• the waterslide 1 comprises a bowl 3, first and second chutes 5, 7 and a spiral staircase 9.
• the waterslide 1 may be used, for example, in a leisure or amusement park.
• the bowl 3 has a generally oval plan form and is approximately 13.5 meters long and approximately 9.5 meters wide. While various dimensions are described herein, those skilled in the art will appreciate that other dimensions may also be appropriate.
• the bowl 3 has a sidewall 11 formed from a series of moldings supported on a metal framework 13.
• a rim 15 is provided around an upper edge of the bowl 3, and an aperture 17 is formed in the center of the bottom of the bowl 3.
• the rim 15 curves inwardly, and a middle region of the sidewall 11 below the rim 15 is substantially vertical.
• the lower region of the sidewall 11 slopes downwardly towards the aperture 17.
• a first rider entrance 19 is provided at a first end of the bowl 3, and a second rider entrance 21 is provided at a second end thereof.
• the first and second rider entrances 19, 21 are provided proximal the upper edge of the bowl 3 and are arranged generally tangential to its circumference.
• the first and second chutes 5, 7 are connected to the first and second rider entrances 19, 21 such that riders R, R' may slide down the chutes 5, 7 and enter the bowl 3.
• the momentum of the riders R, R' allows them to travel at least partway around the bowl 3 before exiting through the aperture 17.
• the first and second chutes 5, 7 comprise upper sections 23, 23', mid-sections 25, 25' and lower sections 27, 27'.
• the upper sections 23, 23' are positioned above the center of the bowl 3 and are inclined at approximately 15° to the vertical.
• the mid-sections 25, 25' and the lower sections 27, 27' in plan form curve through approximately 270° to guide the riders R, R' to the rider entrances 19, 21.
• the lower sections 27, 27' are arranged substantially horizontally such that the riders R, R' enter the bowl 3 travelling substantially parallel to the rim 15.
• the term chute is used herein to refer to slides, flumes, and the like.
• the staircase 9 leads to a gantry 29 where a launch station 31 is located.
• the launch station 31 comprises first and second pivotally mounted platforms 33, 35.
• a pair of riders R, R' enters the launch station 31 from the side and each stand on their respective platforms 33, 35.
• a launch mechanism 37 is provided for pivoting the platforms 33, 35 between an extended position and a retracted position (shown in dashed lines in Figure 4).
• the launch mechanism 37 is configured to ensure that the platforms 33, 35 pivot to their retract positions generally simultaneously, thereby ensuring that the riders R, R' are launched together.
• the launch mechanism in the embodiment of Figure 4 comprises a lever 39 to be actuated manually, for example by an operator; but the mechanism 37 could be automated.
• the launch station 31 may be provided with means to allow the riders R, R' to confirm that they are ready to be released. For example, the riders R, R' may be required to each press a respective button 41 , and once both buttons 41 have been pressed, the message "READY" may be displayed on screens 43, and countdown timers 45 may activate.
• the framework 13 supports the bowl 3 and the staircase 9 and may, for example, be of conventional construction.
• the gantry 29 is mounted on a pair of vertical columns.
• a first set of tethered cables 49 may be provided.
• a second set of cables 51 may additionally (or alternately) extend from the gantry 29 to support the upper sections 23, 23' and the mid-sections 25, 25' of the chutes 5, 7.
• a splash pool 53 ( Figure 2) may be provided below the bowl 3 so that the riders R, R' exit the bowl 3 through the aperture 17 and fall into the pool 53.
• a filtration system 55 may be provided to treat the water in the pool 53, and may be provided with a pump (not shown) to pump the water to the top of the chutes 5, 7 via a pipe 57.
• a pump not shown
• water may be continuously introduced into the top of the chutes 5, 7 so that there is a steady stream of water down the chutes 5, 6.
• Water may also be pumped to a perforated conduit extending around the rim 15 to wet the interior surface of the bowl 3 to reduce friction.
• a water spray may be provided to provide lubrication.
• a heater may be provided in the filtration system 55 to heat the water.
• the riders R, R' travel down the chutes 5, 7 and both enter the bowl 3 at substantially the same time.
• the riders R, R' are travelling substantially horizontally when they exit the lower sections 27, 27' of the chutes 5, 7 and enter the bowl 3 through the first and second rider entrances 19, 21 respectively.
• the rider entrances 19, 21 are located near the rim 15 of the bowl 3 and the momentum of the riders R, R' allows them to travel at least partway around the bowl 3.
• the riders R, R' are unlikely to collide with each other as they travel around the bowl 3. If a first rider R is travelling quicker than a second rider R', then the quicker first rider R will be higher up the sidewall of the bowl 3 than the slower second rider R'. Thus, if the first rider R is travelling sufficiently quickly to catch up with the second rider R', the riders R, R' will be at different heights. [0034] The riders R, R' slow down due to frictional forces, and the reduced centripetal forces cause them to travel towards the bottom of the bowl 3. The riders R, R may come to rest at the bottom of the bowl 3, or they may slide directly through the aperture 17 and enter the pool 53.
• the riders R, R' may then exit the waterslide 1 at the side of the pool 53.
• a divider or partition (not shown) may be provided in the middle of the aperture 17. The likelihood of the riders R, R' colliding with each other is reduced since the divider or partition keeps them apart if they enter the pool 53 from opposite sides of the aperture 17.
• a jet of water may be provided in the pool 53 to move the riders R, R' away from the area below the aperture 17 once they are in the water.
• the jet of water may be provided in the middle of the pool 53 and directed upwardly, thereby causing the water at the top of the pool 53 to move out towards the edges of the pool 53.
• the jet of water will thereby move the riders R, R towards the sides of the pool 53.
• a waterslide 101 according to another embodiment of the present invention is shown in Figures 5 and 6.
• the waterslide 101 corresponds in many ways to the waterslide 1 shown in Figures 1-4, and like reference numerals have been used for like components, albeit incremented by 100 for clarity.
• the waterslide 101 comprises a bowl 103 into which riders are introduced.
• the bowl 103 is shown to be circular rather than oval, and the waterslide 101 comprises three chutes 105, 106, 107 down which three riders travel
• the riders enter the bowl 3 through three rider entrances 1 19, 120, 121 equally spaced around the circumference of the bowl 103 (i.e. spaced apart from each other by approximately 120°).
• the launch station (not shown) may be modified from the launch station 31 to launch the three riders into the respective chutes 105, 106, 107 at substantially the same time.
• a further distinction between embodiments 1, 101 is that the bowl 103 is not provided with an aperture 17 in its base. Rather, a shallow pool 153 is formed in the base of the bowl 3 and the riders drop directly into the pool 153. This arrangement may be desirable since the pool 153 does not have to be as deep as the pool 53. Thus, an individual who is not a confident swimmer can ride the waterslide 101 and then stand up in the pool 153.
• a second spiral staircase 159 is provided in the middle of the pool 153 leading to a platform 161 to allow a rider to exit the waterslide 101.
• a waterslide 201 according to yet another embodiment of the present invention is shown in Figures 7 to 10.
• the waterslide 201 corresponds in many ways to the waterslide 1 shown in Figures 1 to 4, and like reference numerals have been used for like components, albeit incremented by 200 for clarity.
• the waterslide 201 comprises a bowl 203 into which riders R, R' are introduced. As shown most clearly in Figure 7, the bowl 203 is circular and the two rider entrances 219, 221 are opposed from each other.
• the launch station 231 is provided on a gantry 229 accessed via a staircase 209, as shown in Figure 8. The launch station 231 is adapted to launch two riders R, R into the respective chutes 205, 207 at substantially the same time. An enlarged side view of the launch station 231 is shown in Figure 9. Although the launch station 231 is shown with the riders R, R standing back-to-back, it will be appreciated that they may face each other prior to launch.
• the bowl 203 has a shallow pool 253 formed in the base thereof, similar to the arrangement in the waterslide 101.
• the riders R, R may walk through the pool 253 to the centrally located spiral staircase 259.
• the chutes 205, 207 have a substantially circular cross-section, but it will be appreciated that different cross-sections, for example oval cross-sections, may also be appropriate. Moreover, the chutes 205, 207 may be open in sections or along a portion of their length.
• the bowl 203 has an inwardly directed rim 215, as shown in Figure 10.
• the waterslides and bowls described herein may be adapted to be ridden by a rider travelling on a craft, such as an inflatable inner ring or the like. Further, while embodiments have been described with particular reference to waterslides, it will be appreciated that the elements and features described herein may be applied to other leisure rides. For example, a rider may travel on a waxed fabric bag or a waxed fabric mat without the aid of flowing water.
• the bowl described herein may form only part of a larger system. For example, a rider may exit the bowl and enter another chute or slide.
• FIGS 1 1 through 13 show an exit system 500 that may be incorporated into a leisure slide, including those shown in Figures 1 through 10.
• the system 500 may replace the aperture 17 and the pool 53 in the embodiment of Figures 1 through 4.
• the exit system 500 has a pool 502 at a base 504 of the bowl and a housing 510 with two exit ports 512, 512' at offset (e.g., generally opposed) angles.
• the pool 502 surrounds the housing 510 and is created by a shallow ridge 503 at the entrance to the ports 512, 512' that is higher than the base 504 of the bowl.
• the housing 510 is shown to be generally semi-spherical, though other shapes may alternately be used.
• the angle between the exit ports 512, 512' may be generally equivalent to an angle between entrances (e.g., entrances 19, 21).
• the exit ports 512, 512' are sized to allow the riders R, R' to pass through, and lead to exit slides (or "chutes") 514, 514' designed to take the riders R, R 1 clear of the bowl or on to another part of the ride, aided by the flow of water from the pool 502.
• the chutes 514, 514' may pass closely to one another, it may be desirable for the chutes 514, 514' to have side walls that prevent undesirable contact between the riders R, R'.
• the two exit ports 512, 512' may allow two riders R, R' to generally simultaneously exit the bowl while travelling in different (e.g., generally opposite) directions.
• multiple riders may generally simultaneously enter the bowl while travelling in different directions, and may generally simultaneously exit the bowl while travelling in different directions.
• the riders may travel in a common overall direction (i.e., all of the riders may travel clockwise, or all of the riders may travel counter-clockwise).
• the ride may accordingly be safe for multiple users at one time, and may be cleared much quicker for use by subsequent users compared to rides with a single exit.
