Description:
RELATED APPLICATIONS  
       [0001]    This application claims the benefit of U.S. Provisional Application No. 60/403,375, filed Aug. 14, 2002, entitled U-FLY AMUSEMENT AIR POOL AND RIDING DEVICE, the entirety of which is hereby incorporated by reference herein. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    1. Field of the Invention  
           [0003]    The invention relates to the field of recreational, entertainment or amusement sports. More particularly, the invention relates to an air pool or arena and riding devices therefor that enable multiple participants and/or passengers to fly freely in the riding devices within the air pool and experience unprecedented flying amusement.  
           [0004]    2. Description of the Related Art  
           [0005]    Most conventional skydiving simulators or wind tunnels are not targeted for the general public. Undesirably, the ones that are used for amusement purposes typically require some degree of training and may not be suitable for many individuals. Moreover these are generally limited to a single individual flight and at most permit only about two people to fly in the tunnel at the same time.  
           [0006]    One risk in allowing multiple users to skydive at the same time is that individuals may collide with one another. Hence, disadvantageously, with multiple skydiving participants, individual riders may disrupt others and lose control themselves or cause others to lose control within the tunnel. This can compromise the safety of the participants.  
           [0007]    Most conventional riding devices used in amusement, entertainment or recreational parks, such as roller coaster carts and the like, provide predefined movement and acceleration. This is controlled by the system requirements and the operator controlling the system and undesirably does not allow participants to control their ride. Moreover, these riding devices are in some form or the other mechanically connected to a base or ground surface, for example, by a track or cable. Disadvantageously, this does not permit the participants to ride “freely” in the devices.  
         SUMMARY OF THE INVENTION  
         [0008]    The invention relates to the field of recreational, entertainment or amusement sports. More particularly, the invention relates to an air pool or arena and riding devices therefor that enable multiple participants and/or passengers to fly freely in the riding devices within the air pool and experience unprecedented flying amusement.  
           [0009]    Advantageously, the air pool and riding devices therefor of embodiments of the invention may be efficaciously utilized by most individuals of the general public without any type of training or special gear or dress as is necessitated by conventional skydiving simulators. In addition, a large capacity or crowd of individuals may ride at the same time or simultaneously within the air pool. Since the individual ride participants are well protected inside the riding devices, they can safely indulge in collisions or bumping between the devices and this adds to the amusement experience for the riders and utility of the overall system.  
           [0010]    The air pool and riding devices of embodiments of the invention not only provide for free-flying and bumping experiences but desirably also provide motion control, by allowing three-dimensional acceleration of the device, through the individual riders own control. The unique “freely” flying riding devices provide a novel addition to any existing amusement, entertainment or recreational parks. This offers a desirable and valuable enhancement to existing parks by providing an unprecedented amusement and entertainment experience for the attendees. In some embodiments, the amusement system is portable and comprises a modular structure which allows it to be easily installed at and moved between various sites. In some embodiments, the amusement system is integrated with or comprises a computer system and an audio/video and data communication system to simulate virtual reality experiences.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0053]    [0053]FIG. 1 is a simplified view of an amusement air pool system or arena  10 . A plurality of riding flight devices or crafts  210  are shown being piloted by passengers and flying “freely” in the arena  10 .  
         [0054]    In the illustrated embodiment of FIG. 1, the amusement air pool system  10  generally comprises a main chamber or tunnel  12  including a free flying arena  14  and a top safety zone  16  at its downstream end and a bottom safety zone  18  at its upstream end. The amusement air pool system  10  further comprises an air feeding unit or system  20 , an air control unit or system  22  and an air feeding unit or system  24 . Though air is the preferred medium or suitable gases or combinations thereof may be efficaciously utilized, as needed or desired.  
         [0055]    FIGS.  2 - 4  show different views of the free flying arena, chamber or tunnel  14  of the amusement air pool system  10 . The arena  14  has an upstream end  26  and a downstream  28 .  
         [0056]    In the illustrated embodiment of FIGS.  2 - 4 , the arena  14  has a passage  25  with a generally circular inner cross-section (see, for example, FIGS. 3 and 4) with the smallest diameter at about the upstream or inlet end  26  and the largest diameter at about the outlet end  28 . The arena diameter is about constant near the upstream end  26  and gradually flares or increases in the direction of the downstream end  28 .  
         [0057]    In the illustrated embodiment of FIGS.  2 - 4 , the arena  14  has a substantially round inner cross-section to reduce possible secondary flows which might be created around any corners. In other embodiments, other suitable shapes substantially without sharp corners, for example, oval, ellipsoidal and the like, may also be efficaciously utilized, as needed or desired. In modified embodiments, further suitable shapes may be efficaciously utilized, as needed or desired. For example, polygonal inner cross-sections such as hexagonal, and the like.  
         [0058]    Referring in particular to FIG. 2, as the skilled artisan will appreciate that for a given input flow rate Q through the passage  25 , the local velocity V is generally given by the expression:  
       V   =     Q   A                           
 
         [0059]    where, A is the inner cross-sectional area. Thus, the highest local velocity V max  in the passage  25  will be at or near the inlet end  26  and decrease along the passage  25  in the direction generally indicated by arrow  30  in FIG. 2 to the lowest local velocity V min  at or near the outlet end  28 .  
         [0060]    Still referring in particular to FIG. 2, the tunnel arena  14  or the passage  25  can be divided into a plurality of zones or regions. In FIG. 2, four playing zones or areas Z 1 , Z 2 , Z 3  and Z 4  are illustrated though fewer or more zones may efficaciously be designated, as needed or desired. For a given input flow rate Q, the average velocity or velocity range in each of the zones Z 1 , Z 2 , Z 3  and Z 4  is designated as V 1 , V 2 , V 3  and V 4  respectively, where: 
         V 1 &gt;V 2 &gt;V 3 &gt;V 4   
         [0061]    Assuming V 4  is set so that an object with a mass m 4  (density ρ 4 )is suspended or floats within the zone Z 4 . (For simplicity, these objects are assumed to be spherical and have the same dimensions.) Then, objects having successively greater mass m 3 , m 2  and m 1 , that is, successively greater density ρ 3 , ρ 2  and ρ 1 , will be suspended in zones Z 3 , Z 2  and Z 1  respectively, where: 
         m 1 &gt;m 2 &gt;m 3 &gt;m 4   
         ρ 1 &gt;ρ 2 &gt;ρ 3 &gt;ρ 4   
         [0062]    Thus, by selection of the velocities and the configuration of the channel, a plurality of objects may be levitatingly dispersed or suspended at different positions or heights within the arena  14 . As discussed further below, the objects, or in this case the riding devices  210  (see, for example, FIG. 1), are also specially configured and equipped so that the devices  210  may be controlled by the rider to move within the arena  14 .  
         [0063]    The basic fluid mechanics involved in suspending objects in a flow can be conceptualized in different ways. In one aspect, the objects can be said to be fluidized within the channel, that is, the upward drag force on each object is balanced by its downward weight. In another aspect, the local fluidization velocity can be thought of as the terminal velocity of the object, that is, the weight is balanced by the buoyant force.  
         [0064]    Optionally, a zone isolation unit (not shown) can be provided between one or more pairs of adjacent playing zones, for example, between zones Z 1  and Z 2 . The isolation unit prevents any riding units  210  from moving across from one playing zone into the other playing area. It may also serve as a loading/unloading section for the playing area located above the isolation unit. The isolation zone is typically configured in the shape of the adjacent arena inner cross-section and comprises a suitable net-like sheet or device which allows the flow of air therethrough and is sufficiently strong to safely support the riders and the riding devices. The isolation unit is an optional device, for embodiments in which separation between the playing zones is desired.  
         [0065]    The free flying arena  14  (FIGS.  1 - 4 ) can be fabricated from a wide variety of suitably durable materials. In one embodiment, the arena  14  comprises a substantially transparent material such as a composite plastic or thermoplastic so that spectators may view the riding devices  210  within the air pool or passage  25  and vice versa. Substantially the entirety of the arena  14  may be transparent or selected sections only may be transparent, for example, in the form of see-through windows or panels. In modified embodiments, the arena  114  may efficaciously be fabricated from other plastics, metals, alloys, ceramics, combinations thereof, and the like, as needed or desired.  
         [0066]    In some embodiments, the arena  14  (FIGS.  1 - 4 ) and the other associated components of the amusement system  10  and the riding crafts  210  comprise a modular structure. That is, the various portions can be easily assembled and disassembled which desirably allows the system  10  and the riding crafts  210  to be portable or easily transportable and installable at various sites, as needed or desired. Advantageously, this permits the system  10  and the riding crafts  210  to be moved between amusement parks, fairs and the like. Also, it allows for an easy installation and set-up for a permanent construction, if desired or needed.  
         [0067]    The arena  14  (FIGS.  1 - 4 ) can be configured and dimensioned in a number of suitable manners. The arena  14  is preferably configured and dimensioned in accordance with the number of riding crafts  210  that it can comfortably accommodate.  
         [0068]    In one embodiment the arena upstream end  26  (see, for example, FIGS. 1, 2 and  4 ) is dimensioned to provide about 3.7 m 2  (40 square feet or ft 2 ) for each riding unit  210 . Of course, a larger or smaller area per riding unit may also be utilized, as needed or desired.  
         [0069]    Thus, in general, for ten riding units  210 , the arena upstream end  26  has an inner cross-sectional area of about 37 m 2  (400 ft 2 ) and an inner diameter of about 7 m (23 ft). For one hundred riding units  210 , the arena upstream end  26  has an inner cross-sectional area of about 370 m 2  (4,000 ft 2 ) and an inner diameter of about 22 m (71 ft). For one thousand riding units  210 , the arena upstream end  26  has an inner cross-sectional area of about 3,700 m 2  (40,000 ft 2 ) and an inner diameter of about 69 m (226 ft). Of course, for fewer, intermediate or more riding units  210 , the inner area and diameter of the arena upstream end  26  can be readily selected by the above formula or other suitable means, as needed or desired.  
         [0070]    In one embodiment, the arena downstream end  28  (see, for example, FIGS. 1, 2 and  4 ) has an inner diameter about twice (200%) that of the arena upstream end  26 . Thus, in general, for ten riding units  210 , the arena downstream end  28  has an inner diameter of about 14 m (46 ft) and an inner cross-sectional area of about 148 m 2  (1,600 ft 2 ). For one thousand riding units  210 , the arena downstream end  28  has an inner diameter of about 44 m (142 ft) and an inner cross-sectional area of about 1,480 m 2  (16,000 ft 2 ). For one thousand riding units  210 , the arena downstream end  28  has an inner diameter of about 138 m (452 ft) and an inner cross-sectional area of about 14,800 m 2  (160,000 ft 2 ).  
         [0071]    In another embodiment, the arena downstream end  28  (FIGS. 1, 2 and  4 ) has an inner diameter in the range from about 150% to about 300% of the inner diameter of the arena upstream end  26 . In yet another embodiment, the arena downstream end  28  has an inner diameter in the range from about 120% to about 400% of the inner diameter of the arena upstream end  26 . In modified embodiments, the downstream end inner diameter may be selected in other suitable manners, as needed or desired.  
         [0072]    The arena  14  (FIGS.  1 - 4 ) has a height that is sufficient to accommodate a selected number of flying crafts  210 . The arena  14  preferably has a height of about 12 meters to about 15 meters (40 feet to 50 feet). In another embodiment, the arena  14  has a height in the range from about 8 meters to about 30 meters (25 feet to 100 feet). In yet another embodiment, the arena  14  has a height in the range from about 6 meters to about 60 meters (20 feet to 200 feet). In modified embodiments, the arena height may be selected in other suitable manners, as needed or desired.  
         [0073]    The air flow speed in the arena or air pool  14  (FIGS.  1 - 4 ) is dependent on the arena size and the configuration of the riding devices  210 . It is estimated that during operation the air flow speed in the arena  14  is in the range from about 60 km/hour (40 miles/hour) to about 300 km/hour (180 miles per/hour) though it may be less or more, as needed or desired.  
         [0074]    The top safety zone  16  (FIGS. 1 and 5) is downstream of the arena  14  and is in mechanical and fluid communication with the arena  14 . The top safety zone  16  is connected to the downstream end  28  of the arena  14 .

         [0100]    In the illustrated embodiment of FIGS. 10 and 11, the holes  224   a  are angularly offset from adjacent holes  224   a  by about 45° (π/4 radians). The holes  224   b  are angularly offset from adjacent holes  224   b  by about 45° (π/4 radians). The holes  224   c  are angularly offset from adjacent holes  224   c  by about 90° (π/2 radians). The holes  224   d  are angularly offset from adjacent holes  224   d  by about 90° (π/2 radians). In modified embodiments, the holes  224  may be offset in other manners, as required or desired, giving due consideration to the goal of achieving one or more of the benefits and advantages as taught or suggested herein.  
         [0101]    In the illustrated embodiment of FIGS. 10 and 11, the holes  224   a  are angularly offset from corresponding holes  224   b  by about 22.5° (π/8 radians). In another embodiment, the holes  224   a  are substantially aligned with corresponding holes  224   b . In modified embodiments, the holes  224   a ,  224   b  may be offset in other manners, as required or desired, giving due consideration to the goal of achieving one or more of the benefits and advantages as taught or suggested herein.  
         [0102]    In the illustrated embodiment of FIGS. 10 and 11, the holes  224   c  are angularly offset from corresponding holes  224   d  by about 45° (π/4 radians). In another embodiment, the holes  224   c  are substantially aligned with corresponding holes  224   d . In modified embodiments, the holes  224   c ,  224   d  may be offset in other manners, as required or desired, giving due consideration to the goal of achieving one or more of the benefits and advantages as taught or suggested herein.  
         [0103]    Referring in particular to FIG. 10, one or more resilient cushioning devices  232  are provided on the outer surface of the shell  212  to absorb and release impact forces during bumping of the riding devices  210  which adds the utility and enjoyment of the participants  222 . The cushion  232  may extend along the centerline plane  226  and around the shell  212 . Other cushions  232  may be placed at other suitable locations such as the top  228  or bottom  230  or may cover substantially the entire shell  212 , as needed or desired. The cushions  232  may comprise any one of a number of suitable materials such as rubber, cellular foam, inflatable bladders and the like.  
         [0104]    The outer shell  212  (FIGS. 10 and 11) is fabricated from a suitably strong and substantially transparent material such as composite plastics and thermoplastics. In modified embodiments, the outer shell  212  or portions of it may efficaciously be fabricated from other plastics, metals, alloys, ceramics, combinations thereof, and the like, as needed or desired.  
         [0105]    The riding device  210  and the outer body  212  (FIGS. 10 and 11) are dimensioned such that they may comfortably accommodate at least one participant  222 . In one embodiment, the riding device  210  and the outer body  212  have a diameter of about 1.8 m (6 feet) and a footprint of about 3.3 m 2  (36 ft 2 ). In other embodiments, the riding device  210  and the outer body  212  may be dimensioned in other manners, as needed or desired. For example, to accommodate more than one ride participant  222  in a single riding device  210 , the diameter and footprint of the riding device  210  and the outer body  212  may be larger.  
         [0106]    The seat  214  (FIGS. 10 and 11) is generally designed and configured to accommodate a rider or participant  222  and is positioned at the bottom of the device  210  to provide a low center of gravity and hence increased stability. The seat  214  includes a safety hat or helmet  234 . The hat  234  is preferably an integral part of the seat  214 . In modified embodiments, the hat  234  may be removable. The seat  214  also includes a safety belt or bar to safely restrain the participant  222  during movement of the riding device  210 . In modified embodiments, the seat can be configured or designed to accommodate more than one participant such as parents with children and the like, as needed or desired.  
         [0107]    The motion controller  216  (FIGS. 10 and 11) allows the participant  222  to pilot the air craft  210  and control its motion via actuations of the motion control system  220 . The motion controller  216  may comprise a joystick, press or push buttons, levers including foot actuated levers and combinations thereof, as needed or desired.  
         [0108]    The motion stabilizer  218  (FIGS. 10 and 11) provides balance and stability to the riding device  210  and prevents or mitigates undesirable vibrations and oscillations. The stabilizer  218  is mounted above the safety seat  214  and generally comprises a plurality of vanes or blades  236 . In the illustrated embodiment, four vanes or blades  236  are provided though fewer or more may be utilized, as needed or desired.  
         [0109]    As best seen in the top view of FIG. 11, the blades  236  are oriented at approximately right-angles (90°) to adjacent blades  236 . In modified embodiments, other suitable blade orientations may efficaciously be utilized, as needed or desired.  
         [0110]    Also, as best seen in the top view of FIG. 11, the blades  236  are angularly offset from adjacent holes  224   c  by about 45° (π/4 radians). In another embodiment, the blades  236  are substantially aligned with corresponding holes  224   c . In modified embodiments, other suitable angular offsets may efficaciously be utilized, as needed or desired.  
         [0111]    Referring in particular to FIGS. 10 and 11, the blades  236  of the motion stabilizer  218  facilitate in maintaining proper vertical alignment of the riding device  210  during motion with respect to the vertical axis or plane  238  of the riding device  210 . Hence, if there is undesirable rotation from the position shown in FIG. 10 about the plane or axis  238 , the upward air flow impinges on the large flat surface of one or more of the blades  236  causing the riding device  210  to rotate back towards its original upright position, that is, as shown in FIG. 10. Advantageously, in this manner the stabilizer  236  prevents or mitigates unwanted and undesirable vibrations and rotation of the riding device  210 .  
         [0112]    The motion control system  220  generally comprises a central or main controller  240  and a plurality of nozzles with open and shut capability utilizing corresponding flow controlling or restricting valves. As best seen in the top view of FIG. 11, these include four horizontal movement control nozzles HN 1 , HN 2 , HN 3 , HN 4  and four vertical movement control nozzles VN 1 , VN 2 , VN 3 , VN 4 . Various suitable valves may be utilized in conjunction with the nozzles, for example, butterfly valves, electronically controlled valves, valves with varying degree of open, shut and partially open-shut capability, and combinations thereof, among others, as needed or desired.  
         [0113]    Referring in particular to FIG. 11, the forward motion is controlled by activating (opening) nozzles HN 1  and HN 2 . The backward motion is controlled by activating (opening) nozzles HN 3  and HN 4 . The leftward motion is controlled by activating (opening) nozzles HN 1  and HN 3 . The rightward motion is controlled by activating (opening) nozzles HN 2  and HN 4 .  
         [0114]    Referring in particular to FIGS. 10 and 11, the upward motion (that is, upwards in the direction of axis or plane  238 ) is controlled by activating (opening) nozzles VN 2  and VN 4 . The downward motion (that is, downwards in the direction of axis or plane  238 ) is controlled by activating (opening) VN 1  and VN 3 .  
         [0115]    Referring in particular to FIG. 11, the clockwise rotation is controlled by activating (opening) HN 2  and HN 4 . The contour-clockwise rotation is controlled by activating (opening) HN 1  and HN 3 .  
         [0116]    Still referring in particular to FIG. 11, the motion in any other direction can be accomplished by combining the motions above and adjusting the airflow volume in each nozzle.  
         [0117]    Loading and Unloading of Passengers  
         [0118]    [0118]FIG. 12 illustrates one embodiment of a ride participant  222  loading scheme. The system is initially shut down and all the riding devices  210  are placed at the upstream end  26  of the air pool  14 , such as on the bottom safety zone  18 . The ride participants  222  enter the arena  14  through one or more entrance/exit gates  242  proximate the arena upstream end  26 . The participants  222  each select a riding device  210  and are secured within it. When all pilots  222  are in a ready for take-off position, the system is started. When the system reaches the appropriate air speed profile the rider units  210  move upwards and are suspended and ready for free-flying.  
         [0119]    [0119]FIG. 13 illustrates another embodiment of a ride participant  222  loading scheme. With the system is running at the operational air speed, all the riding devices  210  are placed at the top of the air pool  14  on a loading platform  244  which may be the same as the cover  34  (FIG. 5) of the top safety zone  16  or an independent unit. The participants  222  enter the system through an escalator from ground level to the top of the air pool  14 . Each participant  222  picks a riding device  210  and is secured within it. After all pilots  222  are in their position, the system releases the riding devices  210  into the air pool  14 . This may be done by slidingly moving the platform  244  or by opening hatch doors and the like. The riding devices  210  will start free-fall motion through the top safety zone  16 , and will slow down as they reach the flying zone(s) of the arena  14 . Eventually the riding devices  210  will reach their respective stable positions in the flying zone(s) and be ready for free-flying.  
         [0120]    [0120]FIG. 14 illustrates another embodiment of a ride participant  222  loading scheme. While the system is running at the operational air speed, all the riding devices  210  are placed on a conveyor  246  that passes through the air pool  14 . The participants  222  enter into respective riding devices  210  outside the air pool  14  and on the conveyor  246 . When all the pilots  222  are in their position, the conveyor transports all the riding devices  210  into the air pool  14  sequentially. In the air flow, all the riding devices  210  will move upwards and are suspended and ready for free-flying.  
         [0121]    [0121]FIG. 15 illustrates one embodiment of a ride participant  222  unloading scheme. With the riding devices  210  suspended or flying, the air speed within the air pool  14  is gradually reduced and each pilot  222  guides his or her riding device  210  to land onto a landing position on the ground or bottom safety zone  18 . In the event a pilot  222  is unable to handle the landing maneuvers, an operator takes over the pilot control through the override mode (as discussed above) and guides the riding device  210  into a landing position. After all pilots  222  are in their position, the system opens one or more exit gates  242  and all pilots  222  exit out of the air pool  14  safely.  
         [0122]    [0122]FIG. 16 illustrates another embodiment of a ride participant  222  unloading scheme. The system gradually reduces its air speed and each pilot  222  guides his or her riding device  210  to land onto a generally slow moving conveyor  246  proximate the upstream end  26  of the air pool  14 . In the event a pilot  222  is unable to properly land onto the conveyor  246 , a ground operator takes over the pilot control using the override mode (as discussed above) and lands the riding device  210  on the conveyor  246 . The conveyor  246  transports the riding device  210  with the pilots  222  out of the arena  14  one by one or sequentially. The conveyor  246  momentarily stops to release the pilot  222  in the riding device  210  and the pilot  222  is released outside the air pool  14  safely. Once the pilot  222  is released, the conveyor  246  resumes its transportation until all the riding devices  210  are transported out of the air pool  14 .  
         [0123]    [0123]FIG. 17 illustrates yet another embodiment of a ride participant  222  unloading scheme. The system operates at its operational air speed and each pilot  222  guides his or her riding devices  210  into an exit gate  250  to land onto a generally slow moving conveyor  248  located in one of the flying zone areas. In the event a pilot  222  is unable to guide his or her riding device  210  into the exit gate  250 , a ground operator takes over the pilot control using the override mode (as discussed above) and guides the riding device  210  to the exit gate  250 . The conveyor  248  transports the riding device  210  and pilots  222  onto the ground.
