ABSTRACT:
FIELD OF THE INVENTION
The invention relates to amusement devices. More particularly, the invention relates to amusement devices sufficiently large so as to carry passengers and be placed in amusement parks and public recreation areas. Even more particularly, the invention relates to amusement rides, such as water slides, which use water to enhance the sliding of passengers or individual riders down substantially predetermined pathways.
BACKGROUND OF THE INVENTION
Slides, with or without the addition of water on the sliding surface thereof, which allow passengers or riders to slide downwardly into a stationary or moving body of water, have long been known.
Typically, early slides had relied on substantially straight downwardly slopped passageways in which the riders slid.
Previous improvements in the prior art slides include my earlier U.S. Pat. No. 5,137,497 to Dubeta, issued Aug. 11, 1992.
As the size of slide apparatuses (such as shown in my U.S. Pat. No. 5,137,497) increases, and the cost of labor and borrowing money increase, there is a requirement for a slide apparatus that can accommodate an even greater number of people in a shorter period of time.
The provision of such an improved slide apparatus would have the added benefit of shortening the time which passengers must wait in line. Such waiting is, needless to say, unacceptable to the majority of passengers; i.e., amusement park goers.
Accordingly, it can be seen that there is a need for a slide apparatus which can overcome these and other drawbacks of known devices.
OBJECTS AND SUMMARY OF THE INVENTION
It is an object of the invention to overcome the drawbacks of prior art slide apparatuses.
It is a further object of the invention to provide a slide apparatus which has a greater passenger throughput per hour than known devices, thereby shortening wait times for passengers, increasing the amusement value of the device, and maximizing the value of the installed device.
It is a further object of the invention to increase passenger throughput, yet without requiring greater water usage than existing devices.
A still further object is to lengthen the period of time during which a passenger is sliding, yet without increasing water usage, energy requirements, and space requirements, for example.
A further object of the invention is to provide an environmentally friendly water slide apparatus owing to its achieving the above objects of increased passenger throughput without increased demands for water, energy, and space, for example.
Another object of the invention is to provide a water slide having increased excitement value for the passengers, owing to its use of one or more switchback or “sidewinder” elements.
Yet another object of the invention is to provide a slide apparatus that changes the direction of travel of passengers in a small space, yet without the use of a dividing wall to separate passengers traveling in different (and even “opposite”) directions.
A further object of the invention is to provide a slide apparatus which prevents users from engaging or “bouncing off” the sides of the pathways or trough, while achieving the desired speeds, excitement, and rapid changes of direction.
In summary, the invention is directed to a slide apparatus including at least one trough defining at least one path along which a passenger travels, and at least one switchback trough or switchback operatively connected to the trough.
The invention is likewise directed to a slide apparatus having at least one path of travel along which a passenger travels, and at least one switchback which changes the direction of travel of the user without the use of a portion of a spiral path to accomplish the change of direction.
The invention is directed to a switchback configured for directing passengers in different directions, yet without the use of a dividing wall to separate two(2) paths along which the user travels; i.e., a first path along which the user travels in the first direction, and a second path along which the user travels in a second (e.g., return direction).
It will be appreciated that relative terms such as up, down, left, and right are for convenience only, and are not meant to be limiting. The term user, for example, is intended to encompass all users, whether individual passengers sliding directly on the slide apparatus, sliding on a film or bed of water, sliding in a stream of water, sliding on conveyances, being carried mechanically along the slide apparatus, sliding on boats or tubes, or multiple passengers sliding with or without the use of conveyances.
Still further, the term “trough” is not intended to be limited to trough-like pathways along which a user may slide. The term trough, throughout the written description and claims, is intended to encompass all manners of pathways along which a user can slide, with or without accompanying water, and with or without the use of a conveyance on which the user travels.
