the movable railing from the closed position to the open position shown in the figure.

[0049] In the illustrated embodiment, the first railing segment 28 includes a first engagement feature 124 configured to selectively engage with a second engagement feature 126 of the rotating platform 118. Rotation of the rotating platform 118 (e.g., in the rotational direction 122) can extend the movable railing 16 along the periphery 120 of the rotating platform 118 in response to the engagement of the first and second engagement features. For example, the rotation of the rotating platform can be stopped in response to the end of a vehicle operation. The second engagement feature 126 of the rotating platform 118 can be aligned with the first engagement feature 124 of the first railing segment 28 (e.g., by rotating the rotating platform 118). The engagement of the first and second engagement features with each other can couple the movable railing 16 to the rotating platform 118. Subsequently, rotation of the rotating platform 118 can move the movable railing 16 from an open position where the movable railing 16 is positioned within the storage area to the illustrated closed position where the movable railing 16 extends along the periphery 120 of the rotating platform 118. Subsequently, the rotation of the rotating platform can be stopped. In some embodiments, in order to move the movable fence 16 from the illustrated closed position to the open position, the last fence segment of the movable fence can be moved from the portion of the movable fence track extending around the rotating platform to the portion of the movable fence track within the storage area. The rotating platform 118 can then be rotated in the reverse direction. As a result, the rotation of the rotating platform can move the movable fence 16 from the closed position to the open position. When most of the movable fence is within the storage area, the rotation of the rotating platform can be stopped, the first and second engagement features can be released, and the remaining portion of the movable fence can be moved into the storage area.

[0050] The first and second engagement features can be any preferred device configured to selectively couple the movable railing to the rotating platform. For example, in some embodiments, the first or second engagement feature may include a latch, and the other engagement feature may include a pin (e.g., a rod of the barrier of the first segment) configured to engage with the latch. Furthermore, in some embodiments, the first and second engagement features may include one or more magnets, one or more pins, one or more receptacles, one or more latches, one or more cables, one or more chains, one or more other preferred connecting devices / assemblies, or a combination thereof. In some embodiments, the first and second engagement features can automatically couple with each other in response to contact between them. Furthermore, in some embodiments, the first and second engagement features can be manually engaged.

[0051] In the illustrated configuration, the movable rail extends along the entire perimeter of the rotating platform while in the closed position; however, in other embodiments, the movable rail may extend along only a portion of the perimeter of the rotating platform while in the closed position. Also, in the illustrated configuration, the rotating platform is circular; however, in other embodiments, the rotating platform may have any other preferred shape, such as elliptical or polygonal. Furthermore, in the illustrated configuration, the rotation of the rotating platform is configured to drive the movable rail between the open and closed positions; however, in other embodiments, the movable rail may be manually moved from the open position to the closed position and / or from the closed position to the open position. In some embodiments, the movable rail may be moved from the open position to the closed position and / or from the closed position to the open position by a drive / system separate from the rotating platform, such as one or more of the drive / systems disclosed above with reference to Figures 1 to 3.

[0052] In some embodiments, at least one railing segment may include a foldable barrier configured to reduce the length of the movable rail while the movable rail is in an open (e.g., storage) position. For example, in some embodiments, at least one railing segment may include a barrier and two bogies pivotably coupled to the barrier. The barrier may include at least one hinge positioned between the two bogies. The hinge (single or double) allows the two bogies to move toward each other by folding the barrier. Thus, with the barrier in the folded position, the length of the movable rail is reduced, thereby shortening the length of the track sufficient to support the movable rail while the movable rail is in an open / storage position. In some embodiments, the railing segment may include a biasing element configured to facilitate the transition of the movable rail from an unfolded configuration (e.g., while the movable rail is in a closed position) to a folded configuration (e.g., while the movable rail is in an open position) by biasing the barrier toward a folded position. The biasing element may include any preferred (single or double) device configured to bias the barrier to the folded position (e.g., a (single or double) spring, an (single or double) elastic element, a (single or double) pneumatic cylinder, a (single or double) hydraulic cylinder, etc.). Furthermore, in some embodiments, the fence segment may include a locking mechanism configured to fix the barrier in the extended position (e.g., while the movable fence is in the closed position). The locking mechanism may include any preferred (single or double) device configured to fix the barrier in the extended position (e.g., one or more latches, one or more pins, one or more clips, etc.).

[0053] As an example, while the movable fence is in the open position, the length of the movable fence can be shortened by folding one or more fence segments (one or more) of the barrier. By moving the first fence segment toward the closed position, the remaining portion of the movable fence can be driven toward the closed position. When the movable fence moves from the open position to the closed position, an operator or automated system can move each barrier in the folded position to the unfolded position. For example, when the movable fence moves from the open position to the closed position, an operator can manually unfold each folded barrier and then engage its respective locking mechanism to fix the barrier in the unfolded position. In some embodiments, in response to contact with structures (e.g., inclines) of the movable fence assembly when the movable fence moves from the open position to the closed position, these structures (one or more) can be driven to the unfolded position. Furthermore, in some embodiments, the locking mechanism can be automatically engaged in response to the unfolding of the barriers.

[0054] Furthermore, the movable fence can be moved towards the closed position by moving the first fence segment toward the closed position in order to move the movable fence from the closed position to the open position. The operator or automated system can release each locking mechanism (for example, when the movable fence has passed the operator / automated system or after the movable fence has moved to the closed position). Once the locking mechanisms are released, each (single or multiple) biasing element can drive each barrier to the folded position. In some embodiments, each (single or multiple) feature of the movable fence assembly (e.g., (single or multiple) projections, (single or multiple) rods, etc.) contacts the respective locking mechanism as each folding barrier passes over it, thereby driving the locking mechanism to the released position.

[0055] In some embodiments, the biasing element of at least one folding barrier can be omitted (for example, the folding barrier can be manually moved to the folded position). Furthermore, in some embodiments, at least one folding barrier may include an actuator configured to drive the folding barrier from the folded position to the unfolded position and / or from the unfolded position to the folded position. The actuator may include any preferred (one or more) device configured to control the position of the barrier, such as a linear actuator, a hydraulic cylinder, a pneumatic cylinder, another preferred device, or a combination thereof. In embodiments in which the folding barrier includes an actuator, the biasing element and / or locking mechanism can be omitted.
