Description
FILE NO. 75956-96 WATER SLIDE
Field The invention relates in general to water slide rides, and more particularly, to a water slide ride having a sliding wall.
Background Water slides are popular ride attractions for water parks, theme parks, family entertainment centers and destination resorts. Water slides not only offer welcome relief from the summer heat, they also provide an exciting and entertaining diversion from conventional pool and/or ocean bathing activities.
In one type of water slide, a bather or rider slides his body and/or a flexible riding mat, tube or raft ("ride vehicle") along a downward-inclined sliding surface defined by a flume or water channel that bends, twists and turns following a predetermined ride path. The flume also typically carries a flow of water from a starting pool at some desired higher elevation to a landing pool or run-out at a desired lower elevation. The water is typically continuously recirculated from the lower elevation to the higher elevation using one or more pumps and then continuously falls with gravity from the higher elevation to the lower elevation flowing along the slide/flume path. The water provides cooling fun for the ride participants, and also provides a lubricious film or fluid between the rider/vehicle and the ride surface so as to increase the speed of the rider down the flume path.
The popularity of water slides has increased dramatically over the years, as they have proliferated and evolved into ever larger and more exciting rides. For example, ' 75956-96

Detailed Description Figures 1, 2 and 3 depict a water slide feature 10.
The water slide feature 10 includes a sliding surface 12. The sliding surface 12 has an entry 14 and an exit 16. The entry 14 is at an entry end 15 of the sliding surface 12 and the exit 16 is at and opposite exit end 17 of the sliding surface 12.
The entry 14 and the exit 16 are both positioned on the same side of the sliding surface 12. In other words, the entry 14 and the exit 16 lie substantially in opposite directions but may be angled outward. For example, the entry 14 may be angled approximately 10 to 15 degrees outward from the entry end 15 and the exit 16 may be angled about 5 degrees outward from the exit end 17.
The sliding surface 12 comprises a wall 18. The wall 18 includes a bottom 20, and equator line 22 and a top 24. A
cone or funnel shape 26 in stippled lines has been added to Figure 1 to aid in describing the shape of the sliding surface 12. It will be understood that the complete cone or funnel shape 26 is not part of the water slide feature 10. The water slide feature 10 comprises only what is shown in solid lines.
The funnel shape 26 tapers from a wide end 28 to a narrow end 30. In this embodiment, the funnel shape 26 is a right angle funnel shape; however, non-right angle funnel shapes may form the basis of the shape of the sliding surface 12 of the water slide feature 10. The wide end 28 of the funnel shape 26 is at the entry end 15 of the sliding surface 12 and the narrower end 30 of the funnel shape 26 is at the FILE NO. 75956-96

- 8 -exit end 17 of the sliding surface 12. The shape of the wall 18 is defined by the shape of the funnel shape 26. In particular, the wall 18 follows a shape which is a portion of the shape of the funnel shape 26. The wall 18 starts at a longitudinal axis defined by the bottom 20, which is a line down a side of the funnel shape 26. The wall 18 extends up following a side of the funnel shape 26 up past a 90 degree angle to the horizontal which may also be at a 90 degree angle to the longitudinal axis. For example, the wall may encompass an approximately 105 degree portion of the funnel shape 26. In the present embodiment, which is based on a right angle funnel, the longitudinal axis 20 and the equator line 22 define a plurality of pairs of points separated by a semi-circular arc of 90 degrees. The semi-circular arcs have a radius of curvature that reduces from the entry end 15 to the exit end 17 of the slide feature 10.
The bottom 20 is a lowest edge of the wall 18. The bottom 20 may be inclined slightly downward from the entry end 15 to the exit end 17 as best can be seen in Figures 2 and 3.
In some embodiments, the lowermost surface of the sliding surface is inclined from horizontal descending from the entry end to the exit end at an angle of between 0 and 45 degrees from the horizontal. In some embodiments, the angle is about 5 degrees.
From the bottom 20 the wall 18 curves upward along a shape defined by the side of the funnel shape 26 up to a top 24. The entire shape of the wall 18 may be defined by the shape of the funnel shape 26. It will be appreciated, however, that the wall 18 is not the entire length of the side of the funnel shape 26. The wall 18 is only a portion of the side of the funnel shape 26.

The bottom 20 is a lowest edge of the wall 18. The bottom 20 may be inclined slightly downward from the entry end 15 to the exit end 17 as best can be seen in Figures 2 and 3.
In some embodiments, the lowermost surface of the sliding surface is inclined from horizontal descending from the entry end to the exit end at an angle of between 0 and 45 degrees from the horizontal. In some embodiments, the angle is about 5 degrees.
From the bottom 20 the wall 18 curves upward along a shape defined by the side of the funnel shape 26 up to a top 24. The entire shape of the wall 18 may be defined by the shape of the funnel shape 26. It will be appreciated, however, that the wall 18 is not the entire length of the side of the funnel shape 26. The wall 18 is only a portion of the side of the funnel shape 26.

- 9 -The wall 18 extends past the equator line 22. The equator line 22 defines a line upon which the wall 18 is at a 90 degree angle or perpendicular to the horizontal. Above the equator line 22, as the wall 18 follows the funnel shape 26, the wall 18 curves inward and is at an angle of more than 90 degrees to the horizontal.
The funnel shape 26 has an axis of curvature 32. The axis of curvature 32 is the geometric axis of curvature about which the funnel shape 26 is curved. In a right angle funnel, the axis extends through the centre of the funnel. It will be appreciated that, because the wall 18 is a portion of the funnel shape 26, the wall 18 also curves about the same axis of curvature 32. A distance 25 (see Figure 3) from the wall 18 to the axis of curvature 32 is the radius of curvature. It will be appreciated that the radius of curvature decreases from the wide end 28 to the narrow end 30 of the funnel shape.
Consequently, the radius of curvature decreases from the entry end 15 to the exit end 17 of the sliding surface 12. The wall 18 therefore defines a reducing radius slide feature.
This reducing radius of the slide feature 10 helps to maintain the rider on the water slide feature 10 in contact with the water slide even when the rider travels above the equator line 22.
In this embodiment, the rider is accelerated and directed onto the sliding surface 12 through the downwardly inclined slide portion to the entry 14 by gravity. The path the riders will travel over the wall 18 will depend on a number of factors such as their weight and their distribution of their mass. In some embodiments the riders may travel in a ride vehicle, for example, a raft for one to six people or more. In other embodiments, the riders may body slide without a raft.

In a right angle funnel, the axis extends through the centre of the funnel.

It will be appreciated that the radius of curvature decreases from the wide end 28 to the narrow end 30 of the funnel shape.
Consequently, the radius of curvature decreases from the entry end 15 to the exit end 17 of the sliding surface 12. The wall 18 therefore defines a reducing radius slide feature.

- 10 -In Figure 2, a first ride path 34 and a second ride path 36 are marked. These ride paths 34 and 36 are exemplary ride paths only. In both ride paths 34 and 36, the rider enters the sliding surface 12 through the entry 14 at the entry end 15. The rider then travels across the bottom 20 of the wall 18 then up the wall 18 while simultaneously travelling laterally across the wall 18. The rider then reaches a high point and begins to travel down the wall 18 while still traveling laterally across the wall 18 from the entry end 15 towards the exit end 17 and then out through the exit 16 at the exit end 17. On the first ride path 34, the rider does not travel above the equator 22 and on the second ride path 36 the rider does travel above the equator 22 and thus travels above a 90 degree angle with the horizontal. In other words, the rider travels through the vertical when travelling the second ride path 36. The riders are continuously moving on the wall 18.
The riders do not stall or stop at the maximum height of travel because the riders are always moving across the wall 18 on a continuously curving path.
The ride paths 34 and 36 are not pre-selected. The path the rider travels will depend on a variety of factors;
however, the ride path is predictable to the extent that the reducing radius shape of the wall 18 ensures that the riders will stay on the wall 18 irrespective of whether or not they travel above the equator line 22. Also, both ride paths direct the rider to the exit 16.
In this embodiment, the wall 18 has a partially ellipsoid, side and top perimeter as best seen in Figure 2.
Around the side and top perimeter is a safety lip 38. The safety lip 38 has a concave semi-circular cross-section with a radius of curvature of, for example, 2 feet. The rider will not normally ride on the safety lip 38. The safety lip 38 is provided only for safety reasons and may be omitted.

- 11 -In this embodiment, the size of the water slide feature 10 is based on a funnel shape which has a diameter at the wide end 20 of 100 feet. In other words, a radius of curvature of 10 to 50 feet and may be about 30 feet. The funnel shape 26 tapers to a diameter of 4 to 20 feet at the exit or, in other words, a radius of curvature of 2 to 10 feet and may be about 6 feet. The radius of curvature of the sliding surface at the entry end may be substantially larger than the radius of curvature of the sliding surface of the exit end. The ratio of the radius of curvature of the entry end to the exit end may be between 8:1 and 3:1 or between 6:1 and 4:1 or about 5:1.

For example, in one embodiment, the width of the wall 18 at the bottom 20 from the entry end 15 to the exit end 17 is approximately 40 feet and the entry 14 and the exit 16 are approximately 14 feet wide. This means that the entry 14 and the exit 16 are less than one half, and even less than one third of the width of the wall 18. In such an embodiment, the height of the wall from the bottom to the top may be approximately 40 feet.

- 13 -further beyond the equator line 82 (the line at which the wall 78 is at a 90 degree angle to the horizontal) then in the first embodiment. This permits the safety wall to be omitted from the top of the water slide in this embodiment. Instead, in this embodiment, inwardly curved safety walls 88 are found only along the sides of the wall 78. Additionally, in this embodiment, the riders are accelerated along a horizontal entry portion which connects to the entry 74 and accelerates the rider up the wall 18. This may, for example, constitute a linear induction motor system.
Although the illustrated embodiments show a wall defined by the shape of a funnel, for the portions of the wall which the rider will not travel on, there may be holes cut or other wall shapes that may deviate from the funnel shape. For example, a wave shape could be added at the top 84.
In some embodiments, the lowermost surface of the wall may not include the lowermost portion of the funnel shape. The lowermost surface of the wall could begin part way up the side of the funnel. In such embodiments, the equator line will still be 90 degrees to the horizontal but the angle between the lowermost surface and the equator line may be less than 90 degrees. This could be the case, for example, if a linear induction motor were used to accelerate a raft up an entry onto the wall as described in U.S. patent application no. 11/681,720, filed March 2, 2007, entitled "Linear Motor Driven Waterslide Ride and Method".
In Figure 4, the exit slide portion 54 is a generally downwardly sloping flume type slide portion. However, other exits portions are possible.

- 14 -portion or an upwardly inclined slide portion that may be flume type or may be open, such as a mirror image of the slide feature 10 or 70. Figures 6 and 7 depict a curving angled slide feature 90 which may be the exit slide portion from the slide feature 10 or 70 or may form a portion of any water slide.
Turning first to the side view depicted in Figure 6, the curving angled slide feature 90 includes an entrance 92, an upwardly angled section 94, a transition section 96, a downwardly angled section 98 and an exit 100. The curving angled slide feature 90 has a sliding surface 102. In this embodiment, the upward incline of the upwardly angled section 94 is an approximately 7 percent rise and the decline of the downwardly angled section 98 is approximately the same.
However, the angle of incline may differ and be, for example 4 to 12 percent or more or less with an incline and subsequent decline of 3 to 12 feet over its length. Also the angle of incline and the angle of decline need not be the same and need not be constant over the entire length. For example, the section 98 may be horizontal. The transition section 96 is the section at which the upward angle changes to horizontal and then goes to the declined angle.
Turning to Figure 7, a top view of the curving angled slide feature 90 is shown. From this view it can be seen that in addition to angling upward and downwards, the curving angled slide feature 90 also curves laterally outward and inward in an S-type curve. In particular, starting at the entrance 92, the upwardly angled section 94 curves outward in one direction to a maximum outward curve 104 and then curves back inward. The curving angled slide feature 90 straightens out briefly in the transition section 96. The downwardly angled section 98 then curves outward to a maximum outward curve 104 in an opposite direction to the curve in the upwardly angled section 94 and FILE NO. 75956-96

The sliding surface 102 may be a flume type sliding surface. Such a slide surface is concave with upwardly curving side walls. In some embodiments, the cross section across the sliding surface 102 may be elliptical, may be semicircular, may have a compound radius made up of four curvatures or more, or may be more squared as long as there is a bottom surface for a rider to slide on and side walls to direct the rider along the sliding path. The sliding surface 102 is lubricated with water which may enter and exit through the entrance 92 and the exit 100 or may be otherwise sprayed or introduced to the sliding surface 102.
The height of the side walls will depend on various factors including the incline and decline angles and the speed at which the rider enters the curving angled slide feature 90.
It will be appreciated, that with an elliptical or semicircular cross-section, the rider may ride part of the way up the side walls, particularly at the bend in the outward curves 104 and 106. The side walls may therefore be higher at these locations. For example, the side wall may generally be 3 to 5 feet in height but may gradually increase around on the outer side of the curves to reach 9 feet at the maximum outward curves 104 and 106.
Numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
